COVID-19 clinical trials in Washington: what to expect

COVID-19 research has shifted from the acute illness to its aftermath and its prevention. The most active area is long COVID: trials of antivirals, immune treatments and rehabilitation for fatigue, brain fog, breathlessness and rapid-heartbeat symptoms that persist months after infection. Vaccine trials test updated and next-generation vaccines, including nasal and combined flu-and-COVID shots. Treatment trials for people at high risk, and prevention studies for people with weakened immune systems, continue as well.

In Washington, recruiting covid-19 studies are concentrated in Seattle and Redmond. 5 of the 7 are run by a drug or device company, which usually means a larger study with travel reimbursement; the rest are academic or hospital-led.

Who COVID-19 trials usually look for

Long COVID trials ask for symptoms that began after a confirmed or strongly suspected infection and have lasted at least three months, often with a particular symptom named. Acute treatment trials need a positive test within the past few days plus a risk factor such as age or a chronic condition. Vaccine trials specify an age group and your vaccination history, and most want people who are generally healthy. Many trials exclude pregnancy and a recent infection or vaccination.

What taking part involves

Long COVID trials run twelve to twenty-four weeks with questionnaires, sometimes exercise or breathing tests, and visits that can often be done by phone or video; many are placebo controlled. Vaccine trials involve one or two injections, a symptom diary for a week after each, a few blood draws and follow-up calls for a year or more. Acute treatment trials start the day you enroll, with swabs and check-ins for a few weeks. Study treatment and tests are free and visits are usually paid.

Questions worth asking the study team

How many visits must be in person; the chance of placebo; whether you can continue your current treatments; what counts as documentation of your original infection; and whether you will learn your own test results.

A Clinical Study of Molnupiravir to Prevent Severe Illness From Coronavirus Disease 2019 (COVID-19) in People Who Are High Risk (MK-4482-023)
PHASE3 Cullman, Alabama +4 sites NCT06667700
This trial is looking for adults at high risk for severe illness from COVID-19. Participants will take the study drug molnupiravir or a placebo and monitor their health over time.
Recruiting
A Study to Learn About the Study Medicine Ibuzatrelvir in Adults With COVID-19 Who Are Severely Immunocompromised
PHASE3 Canoga Park, California +4 sites NCT07013474
This trial is looking for adults who are severely immunocompromised and have COVID-19. Participants will receive either ibuzatrelvir alone or with another medication to see how well it works against the virus.
Recruiting
A Study on the Safety and Immune Response of Investigational mRNA Seasonal Flu/COVID-19 Combination Vaccine in Adults
PHASE1 Anniston, Alabama +4 sites NCT07464314
This trial is looking for healthy adults aged 65 to 85 years who want to help test a new vaccine that combines protection against the flu and COVID-19. Participants will receive different doses of the vaccine or standard vaccines and will be monitored for side effects and immune response.
Recruiting
Pharmacokinetics, Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children Per Standard of Care (POPS)
N/A Phoenix, Arizona +4 sites NCT04278404
This trial is looking for children and young adults who are 21 years old or younger and are currently taking certain medications, or who have had a recent COVID-19 infection. They cannot be pregnant or have had certain recent medical procedures like dialysis, organ transplants, or other serious treatments. If you think your child might fit this description, it could be worth considering.
Recruiting
Phase III DAS181 Lower Tract PIV Infection in Immunocompromised Subjects (Substudy: DAS181 for COVID-19): RCT Study
PHASE3 Duarte, California +4 sites NCT03808922
This trial is looking for immunocompromised patients who have a lower respiratory tract infection due to parainfluenza. Participants will receive treatment with DAS181 and need to meet specific health criteria.
Recruiting
Randomized Double-Blind Placebo-Controlled Trial EValuating Baricitinib on PERSistent NEurologic and Cardiopulmonary Symptoms of Long COVID
PHASE3 Tucson, Arizona +4 sites NCT06631287
This trial is looking for adults with Long COVID symptoms that have lasted at least 6 months. Participants will compare the effects of the medication baricitinib with a placebo on their symptoms and quality of life.
Recruiting
SYNERGY-AI: Artificial Intelligence Based Precision Oncology Clinical Trial Matching and Registry
N/A Birmingham, Alabama +4 sites NCT03452774
This trial is looking for cancer patients to see if an AI tool can help match them to clinical trials. Patients will have their cancer-related biomarkers evaluated to find suitable studies for their condition.

COVID-19 clinical trials in Washington: common questions

How many COVID-19 clinical trials are recruiting in Washington?
TrialFinder currently lists 7 recruiting COVID-19 clinical trials with study sites in Washington. Results are updated regularly from ClinicalTrials.gov, the official U.S. registry of clinical studies.
Where are COVID-19 clinical trials located in Washington?
Sites for these COVID-19 trials are spread across Washington. Open any trial to see its full list of participating locations and contact details.
Do I need insurance to join a COVID-19 clinical trial in Washington?
No. Study-related care is covered by the trial sponsor at no cost to participants, including the study treatment, required lab tests and study visits. Many COVID-19 trials in Washington also compensate participants for time and travel. Health insurance is not required to search or enroll.
How do I qualify for a COVID-19 clinical trial in Washington?
Each study sets its own criteria based on age, COVID-19 diagnosis details, prior treatments, current medications and general health. The fastest way to find out is to contact a research site directly — most will pre-screen you by phone in 10 to 15 minutes at no charge. You can also create a free TrialFinder profile to be matched automatically.
Are there clinical trials for long COVID?
Yes, and they are among the most active COVID trials. Most require symptoms that have lasted three months or more after an infection and name the symptom they study, such as fatigue, brain fog or breathlessness.
Can I join a COVID vaccine trial if I am already vaccinated?
Usually yes. Most current vaccine trials test updated or next-generation vaccines in people who have been vaccinated before, and ask about the date of your last dose.
Do I need a positive test to join a COVID treatment trial?
For acute treatment, yes, within the last few days. Long COVID trials accept a past positive test or a documented clinical diagnosis, and some accept a strongly suspected infection.
