Study to Evaluate the AIO-001 in Healthy Participants

Open-Label, Single Dose, Parallel Group, Phase 1 Study in Healthy Volunteers Evaluating Safety, Tolerability, Pharmacokinetics, and Immunogenicity AIO-001 Administered by Injections

This goal of the open-label single dose study is to evaluate and compare the safety, tolerability, pharmacokinetic (PK), and immunogenicity of AIO-001 using two different formulations in 16 healthy volunteers.

This is an open-label single dose, parallel group, 24-week, Phase 1 study in 16 healthy participants.

The study is designed to evaluate and compare the safety, tolerability, PK, and immunogenicity of AIO-001 using two different formulations (Formulation A and Formulation B) in 16 healthy volunteers (8 receiving each formulation).

The study will include a screening visit from Day -28 to Day -2. Eligible participants will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 3. Participants will return to the clinical site for outpatient visits for study assessments and laboratory tests.
