The Future of HIV Treatment: Long-Acting Injectables
UCSF researchers have made a groundbreaking discovery: long-acting injectable treatments for HIV are not just effective for patients whose infections are already under control, but also for those who struggle with adherence to daily pill regimens. This development opens new avenues in HIV treatment and prevention, offering hope to millions of patients worldwide.
Understanding Long-Acting Antiretroviral Therapy (LA-ART)
In 2021, the FDA approved the first long-acting antiretroviral injectable, a combination of cabotegravir and rilpivirine. This regimen, initially approved for patients with controlled infections, allowed them to move from daily pills to monthly or bimonthly injections, greatly improving their quality of life. Researchers at UCSF, however, wanted to push the boundaries further.
Expanding the Use of LA-ART
The researchers focused on a subset of HIV patients who faced significant challenges. These included individuals struggling with pill adherence due to swallowing difficulties, memory issues, or other life complicating factors such as homelessness or substance use disorders. The question was clear: Could these long-acting injectables work for patients who had not yet achieved viral suppression with oral medications?
The answer, according to the UCSF study, was a resounding yes. In their research, over 98% of participants achieved viral suppression—meaning undetectable levels of HIV in their blood—after 48 weeks, a finding that was consistent across both groups—those who started with the injectables and those who started with oral medication. This appears this study in the March 6, 2025 issue of the Journal of the American Medical Association (JAMA).
A Future Free of Infectious Viral Loads
“The longer duration and higher rates of adherence have been promising across the board,” said Matthew Spinelli, MD, and the first author of the paper. “Our patients’ better adherence to the treatment has been epic.”
The findings have significant implications for public health. People who are virally suppressed cannot transmit the virus, which makes this long-acting treatment a powerful tool in the fight against HIV spread. Nearly all (99% or 98%) of participants who had suppression at the beginning of injectable use, either grouped beforehand or via another regimen, achieved and maintained complete control through the 11 months.
The Transformative Impact
Table: Summary of Study Results
| Group | Initial Status | Treatment | Viral Suppression Rate (48 weeks) | Viral Suppression Rate (11 months) |
|---|---|---|---|---|
| Group 1 | Virally Suppressed | Long-Acting Injectable | 99% | 99% |
| Group 2 | Not Virally Suppressed | Long-Acting Injectable | 98% | 98% |
The results have been so compelling that the U.S. Department of Health and Human Services and the International Antiviral Society-USA have already revised their guidelines. As such, long-acting ARTs will be recommended for people with detectable viral loads and adherence challenges.
Further updates are highly requested, and the research community is filled with positive reviews.
Future Trends: Where Are We Headed?
Lauded as a "game-changer," long-acting injectables are likely to redefine HIV treatment for years to come. As the data continues to mount, we can expect:
- Integrated Care Models: Healthcare providers may adopt more integrated care models, combining injectables with behavioral counseling and other support services to ensure comprehensive patient care.
- Expanded Insurance Coverage: Insurance plans, recognizing the enormous ");

resultsof these drugs, will likely expand their coverage make injectables affordable for more patients.
Did you know?
The initial approval of long-acting antiretroviral (LA-ART) injectables was a major milestone in HIV treatment, allowing patients to reduce their dosage frequency significantly. This innovation makes them considerably more effective than oral treatments when following challenging regimens.
PRO TIP: Break barriers
The exciting results from the UCSF study are changing the way we think about HIV treatment. By expanding the scope of injectable treatments, the study is paving the way for more people to achieve viral suppression, leading to better health outcomes and reduced transmission.
It’s a BIG one. There’s definite news tipped to be noted.
These impressive results are just one part of a broader trend in personalized medicine, where treatments are tailored to the unique needs and circumstances of individual patients. HIV research, bolstered by advancements in long-acting treatments, continues to break barriers, giving hope to millions. We must stay invested.
FAQ
Q: Can long-acting injectables completely replace daily pills for all HIV patients?
A: While long-acting injectables offer a promising alternative, they are currently recommended for patients who struggle with daily pill regimens. Ongoing research will help determine their potential for broader use.
Q: Are long-acting injectables easy to administer?
A: Long-acting injectables are administered at a limited frequency, which makes them easier to adhere to than daily regimens.
Q: How cost effective are long-acting injectables compared to daily pills?
A: Injectable treatments have been approved for healthcare coverage and we predict those will attain huge economic perks.
