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

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.

While KRAS(G12C) has been the most readily targeted form of KRAS thanks to its reactive cysteine residue, other mutations such as KRAS(G12D) make up the majority of KRAS-mutated cancers. In this roundup, we highlight 12 inhibitors, degraders, and other molecules that reflect progress in overcoming this challenge, including some of the first clinical candidates targeting non-KRAS(G12C)-mutant tumors, and why these molecules are notable.

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.

Nrf2/KEAP1 modulation has been pursued since the discovery that dimethyl fumarate and its metabolite protect CNS neurons via up-regulation of Nrf2-depdendent activities. Compounds with greater selectivity have been sought for many years, culminating with the approval of the KEAP1 inhibitor, omaveloxolone. Vividion disclosed their efforts to identify the covalent KEAP1 inhibitor, VVD-702. This ACS Spring 2024 disclosure is an excellent case study for covalent hit finding using chemoproteomics, covalent compound optimization, and the use of an uncommon but surprisingly stable covalent warhead.

Gleevec (imatinib) was the first tyrosine kinase inhibitor approved for the treatment of cancer and one of the first products to emerge from "rational drug design."  It's invention changed chronic myeloid leukemia from an incurable death sentence to a manageable disease. Here's a look back on the tremendous value it's created over the last [...]
