Trial Outcomes & Findings for A Study To Evaluate Efficacy, Safety, Pharmacokinetics, And Pharmacodynamics Of Satralizumab In Patients With Generalized Myasthenia Gravis (NCT NCT04963270)

NCT ID: NCT04963270

Last Updated: 2025-02-28

Results Overview

The MG-ADL scale was used to assess the degree of gMG symptoms (six items: diplopia, ptosis, difficulties with chewing, swallowing, talking, and respiratory problems) and functional limitations in carrying out activities of daily living (two items: ability to brush teeth or comb hair and impairment in the ability to arise from a chair) that are present and clinically relevant in gMG participants. Each of the eight items was ranked on a 0-3 scale, with 3 representing the most severe symptoms or impaired performance and 0 representing no symptoms or impaired performance. The total MG-ADL score was calculated as the sum of each item score, with a maximum score ranging from 0 (least severe symptoms/impairment) to 24 (most severe symptoms/impairment). Higher scores indicate greater disease severity.

Participant Flow

A total of 188 participants with generalized myasthenia gravis (gMG) took part in the study across 76 investigational sites in 17 countries. Of the 188, 2 adolescent participants were randomized after the last adult participant was enrolled in the study and therefore were not part of efficacy analysis.

The study consists of 2 periods: Double-blind (DB) period where participants were randomized in a 1:1 ratio to receive either satralizumab or matching placebo and an open-label extension (OLE) period where all participants who completed the DB period received satralizumab. Participants were on a stable dose of background therapy (for gMG) throughout the DB period and until Week 12 of the OLE period.

Measure
Placebo
Participants received satralizumab matched placebo, subcutaneously (SC), at Weeks 0, 2, 4, and every 4 weeks (Q4W) thereafter until the end of the DB period.
Satralizumab
Participants received satralizumab 120 (milligrams) mg or 180 mg, based on body weight, SC, at Weeks 0, 2, 4 (loading doses), and Q4W (maintenance doses) thereafter until the end of the DB period.
Placebo (DB) to Satralizumab (OLE)
After completion of the DB period, participants entered the OLE period where they received satralizumab, 120 mg or 180 mg, based on body weight, SC at Weeks 0, 2, and 4 (loading doses), and Q4W thereafter (maintenance doses) during the OLE period.
Satralizumab (DB) to Satralizumab (OLE)
After completion of the DB period, participants entered the OLE period and continued receiving satralizumab 120 mg or 180 mg, based on body weight, SC until the end of the OLE period. Participants received a placebo injection on Week 2 of OLE to maintain blinding to DB treatment assignment.

Population: AChR+ population included all participants in the study who were AChR+.

The MG-ADL scale was used to assess the degree of gMG symptoms (six items: diplopia, ptosis, difficulties with chewing, swallowing, talking, and respiratory problems) and functional limitations in carrying out activities of daily living (two items: ability to brush teeth or comb hair and impairment in the ability to arise from a chair) that are present and clinically relevant in gMG participants. Each of the eight items was ranked on a 0-3 scale, with 3 representing the most severe symptoms or impaired performance and 0 representing no symptoms or impaired performance. The total MG-ADL score was calculated as the sum of each item score, with a maximum score ranging from 0 (least severe symptoms/impairment) to 24 (most severe symptoms/impairment). Higher scores indicate greater disease severity.

The QMG is a 13-item direct physician assessment scoring system that quantifies disease severity based on impairments of body functions and structures. The 13-items are: ptosis, diplopia, orbicularis oculi weakness, swallowing, speech disruption, percent forced vital capacity, arm and leg endurance (four items), grip strength (two items), and neck flexion strength. Each of the 13 item was quantitatively assessed and scored on a scale from 0=None to 3=Severe, providing a total QMG score (sum of each item score) ranging from 0 to 39 where higher scores indicate greater disease severity.

The MG-QOL-15r is a disease-specific health-related QoL measure that consists of 15 items: mobility (9 items), symptoms (3 items), and contentment and emotional well-being (3 items). Items were scored on a scale from 0=Not at all to 2=Very much with the total score ranging from 0 to 30 and higher scores indicate worse health-related quality of life (HRQoL).

The Neuro-QoL is a validated tool designed to evaluate the HRQoL in participants with chronic neurological disease. The Fatigue Subscale is implemented as an eight-item, stand-alone short form that assesses the multi-dimensional aspects of fatigue ranging from general tiredness to debilitating exhaustion that Impacts activities of daily living. Each item was assessed using a 5-level Likert scale ranging between 1=never to 5=always. Raw scores range from 8 to 40, higher values indicate greater fatigue.

The QMG is a 13-item direct physician assessment scoring system that quantifies disease severity based on impairments of body functions and structures. The 13-items are: ptosis, diplopia, orbicularis oculi weakness, swallowing, speech disruption, percent forced vital capacity, arm and leg endurance (four items), grip strength (two items), and neck flexion strength. Each of the 13 item was quantitatively assessed and scored on a scale from 0=None to 3=Severe, providing a total QMG score (sum of each item score) ranging from 0 to 39 where higher scores indicate greater disease severity.

The MG-ADL scale was used to assess the degree of gMG symptoms (six items: diplopia, ptosis, difficulties with chewing, swallowing, talking, and respiratory problems) and functional limitations in carrying out activities of daily living (two items: ability to brush teeth or comb hair and impairment in the ability to arise from a chair) that are present and clinically relevant in gMG participants. Each of the eight items was ranked on a 0-3 scale, with 3 representing the most severe symptoms or impaired performance and 0 representing no symptoms or impaired performance. The total MG-ADL score was calculated as the sum of each item score, with a maximum score ranging from 0 (least severe symptoms/impairment) to 24 (most severe symptoms/impairment). Higher scores indicate greater disease severity.

SECONDARY outcome

Timeframe: Baseline to Week 24

Population: Immunogenicity-analysis population included all participants randomly assigned to study treatment who received any study treatment with at least one post-dose anti-drug antibody (ADA) assessment. Overall number analyzed is the number of participants with data available for analysis.

The percentage of ADA-positive participants after drug administration were determined for participants exposed to satralizumab. For determining post-baseline incidence, participants were considered to be ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following study drug exposure, or if they were ADA-positive at baseline and the titer of 1 or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the baseline titer result. Participants were considered to be ADA-negative if they were ADA-negative or had missing data at baseline and all post-baseline samples were negative, or if they were ADA positive at baseline but did not have any post-baseline samples with a titer that is at least 4-fold (0.60 titer unit) greater than the titer of the baseline sample.
