Brief Summary

This pilot phase I trial studies the side effects and best dose of curcumin when given together with piperine (piperine extract [standardized]) in reducing inflammation for ureteral stent-induced symptoms in patients with cancer. Curcumin is a spice similar to turmeric and works by decreasing the chemical moderators that produce inflammation in the body. Piperine is pepper and works by increasing the amount of curcumin available in the body when taken with curcumin. Giving curcumin together with piperine may reduce inflammation and discomfort from a ureteric stent in older patients with cancer.

Detailed Description


I. To conduct a dose-escalation study with curcumin and piperine to derive a safe, optimal
biological dose of this combination in cancer patients.


I. To describe the grade 2+ toxicities associated with curcumin and piperine. II. To evaluate
quality of life associated with this combination by means of the Mayo Modified Urinary Stent
Symptom Questionnaire (USSQ).


I. To characterize the change in urinary prostaglandin E2 concentrations that occur at
baseline and then after one week of curcumin + piperine.

OUTLINE: This is a dose-escalation study of curcumin.

Patients receive curcumin orally (PO) twice daily (BID) or thrice daily (TID) and piperine
extract (standardized) PO on days 1-7 in the absence of disease progression or unacceptable

After completion of study treatment, patients are followed up at 1 month.
