Study summary

This is a prospective, randomized, double blind, comparative, experimental controlled Phase 3 clinical trial to assess the efficacy, safety and superiority of F0343 (gabapentin combined with B vitamins) compared to gabapentin alone for treating neuropathic pain in subjects with chronic distal diabetic polyneuropathy.

Read the detailed description

Subjects will be assigned to one of the two arms of the study, after having been deemed eligible during the screening visit in random double-blind design. Subjects will be evaluated for a 4 week period.

OBJECTIVES

  • To assess the effects of F0434 and gabapentin alone on neuropathic pain and Quality Of Life (QOL) of subjects with diabetic neuropathy through a current and validated neuropathic pain scale along with the QOL questionnaire.

Interventions

  • DrugF0434

    F0434 will be administered orally with an initial dosage of 3 capsules per day divided into 3 doses with a time interval of 8 hours between each dose. The subject will continue with this dosage for one week and afterwards, the initial dosage will be increased from 3 capsules per day divided into 3 doses with the same time interval between doses, until visit 3 (week 2).

What researchers measure

Primary outcomes

  1. Mean Neuropathic Pain Score at Visit 3 (Week 1)

    Neuropathic pain score included 10 pain descriptors (intensity, stinging, burning, dull pain, coldness, sensitivity, numbness, depth, superficial and unpleasant) quantified on a 0 (no symptoms) to 10 (worst symptoms imaginable). Questionnaire generated a score in each of the relevant dimensions and a total score of 0-100. Higher score indicated a greater intensity of pain.

    Time frame: Visit 3 (Week 1)

  2. Mean Neuropathic Pain Score at Visit 4 (Week 2)

    Neuropathic pain score included 10 pain descriptors (intensity, stinging, burning, dull pain, coldness, sensitivity, numbness, depth, superficial and unpleasant) quantified on a 0 (no symptoms) to 10 (worst symptoms imaginable). Questionnaire generated a score in each of the relevant dimensions and a total score of 0-100. Higher score indicated a greater intensity of pain.

    Time frame: Visit 4 (Week 2)

  3. Mean Neuropathic Pain Score at Visit 5 (Week 3)

    Neuropathic pain score included 10 pain descriptors (intensity, stinging, burning, dull pain, coldness, sensitivity, numbness, depth, superficial and unpleasant) quantified on a 0 (no symptoms) to 10 (worst symptoms imaginable). Questionnaire generated a score in each of the relevant dimensions and a total score of 0-100. Higher score indicated a greater intensity of pain.

    Time frame: Visit 5 (Week 3)

  4. Mean Neuropathic Pain Score at Visit 6 (Week 4)

    Neuropathic pain score included 10 pain descriptors (intensity, stinging, burning, dull pain, coldness, sensitivity, numbness, depth, superficial and unpleasant) quantified on a 0 (no symptoms) to 10 (worst symptoms imaginable). Questionnaire generated a score in each of the relevant dimensions and a total score of 0-100. Higher score indicated a greater intensity of pain.

    Time frame: Visit 6 (Week 4)

Secondary outcomes

  1. Quality of Life Survey Assessed Using Short Form 36 (SF-36) Questionnaire

    SF-36 is a standardized health survey consisting of 36 questions to measure functional health status. Summary scores are calculated using the following 8 dimensions: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. The score for a component is obtained by SF-36 algorithm and it is represented as an average of the individual question scores, which are scaled 0 (not functioning) to 100 (highest functioning). Higher scores are indicative of a better health status.

    Time frame: Visit 2 (Baseline) to Visit 6 (Week 4)
