ARIAD Initiates First Clinical Trial of Oral AP23573 in Combination with Doxorubicin Chemotherapy

CAMBRIDGE, Mass.--(HSMN NewsFeed)--Feb. 14, 2006--ARIAD Pharmaceuticals, Inc. (Nasdaq: ARIA ) today announced initiation of enrollment of advanced cancer patients in a Phase Ib clinical trial of its novel mTOR inhibitor, AP23573, in combination with doxorubicin - a long-standing chemotherapeutic agent and the mainstay of treatment for a broad range of cancers and hematologic malignancies. In particular, doxorubicin is widely used in soft-tissue and bone sarcomas, as well as breast, ovarian and endometrial cancers - all potential targets for AP23573 treatment.

Preliminary Phase 2 clinical results have demonstrated striking clinical-benefit responses and 6-month progression-free survival in patients with advanced sarcomas who received single-agent AP23573. The Company is on track to initiate a Phase 3 trial of single-agent AP23573 in advanced sarcomas later in 2006.

"Given the clinical-benefit responses observed to date with single-agent AP23573 in patients with advanced sarcomas and the strong mechanistic rationale for combining doxorubicin with mTOR inhibition, this trial represents an important step in our global development plan for AP23573," said Harvey J. Berger, M.D., chairman and chief executive officer of ARIAD. "We believe that this clinical study is the first trial aimed at evaluating the combination of an mTOR inhibitor and doxorubicin and highlights the favorable safety profile that we have seen with AP23573."

Doxorubicin is generally considered the current standard of care for front-line treatment of patients with sarcomas. The alkylating agent, ifosfamide, is often used in conjunction with doxorubicin in this clinical setting. Once the tolerability and optimal dosing regimen of AP23573 in combination of doxorubicin are determined, the feasibility of adding ifosfamide will be assessed. As a result, the efficacy of AP23573 along with both chemotherapies as front-line therapy in patients with sarcomas may be studied.

AP23573 is already under study in additional Phase 1b clinical trials in combination with two other widely used cytotoxic agents, paclitaxel and capecitabine.

This non-randomized, dose-escalation trial will evaluate the safety and tolerability, pharmacokinetics, and anti-cancer activity of AP23573 in combination with various doses of intravenous doxorubicin. Up to approximately 60 patients in whom doxorubicin therapy is clinically indicated will be enrolled in the trial at three centers in the United States. The trial will predominantly include patients with certain sarcomas, as well as breast, ovarian, and endometrial cancers. Additional information about this trial is available on the web at http://www.clinicaltrials.gov/ct/show/NCT00288431?order=3

Despite advances in cancer therapy, prolonged cancer remission remains difficult to achieve in many types of solid tumors. Additional treatment options are needed for patients whose cancer is progressing and unresponsive to currently available therapies. Novel molecularly targeted agents - such as AP23573 - combined with traditional cytotoxic agents - such as doxorubicin, paclitaxel, and capecitabine - are being studied in new regimens to identify more effective treatments for patients with advanced cancers.

About AP23573

ARIAD's lead product candidate, AP23573, is a novel small-molecule inhibitor of the protein mTOR, a "master switch" in cancer cells. Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism, and angiogenesis. AP23573 is currently in Phase 1 and 2 clinical trials in patients with solid tumors and hematologic cancers. AP23573 has been designated both as a fast-track product and an orphan drug by the U.S. Food and Drug Administration and as an orphan drug by the European Medicines Agency for the treatment of soft tissue and bone sarcomas. In addition to the program in oncology, ARIAD is collaborating with Medinol Ltd. to develop stents and other medical devices that deliver AP23573 to prevent reblockage at sites of vascular injury following stent-assisted angioplasty.
