1 Indications And Usage

EBANGA is indicated for the treatment of infection caused by Zaire ebolavirus in adult and pediatric patients, including neonates born to a mother who is RT-PCR positive for Zaire ebolavirus infection [see Dosage and Administration (2.2) and Clinical Studies (14)].


Limitations of Use:The efficacy of EBANGA has not been established for other species of the Ebolavirus and Marburgvirus genera.Zaire ebolavirus can change over time, and factors such as emergence of resistance, or changes in viral virulence could diminish the clinical benefit of antiviral drugs. Consider available information on drug susceptibility patterns for circulating Zaire ebolavirus strains when deciding whether to use EBANGA.

  • Reconstitution InstructionsAseptically 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 reaching ambient temperature, vials that have NOT been reconstituted may be kept at ambient temperature, protected from light, for no more than 24 hours.Immediately upon reaching ambient temperature, use a sterile 10 mL syringe and an 18-gauge needle to withdraw 7.7 mL of Sterile Water for Injection, USP. Insert the needle tip into the EBANGA vial. Holding horizontally, angle the needle down at an approximate 45° angle, above the lyophilized powder, which has a cake-like appearance. Slowly inject the diluent along the wall of the vial and without any air to avoid foaming and bubbles.Gently swirl (do NOT shake) for approximately 10 seconds; then set the vial down to rest for at least 10 seconds. Repeat until the cake is dissolved. This may take up to 20 minutes.Upon reconstitution, one vial delivers 8 mL of solution that is clear to slightly opalescent and colorless to slightly yellow containing 50 mg/mL of ansuvimab-zykl. Do NOT administer and discard the vial if the reconstituted solution is discolored or contains visible particles.Reconstituted solution in the vials may be kept at ambient temperature (15°C to 27°C [59°F to 81°F]) or stored refrigerated at 2°C to 8°C (36°F to 46°F), protected from light, for up to four (4) hours. This 4-hour window includes time required for further dilution and EBANGA solution should be infused immediately upon further dilution.

  • Dilution InstructionsFollowing reconstitution, EBANGA must be further diluted prior to IV infusion.Use an 18-20 gauge, 1-1.5" needle with an appropriately sized syringe up to 60 mL to perform the dilution steps.Prepare the EBANGA IV dosing solution using an appropriately sized syringe up to 60 mL.For patients weighing > 2 kg, prepare the diluent using either a PVC 0.9% Sodium Chloride Injection, USP IV infusion bag or a non-PVC or non-DEHP Lactated Ringer's Injection, USP IV infusion bag. For patients weighing 0.5 to < 2 kg use a pump-compatible syringe (Table 1).For adult and pediatric patients, either 0.9% Sodium Chloride Injection, USP or Lactated Ringer's Injection, USP can be used as the diluent.The total volume of the infusion solution to be administered is based on the patient's body weight and is specified in Table 1.For patients weighing 0.5 to < 2 kg:-Use a 10 mL syringe compatible with the IV infusion pump.-Fill the 10 mL syringe with the appropriate amount of diluent (Table 1).-Add the calculated volume of EBANGA to the 10 mL syringe (Table 1).-Mix the diluted solution by gentle inversion (3 to 5 times) until admixed. Do not shake. For patients weighing ≥ 2 kg:-Select a diluent solution infusion bag size of appropriate fill volume based on the patient's body weight (see Table 1).-Withdraw and discard from the bag a volume of diluent solution that will leave remaining in the bag the appropriate volume based on the patient's weight (see Table 1). Then add the calculated volume of EBANGA to the bag based on the patient's weight (see Table 1).For example, for a 55 kg patient, withdraw and discard 150 mL of diluent from a 250 mL infusion bag. Then add 55 mL of EBANGA to obtain a total infusion volume of 155 mL.-Gently invert the IV bag 5 to 10 times until the diluted solution is admixed. Do NOT shake.Infuse the EBANGA solution immediately upon dilution. If the diluted infusion solution of EBANGA is not used immediately, it may be stored at ambient temperature or refrigerated at 2°C to 8°C (36°F to 46°F) for up to 4 hours. Do not freeze the diluted solution. If refrigerated, allow the diluted solution to come to room temperature prior to use. These time limits include reconstitution time.Prepare a medical label including patient weight in kg, date and time of product expiration (within 4 hours of preparation).Discard vial(s) and all unused contents.Table 1: EBANGA Volume, Diluent Volume and Total Infusion Volume by Body WeightWeight in kgVolume of EBANGADiluent Volume (mL)The recommended diluent volume ensures the final concentration of the diluted solution is approximately 8-30 mg/mL.,For IV bag administration, the diluent volume column includes the volume of diluent needed to remain in the infusion bag.Final Infusion Volume (mL)Syringe or Infusion Bag Volume for IV Administration0.5 kg1 mL/kg2.5 mL3 mL10 mL syringe compatible with IV infusion pump1 kg5 mL6 mL2 to 10 kg10 mL12 to 20 mL25 mL IV bag11 to 25 kg25 mL36 to 50 mL50 mL IV bag26 to 50 kg50 mL76 to 100 mL100 mL IV bag51 to 100 kg100 mL151 to 200 mL250 mL IV bag101 kg and above150 mL251 mL and above500 mL IV bag

  • AdministrationParenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Do not administer if discolored or if the vial contains visible particles.Do not mix with or administer as an infusion with other medicinal products.Prepare the IV infusion line with 1.2 micron in-line filter extension set.Administer the IV infusion solution over 60 minutes.The diluted EBANGA IV solution can be infused via a central line or peripheral catheter. Do not administer EBANGA as an IV push or bolus.Do not co-administer other drugs simultaneously through the same infusion line.Infusions may be slowed or stopped if necessary, to alleviate any side effects.At the end of the infusion, if a syringe pump was used, then remove the syringe and flush the line with 2 to 5 ml of diluent, but not to exceed the total infusion volume. If an infusion bag was used, replace the empty bag and flush the line by infusing at least 25 mL of the diluent, to ensure complete product administration.

Common Adverse EventsTable 2 summarizes the adverse events that were reported in the PALM trial from a pre-defined list of signs and symptoms that occurred during EBANGA infusion. The evaluation of adverse events in subjects who received EBANGA may have been confounded by the signs and symptoms of the underlying Zaire ebolavirus infection. Twenty nine percent (n=51) of subjects who received EBANGA in the PALM Trial experienced a pre-specified infusion-related adverse event. The most common pre-specified infusion-related adverse event reported in at least 10% of subjects who received EBANGA was fever (Table 2). The adverse event profile in adult and pediatric subjects treated with EBANGA was similar.Table 2: Adverse Events That Occurred During Infusion in >10% of Adult and Pediatric Subjects in the PALM TrialAdverse EventAdverse events in this table were reported on the day of infusion, and included signs and symptoms that occurred during or immediately after infusionEBANGA(N=173)%ControlInvestigational therapy administered as three separate infusions(N=168)%Pyrexia1758Tachycardia932DiarrheaAdverse events that occurred during infusion but were not pre-specified.918Vomiting823Hypotension831Tachypnea628ChillsThe term chills includes other similar adverse events including rigors and tremors533Hypoxia,311The following pre-specified symptoms, which were assessed on a daily basis during admission while admitted to the treatment unit, were reported in ≥40% of subjects who received EBANGA: diarrhea, pyrexia, abdominal pain, and vomiting. Evaluation of these symptoms may have been confounded by the underlying Zaire ebolavirus infection.

Discontinuation and Infusion Rate AdjustmentsApproximately 99% of subjects who received EBANGA in the PALM trial were able to complete their dose within one hour. Two subjects who received EBANGA (1%) did not receive their complete infusion. In eight subjects (5%) the EBANGA infusion rate was decreased due to an AE [see Warnings and Precautions (5.1)].

Risk SummaryZaire ebolavirus infection is life-threatening for both the mother and fetus and treatment should not be withheld due to pregnancy (see Clinical Considerations). Available data from the PALM trial in which pregnant women with Zaire ebolavirus infection were treated with EBANGA demonstrate the high rate of maternal and fetal/neonatal morbidity consistent with published literature regarding the risk associated with underlying maternal Zaire ebolavirus infection. These data are insufficient to evaluate for a drug associated risk of major birth defects, miscarriage, or adverse maternal/fetal outcome.Animal reproduction studies with ansuvimab-zykl have not been conducted. Monoclonal antibodies, such as EBANGA, are transported across the placenta; therefore, EBANGA has the potential to be transferred from the mother to the developing fetus.

Clinical Considerations

Disease-associated maternal and/or embryo/fetal riskMaternal, fetal and neonatal outcomes are poor among pregnant women infected with Zaire ebolavirus. The majority of such pregnancies result in maternal death with miscarriage, stillbirth, or neonatal death. Treatment should not be withheld due to pregnancy.

Risk SummaryThe Centers for Disease Control and Prevention recommend that mothers with confirmed Zaire ebolavirus not breastfeed their infants to reduce the risk of postnatal transmission of Zaire ebolavirus infection.There are no data on the presence of ansuvimab-zykl in human or animal milk, the effects on the breastfed infant, or the effects on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to ansuvimab-zykl are unknown.

Specific PopulationsThe effect of age, renal impairment or hepatic impairment on the pharmacokinetics of ansuvimab-zykl is unknown.

Mechanism of ActionEBANGA (ansuvimab-zykl) is a recombinant, human IgG1κ monoclonal antibody that binds to the glycan cap and inner chalice of the EBOV GP1 subunit. The epitope to which it binds is located within the receptor binding domain of EBOV consisting of amino acids LEIKKPDGS (GP residues 111–119).Ansuvimab-zykl binds EBOV GP without the mucin domain with a KD of 0.2 nM at pH 7.4 and 0.6 nM at pH 5.3 as measured by biolayer interferometry. Ansuvimab-zykl blocks binding of EBOV GP1 to the Neiman Pick cell receptor 1 in host cells (IC50 value of 0.09 μg/mL), inhibiting virus entry into the host cell. Ansuvimab-zykl exhibited Fc-mediated Antibody Dependent Cellular Cytotoxicity (ADCC) activity against cells expressing EBOV GP when effector cells were added.

Antiviral ActivityIn a live virus plaque-reduction neutralization assay performed in Vero E6 cells, ansuvimab-zykl neutralized Zaire ebolavirus Mayinga with an EC50 value of 0.06 µg/mL. In an EBOV GP lentivirus infectivity assay using HEK293 cells, ansuvimab-zykl inhibited Zaire ebolavirus Mayinga with an EC50 value of 0.09 μg/mL and Zaire ebolavirus Makona with an EC50 value of 0.15 μg/mL. The ADCC activity of ansuvimab-zykl was assessed in EBOV GP-transduced and non-transduced HEK293T target cells in the presence of antibody with effector cells added at an effector-to-target cell ratio 1:50 and analyzed via flow cytometry. Ansuvimab-zykl mediated ADCC, with maximal activity observed at a mAb concentration of 0.03 μg/mL. Treatment of Zaire ebolavirus infected rhesus macaques with a single IV dose of ansuvimab-zykl (50 mg per kg) generally protected infected animals from Zaire ebolavirus mediated death when drug was administered 5 days post-infection.

ResistanceNo nonclinical or clinical studies evaluating resistance to ansuvimab-zykl have been conducted. The possibility of resistance to ansuvimab-zykl should be considered in patients who either fail to respond to therapy or who develop relapse of disease after an initial period of responsiveness.

Immune ResponseInteraction studies with recombinant live EBOV vaccines and EBANGA have not been conducted [see Drug Interactions (7.1)].

4 Contraindications


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 subjects 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)].

6 Adverse Reactions

  • The following clinically significant adverse reactions are described elsewhere in the labeling:Hypersensitivity Reactions Including Infusion-Associated Events [see Warnings and Precautions (5.1)]

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 subjects with Zaire ebolavirus infection received EBANGA in one clinical trial and as part of an expanded access program during the 2018 Zaire ebolavirus 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 subjects (119 adults and 54 pediatric subjects) with confirmed Zaire ebolavirus infection received EBANGA as a single 50 mg/kg IV infusion and 168 subjects received an investigational control [see Clinical Studies (14)]. All subjects received optimized standard of care treatment (oSOC). The median age of the study population that received EBANGA was 26 years (range: 1 day to 85 years). Fifty-five percent (55%) of enrolled subjects were female and 45% were male.During the same outbreak, 251 subjects (173 adults and 78 pediatric subjects) with laboratory-confirmed Zaire ebolavirus infection received EBANGA under an expanded access program; 57% of whom were female and 43% of whom were male. Ages ranged from 6 days to 80 years, with a median age of 25 years.

6.2 Immunogenicity

As with all therapeutic proteins, there is potential for immunogenicity from using ansuvimab-zykl. There are no data to assess the effects of potential immunogenicity on efficacy and safety in subjects with Zaire ebolavirus infection.

7.1 Vaccine Interactions

No vaccine-therapeutic interaction studies have been performed in human subjects using EBANGA. However, because of the potential for EBANGA to inhibit replication of a live vaccine virus indicated for prevention of Zaire ebolavirus 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 subjects who reported receipt of a recombinant live vaccine prior to their enrollment in the PALM trial was similar to subjects who did not report receiving a vaccine prior to enrollment.

8.4 Pediatric Use

The safety and effectiveness of EBANGA for the treatment of infection caused by Zaire ebolavirus have been established in pediatric patients from birth to less than 18 years of age. Use of EBANGA for this indication is supported by evidence from a multi-center, open label, randomized controlled trial of EBANGA in adults and pediatric subjects that included 54 pediatric subjects birth to less than 18 years of age, including neonates born to a mother who is RT-PCR positive for Zaire ebolavirus infection. Of the total number of subjects administered EBANGA in the PALM trial, pediatric subjects (1 day to 17 years) accounted for 31% (n=54) of the study population in the PALM trial. The 28-day mortality and safety in adult and pediatric subjects treated with EBANGA were similar [see Adverse Reactions (6.1), and Clinical Studies (14)]. An additional 78 (31%) pediatric subjects from birth to less than 18 years of age received EBANGA in an expanded access program.

8.5 Geriatric Use

Clinical trials of EBANGA did not include sufficient numbers of subjects aged 65 and over to determine whether the safety profile of EBANGA is different in this population compared to younger subjects. Of the total number of subjects administered EBANGA in the PALM trial, 6 subjects (3%) were 65 years or older. The limited clinical experience has not identified differences in responses between the elderly and younger subjects.

11 Description

Ansuvimab-zykl is a Zaire ebolavirus (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.

12.1 Mechanism Of Action

Ansuvimab-zykl is a recombinant human monoclonal antibody with antiviral activity against Zaire ebolavirus [see Microbiology (12.4)].

12.2 Pharmacodynamics

Ansuvimab-zykl exposure-response relationship and the time course of pharmacodynamic response is unknown.

12.3 Pharmacokinetics

Limited data from 18 healthy subjects 22 to 56 years of age suggests that the pharmacokinetic profile of ansuvimab-zykl is consistent with the profile of other IgG1 monoclonal antibodies.Pharmacokinetic data are not available for Zaire ebolavirus infected patients.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity, genotoxicity and fertility studies have not been conducted with ansuvimab-zykl.

14 Clinical Studies

The efficacy of EBANGA has been evaluated in 174 subjects with confirmed Zaire ebolavirus infection in the PALM trial, a multi-center, open-label, randomized, controlled trial sponsored by the National Institute of Allergy and Infectious Diseases (NIAID; NCT03719586). The trial was conducted in the North Kivu and Ituri provinces in the Democratic Republic of Congo, where an outbreak began in August 2018, and enrolled 681 subjects of all ages, including pregnant women, with documented Zaire ebolavirus infection and symptoms of any duration who were receiving oSOC. Subjects were randomized to receive EBANGA 50 mg/kg IV as a single infusion, an investigational control 50 mg/kg IV every third day, for a total of 3 doses, or other investigational drugs. Eligible subjects had a positive reverse transcriptase-polymerase chain reaction (RT-PCR) for the nucleoprotein (NP) gene of Zaire ebolavirus and had not received other investigational treatments (with the exception of experimental vaccines) within the previous 30 days. Neonates ≤7 days of age were eligible if the mother had documented infection. Neonates born to a mother who had cleared Zaire ebolavirus following a course of her assigned investigational medication were also eligible to be enrolled at investigator discretion regarding the likelihood that the neonate was infected. Randomization was stratified by reverse transcription-PCR cycle threshold calculated using NP targets (CtNP ≤22.0 vs >22.0; corresponding to high and low viral load, respectively) and Ebola Treatment Unit (ETU) site. All subjects received oSOC consisting, at a minimum, of IV fluids, daily clinical laboratory testing, correction of hypoglycemia and electrolyte imbalances, and broad-spectrum antibiotics and antimalarials, as indicated.The primary efficacy endpoint was 28-day mortality. The primary analysis population includes all subjects who were randomized and concurrently eligible to receive either EBANGA or the investigational control during the same time period of the trial.The demographics and baseline characteristics are provided in Table 4 below.Table 4: Demographics and Baseline Characteristics in PALM TrialParameterEBANGA N=174N (%)Control N=168N (%)CtNP = cycle threshold calculated using NP targets; IQR=interquartile range; AST=Aspartate aminotransferase; ALT=Alanine aminotransferase; ETU=Ebola treatment unit.Mean age (years)27.329.9Age <1 month, n (%)4 (2)2 (1)Age 1 month to <1 year, n (%)7 (4)5 (3)Age 1 year to <6 years, n (%)15 (9)12 (7)Age 6 years to <12 years, n (%)13 (7)5 (3)Age 12 years to <18 years, n (%)15 (9)9 (5)Age 18 years to <50 years, n (%)93 (53)114 (68)Age 50 years to <65 years, n (%)21 (12)18 (11)Age ≥65 years, n (%)6 (3)3 (2)Female, n (%)98 (56)87 (52)  Positive result on pregnancy testPregnancy positive test was calculated based on subjects who were pregnant.
