Biothera unveils updated data from Phase 2 mTNBC trial at SABCS

By Mateen Dalal

Biothera Pharmaceuticals, Inc., a renowned Minnesota based biotechnology company, reportedly announced that clinical benefit data and updated response from its Phase 2 study in chemo-refractory mTNBC (metastatic triple negative breast cancer) patients would be presented in a Spotlight Session during the 2019 San Antonio Breast Cancer Symposium (SABCS).

The Phase 2 study evaluates Biothera’s Imprime PGG, which is a systematically delivered dectin receptor triggering anti-cancer immune responses, with the anti-PD-1 therapy developed by Merck, KEYTRUDA® (pembrolizumab). The participants of the study were not treated earlier using immune checkpoint inhibitors. They also were identified as positive biomarker for Imprime PGG therapy.

Jeremy Graff, Ph.D., President and Chief Scientific Officer, Biothera Pharmaceuticals, reportedly stated that the clinical data showed compelling evidence from the combination of KEYTRUDA and Imprime PGG in chemo refractory mTNBC patients. Graff further added that the translational data not just delivers proof of concept at the cellular and molecular level, but also offers valuable insights regarding the next steps for clinical development of Imprime PGG.

Latest data from IMPRIME 1 showcased at SABCS depicted 15.9% overall response rate in mTNBC patients that were treated with the combination of KEYTRUDA and Imprime PGG.

Most of the patients showed target lesion stabilization or reduction. The discontinuation of treatment frequently resulted from increase in non-target lesion or new lesions, even when target lesions were stable or shrinking. Patients with such mixed response pattern showed an overall increase in survival.
