• Have a diagnosis of moderate to severe plaque psoriasis of the scalp at screening and baseline

• Must be a candidate for phototherapy and/or systemic therapy for either body or scalp psoriasis lesions.

• Have moderate to severe plaque psoriasis at screening and baseline

• Must be in good health (except for psoriasis) as judged by the Investigator, based on medical history, physical examination, 12-lead electrocardiogram (ECG), clinical laboratories, and urinalysis

• Must meet laboratory criteria

• Females of childbearing potential (FCBP)* must have a negative pregnancy test at screening and baseline. While on investigational product (IP) and for at least 28 days after taking the last dose of investigational product, FCBP who engage in activity in which conception is possible - must use one of the approved contraceptive** options described below:

Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner's vasectomy; OR Option 2: Male or female condom (latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]; PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.

*A female of childbearing potential is a sexually mature female who 1) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for at least 24 consecutive months (that is, has had menses at any time during the preceding 24 consecutive months).

** The female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal contraception should be initiated at least 28 days before randomization).

Exclusion Criteria:

• Other than psoriasis, history of any clinically significant uncontrolled disease.

Any condition, including the presence of laboratory abnormalities, which would place the subject at unacceptable risk if he/she were to participate in the study.
