AUSTIN, TX / ACCESS Newswire / May 20, 2026 / Flow Pharma, Inc. announced today that it's U.S. Patent application has been allowed for issuance covering a broad-spectrum treatment for Ebola virus infections, utilizing the company's proprietary microsphere delivery technology.Unlike currently available therapies that are generally designed for specific Ebola strains, their patented approach is based on the monoclonal antibody siltuximab, which binds to a toxin released after infection with all Ebola virus strains. In preclinical studies, Flow Pharma demonstrated that siltuximab was able to effectively treat mice following an intentional exposure to Ebola virus.The patent covers both traditional intravenous administration of siltuximab and controlled-release delivery using Flow Pharma's proprietary FlowVax™ microsphere platform, which is designed to prolong therapeutic exposure following injection.&#34;We were the first group in the world to test siltuximab in a BSL-4 lab as a treatment for Ebola infection,&#34; said Dr. Reid Rubsamen, founder and CEO of Flow Pharma. Dr. Rubsamen said, &#34;Rather than targeting only a specific viral strain, the treatment described in our invention is applicable across all known Ebola virus strains. We published our data and are very excited to have this US patent application allowed bringing our IP portfolio to 10 patents and 19 patents pending.&#34;The announcement comes amidst a current Ebola outbreak of an Ebola strain with no known antiviral therapy.&#34;Siltuximab for intravenous administration has been approved for a rare disease application and has been sold for that indication by another company for over 10 years,&#34; said Miguel Yanez, a member of the Flow Pharma Board of Directors. Mr. Yanez went on to say, &#34;The composition of matter patents for siltuximab are expiring now, and we hope that we will be successful in getting FDA approval for this new indication so that the dream of a broadly applicable, universal treatment for all Ebola strains can become a reality.&#34;In addition to its Ebola therapeutic program, Flow Pharma has developed vaccine candidates targeting Ebola, Marburg, COVID-19 and multiple oncology indications using its patented FlowVax™ adjuvanted microsphere peptide vaccine platform. The platform uses naturally occurring peptide antigens packaged within synthetic biodegradable microspheres designed to stimulate targeted T-cell responses from the immune system.Flow Pharma's vaccine platform is fully synthetic and does not use mRNA, DNA transcription, live viral vectors or animal-derived products. The company's vaccine designs are based on analysis of immune responses observed in individuals who naturally overcame viral infections and cancer.The company believes the FlowVax™ platform's room-temperature stability, low manufacturing cost, and applicability across infectious disease and oncology, positions it for biodefense, pandemic preparedness and cancer immunotherapy applications.About Flow PharmaFlow Pharma, Inc. is a biotechnology company developing next-generation T-cell vaccines and immunotherapies targeting infectious diseases and cancer. Its patented FlowVax™ platform uses engineered microspheres delivering conserved peptide antigens to stimulate durable cellular immunity across multiple disease areas including Ebola, Marburg, COVID-19, influenza and oncology indications such as triple-negative breast cancer and glioblastoma.For more information, please visit Flow Pharma's website, www.flowpharma.com, or email Flow Pharma at inquiries@flowpharma.com.Forward-Looking Statements DisclaimerThis press release contains forward-looking statements within the meaning of federal securities laws, including statements about Flow Pharma's patent portfolio, therapeutic development programs, clinical potential, manufacturing capabilities and commercial plans.
