Warnings/Precautions

Concerns related to adverse effects:

• Hypersensitivity: Reactions to vancomycin, amikacin, or product excipients may precipitate severe hypersensitivity reactions, including anaphylaxis, with prademagene zamikeracel application. Dyspnea, itching, hives, nausea, runny nose, swelling, and watery eyes have occurred.

• Infection: Prademagene zamikeracel is derived from human and bovine reagents and has a risk of transmitting infectious diseases caused by known or unknown agents. Although human and animal-derived reagents are tested for animal viruses, bacteria, fungi, and mycoplasma prior to use, these measures may not eliminate the risk of transmission of these or other infectious diseases/agents.

• Insertional oncogenesis: There is a potential risk of retroviral vector-mediated insertional oncogenesis following treatment with prademagene zamikeracel. Patients may develop malignancies and should be monitored lifelong. If a malignancy occurs, contact the manufacturer (1-844-888-2236) for reporting and to obtain instructions on collection of samples for testing.

Prescribing and Access Restrictions

Prademagene zamikeracel is shipped directly to qualified treatment centers and is patient specific.

Administration: Adult

Topical: Prademagene zamikeracel topical application is a surgical procedure performed in an appropriate setting (eg, operating room under aseptic conditions) by a qualified health care provider. Refer to manufacturer's labeling for administration technique.

Administration: Pediatric

Note: For autologous use only; confirm patient identity matches unique patient identifiers on patient-specific label. Prademagene zamikeracel is manufactured from patient-specific biopsies and is supplied in up to 12 sheets for a single application.

Topical: Prepare wound by debridement under appropriate anesthesia. Apply unaltered prademagene zamikeracel sheet(s) onto wound bed using resorbable sutures during a single surgical session. Do not trim sheets or overlap sheets on wounds. Cover area with nonadhesive dressings and topical antibiotic ointment. Treated area should be left undisturbed for 5 to 10 days after application as clinically appropriate. Keep dressings dry and do not submerge treated area in water until gauze backing of prademagene zamikeracel falls off (usually within 2 to 3 weeks after application). Materials that have come into contact with prademagene zamikeracel should be disposed of as surgical biohazardous waste.

Use: Labeled Indications

Recessive dystrophic epidermolysis bullosa: Treatment of wounds in adult and pediatric patients with recessive dystrophic epidermolysis bullosa.

Metabolism/Transport Effects

None known.

Drug Interactions

There are no known significant interactions.

Reproductive Considerations

Patients who could become pregnant should use effective contraception at the time of treatment.

Pregnancy Considerations

Animal reproduction studies have not been conducted.

Breastfeeding Considerations

It is not known if prademagene zamikeracel is present in breast milk.

According to the manufacturer, the decision to breastfeed should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.

Monitoring Parameters

Monitor lifelong for post application malignancies secondary to retroviral vector mediated insertional oncogenesis; application-related infection or irritation (eg, fever, increased drainage, worsening pain, swelling); signs and symptoms of hypersensitivity; antidrug antibodies.

Mechanism of Action

In patients with recessive dystrophic epidermolysis bullosa (RDEB), both copies of the COL7A1 gene are mutated, resulting in the absence or low levels of biologically active C7 protein that form anchoring fibrils (AFs). The lack of AFs disrupts the connection between the epidermis and the dermis and causes skin fragility and other signs and symptoms of RDEB. Prademagene zamikeracel consists of a patient's own cells that have been gene-modified through retroviral vector transduction to express the COL7A1 gene to produce the C7 protein. These cells are formed into cellular sheets for topical application onto wounds.
