Hyperprogression on Checkpoint Inhibition Immunotherapy
Results with checkpoint inhibitors nivolumab (PD-1, Opdivo), pembrolizumab (PD-1, Keytruda), and atezolizumab (PD-L1, Tecentriq) are impressive. Some patients have experienced incredible and prolonged responses. These drugs are truly modern medical breakthroughs.

Autoimmune toxicity on checkpoint inhibitors is associated with better responses
Cancer and autoimmune disorders are opposite sides of the same coin – cancer is a result of hypo-active immunity, whereas, autoimmune diseases is the result of hyper-active immunity. This is dramatically illustrated in examining side effects in patients with melanoma who receive checkpoint therapy with ipilimumab (Yervoy), which acts in the early stages of T-cell activation and priming, and nivolumab (Opdivo), which acts in the later stages of T-cell activation in the tumor microenvironment.

PD-L1 Expression correlates with outcomes in patients with melanoma
Keytruda (pembrolizumab) and Opdivo (nivolumab) are monoclonal antibodies that disrupt the PD-1 (Opdivo) / PD-L1 (Keytruda) pathway; they are approved by the FDA for the treatment of patients with unresectable melanoma, as well as other cancers including non-small cell lung cancer (NSCLC), head and neck cancer, renal cell carcinoma (Opdivo), and Hodg kin lymphoma (Opdivo). Keytruda is limited to patients with NSCLC with a tumor proportion score (TPS) of greater than 50% for PD-L1 staining. Continue reading
BMS and PsoOxus collaborate on transgenic oncolytic virus plus nivolumab
BMS paid PsiOxus $50MM upfront for exclusive rights to develop PsiOxus’ NG-348 enadenotucirev, a systemically administered oncolytic adenovirus therapeutic, in combination with Bristol-Myers Squibb’s Immuno-Oncology checkpoint inhibitor Opdivo (nivolumab) to treat a range of solid tumor types in late-stage cancer patients. This is a “big deal” – PsiOxus could receive up to $886 million in development, regulatory, and sales-based milestones, plus sales royalties. Continue reading
Opdivo combined with novel IL-2 prodrug immune stimulant
Bristol Myers Squibb (BMS) and Nektar Therapeutics announced a collaboration in which BMS’ PD-1 checkpoint inhibitor (Opdivo, nivolumab) will be combined with Nektar;s CD-122 agonist NKTR-214. Continue reading
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
New data with temozolomide plus radiation for brain cancers
The results of two studies have demonstrated that the use of temozolomide (TMZ) plus radiation increases disease-free and overall survival in patients with glioblastoma and a low grade glioma called anaplastic glioma. Continue reading
Neo-antigens for Cancer Immunotherapy
Two new companies have received substantial funding to pursue neo-antigens for cancer immunotherapy: Gritstone Oncology raised $102MM to pursue lung cancer and Neon Therapeutics raised $55MM to develop neoantigen-based therapeutic vaccines and T cell therapies to treat cancer. Continue reading
Two New Drugs Effective in Kidney Cancer – Opdivo and Cometriq
Opdivo (nivolumab – BMS) and Cometriq (cabozantinib -Exelixis) demonstrated positive results in studies of patients with kidney cancer. Renal cell carcinoma is the most common type of kidney cancer in adults, accounting for more than 100,000 deaths annually. Globally, the five-year survival rate for those diagnosed with metastatic, or advanced kidney cancer, is 12.1 percent. Continue reading
