Trial Outcomes & Findings for An Open-Label Study of RoActemra/Actemra (Tocilizumab) in Patients With Moderate to Severe Active Rheumatoid Arthritis (NCT NCT01951170)

NCT ID: NCT01951170

Last Updated: 2016-09-21

Results Overview

The mTSS is a measure of joint damage that combines scores for bone erosion and joint-space narrowing (JNS). Erosion score: A total of 14 locations in each hand and wrist and 6 joints in the foot were evaluated for erosion using an 8-point scale where 0=normal to 3.5=very severe erosion. JNS score: A total of 13 locations in each hand and wrist and 6 joints in the foot were evaluated for joint narrowing score using a 9-point scale where 0=normal to 4.0=definite ankylosis (stiffness or fixation of a joint). mTSS scores ranged from 0 (normal) to 292 (worst possible total score). Change from baseline = mTSS score at Week 24 minus score at baseline. An increase in mTSS from baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.

Population: Full Analysis Set (FAS) included all enrolled participants who received at least one dose of subcutaneous tocilizumab. Here, the number analyzed represents the number of participants for whom the Week 24 X-ray was performed.

The mTSS is a measure of joint damage that combines scores for bone erosion and joint-space narrowing (JNS). Erosion score: A total of 14 locations in each hand and wrist and 6 joints in the foot were evaluated for erosion using an 8-point scale where 0=normal to 3.5=very severe erosion. JNS score: A total of 13 locations in each hand and wrist and 6 joints in the foot were evaluated for joint narrowing score using a 9-point scale where 0=normal to 4.0=definite ankylosis (stiffness or fixation of a joint). mTSS scores ranged from 0 (normal) to 292 (worst possible total score). Change from baseline = mTSS score at Week 24 minus score at baseline. An increase in mTSS from baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.

The DAS28 score is a measure of the patient's disease activity calculated using the tender joint count of 28 joints (TJC28), swollen joint count of 28 joints (SJC28), patient's global assessment of disease activity visual analog scale (PGA VAS) with 0=no disease activity to 100=maximum disease activity displayed on the 100-millimeter (mm) horizontal VAS and the erythrocyte sedimentation rate (ESR) for a total possible score of 0 to 10. Higher scores represent higher disease activity. DAS28-ESR remission is defined as a score \< 2.6.

A positive ACR20 response requires at least 20% improvement compared to baseline in SJC (66 joints) and TJC (68 joints) as well as at least 20% improvement in 3 of the following 5 assessments: 1) PGA pain VAS, 2) PGA VAS; 3) physician's global assessment of disease activity VAS, 4) Health Assessment Questionnaire-Disability Index (HAQ-DI) with 20 questions consisting of 8 components: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities, 0=without difficulty to 3=unable to do; and 5) acute phase reactant (C-reactive protein \[CRP\] - if not available, ESR was used). ACR50 and ACR70 responses are defined in a similar way except that they required a 50% and 70% improvement from baseline, respectively. VAS range for all assessments was 0=no disease activity to 100=maximum disease activity.

PGA VAS is the participant's overall assessment of their current disease activity. The disease activity is displayed on a 100-mm horizontal VAS. The left-hand extreme (0 mm) of the line is described as "no disease activity" (symptom free and no arthritis symptoms) and the right-hand extreme (100 mm) is described as "maximum disease activity" (maximum arthritis disease activity). The change in PGA VAS is determined as the difference in values from baseline. A negative change from baseline indicates improvement.

HAQ-DI is the participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty. A negative change from baseline indicates improvement.

The FACIT measurement system is a collection of health-related quality of life questionnaires targeted to the management of chronic illness and includes questions on physical well-being, social/family well-being, emotional well-being and functional well-being. The FACIT-F Scale measures an individual's level of fatigue during their usual daily activities. Total scores range from 0 to 52 with lower scores representing greater fatigue, and scores below 30 representing severe fatigue. A positive change from baseline indicates improvement.

The SDAI is a combined index for measuring disease activity in rheumatoid arthritis and calculated as SDAI = TJC28 + SJC28 + PGA VAS (in mm) + Physician Global Assessment of Disease Activity VAS (in mm) + C reactive protein (CRP) in milligrams/deciliter (mg/dL) with a total SDAI score ranging from 0 to 86. Higher scores indicate greater disease activity. The SDAI scale is divided into the following categories: Clinical remission = score ≤ 3.3; Low disease activity = score \> 3.3 and ≤ 11.0; Moderate disease activity = score \> 11.0 and ≤ 26.0; Severe disease = score \> 26.0.

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
