  Purpose
The purpose of this study is to compare the results from two methods used to determine the renal threshold for glucose excretion (defined as the lowest plasma glucose concentration at which appreciable amounts of glucose appear in the urine) in untreated patients with type 2 diabetes mellitus and in patients with type 2 diabetes mellitus who are treated with 100 mg once-daily canigliflozin for 8 days.

Condition Intervention Phase
Diabetes Mellitus, Type 2 Drug: Canagliflozin Phase 1

Study Type: Interventional
Study Design: Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label Study to Compare Two Methods for Determining the Renal Threshold for Glucose in Subjects With Type 2 Diabetes Mellitus

Primary Outcome Measures:
  • RTG values using the MMTT and the stepwise hyperglycemic clamp methods [ Time Frame: On Days 1 and 2 (Part 1) ]
  • RTG values using the MMTT and the stepwise hyperglycemic clamp methods [ Time Frame: On Days 7 and 8 (Part 2) ]

Secondary Outcome Measures:
  • Plasma glucose (PG) concentration during the MMT and the hyperglycemic clamp procedure [ Time Frame: On Days 1 and 2 (Part 1) ]
  • Plasma glucose (PG) concentration during the MMT and the hyperglycemic clamp procedure [ Time Frame: On Days 7 and 8 (Part 2) ]
  • Rate of Urinary glucose excretion (UGE) during the MMTT and the hyperglycemic clamp procedure [ Time Frame: On Days 1 and 2 (Part 1) ]
  • Rate of Urinary glucose excretion (UGE) during the MMTT and the hyperglycemic clamp procedure [ Time Frame: On Days 7 and 8 (Part 2) ]

Enrollment: 28
Study Start Date: January 2011
Study Completion Date: July 2011
Arms Assigned Interventions
No Intervention: Part 1: no Intervention
In Part 1 of the study, patients will not receive any study drug.
Experimental: Part 2: canagliflozin
In Part 2 of the study, patients will receive canagliflozin once daily on Days 1 through 8.
Drug: Canagliflozin
One 100 mg capsule taken orally (by mouth) on Days Days 1-8

Detailed Description:
This is an open-label (patients will know if they are receiving treatment and the identity of the treatment) study that will compare renal threshold of glucose (RTG) values obtained by 2 different methods: an established method (ie, the stepwise hyperglycemic clamp method) and a new method (the mixed meal tolerance test [MMTT] method). The RTG is defined as the lowest plasma glucose concentration at which appreciable amounts of glucose appear in the urine. Each method for determining the RTG value will be performed in untreated patients with type 2 diabetes mellitus (T2DM) and in patients with T2DM who are treated with canagliflozin 100 mg once daily for 8 days. Canagliflozin (a Sodium-Glucose Cotransporter 2 inhibitor) is currently under development to lower blood sugar levels in patients with T2DM. Patients will not take study drug (canagliflozin 100 mg overencapsulated tablets) in Part 1 of the study. In Part 2 of the study, patients will take study drug once daily on Study Days 1 through 8.
