ABSTRACT
BACKGROUND:
Baloxavir marboxil is an oral, single-dose, cap-dependent endonuclease inhibitor that reduces the duration of influenza symptoms and rapidly stops viral shedding. We developed a susceptible, exposed, infected, recovered (SEIR) model to inform a cost-effectiveness model (CEM) of baloxavir versus oseltamivir or no antiviral treatment in the UK. RESEARCH DESIGN ANDMETHODS:
The SEIR model estimated the attack rates among otherwise healthy and high-risk individuals in seasonal and pandemic settings. The CEM assumed that a proportion of infected patients would receive antiviral treatment. Results were reported at the population level (per 10,000 at risk of infection).RESULTS:
The SEIR model estimated greater reductions in infections with baloxavir. In a seasonal setting, baloxavir provided incremental cost-effectiveness ratios (ICERs) of £1884 per quality-adjusted life-year (QALY) gained versus oseltamivir and a dominant cost-effectiveness position versus no antiviral treatment in the total population; ICERs of £2574/QALY versus oseltamivir and £128/QALY versus no antiviral treatment were seen in the high-risk population. Baloxavir was also cost-effective versus oseltamivir or no antiviral treatment and reduced population-level health system occupancy concerns during a pandemic.CONCLUSION:
Baloxavir treatment resulted in the fewest influenza cases and was cost-effective versus oseltamivir or no antiviral treatment from a UK National Health Service perspective.
Baloxavir marboxil ('baloxavir') is a prescription medicine for people who become ill with influenza (or 'the flu') that can reduce how long flu symptoms last and the likelihood of complications from the flu that may require going to the hospital. Baloxavir can also reduce the amount and duration of virus shed by infected individuals thus potentially slow or stop the flu from spreading to healthy people. We studied differences in reducing predicted flu infections between baloxavir and another flu treatment, known as oseltamivir, or no flu treatment at all. Treatment with baloxavir resulted in fewer flu infections in the UK population than oseltamivir or no treatment. We then studied how these differences might affect costs between baloxavir and oseltamivir or no treatment at a population level in the UK. Overall, in the majority of scenarios explored in the model, baloxavir was cost-effective as an antiviral treatment for people with the flu in the UK.
