In this post I’ll go over some relevant discussion in NICE’s March 2024 Integrated Performance Report as related to guidance timelines.
“In 2022/23, NICE reduced the time taken to deliver guidance on medicines following GB marketing authorisation (MA) by 17%. In 2023/24, we aim to reduce the time by a further 15%.”

NICE characterizes topics as “optimal” or “divergent”.
One characteristic of an “optimal” topic is:
“NICE is notified of topic >16 months ahead of GB marketing authorisation.”

NWBO notified NICE in December of ’22. Sixteen months from then is May of ’24.
The days between a GB marketing authorisation and final TA/HST guidance for an optimal topic in the ’22/’23 period is:
✅55 days (Mean)
✅62 days (Median)

What does this mean?
With the goal of an additional 15% improvement in timelines for ’23/’24, we can reasonably hope for a <2 month timeline from approval to final NICE guidance.
