The evidence here is Class IV, which is the lowest level of evidence, but the article appeared in Neurology and has a vast number of contributors and collaborators. Also, it's a topic that hasn't often been discussed--what effect DMDs have on people with SPMS.

OBJECTIVE:

To investigate the effect of disease-modifying treatment on short-term disability outcomes in secondary progressive multiple sclerosis (SPMS).

METHODS:

Using MSBase, an international cohort study, we previously validated a highly accurate definition of SPMS. Here, we identified patients in MSBase who were either untreated or treated with a disease-modifying drug when meeting this definition. Propensity score matching was used to select subpopulations with comparable baseline characteristics. Disability outcomes were compared in paired, pairwise-censored analyses adjusted for treatment persistence, visit density, and relapse rates.

RESULTS:

Of the 2,381 included patients, 1,378 patients were matchable (treated n = 689, untreated n = 689). Median pairwise-censored follow-up was 2.1 years (quartiles 1.2-3.8 years).

 No difference in the risk of 6-month sustained disability progression was observed between the groups (HR or hazard ratio 0.9, 95% confidence interval [CI] 0.7-1.1, p = 0.27). We also did not find differences in any of the secondary endpoints: risk of reaching Expanded Disability Status Scale (EDSS) score ≥7 (HR 0.6, 95% CI 0.4-1.1, p = 0.10), sustained disability reduction (HR 1.0, 95% CI 0.8-1.3, p = 0.79), or change in disability burden (area under the EDSS-time curve, β = -0.05, p = 0.09).

Secondary and sensitivity analyses confirmed the results.

CONCLUSIONS:

Our pooled analysis of the currently available disease-modifying agents used after conversion to SPMS suggests that, on average, these therapies have no substantial effect on relapse-unrelated disability outcomes measured by the EDSS up to 4 years.

CLASSIFICATION OF EVIDENCE:

This study provides Class IV evidence that for patients with SPMS, disease-modifying treatment has no beneficial effect on short-term disability progression.
