Magnesium drip to reduce pain in ICU trauma patients
This trial tests whether a magnesium infusion can better control pain in adults who have serious injuries and need intensive care. It compares magnesium as part of pain treatment to standard pain care to see if pain improves and stays controlled.
Sacramento, CaliforniaAges 18 years+ - NCT04165486RecruitingPhase 1
Test drug safety in adults with multiple system atrophy
This Phase 1 study checks how safe a drug called ION464 is, how the body handles it, and how much of the drug reaches the bloodstream in adults with multiple system atrophy (MSA). It may help researchers find a dosing approach for future treatments for MSA.

Common questions
- Are there clinical trials for placebo - control?
- Yes. Clin2 currently lists 3,962 recruiting placebo - control 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 - control 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 - control 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.
