Cerevance’s CVN293 is an oral, CNS-penetrant, selective inhibitor of potassium efflux-mediated NLRP3-inflammasome activation in microglia for the treatment of neurodegenerative disorders. Cerevance’s NETSseq platform was used to discover a microglia-specific potassium efflux channel, KCNK13, which allows modulation of the NLRP3-inflammasome in the CNS without affecting peripheral innate immunity. Read the full article to discover highlights on the CNS-penetration of highly polar compounds and how particle size can be key to oral bioavailability

HiberCell recently disclosed the discovery of HC-7366, a potential first-in-class, intentionally discovered, orally bioavailable, potent, selective, small-molecule kinase activator of GCN2. HC-7366 has now progressed to Ph. I trials to treat ccRCC and AML. This case study is a fantastic example of how to mitigate CYP3A4 inhibition and improve oral bioavailability via judicious choice of salt formulation.

Revumenib (Revuforj®) is approved by the FDA as an oral, first-in-class menin-MLL interaction inhibitor for acute leukemia (AL). Since inhibition of the menin-MLL fusion protein interaction is selective for AL with a KMT2A translocation, it does not compromise normal hematopoietic function. This article covers the background, optimization and clinical development that has led to the approval of this groundbreaking new drug in a hard-to-treat indication.

CDI (Clostridioides difficile) infection is a leading cause of healthcare-associated diarrhea with significant morbidity and mortality, and with the rise of hypervirulent and resistant strains, novel and selective antibiotics to treat these infections are needed. Cadazolid, a hybrid antibiotic that combines pharmacophores of two classes of antibacterials, demonstrated potent activity in vitro against relevant C. difficile strains, while avoiding native gut flora. Additionally, the compound was designed to be gut-restricted, with minimal systemic circulation following PO dosing.

Novartis' NLRP3 inhibitor, NVP-DFV890, features a unique sulfonimidamide motif designed to reduce hydrolysis relative to traditional sulfonylureas. This potent compound, with promising PK in humans, is advancing through multiple clinical studies, including Ph. II trials for coronary heart disease and knee osteoarthritis. Presented by Angela Mackay at the EFMC-ISMC 2024 joint conference in Rome, this overview covers NVP-DFV890's discovery, as well as its preclinical PK and PD data.
