MS Treatment Pathway

See where clinical trials fit into your treatment journey

1st Line DMT

Initial disease-modifying therapy after diagnosis

Standard: Interferon beta, Glatiramer acetate, Dimethyl fumarate, or Teriflunomide

2nd Line DMT

After suboptimal response or breakthrough disease activity

Standard: Natalizumab, Fingolimod, Ocrelizumab, or Ofatumumab

Highly Active / Aggressive MS

Rapidly evolving or aggressive disease course

Standard: Alemtuzumab, Ocrelizumab, or Natalizumab

Progressive MS (SPMS / PPMS)

Secondary or primary progressive disease — fewer approved treatments, trials especially important

Standard: Siponimod (SPMS), Ocrelizumab (PPMS), or clinical trial

About MS Subtypes

Relapsing-Remitting (RRMS)

About 85% of MS diagnoses. Characterised by episodes of new or worsening symptoms (relapses) followed by periods of recovery (remission). Most DMTs are approved for this form.

Secondary Progressive (SPMS)

Develops in many people with RRMS over time. Steady progression of disability with or without relapses. Fewer treatment options — clinical trials are especially important.

Primary Progressive (PPMS)

About 10-15% of MS cases. Steady progression from onset without clear relapses. Ocrelizumab is the only approved DMT — trials are critical for new options.
