Study Description

Brief Summary:

Our goal is to determine whether daily oral administration of VPD-737 (5 mg) is effective and safe in adolescents and adults with Epidermolysis Bullosa (EB).

Condition or disease	Intervention/treatment	Phase
Epidermolysis Bullosa Pruritus	Drug: VPD-737 Other: Placebo	Phase 2

Detailed Description:

Itch is the most common complaint reported by patients with EB of all subtypes, and there is no current effective treatment. Itch often triggers scratching that creates new wounds and increases EB disease severity. This study aims to target the physiological mechanisms of pruritus (itch) in patients with EB .

Substance P is a major mediator of pruritus and binds to the receptor neurokinin-1 (NK1), which is expressed in the central nervous system and the skin.

VPD-737 (serlopitant), a novel drug that inhibits the NK1 receptor, has been shown to reduce severe itch in a previous study of 257 adult patients with chronic pruritus.

The investigators are now testing VPD-737 in 14 patients with EB in a Phase II randomized, placebo-controlled, double-blinded clinical trial.

Arms and Interventions

Arm	Intervention/treatment
Experimental: 5 mg VPD-737 5 mg tablets of VPD-737 to be taken daily by mouth for 56 days	Drug: VPD-737 VPD-737 inhibits the receptor neurokinin-1. Other Name: Serlopitant
Placebo Comparator: Placebo Placebo tablets to be taken daily by mouth for 56 days	Other: Placebo Matching tablets to VPD-737 tablets without active drug

Outcome Measures

Primary Outcome Measures :

Change in EB associated itch [ Time Frame: NRS recorded by subject daily, from screening visit through the end of the study ]
Determine the efficacy of Serlopitant compared with placebo on reducing EB itch as measured by patient self-reports using a numeric rating scale (NRS) for itch severity and the Stanford EB itch questionnaire. NRS is included in the Stanford EB Itch survey.

Secondary Outcome Measures :

Wound healing determination [ Time Frame: screening, month 1, month 2 ]
Wound dimensions, including length, width, and area (in cm2), will be obtained using the Canfield system. Changes in dimensions between visits as well as changes in dimensions from baseline will be recorded.
