NCT05826028

Who might be able to join this trial:

• You are an adult who has been diagnosed with secondary progressive multiple sclerosis (a form of MS that gradually gets worse over time), as confirmed by your doctor.
• Your level of physical disability falls within a specific range on a standard MS disability scale (meaning you have some disability but are still able to walk, at least with assistance).
• You are receiving or will receive the medication Mayzent (siponimod) through an approved patient access program or government subsidy scheme, and you meet the required criteria for that program.

Who may not be able to join:

• You cannot take the medication Mayzent due to a medical reason that makes it unsafe for you (confirm with trial site).
• You have been diagnosed with a different form of MS — specifically, either a first single episode (clinically isolated syndrome) or primary progressive MS (the type that worsens steadily from the very beginning).

Important: Always verify eligibility with the trial site directly before applying.
