- Roche (OTCQX:RHHBY) and Merck (NYSE:MRK) are set to present data from their respective immunotherapy drugs for the treatment of triple negative breast cancer (TNBC) at December's San Antonio Breast Cancer Symposium. TNBC does not respond to either of two types of hormonal therapy or drugs that target HER2 receptors, such as Roche's Herceptin.
- Both companies' products are PD-1 inhibitors. Roche is also testing its candidate, called MPDL3280A, for the treatment of melanoma and lung, bladder, kidney, bowel and blood cancers. Merck's product, Keytruda (pembrolizumab) injection, is currently cleared for the treatment of melanoma.
- Bristol-Myers Squibb (NYSE:BMY) and AstraZeneca (NYSE:AZN) are also players in the space.
