Arm Label

MEDI9929, 140 mg, Cohort 1 (12 to 14 years)

MEDI9929, 140 mg, Cohort 2 (15 to 17 years)

Arm Description

On Day 1, one MEDI9929 subcutaneous injection of 70 mg was given into the anterior aspect of one thigh immediately followed by the second injection of 70 mg into the anterior aspect of the contralateral thigh to make the required dose of 140 mg in participants with 12 to 14 years of age.

Outcomes

Primary Outcome Measures

Area Under the Concentration-time Curve From Zero to Infinity (AUC [0-infinity])

The pharmacokinetic (PK) parameter AUC (0 to infinity) was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Area Under the Concentration-Time Curve From Zero to Last Observation (AUC [0-t])

The PK parameter AUC (0-t) was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Dose-normalized AUC (0-infinity) (AUC [0 Infinity]/D)

The AUC (0-infinity)/D is the area under concentration-time curve extrapolated to infinity postdose normalized by MEDI9929 dose. The PK parameter was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Maximum Observed Serum Concentration (Cmax)

The PK parameter Cmax was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Dose-normalized Cmax (Cmax/D)

The Cmax/D is the maximum observed concentration post dose normalized by MEDI9929 dose. The PK parameter was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Time to Reach Cmax (Tmax)

The Tmax is the time to maximum observed serum concentration of MEDI9929. The PK parameter was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Terminal Phase Elimination Half Life (t1/2,z)

The t½,z is the time measured for the serum drug concentration of MEDI9929 to decrease by one half. The PK parameter was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Apparent Clearance (CL/F)

The PK parameter CL/F was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Apparent Steady-state Volume of Distribution (Vss/F)

The PK parameter Vss/F was estimated based on the serum concentrations of MEDI9929. Serum concentrations of MEDI9929 were measured by enzyme-linked immunosorbent assay.

Secondary Outcome Measures

Number of Participants Reporting Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events

An adverse event (AE) is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A serious adverse event (SAE) is any AE resulting in any of the following outcomes such as death; initial or prolonged inpatient hospitalization; life-threatening; persistent or significant disability/incapacity; congenital anomaly or birth defect, or is an important medical event that may jeopardize the participant or may require medical intervention to prevent one of the outcomes listed above. A TEAE is defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug. The AEs were summarized using Medical Dictionary for Regulatory Activities version 19.0

Treatment-emergent Adverse Events Related to Vital Sign Parameters and Physical Findings

Vital signs (blood pressure, temperature, pulse, and respiratory rate) were performed throughout the study. The TEAEs related to vital signs in participants were reported.

Treatment-emergent Adverse Events Related to Laboratory Parameters

Laboratory evaluations of blood and urine samples were performed, including hematology (white blood cell count with differential, red blood cell count, hematocrit, hemoglobin and platelet count); serum chemistry: calcium, chloride, potassium, sodium, bicarbonate, aspartate transaminase, alanine transaminase, albumin, uric acid, creatinine, total bilirubin, glucose, alkaline phosphatase, blood urea nitrogen, total protein, and gamma glutamyl transferase; and urinalysis (nitrites, protein, glucose, ketones, urine drug screen, blood, and bilirubin). Number of participants with TEAEs related to laboratory evaluations were reported.

Treatment-emergent Adverse Events Related to Electrocardiogram Evaluations

Computerized triplicate 12-lead ECGs as well as Qualitative 12-lead ECGs were obtained during the study. ECG parameters included heart rate, PR, QRS, QT, and corrected QT (QTc) intervals. Number of participants with TEAEs related to ECG after the start of study drug were to be reported.

Number of Participants Positive for Anti-drug Antibodies and With Neutralizing Antibodies for MEDI9929 at Any Visit

Blood samples for immunogenicity assessment included the determination of anti-drug antibodies (ADA) for MEDI9929. The incidence rate of positive serum antibodies to MEDI9929 were presented.
