Warnings
Contraindications
Active HBV infection
Cautions
Local and systemic injection-related reactions observed; management for injection-related reactions depends on the type and severity of the reaction
Reduction in immunoglobulins may occur; monitor level of immunoglobulins at the beginning, during, and after discontinuation of treatment until B-cell repletion; consider discontinuing therapy if a patient develops a serious opportunistic infection or recurrent infections if immunoglobulin levels indicate immune compromise
May cause fetal harm based on animal data.
Vaccinations
- May interfere with the effectiveness of inactivated vaccines
- Safety of immunization with live or live-attenuated vaccines following therapy has not been studied
- Administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation for live or live-attenuated vaccines, and whenever possible, at least 2 weeks prior to initiation for inactivated vaccines
- Vaccination with live or live-attenuated vaccines is not recommended during treatment and after discontinuation until B-cell repletion
- Vaccination of infants born to treated mothers H5
- In infants of mothers treated during pregnancy, do not administer live or live-attenuated vaccines before confirming the recovery of B-cell counts
- Depletion of B cells in these infants may increase the risks from live or live-attenuated vaccines
- Consider an assessment of vaccine immune responses, including consultation with a qualified specialist, to determine whether a protective immune response was mounted
- Inactivated vaccines may be administered, as indicated, prior to recovery from B-cell depletion
Infections
- May potentially increase the risk of infections, including serious bacterial, fungal, and new or reactivated viral infections
-
Hepatitis B virus reactivation H5
- There are no reports of HBV reactivation
- HBV reactivation and fatal infections caused by HBV, in some cases resulting in fulminant hepatitis, hepatic failure, and death, has occurred at higher IV doses than the recommended dose in MS but for a shorter duration of treatment
- Monitor and manage following local medical standards to prevent HBV infection or reactivation
-
Progressive multifocal leukoencephalopathy (PML)
- No cases of progressive multifocal leukoencephalopathy (PML) have been reported
- PML resulting in death has occurred at substantially higher IV doses than the recommended dose in MS but for a shorter duration of treatment
- John Cunningham (JC) virus infection resulting in PML has also been observed in patients treated with other anti-CD20 antibodies and other MS therapies
- At first sign or symptom suggestive of PML, withhold and perform an appropriate diagnostic evaluation
- If PML is confirmed, discontinue treatment
Drug interaction overview
-
Immunosuppressants
- When initiating ofatumumab after an immunosuppressive therapy or initiating an immunosuppressive therapy after ofatumumab, consider potential for increased immunosuppressive effects
- Not studied in combination with other MS therapies
- When switching from therapies with immune effects, consider duration and mechanism of action of these therapies because of potential additive immunosuppressive effects when initiating ofatumumab
Pregnancy & Lactation
Pregnancy
There are no adequate data on developmental risk associated with use in pregnant females
May cross the placenta and cause fetal B-cell depletion based on animal studies
Avoid administering live vaccines to neonates and infants exposed to ofatumumab in utero until B-cell recovery occurs
Contraception
- Females of childbearing potential: Use effective contraception during treatment and for 6 months after final dose
Animal data
- Following administration to pregnant monkeys, increased mortality, depletion of B-cell populations, and impaired immune function were observed in the offspring, in the absence of maternal toxicity, at plasma levels substantially higher than that in humans
Lactation
No data available on drug presence in human milk, effects on breastfed infant, or effects on milk production
Human IgG is excreted in human milk, and potential for drug absorption to lead to B-cell depletion in infant is unknown
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Precise mechanism of action in MS is unknown
Recombinant human monoclonal Ig G1 antibody that binds to human CD20, a cell surface antigen expressed on pre-B- and mature B lymphocytes
Binding to B lymphocytes results in antibody-dependent cellular cytolysis and complement-mediated lysis
Absorption
Peak plasma concentration (steady-state): 1.43 mcg/mL
AUC: 483 mcg⋅hr/mL
After SC administration, predominantly absorbed via lymphatic system similarly to other therapeutic monoclonal antibodies
Distribution
Vd: 5.42 L
Metabolism
Expected metabolic pathway is degradation to small peptides and amino acids by ubiquitous proteolytic enzymes
Elimination
Clearance: 0.34 L/day
Half-life: ~16 days
Eliminated by a target-independent route as with other IgG molecules and a target-mediated route that is related to binding to B cells
Administration
SC Preparation
Remove syringe or pen from refrigerator and allow to reach room temperature 15-30 min; do not remove needle cover from prefilled syringe
To avoid foaming, do not shake
Visually inspect for particulate matter and discoloration; do not use if liquid contains visible particles or is cloudy
SC Administration
SC administration only
Administer SC in abdomen, thigh, or outer upper arm; do not inject into moles, scars, stretch marks, or skin that is tender, bruised, red, scaly, or hard
Perform first injection under guidance of healthcare professional
Sensoready pens and syringes are for single dose only; discard after use
See prescribing information for complete administration instructions
Missed dose
- Administer as soon as possible without waiting until next scheduled dose
- Administer subsequent doses at recommended intervals
Storage
Prefilled syringe or Sensoready pen
- Refrigerate at 2-8ºC (36-46ºF); do not freeze
- Keep in original carton to protect from light
- To avoid foaming, do not shake
- May be stored for up to 7 days at room temperature, up to 86ºF (30ºC ) if needed
- Write the date taken out of the refrigerator in space provided on carton
- If stored below 86ºF (30ºC), unused solution may be returned to refrigerator and must be used within next 7 days; if not used within those 7 days, discard the medicine
