E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety and efficacy of RPC1063 for the treatment of patients with moderate to severe ulcerative colitits |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Previously participated in a trial of RPC1063 for UC and meet the criteria for participation in the open label extension as outlined in the prior trial
2. Female patients of childbearing potential:
Must agree to practice a highly effective method of contraception throughout the trial until completion of the 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
sexual abstinence
Male patients:
Must agree to use a latex condom during sexual contact with women of childbearing potential while participating in the trial until completion of the safety follow-up visit.
All patients:
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
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. |

• Treatment with a biologic agent
• Treatment with an investigational agent other than RPC1063
• Treatment with D-penicillamine, leflunomide, thalidomide, natalizumab or fingolimod
• Treatment with lymphocyte-depleting therapies (e.g., Campath, anti-CD4, cladribine, rituximab, ocrelizumab, cyclophosphamide, mitoxantrone, total body irradiation, bone marrow transplantation, alemtuzumab, daclizumab)
• Treatment with a live vaccine within 4 weeks prior to Visit 1 of this trial
2. Are currently receiving or require initiation of any of the following therapies:
• Treatment with corticosteroids at a dose that exceeds the prednisone equivalent of >40 mg
• Treatment with immunosuppressive agents (e.g., azathioprine, 6-MP, or methotrexate)
• Chronic non-steroidal anti-inflammatory drug (NSAID) use (Note: occasional use of NSAIDs and acetaminophen [eg, headache, arthritis, myalgias, or menstrual cramps] and aspirin up to 325 mg/day is permitted)
• Treatment with Class Ia or Class III anti-arrhythmic drugs or treatment with two or more agents in combination known to prolong PR interval
Exclusions Related to General Health:
3. Pregnancy, lactation, or a positive serum beta human chorionic gonadotropin (hCG)
4. 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
5. 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:
6. 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
7. FEV1 or FVC < 50% of predicted values |

E.5 End points |
E.5.1 | 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, and TEAEs of special interest will be summarized, as well as changes from Baseline for clinical laboratory measures, vital signs, ECGs, and pulmonary function tests. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Efficacy assessments will be performed at the following visits;
Day 1 (Baseline/Visit 1) - All
Week 5 (Visit 2)
Week 10 (Visit 3)
Week 16 (Visit 4)
Week 22 (Visit 5)
Thereafter, additional visits at 12-week intervals (Visit 5 onwards).
Partial Mayo partial score assessment to be performed at each visit.
Full Mayo score assessment performed at Visit 1, Visit 7, at each additional visit (12-week intervals), and at the End of Treatment/Early Termination Visit.
Endoscopy and colonic biopsies will be performed at Week 1, Visit 7, at each additional visit (12-week intervals), and at the End of Treatment/Early Termination Visit. |
