Unable to refrain from or anticipates the use of any drug, including prescription and non-prescription medications, herbal remedies, or vitamin supplements within 14 days prior to the first dosing and throughout the study. Medication listed as part of acceptable birth control methods will be allowed.

After randomization/dosing, a nonsteroidal anti-inflammatory drug may be administered at the discretion of the investigator. Hormone replacement therapy will also be allowed if the participant has been on the same stable dose for the immediate 3 months prior to first study drug administration.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Participant will receive single dose of lanadelumab matching placebo (normal saline) IV infusion on Day 1 followed by second dose on Day 4.
Lanadelumab 300 mg	Lanadelumab	Participants will receive single dose of lanadelumab 300 mg intravenous (IV) infusion on Day 1 followed by second dose on Day 4.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Clinically Significant Change From Baseline in 12-lead Electrocardiogram (ECG) Findings	From the first dose of study treatment up to the end of study (Day 112)	12-lead ECG recordings included rhythm, heart rate (as measured by RR interval), PR interval, QRS duration, and QT interval. Any changes in ECG parameters that were deemed clinically significant were judged by the investigator. The number of participants with clinically significant changes from baseline in 12-lead ECG findings were reported.
AUC0-last: Area Under the Plasma Concentration-time Curve From Time Zero to the Last Quantifiable Concentration for Lanadelumab	Pre-dose (Day 1) up to 2664 hours post-dose	AUC0-last for lanadelumab was reported.
Terminal Half-Life (T1/2) of Lanadelumab in Plasma	Pre-dose (Day 1) up to 2664 hours post-dose	T1/2 is defined as the time required for the concentration of the drug to reach half of its original value. T1/2 for lanadelumab was reported.
Tmax1: Minimum Observed Time to Reach the First Cmax1 for Lanadelumab	Pre-dose (Day 1) up to 2664 hours post-dose	Tmax1 following the first IV dose for lanadelumab was reported.

Number of Participants With Clinically Significant Change From Baseline in Laboratory Parameters	From the first dose of study treatment up to the end of study (Day 112)	Clinical laboratory assessment included hematology, clinical chemistry, coagulation, and urinalysis.

Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)	From the first dose of study treatment up to the end of study (Day 112)	An adverse event (AE) was defined as any untoward medical occurrence in a clinical investigation participant who has signed informed consent to participate in a study that did not necessarily have a causal relationship with the treatment. TEAEs were events that occurred on or after the date and time of administration of the first dose of study medication. TEAEs included both serious TEAEs and non-serious TEAEs. Number of participants with TEAEs were reported.
Number of Participants With Clinically Significant Change From Baseline in Vital Signs	From the first dose of study treatment up to the end of study (Day 112)	Vital signs included blood pressure (systolic and diastolic), heart rate, and body temperature (oral). Any changes in vital signs that were deemed clinically significant were judged by the investigator. The number of participants with clinically significant change from baseline in vital signs were reported.
Cmax2: Maximum Observed Plasma Concentration Following the Second IV Dose for Lanadelumab	Pre-dose (Day 4) up to 2592 hours post-dose	Cmax2 following the second IV dose for lanadelumab was reported.
Clearance (CL) of Lanadelumab in Plasma	Pre-dose (Day 1) up to 2664 hours post-dose	Clearance is defined as a quantitative measure of the rate at which a drug substance is removed from the body. CL for lanadelumab was reported.
Cmax1: Maximum Observed Plasma Concentration Following the First IV Dose for Lanadelumab	Pre-dose (Day 1) up to 2664 hours post-dose	Cmax1 following the first IV dose for lanadelumab was reported.
Vss: Volume of Distribution at Steady State in Plasma for Lanadelumab	Pre-dose (Day 1) up to 2664 hours post-dose	Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Vss for lanadelumab was reported.
First Order Elimination Rate Constant Associated With the Terminal (Log-linear) Portion of the Curve (Lambda z) of Lanadelumab	Pre-dose (Day 1) up to 2664 hours post-dose	Lambda z of Lanadelumab was reported.
