Hong KongAges 35–65 - NCT05640843Recruiting
Plant-based diet study for MGUS or smoldering myeloma
This trial tests whether a whole-food, plant-based eating pattern—plus supplements or placebo—can improve health outcomes in people with MGUS or smoldering multiple myeloma. You may be asked to follow specific recipes and stop certain supplements, so it helps to confirm you can stick with the plan.
Atlanta, GeorgiaAges 18 years+ - NCT05642156Recruiting
Ultrafiltration versus usual dialysis in people on hemodialysis
This study compares a specific way of removing fluid during dialysis (isolated ultrafiltration) with conventional hemodialysis. It aims to see how each approach affects blood flow and fluid shifts in people with end-stage kidney disease.

Common questions
- Are there clinical trials studying Comparator?
- Yes. Clin2 currently lists 1,754 recruiting studies that include Comparator, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Comparator trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Comparator an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Comparator or a specific trial is right for you.
