Long Term Follow-up Study in Patients With Telomere Biology Disorders With Bone Marrow Failure Who Completed Study EXG-US-01

Overview

This is a long-term rollover follow-up study for Phase I/II study (Protocol EXG-US-01).

Detailed description

Patients who received EXG34217 treatment and had at least one follow-up visit (Month 1, 3, 6, or 12) in Study EXG-US-01 will be eligible for this rollover study. Patient will sign a consent form prior to any study related procedure. This study is to add additional follow-up assessments up to 6 years after EXG34217 treatment. This study does not have additional intervention. Additional visits will be every 6 months in the first 3 years and once a year for two years.
