Ten Moving Targets: 2022Q1

Drug Hunter has sifted through news articles, press releases, financial disclosures, SEC filings, and more to bring you a roundup of 2023’s biggest mergers and acquisitions (M&A) in the drug discovery world. In part 3 of this 4-part series, we bring you the top-ranked small molecule-focused deals by value. Covering a range of targets and modalities, this article gives Drug Hunter members in-depth background and analysis of the hottest science opening checkbooks in 2023.

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.

DILI is a leading cause of acute liver failure, accounting for half of these cases and often resulting in drug withdrawals. Understanding and managing DILI risk as a medicinal chemist involves exploring the intricate interplay among properties and structural features. In this article, we provide a medicinal chemist's perspective on the current understanding of DILI mechanisms, highlight cutting-edge assay developments for a holistic assessment, and discuss strategies for predicting DILI risks.

KIN-3248 (Kinnate Biopharma) is a next-generation, irreversible, pan-fibroblast growth factor receptor inhibitor (FGFRi) in a first-in-human (FIH) dose-escalation study (NCT05242822) in adults with advanced tumors harboring FGFR2 and FGFR3 gene alterations. The program is an excellent case study for rational covalent drug design to address kinase mutations while maintaining sufficient PK properties for oral daily dosing in humans.
