Following the technology appraisal committee meeting on 27 September 2017, NICE released an appraisal consultation document (ACD). Both companies requested to submit additional evidence at this stage, and NICE has agreed to accept this. In this instance, in line with 3.7.29 of the guide to the processes of technology appraisal that says ‘NICE may need to extend timelines and reschedule the subsequent Committee meeting to allow for new evidence to be considered,’ we need to allow the Assessment Group more time to review the additional evidence. Therefore this topic will no longer be discussed at the technology appraisal committee meeting on 23 November 2017, and has been rescheduled for 9 January 2018.
