A Clinical Study of T3011 in Combination With Regorafenib in Patients With Advanced Colorectal Cancer

Launched by WEST CHINA HOSPITAL · Dec 27, 2023

ClinConnect Summary

This clinical trial is studying a new treatment for advanced colorectal cancer, a type of cancer that has spread and cannot be removed through surgery. The researchers want to see if a drug called T3011, given through an IV, is safe and effective when combined with another medication called regorafenib, which patients take by mouth. The trial is currently looking for participants aged 18 to 75 who have been diagnosed with advanced colorectal cancer that has not been successfully treated yet. To join the study, participants need to have a measurable tumor and should have already tried at least two other cancer treatments.

If you or a loved one qualifies and decides to participate, you can expect to receive the T3011 and regorafenib while being closely monitored by the research team. They will check for any side effects and how well the treatment is working. It’s important to know that certain health conditions may prevent participation, such as active infections or recent severe heart problems. Overall, this trial aims to explore new options for patients facing advanced colorectal cancer, and your involvement could help contribute to important research in this area.

• • 11. History of allergic reactions attributed to compounds of similar biological composition to HSV-1, IL-12, or anti-PD-1 monoclonal antibody or any excipients for T3011;
• 12. History or evidence of high risk cardiovascular disease, including but not limited to:
• • Severe cardiac rhythm or conduction abnormalities, such as ventricular arrhythmias requiring clinical intervention, II-III degree atrioventricular block, QT interval corrected using the Fridericia formula (QTcF) ≥ 450 msec (male) or ≥ 470 msec (female);
