E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To describe the peak levels, trough levels and AUC of the following golimumab regimens: 50 mg every month, and 100 mg every one-and-a-half month and 100 mg every two months, in patients with a rheumatic disease. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the efficacy of the two 100mg regimens by changes in disease activity (DAS28-CRP, ASDAS, PASDAS) compared to 50mg every month; • To identify the proportion of patients with undetectable golimumab levels and / or antibodies to golimumab; • To assess the incidence of AEs, with special interest to injection site reactions; • To establish which regimen is preferred by patients: 50 mg every month or 100 mg every one-and-a-half month or two months.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Rheumatoid arthritis, psoriatic arthritis or axial spondyloarthritis by fulfilling one of the following: o Rheumatoid arthritis: either 2010 ACR RA13 and/or 1987 RA14 criteria and/or clinical diagnosis of the treating rheumatologist; o Psoriatic arthritis: Classification Criteria for Psoriatic Arthritis (CASPAR)15 and/or diagnosed with peripheral SpA of the psoriatic arthritis subtype by a rheumatologist; o Axial spondyloarthritis: Assessment of SpondyloArthritis international Society (ASAS) classification criteria16 and/or clinical diagnosis of the treating rheuma-tologist; • Patients using golimumab in the standard dose of 50mg every month for at least three months with a good clinical response, defined as DAS28-CRP ≤ 2.6 for RA, or PASDAS ≤ 3.2 (PsA) or ASDAS < 2.1; • Patient informed consent, ≥16 years old and mentally competent; • Ability to measure the outcome of the study in this patient (e.g. patient availability; willing and being able to undergo repeated serum samples); • Ability to read and communicate well in Dutch. |

E.5 End points |
E.5.1 | Primary end point(s) |
The main aim of the study is to describe peak levels, trough levels and area-under-the-curve of golimumab 50 mg every month, 100 mg every one-and-a-half month and 100 mg every two months. To measure these parameters, blood samples will be drawn at twelve points during the study. Samples will then be analysed using a validated bioanalytical assay for golimumab in serum at the bioanalytical laboratory of Sanquin. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Twelve points in time over eight months (4 in the 1st month, 2 in the 3rd month, 2 in the 4th month, 1 in the 6th month, 1 in the 7th month en 2 in the eighth month) |
|
E.5.2 | Secondary end point(s) |
Efficacy Disease activity will be measured at maximum one week before or after every second trough level sampling day, to be able to compare the three regimes in efficacy. Disease activity will be measured using the DAS28-CRP for RA, using the PASDAS for PsA and using the ASDAS for axSpA. Therefore, the following outcomes will be collected: - Acute phase reactants: CRP (for RA, PsA and axSpA) and ESR (axSpA); - Physician Global Assessment of disease activity (PsA); - Patient Global Assessment of disease activity (RA, PsA, axSpA); - BASDAI/ASDAS-questionnaire (axSpA); - SF-12 questionnaire (PsA); - Physical examination: tender joint count (RA, PsA), swollen joint count (RA, PsA), dactylitis and enthesitis (using the Leeds Enthesitis Index (PsA)). The acute phase reactants analysis will be performed in the laboratory of the Canisius Wilhelmina Hospital, located in the Sint Maartenskliniek.
Antibodies Presence of anti-drug antibodies against golimumab will be measured in the proportion of patients with undetectable golimumab levels. This means that in patients with golimumab levels < 0.1 mg/L17 anti-drug antibodies will be measured in serum. Samples will then be analysed using a validated ADA radio-immune assay at the bioanalytical laboratory of Sanquin.
Adverse events The occurrence of adverse events during the study period will be registered using the Common Toxicity Criteria for Adverse Events (CTCAE). [BRON] For injection site reactions, a list with symptoms associated to injection site reactions will be used, for example local redness and itches.
Regime preference At the last study visit, patients will be asked which medication regimen they preferred. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Adverse events and efficacy at the 4th, 8th and 12th visit Regime preference at the 12th visit Antibody development can be checked for every blood sample of golimumab, when concentration is < 0.1 mg/L |
