About this study

Official title: Multiple Model Probabilistic Predictive Control (MMPPC) Outpatient Clinical Protocol

This study trials a prototype artificial pancreas system that consists of a Roche insulin pump, a Dexcom continuous glucose monitor (CGM), and an experiential MMPPC (multiple model probabilistic predictive control) algorithm housed on an android cell phone. The system doses insulin based on CGM sensor glucose levels and the experimental algorithm.

The aim of this clinical study is to determine the efficacy of the MMPPC controller in adolescents and adults with type 1 diabetes in a hotel setting.

Read the detailed description

This study trials a prototype artificial pancreas system that consists of a Roche insulin pump, a Dexcom continuous glucose monitor (CGM), and an experiential MMPPC (multiple model probabilistic predictive control) algorithm housed on an android cell phone. The system doses insulin based on CGM sensor glucose levels and the experimental algorithm. The algorithm runs through a glucose control platform called the DiAs (Diabetes Assistant)

The aim of this study is to determine the safety and feasibility of the MMPPC controller in adults and adolescents with type 1 diabetes testing the use of predefined tuning parameters to provide adaptability to patient. We will assess the safety of the system with both unannounced meals, and meals using a meal announcement with a premeal insulin bolus based on the subject's estimated carbohydrate content of the meal

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MMPPC algorithm artificial pancreas in people with Type 1 Diabetes, run by Rensselaer Polytechnic Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 30 Jan 2018. 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.

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?

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?

Mean CGM glucose value (time frame: 72 hours). 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 30 Jan 2018.
