Ono Pharmaceutical, Bristol-Myers Squibb, Kyowa Hakko Kirin partner

Thursday, December 11, 2014

Bristol-Myers Squibb and Japan-based companies Ono Pharmaceutical and Kyowa Hakko Kirin have entered into a clinical trial collaboration agreement to conduct a phase I combination study with Opdivo (nivolumab), a PD-1 immune checkpoint inhibitor, and mogamulizumab, an anti-CCR4 antibody. The study, which will be conducted in Japan, will focus on evaluating the safety, tolerability and anti-tumor activity of combining Opdivo and mogamulizumab as a potential treatment option for patients with advanced or metastatic solid tumors.

Opdivo, launched in Japan in September 2014 for the treatment of patients with unresectable melanoma, is being developed in multiple tumor types in more than 50 clinical trials worldwide. Mogamulizumab was launched in Japan in May 2012 for the treatment of relapsed or refractory CCR4-positive adult T-cell leukemia-lymphoma (ATL), and granted the indication expansion in March 2014 for relapsed or refractory CCR4-positive peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL). Clinical trials with mogamulizumab in ATL, PTCL, and CTCL are ongoing in the U.S., E.U. and other countries.

Opdivo and mogamulizumab are part of a new class of cancer treatments known as immunotherapies, which are designed to harness the body’s own immune system in fighting cancer by targeting distinct regulatory components of the immune system. Opdivo binds to the checkpoint receptor PD-1 expressed on activated T-cells, blocking this pathway and enabling the immune system to attack tumors, while mogamulizumab can suppress some of the immune cells that shield the tumor from the immune system. Preclinical evidence for each therapy suggests the combination of Opdivo and mogamulizumab may lead to an enhanced anti-tumor immune response compared to either agent alone.

“Studying combination regimens of immunotherapies offers the opportunity to explore the potential of enhanced efficacy compared to current standards of care in treating cancer,” said Hiroshi Awata, member of the board of directors, vice president, executive officer and executive director of clinical development and clinical development planning, Ono.

The study will be conducted by Ono and Kyowa Hakko Kirin. Additional details of the collaboration were not disclosed.
