AutoImmune Inc. Reports 2004 First Quarter Financial Results

PASADENA, Calif., May 12 /PRNewswire-FirstCall/ -- AutoImmune Inc. today reported a net loss of $0.17 million, or $0.01 per share basic and diluted, for the three months ended March 31, 2004, compared with net income of $1.03 million, or $0.06 per share basic and diluted, for the three months ended March 31, 2003. Results for the three months ended March 31, 2003 reflect receipt of the final payment in March 2003 from a subsidiary of Elan Corporation plc for its purchase of AutoImmune’s rights to certain patent applications. As of March 31, 2004, the Company reported $10.5 million in cash and marketable securities as compared to $10.7 million in cash and marketable securities as of December 31, 2003.

Robert C. Bishop, Ph.D., Chairman of the Board and Chief Executive Officer stated, “AutoImmune continues to move forward through the efforts of its licensees and its joint venture for the manufacture, marketing and sale of Colloral(R) as a nutritional supplement. We should soon begin to see the impact of marketing efforts underway to support Colloral and remain optimistic sales will increase throughout the year. Under the currently applicable accounting model, AutoImmune will begin to recognize income when profits exceed cumulative start-up costs.”

AutoImmune has exclusively licensed certain of its intellectual property rights to BioMS, a Canadian company. Under the license agreement, BioMS makes monthly diligence payments to AutoImmune and has a royalty obligation on sales of MBP8298 should it reach the market. On March 18, 2004, BioMS reported that it raised Canadian $9.3 million the proceeds of which will principally be applied toward a pivotal human clinical trial of its lead drug, MBP8298, a treatment for secondary progressive multiple sclerosis, which utilizes the intellectual property rights licensed from AutoImmune.

AutoImmune has also exclusively licensed certain of its intellectual property rights to Teva Pharmaceutical Industries, Ltd. Teva has not yet started new human clinical studies on an oral formulation of COPAXONE(R) (glatiramer acetate), a product for the treatment of multiple sclerosis, but is expected to do so within the next several months. The oral formulation utilizes the intellectual property rights licensed from AutoImmune. If Teva is successful in bringing this product to market, AutoImmune will receive both a milestone payment and a royalty on sales under its license agreement.

AutoImmune is a biopharmaceutical company involved in the development of a new class of mucosally administered therapies for the treatment of autoimmune and cell-mediated inflammatory diseases and conditions.
