Recruiting studies
- NCT05379556Recruiting
Study for long COVID sexual and reproductive symptoms
This study is looking at people who have recovered from COVID-19 but still have ongoing (long COVID) sexual, reproductive, or related symptoms. Researchers want to learn about these lingering problems and what may help, based on your answers and study procedures.
Naples, ItalyAges 18 years+ - NCT06645847Recruiting

New FND treatment program and care pathway
This study is creating a new team-based treatment program for people with functional neurological disorder (FND). It tests whether a coordinated care pathway helps patients get better results from therapy and psychiatry.
Birmingham, AlabamaAges 8–89 - NCT06345781Recruiting
Abdominal electrical stimulation for bowel management in spinal cord injury
This trial tests if a special electrical stimulation (FES) on your belly can help make your bowel routine more predictable and shorter. You'll use electrodes on your skin 30 minutes before your usual bowel program.
Englewood, ColoradoAges 18 years+ - NCT06227962Enrolling by invitation
Thinking and quality of life in retinoblastoma survivors
This study looks at how retinoblastoma and its treatment affect thinking skills and quality of life over time. It may help doctors better support survivors and their families.
Amsterdam, North HollandAges 6 months–35 years - NCT06130176Recruiting
Single-step sinus and dental surgery for tooth-related sinusitis
This trial tests a combined procedure to fix sinus infections caused by tooth problems. If you have chronic sinusitis from a dental issue that hasn't improved with other treatments, this surgery might help by addressing both the tooth and sinus in one operation.
Buraidah, Qassim ProvinceAges 18 years+ - NCT05920824Recruiting
Testing treatment for leaking mitral and tricuspid valves
This trial studies people with atrial fibrillation and moderate-to-severe leakiness in the mitral and tricuspid valves in the heart. It likely aims to improve symptoms and heart function by better addressing how these valve leaks happen.
LondonAges 18 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Birmingham, AlabamaAges 18–60 - NCT05655390Recruiting
Study after a suicide attempt testing a new treatment link
This study looks at how well an approach helps people after a suicide attempt, and how certain measurements in the body and thinking relate to outcomes. You may be able to join if you’re an adult and can safely complete the study assessments.
Barcelona, BarcelonaAges 18 years+ - NCT04704297RecruitingPhase 4
Trigger point shots for low back muscle pain
This trial tests whether injecting sore “trigger points” in low back muscles helps improve chronic low back pain. It compares treatments in people with specific low back muscle pain patterns and excludes several other causes of pain.
Tacoma, WashingtonAges 18 years+ - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.
Wuhan, HubeiAges 18–70 - NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.
ÖrebroAges 18–65 - NCT04733404Recruiting
Dragonfly device study for functional mitral valve leakage
This trial tests a catheter-based procedure (putting a small device through blood vessels) to repair a leaking mitral valve caused by heart muscle problems. It aims to reduce symptoms and improve heart function and safety in people who are still having heart failure symptoms despite standard treatment.
Hangzhou, ZhejiangAges 18 years+ - NCT05359796Recruiting
Study of long-term type 1 diabetes symptoms and characteristics
This study looks at what day-to-day health and medical features are like in people who have had type 1 diabetes for many years. It may help researchers better understand long-term needs in type 1 diabetes and guide future care.
Changsha, HunanAges Any age - NCT05694039Recruiting
Track thinking changes in older adults with hearing loss
This study follows older adults who have age-related hearing loss to see whether wearing hearing aids helps protect thinking and memory over time. You may be included if your hearing loss is the type that hearing aids can usually improve and if your thinking test scores suggest mild cognitive difficulties.
Guangzhou, GuangdongAges 60–85 - NCT05698576Recruiting
Laser treatment through the skin for men with prostate cancer
This trial tests a laser procedure done through the skin between the scrotum and anus, guided by MRI and ultrasound, for men with certain prostate cancer types. It aims to heat and treat prostate cancer while checking safety and outcomes over follow-up visits.
Hialeah, FloridaAges 50–80 - NCT05193136Recruiting
Testing sleep and exercise effects on strength and thinking in lung disease
This trial studies whether improving sleep habits can help people with lung conditions like COPD or IPF maintain muscle strength and thinking (cognitive function). It may help by addressing sleep quality and related health factors, but eligibility depends on your current diagnoses and treatments.
Jōyō, KyotoAges 20 years+ - NCT05821140Recruiting
Assessing jaw and bite function in children with oral health issues
This study looks at how a child’s mouth, jaw, and biting function work in different dental and oral health situations. It may help clinicians better understand what support or treatments children need.
Clermont-FerrandAges 3–17 - NCT04643106Recruiting
Compare two ways to stop bleeding during ovarian cyst removal
This trial compares two methods used during laparoscopic (small-robot/pinch-incision) ovarian cyst surgery to see which stops bleeding better and better protects future fertility. You may be eligible if you’re having surgery for ovarian endometriosis and meet hormone and pregnancy-related requirements.
Goyang-si, Gyeonggi-doAges 19–45 - NCT06089031Recruiting
Belgian registry for coronary function testing
This study collects information from people having tests to check how well the blood vessels in the heart work. It helps doctors learn more about these tests and improve care for future patients.
Deurne, AntwerpAges 18 years+ - NCT06100601Recruiting
Nervous System and Voice Disorder Study
This study looks at how the autonomic nervous system (the part that controls things like heart rate and sweat) might be linked to functional dysphonia, a voice problem with no clear physical cause. If you have this voice disorder and meet the health and lifestyle criteria, your participation could help improve understanding of the condition.
Ghent, East-FlandersAges 18–60 - NCT05985668Recruiting
Better diagnosis for platelet function disorders
This study aims to improve how doctors diagnose platelet function disorders—problems with blood cells that help stop bleeding. If you have a known or suspected platelet disorder and are being seen at Karolinska University Hospital, this trial may offer better testing to find the cause of your bleeding issues.
StockholmAges 1 year+ - NCT07871708Recruiting
Beauty device for skin concerns
This study tests a handheld beauty device that may improve wrinkles, skin firmness, and skin texture. If you have signs of aging or skin texture issues, you might be eligible to try it at no cost.

- How do I know if I qualify for a functionality 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 functionality 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.
