Eligibility criteria:
Inclusion Criteria:

          1. Healthy male or non-pregnant female aged ≥ 18 years with a clinical diagnosis of
             facial papulopustular rosacea.

          2. Subjects must have provided IRB approved written informed consent.

          3. Subjects must have at least 15 and not more than 50 inflammatory facial lesions (i.e.,
             papules/pustules) at screening and baseline visits. For the purposes of study
             treatment and evaluation, these lesions should be limited to the facial treatment area

             excluded from the count.

          4. Subjects must have no more than 2 nodulocystic lesions on the face at Screening and
             Baseline visits.

          5. Subjects must have a definite clinical diagnosis of facial papulopustular rosacea
             severity grade 3 or 4 as per the Investigator Global Assessment (IGA) (per Table 1
             below) at screening and baseline visits.

          6. Subjects must have persistent erythema on the face with moderate (2) score or higher
             (per table 2 below) at screening and baseline visits.

          7. Subjects must have a mild (1) to moderate (2) score for telangiectasia on the face.
             (per table 3 below) at screening and baseline visits.

             flare-ups (e.g., spicy foods, thermally hot foods and drinks, hot environments,
             prolonged sun exposure, strong winds and alcoholic beverages)

          9. Subjects must be willing to refrain from using all other topical medications for
             rosacea during the 12-week treatment period, other than the investigational product.

         10. Female Subjects of childbearing potential (excluding women who are or premenarchal,
             surgically sterilized (by hysterectomy) or postmenopausal for at least 1 year prior to
             screening), in addition to having a negative urine pregnancy test, must be willing to
             use an acceptable form of birth control during the study from the day of the first
             dose administration to 30 days after the last administration of study drug. For the
             purpose of this study the following are considered acceptable methods of birth
             control: oral or injectable contraceptives, contraceptive patches, Depo-Provera®
             (stabilized for at least 3 months prior to screening), NuvaRing® (vaginal

             stabilized on the same type for at least three months prior to screening and must not
             change the method during the study. A sterile sexual partner is NOT considered an
             adequate form of birth control.

         11. All male Subjects must agree to use accepted methods of birth control with their
             partners, from the day of the first dose administration to 30 days after the last
             administration of study drug. Abstinence is an acceptable method of birth control.

         14. Subjects must be in good health and free from any clinically significant disease,
             including but not limited to, conditions that may interfere with the evaluation of
             facial rosacea. Such conditions include but are not limited to the following:
             autoimmune disease; acne vulgaris on the face; seborrheic dermatitis on the face;

Patient description (patient's own words): I'm 41, married with 2 lovely kids who are 5 and 9 years old. I have an IUD and I don't want to have more kids. I don't smoke or drink alcohol. I had to go to the dermatology clinic because I had terrible redness on my face, especially on my forehead and cheeks. It got worse in the summer and after being under the sun. I'm usually healthy. They conducted a physical exam and they found several lesions and pustules on my forehead, cheeks and nose and they also found some signs of erythema and telangiectasia. My vitals were normal, and my BMI is 21.

Does the patient match the trial criteria? Entailment
