Backed by five randomized controlled trials and more than 100 peer-reviewed publications, Kerecis® MariGen® is FDA-cleared for use over bone and tendon—supporting provider confidence in documentation, clinical outcomes, and product selection in today’s evolving reimbursement landscape
Patients treated with Kerecis had a 1.6x greater chance of healing and healed nearly two weeks faster.
DFUs classified as University of Texas (UT) grades 2 and 3 are some of the most challenging wounds to treat, and are associated with higher rates of infection, delayed healing, and increased risk of amputation.1
The increased risk associated with grade 2 and 3 diabetic foot ulcers stems from their depth and complexity.
Increased Depth and Complexity creates:
- Penetration down through the dermis and subcutaneous tissue
- Depth creates environment for bacterial growth
- Exposed structures avascular and with limited capability for fighting infection
- Granulation tissue needs to migrate over exposed structures
For patients with University of Texas (UT) grade 2 and 3 ulcers – the severe cases where bone or tendon is exposed – the stakes of having an open wound are high:
- Higher risk of infection2
- Up to 80% increased risk of amputation3
- Increased healthcare costs per patient4
- 5-year mortality rates of up to 45%5
Kerecis understands that managing deep, complex DFUs can be difficult, especially when evidence-based options are limited. These wounds carry a significant burden for patients and their families, yet historically there has been little large-scale, randomized clinical data to help guide treatment decisions.
To help address this gap, the Odinn RCT was designed to evaluate healing outcomes in DFUs with exposed structures and provide clinicians with meaningful, comparative evidence.”

Confidently Manage DFUs with MariGen
As you evaluate advanced options for challenging DFUs, MariGen offers a biologically rich, intact fish-skin graft designed to support healing in deep, complex wounds.
The MariGen product line includes multiple variations and sizes to meet diverse DFU needs and is indicated for full-thickness wounds extending through the dermis to deeper tissues— including subcutaneous fat, muscle, bone, and tendon.
This allows care providers to confidently manage DFUs with exposed structures using a solution backed by growing clinical evidence.
