Clinical Trial Summary

This is a randomized, double-blind, placebo-controlled, multicenter study. The main purpose of the study is to evaluate the clinical efficacy and safety of nimotuzumab combined with trifluridine/tipiracil in third-line and beyond for the treatment of metastatic colorectal cancer (mCRC). This study planned to be divided into two parts: Part A and Part B. Part A (safety run-in) with a 3 + 3 study design, which primary endpoint is safety; Part B (main study) with a prospective, randomized, double-blind, placebo-controlled design, which primary endpoint is overall survival (OS).

Description:

This is a randomized, double-blind, placebo-controlled, multicenter study. The main purpose of the study is to evaluate the clinical efficacy and safety of nimotuzumab combined with trifluridine/tipiracil in third-line and beyond for the treatment of metastatic colorectal cancer (mCRC). This study planned to be divided into two parts: Part A and Part B. Part A is a dose escalation study, and two dose levels are set up in terms of the dose of nimotuzumab (dose level 1: nimotuzumab 400 mg weekly; dose level 2: nimotuzumab 600 mg weekly), while the dose of trifluridine/tipiracil remains unchanged. The aim of this part is to investigate the safety of combination therapy and ensure the dose of nimotuzumab in Part B. After completed the safety-run-in of Part A, Part B can be started. In Part B (main study), a prospective, randomized, double-blind, placebo-controlled design is proposed. Patients of this part will be stratified by tumor site (left half of colorectal vs right half of colon), age (less than 65 years old vs 65 years old or older) and number of metastases (<3 vs ≥3) and randomly divided into experimental group (nimotuzumab plus trifluridine/tipiracil) and control group (placebo plus trifluridine/tipiracil) at a ratio of 2:1. Treatment will continue until disease progression or intolerable toxicity or withdrawal of consent. In part B, the primary endpoint is overall survival (OS); the secondary endpoint included: Progression free survival (PFS), time to progress (TTP), overall response rate (ORR), disease control rate (DCR), duration of response (DoR), quality of life (QoL), etc.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	tumor-related markers	To explore the influence of tumor-related markers (such as EGFR, p53, etc.) on prognosis.	Up to 18 months
Primary	overall survival (OS)	The primary endpoint is overall survival (OS, defined as from randomization to death due to any cause).	Up to 18 months

The scale assesses symptoms, functionality, and overall health status/life quality. Each item is transformed to a 0-100 scale according to a standardized scoring procedure. Higher scores indicate more severe symptoms, while in the functionality and overall health status/life quality sections, higher scores signify better conditions.	Up to 18 months
Secondary	European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Colorectal Cancer 29 (EORTC-QLQ-CR29)	Quality of Life will also be evaluated by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Colorectal Cancer 29 (EORTC-QLQ-CR29). EORTC-QLQ-CR29 is a supplementary questionnaire module to be employed in conjunction with the Quality of Life Questionnaire Core 30 (QLQ-C30). All of the scales and single-item measures range in score from 0 to 100. A high score for the functional scale and functional single-items represents a high level of functioning, whereas a high score for the symptom scales and symptom single-items represents a high level of symptomatology or problems.

Secondary	Adverse Events	Any untoward or unfavorable medical occurrence in a participant, including any abnormal sign (for example, abnormal physical exam or laboratory finding), symptom, or disease, temporally associated with the participant's participation in the research, whether or not considered related to the participant's participation in the research.
