Immunotherapy

Immunotherapy
Triple-negative breast cancer is considered one of the most difficult to treat breast cancers, with few treatment options, but finally a breakthrough study shows progress by extending patient survival.
Combining an immune checkpoint inhibitor and a tyrosine kinase inhibitor (TKI) significantly improved progression-free survival (PFS) in treatment-naïve patients with advanced renal-cell carcinoma (RCC) compared with a TKI alone.
The combination of immunotherapy with nivolumab (Opdivo) and ipilimumab (Yervoy) may soon represent a new first-line treatment option in patients with early-stage metastatic colorectal cancer (CRC) associated with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) tumors.

The second-generation chimeric antigen receptor (CAR) T-cell therapy, bb2121, engineered to target B-cell maturation antigen, a protein on the surface of certain myeloma cells, displayed continuing efficacy and safety in an update of a phase 1 clinical trial in patients with relapsed or refractory multiple myeloma.

“The wide range of potential immune-related adverse events requires multidisciplinary, collaborative management by providers across the clinical spectrum,” according to Michael A. Postow, MD, and colleagues.

Among the 84 patients, 7 had partial responses with the combination of atezolizumab (Tecentriq) and cobimetinib (Cotellic). The median duration of response was 14.3 months.

The combination cohort consisted of 119 patients who received nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for 4 doses followed by nivolu­mab 3 mg/kg every 2 weeks. The median follow-up was 13.4 months.

“We find that T-cells with highly activated glycolysis pathways ended up performing worse when we tried to make them into CAR T-Cells. Substituting and supplementing heavily with fatty acids did seem to improve this a little,” said David M. Barrett, MD, PhD, at the 2018 American Association for Cancer Research annual meeting.

The FDA granted accelerated approval to nivolumab based on a notable clinical benefit in a subset of patients who progressed after receiving the standard first-line chemotherapy with fluoropyrimidine, oxaliplatin, and irinotecan.

“The main rationale from the cytotoxic era is to increase efficacy by combining agents that have different mechanisms and nonoverlapping toxicities. The question is whether we can replace nonspecific cytotoxic agents with a specific, more effective immunotherapeutic,” said Donna Przepiorka, MD, PhD, at ASH 2017.
