简要总结
This prospective, multi-center, randomized, controlled clinical study compares NuShield® plus SOC to SOC alone in subjects with chronic DFUs. NuShield® will be used along with standard of care on diabetic foot ulcers of greater than 6 weeks which have not adequately responded to conventional ulcer therapy.
详细描述
Two hundred (200) subjects with a chronic DFU ranging in size from 0.5cm2 and 25 cm2 will be randomized 1:1 to either NuShield® and SOC or SOC alone following the 14 day screening period. Following screening and randomization, subjects shall be seen weekly for up to 24 weeks. For subjects that heal prior to week 24, a healing confirmation visit shall occur two weeks later to confirm maintenance of complete wound closure.
Subjects that are randomized into the SOC group whose DFU has not healed by week 12 may be crossed over to receive NuShield® and followed for an additional 12-14 weeks.

入选标准
- •At least 18 years old and maximum of 85 years old.
- •Subjects with a diabetic foot ulcer that is either superficial, e.g. not involving tendon, capsule, or bone; or wounds that penetrate into tendon, capsule, bone and/or joint.
- •Subjects, with the presence of Diabetes, must have a Glycosylated hemoglobin (HbA1c) ≤ 12% within 4 weeks prior to randomization
- •Index ulcer (i.e. current episode of ulceration) has been present for greater than 4 weeks prior to the initial screening visit with no upper limit in duration of non-healing.
- •Subject has adequate circulation to the foot as documented by either: Skin perfusion pressure (SPP) measurement of ≥ 45 mmHg, Toe-brachial index (TBI) ≥ 0.6/ Toe pressure greater than 40, Ankle-brachial index (ABI) between 0.60 and ≤ 1.3
- •Index ulcer is a minimum of 0.5 cm2 and a maximum of 25cm2 at randomization, prior to first study treatment.
- •The index ulcer has been offloaded for 14 days prior to randomization.
- •Index ulcer has not reduced in area > 20% from Day -14 to Day 0, prior to randomization.
- •Subject understands and is willing to participate in the clinical study and can comply with weekly visits and the follow-up regimen.
- •Subject, or their Legally Authorized Representative (LAR), has read, understood, and signed the IRB/IEC approved Informed Consent Form before screening procedures are undertaken.
排除标准
- •Index ulcer(s) deemed by the investigator to be caused by a medical condition other than diabetes.
- •Treatment with HBO wound dressings that include growth factors, bioengineered tissues, or skin substitutes within 30 days of randomization.
- •History of bone cancer or metastatic disease of the affected limb or chemotherapy within the 12 months prior to randomization.
- •Subjects with a history of more than two weeks treatment with immunosuppressants (including prednisone 10 mg daily or an equivalent does of other oral steroids cytotoxic chemotherapy, or application of topical steroids to the ulcer surface within one month prior to first Screening Visit, or who receive such medications during the screening period, or who are anticipated to require such medications during the course of the study.
- •Subject is on any investigational drug(s) or therapeutic device(s) within 30 days preceding the first Screening Visit.
- •History of radiation at the ulcer site.
- •Index ulcer has been previously treated or will need to be treated with any prohibited therapies within 30 days prior to randomization.
- •Presence of any condition(s) which seriously compromises the subject's ability to complete this study or has a known history of poor adherence with medical treatment.
- •Active infection at the index ulcer at the time of Randomization.
- •Acute osteomyelitis or bone infection of the affected foot, where subject has received less than 4 weeks of systemic antibiotics at the time of Screening and less than 6 weeks prior to Randomization (systemic antibiotic regimen must be completed at the time of Randomization).
- •Subject's with suspected infection who have received less than 2 weeks of systemic antibiotics, or have not had surgical resection of clinically diagnosed osteomyelitis
- •Subjects with suspected osteomyelitis who have not had an X-ray, CT scan or MRI within 14 days prior to Randomization.
- •Subject is unwilling or unable to comply with the study requirement for offloading the index wound
- •Subject is pregnant or breast feeding.
