Pharmacokinetics and Pharmacodynamics Study of Alogliptin in Healthy Korean Participants

A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Single and Multiple-Dose Study of the Pharmacokinetics and Pharmacodynamics of Alogliptin 12.5 mg, 25 mg and 50 mg in Healthy Korean Subjects

The purpose of this study is to assess the Pharmacokinetics and Pharmacodynamics of alogliptin after a single or multiple administrations, once daily (QD), of oral alogliptin in healthy Korean subjects.

Study Overview

• Status: Completed
• Conditions: Pharmacokinetics and Pharmacodynamics
• Intervention / Treatment: Drug: Alogliptin; Drug: Alogliptin; Drug: Alogliptin

Detailed Description

Alogliptin is a selective, orally available inhibitor of dipeptidyl peptidase-4 being developed by Takeda Global Research & Development Center, Inc. as a treatment for type 2 diabetes mellitus. Inhibition of dipeptidyl peptidase-4 (DPP-4) prolongs the action of 2 important incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). These hormones are responsible for increasing insulin synthesis, regulating β-cell proliferation, inhibiting gastric emptying and inhibiting glucagon secretion.

Evaluations of alogliptin and its clinical efficacy have been conducted in multiple countries including the United States and Japan. As development of alogliptin expands to other countries, additional studies are needed to bridge between the data previously acquired.

The main objective of this study is to assess the pharmacokinetics and pharmacodynamics of alogliptin in healthy Korean participants.

Exclusion Criteria:

1. The participant has received any investigational compound within 30 days prior to Screening.
2. The participant has received alogliptin in a previous clinical study or as a therapeutic agent.
3. The participant is an immediate family member, study site employee, or in a dependant relationship with a study site employee who is involved in the conduct of this study (e.g., spouse, parent, child, sibling) or may consent under duress.
4. The participant has history of uncontrolled, clinically significant manifestations of metabolic (including diabetes mellitus, hypercholesterolemia, or dyslipidemia), endocrine, hematologic, pulmonary, cardiovascular, gastrointestinal, neurological, rheumatologic, skin and subcutaneous tissue disorders, infectious, hepatic, renal, urologic, immunologic, psychiatric or mood disorders (including any past history of suicide attempt), or a history of lactose intolerance, which may impact the ability of the participant to participate or potentially confound the study results.
5. Participant has a known hypersensitivity to any component of the formulation of alogliptin.
6. The participant has a positive urine drug result for drugs of abuse or alcohol at Screening or Check-in (Day -1).
7. The participant has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse within 1 year prior to the Screening visit or is unwilling to agree to abstain from alcohol and drugs throughout the study.

9. If female, the participant is pregnant or lactating or intending to become pregnant before, during, or within 30 days after participating in this study; or intending to donate ova during such time period.
10. If male, the participant intends to donate sperm during the course of this study or for 12 weeks after the last dose.
11. Participant has evidence of current cardiovascular, central nervous system, hepatic, hematopoietic disease, renal dysfunction, metabolic or endocrine dysfunction, serious allergy, asthma hypoxemia, hypertension, seizures, or allergic skin rash. There is any finding in the participant's medical history, physical examination, or safety laboratory tests giving reasonable suspicion of a disease that would contraindicate taking alogliptin, or a similar drug in the same class, or that might interfere with the conduct of the study. This includes, but is not limited to, peptic ulcer disease, seizure disorders, and cardiac arrhythmias.
12. Participant has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs (i.e., a history of malabsorption, esophageal reflux, peptic ulcer disease, erosive esophagitis frequent [more than once per week] occurrence of heartburn, or any surgical intervention [e.g., cholecystectomy]).
13. Participant has a history of cancer, except basal cell carcinoma which has been in remission for at least 5 years prior to Day 1.
14. Participant has a positive test result for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCV), or a known history of human immunodeficiency virus infection at the Screening visit.
15. Participant has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 28 days prior to Check-in Day -1. Cotinine test is positive at Screening or Check-in (Day -1).
16. The participant has poor peripheral venous access.
17. Participant has donated or lost 450 mL or more of his or her blood volume (including plasmapheresis), or had a transfusion of any blood product within 30 days prior to Day 1.
18. Participant has a Screening or Check-in (Day -1) abnormal (clinically significant) electrocardiogram (ECG). Entry of any participant with an abnormal (not clinically significant) ECG must be approved, and documented by signature by the principal investigator.
19. Participant has abnormal Screening or Day -1 laboratory values that suggest a clinically significant underlying disease or participant with the following lab abnormalities: alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) >2x the upper limits of normal.
20. Participant has a hemoglobin value <12 g/dL at Screening only.
21. Participant has a systolic blood pressure ≥140 mm Hg or has a diastolic blood pressure ≥90 mm Hg at Screening or Check-in (Day -1).
