Clinical Trial Summary

This is an observational study to assess the safety and efficacy of MicroMatrix® alone or in combination with Cytal® Wound Matrix on primary measures of wound healing.

Description:

A single-site, prospective, observational clinical study of Cytal® Wound Matrix alone or in combination with MicroMatrix® for the management of wounds. Up to 100 patients with multiple wound types including but not limited to, venous ulcers, diabetic foot ulcers, trauma wounds, and external surgical wounds will be treated either with Cytal® Wound Matrix alone or with Cytal® Wound Matrix and MicroMatrix® for wounds exceeding 3mm in depth. Wound healing efficacy, effect of treatment on patient-reported quality of life, complete wound management, wound-related adverse event, and wound pathology will be measured. The protocol defined patient follow-up is 12 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Direct Product and Care Costs	Measures the direct cost of products	up to 52 week visit (until study completion)
Other	Indirect Product and Care Costs	Measures the total of the indirect and incidental costs	up to 52 week visit (until study completion)
Other	Return to Work Status	Measures change in "return to work status" and/or "reported work status"	up to 52 week visit (until study completion)
Other	Cost Associated With AEs, UADEs and SAEs	Measure frequency of wound specific events, capturing incident specific costs per event.	up to 52 week visit (until study completion)
Other	Wound Pathology	Measures the effect of treatment through quantitative analysis	Up to 12 weeks
Primary	Number of Participants With Completely Healed Wounds	Assess number of participants with completely healed wounds, defined as 100% epithelialization with no drainage.	Up to 12 weeks
Primary	Wound Size Change	Assess wound size at specified intervals. Number of wounds with 40% reduction by week 4, 60% by week 8, and 80% by week 12.	Up to 12 weeks
Secondary	Time to Complete Wound Closure	Determine time to complete wound closure using Silhouette Star camera system.	up to 52 week visit (until study completion)
Secondary	Wound Characteristics	Identify wound characteristics as determined by granulation tissue quality and presence/quantity of exudate.	up to 52 week visit (until study completion)
Secondary	Incidence of Bridging	Bridging to definitive closure or transition to cellular therapy	up to 52 week visit (until study completion)
Secondary	Visual Analogue Scale (VAS) for Pain	VAS is a psychometric response scale that measures subjective characteristics or attitudes regarding perceived pain levels from participants. Participants are asked to draw a line on a 10cm horizontal line indicating what their current pain level would be. The distance between the start of the horizontal line to the vertical line is calculated in mm with a higher score (100mm) indicating a greater pain intensity.	Up to 52 week visit (until study completion)
Secondary	Wound Quality of Life (W-QOL)	W-QOL is a 17-item Likert style questionnaire that measures 3 subscales in a participant (Body, Psyche, and Everyday to then calculate an overall global score. An overall global score is obtained from averaging all items. Each item is coded with numbers 0 (not at all) to 4 (very much) with a higher score indicating a lower quality of life.	Up to 52 week visit (until study completion)
Secondary	Katz Index of Independence in Activities of Daily Living (KATZ ADL)	The Katz ADL is a 6-item questionnaire measuring independence in activities of daily living such as bathing, dressing, toileting, transfers, feeding, and continence. Each item is dichotomized as either having a score of zero (i.e dependence) or one (i.e. independence). An overall score of 6 indicates full function and an overall score of 2 or less indicates severe functional impairment	Up to 52 week visit (until study completion)
Secondary	Complete Wound Management	Assess the method of application of products and how it is secured as well as adjunctive treatments and dressing.	up to 52 week visit (until study completion)
Secondary	Wound-Related Adverse Events	Number and type of wound-related adverse events as recorded on adverse event case report forms.	up to 52 week visit (until study completion)
