This is an interventional treatment trial for Alopecia Areata focused on measuring Alopecia areata Read More

Inclusion Criteria:

Males or females, 18 years or older at the time of signing the informed consent document.

Understand and voluntarily sign an informed consent document prior to any study-related assessments/procedures are conducted.

Able to adhere to the study visit schedule and other protocol requirements. Subject with a diagnosis of patchy scalp alopecia areata present for at least 6 months, and up to a maximum of 10 years.

Patients with ≥50% and <95% total scalp hair loss at Baseline as measured using the SALT score to qualify as moderate to severe AA; and 95%-100% scalp hair loss to qualify as AA totalis/universalis.

Must meet the following laboratory criteria White blood cell count ≥ 3000/mm3 (≥ 3.0 x 109/L) and < 14,000/mm3 (< 14 x 109/L). Platelet count ≥ 100,000/μL (≥ 100 x 109/L). Serum creatinine ≤ 1.5 mg/dL (≤ 132.6 μmol/L). AST (SGOT) and ALT (SGPT) ≤ 2 x upper limit of normal (ULN). If the initial test shows ALT or AST > 2 times the ULN, one repeat test is allowed during the Screening Phase.

Total bilirubin ≤ 2 mg/dL (34 μmol/L). If the initial test shows total bilirubin > 2 mg/dL (34 μmol/L), one repeat test is allowed during the Screening Phase.

Hemoglobin ≥ 10 g/dL (≥ 6.2 mmol/L).

Females of childbearing potential (FCBP) must have a negative pregnancy test at Screening and Baseline. While on investigational product and for at least 28 days after taking the last dose of investigational product (IP), 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 spermicide PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.

Male subjects (including those who have had a vasectomy) who engage in activity in which conception is possible must use barrier contraception (male latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]) while on IP and for at least 28 days after the last dose of IP.

No evidence of hair regrowth present at Baseline.

EXCLUSION CRITERIA:

The presence of any of the following will exclude a subject from enrollment:

Hepatitis B surface antigen positive at Screening (Visit 1). Hepatitis C antibody positive at Screening (Visit 1). History of positive human immunodeficiency virus (HIV), or congenital or acquired immunodeficiency (eg, Common Variable Immunodeficiency [CVID]). Subjects deemed at risk by the study investigator, may also undergo testing for human immunodeficiency virus (HIV). Subjects deemed at risk include those with a history of injection drug use, homosexual subjects, and subjects with known sexual contact with an HIV positive partner.

Active TB or a history of inadequately treated TB. Active substance abuse or a history of substance abuse within six months prior to Screening.

Pregnant or breast feeding. History of allergy to any component of the IP.

Major surgery within eight weeks prior to Screening (Visit 1) and/or planned surgery during the length of the study.

Malignancy or history of malignancy, except for:

treated (ie, cured) basal cell or squamous cell in situ skin carcinomas; treated (ie, cured) cervical intraepithelial neoplasia (CIN) or carcinoma in situ of the cervix with no evidence of recurrence within 5 years prior to Screening (Visit 1).

Unstable asthma (eg, acute episodes of exacerbation [nocturnal episodes, sudden episodes triggered by unidentifiable factors] despite a stable regimen of anti-asthmatic medications); prior episode(s) of life-threatening asthma; or asthma that requires inhaled budesonide or equivalent at >1200 μg/day or fluticasone propionate at > 880 μg/day along with another anti-asthmatic drug such as a long-acting beta-agonist.

A history of and/or concurrent condition of serious hypersensitivity (eg, anaphylaxis) to drugs, foods, or other allergens without access to emergency rescue medication such as epinephrine.

Persistent or recurring bacterial infection requiring systemic antibiotics, or clinically significant viral or fungal infections, within two weeks of Screening (Visit 1). Any treatment for such infections must have been completed at least two weeks prior to the Screening Visit and no new/recurrent infections should have occurred prior to the Baseline Visit.

Active skin infection requiring systemic antimicrobials at Baseline/Randomization (Visit 2).

Skin lesion(s) due to conditions other than AA that would interfere with the study specified assessments.

Prior treatment with apremilast, or participation in a clinical study involving apremilast.

Use of phototherapy (ie, UVB, UVA) or systemic immunosuppressive drugs (including, but not limited to, cyclosporine, corticosteroids, mycophenolate mofetil, azathioprine, Methotrexate, or tacrolimus), or oral preparations of herbal immunomodulatory medications within four weeks prior to Baseline/Randomization (Visit 2).

Use of interferon-γ within 12 weeks prior to Baseline/Randomization (Visit 2). Use of abatacept, adalimumab, certolizumab pegol, etanercept, golimumab, infliximab, or tocilizumab within 12 weeks prior to Baseline/Randomization (Visit 2).
