In 2021 there were: 50 novel drugs approved by the FDA 27 that CDER considers first-in-class (FIC) 16 first-in-class small molecules (according to CDER) These drugs are the first in their therapeutic class to have a particular mechanism of action [...]

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 [...]

together with Dr. Jennifer Huen, Saumil Patel, and Dr. Naveed Yasin In 2021, the FDA approved 9 non-radiological novel small molecule drugs for oncology. Excluding melphalan flufenamide, which has already been withdrawn, the remaining FDA-approved novel small molecule oncology drugs of 2021 are: umbralisib (PI3Kδ and CK1ε inhibitor) sotorasib [...]

Whereas covalent drugs were once considered risky for indications other than cancer due to the potential for idiosyncratic drug-induced liver injury and other toxicities, concerns appear to have softened as an increasing number of non-oncology covalent inhibitor programs have achieved successful outcomes. Here we highlight several recent anecdotes in covalent inhibitor drug discovery that seem to reflect these changing attitudes, including billion-dollar acquisitions and approvals outside oncology, and a few modern examples that showcase the increasingly rich science in this area.

In 2022, Turning Point Therapeutics ($TPTX) was acquired by BMS for a whopping $4.1 billion in cash. In November 2023, the most advanced molecule from Turning Point, repotrectinib, was approved for the treatment of ROS1+ NSCLC. This article explores the science behind repotrectinib, what made Turning Point so valuable, how we know, and what's next. [...]
