About this study

Increasing evidences suggest that infections are important etiological factors for the development of Type 1 Diabetes (T1D). The overall hypothesis of the study is that the treatment of children, during the first year after diagnosis of T1D with Azithromycin, combined with repeated episodes of intensified insulin treatment to induce maximal beta-cell rest, and dietician support to promote dietary habits that minimize the likelihood of bacterial reflux from the duodenum to the pancreatic duct, will lead to preservation of beta cell function.

This trial will examine whether the AIDIT protocol initiated within one week from diagnosis could preserve insulin production in children with Type 1 Diabetes.

Read the detailed description

The study is a 2-arm, randomized, open, single center, clinical trial. Eligible patients with type 1 diabetes will be randomized to the AIDIT protocol or treatment as usual (TAU).

All patients diagnosed with T1D and included in the study will receive standard of care. In addition, the AIDIT protocol will include 1) treatment with Azithromycin for 52 weeks using a protocol for children with cystic fibrosis, 2) repeated treatments with intensified supervised high dose insulin infusion, and 3) extra advice and support from the study dietician.

  1. Azithromycin Azithromycin will be administered orally. Azithromycin will be given three times per week for 52 weeks. The dose will be 500 mg for children with body weight ≥ 30 kg and 250 mg if body weight < 30 kg.
  2. Intensified supervised high dose insulin infusions Participants will, in addition to Azithromycin, also be subjected to intensified anti-diabetic treatment to achieve increased beta-cell rest. This will be achieved by insulin lispro given as a supervised iv infusion for 72 hours within one week of diagnosis and by subcutaneous infusion 6-8 hours during one day in study week 5, 9, 13, 17 (±1 week) and 25, 34, 43 (±2 weeks) after inclusion. The intensified treatments will aim to target a blood glucose level of 4.0 ± 0.5 mmol/l. The efficacy of the intended maximal beta cell rest will be evaluated by measurement of plasma glucose and endogenous C-peptide. If C-peptide remains positive during the supervised infusion of insulin lispro this will be interpreted as that the insulin dose needs to be increased at the next treatment occasion to achieve beta-cell rest.
  3. Dietician support Participants will receive extra advice and support from the study dietician within the first week after randomization, and after 7 and 17 weeks. Personalized nutritional advice on intake of carbohydrates, fat and protein based on four-day food records will be given to in order to reduce insulin resistance and insulin need in accordance with ISPAD guidelines. By giving nutritional advices on less volume of the meals, especially of the fluid (maximum 300 ml per meal), and by trying to extend the meal time to at least 20 minutes, the reflux into ductus pancreaticus might be reduced.

All patients will be offered an examination of their pancreas with MRI at 0 and 12 months after inclusion. In addition, plasma samples taken at inclusion and after 1.5 and 12 months will be analysed for the presence of cell-free DNA indicating ongoing cell destruction. Cell-specific methylation patterns of this cell-free DNA will be analysed to determine cell-type specific cell death.

The effect of the addition of treatment according to the AIDIT protocol will be evaluated with a Mixed Meal Tolerance Test (MMTT) to explore the effect on preservation of beta-cell function.

AIDIT protocolExperimentalTreatment as usual with the addition of: i) Azithromycin Monohydrate, three times a week (≥ 48 h between doses) during 52 weeks. 500 mg if body weight ≥ 30 kg, 250 mg if body weight < 30 kg. ii) Extra intensive insulin treatment periods for maximum beta-cell rest with Insulin lispro (Sanofi). This treatment will be given i.v. for one episode of 72 hours in the first week after inclusion and s.c. on seven 6-8 h occasions during the study year. The dose will be individually titrated to reach target blood glucose 4.0±0.5 mmol/L. ii) Dietician support; Extra advice and support from the study dietician within the first week after randomization and after 1.5 and 4 months.
Receives: Drug: Azithromycin Monohydrate; Drug: Insulin Lispro; Behavioral: Dietician support
ControlNo interventionPatients will receive treatment as usual (TAU). All patients will receive standard therapeutic treatment consisting of insulin replacement with insulin analogues aiming for normoglycemia from diagnosis. Rapid acting insulin analogue will be administered via insulin pump (continuous subcutaneous infusion) with access to insulin injections in case of malfunction in the pump system.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Azithromycin Monohydrate, Insulin Lispro and Dietician support in people with Diabetes Mellitus, Type 1 and Diabetes Mellitus, run by Uppsala University at 1 site in Sweden.

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 17 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 24 Sep 2018. 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 Sweden. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

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?

Contact Olle Korsgren, MD, PhD (+46176114187, olle.korsgren@igp.uu.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Stimulated C-peptide during an MMTT (time frame: 12 months after inclusion). 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 24 Sep 2018.
