What this trial studies

This observational long-term follow-up enrolls patients who received BEAM-101 in the parent BTX-AUT-001 protocol and consent to extended monitoring. Participants will have periodic safety and efficacy assessments with annual in-person visits through Year 5, then in-person visits every three years through Year 11, and a final visit at Year 15. Virtual or phone check-ins occur every six months through Year 5 and annually thereafter to capture interim events. There are no exclusion criteria beyond having received BEAM-101 and providing informed consent, and collected data will inform durability and late-effect profiles of the base-editing therapy.

Who should consider this trial

Good fit: Ideal candidates are patients with sickle cell disease who received BEAM-101 in BTX-AUT-001, are completing that study's end-of-study visit, and can provide informed consent and attend scheduled visits.

Not a fit: Patients who did not receive BEAM-101 or who are unable or unwilling to complete long-term in-person or remote follow-up are unlikely to benefit from this follow-up.

Why it matters

Potential benefit: If successful, this follow-up could provide important long-term safety and durability information that helps guide care for people treated with BEAM-101.

How similar studies have performed: Long-term follow-up of other gene and cell therapies has yielded valuable safety and durability data, but BEAM-101's base-editing approach is relatively novel and lacks extensive long-term results.
