Matrix Medical Network Collaborates with AstraZeneca on Phase III Clinical Trial for COVID-19 Long-Acting Antibody Combination

Matrix Medical Network Will Provide Mobile Health Clinics and Experienced Clinicians to Reach High Risk and Hard to Recruit Populations in AstraZeneca’s Phase III STORM CHASER Prevention Trial in the US

SCOTTSDALE, Ariz., February 3, 2021 – Matrix Medical Network® (Matrix) today announced a collaboration with global biopharmaceutical company AstraZeneca to accelerate a clinical trial in the US for AZD7442, AstraZeneca’s long-acting monoclonal antibody (LAAB) combination for the potential prevention of COVID-19. Matrix Clinical Solutions will meet eligible volunteers where they live and work with a fleet of Mobile Health Clinics and skilled clinicians, with a focus on populations more impacted by COVID-19.

Matrix is supporting the Phase III clinical trial called STORM CHASER, which will assess the safety and efficacy of AZD7442 for post-exposure prophylaxis in approximately 1,125 participants in the US and UK. Participants in this trial will include adults over 18 years of age following exposure to SARS-COV-2 and who are therefore at appreciable risk of developing COVID-19. The trial will include people living or working at long-term care facilities as well as industrial and military settings.

The Matrix and AstraZeneca teams are collaborating to rapidly develop, deploy and manage clinical research sites across the country. In a typical study, participants would need to travel to established sites often affiliated with academic medical centers in major cities which may hinder trial participation. By bringing the clinical trial to the patient via Mobile Health Clinics, Matrix is enabling further participation and creating a better experience for the patient. Matrix will lead onsite clinical trial activities including but not limited to screening, drug administration, and monitoring. Matrix will partner with more than 10 research institutions across Arkansas, California, Florida, Illinois, North Carolina, Texas, and Virginia.

“We are excited to collaborate with Matrix to help secure a diverse participant population and meet STORM CHASER participants where they live and work,” said Mark Esser, Vice President, Microbial Sciences BioPharmaceuticals R&D, AstraZeneca.

“Matrix has provided direct clinical trial operational support to several top vaccine candidates by deploying more than 20 Mobile Health Clinics and directly supporting more than 4,000 trial patient visits,” said Matrix Chief Medical Officer Daniel Castillo, M.D. “We look forward to working with AstraZeneca to reach high-risk patients where they are, helping to remove barriers to quality healthcare and access to clinical trials.”

This project has been funded in whole or in part with federal funds from the Department of Health and Human Services; Office of the Assistant Secretary for Preparedness and Response; Biomedical Advanced Research and Development Authority in partnership with the Department of Defense; Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense; under Contract No. W911QY-21-9-0001.
