What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to evaluate the effectiveness of a digital app used alongside regular treatment for people with schizophrenia, particularly those experiencing negative symptoms such as lack of motivation or social withdrawal. The researchers seek to determine if the app remains effective and safe for individuals who participated in a previous study. Participants must have completed the earlier related trial and need access to a smartphone with internet to use the app. As a Phase 3 trial, this study represents the final step before FDA approval, providing participants an opportunity to contribute to a potentially groundbreaking treatment.

Do I need to stop my current medications for this trial?

The trial protocol does not specify if you need to stop your current medications. It seems you can continue your standard care medications while participating.

Do I need to stop my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. It seems likely that you can continue your existing medications, but it's best to confirm with the study team.

What prior data suggests that this digital therapeutic is safe for schizophrenia?

Research has shown that the Study App is generally safe for people with schizophrenia. A recent study reported no problems caused by the app and no serious issues that required stopping the study. This indicates that most users handle the app well. While this is encouraging, ongoing studies continue to carefully monitor safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for schizophrenia?

Unlike traditional treatments for schizophrenia, which often rely on medications like antipsychotics to manage symptoms, the digital therapeutic app offers a novel approach by serving as an adjunct to standard care. This app targets experiential negative symptoms of schizophrenia, such as social withdrawal and lack of motivation, which are typically harder to treat with medication alone. Researchers are excited because this digital therapeutic can provide personalized, interactive support right from a smartphone, potentially enhancing patient engagement and improving outcomes without additional side effects.

What evidence suggests that this digital therapeutic is effective for schizophrenia?

Research has shown that the Study App, which participants in this trial will use, helps reduce some difficult symptoms of schizophrenia. In earlier studies, people using the app experienced noticeable improvements in symptoms like low motivation and social withdrawal after 16 weeks, when combined with their usual treatments. This suggests the app can be a useful addition to regular medication, helping improve daily life and social skills. The evidence supports that this digital tool can enhance the lives of people with schizophrenia by addressing symptoms that are hard to treat with medication alone. ^{1 6 7 8 9}

Published Research Related to This Trial

In a study involving 38 patients with psychosis, primarily schizophrenia, machine learning models were able to moderately predict how individuals would engage with a smartphone app designed for psychosocial intervention and how their symptoms would change over a month.

The findings indicate that individual responses to smartphone interventions vary widely, and that baseline symptom data can help identify which patients are more likely to benefit from digital treatments, highlighting the importance of personalized approaches in mental health care.

The FREEDoM app aims to enhance shared decision-making and therapeutic relationships between clinicians and patients experiencing first-episode psychosis by providing timely and relevant clinical data, based on input from 11 treatment providers.

Clinicians suggested 31 adaptations to the app's design, with 18 being adopted, focusing on improving content and implementation strategies, which may increase the app's acceptance and integration into clinical practice.

The study found that using a smartphone app for monitoring symptoms and cognitive functions in people with schizophrenia is feasible and acceptable in both India and the United States, suggesting its potential for global use.

Preliminary results indicate that app-based assessments may correlate with traditional clinical and cognitive evaluations, highlighting the app's promise for real-time monitoring, although further research is needed to confirm its long-term effectiveness.

Participants with psychosis engaged well with the Actissist app, responding to 47% of notifications, with the majority of interactions being initiated by the app itself, particularly in areas related to voice-hearing and paranoia.

The study suggests that financial incentives may enhance app engagement, indicating a need for future research to explore non-incentivized engagement in larger groups to better understand the app's effectiveness.

A study analyzing user engagement with a schizophrenia smartphone app found that while 71% of users tried the mood-tracking feature, overall engagement was low, with only a small subset of users contributing the majority of entries.

The findings suggest that clinical involvement may be crucial for increasing engagement with mental health apps, as user interaction followed a power law distribution, indicating that a few users were highly active while most were not.

A review of schizophrenia apps revealed that while there are many research apps (60 identified), only a small number (9) are easily accessible to patients, indicating a gap between research and public availability.

Most marketplace apps (537 found) primarily offer psychoeducation and lack regular updates, with an average of 1121 days since the last update, highlighting the need for more clinically relevant and sustainable app interventions for schizophrenia.

The mobile-assisted cognitive behavioral therapy for negative symptoms (mCBTn) was tested in a preliminary trial with 31 participants suffering from schizophrenia, showing excellent retention (87% at 18 weeks) and significant reductions in defeatist attitudes and experiential negative symptoms.

The results indicate that mCBTn is a feasible and potentially effective intervention for addressing negative symptoms in schizophrenia, supporting the defeatist attitude model and suggesting that technology-enhanced therapies can improve traditional psychosocial treatments.

A study of 83 health-related smartphone apps for conditions like stroke, migraine, depression, Alzheimer's disease, and anxiety found that 69% included intervention components, but only 18% were evidence-based, raising concerns about their efficacy.

While most apps had privacy policies (77%), the complexity of these policies may make it difficult for users to understand how their data is being handled, highlighting a potential safety issue regarding user privacy.
