Recruiting studies
- NCT03721822RecruitingPhase 1
Imaging how smoking affects lung inflammation in adults
This Phase 1 study uses special lung imaging to measure inflammation after different types of smoking or vaping. It looks at differences between people and may help researchers understand how smoking-related lung irritation develops.
Philadelphia, PennsylvaniaAges 18–45 - NCT07600944Recruiting
Testing a New Insulin Injection in Healthy Volunteers
This study compares how a new insulin aspart injection (a fast-acting insulin) works in the body versus a reference version. Researchers will give a single injection to healthy volunteers and measure how the insulin moves through the bloodstream and affects blood sugar.
Xingtai, HebeiAges 18–55 - NCT06525168RecruitingPhase 1
Safety study of DA414 in healthy volunteers
This trial tests a new medicine called DA414 in healthy people to see if it is safe and how the body processes it. It may help researchers understand the right dose for future studies.
Wuhan, Hubei.ChinaAges 18–45 - NCT06565195RecruitingPhase 1
Study of an experimental treatment for early Parkinson's disease
This study tests an experimental treatment (LY3962681) for people with early Parkinson's. It aims to see if the treatment is safe and can slow the disease. You must have a confirmed diagnosis, be in good overall health, and have stable medication use.
Austin, TexasAges 30–80 - NCT07449572RecruitingPhase 1
Safety study of HT31-1 for healthy volunteers
This trial tests a new drug called HT31-1 to see if it's safe in healthy people. It looks at how the drug moves in your body and if it causes side effects. This is a first step before testing it in patients with ARDS (a serious lung condition).
Richmond, VirginiaAges 18–65 - NCT06714006RecruitingPhase 1
Testing safety of PYC-003 for ADPKD
This study is testing a new investigational medicine called PYC-003 for people with autosomal dominant polycystic kidney disease (ADPKD). It is one of the first studies in humans, so the main goal is to see if the medicine is safe and tolerable. The study is for people with a specific genetic cause (PKD1 mutation) and with certain kidney imaging types.
Southport, Gold CoastAges 18–65 - NCT05443178RecruitingPhase 1
Testing chloroquine added to tuberculosis treatment for safety
This Phase 1 study tests how safe and tolerable chloroquine is when given alongside standard tuberculosis medicine. It mainly involves healthy volunteers and helps researchers understand side effects and safe dosing.
ZurichAges 18–50 - NCT07110519RecruitingEarly Phase 1
PET scan safety study with [18F]-Fluoromannitol in healthy volunteers
This study tests a new radioactive tracer called [18F]-Fluoromannitol for PET scans in healthy adults. It checks how the tracer moves in the body and if it's safe.
Memphis, TennesseeAges 18–75 - NCT07327359RecruitingPhase 1/Phase 2
Study of OLX72021 for male pattern baldness
This trial tests an investigational drug called OLX72021 for male pattern hair loss (androgenetic alopecia). It aims to see if the drug is safe and effective in healthy men with mild to moderate hair loss.
Camberwell, VictoriaAges 18–59 - NCT07182552Enrolling by invitationPhase 1
Testing a new drug NTB003 in healthy volunteers
This early-phase trial tests the safety of a new drug called NTB003 in healthy people. It looks at how the drug moves through the body and affects it, which is a first step toward possibly treating certain conditions.

Common questions
- Are there clinical trials for safety and tolerability in healthy volunteers?
- Yes. Clin2 currently lists 82 recruiting safety and tolerability in healthy volunteers 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 safety and tolerability in healthy volunteers 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 safety and tolerability in healthy volunteers 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.
