Study how cannabis and tobacco affect reaction and feelings
This study tests how cannabis and tobacco—used together or separately—affect your thinking speed, how you feel, and body responses. You may help researchers understand these effects under controlled conditions, which could be useful for safer use and treatment decisions.
Toronto, OntarioAges 19–45 - NCT05508971Recruiting
Personalized tonsil surgery for sleep apnea in children with Down syndrome
This study tests whether a personalized surgical approach can treat moderate to severe obstructive sleep apnea (OSA) in children with Down syndrome. The goal is to improve breathing during sleep and overall sleep health.
Aurora, ColoradoAges 2–17 - NCT05548205Recruiting
Glucose monitoring for people starting insulin after hospital discharge
This study checks whether using a continuous glucose monitor for 2 weeks after you leave the hospital helps you manage blood sugar better when you are newly starting insulin. It may help your care team adjust insulin and track glucose trends more closely right after discharge.
Mineola, New YorkAges 18–100 - NCT05515354RecruitingPhase 4
Smoking quit plan matched to your menstrual cycle phase
This Phase 4 study tests a smoking-quit treatment plan timed to your menstrual cycle. It may help you quit smoking and learn how quitting support works for people who menstruate regularly.
Toronto, OntarioAges 18–40 - NCT05534321RecruitingPhase 1/Phase 2
Preventive radiation for high-risk spinal bone metastases
This trial tests whether preventive (before serious problems happen) radiation to the spine can help people with high-risk, mostly symptom-free bone metastases. It may reduce the chance of pain escalation or dangerous complications from cancer in the spine.
Miami, FloridaAges 18 years+ - NCT05504681Recruiting
Using brain test markers in a cancer clinic visit
This study adds special brain “biomarker” tests into routine visits for adults with brain tumors. It may help the clinic better track these cancers over time and tailor care.
Miami, FloridaAges 18 years+ - NCT05522881Recruiting
Study of genetic changes in oropharyngeal cancer tumors
This study collects information and tumor tissue to look for genetic changes in oropharyngeal cancer, especially in patients whose cancer has come back. The goal is to better understand the disease and may help future treatment planning.
Kaohsiung CityAges 20 years+ - NCT05525663Recruiting
Rehab for older adults after heart failure with strong pumping
This trial studies whether a physical rehabilitation program helps older adults recover and function better after a recent hospital stay for heart failure when the heart’s pumping strength is preserved. It may help you regain walking ability and daily independence after your episode.
Winston-Salem, North CarolinaAges 60 years+ - NCT05524597RecruitingPhase 1
Older adults write about health experiences
This study looks at how writing about your life experiences and health affects outcomes in older adults. If you’re 65 or older and meet health and safety requirements, you may be able to take part.
Los Angeles, CaliforniaAges 65 years+ - NCT05516277Recruiting
Insomnia care study for older adults with PTSD
This study tests a treatment plan for insomnia (trouble sleeping) in older adults who also have post-traumatic stress disorder (PTSD). The goal is to see whether improving sleep also supports heart and metabolic health (such as blood sugar and heart-related measures).
North Hills, CaliforniaAges 50 years+ - NCT05524480Enrolling by invitation
Help Latina women get overdue breast, cervical care
This trial tests an implementation program that helps clinics better provide breast and cervical cancer screening and HPV vaccination to Latina women who are behind on recommended care. It may help you catch up on screening or start HPV vaccination and connect you to low-cost services.
Houston, TexasAges 18–74 - NCT05535192Recruiting
Telehealth strength exercise to help older women during breast cancer chemo
This study tests whether a supervised at-home (telehealth) strength exercise program can help older women stay strong and keep their chemotherapy on schedule. It’s meant for women who are starting chemotherapy for breast cancer with the goal of cure.
Boston, MassachusettsAges 65 years+ - NCT05508464Recruiting
Test targeted radiation to control many metastases safely
This study tests whether a focused, high-precision type of radiation can control many cancer spread-out spots (“metastases”) at the same time, while keeping side effects acceptable. It may help people with many metastases live longer or have better disease control by aiming treatment at every treatable spot.
London, OntarioAges 18 years+ - NCT05507125Recruiting
Study of how inflammatory genes work in hidradenitis
This study looks at how certain body “inflammatory genes” behave in people with hidradenitis suppurativa. It may help researchers understand what drives this condition and how future treatments could be targeted.

Autologous bone and fat injections versus saline for knee OA
This trial compares different knee injections made from your own bone marrow and/or fat, plus platelet-rich plasma (a blood-derived healing factor), against saline (placebo) to treat painful knee osteoarthritis. It aims to see whether these “autologous” injections reduce knee pain and improve function.
Toronto, OntarioAges 30 years+ - NCT05509933RecruitingPhase 3
Budesonide to prevent engraftment syndrome after stem cell transplant
This Phase 3 study tests whether budesonide can prevent “engraftment syndrome” after people receive a hematopoietic (blood-forming) stem cell transplant. If it works, it may reduce complications around the time the new cells start growing and making blood cells.
Detroit, MichiganAges 18–80 - NCT05463120Enrolling by invitation

- Yes. Clin2 currently lists 5,396 recruiting health 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 health 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 health 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.
