Compound class: Synthetic organic
Comment: Opaganib (ABC294640) is an orally bioavailable sphingosine kinase 2-selective inhibitor that is being investigated for clinical antiproliferative efficacy in various cancers [3]. The sphingosine kinases (SK1 and SK2) are key enzymes within the sphingolipid metabolism pathway that promote tumour growth and pathologic inflammation. Opaganib is being developed by RedHill Bio. In 2017 the FDA granted this compound orphan designation for the treatment of cholangiocarcinoma.

SARS-CoV-2 and COVID-19: A medRxiv preprint descibes the compassionate use of opaganib in a small cohort of patients with severe COVID-19 [2], predicated upon the drug's anti-inflammatory and anti-viral properties. The analysis indicated trends in favour of clinical efficacy which led to extended investigation in a Phase 2 randomised placebo-controlled trial.
