About this study

The purpose of this study is to asses the link between glycaemic balance (summarised by HBA1C LEVEL) and specific causes of death.

Read the detailed description

The GERODIAB study is the first prospective, longitudinal follow-up cohort study, the main aim of which is to assess the link between glycaemic balance (evaluated on the basis of HbA1c levels) and total mortality at 5 years in diabetic patients aged 70 and over, and suffering from type 2 diabetes. An extension to 10 years is considered given the innovative features of this cohort follow-up procedure.

The secondary endpoints are as follows:

  • To assess the link between glycaemic balance and the mortality rate with specific causes.
  • To assess the link between glycaemic balance and the onset of or change in diabetes-related complications: cardiovascular diseases, change in renal function, diabetic retinopathy, peripheral neuropathy, perforating ulcer of the foot and acute metabolic complications.
  • To assess the link between glycaemic balance and nutritional status, the onset of or changes in cognitive disorders and a loss of autonomy.
  • To specify the role of other cardiovascular risk factors combined with glycaemic balance, in mortality, diabetes-related complications, cognitive disorders and loss of autonomy.

What is being measured

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

  1. Link between HbA1c level and the overall mortality rate at 5 years.

    The primary endpoint is to assess the link between glycaemic balance (assessed on the basis of the HbA1c level) and the overall mortality rate at 5 years for patients of 70 and over suffering from type 2 diabetes.

    Measured: 5 years

Secondary outcomes (6)
  1. Link between HbA1c level and specific causes of death.

    To assess the link between glycaemic balance (summarised by HbA1c level) and specific causes of death.

    Measured: 5 years

  2. Link between HbA1c level and the onset of or changes in diabetes-related complications

    To assess the link between glycaemic balance (summarised by HbA1c) and the onset of or changes in diabetes-related complications: - cardiovascular diseases (coronary failure, heart failure, cerebrovascular accidents, arteriopathy obliterans of the lower limbs), - change in renal function, diabetic retinopathy, peripheral neuropathy, perforating ulcer of the foot, acute metabolic complications (hypoglycaemia, diabetic ketoacidosis, hyperosmolarity).

    Measured: 5 years

  3. Link between HbA1c level and nutritional status.

    To assess the link between glycaemic balance and nutritional status.

    Measured: 5 years

  4. Link between HbA1c level and the onset of or changes in cognitive disorders.

    To assess the link between glycaemic balance and the onset of or changes in cognitive disorders.

    Measured: 5 years

  5. Link between HbA1c level and loss of autonomy.

    To assess the link between glycaemic balance and loss of autonomy.

    Measured: 5 years

  6. Role of other cardiovascular risk factors

    To specify the role of other cardiovascular risk factors (primarily, arterial hypertension, dyslipidaemia and obesity) in association with glycaemic balance on the mortality rate, diabetes-related complications, cognitive disorders and loss of autonomy.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Type 2 Diabetes, run by Association Pour la Recherche en Diabetologie et en Geriatrie.

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 6 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 10 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Results are not available in the source record.

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?

Link between HbA1c level and the overall mortality rate at 5 years. (time frame: 5 years). 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 NCT01282060, which also lists 3 linked publications.

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 Jan 2017.
