Renibus Therapeutics’ COVID-19 Treatment, RBT-9, Shows Antiviral Activity Against SARS-CoV-2 In Vitro

- Antiviral Activity Confirmed by Early Stage Studies Conducted through the National Institute of Allergy and Infectious Diseases Preclinical Services Program and Texas Biomedical Research Institute - Patient Enrollment for Phase 2 Trial Ongoing

DALLAS, Texas, Oct. 07, 2020 (GLOBE NEWSWIRE) -- Renibus Therapeutics, Inc., a clinical-stage biotechnology company, announced today that its investigational treatment for COVID-19, RBT-9, has demonstrated antiviral activity in vitro against SARS-CoV-2, the virus that causes COVID-19.

RBT-9 initially showcased broad antiviral activity against several enveloped viruses – as well as protective effects for vital organs, including the lungs, heart, kidneys and liver. Laboratory studies performed through the suite of preclinical services offered by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and conducted at Texas Biomedical Research Institute (Texas Biomed) have demonstrated RBT-9 inhibits viral activity of SARS-CoV-2. In particular, RBT-9 was effective at inhibiting replication of the virus.

“We are encouraged that two early stage, independent studies showed RBT-9 had notable antiviral activity against COVID-19,” said Stacey Ruiz, PhD, vice president of drug development and medical affairs at Renibus Therapeutics. “The inhibition of viral replication supports the potential of RBT-9 in treating patients with COVID-19, for which RBT-9 received FDA Fast Track designation in May and is currently being evaluated in a Phase 2 trial.”

“The antiviral efficacy of RBT-9 against SARS-CoV-2 was evaluated using in vitro assays commonly utilized in the infectious disease field to determine the antiviral potential of drugs. The study was conducted at Texas Biomed’s state-of-the-art biosafety level (BSL)-3 facilities—part of the Institute’s critical infrastructure necessary for combatting diseases such as COVID-19—that span basic discovery through preclinical development,” explained Texas Biomed Staff Scientist Varun Dwivedi, PhD. For three quarters of a century, Texas Biomed has delivered high quality and reliable scientific data, Dr. Cory Hallam, professor and vice president, business development at Texas Biomed said, “The Institute is proud to work with partners like Renibus and to continue research on the antiviral efficacy of RBT-9.”

Renibus is currently enrolling patients in a randomized, placebo-controlled Phase 2 clinical trial with RBT-9 in non-critically ill adults with COVID-19 who are at high risk of disease progression. For more information on this study, please visit NCT04364763.
