Show details

- Healthy female subjects of non-childbearing potential and/or male subjects who, at the time of screening, are 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 or clinical laboratory tests.

- Female subjects of non childbearing potential must meet at least one of the following criteria:

1. Achieved postmenopausal status, defined as follows: 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 confirming the post-menopausal state;

2. Have undergone a documented hysterectomy and/or bilateral oophorectomy;

3. Have medically confirmed ovarian failure.

- All other female subjects (including females with tubal ligations) 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 has been informed of all pertinent aspects of the study.

- Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details


- A positive urine drug screen


- Screening supine 12 lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec.
If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more
times and the average of the three QTc or QRS values should be used to determine the
subject's eligibility.


- Subjects with family history of myocardial infarction, congenital long QT syndrome,
torsades de pointes or clinically significant ventricular arrhythmias.


- Pregnant female subjects; breastfeeding female subjects; male subjects with partners
currently pregnant; male subjects able to father children who are unwilling or unable
to use two highly effective methods of contraception as outlined in this protocol for
the duration of the study and for at least 90 days after the last dose of
investigational product and, refrain from sperm donation for the duration of the study
and for at least 90 days after the last dose of investigational product.

Brief Title  ICMJE Understanding The Effect Of A Strong CYP3A4 Inducer On Glasdegib Pharmacokinetics
Official Title  ICMJE A Phase 1, Open-label, Fixed-sequence, 2-period Study In Healthy Volunteers To Investigate The Effect Of Multiple Doses Of Rifampin On Single Dose Glasdegib (Pf-04449913) Plasma Pharmacokinetics
Brief Summary The study also aims to determine the effect of a strong enzyme (CYP3A4) inducer-rifampin- on drug exposure of Glasdegib. This study will be conducted in healthy subjects given a single dose of glasdegib in each period.
