Cyclin-dependent kinases 4 and 6 (CDK4/6) are crucial cell cycle regulators and have become significant targets in breast cancer therapy. Current CDK4/6 inhibitors, while effective, often come with adverse effects and resistance issues.
Onquality Pharmaceuticals China Ltd. has described cyclin-dependent kinase 4 (CDK4) and/or cyclin-dependent kinase 6 (CDK6) inhibitors reported to be useful for the treatment of cancer therapy-associated disorders.
Top-line phase III data from G1 Therapeutics Inc.’s pivotal Preserve 2 study of Cosela (trilaciclib) in treating metastatic triple-negative breast cancer missed its primary endpoint of overall survival, submerging the stock on June 24.
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.
Positive data from two studies treating early breast cancer with CDK4/6 inhibitors presented at the American Society of Clinical Oncology (ASCO) meeting in Chicago showed progress is helping patients live longer. The two treatments and companies, Novartis AG and Eli Lilly and Co., are nearly head-to-head competitors in the niche indication.
At the recent 2023 ASCO GI Cancers Symposium, researchers from the Royal College of Surgeons in Ireland (RCSI) presented results of a preclinical study that aimed to evaluate the potential of administering the cyclin-dependent kinase 4/6 (CDK4/6) inhibitor ribociclib with the phosphoinositide 3-kinase (PI3K) inhibitor alpelisib.
Inhibitors of cyclin-dependent kinase 4 (CDK4) and CDK6, such as palbociclib, have significantly improved progression-free survival of several breast cancer types, such as hormone receptor-positive, HER2-negative luminal breast cancers, with about 40% being unresponsive or refractory to therapy; the main cause of resistance is the selection of mutant clones in the target oncoprotein.
China’s NMPA gave the green light to Simcere Pharmaceutical Group Ltd. for Cosela (injectable trilaciclib hydrochloride) as a treatment to decrease the risk of chemotherapy-induced myelosuppression. It is intended for adult patients with extensive-stage small-cell lung cancer (ES-SCLC), before they undergo a platinum/etoposide-containing regimen.
