Another KRASG12C Inhibitor in Ph. III, Bayer’s Massive FXIa Ph. III Clinical Trial, and 21 Other Molecules in the News

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.

Several multi-million dollar acquisitions or license agreements took place in November 2023 for hot drug targets, with assets from selective PARP1 inhibitors to GLP1R agonists, and others. This recent news roundup highlights the notable acquisitions by pharma companies for rights to molecules in a range of different indications, with illustrative patent examples for undisclosed structures.

There were four novel drugs approved by the FDA in January 2022 (2 small molecules, 2 large molecules). The novel January 2022 new drug approvals appear below in this Drug Hunter minireview: See our overview of all 36 of the novel small molecule and large molecule FDA [...]

This deep dive into 2021’s novel large molecule drug approvals is the 2 nd in a series of focus articles on 2021’s novel large molecule drugs. See part one here . For each of the 16 large molecule drug approvals of 2021 (excluding vaccines), we’ll [...]

Momelotinib is a JAK inhibitor approved by the FDA in September 2023 for treating myelofibrosis. Last year, the molecule’s co-inventors, Andrew Wilks and Christopher Burns, gave a Drug Hunter Flash talk about the development of this drug with a fascinating mechanism of action.

In celebration of the molecule’s advancement, here we recap their brilliant story, including Wilks’ discovery of the JAK kinases and how he gave them their name, and the long, sometimes fraught journey of momelotinib through several companies before its acquisition and commercialization by GSK.
