Background:
Licensed immunotherapies do not slow secondary progressive multiple sclerosis (SPMS) once it has begun. The extent to which SPMS reflects early inflammation - and whether conversion to SPMS might be modified by immunomodulatory disease-modifying therapies (DMTs) during the relapsing-remitting (RR) phase - remains unclear.
Objective:
We examined whether DMTs delay or reduce conversion from RRMS to SPMS using an objective definition of SPMS (Lorscheider 2016, Brain).
Methods:
Patients from MSBase with RRMS treated with a single DMT (injectables (interferons/glatiramer acetate, n=240), fingolimod (n=109), natalizumab (n=93) or alemtuzumab (n=44) with at least 4 years' on-treatment follow-up were each propensity matched to 1) untreated patients with RRMS from a historical cohort (n=622, mean follow-up 9.2 years); then 2) different DMT groups. Patients were matched on gender plus baseline age, annualised-relapse rate, EDSS score and disease duration.
Weighted conditional proportional hazards models adjusted for EDSS frequency with pair-wise censoring compared the proportions of each group free from conversion to SPMS. Lower efficacy drug groups may have been biased towards milder disease through excluding patients with multiple DMTs (such as treatment escalators). We therefore limited the injectables group to patients followed-up before higher-efficacy drugs (for treatment escalation) became available in 2006.
Results:
Injectables (HR 0.31, p< 0.001, median censored on-treatment follow-up 7.9 years), fingolimod (HR 0.23, p< 0.001, follow-up 4.6 years), natalizumab (HR 0.50, p=0.001, follow-up 4.9 years) and alemtuzumab (HR 0.60, p=0.01, follow-up 7.2 years) reduced the hazard of conversion to SPMS compared to different groups of matched untreated patients in a series of pairwise analyses.
When matching between the treated cohorts there was no significant difference in conversion to SPMS between alemtuzumab and natalizumab patients (p=0.2). Alemtuzumab and natalizumab were therefore combined as 'high-efficacy therapies' (n=118) and matched and compared to the injectables group (n=236). High-efficacy therapies conferred greater protection against conversion to SPMS than injectables (HR 0.65, p=0.038, follow-up 5.7 years).
Conclusion:
SPMS is - at least partially - a consequence of early inflammation. The risk of conversion from RRMS to SPMS is modifiable over 5 years with existing DMTs, more so with high-efficacy therapies, alemtuzumab and natalizumab.
