ArQule Reports Encouraging Phase 1 Monotherapy Data among Patients Treated with ARQ 501; Findings Highlighted in Late-Breaking Session at 97th Annual AACR Meeting
4/5/2006 Woburn, MA press release Pharmalive.com ArQule, Inc. today reported results from a Phase 1 monotherapy trial with its lead product, ARQ 501, which provided evidence of clinical tolerability and promising anti-tumor activity in cancer patients with advanced solid tumors who had failed prior treatments with chemotherapy. Data from this trial were presented by the study's principal investigator, Dr. Geoffrey I. Shapiro of the Dana-Farber Cancer Institute / Harvard Medical School, and Dr. Chiang J. Li, senior vice president and chief scientific officer of ArQule, in the late-breaking poster session at the 97th Annual Meeting of the American Association for Cancer Research (AACR) in Washington, D.C. "The exciting data presented today, combined with the potent and selective anti-cancer activity of ARQ 501 seen in a broad range of pre-clinical models, provide a strong rationale for initiating a Phase 2 clinical development program," said Dr. Stephen A. Hill, president and chief executive officer of ArQule. "These encouraging data also begin to define the clinical profile related to ARQ 501's novel mechanism of action." "ARQ 501 is being developed to selectively and broadly target cancer cells by directly activating checkpoint pathways," said Dr. Li. "We are excited by what we have seen with this novel mechanism of action. Among the patients who are evaluable for efficacy, almost half showed evidence of tumor regression or stable disease. This is particularly encouraging given that the data are from a Phase 1 dose escalation trial among patients who have failed other therapies." Study summary Subjects [...]
