Two Potential Upcoming Approvals and Other January NDAs

In April 2024, there were promising examples of drug repurposing, significant clinical and regulatory milestones for therapies aimed at rare and pediatric diseases, the initiation of a rolling NDA submission for suzetrigine, substantial billion-dollar acquisitions, and positive trial results were reported for both a D1/D5 receptor agonist and a PARP1 inhibitor. However, the industry also had setbacks as demonstrated by the failed clinical trials for an MNK inhibitor and an NMDA receptor modulator. In case you missed anything, here’s a recap of the most notable news highlights from April 2024!

Recently, we summarized the novel small molecule drug approvals of 2023 (34/55). The remaining 21 molecular entities approved were large molecules like proteins and oligonucleotides, accounting for nearly 38% of the total approvals. Notably, seven of these large molecules have earned the prestigious Breakthrough Therapy designation, relative to the two small molecules that share this recognition. A summary of approvals for large molecule drugs, accompanied by links to FDA labels and additional information pertaining to the drug's discovery and originators, appears here.

There were 16 acquisitions of companies with small molecule drug assets in 2021 and one merger. Here is a more in-depth look into all of the lead small molecules acquired in 2021, including a review of: The lead molecules in each acquisition and their structural representations where disclosed The mechanism of action, stage, and indication of [...]

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.

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.
