Brief 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.

Condition or disease Intervention/treatment Phase
Diabetic Foot Ulcer Device: COMS One device Device: Sham device Not Applicable

Detailed 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).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 320 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

The purpose of this clinical trial is to evaluate the safety and effectiveness of treatment with the COMS One device in subjects with refractory DFUs. The randomized, sham-controlled, double-blinded 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 SOC, in the treatment of DFUs.

Following randomization, subjects will be assigned treatment with either COMS One device or the Sham device in conjunction with SOC. At least 50% of subjects are required to be 65 years or older at randomization.

Prospective, randomized, double-blinded, placebo-controlled trials provide the most objective methods for analyzing the outcomes of multiple treatment groups. The blinded use of a sham device allows for a true comparison of COMS One treatment in conjunction with SOC to SOC alone.

Masking: Double (Participant, Investigator)
Masking Description:

Permuted block randomization across all sites will be applied to generate randomization codes. Both the COMS One device and the Sham device will be prepared to appear to be identical to the subject to achieve the double-blind purposes and each device will be given a unique serial identifier.

To avoid assessment bias, each site will have an Inter-observer (blinded assessor) who will be blinded to treatment and perform and document all assessments of the target DFU evolution. Following target DFU assessment, the treatment will be performed by another assigned clinician, who will not have any involvement with the Inter-observer. This will provide an adequate level of masking to ensure that the trial is double-blinded.

Arm Intervention/treatment
Active Comparator: COMS One device

The COMS One device is reusable (the component can be used on multiple subjects and is cleaned between uses). The COMS One device is the housing unit for the user controls, displays and functions including embedded software, lithium-ion battery, optical (LEDs) and a magnetic stimulation coil.

The COMStouch is a sterile single-use component. The COMStouch provides a base and sterile barrier for the COMS One device.

The COMSfix component is a self-adhesive single-use strap used to hold the COMS One device and COMStouch components in place during treatment.

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.
