Long-term Impact of Early MS Treatment with Interferon Beta-1b (IFNB-1b): Clinical, MRI, Employment, and Patient-Reported Outcomes (PROs) at the 11-Year Follow-up of BENEFIT (BENEFIT 11) (P7.012)

Abstract : OBJECTIVE:To study long-term outcomes in patients treated with IFNB-1b after clinically isolated syndrome (CIS). BACKGROUND:In BENEFIT, patients with CIS were randomized to IFNB-1b or placebo (PL) treatment. After the second clinical event or after 2 years, all patients were treated with IFNB-1b. Mean delay of IFNB-1b in PL was 1.33 years. Comprehensive clinical, MRI, and PROs at 11 years post-randomization are reported. DESIGN/METHODS:All originally randomized patients were asked to undergo clinical, MRI, laboratory, and PRO assessments 11 years after randomization. RESULTS:281 patients were identified (60[percnt] of originally randomized, 72.6[percnt] of eligible patients at participating sites); 278 enrolled. Baseline characteristics were similar to the original BENEFIT population. At Year 11, patients randomized to IFNB-1b still had lower overall annualized relapse rate (p=0.0018) and longer time to first relapse (p=0.0005) and clinically definite MS (p=0.0012). Median EDSS score was 2.0 (change from baseline 0.5) in both groups. PASAT scores remained high (overall median 56 [IQR 10]). Of the 81.3[percnt] working at CIS start, 73.4[percnt] were still employed (64.4[percnt] fulltime). 12.2[percnt] retired early or were on long-term disability (2.9[percnt] at baseline). 64.0[percnt] did not report any sick leave during the past 12 months. Health-related quality of life remained stable (median [IQR] change from baseline EQ-5D: 0.000 [0.209], FAMS TOI: -7.54 [27.17]. Median (IQR) fatigue (FSMC) score: 45.00 (40.00), 46[percnt] of patients without fatigue (cut-off score\textless43), median (IQR) depression (CES-D) score: 9.00 (15.00). MRI findings were similar across groups: 86.4[percnt] had no gadolinium-enhancing lesions; median (IQR) number of new T2 lesions since 5-year MRI: 2.0 (6.0), T2 volume: 1760.0mm³ (3963.0mm³), cortical lesions: 2.0 (5.0), brain volume 1519.0cm³ (152.0mm³), mean cortical thickness 2.64mm³ (0.56mm³). CONCLUSIONS:Results from BENEFIT11 support a long-term impact of early treatment with IFNB-1b on clinical measures, including cognition and fatigue, and health economic and MRI outcomes.
