Improving HbA1c Levels Through Behavioural Change of Diabetes Self-management Assisted by the LovedBy Mobile Application for Young Adults and Adolescents With Type 1 Diabetes — LBY-T1  

Diabetes Mellitus, Type 1 Clinical Trial

Official title: A Single-centre, Randomised, Cross-over Design Efficacy Study to Assess the Effectiveness of App-based, Assisted Behavioural Change Techniques to Improve HbA1c Levels and Support Diabetes Self-management in Young Adults and Adolescents

Status Recruiting

Clinical Trial Summary

Young people (16-25) with type-1 diabetes have historically struggled with managing their condition. Typically, the average HbA1c levels are significantly higher and as such, the risk of long term complications tend to be far greater.

These sufferers tend to have better management of their condition as they grow older however, the evidence suggests this is too late and these sufferers will likely have some complications later in life. Current cost to the NHS for complications is ~£850 million and expected to rise to ~£1.3 billion in the next 10-15 years.

The LovedBy solution aims to leverage modern technologies such as smartphones, continuous glucose monitors (CGM), and other smart wearables to assist young sufferers managing their condition. The LovedBy platform offers a mobile application which connects to the user's smart wearables and CGM to monitor data streams that have been linked to long term risk. The mobile application is then able to deliver personally relevant educational content to the user through numerous channels including private social media messages.

The study will last 10 months, and the participants are required to download/install the mobile app, integrate their wearables and then simply continue as normal with regular clinical meetings. Participants will be between 16-25 years and comply with the inclusion criteria set out in the protocol.

Clinical Trial Description

This study will recruit 40 participants suffering from type-1 diabetes, split across 2 groups, with 30 needed for statistical significance (10 extra to allow for dropouts). The participant will have their average HbA1c levels measured (lab based, CONTROL-1). While the participants are participating in the trial, they will receive relevant educational content based on areas of management they are struggling with. The analysis that decides this is automated by the system which explores whether the particular criteria have been met for each educational pieces.

At the end of the study we will be able to compare whether the primary outcome has been met by comparing a final average HbA1c measure to CONTROL-1. Secondary outcomes can be evaluated using the sensor HbA1c recordings.

The entire study can be summarised as a reference to a reduction in long term risk and cost saving to the NHS.

Participant Journey

Pre-Trial (Visit 1):

1-3 hours 2-4 weeks before study starts Firstly, the patient will be sent all relevant study documents after which there is the recruitment call where the study will be described in detail. All risks will be discussed here and made clear. The data policies and management of data will also be described here. The patient will be able to ask any questions they wish to do so at this point.

If the patient is willing to participate in the trial, consent will be obtained after the they have had adequate time to reflect on the study.

Once consent has been obtained, the participant will be able to undergo lab HbA1c sampling. The participant will also undertake a questionnaire (Diabetes Distress Scale). The questionnaire will be undertaken at intervals between the other tasks during this visit.

Trial (Visit-2):

1-2 hours Study starts The clinical research team (CRT) will collect various measures such as weight, height blood pressure, body fat etc.and also ensure the users CGM is set up correctly.

Test-Group: The CGM will be integrated with the users mobile handset and all relevant measures taken will be entered. Participant will be provided with a smart watch and this will also be integrated with the users smartphone.

The user will then download and install the LovedBy mobile app. Once installed the user will set up an account and the account number will be recorded by the clinical research team to track the participant throughout the trial. The final step is to review the permissions of the mobile application and allow the mobile application to connect to the users handset. Control-Group: The same measurements will be taken as with the test group but here no app will be provided to the participants in this group.

Trial (Visit-3):

1-2 hours 8-weeks since last visit Test-Group: Participants of this group will undergo an interview with clinical research team. They will discuss events that were identified by the LovedBy platform. The CRT will also update the measures taken in the previous visit. The participant will also be asked to partake in a semi-structured interview to asses phycological efficacy.

Control-Group: This group will not undergo an interview.

Trial (Visit-4):

1-2 hours 8-weeks since last visit All participants will end the first arm of the study with lab HbA1c recorded. They will then proceed with a 4-week washout period. After which they will cross-over to begin the second arm of the study.

Trial (Visit-5):

1-2 hours 4-weeks since last visit This visit will be identical to Visit-2 but the Test-Group and Control-Group will switch over.

Trial (Visit-6):

1-2 hours 8-weeks since last visit This visit will be identical to Visit-3 where only the Test-Group will be interviewed.

Trial (Visit-7):

1-2 hours 8-weeks since last visit All participant will undergo a lab HbA1c sampling. The participant will undergo an exit interview regarding their experience with and without the LovedBy app. During this exit interview all LovedBy resources provided to the user such as smartwatches, CGM and applications will be handed back and/or removed from the user's device. The interview will aim to better capture the qualitative efficacy of the platform. It will be analysed to identify areas of design improvements that can be made on the user interface and content pieces.
