Trial Outcomes & Findings for A Study to Compare FKB327 Efficacy and Safety With Humira® in Rheumatoid Arthritis Patients (NCT NCT02260791)

NCT ID: NCT02260791

Last Updated: 2017-11-28

Results Overview

The primary efficacy endpoint was the ACR20 response rate at Week 24. An ACR20 response meant that the patient achieved a 20% improvement in Tender Joint Count and Swollen Joint Count and in at least 3 of the other 5 Core Data Set elements listed below. * Acute phase reactant (CRP) * Patient global assessment of disease activity * Physician global assessment of disease activity * Patient pain scale * Disability/functional questionnaire (patient completed Health Assessment Questionnaire Disability Index \[HAQ-DI\])

Participant Flow

Patients were enrolled in 109 sites in 12 countries in 3 geographical regions: North America, Europe and Rest of World. The first participant enrolled on 05 January 2015 and the last participant completed on 12 July 2016.

Screening details: Patients were randomised in a 1:1 ratio to receive either FKB327 40 mg eow or Humira 40 mg eow using the following stratification factors: prior biological treatment for Rheumatoid Arthritis (RA) (yes/no) and Screening disease activity (DAS28-CRP ≤5.1/\>5.1).

PRIMARY outcome

Timeframe: Week 24

Population: The Full Analysis Set (FAS) was defined as the set of patients who received at least 1 dose of the randomised treatment and who had at least 1 evaluable primary efficacy measurement after their first dose of randomised treatment. Patients were analysed according to the randomised treatment in the primary analysis.

The primary efficacy endpoint was the ACR20 response rate at Week 24. An ACR20 response meant that the patient achieved a 20% improvement in Tender Joint Count and Swollen Joint Count and in at least 3 of the other 5 Core Data Set elements listed below. * Acute phase reactant (CRP) * Patient global assessment of disease activity * Physician global assessment of disease activity * Patient pain scale * Disability/functional questionnaire (patient completed Health Assessment Questionnaire Disability Index \[HAQ-DI\])

Population: The Full Analysis Set (FAS) was defined as the set of patients who received at least 1 dose of the randomised treatment and who had at least 1 evaluable primary efficacy measurement after their first dose of randomised treatment. Patients were analysed according to the randomised treatment in the primary analysis.

The DAS28-CRP assessment involved evaluating the number of tender (TJC) and swollen (SJC) joints (out of 28 specified joints), serum CRP, and patient global assessment of disease activity (VAS from 0 to 100, very well to extremely bad). The DAS28-CRP is a number on a scale from 0 to 10 indicating the current activity of the patient's RA. A higher score indicates higher disease activity.

Patients were analysed according to the randomised treatment in the primary analysis.

Counts of swollen joints from amongst 66 selected joints performed by a trained and qualified joint assessor using standardised techniques recommended by the European League Against Rheumatism (EULAR). Joints were classified as swollen/not swollen giving a total possible swollen joint count score of 0 to 66 with higher scores indicating severe disease. Swollen joint count is a value of the individual ACR core set variables.

Analysis of serum C-Reactive Protein (CRP) concentrations for inclusion in the ACR20/50/70 and DAS28-CRP scores was performed by a central laboratory. Elevation of CRP is a nonspecific marker of inflammation. Values above 10 mg/L were considered to be abnormally high. Decrease in level of CRP indicates reduction in inflammation.

Patient assessment of disease activity visual analogue scale (VAS) will be assessed on 100-point scales (ranging from very well (0) to extremely bad (100)).The patient assessment of disease activity VAS will contribute to the calculation of the DAS28 score. The patient assessment of disease activity VAS will contribute to the calculation of ACR20, ACR50 and ACR70 response.

An injection site pain visual analogue score (VAS) will be administered to the patient. To determine the extent of the pain, patients will be asked to place a small vertical mark on a horizontal scale from 0 to 100, the ends of which are labelled with the extreme responses to be measured ("No pain" at 0 and "Intolerable pain" at 100). Patient's assessment of pain is a value of the individual ACR core set variables.

The HAQ-DI is a 20-question, self-administered instrument that measures the patient's functional ability on a 4-level difficulty scale (0 to 3, with 0 representing normal or no difficulty and 3 representing inability to perform). Eight categories of functioning are included: dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. This scale is sensitive to change and is a good predictor of future disability. HAQ-DI is a value of the individual ACR core set variables.

Timeframe: Baseline and Week 24

Population: The Full Analysis Set (FAS) was defined as the set of patients who received at least 1 dose of the randomised treatment and who had at least 1 evaluable primary efficacy measurement after their first dose of randomised treatment. Patients were analysed according to the randomised treatment in the primary analysis.

The DAS28 score is a combined index that has been developed to measure the disease activity in patients with RA and has been extensively validated for its use in clinical studies. The DAS28-CRP assessment involved evaluating the number of tender (TJC) and swollen (SJC) joints (out of 28 specified joints), serum CRP, and patient global assessment of disease activity (VAS from 0 to 100, very well to extremely bad). The individual results are summed using a formula. The DAS28 is a number on a scale from 0 to 10 indicating the current activity of the patient's RA. A higher score indicates higher disease activity.
