Colorectal Metastasis Prevention International Trial 2

Summary

The short perioperative period (days to weeks around surgery) is characterized by stress-inflammatory responses, including catecholamines (CAs, e.g., adrenaline) and prostaglandins (PGs, e.g., prostaglandin-E2) release, and induce deleterious pro-metastatic effects. Animal studies implicated excess perioperative release of CAs and PGs in facilitating cancer progression by affecting the malignant tissue, its local environment, and anti-metastatic immune functions. Congruently, animal studies conducted by the investigators indicate that combined use of the beta-adrenergic blocker, propranolol, and the prostaglandins inhibitor, etodolac - but neither drug separately - efficiently prevented post-operative metastatic development. Two recently conducted clinical trials, conducted by the investigators, in three medical centers in Israel, recruiting breast (n=38) and colorectal (n=34) cancer patients, assessing the safety and short-term efficacy of perioperative propranolol and etodolac treatment. Drugs were well tolerated, without severe adverse events. Importantly, molecular/biological analyses of the excised primary tumor indicated that drug treatment caused promising anti-metastatic transformations, as well as improvements in immune and inflammatory indices. These included (i) decreased tumor cell capacity to migrate, (ii) reduced pro-metastatic capacity of the malignant tissue, and (iii) improvement in immune infiltrating into the tumor (Paper published in Clinical Cancer Research, 2017). Herein, the investigators propose to conduct a double-blind placebo-controlled two-arm Phase II clinical trial in 200 colorectal cancer patients undergoing curative surgery in Israel. A perioperative 20-day drug treatment will be initiated 5 days before surgery. Primary outcomes will include (i) 3-year disease-free-survival (DFS), and 5-year overall survival (OS); and (ii) biological markers in blood samples, and in the excised tumor tissue. Secondary outcomes will include safety indices and psychological measures of depression, anxiety, distress, and fatigue
