RedHill Biopharma Further Expands Opaganib Manufacturing Capacity for COVID-19 with Cosmo Pharmaceuticals
"We are delighted to further strengthen our partnership with RedHill on expanded opaganib manufacturing, and to play a part in trying to help alleviate the suffering the coronavirus pandemic is causing across the world, should opaganib be approved for use," .
The global Phase 2/3 study of opaganib in severe COVID-19 pneumonia (NCT04467840) is ongoing, with patients enrolled in more than 30 sites in multiple countries. An interim independent Data and Safety Monitoring Board (DSMB) futility analysis will be conducted in the coming days, evaluating data from the first 135 subjects that have reached the primary endpoint. The study has previously undergone two unblinded independent DSMB safety data reviews, with unanimous recommendations to continue the study.
Preliminary data from a non-powered U.S. Phase 2 study of 40 hospitalized patients recently showed that opaganib was safe and demonstrated greater improvement in reducing oxygen requirement by end of treatment on Day 14 across key primary and secondary efficacy outcomes, correlating with clinical improvement as defined by the World Health Organization (WHO) ordinal scale.
Opaganib, a new chemical entity, is a proprietary, first-in-class, orally-administered, sphingosine kinase-2 (SK2) selective inhibitor with demonstrated dual anti-inflammatory and antiviral activity that targets a host cell component of viral replication, potentially minimizing the likelihood of viral resistance. Opaganib has also shown anticancer activity and has the potential to target multiple oncology, viral, inflammatory, and gastrointestinal indications.
Opaganib received Orphan Drug designation from the U.S. FDA for the treatment of cholangiocarcinoma and is being evaluated in a Phase 2a study in advanced cholangiocarcinoma and in a Phase 2 study in prostate cancer. Opaganib is also being evaluated as a treatment for COVID-19 pneumonia in a global Phase 2/3 study and has demonstrated positive safety and efficacy signals in preliminary top-line data from a U.S. Phase 2 study.
Preclinical data have demonstrated anti-inflammatory, antiviral and anti-thrombotic activities of opaganib, with the potential to ameliorate inflammatory lung disorders, such as pneumonia, and mitigate pulmonary fibrotic damage. Opaganib demonstrated potent antiviral activity against SARS-CoV-2, the virus that causes COVID-19, completely inhibiting viral replication in an
model of human lung bronchial tissue. Opaganib also demonstrated reduced blood clot length, weight and total thrombus score in a preclinical model of Acquired Respiratory Distress Syndrome. Additionally, preclinical
studies have demonstrated that opaganib decreased fatality rates from influenza virus infection and ameliorated
-induced lung injury by reducing the levels of IL-6 and TNF-alpha in bronchoalveolar lavage fluids.
Opaganib was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful preclinical studies in oncology, inflammation, GI, and radioprotection models, as well as a Phase 1 clinical study in cancer patients with advanced solid tumors and an additional Phase 1 study in multiple myeloma.
The development of opaganib has been supported by grants and contracts from U.S. federal and state government agencies awarded to Apogee Biotechnology Corp., including from the NCI, BARDA, the U.S. Department of Defense and the FDA Office of Orphan Products Development.
The ongoing studies with opaganib are registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health, which provides public access to information on publicly and privately supported clinical studies.
