Clinical Trial Summary

This is a phase 1, open-label, randomized pharmacokinetic and safety study in healthy adult subjects, who will undergo bronchoscopy and bronchoalveolar lavage (BAL) after receiving seven (7) doses of 1.0 mg/kg IV TP-434.

Description:

This is a phase 1, open-label, randomized pharmacokinetic and safety study in healthy adult subjects, who will undergo bronchoscopy and bronchoalveolar lavage (BAL) after receiving seven (7) doses of 1.0 mg/kg IV TP-434. Dosing will be twice daily (q12h) for three consecutive days beginning on day one (1) and a morning dose on day four (4).

Approximately 20 subjects will be enrolled into the study at one (1) investigational site. The population for this study is healthy male and female subjects 18 to 65 years of age.

This study includes a Screening Period of up to 30 days, a 4 day, open-label Treatment Period, and a two week Follow-up Period. There will be one 6 day/5 night inpatient stay (Days -1 to 5) during the Treatment Period and one outpatient visit at the end of the Follow-up Period. Excluding the Screening Period, the total duration of confinement (in the Clinical Research Center) will be approximately six (6) days and the total study duration, not including screening, will be approximately three (3) weeks.

Participants will be admitted to the Clinical Research Center on Day -1. Participants will receive four (4) days of intravenous TP-434 1.0 mg/kg of body weight twice daily (q12h) for three consecutive days and a morning dose on day four (4) (for a total of 7 doses) starting on Day 1. Blood and urine samples, ECGs, and vital signs will be collected for safety analysis at specified time points.

Pharmacokinetic blood sampling will occur on Day 4before and after the Day 4 dose of TP-434 at specified time points.

Participants will be randomized to a single BAL procedure time point. Bronchoscopy and BAL will be performed at the following time points after dosing of TP-434 on Day 4: two (2), four (4), six (6), and 12 hours after start of infusion. Bronchoscopy and BAL will be conducted for up to five (5) different participants at each time point. Each subject will undergo bronchoscopy and BAL only once.

Type	Measure	Description	Time frame	Safety issue
Primary	To determine the steady-state plasma pharmacokinetics and disposition of TP-434 into the epithelial lining fluid (ELF) and alveolar macrophages (AM) of healthy adult subjects after intravenous (IV) administration.		End of Therapy (Day 4)
Secondary	To determine the safety and tolerability of TP-434 in healthy adult subjects based primarily on the incidence, intensity and type of adverse events (AEs), clinical laboratory assessments, physical examinations, vital signs, and 12-lead ECGs.		Screening Visit through Day 20
