No Evidence of Disease Activity (NEDA-3) in the Phase 3 EVOLVE-MS-1 Study

Study Design1:

  • EVOLVE-MS-1 was an open-label, single-arm, 96-week, phase 3 study to evaluate DRF safety, tolerability, and exploratory efficacy endpoints in adults with RRMS:
    • Patients entered the study either after completing EVOLVE-MS-2, a randomized, 5-week, double-blind, head-to-head, phase 3 study of DRF and DMF, or as newly enrolled in the DRF clinical development program
    • Overall, 1057 patients were included in EVOLVE-MS-1, of whom 239 (22.6%) had received DRF in EVOLVE-MS-2 and then rolled over into EVOLVE-MS-1 (“prior DRF” group); 225 (21.3%) had received DMF in EVOLVE-MS-2 and rolled over into EVOLVE-MS-1 (“prior DMF” group); and 593 (56.1%) were newly enrolled (“de novo” group)

Re-Baselining1:

  • This analysis assessed outcomes in EVOLVE-MS-1 based on patients who had rolled over from receiving DRF or DMF in EVOLVE-MS-2 (“prior DRF” and “prior DMF” groups, respectively), or who had newly enrolled in EVOLVE-MS-1 (“de novo” group)
  • Patients who rolled over from EVOLVE-MS-2 had a treatment duration of ≥ 5 weeks on DRF or DMF in EVOLVE-MS-2 and rolled over into EVOLVE-MS-1 within 7 days of treatment completion
  • Magnetic resonance imaging was performed within 7 days of the start of EVOLVE-MS-1
    • Patients who received DRF in both studies were on study medication for up to 7 weeks before efficacy outcomes were assessed and were thus re-baselined after ~7 weeks

Assessments1:

  • MRI scans were performed at baseline before each study start (~7 weeks apart) and at Weeks 48 and 96 in EVOLVE-MS-1. Relapses and disability were assessed in EVOLVE-MS-1
  • NEDA-3 was defined as having no relapse, no 24-week confirmed disability progression (CDP), and no MRI activity (ie, no new or newly enlarging T2 lesions and no new gadolinium-enhancing lesions)
  • Proportions of patients who were free from CDP, were relapse free, and had NEDA-3 were estimated using the Kaplan–Meier product limit method
  • Analyses were performed using SAS 9.4

Safety outcomes reported for the prior DRF, prior DMF, and de novo patient groups included AEs, AEs leading to discontinuation, and serious AEs.

NEDA-3 Study Graphic*

NEDA-3 was defined as having no relapse, no 24-week confirmed disability progression (CDP), and no MRI activity (ie, no new or newly enlarging T2 lesions and no new gadolinium-enhancing lesions)1

Limitations1:

  • Due to the study design, disease activity within the first 7 weeks before re-baselining could not be assessed in these patients
  • This was a post hoc analysis and NEDA-3 was an exploratory efficacy endpoint of the EVOLVE-MS-1 study. The clinical and radiological efficacy endpoints that comprise NEDA-3 have been studied individually in DMF and VUMERITY, but not with NEDA-3 named as a specific primary or secondary trial endpoint

More than half of patients on VUMERITY achieved No Evidence of Disease Activity
(NEDA-3) after re-baselining1

NEDA-3 Outcomes After Re-baselining in VUMERITY Rollover Patients

Week 96 prior DRF group

  • Corresponding estimates at week 96 were 48.2% in the prior DMF group, and 36.5% in the de novo group
  • Compared with the de novo group, the proportion of patients achieving NEDA over the study period was higher in the prior DRF group and the prior DMF group

*NEDA-3 was defined as having no relapse, no 24-week CDP, no new or newly enlarging T2 lesions, and no new Gd+ lesions.

Patients across all groups experienced adverse events; most were mild to moderate1

Adverse events occurred in 212 (88.7%) patients in the prior DRF group, 207 (92.0%) patients in the prior DMF group, and 519 (87.5%) patients in the de novo group; most were mild to moderate in severity

  • The most common AEs in the prior DRF and prior DMF groups were MS relapse (20.1% and 20.0%, respectively), upper respiratory tract infection (17.6% and 15.6%), lymphopenia (14.6% and 16.9%), and flushing (13.8% and 12.9%); in the de novo group, the most common AEs were flushing (38.1%), MS relapse (19.1%), and nasopharyngitis (14.5%)
  • Lymphopenia was reported in 51 (8.6%) patients in the de novo group
  • Adverse events led to discontinuation of DRF in 23 (9.6%) patients in the prior DRF group, 13 (5.8%) patients in the prior DMF group, and 49 (8.3%) patients in the de novo group
  • Serious AEs occurred in 12.1% (n=29) of patients in the prior DRF group, 11.1% (n=25) of patients in the prior DMF group, and 11.6% (n=69) of patients in the de novo group
  • There were 71 (29.7%) discontinuations in the prior DRF group, 61 (27.1%) in the prior DMF group, and 125 (21.1%) in the de novo group
