Cost-effectiveness of cladribine tablets and dimethyl fumarate in the treatment of relapsing remitting multiple sclerosis in Spain.

Aim: To analyze the cost-effectiveness of treatment of relapsing remitting multiple sclerosis (RRMS) with cladribine tablets (CladT) and dimethyl fumarate (DMF) from the perspective of the Spanish National Health System (NHS).

Methods

A probabilistic Markov model (second-order Monte Carlo simulation) with a 10-year time horizon and annual Markov cycles was performed.

Results

CladT was the dominant treatment, with lower costs (-74,741 € [95% CI: -67,247; -85,661 €]) and greater effectiveness (0.1920 [95% CI: -0.1659; 0.2173] QALY) per patient, compared with DMF. CladT had a 95.1% probability of being cost-effective and a 94.1% chance of being dominant compared with DMF.

Conclusion

CladT is the dominant treatment (lower costs, with more QALYs) compared with DMF in the treatment of RRMS in Spain.
