Study Endpoints
Primary Endpoints
The Incidence of Treatment Emergent Adverse Events From Baseline
From day 1 through the end of study follow-up, an average of 15 months.

Safety and tolerability will be evaluated by incidence rate of treatment emergent adverse events from baseline.

Clinically Significant Changes From Baseline Chemistry Laboratory Tests
From day 1 through the end of study follow up, an average of 15 months.

Number of participants with clinically significant changes in clinical laboratory tests

Clinically Significant Changes From Baseline Hematology Laboratory Tests
From day 1 through the end of study follow up, an average of 15 months.

Number of participants with clinically significant changes in clinical laboratory tests.

Clinically Significant Changes From Baseline Vital Signs
From day 1 through the end of study follow up, an average of 15 months.

Number of participants with clinically significant changes in vital signs.

Clinically Significant Changes From Baseline Electrocardiograms (ECGs)
From day 1 through the end of study follow up, an average of 15 months.

Safety will be assessed by evaluating clinically significant changes from Baseline ECGs change in mean ventricular rate \[beats/min\].

Clinically Significant Changes From Baseline Electrocardiograms (ECGs) Measures
From day 1 through the end of study follow up, an average of 15 months.

Safety will be assessed by evaluating clinically significant changes from Baseline ECGs change in pulse rate \[msec\].

Clinically Significant Changes From Baseline QTC Interval
From day 1 through the end of study follow up, an average of 15 months.

Safety will be assessed by evaluating clinically significant changes from Baseline ECGs change in QTC interval

Clinically Significant Changes From Baseline QRS Interval
From day 1 through the end of study follow up, an average of 15 months.

Safety will be assessed by evaluating clinically significant changes from Baseline ECGs change in QRS interval.

Secondary Endpoints
Concentration of Lotilaner in Whole Blood
From dose through study completion, an average of 15 months.
Terminal Elimination Half Life (t½) of Lotilaner
At protocol specified timepoints through end study treatment phase, an average of 28 weeks.
Area Under the Concentration Time Curve (AUC) of Lotilaner
At protocol specified timepoints through end of pharmacokinetic sampling, an average of 15 months.
