No, the trial remains blinded through crossover:

Here for example, though you can find this all over

If scans show that your tumour starts to grow again during treatment, you can start having DCVax-L injections regardless of the group you are in. This is called a ‘crossover option’. You may have already been having the vaccine, or you may have been having the dummy drug – neither you nor your doctor will know. If you go into the crossover option, you still won’t know which treatment you’d been having up until then. But you will definitely be having the vaccine from then on.

Arguably the term "crossover" is a poor term when applied to the treatment arm patents, "retreatment" makes more sense as they do restart the dosing schedule.

Regardless, is is still blinded.
