One of each pair is randomized to treatment with EVs in conjunction with standard of care. The other wound of each pair receives standard of care alone, without EV treatment. All wounds on study continue to receive standard of care throughout the study. For the EV treated wounds, up to six administrations of EVs occur approximately two weeks apart over a period of 10 weeks. If the treated wound closes prior to six administrations, no additional doses are given unless the wound reopens during the treatment period, in which case the original retreatment schedule resumes but is not extended. Subjects with wound closure identified at one of the treatment visits should return for all subsequent visits to verify wound closure and assess the scar quality of the wound, unless the closure is identified at the final study visit, in which case no additional visits are required.\n\nWound closure is determined by complete re-epithelialization that is not subject to re-injury during dressing changes or as a result of normal daily activities (e.g., wearing clothing, eating, sleeping). This is confirmed by the investigator at least two weeks after initial closure (unless closure is identified at the final study visit). At the conclusion of the 10-weektreatment period, the wounds are followed every 4 weeks for a period of 12 weeks. At no time during the study does closure status of the control wound influence the EV treatment or visit schedule.\n\nSTUDY OBJECTIVES:\n\nPrimary Objectives:\n\nDetermine the safety of applying multiple administrations of EVs derived from allogeneic MSCs to 10-50 cm2 RDEB wounds that have persisted for at least four weeks\n\nDetermine if EVs plus standard of care can promote wound healing in RDEB subjects compared to standard of care alone control\n\nSecondary Objectives: Determine if there is clinical benefit of applying EVs to RDEB wounds\n\nPLANNED SAMPLE SIZE: 8 subjects will be treated on the protocol with AGLE-102.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '6 Months', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1. Subjects must be 6 months or older at screening.\n2. Subjects who have a confirmed diagnosis of DEB based on electron microscopy, immunomapping, or genetic testing. Subjects with severe DEB (e.g., RDEB patients with absent Col VII/no anchoring fibrils) and milder forms of DEB (e.g., RDEB patients with reduced Col VII and/or anchoring fibril levels) are eligible.\n3. Presence for at least four weeks of two 10 - 50 cm2 wounds (unroofed EB erosions) at least 4 inches apart that can be considered similar enough in size, wound location and expected healing characteristics to be a matched pair. Neither index wound may have been treated with any local (topical, subcutaneous, etc) or systemic therapeutic other than standard of care treatments described in this protocol (i.e. local or systemic antimicrobials to control infection, topical anesthetic and oral analgesics if required) in the past 3 months prior to screening.\n4. Females of childbearing potential must have a negative urine or serum pregnancy test at screening and agree to continue use of an acceptable form of birth control throughout the duration of the study. Acceptable forms of birth control include oral, implant, injectable, and transdermal contraceptives; an intrauterine device; or other forms considered acceptable by the investigator. A female subject is eligible to participate if she is not pregnant, is not a woman or childbearing potential (WOCBP), or is a WOCBP who agrees to follow the contraceptive guidance above.\n5. Post-pubertal males who agree to use an acceptable method of contraception for the duration of the study.\n6. Subjects 18 years of age and older must be capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Subjects under the age of 18 years must be capable of giving assent (if age-appropriate), and/or they must have a guardian capable of providing consent.\n7. Willing to comply with the protocol requirements.\n\nNote: Reference to Appendix 3 can be located in the protocol\n\nExclusion Criteria:\n\n1. Concomitant treatment at the time of screening or at any time during the study of either study wound (control or AGLE-102 treated) with local or systemic therapy other than standard of care treatments described in this protocol (i.e. local or systemic antimicrobials to control infection, topical anesthetic and oral analgesics if required). Concomitant treatment of non-study wounds with local therapy during the study is acceptable. Systemic treatment of RDEB wounds (except as noted for standard of care) during the study is not acceptable. Subjects unwilling to abstain from prohibited concomitant treatment of study wounds (treated or control) and/or systemic treatment of RDEB wounds during the study period are excluded.\n2. Either study wound located within 6 inches of wounds treated concurrently with any other local therapy.\n3. Clinical evidence of systemic infection.\n4. History of bone marrow transplantation.\n5. Diagnosed clinically significant autoimmune disease\n6. Wound that extends across the fingers, toes, pubic or perineum region are excluded from being index wounds.\n7. The subject has clinical evidence of an active infection at the wound site.\n8. Current malignancy (including skin cancer), a life expectancy of \\< 2 years, or severe cardiopulmonary disease that restricts ambulation to the clinical facility.\n9. History of coagulopathy.\n10. Chronic use of systemic steroids or immunosuppressive agents.\n11. Allergy to human albumin, streptomycin, or penicillin.\n12. The subject is likely to be a recipient of tissue or organ transplantation.\n13. Current history of alcohol or substance abuse or has a history of alcohol or substance abuse that required treatment within the previous 12 months.\n14. History of poor compliance or unreliability.\n15. Females who are pregnant, nursing, or planning a pregnancy during their participation in the study.\n16.
