Summary
The purpose of this study is to determine whether topical nitroglycerin in addition to
5-flourouracil and radiation therapy are effective in the treatment of operable rectal
cancer.
Clinical Details
Official title: Phase I Dose Escalation Trial of Nitroglycerin in Addition to 5-flourouracil and Radiation Therapy for Neo-adjuvant Treatment of Operable Rectal Cancer
Study design: Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Maximum tolerated dose (MTD)
Secondary outcome: Pathological complete response (pCR)
Detailed description:
This is an open label, non-randomized, multi-cohort, dose escalation trial to evaluate the
safety, tolerability, feasibility and maximum tolerated dose (MTD) of topical nitroglycerin
in addition to 5-flourouracil and radiation therapy for neo-adjuvant treatment of, T3-T4 or
clinically node positive, operable rectal cancer.
Patients that would otherwise be eligible for concurrent neo-adjuvant chemotherapy with
continuous infusion 5-FU, for locally advanced operable rectal cancer, will be assigned to 4
sequential cohorts of 4 different dose levels of nitro glycerin patches (0. 2; 0. 4; 0. 6 and
0. 8mg/hr). Each cohort will consist of 3 patients. All patients will receive radiation
therapy, 45-50 Gy in 25-28 fractions to the pelvis along with continuous infusion 5-FU
225mg/M2 for the duration of the radiation therapy. The radiation therapy will be planned
and delivered as per institutional standard of care for the Dallas VAMC radiation oncology
department.
