| Anergen Announces IND Filing for Rheumatoid Arthritis Candidate, AnergiX(TM)
 
 Milestone in Collaboration With N.V. Organon
 
 REDWOOD CITY, Calif., March 17 /PRNewswire/ -- Anergen, Inc. (Nasdaq: ANRG - news)
 announced submission of an Investigational New Drug (IND) application to the U.S. Food and Drug
 Administration (FDA) to commence clinical evaluation of AnergiX for treatment of rheumatoid
 arthritis (RA). The company anticipates that the Phase I trial will begin in approximately 30 days.
 
 The filing of the IND for AnergiX represents a milestone in Anergen's collaboration with N.V.
 Organon, of Oss, The Netherlands. The drug combines an Organon peptide derived from HCgp39,
 human cartilage-derived glycoprotein, with Anergen's proprietary AnergiX technology. AnergiX
 products are designed to selectively inactivate T cells that are causing the inflammatory autoimmune
 process, without inducing generalized suppression of the immune system. AnergiX for RA will be the
 second AnergiX drug in clinical trials. The first is AnergiX for multiple sclerosis, which is currently in a
 Phase I trial. Anergen expects to complete that trial later in 1998.
 
 The Phase I trial in RA will be conducted at eight clinical centers in the U.S. and will enroll over thirty
 patients who have long standing rheumatoid arthritis and who are concomitantly taking methotrexate.
 Safety, tolerability and biological effects of AnergiX in RA will be evaluated. Secondary objectives
 include pharmacokinetic data and initial assessments of clinical activity.
 
 ''The IND submission expands the depth and value of our autoimmune therapeutic programs, and
 represents an important validation of our AnergiX technology platform,'' Barry M. Sherman, M.D.,
 President and CEO, said. ''The company has established a strong intellectual property position
 around this technology, which should bring value to our partners at Organon, as well as Anergen
 shareholders.''
 
 Dr. Sherman noted that this is the Company's second clinical entry into development of
 genomics-based treatments for rheumatoid arthritis. The first drug, AnervaX(TM), recently
 completed a Phase IIa clinical trial. The study found that administration of the therapeutic peptide
 vaccine is safe and yields persistent clinical benefit in RA patients. Anergen is planning to initiate an
 additional Phase II trial of AnervaX as soon as possible.
 
 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.
