Its development was marked by successes and setbacks, and ultimately resulted in failure with the product being withdrawn from the market by its manufacturer Amylyx earlier this year. Our purpose here is to learn from this in order to inform future drug development in rare diseases. In the second article to follow, we will look at the late-stage ALS pipeline and see how sponsors are responding to these challenges and the promise they hold for improving the lives of ALS patients.
