About this study

Official title: Effect of Vitamin D Supplementation on Rate of Partial Clinical Remission in Children and Adolescents With Type 1 Diabetes

The purpose of this study is to determine if supplementation with Vitamin D in children and adolescents with newly diagnosed type 1 diabetes increases the number of patients who enter the honeymoon period.

Read the detailed description

Type 1 diabetes is an autoimmune disease characterized by destruction of the insulin secreting beta-cells of the pancreas. There is evidence that Vitamin D may play a role in the initial risk of development of autoimmune disease, including type 1 diabetes. However, Vitamin D may also play a role the natural progression of type 1 diabetes by altering innate insulin secretion and sensitivity and by influencing systemic inflammation, directly at the level of the beta-cell. Studies have shown that Vitamin D insufficiency or deficiency is frequently reported in children and adolescents with type 1 diabetes. A majority of newly diagnosed patients with type 1 diabetes enter a period of partial clinical remission, characterized by low or even absent insulin requirements, also known as a honeymoon period. This honeymoon period is associated with improved metabolic control, near normal insulin sensitivity, and recovery of beta-cell function leading to preservation of endogenous insulin secretion. We hypothesize that supplementation with Vitamin D in children and adolescents with newly diagnosed type 1 diabetes will halt the destructive process within the beta cell and improve beta-cell function by increasing endogenous insulin secretion and decreasing systemic inflammation, thereby increasing the rate of partial clinical remission.

What is being measured

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

  1. IDAA1c

    Our primary outcome measure will be to determine the rate of partial clinical remission at 9 months of disease duration, which will be assessed by determining insulin dose adjusted hemoglobin A1c (IDAA1c) using the formula (HbA1c% + [4 x insulin dose u/kg/day]). A IDAA1c <9 will be indicative of partial clinical remission.

    Measured: 9 months disease duration

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin D in people with Type 1 Diabetes, run by Nationwide Children's Hospital at 1 site in United States.

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 1 inclusion and 5 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 28 Feb 2024. 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 United States. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 28 Feb 2024). 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?

IDAA1c (time frame: 9 months disease duration). 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 28 Feb 2024.
