Clinical Trial Summary

The purpose of this clinical trial is to evaluate the safety and effectiveness of the treatment with the COMS One device in subjects with refractory diabetic foot ulcers (DFUs). The prospective randomized, double-blinded, sham-controlled trial is designed to demonstrate superiority of wound closure of the COMS One device to a sham-control device at 12 weeks post-application, when each is administered in conjunction with standard of care (SOC) in the treatment of DFUs.

Description:

The purpose of this clinical trial is to evaluate the safety and effectiveness of the treatment with the COMS One device in subjects with refractory diabetic foot ulcers (DFUs). The prospective randomized, double-blinded, sham-controlled trial is designed to demonstrate superiority of wound closure of the COMS One device to a sham-control device at 12 weeks post-application, when each is administered in conjunction with standard of care (SOC) in the treatment of DFUs. Primary Objective The COMS One Therapy System is intended to promote wound healing in chronic DFUs. As part of the clinical investigation, the primary objective is to determine complete wound healing at 12 weeks post-application of the device defined as complete skin re-epithelialization without drainage confirmed by 2 consecutive trial visits 2 weeks apart. Secondary Objectives Secondary objectives are confirmation of safety and assessment of wound healing parameters as well as subject and site reported outcomes. A total of 320 subjects with refractory DFU will be screened. It is expected that 30% of subjects will be excluded from the trial if either of the following occur between screening and randomization: >30% wound closure over a period of 2 weeks or >50% wound closure over a period of 4 weeks (measured post-debridement). The remaining 224 subjects will be randomized into two groups (112 Subjects Sham device treated; 112 Subjects Coms One device treated).

5. Wagner Grade 3, 4 or 5

6. Participation in another trial with investigational drug or device within the 30 days preceding and during the present trial

7. Any co-morbid medical condition which places the subject at unreasonable risks in the opinion of the investigator (such as history of HIV or a clinically significant cardiac, gastrointestinal, endocrine, neurological, liver, or kidney disease) of the investigator)

8. Subject has chronic renal insufficiency requiring dialysis (end stage renal disease)

9. Subject is being treated with systemic corticosteroids (prednisone, dexamethasone, hydrocortisone, methylprednisolone, or similar) >10mg/day for more than 10 days or any dose >30 days

10. For subjects in the 2-Week Run-In Phase: more than 30% closure of target DFU at Screening Run-In Phase Visit I or Randomization/Baseline Visit or more than 50% closure of target DFU between the 2 Week Historical Period and Randomization/Baseline Visit (measured post-debridement)

11. For subjects in the 4-Week Run-In Phase: more than 30% closure of target DFU at Screening Run-In Visit II or between Screening Run-In Phase Visit II and Randomization/Baseline Visit or more than 50% closure of target DFU between Screening Run-In Phase Visit I and Randomization/Baseline Visit (measured post-debridement)

12. Blood chemistry or counts values as follows (based on subject's medical files):

1. Pre-albumin <10 mg/dL

2. Serum BUN >60 mg/dL

3. Serum creatinine >4.0 mg/dL

4. WBC <2.0 x 109/L

5. Hemoglobin <8.0 g/dL

6. Absolute neutrophil <1.0 x 109/L

7. Platelet count <50 x 109/L

8. HbA1C >12%

Intervention

Device:
• COMS One device
The COMS One device incorporates technologies for optical and magnetic stimulation. The optical stimulation component is designed to emit light by two types of light emitting diodes (LEDs) in the wavelength of 660 nm (red) and 830 nm (near infrared) range of the electromagnetic spectra. The magnetic stimulation component is generated by a coil emitting pulse modulated magnetic fields in the extremely low frequency (ELF) range of the electromagnetic spectra. The System is a lightweight, portable device. The device is applied via a single use disposable component (COMStouch) that provides a base and sterile barrier for the unit. The device is attached via a single use strap (COMSfix). The device has been slightly adapted in order to make sure blinding is achieved/maintained. The specific feature that has been modified for the purposes of blinding is sensor detecting whether the device is lying on the skin.
• Sham device
The Sham device is a lightweight, portable device. The device is applied via a single use disposable component (COMStouch) that provides a base and sterile barrier for the unit. The device is attached via a single use strap (COMSfix). The device has been slightly adapted in order to make sure blinding is achieved/maintained. The specific features that have been modified for the purposes of blinding include the following: 1) therapeutic output, and 2) sensor detecting whether the device is lying on the skin.
