Introduction: In the CARE-MS I/II (NCT00530348; NCT00548405) trials, alemtuzumab significantly improved clinical/MRI outcomes and quality of life (QoL) measures, including 6-month confirmed disability improvement (CDI) in CARE-MS II, versus SC IFNB-1a over 2 years (y). Efficacy was maintained in 2 consecutive extensions (NCT00930553; NCT02255656 [TOPAZ]).
Aims: To assess EDSS and QoL improvements over 8 y in pooled CARE-MS patients who achieved 6-month CDI.
Methods: Patients received 2 alemtuzumab courses (12mg/day; baseline: 5 days; 12 months later: 3 days) in the core studies, with additional courses (12mg/day; ≥12 months apart) as needed in the extensions. CDI, defined as ≥1-point EDSS decrease confirmed over 6 months, was assessed in eligible patients (baseline EDSS≥2.0). Patients with CDI were stratified by baseline EDSS and assessed for EDSS improvement/stability from baseline through Y8, and 6-month confirmed disability worsening (CDW) post-CDI; improvements from baseline on Functional Assessment of MS (FAMS); Short-Form 36-Item (SF-36) survey mental component summary (MCS), and physical component summary (PCS); and EuroQol 5-dimensions visual analogue scale (EQ-5D VAS) were assessed in patients with CDI.
Results: Of the 375 patients eligible for CDI and with Y8 data, 176 (47%) achieved 6-month CDI. 56% of patients with CDI had improved EDSS from baseline at Y8 versus 4% of those without CDI. Patients with CDI showed improved EDSS at Y8, regardless of baseline EDSS score (EDSS 2.0-2.5: 63% [42/67]; 3.0-3.5: 49% [37/75]; 4.0-4.5: 54% [14/26]; and 5.0-5.5: 75% [6/8]). Across all baseline EDSS levels, ≤14% of patients had 6-month CDW after achieving CDI (2.0-2.5: 7%; 3.0-3.5: 9%; 4.0-4.5: 14%; and 5.0-5.5: 11%). Patients with CDI showed significant improvements from baseline in each y (P< 0.05) through Y8 on FAMS (least squares means, Y1-8: 9.6-12.3), SF-36 (MCS: 2.0-3.1; PCS: 3.3-4.7), and EQ-5D VAS (5.4-9.4). At Y8, most patients with CDI had improved/stable scores on SF-36 (MCS: 75.9%; PCS: 85.6%). Rates of AEs, infections, and thyroid AEs (peaked in Y3) declined through Y8; additional safety will be presented.
Conclusions: Alemtuzumab-treated patients who achieved 6-month CDI showed a high rate of improvement on EDSS at Y8 versus baseline, regardless of baseline EDSS, and had improvements in QoL outcomes which were maintained over 8 y. These results support the use of CDI as a meaningful endpoint for assessing long-term outcomes in RRMS patients.
