NCT05856305

PHASE2

SCRT in TNT With or Without Chlorophyllin

Sponsor: Tata Memorial Centre

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to see, if addition of chlorophyllin to neoadjuvant Chemo-radiotherapy can reduce the gastro-intestinal/genitourinary/hematological toxicity rates and improve the quality of life in patient's diagnosed with locally advanced rectal cancer. This is a randomized placebo control trial, wherein participants randomized to Chlorophyllin arm will receive the drug of interest along with the standard treatment. Participants randomized to other arm will receive placebo along with the standard treatment. Researchers will compare the difference between the outcomes from both the arms and will also observe the non-operative management success rates.

Inclusion Criteria: * Age \> 18 years. * Histologically confirmed diagnosis of adenocarcinoma of the rectum. * Clinical Stage II/III (T2-3, 4b: adherent to prostate, SV or post vagina but not grossly invading, N0-2) based on MRI. * Non-circumferential tumours with craniocaudal length \<7 cm * The tumours of the lower rectum, or starting up to 7 cm from the anal verge. * No evidence of distant metastases on CT Chest and Abdomen. * No prior pelvic radiation therapy * No prior chemotherapy or surgery for rectal cancer * Eastern Cooperative Oncology Group (ECOG) Performance status 0-2 * Patients must read, agree to, and sign a statement of Informed Consent prior to participation in this study. * Eligible to receive one of the options of standard neoadjuvant chemotherapy as determined by the medical oncologist team. * Absolute neutrophil count (ANC) \> 1.5 cells/mm3, hemoglobin (HGB) \> 8.0 gm/dl, platelet (PLT) \> 150,000/mm3. * Total bilirubin ≤ 1.5 x ULN (except in patients with Gilbert's Syndrome who must have total bilirubin ≤ 3.0 x ULN), aspartate aminotransferase (AST) ≤ 3 x ULN, alanine transaminase (ALT) ≤ 3 x ULN. Exclusion Criteria: * Signet or mucinous histology cancer of rectum * Recurrent rectal cancer or previous pelvic radiotherapy * Primary unresectable rectal cancer. * Creatinine level greater than 1.5 times the upper limit of normal. * Patients who are unable to undergo an MRI. * Patients with a history of any arterial thrombotic event within the past 6 months. This includes angina (stable or unstable), MI, TIA, or CVA. * Ulcerative colitis or any other histologically confirmed inflammatory bowel disease. * Patients with a history of venous thrombotic episodes such as deep venous thrombosis, and pulmonary embolism occurring more than 6 months prior to enrollment may be considered for protocol participation, provided they are on stable doses of anticoagulant therapy. Similarly, patients who are anticoagulated for a trial fibrillation or other conditions may participate, provided they are on stable doses of anticoagulant therapy. * Patients with any other concurrent medical or psychiatric condition or disease which, in the investigator's judgment, would make them inappropriate candidates for entry into this study. * Poor reliability for follow up. * Ineligible as per eligibility criteria
