Prospective Case Registry for Wounds

Wound Healing Delayed

This is a post-market, observational and non-interventional registry to collect real-world data in diverse clinical settings and wound applications of acellular fish skin graft (FSG). The registry will be multi-center , target a wide patient population and a variety of wounds to document the quality of wound care, patient outcomes, safety and long-term results.

Introduction: This registry will be conducted according to US standards of Good Clinical Practice as adopted by the Food and Drug Administration, associated Federal regulations and applicable institutional research policies and procedures. This study has been approved by a central IRB, WCG IRB in April 2023. Registry Objectives: The overall objective of the registry is to collect quality and safety data to assess the efficacy of the FSG in treatment of acute and chronic wounds. The ultimate goal of the registry is to enhance quality of care, patient outcomes and establish a resource to facilitate the use of FSG in treatment of acute and chronic wounds. Primary Objective: The main purpose of the registry is to evaluate the safety and long-term effectiveness of acellular fish skin grafts in treatment of acute and chronic wounds in a real world setting. Secondary Objective: To evaluate the clinical and financial benefits of FSG in terms of quality of healing, pain and treatment cost. Research Design: This registry will prospectively collect data from treatment and follow-up of patients who have undergone procedures where wounds are treated with Kerecis FSG. The registry is a non-experiment, multi-center , single arm, open label study to determine real world long-term safety and quality of Kerecis FSG. The study will not be interventional, de-indentified, HIPAA compliant data will only be collected on patients already scheduled to receive the Kerecis product. Subjects will be enrolled as they are scheduled to receive FSG for treatment of their index wound. Subjects will complete follow up as scheduled by their physician and their data will be documented at weekly follow-ups through week 32. Clinical improvement will be collected through case report forms (CRF) at each time point. Subjects will be followed for the 32 weeks but if the Index wound heals before that time , there will be a Healing Confirmation Visit (HCV) 2 weeks after to confirm the Index wound is still healed. If Index wound is not healed at the HCV then the subject will continue to next weekly visit. Index wound assessments will be captured digitally. The depth of the index wound will be collected manually by using a sterilized cotton swab placed in the deepest part of the wound and documenting that measurement. One year form the procedure, patients will receive a survey to evaluate their overall experience and provide any feedback. Overall, the registry is prospective except information regarding patient medical history can be collected retrospectively. Registry Procedures: Specific Training: Prior to subject enrollment , the Sponsor will initiate in person training with participating sites to provide training to the physicians and their staff about the protocol, registry procedures and data entry. The sponsor will implement a number of strategies to ensure to ensure the quality, consistency and interpretability of data recorded. Training, education and ongoing liason with participating sites will be provided to support high quality data collection. Data Management and Quality Plan: Data De-identification: Subjects enroll in the registry will be assigned a unique subject identification number. This number will consist of ten characters for the registry protocol number, three digits for a site number and four digits for a sequentially assigned subject number (i.e.,0001, 0002 etc.) Data confidentiality, storage, and Retention: All clinicians and related medical staff involved in looking after patients during the study are bound by medical confidentiality and are obliged to comply with data protection follow all Health Information Portability and Accountability Act of 1996 (HIPAA) and Protected Health Information (PHI). Data will be collected in a CRF and entered into secure, web-based portal databases. The databases are housed and managed in an International Organization for Standardization (ISO) 27001 certified environment. Only authorized users and site administrators can see site wide data. Surgeon users can only see their procedure. The registry will contain built-in exporting function to enable data extraction by participating sites to help clinicians review their practice and improve the services. The paper form CRF will be stored in a locked file cabinet at the participating sites and will be shredded after 7 years post completion of the registry. Data Quality: The registry will implement several strategies to maintain data quality and consistency such as routine cleaning, quality check and periodic feedback. Training, education and ongoing liason with participating sites will be provided to supporting high quality data collection.
