Official title
A Randomized, Double-Blind, Placebo-Controlled, First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of Single Doses of LCA-0061 in Atopic Healthy Participants and Multiple Doses of LCA-0061 in Participants With Peanut Allergy
Overview
This is a Phase 1combined single ascending dose (SAD)/multiple ascending dose (MAD) randomized, double-blind, placebo-controlled trial to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of single and multiple ascending subcutaneous doses of LCA-0061in participants with atopic conditions (SAD) and participants with peanut allergy (MAD).
Interventions
- Drug LCA-0061
LCA-0061 is an antibody-based therapeutic designed to selectively bind and rapidly clear immunoglobulin E (IgE) via targeted degradation - Drug Placebo
Placebo
Primary outcome measures
- Occurrence of treatment-emergent adverse events (TEAEs) [Time frame: Part A (SAD) Cohorts: Day 1 up to Day 36 - Part B (MAD) Cohorts: Day 1 up to Day 93]
- Occurrence of TEAEs leading to discontinuation [Time frame: Part A (SAD) Cohorts: Day 1 up to Day 36 - Part B (MAD) Cohorts: Day 1 up to Day 93]
- Occurrence of TEAE by severity [Time frame: Part A (SAD) Cohorts: Day 1 up to Day 36 - Part B (MAD) Cohorts: Day 1 up to Day 93]
- Occurrence of Clinically significant laboratory values, electrocardiograms (ECGs), and vital signs [Time frame: Part A (SAD) Cohorts: Day 1 up to Day 36 - Part B (MAD) Cohorts: Day 1 up to Day 93]
Secondary outcome measures (9)

- Single-dose pharmacokinetic parameter- t½ [Time frame: Part A (SAD) Cohorts: Pre-dose through Day 36]
- Multiple-dose pharmacokinetic parameter--Cmax [Time frame: Part B (MAD) Cohorts: Pre-dose through Day 93]
- Multiple-dose pharmacokinetic parameter-Tmax [Time frame: Part B (MAD) Cohorts: Pre-dose through Day 93]
- Multiple-dose pharmacokinetic parameter-AUC0-∞ [Time frame: Part B (MAD) Cohorts: Pre-dose through Day 93]
- Multiple-dose pharmacokinetic parameter-t½ [Time frame: Part B (MAD) Cohorts: Pre-dose through Day 93]
- Accumulation Ratio [Time frame: Part B (MAD) Cohorts: Pre-dose through Day 93]
