Fycompa in Subjects With Small Fiber Neuropathy (SFN)

January 26, 2016 updated by: Todd Levine, MD, PNA Center for Neurological Research

Randomized Crossover Trial of Fycompa in the Treatment of Pain Associated With Small Fiber Neuropathy (SFN)

This is a Phase II, 2 arm randomized crossover study. Subjects will be assigned to either active agent or placebo and then crossover to the other arm. This study is designed to evaluate whether Fycompa improves the quality of life in patients with small fiber neuropathy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will enroll 30 patients from our center alone with a proven SFN diagnosis by a skin biopsy assessment of intraepidermal nerve fiber density. The patients must also have a pain score of a least 5 on a VAS Scale. Patients will receive Fycompa 2mg tablets. Each week patients will be allowed to titrate up by 2mgs up to a maximum dose of 8mg a day. This dosing has been used in numerous pain studies when no single dose has been proven to be effective. This does not seem to reduce the validity of the placebo phase. Patients can choose the dose they feel is best tolerated and most efficacious. Once patients choose this dose they will be randomized into two arms. Each arm will last 6 weeks. Such that patient will receive the dose they chose as most efficacious for 6 weeks or matching placebo for 6 weeks. Then each patient will crossover to the other arm. Investigator will assess compliance by counting pills at each visit. This will provide the ability to see which dose most patients prefer and then study the dose in a blinded randomized fashion. There will be 5 office visits and 3 phone visits in the study and . Patients will keep a diary of weekly VAS pain scores.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To Assess the Change of Pain Symptoms Upon Treatment of Fycompa in Comparison to Placebo using Visual Analog Scale (VAS) andBrief Pain inventory(BPI) Short Form
Time Frame: Baseline, Week 5, Week 12 and Week 18
Baseline, Week 5, Week 12 and Week 18

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
