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

Celgene Collaborates with Jounce Therapeutics on ICOS T-cell Stimulator
Checkpoint inhibitors, alone, are effective in 25% of patients when administered as a single agent. The goal of the collaboration between Celgene and Jounce is to address the other 75% of patients. The lead program is focused on ICOS, the Inducible T cell CO-Stimulator, a protein on the surface of T cells that can spur an immune response against a patient’s cancer. Continue reading
Mechanisms of Melanoma Resistance to PD-1 Checkpoint Inhibition
It is estimated that about 40 percent of patients with advanced melanoma, the deadliest form of skin cancer, will initially respond to an immunotherapy, but about a quarter of those 40 percent will relapse within three years of treatment. In order to identify the mechanisms by which resistance to PD-1 inhibition is mediated, UCLA researchers studied biopsies of melanoma tumors taken before and after treatment with Keytruda (pembrolizumab) in patients whose cancer had returned.

Glioblastoma Update – Celldex Anti-EGFRvIII Vaccine and Improves Survival; Optune Device Reduces Risk of Death
Celldex’s vaccine against the mutated epidermal growth factor receptor (EGFRvIII), reduced the risk of death from the disease by 47% in a 73-patient randomized Phase 2 study called ReACT. In addition, the survival rate at two years was 25% for patients given the vaccine versus none in the control group. It marks the first time an immunotherapy treatment has improved survival in a randomized trial of glioblastoma patients, researchers said. It is also among the first cancer vaccines to show a survival benefit. 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
DNAtrix and Merck Phase II Collaboration of Oncolytic Virus + Keytruda for Glioblastoma
DNAtrix and Merck announced a collaboration to combine oncolytic virus therapy and PD-1 inhibition – the two companies will collaborate in phase II clinical trials on a therapy to treat glioblastoma, an especially deadly cancer for which there is no cure. Continue reading
Cancer Immunotherapy – Combining Anti-CCR4 & Anti-PD-1; and CEACAM1 (TIM-3)
A collaboration between Bristol-Myers Squibb and Kyowa Hakko Kirin to test a combination of Kyowa’s Poteligeo (mogamulizumab), an anti-CCR4 antibody, and BMS’ Opdivo (nivolumab) in a Phase I/II trial in advanced or metastatic solid tumors was announced. Also, Merck announced the acquisition of cCAM Biotherapeutics for $605MM for its CM-24 monoclonal antibody that target CEACAM1. 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
Lycera’s ROR-gamma agonists for cancer immunotherapy
Celgene and Lycera entered into a $105MM collaboration on its RORϒ agonists for the treatment of cancer, as well as LYC-30937, an oral gut-directed ATPase modulator now in early-stage clinical studies. LYC-30937 is designed to treat IBD without global immune suppression. Continue reading
Cancer Immunotherapy Projections – Immune Checkpoint Inhibitors lead the way
The worldwide market for cancer immunotherapies is anticipated to grow from $1.1B in 2012 to $9B in 2022, that equals a 23/8% annual growth. Leading the growth are the immune checkpoint inhibitors.
