Evolving Oral PrEP Guidance for Ciswomen: What do we know, and what will it take?
Scientific consensus is evolving, but PrEP clinical equity remains unachieved. Recent data has challenged the “conventional wisdom” surrounding vaginal PrEP tissue concentrations, proving oral PrEP (TDF/FTC, TAF/FTC) is significantly...

PxWire Volume 16, Issue 3
This issue of PxWire showcases updates presented at the AIDS 2026 conference in Rio de Janeiro, Brazil. As the field continues to grapple with the impact of PEPFAR funding cuts on HIV services, amfAR shared their latest analysis from the PEPFAR Pulse Study. AVAC’s latest infographic unpacks the current status of generic licensing agreements for long-acting PrEP products. Recent trials on long-acting treatment and broadly neutralizing antibodies (bNAbs) for prevention were also shared at the conference. A new weekly pill for HIV treatment demonstrated non-inferiority, while a combination of two bNAbs did not provide protection from HIV. Both results provided important insights and implications for the current status of the HIV prevention and treatment pipelines.

Percentage Change in PEPFAR Prevention Expenditures, FY24 to FY25
This infographic, with data featured in amfAR’s PEPFAR Pulse study, examines the percentage change in PEPFAR prevention expenditures from FY24 to FY25. Significant challenges persist in the wake of cuts to PEPFAR programs, as the ripple effects continue to be felt across the field and organizations grapple with how to maintain services with fewer resources.

ISL/LEN Phase 3 Development Program
At AIDS 2026, Merck and Gilead presented detailed results from the Phase 3 ISLEND trials, showing that an investigational weekly oral single-tablet treatment regimen combining islatravir (ISL) from Merck/MSD and lenacapavir (LEN) from Gilead sustained viral suppression as effectively as daily oral antiretroviral therapy (ART) at week 48; the studies will continue to week 96. This infographic features data from Gilead’s AIDS 2026 presentations on ISLEND-1 and ISLEND-2 trials.

ARV-Based and Multipurpose Prevention Technology R&D Pipeline
The pipeline of non-vaccine HIV prevention products includes oral pills, vaginal rings, vaginal and rectal gels, vaginal films, long-acting injectable antiretrovirals and more. Also pictured are the range of MPTs in development that aim to reduce the risk of HIV and STIs and/or provide effective contraception for women.

Years Ahead in HIV Prevention Research: Time to Market
This timeline shows the potential time points when the next-generation of HIV prevention options might find their way into new programs.

An “Innovation Pile-Up” in Next-Generation LA-PrEP is Possible
The HIV prevention market is headed toward a period of significant opportunity—and possible congestion—as a slate of new products are on track for continued development and potential introduction to the market in 2027 and 2028. Markets and policies must be built to support the products in the market already, so that new options can be rapidly deployed and deliver impact. Otherwise, the field will squander time and money, with epidemic control slipping further out of reach.

EXPrESSIVE Phase III Program Countries of Alimatravir
Seventeen countries are hosting sites for the Phase III efficacy trials of a monthly PrEP pill, called MK-8527, now known as alimatravir, being developed by Merck (also known as MSD outside of the US and Canada). Merck announced the launch of the Phase III trials at IAS 2025 in Kigali. Alimatravir (AMI) was found to be safe and well-tolerated in Phase II clinical trials.
