Safety, Tolerability and Pharmacokinetic Study of LTI-03 in Healthy Adult Subjects

A Randomized, Double-Blind, Placebo-Controlled, Ph 1a, First-in-Man, Single Ascending Dose & Multiple Ascending Dose Safety, Tolerability and PK Study of a Caveolin-1-Scaffolding-Protein-Derived Peptide (LTI-03) in Healthy Adult Subjects

The current study will investigate the initial safety, tolerability, and PK profile of inhaled LTI-03 in healthy volunteers. In order to minimize exposure, the study will first test single ascending doses (SAD) of LTI-03 followed by multiple ascending dose (MAD) cohorts.

Findings from this study will direct the clinical development of LTI-03 for the treatment of IPF

The study subject population will include normal healthy male and female volunteers between 18 and 55 years of age (inclusive).

Consistent with other trials involving inhaled medication, subjects must have normal pulmonary function at Screening and will be excluded if they have a history of active or recurring allergies, asthma, chronic obstructive pulmonary disease (COPD), chronic sinus drainage, chronic or acute cough or other respiratory condition deemed exclusionary by the Investigator. History of liver dysfunction or elevated bilirubin, alanine aminotransferase (ALT) or aspartate aminotransferase (AST) values at Screening will also be grounds for exclusion.

19. History of alcohol abuse within one year prior to Screening or regular use of alcohol of ≥ 14 units of alcohol per week for females and ≥ 21 units of alcohol for males (1 unit = 150 mL wine, 360 mL beer or 45 mL of 40% alcohol) within 6 months prior to dosing or a positive urine alcohol test at Screening or Day -1
