4 Progressive MS What is progressive MS?

5 Progressive MS: definitions Progression process of moving gradually towards a more advanced state Progressive disease disease that is spreading or whose course is worsening Stedman's Medical Dictionary

7 Progressive MS: definitions Schumacher 1965 slow or step-wise progression of signs and symptoms, over a period of at least 6 months Poser 1983 steady progression has taken place for at least 6 months, and evidence for [other CNS] involvement should not have been present at the time paraparesis first appeared McDonald 2001 insidious neurological progression suggestive of MS dissemination in space (MRI +/- VEP) continued progression for 1 year positive CSF Schumacher et al, Ann NY Acad Sci 1965 Poser et al, Ann Neurol 1983 McDonald et al, Ann Neurol 2001

8 Progressive MS: definitions McDonald 2005 insidious neurological progression suggestive of MS 1 year of disease progression two of the following + brain MRI, + spinal cord MRI, + CSF McDonald 2010 insidious neurological progression suggestive of MS same as 2005, with less strict MRI criteria McDonald year of disability progression independent of clinical relapse two of the following (same as 2010) Polman et al, Ann Neurol 2005 Polman et al, Ann Neurol 2011 Thompson et al, Lancet Neurol 2018

9 Progressive MS: definitions Progressive disease course insidious accumulation of neurologic deficits independent of relapses and MRI activity Progression of disability insidious accumulation independent of relapses stepwise accumulation from relapses Weinshenker et al, Brain 1989; Trojano et al, JNNP 1995 Kantarci et al, Neurology 1998; Confavreux et al, Brain 2006 Tutuncu et al, MSJ 2012

21 Progressive MS: impact of relapses Time to EDSS 6 after progressive MS onset Pre-progression relapses SPMS SAPMS PPMS = 50% in 4 years = 50% in 7 years = 50% in 10 years Paz Soldan et al, Neurology 2015

23 Progressive MS: impact of relapses Time to EDSS 6 after progressive MS onset Pre-progression relapses SPMS SAPMS PPMS = 50% in 4 years = 50% in 7 years = 50% in 10 years Post-progression relapses 2 yrs. shorter with ongoing relapses Paz Soldan et al, Neurology 2015

24 Progressive MS: impact of relapses Presence of ongoing relapses after progressive MS onset SPMS = 29.5% SAPMS = 10.7% PPMS = 3.1% Timing of ongoing relapses after progressive MS onset 91.6% within 5 years 95.2% before age 55 Paz Soldan et al, Neurology 2015
