Remarks:
Senior Vice President of Regulatory, Quality, Clinical Operations, and Technical Operations This Form 4/A amends the Form 4 filing made on behalf of the Reporting Person on March 14, 2023. The Form 4, as originally filed, inadvertently omitted the cancelled stock option grant of 4,452 shares.
