A Bioequivalence Study of Amlitelimab Delivered by 2 Different Devices in Healthy Adult Participants
- Summary
- This is a single-center, open-label, randomized, single-dose, parallel, Phase 1, 4-arm study designed to determine the bioequivalence and investigate the safety and tolerability profiles of subcutaneous amlitelimab delivered by 2 different devices at 2 different total doses in healthy adult participants.

PK parameter: Cmax
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Maximum serum concentration observed.
Pharmacokinetic (PK) profile: AUC last
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Area under the serum concentration versus time curve calculated using the trapezoidal method from time zero to the real time.
Pharmacokinetic (PK) profile: AUC
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Area under the serum concentration versus time curve extrapolated to infinity.
PK parameter: Tmax
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Time to reach Cmax.
PK parameter: t1/2z
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Terminal half-life associated with the terminal slope (λz) determined
PK parameter: CL/F
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Apparent total body clearance after a single subcutaneous administration of a drug from the serum.
PK parameter: Vz/F
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Apparent volume of distribution during the terminal (λz) phase.
Pharmacokinetic (PK) profile: AUCext
Timeframe: From Day 1 up to End of study (approximately 24 weeks)
Percentage of extrapolated part of AUC.
Percentage of participants who experienced TEAEs including ISRs, TESAEs, and/or TEAESIs
Timeframe: Up to end of study (approximately 24 weeks)
TEAEs (Treatment-Emergent Adverse Events) including ISRs (local tolerability assessment), TESAEs (Treatment-Emergent Serious Adverse Events), and/or TEAESIs (Treatment Emergent Adverse Event of Special Interest).
Percentage of participants with potentially clinically significant abnormalities
Timeframe: Up to end of study (approximately 24 weeks)
Clinically significant abnormalities including Clinical laboratory evaluations, Vital signs, electrocardiogram (ECG).
Visual analog scale score for pain with subcutaneous administration
Timeframe: Day 1
VAS (visual analog scale) is used to evaluate pain at the treatment injection site. In a range between 0 to 10 where 10 is the worst pain.
Incidence of participants with ADA (antidrug antibody) against amlitelimab.
