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.

Criteria

Inclusion Criteria:

Non-smoker (no use of tobacco products within 6 months prior to dosing) with a negative urine cotinine test at Screening or Day -1
Age of 18-55 years (inclusive)
Body mass index (BMI) of 18 - 30.5 kg/m2 (inclusive)
Body weight > 50 kg

Exclusion Criteria:

History of asthma
Presence 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 or designee
Pulmonary infiltrate or pneumonia within 6 months prior to dosing or acute infection within 14 days prior to dosing
History of significant allergy or anaphylaxis
Any clinically significant hematologic, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic or allergic disease (excluding hay fever), as determined by the Investigator or designee
Any current clinically relevant abnormalities identified by a detailed medical history, complete physical examination including blood pressure and heart rate measurement, and clinical laboratory tests (hematology, coagulation, urinalysis, clinical chemistries) at Screening or Day -1, as determined by the Investigator or designee

History of, or existing severe, acute, chronic, and/or psychiatric medical condition(s), laboratory abnormality, or other medical concerns that may increase the risk associated with study participation or IMP administration which, in the judgment of the Investigator, would make the subject inappropriate for entry into the study
