It is at moments such as these, that it is good and salutary to remember that DCVax-l is perhaps the safest biotherapeutic cancer therapy, with a known mechanism of action that directs t-cell intra-tumoral infiltration — (beyond the blood-brain barrier) targeting (in coordination with other immune communications/activities) an incredibly broad spectrum of relevant cancer cells leading to increases in long term survival for a significant number of patients, and this was already followed by the MHRA for over ten years during their compassionate program observance.

(The three recently approved therapies likely took longer due to safety concerns, or proof of safety verification.)
