Proteolix Presents Positive Clinical Data for Carfilzomib in Multiple Myeloma at the 2009 ASCO Annu...(tiple myeloma: Preliminary results (Ab...),Health

About Multiple Myeloma

According to the American Cancer Society, in 2009, approximately 20,500 new cases of multiple myeloma will be diagnosed in the United States. Newly diagnosed patients have treatment options that include combination chemotherapeutic agents and stem cell transplantation. While many patients respond to treatment, most eventually relapse and require subsequent treatment. Few patients are ultimately cured of their disease. In spite of advances in the treatment of multiple myeloma, this year alone, approximately 10,500 patients are expected to die of the disease.

About Carfilzomib

Carfilzomib is the first in a new class of selective, irreversible proteasome inhibitors. Carfilzomib produces specific and sustained inhibition of the proteasome, leading to apoptosis in cancer cells with minimal off-target effects. In Phase 1 and Phase 2 clinical trials, carfilzomib has demonstrated single-agent activity in hematologic malignancies and solid tumors, including multiple myeloma, Waldenstrom's macroglobulinemia, mantle cell lymphoma and renal cell carcinoma.

Proteolix is conducting a comprehensive clinical development program evaluating carfilzomib for the treatment of multiple myeloma, including an ongoing accelerated approval study in heavily pre-treated relapsed/refractory patients and a Phase 2 clinical trial in relapsed patients stratified by prior treatment with bortezomib. Both Phase 2 clinical trials are being conducted by Proteolix in collaboration with the Multiple Myeloma Research Consortium (MMRC). A Phase 1b clinical trial of carfilzomib in combination with lenalidomide and dexamethasone in patients with relapsed multiple myeloma is also ongoing. In addition, Proteolix is conducting a single-agent Phase 2 clinical trial of carfilzomib in patients with recurrent or advanced solid tumors. For the la
