How PD-1 abrogates the anti-tumor immune response

PD-1 inhibition (Figure 1) has quickly become a front-line therapy for non-small cell lung cancer and melanoma. Moreover, PD-1 and PD-L1 inhibitors are being tested in combination with other checkpoint inhibitors, targeted therapies, cancer vaccines, monoclonal antibodies, and other modalities. But, how does PD-1 blunt the anti-tumor immune response? Continue reading

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).
