-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Concentration-Time Curve From Zero to Infinity (AUC [0-infinity]) | AUC (0 - infinity) = Area under the serum concentration versus time curve (AUC) from time zero to infinite time, obtained from AUC (0 - t) plus AUC (t - infinity). Units are day*micrograms per millilitres = day*mcg/mL. | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Maximum Observed Serum Concentration (Cmax) | The Cmax is the maximum observed serum concentration of tralokinumab. | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Time to Maximum Concentration (Tmax) | Tmax is defined as actual sampling time to reach maximum observed tralokinumab concentration. | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Area Under the Concentration-Time Curve From Zero to Last Measurable Concentration (AUC [0-t]) | AUC [0-t] is defined as area under the serum concentration-time curve from zero to last observed tralokinumab concentration. | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Terminal Elimination Half-life (t1/2) | Terminal elimination half-life is the time measured for the serum concentration to decrease by one half. It is associated with the terminal slope of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z). | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Apparent Systemic Clearance (CL/F) After Subcutaneous Dose | Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after subcutaneous dose (apparent systemic clearance) is influenced by the fraction of the dose absorbed (bioavailability). | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 
| Apparent Terminal-Phase Volume of Distribution (Vz/F) | Volume of distribution was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired serum concentration of a drug. | Day 1 (pre-dose sample collected within 30 minutes prior to study drug administration), Days 2, 4, 6, 8, 10, 15, 22, 36, and 57 post-dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Local Injection-Site Pain and Injection-Site Pruritus | Local injection-site pain and pruritus intensity was rated on 0 to 100 millimeter (mm) visual analogue scale (VAS) at various time points, where 0 = no pain/ no pruritus; 100 = most severe pain/ most severe pruritus. Injection site pruritus intensity was assessed by the blinded assessor. Higher the score indicated higher intensity of pain and pruritus. Local injection site pain and pruritus was assessed at below time-points: 1 and 6 minute (min) during investigational product administration (IPA); immediately post IPA, 10, 20, 30, and 60 min, 2, 4, 8, 24 and 72 hour (h) post IPA. | During the injection until 72 hours post-injection for injection site-pain and immediately after administration of injection until 72 hours for injection-site pruritus | 
| Number of Participants Reporting Local Injection-Site Reactions | The signs and/or symptoms of local injection-site reactions including erythema, hematoma or bleeding, local warmth, swelling, and/or rash occurring within 72 hours post-injection were assessed and recorded by a blinded assessor. | 0, 10, 20, 30 and 60 minutes, 2, 4, 8, 24 and 72 hours post-injection | 
| Number of Participants Reporting Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs) | An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (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 and important medical event. Treatment-emergent were events between administration of study drug and up to Day 57 that were absent before treatment or that worsened relative to pre-treatment state. | From start of study drug administration up to Day 57 | 
| Number of Participants Reporting Treatment-emergent Adverse Events Related to Physical Examination | The treatment-emergent adverse events related to physical examination were reported as per investigator discretion. Treatment-emergent were the events between administration of study drug and up to Day 57 that were absent before treatment or that worsened relative to pre-treatment state. | Day 1 to Day 57 | 
| Number of Participants Reporting Treatment-emergent Adverse Events Related to Vital Signs | Vital signs included systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate and temperature. The treatment-emergent adverse events related to vital signs were reported as per investigator discretion. Treatment-emergent were the events between administration of study drug and up to Day 57 that were absent before treatment or that worsened relative to pre-treatment state. | Day 1 to Day 57 | 
| Number of Participants Reporting Treatment-emergent Adverse Events in Laboratory Parameters | Laboratory parameters included hematology, serum chemistry and urinalysis. The treatment-emergent adverse events in laboratory parameters were reported as per investigator discretion. Treatment-emergent were the events between administration of study drug and up to Day 57 that were absent before treatment or that worsened relative to pre-treatment state. | Day 1 to Day 57 | 
| Number of Participants Exhibiting Anti-Drug Antibodies for Tralokinumab at Any Visit | Immunogenicity assessment included determination of anti-drug antibodies to tralokinumab (CAT-354) antibodies in serum samples. | Pre-dose on Day 1 and Day 57 |
