Trial to Evaluate the Safety and Effectiveness of Treatment With COMS One Device in Subjects With Diabetic Foot Ulcers

Concurrent Optical and Magnetic Stimulation (COMS) for Treatment of Refractory Diabetic Foot Ulcer; a Prospective Randomized, Sham-controlled, Double-blinded, Pivotal Clinical Trial

• Status: Recruiting
• Phase: N/A

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 through 24 weeks post-application, when each is administered in conjunction with standard of care (SOC) in the treatment of DFUs.

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 through 24 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 time to complete wound healing, 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 450 subjects with refractory DFU will be screened. It is expected that 50% of subjects will be excluded from the trial if either of the following occurs 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) to account for approximately 10% missing data due to early trial withdrawal or missed endpoint assessment.

Interventions

Type	Name	Description
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 COMS One is a lightweight, portable device. The device is locally 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 purpose of blinding is sensor detecting whether the device is lying on the skin.
DEVICE	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.
