상세 설명

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.

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
기간: 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

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.

Change from Baseline was calculated as the data collected at post-baseline visits minus the Baseline.
Baseline (Day 1) to Week 76
Part A and B: Change From Baseline in ECG Parameters: PR Interval, QRS Duration, QT Interval and Interval Corrected Using Fridericia's Formula (QTcF) Interval
기간: Baseline (Day 1) to Week 76

Triplicate 12-lead ECG was recorded with the participant in a supine position for at least 5 minutes. Changes in ECG parameters were defined according to protocol-specified criteria for change from baseline values as determined by the Investigator. 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.
Baseline (Day 1) to Week 76
Part A and B: Number of Participants With Treatment-emergent Adverse Events of Special Interest (AESI)
기간: Up to Week 80

An AE was defined as any untoward medical occurrence in any participant partaking 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. AESIs included injection site reactions, systemic injection reactions (e.g., hypersensitivity, systemic inflammatory response), and infection.
Up to Week 80
Part A and B: Mean Change From Baseline in the Manual Muscle Testing - 12 (MMT-12) Score at Week 76
기간: Baseline (Day 1) and up to Week 76

Manual Muscle Testing - 12 assessed the muscle strength across the muscle groups that included neck flexion and both right and left shoulder abduction, elbow flexion, elbow extension, wrist extension, wrist flexion, flexor pollicis longus, hip flexors, hip abduction, hip extension, knee extension, and ankle dorsiflexion. Scores were calculated by summing the outcomes, with the Investigator providing the score, on a scale of 0 (no contraction) to 5 (normal strength), which is then converted by a standard procedure to a Kendall score equivalent on a scale of 0 to 10. Individual scores are summed to generate a total score ranging from 0 to 60. A higher score reflects better muscle strength. 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.
Baseline (Day 1) and up to Week 76
Part A and B: Mean Change From Baseline in the Hand Grip Strength Score by Dynamometry at Week 76
기간: Baseline (Day 1) and up to Week 76

Grip strength was assessed using a handheld dynamometer which provided a precise measurement of the force that a muscle can exert and reflects muscle strength of the hand. Positive values indicated increased grip strength and negative values indicated decreased grip strength. 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.
Baseline (Day 1) and up to Week 76
Part A and B: Mean Change From Baseline in the Quadriceps Strength Score by Dynamometry at Week 76
기간: Baseline (Day 1) and up to Week 76

Quadriceps strength was measured using a dynamometer which provided the applied force of leg extension and reflects muscle strength of the dominant leg. Positive values indicated increased strength and negative values indicated decreased strength. 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.
Baseline (Day 1) and up to Week 76
Part A and B: Mean Change From Baseline in Modified Timed Up and Go Test (mTUG) at Week 76
기간: 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.
Baseline (Day 1) and up to Week 76
