Slide 1

New Insights into Current MS Treatment NMSS twentieth Annual Research Symposium Robert Shin, MD Maryland Center for MS

Slide 2

Impact of MS Leading non-traumatic reason for incapacity in youthful grown-ups 250,000 to 350,000 influenced in US* National expense of about $10 billion for every year*

Slide 3

MS treatment 1990

Slide 4

MS treatment 1995 Betaseron

Slide 5

MS treatment 2000 Betaseron Avonex Copaxone

Slide 6

MS treatment 2005 Betaseron Avonex Copaxone Rebif Novantrone Tysabri

Slide 9

MS backslide rates - 33% - 29% - 34% - 18% - 66% - 54%

Slide 10

Current MS treatment Long-term adequacy Safety/Tolerability Early treatment Head-to-head correlations

Slide 11

Long-term viability

Slide 12

Long-term adequacy Ideally exhibited by long haul, controlled, near trials Such studies are unreasonable and conceivably untrustworthy

Slide 13

Extension studies PRISMS-4 (Rebif) 7 to 8 years Relapse rate 1.02 (hybrid) versus 0.72 (44mcg) Disability movement deferred by year and a half CHAMPS/CHAMPIONS (Avonex) 5 years (reached out to 10 years) 44% decrease in CDMS at 1.5 years 43% diminishment in CDMS at 5 years

Slide 14

Long-term subsequent Copaxone at 10 years 108 on Copaxone treatment 47 patients pulled back yet were taken after 77 patients lost to catch up 92% as yet strolling without help

Slide 15

Long-term subsequent Copaxone at 26* years 46 took after 28 patients pulled back Average subsequent 10.5 years 26.7% obliged help to walk

Slide 16

Long-term subsequent Betaseron at 16 years Identified 331/372 unique patients 51% (treated) versus 45% (placebo) mobile 95% (treated) versus 83% (placebo) alive

Slide 17

Long-term subsequent Avonex at 8 years 160 patients, no less than 2 years of Avonex Sustained inability at 6 months anticipated handicap at 8 years 67% obliged help versus 24%

Slide 18

Neutralizing antibodies Protein or peptide based treatments may prompt the generation of antibodies When antibodies hinder the biologic impact of the protein/peptide they are alluded to as “neutralizing antibodies” (NAbs)

Slide 19

NAbs to beta interferon Betaseron (beta interferon 1b) 28% to 47% Rebif (beta interferon 1a) 13% to 24% Avonex (beta interferon 1a) 2% to 6%

Slide 20

NAbs to beta interferon Typically show up inside of 3 to year and a half of start of treatment Reduction in adequacy may be postponed Increased backslides Increased MRI ailment weight NAbs may vanish over the long haul?

Slide 21

Conclusions Both beta interferon and glatiramer may be powerful even following 5 to 15 years of treatment Neutralizing antibodies may show up in a minority of patients taking beta interferon

Slide 22

Safety/Tolerability

Slide 23

Safety issues: beta interferon Depression/self-destructive ideation Leukopenia/thrombocytopenia Liver protein rise/hepatic harm Thyroid brokenness Pregnancy classification C

Slide 24

Safety issues: beta interferon CBC and liver board Thyroid capacity tests Monitor for discouragement

Slide 25

Safety issues: glatiramer acetic acid derivation Pregnancy class B

Slide 26

Rebif new plan (RNF) Human serum egg whites free Fetal ox-like sans serum Reduced infusion site responses 30.8% versus 85.8% Increase in influenza like reactions 71% versus 48%

Slide 27

Conclusions Beta interferon and glatiramer are for the most part very much endured

Slide 28

Early treatment

Slide 29

Damage happens ahead of schedule in MS Loss of N-acetylaspartate (NAA) Diffusion tensor imaging (DTI) changes White and dim matter polarization exchange proportion (MTR) variations from the norm Cerebral decay Time is mind!

Slide 30

MS medications Reduce backslide rate Reduce inability Reduce new/dynamic MRI sores Earlier treatment is better!

Slide 31

Clinically Isolated Syndrome (CIS) A solitary scene of neurologic brokenness brought about by a solitary demyelinating injury Optic neuritis Brainstem disorder Spinal line disorder

Slide 32

CIS and MRI Patients with CIS are at expanded danger to create MS later on An anomalous MRI is connected with an incredibly expanded danger to create MS later on

Slide 33

Question Can MS medications advantage patients with CIS?

Slide 34

MS medicines for CIS ETOMS (Early Treatment of MS) CHAMPS (Controlled High-chance Avonex MS Prevention Study) BENEFIT (Betaseron in Newly Emerging MS For Initial Treatment) PreCISe*

Slide 35

MS prescriptions for CIS Randomized controlled trials reliably demonstrate less backslides among CIS patients treated with DMT Avonex and Betaseron now convey FDA signs for treatment of CIS

Slide 36

Conclusions Early treatment of MS is desirable over a postponement in treatment CIS may be the first event of MS medications can be considered in CIS

Slide 37

Head-to-head correlations

Slide 38

Need for direct examination Different studies ought not be contrasted with one another Different consideration/prohibition criteria Different result measures Different populaces

Slide 39

MS backslide rates - 33% - 29% - 34% - 18% - 66% - 54%

Slide 40

Beta interferons Betaseron (beta interferon 1b) Avonex (beta interferon 1a) Rebif (beta interferon 1a)

Slide 41

INCOMIN Beta interferon Betaseron versus Avonex 188 patients took after for a long time Betaseron 42% more inclined to be backslide free 51% (Betaseron) versus 36% (Avonex) Betaseon more prone to be free of MRI action 55% (Betaseron) versus 26% (Avonex)

Slide 42

EVIDENCE Beta interferon 1a 44 mcg tiw (Rebif) versus 30 mcg week by week (Avonex) 677 patients took after for 48 weeks 27% less backslides in Rebif bunch 33% decrease in MRI movement

Slide 43

Interferon versus glatiramer? Rebif versus Copaxone Almost 800 patients randomized Followed for 96 weeks No critical difference*

Slide 44

Interferon versus glatiramer? CombiRX Copaxone + Avonex Copaxone + placebo Avonex + placebo Is Copaxone + Avonex better than either tranquilize alone?

Slide 45

Conclusions Higher measurements, higher frequence beta interferon gives off an impression of being more viable than lower dosage interferon We don\'t know whether beta interferon or glatiramer acetic acid derivation is more powerful

Slide 46

Summary There have been awesome advances in treating MS in the course of recent years Clinical examination has been essential in assisting us with betterring comprehend and refine MS treatment
