September 2020—Acute myeloid leukemia was one of the first diseases for which T cells were incorporated into the therapeutic paradigm, in the form of allogeneic stem cell transplant and donor lymphocyte infusion. Why then are there no approved immune therapies, or more specifically checkpoint inhibitors, for this T-cell–sensitive disease?

April 2020—IMpassion130 was the first phase three trial to demonstrate a clinical benefit of cancer immunotherapy in patients with PD-L1-positive metastatic triple-negative breast cancer, and based on the data, atezolizumab plus nab-paclitaxel is approved for this indication. In the trial, the Ventana SP142 PD-L1 assay with a one percent or greater cutoff was used to evaluate PD-L1 expression in immune cells. But questions remained about how to best identify patients who could benefit from the drug combination, Hope S. Rugo, MD, professor of medicine and director of breast oncology and clinical trials education at the University of California San Francisco Comprehensive Cancer Center, said in a CAP TODAY webinar last November.

December 2016—Barry Nelson was the first in his cancer patient support group to undergo immunotherapy, which at the time was in a phase one clinical trial at Dana-Farber Cancer Institute. As the therapy became available to others in his group, they would ask for his advice on whether to try it. For the answer, he’d suggest they consult with their doctors and pray. He’d add, “I hope if you decide to go with it that you’ll have the same results that I do.”

March 2016—It’s not every day that a monoclonal antibody leads the news. But when former president Jimmy Carter was successfully treated for metastasized melanoma last year with the new drug pembrolizumab (Keytruda), the story made headlines. Carter’s recovery—surprising to many when it was announced in December—may have been helped by traditional radiation and chemotherapy. However, the role played by pembrolizumab spotlighted immunotherapy as an exciting advance in the evolution of cancer treatment.
