- Target Recruitment
- 92
-
Healthy male and/or female subjects of non childbearing potential between the ages of 18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests).
-
Female subjects of non childbearing potential must meet at least one of the following criteria:
- Achieved postmenopausal status, defined as: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and have a serum follicle stimulating hormone (FSH) level within the laboratory's reference range for postmenopausal females;
- Have undergone a documented hysterectomy and/or bilateral oophorectomy;
- Have medically confirmed ovarian failure. All other female subjects (including females with tubal ligations and females that do NOT have a documented hysterectomy, bilateral oophorectomy and/or ovarian failure) will be considered to be of childbearing potential.
-
Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
-
Evidence of a personally signed and dated informed consent document indicating that the subject (or a legal representative) has been informed of all pertinent aspects of the study.
-
X-ray with no evidence of current, active TB or previous inactive TB, general infections, heart failure, malignancy, or other clinically significant abnormalities taken at Screening or within 3 months prior to Day 1 and read by a qualified radiologist.
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
- Subjects with a history of or current positive results for any of the following serological tests: Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (HBcAb), anti Hepatitis C antibody (HCV Ab) or human immunodeficiency virus (HIV).
- Subjects with a history of autoimmune disorders.
- Subjects with a history of allergic or anaphylactic reaction to a therapeutic drug.
- History of tuberculosis or active, latent or inadequately treated tuberculosis infection.
- Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half lives or 180 days for biologics preceding the first dose of study medication.
- Pregnant females; breastfeeding females; and females of childbearing potential.

- Primary Outcome Measures
Name Time Method Incidence and magnitude of abnormal laboratory findings. 6 weeks Abnormal and clinically relevant changes in vital signs, blood pressure (BP) and electrocardiogram (ECG) parameters. 6 weeks Incidence of dose limiting or intolerability treatment related adverse events (AEs). 6 weeks Incidence, severity and causal relationship of treatment emergent AEs (TEAEs) and withdrawals due to treatment emergent adverse events. 6 weeks
- Secondary Outcome Measures
Name Time Method Multiple Ascending Dose Multiple Dose: Plasma Decay Half-Life (t1/2) 6 weeks Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
Multiple Ascending Dose Multiple Dose: Minimum Observed Plasma Trough Concentration (Cmin) 6 weeks Multiple Ascending Dose First Dose: Maximum Observed Plasma Concentration (Cmax) 6 weeks Single Ascending Dose: Time to Reach Maximum Observed Plasma Concentration (Tmax) 6 weeks Single Ascending Dose: Area under the plasma concentration-time profile from time zero extrapolated to infinite time (AUCinf) 6 weeks Single Ascending Dose: Area under the plasma concentration-time profile from time zero to the time of last quantifiable concentration (AUClast) 6 weeks Multiple Ascending Dose First Dose: Dose normalized Area under the plasma concentration-time profile from time zero to time τ, the dosing interval where τ=2 weeks (AUCτ [dn]) 6 weeks Single Ascending Dose: Dose normalized area under the plasma concentration-time profile from time zero extrapolated to infinite time (AUCinf[dn]) 6 weeks Single Ascending Dose: Mean residence time(MRT) 6 weeks Single Ascending Dose: Dose normalized area under the plasma concentration-time profile from time zero to the time of last quantifiable concentration (AUClast[dn]) 6 weeks Single Ascending Dose: Plasma Decay Half-Life (t1/2) 6 weeks Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
Multiple Ascending Dose First Dose: Area under the plasma concentration-time profile from time zero to time τ, the dosing interval where τ=2 weeks (AUCτ) 6 weeks Multiple Ascending Dose Multiple Dose: Apparent Volume of Distribution (Vz/F) 6 weeks Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
Multiple Ascending Dose Multiple Dose: Systemic Clearance (CL) 6 weeks CL is a quantitative measure of the rate at which a drug substance is removed from the body.
Multiple Ascending Dose Multiple Dose: Observed accumulation ratio (Rac) 6 weeks Multiple Ascending Dose Multiple Dose: Peak to trough fluctuation (PTF) 6 weeks Single Ascending Dose: Area under the plasma concentration-time profile from time zero to 14 days (AUC14 days) 6 weeks Single Ascending Dose: Dose normalized maximum plasma concentration (Cmax[dn]) 6 weeks Multiple Ascending Dose First Dose: Mean residence time (MRT) 6 weeks Multiple Ascending Dose First Dose: Systemic Clearance (CL) 6 weeks CL is a quantitative measure of the rate at which a drug substance is removed from the body.
