MINNEAPOLIS, Dec. 07, 2017 — Tactile Systems Technology, Inc. (“Tactile Medical”) (Nasdaq:TCMD), a medical technology company focused on developing medical devices for the treatment of chronic diseases at home, today announced the publication of a functional use study in the medical journal Head & Neck that assessed the Company’s Flexitouch system for the treatment of lymphedema of the head and neck. Flexitouch is the first and only pneumatic compression device that is FDA 510(k) cleared for at-home head and neck lymphedema treatment in the United States.
The Study, titled Usability of advanced pneumatic compression to treat cancer-related head and neck lymphedema: A feasibility study, was conducted by Mayrovitz et al. and included 44 participants. It was designed to evaluate the feasibility of using the Flexitouch system to help patients with head and neck lymphedema self-manage their condition. The American Cancer Society estimates that 400,000 people in the U.S. today have head and neck cancer, with 60,000 new patients diagnosed annually. Ridner et al from Vanderbilt University recently published a study in Lymphatic Research and Biology indicating that greater than 75% of head and neck cancer patients will develop some form of lymphedema following head and neck cancer treatment. With this in mind, this Study assessed aspects including safety, garment fit, treatment comfort, and the participant’s likeliness to use Flexitouch at home. Researchers also measured anatomical areas on the patient’s head and neck before and after treatment in order to assess acute changes in edema, an important indicator of treatment efficacy.  The Study found statistically significant reductions in face and neck measurements after a single 32-minute treatment with Flexitouch. Importantly, statistically significant reductions in composite metrics (mean ± SD) of the face (82.5 ± 4.3 cm pre vs. 80.9 ± 4.1 cm post; P < .001) and neck (120.4 ± 12.2 cm pre vs. 119.2 ± 12.1 cm post; P < .001) were reported. Overall, 43% of patients had a >2% reduction in composite face measurements, and 20% of patients had a >2% reduction in composite neck measurements after a single 32-minute treatment. A 2% change in these composite measurements has been established in prior literature as the threshold evidencing clinically significant reduction in head and neck lymphedema. We believe small changes in edema in the head and neck may have a major effect on breathing, swallowing and speaking. Patient-reported outcomes were also positive: 82% of patients found the treatment with Flexitouch comfortable; 61% felt better after a single treatment; and 93% reported that they were likely to use Flexitouch at home. Researchers concluded that Flexitouch is safe, easy to use, and well-tolerated, while demonstrating edema reduction after a single 32-minute treatment session.“We are encouraged by the findings of this study, which provide important clinical support for the safety, effectiveness and patient acceptance of our Flexitouch system in treating head and neck lymphedema,” said Gerald R. Mattys, Chief Executive Officer of Tactile Medical. “We are pleased to offer a new, at-home treatment option for patients suffering from head and neck lymphedema and are excited by the potential long-term outcomes they may be able to achieve through its use.”The study may be found online at: http://onlinelibrary.wiley.com/doi/10.1002/hed.24995/fullAbout Tactile MedicalTactile Medical is a leader in developing and marketing at-home therapy devices that treat lymphedema and chronic venous insufficiency.
