E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of patients alive 6 months after the beginning of treatment |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
6 months after beginning of treatment |
|
E.5.2 | Secondary end point(s) |
- The objective response is measured every 8 weeks by morphological examination (MRI or thoracic-abdominal-pelvic and cerebral CT scans) based the RECIST criteria v.1.1 - The response duration is calculated from the first objective response until progression or death - Disease control rate is the sum of objective response rate (complete response rate + partial response rate) and stable disease - Progression-free survival is calculated from the 1st administration of the treatment until progression, as defined by the RECIST criteria v.1.1 - The toxicity of the treatments is measured by the frequency and the severity of the adverse events, serious or not, at each official patient visit and at each post treatment follow-up visit using the CTCAE Version 4.03 depending on the actual treatment received (with or without bevacizumab). - The best biochemical response on each marker (LDH, NSE and CgA) is calculated between the start of the treatment and the lowest level occurring during chemotherapy. Biochemical response is defined as the normalization or the decrease of the levels by more than 50% compared to pre-treatment values. |
