Male participants with a partner of childbearing potential must also agree to use any two of the highly effective contraception methods listed below between them and their partner. This criterion must be followed from screening visit to 6 weeks after the last dose in females and for 90 days after the last dose for males; The following applies to all female participants with childbearing potential and female partners of male participants enrolled in the study; Implantable progestogen-only hormone contraception associated with inhibition of ovulation; Intrauterine device; Intrauterine hormone-releasing system; Bilateral tubal occlusion; Combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation:; Oral; Intravaginal; Transdermal; Injectable; Progestogen-only hormone contraception (oral or injectable) associated with inhibition of ovulation; Vasectomized partner; Sexual abstinence -this is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study intervention. The reliability of sexual abstinence needs to be evaluated about the duration of the study and the preferred and usual lifestyle of the participant; A combination of male condoms with either cervical cap, diaphragm, or sponge with spermicide (double-barrier methods); The following applies to all male participants in the study:; Sexual abstinence- this is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study intervention. The reliability of sexual abstinence must be evaluated for the study and the participant's preferred and usual lifestyle; A combination of male condoms with either cervical cap, diaphragm, or sponge with spermicide (double-barrier methods); Vasectomy

• Documented history of clinically significant adverse reactions with the use of TCS, such as skin atrophy, allergic reactions, or systemic effects that, in the opinion of the investigator, outweigh the benefits of retreatment; For Plaque Psoriasis Cohort:
• Confirmed diagnosis of plaque psoriasis for at least 6 months prior to baseline (Day 0)
• Plaque psoriasis involving ≥10% body surface area (BSA) in the affected skin other than the face and scalp at screening and baseline (Day 0)
• Static Physician's Global Assessment (sPGA) score ≥3 at screening and baseline (Day 0)
• PASI score of ≥12 at screening and baseline (Day 0)
• Subject must be candidate for phototherapy or systemic therapy
• Subject had no significant flare in psoriasis for at least 3 months before screening
