Updated 08/2009

Purpose and Rationale:

The manufacturer reports that experience with HFCWO via The VestTM in other diagnoses has shown reduced hospitalizations, decreased need for antibiotics, improved quality of life and improved pulmonary function scores. This study will assess pulmonary function with and without HFCWO and measure pulmonary complications in patients with ALS. 

Study Details:

This is a randomized, parallel study design with two arms: Vest treatment and non-vest treatment. It will be conducted at six sites nationwide. Participants completed baseline surveys, underwent pulmonary function testing and CO2 and oxygen saturation measurements. These measurements and surveys were taken during clinic visits at 4 and 12 weeks. Also, participants were required to take a daily Peak Expiratory Flow (PEF) measurement (a pulmonary function test), and completed a daily log recording PEF scores and tracking use of HFCWO therapy (for the treatment arm). At the end of three months, participants in both the treatment and non-vest treatment arms had the option to use HFCWO for the next 6 months, submitting additional survey and pulmonary function measurements at 24 and 36 weeks.

Advanced Respiratory, Inc, is the study sponsor with Dr. Hiroshi Mitsumoto serving as the medical advisor for the trial.
