Pilot Trial of Sirolimus, Gemcitabine and Cisplatin for Patients With High Risk for Cholangiocarcinoma Recurrence


Rochester, Minn.

Trial status:

Open for Enrollment

Why is this study being done?

PRIMARY OBJECTIVES: I. Assessment of the percentage of patients who are able to complete therapy through 4 and 6 months post-registration. SECONDARY OBJECTIVES: I. To describe the adverse events, rate of dose reductions, and quality of life in these patients. II. To summarize timed endpoints of time-to-recurrence, disease-free survival, overall survival, time to treatment failure, and time until treatment related grade 3+ adverse events. OUTLINE: Patients receive cisplatin intravenously (IV) over 1 hour and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, and sirolimus orally (PO) daily or three times weekly. Treatment repeats every 3 weeks for up to 8 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6 months for up to 5 years.

Note: previous calcineurin inhibitor or previous sirolimus use allowed - Current active other malignancy, except non-melanoma skin cancer or carcinoma-in-situ of the cervix; if there is a history of prior malignancy, they must not be receiving other specific treatment (other than hormonal therapy) for their cancer - Current impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of sirolimus (e.g., active ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection) - Current severely impaired lung function (i.e., forced expiratory volume in 1 second [FEV1] < 1 liter) - Received immunization with attenuated live vaccines =< 7 days prior to study entry or during study period;
