Yes, I believe that the EU (UK & Germany) was the last to approve the revised SAP & endpoints. The EU clinical trial registry is updated by the EMA. I found the updated EU clinical trial registry, with the 6 revised endpoints on 10/8/2020, and I posted it to this message board. The data lock was announced by NWBio on 10/5/2020, just 3 days earlier.

I believe that after NWBio received a verbal or written confirmation of their SAP buy-in from the EMA & MHRA, NWBio issued their data lock PR on 10/5/2020. It only took the EMA clerical staff 3 calendar days or less to update the EU clinical trial registry.

The DCVax-L Phase III trial started in the US in 2007. The FDA had to approve the original trial protocol, and the original endpoints. If I remember correctly, the trial only started with about 50 trial sites, all in the US. The EU trial sites in the UK and Germany were not added until starting around 2012:

The FDA is the lead / governing RA. It approved the first trial protocol and SAP, and it should be the first to approve the revised SAP. Since 2018, the FDA has been the leading RA that is promoting & advising clinical trial sponsors to include Real World Evidence (RWE) and Real World Data (RWD) in their analysis of safety & efficacy for approvals of new drugs or biologics. Take a look at this guidance from the FDA about using external contemporaneous external control groups in clinical trial data analysis:
