Study Population

Subjects with Gaucher disease who previously received the investigational gene therapy product AVR-RD-02

You may qualify if:

  • Subject must be willing and able to provide written informed consent for the JAB-GD-001 study in accordance with applicable regulations and guidelines and to comply with all study visits and procedures.
  • Subject must have been enrolled in the preceding AVROBIO AVRO-RD-02-201 treatment study and have received AVR-RD-02 treatment

You may not qualify if:

  • Subject has any medical, psychological, or other condition that, in the opinion of the Investigator:
  • Might interfere with the subject's participation in the study (including consenting to procedures); and/or
  • Poses any additional risk to the subject; and/or
