What is Ebanga?

From the FDA label:Ansuvimab-zykl is an Orthoebolavirus zairense (EBOV) glycoprotein 1 (GP1)-directed recombinant, human IgG1 monoclonal antibody. Ansuvimab-zykl is produced in Chinese Hamster Ovary (CHO) cells by recombinant DNA technology and has an approximate molecular weight of 147 kDa. EBANGA (ansuvimab-zykl) for injection is a sterile, preservative-free, off-white to white lyophilized powder in a single-dose vial for IV use after reconstitution and dilution. Each single-dose vial delivers 400 mg of ansuvimab-zykl, and L-histidine (12.4 mg), L-histidine HCl (16.8 mg), polysorbate 80 (1.6 mg), and sucrose (657 mg). After reconstitution with 7.7 mL of Sterile Water for Injection, USP, each vial delivers 8 mL of a clear and colorless to slightly yellow solution containing 50 mg/mL of ansuvimab-zykl, with an approximate pH of 6.

How to use

Ebanga is sold in more than one form (Injectable and Kit), and each is dosed differently. The instructions below come from the FDA label for application BLA761172 — follow the label that came with the product you were actually prescribed.

The recommended dose of EBANGA for adult and pediatric patients is 50 mg/kg reconstituted, further diluted, and administered as a single intravenous infusion over 60 minutes. ( 2.1 , 2.2 ) See Full Prescribing Information for instructions on preparation, dilution and administration of EBANGA injection. ( 2.2 ) 2.1 Recommended Dosage for Adult and Pediatric Patients The recommended dosage of EBANGA is 50 mg/kg administered as a single intravenous (IV) infusion over 60 minutes. EBANGA must be reconstituted with Sterile Water for Injection, USP then further diluted in 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP prior to IV infusion [see Dosage and Administration (2.2) ] . 2.2. Preparation, Administration, and Storage Instructions EBANGA must be prepared and administered under the supervision of a health care professional. Reconstitution Instructions • Aseptically reconstitute and further dilute EBANGA prior to IV infusion. Do not administer as an IV push or bolus. • More than one vial may be needed for a full dose. Calculate the dose (mg) based on the patient’s actual weight in kg and the number of EBANGA vials required [see Dosage and Administration (2.1) ] . • Prior to reconstitution, allow EBANGA vial(s) to reach ambient temperature (15°C to 27°C [59°F to 81°F]) for approximately 20 minutes. If for any reason reconstitution cannot proceed immediately upon…

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 frequently reported adverse events (≥ 5%) after administration of EBANGA were pyrexia, tachycardia, diarrhea, vomiting, hypotension, tachypnea, and chills. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Emergent BioSolutions at 1-800-768-2304 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 observed in the clinical trials may not reflect the rates observed in practice. Overall, 424 adult and pediatric participants with Orthoebolavirus zairense infection received EBANGA in one clinical trial and as part of an expanded access program during the 2018 Orthoebolavirus zairense outbreak in the Democratic Republic of Congo (DRC). In the PALM trial, the safety of EBANGA was evaluated in a multi-center, open-label, randomized controlled trial, in which 173 participants (119 adults and 54 pediatric participants) with confirmed Orthoebolavirus zairense infection received EBANGA as a single 50 mg/kg IV infusion and 168 participants received an investigational control [see Clinical Studies (14) ] . All participants received optimized standard of care…

Warnings

Important safety information

Hypersensitivity Reactions Including Infusion-Associated Events: Hypersensitivity reactions including infusion-associated events have been reported with EBANGA. 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 EBANGA 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 with EBANGA. 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 EBANGA infusion. In the case of severe or life-threatening hypersensitivity reactions, discontinue the administration of EBANGA immediately and administer appropriate emergency care [see Adverse Reactions (6.1) ]. Infusion could not be completed in 1% of participants who received EBANGA due to infusion-associated adverse events. The rate of infusion of EBANGA 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. EBANGA may reduce the efficacy of the live vaccine. The interval between administration of EBANGA therapy and live vaccination should be in accordance with current vaccination guidelines. ( 7.1 ) 7.1 Vaccine Interactions No vaccine-therapeutic interaction studies have been performed in human participants using EBANGA. However, because of the potential for EBANGA 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 EBANGA. The interval between administration of EBANGA therapy and live vaccination should be in accordance with current vaccination guidelines. The efficacy of EBANGA among participants who reported receipt of a recombinant live vaccine prior to their enrollment in the PALM trial was similar to participants who did not report receiving a vaccine prior to enrollment.
