Condition(s) targeted: Rheumatoid Arthritis

Intervention: Infliximab Increased Frequency (Drug); Infliximab Increased Dose (Drug); Infliximab Control (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Merck Sharp & Dohme Corp.

Summary

This Phase IIIb, randomized, multi-national, multi-center, blinded study of Infliximab (IFX) in subjects aged 18 and older with active RA is being conducted to assess whether increasing either the infusion dose or infusion frequency in patients presenting with a disease flare after an initial response to infliximab results in a significant improvement in disease activity. Subjects responding to an initial infliximab treatment regimen, who flare during continuation of treatment at 3 mg/kg administered every 8 weeks, will be randomly assigned to one of 3 different dosing regimens of infliximab and will be treated for 4 or 5 consecutive infusions for a total duration of 24 weeks. The infliximab control group and the infliximab increased dose group are evaluator and subject-blinded. The increased frequency group is not blinded. Clinical assessments of disease activity will be based the European League Against Rheumatism (EULAR) criteria for response. Safety parameters will be assessed at every infusion. A disease flare is defined by an increase in DAS28 with 0. 6 or more at screening, when compared to the DAS28 score measured immediately prior to the last Remicade® infusion and depends upon the actual score as well. Since prior to enrollment, the subject received Remicade® as per routine clinical practice, the days on which infusions were administered and assessments are done during the induction period do not have to be exactly at Week 2, 6 and 14.

Clinical Details

Official title: Randomised Controlled Trial Evaluating Strategies to Optimize Disease Activity Control in RA Patients Treated With Infliximab in Clinical Practice.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change in Disease Activity Score Based on 28 Joint Count (DAS28) Score.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- aged 18 years or more

- with RA according to ACR criteria

- presented with a disease flare after initial response to infliximab, with both

response and flare being defined using the DAS28 score (EULAR criteria)

- received the standard Remicade® dosing schedule per the EU label (3 mg/kg at Weeks 0,

2, 6, [and 14])

- an initial response documented by moderate or good DAS28 improvement (EULAR criteria)

from Week 0 to Week 6 or 14. Exclusion Criteria:

- a female who is, or intends to become, pregnant during or within 6 months of the end

of the study, is nursing or not using adequate contraceptive measures

- has not observed the designated periods for concomitant medications

- used any investigational medical product within 30 days prior to Baseline

- any clinically significant deviation from normal in the physical examination or chest

X-ray that in the investigator's judgment, may interfere with the study evaluation or affect subject safety

- rheumatic disease other than RA or has any systemic inflammatory condition with signs

and symptoms that might confound the evaluations of safety and toxicity

- allergic reaction/sensitivity to the study drug or its excipients that requires

corticosteroid pre-infusion medication.
