Brief Summary:
This post-approval study will follow 60 participants who have ALS, documented chronic hypoventilation, and bilateral phrenic nerve function, and who undergo the surgical implantation procedure to receive the NeuRx Diaphragm Pacing System device. Participants who are successfully implanted with the device will use it for daily diaphragm conditioning sessions. Participants will be followed for at least two years (until the last enrolled participant reaches the 2-year follow-up visit). Safety and probable benefit outcome measures will be assessed.
Detailed Description:
This is a prospective, non-randomized, open-label, interventional, post-approval (FDA) study of the NeuRx Diaphragm Pacing System (DPS) device. The study will enroll 60 participants who have amyotrophic lateral sclerosis (ALS), meet the FDA-approved device indications for use, and undergo the surgical implantation procedure to receive the device. The device is intended for use in ALS patients with a stimulatable diaphragm (both right and left portions) as demonstrated by voluntary contraction or phrenic nerve conduction studies, and who are experiencing chronic hypoventilation (CH), but not progressed to an FVC less than 45% predicted. Participants who are successfully implanted with the device will use it for daily diaphragm conditioning sessions. Participants will be followed for at least two years (until the last enrolled participant reaches the 2-year follow-up visit). Safety and probable benefit outcome measures will be assessed. The primary objective of the study is: (1) (Safety) Characterize the types and frequency of major device-related adverse events (AEs) over the time of device use. Secondary objectives of the study are: (2) (Safety) Determine whether the frequency of major device-related AEs increases dramatically toward end of life; and (3) (Probable Benefit) Determine whether there is a relationship between survival time and onset type (bulbar and limb), time from onset to treatment, and use of NIV, riluzole, or PEG in patients treated with the device.
