Semaglutide to prevent weight gain after liver transplant
This trial tests semaglutide (a diabetes/weight-loss medicine) to help prevent weight gain after liver transplant. It is also looking at blood sugar and safety while you continue your transplant medicines.
Richmond, VirginiaAges 18–75 - NCT05432518RecruitingEarly Phase 1
Pilot study for surgery and new medicine in recurrent glioblastoma
This early study looks at a treatment plan (including resection/surgery and an added medicine) for glioblastoma that has come back after standard therapy. The goal is to see how well it controls tumor growth and whether it is tolerable.
Calgary, AlbertaAges 18 years+ - NCT05433103Recruiting
Blood flow restriction training for veterans with multiple sclerosis
This trial tests whether a special exercise method that briefly limits blood flow to the legs can improve strength and walking ability in people with multiple sclerosis (MS). If you have walking limitations, it may help you build fitness with less heavy resistance training—but you must be able to safely use a pressure cuff during testing.
Aurora, ColoradoAges 18–75 - NCT05439005RecruitingPhase 3
Opioid-free anesthesia for breast reconstructive flap surgery
This trial compares opioid-free anesthesia with opioid-based anesthesia during breast free-flap reconstruction surgery. It aims to see whether avoiding opioids can improve safety and comfort around the time of surgery.
ParisAges 18 years+ - NCT05442957Recruiting
BRIGHT program after head and neck cancer treatment
This trial tests a “renewed image” program (BRIGHT) compared with another option (AC) after you’ve finished treatment for certain head and neck cancers. It may help you with emotional well-being and adjustment after cancer.
Detroit, MichiganAges 18 years+ - NCT05445180Recruiting
Brain scan study of thinking in cannabis users with psychosis
This study uses brain imaging to understand how thinking works in people who use cannabis, comparing those with psychosis to people without psychosis. It may help researchers learn what brain patterns relate to thinking difficulties and how cannabis use fits in.
Montreal, QuebecAges 16–80 - NCT05447325Recruiting
Brain scans to study vaping to smoking risk
This study uses brain imaging to better predict who might start smoking cigarettes and who might increase nicotine use among young adult e-cigarette (vaping) users. It may help researchers find early warning signals so support can be targeted sooner.
Athens, GeorgiaAges 18–29 - NCT05451043RecruitingPhase 2
Durvalumab and tremelimumab plus chemotherapy with propranolol
This Phase 2 study tests whether adding propranolol to durvalumab and tremelimumab along with chemotherapy can help control advanced pancreatic cancer, liver cancer, or bile duct cancer. It aims to shrink tumors and help people live longer or feel better when the cancer can’t be cured with surgery or local treatment.
Edmonton, AlbertaAges 18 years+ - NCT05454332RecruitingPhase 4
Caffeine for premature babies right after birth
This study tests whether caffeine given to very premature babies around the time they move from fetus to newborn stage can improve outcomes. It may help babies who need support as they breathe and adapt after birth.
Porto Alegre, Rio Grande do SulAges Up to 2 hours - NCT05454969Recruiting
One-4-ALL initiative for patients, families, and care teams
This initiative includes both patient guardians and the healthcare providers who care for them. It likely tests or improves how care teams and families work together to support patients better.
Aurora, ColoradoAges 18–99 - NCT05457829RecruitingPhase 2
Testing two chemotherapy combinations for relapsed pediatric rhabdomyosarcoma
This trial compares two treatment combinations—liposomal doxorubicin plus irinotecan versus a different chemotherapy plan—in children and teens whose rhabdomyosarcoma came back or did not respond. It aims to see which option works better and is safer for children who have had prior cancer treatment.
GuangzhouAges 6 months–18 years - NCT05464888Recruiting
Animal-assisted therapy for kids’ dental visits
This study tests whether working with a trained animal can make dental checkups and cleanings easier for children ages 4 to 8. It may help reduce fear and improve how kids tolerate routine dental care.
Chapel Hill, North CarolinaAges 4–8 - NCT05465070Recruiting
Heat therapy trial for leg blood-flow problems
This trial studies whether applying heat to your legs can improve symptoms and function in people with peripheral artery disease (reduced blood flow to the legs). You may be tested with a simple blood-flow check and an MRI scan, depending on eligibility.
Indianapolis, IndianaAges 50 years+ - NCT05468255Recruiting
Study how stopping exercise affects blood sugar and blood vessels
This study looks at what happens to blood sugar levels and blood vessel health when active adults stop exercising. It may help doctors understand how quickly these changes can happen and who may be most affected.
Norfolk, VirginiaAges Any age - NCT05484739Recruiting
Testing cooling methods for heat waves in older adults
This study looks at how different cooling methods affect older adults during heat waves. It may help identify safer ways to reduce heat-related stress for people at risk.
Dallas, TexasAges 65 years+ - NCT05488288RecruitingPhase 3
Weight-loss surgery plus mesh repair for ventral hernia
This trial tests whether combining weight-loss surgery with a mesh repair for a midline ventral hernia works better and is safer than another approach. It may help people who have both severe obesity and a specific type of hernia reduce hernia problems after surgery.

Nerve block to reduce long-term pain after breast surgery
This trial tests whether a specific pain-numbing nerve block given during mastectomy can reduce chronic (long-lasting) pain after breast cancer surgery. It may help some people use less pain medicine later by lowering nerve-related pain after surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT05495087Recruiting
Breathing low-oxygen air to test brain benefits in mild memory loss
This study tests whether breathing controlled low-oxygen air (through a disposable face mask) can improve brain function in people with mild cognitive impairment (MCI). You’d be randomly assigned to the real treatment or a sham (placebo-like) control, and you’d need multiple lab visits.

Test which chamber position protects corneal clarity after glaucoma surgery
This trial studies whether placing a glaucoma drainage device tube in the front part versus the back part of the eye better preserves the cornea’s inner cell layer. You might benefit by using a tube placement that could help keep the cornea clearer for longer after surgery.

Common questions
- Are there clinical trials for control?
- Yes. Clin2 currently lists 3,039 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.
