Monoclonal antibodies + kinase inhibitors are better than antibodies alone in breast cancer and B-cell lymphoma
The combination of Herceptin plus pan-HER (EGFR and Her 2 an 4) kinase inhibitor neratinib resulted in a 33% improvement in progression free survival versus Herceptin alone in breast cancer patients. Rituxan combined with idelalisib, PI3K inhibitor, resulted in a near doubling of progression-free survival at 24 weeks versus Rituxan, alone in patients with Chronic Lymphocytic Leukemia, non-Hodgkin’s Lymphoma, and small cell lymphoma. The news for neratinib tripled the valuation of Puma Biotechnology, while the FDA granted approval of Gilead’s drug Zydelig (idelalisib). Continue reading
