ARC Clinical Research contributes to COVID-19 Vaccine Trial

ARC will recruit 250 ARC patients from across Central Texas to enroll in this late phase clinical trial, intended to prove the safety and efficacy of the sponsor’s vaccine compound and potentially enable this sponsor to be the first to bring a vaccine to market. 

Dr. Gretchen Crook, Principal Investigator for ARC Clinical Research, noted “It is the top priority of the United States and the world to find a successful vaccine to prevent the infection and spread of COVID-19.  This vaccine candidate has the potential to save lives and allow us to return to a way of life that will restore our economy, re-connect our friendships, and continue activities we all enjoy.  ARC Clinical Research was selected as a partner in this study based on our long track record of conducting high quality trials and our speed in enrolling study participants.”

Be a part of history

“This study offers an opportunity to be a part of history and benefit humankind.  There are 7 billion people in our world who will need access to a vaccine to prevent COVID-19 infection, and ARC Clinical Research is thrilled to have a role in bringing a vaccine to Americans”, says Jeff Repper, Director of ARC Clinical Research.

“This is not injecting the virus itself or a piece of the virus. This is studying the RNA of the virus and reproducing it and introducing that in a vaccine so our immune system can recognize it and think it’s the virus, react to it and form immunity to it,” said Dr. Anas Daghestani, CEO of ARC, during an interview with KXAN-TV.

Participants will be compensated for their time and contributions to the clinical study. All COVID-19 vaccine clinical trial services will be delivered at ARC Clinical Research Wilson Parke, located at 11714 Wilson Parke Ave., Suite 150 in Austin’s Four Points neighborhood. 

ARC Clinical Research is a division of Austin Regional Clinic, a physician-owned multispecialty medical group with 350 physicians and clinicians committed to providing comprehensive healthcare services throughout the greater Austin area.

Strict Coronavirus safety measures for care and research trials

In response to COVID-19, ARC has implemented strict safety measures at all clinics and research facilities to ensure that our patients, staff, and physicians remain safe. 

Everyone is screened before entering our clinics, sick and well patients wait in separate spaces with symptomatic patients most often waiting in cars, exam rooms are cleaned and disinfected after each visit, and ARC remains fully stocked with personal protective equipment (PPE). ARC ensures a safe environment to care for all patients and conduct clinical trials. ARC currently participates in seven other research studies at four ARC Clinical Research facilities.

To date, the Centers for Disease Control and Prevention (CDC) has reported almost 5 million COVID-19 cases and over 157,000 deaths in the US while the World Health Organization (WHO) reports more than 700,000 deaths worldwide due to the COVID-19 pandemic.
