Brief Summary:
This study is designed as an international, open-label, controlled two-arm, randomized phase III comparison study evaluating the efficacy and safety of trifluridine/tipiracil in combination with bevacizumab versus trifluridine/tipiracil monotherapy in patients with refractory mCRC.

Condition or disease Intervention/treatment Phase
Refractory Metastatic Colorectal Cancer Drug: Trifluridine/Tipiracil Drug: Bevacizumab Phase 3

Detailed Description:
This is an international, open-label, controlled two-arm, randomised phase III study evaluating the efficacy and safety of trifluridine/tipiracil in combination with bevacizumab versus trifluridine/tipiracil monotherapy in patients with refractory mCRC. The analysis will be done after 331 events are reported. In order to observe this number of events, 490 patients will be randomised (1:1) to receive trifluridine/tipiracil in combination with bevacizumab (experimental arm) or trifluridine/tipiracil monotherapy (control arm).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: From date of randomization to the death due to any cause or cut-ff date, whichever comes first (maximum duration: up to 20 months) ]
    Overall survival defined as the observed time elapsed between the date of randomization and the date of death due to any cause. The primary estimand of interest was defined to assess the effect of the randomized treatments on the survival duration in all participants regardless of whether or not intercurrent events had occurred (treatment policy strategy). Analysis was performed using Kaplan- Meier method.

  2. Survival Probability at 6 Months [ Time Frame: From date of randomization until 6 months post treatment ]
    Overall survival defined as the observed time elapsed between the date of randomization and the date of death due to any cause. The primary estimand of interest was defined to assess the effect of the randomized treatments on the survival duration in all participants regardless of whether or not intercurrent events had occurred (treatment policy strategy). Analysis was performed using Kaplan- Meier method. In this outcome measure, data of survival probability at 6 months was reported.

  3. Survival Probability at 12 Months [ Time Frame: From date of randomization until 12 months post treatment ]
    Overall survival defined as the observed time elapsed between the date of randomization and the date of death due to any cause. The primary estimand of interest was defined to assess the effect of the randomized treatments on the survival duration in all participants regardless of whether or not intercurrent events had occurred (treatment policy strategy). Analysis was performed using Kaplan- Meier method. In this outcome measure, data of survival probability at 12 months was reported.

  4. Survival Probability at 18 Months [ Time Frame: From date of randomization until 18 months post treatment ]
    Overall survival defined as the observed time elapsed between the date of randomization and the date of death due to any cause. The primary estimand of interest was defined to assess the effect of the randomized treatments on the survival duration in all participants regardless of whether or not intercurrent events had occurred (treatment policy strategy). Analysis was performed using Kaplan- Meier method. In this outcome measure, data of survival probability at 18 months was reported.


Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: From randomization to the date of radiological tumour progression or death due to any cause or data cut-off date whichever comes first (i.e., up to 20 months) ]
    PFS was defined as the time elapsed between the date of randomisation and the date of radiological tumour progression as per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by investigator, or death (from any cause), whichever comes first. Progressive Disease (PD) as per RECIST 1.1: at least a 20 percent (%) increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Analysis was performed by Kaplan-Meier method.

  2. Probability of Participants With Progression Free Survival at 3, 6, 9 and 12 Months [ Time Frame: From randomization until 3, 6, 9, and 12 months post treatment ]
    PFS was defined as the time elapsed between the date of randomisation and the date of radiological tumour progression as per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by investigator, or death (from any cause), whichever comes first. Progressive Disease (PD) as per RECIST 1.1: at least a 20 percent (%) increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Analysis was performed by Kaplan-Meier method. In this outcome measure, data of PFS at 3 months was reported.

  3. Overall Response Rate (ORR) [ Time Frame: From the date of randomization to the date of documentation of progression or death due to any cause or data cut-off, whichever occurred first (i.e., up to 20 months) ]
    Objective response was defined as percentage of participants who achieved complete response (CR) or partial response (PR) according to the RECIST version 1.1 and using investigator's tumour assessment. As per RECIST 1.1, CR was defined as disappearance of all target and non-target lesions and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (<) 10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the Baseline sum diameters.

  4. Percentage of Participants With Disease Control [ Time Frame: From randomization to the date of first documented tumor progression, death due to any cause or data cut-off date whichever comes first (i.e., up to 20 months) ]
    Disease control is defined as percentage of participants who achieved CR or PR, or stable disease (SD) as per RECIST 1.1 and using investigator's tumour assessment from the date of randomization to until disease progression or death due to any cause. As per RECIST 1.1, CR: disappearance of all target and non-target lesions and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR: at least a 30% decrease in sum of diameters of target lesions, taking as reference baseline sum diameters. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diameters. PD: at least 20% increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions.

  5. Number of Participants With Treatment-emergent Adverse Events (TEAE) and Treatment-emergent Serious Adverse Events (TESAEs) [ Time Frame: From Baseline up to 30 days after the last dose of study treatments (i.e., up to 19.5 months) ]
    An AE was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily have to have a causal relationship with the treatment. Serious adverse events (SAEs) was any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. TEAEs were defined as AEs that developed, worsened or became serious during the TEAE period (time from the first dose of study treatment up to 30 days after the last dose of study treatment). TEAEs included both SAEs and non-SAEs.
