    AstraZeneca has joined the race to gain approval for a first-in-class, orally bioavailable selective inhibitor of CDK2 with AZD8421, which was recently disclosed at the AACR San Diego 2024 “New Drugs on the Horizon” series. CDK2-selective inhibitors are a hot area right now, with their promise to overcome the resistance against approved CDK4/6 inhibitors.Read the full case study to learn about the CDK2-selective competitive landscape, the structural and kinetic data which underpin AZD8421’s CDK-selectivity and the preclinical activity data which has propelled it into the clinic.


    In April, Novartis disclosed their clinical YAP/TAZ-TEAD PPI inhibitor and WRN helicase inhibitor, both of which are being evaluated in Ph. I trials. Cerevel’s potential first-in-class, selective partial agonist of the D1/D5 dopamine receptors for Parkinson’s disease and Revolution Medicines’ noncovalent tri-complex molecular glue that inhibits a wide range of RAS(ON) isoforms, including KRAS, NRA [...]


    BLU-222 is a potential first-in-class, orally bioavailable selective inhibitor of CDK2 discovered and currently in development by Blueprint Medicines for the treatment of advanced solid tumors. Read the full case study to learn about the competitive landscape of CDK inhibitors, the discovery story enabled by the DiscoveRx KINOMEscan screening platform, how exquisite kinome selectivity can be achieved despite ~100% active site sequence similarity between CDK1/2, how this molecule can potentially treat CCNE1-amplified and CDK4/6i-resistant tumor models, interim clinical data, and more.


    PRMT5 is an epigenetic “synthetic lethality” target that has attracted much attention among drug hunters. The first generation of PRMT5 inhibitors was limited by systemic toxicities resulting in a cooling of industry interest, until the recent identification of tumor-specific inhibitors. These second-generation compounds target the MTA:PRMT5 complex in MTAP-deleted cancers—15% of all tumors—leading to a revival of the target. Read on to find out which companies are prevailing in the search for a first-in-class PRMT5 inhibitor and how their clinical compounds differentiate.


    In April 2024, there were promising examples of drug repurposing, significant clinical and regulatory milestones for therapies aimed at rare and pediatric diseases, the initiation of a rolling NDA submission for suzetrigine, substantial billion-dollar acquisitions, and positive trial results were reported for both a D1/D5 receptor agonist and a PARP1 inhibitor. However, the industry also had setbacks as demonstrated by the failed clinical trials for an MNK inhibitor and an NMDA receptor modulator. In case you missed anything, here’s a recap of the most notable news highlights from April 2024!
