Opaganib - COVID-19

Opaganib - COVID-19

RedHill is developing opaganib (Yeliva, ACB294640)1 to address the strong unmet need for therapies to decrease the severity and duration of respiratory symptoms due to SARS-CoV-2 infection (the cause of COVID-19).

Opaganib’s unique mechanism of action has both anti-inflammatory and anti-viral activities, targeting a critical host factor, minimizing potential development of resistance due to viral mutations.

The U.S. Food and Drug Administration (FDA) has cleared RedHill’s Investigational New Drug (IND) application for a randomized, double-blind, placebo-controlled Phase 2a study evaluating opaganib in patients with moderate-to-severe COVID-19 infection.

Pre-clinical data have demonstrated both anti-inflammatory and anti-viral activities of opaganib, with the potential to reduce lung inflammatory disorders, such as pneumonia, and mitigate pulmonary fibrotic damage. Several prior pre-clinical studies support the potential role of sphingosine kinase-2 (SK2) in the replication-transcription complex of positive-strand single-stranded RNA viruses, similar to coronavirus, and its inhibition may potentially inhibit viral replication. Pre-clinical in vivo studies have demonstrated that opaganib decreased fatality rates from influenza-virus infection and ameliorated Pseudomonas aeruginosa-induced lung injury by reducing the levels of IL-6 and TNF-alpha in bronchoalveolar lavage fluids. 

Approximately 140 subjects have been dosed with opaganib to date in ongoing and completed Phase 1 and Phase 2 clinical studies in oncology indications, in pharmacokinetic studies in healthy volunteers in the U.S., under the existing FDA-approved expanded access requests from physicians for individual oncology patients and under expanded access for COVID-19 patients in Israel, establishing safety and tolerability in humans both in the U.S. and ex-U.S. 

A compassionate use program with opaganib is ongoing in Israel with preliminary positive outcomes. RedHill is working diligently to expand access to opaganib to patients in additional countries.
