Official title: Neuropathic Pain Treatment Using F0434 vs. Gabapentin in Patients With Chronic Distal Diabetic Polyneuropathy: A Randomized, Controlled, Double-blind Study

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.
Being tested
F0434, Gabapentin

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • F0434Drug

    Also called Gabapentin with thiamine and cobalamin

    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).

  • GabapentinDrug

    Also called Gababion, Gavindo

    Gabapentin 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 is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 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.

    Measured: 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.

    Measured: 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.

    Measured: Visit 6 (Week 4)

Secondary outcomes (1)
  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.

    Measured: Visit 2 (Baseline) to Visit 6 (Week 4)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing F0434 and Gabapentin in people with Diabetic Neuropathies and Polyneuropathies, run by Merck KGaA, Darmstadt, Germany at 1 site in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Oct 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Neuropathic Pain Score at Visit 3 (Week 1) (time frame: Visit 3 (Week 1)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2014.
