( 2.1 ) Refer to the Full Prescribing Information for information on preparation and administration. ( 2.2 ) 2.1 Recommended Dosage INMAZEB is a combination of three human monoclonal antibodies co-formulated in a 1:1:1 ratio of atoltivimab, maftivimab, and odesivimab. INMAZEB is available as two different strength presentations, containing either 16.67 mg of each antibody per mL or 33.33 mg of each antibody per mL [see Dosage Forms and Strengths (3) ] .

Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions Including Infusion-Associated Events [see Warnings and Precautions (5.1) ] The most common adverse events (incidence ≥20%) were pyrexia, chills, tachycardia, tachypnea, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Regeneron at 1-844-734-6643 or www.regeneron.com/contact or FDA AT 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates may not reflect the rates observed in practice. Overall, 382 adult and pediatric subjects with Orthoebolavirus zairense infection received INMAZEB in one clinical trial (the PALM trial) and as part of an expanded access program conducted in the Democratic Republic of Congo during a Orthoebolavirus zairense outbreak in 2018-2019. In the PALM trial, the safety of INMAZEB was evaluated in a multi-center, open-label, randomized controlled trial, in which 154 subjects (115 adult subjects and 39 pediatric subjects) received INMAZEB [50 mg of atoltivimab, 50 mg of maftivimab, and 50 mg of odesivimab per kg (3 mL/kg)] intravenously as a single infusion and 168 subjects received an investigational control [see Clinical Studies (14) ] . All subjects received optimized standard of care treatment. During…
Warnings
Important safety information
Hypersensitivity Reactions Including Infusion-Associated Events: Hypersensitivity reactions including infusion-associated events have been reported during and post-infusion with INMAZEB. These may include acute, life-threatening reactions during and after the infusion. Monitor patients and in the case of severe or life-threatening hypersensitivity reactions, discontinue the administration of INMAZEB immediately and administer appropriate emergency care. ( 5.1 ) 5.1 Hypersensitivity Reactions Including Infusion-Associated Events Hypersensitivity reactions including infusion-associated events have been reported during and post-infusion with INMAZEB. These may include acute, life-threatening reactions during and after the infusion. Monitor all patients for signs and symptoms including, but not limited to, hypotension, chills and elevation of fever, during and following INMAZEB infusion. In the case of severe or life-threatening hypersensitivity reactions, discontinue the administration of INMAZEB immediately and administer appropriate emergency care [see Adverse Reactions (6.1) ] . Infusion could not be completed in 1% of subjects who received INMAZEB due to infusion-associated adverse events. The rate of infusion of INMAZEB may be slowed or interrupted if the patient develops any signs of infusion-associated events or other adverse events [see Adverse Reactions (6.1) ] .

Interactions
Interaction with live vaccine indicated for prevention of Orthoebolavirus zairense infection: No vaccine interaction studies have been performed. INMAZEB may reduce the efficacy of the live vaccine. The interval between live vaccination following initiation of INMAZEB therapy should be in accordance with current vaccination guidelines. ( 7.1 ) 7.1 Vaccine Interactions No vaccine-therapeutic interaction studies have been performed in human subjects using INMAZEB. However, because of the potential for INMAZEB to inhibit replication of a live vaccine virus indicated for prevention of Orthoebolavirus zairense infection and possibly reduce the efficacy of the vaccine, avoid the concurrent administration of a live vaccine during treatment with INMAZEB. The interval between live vaccination following initiation of INMAZEB therapy should be in accordance with current vaccination guidelines. The efficacy of INMAZEB among subjects who reported receipt of a recombinant live vaccine prior to their enrollment in the PALM clinical trial was similar to subjects who did not receive a vaccine.
