E.5 End points |
E.5.1 | Primary end point(s) |
For the primary endpoint of the study, only the sensory scale scores will be assessed. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After 6 cycles of chemotherapy (V2 visit) |
|
E.5.2 | Secondary end point(s) |
- Sensory, motor and autonomic scales from QLQ-CIPN20 questionnaire & longitudinal analysis,
- Grade of chemotherapy-induced peripheral neuropathy (NCI-CTCAE v5.0),
- Score of pain by the BPI SF questionnaire, screening of neuropathic pain by the DN4 interview questionnaire and characterization of neuropathic pain by NPSI questionnaire,
- Health-related quality of life (HRQoL) by the QLQ-C30 questionnaire (EORTC) & longitudinal analysis,
- Disease Free Survival, defined as the interval between the date of randomization and the date of cancer relapse (local, regional, metastases, second cancer) or death from any cause, whichever occurs first,
- Overall survival, defined as the interval between the date of randomization and the date of death from any cause,
- Time to treatment failure, defined as the interval between randomization to treatment discontinuation for any reason, including disease progression, treatment toxicity, patient preference, or death,
- Time to HRQoL score deterioration, defined as the interval between randomization and deterioration ≥ 5 points in the HRQoL score as compared to baseline score or death (all causes),
- Quantification of chemotherapy dose reductions following a chemotherapy-induced neuropathy,
- Assessment of adverse events (excluding chemotherapy-induced neuropathies) associated with cancer, anticancer chemotherapy and study treatment (NCI-CTCAE v5.0),
- Cumulative dose of anticancer received by the patients,
- Assessment of glutamate serum level for correlation with CRC TNM score and neuropathy.
