Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | disease control rate (DCR), measured in months | 12 months | DCR will be defined as complete response (CR)/partial response (PR)/ stable disease (SD) using RECIST v1.1. Chi2 or Fisher's exact tests will be employed to explore whether there is an association between low or high mutations and DCR. Logistic regression will be employed to produce odds ratios (ORs) and 95% confidence intervals (CIs). |
| Secondary | progression free survival (PFS), measured in months | 12 months | PFS will be measured from start of treatment to date of progression or death from any cause.Logistic regression will be employed to produce odds ratios (ORs) and 95% confidence intervals (CIs). The PFS will be estimated using the Kaplan-Meier method and survival curves will be generated for each group. The log-rank test will be used to compare the survival curves and a Cox proportional hazards model will be fitted to obtain hazard ratios (HRs) and 95% CIs. The proportional hazards assumption will be tested with the use of Schoenfeld residuals |
| Secondary | overall survival (OS), measured in months | 12 months | OS will be defined as time from start of treatment to death of any cause. Logistic regression will be employed to produce odds ratios (ORs) and 95% confidence intervals (CIs). The OS will be estimated using the Kaplan-Meier method and survival curves will be generated for each group. The log-rank test will be used to compare the survival curves and a Cox proportional hazards model will be fitted to obtain hazard ratios (HRs) and 95% CIs. The proportional hazards assumption will be tested with the use of Schoenfeld residuals |
| Secondary | Median values of volume transfer constant (Ktrans) and enhancing fraction (EF) and their product KEF (product of summarised median values of Ktrans x EF/100) will be compared at baseline and on day 15 | 15 days | Dynamic contrast enhance magnetic resonance imaging (DCE-MRI) will be performed pre-treatment and at day 15. KEF changes of more than 70% between the two time points will be considered significant and patients will be thus stratified in two groups, i.e. A) drop in KEF of \>70% and B) less than 70% drop in KEF. |
