Orthostatic vital sign results with a decrease in systolic greater than (>) 20 mmHg or decrease in diastolic > 10 mmHg and increase in pulse of > 20 beats per minute. QTcF interval is > 450 milliseconds (msec) (males) or > 470 msec (females) or ECG findings are deemed abnormal with clinical significance at screening per the investigator. Estimated creatinine clearance less than (<) 80 milliliters per minute (mL/min) at screening. 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. Thyroid hormone replacement medication may be permitted if the participant has been on the same stable dose for the immediate 3 months prior to first study drug administration. 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.

Participation in another clinical study within 30 days or 5 half-lives prior to the first dosing. The 30-day window or 5 half-lives will be derived from the date of the last blood collection or dosing, whichever is later, in the previous study to Day 1 of the current study

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) | 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. | From the first dose of study treatment up to the end of study (Day 112) | 
| Number of Participants With Clinically Significant Change From Baseline in Laboratory Parameters | Clinical laboratory assessment included hematology, clinical chemistry, coagulation, and urinalysis. Any changes in clinical laboratory results that were deemed clinically significant were judged by the investigator. The number of participants with clinically significant change from baseline in laboratory values were reported. | From the first dose of study treatment up to the end of study (Day 112) | 
| Number of Participants With Clinically Significant Change From Baseline in Vital Signs | 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. | From the first dose of study treatment up to the end of study (Day 112) | 
| Number of Participants With Clinically Significant Change From Baseline in 12-lead Electrocardiogram (ECG) Findings | 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. | From the first dose of study treatment up to the end of study (Day 112) | 
| AUC0-last: Area Under the Plasma Concentration-time Curve From Time Zero to the Last Quantifiable Concentration for Lanadelumab | AUC0-last for lanadelumab was reported. | Pre-dose (Day 1) up to 2664 hours post-dose |

| Terminal Half-Life (T1/2) of Lanadelumab in Plasma | 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. | Pre-dose (Day 1) up to 2664 hours post-dose | 
| Clearance (CL) of Lanadelumab in Plasma | 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. | Pre-dose (Day 1) up to 2664 hours post-dose | 
| Vss: Volume of Distribution at Steady State in Plasma for Lanadelumab | 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.
