Brief summary

To assess safety and tolerability of patients converting from approved Relapsing Multiple Sclerosis (RMS) Disease Modifying Therapies (DMTs) to siponimod.

Detailed description

This is a 6-month, open-label, multi-center, single arm design, including advancing RMS patients, evaluating the overall safety and tolerability profile of converting from oral, injectable or infusion RMS DMTs to oral siponimod.

MeasureTime frameDescription
Number of Participants With at Least One Treatment-emergent Adverse Event (TEAE) Related to Study Drug During the Treatment PeriodFrom first dose of study drug up to 30 days after last dose of study drug (up to 7 months)An Adverse Event (AE) is any untoward medical occurrence in a participant that does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs are defined as the AEs started after the first dose of siponimod to 30 days after the date of the last actual administration, or events present prior to start of treatment but which increased in severity. TEAEs suspected to be related to study drug are reported.

Change From Baseline in Treatment Satisfaction Questionnaire for Medication (TSQM-9)Baseline up to Day 168TSQM-9 measures participant satisfaction with the medication in 3 domains: Effectiveness, convenience, and global satisfaction. The scores were computed by adding items for each domain, i.e., 1 to 3 for effectiveness, 4 to 6 for convenience, and 7 to 9 for global satisfaction. The lowest possible score (1 for each item and 3 for all 3 subscales) was subtracted from the composite score and divided by the greatest possible score range. The greatest range was (7-1) x 3 items = 18 for effectiveness and convenience, and (5-1) x 3 items = 12 for global satisfaction. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100, with higher scores indicating greater satisfaction for that domain. A positive change from baseline indicates improvement.

Recruitment details

Participants were enrolled at study sites in the United States from 14 February 2019 to 06 July 2022.

Pre-assignment details

A total of 342 participants were screened of which 185 participants were enrolled to receive siponimod.

Participants by arm

ArmCount
Siponimod
Participants received titrated doses of siponimod tablets, orally, once daily of 0.25 mg on Day 2, 0.5 mg on Day 3, 0.75 mg on Day 4, 1.25 mg on Day 5, and maintenance dose of siponimod 2.0 mg tablets, orally, once daily from Day 6 up to 6 months. As of protocol amendment 3, participants entering the trial converting from fingolimod started directly with 2 mg dose of siponimod.

Number of Participants With at Least One Treatment-emergent Adverse Event (TEAE) Related to Study Drug During the Treatment Period

An Adverse Event (AE) is any untoward medical occurrence in a participant that does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs are defined as the AEs started after the first dose of siponimod to 30 days after the date of the last actual administration, or events present prior to start of treatment but which increased in severity. TEAEs suspected to be related to study drug are reported.

Time frame: From first dose of study drug up to 30 days after last dose of study drug (up to 7 months)

Population: Safety set included all participants who received at least one dose of study treatment.
