Eligibility
Key inclusion criteria
Inclusion Criteria

- Diagnosis of type 2 diabetes mellitus , currently treated with a sulfonylurea alone
but experiencing inadequate glycemic control. Should have received the sulfonylurea
monotherapy for at least the 3 months prior to Screening; has been on a stable
sulfonylurea dose equivalent to at least 10 mg of glyburide (Exception: documented
maximum tolerated dose equivalent to less than 10 mg but at least 5 mg glyburide) for
at least 8 weeks.

- No treatment with antidiabetic agents other than a sulfonylurea within the 3 months
prior to Screening. (Exception: if a subject has received other antidiabetic therapy
for less than 7 days within the 3 months prior to Screening.)

- Body mass index greater than or equal to 23 kg/m2 and less than or equal to 45 kg/m2.

- Fasting C-peptide concentration greater than or equal to 0.8 ng/mL. (If this screening
criterion is not met, the subject still qualifies if C-peptide is greater than or
equal to 1.5 ng/mL after a challenge test.).

- Glycosylated hemoglobin concentration between 7.0% and 10.0%, inclusive.

- If regular use of other, non-excluded medications, must be on a stable dose for at
least the 4 weeks prior to Screening. However, as needed use of prescription or
over-the-counter medications is allowed at the discretion of the investigator.

than or equal to 110 mm Hg

10 g per dL for females

- Alanine aminotransferase less than or equal to 3 time the upper limit of normal.

- Serum creatinine =2.0 mg/dL (=17 micromol/L)

- Thyroid-stimulating hormone level less than or equal to the upper limit of the normal
range and the subject is clinically euthyroid.

- Neither pregnant nor lactating

- Female subjects of childbearing potential must be practicing adequate contraception.
Adequate contraception must be practiced for the duration of participation in the
study.

- Able and willing to monitor their own blood glucose concentrations with a home glucose
monitor.

from completing the study.

Key exclusion criteria
Exclusion Criteria

elevated, the subject may be rescreened within 1 week.

- History of cancer, other than squamous cell or basal cell carcinoma of the skin, that
has not been in full remission for at least 5 years prior to Screening. (A history of
treated cervical intraepithelial neoplasia I or cervical intraepithelial neoplasia II
is allowed.)

- History of laser treatment for proliferative diabetic retinopathy within the 6 months
prior to Screening.

- History of treated diabetic gastric paresis.

- New York Heart Association Class III or IV heart failure regardless of therapy.
Currently treated subjects who are stable at Class I or II are candidates for the
study.

- History of coronary angioplasty, coronary stent placement, coronary bypass surgery, or
myocardial infarction within the 6 months prior to Screening.

- History of any hemoglobinopathy that may affect determination of glycosylated
hemoglobin.

- History of infection with hepatitis B, hepatitis C, or human immunodeficiency virus.

- History of a psychiatric disorder that will affect the subject's ability to
participate in the study.

- History of angioedema in association with use of angiotensin-converting enzyme
inhibitors or angiotensin-II receptor inhibitors.

- History of alcohol or substance abuse within the 2 years prior to Screening.

- Receipt of any investigational drug within the 30 days prior to Screening or a history
of receipt of an investigational antidiabetic drug within the 3 months prior to
Screening.

- Prior treatment in an investigational study of alogliptin.

- Excluded Medications and Treatments:

- Treatment with antidiabetic agents other than study drug or glyburide is not
allowed within the 3 months prior to Screening and through the completion of the
end-of-treatment/early termination procedures.

- Treatment with weight-loss drugs, any investigational antidiabetics, Bosentan
(used for the treatment of pulmonary hypertension), or oral or systemically
injected glucocorticoids is not allowed from 3 months prior to randomization
through the completion of the end-of- treatment/early termination procedures.
Inhaled corticosteroids are allowed.

- Subjects must not take any medications, including over-the-counter products,
without first consulting with the investigator.
