The great thing about this story is the FACT that L works as is attested to by Fraunhofer’s claim that enrollment was done only to the point “statistically necessary”. Not my opinion, statement of fact not left open to interpretation based on regulator intervention which exwannabe has validated on numerous occasions. The only thing left is FORMAL validation which the PIP went a long ways towards doing along with the 5 year plus survivors in nGBM and rGBM waving at you. Now that really is a nice story!; ). Best wishes.
