News Release - February 1, 2006
CuraGen and TopoTarget Initiate Phase II Clinical Trial of PXD101 for T-Cell LymphomaBRANFORD, Conn., Feb. 1 (HSMN NewsFeed) -- CuraGen Corporation (Nasdaq: CRGN ) and TopoTarget A/S (Copenhagen Stock Exchange: TOPO) announced today the initiation of patient dosing in a Phase II clinical trial evaluating the efficacy and safety of PXD101, a small molecule histone deacetylase (HDAC) inhibitor, for the treatment of cutaneous T-cell (CTCL), peripheral (PTCL) and other T-cell non-Hodgkin's lymphomas (NHL). Preliminary results from this open-label, multi-center study are expected by mid-2007.
The Phase II study aims to establish the efficacy and safety of PXD101 as a single-agent treatment for CTCL, PTCL, and other T-cell NHL. Patients with T-cell NHL will be enrolled into one of two parallel arms depending on disease classification. Approximately 25 patients will initially be enrolled into the study with up to an additional 70 patients enrolled following demonstration of activity. The primary endpoint for the trial is objective disease response using standardized criteria. Secondary objectives for the study include evaluation of safety, time to response, duration of response, and survival following single-agent therapy with PXD101.
"We are excited to be exploring the role of PXD101 in the treatment of this disease. PXD101 has demonstrated excellent preclinical activity against T-cell lymphoma cancer cell lines, and HDAC inhibitors have been shown to have clinical activity against CTCL," stated Timothy M. Shannon, M.D., Executive Vice President of Research and Development, and Chief Medical Officer at CuraGen. "Despite advances in the treatment of cancer, there has been no significant improvement in survival rates for patients with NHL. We look forward to exploring the role of PXD101 to address this unmet medical need and its potential benefit for patients with T-cell lymphomas."
About T-cell Lymphoma
T-cell lymphomas are a type of NHL which arise from malignant T- lymphocytes, also known as T-cells, and account for approximately 15% of all NHL cases diagnosed in the U.S. CTCL is a slow-growing form of cancer where malignant T-cells are drawn to the skin and are usually deposited. CTCL is typically diagnosed in patients age 50 and older. There are approximately 1,500 new cases of CTCL diagnosed annually in the United States with nearly 20,000 patients living with the disease. PTCL and other T-cell NHL also involve malignant T-lymphocytes, and generally tend to be a more aggressive disease. Approximately 5,000 cases of PTCL and other T-cell NHL are diagnosed annually in the United States.
PXD101 is a promising small molecule HDAC inhibitor being investigated for its role in the treatment of a wide range of solid and hematologic malignancies either as a single-agent, or in combination with other active anti-cancer agents. HDAC inhibitors represent a new mechanistic class of anti-cancer therapeutics that target HDAC enzymes and have been shown to: arrest growth of cancer cells (including drug resistant subtypes); induce apoptosis, or programmed cell death; promote differentiation; inhibit angiogenesis; and sensitize cancer cells to overcome drug resistance when used in combination with other anti-cancer agents.
PXD101 is currently being evaluated in multiple clinical trials as a potential treatment for multiple myeloma, T-cell lymphoma, and colorectal and ovarian cancers, either alone or in combination with anti-cancer therapies. In August 2004, CuraGen signed a Clinical Trials Agreement with the National Cancer Institute (NCI) under which the NCI will sponsor several additional clinical trials to investigate PXD101 for the treatment of various cancers, both as a single-agent and in combination chemotherapy regimens. In May 2005, TopoTarget signed a Cooperative Research and Development Agreement (CRADA) with the NCI to conduct pre-clinical and non-clinical studies on PXD101 in order to better understand its anti-tumor activity and to provide supporting information for clinical trials of the therapy.
