Comparing the long-term clinical and economic impact of ofatumumab versus dimethyl fumarate and glatiramer acetate in patients with relapsing multiple sclerosis: A cost-consequence analysis from a societal perspective in Germany

Cost-consequence analysis of early vs. delayed natalizumab use in highly active relapsing-remitting multiple sclerosis: a simulation study

BACKGROUND

Natalizumab (NAT) is an established disease-modifying therapy (DMT) for highly active multiple sclerosis (MS). However, its use involves complex decision-making, often leading to initial use of lower efficacy therapies. Recently, the first biosimilar NAT was approved, enabling competitive pricing. This study assessed the societal implications of initiating NAT in various scenarios through a cost-consequence analysis.

METHODS

A 10-year Markov model based on the Expanded Disability Status Scale (EDSS) was employed, with 11 health states, annual cycles, and half-cycle correction. The cohort had an initial age of 36 years and 70% females. NAT was compared to common initial therapies (glatiramer acetate, teriflunomide, dimethyl fumarate, and fingolimod). Scenarios included continuous use, early (after 1 year), and delayed (5 years) switch to NAT. Baseline characteristics and probabilities for clinical and economic outcomes were derived from clinical trial data, published literature, and other available sources.

RESULTS

Continuous NAT use resulted in the highest time spent on low EDSS levels, fewer relapses, reduced years of life lost due to disability, and a higher employment rate over a 10-year period. Switching to NAT after 1 year yielded outcomes similar to continuous NAT use. Despite higher DMT costs, disease management costs, including indirect costs and non-DMT direct medical costs, were lower in continuous use and early switch to NAT. Late switching resulted in outcomes most comparable to continuous use of the initial DMT.

CONCLUSION

Continuous and early switch to NAT resulted in better clinical outcomes and lower societal economic burden compared to delayed NAT initiation, indicating potential long-term cost savings.

Neutralizing antibody titers over 12 months after SARS-CoV-2 mRNA vaccine booster in patients with relapsing multiple sclerosis continuously treated with ofatumumab

Booster vaccinations against SARS-CoV-2 are recommended 6-12 months after the last dose or infection in elderly and high-risk groups. The present analysis aims to evaluate whether an interval shorter than 12 months is required in multiple sclerosis patients receiving ofatumumab. Neutralizing antibody status over 1 year in patients receiving booster vaccination in the non-interventional, multicenter KYRIOS study under continued ofatumumab treatment was analyzed. Fifteen patients were included. At the time of the first booster vaccination, ten patients were seropositive for neutralizing antibodies, four patients were seronegative, and for one patient, no baseline levels were available. All patients who were seropositive at baseline showed >2-fold increase in neutralizing antibody titers after the first booster and two patients (20%) showed a >10-fold increase. Among seronegative patients, three (75%) had a >10-fold increase in neutralizing antibody titers. Seropositivity was maintained in almost all patients until month 12. One initially seronegative patient had less than 2-fold increase in neutralizing antibody titers after the booster vaccination and can be considered a non-responder. Most patients with continued ofatumumab treatment are able to maintain permanent seropositivity and therefore presumably constant protection against severe courses of COVID-19 if repeated booster vaccinations are applied.

High socioeconomic impact on prescription behavior despite unrestricted access to disease-modifying therapies in people with multiple sclerosis

Background

Economic and health care restraints strongly impact on drug prescription for chronic diseases. We aimed to identify potential factors for prescription behavior in chronic disease. Multiple sclerosis was chosen as a model disease due to its chronic character, incidence, and high socioeconomic impact.

Methods

Germany was used as a model country as the health-care system is devoid of economic and drug availability restraints. German statutory health insurance data were analyzed retrospectively. The impact of number of university hospitals and neurologists as well as the gross domestic product (GDP) as potential factors on prescriptions of platform and high-efficacy disease-modifying therapies (DMTs) was analyzed.

Results

Prescription of platform DMTs increased over time in almost all federal states with varying degree of increase. Univariate regression analysis showed that the prescription volume of platform DMTs positively correlated with the number of university hospitals and neurologists, as well as the GDP per federal state. Stepwise forward regression analysis including all potential factors indicated a statistically significant model for platform DMT (R2 = 0.55; 95%-CI [0.28, 0.82]; p=0.001) revealing GDP as the main contributor. This was confirmed in the independent analysis.

Conclusion

This study illustrates that even without overt drug prescription inequity, access to medication is not evenly distributed and depends on economic strength and regional medical care density.

Early use of high-efficacy therapies in multiple sclerosis in the United States: benefits, barriers, and strategies for encouraging adoption

Multiple sclerosis (MS) is characterized by progressive neuroinflammation and neurodegeneration from disease onset that, if left untreated, can result in the accumulation of irreversible neurological disability. Early intervention with high-efficacy therapies (HETs) is increasingly recognized as the best strategy to delay or mitigate disease progression from the earliest stages of the disease and to prevent long-term neurodegeneration. Although there is growing clinical and real-world evidence supporting early HET intervention, foregoing this strategy in favor of a traditional escalation approach prioritizing lower-efficacy disease-modifying therapies remains a common approach in clinical practice. This review explores potential health care professional- and patient-related barriers to the early use of HETs in patients with MS in the United States. Barriers can include regulatory and reimbursement restrictions; knowledge gaps and long-term safety concerns among health care professionals; and various individual, cultural, and societal factors affecting patients. Potential strategies for overcoming these barriers and encouraging early HET use are proposed.
