Recruiting studies
- NCT05428826RecruitingPhase 4
Stopping steroids early if PET/CT looks negative
This study tests whether some people with idiopathic retroperitoneal fibrosis can stop prednisone earlier when a PET/CT scan shows no concerning activity. It may reduce steroid side effects while keeping the disease under control.
Agen, FranceAges 18 years+ - NCT04047576RecruitingPhase 2/Phase 3
Sirolimus for unknown-cause retroperitoneal scarring
This trial tests sirolimus to treat idiopathic (unknown-cause) retroperitoneal fibrosis, a condition where scar tissue forms in the belly behind the kidneys. You may be considered if imaging and blood tests suggest active inflammation, and if you’re able to safely take the study medicine and return for follow-up.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04314323Recruiting
Registry for idiopathic retroperitoneal fibrosis in China
This study is a registry that collects medical information (and sometimes tissue results) from people with retroperitoneal fibrosis that is not caused by another known condition. It may help doctors better understand the disease and improve future care.
Beijing, Beijing MunicipalityAges 18–75 - NCT04312854Recruiting
Study of IRPF in adults in China

Common questions
- Are there clinical trials for idiopathic retroperitoneal fibrosis?
- Yes. Clin2 currently lists 4 recruiting idiopathic retroperitoneal fibrosis 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 idiopathic retroperitoneal fibrosis 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 idiopathic retroperitoneal fibrosis 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.
