The History
of Aspartame
1964
The development of new pharmaceuticals was the focus of research at the
international pharmaceutical company, G.D. Searle and Company (Farber
1989, page 29). A group working on an ulcer drug was formed including
Dr. Robert Mazer, James Schlatter, Arthur Goldkemp and Imperial Chemical.
In particular, they were looking for an inhibitor of the gastrointestinal
secretory hormone gastrin (Stegink 1984a).
1965
In 1965, while creating a bioassay, an intermediate chemical was synthesized
-- aspartylphenylalanine-methyl-ester (aspartame). In December of
1965, while James Schlatter was recrystalling aspartame from ethanol,
the mixture spilled onto the outside of the flask. Some of the powder
got onto his fingers. Later, when he licked his fingers to pick up
a piece of paper, he noticed a very strong sweet taste. He realized
that the sweet taste might have been the aspartame. So, believing
that the dipeptide aspartame was not likely to be toxic, he tasted
a little bit and discovered its sweet taste (Stegink 1984a, page
4). The discovery was reported in 1966, but there was no mention
of the sweetness (Furia 1972).
1969
The investigators first reported the discovery of the artificial sweetener
in the Journal of the American Chemical Society stating (Mazur 1969):
" We wish to
report another accidental discovery of an organic compound with a profound
sucrose (table sugar) like taste . . . Preliminary tasting showed this
compound to have a potency of 100-200 times sucrose depending on concentration
and on what other flavors are present and to be devoid of unpleasant
aftertaste."
Today, hundreds
of millions of Americans, and millions more world-wide, consume foods
and soft drinks stamped with the NutraSweet "swirl", dump
packets of Equal in their coffee, and consume NutraSweet-flavored cereal,
puddings, gelatins, cheesecake, chewing gum, diet soft drinks, children's
vitamins, chilled juices, and 9,000 other products.
So, what is aspartame,
a.k.a. NutraSweet, Spoonful, Equal...etc.? aspartyl phenylalanine-methyl
ester.
Aspartame (C14H18N2O5
) is a compound of three components. These components are methanol,
aspartic acid and phenylalanine (the latter being free form amino acids).
Methanol (methyl
alcohol or wood alcohol) is a colorless, poisonous, and flammable liquid.
It is used for making formaldehyde, acetic acid, methyl t-butyl ether
(a gasoline additive), paint strippers, carburetor cleaners for your
car's engine, and chloromethanes, et al. This poison can be inhaled
from vapors, absorbed through the skin, and ingested.
Methanol is the
type of alcohol you read about when people become blind from drinking
it. In aspartame, methanol poisoning and poisoning from methanol's
breakdown components (formaldehyde and formic acid) can have widespread
and devastating effects. This occurs in even small amounts, and is
especially damaging when introduced with toxic, free-form amino acids,
called excitotoxins.
Methanol is quickly
absorbed through the stomach and small intestine mucosa. The methanol
is converted into formaldehyde (a known carcinogen). Then, via aldehyde
hydrogenase, the formaldehyde is converted to formic acid. These two
metabolites of methanol are toxic and cumulative.
Phenylalanine is
an amino acid. Well, amino acids are good for us, right? Don't they
keep us healthy? The answer is yes, amino acids are necessary for good
health, EXCEPT when you separate the individual amino acid from its
protein chain, and use it as an "isolate" or by itself.
The Aspartic acid,
in aspartame, is also an excitotoxin. An excitotoxin, is a deleterious
substance that excites or over-stimulates nerve cells. This occurs
in the brain, as well as the peripheral nerves, because aspartic acid,
in free form, is an absorption accelerant & easily crosses the
blood-brain barrier.
This pathological
excitation of nerve cells creates a breakdown of nerve function, as
we will see. Basically, they are a group of compounds that can cause
special neurons within the nervous system to become overexcited to
the point that these cells will die.
That's right, they
are excited to death. Excitotoxins include such things as monosodium
glutamate (MSG), aspartate, (a main ingredient in NutraSweet), L-cysteine
(found in hydrolyzed vegetable protein) and related compounds.
What makes this
all the more intriguing is that "excitotoxins" appear to
play a key role in degenerative nervous system diseases such as Parkinson's
disease, Alzheimer's disease, Huntington's, ALS (Lou Gehrig's disease)
and many others.
But the story doesn't
stop there. It appears that an imbalance of these excitotoxins during
critical periods of brain development can result in an abnormal formation
of brain pathways; that is, a "miswiring of the brain." This
may lead to serious disorders such as behavioral problems (hyperactivity,
aggression, attention deficit disorders, learning disorders, poor learning
ability, and ADD)-and a lifetime of endocrine problems such as menstrual
difficulties, infertility, and premature puberty.
One of the earliest
observations seen in animals exposed to large doses was gross obesity.
Some neuroscienttists have voiced concern that America's explosion
of childhood obesity may be related to excitotoxins in food.
Aspartame creates
altered brain function, nerve damage, and systemic organ complications.
Information collected reveals that aspartame clinically exacerbates
any borderline (even yet undetected) predisposing illness, and absolutely
complicates certain known medical illnesses like Lupus, Multiple Sclerosis,
Parkinson's, diabetes, retinopathies, allergies, mentation disorders,
etc. (See list of symptoms 1)
Aspartame is a toxin,
and is unique in this hazardous respect. This in NOT an allergic reaction,
but rather a true toxin. No other food can be provided as a comparison
to the toxic nature of NutraSweet. Upon closer examination, the available
research revealed that the manufacturer (Monsanto) and the FDA are
manipulating the public (via the media) into thinking that aspartame
is safe. It is not. As an American who trusted the system we all created,
as an American who worked for the system, it made me angry that public
health has taken a backseat to greed. This is the "engine" that
perpetuated this epidemic: the collusion of our government with multi-national
conglomerate influence.
G.D. Searle approached
Dr. Harry Waisman, Biochemist, Professor of Pediatrics, Director of
the University of Wisconsin's Joseph P. Kennedy Jr. Memorial Laboratory
of Mental Retardation Research and a respected expert in phenylalanine
toxicity, to conduct a study of the effects of aspartame on primates.
The study was initiated on January 15, 1970 and was terminated on or
about April 25, 1971. Dr. Waisman died unexpectedly in March, 1971.
Seven infant monkeys
were given aspartame with milk. One died after 300 days. Five others
(out of seven total) had grad mal seizures. The actual results were
hidden from the FDA when G.D. Searle submitted its initial applications.
G.D. Searle denied
knowledge of or involvement with the initiation, design or performance
of the study. Yet, false results were submitted to the FDA like the
rest of the 150 G.D. Searle studies (on aspartame and other products),
bearing a Searle Pathology-Toxicology project number. Both Dr. Waisman
and G.D. Searle were responsible for the study design. A number of
false statements were made by G.D. Searle including that the animals
were unavailable for purchase for autopsy after the termination of
the study.
The FDA banned the
sweetener cyclamate, 1969. Robert Scheuplein, who was the acting Director
of FDA's Toxicological Services Center for Food Safety and Applied
Nutrition was quoted as saying "the decision was more a matter
of politics than science."
Neuroscientist and
researcher John W. Olney found that oral intake of glutamate, aspartate
and cysteine, all excitotoxic amino acids, cause brain damage in mice
(Olney 1970). Dr. John W. Olney informed G.D. Searle that aspartic
acid caused holes in the brains of mice.
Ann Reynolds, a
researcher who was hired by G.D. Searle and who has done research for
the Glutamate (MSG) Association, and was asked to confirm Dr. Olney's
tests. Dr. Reynolds confirmed aspartame's neurotoxicity in infant mice.
Excitotoxic compounds
like MSG, aspartate, cysteine seem to create hypothalamic lesions,
particularly in young animals. The reason for the latter is likely
the fact that the blood brain barrier closes most slowly (if ever completely)
around structures like hypothalamus. The outcome for such animals (rats)
was obesity,severe behavioral changes, etc.
G.D. Searle did
not inform the FDA of this study until after aspartame's approval.
None of the tests submitted by G.D. Searle to the FDA contradicted
these findings (Olney 1970, Gordon 1987, page 493 of US Senate 1987).
An internal G.D.
Searle memo laid out the strategy for getting aspartame approved (Helling
1970):
At this meeting
[with FDA officials], the basic philosophy of our approach to food
and drugs should be to try to get them to say, "Yes," to
rank the things that we are going to ask for so we are putting first
those questions we would like to get a "yes" to, even if
we have to throw some in that have no significance to us, other than
putting them in a yes saying habit.
We must create affirmative
atmosphere in our dealing with them. It would help if we can get them
or get their people involved to do us any such favors. This would also
help bring them into subconscious spirit of participation.
(Refer to Actual
Letter...2)
1972
FDA Toxicologist Dr. Adrian Gross came upon some irregularities in the
submitted tests of the G.D. Searle drug Flagyl. G.D. Searle did not
respond for another two years. Their response raised serious questions
about the validity of their tests (Gross 1975, page 35)
1973
On March 5, 1973, G.D. Searle's petition to the FDA for approval to market
aspartame as a sweetening agent was published in the Federal Register
(1973).
On March 21, 1973
the MBR report was submitted to G.D. Searle. Background: In August
of 1970, G.D. Searle conducted two 78- week toxicity studies on rats
for what was to become a best-selling heart medication, Aldactone.
One study was conducted at G.D. Searle and one at Hazelton Laboratories.
In March 1972, the
rats for autopsied and the pathology slides were analyzed. For confirmation
of the results, G.D. Searle sent the slides to Biological Research,
Ltd. where board certified pathologist, Dr. Jacqueline Mauro examined
the data. She discovered that the drug appeared to induce tumors in
the liver, testes, and thyroid of the rats. The report submitted to
G.D. Searle by Dr. Mauro was known as the MBR Report.
These statistically
significant findings were confirmed by G.D. Searle's Mathematics- Statistics
Department.
Instead of submitting
these alarming findings to the FDA, G.D. Searle contracted with another
pathologist, Dr. Donald A. Willigan.
He was given 1,000
slides to examine. The Willigan Report was more to G.D. Searle's liking
because it revealed a statistically significant increase in thyroid
and testes tumors, but not in liver tumors. Liver tumors are of much
more concern to the FDA. The Willigan Report was immediately submitted
to the FDA. G.D. Searle did not disclose the MBR Report to the FDA
until August 18, 1975, 27 months after it had been given to G.D. Searle.
At first, G.D. Searle
claimed that they did not submit the MBR Report to the FDA because
of an "oversight."
The FDA Commissioner
from 1972 to 1976, Alexander Schmidt, M.D. felt that "Superficially,
it seemed like, if there would ever be a safe kind of product, that
would be it. The idea that two naturally-occurring amino acids could
harm someone in relatively small amounts...."
In an FDA memorandum
dated September 12, 1973, Martha M. Freeman, M.D. of the FDA Division
of Metabolic and Endocrine Drug Products addressed the adequacy of
the information submitted by G.D. Searle in their petition to approve
aspartame (Freeman 1973):
" Although
it was stated that studies were also performed with diketopiperazine
[DKP] an impurity which results from acid hydrolysis of Aspartame,
no data are provided on this product."
Commenting on one
particular single dose study:
" It is not
feasible to extrapolate results of such single dose testing to the
likely condition of use of Aspartame as an artificial sweetener."
It is important
to note that Dr. Freeman pointed out the inadequacy of single-dose
tests of aspartame as early as 1973.
Matalon said, "Let
us say cigarettes were invented today, and you give 20 people two packs
a day and after six weeks, no one has cancer, would you safe that it
was safe? That's what they did with NutraSweet."
Since then, the
NutraSweet Company has flooded the scientific community with single-dose
studies.
"Chemistry
- No information is provided other than formulae for Aspartame and
its diketo-piperazine."
Pharmacology - Reference
is made to 2 year rat studies, but no data are provided on acute or
chronic toxicity."
"Clinical -
No protocols or curriculum vitae information are provided for the 10
completed clinical studies. Results are reported in narrative summary
form, and tabulations of mean average values only.
No information is
given as to the identity of the reporting labs, methodology (except
rarely), or normal values. (Reported units for several parameters cannot
be verified at this time.)
"No pharmacokinetic
data are provided on absorption, excretion, metabolism, half-life;
nor bioavailability of capsule vs. food-additive administration."
Dr. Freeman concludes:
"1. The administration
of Aspartame, as reported in these studies at high dosage levels for
prolonged periods, constitutes clinical investigational use of a new
drug substance."
"2. The information
submitted for our review is inadequate to permit a scientific evaluation
of clinical safety."
She went on to recommend
that marketing of aspartame be contingent upon proven clinical safety
of aspartame. The FDA Bureau of Foods rejected Dr. Freeman's recommendation.
(Congressional Record
1985a)
Construction of
a large aspartame manufacturing plant in Augusta, Georgia was halted.
It was thought that aspartame's uncertain regulatory future was the
main reason for the stopping of construction (Farber 1989, page 47).
In the 1973 G.D. Searle Annual Report, an executive stated that "commercial
quantities of the sweetener will be supplied from the enlarged facility
of Ajinomoto."
Ajinomoto is the
inventor and main producer of the food additive MSG.
1974
Ninety of the 113 aspartame studies which were submitted by G.D. Searle
to the FDA were conducted in the early to mid- 1970's. All of the
tests that were described by the FDA as "pivotal" were
conducted during this time. Eighty percent of these tests were conducted
by G.D. Searle or by their major contractor, Hazleton Laboratories,
Inc.
(Graves 1984, page
S5497 of Congressional Record 1985a).
Dr. J. Richard Crout,
the acting director of the FDA Bureau of Drugs stated that "The
information submitted for our review was limited to narrative clinical
summaries and tabulated mean values of laboratory studies. No protocols,
manufacturing controls information or preclinical data were provided.
Such deficiencies
in each area of required information precluded a scientific evaluation
of the clinical safety of this product...."
Dr. John Olney and
Consumer Interest attorney, James Turner, Esq. met with G.D. Searle
to discuss the results of Olney's experiments. G.D. Searle representative's
claim that Olney's data raises no health concerns.
On July 26, 1974,
just 15 months after Searle petitioned for approval, FDA commissioner
Alexander Schmidt approved aspartame use in dry foods, allowing a 30-day
period for public hearings and comment. He acted on a strong endorsement
from the Bureau of Foods, now called the Center for Food Safety and
Applied Nutrition (CFSAN).
It was not approved
for baking goods, cooking, or carbonated beverages. This approval came
despite the fact that FDA scientists found serious deficiencies in
all of the 13 tests related to genetic damage which were submitted
by G.D. Searle.
At that point, consumer
attorney Turner, author of a 1970 book about food additives, objected
to the short comment period.
Turner was joined
in his protest by a now-defunct public interest group and by Dr. John
Olney, a Washington University neuropathologist who had linked aspartame
to brain lesions in mice.
Schmidt promptly
froze the approval. In an action that was the first of its kind, he
ordered that a Public Board of Inquiry be named to look into aspartame.
Schmidt also had been alerted to conflicts between Searle research
reports and conclusions from independent animal studies that the firm's
anti-infective drug, Flagyl and its cardiovascular drug Aldactone may
cause cancer. He named a Bureau of Drugs task force to investigate.
Philip Brodsky,
the unit's since-retired lead investigator, said aspartame was included
in a broad inquiry into Searle animal studies on five drugs and the
Copper-7 intrauterine device to surprise the company. "We didn't
think they'd expect us to cover it."
The task force assailed
Searle's conduct of research on most of the products, including aspartame,
in a searing, 84-page report.
"At the heart
of the FDA's regulatory process," the report said, "is its
ability to rely upon the integrity of the basic safety data submitted
by sponsors of regulated products. Our investigation clearly demonstrates
that, in the G.D. Searle Co., we have no basis for such reliance now."
The task force charged,
for example, that the company removed tumors from live animals and
stored animal tissues in formaldehyde for so long that they deteriorated.
Instead of performing autopsies on rhesus monkeys that suffered seizures
after being fed aspartame, the company had financed a new monkey study
with a different methodology that showed no problems.
For the next seven
years, Searle's petition was tied up in reviews by the task force and
other sharply critical FDA panels.
At the task force's
request, Richard Merrill, the FDA's general counsel, demanded in a
letter that Samuel Skinner, the U.S. attorney in Chicago, open a grand
jury investigation of Searle and three of its employees.
One Searle official
named by Merrill was Robert McConnell, who had been director of Searle's
Department of Pathology and Toxicology and oversaw most of the company's
aspartame research.
McConnell's Detroit
lawyer, Gerald Wahl, said that as the inquiries heated up, his client
was suddenly awarded a $15,000 bonus and asked to take a three-year
sabbatical by director Wesley Dixon. Wahl said Dixon told McConnell
he had become a "political liability," a remark Dixon later
denied making.
McConnell received
his annual salary of more than $60,000 during the sabbatical at the
Massachusetts Institute of Technology, but he never got his job back,
and ended up suing the company, Wahl said.
"I've represented
hundreds of executives, but I've never seen anybody get the deal that
McConnell got," he said. "When you boil it all down, they
were looking for continued support from McConnell during the inquiries."
G.D. Searle's responses
to queries about the testing of their drug Flagyl, serious and unexpected
side effect from other drugs they developed, and information from Dr.
John Olney's studies started a controversy within the FDA as to the
quality and validity of G.D. Searle's test of aspartame and pharmaceuticals
(Congressional Record 1985a).
1975
In July 1975, the FDA Commissioner, Dr. Alexander Schmidt appointed a
special Task Force to look at 25 key studies for the drugs Flagyl,
Aldactone, Norpace, and the food additive aspartame. Eleven of the
pivotal studies examined involved aspartame. All of the studies whether
conducted at G.D. Searle or Hazleton Laboratories were the responsibility
of the Pathology-Toxicology Department at G.D. Searle. (Gross 1987a,
page 430 of US Senate 1987).
The special Task
Force was headed by Philip Brodsky, FDA's Lead Investigator and assisted
by FDA Toxicologist, Dr. Adrian Gross. The Task Force was especially
interested in "pivotal" tests as described in an article
from Common Cause Magazine by Florence Graves (Graves 1984, page S5499
of Congressional Record 1985a):
" Before the
task force had completed its investigation in 1976, Searle had submitted
the vast majority of the more than 100 tests it ultimately gave the
FDA in an effort to get aspartame approved.
These included all
test ever described as 'pivotal' by the FDA. About half the pivotal
tests were done at Searle; about one-third were done at Hazleton Laboratories.
'Pivotal' tests include long-term (two-year) tests such as those done
to determine whether aspartame might cause cancer.
Former FDA commissioner
Alexander Schmidt said in a recent interview that if a pivotal test
is found to be unreliable, it must be repeated 'Some studies are more
important than others, and they have to be done impeccably,' Schmidt
said."
G.D. Searle executives
admitted to "payments to employees of certain foreign governments
to obtain sales of their products." (Searle 1975)
Consumer lawyer
Turner said, "The notion that an industrial company would take
large sums of money and parcel it out to scientific consulting firms
and university departments, who they consider to be personal and commercial
allies is an unconscionable way to ensure the safety of the American
food supply."
He said the NutraSweet
experience shows that "the entire system of the way scientific
research is done needs to be carefully investigated, evaluated, and
revamped."
Food industry officials
also said most studies financed by Searle or the NutraSweet Co. have
been arranged as contracts, rather than grants. Smith said the company
often uses contracts "to accomplish a specific research task."
James Scala, former
director of health sciences for the General Foods Corp., a major NutraSweet
user, said that a scientist working under contract became "more
of an arm of the Searle research group than a grantee."
On July 10, 1975,
Senator Edward Kennedy chaired a hearing on drug-related research before
the Senate Subcommittee on Health of the Committee on Labor and Public
Welfare (US Senate 1975). Preliminary reports of discrepancies discovered
about G.D. Searle were discussed.
The findings of
the FDA Task Force were later presented at further hearings on January
20, 1976 (US Senate 1976a) and April 8, 1976 (US Senate 1976b).
Chief investigator
Brodsky said that "politicized" handling of the task force
disclosures, at hearings chaired by Sen. Edward Kennedy D-Mass., was
one reason he retired in 1977. He said the main witnesses, Searle executives,
and top FDA officials uninvolved in the investigation gave "the
wrong answers to the wrong questions"...They didn't even let the
experts answer the questions.
On December 5, 1975,
Dr. John Olney and James Turner waived their right to a hearing at
the suggestion of the FDA General Counsel after the FDA and G.D. Searle
agreed to hold a Public Board Of Inquiry (PBOI) (Federal Register 1975).
On December 5, 1975,
the FDA put a hold on the approval of aspartame due to the preliminary
findings of the FDA Task Force. The Public Board of Inquiry is also
put on hold.
The evidence of
the aspartame pivotal studies were protected under FDA seal on December
3, 1975 (Sharp 1975).
G.D. Searle had
invested 19.7 million dollars in an incomplete production facility
and 9.2. million dollars in aspartame inventory. On December 8, 1975,
stockholders filed a class action lawsuit alleging that G.D. Searle
had concealed information from the public regarding the nature and
quality of animal research at G.D. Searle in violation of the Securities
and Exchange Act (Farber 1989, page 48).
1976
On January 7, 1976, G.D. Searle submitted to the FDA their proposal for
the adoption of "Good Laboratory Practices" (Buzzard 1976b).
G.D. Searle's input was used in FDA's adoption of Good Laboratory
Practices.
In March 1976, the
FDA Task Force completed a 500-page report with 15,000 pages of exhibits
(80-page summary) to the FDA after completing their investigation (Schmidt
1976c, page 4 of US Senate 1976b).
A preliminary statement
about the breadth of the investigation from FDA Toxicologist and Task
Force team member, Dr. Andrian Gross before the US Senate (Gross 1987a,
page 1-2):
" Practices
that were noted in connection with any given such study were quite
likely to have been noted also for other studies that were audited,
and this was a situation which was in no way unexpected: after all,
the set of all such studies executed by that firm from about 1968 to
the mid- 1970's were conducted in essentially the same facilities,
by virtually the same technicians, professional workers and supervisors,
and the nature of such studies does not differ much whether a food
additive or a drug product is being tested for safety in laboratory
animals.
It is in this sense,
therefore, that the overall conclusion summarized at the beginning
of the Searle Task Force Report have relevance to all the studies audited
in 1975 (whether they had references to aspartame or to any of the
six drug products of Searle's) and, by extension, to the totality of
experimental studies carried out by that firm around that time -- 1968
to 1975."
A few of the conclusions
of the FDA Task Force (Gross 1987a, page 2-3):
" At the heart
of FDA's regulatory process is its ability to rely upon the integrity
of the basic safety data submitted by sponsors of regulated products.
Our investigation clearly demonstrates that, in the (case of the) GD
Searle Company, we have no basis for such reliance now."
" We have noted
that Searle has not submitted all the facts of experiments to FDA,
retaining unto itself the unpermitted option of filtering, interpreting,
and not submitting information which we would consider material to
the safety evaluation of the product . . . Finally, we have found instances
of irrelevant or unproductive animal research where experiments have
been poorly conceived, carelessly executed, or inaccurately analyzed
or reported."
" Some of our
findings suggest an attitude of disregard for FDA's mission of protection
of the public health by selectively reporting the results of studies
in a manner which allay the concerns of questions of an FDA reviewer."
" Unreliability
in Searle's animal research does not imply, however, that its animal
studies have provided no useful information on the safety of its products.
Poorly controlled experiments containing random errors blur the differences
between treated and control animals and increase the difficulty of
discriminating between the two populations to detect a product induced
effect.
A positive finding
of toxicity in the test animals in a poorly controlled study provides
a reasonable lower bound on the true toxicity of the substance.
The agency must
be free to conclude that the results from such a study, while admittedly
imprecise as to incidence or severity of the untoward effect, cannot
be overlooked in arriving at a decision concerning the toxic potential
of the product."
A few of the relevant
findings summarized from various documents describing the FDA Task
Force Report:
1. "Excising
masses (tumors) from live animals, in some cases without histologic
examination of the masses, in others without reporting them to the
FDA." (Schmidt 1976c, page 4 of US Senate 1976b) Searle's representatives,
when caught and questioned about these actions, stated that "these
masses were in the head and neck areas and prevented the animals from
feeding." (Buzzard 1976a)
"Failure to
report to the FDA all internal tumors present in the experimental rats,
e.g., polyps in the uterus, ovary neoplasms as well as other lesions." (Gross
1987a, page 8).
2. G.D. Searle "stored
animal tissues in formaldehyde for so long that they deteriorated." (Gordon
1987, page 496 of US Senate 1987; US Schmidt 1976c, page 25, 27 of
US Senate 1976b)
3. "Instead
of performing autopsies on rhesus monkeys that suffered seizures after
being fed aspartame, the company had financed a new monkey seizure
study with a different methodology that showed no problems." (Gordon
1987, page 496 of US Senate 1987)
4. "Reporting
animals as unavailable for necropsy when, in fact, records indicate
that the animals were available but Searle choose not to purchase them." (Schmidt
1976c, page 5 of US Senate 1976b)
5. Animals which
had died were sometimes recorded as being alive and vice versa. "These
include approximately 20 instances of animals reported as dead and
then reported as having vital signs normal again at subsequent observation
periods." (Gross 1985, page S10835)
6. "Selecting
statistical procedures which used a total number of animals as the
denominator when only a portion of the animals were examined, thus
reducing the significance of adverse effects." (Schmidt 1976c,
page 4 of US Senate 1976b)
7. G.D. Searle told
the FDA that 12 lots of DKP were manufactured and tested in one study,
yet only seven batches were actually made. (Gross 1985, page S10835)
8. "Significant
deviations from the protocols of several studies were noted which may
have compromised the value of these studies . . . In at least one study,
the Aspartame 52 weeks monkey study, the protocol was written after
the study had been initiated." (Gross 1985, page S10835)
9. "It is significant
to note that the Searle employee responsible for reviewing most of
the reproduction studies had only one year of prior experience, working
on population dynamics of cotton tail rabbits while employed by Illinois
Wildlife Service. In order to prepare him for this title of 'Senior
Research Assistant in Teratology' (fetal damage) Searle bought him
books to read on the subject and also sent him to a meeting of the
Teratology Society. This qualified him to submit 18 of the initial
tests to the FDA, in addition to training an assistant and 2 technicians.
He certainly must have kept them busy because Searle claimed that 329
teratology examinations were conducted in just 2 days. He estimated
that he himself examined about 30 fetuses a day, but officials for
the Center for Food and Applied Nutrition could never determine how
that was possible."
10. "In each
study investigated, poor practices, inaccuracies, and discrepancies
were noted in the antemortem phases which could compromise the study."
11. "Presenting
information to FDA in a manner likely to obscure problems, such as
editing the report of a consulting pathologist . . . Reporting one
pathology report while failing to submit, or make reference to another
usually more adverse pathology report on the same slide." (Schmidt
1976c, page 4-5 of US Senate 1976b)
12. Animals were
not removed from the room during the twice per month exterminator sprayings.
(Gross 1985, page S10836 of Congressional Record 1985b)
13. Often the substance
being tested which was given to the animals was not analyzed or tested
for homogeneity. "No records were found to indicate that any treatment
mixtures used in the studies were ever tested or assayed for pesticide
content . . . Running inventory records for either treatment mixtures
or the test compounds used in treatment mixtures are not maintained."
14. In the Aspartame
(DKP) 115 week rat study the written observations of the pathology
report was changed by the supervising pathologist, Dr. Rudolph Stejskal
even though he was not physically present during the autopsies and
could not have verified the observations of the pathologist who did
perform the autopsies. The pathologist who did perform some of the
autopsies had no formal training for such procedures.
15. "Contrary
to protocol, slides were not prepared of this [unusual lesions from
the Aspartame (DKP) study) tissue for microscopic examinations . .
. ."
16. "In the
Aspartame 46 weeks hamster study, blood samples reported in the submission
to FDA as 26 week values (for certain specified animals) were found
by our investigators as being, in fact, values for different animals
which were bled at the 38th week. Many of the animals for which these
values were reported (to the FDA) were dead at the 38th week." (Gross
1985, page S10838)
"It is apparent
from the report, that the Appendix portion contains all the individual
(animal) values of clinical lab data available from the raw data file.
A selected portion of these values appears to have been used in computing
group means (which were reported to the FDA). It is not clear what
criteria may have been used for selecting a portion of the data or
for deleting the others in computing the means (reported to the FDA)." (Gross
1985, page S10838 of Congressional Record 1985b)
17. "Searle
technical personnel failed to adhere to protocols, make accurate observations,
sign and date records, and accurately administer the product under
test and proper lab procedures."
18. [There were] "clerical
or arithmetic errors which resulted in reports of fewer tumors."
19. [G.D. Searle] "delayed
the reporting of alarming findings." FDA Toxicologist and Task
Force member, Dr. Andrian Gross stated:
"They [G.D.
Searle] lied and they didn't submit the real nature of their observations
because had they done that it is more than likely that a great number
of these studies would have been rejected simply for adequacy. What
Searle did, they took great pains to camouflage these shortcomings
of the study. As I say, filter and just present to the FDA what they
wished the FDA to know and they did other terrible things for instance
animals would develop tumors while they were under study. Well they
would remove these tumors from the animals."
FDA Lead Investigator
and Task Force Team Leader, Phillip Brodsky described the 1975 FDA
Task Force members as some of the most experienced drug investigators.
He went on to state that he had never seen anything as bad as G.D.
Searle's studies.
The report quoted
a letter written to G.D. Searle on July 15, 1975 from its consultant
in reproduction and teratology, Dr. Gregory Palmer, in regards to a
review of some of G.D. Searle's reproductive studies submitted to the
FDA; (as noted in the Congressional record)
" Even following
the track you did, it seems to me you have only confounded the issue
by a series of studies most of which have severe design deficiencies
or obvious lack of expertise in animal management. Because of these
twin factors, all the careful and detailed examination of fetuses,
all the writing, summarization and resummarization is of little avail
because of the shaky foundation."
G.D. Searle officials
noted that Dr. Palmer did not look at all of the teratology studies
(Searle 1976b, page 21). However, there is no credible evidence that
would lead a reasonable person to believe that the studies which were
not presented to Dr. Palmer were much better. In fact, the evidence
shows that it is very likely that all of the studies were abysmal.
The FDA Commissioner
at the time, Alexander Schmidt stated (Graves 1984, page S5497 of Congressional
Record 1985a):
" [Searle's
studies were] incredibly sloppy science. What we discovered was reprehensible."
Dr. Marvin Legator,
professor and director of environmental toxicology at the University
of Texas and the pioneer of mutagenicity testing at the FDA from 1962
to 1972 was asked by Common Cause Magazine to review the FDA investigation
results of G.D. Searle's tests page (Congressional Record 1985a):
" [All tests
were] scientifically irresponsible [and] disgraceful.
I'm just shocked
that that kind of sloppy [work] would even be sent to FDA, and that
the FDA administrators accepted it. There is no reason why these tests
couldn't have been carried out correctly. It's not that we are talking
about some great scientific breakthrough in methodology."
Senator Edward Kennedy
at the April 8, 1976 hearings before the Senate Subcommittee on Labor
and Public Welfare stated (Se. Ted Kennedy 1976):
" The extensive
nature of the almost unbelievable range of abuses discovered by the
FDA on several major Searle products is profoundly disturbing."
" In all of
the studies at Searle which have been examined by the FDA in its investigation,
the scope of the material being considered included seven years of
observation, from 1968 to date, in 57 studies involving more than 5,700
animals with over 228 million observations and calculations."
However, their deliberate
misconduct and "lies" (as put by FDA Investigator, Dr. Adrian
Gross) invalidated their experiments for the following reasons:
1. Many of the problems
with the studies included horrendous experimental designs, questions
regarding dosage given, loss of animal tissue and data, etc., etc.,
which invalidates entire experiments and causes what they claim to
be 4 million observations and calculations per study (average) to become
irrelevant.
2. Only the key
aspartame studies were looked at. It is almost a certainty that the
non-key aspartame studies were equally flawed. Therefore, this would
invalidate the "hundreds of millions" of observations and
calculations made during these studies.
3. The difference
between a study showing no statistical difference and a significant
statistical difference is often only a few observations or calculations.
Therefore, had the myriad of other serious experimental errors not
occurred (as detailed above), the observation and calculation mistakes
in each experiment investigated would, by themselves, invalidate most
of the key studies.
4. It is highly
unlikely that the FDA Investigative teams found all of the problems
with G.D. Searle's studies. G.D. Searle seemed so intent on covering
up their misconduct, that it is quite likely that they were able to
hide many of the problems from the FDA. A series of poorly conceived,
flawed studies funded by G.D. Searle were published in Volume 2 (1976)
of the Journal of Toxicology and Environmental Health. An Associate
Editor of this scientific journal was Robert G. McConnell, the Director
of G.D. Searle's Department of Pathology and Toxicology (the department
responsible for monitoring the quality of G.D. Searle's pre-approval
tests investigated by the 1975 FDA Task Force). Mr. McConnell's story
continues later in 1977.
Another G.D. Searle
employee, Carl R. Mackerer was an editor of the journal. Another editor
of the journal was Thomas R. Tephly, the person responsible for conducting
a series of badly flawed blood methanol and formate measurements in
NutraSweet-funded studies over the last 15 years.
In July 1976, the
FDA decided to investigate 15 key aspartame studies submitted by G.D.
Searle in which the 1975 FDA Task Force discovered problems. Three
(3) of the studies were investigated at the FDA (E5, E77/78, E89) by
a 5-member Task Force headed by FDA veteran Inspector, Jerome Bressler.
On August 4, 1976,
G.D. Searle representatives met with the FDA and convinced them to
allow G.D. Searle to hire a private agency, University Associated for
Education in Pathology (UAREP), and pay them $500,000 to "validate" the
other 12 studies.
According the FDA
Commissioner during the early 1980s, Arthur Hull Hayes, the UAREP investigation
was to "make sure that the studies were actually conducted."
As described by
Florence Graves:
" The pathologists
were specifically told that they were not to make a judgment about
aspartame's safety or to look at the designs of the tests. Why did
the FDA choose to have pathologists conduct an investigation when even
some FDA officials acknowledged at the time that UAREP had a limited
task which would only partially shed light on the validity of Searle's
testing? The answer is not clear.
" Dr. Kenneth
Endicott, Director of UAREP, said in an interview that the FDA had
'reasons to suspect' that Searle's tests 'were not entirely honest.'
Because the FDA 'had doubts about [Searle's] veracity,' Edicott said,
officials wanted UAREP 'to determine whether the reports were accurate.'
" FDA scientist
Dr. Adrian Gross, in a letter to an FDA official, said, 'speaking as
a pathologist, it seemed questionable that the group could do the kind
of comprehensive investigation that was required. He pointed in particular
to a variety of issues that needed to be investigated. He said some
of these would involved closely questioning administrators and lab
technicians about their practices. Since many important issues that
should be investigated 'have nothing to do with pathology,' he said,
only trained FDA investigators were qualified to do a comprehensive
evaluation of the testing. . . .
(SEE LETTER BY DR.
ADRIAN GROSS 3)
" Meanwhile,
an interview with Endicott indicates that Adrian Gross was right: the
pathologists couldn't--and didn't--carry out a comprehensive review.
. . . As former FDA Commissioner Alexander Schmidt put it in a recent
interview, UAREP looked at the slides to determine whether they had
been misrepresented, but didn't look at the conduct of the experiments
in depth. The 1975 [FDA] task force investigation looked at the conduct
of the experiments in depth, but did not look at the slides. . . .
Endicott agreed . . . 'We could only look at what was there--the tissues.'
The findings of
this investigation where released in the Bessler Report in August 1977
(see below).
1977
Our political process at work:
Donald Rumsfeld,
who was a former member of the U.S. Congress and the Chief of Staff
in the Gerald Ford Administration, was hired as G.D. Searle's President.
Attorney James Turner, Esq. alleged that G.D. Searle hired Rumsfeld
to handle the aspartame approval difficulties as a "legal problem
rather than a scientific problem." (US Senate 1987).
Rumsfeld hired:
John Robson as Executive Vice President. He was a former lawyer with
Sidley and Austin, Searle's Law Firm and also served as chairman of
the Civil Aeronautics Board, which was then connect to the Department
of Transportation.
Robert Shapiro as
General Counsel. He is now head of Searle's NutraSweet Division. He
had been Robson's Special Assistant at the Department of Transportation.
William Greener,
Jr., as Chief Spokesman. He was a former spokesman in the [Gerald]
Ford White House.
Donald Rumsfeld
is now on the Board of Directors of the Chicago Tribune which recently
wrote a glowing article about the NutraSweet Company.
On January 10, 1977,
FDA Chief Counsel Richard Merrill recommended to U.S. Attorney Sam
Skinner in a 33-page letter detailing violations of the law that a
grand jury be set up to investigate G.D. Searle. In the letter, Merrill
stated:
"We request
that your office convene a Grand Jury investigation into apparent violations
of the Federal Food, Drug, and Cosmetic Act, 21 U.S..C. 331(e), and
the False Reports to the Government Act, 18 U.S.C. 1001, by G.D. Searle
and Company and three of its responsible officers for their willful
and knowing failure to make reports to the Food and Drug Administration
required by the Act, 21 U.S.C. 355(i), and for concealing material
facts and making false statements in reports of animal studies conducted
to establish the safety of the drug Aldactone and the food additive
Aspartame."
BRESSLER:
All of the G.D.
Searle studies were abysmal as discussed earlier. However, there were
two studies where the violations of the law appeared to be especially
flagrant. The two studies cited by Merrill were the 52-week toxicity
study on infant monkeys performed by Dr. Waisman which G.D. Searle
withheld key information from the FDA and the 46-week toxicity study
of hamsters where G.D. Searle had taken blood from healthy animals
at the 26th week and claimed that the tests had actually been performed
at the 38th week.
Many of the animals
from which G.D. Searle claimed had blood drawn from were actually dead
at the 38th week. See earlier discussion for references.
On January 26, 1977,
G.D. Searle's law firm, Sidley & Austin, requested a meeting with
U.S. Attorney Samuel Skinner before a grand jury is convened. One representative
of Sidley & Austin at that meeting was Newton Minow who is currently
on the Board of Directors at the Chicago Tribune.
On March 8, 1977,
in a confidential memo to aides, while he was supposed to be pushing
for fraud indictments against G.D. Searle, U.S. Attorney Samuel Skinner
stated that he had begun preliminary employment discussions with G.D.
Searle's law firm Sidley & Austin. page 497 of US Senate 1987;
On April 13, 1977,
a U.S. Justice Department memo urged U.S. Attorney Samuel Skinner to
proceed with grand jury investigations of G.D. Searle. The memo points
out that the Statute of limitations on prosecution would run out shortly
(October 10, 1977 for the Waisman monkey study and December 8, 1977
for the hamster study.
Samual Skinner withdrew
from the G.D. Searle case and Assistant U.S. Attorney William Conlon
was then assigned to the Grand Jury investigation (Gordon 1987, page
497 of US Senate 1987).
On July 1, 1977,
U.S. Attorney Samuel Skinner left his job to work for the G.D. Searle
law firm Sidley & Austin. Thomas Sullivan was appointed as Samuel
Skinner's successor page 497 of US Senate 1987).
Meanwhile, Much
like the earlier team, the five-member FDA task force, headed by veteran
Chicago inspector Jerome Bressler, assailed the quality of animal tests
into whether the substance might cause birth defects and tumors. The
report said Searle laboratory employee Raymond Schroeder, who worked
on related research, first told investigators the feed in the study
of the aspartame breakdown product DKP (diketopiperazine) was so inadequately
mixed it appeared the rats could "discriminate" and avoid
eating the DKP. Schroeder, who has worked for another company since
1975, later backed off his statement. He told UPI, "I just didn't
feel qualified to speak on something I didn't work on...There's no
one twisting my arm."
In August 1977,
the Bressler Report pertaining to three key aspartame studies, E5,
E77/78 and E89, was released. Some of the findings from the three studies
reviewed by the Bressler- led FDA Task Force include.
1. In one study,
98 of the 196 animals died but were not autopsied until as much as
one year later. Because of the delay, much of the animal tissue could
not be used and at least 20 animals had to be excluded from postmortem
examinations.
2. The original
pathology sheets and the pathology sheets submitted to the FDA showed
differences for 30 animals.
3. One animal was
reported alive at week 88, dead from week 92 through week 104, alive
at week 108, and finally dead at week 112.
4. An outbreak of
an infectious disease was not reported to the FDA.
5. Tissue from some
animals were noted to be unavailable for analysis on the pathology
sheets, yet results from an analysis of this "unavailable" tissue
was submitted to the FDA.
6. There was evidence
that the diet mix was not homogeneous allowing the animals to eat around
the test substance. This evidence included a picture and statements
by a lab technician.
7. Fifteen fetuses
from animals in one experiment were missing.
8. Sections from
the animals were too thick for examination.
9. There was no
documentation on the age or source of the test animals.
10. There was no
protocol until one of the studies was well underway.
11. Animals were
not permanently tagged to prevent mix-ups.
12. Some laboratory
methods were changed during the study, but not documented. A G.D. Searle
pathologist referring to the DKP study was quoted by investigators
as saying:
" You should
have seen things when this study was run -- there were five studies
being run at one time -- things were a mess!"
The leader of the
Task Force, Jerome Bressler, was quoted as saying:
" The question
you have got to ask yourself is: Because of the importance of this
study, why wasn't greater care taken? The study is highly questionable
because of our findings. Why didn't Searle, with their scientists,
closely evaluate this, knowing fully well that the whole society, from
the youngest to the elderly, from the sick to the unsick . . . will
have access to this product."
Howard Roberts,
acting director of FDA's Bureau of Foods, appointed a five-person task
force to review the Bressler team's findings pending a decision on
whether to throw out the three tumor and birth-defect studies.
Jacqueline Verrett,
a senior FDA scientist on the review team, said members were barred
from stating opinions about the research quality. "It was pretty
obvious that somewhere along that line they (bureau officials) were
working up to a whitewash," she said.
"I seriously
thought of just walking off of that task force." Verrett, now
a private consultant, said that she and other members wanted to "just
come out and say that this whole experiment was a disaster and should
be disregarded."
But on September
28, 1977, the panel reported that deviations between Searle's raw data
and its FDA submissions were "not of such magnitude as to alter
its conclusion."
Verrett said the
bureau's intent seemed to be "to tone down what was really found." She
noted the bureau felt pressure because safety concerns also had been
raised about cyclamate, another alternative for the cancer-linked sugar
substitute, saccharin.
In October, 1978,
a year after ordering the review that helped get Searle's petition
back on track, Robert's (acting Director of Bureau of Foods) quit to
become vice president at the National Soft Drink Association. The NSDA's
members later marketed a stream of NutraSweet-flavored diet soft drink
products.
Reached at NSDA,
Roberts dismissed Verrett's criticism, asserting the task force report "really
was of no importance." He said he had no concerns about the appearance
of his taking the NSDA job, stressing he does not represent NSDA before
the FDA. "I sleep well at night," he said.
For each of the
major discrepancies found by the Bressler-led Task Force -- those listed
above and many others -- there was a comment in the FDA Bureau of Foods
Report minimizing the problem. It seemed that no matter how serious
the mistakes were, the FDA Bureau of Foods was determined to accept
the studies by G.D. Searle.
The experimental
errors as described above were so bad that it proved difficult to minimize
all of the major errors in these key studies.
In some cases, the
best that the CFSAN could do was to say that "The Task Force could
find no evidence that this was a deliberate attempt to influence the
study." or "It could not be determined if the results would
have been altered...."
The Senior Scientist
of the FDA Bureau of Foods Task Force, Jacqueline Verrett had left
the FDA. Speaking for the UPI Investigation into Aspartame, she said,
'I seriously thought of just walking off of that task force.' Verrett,
now a private consultant, said that she and other members wanted to
'just come out and say that this whole experiment was a disaster and
should be disregarded.'
In her testimony
before the U.S. Senate, Dr. Verrett stated the following (Verrett 1987):
" This authentication
was hence intended to verify that the submitted data had not been altered;
that it reflected the actual outcome of the study, and that it did
not change substantially, particularly in a statistical sense, the
various parameters from which the conclusion of safety had been derived.
" Our analysis
of the data in this manner revealed that in these three studies, there
were really no substantial changes that resulted, although in numerous
instances, a definitive answer could not be arrived at because of the
basic inadequacies and improper procedures used in the execution of
these studies.
" I would like
to emphasize the point that we were specifically instructed not to
be concerned with, or to comment upon, the overall validity of the
study. This was to be done in a subsequent review, carried out at a
higher level. . . . . "It would appear that the safety of aspartame
and its breakdown products has still not been satisfactorily determined,
since many of the flaws cited in these three studies were also present
in all of the other studies submitted by Searle. . . . .
" Well, they
told us in no uncertain terms that we were not to comment on the validity
of it. And I hoped, although having been there at that point for 19
years, I should have known better, that there really would be an objective
evaluation of this beyond the evaluation that we did.
" I do not
feel that that was done, based on what I have read in the GAO report
that I have looked at and so forth. They definitely did not objectively
evaluate these studies, and I really think it should have been thrown
out from day one.
" We were looking
at a lot of little details and easy parameters in this study, when
the foundation of the study, the diet and all of these other things,
were worthless. We were talking about the jockey when we should have
been talking about the horse, that he had weak legs. It is built on
a foundation of sand."
The FDA general
counsel wrote a letter to Consumer Attorney, James Turner, Esq. responding
to Mr. Turner's concern about the quality and validity of G.D. Searle's
experiments. The FDA stated, "The Public Board of Inquiry on aspartame
should provide a vehicle for definitive resolution, at least for those
studies about which you are most concerned.
As will be discussed
later, Dr. John Olney and James Turner, Esq. were not allowed to have
the quality and validity of the G.D. Searle studies considered at the
Public Board of Inquiry.
1978
On December 13, 1978, UAREP submitted its results of their analysis of
12 of G.D. Searle's aspartame studies. UAREP stated in their report
that "no discrepancies in any of the sponsor's reports that
were of sufficient magnitude or nature that would compromise that
data originally submitted." (Farber 1989, page 33) Remember,
the Director of UAREP pointed out in an interview that their pathologists
did not conduct a comprehensive review of the studies, they only
looked at the animal tissues.
As it turns out,
UAREP pathologists who examined the test results were discovered to
have missed and withheld negative findings from the FDA. In some cases,
they completely missed cancerous brain tumors when analyzing the slides.
In addition, some of the slides that were to be examined by UAREP pathologists
were missing even though they where supposed to have been kept under "FDA
seal." (Olney 1987, page 6-7)
FDA Toxicologist
Adrian Gross stated that the UAREP review "may well be interpreted
as nothing short of a whitewash." (Farber 1989, page 114). Given
that the UAREP review results was so biased in favor of G.D. Searle,
one wonders why the FDA would allow a company being investigated for
fraud to pay $500,000 and hire an outside entity to "validate" their
studies.
Even though the
UAREP report was biased, there were numerous instances in that report
which demonstrated that G.D. Searle had not submitted even marginally
accurate findings to the FDA of their pre-approval aspartame tests.
For example, in one study, twelve animals actually had cancerous brain
tumors, yet UAREP reported to the FDA that only three animals had such
tumors.
1979
In March of 1979, the FDA somehow concluded that G.D. Searle's aspartame
studies could be accepted. They decide to convene the Public Board
of Inquiry (PBOI) which was agreed to by Dr. John Olney and Attorney
James Turner more than four years earlier (Federal Register 1979).
In April of 1979,
the FDA outlined the specific questions which were to be addressed
by the PBOI. The FDA limited the scope of the PBOI to (Federal Register
1981):
1. Whether the ingestion
of aspartame either alone or together with glutamate poses a risk of
contributing to mental retardation, brain damage, or undesirable effects
on neuroendocrine regulatory systems.
2. Whether the ingestion
of aspartame may induce brain neoplasms (tumors) in the rat.
3. Based on answer
to the above questions.
(i) Should aspartame
be allowed for use in foods, or, instead should approval of aspartame
be withdrawn?
(ii) If aspartame
is allowed for use in foods, i.e., if its approval is not withdrawn,
what conditions of use and labeling and label statements should be
required, if any?
Dr. John Olney,
G.D. Searle, and the FDA's Bureau of Foods were allowed to nominate
scientists for the 3-person PBOI panel (Farber 1989, page 34, Federal
Register 1981, page 38286).
It is important
to note that the scope of the review was very limited in light of all
of the various adverse reactions reported to the FDA. The PBOI also
disallowed any discussion of the validity of the pre-approval experiments
because it accepted the word of certain FDA officials that these experiments
had been "validated." Finally, the PBOI was told not to consider
aspartame in beverages, only in dry goods.
In June of 1979,
the acting FDA Commissioner, Sherwin Gardner selected the 3-person
Public Board of Inquiry. The panelists were Peter J. Lampert, M.D.,
Professor and Chairman, Department of Pathology, University of California
(San Diego), Vernon R. Young, Ph.D., University of Nutritional Biochemistry,
M.I.T., and Walle Nauta, M.D., Ph.D., Institute Professor, Department
of Psychology and Brain Science, M.I.T.
Dr. John Olney strongly
objected to the Commissioner's selection of one of the panelists, Dr.
Vernon Young, on grounds of conflict of interest and lack of qualifications
(Olney 1987, page 3). Dr. Young had written nonaspartame- related articles
in collaboration with G.D. Searle scientists (Brannigan 1983, page
196).
In addition, Dr.
Olney stated that the question of aspartic acid's neurotoxicity should
be looked at by a neuropathologist and that Dr. Young was unqualified
since his field was Nutrition and Metabolism. Dr. Olney's objections
were overruled by acting FDA Commissioner Sherwin Gardner and the panelists
who he objected to was assigned to study the issue of aspartic acid
toxicity.
One of the PBOI
members, Dr. Walle Nauta stated (Graves 1984, page S5498 of Congressional
Record 1985a):
" It was a
shocking story we were told [about Searle's animal testing] but, there
was no way we could go after it. We had absolutely no way of knowing
who was right. We had to take the FDA's word."
Dr. Nauta stated
that he would have "definately" considered other tests and
factors if he had known that aspartame was planned for use in soft
drinks (Graves 1984, page S5503 of Congressional Record 1985a).
1980
The Public Board Of Inquiry voted unanimously to reject the use of aspartame
until additional studies on aspartame's potential to cause brain
tumors could be done. The PBOI was particularly concerned about experiment
E33/34 where 320 rats received aspartame and a much higher percentage
of animals in the aspartame group developed tumors than in the control
group (Brannigan 1983, page 196).
In addition, the
PBOI was concerned about experiment E70 where 80 rats received aspartame.
Both the aspartame group and the control group had an unusually high
number of tumors, leading one to suspect that both groups were actually
given aspartame (Federal Register 1981).
The PBOI did not
believe that aspartic acid presented a neurotoxic hazard. Yet, Dr.
Olney pointed out that (Olney 1987, page 3):
" [Dr. Young
had a] lack of qualification" and that he "based his decision
on a consideration of [aspartic acid] alone without regard to the real
issue, i.e., is it safe to add [aspartic acid] to the large amounts
of [glutamic acid/MSG] that are already adulterating the food supply?"
In addition, the "conservative" safety
plasma level of aspartic acid used by Dr. Young was the level at which
half the animals developed brain damage (Brannigan 1983, page 197).
These errors by
Dr. Young throw the question of safety of aspartic acid as part of
aspartame into doubt. We will address this issue in more detail in
a later section.
1981
On January 21, 1981, the day after Ronald Reagan takes office as U.S.
President, G.D. Searle reapplied for the approval of aspartame. G.D.
Searle submits several new studies along with their application.
It was believed that Reagan would certainly replace Jere Goyan, the
FDA Commissioner.
G.D. Searle president,
Donald Rumsfeld's connections to the Republican party were also thought
to play a part in Searle's decision to reapply for aspartame's approval
on the day after Ronald Reagan was inaugurated (Gordon 1987, page 499
of US Senate 1987).
According to a former
G.D. Searle salesperson, Patty Wood- Allott, G.D. Searle president,
Donald Rumsfeld told his sales force that, if necessary, "he would
call in all his markers and that no matter what, he would see to it
that aspartame would be approved that year." (Gordon 1987, page
499 of US Senate 1987)
Robert Dormer, a
lawyer for the NutraSweet Co., said there was nothing special about
the Jan. 21 date or the papers filed that day.
But with Reagan's
election, it was virtually assured that a republican-appointed commissioner
would replace Goyan and decide the appeal- and Searle had strong GOP
connections with Rumsfeld at the helm.
Goyan had set up
a five-member "commissioner's team" of scientists with no
prior involvement in the issue to review the board's ruling.
In April 1981, Arthur
Hull Hayes, Jr. was appointed FDA Commissioner by Ronald Reagan (Graves
1984, page S5502 of Congressional Record 1985a).
On May 18, 1981,
three of the scientists in the 5-member panel sent a letter to the
panel lawyer, Joseph Levitt discussing their concerns about aspartame.
Those three scientists
were Satva Dubey (FDA Chief of Statistical Evaluation Branch), Douglas
Park (Staff Science Advisor), and Robert Condon (Veterinary Medicine).
Dubey thought that the brain tumor data was so "worrisome" in
one study that he could not recommend approval of aspartame (Gordon
1987, page 495 of US Senate 1987).
In another study,
Dubey said that key data appeared to have been altered Gordon 1987,
page 499 of US Senate 1987).
In his UPI Investigation,
Gregory Gordon went on to describe the unusual events that followed
(Gordon 1987, page 499 of US Senate 1987):
" [Douglas]
Park said that panel lawyer Joseph Levitt hurried the panel to decide
the issue. 'They wanted to have the results yesterday,' he said. 'We
really didn't have the time to do the in- depth review we wanted to
do.'
" Park said
Levitt met frequently with Hayes and 'was obviously getting the pressure
to get a resolution and a decision made.'
" With three
of five scientists on the commissioner's team opposing approval, it
was decided to bring in a toxicologist for his opinion on isolated
issues [Barry N. Rosloff]. Goyan said if the decision were his, he
never would have enlarged the team.
While the panel
did not vote, it ended up split 3-3.
" Levitt, who
normally would have been expected to draft an options paper spelling
out scientific evidence on key issues, took an unusual tack. He circulated
an approval recommendation and only backed off when Dubey, Park, and
Condon objected, team members said. Levitt said he was not directed
to draft the approval memo, but did so as a 'tactical' step to break
the team's weeks-long impasse by forcing each scientist to state his
views. 'It worked, didn't it?' said Levitt, who later was promoted
to a post as an executive assistant to the FDA Commissioner."
On July 18, 1981
aspartame was approved for use dry foods by FDA Commissioner Arthur
Hull Hayes, Jr. overruling the Public Board of Inquiry and ignoring
the law, Section 409(c)(3) of the Food Drug and Cosmetic Act (21 U.S.C.
348), which says that a food additive should not be approved if tests
are inconclusive.
In an article in
Common Cause Magazine, Florence Graves states that two FDA officials
said that Arthur Hull Hayes, Jr. wanted to push aspartame approval
through in order to signal reforms of the Reagan Administration.
One team member
said that during discussions, Hayes, appeared to be abandoning the
agency's traditional standard of "reasonable" proof of safety
and looking for "proof of hazard."
Hayes' July 1981
approval decision came in the face of a Searle threat to file a suit
challenging the regulatory delays.
His ruling relied
in part on a late rat study of brain tumors submitted by Ajinmoto,
a Japanese company that manufactures aspartame for Searle. That study,
however, tested Wistar rats, a strain that some scientists said is
more tumor resistant than the Sprague-Dawley rats used in earlier research.
In his decision,
Hayes wrote: "Few compounds have withstood such detailed testing
and the repeated close scrutiny and the process through which aspartame
has gone should provide the public with confidence of its safety."
Between 1979 and
1982, four more FDA officials who participated in the approval process
took jobs linked to the NutraSweet industry: Stuart Pape was the Health
and Human Services (HHS) Chief Counsel for Foods; acting FDA commissioner
Sherwin Gardner;
Albert Kolbye, who
was associate director of the Bureau of Foods for toxicology, and Mike
Taylor, an FDA lawyer who represented the bureau before the Board of
Inquiry. All four denied any conflict of interest. (Mike Taylor: Deminimus
Legislation):
1. Mike Taylor was
an FDA lawyer who represented the FDA Bureau of Foods at the PBOI and
was part of the team that prevented the quality and validity of G.D.
Searle's studies from being considered.
2. Sherwin Gardner
was the Deputy FDA Commissioner in 1979. In July, 1974, he had signed
the initial approval for aspartame's use in dry foods. (This initial
approval was later block by objections from James Turner, Esq. and
Dr. John Olney.)
In December, 1979,
Sherwin Gardner became a Vice President of Grocery Manufacturers of
America, Inc. (GAO 1986). While Mr. Garden claims that he did not discuss
aspartame is his 4 meetings with the FDA within a year of leaving that
agency or his 20 meetings with the FDA between 1980 and 1986, the organization
he worked for does deal directly with aspartame products. It is unlikely
that he would have been rewarded with the job had he called for another
delay in approval and proposed that safety tests be conducted independently
in order to protect the public.
3. Stuart Pape was
the Health and Human Services (HHS) Chief Counsel for Foods from October
1976 to March 1979. He served as special assistant to the FDA Commissioner
from March 1979 to December 1979.
He participated
in meetings and discussions on aspartame as well as representing the
FDA at the PBOI.
In December 1979,
Mr. Pape was given a job by the law firm of Patton, Boggs, and Blow.
This law firm provided counsel to the National Soft Drink Association
(NSDA).
Mr. Pape and Howard
R. Roberts of the NSDA (who formerly fought for approval of aspartame
at the FDA) met with the FDA twice in 1983 where aspartame was discussed.
In 1983, the NSDA inexplicably withdrew their objection to aspartame
in diet beverage (GAO 1986).
4. Albert Kolbye
was the Associate Director of the FDA Bureau of Foods for toxicology.1983
In late 1982, Searle
petitioned for FDA approval to use the sweetener in diet soft drinks
and children's vitamins. On a day when Hayes was away, Novitch approved
the petition, increasing the acceptable daily intake level for humans
by nearly half, from 34 mg to 50 mg per kilogram of body weight.
Novitch, now in
private industry, said he and Hayes had worked together on the matter,
but declined to say why he was left to sign the approval.
Just weeks later,
Hayes resigned under the cloud of an internal Dept. of Health and Human
Services investigation into his acceptance of gratuities from FDA-regulated
companies - including free rides aboard jets owned by a major NutraSweet
user, the General Foods Corp.
Shortly after being
named Dean of the New York Medical school, Hayes also became a consultant
to the New York-based public relations firm of Burson-Marsteller, which
represents the NutraSweet Co. and several major users.
Hayes' former top
spokesman, Wayne Pines, who previously had joined the firm, said he
approached Hayes because he thought him "an added value" to
clients.
Hayes, now president
of the E.M. Pharmaceutical Co. in Hawthorne, N.Y., declined comment
for this series of articles. He has in the past denied any impropriety
in his consulting role, which sources said paid him more than $1000.
per day.
Burson-Marsteller
vice president, Buck Buchwald stressed that Hayes was not involved
in NutraSweet issues and worked but 10 to 15 days a year.
But a former Burson-Marsteller
employee, who requested anonymity, said Hayes was hired precisely because
of his decision on NutraSweet and other issues affecting company clients.
Sen. Metzenbaum
said it was "at the very least...unbecoming, at the very most,
it probably was inappropriate" for Hayes to accept the position.
In July 1986, Anthony
Brunetti, a FDA consumer product officer who drafted the 1983 notice
approving NutraSweet use in soft drinks, also took an industry job,
joining the soft drink association as a science advisor. Brunetti said
he cleared the move with the FDA's ethics officer.
"My situation," he
said, "is no different than many, many people...that go through
the revolving door. It can be made to look like there is some duplicity
going on. In terms of my own conscious, I have no problem."
Ron Lorentzen, an
FDA toxicologist who was asked by current Bureau of Foods chief Sanford
Miller to perform a separate, internal review of the agency's handling
of aspartame, described it as a "tortured" story.
But despite the
myriad questions and revolving door issues, he asserted the FDA responded
to each issue "in a way, perfectly reasonable."
Other questions
have arisen over the company and industry's funding of researchers
who have invariably supported NutraSweet's safety - with the exception
of people with the rare disease phenylketonuria. Independent studies
have often raised health concerns.
Dr. Lewis Stegink,
a pediatrics professor at the University of Iowa who repeatedly has
produced studies, that he says, support aspa
