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 3 different dose levels of nitro glycerin patches (0.2; 0.4; and 0.6 mg/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.

Intervention / Treatment |

EXPERIMENTAL: Nitroglycerin
Dose escalation trial of Nitroglycerin
|
0.2mg/hr nitroglycerin transdermal patch daily.
The first 3 patients will have a low dose patch applied (0.2 mg/hr).
0.4mg/hr nitroglycerin transdermal patch daily.
The first 3 patients will have a low dose patch applied (0.2 mg/hr) if this is well tolerated a higher dose patch (0.4mg/hr) will be used for the next 3 patients.
0.6mg/hr nitroglycerin transdermal patch daily.
The first 3 patients will have a low dose patch applied (0.2 mg/hr) if this is well tolerated a higher dose patch (0.4mg/hr) will be used for the next 3 patients and if this is well tolerated an even higher dose patch (0.6mg/hr) will be used.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Number of Participants Experiencing Dose Limiting Toxicities (DLT)
Time Frame: Up to 4-6 weeks for each dosing cohort
|
DLT was defined as greater or equal to two instances of grade 3 toxicity, or a single event of grade 4-5 toxicity deemed probably or definitely related to the addition of transdermal neoadjuvant chemoradiation to the standard neoadjuvant chemoradiation
|
Up to 4-6 weeks for each dosing cohort
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With a Pathological Complete Response (pCR)
Time Frame: Time of surgery (~ 6-9 wks) following the completion of neoadjuvant therapy
|
pathological complete response (pCR) at time of surgery following the completion of neoadjuvant therapy. This will be compared to the institutional historical pCR rate. Pathologic complete response indicates a complete absence of cancer at the time of surgical resection. |
Time of surgery (~ 6-9 wks) following the completion of neoadjuvant therapy
