• •4. Patients with a skin condition such as Kaposi's varicelliform eruption, scabies, molluscum contagiosum, impetigo, psoriasis, severe acne, connective tissue disorder, or Netherton's syndrome, or any other disease that could impact study evaluations.
• •5. Use of any prohibited medication.
• •Prohibited concomitant medications, therapy, etc. during the defined period are as listed in the bullets below. If a patient requires any of these medications throughout the study period, he/she may be excluded from or discontinued from the study, at the discretion of the Investigator and medical monitor.
• •\- From 6 months prior to the first application of study drugs to the completion of the
• •Follow-up visit or discontinuation:
• •* Biological products that might have significantly affected the evaluation of atopic dermatitis condition (e.g., tumor necrosis factor \[TNF\] inhibitors, anti- immunoglobulin \[Ig\]E antibodies, anti-CD20 antibodies, anti-interleukin \[IL\]-4 receptor).
• •* From 28 days prior to the first application of study drug until the completion of the Follow- up visit or discontinuation:
• •* Corticosteroid preparations (oral, injection, and suppository preparations) and topical corticosteroids that were classified as super-high potency (clobetasol propionate). Eye drop and nasal preparations are allowed. Inhaled preparations are allowed if used for a stable condition and at a stable dose for \> 28 days before Screening, and are continued at the same dose throughout the study.
• •* Oral preparations and injections of immunosuppressants (cyclosporine, methotrexate, azathioprine, tacrolimus, etc.);
• •* Excessive sun exposure, tanning booth, other ultraviolet (UV) light source and phototherapy including psoralen and ultraviolet A (PUVA) therapy.
• •* From 14 days prior to the first application of the study drug to the completion of the
• •Follow-up visit or discontinuation:
• •* Herbal medicines for atopic dermatitis (topical and oral preparations), unless specifically approved by the sponsor;
• •* Eucrisa™ (crisaborole) and any other topical phosphodiesterase 4 (PDE4) inhibitor;
• •* Tacrolimus and pimecrolimus cream and/or ointment;
• •* Topical corticosteroids that were classified as low, medium, or high potency (fluocinonide, triamcinolone acetonide, desonide, hydrocortisone). Eye drops and nasal preparations are allowed.
• •* From 7 days prior to the first application of the study drug to the completion of the
• •Follow-up visit or discontinuation:
• •* Oral or intravenous antibiotics, antifungal or antivirus medications
• •* Antihistamines/anti-allergics (oral, topical and injections): diphenhydramine, chlorpheniramine maleate, hydroxyzine).
• •NOTE: The following antihistamines are allowed:
• •* Loratadine, fexofenadine hydrochloride, cetirizine hydrochloride
• •6. Pregnant or lactating females.
• •7. History of sensitivity to the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the Investigator or medical monitor, contraindicates their participation.
• •8. The patient has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives, or twice the duration of the biological effect of the investigational product (whichever is longer).
• •9. Current or a history of cancer within 5 years.
• •10. Patients with active infection in atopic dermatitis areas requiring antibiotics, antifungals, or antiviral agents within 7 days of Baseline (Day 0).
• •11. Patients with pruritus due to conditions other than atopic dermatitis that, in the opinion of the Investigator, would either interfere with study evaluations or affect the safety of the patient.
• •12. Patients with advanced disease or recent abnormal laboratory test values that could affect the safety of the patient or the implementation of this study, as determined by medical records.
• •13. History of and/or concurrent condition of serious hypersensitivity (anaphylactic shock or anaphylactoid reaction) to PDE4 inhibitors.
• •14. Prior exposure to RVT-501.
• •15. Evidence of significant hepatic, renal, respiratory, endocrine, hematologic, neurologic, psychiatric, or cardiovascular system abnormalities or laboratory abnormalities that will affect the health of the patient or interfere with interpretation of the results.
• •16. The patient has excessive sun exposure, is planning a trip to a sunny climate that would involve excessive sun exposure, or used tanning booths within 28 days prior to Baseline (Day 0) or is not willing to minimize natural and artificial sunlight exposure during the study.
• •Other Eligibility Criteria Considerations:
• •To assess any potential impact on patient eligibility with regard to safety, the Investigator must refer to the following document for detailed information regarding warnings, precaustions, contraindications, adverse events, and other significant data pertaining to the investigational product being used in the study:
