A 2-week Trial Of PF-04991532 In Patients With Type 2 Diabetes

26. září 2013 aktualizováno: Pfizer

A 2-week, Phase 1, Placebo-Controlled, Parallel Group Trial To Assess The Safety, Tolerability, Pharmacokinetics, And Pharmacodynamics Of Multiple Oral Doses Of PF-04991532 Given As Monotherapy To Adult Patients With Type 2 Diabetes Mellitus

This will be a 2-week oral dose study of PF 04991532, performed in patients with type 2 diabetes. Safety, pharmacokinetics (how the drug is distributed in the body), and pharmacodynamics (how the drug works in the body) will be studied. Patients may be asked to wash off their diabetes medication for 4-6 prior to study drug administration, and they will remain in the clinical research unit for a total of 20 days for baseline tests, 2 weeks of dosing, and some follow up tests.
