Detailed Description:

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution.

One group receives copolymer 1, a mixture of synthetic polypeptides composed of 4 amino acids, subcutaneously each day for 2 years.

The other group receives an injection of placebo daily for 2 years.
