It may help doctors better predict who can benefit from surgical approaches and what outcomes matter most to patients.
UmeåAges 18 years+ - NCT05357378Recruiting
Hip replacement study using a reverse hip implant
This trial looks at how safe and well a specific “reverse” hip implant works in people who need their first total hip replacement. It may help by improving pain and hip function, while closely tracking safety during and after surgery.
Miami, FloridaAges 50–75 - NCT05357794RecruitingPhase 2
Skin-directed radiation plus brentuximab for lymphoma skin disease
This Phase 2 trial studies whether giving very low-dose total-skin electron beam radiation at the same time as brentuximab vedotin can control mycosis fungoides (a lymphoma that affects the skin). It’s for people whose disease has returned or hasn’t responded to prior treatment, especially if the tumor marker CD30 is present.
Houston, TexasAges 18 years+ - NCT05359263RecruitingPhase 2
Dapagliflozin for kidney disease to improve heart structure
This Phase 2 study tests whether dapagliflozin can improve heart structure and function in people with chronic kidney disease (CKD). Dapagliflozin is a kidney-heart medicine that may affect how the heart changes over time, measured by heart scans.
CopenhagenAges 18 years+ - NCT05362760RecruitingPhase 4
Abemaciclib plus hormone therapy, with digital side-effect tracking
This trial tests whether adding abemaciclib to standard hormone (endocrine) therapy can improve outcomes for certain types of advanced breast cancer. It also uses a phone app to help you and the team track side effects so problems can be caught early.
AalenAges 18 years+ - NCT05363059Recruiting
Bariatric surgery compared with standard treatment for metabolic syndrome
This trial compares bariatric (weight-loss) surgery with medical (non-surgery) treatment in people with metabolic syndrome, a cluster of risk factors that can affect heart and blood sugar. It aims to see which approach improves these health risks and overall metabolism.
Chongqing, Chongqing MunicipalityAges 18–65 - NCT05363319Recruiting
Cemiplimab study in adults with advanced lung cancer
This observational study looks at how well cemiplimab works and how safe it is for adults with advanced non-small cell lung cancer in everyday care in Europe. It mainly follows patients already prescribed cemiplimab, and asks them to complete questionnaires.

Common questions
- Are there clinical trials for effectiveness?
- Yes. Clin2 currently lists 6,871 recruiting effectiveness 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 effectiveness 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 effectiveness 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.
