A summary of the meeting follows,
beginning with a digest of LDA presentations:
Patricia Smith, President, Lyme Disease Association
Most patients with adverse
events are not reported to VAERS by physicians. I attend many events all over
the Northeast, and the vaccine and associated problems are always brought up to
me, unsolicited on my part. Last week I was at a large sportsmen's show. Just at
this show alone, I heard about seven individuals who received the vaccine and
experienced problems. One man had joint pains all over his body and his doctor
did not think it related to the vaccine, nor did he report it. The man had cut
down on hunting and fishing. He had stopped running.
When this individual went
back to his physician and asked him to report the adverse response to VAERS, the
doctor blew him off. The doctors are very much in the dark about this vaccine.
We have doctors who do not understand that boosters are required. One man came
up to me at the event and told me his doctor said no booster was required and he
thought he was fully protected forever. Many physicians do not know the vaccine
is contraindicated with a history of arthritis. Most people I spoke with who
report side effects mentioned they occurred after the second shot. An employee
at Rutgers approached me and said the University gave Lymerix. The professor
knows four Lymerix recipients at Rutgers who are having significant trouble.
I hear the same thing from
other groups. There are a lot of problems I do not think you are aware of. I
hear from physicians that the vaccine causes Lyme disease to be retriggered. I'm
out there a lot. I have no stake other than to keep people from getting Lyme
disease.
Our organization has always had
questions about the vaccine, and at the last FDA meeting in January 2001 we
requested a moratorium.
Andrea Gaito, MD, President, International Lyme & Associated Disease Society,
ILADS:
I have 35 patients with
problems stemming from the vaccine. There are three categories of problem.
The first category includes
arthritis-like presentations. These patients have symptoms that present,
clinically, like rheumatoid arthritis. They seem to have an autoimmune reaction
stemming from the presence of a genetic marker theorized to be a source of
trouble, HLA-DR4. Some of these patients may have other relevant HLAs. Perhaps
there are a cascade of other immunological reactions, including cytokines.
What I have found is that
people with Lyme who become asymptomatic may, upon vaccination with Lymerix,
experience a retriggering of symptoms. Those who never had symptoms of Lyme
disease, meanwhile, will, upon vaccination, experience the symptoms of Lyme
disease.
One example is a 55 year-old
woman with no history of Lyme disease. She presented with acute synovitis and in
her hands, wrists, ankles, and feet. The physician who administered the vaccine
told her there was no relationship between these symptoms and the vaccine. He
did not report them. It is possible that, like so many other physicians, he did
not want to trouble with the paperwork. When the woman thereafter came to me, I
ran tests. Her rheumatoid factor was negative but her Western Blot was
suggestive of active Lyme disease, with eight IgM and three IgG bands. I
prescribed for her a course of doxycycline, but she had minimal response. So I
put her on anti-inflammatory medication. Now, two years later, she is still
on anti-inflammatory medication.
The scenario for this woman
is that of an autoimmune disease.
Even though she reacted to
the vaccine in this adverse fashion, her physician made her feel guilty. Many
patients have complaints but doctors are not receptive to them. The bottom line
is that the doctor is afraid of being sued.
The second case I would like
to present involves a 20-year-old white male with a history of Lyme meningitis.
Previously, he had 4 weeks of intravenous Rocephin and before receiving Lymerix
was asymptomatic. After receiving Lymerix, however, he had the onset of
Obsessive Compulsive Disorder, headache, and fatigue. He had to leave college.
Upon testing, he had a positive ELISA and a Western Blot with every band
positive. We retreated him with another course of IV Rocephin, but he has
remained sick.
The third case involves a
48-year-old woman and gardener. She received three shots of Lymerix and then,
subsequently, was bitten by a tick. She had presumed she was one hundred percent
protected, but she went on to develop symptoms of Lyme disease, including night
sweats and fatigue. We performed a Western Blot test for this woman and found
every band to be positive. She received two course of antibiotic therapy and had
no response. She also tested positive for the HLA markers that have been
associated with Lyme-related autoimmune disease. This patient now has Lyme
disease but does not respond to treatment.
As I review my experience
with Lymerix, I find the issues to be confusing. How can we get a handle on the
efficacy of this vaccine? What about the efficacy of booster shots? Will
vaccinated individuals with prior Lyme who ultimately present with symptoms
respond to retreatment? Is the vaccine itself retriggering an autoimmune
response?
One final word: It is possible that
the difference between the pre- and post-marketing results of Lymerix relates to
the fact that those using it post-marketing lived in endemic areas for Lyme
disease.
Donald H. Marks, MD, PhD, former lab director for Cannaugh:
First let me describe my
background. I have fourteen years of clinical research and regulatory affairs
experience in the pharmaceutical industry. My positions have included Associate
Director of Clinical Research, Hoffman-LaRoche Pharmaceuticals, where I worked
on Lyme disease; Vice President of Medical Afffairs, Immunomedics; and finally,
Director of Clinical Research, Aventis Pasteur, where I was in charge of the
Lyme disease vaccine program.
The focus of my medical
practice today is on diagnosis of adverse events from medications, vaccines,
biologicals, and medical devices. Among the issues I have worked on are the
associations between Accutane and seizures, psychosis and suicide; Ephedra and
hemorrhagic stroke; Fen-Phen and heart valve problems; Lotrenex and ischemic
bowel disease; Posicor and Propulsid and arrhythmias, in the case of the former
medicine, fatal arrhythmias; Quinolone antibiotics like Floxin and Trovan and
tendon neuropathy, seizures, and hypoglycemia; Rezulin and liver toxicity and
cardiomyopathy; SSRI antidepressants like Prozac, Zoloft and Paxil and suicide,
psychosis, and seizures; and Lymerix and rheumatologic and neurologic
complications.
Today I am here as a consultant of
the Lyme Disease Association, which has asked me to review a series of adverse
events associated with Lymerix: These include athralgias and arthritis as well
as complicated neurological problems. They include adverse events that are
long-lasting.
Dr. Marks proceeded to
present a series of slides. We reproduce them here, with explanation and some
editing, where needed, for clarity and brevity in the current context.
WHY MORE ADVERSE EVENTS WERE SEEN AFTER THE VACCINE REACHED THE MARKET:
- People receiving Lymerix
after product launch were at greater risk for adverse events because they
lived in Lyme-endemic areas.
- Many of these people may
have had prior exposure and clinical or subclinical infection. In these cases,
Lymerix could be triggering or reactivating the damage caused by old and
presumably cured Lyme disease.
- Pattern of symptoms experienced
after Lymerix mimicked pattern of prior infections in many individuals. In
these patients, Lymerix-related symptoms seemed to respond to antibiotics, as
did the initial infection, bolstering the theory of disease reactivation.
HOW SMITHKLINE BEECHAM (GLAXO SMITHKLINE) USED CONFUSING LANGUAGE, KEEPING FDA
AND PHYSICIANS IN THE DARK:
- The Company dismissed the
significance of adverse events reported since marketing by stating the
vaccine's profile had not changed "except as described below…" The description
referred to, rendered with numbers but given no contextual explanation, in
fact implied a huge change in safety. The company's confusing language made it
sound as if the adverse events, many of them severe, had no particular
significance at all.
- As proof of safety, the
company inoculated arthritis-prone mice with Osp-A. But since the mice did not
possess the HLA marker known to interact with Osp-A in humans, the experiment
was, in fact, meaningless.
- The company has masked
serious causally-related adverse events behind qualifiers, such as "...and
which may have no causal relationship with the vaccine" and "...cannot be
distinguished from the natural history of the underlying disease," all the
while knowing these are confusing the issues.
- The company tries to shift
the blame from the vaccine to the patient with statements such as "the
possibility of a severe rheumatologic, neurologic, autoimmune adverse event is
inherent in Lyme disease." The company does not inform physicians that the
adverse events can result from Lymerix, completely apart from the disease.
- As a result of these actions,
GPs in the US were kept in the dark about the life-threatening side effects of
Lymerix.
SOME BASIC PROBLEMS.
- Non-specific
hyper-activation of the immune system, often evidenced through swollen hands
or arthritis, is an adverse event associated with Lymerix. This may be due to
the presence of adjuvant.
- This hyper-activation
creates "dirty" Western blots in which multiple Lyme disease bands appear,
whether the individual has Lyme disease or not.
- The dirty banding makes it
impossible for physicians to differentiate between Lymerix vaccination, new
infection with Borrelia burgdorferi, or reactivation of infection.
- The net result is that
cases of Lyme disease will go undiagnosed and untreated.
- Adverse reactions to
Lymerix will be misdiagnosed with Lyme disease and people will be
unnecessarily treated with antibiotics.
- The vaccine manufacture
provides no warnings as to these possibilities.
- Physicians unaware of the
spectrum of problems cannot appropriately treat these patients.
- The intention of FDA regulations
is to provide a vaccine that is safe and effective. The intention of
prescribing regulations is to provide sufficient information to prescribing
physicians to enable safe and effective use of the vaccine. In both regards,
SKB's actions appear to be contrary to FDA regulations and intentions, and
contrary to accepted standards within the vaccine industry.
Dr. Marks provided some case
assessments based on stringent parameters. His conclusions were based on pre-
and post-marketing as well as supplemental data; internal company documents;
published literature; international meetings; special reports; patient medical
files; and patient examinations. He used the standard methodological rule of
"more likely than not" as well as objective, scientific criteria and objective
procedures. The assessments themselves, according to Dr. Marks, were arrived at
based on "clinical presentation, the medical records, telephone interviews
and/or physical exams, temporal relatedness of the event to the vaccination,
known adverse event profile of Lymerix, mechanism of action of Lymerix, opinions
of the treating physician, articles from the medical literature on adverse
events occurring as a result of vaccination with OspA-based vaccines for Lyme
disease, my experience as a pharmaceutical industry medical safety officer, my
experience having reviewed hundreds of clinical cases of potential medication
adverse events, my experience as a vaccinologist and clinical researcher
developing vaccines and antibiotic treatments against Lyme and other diseases,
and my examination of alternative explanations." Added Marks: "The adverse
events I have examine from Lymerix ARE SIMILAR TO THOSE I AM FAMILIAR WITH FROM
ANOTHER OSPA VACCINE."
Marks examined 22 cases in
all. In each of these cases, he said, the adverse event was not anecdotal but
was, instead, a medical certaintly:
- 4 of 4 neurological
adverse events were related to Lymerix with presentations including transverse
myelitis, inflammatory polyneuropathy, radiculopathy and cervical throacic
myelopathy with multiple neurologic including CNS symptoms, and memory loss
and difficulty concentrating with immune-related complex of joint pain and
fatigue.
- 15 of 17 rheumatologic
adverse events were related, including inflammatory seronegative
spondyloarthropathy, polyarthropathy, arthralgias, and arthritis.
- 2 of 2 miscellaneous reports
were unrelated. These included chest pain and myofacial pain.
Based on his research, Marks
told FDA officials, "SKB (Glaxo) has acted in an unreasonable manner by
marketing Lymerix without adequate warnings about the risks of severe
rheumatologic, neurologic, autoimmune and other adverse events, and by failing
to caution and educate physicians about these dangers. In view of the evidence
of a strong and likely causal relationship between Lymerix and severe
rheumatologic, neurologic, autoimmune and other adverse events, SKB should
market this vaccine, if at all, with prominent warnings and cautionary
statement."
"In my opinion, SKB should
have devised and conducted clinical trials, epidemiological studies, or
after-the-fact investigations to study the causal relationship between severe
rheumatologic, neurologic, autoimmune and other adverse events and the use of
Lymerix."
Given that Dr. Marks lead the
clinical trials for Lymerix's competitor, the OspA vaccine produced and then
abandoned by Aventis Pasteur, his conclusions mean a lot. "In my opinion," he
told FDA officials, "there is sufficient evidence that Lymerix is causally
related to severe rheumatologic, neurologic, autoimmune, and other adverse
events in some individuals. This evidence is such as to warrant a significantly
heightened degree of warnings and possible limitations or removal from marketing
of Lymerix."
The floor was then handed
over to FDA to answer the following questions:
- What does the FDA intend
to do about the lyme vaccine?
- Questions on the follow-up
study of VAERS reports, especially, what is the primary endpoint and study
design for the on-going telephone survey of a subset of individuals who have
reported adverse reactions to VAERS. Specifically, what is the
inclusion/exclusion criteria? Subquestions include:
A. Assuming an inclusion
criteria includes arthritis and/or arthralgia, which VAERS codes and/or
keywords are used to identify such individuals? And, if the inclusion
criteria consists of a specific injury and/or disease process, why has the
study been so limited instead of addressing the various adverse reactions
being reported to VAERS, including non-specific pain syndromes and
development of Lyme disease-like symptoms, possibly constituting
exacerbation of previously asymptomatic Lyme disease and neurological
conditions such as Bells' Palsy, optic neuritis, and acute transverse
myelitis?
B. Further, what is the
FDA's case definition of "definite, probable and possible arthritis" for
purposes of this study? The abstract of the "preliminary evaluation" reports
completed interviews of 49 patients out of 85 attempted (out of 415 patients
with VAERS reports of "arthralgia or possible arthritis following Lyme
vaccine") reports 17 cases of "possible arthritis" and 14 cases of
"physician-diagnosed definite arthritis"). Does this mean that the remaining
18 had "probable arthritis"and, if so, what if anything is being done to
evaluate their cases?
C. How is the FDA dealing
with individuals who test positive for Lyme disease after vaccination in
terms of distinguishing between a new infection (i.e. vaccine failure) and
the exacerbation of a previously asymptomatic or presumably "cured"
infection (i.e. an adverse reaction)? It appears from the abstract that 7 of
14 cases of physician-diagnosed arthritis also had what is described as "concominant
exposure or another medical condition, including Lyme disease". What, if
anything is the FDA doing to evaluate these individuals, especially in light
of the fact that many people who have and who will receive LYMErix reside in
Lyme-endemic areas and can presumably be easily dismissed as having "concominant
exposure"?
D. Does the fact that 50%
(7 of 14) of cases of physician-diagnosed definite arthritis post
vaccination demonstrate the need for a warning and/or contraindication
against the vaccination of individuals with "familial history of
immune-mediated disease or inflammatory arthritis", "immune-mediated
disease", and "prior history of physician-diagnosed Lyme disease"?
E. When does the FDA
contemplate completion of the interviews of the 415 VAERS reports identified
as "arthralgia or possible arthritis"? And what if anything is being done to
identify such reports filed subsequent to October 2000?
F. Given the fact that
FDA has now documented 7 case reports of physician-diagnosed definite
arthritis which "could not be plausibly explained by concominant exposure,
prior diseases, or familial histories" a number on par with those that
triggered regulatory intervention in other pharmaceuticals such as "Fen-Phen",
is the FDA prepared to call for an immediate moratorium and/or withdrawal of
LYMErix and, if not, what is the threshold number of case reports needed to
trigger such action? It should be noted that 14 cases of physician-diagnosed
arthritis post vaccination were identified out of 31 patients whose medical
records were reviewed (45.2%), and in 7 of those (22.6%) the arthritis could
not plausibly be attributed to any other cause. If these rates hold for the
remainder of the 415 VAERS reports identified, the FDA will have documented
187 cases of physician-diagnosed arthritis, nearly 93 of which will not have
any other plausible explanation.
G. In terms of determining the
rate of adverse reactions, how can the FDA determine how many individuals
have been vaccinated? The abstract of the preliminary follow-up study
reports "approximately 1.4 million vaccine doses were distributed" between
December 1998 and October 2000. Given the fact that this is a multiple-dose
vaccination and that most vaccinees have received at least two or three (and
sometimes actually more) doses of LYMErix, and the fact that the uptake of
LYMErix has been unexpectedly low (as demonstrated by the difficulty in
reaching even 25% of the enrollment goals for the Phase IV studies), can the
FDA rule out the possibilities that the actual number of vaccinees is in the
low six-figures, and possibly as low as 100,000?
- How is the FDA dealing
with individuals who participated in the clinical trials, but began
experiencing adverse reactions (or recognized such reactions) only after the
study site was closed? Since VAERS will not accept their reports, and it has
been reported that GlaxoSmithKline has been dismissive of such reports, how
can the FDA ensure that these reactions are included in the total number of
adverse event reports?
- More specifically, how
does the FDA deal with study participants who were in the placebo group during
the trial (with no adverse reactions) but who received the vaccine after the
study was unblinded and went on to experience adverse reactions to the actual
vaccine?
- If an individual gets the
vaccine and they show Lyme disease symptoms, how does the FDA distinguish
between 1.someone who had asymptomatic Lyme disease, 2. a new case of Lyme
(vaccine failure), 3. an immune response
- Why has the FDA not
contacted and interviewed physicians who oversaw the study sites for the
clinical trials, particularly in light of the fact that some such doctors,
..., have publicly endorsed LYMErix stating that they saw no adverse reactions
when the FDA is aware of reports of adverse reactions by several of ...'s
study participants?
- What steps if any has the
FDA taken to analyze the data gathered during the clinical trials of the
Connaught (now Aventis Pastuer) OspA-based Lyme disease vaccine ImmuLyme for
adverse reactions?
- Why has the FDA failed to
invite scientists and physicians not affiliated with, or employed by
GlaxoSmithKline, such as Ronald Schell, Ph.D. who has published an article
documenting serious adverse reactions to OspA in hamsters, and Carlos Rose,
M.D. and Paul Fawcett, Ph.D., who have published an article documenting
arthritogenic reactions to LYMErix in adults and the exacerbation of
pre-existing asymptomatic Lyme disease in participants in the pediatric trials
of LYMErix, to present their findings and opinions to the Advisory Committee
or any other body considering the safety and efficacy of LYMErix?
- Why was LYMErix permitted
to include an adjuvant, especially given that the manufacturer used a
lipidated version of the OspA protein? Further, since the inclusion of the
adjuvant in LYMErix necessitated the inclusion of the adjuvant in the placebo,
what if anything was done to adjust for the likelihood that complaints of
adverse reactions to the adjuvant among the placebo group were not permitted
to improperly "cancel out" adverse reactions to OspA among the vaccinees, and
therefore reduce the likelihood of finding a "statistically significant
difference" in adverse event rates between the two groups?
- What if any steps has the
FDA taken to implement the recommendations of members of its Advisory
Committee from the January 31, 2001 meeting regarding enhanced warnings and
limits on the indicated use of LYMErix (including geographic limits) as well
as increased education of both the general public and the medical community of
the continued unanswered safety risks associated with LYMErix?
- Is the FDA, and/or its
Vaccine Advisory Committee aware that the Tufts Laboratory run by Dr. Steere,
the principal investigator for the Phase III clinical trials of LYMErix, filed
for a patent on March 21, 2000 with the World International Property
Organization, which received an International Publication Date of September
27, 2001 (patent # WO 01/70252 A1), and that the official patent holders,
including Doctors Meyer, Huber and Gross are the scientists who worked along
with Dr. Steere on his research documenting the auto-immune responses
exhibited by people with certain genetic markers to OspA?
- Is the FDA aware that
"this invention was supported by National Institutes of Health Grant AR45386
and the government of the United States has certain rights thereto?"
- Is the fact that this
group of scientists, working under a grant from the government of the United
States of America, has demonstrated in this patent that "An additional problem
with OspA as a protective immunogen [i.e.: vaccine] is cross-reactivity at the
T cell level observed between OspA and LFA-1." Id. At 4, and "Given the
potential cross-reactivity between OspA and LFA-1, the use of OspA as a
protective immunogen in vaccines may be associated with the induction of an
auto-immune reaction in certain populations, including individuals expressing
the HLA-DRB1-0401 allele. Thus it would be highly desirable to generate
modified OspA polypeptides with diminished or no binding to the DRB1-0401
allele.
- How does the FDA reconcile
the fact that research conducted and completed by the principal investigator
for LYMErix prior to FDA's approval of the vaccine, and largely ignored by the
FDA or dismissed at "theoretical" in its review and oversight of LYMErix,
nevertheless led the scientists involved to pursue and patent a genetically
modified version of OspA aimed specifically at avoiding the risk of
auto-immunity from the OspA utilized in LYMErix demonstrated in that research?
- Does the FDA believe that
the medical community and the public at large should be advised of the fact
that scientists and researchers of this caliber consider the risk of auto-
immunity from LYMErix so great that they applied for, received, and worked
pursuant to, a NIH grant to produce a modified version of OspA to minimize or
eliminate the risk? If not, why?
- In light of this
documentation, why has the FDA not demanded that GlaxoSmithKline produce in
full any and all research which they claim disproves the risk of auto-immunity
from LYMErix rather than simply accepting the manufacturer's summary claims
without supporting data?
- In the abstract of the
researchers' application for the NIH Grant #1R01AR045386-0, they state that
"LFA-1/DR4 double transgenic mice on an MHC class II -/- background will be
created and tested for the development of chronic Lyme arthritis after
exposure to Bb. This is based on the observation that mouse LFA-1 does not
express the OspA cross- reactive epitope." Indeed, the researchers observed an
auto-immune arthritic reaction when these mice were exposed to natural OspA,
but not when they were exposed to the patented, modified version of OspA. In
this regard, what will the FDA do to determine what if any steps
GlaxoSmithKline took to "create and test LFA-1/DR4 double transgenic mice" for
its research, as the NIH grantees did, and whether or not the manufacturer did
produce such mice and conduct studies which supported the risk of
auto-immunity and suppressed those results? Further, what are the implications
of GlaxoSmithKline's presentation at the January 31, 2001 Advisory Committee
Meeting of a study on mice which it claimed disproved any auto-immune
arthritic risk, without revealing the fact, until questioned, that the mice
used in their study lacked the cross-reactive epitope, and therefore rendering
the study, as one member of the committee stated, "irrelevant"?
FDA said they would answer
most questions in writing since time was running short, but asked LDA to choose
a particular question. LDA's Pat Smith chose question number 5: If an individual
gets the vaccine and they show Lyme disease symptoms, how does the FDA
distinguish between 1.someone who had asymptomatic Lyme disease, 2. a new case
of Lyme (vaccine failure), 3. an immune response?
The issue, emphasized the LDA
team, was answering this question in light of all the dirty Western blots
labs have been generating from Lymerix recipients. If Lymerix Western blots are
dirty, asked LDA, how could FDA and its pharmaceutical sponsor differentiate
between actual Lyme disease and an adverse event? The question was not, just,
were the blots disguising the safety of the vaccine but, also, did the filthy
blots make it impossible to arrive at any true conclusion as to the efficacy of
the vaccine, estimated by the sponsor at almost 80 percent?"
Attempting an answer was
FDA's Karen Midthun, MD, Director, Office of Vaccine Research and Review Center
for Biologics Evaluation and Research. Midthun said vaccine investigators
attempted to confirm Lyme disease itself through culture or polymerase chain
reaction (PCR) of joint fluid, spinal fluid or the erythema migrans rash itself.
"In cases identified as definite Lyme disease," she said, "seventy to eighty
percent of the individuals were identified by culture and fifty to seventy
percent via seroconversion by Western blot."
The LDA team responded that
this answer was further proof the FDA could not, in fact, answer the question.
Indeed, no one debated cases of "definite" Lyme disease proven through culture,
but rather, those cases of "possible" Lyme disease --especially in light of the
fact that the manufacturer's studies embraced the faulty CDC standard for
Western blot by excluding consideration of two definite Lyme disease markers
--bands showing presence of Borrelia burgdorferi's two outer surface
proteins, OspA and OspB.
Commented attorney Steven
Sheller, "When I hear that disregarding OspA and OspB is not a problem, when I
hear people say there are no dirty blots, or that they are not a factor, I have
to wonder how this research was done. You can't just take the manufacturer's
word for it. You have to look at the original Western blots to come to your own
conclusion. You might just be surprised."
LDA's team advised FDA to
look at data in its rawest form in just two or three of the study sites.
Dr. Marks added that FDA
would have to rethink its notion of "statistical significance" for Lymerix.
"You'll never find statistical significance for the worst adverse events," he
told FDA, "because they are so rare. You have to look at individual patients.
You should have individual cases analyzed in depth by an impartial group of
observers." Just because an adverse event is rare, he said, does not mean it is
not associated with a vaccine. In these instances, you must weight the risk of
the disease with the risk, even if extremely low, that an individual could be
damaged by the vaccine.
FDA asked LDA if the team had
anything to add. Here, Pat Smith responded: "We have found that, due to word of
mouth on the dangers of this vaccine, physicians will no longer give it out in
their offices. Even HMOs and clinics no longer want to be involved. Instead,
Glaxo is marketing the vaccine on college campuses, where nurses who distribute
it may be unaware of the issues involved. We are very concerned that our young
students will be the next victims of this vaccine."
Smith concluded with this
query: "We want to know if you are going to do anything with the information we
have presented today."
"We'll need to discuss this
among ourselves," said FDA's Susan Ellenberg, PhD, Director, Office of
Biostatistics and Epidemiology, Center for Biologics Evaluation and Research.
"We take your presentation very seriously. Any action will be announced to
everyone in the public at the same time."
On February 25, 2002, a month
after meeting with FDA, LDA received written answers to its questions from FDA
and, also, learned that Glaxo SmithKline had quietly pulled Lymerix from the
market, citing "poor sales."
