Cleveland, OhioAges 21–65 - NCT03977753RecruitingPhase 4
Study medicine to treat common, plantar, or flat warts
This trial tests two versions of an at-home medicine to see how well they clear warts. Participants are randomly assigned to the study medicine or a placebo (inactive treatment) so researchers can compare results fairly.
BougeAges 3 years+ - NCT03966014RecruitingPhase 3
Compare different amoxicillin schedules for Lyme rash
This trial tests which schedule of amoxicillin works best for people who have the early Lyme rash called erythema migrans. It may help you choose a treatment plan that clears infection with fewer issues.
LjubljanaAges 18 years+ - NCT03965234RecruitingPhase 1/Phase 2
Lung infusion for colorectal cancer that has spread to the lungs
This trial tests a procedure where chemotherapy is delivered directly into the lungs during surgery to remove or destroy lung tumors. It aims to reduce the chance of cancer returning after surgery for people with colorectal cancer that has spread to the lungs.
Buffalo, New YorkAges 18 years+ - NCT03887481Recruiting
Brain stimulation study for a language-loss dementia subtype
This trial tests whether a painless form of brain stimulation can improve language and thinking skills in people with the logopenic variant of primary progressive aphasia (a dementia that affects language). You may receive brain stimulation along with repeated clinic visits to track changes over time.
Baltimore, MarylandAges 50–80 - NCT04004169Recruiting
Closed-loop deep brain stimulation for long-lasting depression
This study tests a special kind of brain stimulation that can adjust to your brain signals while treating major depression that has not improved with standard treatments. It may help people with severe, long-term treatment-resistant depression, but it requires brain surgery and frequent visits.
San Francisco, CaliforniaAges 22–70 - NCT03882073Recruiting
Upper arm amputation rehab study to improve hand control and feel
This trial tests a new approach for rehabilitation after an upper-limb amputation to help improve your ability to intentionally control a prosthetic and regain a sense of position (“proprioception”). You may be considered if you are planning an elective upper-arm or below-elbow amputation and can safely have surgery and follow up closely.
Bethesda, MarylandAges 18–65 - NCT03987334Recruiting
Virtual reality rehab for chronic neck pain
This trial studies whether virtual reality exercises can help reduce pain and improve function in people with chronic neck pain or whiplash. You may be invited to take part in guided VR rehab sessions if you meet the safety and health requirements.
Milan, MIAges 18–70 - NCT03829787Recruiting
Study of attention and reward signals in bipolar disorder
This study looks at how people with bipolar disorder pay attention and respond to rewards, including whether anxiety or substance use is also present. It uses eye-tracking and related tests to better understand brain patterns that may affect mood and decision-making.
Cleveland, OhioAges 18 years+ - NCT03734900RecruitingPhase 4

Common questions
- Are there clinical trials for control?
- Yes. Clin2 currently lists 2,964 recruiting control studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a control trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a control trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
