Fort Dodge, IowaAges 18 years+ - NCT05122897Recruiting
Study of plaque biofilm on temporary implant crown rings
This study looks at how plaque-biofilm (a thin layer of germs that can stick to surfaces) forms on temporary parts of dental implant crowns. If you have dental implants and are healthy and stable with gum health, your care team may use specific temporary rings to study biofilm buildup.
BaselAges 18 years+ - NCT05071079Recruiting
Study infects volunteers with a malaria germ to test treatment
This study gives healthy volunteers a controlled infection with a type of malaria (vivax) to see how the infection behaves and how well curative anti-malaria medicine works. It may help researchers better design and test future malaria vaccines and treatments.
BangkokAges 20–55 - NCT05061342Recruiting
Cancer or healthy volunteers share health and imaging survey data
This study collects information about how cancer care affects daily life, treatment side effects, and quality of life, and it stores imaging and related data for future research. You might be able to take part if you’re scheduled for treatment at the center (or you’re a healthy volunteer) and can complete the questionnaires.
Shenzhen, GuangdongAges 18 years+ - NCT05025865RecruitingEarly Phase 1
Study of reducing alcohol use with the HA35 supplement
This early-phase study tests HA35 in people who currently drink less alcohol than typical weekly drinking limits. It aims to see whether the supplement is safe and whether it affects the body in people who are not heavy drinkers.
Cleveland, OhioAges 21–65 - NCT05053867RecruitingPhase 3
Inhaled drug to treat lung bleeding in ventilated cancer patients
This Phase 3 study tests whether inhaled tranexamic acid can reduce lung bleeding (pulmonary hemorrhage) in people with cancer who are on a breathing machine. If you qualify, you may receive the study drug to help stop bleeding in the lungs.
Houston, TexasAges 18 years+ - NCT05026749RecruitingPhase 3
Azithromycin for severe RSV breathing failure in young children

Birmingham, AlabamaAges 3 days–2 years - NCT04997096Recruiting
Exercise during chemo to prevent weakness from low movement
This study tests whether a structured exercise program during chemotherapy can help prevent physical decline (“immobility,” like getting weaker or moving less) in people with certain ovarian or endometrial cancers. If you’re eligible, you may be guided to exercise while receiving standard chemo, and you’ll have blood tests to track changes.

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.
