Brief summary

The purpose of this study is to measure the effects of azelaic acid on Demodex folliculorum counts and disease condition via a split face design in approximately twenty patients with mild to moderate rosacea. The investigators hypothesize that treatment of rosacea with azelaic acid will lead to a decreased Demodex folliculorum count as well as an improvement in lesion count and redness.

Detailed description

This is a split face, randomized, single blind, single center study. Male and female (non-pregnant, non-nursing) subjects, age 18 or greater, with mild to moderate papulopustular facial rosacea, with bilateral facial involvement, and no more than two nodules will be enrolled. Subjects will be randomized 1:1 by the study coordinator using a standard randomization table to receive azelaic acid twice daily on either the left side or the right side of the face and no treatment on the other side of the face. Subjects must have a positive Demodex folliculorum standardized skin surface biopsy, defined at \>5 mites cm at Screening/Baseline on at least one of two different SSSB specimens on bilateral sides of the face. The SSSB test location will ideally be on the cheek, but may be done in the most disease involved area. Subjects will be seen at Screening/Baseline, Week 1 and Week 4. Standard topical washout periods will be observed. At each visit, rosacea will be evaluated by lesion count, IGA and two Demodex SSSB tests done on each side of the face. Safety will be monitored at each visit using the Investigator Skin Irritation Assessment.

Intervention model description

This is a split face, randomized, single blind, single center study. Male and female (non-pregnant, non-nursing) subjects, age 18 or greater, with mild to moderate papulopustular (based on Investigator Global Assessment) facial rosacea, with bilateral facial involvement, and no more than two nodules will be enrolled. Subjects will be randomized 1:1 by the study coordinator using a standard randomization table to receive azelaic acid (Finacea® Gel, 15%) twice daily on either the left side or the right side of the face and no treatment on the other side of the face.

Inclusion criteria

* Male and female subjects, ages 18 and over, with mild to moderate paulopustular rosacea with bilateral facila involvement, who agrees to participate and provide written consent. * Positive Demodex folliculorum SSSB, defined as \>5 mites/cm on at least on of two different SSSB specimens on bilateral sides of teh face. * Have an IGA of mild to moderate rosacea, rating between 2 and 5.

Exclusion criteria

* Use of topical therapy for rosacea or other skin conditions on the face within two weeks of Baseline. * Use of oral medications for the treatment of rosacea that have been started or altered within the past three months. * Presence of a concurrent medical condition or skin condition, which is determined by the investigator to potentially interfere with study outcomes or patient assessments. * Subjects with known allergy or sensitivity to azelaic acid gel or components therein, such as propylene glycol. * Subjects with known allergy or sensitivity to cyanoacrylates or formaldehyde. * Presence of more than two nodules. * Female subjects who are not postmenopausal for at least 1 year, surgically sterile or willing to practice effective contraception during the study. Reliable methods of birth control are: abstinence, oral contraceptives, intrauterine device, DepoProvera, tubal ligation or vasectomy of the partner in a monogamous relationship. An acceptable, though less reliable, method involves the careful use of condoms and spermicidal foam or gel and/or a cervical cap or sponge. Nursing mothers, pregnant women and women planning to become pregnant while on study are to be excluded.
