Is this trial a fit for you?

Likely a good fit

Adults with active lower-extremity lymphedema who are candidates for the advanced pneumatic compression device per device indications and can consent and comply with the protocol.

Probably not a fit

Individuals with the listed exclusion conditions or who do not respond to compression therapy may not experience benefit from the revised programming.

What this trial studies

This early-phase study compares a revised compression programming for an advanced pneumatic compression device against the current method to see if it improves lymphatic movement and propulsion in adults with active lower-extremity lymphedema. Participants may also receive a contrast dye-free lymphatic imaging approach. The trial will enroll adults who qualify for the device and can comply with the protocol at UTHealth Houston, under sponsor Tactile Medical. Safety considerations include common exclusion factors such as heart failure, acute venous disease, severe arterial disease, infection, active cancer in the leg drainage area, or eczema and scarring. The study uses a pilot design to gather initial signals of lymphatic function improvement and device tolerability.

Why it matters

Potential benefit: If successful, participants could experience improved lymph movement and symptom relief from better compression therapy.

How similar studies have gone: Prior studies in compression therapy for lymphedema have shown potential improvements in lymphatic function with optimized device settings, though this specific revised programming is novel.
