About Biothera Pharmaceuticals

Biothera Pharmaceuticals, Inc. is advancing Imprime PGG, a unique cancer immunotherapy, through Phase 2 clinical trials in multiple cancer indications. While cancers can actively avoid detection by the immune system, Imprime PGG works as an immunological “ignition switch” to activate a host of anti-tumor immune system responses. These robust, coordinated innate and adaptive immune responses can enhance the therapeutic efficacy of immune checkpoint inhibitors and other monoclonal antibodies.  Studies in over 400 patients have demonstrated clinical proof of concept and a favorable safety profile for Imprime PGG in combination with anti-cancer antibodies. Biothera Pharmaceuticals is developing Imprime PGG, the first systemically administered Pathogen Associated Molecular Patterning (PAMP) drug, in Phase 2 combination trials with checkpoint inhibitors. Patient recruitment is underway for studies in melanoma, triple negative breast cancer and non-small cell lung cancer. A clinical study in head and neck cancer is scheduled to begin in the second quarter. Significant milestones, including response, safety and biomarker data, are expected through 2017-18.
