About this study
Official title: Long-term Sulfonylurea Response and Glucose Control After Switching From Insulin in Children With Diabetes Due to KCNJ11 (KIR6.2) Mutations
The purpose of this study is to investigate long term response of sulfonylurea and glucose control in children with diabetes due to mutations in KCNJ11 that have been switched from insulin injections to sulfonylurea tablets.
Read the detailed description
Neonatal diabetes mellitus is a rare, monogenic form of diabetes occurring during the first 6-9 months of life characterized by hyperglycemia requiring exogenous insulin therapy. The estimated incidence is 1 per 12000 newborns. Although homozygous or compound heterozygous mutations in the genes IPF1 or GCK were the first genetic causes of this disease to be identified, activating mutations in the KIR6.2 and sulfonylurea receptor 1 (SUR1) subunits of the pancreatic ATP-sensitive K+ channel, coded for by the genes KCNJ11 and ABCC8, have recently been identified as the major causes of both transient and permanent neonatal diabetes. In the normal pancreatic beta-cell, metabolism results in increased cellular ATP, which binds to KIR6.2. The potassium channel subsequently closes and hence depolarizes the membrane initiating insulin release via increased calcium entry. Conversely, increased cellular ADP acts on SUR1 to open the channel and prevent insulin release. Activating mutations in these channels reduces sensitivity to the inhibitory actions of ATP and increases sensitivity to the stimulatory actions of ADP. This causes the ATP-sensitive K+ channel to remain open, even in the presence of glucose, therefore preventing insulin release. Sulfonylureas act by an ATP-independent mechanism to close these channels even when mutations are present. Sulfonylureas result in insulin release and were therefore immediately considered and showed to be a potential treatment option in neonatal diabetes caused by mutations in these channels. The effective replacement of insulin treatment by high-dose sulfonylureas has been shown to be successful in 90% of patients with Kir6.2 mutations and 85% of patients with SUR1 mutations resulting in improved glycemic control.
This dramatic effect of sulfonylurea is now standard, world-wide treatment in neonatal diabetes due to a mutation in either KCNJ11 or ABCC8. There is, however, far no information on long-term use of sulfonylurea in patients with KCNJ11 or ABCC8 mutations. The investigators have therefore initiated an international, multicenter, prospective study aiming to include some 75 patients aged from 9 years with a genetic diagnosis of diabetes due to a KCNJ11 gene mutation identified by sequencing in Bergen, Norway; Exeter, U.K.; Paris, France or Rome, Italy. Most patients were referred based on membership in the International Society of Pediatric and Adolescent Diabetes. All of the patients attempted transfer from treatment with insulin to a sufficient dose of sulfonylureas. No other selection criteria were applied, and all patients were included when there was outcome data following the attempted transfer. The observation period was at least 9 years after commencing sulfonylureas in all patients. The study is conducted in accordance with the Declaration of Helsinki and informed consent has been obtained from all participating patients, with parental consent given on behalf of children.

| Study group | Role | What they receive |
|---|---|---|
| Drug: Sulfonylurea | Experimental | Sulfonylurea tablets (glibenclamide, other forms of sulfonylureas) were administered at the time of intervention (before November 1, 2006).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Sulfonylurea in people with Permanent Neonatal Diabetes Mellitus, run by Haukeland University Hospital at 1 site in Norway.
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 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 Oct 2017. 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 Norway. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Sulfonylurea efficacy (time frame: Within 13 years from intervention). 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?
On the ClinicalTrials.gov record for NCT02624817, which also lists 9 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 3 Oct 2017.
