That trial was testing the effectiveness of VX-864. This is a possible treatment for patients suffering from alpha-1 antitrypsin deficiency (AATD) with the PiZZ genotype. According to the company, it saw statistical improvement from 2.2 to 2.3 in mean functional alpha-1 antitrypsin levels.

Vertex Pharma also notes that the study was well tolerated by patients. It also points out that the study confirmed its proof of concept for an oral small molecule corrector to promote the proper folding of the mutant Z-AAT protein.
