Treatment and study plan

CAT-354 150 mg (intravenous)

Biological

A single dose of CAT-354 150 milligram (mg) intravenous infusion over 30 minutes on Day 0.

Other names: Tralokinumab

CAT-354 150 mg (subcutaneous)

Biological

A single dose of CAT-354 150 mg injection subcutaneously on Day 0.

Other names: Tralokinumab

CAT-354 300 mg (subcutaneous)

Biological

A single dose of CAT-354 300 mg injection subcutaneously on Day 0.

Other names: Tralokinumab

Primary outcomes

  1. Absolute Bioavailability of CAT-354 After Subcutaneous Dose

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    Bioavailability (F) is a measurement of the rate and extent to which a drug reaches the systemic circulation. Absolute bioavailability of the subcutaneous doses was assessed by the geometric least-square means ratios of subcutaneous to intravenous dose-normalized area under the serum concentration-time curve from time zero to infinity (AUC [0 - infinity]/Dose). AUC (0 - infinity) = Area under the serum concentration versus time curve (AUC) from time zero (predose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity).

Secondary outcomes

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

    Time frame: Day 0 to 56

    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. Treatment-emergent are events between administration of study drug and up to Day 56 that were absent before treatment or that worsened relative to pre-treatment state.

  2. Number of Participants Exhibiting Anti-Drug Antibodies for CAT-354 at Any Visit

    Time frame: Day 0 and Day 56

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

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    AUC (0 - infinity) = Area under the serum concentration versus time curve (AUC) from time zero (predose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity).

  4. Area Under the Serum Concentration Time Curve From Time Zero to Last Measurable Concentration (AUC[0 - 56])

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

  5. Dose Normalized Area Under the Concentration-time Curve From Zero to Infinity ([AUC {0 - Infinity}]/Dose)

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    AUC (0 - infinity) = Area under the serum concentration versus time curve (AUC) from time zero (predose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity). (AUC [0 - infinity]) was normalized by CAT-354 dose.

  6. Maximum Observed Serum Concentration (Cmax)

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

  7. Dose Normalized Maximum Observed Concentration (Cmax/Dose)

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

  8. Time to Reach Maximum Observed Serum Concentration (Tmax)

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

  9. Terminal Phase Elimination Half Life (t1/2)

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion/post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    Terminal phase elimination half-life is the time measured for the serum concentration to decrease by one half.

  10. Apparent Systemic Clearance (CL/F) After Subcutaneous Dose

    Time frame: Predose, 30 minutes, at 1, 3, 8 and 24 hours post-injection on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    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).

  11. Apparent Systemic Clearance (CL/F) After Intravenous Dose

    Time frame: Predose, end of infusion, 30 minutes, 1, 3, 8 and 24 hours post-end of infusion on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.

  12. Volume of Distribution at Steady State (Vss) After Intravenous Infusion

    Time frame: Predose, end of infusion, 30 minutes, at 1, 3, 8 and 24 hours post-end of infusion on Day 0; Day 3, 5, 7, 9, 14, 21, 28, 35, 42 and 56

    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. Volume of distribution at steady state (Vss) after intravenous dosing was estimated by the formula Vss=MRT(Infinity)*CL, where MRT(Infinity)= AUCM(Infinity)/AUC(0 - infinity) where MRT(Infinity) = mean residence time at infinity, CL= clearance, AUCM[Infinity] = area under the moment curve, and AUC (0 - infinity) = area under the serum concentration versus time curve from time zero (predose) to extrapolated infinite time (0 - infinity).
