About this study
To provide patients with bladder cancer who are scheduled to undergo radical cystectomy with a preoperative high-arginine nutritional supplement. The investigator will measure patient adherence to the regimen, tolerability of the supplement and feasibility of supplementation. Secondary outcome measures will include differences in length of stay and complication rate between groups.
Read the detailed description
The purpose of this study is to investigate the use of a high-arginine protein supplement prior to surgery for patients undergoing radical cystectomy for treatment of bladder cancer. As many as 50% of patients who undergo radical cystectomy experience a postoperative complication, and poor preoperative nutritional status is known to increase the risk of complications. Preoperative use of a high-arginine protein shake has been shown to reduce the risk of postoperative complications for patients undergoing surgery for colon cancer, and this study seeks to determine whether this is also true for patients undergoing radical cystectomy for bladder cancer.
Subjects will drink four protein shakes (Nestle Impact AR) per day for 5-7 days prior to radical cystectomy. Shakes will be provided to patients free of charge. On the date of surgery, subjects will turn in a log of shake consumption. Surgery will then proceed in typical fashion, and no changes will be made to surgery or postoperative care. Clinical outcomes for the first 90 postoperative days will be collected. Patient outcomes will be compared to those of contemporary controls who do not undergo supervised nutritional supplementation. Primary study outcome is to assess safety, tolerability and adherence to supplementation regimen. Secondary outcomes include differences in complication rates and length of postoperative hospital stay between groups.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing high arginine nutritional supplement (Nestle's Impact AR) in people with Bladder Cancer, run by University of Pittsburgh 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 1 inclusion and 1 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 3 Oct 2017. 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 phase mean?
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Safety, tolerability and adherence to supplementation regimen." (time frame: 4 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 NCT02655081, which also lists 11 linked publications.
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 3 Oct 2017.
