Brief Summary:

This is a multi-center, long-term safety and efficacy follow-up study for subjects with cerebral adrenoleukodystrophy (CALD) who have received Lenti-D Drug Product in Study ALD-102.

After completing Study ALD-102 (approximately 2 years), eligible subjects will be followed for an additional 13 years for a total of 15 years post-drug product infusion. No investigational drug product will be administered in this study.


Condition or disease Intervention/treatment
Cerebral Adrenoleukodystrophy (CALD) Adrenoleukodystrophy (ALD) X-Linked Adrenoleukodystrophy (X-ALD) Other: Safety and efficacy assessments

Study Type : Observational
Estimated Enrollment : 25 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Long-term Follow-up of Subjects With Cerebral Adrenoleukodystrophy Who Were Treated With Lenti-D Drug Product
Study Start Date : January 2016
Estimated Primary Completion Date : November 2033
Estimated Study Completion Date : November 2033


Group/Cohort Intervention/treatment
Subjects treated with Lenti-D
Subjects who have received Lenti-D Drug Product in Study ALD-102 (bluebird bio-sponsored clinical trial) and who meet the eligibility criteria for the study LTF-304
Other: Safety and efficacy assessments
Vector copy number (VCN) measurement, safety evaluations, disease-specific assessments, and assessments to monitor for long-term complications of autologous transplant




Primary Outcome Measures :
  1. Overall survival of subjects with cerebral adrenoleukodystrophy (CALD) treated with Lenti-D Drug Product [ Time Frame: 15 years post-drug-product infusion ]
  2. Proportion of subjects who experience new, persistent or worsening chronic GVHD [ Time Frame: 15 years post-drug-product infusion ]
  3. Proportion of subjects who undergo subsequent stem cell transplantation [ Time Frame: 15 years post-drug-product infusion ]
  4. All drug product-related AEs [ Time Frame: 15 years post-drug-product infusion ]
  5. All SAEs (regardless of relatedness to drug product) [ Time Frame: 15 years post-drug-product infusion ]
  6. Incidence of vector-derived RCL, assessed from archived samples as clinically indicated. [ Time Frame: 5 years post-drug-product infusion ]
  7. Monitoring for clonal dominance using integration site analysis (ISA) [ Time Frame: 15 years post-drug-product infusion ]
  8. Monitoring for clinical signs of oncogenesis [ Time Frame: 15 years post-drug-product infusion ]
  9. MFD-free survival [ Time Frame: 15 years post-drug-product infusion ]

Secondary Outcome Measures :
  1. Change from baseline in Loes score [ Time Frame: 15 years post-drug-product infusion ]
  2. Change from baseline in Neurological Function Score (NFS) [ Time Frame: 15 years post-drug-product infusion ]
  3. Monitoring of status of gadolinium enhancement (through MRI) from entry into Study LTF-304 [ Time Frame: 15 years post-drug-product infusion ]

Criteria

Inclusion Criteria:

  • Provision of written informed consent for this study by the subject or subject's parent(s)/ legal guardian(s) and written informed assent by subject, if applicable
  • Have received Lenti-D Drug Product in Study ALD-102
  • Able to comply with study requirements.

Exclusion Criteria:

  • Met the VCN discontinuation criterion from Study ALD-102, as follows: the subject has undetectable VCN (<0.0003 copies per cell) in peripheral blood cells for 2 consecutive measurements at least 1 month apart and at least 12 months after drug product infusion. This exclusion criterion does not apply to subjects who received allo-HSCT after Lenti-D Drug Product infusion in Study ALD-102.
