QL1203 combined with chemotherapy for metastatic colorectal cancer

A Randomized, Multicenter, Phase 3 Study to Compare the Efficacy and Safety of QL1203 and Placebo Respectively Combined With Chemotherapy in Patients With Metastatic Colorectal Cancer

Phase 3 Interventional Qilu Pharmaceutical Co., Ltd. · NCT04233151

This study is testing if adding a new treatment called QL1203 to standard chemotherapy can help people with metastatic colorectal cancer feel better compared to those who only receive chemotherapy.

What this trial studies

This study evaluates the efficacy and safety of QL1203 when used alongside the mFOLFOX6 chemotherapy regimen compared to a placebo with the same chemotherapy in patients with metastatic colorectal cancer. It is a randomized, double-blind, placebo-controlled, multi-center Phase III trial aiming to enroll 590 patients who have not received prior treatment for their condition. Participants will be assigned to either the QL1203 group or the placebo group in a 2:1 ratio, allowing for a robust comparison of treatment effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with untreated wild-type RAS metastatic colorectal cancer who are not suitable for local treatment.

Not a fit: Patients who have previously received systemic or local chemotherapy for colorectal cancer or those with central nervous system metastases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with metastatic colorectal cancer.

How similar studies have performed: Other studies have shown promise with similar combination therapies, but the specific use of QL1203 in this context is novel.
