Pharmacokinetic Study to Compare Itepekimab Exposure When Administered With an Autoinjector Versus Prefilled Syringe

A Phase 1, Single-center, Open-label, Randomized, Parallel Group, Single-dose Study to Compare the Pharmacokinetics of Subcutaneous Itepekimab Administered With an Autoinjector Versus Prefilled Syringe in Healthy Participants

This Phase 1, single-center study will be conducted in an open-label, randomized, parallel design. Healthy male and female participants aged 18 to 65 years will receive a single dose of itepekimab subcutaneous (SC) administered by either a prefilled syringe (PFS) or an autoinjector (AI). Itepekimab will be administered by a trained healthcare professional (HCP).

Female and male participants will have a body weight between 50.0 and 100.0 kg and body mass index (BMI) >18.5 and ≤30 kg/m2.

Participants who satisfy the inclusion criteria will be randomized to one of the 2 study intervention groups:

• Itepekimab administered via AI (test)
• Itepekimab administered via PFS (reference) The randomization will be stratified by weight category (<70 kg, ≥70 to <80 kg and ≥80 kg) and injection site (abdomen, thigh, and arm).

Study duration for each participant is up to approximately 162 days, including:

• Screening period: up to 21 days
• Institutionalization: 2 days including 1 treatment day (Day 1)
• Follow-up period: 140 days (±5 days)
• End of study (EOS): Day 141 (± 5 days)

Inclusion Criteria:

• Having given written informed consent prior to undertaking any study-related procedure.

Exclusion Criteria:

Participants are excluded from the study if any of the following criteria apply:

• Any participant who, in the judgment of the Investigator, is likely to be noncompliant during the study, or unable to cooperate because of a language problem or poor mental development.
