BioLink Life Sciences of Cary, North Carolina, today announced receiving a contract from BARDA (the Biomedical Advanced Research and Development Authority) to fund the development of Ramatroban for treatment of patients hospitalized with COVID-19 pneumonia (the RAMBAN-1 Study).
BioLink’s $750,000 contract from BARDA complements a multimillion dollar grant from Open Philanthropy to the Charak Foundation. RAMBAN-1 is a Phase 2/3 randomized, placebo-controlled clinical trial to evaluate Ramatroban’s safety and efficacy in speeding recovery in hospitalized patients with COVID-19 pneumonia with a 28-day course of treatment. RAMBAN-1 will also explore if the 28-day treatment of acute disease with Ramatroban reduces the risks of subsequent development of post-acute sequelae of COVID-19 (“long COVID”) over the ensuing 11 months.

This study, which will be carried out at multiple clinical sites in India, is expected to support an emergency use authorization by regulatory authorities in India for acute COVID-19 while laying the groundwork for future clinical trials treating both acute and long COVID in the United States.
Ramatroban has been approved and used in Japan for over 20 years for treatment of allergic rhinitis by twice daily oral administration. In COVID-19 ramatroban targets pathways activated by massive increases in lipid mediators including thromboxane A2 and prostaglandin D2. Clinical investigators believe that thromboxane A2 slows the blood circulation through the lungs, reduces oxygenation of blood, and promotes blood clotting while prostaglandin D2 leads to misfiring of the immune system.
In a ground-breaking case series, ramatroban use led to rapid and sustained relief of both acute respiratory distress and hypoxemia in outpatients with COVID-19 pneumonia, thereby avoiding hospitalization (Ogletree et al. 2022). The potential mechanism of action of ramatroban in COVID-19 has been reviewed recently.
Ajay Gupta MD, Chief Medical Officer of KARE Biosciences and head of the Charak Foundation stated, “We welcome the initiative by Open Philanthropy and BARDA to support development of therapeutic agents for the COVID-19 pandemic, agents that target disease development both for COVID-19 and perpetrators of future pandemics. Lipid mediators have been ignored as therapeutic targets in COVID-19 and many other diseases. Ramatroban is the only known dual receptor antagonist of both thromboxane A2 and PGD2 action. We hope to exploit the great potential of this drug for treatment of respiratory, neurological, cardiovascular, immunologic and other manifestations of SARS-CoV-2 and other infectious pathogens.”
