Clinical Trial Summary

The goal of this type of clinical trial is t to answer the following question: Can the chance of colorectal cancer progressing be lowered by taking a medication, QBECO, before and after surgery? The goal of this study is to find out if this approach is better or worse than the standard of care for your type of cancer. The standard of care is defined as care most people get for metastatic colorectal cancer. There is currently no standard of care drug being given before or after surgery to prevent further spread of your cancer. Participants will be asked to self-inject the study medication before surgery for minimum of 11 days and after surgery for minimum of 41 days. Participants will be followed up every 3 months for 2 years, with a final visit at year 5.


Clinical Trial Description

PERIOP-06 is a multicenter, phase II, blinded, randomized, placebo-controlled trial in adult patients planned to undergo resection of colorectal liver metastases (CRLM) for complete clearance of all visible disease. The investigational product for the study is QBECO. QBECO is a site specific immunomodulator (SSI) designed to promote innate immune responses in the gastrointestinal tract and related organs, including the liver. This trial is motivated by the promising preclinical and clinical data supporting the safety and efficacy of QBECO in attenuating postoperative immunosuppression and the resulting proliferation of cancer. The primary objective of this randomized controlled trial is to determine if QBECO administered perioperatively can improve 2-year Progression-Free Survival in adult patients undergoing resection of CRLMs for complete clearance of metastatic disease. The main secondary objectives will be to: 1. Determine the effect of QBECO on the frequency and kinetics of clearance (and recurrence) of circulating tumor DNA (ctDNA) in the postoperative period and further evaluate the use ctDNA as part of ongoing surveillance. 2. Determine the side-effect profile of perioperative QBECO. 3. Determine the effect of QBECO on 5-year overall survival Approximately 115 participants will be randomized to receive a placebo or the investigational product, QBECO. QBECO or placebo will be administered according to the following regimen: 0.1mL subcutaneous injections every two days for 11-120 days preoperatively, and 41 days postoperatively. Participants will be followed for 5 years after surgery. ;
