A Long-Term Safety Follow-up Registry for Patients Who Received Treatment With Prademagene Zamikeracel for Recessive Dystrophic Epidermolysis Bullosa (RDEB) in the Post-Marketing Setting
What this study is about
The goal of this observational study is to evaluate the long-term safety and wound healing durability (up to 15 years) for participants with Recessive Dystrophic Epidermolysis Bullosa (RDEB) who were treated with pz-cel. The main questions it aims to answer are: * The long-term safety profile of pz-cel. * The wound healing durability of pz-cel.
View original scientific description
The goal of this observational study is to evaluate the long-term safety and wound healing durability (up to 15 years) for participants with Recessive Dystrophic Epidermolysis Bullosa (RDEB) who were treated with pz-cel. The main questions it aims to answer are: * The long-term safety profile of pz-cel. * The wound healing durability of pz-cel. * The occurrence of all malignancies after treatment with pz-cel, regardless of type or location, in individuals who received pz-cel treatment for RDEB in the post-marketing setting. Participants will then be followed annually up to 15 years post-treatment. Assessments will occur via remote data collection. If the participants provider determines an office visit is necessary after the first year, some of this data can be collected in person as well. Annual assessments will include, but are not limited to: * Review of Adverse Events (AEs), Serious Adverse Events (SAEs), hospitalizations, and any evidence of malignancies and potential retroviral infection * Wound-healing durability data collection via the modified Caregiver Global Impression of Change for Wound Healing * Any changes in concomitant medications and procedures.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
