To Our Shareholders:

Operating as a virtual company all of this past year, AutoImmune Inc. further lowered operating costs and improved its balance sheet while continuing efforts to maximize shareholder value. Total expenses were 34% below prior year and ending cash balances were up by 9%.

The Company’s basic strategy is to license its intellectual property to capable partners in deals that could generate significant milestone payments and/or royalties if and when products are approved for sale. At this point in time we have two such licenses. The first of these is with Teva Pharmaceutical Industries, Ltd., which is working on an oral formulation of Copaxone® (glatiramer acetate), its injectable product for the treatment of relapsing-remitting multiple sclerosis. While its first Phase III trial of the oral product is now believed unlikely to prove successful, Teva has publicly stated it intends to run additional trials in the future. The second license is with BioMS Medical Corporation (formerly known as Rycor Technology Investments Corp.), which is now analyzing final data from a positive Phase II trial of its MBP8298 product for treatment of chronic progressive multiple sclerosis. BioMS has advised the Company that it intends to start a late phase trial on this product during the latter part of 2002. AutoImmune remains optimistic that both of these products will ultimately be approved and result in substantial income for the Company.

The oral insulin arm of DPT-1, an NIH sponsored trial on the Company’s patented method to prevent type 1 diabetes, remains ongoing and is expected to cease enrollment before the end of this year. Once the last patient is entered, observation will likely continue for an additional 24 months, soon after which results should be available. If successful, AutoImmune expects a licensee will be found to complete development of a product for this indication.

Most recently, the Company has made progress in its efforts to realize with a partner the potential for Colloral® as a dietary supplement and now hopes to see product on the market before the end of this year.

The success of our licensing efforts is dependent on expanding and defending AutoImmune’s intellectual property. At year end we had 109 issued US and foreign patents, plus 9 original and continuation-in-part patent applications with numerous foreign counterparts. The majority of these deal with methods and products to induce immunological tolerance for the treatment of disease. We hope to add to this portfolio and are continue to support research efforts at the Brigham and Women’s Hospital.

With adequate cash reserves to wait for results from clinical trials on our products, we believe we are well positioned for the future and remain confident that our technology will be proven of significant therapeutic value.

I hope that you share our vision for the future.

Sincerely,

Robert C. Bishop

Chairman of the Board
