About the PREMIER Trial 
The PREMIER trial is an international, randomized, double-blind, two-arm placebo-controlled, pivotal Phase III study, 
evaluating the efficacy and safety of PXT3003 versus placebo in mild-to-moderate CMT1A patients, over a 15-month 
period. The dose of PXT3003 tested in the PREMIER trial corresponds to the high dose ('HD') tested in the prior Phase 
III trial ('PLEO-CMT'). As agreed with regulatory agencies, the primary efficacy endpoint will be the Overall 
Neuropathy Limitations Scale ('ONLS') which measures functional motor disability. The secondary endpoints include the 
following outcome measures: 1) 10-Meter Walk Test ('10mWT'), 2) Quantified Muscular Testing (bilateral foot 
dorsiflexion dynamometry), 3) Patient Global Impression of Severity ('PGI-S'), 4) Patient Global Impression of Change 
('PGI-C'), 5) Charcot-Marie-Tooth Neuropathy Score, version 2 ('CMTNS-v2'), and 6) Quantified Muscular Testing (hand 
grip). Safety and tolerability will be monitored throughout the study. Further information on the PREMIER trial can be 
found on the ClinicalTrials.gov website (study identification number: NCT04762758) here.
