Background: This study aimed to evaluate the cost-effectiveness of first-line rituximab therapy
in individuals with neuromyelitis optica spectrum disorder (NMOSD) in Korea.
Methods: This study enrolled 42 participants with NMOSD from the clinic of neuroimmunological
diseases of the central nervous system at National Cancer Center. Of these participants,
21 were treated with first-line rituximab therapy (first-line rituximab group) and 21 were
treated with second-line rituximab after switching from azathioprine therapy (second-line
rituximab group). Data on direct medical resource consumption, including hospitalizations
for acute attack management, clinic visits to physicians, examinations, medication use, and
rehabilitation, were collected through a review of medical records and structured interviews of
participants. The mean annual direct medical cost per person for the 5 years after maintenance
immunosuppressive therapy was investigated and compared between the two groups.
Results: The mean total annual direct medical cost per person was 8.9 million won. The mean
annual direct medical cost per person was 1.8 times higher in the second-line rituximab group
than in the first-line rituximab group (10.0 vs. 5.5 million won; p=0.028). The mean annual
direct medical cost per person during azathioprine therapy (14.8 million won) in the second-line
rituximab group was significantly higher than that in the first-line rituximab group (p=0.015).
Conclusions: Even without considering indirect costs, NMOSD has a high economic burden in
Korea. These results suggest that first-line rituximab therapy is more cost-effective than first-line
azathioprine therapy in individuals with NMOSD.
