  25. Incidence of Hypoglycaemic Episodes - Glycaemia Above or Equal to 0.56 g/L

    Number of "symptoms only" hypoglycaemic episodes from Week 0 to Week 8, defined as self-measurement plasma glucose higher than or equal to 3.1 mmol/L (56 mg/dL) or no plasma glucose measurement and the child is able to treat her/himself.

    Measured: Weeks 0-8

  26. Percentage of Children Assessing Insulin Therapy Injection Pain as "Sad Face"

    Via a paper diary, the children perceived insulin therapy injection pain by using a four-grade facial visual analogue scale (VAS): very sad face, sad face, happy face or very happy face.

    Measured: Week 0 and Week 8

  27. Percentage of Children Assessing Insulin Therapy Injection Pain as "Happy Face"

    Via a paper diary, the children perceived insulin therapy injection pain by using a four-grade facial visual analogue scale (VAS): very sad face, sad face, happy face or very happy face.

    Measured: Week 0 and week 8

  28. Percentage of Children Assessing Insulin Therapy Injection Pain as "Very Happy Face"

    Via a paper diary, the children perceived insulin therapy injection pain by using a four-grade facial visual analogue scale (VAS): very sad face, sad face, happy face or very happy face.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing insulin detemir and insulin aspart in people with Diabetes and Diabetes Mellitus, Type 1, run by Novo Nordisk A/S at 1 site in France.

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 5 inclusion and 4 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 3 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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 18 Jan 2013). 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?

Glycosylated Haemoglobin A1c (HbA1c) (time frame: Week 0 and Week 8). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Nov 2014.
