About this study

Official title: Observational, Prospective, Parallel Cohort Study to Evaluate Tolerability of Canagliflozin and Sulphonylurea on a Background Therapy of Metformin With or Without a DPP-4 Inhibitor During Ramadan Fasting in Patients With Type 2 Diabetes

The primary purpose of this study is to describe the tolerability of canagliflozin and any sulphonylurea (each administered with metformin with or without a DPP-4 inhibitor), in terms of the percentage of patients with at least one episode of hypoglycaemia, in patients with T2DM who fast during Ramadan.

Read the detailed description

This is non-randomized, parallel-cohort, prospective, multicenter (when more than one hospital works on a medical research study), observational study to describe the treatment of T2DM with canagliflozin during the Holy Month of Ramadan. Observed participants will be participants with T2DM (at the time of enrollment) who are being treated with either canagliflozin or any sulphonylurea, each administered on a background therapy of metformin with or without a DPP-4 inhibitor within clinical practice, and who intend to fast during the Ramadan period. On enrollment, patients will enter one of two parallel treatment cohorts based on their ongoing T2DM therapy: canagliflozin and metformin with or without a DPP-4 inhibitor will be the treatment of interest, while any sulphonylurea and metformin with or without a DPP-4 inhibitor will serve as the reference standard treatment. Safety will be monitored throughout the study.

Cohort 1Participants who are already receiving Canagliflozin and Metformin with or without a DPP-4 inhibitor daily during Ramadan period will be observed as the part of study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With at Least one Episode of Hypoglycaemia

    Hypoglycaemia events are defined by symptoms (e.g., dizziness, visual blurring, palpitations, nausea, sweating, confusion, tremor or intense hunger) reported by the patient in the patient diary, with confirmation by a physician where applicable; Episode may be documented via a self-monitored blood glucose measurement <70 milligram/deciliter (mg/dl).

    Measured: during the Ramadan period (up to 1 month)

Secondary outcomes (11)
  1. Number of Participants With Volume Depletion Events

    Measured: during the Ramadan period (up to 1 month)

  2. Treatment Adherence Based on the Percentage of Prescribed Doses of Canagliflozin or Sulphonylurea Taken by Participants

    Measured: during the Ramadan period (up to 1 month)

  3. Time to the First Hypoglycaemia Event

    Measured: during the Ramadan period (up to 1 month)

  4. Relationship of Hypoglycaemia Events With Clinical Parameters

    Precipitating factors, symptoms and blood glucose concentration during hypoglycaemia episode will be described.

    Measured: during the Ramadan period (up to 1 month)

  5. Relationship of Hypoglycaemia Events With Used Treatment

    Causal relationship of hypoglycaemia event to treatment will be evaluated.

    Measured: during the Ramadan period (up to 1 month)

  6. Relationship of Hypoglycaemia Events With Treatment Adherence

    Treatment adherence will be based on the percentage of prescribed doses of canagliflozin or sulphonylurea that are missed during the Ramadan period, as reported in the patient diary. Any changes in study medication (i.e. missed or delayed dosing) due to hypoglycaemia events will be captured.

    Measured: during the Ramadan period (up to 1 month)

  7. Relationship of Hypoglycaemia Events With Number of Fasting Days

    Number of days when fasting was broken due to hypoglycaemia or hypoglycaemia prevention will be captured.

    Measured: during the Ramadan period (up to 1 month)

  8. Relationship of Volume Depletion Events With Clinical Parameters

    Precipitating factors, symptoms and blood glucose concentration during volume depletion related adverse events will be described.

    Measured: during the Ramadan period (up to 1 month)

  9. Relationship of Volume Depletion Events With Used Treatment

    Causal relationship of volume depletion related adverse event to treatment will be evaluated.

    Measured: during the Ramadan period (up to 1 month)

  10. Relationship of Volume Depletion Events With Treatment Adherence

    Treatment adherence will be based on the percentage of prescribed doses of canagliflozin or sulphonylurea that are missed during the Ramadan period, as reported in the patient diary. Any changes in study medication (i.e. missed or delayed dosing) due to Volume depletion related adverse events will be captured.

    Measured: during the Ramadan period (up to 1 month)

  11. Relationship of Volume Depletion Events With Number of Fasting Days

    Number of days when fasting was broken due to the volume depletion related adverse event will be reported.

    Measured: during the Ramadan period (up to 1 month)
