A Multicenter, Open-label Clinical Trial to Evaluate the Efficacy and Safety of Once Daily Mirvaso® Gel in Patients With Chronic Persistent Vascular Facial Erythema.

Study Overview
=================
Brief Summary
-----------------
This study evaluates the efficacy of Mirvaso® in the treatment of chronic persistent vascular facial erythema, after 4 weeks of treatment, by the Clinician erythema assessment.

Detailed Description
-----------------
This is a multicenter, open-label trial in research participants with chronic persistent vascular facial erythema. All eligible research participants will receive Mirvaso® gel once daily for 4 weeks, and then will be followed-up for another 2 weeks. The study will include 4 clinical visits: before Day 1, on Day 1, Day 29 and Week 6. Within 5 days before Day 1, the research participant will have a screening visit for confirmation of eligibility. On Day 1 and on Day 29, the research participant will have Mirvaso® gel applied, at the research site, and the evaluation will be conducted before application and 3 hours after application; During Days 2-28, research participants will have Mirvaso® gel applied once daily, at home; On Week 6, the research participants will go back to the research site for evaluation. No Mirvaso® gel will be applied after the visit on Day 29; Unscheduled visits may be performed during the trial for any safety reason.

Female patients without childbearing potential (e.g., before menstruating, post-menopausal [absence of menstrual bleeding for 1 year prior to study entry], hysterectomy, or bilateral oophorectomy, less than one year after menopause). Patients willing and able to fulfill the protocol requirements and duration. Patients who understand and sign the Informed Consent Form at study inclusion, before any study procedure is carried out. Exclusion Criteria: - Any research participant that meets one or more of the following criteria is not eligible for the trial: Female patients who are pregnant, breastfeeding or planning for pregnancy. Current treatment with monoamine oxidase inhibitors, barbiturates, opiates, sedatives, systemic anesthetics or alpha agonists. Patients who started or changed their doses of tricyclic antidepressants, cardiac glycosides, beta-blockers or other anti-hypertensive agents, in the 3 months prior to study entry. Current diagnosis of Raynaud syndrome, thromboangiitis obliterans, orthostatic hypotension, severe cardiovascular disease, coronary or cerebral insufficiency, hepatic or renal failure, sclerodermia, Sjögren syndrome, or depression. Any chronic or severe uncontrolled disease or medical chronic which may interfere with the interpretation of the study results, or may present a significant healthcare risk to the patient, if he/she participates in the study in accordance with the investigator judgment. (e.g. endocrine tumors, chromocytomas, systemic diseases that cause vascular erythema). Known or suspected allergies or hypersensitivities to any of the components of the study treatments, including the active substance of brimonidine tartrate (see summary of product characteristics). Patients who received, applied or ingested the following treatments in accordance with the time period specified before Day 1: Topic facial treatments or procedures: Any dermatological/surgical facial procedure - 4 weeks. Immunomodulators (e.g. Methotrexate, Cyclosporin) - 4 weeks. Mirvaso® - 4 weeks. Systemic treatments: Isotretinoin - 6 months. Immunomodulators - 90 days. Phototherapy - 4 weeks. Exposure to excessive ultraviolet radiation within a week before Day 1 visit. Presence of beard or excessive facial hair at Day 1, which interferes with the study treatment or study assessments and refusal to remove it during the study period. Patients who do not wish to abstain from the use of forbidden medication or excessive exposure to ultraviolet radiation during the study period. Vulnerable research participants (as deprived of freedom), in accordance with Section 1.61 of the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use - ICH for Good Clinical Practices. Current participation in any other clinical study with a drug or device OR participation within 30 days prior to Day 1 OR in an exclusion period of a previous clinical study (when possible).
