As you will be aware the Department for Health and Social Care has asked NICE to carry out a Single Technology Appraisal of lentiGlobin within its anticipated marketing authorisation for treating transfusion-dependent beta-thalassaemia. The appraisal is expected to start in approximately early August 2019 when we will write to you about how you can get involved. The deadline for submissions is expected in approximately early October 2019. These timings are based on a request from the company to reschedule the initial date set by NICE until after the anticipated marketing authorisation has been received, enabling additional evidence to be considered and to align with when the company hopes to launch the product in England and Wales.
