Denver, Colorado – A new mobile application designed to support men living with HIV who also apply crystal methamphetamine shows promising results in improving viral suppression, according to data presented at the Conference on Retroviruses and Opportunistic Infections (CROI) 2026. The study, a fully remote randomized controlled trial, found that participants using the app experienced a 58% reduction in the odds of having a detectable viral load after six months compared to a control group.
The findings offer a potential new avenue for addressing the challenges of maintaining treatment adherence among a population facing complex health needs. Men who use stimulants often experience difficulties with consistent antiretroviral therapy (ART), leading to higher rates of viral non-suppression and increased risk of transmission. This innovative approach, leveraging technology and behavioral interventions, aims to bridge that gap and improve health outcomes for this vulnerable group. The research underscores the growing recognition that effective HIV care must address co-occurring substance use.
The START Study and its Innovative Approach
The results were presented by Professor Adam Carrico of Florida International University, a principal investigator on the Supporting Treatment Adherence for Resilience and Thriving (START) study. Professor Sabina Hirshfield from SUNY Downstate Health Sciences University, New York City, and also a principal investigator on the study, provided additional details on the intervention. “we find that the START mHealth application achieved clinically meaningful – albeit short term – reductions in viral load,” Carrico stated. The START study utilized a multi-component approach, integrating technology with evidence-based interventions.
According to Carrico, the success of the app highlights “a need for comprehensive approaches, specifically those that integrate substance use treatment options, like remote contingency management.” Remote contingency management, a behavioral therapy technique, provides rewards for adherence to treatment plans, and was a key component of the START application. The app delivered these incentives remotely, increasing accessibility and convenience for participants.
How the START App Works
The START mHealth application isn’t simply a reminder system. It’s a comprehensive platform designed to address the multifaceted challenges faced by men living with HIV who use stimulants. The app incorporates features such as medication reminders, personalized support messages, and access to remote contingency management. Participants were able to earn rewards for taking their medication as prescribed and engaging in other positive health behaviors. This approach aims to empower individuals to take control of their health and overcome barriers to treatment adherence.
The conference, CROI 2026, held from February 22 to 25, 2026, in Denver, Colorado, showcased a range of groundbreaking research on HIV and related conditions according to the conference program. The event emphasized the importance of incremental progress and expanding treatment options, as noted by John Frater at the start of the conference as reported by AVAC.
Looking Ahead: The Future of Integrated HIV and Substance Use Care
While the initial results are encouraging, researchers emphasize that this is a short-term assessment. Further research is needed to determine the long-term effectiveness of the START application and to identify strategies for sustaining these positive outcomes. The study also highlights the importance of addressing structural barriers to care and ensuring equitable access to treatment for all populations. The National Institutes of Health is currently funding research into remote contingency management for PrEP adherence according to the NIH RePORTER.
The integration of technology and behavioral interventions represents a promising step forward in the fight against HIV, particularly among populations facing complex challenges. As research continues, we can expect to see further innovations in this field, leading to more effective and personalized approaches to HIV care.
