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.
Fort Worth, TexasAges 55–79 - 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+ - NCT05501834Enrolling by invitation
Anxiety study for kids getting arm pins removed
This study tests if a child life specialist can help reduce anxiety when children have pins removed from their arm after a fracture. If your child is between 3 and 10, had a specific arm fracture treated with pins at Boston Children's Hospital, and speaks English, they may be eligible.
Boston, MassachusettsAges 3–10 - NCT05464888Recruiting
Animal-assisted therapy for kids’ dental visits

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+ - NCT05496491Recruiting
Before-surgery radiation and chemo for rectal cancer
This study tests a specific “before surgery” treatment (radiation plus chemotherapy), followed by more chemotherapy to improve outcomes in people with certain types of rectal cancer. You might be considered if your cancer is locally advanced but not spread to distant organs.
LarissaAges 18–80 - 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 - NCT05424003RecruitingPhase 2
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 - 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 - 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 - NCT05415384Recruiting
Cryotherapy plus surgery for broken ribs
This trial tests whether adding cryotherapy (freezing treatment to the injury area) to standard surgery for broken, displaced ribs can improve recovery. It’s for adults with multiple broken ribs who are getting a surgical stabilization procedure soon after injury.
Winston-Salem, North CarolinaAges 18–80 - 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+ - NCT05421416RecruitingPhase 2
Loratadine to prevent bone pain after stem cell transplant treatment
This trial tests loratadine (an allergy medicine) to see if it can prevent bone pain caused by a growth-factor injection used during lymphoma or multiple myeloma treatment. It may help reduce pain around the time you get that injection and your upcoming stem cell transplant.
Edmonton, AlbertaAges 18 years+ - NCT05422690RecruitingPhase 2
Treating bile duct cancer with chemo plus Y-90 radiation
This Phase 2 study tests whether combining chemotherapy (gemcitabine and cisplatin) and an immunotherapy drug (durvalumab) with targeted Y-90 radiation can shrink inoperable intrahepatic cholangiocarcinoma tumors. It’s looking for better tumor shrinking and improved cancer control.
Fairfax, VirginiaAges 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+ - 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 - NCT05327647RecruitingPhase 2
Bicalutamide with BCG for bladder cancer after BCG treatment
This trial studies whether bicalutamide can improve outcomes for people with non-muscle-invasive bladder cancer who are starting BCG through the bladder. It may help prevent cancer from coming back or progressing after BCG.
London, OntarioAges 18 years+ - NCT05403151Recruiting
Healthy blood vessel and control study
This study looks at healthy adults and how their blood vessels work. It may help researchers understand normal circulation so they can better compare changes in future conditions.
Bethesda, MarylandAges 18–90 - NCT05395949Enrolling by invitation
Treat breast inflammation with support for mental health
This study looks at a non-surgical (“conservative”) approach to treating granulomatous lobular mastitis, along with help for mental health symptoms. It may help people whose breast inflammation and mental health concerns happen together.
Wuhan, HubeiAges 18–60 - NCT05377268Recruiting

Memory training study for older adults with mild memory problems
This trial tests an approach to improve learning and memory in people age 60+ with amnestic mild cognitive impairment (a specific type of early memory problem). It may help by supporting memory and learning skills, but it also has medication and health-history requirements.

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.
