Lessons for long-acting lenacapavir: catalysing equitable PrEP access in low-income and middle-income countries.

Despite substantial advances in biomedical HIV prevention, including long-acting injectable pre-exposure prophylaxis (PrEP) options such as cabotegravir, barriers to widespread adoption and scale-up persist in low-income and middle-income countries. Long-acting injectable lenacapavir is a potentially transformative HIV prevention tool, providing an unprecedented opportunity to accelerate progress. However, the global HIV response is under threat like never before, with drastic funding cuts undermining the gains of the past 25 years. The challenges of introducing and scaling up long-acting lenacapavir and other PrEP innovations are numerous. Without deliberate policy, programmatic, and financing interventions, new prevention technologies risk following slow adoption patterns of previous innovations, weakening a needed transformation of the HIV response. Drawing on lessons from the scale-up of antiretroviral therapy, and experience with previous biomedical prevention tools, a new ten-point framework should be adopted to accelerate individual and epidemiological impact-even at this time of extraordinary uncertainty.
