- Registration Number
- NCT05468892
- Lead Sponsor
- University of Campania "Luigi Vanvitelli"
- Brief Summary
This is a randomized phase II, open label, two arm study, evaluating the efficacy of panitumumab in combination with Trifluridine-Tipiracilas third line therapy, after a first line containing an anti-EGFR agent panitumumab(at least 70% of study population) or cetuximab in metastatic colorectal cancer (mCRC) patients.
- Detailed Description
This is a randomized phase II, open label, two arm study, evaluating the efficacy of panitumumab in combination with Trifluridine-Tipiracilas third line therapy, after a first line containing an anti-EGFR agent panitumumab(at least 70% of study population) or cetuximab. The primary objective is to evaluate the efficacy \[as defined by progression free survival (PFS)\] of panitumumab in combination with Trifluridine-Tipiracil in pretreated mCRC patients. The secondary objective is to evaluate the objective response rate (ORR), overall survival (OS) and safety. Patients will be randomized in a 1:1 ratio to receive:
Arm A: Trifluridine-Tipiracil Arm B: Panitumumab + Trifluridine-Tipiracil A total of 112 patients will be enrolled. Treatment will be administered in 28-days cycles until disease progression, unacceptable toxicity, withdrawal of consent or death due to any cause.
All patients will be closely monitored for safety and tolerability during all cycles of therapy, at the treatment discontinuation visit, and during the follow-up period. The National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 (v. 5.0) will be used to characterize the toxicity profile of the study treatments on all patients. Patients who discontinue treatment for reasons other than disease progression (e.g., toxicity) will continue scheduled tumor assessments until disease progression, withdrawal of consent, study termination by Sponsor, or death, whichever occurs first. In the absence of disease progression, tumor assessments should continue regardless of whether patients start a new anti-cancer therapy, unless consent is withdrawn. All patients will be followed for survival unless consent is withdrawn.

- Primary Outcome Measures
Name Time Method PFS from screening up to 30 months PFS: defined as the time from randomization to the earliest documented disease progression or death due to any cause of panitumumab in combination with Trifluridine-Tipiracil vs Trifluridine-Tipiracil"
- Secondary Outcome Measures
Name Time Method ORR from screening up to 30 months ORR: per the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1 (v1.1), defined as the number of patients achieving an overall best response of complete or partial response divided by the total number of patients
Safety and tolerability analysis: defined as the evaluation of incidence and severity of AEs, graded according to NCI- CTCAE, version 5.0 (v. 5.0). from screening up to 30 months To explore the safety and tolerability of panitumumab in combination with Trifluridine-Tipiracil vs standard third line therapy (Trifluridine-Tipiracil)
OS from screening up to 30 months OS: defined as the time from randomization to death due to any cause of panitumumab in combination with Trifluridine-Tipiracil vs Trifluridine-Tipiracil
