The safety profile of StrataGraft with regard to wound-related events* was similar to that of autograft treatment sites in clinical studies

Adverse reactions reported at a frequency of ≥2% (N=119) following treatment with StrataGraft® in 4 pooled trials1, †

Table comparing number of patients affected and severity of adverse reactions Table comparing number of patients affected and severity of adverse reactions

*Including erythema, swelling, local warmth, and wound site infections.

†Safety data include patients enrolled in 4 randomized studies, including 2 clinical studies in patients with DPT thermal burns (STRATA2011 and STRATA2016) and 2 clinical studies in patients with full-thickness complex skin defects due to thermal burns or other causes.

‡If a patient had more than 1 incidence of an adverse reaction, the patient was counted only once.

StrataGraft is an effective, safe alternative to autograft for DPT burns

Based on clinical trial results:

  • Overall, the safety profile of StrataGraft with regard to wound-related events was similar to that of autograft1
  • No patients discontinued study participation due to adverse reactions1
  • There have been no clinical reports of rejection reaction to StrataGraft1
  • The wound infection rate was similar to autograft-treated sites (2 patients with treatment-emergent adverse events of infection in each treatment arm)1,2
How does StrataGraft fit into the current workflow?

IMPORTANT SAFETY INFORMATION
Important Safety Information

Contraindications

  • Do not use in patients with known allergies to murine collagen or products containing ingredients of bovine or porcine origin.

Warnings and Precautions

  • StrataGraft contains glycerin. Avoid glycerin in patients with known sensitivity (irritant reaction) to glycerin.

  • Severe hypersensitivity reactions may occur. Monitor for both early and late symptoms and signs of hypersensitivity reaction following StrataGraft application, and treat according to standard medical practice.

  • StrataGraft contains cells from human donors and may transmit infectious diseases or infectious agents, eg, viruses, bacteria, or other pathogens, including the agent that causes transmissible spongiform encephalopathy (TSE, also known as Creutzfeldt-Jakob disease [CJD or variant CJD]).

    StrataGraft is a xenotransplantation product because of an historic exposure of the keratinocyte cells to well-characterized mouse cells. The cell banks have been tested and found to be free of detectable adventitious agents, and mouse cells are not used in the manufacture of StrataGraft; however, these measures do not entirely eliminate the risk of transmitting infectious diseases and disease agents.

    Transmission of infectious diseases or agents by StrataGraft has not been reported.

  • Because StrataGraft is a xenotransplantation product, StrataGraft recipients should not donate whole blood, blood components, plasma, leukocytes, tissues, breast milk, ova, sperm, or other body parts for use in humans.

Adverse Reactions

  • The most common adverse reactions (incidence ≥2%) were itching (pruritus), blisters, hypertrophic scar, and impaired healing. Other adverse events reported are included in the full Prescribing Information.

Pediatric Use

  • The safety and effectiveness of StrataGraft in pediatric patients (<18 years) have not been established.

Please see full Prescribing Information.

Seventy-one adult patients aged 19 to 79 who sustained 3% to 37% TBSA thermal burns on the torso, arms, or legs were enrolled in the phase 3 clinical trial. In each patient, 2 DPT areas of comparable depth were randomized to either cryopreserved StrataGraft or autograft.1,2

The anatomic treatment sites for StrataGraft included upper extremities (n=31; 43.7%), lower extremities (n=25; 35.2%), and trunk (n=15; 21.1%).2
