Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-Free Survival (Site Read, Investigator Assessment) | Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis, assessed up to 50 weeks | PFS is the time from randomisation until the date of objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) or death (by any cause in the absence of progression). Progression is defined using RECIST (v1.1), as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. |
| Median Progression-Free Survival (Site Read, Investigator Assessment) | Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis, assessed up to 50 weeks | PFS is the time from randomisation until the date of objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) or death (by any cause in the absence of progression).
