So the question now is, how do we treat up?

Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
Well, will be.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
Once we see the DV PEMBRO data, will be how do we treat up front, localize it,
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
locally advanced and metastatic patients who do have HER2 or, you know, at least one plus disease, depending on the results, how do we treat those patients when you have EV Pembro and other things?

Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
We're also going to see other, you know, there are other trials, the FORAGER, which is going to have the FGFR3 with EV Pembro up front.

So it'll be interesting to see how the upfront locally advanced and metastatic setting evolves over the next couple of years as well.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
Yeah.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
So as you both know, HER2 and Nectin-4 are usually co-expressed quite frequently.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
So that is an important question.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
At ASCO-GU, you will see some data from UNITE on EV-Pembro outcomes in patients with HER2-positive disease.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
So we'll see that probably in some real-world data.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
And then from there, that'll be the question once we see the DV-Pembro data is what to do.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
Yes.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
There's a subset for sure.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
There are still, you know, 10% of patients who do have primary progression, and we need to figure out who those patients are.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
And we'll be looking at, we're actually looking at that in UNITE as well.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
But ideally, we would get that data from a prospective clinical trial.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
The important thing is to identify those patients who are not going to respond to upfront Evpembro.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
And then those patients, I think, you know, we can't forget about these patients with the less common subtype histologies, like the micropapillary, the, you know, the nested variants, the squamous cell.
BackTable Urology
Ep. 287 Urothelial Carcinoma: Understanding CTDNA and Precision Medicine with Dr. Amanda Nizam and Dr. Brad McGregor
You know, we really need to start doing more trials in those populations.
