Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Relapse-Free Survival (RFS) | Up to 5 years | RFS will be defined as the time from randomization to relapse, or death from any cause, whichever occurs first. Patients alive without relapse at the time of the analysis will be censored at the date of last tumour assessment. The Kaplan-Meier approach will be used to estimate median RFS for each study arm. The two-sided log-rank test, stratified on randomization stratification factors, will be used to compare RFS between the investigational arm and the control arm. The stratified Cox-regression (with proportional hazards) will be used to estimate the hazard ratio and to calculate the 95% confidence intervals of the hazard ratio. |
| Secondary | Time to Treatment Failure (TTF) | Up to 1 year | TTF will be defined as the time from the date of randomization to the date of permanent discontinuation of the study treatment, whichever is the cause. Patient not known to have withdrawn treatment before 12 months (study treatment duration) will be censored at the time of treatment stop. TTF survival will be estimated using the Kaplan-Meier method, and will be described in terms of medians along with the associated 2-sided 95% confidence interval for the estimates. |
| Secondary | Overall Survival (OS) | Up to 5 years | OS will be defined as the time from date of randomization to the date of death, from any cause. Patient not known to have died at the time of analysis will be censored based on the last recorded date on which the patient was known to be alive. OS survival will be estimated using the Kaplan-Meier method, and will be described in terms of medians along with the associated 2-sided 95% confidence interval for the estimates. |
| Secondary | Patient's Quality of Life (QoL) | Up to 5 years | The patient's Quality of Life will be assessed using the EORTC QLQ-C30. Scores will be calculated at each time point according to the scoring manuals. Descriptive statistics will be used to evaluate baseline scores and evolution of scores from baseline to each time point (Every 3 months since baseline, then every 4 months after second year surveillance). Data will be compared between arms using the Student's t-test. The QoL data will also be presented graphically if deemed relevant. |
| Secondary | Safety profile | Up to 5 years | The safety will be described mainly on the frequency of adverse events coded using the common toxicity criteria (NCI-CTCAE v5.0) grade. Descriptive statistics will be provided for characterizing and assessing patient tolerance to treatment. Adverse events will be coded according to the MedDRA®. |
| Secondary | Compliance To Treatment | Up to 1 year | The compliance to treatment will be described using the proportion of patients requiring dose reduction and temporary or permanent treatment discontinuation. |
