E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess if biosimilar infliximab (CT-P13) is non-inferior to innovator infliximab (INX) with regard to disease worsening in patients who have been on stable INX treatment for at least 6 months |
|
E.2.2 | Secondary objectives of the trial |
- To assess the safety and immunogenicity of CT-P13 compared to INX on patients who have been on stable INX treatment for at least 6 months
- To compare the efficacy of CT-P13 to INX in patients who have been on stable INX treatment for at least 6 months applying generic and disease-specific outcome measures
- To compare cost-effectiveness of CT-P13 to INX in patients who have been on stable INX treatment for at least 6 months |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. A clinical diagnosis of either rheumatoid arthritis, spondyloarthritis, psoriatic arthritis, ulcerative colitis, Crohn’s disease or chronic plaque psoriasis 2. Male or non-pregnant, non-nursing female 3. >18 years of age at screening 4. Stable treatment with innovator infliximab (Remicade) during the last 6 months 5. Subject capable of understanding and signing an informed consent form 6. Provision of written informed consent
|
|
E.4 | Principal exclusion criteria |
1. Major co-morbidities, such as severe malignancies, severe diabetic mellitus, severe infections, uncontrollable hypertension, severe cardiovascular disease (NYHA class 3 or 4) and/or severe respiratory diseases 2. Change of major co-medication during the last 2 months prior to randomization: RA, SpA and PsA: Initiation of systemic corticosteroids or synthetic DMARDs or other medication which according to the investigator would interfere with the stability of the disease. UC and CD: Initiation of systemic corticosteroids or an immunosuppressant or other medication which according to the investigator would interfere with the stability of the disease Psoriasis: Initiation of synthetic DMARDs or other medication which according to the investigator would interfere with the stability of the disease 3. Inadequate birth control, pregnancy, and/or breastfeeding 4. Psychiatric or mental disorders, alcohol abuse or other substance abuse, language barriers or other factors which makes adherence to the study protocol impossible 5. Change in treatment with innovator infliximab (Remicade) during the last 6 months due to disease related factors, not including dose/frequency adjustments due to drug concentration measurements 6. For patients with UC and CD: Functional colostomy or ileostomy. Extensive colonic resection with less than 25 cm of the colon left in situ. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Occurrence of disease worsening during the 52-week study period based on disease specific efficacy assessment scores.
A disease worsening in RA and PsA is defined as an increase in DAS28 of ≥ 1.2 from randomization and a minimum DAS score of 3.2.
A disease worsening in AS/SpA is defined as an increase in ASDAS of ≥1.1 from randomization and a minimum ASDAS of 2.1.
A disease worsening in ulcerative colitis is defined as an increase in Partial Mayo score of ≥ 3 points from randomization and a minimum partial Mayo score of ≥ 5 points.
A disease worsening in Crohn’s disease is defined as an increase in HBI of ≥ 4 points from randomization and a minimum HBI score of 7 points.
A disease worsening in psoriasis is defined as an increase in PASI of ≥ 3 points from randomization and a minimum PASI score of 5.
If a patient does not fulfill the formal definition, but experiences a clinically significant worsening according to both the investigator and patient and which leads to a major change in treatment this should be considered as a disease worsening but recorded separately in the CRF. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
52 weeks after randomization |
|
E.5.2 | Secondary end point(s) |
Generic: - Time from randomization to disease worsening - Patient and Physician Global assessment of disease activity - Occurrence of drug discontinuation - Time from randomization to drug discontinuation
Disease-specific: - Inflammation assessed by biochemical parameters - RA and PsA: DAS28, M-HAQ, RAID, PsAID - SpA: ASDAS, M-HAQ, BASDAI - Psoriasis: PASI, DLQI - UC: Partial Mayo score, IBDQ - CD: HBI, IBDQ
Exploratory endpoints: - EQ-5D - SF-36 - WPAI-GH - Use of health care resources
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The secondary endpoints will be evaluated at each visit from (and including) baseline to (and including) end of study at 52 weeks. The visits will be carried out according to the patient’s pre-randomization innovator infliximab treatment schedule, i.e. ranging from every 4 to 10 weeks. Time to event endpoints will be evaluated continously until 52 weeks after randomization. |
