The Immune Response Corporation Announces Publication of Phase 2 Trial Results For Rheumatoid Arthritis Treatment
PR Newswire - November 25, 1998 15:48
CARLSBAD, Calif., Nov. 24 /PRNewswire/ -- The Immune Response Corporation (Nasdaq: IMNR) announced today the publication of results from a Phase 2 double-blind, placebo-controlled trial completed last year, using IR501 Therapeutic Vaccine. This immune-based, T cell receptor (TCR) peptide therapy was used to treat 99 patients with active rheumatoid arthritis. The results appear in a paper entitled "T Cell Receptor Peptide Vaccination in Rheumatoid Arthritis: A Placebo-Controlled Trial Using a Combination of Vbeta3, Vbeta14, and Vbeta17," which was published in the journal ARTHRITIS & RHEUMATISM (Volume 41, Number 11, November 1998). The trial results suggest that patients receiving intramuscular injections of IR501 Therapeutic Vaccine (IR501) combined with Incomplete Freund's Adjuvant (IFA) showed statistically significant improvement when compared with patients receiving only IFA.
During the study, 31 patients received 90 micrograms of IR501, 35 patients received 300 micrograms of IR501, and 33 patients received IFA alone as a control. The study medication and placebo were administered as a single intramuscular injection (1 ml) at weeks 0, 4, 8, and 20. In conservative efficacy analyses, based on the American College of Rheumatology 20% improvement criteria, the 90-microgram dosage group showed a significant decrease in disease symptoms, including swollen joints and arthritis-related pain, compared with control patients at the 20-week time point. Larry Moreland, M.D., principal investigator, noted: "The observation that the 90-microgram dosage group showed a statistically significant treatment effect in the conservative analysis warrants additional studies to further investigate the potential usefulness of this therapy as a treatment for rheumatoid arthritis." As a follow-up to the Phase 2 trial that is the subject of this publication, the Company has recently completed a Phase 2b trial using the IR501 Therapeutic Vaccine and anticipates releasing the results by the end of 1998.
