The 2021 New Drug Approvals for Infectious Diseases: Deep Dive

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.

Leniolisib is a selective PI3Kδ inhibitor that received approval in March 2023 from the FDA as a first-in-class treatment for activated PI3K-δ syndrome (APDS), a genetic immunodeficiency disorder caused by PI3Kδ activation. The leniolisib discovery program is notable for several reasons: it is a first approval for a PI3K inhibitor outside of oncology; the first approved drug for APDS; has a novel chemotype that appears to avoid safety issues that led to black box warnings seen with other PI3K molecules; and it overcame a polymorph issue with an early lead that led to inconsistent exposures.

There continue to be opportunities for another KRAS(G12C) inhibitor to prove itself best-in-class.

This roundup highlights twelve KRAS(G12C) molecules to know, with links to recent case studies on Drug Hunter going in more detail.
