Phase II Study of Active Intralymphatic Immunotherapy With Interferon Alfa-Treated Allogeneic Tumor Cells Plus Sargramostim (GM-CSF) and Cyclophosphamide in Patients With Advanced Pancreatic Adenocarcinoma (Summary Last Modified 06/2001)
Alternate Title Vaccine Therapy, Chemotherapy, and GM-CSF in Treating Patients With Advanced Pancreatic Cancer
Objectives I. Determine the feasibility, toxicity, and antitumor effects of active specific intralymphatic immunotherapy with allogeneic pancreatic cancer cells treated with interferon alfa plus low-dose adjuvant systemic sargramostim (GM-CSF) and cyclophosphamide in patients with incurable pancreatic adenocarcinoma. II. Assess the immunologic and biologic correlates of this treatment regimen in these patients. Entry Criteria Disease Characteristics: Histologically confirmed adenocarcinoma of the pancreas that is locoregionally active or metastatic and not amenable to cure or long-term control by surgery, radiotherapy, or chemotherapy No brain metastases refractory to irradiation or surgery Prior/Concurrent Therapy: Biologic therapy: Not specified Chemotherapy: See Disease Characteristics At least 4 weeks since prior chemotherapy Endocrine therapy: No concurrent chronic steroid therapy Radiotherapy: See Disease Characteristics At least 4 weeks since prior radiotherapy Surgery: See Disease Characteristics Other: At least 4 weeks since other prior therapy Patient Characteristics: Age: 18 and over Performance status: ECOG 0-3 OR Karnofsky 60-100% Life expectancy: At least 3 months Hematopoietic: Not specified Hepatic: Not specified Renal: Not specified Cardiovascular: No prior or concurrent significant cardiovascular disease Pulmonary: No prior or concurrent significant pulmonary disease Other: No AIDS HIV negative No prior or concurrent autoimmune disease No other concurrent major medical illness Not pregnant or nursing Fertile patients must use effective contraception Expected Enrollment A total of 14 patients will be accrued for this study. Outline Cultured allogeneic pancreatic cancer cells are incubated with interferon alfa for 72-96 hours. Autologous cell lines, if established, may be used as an alternative. The cells are irradiated immediately prior to use. Patients receive cyclophosphamide IV on day -3 and sargramostim (GM-CSF) subcutaneously on days 0-8. On day 0, patients receive viable tumor cells via dorsal pedal lymphatic cannulation. Treatment repeats every 2-4 weeks for a minimum of 8 weeks in the absence of disease progression or unacceptable toxicity. Patients are followed every 2-4 months.

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. |
