Indications

NEXOBRID is indicated for eschar removal in adults and pediatric patients with deep partial thickness (DPT) and/or full thickness (FT) thermal burns. Limitations of Use The safety and effectiveness of NEXOBRID have not been established for treatment of: Chemical or electrical burns Burns on the face, perineum, or genitalia Burns on the feet of patients with diabetes mellitus or on the feet of patients with occlusive vascular disease Circumferential burns Burns in patients with significant cardiopulmonary disease, including inhalation injury NEXOBRID is not recommended for: Wounds contaminated with radioactive and other hazardous substances to avoid unforeseeable reactions with the product and an increased risk of spreading the noxious substance.

NEXOBRID contains proteolytic enzymes and is indicated for eschar removal in adults and pediatric patients with deep partial thickness and/or full thickness thermal burns ( 1 ). Limitations of Use The safety and effectiveness of NEXOBRID have not been established for treatment of: Chemical or electrical burns ( 1 ).

Burns on the face, perineum, or genitalia ( 1 ). Burns on the feet of patients with diabetes mellitus or on the feet of patients with occlusive vascular disease ( 1 ). Circumferential burns ( 1 ). Burns in patients with significant cardiopulmonary disease, including inhalation injury ( 1 ). NEXOBRID is not recommended for: Wounds contaminated with radioactive and other hazardous substances to avoid unforeseeable reactions with the product and an increased risk of spreading the noxious substance ( 1 ) Treatment of burn wounds where medical devices (e.g., implants, pacemakers, shunts) or vital structures (e.g., large vessels) could become exposed during eschar removal ( 1 ).

Contraindications

NEXOBRID is contraindicated in patients with [see Warnings and Precautions ( 5.1 ), Description ( 11 )] : Known hypersensitivity to anacaulase-bcdb, bromelain, pineapples, or to any of the other components. Known hypersensitivity to papayas or papain because of the risk of cross-sensitivity. Known hypersensitivity to anacaulase-bcdb, bromelain, pineapples, or to any of the other components ( 4 ). Known hypersensitivity to papayas or papain because of the risk of cross-sensitivity ( 4 ).

Warnings and precautions

Hypersensitivity reactions : Serious hypersensitivity reactions, including anaphylaxis, have been reported with postmarketing use of anacaulase-bcdb. If a hypersensitivity reaction occurs, remove NEXOBRID (if applicable) and initiate appropriate therapy ( 5.1 ). Coagulopathy: Avoid use of NEXOBRID in patients with uncontrolled disorders of coagulation. Use with caution in patients on anticoagulant therapy or other drugs affecting coagulation, and in patients with low platelet counts and increased risk of bleeding from other causes.

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a product cannot be directly compared to rates in the clinical trials of another product and may not reflect the rates observed in practice. Adults: Studies 1 and 2 evaluated subjects undergoing eschar removal for deep partial thickness (DPT) and/or full thickness (FT) thermal burns [see Clinical Studies ( 14 )] .

An integrated analysis of safety data from Studies 1 and 2 compared NEXOBRID (n=177) to standard of care (SOC) (n=149). The SOC treatment included both surgical and non-surgical eschar removal methods. The mean age of the safety population was 35.6 years; 73% were male; 81% were White, 9% were Black, 6% were other races, and 3% were Asian. Regarding burn etiology, 65% had fire/flame burns, 26% had scald burns, 8% had contact burns, and <1% had burns of other etiology.

The mean body surface area (BSA) of wounds that received study treatment was 9.2±5.07%. Mean BSA of all burn wounds was 12.0±6.05%. Of the 177 subjects who were treated with NEXOBRID in Studies 1 and 2, 159 (90%) received one treatment of NEXOBRID, and 18 (10%) received 2 treatments. Table 1 presents adverse reactions that occurred in ≥ 1% of subjects in the NEXOBRID arm and at a higher incidence than the SOC arm, up to 3 months following wound closure.

A total of 139 subjects (69 NEXOBRID, 70 SOC) were treated in the study. The SOC treatment included both surgical and non-surgical eschar removal methods. The mean age was comparable in the NEXOBRID (5.89 years) and SOC (5.75 years) arms. The majority of subjects were male (59% NEXOBRID, 69% SOC). For race, 70% NEXOBRID and 69% SOC subjects were White, 25% NEXOBRID and 23% SOC subjects were Asian, 4% NEXOBRID and 3% SOC subjects were Black or African American, and 1% NEXOBRID and 4% SOC subjects were other races.

For ethnicity, 4% NEXOBRID and 10% SOC subjects identified as Hispanic or Latino. The majority of burns in both treatment arms (NEXOBRID and SOC) were due to scald (68% and 67%). The majority of patients in both treatment groups (NEXOBRID and SOC) had 1 treated wound (71% and 80%, respectively). Table 2 presents adverse reactions that occurred in ≥ 1% of subjects in the NEXOBRID arm and at a higher incidence than the SOC arm, up to 3 months following wound closure.

6.2Postmarketing Experience

The following adverse reactions have been identified during postapproval use of anacaulase-bcdb outside of the United States. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: Hypersensitivity, including anaphylaxis and urticaria
