About this study

Official title: A 16-week, Open-label, Multicentre, Randomised, Parallel Study to Evaluate Efficacy and Safety of Repaglinide and Metformin Combination Therapy Compared to Repaglinide Monotherapy in Chinese OAD Naive Type 2 Diabetic Patients

This trial is conducted in Asia. The aim of this clinical trial is to investigate the blood sugar lowering effect of repaglinide plus metformin as initial treatment compared to repaglinide alone in Chinese subjects with type 2 diabetes having an HbA1c (glycosylated haemoglobin A1c) over 8.5 % and who never have taken oral sugar-lowering drugs before. The associated unfavourable events including low blood sugar episodes between the two treatments are also compared.

What is being measured

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

  1. Change in Glycosylated Haemoglobin A1c (HbA1c)

    Calculated as an estimate of the mean change in HbA1c after 16 weeks of treatment.

    Measured: week -2 (screening), week 16

Secondary outcomes (14)
  1. Change in Fasting Plasma Glucose

    Calculated as an estimate of the mean change in fasting plasma glucose after 16 weeks of treatment.

    Measured: week 0, week 16

  2. Change in 2-hour Postprandial Plasma Glucose

    Calculated as an estimate of the mean change in 2-hour postprandial plasma glucose following a standard test meal after 16 weeks of treatment

    Measured: Week 0, week 16

  3. Change in 7-point Plasma Glucose Profile

    Calculated as an estimate of the mean change in 7-point (before breakfast, 2 hours after breakfast, before lunch, 2 hours after lunch, before dinner, 2 hours after dinner, bedtime) plasma glucose profile after 16 weeks of treatment.

    Measured: Week 0, week 16

  4. Change in Fasting Serum Insulin

    Calculated as an estimate of the mean change in fasting serum insulin after 16 weeks of treatment.

    Measured: Week 0, week 16

  5. Change in 2-hour Postprandial Serum Insulin

    Calculated as an estimate of the mean change in 2-hour postprandial serum insulin after 16 weeks of treatment.

    Measured: Week 0, week 16

  6. Change in Fasting Serum C-peptide

    Measured: Week 0, week 16

  7. Change in 2-hour Postprandial Serum C-peptide

    Calculated as an estimate of the mean change in 2-hour postprandial serum C-peptide after 16 weeks of treatment

    Measured: Week 0, week 16

  8. Hypoglycaemic Episodes

    Number of hypoglycaemic episodes from Week 0 to Week 16, defined as major, minor or symptoms only. Major if unable to treat her/himself. Minor if able to treat her/himself and plasma glucose below 3.1 mmol/L. Symptoms only if able to treat her/himself and no plasma glucose measurement or plasma glucose higher than or equal to 3.1 mmol/L.

    Measured: Weeks 0-16

  9. Change in Blood Pressure

    Calculated as the mean change in diastolic and systolic blood pressure after 16 weeks of treatment

    Measured: Week 0, week 16

  10. Physical Examinations

    The number of subjects having a physical examination event that changed from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant'. Physical examination included cardiovascular system, respiratory system, musculoskeletal system, nervous system and abdomen.

    Measured: Week -2, week 16

  11. ECG (ElectroCardioGram)

    The number of subjects having a electrocardiogram (ECG) that changed from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant'. 'Abnormal, Clinically significant' is an abnormality that suggests a disease and/or organ toxicity and is of a severity, which requires active management.

    Measured: Week -2, week 16

  12. Biochemistry: Alanine Aminotransferase (ALAT)

    The number of subjects having a change in Alanine Aminotransferase (ALAT) from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant'. 'Abnormal, Clinically significant' is an abnormality that suggests a disease and/or organ toxicity and is of a severity, which requires active management.

    Measured: Week -2, week 16

  13. Biochemistry: Alanine Aminotransferase (ASAT)

    The number of subjects having a change in Aspartate Aminotransferase (ASAT) from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant'. 'Abnormal, Clinically significant' is an abnormality that suggests a disease and/or organ toxicity and is of a severity, which requires active management.

    Measured: Week -2, week 16

  14. Haematology: Haemoglobin

    Haemoglobin was measured. The number of subjects having a change in Haemoglobin measurement from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant' 'Abnormal, Clinically significant' is an abnormality that suggests a disease and/or organ toxicity and is of a severity, which requires active management.

    Measured: Week -2, week 16

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing repaglinide and metformin in people with Diabetes and Diabetes Mellitus, Type 2, run by Novo Nordisk A/S at 17 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Dec 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Glycosylated Haemoglobin A1c (HbA1c) (time frame: week -2 (screening), week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00819741, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2017.
