Study how THC affects men and women who have used cannabis before

TRX-100 safety and how food affects it in healthy adults
This early-stage study tests a new drug called TRX-100 in healthy volunteers to see if it's safe and how the body processes it, especially when taken with food. The trial helps researchers understand the drug's basic safety profile before testing it in people with medical conditions.
Randwick, New South WalesAges 18–65 - NCT07740772Recruiting
Recovery room care after surgery
This study compares two types of care after surgery: the post-anesthesia care unit (PACU) and the high care unit (HCU). The goal is to see which one helps patients recover better after elective (planned) surgery.
Jakarta Pusat, Jakarta Special Capital RegionAges 18 years+ - NCT02573753Recruiting
Study how sleep affects gut bacteria and health
This study looks at how different sleep patterns change the microorganisms in your gut (gut bacteria) and what that may mean for health. It’s mainly for people who can take part in other approved research studies at the same time.
Rochester, MinnesotaAges 18 years+ - NCT02392442Enrolling by invitationPhase 2
Study drug-free lung irritation using endotoxin in healthy adults
This trial tests how putting a small amount of endotoxin into a specific part of the lung affects the body. It’s designed for healthy, nonsmoking adults, and may help researchers understand lung and immune responses.
Bethesda, MarylandAges 18–45 - NCT07743073Recruiting
Ceylon cinnamon for diabetic nerve pain
This study tests whether taking Ceylon cinnamon daily can help lower blood sugar, improve cholesterol, and reduce nerve pain in adults with type 2 diabetes and painful diabetic peripheral neuropathy. If you qualify, you might get a natural supplement that could ease your symptoms.
AmmanAges 18 years+ - NCT07743294Recruiting
Exercise before breast cancer surgery to reduce arm swelling

TaipeiAges 20 years+ - NCT02391519Recruiting
Study how high altitude affects body energy signaling

Low-oxygen breathing to improve leg movement after spinal injury
This study tests whether breathing brief, mild low-oxygen air (under supervision) can improve leg mobility in people with a certain type of spinal cord injury. It may help with regaining movement, especially if you can already move your legs voluntarily but still have mobility limits.

Common questions
- Are there clinical trials for effectiveness?
- Yes. Clin2 currently lists 6,360 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.
