Azithromycin for young children with asthma-like hospital symptoms
This trial tests whether the antibiotic azithromycin can help children in the hospital who are having asthma-like breathing symptoms. If you qualify, your child may get azithromycin as part of the study and will be monitored closely for side effects and breathing improvement.
Gentofte MunicipalityAges 1 year–5.9 years - NCT05035342RecruitingPhase 3
Fecal transplant to clear resistant gut bacteria
This Phase 3 study tests whether a fecal microbiota transplant (FMT) can eliminate hard-to-treat bacteria in the gut, such as ESBL or carbapenem-resistant bacteria. If it works, it may reduce future infections and antibiotic-resistant illness.
ClichyAges 18–105 - NCT05038462Recruiting
Fetal care study for babies with slow growth
This study looks at therapies meant to support brain development in babies whose growth is slower than expected before birth. It enrolls pregnancies in a specific time window and uses ultrasound/Doppler testing to make sure the baby is not likely needing delivery immediately.
BarcelonaAges 18 years+ - NCT05040204RecruitingPhase 1
Test supplements to change how sugars attach to blood proteins
This early (Phase 1) study tests how adding specific dietary supplements affects “protein glycosylation,” which means how sugar molecules attach to proteins in your blood. It’s meant to see how the supplements change these blood measurements and whether the approach is tolerable in generally healthy adults.
Sacramento, CaliforniaAges 18–45 - NCT05043116RecruitingPhase 2
Vitamin D for preventing asthma-like flare-ups in young children
This study tests whether a high-dose vitamin D supplement can help preschool children have fewer acute asthma-like symptoms (coughing, wheezing, or trouble breathing) that require hospital care. It may help by supporting the immune and airway system, but you can only join if the child meets several safety and treatment criteria.
Gentofte Municipality, GentofteAges 1 year–5.9 years - NCT05049057RecruitingPhase 2
Testing a nerve-blocking shot for recent mild TBI
This Phase 2 study tests a medication that blocks a pain signal (a CGRP receptor antibody) in people who recently had a mild traumatic brain injury (mTBI) and are also dealing with post-traumatic headache (PTH). The goal is to see if it can reduce symptoms and improve recovery after the injury.
Fort Bragg, North CarolinaAges 18–50 - NCT05052541RecruitingPhase 3

Early treatment trial for early schizophrenia warning signs
This Phase 2 study tests an NMDA-enhancer medicine to see if it can help people who are in the early “prodromal” stage—when symptoms are starting but full schizophrenia is not diagnosed yet. It aims to reduce or prevent worsening symptoms over the study period.
TaichungAges 13–45 - NCT05057806RecruitingEarly Phase 1
Testing how ketones may affect heart benefits in type 2 diabetes

San Antonio, TexasAges 18–80 - NCT05058287RecruitingPhase 3
Steroid shot during low-back surgery

New York, New YorkAges 18–85 - NCT05058612RecruitingPhase 4
Midodrine to reduce drip medicines in ICU patients
This trial studies whether midodrine can help some ICU patients need less (or stop) a blood-pressure “drip” called vasopressors earlier. It’s meant to see if starting midodrine sooner can speed recovery and reduce how long you need these medicines.
Edmonton, AlbertaAges 18 years+ - NCT05061368RecruitingPhase 2
Sildenafil by mouth to improve breathing in COPD
This Phase 2 trial tests whether sildenafil tablets can improve exercise ability, shortness of breath, and heart-lung function in people with COPD. It also compares against people without COPD to better understand how sildenafil affects breathing tests.
Edmonton, AlbertaAges 40–80 - NCT05063149RecruitingPhase 3
Preemie immune treatment to prevent lung infections and wheezing
This study tests whether a bacterial “lysate” medicine, given to preterm babies, can reduce respiratory (lung) infections and wheezing. It may help protect babies’ airways during the vulnerable first months after birth.

Common questions
- Are there clinical trials for placebo?
- Yes. Clin2 currently lists 5,245 recruiting placebo 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 placebo 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 placebo 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.
