What this trial studies

This study aims to assess the safety outcomes of patients with Cerebral Adrenoleukodystrophy (CALD) who have been treated with elivaldogene autotemcel (eli-cel) in a post-marketing setting. It will follow 120 participants over a period of 15 years to evaluate newly diagnosed malignancies and major functional disability-free survival. A specific cohort of 24 participants with more advanced CALD will also be monitored for effectiveness outcomes as required by the FDA. No investigational drug will be administered during this observational study.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with CALD who have been treated with eli-cel and are receiving follow-up care from a US-based physician.

Not a fit: Patients who have not been treated with eli-cel or those outside the specified geographic locations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and effectiveness of eli-cel for patients with CALD.

How similar studies have performed: While this study is observational and focuses on post-marketing safety, similar studies have shown promising results in assessing long-term outcomes for gene therapies.
