An Open-label Rollover Study of ARRY-371797 in Patients With Symptomatic Genetic Dilated Cardiomyopathy Due to a Lamin A/C Gene Mutation

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

时间窗: Baseline up to 30 days after last dose of study drug (i.e., maximum up to 282 weeks)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs were events between baseline up to 30 days after last dose of study drug (i.e., maximum up to 282 weeks) that were absent before treatment or that worsened relative to pre-treatment state. AEs included both serious and non-serious adverse events.

Number of Participants With Change From Baseline Value in Clinical Laboratory Hematology Test Results to Worst Value

时间窗: Baseline, Post-Baseline (anytime from first dose of study drug to maximum duration of up to 282 weeks)

In this outcome measure, number of participants with baseline laboratory hematology values as per National Cancer Institute Common Terminology Criteria (NCI-CTC) grade (Grade 0= within normal limits, Grade 1=Mild, Grade 2=Moderate, Grade 3= Severe, Grade 4= Life-threatening) and corresponding changes/shift to the worst CTC grades post baseline were presented. Shift data have been reported for hematology parameters: hemoglobin (g/L), platelets (10\^9/L), leukocytes (10\^9/L), neutrophils (10\^9/L), lymphocytes (10\^9/L) and eosinophils (10\^9/L). Baseline was defined as last non-missing value before the initial administration of study treatment in parent study and worst post-baseline value defined as worst value between first dose of study drug up to the maximum of 282 weeks. Only those categories in which at least 1 participant had data were reported.

Number of Participants With Change From Baseline Value in Clinical Laboratory Chemistry Test Results to Worst Value

时间窗: Baseline, Post-Baseline (anytime from first dose of study drug to maximum duration of up to 282 weeks)

In this outcome measure, number of participants with baseline laboratory chemistry values as per NCI-CTC grade (Grade 0= within normal limits, Grade 1=Mild, Grade 2=Moderate, Grade 3= Severe, Grade 4= Life-threatening) and corresponding changes/shift to the worst CTC grades post baseline were presented. Shift data have been reported for laboratory parameters: alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, international unit per liter (IU/L), albumin, bilirubin, urea nitrogen, calcium, creatinine, glucose, magnesium, protein and phosphate grams per deciliter (g/dL), potassium and sodium, millimol per liter (mmol/L). Baseline was defined as last non-missing value before the initial administration of study treatment in parent study and worst post-baseline value defined as worst value between first dose of study drug up to the maximum of 282 weeks. Only those categories in which at least 1 participant had data were reported.

Number of Participants With Abnormal Physical Examination Findings

时间窗: Baseline up to 30 days after last dose of study drug (i.e., maximum up to 282 weeks)

Physical examination included the assessment of skin, head, ears, eyes, nose, throat, cardiovascular system, abdomen and lungs. Abnormality in physical examination were based on investigator's discretion.

Number of Participants With Abnormalities in Vital Signs

时间窗: Baseline up to 30 days after last dose of study drug (i.e., maximum up to 282 weeks)

Following vital signs parameters were analyzed using prespecified range of results for signs of clinical significance: systolic blood pressure in millimeters of mercury (mmHg): \<90 mmHg and ≥160 mmHg, diastolic blood pressure: \<60 mmHg and ≥100 mmHg, heart rate in beats per minute (bpm): \<40bpm and \>120 bpm, temperature in degree Celsius (C): \<36.1 and \> 37.2 degree C.

Number of Participants With Abnormal 12-lead Electrocardiogram (ECG) Findings

时间窗: Baseline up to 30 days after last dose of study drug (i.e., maximum up to 282 weeks)

Following ECG parameters were analyzed using prespecified range of results for signs of clinical significance: heart rate: \<40bpm and \>120 bpm; QT/QTcF (QT interval corrected using Fridericia's formula) criteria: QT interval \>500 ms; QTcF interval \>450 ms; or change from baseline in QTcF \>30 ms.
