SCRT в TNT с хлорофиллином или без него (SCOTCH)
Краткосрочный курс лучевой терапии на основе общей неоадъювантной терапии с хлорофиллином или без него (исследование SCOTCH)
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.

Подробное описание
The current standard treatment for locally advanced rectal cancer includes neoadjuvant (treatment given before Surgery) radiotherapy & chemotherapy followed by surgery if needed or wait and watch in patients whom tumour has completely regressed. It has been observed that even after receiving this intensive treatment patients, almost 70% of patients develop acute toxicity (during or within 3 months) of grade 2 or higher (needing medication for toxicity). This affects their treatment tolerance, completion and quality of life.
In this study Researchers are going to see if addition of drug Chlorophyllin (derived from green plant leaves) along with standard treatment would help in reducing the acute toxicity. Chlorophyllin is present in all green leaves of plants giving them green color. The drug is derived from green plant leaves. As it is a plant-based product it is safe for humans and has no known side effects of its own. This is a randomized study which has two arms; Arm 1 is test arm where participants will receive drug of interest (Chlorophyllin) and in other arm participants will receive Placebo. Upon successful completion of study, outcomes from both the study arm will be compared and participants will be followed by standard protocol for 3 years.
