Study of HIV treatment with long-acting injected medicines
This study follows adults with well-controlled HIV who are planning to switch to a long-acting HIV medicine given as injections. It may help researchers understand how this approach works for people already stable on current treatment.
MilanAges 18 years+ - 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 - NCT05698446Recruiting
Compare ankle surgery options for lateral ankle instability
This study compares different surgical techniques to treat ongoing (chronic) pain and instability on the outside of the ankle. If you qualify, your care team will determine which surgery approach best fits your situation and then track your outcomes.
BeijingAges 18–60 - NCT05727540Recruiting
Cohort study of people with uveitis
This study follows people who have been diagnosed with uveitis (inflammation inside the eye). It helps researchers better understand the condition and how people do over time.
Guangzhou, GuangdongAges 18–90 - NCT05734287Recruiting
Study of causes of high male-hormone signs in young women
This study looks at how common polycystic ovary syndrome (PCOS) is among young women who have “high male-hormone” symptoms. It may help doctors better understand what condition is most likely behind those symptoms in your age group.
DohaAges 15–35 - NCT05738083Recruiting
Study builds prediction tools after aneurysm bleeding
This study looks at early test results and brain scans to predict outcomes after an aneurysm causes subarachnoid hemorrhage. It mainly collects information to build a risk prediction model, which may help doctors plan care more effectively in the future.

Review of extreme breast radiation schedules in Brazil
This study looks back at medical records to understand outcomes when breast cancer patients get a very short course of radiation after surgery. It may help doctors learn whether this “extreme hypofractionation” schedule is safe and effective for more patients.
Fortaleza, CearáAges 18 years+ - NCT05784038Recruiting
Study of monkeypox infection in Brazil
This is an observational study that follows people with confirmed monkeypox (mpox) to better understand the illness over time. It may help doctors learn what to expect and improve care, but it does not test a new treatment.
Belém, ParáAges 18 years+ - NCT05802251Recruiting
Ultrasound measurements to predict bleeding risk in placenta previa
This study uses special ultrasound measurements to estimate the chance of bleeding before delivery in people who have placenta previa but no symptoms. The goal is to help clinicians better predict risk and plan care.
CairoAges Any age - NCT05835739Recruiting
Study of breast cancer prevention in BRCA1/2 mutation carriers
This is an observational study that looks at how different cancer prevention approaches affect women with harmful (deleterious) BRCA1 or BRCA2 mutations. It may help improve future prevention and follow-up plans for women at higher inherited risk.

Testing add-on treatment to calm artery inflammation after heart procedures
This study looks at whether a comprehensive add-on treatment—starting with immune medicine and then a heart procedure when needed—can improve outcomes for people whose coronary artery disease is getting worse quickly. It focuses on cases where inflammation is likely driving new artery blockages or worsening chest pain.

Common questions
- Are there clinical trials for cohort studies?
- Yes. Clin2 currently lists 571 recruiting cohort studies 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 cohort studies 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 cohort studies 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.
