Study Details
Study Description
Brief Summary
The purpose of this study is to study the safety and tolerability of a single dose of PLX5622 in healthy, adult human volunteers. This will be the first time PLX5622 has been taken by humans.

Outcome Measures
Primary Outcome Measures
- Safety-Number of patients with adverse events [7 days]
Subjects will take one oral dose of PLX5622 on Day 1. Physical examinations, vital signs, 12-lead electrocardiograms (ECG), adverse events, hematology, serum chemistry, coagulation, and urinalysis will be used to assess safety throughout the Days 1-4 of the study and on the follow up study visit on day 7. Adverse events will be monitored and reviewed for safety issues/abnormal changes in the above mentioned tests.
- Tolerability-Number of patients with adverse events [7 days]
Subjects will take one oral dose of PLX5622 on Day 1. Physical examinations, vital signs, 12-lead electrocardiograms (ECG), adverse events, hematology, serum chemistry, coagulation, and urinalysis will be used to assess safety throughout the Days 1-4 of the study and on the follow up study visit on day 7. Adverse events will be monitored and reviewed for tolerability issues/abnormal changes in the above mentioned tests.
Secondary Outcome Measures
- Pharmacokinetic profile: Measurement of area under the plasma-concentration-time curve [7 days]
Pharmacokinetic (PK) samples will be collected prior to dosing and at 0.5, 1, 2, 4, 8, 12, 24, 26, 48, 60 and 72 hours following dosing. The pharmacokinetic profile of plasma PLX5622 will be analyzed by measurement of area under the plasma concentration-time curve [AUC0-t, AUC0-inf, AUC0-24].
- Pharmacokinetic evaulation: Measurement of Peak Concentration [7 days]
Pharmacokinetic (PK) samples will be collected prior to dosing and at 0.5, 1, 2, 4, 8, 12, 24, 26, 48, 60 and 72 hours following dosing. The pharmacokinetic profile of plasma PLX5622 will be analyzed by measurement of peak concentration (Cmax) and time to peak concentration (Tmax).
- Pharmacokinetic profile: Measurement of half life and terminal elimination rate constant [7 Days]
Pharmacokinetic (PK) samples will be collected prior to dosing and at 0.5, 1, 2, 4, 8, 12, 24, 26, 48, 60 and 72 hours following dosing. The pharmacokinetic profile of plasma PLX5622 will be analyzed by measurement of half-life (T1/2), and terminal elimination rate constant (Kel).
