Mirragen Diabetic Foot Ulcer Study

Recruiting now

Conditions studied: Diabetic Foot Ulcer, Osteomyelitis Chronic

In brief

This study is being done to collect data from treatment of patients who have diabetes with non-healing foot wounds and are being treated with a resorbable and biocompatible borate-based bioactive glass fiber matrix. A borate-based bioactive glass fiber matrix is used to cover the ulcer for wound management. The primary objective of this study is to evaluate the safety and efficacy of the borate-based bioactive glass fiber matrix in the treatment of diabetic foot ulcers in a real-world setting. The secondary objective is to evaluate the clinical and financial benefits in terms of quality of healing, pain, and treatment cost.

• Subject has an ulcer with a Wagner Grade 2 or 3 classification Wagner Grade 2: Deep ulcer extended to ligament, tendon, joint capsule, bone, or deep fascia without abscess or osteomyelitis Wagner Grade 3: Ulcers extend to the deep tissue and have either associated soft tissue abscess or osteomyelitis If Wagner Grade 3 Ulcer with chronic osteomyelitis, that can be debrided in an outpatient setting, in the opinion of the investigator
• Exposed or palpable bone in the reference ulcer, that can be surgically excised in an outpatient clinic setting, using local anesthetic, at the screening or randomization visit
• Less than a 1cm margin of peri-ulcer tissue of the reference ulcer, requiring surgical debridement, at the screening and randomization visit
• Wagner Grade 3 subjects must have osteomyelitis diagnosed by:
• X-ray: suggestive or positive for changes consistent with chronic osteomyelitis or Positive probe to bone (PTB) test or Strong clinical suspicion, in the opinion of the Investigator, in the presence of osteomyelitis in the index wound

• If female, subjects must have been practicing adequate contraception (abstinence, barrier method, hormonal, or IUD). Must agree to using an accepted and effective form of birth control during the study.
• Subject has adequate circulation to the affected extremity, as demonstrated by at least ONE of the following tests within 60 days (about 2 months) prior to enrollment:
• A.Ankle-Brachial Index (ABI) of study leg(s) of ≥0.7 to ≤1.3 in conjunction with doppler arterial waveforms, which are triphasic or biphasic at the ankle of affected leg Or B.Toe brachial Index (TBI) of ≥ 0.50 OR C.Great Toe Pressure 50mmHg OR D.Dorsum transcutaneous oxygen test (TcPO2) of study leg(s) of ≥40mmHg on the dorsum of the affected foot OR E.Palpable pulses
