ABSTRACT
BACKGROUND:
Cytomegalovirus (CMV) infections among hematopoietic stem cell transplant (HSCT) and solid organ transplant (SOT) recipients impose a significant health care resource utilization (HCRU)-related economic burden. Maribavir (MBV), a novel anti-viral therapy (AVT), approved by the United States Food and Drug Administration for post-transplant CMV infections refractory (with/without resistance) to conventional AVTs has demonstrated lower hospital length of stay (LOS) versus investigator-assigned therapy (IAT; valgancilovir, ganciclovir, foscarnet, or cidofovir) in a phase 3 trial (SOLSTICE). This study estimated the HCRU costs of MBV versus IAT.METHODS:
An economic model was developed to estimate HCRU costs for patients treated with MBV or IAT. Mean per-patient-per-year (PPPY) HCRU costs were calculated using (i) annualized mean hospital LOS in SOLSTICE, and (ii) CMV-related direct costs from published literature. Probabilistic sensitivity analysis with Monte-Carlo simulations assessed model robustness.RESULTS:
Of 352 randomized patients receiving MBV (n = 235) or IAT (n = 117) for 8 weeks in SOLSTICE, 40% had HSCT and 60% had SOT. Mean overall PPPY HCRU costs of overall hospital-LOS were $67,205 (95% confidence interval [CI] $33,767, $231,275) versus $145,501 (95% CI $62,064, $589,505) for MBV and IAT groups, respectively. Mean PPPY ICU and non-ICU stay costs were $32,231 (95% CI $5,248, $184,524) versus $45,307 (95% CI $3,957, $481,740) for MBV and IAT groups, and $82,237 (95% CI $40,397, $156,945) MBV versus $228,329 (95% CI $94,442, $517,476) for MBV and IAT groups, respectively. MBV demonstrated cost savings in over 99.99% of simulations.CONCLUSIONS:
This analysis suggests that Mean PPPY HCRU costs were 29%-64% lower with MBV versus other-AVTs.Palavras-chave
