What are Tier 1 medications?
Interferon beta 1-b, interferion beta-1a, pegylated Inf b-1a, and Copaxone
Indications for Tier 1 medications?
typically considered 1st line therapy for new diagnosis of MS. If patient has severe disease burden, contraindications to the injectables, severe recurrent relapses in a short period, then can start with Tier 2
Mechanism of action of daclizumab/Zinbrya?
modulation of IL-2 mediated activation of lymphocytes
Common Adverse effects of Zinbrya?
URI, pharyngitis, increased ALT, UTI
Labs to follow for Zinbrya and how often?
get baseline ALT/AST/Tbili and check Q mo up to 6 mo after last dose
Mechanism of action of the Inf b-1b and 1a?
anti-inflam: down regulates cytokines, MHC Ags, decrease transmigration of T lymphocytes across the BBB
Side effects of Inf b-1b and 1a?
flu-like sx, leukopenia, elevated liver enzymes, thyroid dysfunction, injection site reaction, depression
Labs to follow for Inf b-1b and 1a?
CBC, LFT q 3 mos during frst yr and then q6mos thereafter; TSH q3-6 mos during 1st year and yearly thereafter, monitor mood changes, site rotation
Mechanism of action of Demethyl fumarate/Tecfidera?
unknown; activates Nrf2 pathway (involved in cellular response to oxidative stress)
Common side effects of Tecfidera?
flushing, abdominal pain, nausea, diarrhea
Warnings of Tecfidera?
lymphopenia
Labs to monitor for Tecfidera?
CBC < 6 mo before starting txt and annually
Mechanism of action of Fingolimod/Gilenya?
binds to immune cells and sequesters them in lymph nodes, reducing availability for cell mediated immune response
-fingolimod crosses BBB –> phosphorylated to form fingolimod-phosphate –> binds to S1P receptors and down regulation of S1P receptors –> reduces release of lymphocytes

Major possible side effects of Gilenya?
bradycardia after 1st dose, infxn, macular edema, decreased PFTs, liver injury, HTN and increase risk of herpes zoster
What do you need to monitor with Gilenya?
screen: WBC, AST/ALT,bili, serum varicella zoster ab testing (in pts withno hx of chicken pox), baseline EKG, ophthalmologic evaluation. Observe brady x 6hrs after 1st dose, ophtho eval after 3-4 mo of txt, PFT if indicated, use contraception during txt and for 2 mo after stopping txt
Efficacy of Gilenya?
it is more effective than injectables; less effective than Tysabri. A good alternative to Tysabri. Per Dr. Eicher, 54% efficacy.
Contraindications to starting Gilenya? (5)
preexisting or recent heart conditions, baseline QTc > 500ms, txt with class Ia or class III antiarrhythmic drugs, TIA, stroke
Efficacy of Tecfidera?
per Dr. Eicher, it has a high fail rate in patients with strong MS
Mechanism of Aubagio
inhibits DNA synthesis in rapidly dividing cells such as lymphocytes. Alternate salvage pathway allows pyrimidine synthesis to continue at reduced rate in resting cells
common side effects of Aubagio?
abnormal liver function, alopecia, diarrhea, influenza, nausea, paresthesias
Black box warnings of aubagio?
black box: elevated LFTs and fetal death/malformations; skin rxn, BP increase, respiratory effects
Pre-txt evaluation for Aubagio? What do you monitor during txt?
pre-txt: eval for infxn, pregnancy, RF, peripheral neuropathy, interstitual pulm disease, HTN, WBC, AST/ALT/tbili. During txt: BP monitoring and AST/ALT
What are Tier 3 medications?
Lemtrada, Novantrone, Tysabri, Ocrevus
Indications for Lemtrada?
pts who have had inadequate response to 2+ therapies
Mechanism of Lemtrada?
binds CD52 (cell surface Ag on T and B lymphocytes, nKC, macrophages) –> ab-dependent cytolysis and complement mediated lysis
Possible side effects of Lemtrada?
infusion rxn in 92% of pts during infusion and up to 24 hours after (3% are severe such as analhylactic shock, angioedema, bronchospasm, hypotension). serious autoimmune condition such as thrombocytopenia and increase risk of malignancy
What to monitor before and during treatment with Lemtrada?
premedicate with corticosteroids prior to 1st three infusions, antiviral agents for herpetic ppx for 2 months or until CD4 count is > 200, check TSH Q3mo and CBC Q month, until 48 mo after last infusion, avoid during active infxn, avoid live viral vaccines
Indications for Novantrone?
SPMS, PRMS, worsening RRMS
Mechanism of action of Novantrone?
inhibits DNA synthesis, reduces lymphocytes, reduces Th1 cytokines
Common side effects of Novantrone?
blue-green urine 24 hours after administration, infections, bone marrow suppression, nausea, hair thinning, bladder infections, mouth sores
Major side effect of Novantrone?
dose dependent cardiac toxicity, AML (esp with cumulative doses > 60mg/m2)
What to monitor while on Novantrone?
baseline LVEF prior to each dose and after txt completed
Mechanism of Tysabri?
binds to alpha4/beta 1 integrin on activated lymphocytes and monocytes; inhibits leukocyte migration across the BBB
Major side effects of Tysabri?
PML, hepatotoxicity including acute liver failure, encephalitis/meningitis with HSV and VZV
What is the general risk of PML when on Tysabri?
1 in 1000
What are risk factors that increase risk of PML in Tysabri recipients to 11 in 1000?
JC ab+, prior txt with immunosuppressant, > 2 years on Tysabri
What to monitor while on Tysabri?
ab testing should be repeated Q6mo with monitoring 6 mo after end of txt
