Ocrelizumab: Post-Marketing Updates

Post Test: Question #1

• KS is a 52 year old white female diagnosed with MS 20 years ago.

At the time of diagnosis her MRI showed multiple Gd+ enhancing

and non-enhancing lesions in the infratentorial and along her

spinal cord and her lumbar puncture was (+) for oligoclonal bands.

KS continues to experiences relapses at least yearly and her most

recent MRI demonstrated new Gd+ enhancing lesions in the

juxtacortical and periventricular regions of her brain. She does not

experience worsening of disease outside of relapses.

1. How would you classify KS’s disease course?

a) Secondary-progressive MS- active, not progressing

b) Relapsing-remitting MS- active

c) Clinically Isolated Syndrome

d) Primary-progressive MS- not active, progressing


• KS has now failed the oral option you selected for her

previously (totaling 4 failed therapies). Labs were completed

to assist in further therapy selection.

2. Based on clinical trial data and

recent FDA post-marketing reports,

which of the following therapies would

you avoid in KS?

a) Ocrelizumab

b) Daclizumab

Na 141 mEq/L

K 3.6 mEq/L

Cl 106 mEq/L

CO2 24 mEq/L

SCr 0.74 mg/dL

BUN 14 mg/dL

GLU 88 mg/dL

Ca 9.5 mg/dL

AST 130 U/L

ALT 154 U/L

Vit D 18 ng/mL


3. To date no reports of progressive multifocal

leukoencephalopathy (PML) have been

reported with either daclizumab or

ocrelizumab.

a) True

b) False

Take Home Points

• The exact cause of MS is still unknown, but multiple

risk factors have been identified and several new

therapies have been developed within the last few

years, specifically daclizumab and ocrelizumab.

• The choice of therapy is based upon many factors,

including patient and provider preference, disease

course and severity, patient specific factors, and

medication adverse effects.
