Clinicians frequently seek to simplify antiretroviral therapy (ART) for patients living with HIV. The B/F/TAF switch HIV strategy offers a potent, single-tablet option for those currently managed on NNRTI-based regimens. Recently, the DRIVE-SWITCH study evaluated the effectiveness of this transition in virologically suppressed individuals. This retrospective analysis provides valuable real-world evidence for modern HIV management, especially for patients transitioning from rilpivirine (RPV).
The study analyzed 250 people with HIV (PWH) who were already virologically suppressed on NNRTI triple therapy. Most participants transitioned from rilpivirine-based regimens. Because maintaining suppression is critical, the researchers monitored outcomes over 12 months. Results showed that 95.2% of patients with available data maintained viral suppression. Furthermore, the mean CD4+ T-cell count increased by 52 cells/mm³ during the follow-up period. Consequently, the switch appears both effective and immunologically beneficial for clinical practice.
Adverse events leading to treatment discontinuation were remarkably rare in this cohort. Only 1.6% of participants stopped the regimen due to issues such as insomnia, mood disorders, or epigastric pain. Additionally, no new resistance mutations emerged during the study period. This is significant because a high genetic barrier to resistance is a hallmark of second-generation integrase inhibitors. Therefore, this single-tablet regimen serves as a durable alternative for long-term maintenance in suppressed patients.
Switching to B/F/TAF simplifies treatment by providing a single-tablet regimen. It offers a high genetic barrier to resistance and typically improves tolerability compared to older NNRTI regimens.
Approximately 95.2% of patients with available 12-month follow-up data maintained an HIV-RNA level of less than 50 copies/mL after switching.
Yes, the study specifically included many patients switching from rilpivirine-based regimens and found high efficacy with very few treatment discontinuations.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
