2021 Drug Discovery Biotech IPO Trends

This article highlights million-dollar molecules that were recently in the news with related patent applications that give clues to their structures and properties. This edition includes Maze’s glycogen synthase 1 (GYS1) inhibitors that were recently licensed to Sanofi, allosteric androgen receptor (AR) modulators that may be of interest to targeted protein degradation researchers, brain-penetrant HER2 and ROCK2 inhibitors, and MDM2 degraders.

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. Following our open-access industry overview, in the final installment of this four-part series we bring you the biologics-focused deals opening checkbooks in 2023.

NaV1.8 has become an industry focal point in the pursuit of pain therapeutics thanks to the success of Vertex’s selective inhibitor, VX-548, in Ph. III clinical trials for acute pain and Ph. II results in diabetic peripheral neuropathy. Unlike opioid receptor modulation, NaV1.8 inhibition does not carry the same addiction risks in part due to its lack of expression in the brain. Following our recent review of the leading NaV1.8 inhibitor VX-548, this article provides more details on the history of target validation for NaV1.8 in pain and why this could be the new frontier for pain management.

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.

NaV1.8, a member of the voltage-gated sodium channel (NaV) family, is predominantly expressed in peripheral sensory neurons. Based on rodent NaV1.8 knockout and knockdown studies and a 2012 report of gain-of-function mutations in humans, NaV1.8 has been linked to nociceptive, inflammatory, and neuropathic pain, including chronic neuropathic pain. This compound roundup provides a historical recap of both preclinical and clinical NaV1.8 inhibitors that shaped the landscape for the new era of pain management we are witnessing today.
