PI3Kα H1047R accounts for one-third of all PI3Kα mutations and is associated with treatment resistance to targeted therapies in breast cancer treatment. In addition, treatment with selective PI3Kα inhibitors often results in significant adverse events such as hyperglycemia due to on-target toxicity.

Researchers from Bridgebio Pharma Inc. recently presented BBO-10203, a first-in-class, orally bioavailable, covalent small-molecule candidate designed to inhibit RAS-driven PI3Kα activity without affecting glucose metabolism.

Autologous chimeric antigen receptor (CAR) T-cell therapy has been one of the most recent successes in cancer treatment, but limitations, such as manufacturing, costs or antigen escape in therapies directed against only one target that leads to resistance, highlight the need for new approaches. Classical natural killer T (NKT) cells engineered to express CARs constitute a novel type of allogeneic therapy that does not require T-cell receptor (TCR) gene editing, thus avoiding graft-vs.-host disease (GVHD).

As its pharma peers continue to place big bets on antibody-drug conjugates (ADCs), Sanofi SA is ditching the only advertised ADC program in its pipeline, after it failed an independent interim analysis.

Starpharma Holdings Ltd.’s DEP docetaxel phase II trial met its primary endpoints, demonstrating antitumor activity in multiple advanced, metastatic cancers, including pancreatic, gastro-esophageal, non-small-cell lung cancer and cholangiocarcinoma.

Haisco Pharmaceutical Group Co. Ltd. has synthesized poly(ADP-ribose) polymerase 1 (PARP-1; ARTD1) inhibitors reported to be useful for the treatment of cancer.

LG Chem Ltd. has disclosed diacylglycerol kinase α (DGK-α, DGKA) inhibitors reported to be useful for the treatment of cancer.

Nanjing Shijiang Medicine Technology Co. Ltd. has described phosphorus compounds reported to be useful for the treatment of cancer.

Researchers from Blueprint Medicines Corp. presented data from a study that aimed to assess the effects of combining cyclin-dependent kinase 2 (CDK2) inhibitor BLU-222 with CDK4/6 inhibitors, such as palbociclib or ribociclib, to overcome CDK4/6 inhibitor resistance in HR-positive/HER2-negative breast cancer.
