We have previously reviewed anti-CD38 monoclonal antibody Darzalex (daratumumab) in multiple myeloma. Daratumumab targets CD38-expressing myeloma cells through a variety of immune-mediated mechanisms (complement-dependent cytotoxicity, antibody-dependent cell-mediated cytotoxicity, and antibody-dependent cellular phagocytosis) and direct apoptosis with cross-linking of receptors.

A Phase 2 study of necuparanib (from Momenta Pharmaceuticals) was halted following an interim futility analysis. The data and safety monitoring board (DSMB) ran the analysis once 57 patients in the 120-person trial had died, leading to the conclusion that necuparanib was showing insufficient efficacy to justify continuing the study.

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
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
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.

BMS (Bristol Myers Squibb) acquired all of the outstanding capital stock of Cormorant, the private, Stockholm-based biotech company developing HuMax-IL8, for $520MM. HuMax-IL8, which is currently in Phase I/II trials, is a monoclonal antibody that targets interleukin-8 (IL-8), a protein is expressed by many solid tumors. IL-8 also suppresses the immune system and increases the ability of tumors to metastasize. Continue reading
Vaccine strategies for cancer immunotherapy depend on the induction of dendritic cells (DC) in close proximity to T cells. This is best accomplished in lymphoid tissue. However, directing vaccines to lymphoid tissue has been quite challenging. Continue reading
A growing understanding of genetic variation both between histologically similar tumors from different patients and within individual tumors themselves is shedding light on the difficulties in treating cancer and developing biomarkers to diagnose it. It has long been known that a single tumor displays differences in morphology, nuclear shape, proliferation, and proportions of constituent cell types. However, these differences may be only be the “tip of the iceberg” as vast genetic and epigenetic variations that underlie them have been discovered between and within tumors. Continue reading
In a phase II randomized trial, adding IMAB362 to standard chemotherapy increased progression-free survival (PFS) and overall survival (OS) by about 50% compared with the standard treatment alone. Continue reading
