E.3 | Principal inclusion criteria |
1. Must have met the eligibility criteria and have been enrolled in one of the two parent studies (APD334-301 or APD334-302) and also meet the following additional criteria: a. Subjects previously enrolled in Study APD334-301 must have either: I. Completed the Week 12 visit and have been assessed to have active UC that had deteriorated from baseline and meet one of the following criteria: • Absolute RB ≥ 2 on 2-consecutive days, and confirmation of ES ≥ 2 at or after the Week 12 assessment • Absolute RB + SF ≥ 4 on 2-consecutive days, and confirmation of ES ≥ 2 at or after the Week 12 assessment • Absolute RB ≥ 2 or RB + SF ≥ 4 (in any order) on 2-consecutive days, and confirmation of ES ≥ 2 at or after the Week 12 assessment or II. Completed the Week 52 visit Note: An endoscopic evaluation is required, however a proctosigmoidoscopy does not need to be repeated if performed within the last 4 weeks b. Subjects previously enrolled in APD334-302 must have completed the Week 12 visit 2. Eligible women of childbearing potential must fulfill the following: a. Have a negative urine beta human chorionic gonadotropin (β-hCG) pregnancy test b. Not breastfeeding 3. Both men and women subjects agree to use a highly effective method of birth control throughout the entire study period, from informed consent through the adverse event reporting period (30 days after the last dose of study treatment), if the possibility of conception exists. Eligible men and women subjects must also agree not to participate in a conception process (ie, actively attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization) during the study and for 30 days after the last dose of study treatment. Highly effective birth control methods include the following • Oral, implantable, or injectable contraceptives (starting ≥ 60 days before dosing) in combination with a diaphragm with vaginal spermicide, cervical cap with vaginal spermicide, or male condom; hormonal contraceptives (subjects should be consistently taking the hormonal contraceptive for at least 3 months [90 days] prior to the Eligibility assessment) • Standard intrauterine device (IUD; eg, Copper T 380A IUD), intrauterine system (IUS; eg, LNg 20 IUS - progesterone IUD), progesterone implant, or tubal sterilization (≥ 180 days after surgery) • Vasectomized male subjects using a condom, partner using diaphragm with spermicide, cervical cap with spermicide, estrogen and progesterone oral contraceptives (“the pill”), estrogen and progesterone transdermal patch, vaginal ring, or progesterone injection • Complete sexual abstinence defined as refraining from heterosexual intercourse for the entire period of risk associated with study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (calendar, symptothermal, post-ovulation methods) is not acceptable Note: Women who are surgically sterile or postmenopausal (defined as: 12 consecutive months with no menses without an alternative medical cause) are not considered to be of childbearing potential. If of childbearing potential, female partners of participating male subjects should agree to utilize a highly effective method of contraception for the duration of study participation. 4. Ability to provide written informed consent or assent (parent or legal guardian must provide consent for a subject < 18 years of age or as required per local regulations who has assented to participate in the study) and to be compliant with the schedule of protocol assessments |
|
E.4 | Principal exclusion criteria |
Subjects who meet ANY of the following exclusion criteria will NOT be eligible for enrollment into the study: 1. If the Investigator considers the subject to be unsuitable for any reason to participate in the OLE study
Exclusions related to general health: 2. Experienced an adverse event that led to discontinuation from parent etrasimod study 3. Day 1 pre-dose sitting vital sign assessment: heart rate < 50 bpm and systolic BP < 90 mm Hg 4. Day 1 pre-dose 12-lead electrocardiogram (ECG) in the supine position showing a second or third-degree AV block, periods of asystole > 3 seconds, PR interval > 200 ms, or QTcF ≥ 450 ms (males) or QTcF ≥ 470 ms (females) 5. Subjects requiring colectomy during the parent study 6. Subjects requiring treatment with prohibited medications as defined in the parent study
Exclusions related to laboratory results: 7. Laboratory values that meet study treatment discontinuation rules Note: In the case of any abnormal laboratory results, laboratory tests may be repeated once and if these results are within normal range, the subject is eligible for enrollment. |
