In December 2020 Cocrystal announced the selection of CDI-45205 as its lead coronavirus development candidate among a group of protease inhibitors obtained under an exclusive license agreement with Kansas State University Research Foundation (KSURF) announced in 2020.
CDI-45205 showed good bioavailability in mouse and rat pharmacokinetic studies via intraperitoneal injection, and also no cytotoxicity against a variety of human cell lines. The Company recently demonstrated a strong synergistic effect with the FDA-approved COVID-19 medicine remdesivir. Additionally, a proof-of-concept animal study demonstrated that daily injection of CDI-45205 exhibited favorable in vivo efficacy in MERS-CoV-2 infected mice. Cocrystal has obtained promising preliminary pharmacokinetic results and is continuing to further evaluate CDI-45205.
