Ensitrelvir for Viral Persistence and Inflammation in People Experiencing Long COVID

Running, not enrolling · Phase 2 · Has a placebo group

Conditions studied: Long COVID, Post Acute Sequelae of COVID-19, Post-Acute COVID-19

In brief

Persistent viral infection with viral reservoirs and detection of circulating spike protein after the initial acute illness is one potential pathogenic mechanism for Long COVID. This mechanism may be susceptible to antiviral therapy that blocks viral replication, which has the potential to alleviate long COVID symptoms. This trial will study the safety and efficacy of Ensitrelvir (S-217622), an antiviral, to treat individuals with Long COVID in an adult population.
