| Measure | Time frame |
|---|---|
| Main Objective: The objective is to compare the safety and efficacy of masitinib 4.5 mg/kg/day to placebo in the treatment of two different patterns of mood disorders: antidepressant resistant major depression and dysthymic disorder. Efficacy is evaluated using the proportion of responders at week 12. Response is defined as: - 50% improvement in 17-item Hamilton Depression Scale (HAMD-17) - And a maximum value of 17 (corresponding to mild depression) on the HAMD-17 - And Clinical Global Impression-Improvement scale (CGI-I) rating of 1 (?very much improved) or 2 (?much improved?) Safety is assessed through monitoring of adverse events;Secondary Objective: ? Proportion of responders at w4, w8. ? HAMD-17 score every week until w4 and then every 2W until w12 ? Proportion of resmission at w4, w8 and w12. Remission is defined as: - 50% improvement in 17-item Hamilton Depression Scale (HAMD-17) - And a maximum value of 7 (corresponding to no depression) on the HAMD-17 - And Clinical Global Impression-Improvement scale (CGI-I) rating of 1 (?very much improved) or 2 (?much improved?) ? Montgomery-Asberg Depression Rating Scale (MADRS) score at w4, w8, w12 ? Clinical Global Impression-Improvement scale (CGI-I) score every 1W until w4 and then every 2W until w12 ? Clinical Global Impression-Severity scale (CGI-S) score every 1W until w4 and then every 2W until w12 ? Leeds Evaluation Sleeping Questionnaire (LESQ) score at w4, w8, w12 ? Beck Depression Inventory (BDI) score at w4, w8, w12 ? Columbia-Suicide Severity Rating Scale (C-SSRS) score every 1W until w4 and then every 2W until w12;Primary end point(s): Response rate, defined as the proportion of patients with response. Response is defined as: - 50% improvement in 17-item Hamilton Depression Scale (HAMD-17) - and a maximum value of 14 (corresponding to mild depression) on the HAMD-17 - And Clinical Global Impression-Improvement scale (CGI-I) rating of 1 (?very much improved) or 2 (?much improved?);T | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): ? Proportion of resmission. Absolute and relative change from baseline to timepoint for the following variables: - 17-item Hamilton Depression Rating Scale (HAMD-17) score: HAMD-17 is a 17-items test measuring the severity of depression. The score from each item contribute to a total score. HAMD-17 score increases with depression severity. - Montgomery-Asberg Depression Rating Scale (MADRS) score: MADRS is a 10-items scale measuring the depression severity. Each item (symptom) is graded on a scale from 0 to 6 and all the items contribute to a total score. MADRS score increases with depression severity. - Clinical Global Impression-Improvement scale (CGI-I) score: the CGI-I is a 7 point scale to assess how much the patient's illness has improved or worsened compared to a baseline state (1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse). - Clinical Global Impression-Severity scale (CGI-S) score: the CGI-S is a 7-point scale rating the patient's illness based on the clinical experience (1= normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill). - Leeds Evaluation Sleeping Questionnaire (LESQ): the LESQ is a standardized self-reporting instrument comprising ten items. - Beck Depression Inventory (BDI) total score: the BDI is a 21-item self-administered questionnaire intended to assess the existence and severity of symptoms of depression. Each item (symptom) is scored from 0 to 3 and all the items contribute to a total score. BDI score increases with depression severity. - Columbia - Suicide Severity Rating Scale (C-SSRS) score: C-SSRS is a 16-items scale measuring the suicide severity.;Timepoint(s) of evaluation of this end point: week 12 | — |
