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.
Learning how to activate and harness the immune system—the body’s built-in defense against disease—has brought the field of oncology to the cusp of a cure for at least some, if not many, types of cancer, according to an international authority in immuno-oncology.
The CAR product “is essentially an autologous T-cell, which is transduced using a lentiviral encoding vector for a CAR, which is specific to human BCMA,” said Dr Raje. The co-stimulatory domain that includes 4-1BB is believed to be associated with durable CAR T-cell persistence compared with the CD28 co-stimulatory domain.
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.
