Phase 2

Completed

• Conditions: Rheumatoid Arthritis
• Interventions: Drug: Certolizumab Pegol

• Registration Number: NCT02293590
• Lead Sponsor: Rüdiger B. Müller

Brief Summary

Tight control of an adaptive concomitant treatment strategy after initiation of CZP will lead to an improved outcome of RA patients with an active disease despite DMARD treatment.

Detailed Description

Certolizumab pegol (CZP) is a tumor necrosis factor (TNF) antagonist which is marketed for the treatment of moderate to severe rheumatoid arthritis (RA) (Keystone, 2008) when given in combination with methotrexate (MTX). CZP is a PEGylated Fab' fragment of humanized anti-TNF antibody with a high affinity for TNF.

RA is a chronic inflammatory autoimmune disease with multiple treatment strategies and combination therapies available including analgesia, anti-inflammatory drugs and disease-modifying anti-rheumatic drugs. Previous trials have demonstrated positive results from the use of CZP but have compared its use to placebo in a fixed dose concomitant medication regime rather than using a more realistic dynamic treatment strategy normally employed in the clinical outpatient care of RA.

This trial is aimed at comparing the use of CZP in patients with moderate to severe RA when administered in conjunction with an intensive, adapted treatment strategy (Group A) versus a fixed-dosed program (Group B). CZP will be given in conjunction with MTX (a disease modifying anti-arthritic drug - or DMARD), steroidal therapy in the form of prednisolone and joint infiltrations of triamcinolone (another corticosteroid) and lidocaine (a pain therapy). Both treatment arms will include these concomitant medications but there will be an intensive adaptive approach adopted for the 'treat to target' population of Group A with a more fixed-dose approach set-out for Group B. Patients will be centrally randomized after screening to ensure a 50:50 ratio for both Groups in the study.

STUDY HYPOTHESIS

Tight control of an adaptive concomitant treatment strategy after initiation of CZP will lead to an improved outcome of RA patients with an active disease despite DMARD treatment.

2. Subjects with a history of cancer in the last 5 years, or with a current screening suspicious for cancer, other than non-melanoma skin cell cancers cured by local resection or carcinoma in situ
3. Subjects with evidence of untreated, active or latent bacterial (e.g. tuberculosis) or viral infections (e.g. Human Immunodeficiency Virus (HIV), Hepatitis B or C) at the time of potential enrolment
4. Subjects with any serious bacterial infection within the last 3 months, unless treated and resolved with antibiotics, or any untreated, chronic bacterial infection

Arm && Interventions

Group	Intervention	Description
fixed-dosed program	Certolizumab Pegol	Intervention: Certolizumab pegol (Cimzia (R), CZP) CZP of 400mg at Weeks 0, 2 and 4, followed by 200mg injections from Week 6, every 2 weeks until Week 24. DMARD: Patients are to continue to receive their stable weekly dose of DMARD as noted at study entry for the duration of the study (24 weeks) Glucocorticoids: Prednisolone (Spiricort (R)) daily dose of ≤ 10 mg Joint injections: None
intensive, adapted treatment strategy	Certolizumab Pegol	Experimental: intensive, adapted treatment strategy Certolizumab pegol (CZP, Cimzia (R)): 200mg every 2 weeks after loading d 400mg at Weeks 0, 2 and 4 DMARD: Patients without sufficient treatment response will be taken to the next step according to the therapeutic algorithm or next drug, for example: 15=\>25mg Metoject (R)/week =\> Leflunomide Gebro (R)20mg/d =\> Salazopyrine EN(R) 2000mg/d Glucocorticoids: At Week, 0 patients will be initiated on Spiricort (R) 20mg/d and tapered every 5 days Joint injections: Starting at Week 0 up to 5 joint injections may be conducted into synovitic joints at every visit of the study.

Secondary Outcome Measures

Name	Time	Method
To compare the proportion of patients reaching either a low disease activity status (LDAS) or a full remission of their RA across both treatment groups at weeks 8, 12, 18 and 24	weeks 8, 12, 18 and 24	Efficacy rates as measured by patients achieving Low DAS is defined (LDAS) or a full clinical remission according to the EULAR at weeks 8, 12, 18 and 24 weeks. LDAS as a DAS-28 score of less than 3.2.
