| Anergen Reports Successful Completion of Phase IIa Trial of Anervax(TM) Peptide Vaccine for Rheumatoid Arthritis
 
 Anergen CEO Provides Company Update
 
 REDWOOD CITY, Calif., March 5 /PRNewswire/ -- Anergen, Inc. (Nasdaq: ANRG - news) announced that the completed
 analysis of an early Phase II trial in rheumatoid arthritis of AnervaX therapeutic peptide vaccine confirmed the conclusions of
 an earlier interim review of the study.
 
 ''The final data analysis confirms that AnervaX is safe and results in important clinical improvement in patients with rheumatoid
 arthritis in this study,'' said Barry Sherman, M.D., President and CEO of Anergen. ''AnervaX has the potential to safely arrest
 the disease at a very early step in the autoimmune process. We plan to initiate an additional Phase II study as soon as
 possible.''
 
 The Phase IIa trial was primarily intended to evaluate safety, and define the effect of AnervaX on certain biological
 mechanisms. AnervaX was evaluated in 53 subjects with active RA, whose joints were painful, tender and swollen despite
 taking methotrexate with or without oral corticosteroids. The final analysis confirms and strengthens the interim analysis of data
 from the trial which was presented at the annual meeting of the American College of Rheumatology in November 1997.
 
 Administration of AnervaX was not associated with suppression of the immune system, a major complication of many
 therapies for chronic autoimmune diseases.
 
 Clinical improvement in signs and symptoms of RA observed in patients dosed at six week intervals was clearly superior to
 that seen in the placebo group or those patients dosed at eight week intervals. Six weeks following the last injection, 7/16
 patients (44%) had an improvement in their disease severity score of at least 20%, ranging from 21 to 42%, with a mean of
 34%. Improvement in the number of painful and swollen joints is the major contributor to the composite index. In the six week
 group there was a 46% improvement in the number of painful joints (p=.12) and a 50% improvement in the number of swollen
 joints (p=.02). Persistent benefit was reflected in 7/20 (35%) patients who had greater than 20% improvement in ACR score,
 12 weeks after the final dose.
 
 AnervaX is a synthetic 20-amino acid peptide designed to block the stimulation of T cells specifically involved in the
 rheumatoid arthritis disease process, interrupting its progression. Rheumatoid arthritis is one of the world's most prevalent and
 destructive chronic autoimmune diseases. Approximately 2.5 million Americans suffer from the condition.
 
 In an update for employees and investors, Dr. Sherman reported that along with the success seen with AnervaX, the Company
 has made significant progress in preclinical development of AnergiX(TM) for rheumatoid arthritis and DiavaX(TM) for the
 prevention of Type I diabetes. With the addition of new management strength, the Company is well positioned for the
 achievement of key milestones in 1998.
 
 ''We now have robust clinical and preclinical programs directed against three major autoimmune diseases: multiple sclerosis,
 rheumatoid arthritis and diabetes, '' noted Dr. Sherman. ''In addition to the Phase IIa data on AnervaX, the Phase I AnergiX
 clinical study in multiple sclerosis progressed well, as did our preclinical with AnergiX in rheumatoid arthritis and DiavaX for
 the prevention of Type I diabetes. These developments are the basis for Anergen's future growth.''
 
 Key product development milestones for the company in 1998 are:
 
 * The filing of an Investigational New Drug (IND) application with the
 U.S. Food and Drug Administration (FDA) in the first quarter and
 subsequent initiation of a Phase I study for AnergiX in rheumatoid
 arthritis, in conjunction with our corporate partner, N.V. Organon.
 * Initiation in the third quarter of the Phase IIb study of AnervaX for
 rheumatoid arthritis.
 * Completion of the AnergiX Phase I clinical study in multiple sclerosis
 in the third quarter.
 * IND filing for DiavaX in late 1998 or early 1999  for the treatment of
 new onset Type I diabetes.
 
 Anergen, Inc. is a biotechnology company focused on advancing the treatment of autoimmune diseases. The Company is
 developing proprietary biopharmaceutical compounds designed to selectively interrupt antigen presentation or inactivate T cells
 in the immune system that mediate the disease process.
