Brimonidine Tartrate for the Treatment of Injection Related Erythema

Phase 4
Withdrawn
Conditions
Relapsing-Remitting Multiple Sclerosis (RRMS)
Interventions
Registration Number
NCT02568111
Lead Sponsor
Biogen
Brief Summary

The primary objective of this study is to evaluate the Injection Related Erythema (IRE) mitigation effect of a single administration of brimonidine tartrate in comparison with a vehicle gel (placebo).

The secondary study objectives are to evaluate the IRE mitigation effect of a single administration of brimonidine tartrate in comparison with a vehicle gel on a more stringent definition scale, in accordance with the primary endpoint of the original brimonidine pivotal trials and participants' satisfaction with the overall appearance of their skin.

Detailed Description

Participants naïve to treatment with subcutaneous (SC) interferons or oral Disease Modifying Therapy (DMT) who are about to start PLEGRIDY PEN therapy will be screened for participation in this Phase IV trial. Participants will remain on Plegridy therapy as prescribed by their physician. Plegridy will not be provided to participants by Biogen as a part of this study.

Primary Outcome Measures
NameTimeMethod
Change in either Clinician's Erythema Assessment (CEA) or Patient Erythema Self-Assessment (PSA) scale measured as at least 1-grade improvement on CEA and/or at least 1-grade improvement on PSA scale assessed by the physician and participantBefore and after 6 hours of gel application

Investigator will evaluate participant's erythema (redness) at the site of injection on a scale of 0 (clear) to 4 (severe) with higher scores indicating higher levels of erythema. Participants rate erythema at the site of injection on a scale of 0 (clear) to 4 (severe) with higher scores indicating higher levels of erythema.

Secondary Outcome Measures
NameTimeMethod
Composite change in both CEA and PSA scale measured as at least 1-grade improvement on CEA and 1-grade improvement on PSA respectivelyBefore and after 6 hours of gel application

This composite endpoint is considered to be sensitive enough and directly correlated with participants' satisfaction therapy outcomes.

Composite change in both CEA and PSA scale measured as at least 2-grade improvement on CEA and 2-grade improvement on PSABefore and after 6 hours of gel application
Participant's self-assessment of satisfaction with the overall appearance of their skin by using a Patient's Assessment of Appearance (PAA) grading scaleBefore and after 6 hours of gel application

PAA satisfaction score will describe how satisfied the participants are with the overall appearance of skin on a scale of 0 (very satisfied) to 4 (very dissatisfied).
