Boston, MassachusettsAges 18 years+ - NCT06475976Recruiting
Identifying lung types in severe BPD in preemies
This study looks at babies born very early who have severe lung disease (grade 3 BPD) and still need a breathing machine. Researchers will use tests to understand their lung problems better, which may help guide their care.
Philadelphia, PennsylvaniaAges 1 month–1 year - NCT05027919RecruitingPhase 2
Testing ways to predict opioid withdrawal during a taper
This Phase 2 study looks at what opioid withdrawal looks like in the body and whether they can measure it in a meaningful way. You may join if you have an opioid use disorder, can show physical dependence, and are interested in tapering (gradually reducing) opioids under study care.
Baltimore, MarylandAges 18–65 - NCT06444646Recruiting
Studying fat cell particles in obesity
This study looks at tiny particles released from fat tissue in people with and without obesity. It aims to understand differences that might help explain obesity-related health problems.
Genk, LimburgAges 18–65 - NCT06427421Recruiting
Immune cells in children with recent type 1 diabetes
This study looks at immune cells in children who were recently diagnosed with type 1 diabetes. It involves one extra blood draw to better understand how the immune system attacks the pancreas. If you join, no new treatments are given—just observation and analysis of your child's immune cells.
ParisAges 6–18 - NCT06419413Recruiting
Asthma study in Chinese adults to find better treatment matches
This study looks at how asthma affects people in China and tries to find patterns that might help predict which treatments work best. If you have asthma and are between 18 and 75, you may be able to join.
Chengdu, SichuanAges 18–75 - NCT06400550Recruiting
Melanoma metabolism and spread risk study
This study looks at how the body's metabolism might affect the spread of melanoma. Researchers want to see if certain metabolic traits in people with melanoma are linked to a higher risk of the cancer spreading.
Dallas, TexasAges 18 years+ - NCT05597904Recruiting
Study differences in celiac disease and related skin rash
This study looks at why celiac disease (and a related skin condition called dermatitis herpetiformis) can look different from person to person. It may help researchers understand these “phenotypes” (different patterns) so future care can be better targeted.
TampereAges 18 years+ - NCT06383338RecruitingPhase 1
Metabolism Changes in Young People with Lymphoma
This study looks at how your body's metabolism (processing of food and medicine) changes after you start treatment for lymphoma. It uses two safe, commonly used drugs (omeprazole and dextromethorphan) to measure these changes.
Melbourne, VictoriaAges 6–25 - NCT06396312Recruiting
Predicting lithium response in difficult depression
This study looks at how to predict which people with hard-to-treat depression will benefit from adding lithium to their antidepressant. If you have treatment-resistant depression and are considering lithium, this trial may help find the best treatment for you.
Munich, BavariaAges 18 years+ - NCT06361641Recruiting
Study of immune cells in blood cancers
This study looks at immune cells (monocytes) in people with certain blood cancers. Researchers want to understand how these cells behave and change over time. You can join if you are newly diagnosed and haven't started treatment yet.

Studying spinal cord stimulation for chronic low back pain
This study is looking at how people with chronic low back pain respond to spinal cord stimulation (a device that sends gentle electrical pulses to the spine to reduce pain). If you already have a spinal cord stimulator, you may help researchers understand how well it works and how it affects your brain.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 312 recruiting phenotype 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 phenotype 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 phenotype 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.
