Clinical Trial 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.

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tumor assessments should continue regardless of whether patients start a new anti-cancer therapy, unless consent is withdrawn. All patients will be followed for survival unless consent is withdrawn.

Intervention

Drug:
• Trifluridine Tipiracil
Trifluridine-Tipiracil will be administered at 35 mg per square meter orally twice daily, with a glass of water within 1 hour after completion of morning and evening meals, 5 days a week, with 2 days of rest, for 2 weeks, followed by a 14-day rest period. One treatment cycle with Trifluridine-Tipiracil consists of the following: Days 1-5: Trifluridine / Tipiracil (35 mg/m2/dose) orally twice daily Days 6-7: Rest Days 8-12: Trifluridine / Tipiracil(35mg/m²/dose) orally twice daily Days 13-28: Rest
• Panitumumab 20 MG/1 ML Intravenous Solution [VECTIBIX]
Panitumumab will be administered as a 6 mg/kg intravenous infusion over 60 minutes every 2 weeks (q2w) of a 28-day cycle (Day 1 and Day 15).
