ClinConnect Summary

This clinical trial is studying a product called Xcell Amnio Matrix™ (XAM) to see how well and how safely it helps heal different types of wounds, including diabetic foot ulcers, venous leg ulcers, and wounds after Mohs surgery (a type of skin cancer surgery). The study aims to find out how much the wound size changes over 12 weeks when XAM is applied once a week along with standard wound care.

Adults 18 years and older who have certain types of wounds that have not healed well with usual treatment might be eligible. For example, people with diabetic foot ulcers need to have diabetes controlled with medication and wounds that have lasted between 4 weeks and 1 year, located below the ankle, and of a specific size. Those with venous leg ulcers should have wounds caused by vein problems, located between the ankle and knee, and suitable for compression therapy. People with wounds from Mohs surgery that are a certain size might also qualify. Participants will visit the clinic about once a week for 12 weeks to receive treatment and have their wounds checked, with a follow-up visit two weeks after treatment ends. It’s important that participants are generally healthy, able to follow the care instructions, and willing to use birth control if applicable. This study is not yet recruiting, but it offers a chance for people with hard-to-heal wounds to try a new treatment under medical supervision.

• • 1. Subject is 18 years of age or older.
• 2. For subjects with DFU:
• • 1. Subject has diabetes mellitus (Type 1 or Type 2), requiring insulin or oral/injectable medications to control blood glucose levels
• • 2. Glycosylated hemoglobin (HbA1c) level is \<12%
• • Note: Prior documented HbA1c within 12 weeks of Screening is acceptable.

• • 5. Ulcer location is at or below the ankle (malleolus)
• • 6. Subject is amenable to use of off-loading, as needed for planter ulcer
• • 7. Ulcer extends through the full thickness of the skin but not down to muscle, tendon, or bone
• OR, For subjects with VLU:
• • 1. Subject with ulcer primarily caused by venous insufficiency
• • 2. Duration of ulcer is ≥ 4 weeks but ≤ 1 year, unresponsive to SOC
• • 3. Ulcer area is ≥ 1.5cm2 and ≤ 20cm2 and with a clean, granulating base with minimal adherent slough at the Baseline Visit
• • 4. Ulcer location is at or above the ankle (malleolus) and below the knee
• • 5. Ulcer location is appropriate for use of compression therapy treatment
• • 6. Ulcer extends through the full thickness of the skin but not down to muscle, tendon, or bone
• • OR, For subjects with post-operative defects after Mohs surgery
• • a. ≥6 mm (in greatest diameter or length of circular or oval geometric shape) at the Baseline Visit
• • 3. Subject is at least 12 weeks post lower extremity revascularization procedure, if one has been performed.
• • 4. Subject is in general good health, with no clinically significant medical conditions or abnormalities that, in the opinion of the Investigator, would interfere with study participation, the assessment of study endpoints, or pose additional risk to the subject.
• 5. Adequate circulation to the affected lower extremities as demonstrated by one of the following within 12 weeks of screening:
• • 1. Dorsum transcutaneous oxygen measurement (TCOM) ≥ 30 mmHg,

• • Female subject/partners of non-childbearing potential are defined as surgically sterile (e.g., bilateral tubal ligation, hysterectomy) or two years postmenopausal at time of screening.
• • All male subjects (excluding men who have been sterilized) with female partners of child-bearing potential must agree to consistently and correctly use a condom for the duration of the study. In addition, subjects may not donate sperm for the same time period.
