ListOutcomeTime frameDescription
PrimaryNumber of Participants With Treatment Emergent Adverse Events (TEAEs)Up to End of Study (up to Week 25)
TEAEs were defined as adverse events (AEs) with an onset following administration of the first dose of study drug. An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with study drug. Worsening of a pre-existing medical condition, (that is, diabetes, migraine headaches, gout) should have been considered an AE if there was either an increase in severity, frequency, or duration of the condition or an association with significantly worse outcomes. Classification of AEs was to be done by the Investigator according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.03. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
PrimaryNumber of Participants With Positive Anti-Drug Antibodies (ADA)Baseline up to Week 14Titers through Week 14 are summarized. For Cohorts 1 and 2, samples that screened positive but did not confirm on confirmatory assay were not titered.
PrimaryNumber of Participants With a Positive or Equivocal Jo-1 Antibody (Ab) Test ResultBaseline up to Week 14
Criterion for a positive Jo-1 Ab test result: \>10.0 units/milliliter (U/mL), a cut-point associated with anti-synthetase syndrome. Criterion for an equivocal Jo-1 Ab test result: 7.0 to 10.0 U/mL. Participants were required to have a negative Jo-1 Ab test result (defined as \<7 U/mL) for inclusion in the study as well as to continue dosing with study drug during the study.
PrimaryNumber of Participants With a Clinically Significant Laboratory AbnormalityBaseline up to Week 14
Laboratory parameters included hematology (hematocrit, hemoglobin, platelet count, red blood cell count, white blood cell count, neutrophils, lymphocytes, monocytes, eosinophils, basophils); serum chemistries (blood urea nitrogen, creatinine, total bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase (GGT), alkaline phosphatase, sodium, total protein, bicarbonate, potassium, calcium, chloride, magnesium, inorganic phosphate, creatine phosphokinase \[will be fractionated if elevated\], lactic dehydrogenase, erythrocyte sedimentation rate, C-reactive protein, troponin, myoglobin, insulin-like growth factor 1, cholesterol \[non-fasting\]); Urinalysis (Color, pH, specific gravity, protein, glucose, ketones, blood). Clinically significant laboratory abnormalities were based upon Investigator's discretion. A summary of all Serious AEs and Other AEs (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
PrimaryNumber of Participants With a Physical Examination AbnormalityUp to End of Study (up to Week 25)
Body systems that were evaluated during the physical examination included general appearance, head, eyes, ears, nose, throat (HEENT), cardiovascular system, respiratory system, chest (breasts), gastrointestinal system (abdomen), lymphatic system, musculoskeletal system, skin, psychiatric, and neurologic. Neurologic examination included assessment of mental status, memory, cranial nerves, motor function, and reflexes, and sensory testing. The body systems with at least 1 physical abnormality is presented. One participant could be represented in more than 1 body system category. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
PrimaryNumber of Participants With a Vital Sign-Related Event Resulting in a TEAEUp to End of Study (Up to Week 25)
The vital sign parameters that were evaluated included heart rate, systolic and diastolic blood pressure, and respiration rate as well as temperature. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
PrimaryNumber of Participants With a Pulmonary Function Event Resulting in a TEAEUp to End of Study (Up to Week 25)
Pulmonary function testing included measurements of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1). A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
SecondaryPercent Change From Baseline in Manual Muscle Testing (MMT) Score at Week 6 and Week 14Baseline, Week 6 and Week 14
MMT was graded on a scale from 0 (no movement) to 10 (normal movement). Each side of the body and the position in which each muscle was tested were recorded for each participant. The total MMT score were calculated by averaging a converted MMT scores across all tested muscle groups. Decreased motor function was indicated by decreased individual muscle or composite MMT score.
SecondaryChange From Baseline in Individualized Neuromuscular Quality of Life (INQoL) - Overall QoL at Week 6 and Week 14Baseline, Week 6 and Week 14
The INQoL is a validated muscle disease-specific measure of quality of life. The self-administered questionnaire consisted of 45 questions with 4 domains measuring the impact of common muscle disease symptoms (weakness, locking \[or myotonia\], pain, and fatigue); 5 domains measuring the influence of the muscle disease on particular areas of life (activities, independence, relationships, emotions, and body image); and the last domain focused on the positive and negative effects of treatment and was divided into 2 scores. All responses were given in a 7-point Likert scale, with improved QoL indicated by decreased scores. Overall QoL score was calculated from preselected 5 domains (activities, independence, relationships, emotions, and body image) by adding the scores from each domain. In summary, INQoL yielded 11 scores and 1 QoL score. The Overall scoring used a scale of 0-100, with improved QoL indicated by decreased scores.
