Trial Outcomes & Findings for Effects of Aminocaproic Acid (ACA) on Rosacea-specific Inflammation (NCT NCT01398280)

NCT ID: NCT01398280

Last Updated: 2019-09-13

Results Overview

Serine protease activity of KLK5 in adult skin from patients with rosacea is measured after treatment with vehicle or aminocaproic acid cream. Protease activity of facial skin surface is monitored using a synthetic fluorogenic trypsin-like proteinase substrate. Protease activity is monitored as an increase of fluorescence (RFU/uL) with SpectraMax GEMINI EM.

Measure
Vehicle Cream
Subjects will apply vehicle twice daily for up to 12 weeks with 5-6 visits and 2 telephone visits. Investigator and subject will be blinded. Tape strip samples will be collected from facial skin at each visit to assess KLK activity and LL-37 expression. Vehicle cream: Vehicle cream moisturizer twice daily for up to 12 weeks
Aminocaproic Acid (ACA)
Subjects will treat their facial skin twice daily for up to 12 weeks with 5-6 visits and 2 telephone visits. Investigator and subject will be blinded. Tape strip samples will be collected from facial skin at each visit to assess KLK activity and LL-37 expression. Topical aminocaproic acid (ACA) mixed with Vanicream: 25% Aminocaproic acid cream twice daily for up to 12 weeks.
