Brief Summary:

Primary Objective:

To assess the efficacy of SAR292833 versus placebo in reducing pain intensity associated with chronic peripheral neuropathic pain using 11-point numerical rating scale (NRS).

Secondary Objectives:

  • To compare the effects of SAR292833 with placebo on the change of neuropathic pain symptoms versus baseline Neuropathic Pain Symptoms Inventory (NPSI);
  • To evaluate the effects of SAR292833 in comparison to placebo on the change in pain intensity of mechanical allodynia;
  • To investigate the safety and tolerability of SAR292833 in comparison to placebo;
  • To investigate the pharmacokinetics (PK) and the relationships between main efficacy parameters or pharmacodynamic effect (PD) and pharmacokinetics (PK/PD) of SAR292833 in patients with chronic peripheral neuropathic pain.

Condition or disease Intervention/treatment Phase

Actual Enrollment : 191 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)

Study Start Date : March 2012
Actual Primary Completion Date : May 2013
Actual Study Completion Date : May 2013

Arm Intervention/treatment
Experimental: SAR292833 dose level 1
Dose level 1 twice daily immediately after breakfast/dinner
Drug: SAR292833

Pharmaceutical form: capsule

Route of administration: oral

Experimental: SAR292833 dose level 2
Dose level 2 twice daily immediately after breakfast/dinner
Drug: SAR292833

Pharmaceutical form: capsule

Route of administration: oral

Placebo Comparator: Placebo
Placebo (for SAR292833) twice daily immediately after breakfast/dinner
Drug: placebo

Pharmaceutical form:capsule

Route of administration: oral

Primary Outcome Measures :
  1. Change from baseline in the average daily pain intensity as measured by the 11-point NRS; [ Time Frame: Baseline to 4 weeks ]
    The average daily pain intensity is the mean of the last consecutive 7 days.

Secondary Outcome Measures :
  1. Percentage of patients with reduction in pain intensity of at least 30% and 50% at endpoint compared to baseline derived from the primary efficacy endpoint; [ Time Frame: Baseline to 4 weeks ]
  2. Change in Neuropathic Pain Symptom Inventory (NPSI) after 4 weeks treatment compared to baseline [ Time Frame: Baseline to 4 weeks ]
  3. Change in intensity of the mechanical allodynia after 4 weeks treatment compared to baseline using visual analog scale (VAS) [ Time Frame: Baseline to 4 weeks ]
  4. Amount of and time to first rescue medication intake during the treatment period. [ Time Frame: 4 weeks ]
  5. Change in Daily Sleep Interference Score (DSIS), clinical global impression of change (PGIC and CGIC). [ Time Frame: 4 weeks ]

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria:

-The study will include adult patients of either gender, 18 - 85 of age, who have signed the informed consent form, and presenting with chronic peripheral neuropathic pain associated with: diabetic polyneuropathy, post-herpetic neuralgia.

  • The neuropathic pain must have a distinct neuroanatomically plausible distribution with sensory signs and symptoms confirmed by DN4 (Douleur Neuropathique en 4 questions) score of ≥4 and being present for more than 3 months.
  • SAR292833 should be taken in fed condition. Therefore, only patients who were judged to be reliable to fulfill this condition (used to having breakfast and dinner) will be included in the study.

Exclusion criteria:

  • Patients with a baseline average daily pain intensity for their neuropathic pain < 5 on the 11-point NRS over the last 7 days before randomization;
  • Patients with a pain intensity of ≥ 9 on the 11-point NRS at Visit 1;
  • Any pain other than the neuropathic pain of equal or greater severity;
  • Sensory polyneuropathy post chemotherapy or in the context of cancer or AIDS;
  • Patients with complex regional pain syndrome;
  • Trigeminal neuralgia;
  • Patients with clinically significant or uncontrolled hepatic, metabolic, gastrointestinal, cardiovascular, respiratory, neurological (other than neuropathy), psychiatric, hematological, renal, or dermatological disease, or any other medical condition that might interfere with the evaluation of study medication according to Investigator's medical judgment;
  • Patients on statins metabolized by CYP3A4, (e.g. simvastatin, atorvastatin) and abnormal CPK level;
  • Major depression;
  • Serum creatinine >150 μmol/L;
  • ALT 3 x ULN;
  • Total bilirubin > 1.5 x ULN except known Gilbert syndrome;
  • Presence of signs of clinically significant abnormalities on a standard electrocardiogram (ECG) recording at the screening visit according to Investigator's medical judgment;
  • Pregnant or breastfeeding women;
  • Women of childbearing potential (WOCBP), not protected by highly effective contraceptive method of birth control;
  • Patients with diabetes mellitus and time between diagnosis of diabetes and enrolment <6 months;
  • Patients with diabetes mellitus and HbA1c >10% or fasting plasma glucose >250 mg/dL;
  • Use of the following drugs within 7 days prior to start with the pain intensity assessment (Visit 2):
  • Antidepressants (except for stable [>30 days] regimens of Selective serotonin reuptake inhibitors (SSRIs) for treatment of anxiety or depression), anticonvulsants or mexiletine for the treatment of pain;
  • Opioids or morphinomimetics;
  • Fatty acid supplements, primrose oil, myoinositol, chromium picolinate that are known to be used in neuropathic pain;
  • Acetyl salicylic acid (ASA) except up to 325 mg/d for myocardial infarction or transient ischemic attack prophylaxis;
  • Benzodiazepines other than indicated at low doses for sleep disorders;
  • Capsaicin patch;
  • Lidocaine patch;
  • Electroconvulsive therapy within 30 days of baseline evaluation;
  • CYP3A4 potent and moderate inhibitors;
  • CYP3A4 potent and moderate inducers;
  • Substrates of CYP3A4 with narrow therapeutic window.
