                  • olaparib

                    muromonab CD3 and olaparib both increase pharmacodynamic synergism. Use Caution/Monitor. Coadministration with other other myelosuppressive anticancer agents, including DNA damaging agents, may potentiate and prolongate the myelosuppressive toxicity.

                  • ozanimod

                    ozanimod, muromonab CD3. Either increases effects of the other by immunosuppressive effects; risk of infection. Use Caution/Monitor. Coadministration with immunosuppressive therapies may increase the risk of additive immune effects during therapy and in the weeks following administration. When switching from drugs with prolonged immune effects, consider the half-life and mode of action of these drugs in order to avoid unintended additive immunosuppressive effects.

                  • poliovirus vaccine inactivated

                    muromonab CD3 decreases effects of poliovirus vaccine inactivated by pharmacodynamic antagonism. Modify Therapy/Monitor Closely. Avoid vaccination during chemotherapy or radiation therapy if possible because antibody response might be suboptimal. Patients vaccinated within a 14-day period before starting or during immunosuppressive therapy should be revaccinated =3 months after therapy is discontinued if immune competence has been restored. .

                  • ponesimod

                    ponesimod and muromonab CD3 both increase immunosuppressive effects; risk of infection. Use Caution/Monitor. Caution if coadministered because of additive immunosuppressive effects during such therapy and in the weeks following administration. When switching from drugs with prolonged immune effects, consider the half-life and mode of action of these drugs to avoid unintended additive immunosuppressive effects.

                  • siponimod

                    siponimod and muromonab CD3 both increase immunosuppressive effects; risk of infection. Use Caution/Monitor. Caution if coadministered because of additive immunosuppressive effects during such therapy and in the weeks following administration. When switching from drugs with prolonged immune effects, consider the half-life and mode of action of these drugs to avoid unintended additive immunosuppressive effects.

                  • sipuleucel-T

                    muromonab CD3 decreases effects of sipuleucel-T by pharmacodynamic antagonism. Modify Therapy/Monitor Closely.

                  • zoster vaccine recombinant

                    muromonab CD3 decreases effects of zoster vaccine recombinant by pharmacodynamic antagonism. Use Caution/Monitor. Immunosuppressive therapies may reduce the effectiveness of zoster vaccine recombinant.

                    Warnings

                    Black Box Warnings

                    Only physicians experienced in immunosuppressive therapy and management of solid organ transplant patients should prescribe

                    Anaphylactic or anaphylactoid reactions may occur following administration of any dose or course

                    Serious and occasionally life-threatening systemic, cardiovascular, and CNS reactions (eg, pulmonary edema, especially in patients with volume overload; shock; cardiovascular collapse; cardiac or respiratory arrest; seizures; coma) have been reported

                    Must be managed in a facility equipped and staffed for cardiopulmonary resuscitation

                    Contraindications

                    Hypersensitivity to any murine-derived products

                    Anti-mouse Ab titers ≥ 1:1000

                    Uncontrolled CHF or fluid overload, uncontrolled HTN, H/O seizures, pregnancy, breastfeeding

                    Cautions

                    Pretreatment with methylprednisone recommended

                    Risk of anaphylaxis, cytokine-release syndrome (CRS: flu-like symptoms or shock), severe pulmonary edema; stabilize any cardiovascular pathologies before administration

                    Anaphylaxis usually appears within 10 min of administration; CRS appears 30-60 min later

                    Risk of seizure; monitor neurologic symptoms carefully during first 24 hr following the first few doses

                    Risk of viral infection, lymphoproliferative neoplasia

                    If temp >100°F, lower by antipyretics before next administration

                    Monitor renal function, LFTs, WBCs, platelets; during treatment, monitor muromonab-CD3 levels & T cell clearance daily

                    Pregnancy Category: C

                    Lactation: not known if excreted in breast milk

                    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.

                    Do not give IM

                    Methylprednisolone sodium succinate 1 mg/kg IV given prior to first muromonab-CD3 administration, & IV hydrocortisone sodium succinate 50-100 mg, given 30 min after administration are strongly recommended to decrease the incidence of reaction to the first dose

                    Filter each dose through a low protein-binding 0.22 micron filter before administration

                    Pt temperature should not exceed 37.8°C (100°F) at time of administration

                    Storage
