Recent & Upcoming FDA Approvals: A Gamma Secretase Inhibitor Outside of Alzheimer’s, a PI3Ki Outside of Oncology, and More!

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.

Companies inked notable high-profile transactions in March 2024, including AbbVie's purchase of Landos Biopharma for $137.5M, AstraZeneca's $2.4B acquisition of Fusion Pharmaceuticals, and its subsequent deal to buy Amolyt for up to $1.05B. The FDA approved the first treatment for MASH. In parallel, expectations are high for the approval of Xcovery's ALK inhibitor, ensartinib. Praxis made headlines with PRAX-628, a next-generation oral NaV modulator, which showed anti-seizure efficacy in a Ph. IIa trial. Read below for more details on these and other drug discovery news stories from March 2024

This summary of September's major clinical updates features FDA approvals, drug withdrawals, anticipated regulatory decisions, notable trial results, new NDA submissions, clinical trial setbacks, and the initiation of new clinical trials.

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.

Relyvrio, developed by Amylyx Pharmaceuticals, is a combination treatment of sodium phenylbutyrate and taurursodiol, approved by the FDA in 2022 for ALS (“Lou Gehrig’s disease”). The approval was controversial, with an Advisory Committee initially voting against approval based on Ph. II data. Now, Ph. III data have confirmed the drug is no better than placebo in ALS, turning this phenotypic drug discovery story from two undergrads into a post-mortem highlighting the importance of clearly defined molecular mechanisms of action. This article reviews what happened and what we can learn.
