Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Title A Multicenter, Prospective, Randomized Controlled Modified Multi-Platform (Matriarch) Trial Evaluating Several Cellular, Acellular, and Matrix-like Products (CAMPs) and Standard of Care versus Standard of Care alone in the Management of Nonhealing Diabetic Foot and Venous Leg Ulcers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To determine the between-arm difference in the proportion of subjects achieving complete closure of nonhealing diabetic foot ulcers and venous leg ulcers with multiple CAMPs plus SOC versus SOC alone over 12 weeks using a modified dual platform (Matriarch) trial design.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

For a platform trial design, the allocation ratio is equal to the square root of the number of Intervention groups. This study will include 4 Intervention groups and 2 Control groups. A treatment effect of 0.35, significance level of 5%, 80% power, and a 1.4:1:1 for the VLU platform and 1.4:1:1 ratio for the DFU platform.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects The potential subject must be at least 21 years of age or older.
* The potential subject must have a diagnosis of type 1 or 2 Diabetes mellitus.
* At enrollment, the potential subject must have a target ulcer with a minimum surface area of 1.0 cm2 and a maximum surface area of 20.0 cm2 measured post debridement.
* The potential subject must have a target ulcer that has been present for a minimum of 4 weeks and a maximum of 52 weeks of standard of care, prior to the initial screening visit.
* The potential subject must have a target ulcer located on the foot with at least 50% of the ulcer below the malleolus.
* The potential subject must have a target ulcer that is Wagner 1 or 2 grade, extending at least through the dermis or subcutaneous tissue and may involve the muscle provided it is below the medial aspect of the malleolus.
* The potential subject's affected limb must have adequate perfusion confirmed by vascular assessment. Any of the following methods performed within 3 months of the first screening visit are acceptable:

1. ABI between 0.7 and ≤ 1.3;
2. TBI ≥ 0.6;
3. TCOM ≥ 40 mmHg;
4. PVR: biphasic.

* The potential subject must be at least 21 years of age or older.
* At enrollment, the potential subjects must have a target ulcer with a minimum surface area of 1 cm2 and a maximum surface area of 20 cm2 measured post-debridement.
* The potential subject must have a target ulcer that has been present for a minimum of 4 weeks and a maximum of 52 weeks of standard of care prior to the initial screening visit.
* The potential subject has no visible signs of healing objectively, less than 40% reduction in wound size in the last 4 weeks.
* The potential subject's affected limb must have adequate perfusion confirmed by vascular assessment. Any of the following methods performed within 3 months of the first screening visit are acceptable:
