Immunotherapy has changed the course of blood cancers and melanomas, but is stubbornly ineffective for the treatment of most epithelial solid cancers—the cancers that kill about 90% of the more than 600,000 Americans who die of cancer each year.
After Karen Knudsen departed from the American Cancer Society late last year, the question of where she will end up becoming the fodder for cocktail party chatter throughout oncology.
The immune system can be a powerful tool to control cancer. Immune cells within our body detect cancer cells and release payloads that kill them. Transformative science in the last decade has led to the development of therapies that enhance the ability of our immune cells to carry out this function. These therapies, including checkpoint blockade and CAR-T cells, have been lifesaving for many patients that before had untreatable cancer. But, sadly, a majority of patients with advanced solid tumors still succumb to their disease.
Orca Bio, a late-stage biotechnology company, on March 17 announced results from the pivotal phase III Precision-T study of Orca-T, its lead investigational allogeneic T-cell immunotherapy, in patients with acute myeloid leukemia, acute lymphoblastic leukemia, high-risk myelodysplastic syndrome and mixed-phenotype acute leukemia. Orca-T is manufactured using highly purified regulatory T-cells, hematopoietic stem cells and conventional T-cells derived from peripheral blood from either related or unrelated matched donors.
FDA granted traditional approval to Merck’s pembrolizumab (Keytruda) with trastuzumab, fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of adults with locally advanced unresectable or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma whose tumors express PD-L1 (CPS ≥1).
