Inclusion Criteria
  • Healthy adult male and female subjects, 18-65 years of age inclusive
  • BMI 18 to 32 kg/m2 inclusive
  • Female subjects must be surgically sterile or postmenopausal for the past year and have a negative urine pregnancy test. Male subjects and their partners of childbearing potential must be willing to use two methods of contraception, one of which must be a barrier method (e.g. condom) for up to 90 days after the last study drug administration.
  • Willing and able to remain in the clinical research unit as required by the protocol
  • Willing and able to provide written informed consent prior to any study related procedures and to comply with all study requirements
Exclusion Criteria
  • History or presence of significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, or psychiatric disease
  • History or presence of any disease, medical condition, or surgery, which may have an effect on drug absorption, metabolism, distribution, or excretion of the investigational product
  • Laboratory test results (including hepatic and renal panels, complete blood count, chemistry panel, and urinalysis) that the investigator believes show clinically relevant significant abnormalities for the normal reference range
  • Any abnormality in the ECG (including QTc ≥450 msec) that in the opinion of the investigator increases the risk of participating in the study
  • History or presence of alcoholism or drug abuse within the year prior to dosing
  • Tobacco use, either current or within 3 months prior to dosing
  • Use of any prescription medications or herbal remedies within 14 days prior to dosing, or use of over-the-counter medications or vitamins within 7 days prior to dosing, unless approved by the Sponsor
  • Donation of whole blood within 56 days prior to the study
  • Plasma donation within 7 days prior to the study
  • Participation in an investigational device study or receipt of an investigational drug within 4 weeks prior to dosing
  • Positive urine test for drugs of abuse
  • Confirmed HIV, hepatitis B, or hepatitis C infection

Primary Outcome Measures
NameTimeMethod
Safety-Number of patients with adverse events7 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 events7 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
NameTimeMethod
Pharmacokinetic profile: Measurement of area under the plasma-concentration-time curve7 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 Concentration7 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 constant7 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).
