Detaillierte Beschreibung

A Phase II/III Randomized, Double-blind, Placebo-controlled, Multicenter Study to Determine the Efficacy and Safety of ABC008 in the Treatment of Subjects with Inclusion Body Myositis Detailed Description: A Phase II/III Randomized, Double-blind, Placebo-controlled, Multicenter Study to Determine the Efficacy and Safety of ABC008 in the Treatment of Subjects with Inclusion Body Myositis Detailed Description: This is a Phase II/III randomized, double-blind, placebo-controlled, parallel multicenter study with 3 parts.

The study will include a sentinel cohort (Part A) of 30 subjects who will receive first three doses of the study drug. Safety data from subjects in the sentinel cohorts will be evaluated by a Data and Safety Monitoring Board (DSMB) before further dosing of the sentinel cohort, as well as initiation of enrollment in the double-blind safety and efficacy cohort (Part B). After completion of Part A or Part B, subjects have the option of enrolling in an open-label long-term extension study or progressing to the pharmacodynamics (PD) recovery cohort (Part C), to evaluate the recovery of the depletion of killer cell lectin-like receptor G1 (KLRG1)+ cells after the end of treatment with ABC008.

Efficacy, safety, HRQoL, and HRU assessments will be conducted. Blood samples will be obtained to evaluate the serum PK, PD, and immunogenicity of ABC008 throughout the study.

Part A: Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Zeitfenster: Up to Week 80

An adverse event (AE) was defined as any untoward medical occurrence in any participant participating in a clinical investigation, regardless of the suspected cause. An AE was therefore any unfavorable and unintended sign, symptom, disease, concurrent illness, or clinically significant abnormal laboratory finding that emerged or worsened during the study. A TEAE was defined as an AE that first occurred or worsened after initiation of study drug.

Up to Week 80
Part A: Number of Participants With TEAEs by Severity
Zeitfenster: Up to Week 80

A TEAE was defined as an AE that first occurred or worsened after initiation of study drug and was graded by severity per protocol-specified Common Terminology Criteria for Adverse Events (CTCAE) criteria: Grade 1, Mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2, Moderate (minimal, local, or noninvasive intervention indicated; limited age-appropriate instrumental activities of daily living (ADL)); Grade 3, Severe or medically significant (medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; or limiting self-care ADL); Grade 4, Life-threatening (threatening consequences; urgent intervention indicated); and Grade 5, Death (death related to an AE).

Up to Week 80
Part A: Number of Participants With TEAEs Related to Study Drug
Zeitfenster: Up to Week 80

An AE was defined as any untoward medical occurrence in any participant participating in a clinical investigation, regardless of the suspected cause. An AE was therefore can be any unfavorable and unintended sign, symptom, disease, concurrent illness, or clinically significant abnormal laboratory finding that emerged or worsened during the study. A TEAE was defined as an AE that first occurred or worsened after initiation of study drug. An AE with missing relationship to study drug was considered as related to study drug.

Part A: Mean Change From Baseline in the Inclusion Body Myositis Functional Rating Scale (IBMFRS) Total Score at Week 76
Zeitfenster: Baseline (Day 1) and at Week 76

The IBMFRS was used as an ordinal rating scale to determine participant's assessments of their capabilities. It included 10 measures (swallowing, handwriting, cutting food and handling utensils, fine motor tasks, dressing, hygiene, turning in bed and adjusting covers, changing position from sitting to standing, walking, and climbing stairs) graded on a Likert scale (a psychometric tool) from 0 (being unable to perform) to 4 (normal). The sum of the 10 items provided a value between 0 and 40, with a higher score representing less functional limitation or better functional status. Baseline value was defined as the last non-missing valid value prior to first administration of study treatment (on Day 1). Change from Baseline was calculated as the data collected at post-randomization visits minus the Baseline.

Part A and B: Mean Change From Baseline in Modified Timed Up and Go Test (mTUG) at Week 76
Zeitfenster: Baseline (Day 1) and up to Week 76

The mTUG assessed functional mobility by measuring the time required for a participant to rise from a standard armchair, walk 3 meters, turn around, walk back to the chair, and sit down (assistive devices permitted after standing, but no support from a caregiver, or a wall). Negative values indicated faster performance and positive values indicated slower performance. Baseline value was defined as the last non-missing valid value prior to first administration of study treatment (on Day 1). Change from Baseline was calculated as the data collected at post-randomization visits minus the Baseline.
