Brief Summary:
The primary purpose of this study is to evaluate the efficacy of alogliptin 25 milligram (mg) once daily compared to placebo when administered as monotherapy, or when added onto a background of metformin alone, insulin alone, or a combination of metformin and insulin, as measured by the glycosylated hemoglobin (HbA1c) change from Baseline at Week 26 in pediatric participants with type 2 diabetes mellitus (T2DM).

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Drug: Alogliptin Benzoate Drug: Placebo Phase 3

Detailed Description:

The drug being tested in this study is called alogliptin. Alogliptin is being tested to treat children 10 to 17 years of age who have T2DM and are experiencing inadequate glycemic control. This study will look at HbA1c fluctuations in children who take alogliptin in addition to their background antidiabetic therapy.

The study will enroll approximately 150 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):

  • Alogliptin 25 mg
  • Placebo (dummy inactive pill) - this is a tablet that looks like the tablet containing alogliptin 25 mg but has no active ingredient (that is, has no alogliptin).

All participants will be asked to take one tablet at the same time each day throughout the study in addition to their current background antidiabetic therapy (metformin and/or insulin) if applicable.

This multi-center trial will be conducted in the United States, Brazil, Germany, Italy, Poland, Russia, Israel and Mexico. The overall time to participate in this study is approximately 56 weeks. Participants will make multiple visits to the clinic, and will be contacted by telephone 2 weeks after the last dose of study drug for a follow-up assessment.

Primary Outcome Measures :
  1. Change From Baseline in HbA1c at Week 26 [ Time Frame: Baseline and Week 26 ]
    The change in the value of HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Week 26 relative to Baseline.

Secondary Outcome Measures :
  1. Change From Baseline in HbA1c at Weeks 12, 18, 39 and 52 [ Time Frame: Baseline and Weeks 12, 18, 39 and 52 ]
    The change in the value of HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Weeks 12, 18, 39 and 52 relative to Baseline.

  2. Percentage of Participants with Abnormal Physical Examination Findings [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
  3. Percentage of Participants With Abnormal Vital Signs Values [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
    Vital signs will include body temperature (oral or tympanic measurement), respiratory rate, blood pressure (resting more than 5 minutes), and pulse (beats per minute).

  4. Percentage of Participants with Abnormal 12-lead Electrocardiogram (ECG) Findings [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
  5. Percentage of Participants with Treatment-emergent Adverse Events (TEAE) [ Time Frame: From Day 1 to end of the study (up to 54 weeks) ]
    An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment.

  6. Percentage of Participants with Infections and Hypersensitivity Reactions [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
    Percentage of participants with infections (total) and urinary tract infections (UTIs) and respiratory tract infection (RTI) will be reported.

  7. Percentage of Participants with Hypoglycemia [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
    Mild to moderate hypoglycemia (abnormal low blood sugar) is defined as blood glucose less than (<) 60 milligram per deciliter (mg/dL) (3.33 millimole per liter [mmol/L]) in the presence of symptoms, or blood glucose <50 mg/dL (2.78 mmol/L) with or without symptoms. Severe hypoglycemia is defined as any episode requiring the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions, associated with a documented blood glucose <60 mg/dL (3.33 mmol/L) (unless the clinical situation makes obtaining a blood glucose difficult [example, it involves coma or seizure]).

  8. Percentage of Participants with Abnormal Safety Laboratory Findings [ Time Frame: From Day 1 to end of treatment period (up to 52 weeks) ]
    The percentage of participants with any abnormal standard safety laboratory values (hematology, serum chemistry, and urinalysis) will be collected throughout study.

  9. Change from Baseline in Biomarkers of Bone Turnover at Weeks 26 and 52 [ Time Frame: Baseline, Weeks 26 and 52 ]
    Biomarkers of bone turnover are bone-specific alkaline phosphatase to assess changes in bone formation and C-terminal telopeptide (CTX) to assess changes in bone resorption.

  10. Change from Baseline in CD26 Surface Antigen Levels at Weeks 26 and 52 [ Time Frame: Baseline, Weeks 26 and 52 ]
    The change in the value of CD26 surface antigen collected at Week 26 and Week 52 relative to Baseline.
