Genentech’s divarasib is a KRASG12C inhibitor in Ph. III for non-small cell lung cancer, making it the most advanced KRASG12C inhibitor after the accelerated approvals of Amgen’s sotorasib and Mirati’s adagrasib. Efficacy with the molecule positions it well at a pivotal moment following sotorasib's recent FDA setback and BMS’s acquisition of adagrasib. Why divarasib is a big deal and what's notable about it in this full article.

INE963 (Novartis Institute for Tropical Diseases) is an oral, single dose, fast-acting blood-stage antimalarial candidate . The molecule was identified using a phenotypic high-throughput screening approach which has been successfully used to identify new antimalarial chemotypes . Phenotypic screens can be preferable to target-based [...]

This month’s cover molecule, Pfizer’s PF-07321332 (nirmatrelvir, API of Paxlovid) is an oral, reversible covalent SARS-CoV-2 main protease inhibitor, which has been submitted to the FDA by Pfizer for emergency approval for Covid treatment. Interim data showed Paxlovid reducing Covid hospitalization and death by 89%. It was nominated for this month’s [...]

Last year, Biogen announced that it would acquire Texas biotech Reata Pharmaceuticals for $7.3B. Reata’s lead molecule, omaveloxolone (SKYCLARYS®), an oral, reversible covalent inhibitor of the E3 ligase KEAP1, became the first drug approved for Friedrich’s Ataxia. Omaveloxolone was previously highlighted as a Molecule of the Month in July 2023. Now, this 2023 Molecule of the Year nominee reflects a historic milestone for neurological drug discovery. This comprehensive explainer dives into Nrf2 target rationale, how it works, how the drug was discovered, its synthesis, and why it’s a big deal.

VVD-214/RO7589831 is an oral covalent, reversible, and allosteric inhibitor of WRN helicase discovered by the San Diego-based biotech Vividion Therapeutics and being developed by Roche for tumors marked by microsatellite instability and/or mismatch repair deficiency. Vividion has utilized its chemoproteomics platform to discover and develop novel treatment options for oncology targets. The structure and initial preclinical pharmacology data for VVD-214 were recently disclosed at the AACR Annual Meeting 2024 in San Diego. VVD-214 is currently being evaluated in a Ph. I trial.
