RE:RE:RE:RE:3rd quarterIt's clearly not a concern as far as Roger is concerned.
"...it was a bit of a surprise for us that they insisted on central pathology. Because the concordance level of local pathology compared to central pathology is extremely high - 95 to 100%. I think when I was talking to Doctor Peter Black, who runs the UBC site, he did a study for monoclonal antibody, I think Atiza was the drug. And his concordance on his 120 patients was 100% across the board.
Why? Because in local pathology, you have board certified pathologists reviewing the data. They're experts in their field. You're now going to take the slides that they're looking at and give it to another board certified pathologist who also is an expert in their field. The amount of time that these two men or women disagree with each other is virtually zero because they wouldn't - they would say we don't have enough data or this is cancer or it's not. Because they're making decisions on patients' lives...whether you're cancer free and that's not a problem, or we think you've got cancer and you should have your bladder removed. Because there's a 12% morbidity and I think almost a 14% mortality risk from the surgery from radical cystectomy. So these decisions aren't made easily.
I think it was a bit of a weird ask because the concordance is extremely high. You can imagine if you go to your doctor and he says "yes, you have cancer", and you go to another guy and he says, "no, no, no, you're perfect". That's probably not going to happen.
So it was a bit of a weird ask, but they are the rulemakers. They're the judge, jury and executioner for where we want to go. Because the ultimate goal is FDA approval. Because you want access to the US market. They're the gatekeepers. So you're going to have to comply with what they say."

Since we don't know exactly why the FDA appears to have added that requirement mid-stream, I think it's a legit concern. Receiving BTD will relieve all those types of ambiguous concerns based on lack of info.
