Overview
Atoltivimab, maftivimab, and odesivimab-ebgn is a combination of Orthoebolavirus zairense glycoprotein (GP) directed recombinant human IgG1 human monoclonal antibodies of similar structure. The human monoclonal antibodies, atoltivimab, maftivimab, and odesivimab are produced by recombinant DNA technology in Chinese hamster ovary (CHO) cell suspension culture and have an approximate molecular weight of 145 kDa, 146 kDa and 144 kDa, respectively. INMAZEB (atoltivimab, maftivimab, and odesivimab-ebgn) injection for intravenous use is a sterile, preservative-free, clear to slightly opalescent, colorless to pale yellow solution, that is free from visible particulates. INMAZEB injection is supplied as two strength presentations: 16.67 mg/16.67 mg/16.67 mg per mL: Each vial contains 241.7 mg of atoltivimab, 241.7 mg of maftivimab, and 241.7 mg of odesivimab in 14.5 mL. Each mL contains 16.67 mg of atoltivimab, 16.67 mg of maftivimab, 16.67 mg of odesivimab, and L-histidine (0.74 mg), L-histidine monohydrochloride monohydrate (1.09 mg), polysorbate 80 (1 mg), sucrose (100 mg), and Water for Injection, USP with a pH of 6.0. 33.33 mg/33.33 mg/33.33 mg per mL: Each vial contains 483.3 mg of atoltivimab, 483.3 mg of maftivimab, and 483.3 mg of odesivimab in 14.5 mL. Each mL contains 33.33 mg of atoltivimab, 33.33 mg of maftivimab, 33.33 mg of odesivimab, and L-histidine (0.74 mg),…
How to use
The recommended dosage of INMAZEB is 50 mg of atoltivimab, 50 mg of maftivimab, and 50 mg of odesivimab per kg diluted and administered as a single intravenous infusion. ( 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) ] . The recommended dosage of INMAZEB is 50 mg of atoltivimab, 50 mg of maftivimab, and 50 mg of odesivimab per kg diluted and administered as a single intravenous infusion as shown in Table 1 [see Dosage and Administration (2.2) ] . 2.2 Preparation and Administration INMAZEB must be prepared and administered under the supervision of a healthcare provider. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. INMAZEB should be clear to slightly opalescent, colorless to pale yellow solution that is free from visible particulates. Discard the vial if the solution is cloudy, discolored or contains particulate matter. Preparation for Intravenous Infusion The…
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…

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.
