Keryx Biopharmaceuticals, Inc. Commences Phase 2, Multi-Center Study of KRX-0401 for the Treatment of Refractory LeukemiaMD Anderson Cancer Center to Lead Study
NEW YORK, March 2 (HSMN NewsFeed) -- Keryx Biopharmaceuticals, Inc. (Nasdaq: KERX ) announced today the initiation of a corporate-sponsored Phase 2, multi-center, clinical program to evaluate KRX-0401 (perifosine) as a treatment for leukemia. The principal investigator for the study is Dr. Frank Giles, Professor, Department of Leukemia, at the MD Anderson Cancer Center in Houston, TX. This is the second study to be launched under the company's corporate sponsored hematological clinical program, which was announced earlier this year in connection with the initiation of a multi-center Phase II study evaluating perifosine as a treatment for multiple myeloma.
This clinical trial, entitled "Phase II Study of Perifosine in Patients with Refractory and Relapsed Leukemia," will assess the objective response rate and evaluate the pharmacokinetics and safety and tolerability of perifosine as a single agent in relapsed or refractory acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), high-risk myelodysplastic syndrome (MDS) and chronic myeloid leukemia in the blastic phase.
Dr. Giles stated, "We are delighted to have begun to treat patients suffering from refractory leukemia with perifosine", said Professor Frank Giles, Chief of Developmental Therapeutics at the University of Texas MD Anderson, Department of Leukemia. "There is an increasing focus on inhibition of the AKT pathway as a potentially rewarding anti-leukemia approach. The clinical and pre-clinical data gathered on this study will help to assess AKT as a potential target, and will tell us if perifosine is useful for these patients, who desperately need an improvement over current therapies."
I. Craig Henderson, MD, President of Keryx Biopharmaceuticals, commented, "We are extremely pleased to have Dr. Giles and his group at MD Anderson leading this important trial in relapsed and refractory leukemia, an area of high unmet medical need. Strong pre-clinical research supports the rationale for KRX-0401 as a potential treatment for leukemia in patients who have become resistant to other drugs."
Michael S. Weiss, Chairman and Chief Executive Officer of Keryx, added, "I am very pleased that our hematological clinical program for KRX-0401 continues to expand. We hope that KRX-0401 will have a positive impact on the treatment of patients with leukemia," Mr. Weiss added, "The initiation of the study today is another example of our ability to garner the support and involvement of the top cancer centers in the design and implementation of our studies."
The company anticipates launching additional hematological studies in the first half of 2006, including another corporate-sponsored DFCI -led phase I/II study evaluating the safety and efficacy of KRX-0401 and bortezomib (VelcadeŽ) therapy with or without dexamethasone for patients with relapsed or refractory multiple myeloma previously treated with bortezomib (VelcadeŽ).
KRX-0401 (perifosine) is in-licensed by Keryx from AEterna Zentaris, Inc. (TSX: AEZ ; Nasdaq: AEZS ), in the United States, Canada and Mexico.
About KRX-0401 (Perifosine)
KRX-0401 is a novel, first-in-class, oral anticancer agent that modulates AKT and a number of other key signal transduction pathways, including the MAPK and JNK pathways. Perifosine has shown single agent partial responses or long term disease stabilizations in solid tumors including sarcoma and prostate cancer.
KRX-0401, or perifosine, is the prototype of a new group of anti-cancer drugs referred to as alkylphosphocholines that block proliferation and induce the apoptosis of cancer cells. This effect is relatively specific for cancer cells compared to normal cells. The mechanism of action for these drugs is not clear. They are known to modulate signaling in a number of pathways known to function abnormally during the development of cancer. One of the pathways inhibited by the alkylphosphocholines is Akt, a pathway associated with tumor survival and growth. Akt is considered to be one of the most important cancer targets being researched today.
