  Purpose

Non-invasive ventilation or BiPAP®, which is a form of breathing support delivered through a facemask, is a successful treatment for the respiratory complications of amyotrophic lateral sclerosis (ALS). It has been shown to prolong survival, improve quality of life, and improve cognitive function. It is widely used among patients with ALS who have advanced breathing difficulties. It is not known whether there is benefit to using non-invasive ventilation earlier in the disease course.

There is evidence that non-invasive ventilation may slow down the decline in breathing function. If this were true then it would make sense to start non-invasive ventilation use earlier than the current clinically accepted practices.

The purpose of this study is to determine whether using non-invasive ventilation early in the course of disease can slow the decline in breathing function.

Patients remain in the study for 6 months and are asked to make 7 clinic visits during which time they will undergo pulmonary function tests and complete questionnaires.

Primary Outcome Measures:
  • Decline in forced vital capacity

Secondary Outcome Measures:
  • quality of life
  • respiratory quality of life

Estimated Enrollment: 60
Study Start Date: April 2002
Study Completion Date: September 2007
Detailed Description:

This is a randomized, crossover trial for patient with ALS and mild respiratory involvement. Patients with forced vital capacity above 60% of the predicted value can join. Patients will be assigned to either start using non-invasive ventilation at night or continue their usual care. After three months, patients will switch over to the other treatment group. For example, a patient who was initially assigned to continue their usual care would begin using non-invasive ventilation after three months.
