NorthWest Biotherapeutics Inc (NWBO)

The one time they announced something prematurely it was an intent to file for approval with the UK, and then they had to revise their timing a couple times.

Really, the only time? How about:

Feb '24: Northwest Biotherapeutics Moves From Optimization of Flaskworks Prototype to Fabrication of GMP-Compliant Units For Installation, Validation and Final Testing Prior to Regulatory Certification
That morphed into doing more "optimizations" and then reverting to an earlier design and a year later waiting for clean rooms to be built (that had not been started).

April '20 W Bio To Discuss Projected Schedule For Data Lock, Unblinding and Top Line Data From Its Phase 3 Clinical Trial At Annual Shareholder MeetingBETHESDA, Md

ASCO 2019, Bosch announces 2 Direct trials to start in coming months
These were different from the new Direct trial Bosch hyped as Asco 2017. None ever launched. And before someone makes the usual "they had no money" excuse, the lack of cash was known when NWBO hyped the trials to be started.

And many other examples can be found.
