Drug Interaction | Drug Names |
---|---|
Live Vaccines; Live BCG/Selected Immunosuppressive Agents SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient. MECHANISM OF ACTION: A variety of disease modifying agents suppress the immune system. Immunocompromised patients may be at increased risk for uninhibited replication after administration of live, attenuated vaccines or intravesicular BCG. Immune response to vaccines may be decreased during periods of immunocompromise.(1) CLINICAL EFFECTS: The expected serum antibody response may not be obtained and/or the vaccine may result in illness.(1) After instillation of intravesicular BCG, immunosuppression may interfere with local immune response, or increase the severity of mycobacterial infection following inadvertent systemic exposure.(2) PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies, HIV disease), treatments (e.g. radiation) and drugs may all increase the magnitude of immunodeficiency. PATIENT MANAGEMENT: The Centers for Disease Control(CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live, attenuated vaccines should not be administered to patients who are immunocompromised. The magnitude of immunocompromise and associated risks should be determined by a physician.(1) For patients scheduled to receive chemotherapy, vaccination should ideally precede the initiation of chemotherapy by 14 days. Patients vaccinated while on immunosuppressive therapy or in the 2 weeks prior to starting therapy should be considered unimmunized and should be revaccinated at least 3 months after discontinuation of therapy.(1) Patients who receive anti-B cell therapies should not receive live vaccines for at least 6 months after such therapies due to a prolonged duration of immunosuppression. An exception is the Zoster vaccine, which can be given at least 1 month after receipt of anti-B cell therapies.(1) The US manufacturer of abatacept states live vaccines should not be given during or for up to 3 months after discontinuation of abatacept.(2) The US manufacturer of live BCG for intravesicular treatment of bladder cancer states use is contraindicated in immunosuppressed patients.(3) The US manufacturer of daclizumab states live vaccines are not recommended during and for up to 4 months after discontinuation of treatment.(4) The US manufacturer of guselkumab states that live vaccines should be avoided during treatment with guselkumab.(5) The US manufacturer of inebilizumab-cdon states that live vaccines are not recommended during treatment and after discontinuation until B-cell repletion. Administer all live vaccinations at least 4 weeks prior to initiation of inebilizumab-cdon.(6) The US manufacturer of ocrelizumab states that live vaccines are not recommended during treatment and until B-cell repletion occurs after discontinuation of therapy. Administer all live vaccines at least 4 weeks prior to initiation of ocrelizumab.(7) The US manufacturer of ozanimod states that live vaccines should be avoided during and for up to 3 months after discontinuation of ozanimod.(8) The US manufacturer of siponimod states that live vaccines are not recommended during treatment and for up to 4 weeks after discontinuation of treatment.(9) The US manufacturer of ustekinumab states BCG vaccines should not be given in the year prior to, during, or the year after ustekinumab therapy.(10) The US manufacturer of satralizumab-mwge states that live vaccines are not recommended during treatment and should be administered at least four weeks prior to initiation of satralizumab-mwge.(11) The US manufacturer of ublituximab-xiiy states that live vaccines are not recommended during treatment and until B-cell recovery. Live vaccines should be administered at least 4 weeks prior to initiation of ublituximab-xiiy.(12) The US manufacturer of etrasimod states that live vaccines should be avoided during and for 5 weeks after treatment. Live vaccines should be administered at least 4 weeks prior to initiation of etrasimod.(13) The US manufacturer of emapalumab-lzsg states that live vaccines should not be administered to patients receiving emapalumab-lzsg and for at least 4 weeks after the last dose of emapalumab-lzsg. The safety of immunization with live vaccines during or following emapalumab-lzsg therapy has not been studied.(14) DISCUSSION: Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(1) Patients with a history of leukemia who are in remission and have not received chemotherapy for at least 3 months are not considered to be immunocompromised.(1) |

Available data regarding use of risankizumab in pregnant women are inadequate for establishing a drug-associated risk of major birth defects, miscarriage , or other adverse maternal or fetal outcomes. Monoclonal antibodies can cross the placenta and may cause immunosuppression in the in utero-exposed infant. Consider the risks and benefits of administering live vaccines to infants exposed to risankizumab in utero.
Since the duration of persistence of risankizumab in infant serum after birth is not well established and a specific time frame to delay immunization is unknown, consider delaying administration of live vaccines for a minimum of 5 months after birth due to the half-life of risankizumab. In an enhanced pre- and post-natal developmental study, pregnant cynomolgus monkeys received risankizumab 5 or 50 mg/kg once weekly during the period of organogenesis up to parturition. Fetal/infant loss was observed at the 50 mg/kg dose, which resulted in approximately 5 times the exposure in humans administered the maximum recommended 1200 mg induction dose and 32 times the exposure to the maximum recommended 360 mg maintenance dose.
No malformations and no adverse effects on growth and development, immunologic development, or neurobehavioral development were observed in infant monkeys from birth through 6 months of age. Following delivery, most adult female monkeys and all infant monkeys from the risankizumab-treated groups had measurable serum concentrations of the drug for up to 91 days postpartum. The clinical relevance of these findings is unknown.
A pregnancy exposure registry has been established to monitor outcomes in women who become pregnant while receiving risankizumab-rzaa; patients may be enrolled by calling 877-302-2161or visiting https://glowpregnancyregistry.com.

It is not known whether risankizumab is distributed into human milk, affects milk production, or affects breast-fed infants. Endogenous maternal IgG and monoclonal antibodies are transferred in human milk. Because risankizumab is a large protein molecule, absorption by a breast-fed infant is thought to be unlikely since the drug will probably be destroyed in the infant's GI tract.
The effects of local GI and limited systemic exposure in the breast-fed infant are unknown. Consider the benefits of breast-feeding along with the mother's clinical need for risankizumab and any potential adverse effects on the breast-fed infant from the drug or from the underlying maternal condition.

The manufacturer makes no specific dosage recommendations for geriatric patients. Of the 6862 patients who received risankizumab-rzaa in clinical trials, 664 were >=65 years of age and 71 were >=75 years of age. Clinical trials of patients for each approved indication did not include sufficient numbers of patients >=65 years of age to determine whether geriatric patients respond differently than younger adults. No clinically meaningful differences in the pharmacokinetics of risankizumab-rzaa were observed based on age.
