Trial summary

The researchers are working with a technology company, AiCure, to develop a smartphone app, DOT Diary, which combines two drug adherence strategies. DOT Diary reminds people when it is time to take their medication, and uses motion-sensing technology to visually and automatically confirm the pill was swallowed. Read more about this study

About this study

Official title: DOT Diary (D2): Developing a Mobile App With Combined Automated DOT and Daily Sexual Diary for Monitoring and Improving PrEP Adherence: DOT Diary Optimization Pilot

The researchers are working with a technology company, AiCure, to develop a smartphone app, DOT Diary, which combines two drug adherence strategies. DOT Diary reminds people when it is time to take their medication, and uses motion-sensing technology to visually and automatically confirm the pill was swallowed. The goal of this study is to understand people's experiences using this new app while taking HIV pre-exposure prophylaxis (PrEP) for the prevention of HIV.

Read the detailed description

In the DOT Diary research project, the AiCure aDOT smartphone app has been adapted for use in monitoring and supporting HIV pre-exposure prophylaxis (PrEP) use among young men who have sex with men (YMSM). The aDOT app uses automated directly observed therapy (DOT) that use the smartphone camera and artificial intelligence software to confirm that the right person is taking the right medication at the right time. A sexual diary has been integrated into the aDOT app to assist YMSM in understanding whether they are receiving protection from PrEP for individual sexual episodes, and when it is particularly important to take PrEP (e.g. after a sexual episode).

In the next stage of app development, the researchers are conducting this study to identify areas of the app that require refinement to maximize the acceptability and ease of use of the DOT adherence monitoring app. The researchers will assess overall acceptability and ease of use of the integrated DOT Diary (D2) app over an 8 week period.The goal of this pilot study will be to refine and optimize the app for further testing in a larger and longer pilot study among YMSM at risk for HIV acquisition. The researchers will conduct this pilot protocol among YMSM in Atlanta and San Francisco Bay Area, two metropolitan regions heavily impacted by HIV, yet differing in sociodemographics, as well as in the availability and uptake of HIV prevention services, including PrEP. These diverse research locations will allow collection of data to inform app development among a broad group of YMSM.

What is being measured

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

  1. DOT Diary Mobile App Acceptability

    System Usability Scale (SUS) is a 10 item questionnaire with 5 response options: strongly disagree to strongly agree. These are scored 0-4. The scores are then summed up (making sure all positive responses -- increased usability -- are given the higher scores). The final score is multiplied by 2.5 Possible scores are from 0-100, with maximal usability achieving the higher score. Although the scores are 0-100, these are not percentages and should be considered only in terms of their percentile ranking.

    Measured: 8 weeks

  2. DOT Diary Mobile App Ease of Use

    5-point Likert scale (1=strongly disagree that app is easy to use; 5=strongly agree that app is easy to use) on a single question of the key attribute of ease of use of DOT Diary over 8 weeks by MSM on PrEP.

    Measured: 8 weeks

  3. Adherence and Persistence of Use of the DOT and Sexual Diary Components of DOT Diary by Young MSM on PrEP

    Adherence and Persistence of use of the DOT and sexual diary components of DOT Diary by young MSM on PrEP is measured by the percentage of doses taken with visual confirmation of pill ingestion

    Measured: 8 weeks

Secondary outcomes (1)
  1. Assessment of Situations and Reasons for Sub-optimal Use of the App

    Combined analysis of situations and reasons for sub-optimal use of the app, for the purpose of app optimization

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Emtricitabine / Tenofovir Disoproxil Oral Tablet and DOT Diary mobile app in people with Adherence, Medication and Risk Behavior, run by Public Health Foundation Enterprises, Inc. at 2 sites 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 16 inclusion and 9 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 27 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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?

Yes. Results are posted in the registry (first posted 19 Feb 2020). 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?

DOT Diary Mobile App Acceptability (time frame: 8 weeks). The study lists 3 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 NCT03387462, which also lists 1 linked publication.

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 27 Oct 2021.
