    Association of Initial Disease-Modifying Therapy With Later Conversion to Secondary Progressive Multiple Sclerosis

  • Popis výsledku v původním jazyce

    IMPORTANCE: Within 2 decades of onset, 80% of untreated patients with relapsing-remitting multiple sclerosis (MS) convert to a phase of irreversible disability accrual termed secondary progressiveMS. The association between disease-modifying treatments (DMTs), and this conversion has rarely been studied and never using a validated definition. OBJECTIVE: To determine the association between the use, the type of, and the timing of DMTs with the risk of conversion to secondary progressive MS diagnosed with a validated definition. DESIGN, SETTING, AND PARTICIPANTS: Cohort study with prospective data from 68 neurology centers in 21 countries examining patients with relapsing-remittingMS commencing DMTs (or clinical monitoring) between 1988-2012 with minimum 4 years&apos; follow-up. EXPOSURES: The use, type, and timing of the following DMTs: interferon beta, glatiramer acetate, fingolimod, natalizumab, or alemtuzumab. After propensity-score matching, 1555 patients were included (last follow-up, February 14, 2017). MAIN OUTCOME AND MEASURE: Conversion to objectively defined secondary progressiveMS. RESULTS: Of the 1555 patients, 1123 were female (mean baseline age, 35 years [SD, 10]). Patients initially treated with glatiramer acetate or interferon beta had a lower hazard of conversion to secondary progressiveMS than matched untreated patients (HR, 0.71; 95% CI, 0.61-0.81; P &lt;.001; 5-year absolute risk, 12%[49 of 407] vs 27%[58 of 213]; median follow-up, 7.6 years [IQR, 5.8-9.6]), as did fingolimod (HR, 0.37; 95% CI, 0.22-0.62; P &lt;.001; 5-year absolute risk, 7%[6 of 85] vs 32%[56 of 174]; median follow-up, 4.5 years [IQR, 4.3-5.1]); natalizumab (HR, 0.61; 95% CI, 0.43-0.86; P =.005; 5-year absolute risk, 19% [16 of 82] vs 38%[62 of 164]; median follow-up, 4.9 years [IQR, 4.4-5.8]); and alemtuzumab (HR, 0.52; 95% CI, 0.32-0.85; P =.009; 5-year absolute risk, 10% [4 of 44] vs 25%[23 of 92]; median follow-up, 7.4 years [IQR, 6.0-8.6]). Initial treatment with fingolimod, alemtuzumab, or natalizumab was associated with a lower risk of conversion than initial treatment with glatiramer acetate or interferon beta (HR, 0.66; 95% CI, 0.44-0.99; P =.046); 5-year absolute risk, 7%[16 of 235] vs 12%[46 of 380]; median follow-up, 5.8 years [IQR, 4.7-8.0]). The probability of conversion was lower when glatiramer acetate or interferon beta was started within 5 years of disease onset vs later (HR, 0.77; 95% CI, 0.61-0.98; P =.03; 5-year absolute risk, 3%[4 of 120] vs 6%[2 of 38]; median follow-up, 13.4 years [IQR, 11-18.1]). When glatiramer acetate or interferon beta were escalated to fingolimod, alemtuzumab, or natalizumab within 5 years vs later, the HR was 0.76 (95% CI, 0.66-0.88; P &lt;.001; 5-year absolute risk, 8%[25 of 307] vs 14%[46 of 331], median follow-up, 5.3 years [IQR], 4.6-6.1). CONCLUSIONS AND RELEVANCE: Among patients with relapsing-remittingMS, initial treatment with fingolimod, alemtuzumab, or natalizumab was associated with a lower risk of conversion to secondary progressiveMS vs initial treatment with glatiramer acetate or interferon beta. These findings, considered along with these therapies&apos; risks, may help inform decisions about DMT selection.
