Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This early-stage trial tests a one-time treatment called BE-101 for adults with severe hemophilia B. The therapy uses a person's own blood cells, modified with CRISPR gene editing, to continuously produce the missing clotting factor. The goal is to reduce or prevent bleeding episodes. The study will enroll 24 participants to check safety and how well the treatment works.
