BMS, Daiichi Sharing Breast Cancer Treatment Trial
Bristol-Myers Squibb and Daiichi Sankyo say they are collaborating on a clinical trial to evaluate the combination of BMS’ immunotherapy Opdivo (nivolumab) and Daiichi Sankyo’s investigational antibody drug conjugate DS-8201 in HER2-expressing metastatic breast and urothelial cancers. The multicenter Phase 1b open-label study will look at both dose escalation and dose expansion.
A statement says the study is expected to begin enrollment in the first quarter of 2018 in the U.S. and Europe. Under the agreement, Daiichi Sankyo will be the sponsor conducting the trial.
Daiichi says its DS-8201 is in Phase 1 clinical development for HER2-positive advanced or metastatic breast cancer and gastric cancer, HER2-low expressing breast cancer, and other HER2-expressing solid cancers. FDA granted it fast track designation for treating HER2-positive unresectable and/or metastatic breast cancer in patients who have progressed after prior treatment with HER2-targeted therapies including adotrastusumab emtansine(Genentech’s Kadcyla). It has not been approved for any indication in any country.
Opdivo’s global development program is said to include a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. It is currently approved in more than 60 countries, including the U.S., the European Union, and Japan. In 10/2015, BMS’ Opdivo/Yervoy combination regimen was the first immune-oncology combination to receive regulatory approval for treating metastatic melanoma. It is currently approved in more than 50 countries, including the U.S. and the European Union.
