NEW YORK, May 11, 2005 (PRIMEZONE) -- Keryx Biopharmaceuticals, Inc. (Nasdaq:KERX) today announced that the results of a phase II trial of KRX-0401 (perifosine) for patients with early prostate cancer will be presented at the annual meeting of the American Society of Clinical Oncology (ASCO) in Orlando, Florida. The presentation entitled "The AKT Inhibitor Perifosine in Biochemically Recurrent Prostate Cancer (HSPC): A Phase 2 California Consortium Trial" is scheduled for Saturday, May 14, 2005, from 8:00 a.m. to 12:00 p.m. EDT, in Hall C, level 2 of the Conference Center. KRX-0401 is a novel, oral, first-in-class inhibitor of AKT and other important signal transduction pathways.
Keryx also announced that the following combination clinical studies have now been initiated as part of its corporate-sponsored clinical program for KRX-0401:
-- Phase II combination study of KRX-0401 and Trastuzumab (Herceptin)(r), an approved human monoclonal antibody for the treatment of metastatic breast cancer. This multi-center Phase II trial will evaluate KRX-0401 in combination with Herceptin in breast cancer patients whose tumors overexpress HER2/neu and who have failed previous treatments with Herceptin(r) or Herceptin(r) plus chemotherapy. -- Phase II study of KRX-0401 in combination with endocrine therapy for patients with estrogen receptor or progesterone receptor positive metastatic breast cancer.
Other studies that have been initiated pursuant to the Keryx-sponsored clinical program include:
-- A single-agent phase I/II trial of Perifosine in the treatment of non-small cell lung cancer. -- A phase I trial of the combination of perifosine and paclitaxel. -- A phase I trial of the combination of perifosine and docetaxel. -- A phase I trial of the combination of perifosine and gemcitabine. -- A single-agent phase II trial of perifosine in patients with various tumors for which no standard therapy exists either because the tumors have become unresponsive to standard treatments or no effective form of systemic therapy has been established.
In addition to the corporate sponsored clinical program for KRX-0401, Keryx has ongoing clinical and preclinical collaborations with several prestigious medical institutions and universities, including Memorial Sloan-Kettering, MD Anderson, Dana Farber, UCSF, Emory, the National Cancer Institute and the Netherlands Cancer Institute.
Dr. Henderson commented, "Having been intimately involved as a principal investigator in the development of Herceptin(r), I am very enthusiastic about the Herceptin(r) -- KRX-0401 combination approach. I've also been very closely associated with the development of various endocrine therapies. Pre-clinical studies provide a strong rationale for undertaking these KRX-0401-Herceptin(r) and KRX-0401 endocrine therapy combination studies." Dr. Henderson added, "These studies represent the first non-chemotherapy combination studies that we have initiated. We look forward to commencing additional biologically designed combination trials for KRX-0401 in the near term."
Michael S. Weiss, Chairman and Chief Executive Officer of Keryx, stated, "We have been aggressively expanding our corporate sponsored clinical program for KRX-0401 and our goal is to start generating important data sets from this program later this year and into early next year. We also look forward to initiating additional KRX-0401 single-agent and combination studies in the near term as we continue to expand the breadth of our clinical program for the drug."
