A Pilot Study of the Utility of 3D Printed Masks for ALS Subjects

Status Terminated

Clinical Trial Summary

Non-invasive ventilation (NIV) is an important therapy for patients with a number of neurological diseases. Specifically, NIV has been shown to be an effective treatment for people with amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), which is a fatal, non-curable, progressive disease of the motor neurons. However, due to changes in facial structure associated with the disease, many ALS patients find that traditional NIV masks don't fit well. In this study, investigators will perform a feasibility study on NIV mask interfaces which are custom designed for each ALS patient and then manufactured via 3D printing.

Clinical Trial Description

Non-invasive ventilation (NIV) is an important therapy for patients with a number of neurological diseases. Specifically, for amyotrophic lateral sclerosis (ALS)--a fatal, non-curable, progressive disease of the motor neurons--NIV represents one of the most effective treatments with a survival benefit of greater than 1 year. Despite this survival advantage, and the corresponding improvement in Quality of Life (QoL), compliance with NIV can be poor. Factors contributing to poor compliance to NIV include bulbar onset disease and mask leaks. In addition to reduced adherence to therapy, elevated mask leaks can compromise the pressure adjustment algorithm in average volume assured pressure support (AVAPS) ventilation, a commonly used mode of bilevel (positive airway pressure) PAP therapy in ALS. In an effort to increase NIV compliance in subjects with neurological conditions, and specifically ALS, investigators hypothesize that a better fit achieved through 3D printed NIV mask interfaces may improve utilization by decreasing mask leaks, decreasing the required delivery pressures and improving compliance with therapy. Investigators therefore propose a feasibility study to investigate the use of 3D printing to manufacture customized NIV mask interfaces for subjects with ALS who encounter difficulty using NIV because of poorly fitting mask interfaces despite exhausting available commercial mask options. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
