Small Molecules in Oncology from Emerging Companies: 2021’s IPOs Pt. III

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.

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.

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.

or, How I Learned to Stop Worrying and Love My Own Definition. Recently I posted on “biologic drugs” which were approved in 2019 . All was well in my little scientific universe, until I received this in an email: “You recently reported "14 novel biologic drugs," referring to 'novel' biopharmaceuticals approved CDER. But, … You also include [...]
