KIN-3248: Overcoming FGFR Resistance with a Next-Generation Pan-FGFR Inhibitor
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.

A Superagonist, A Novel Anti-Obesity Agent from a Zebrafish Screen, and More News Highlights From January 2024
Among the small molecule highlights in January’s news were a $100M+ Series A for a PARP1 + PI3Kα-focused company, clinical data with an SLC inhibitor for PKU, a 5-HT2C superagonist for seizures, and a NK1,3 dual antagonist for women’s health. A novel anti-obesity agent from phenotypic screening also made headlines, and the close of a major acquisition may bring relief to the industry. You can read about these notable scientific highlights and more below.
Leniolisib: The First PI3K Inhibitor First Approved Outside of Oncology
Leniolisib is a selective PI3Kδ inhibitor that received approval in March 2023 from the FDA as a first-in-class treatment for activated PI3K-δ syndrome (APDS), a genetic immunodeficiency disorder caused by PI3Kδ activation. The leniolisib discovery program is notable for several reasons: it is a first approval for a PI3K inhibitor outside of oncology; the first approved drug for APDS; has a novel chemotype that appears to avoid safety issues that led to black box warnings seen with other PI3K molecules; and it overcame a polymorph issue with an early lead that led to inconsistent exposures.
