The Multiple Myeloma Research Consortium (MMRC) and Proteolix Initiate Phase 2 Clinical Trial Investigating Carfilzomib for the Treatment of Multip...(l benefit response (CBR) time to progres...),Health

"Based on promising laboratory and clinical data, we believe that carfilzomib holds promise in treating patients with multiple myeloma, including those for whom other treatments have failed," said Sundar Jagannath, M.D., Saint Vincent's Comprehensive Cancer Center, where the first patient was enrolled. "We are excited to bring this compound into the MMRC as a critical step in bringing this new treatment to patients."

In the coming weeks, the MMRC and Proteolix will also begin enrolling an open-label, single-arm, Phase 2 study of carfilzomib in patients with relapsed multiple myeloma, who will be stratified by bortezomib (Velcade(R), Millennium Pharmaceuticals, Inc.) history.

About Carfilzomib

Carfilzomib is a structurally- and mechanistically-novel proteasome inhibitor that exhibits a high level of selectivity for the unique N-terminal threonine active sites within the proteasome. Carfilzomib is similar to bortezomib in that it is a potent inhibitor of the proteasome chymotrypsin- like activity, but unlike bortezomib, carfilzomib has shown minimal cross- reactivity with the other catalytic sites within the proteasome or across other protease classes. Phase 1 clinical studies confirmed that patients who have relapsed or progressed following multiple therapies can still achieve durable anti-tumor responses with carfilzomib. In addition to the two Phase 2 single-agent trials in myeloma and ongoing studies in lymphoma, a clinical trial in solid tumors and a trial exploring carfilzomib in combination with an FDA-approved agent will be initiated by the end of the year.

"The Phase 1 data consistently demonstrate carfilzomib anti-tumor activity in myeloma patients who have failed multiple lines of therapy,
