Study of Evobrutinib in Participants With RMS (evolutionRMS 2)

Phase 3

Terminated

Conditions: Relapsing Multiple Sclerosis

Interventions: Drug: Teriflunomide
Drug: Evobrutinib

Registration Number: NCT04338061

Lead Sponsor: Merck Healthcare KGaA, Darmstadt, Germany, an affiliate of Merck KGaA, Darmstadt, Germany

Brief Summary: The study is to evaluate the efficacy and safety of evobrutinib administered orally twice daily versus Teriflunomide (Aubagio®), administered orally once daily in participants with Relapsing Multiple Sclerosis (RMS). Participants who complete the double-blind treatment period (DBTP) and double-blind extension period (DBEP) prior to approval of a separate long-term follow-up study in their country will get an option for evobrutinib treatment continuation through a 96-week open-label extension (OLE) period.

Primary Outcome Measures

Name	Time	Method
Double Blind Treatment Period (DBTP) and Double Blind Extension (DBE) Period: Annualized Relapse Rate (ARR)	Baseline up to 170 weeks	The qualifying relapse is the occurrence of new or worsening neurological symptoms attributable to Multiple Sclerosis (MS) (for more than \[\>\] 24 hours, no fever, infection, injury, adverse events (AEs), and preceded by a stable or improving neurological state for more than or equal to \[\>=\] 30 days).

Secondary Outcome Measures

Name	Time	Method
DBTP and DBE Period: Percentage of Participants Without 12-Week Confirmed Disability Progression (CDP) as Measured by Expanded Disability Status Scale (EDSS)	Week 96 and Week 156 (combined DBTP and DBE periods)	Disability progression was defined as increase in EDSS of greater than or equal to \[\>=\] 1 point from baseline EDSS score, if EDSS score at baseline is 5.0 or less and an increase of \>=0.5 point, if the baseline score is 5.5. Disability progression is considered sustained for 12 weeks when the initial increase in the EDSS is confirmed at a regularly scheduled visit at least 12 weeks after the initial documentation of neurological worsening. The total EDSS score ranges from 0 (normal) to 10 (death due to multiple sclerosis). Kaplan-Meier method was used to estimate the percentage of participants without 12-week CDP.
DBTP and DBE Period: Percentage of Participants Without 24-Week Confirmed Disability Progression (CDP) as Measured by Expanded Disability Status Scale (EDSS)	Week 96 and Week 156 (combined DBTP and DBE periods)	Disability progression was defined as increase in EDSS of greater than or equal to \[\>=\] 1 point from baseline EDSS score, if EDSS score at baseline is 5.0 or less and an increase of \>=0.5 point, if the baseline score is 5.5. Disability progression is considered sustained for 24 weeks when the initial increase in the EDSS is confirmed at a regularly scheduled visit at least 24 weeks after the initial documentation of neurological worsening. The total EDSS score ranges from 0 (normal) to 10 (death due to multiple sclerosis). Kaplan-Meier method was used to estimate the percentage of participants without 24-week CDP.
DBTP and DBE Period: Percentage of Participants With 24-Week Confirmed Disability Improvement (CDI) as Measured by Expanded Disability Status Scale (EDSS)	Week 96 and Week 156 (combined DBTP and DBE periods)	Disability improvement was defined as a reduction of 1 point from Baseline EDSS score when the Baseline score is \>= 2 and less than or equal to \[\<=\] 6 and a reduction of 0.5 point from Baseline EDSS score when the Baseline score is \>= 6.5 and \<= 9.5. Disability improvement is considered sustained when the initial reduction in the EDSS score is confirmed at a regularly scheduled visit at least 24 weeks after the initial reduction. The total EDSS score ranges from 0 (normal) to 10 (death due to multiple sclerosis). Kaplan-Meier method was used to estimate the percentage of participants with 12-week CDI.

PROMIS Fatigue (MS) 8a assesses level of fatigue and its interference on daily activities. Results are reported as a T-score. In the general population, T-scores have a mean of 50, standard deviation of 10, and range from 33 to 85. Higher T-scores represent higher fatigue.
