Clinical Trial Summary

To evaluate the Koya wearable device - a Novel Portable Non-Pneumatic Active Compression Device (NPCD) in contrast to an advanced pneumatic compression device (APCD)

Description:

A Multi-center Randomized Control Single Cross-over Study to Evaluate the Safety and Effectiveness of Dayspring, a Novel Portable Non-Pneumatic Active Compression Device (NPCD) vs. an Advanced Pneumatic Compression Device (APCD) for Treating Lower Extremity Lymphedema. To evaluate the Dayspring, a Novel Portable Non-Pneumatic Active Compression Device (NPCD) in contrast to an advanced pneumatic compression device (APCD) in a multi-centered setting to evaluate volume, quality of life, safety, adherence, and preference.

• Diagnosis of acute thrombophlebitis (in last 6 months)

• Diagnosis of pulmonary embolism or deep vein thrombosis within the previous 6 months

• Diagnosis of pulmonary edema

• Diagnosis of congestive heart failure (uncontrolled/uncompensated)

• Diagnosis of chronic kidney disease with acute renal failure

• Diagnosis of epilepsy

• Subjects with poorly controlled asthma

• Any condition where increased venous and lymphatic return is undesirable

• Women who are pregnant, planning a pregnancy or nursing at study entry

• Participation in any clinical trial of an investigational substance or device during the past 30 days

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Limb volume reduction or maintenance	Limb volume measurement is performed by using a calibrated tape measure to measure circumference from the ankle at 4cm increments to the waist region. Measurements to be taken for both lowerr extremities. Volume is calculated based on cylindrical segment analysis. The outcome measure is assessed as a difference or change from baseline to month 3	3 months
Primary	LYMQOL	The Lymphedema Quality of Life Questionnaire (LYMQOL), a validated disease-specific QoL tool, is also administered at baseline and month 3. Overall QoL is scored on a single item by the patient on a scale of 1-10. The outcome measure is assessed as a difference or change from baseline LYMQOL at day zero and month 3	3 months
Primary	Therapy adherence tracking	A table will be provided to patient to document days of use with the device to track adherence	3 months
Secondary	Safety/AEs	As assessed by reported adverse events	3 months
Secondary	Patient survey on preference	A study survey administered at the end of the study to measure patient preference between the two devices	3 months
