E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The overall objectives of the study are to evaluate long-term safety of CTP-543 and to assess long-term effects of CTP-543 on treating hair loss in adult patients with moderate to severe alopecia areata |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Written informed consent, and authorization for release and use of protected health information. 2.Have completed a 24-week Treatment Period in a previous qualifying CTP-543 clinical trial. 3.Female subjects are eligible to participate if at least one of the following conditions applies: a)Is a woman of childbearing potential (WOCBP) and using a medically highly effective form of birth control with a failure rate less than 1% per year from at least 4 weeks prior to Baseline until at least 30 days following last dose of study drug. Examples of medically highly effective birth control methods include: i.Combined (estrogen and progestogen containing) hormonal contraception (oral, patch, vaginal ring) ii.Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable) iii.Intrauterine device or intrauterine hormone-releasing system iv.Bilateral tubal occlusion v.Vasectomized partner (partner is the sole sexual partner of the WOCBP trial participant and the vasectomized partner has received medical assessment of the surgical success) vi.Sexual abstinence (reliable as refraining from heterosexual intercourse during the above-mentioned period) b) Is not a WOCBP: i. Premenopausal with one of the following: a. Documented hysterectomy; b. Documented bilateral salpingectomy; c. Documented bilateral oophorectomy. ii. Postmenopausal (cessation of menses for at least 12 months prior to screening) Postmenopausal is defined as no menses for 12 months without an alternative medical cause. In addition, a high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm postmenopausal in women under 60 years old and not using hormonal contraception or hormone replacement therapy (HRT). However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. Females on HRT and whose menopausal status is in doubt will be required to use one of the nonestrogen hormonal highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment 4.Male participants must: a.Agree to use, with their partners, male contraception (condom) and one of the highly effective contraceptive methods listed in Inclusion Criterion 3, from Baseline until at least 90 days following last dose of study drug. b.Refrain from donating sperm during the study and for at least 90 days after the end of the study. 5.Willing to comply with the study visits and requirements of the study protocol.

E.4 | Principal exclusion criteria |
1.Active scalp inflammation, psoriasis, or seborrheic dermatitis requiring topical treatment to the scalp, significant trauma to the scalp, or other scalp condition that may interfere with the SALT assessment, or untreated actinic keratosis anywhere on the body. 2.Females who are nursing, pregnant, or planning to become pregnant while in the study, and for 30 days after last dose of study medication. 3.Donation of blood at any point throughout the study and for 30 days after last dose of study medication. 4.Most recent hematologic parameters do not permit continued dosing; i.e., criteria for withholding IP have been met and have not recovered to values required to resume dosing. 5.Any medical, psychiatric, or social condition that is likely to unfavorably affect the risk-benefit of continued study participation, interfere with study compliance, or confound safety or efficacy assessments. |

E.5 End points |
E.5.1 | Primary end point(s) |
Safety of CTP-543 will be assessed by evaluating adverse event, clinical laboratories, physical examinations, vital signs, concomitant medications, and electrocardiogram results. Efficacy of CTP-543 will include all patients who receive study drug and have at least 1 post-treatment SALT assessment in this study. Relative change in SALT score over time will be summarized descriptively by visit, as appropriate. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After at least 1 post-treatment SALT assessment (week 4) in this study |
