Hyperspectral Imaging to Assess and Predict Diabetic Foot Ulcers

Diabetic Foot Ulcers Clinical Trial

Official title:
Hyperspectral Imaging to Assess and Predict Diabetic Foot Ulcers

Clinical Trial Summary

This study is designed to test a prototype imaging instrument that relies on Medical HyperSpectral Imaging (MHSI) technology for the assessment and prediction of diabetic foot ulceration and wound healing. The imaging system utilizes the biomarkers of oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb), in the upper layers of skin on the foot as: a metric for assessing wound healing, a reflection of microvascular disease, and determining tissue at risk for forming new ulcers. MHSI results will also be compare with ABI and TcPO2 measurements.

Clinical Trial Description

ULCER HEALING STUDY: This is a study comparing measurements from a cohort of 66 diabetic subjects (30 Type 1 and 36 Type 2) with at least one foot ulcer. The study will take place at three medical centers. Each center will enroll 22 subjects (10 Type 1 and 12 Type 2). Subjects will be required to participate in eleven (11) clinic visits over a 6 month period. The first visit will last approximately three hours and each of the other visits will last about two hours. The eleven visits will be scheduled as follows in the Table to the right.

At the initial visit the subject will give informed consent and a full medical history, and will schedule the dates of the remaining visits for the study. The subject recruiter will contact each subject one week prior to each subsequent visit to either confirm the subject's attendance or to re-schedule the visit.

NEW ULCER PREDICTION STUDY: This is a study comparing measurements of 210 "high risk" diabetic subjects (90 Type 1 and 120 Type 2) over an 18-24 month period. The study will take place at three medical centers. Each center will enroll 70 subjects (30 Type 1 and 40 Type 2). Subjects will all be required to participate in nine (9) clinic visits. The nine visits will be scheduled as follows in the Table to the right.

The first visit will last approximately three hours and each of the other visits will last about 2 hours. At the initial visit the subject will give informed consent and a full medical history, and will schedule the dates of the visits for the rest of the study. The subject recruiter will contact each subject one week prior to each subsequent visit to either confirm the subject's attendance or to re-schedule the visit. ;
