Key inclusion & exclusion criteria

Inclusion criteria:
1. Previously participated in a trial of RPC1063 (eg, RPC01-3101 or completed at least 1 year of the open-label period for RPC01-202) and meet the criteria for participation in the open label extension as outlined in the prior trial
2. Female patients of childbearing potential (FCBP)*:
Must agree to practice a highly effective method of contraception**
throughout the trial until completion of the 90-day safety follow-up visit. Highly
effective methods of contraception are those that alone or in
combination result in a failure rate of a Pearl index of less than 1% per
year when used consistently and correctly. Acceptable methods of birth
control in the trial are the following:
combined hormonal (oestrogen and progestogen containing)
contraception, which may be oral, intravaginal, or transdermal
progestogen-only hormonal contraception associated with inhibition of
ovulation, which may be oral, injectable, or implantable
placement of an intrauterine device (IUD)
placement of an intrauterine hormone-releasing system (IUS)
bilateral tubal occlusion
vasectomised partner
complete sexual abstinence

*For the purposes of this study, a female patient is considered to be of childbearing potential if she has reached menarche, and 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)
Contraception Education: Counselling about pregnancy precautions and the potential risks of fetal exposure must be conducted for FCBP.
The Investigator will educate all FCBP about the different options of contraceptive methods or abstinence, as appropriate, at the Screening
and Baseline Visits. The patient will be re-educated every time her contraceptive measures/methods or ability to become pregnant changes. The female patient's chosen form of contraception must be effective by the time the female patient is randomized into the study (for example, hormonal contraception should be initiated at least 28 days before baseline).

Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception.
3. Must provide written informed consent and have the ability to be compliant with the schedule of protocol assessments, which must be obtained prior to any trial-related procedures.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 1164

• Treatment with Class Ia or Class III anti-arrhythmic drugs or
treatment with two or more agents in combination known to prolong PR interval.
3. Are receiving treatment with any of the following drugs or interventions within the corresponding timeframe:
At Day 1
- CYP2C8 inhibitors (eg, gemfibrozil or clopidogrel) or inducers (eg, rifampicin)
Two weeks prior to Day 1
- Monoamine oxidase inhibotors (eg, selegiline, phenelzine)
4. Are receiving treatment with breast cancer resistance protein (BCRP) inhibitors (eg, cyclosporine, eltrombopag)
Exclusions Related to General Health:
5. Pregnancy, lactation, or a positive serum beta human chorionic gonadotropin (hCG)
6. Clinically relevant hepatic, neurological, pulmonary, ophthalmological, endocrine, psychiatric or other major systemic disease making implementation of the protocol or interpretation of the trial difficult or that would put the patient at risk by participating in the trial or that would have required a patient to discontinue treatment in previous RPC1063 trial
7. Clinically relevant cardiovascular conditions, including history or presence of recent myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, Class III/IV heart failure, sick sinus syndrome, or severe untreated sleep apnea

Exclusions Related to Laboratory Results:
8. Liver function impairment or persisting elevations of aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 5 times the upper limit of normal (ULN), or direct bilirubin > 3 times the ULN
9. FEV1 or FVC < 50% of predicted values

Primary Outcome(s)

Primary end point(s): Due to the open-label nature of the trial and the lack of a control group, all data will be summarized and no hypothesis testing will be performed. Each efficacy endpoint will be summarized and 95% confidence intervals around the estimates may also be presented.

Efficacy Endpoints:
• Proportion of patients in clinical remission.
• Proportion of patients with a clinical response
• Proportion of patients with endoscopic improvement
• Proportion of patients with mucosal healing
• Proportion of patients with corticosteroid-free remission
• Change from Baseline in complete Mayo score, partial Mayo score, and 9-point Mayo score
• Proportion of patients with histologic remission
• Proportion of patients with clinical response, clinical remission, or endoscopic improvement in patients who had previously received anti-TNF therapy

Safety Endpoints:
- The incidence, severity, and relationship of treatment-emergent
adverse events (TEAEs), serious AEs (SAEs), TEAEs leading to
discontinuation of investigational drug, AEs of special interest (AESIs),
and TEAEs of special interest will be summarized.
- Exploratory safety endpoints include changes from baseline for clinical laboratory measures, vital signs, ECGs, and pulmonary function tests.

Other Exploratory Endpoints:
- Absolute lymphocyte count (ALC) derived from hematology laboratory results
- Blood biomarkers (cytokines, chemokines, other markers of inflammation)
- Stool biomarkers (eg FCP)
- Mucosal tissue blood biomarkers (eg, lymphocyte subsets)
- Exploratory measurements of immune response (e.g. SARS-CoV-2 serology), from blood samples (processed for serum only) collected after the amendment, every 48 weeks thereafter and end of treatment, and the potential association between these measurements and selected endpoints related to safety, efficacy, and/or biomarkers.

Main Objective: To evaluate the long-term safety and efficacy of RPC1063 for the treatment of all patients with moderate to severe UC
To evaluate the long-term efficacy of RPC1063 for the treatment of adult patients with moderate to severe UC.

Week 5 (Visit 2)
Week 10 (Visit 3)
Week 16 (Visit 4)
