Eligibility Criteria

• 1. Signed ICF indicating that the patient understands the purpose of, and procedures required for the study and is willing to participate in the study.
• 2. Males and non-pregnant, non-lactating females aged ≥18 at the time of signing the informed consent.
• 3. Patients with clinical diagnosis of chronic plaque psoriasis and stable disease for at least 6 months prior to the study.
• 4. Body surface area (BSA) involvement ≥ 3% and ≤ 20% (the patient's face, scalp, groins, palms and soles should be excluded from the percent of total BSA (%BSA) calculations).
• 5. A Physician's Global Assessment (PGA) score of 2 (mild), 3 (moderate) or 4 (severe) at screening and baseline.
• 6. Female patients of childbearing potential (\*WOCBP) must not be pregnant or lactating at the time of screening/baseline visit as documented by a negative urine pregnancy test with a sensitivity to at least 25 mIU/ml hCG:
• 7. Female patients of childbearing potential 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.
• 1. For the purposes of this study the following are considered acceptable methods of birth control: oral or injectable contraceptives, contraceptive patches, medroxyprogesterone acetate (ex. Depo-Provera®) with stabilized use for at least 3 months, vaginal contraceptive (ex. etonogestrel/ethinyl estradiol vaginal ring (ex. NuvaRing®), contraceptive implant with etonogestrel or equivalent, double barrier methods, (e.g. condom and spermicide), intrauterine device (IUD), true abstinence (if in line with patient's lifestyle).
• 2. Patients on hormonal contraception must be stabilized on the same type for at least three months prior to enrollment in the study and must not change the method during the study. A sterile sexual partner is not considered an adequate form of birth control.
• 3. If a patient who was abstinent becomes sexually active during the study, a second acceptable method of birth control should be used and documented.
• 8. Willing and able to adhere to the lifestyle restrictions specified in this protocol.
• 9. Patients must be in good health and free from any clinically significant disease, which may interfere with the evaluation of plaque psoriasis or the administration of the investigative product.
• 10. Patients must be willing to refrain from using all other topical plaque psoriasis products during the 12-week treatment period, other than the investigational product.
• 1. Known allergies, hypersensitivity, or intolerance to any of the ingredients of study treatment interventions, or components/ excipients thereof (refer to the prescribing information of VTAMA®), or drug or other allergy that, in the opinion of the investigator, contraindicates participation in the study.
• 2. Current diagnosis of unstable forms of psoriasis (other than plaque variant) in the treatment area, including guttate, erythrodermic, exfoliative or pustular psoriasis.
• 3. Patients with other inflammatory skin disease in the treatment area that may confound the evaluation of the plaque psoriasis (e.g., atopic dermatitis, contact dermatitis, tinea corporis, and or any others in the opinion of the Investigator).
• 4. Presence of pigmentation, extensive scarring, or pigmented lesions in the treatment areas, which could interfere with the rating of efficacy parameters.
• 5. Patients with current immunosuppression.
• 6. Ultraviolet (UV) light therapy or prolonged exposure to natural or artificial sources of UV radiation (eg, phototherapy, tanning booths, or therapeutic sunbathing), laser therapy, tattoos removal, skin wraps or exfoliant techniques or Fraxel within 4 weeks prior to the baseline visit and/or plans to have such exposures during the study which could potentially impact the patient's psoriasis (as determined by the Investigator).
• 7. Use of biological treatments for psoriasis within the last 6 months of the baseline evaluation.
• 8. Patients that have been treated with systemic steroids, systemic antibiotics, systemic anti-psoriatic treatment (i.e., methotrexate, cyclosporine, hydroxyurea), PUVA therapy, ultraviolet- B Therapy or systemic anti-inflammatory agents within 1 month or within 5 half-lives (whichever is longer) before Baseline.
• 9. Use of any of the following therapies within two weeks prior to baseline:
• * topical anti-psoriatic drugs (e.g., salicylic acid, anthralin, coal tar, calcipotriene, tazarotene)
• * topical corticosteroids
• * immunosuppressive drugs (e.g., tacrolimus, pimecrolimus)
• * topical retinoids
• 10. Received an investigational intervention within 30 days or 5 half-lives prior to the first dose of study intervention, whichever is longer.
• 11. Documented medical history of uncontrolled, clinically significant intercurrent medical condition(s) (i.e., chronic infectious disease, system disorder, organ disorder, cardiovascular, gastrointestinal, hematological, hepatic, neurological, pancreatic, renal disease, severe psychiatric condition, etc.) for which, in the opinion of the investigator, participation would not be in the best interest of the patient (e.g., compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
• 12. Employees of the Investigator or research center or their immediate family members.
• 13. Females who are pregnant, breast feeding, or who wish to become pregnant during the study period.
• 14. Patients who have received chemotherapy or radiation therapy and/or anti-neoplastic agents within 3 months prior to screening/baseline.
• 15. Patients who are unable or unwilling to give informed consent.
• 16. Patients, who in the opinion of the Investigator, would be non-compliant with the requirements of the study protocol.
• 17. Patients who consume excessive amounts of alcohol (greater than two drinks per day) or use drugs of abuse (including, but not limited to, cannabinoids, cocaine and barbiturates) within one year prior to screening.
