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

Intervention/TreatmentCaveolin-1-Scaffolding-Protein-Derived Peptide (LTI-03) ...
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.

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 Willing and able to provide written informed consent 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 Any clinically significant illness and/or surgery within 28 days prior to dosing Febrile illness within 7 days prior to dosing Weight loss > 5 kg within 28 days prior to dosing Clinically significant 12-lead electrocardiogram (ECG) abnormalities or vital sign abnormalities (systolic blood pressure < 90 mmHg or > 140 mmHg, diastolic blood pressure < 50 mmHg or > 90 mmHg, or heart rate < 45 beats per minute [bpm] or > 100 bpm) 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 History of cancer with the exception of adequately treated basal cell or squamous cell carcinoma of the skin Hemoglobin < lower limit of normal (LLN) Abnormal liver function- alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2 times the upper limit of the normal range (ULN) - total bilirubin > 1.5 times ULN Abnormal renal function: estimated glomerular filtration rate (eGFR) (modification of diet and renal disease [MDRD]) < 55 mL/min/1.73 m2 Pulmonary function outside the normal range, including forced expiratory volume 1 (FEV1), forced vital capacity (FVC) each < 80% of predicted or FEV1/FVC ratio of ≤ 0.7 at Screening Inability to use study inhaler device appropriately. Positive test results for human immunodeficiency virus (HIV) HIV-1/HIV-2 antibodies, hepatitis B surface antigen (HBsAG) or hepatitis C virus antibody (HCV-AB) Concurrent Intake of Other Substances 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 History of drug abuse or misuse within 5 years prior to dosing or a positive urine drug test at Screening or Day -1 Inability or unwillingness to abstain from alcohol or any drug of abuse for 48 hours prior to the first dose until completion of the Day 8 visit for the SAD and Day 21 visit for the MAD Exposure to any live vaccines within 28 days prior to dosing Treatment with an investigational product within 30 days or 5 half-lives (whichever is longer) prior to dosing Use of prescription or non-prescription medications and dietary supplements within 14 days or 5 half-lives (whichever is longer) prior to the first dose of study medication.
