Our Bureau

RedHill Biopharma Ltd. (Nasdaq: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company, today announced that the global Phase 2/3 study with orally-administered opaganib (Yeliva®, ABC294640)[1] in patients hospitalized with severe COVID-19 pneumonia has received a unanimous recommendation to continue, following a fourth independent Data Safety Monitoring Board (DSMB) safety review. The DSMB’s recommendation is based on an analysis of unblinded safety data from the first 255 patients treated for 14 days, extending the total opaganib safety database to approximately 380 patients.

Mark L. Levitt, M.D., Ph.D., Medical Director at RedHill, said: “With approximately 380 patients in the opaganib safety database following this positive fourth DSMB review, we are building a clear picture of the safety profile of opaganib.” Dr. Levitt continued: “Moreover, adding together the positive Phase 2 data, the successful DSMB futility reviews and the outcomes from compassionate use of opaganib, we look forward with optimism to the reporting of top-line data from the Phase 2/3 study, which will provide the clearest indication to date of opaganib’s promise in treating COVID-19.”

The global Phase 2/3 randomized, double-blind, parallel-arm, placebo-controlled study of opaganib in patients with severe COVID-19 pneumonia requiring hospitalization and treatment with supplemental oxygen (NCT04467840), is over 75% enrolled in approximately 40 recruiting sites.

RedHill recently announced positive top-line safety and efficacy data from the non-powered U.S. Phase 2 study with opaganib in 40 patients with COVID-19 pneumonia, in which opaganib demonstrated greater improvement in reducing oxygen requirement by end of treatment on Day 14, on top of standard-of-care. The Phase 2 data also showed no material safety differences between the opaganib and placebo on top of standard-of-care treatment arms – further adding to the growing safety database for opaganib.
