Treatment for tremors in kidney-pancreas transplant recipients
Official title: Conversion From Immediate Release Tacrolimus to Envarsus XR® in Simultaneous Pancreas-Kidney Recipients: Assessment of Functional, Safety and Quality of Life Outcomes (CIRTEN SPK)
Run by University of Wisconsin, Madison · NCT03769298 · Data updated 2026-11-12
This study is testing if a new medication called EnvarsusXR® can help reduce tremors in people who have received kidney-pancreas transplants within the last 3 to 5 years.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-70 who have a history of diabetes and received a simultaneous kidney-pancreas transplant within the last 3 to 60 months.
✕Probably not a fit
Patients who had tremors prior to transplantation or are on an extended-release tacrolimus regimen may not benefit from this study.

What this trial studies
This Phase II/III clinical trial investigates the effects of EnvarsusXR® on tremor severity in patients who have received simultaneous kidney-pancreas transplants. The study will enroll 20 participants who experienced tremors following their transplant, with a focus on those who received their transplant between 3 months and 5 years prior. Participants will be followed for at least one year after conversion from immediate-release tacrolimus to EnvarsusXR®, and outcomes will be compared to historical controls to assess efficacy. The primary endpoints include improvements in tremor severity and quality of life assessments.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce tremor severity and improve quality of life for kidney-pancreas transplant recipients.
How similar studies have gone: While this approach is novel in the context of simultaneous kidney-pancreas transplant recipients, similar studies have shown promise in managing tremors with different treatments.
