Sentiment Thank you for your elaborate view of the FDA's guidance on the use of external controls for clinical trials with individual patient-level data/ ECA's. Can you then please comment on why the American Brain Tumor Association seems to be more concerned about the FDA's proposal to require the inclusion of patient-level data in marketing applications than you are?
Thank you for replying

An FDA proposal to require the inclusion of patient-level data in marketing applications may prevent the use of external controls for some rare diseases, the American Brain Tumor Association said in their comment. “[I]ndividual patient-level data (IPD) is not always available for many cancers and other rare diseases,” they wrote. “This is due to many barriers that interfere with data sharing in healthcare.”
After consultation with the FDA, the company can conduct a hybrid registration trial that allows for the use of matched external controls for two-thirds of control arm
And from your own references (did you read them?):
9 that include (among other factors) a valid comparison to a control.
Numerous doctors have already come out showing why this is not the case with the P3 and the ECA. A non-starter unless the FDA is stacked with NWBO shills.
