A Six Week Pharmacokinetic Study of TP-03 in Healthy Subjects
- Conditions
- Healthy
- Interventions
- Drug: TP-03 (Lotilaner Ophthalmic Solution), 0.25%
- Registration Number
- NCT05138861
- Lead Sponsor
- Tarsus Pharmaceuticals, Inc.
- Brief Summary
Pharmacokinetic Study to Evaluate the Whole Blood Pharmacokinetics of TP-03 Following Six Week Topical Ocular Administration.
- Detailed Description
This is a single-center, open-label, single-arm study. A single drop of the ophthalmic solution will be instilled in each eye on the morning of Day 1 and then twice a day (in the morning and in the evening, approximately 12 hours apart) starting on Day 2 for 40 consecutive days (Days 2 to 41). Thereafter, a single drop of the ophthalmic solution will be instilled in each eye on the morning of Day 42, for a total of 82 consecutive doses administered in each eye. The doses of Days 1, 2 (morning), 41 (evening), and 42 will be self-administered under supervision of the site staff at the clinical site. All remaining doses will be self-administered at home. Throughout the study, PK blood samples will be collected and safety assessments will be performed.

- Arm && Interventions
Group Intervention Description TP-03 (Lotilaner Ophthalmic Solution), 0.25% TP-03 (Lotilaner Ophthalmic Solution), 0.25% TP-03, topical ocular administration in healthy adults. Single and multiple doses for 42 days.
- Primary Outcome Measures
Name Time Method To evaluate the concentration of lotilaner in blood multiple doses of TP-03, 0.25% in whole blood following topical ocular administration in healthy adult subjects for 42 days. 42 Days The primary PK endpoints following single and multiple dose administration will include whole blood PK parameters for lotilaner Ctrough at various times
Clinically significant changes from Baseline hematology laboratory tests 42 Days Evaluate the safety of TP-03 through clinically significant changes from Baseline hematology laboratory tests
Incidence of treatment emergent adverse events (TEAEs) 42 Days Safety will be evaluated through the incidence rate of TEAEs
Clinically significant changes from Baseline physical examinations 42 Days Safety will be evaluated through review of clinically significant changes in physical examinations from Baseline
Clinically significant changes from Baseline chemistry laboratory tests 42 Days Evaluate the safety of TP-03 through clinically significant changes from Baseline chemistry laboratory tests
Clinically significant changes from Baseline electrocardiograms (ECGs) 42 Days Safety will be evaluated through review of clinically significant changes in electrocardiograms from Baseline
Clinically significant changes from Baseline vitals 42 Days Safety will be evaluated through review of clinically significant changes from Baseline vital signs (including temperature \[degrees Celsius\], pulse rate \[beats per minute\], respiration rate \[breaths per minute\], and changes in systolic and diastolic blood pressure \[mmHg\]) from Baseline
