Study Endpoints

Primary Endpoints

Maximum Observed Serum Concentration (Cmax) of Efavaleukin Alfa
Day 1: Pre-dose, 6, 12, & 16 hours post-dose, and days 2 (24 hours post-dose), 3, 4, 5, 6, 8, 11, 15, 22, 29 and 43

Blood samples were collected to determine PK parameters.

Time of the Maximum Observed Serum Concentration (Tmax) of Efavaleukin Alfa
Day 1: Pre-dose, 6, 12, & 16 hours post-dose, and days 2 (24 hours post-dose), 3, 4, 5, 6, 8, 11, 15, 22, 29 and 43

Blood samples were collected to determine PK parameters.

Area Under the Serum Concentration Time Curve From Time Zero to Time of Last Quantifiable Concentration (AUClast) of Efavaleukin Alfa
Day 1: Pre-dose, 6, 12, & 16 hours post-dose, and days 2 (24 hours post-dose), 3, 4, 5, 6, 8, 11, 15, 22, 29 and 43

Blood samples were collected to determine PK parameters.

Area Under the Serum Concentration Time Curve From Time Zero to Infinity (AUCinf) of Efavaleukin Alfa
Day 1: Pre-dose, 6, 12, & 16 hours post-dose, and days 2 (24 hours post-dose), 3, 4, 5, 6, 8, 11, 15, 22, 29 and 43

Blood samples were collected to determine PK parameters.

Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE)
Day 1 up to end of study, maximum of 18 weeks (12-week double-blind treatment, 6-week safety follow-up)

A TEAE was defined as any adverse event (AE) starting on or after the first dose of investigational product through to the safety follow-up visit. Any clinically significant changes in physical examinations, vital signs, and clinical laboratory test results were recorded as AEs.
