Randomized Pilot Study of Nicotine for "Hunger Pain" in Patients With Malignant Bowel Obstruction Due to Incurable Cancer
Alternate Title Nicotine in Treating "Hunger Pain" in Patients With Malignant Bowel Obstruction Caused By Cancer
Objectives
Entry Criteria Disease Characteristics:
Prior/Concurrent Therapy:
Patient Characteristics:
Expected Enrollment 20A total of 20 patients will be accrued for this study. Outcomes Primary Outcome(s)Determination of whether ≥ 50% of patients utilize nicotine for treating "hunger pain" ≥ 2 times over a 48-hour period Toxicity as measured by CTCAE v 2.0 Outline This is a randomized, double-blind, placebo-controlled, multicenter, pilot study. Patients are stratified according to vomiting status within the past 24 hours (yes vs no) and use of narcotics (yes vs no). Patients are randomized to 1 of 2 treatment arms.
After 48 hours, patients in arm I may continue nicotine therapy off study. Patients in arm II who are not surgical candidates may cross over to treatment with the nicotine inhaler off study. Blood and spot urine samples are collected at baseline and after 48 hours from patients enrolled at the Mayo Rochester Clinic. Blood samples are analyzed to evaluate circulating hormone (e.g., ghrelin, leptin) concentrations. Urine samples are analyzed to evaluate nicotine and nicotine metabolite concentrations. Global quality of life is assessed at baseline and after 48 hours. "Hunger pain" is assessed at baseline. Trial Lead Organizations Mayo Clinic Cancer Center
Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. |
