asundexian (BAY2433334) is a reversible Factor XIa active site inhibitor previously disclosed at the 2021 EFMC-ISMC conference . This article highlights the Ph. I data of asundexian in healthy volunteers, showing that the drug is well tolerated, with no clinically relevant bleeding-related adverse events or any relevant CYP3A4 modulation. The [...]

Bexotegrast is a dual-selective αvβ6-αvβ1 integrin inhibitor with surprising efficacy and safety data from a Ph. II trial in idiopathic pulmonary fibrosis (IPF). The αv integrins have been studied for decades in indications such as cancer and IPF. Both small molecule and antibody-based integrin inhibitors have demonstrated preclinical toxicities in non-human primates. This article highlights the unmet need for effective therapies for IPF and related conditions, a comparison of bexotegrast with other integrin binders, and possible reasons why bexotegrast is different in terms of safety.

The Merck CETP inhibitor backup, MK-8262 , is potential best-in-class CETP inhibitor, which was only discontinued as a backup due to the success of its predecessor, anacetrapib in Ph. III. Reviewer Kim Huard thought this CETP inhibitor was a great piece of work from Merck, and is a great example how to deal with a very lipophilic binding site [...]

Nerandomilast (BI 1015550) is Boehringer Ingelheim’s PDE4B inhibitor with demonstrated clinical potential in treating IPF.

The BMS factor XIa inhibitor, milvexian (BMS-986177), is an oral antithrombotic with a Ki of 0.11 nM. A member of this macrocyclic series was previously highlighted as one of 2020’s Molecules of the Year . Poor pharmaceutic properties from previous preclinical molecules such as solubility were addressed resulting in this candidate. Milvexian [...]
