Study Details

Study Description

Brief Summary

This study will evaluate the safety, tolerability and pharmacokinetics of USB005 (aclerastide) Ophthalmic Solution.

Condition or Disease	Intervention/Treatment	Phase
Healthy Volunteers	Drug: USB005 (aclerastide) Ophthalmic Solution Drug: USB005 Ophthalmic Solution Placebo	Phase 1

Detailed Description

This is a Phase 1, single-center, randomized, double-masked, placebo-controlled, multiple ascending dose study in healthy volunteers. Thirty-two male and female volunteer subjects, between the ages of 18 and 64 years of age, will be enrolled. Subjects will be enrolled in four dose-escalating cohorts of eight subjects and randomized to USB005 or placebo in a ratio of 3:1. Cohorts will be enrolled sequentially starting at the lowest concentration. The four cohorts will be identified as: Cohort 1(0.03% USB005 or placebo), Cohort 2 (0.1% USB005 or placebo), Cohort 3 (0.3% USB005 or placebo), and Cohort 4 (0.45% USB005 or placebo). Volunteers in the four cohorts will self-administer a single drop of USB005 or placebo into the study eye, three times a day for 28 days. The study eye in which the drug is applied to will be determined based on screening assessments. Subjects will be followed for 8 days after the last USB005 or placebo administration.

The safety and tolerability of USB005 will be demonstrated by local toxicity, adverse events, laboratory assessments, vital signs, and a comprehensive eye exam. Plasma samples will be taken at various time points throughout the study to characterize the pharmacokinetics of USB005. Dropouts will be replaced after consultation with the Sponsor.
