Data Suggest Association of Connective Tissue Diseases and Collagen

FDA has been receiving inquiries from consumers and the media about an
association between collagen injections and rare connective tissue
diseases. The following may be used to respond to questions.

FDA has reached the conclusion that available data suggest a higher
incidence of these diseases, called polymyositis and dermatomyositis
(PM/DM), among people who have had collagen injections than in the general
population. These diseases are characterized by muscle inflammation and may
lead to difficulty in breathing and swallowing. The cause of PM/DM is
unknown and the natural incidence, which varies with age, sex and race, is
not well defined. Since the symptoms of persons with PM/DM are similar to
symptoms of many other diseases, PM and DM are difficult to diagnose.

Collagen, regulated as a medical device under FDA law, is injected under
the skin to correct acne scars and wrinkles. FDA, along with several other
agencies, has been reviewing a possible association between treatment with
collagen injections and the development of PM/DM. The products involved are
Zyderm and Zyplast, manufactured by Collagen Corp. of Palo Alto, Calif.

On Aug. 29, scientists from FDA, NIH, CDC and the Texas Dept. of Health reached a consensus that people who have been treated with collagen

injections seem to experience a higher than normal incidence of PM/DM. Additional information regarding the reported cases was subsequently provided by the manufacturer and evaluated by FDA's Center for Devices and Radiological Health.

FDA's conclusion about the association between collagen and PM/DM was based on an analysis of the data comparing cases of confirmed or probable PM/DM in the 400,000 people treated with collagen and the number of cases that would otherwise be expected in a similar size population with the same distribution of age, sex and race.

FDA indicated that the observed association between collagen injections and PM/DM does not necessarily mean that the injections cause the diseases. The increased number of cases among collagen-treated people could be due to factors such as pre-existing medical conditions, medications or environmental factors. Even if the injections do increase the risk of PM/DM, these diseases are extremely rare and the vast majority of collagen recipients will not develop them.

While FDA continues its studies on collagen, the agency has instructed the manufacturer to add a warning to the labels to advise doctors and

patients that the incidence of PM/DM is above the expected rate in

collagen-treated patients. The agency will also provide for a public airing of these issues.

Meeting on Collagen. and Autoimmune Diseases

On Oct. 25, FDA convened a scientific meeting to discuss the possible connection between collagen and connective tissue diseases. The scientific meeting was part of FDA's ongoing review of the safety and effectiveness of injectable collagen.

The experts noted that there is insufficient statistical or biological
evidence to support a conclusion that collagen injections cause autoimmune
or connective tissue diseases in persons without a history of these
diseases. The following may be used to respond to questions.

FDA's decision to look at the relationship between collagen and these
diseases followed a determination by government scientists that there may be
higher incidence of the diseases, called polymyositis and dermatomyositis
(PM/DM), in patients treated with collagen than would otherwise be
expected. A consensus was reached on Aug. 29 among FDA, NIH, CDC and the
Texas Dept. of Health that such an association is likely to exist based on
an analysis of reported cases.

Following further analysis of the reported cases presented at the
meeting by FDA; Collagen Corp. of Palo Alto, Calif., the manufacturer; and
the Texas Dept. of Health, the experts in the fields of immunology,

rheumatology and connective tissue diseases were asked for their views. The experts noted that limitations in the available data make it difficult to be certain about the causal relationship between collagen and PM/DM. The limitations include the difficulties in diagnosing PM/DM, the possibility that collagen-treated patients were not followed long enough and the rarity of PM/DM. Because PM and DM are so rare, even small changes in certain assumptions, such as the normal rate of PM/DM in the non-exposed population or the number of PM and DM cases among collagen treated patients, can significantly alter the results. Also, it was unclear that a specific biological mechanism could lead to PM/DM.

The uncertainty about the association and the lack of a clear biological mechanism do not mean that there is no risk of PM/DM from these injections. In this regard, FDA has informed the manufacturer to add a warning statement to the labeling about the possible association between injections and PM/DM. The agency also suggests that people considering collagen injections ask their doctors for the patient information brochure supplied by the company, which discusses the risks of collagen injections.

At least 75,000 people each year receive collagen injections for acne scars and wrinkles.

The promotion of Retin-A (tretinoin) for unapproved uses (particularly for the treatment of skin "photoaging") by Ortho Pharmaceuticals, a subsidiary of Johnson & Johnson, was the recent topic of a "60 Minutes" segment. The following chronology summarizes for you FDA's activities over the last two years with respect to this matter:

the same time, Johnson & Johnson assured FDA that their
program for generating media information on Retin-A had
ended in 1987, prior to FDA's expression of concern in
the January 1988 meeting. Johnson & Johnson admitted
that, prior to January 1988, the firm had paid certain
physicians for the promotion of Retin-A.
