Prominent Trial Site Network Reports Inhaled Interferon Beta Study Shows Success Against COVID-19
The AIDS Clinical Trials Group (ACTG), the largest global HIV research network, which recently expanded its focus to include evaluating outpatient treatment for COVID-19, today announced that the external data and safety monitoring board (DSMB) has recommended that SNG001, an inhaled formulation of interferon beta, advance to phase 3 in the ACTIV-2 Outpatient Monoclonal Antibodies and Other Therapies Trial (ACTG A5401). SNG001 is the third agent to graduate to phase 3 in ACTIV-2, evaluating multiple investigational agents to treat early, symptomatic COVID-19 in non-hospitalized individuals.
Background
ACTIV-2 is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), which also funds the ACTG. ACTIV-2 is part of NIH’s Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV), a public-private partnership program to create a coordinated research strategy that prioritizes and speeds the development of the most promising treatments and vaccines. It also receives support from the Federal COVID Response-Therapeutics, the U.S. government’s multi-agency effort to accelerate the development, manufacturing, and distribution of COVID-19 vaccines, therapeutics, and diagnostics.
The Study Drug
The investigational product under evaluation is called SNG001, an inhaled formulation of interferon beta. Developed by Synairgen, SNG001 contains an antiviral protein called interferon beta (IFN–β), a substance produced in the lungs during viral lung infections.
The developer (Synairgen) has shown that older people with some chronic diseases have an IFN-β deficiency. Many viruses inhibit IFN-β as part of their strategy to evade the immune system.
SNG001 is self-administered as a nebulized dose (15.6 MIU) that participants inhale once daily for 14 days. Participants are trained to use the nebulizer device by study staff and take all doses at home. BRII-196/BRII-198 (a combination monoclonal antibody treatment) and SAB-185 (a novel polyclonal antibody therapy) are both currently also in phase 3 study in ACTIV-2.
The Study
Funded by the National Institutes of Health (NIH), ACTIV-2 is the first U.S. study to evaluate SNG001 (developed by Synairgen) among non-hospitalized people with COVID-19.
ACTIV-2 is a randomized, blinded, controlled adaptive platform that allows promising therapies to be added and removed throughout the study to efficiently test a variety of new agents within the same trial infrastructure. The SNG001 study is being led by William Fischer, M.D., University of North Carolina (UNC) and Upinder Singh, M.D., and Prasanna Jagannathan, M.D., both of Stanford University. Kara W. Chew, M.D. lead ACTIV-2, M.S., UCLA, and Davey Smith, M.D., University of California, San Diego (protocol chairs) and David Alain Wohl, M.D., UNC, and Eric S. Daar, M.D., Lundquist Institute at Harbor-UCLA Medical Center (vice-chairs) and supported by Dr. Currier and ACTG Co-Chair Joseph J. Eron, M.D., UNC.
“ACTIV-2 is currently evaluating treatment options that can be delivered in different ways, which is important as we aim to identify solutions that work for people who have a variety of needs,” said ACTG Chair Judith Currier, M.D., M.Sc., University of California, Los Angeles (UCLA). “In addition to a combination monoclonal antibody infusion and polyclonal antibody infusion, this nebulized, inhaled version of interferon-beta broadens potential treatment options for people who have COVID-19 but are not hospitalized, which we believe could significantly simplify care for some people with COVID-19.”
DSMB Recommendation
The ACTIV-2 DSMB recommended that SNG001 advance into a phase 3 study among participants with mild to moderate COVID-19.The planned phase 3 study will evaluate the safety and efficacy of SNG001 in reducing the risk of hospitalization and death among non-hospitalized adults with COVID-19.
About the ACTG
Founded in 1987, the AIDS Clinical Trials Group (ACTG) was the world’s first HIV research network. The ACTG conducts groundbreaking studies to improve the treatment of HIV and its complications, including tuberculosis and viral hepatitis; reduce new infections and HIV-related illness; and advance new approaches to prevent, treat, and ultimately cure HIV in adults and children. ACTG investigators and research units in 15 countries serve as major resources for HIV/AIDS research, treatment, care, and training/education in their communities. ACTG studies have helped establish current paradigms for managing HIV disease, and have informed HIV treatment guidelines, resulting in dramatic decreases in HIV-related mortality worldwide.
About Synairgen Plc
A university spin-off and public limited company, Synairgen was founded in 2003 by University of Southampton professors Stephen Holgate, Donna Davies, and Ratko Djukanovic. The company focuses on the development of respiratory disease drugs.
