CCRC Clinical Studies

Potential study participants talking with nurse

Advancing COVID-19 Clinical Research

The CCRC researchers are focused on the advancement of effective treatments and interventions for COVID-19, and hope to further the develop treatment medications and methods that could be accessible for community members locally and globally, outside of a hospital setting. 

The CCRC research teams have conducted clinical studies for monoclonal antibody treatments — with traditional IV administration and an intramuscular shot administration — as well as studies of oral medications to determine if they could effectively prevent progression of the disease, and antiviral oral medications in development for the treatment of COVID-19 infection. Study sponsors cover all clinical study costs and participants will not be charged for any service. The CCRC is not a hospital and will only have participation from volunteers that fit the study criteria and fully consent to participation.

Is it Safe?

Your Health is Our Priority

The COVID-19 Clinical Research Center has been designed with safety top of mind with separate entrances and exits for study volunteers, optimized medical-grade air flow, private clinic rooms, extensive cleaning & disinfecting protocols and more. If you are chosen to join a study, your health will be closely monitored and care adjusted if our team determines that it is in your best interest. You may also end the study at any time without having to provide a reason.

Who Can Participate?

Qualifying for Our Studies

Our studies are inclusive of adult participants of all races, ethnicities, and backgrounds to help Researchers understand the best treatment medicines and methods across diverse populations. The facility plans to support COVID-positive study participants as well as those that have recently recovered from COVID infection. Each study has different criteria for participation. Review each study listed below for more information on the eligibility criteria.

What are my rights?

About Informed Consent

Before you participate in a study, our researchers will make sure you understand the details of the study and all of the possible known benefits, risks and alternatives to the trial in a process known as informed consent. This time will help you learn the facts about the study before deciding to take part in the trial. Informed consent is not a contract and you always have a right to ask our team questions or end your involvement at any time during the trial. 

Current Studies — Open For Enrollment

DVX201 – Deverra Therapeutics, Inc.

A Phase 1 Study of DVX201, an Allogeneic Natural Killer (NK) Cell Therapy in Subjects Hospitalized for COVID-19

Study Purpose and Summary

This study is a Phase 1 study to determine the highest tolerated dose of an investigational cell therapy called DVX201 in patients hospitalized with COVID-19. DVX201 is an allogeneic NK (natural killer) cell therapy. NK cells are a normal part of your immune system that have the ability to identify and kill cells in the body that are infected by viruses such as COVID-19. There is evidence that both NK cell exhaustion and low numbers of NK cell in the blood occur in COVID-19 patients, and this may contribute to worsening of the infection. Therefore, infusion of healthy functional NK cells (like DVX201).

Eligibility Criteria

  • Adults 18-80 years of age
  • Willing and able to provide written informed consent to participate
  • Tested positive for SARS-CoV-2/COVID-19 (test occurred not more than 7 days prior to enrollment)
  • Experiencing at least one of the symptoms common of COVID-19 (onset no more than 7 days prior to enrollment)
  • Current hospitalization at UW Medical Center - Montlake or Harborview, and meet the following:
    • Radiographic infiltrates by imaging
    • Able to maintain a SpO2 > 93% at rest
    • Meet 2 out of the 3 following criteria: i. IL-6 < 150 pg/mL ii. CRP < 100 mg/L (10 mg/dL) iii. Ferritin < 1000 ng/mL
  • Agreement to not participate in another clinical trial of an experimental treatment for COVID-19 during the study period

Other protocol-defined Inclusion/Exclusion criteria may apply.

Past Studies — No Longer Enrolling

molnupiravir MK-4482-002 – Merck Sharp & Dohme Corp.

A Phase 2/3, Randomized, Placebo-Controlled, Double-Blind Clinical Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of MK-4482 in Non-Hospitalized Adults with COVID-19.

This study aimed to evaluate the safety, tolerability and efficacy of molnupiravir (MK-4482) compared to placebo. This study enrolled adults who had recently tested positive for SARS-COV-2 and had experienced at least one related mild or moderate symptom. Patients between the ages of 18-59 were required to have at least one pre-existing risk factor to be eligible.


sotrovimab VIR COMET TAIL - Vir Biotechnology Inc

A Phase 3 randomized, multi-center, open label study to assess the efficacy, safety, and tolerability of monoclonal antibody VIR-7831 (sotrovimab) given intramuscularly versus intravenously for the treatment of mild/moderate coronavirus disease 2019 (COVID-19) in high-risk non-hospitalized patients

This was a phase 3 study that compared the administration route of an intramuscular shot to IV infusion of sotrovimab, a monoclonal antibody with FDA emergency use authorization, for the early treatment of non-hospitalized patients with COVID-19.

REGN 2067 – Regeneron Pharmaceuticals

A Master Protocol Assessing the Safety, Tolerability, and Efficacy of Anti-Spike (S) SARS-CoV-2 Monoclonal Antibodies for the Treatment of Ambulatory Patients With COVID-19

The REGN 2067 study tested an infusion of REGN-COV2, a combination of two antibodies against SARS-CoV-2, the virus that causes COVID-19, to see whether they could: decrease the amount of virus in the body; decrease the length of time the virus is in the body; and decrease the length and severity of COVID-19 illness.

Remdesivir – Gilead Sciences, Inc

A Phase 3 Randomized, Double-Blind Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Remdesivir (GS-5734™) Treatment of COVID-19 in an Outpatient Setting

The primary objectives of this study were to evaluate the efficacy of remdesivir (RDV) in reducing the rate of coronavirus disease 2019 (COVID-19) related hospitalization or all-cause death in non-hospitalized participants with early stage COVID-19 and to evaluate the safety of RDV administered in an outpatient setting.

StopCOVID2 – Washington University School of Medicine, St Louis

Fluvoxamine for Early Treatment of COVID-19: A Fully-remote, Randomized Placebo Controlled Trial

The purpose of this research study was to determine if a drug called fluvoxamine could be used early in the course of the COVID-19 infection to prevent more serious complications like shortness of breath. Fluvoxamine is an anti-depressant drug approved by the FDA for the treatment of obsessive-compulsive disorder. The use of fluvoxamine for the treatment of COVID-19 was considered investigational, which means the US Food and Drug Administration has not approved it for this use. This study was fully-remote, which means that there is no face-to-face contact; study materials including study drug were shipped to participants' houses. People around the United States and Canada could participate.

EIDD 2801 – Ridgeback Therapeutics

This is a phase IIa, double-blind, placebo-controlled, randomized trial, designed to compare the safety, tolerability, and antiviral activity of EIDD-2801 versus placebo as measured by infectious virus detection in symptomatic adult outpatients with COVID-19.

This study was Phase 2 of Merck’s MK-4482-002 study, under Ridgeback Therapeutics. Preliminary results show a reduction in infection time with no adverse events reported that were study drug related.
