Study to Evaluate Safety and Activity of Inhaled TRL1068 in Healthy Volunteers

Официальное название

A Phase 1, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Pharmacokinetics of Inhaled TRL1068 in Healthy Volunteers

Обзор

This study in healthy volunteers will provide a basis for evaluation of inhaled TRL1068 as a first in human study, specifically, important safety, tolerability, and pharmacokinetic data.

Подробное описание

This is a Phase 1, double-blind study to assess the safety and PK of inhaled TRL1068. Healthy subjects aged 18-65, inclusive, will be screened. Subjects who meet all inclusion and no exclusion criteria will be enrolled into the study, assigned to a dose group (DG), and randomized to receive IP.

The single dose (SD) study (Study Part A) will enroll one dose group (DG) of 7 healthy participants (5 active and 2 placebo), with each participant receiving a single inhaled dose of TRL1068 or matching placebo \[IP\]. This DG will include a sentinel group of two participants (1 active and 1 placebo) who will be dosed at least 24 hours before the remaining five participants (4 active and 1 placebo). The remaining participants in a DG will only be dosed if no clinically significant safety or tolerability concerns are observed in the sentinel group, following review of the blinded safety data from the first two subjects in the DG by the PI and Sponsor. All participants in DG1 will be admitted to a Phase 1 research unit prior to the inhalation of IP on Day 1 and domiciled for 24 hours for observation.

The multiple dose (MD) study (Study Part B) will enroll one DG of 7 healthy participants (5 active and 2 placebo). Participants will receive inhaled doses of TRL1068 or matching placebo every other day for 7 days (on Days 1, 3, 5, and 7).

DGs will be enrolled sequentially with a safety review completed between DGs. A Study Monitoring Committee (SMC) will review all available safety data 48 hours after the last subject in a DG has completed the last dose prior to making a recommendation regarding escalation to the next higher DG.

Вмешательства

• Препарат TRL1068, a human monoclonal antibody
  The IP will be in a solution for inhalation at a nominal concentration of 20 mg/mL. The IP will be reconstituted with a formulation buffer to 10 mg/mL/PS20 0.055% and dosed at a fixed dose of 60 mg per dose (volume of 6 mL) to full completion. Placebo will be normal saline. This study will use a marketed nebulizer device, the Aerogen Solo™, which is designed to generate an aerosol to achieve effective levels of TRL1068 in distal airways.
