AUTOIMMUNE INC. REPORTS FIRST QUARTER 1994
FINANCIAL RESULTS

-- First Oral Tolerance Pharmaceutical Advances to
Phase III Clinical Trials --

Lexington, Massachusetts, May 9, 1994 -- AutoImmune Inc. (Nasdaq: AIMM) today reported a net loss of $2.8 million, or $.27 per share, for the quarter ended March 31, 1994, compared with a net loss of $1.4 million or $.19 per share, for the same quarter a year earlier. Research and development expenses increased to $2.6 million for the first three months of 1994, from $1.5 million in the comparable 1993 period, as a consequence of expanded internal drug development activities.

"The Company has maintained its strategic focus on the development of a new class of pharmaceuticals based on oral tolerance technology, and as a result, we've achieved key milestones in the first quarter. AutoImmune now has four products in clinical testing which collectively address U.S. patient populations of more than 2.8 million individuals," said Robert C. Bishop, Ph.D., President and Chief Executive Officer of AutoImmune.

Dr. Bishop noted that accomplishments during the first quarter included the start of a Phase III double-blind placebo-controlled human trial of the Company's lead product, MyloralTM, in multiple sclerosis patients under a Company-sponsored IND; and the expansion of its laboratory facilities to accommodate a growing staff of experienced pharmaceutical personnel.

AutoImmune Inc. is developing pharmaceutical products based on the principle of oral tolerance for the treatment of immune system disorders, including multiple sclerosis, rheumatoid arthritis, diabetes and uveitis.
