Indications & Usage
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) ] .
EBANGA™ (ansuvimab-zykl) is a Zaire ebolavirus glycoprotein (EBOV GP)-directed human monoclonal antibody 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.
( 1 ) Limitation 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.
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.

Adverse Reactions
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) ] The most frequently reported adverse events (≥ 5%) after administration of EBANGA were pyrexia, tachycardia, diarrhea, vomiting, hypotension, tachypnea, and chills.

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.
Common Adverse Events Table 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 Trial Adverse Event Adverse events in this table were reported on the day of infusion, and included signs and symptoms that occurred during or immediately after infusion EBANGA (N=173) % Control Investigational therapy administered as three separate infusions (N=168) % Pyrexia 17 58 Tachycardia 9 32 Diarrhea Adverse events that occurred during infusion but were not pre-specified.
9 18 Vomiting 8 23 Hypotension 8 31 Tachypnea 6 28 Chills The term chills includes other similar adverse events including rigors and tremors 5 33 Hypoxia , 3 11 The 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 Adjustments Approximately 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) ] .
Selected Laboratory Abnormalities in the PALM Trial Table 3 presents selected laboratory abnormalities (worsening to Grade 3 or 4 compared to baseline) in the PALM trial.

There are no data to assess the effects of potential immunogenicity on efficacy and safety in subjects with Zaire ebolavirus infection.
