And as EVP came out, it looked so good.

BackTable Urology

They said, well, why don't we add EV, right?

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

And so the design of the trial was looking at just the EV arm.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

So it's EV PEMBRO conditions standard dosing for nine weeks, so three cycles.

BackTable Urology

followed by surgery, followed by six additional cycles of ED Pembro.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

And then there's a total of 17 cycles of Pembro in all, right?

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

So for a total of a year versus going right to surgery.

And so that was the design.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

I think as they went through, they allow patients to assist

cis-refusing, that was a minority of patients.

Starting out with, if you look at who is enrolled in trial, we haven't seen the paper yet, but these were sick patients, right?

BackTable Urology

Meeting age was in their mid-70s.

BackTable Urology

A majority of these patients had T3 diabetes.

disease, nearly all but 20 or 30% had poor renal function.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

I mean, these were the patients we see in the clinic, right?

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

These are the patients that come in.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

And what we saw is that there was an improvement

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

This leads to a significant improvement in both EFS and overall survival with addition of perioperative ED PEMRO versus surgery alone with a path CR rate, and depending on what you use as denominator patients who went to surgery or whatever, but it was well over 50%, which is unheard of.

BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor

We haven't seen that with even dose-dense and back.

in some of these trials.
