A Study Of Glasdegib In Healthy Volunteers To Establish The Bioequivalence Of The Phase 2 Formulation To The ICH Formulation

Inclusion Criteria:

- Healthy male and/or female subjects of non-child bearing potential 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 nonchildbearing
potential must meet at least 1 of the following criteria:

1. Achieved postmenopausal status, defined as follows: cessation of regular menses
for at least 24 consecutive months with no alternative pathological or
physiological cause; with a serum follicle-stimulating hormone (FSH) level
confirming the postmenopausal 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 and females that do NOT have a documented
hysterectomy, bilateral oophorectomy and/or ovarian failure) are 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 lb).

- 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:

- A positive urine drug test.

- Screening supine 12-lead ECG demonstrating a corrected QT (QTc) interval >450 msec or
a QRS interval >120 msec. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG
should be repeated 2 more times and the average of the 3 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. Subjects
should be within normal range of potassium, magnesium and corrected calcium
calculation at screening.

- Pregnant female subjects; breastfeeding female subjects; female subjects of
childbearing potential; male subjects with partners currently pregnant; male subjects
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.
