Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the study is the enhancement of analgesia by F13640 when gradually introduced in combination with opioid treatment after 14 days to evaluated by the pourcentage (% of responders) in patients who have failed adaptation of opioid therapy for cancer pain, when administered for 2 weeks including a 7-day titration period.;Secondary Objective: To evaluate if : - F13640 treatment allows decreasing cumulative opioid consumption (opioid saving) and reducing adverse effects whatever the dose administered during the treatment period. - F13640 induces a long lasting analgesic effect after the treatment period and F13640 withdrawal can cause any rebound effect in patients who have failed adaptation of opioid therapy for cancer pain, when administered for 4 weeks including a 7-day titration period. - Other secondary objectives are to assess pain relief, impact on sleep, safety and tolerability on this population during the study period. ;Primary end point(s): Response to the trial defined by a decrease of at least 10 of the average (mean value on the 4 last days) of the 24 hour recall pain intensity VAS score (at rest and mobilization), between inclusion and the end of the first 2-week treatment period (Day 14 or visit of premature withdrawal). Data will be captured on a patient digital assistant (PDA).
