Resistenza al farmaco associata a lenacapavir: implicazioni per l'ampliamento della pre-esposizione profilattica HIV a lungo agente.

Although drug resistance could emerge if lenacapavir is initiated during undiagnosed acute infection or if infection occurs during the drug's pharmacokinetic tail, these cases will not compromise the effectiveness of WHO-recommended therapies, as there is no cross-resistance between lenacapavir and other licensed antiretroviral drugs. Lenacapavir pre-exposure prophylaxis (PrEP) is also unlikely to drive population-level lenacapavir resistance given the rarity of breakthrough infections and the reduced replication capacity of most lenacapavir-resistant variants, which most likely reduces their transmission potential. Conversely, the risk of acquiring lenacapavir-resistant HIV-1 while receivin
