About this study
Official title: Pilot Study of Rapamycin as Treatment for Autosomal Dominant Polycystic Kidney Disease
This study is a prospective, randomized, open-label, pilot clinical trial designed to compare the effects of an agent that has antiproliferative (1,2), antiangiogenesis (3),and tumor-progression blocking capabilities (4), namely, rapamycin (Rapamune®), in the treatment of autosomal-dominant polycystic kidney disease (ADPKD).
Up to this time, only generic renal disease treatments for ADPKD have been in use, such as the treatment of hypertension, urinary tract infections, renal stones, renal call carcinomas, and replacement therapy with dialysis and/or renal transplantation. The fundamental aberrations in ADPKD are proliferation of cyst-forming tubuloepithelial cells, secretion of cytokine-rich fluid into those cysts, and progressive cyst expansion and release of inflammatory mediators that injure surrounding normal renal tissue. Consequently, therapy directed specifically at blocking the proliferation of tubuloepithelial cells and their tendency to malignant transformation, as well as impeding their blood supply, should have obvious merit.

General Procedures:
In Group I participants will have an iothalamate glomerular filtration rate (GFR) equal to or greater than 60 ml/min/1.73 m2, and in Group II participants will have a GFR less than 25-59 ml/min/1.73 m2. Both males and females with ADPKD who volunteer and qualify, will be randomly and prospectively assigned to treatment with rapamycin at either a high or low trough blood level or to standard care (each 1/3 of enrolled patients) for one year. The two treatment groups will receive rapamycin doses aimed at maintaining the 20- to 24-hour trough blood levels at either 2 to 5 ng/mL (low-dose), or greater than 5 to 8 ng/mL (high-dose). These trough levels are in the lower range of levels used when treating renal transplant recipients in whom trough levels are typically maintained between 5 and 15 ng/mL.

Clinical summary

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Rapamune in people with Polycystic Kidney Diseases, run by The Cleveland Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in GFR From Baseline to 12 Months (time frame: From baseline to 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00286156, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Apr 2015.
