What is targeted therapy, and how does it work to treat bladder cancer?  

Dr. Anari:

So, targeted therapy is really a newer, more tailored approach to treating certain types of bladder cancer. Targeted treatments because they’re targeted have most of their effect on the cancer cells. Although, obviously, there’s other potential side effects. But the way it works to treat bladder cancer really depends on the different types. There are several different targeted treatments out there.   

Often, targeted treatments are approved for people after they’ve gotten chemotherapy and/or immunotherapy for their bladder cancer treatments. There are several different ones out there. Erdafitinib is one of them. It’s a pill. It’s approved for patients who have an FGFR alteration.  

Well, what is that? It’s something that your doctor finds by getting the DNA or genetic makeup of your cancer cells. So, those pills are available to people with that certain alteration that’s found on special testing. 

With these pills, potential side effects – we talked about how the effects are mostly on the cancer cells. But there are other side effects that we have to keep in mind. This drug in particular can have different eye disorders. So, we work closely with ophthalmologists.  

And then we check blood work because people can have high phosphate levels in the blood. Phosphate levels can be controlled often with diet, sometimes with medications, and sometimes with just adjusting the dose of the pill itself.  

Katherine Banwell:

You mentioned the FGFR genetic alteration. Should bladder cancer patients undergo molecular testing?  

Dr. Anari:

So, the most common place where we do that is when people have metastatic bladder cancer. It’s a good idea to test the biopsy sample or bladder cancer sample that’s already been removed.  

That way we get this information. While it doesn’t always change the up-front treatment for bladder cancer, it is really important to know really what tools in our toolbox we have for the treatment of bladder cancer.

Katherine:                  

So, Dr. Gupta, are there emerging approaches for treating bladder cancer that patients should know about?

Dr. Gupta:                  

Yes, absolutely. I would say that the field is so rife with so many different treatment approaches and ways to offer more personalized medicine. We know, for example chemotherapy followed by surgery has been the gold standard, but we have seen data that there are certain genes in some patients’ tumors which may predict how well they will respond and potentially we could avoid a life-changing surgery like cystectomy.

And we have trials with immunotherapy adding to chemotherapy in bladder preservation approaches along with radiation. So, these are some of the new work that’s been done. Approaches to intensify the effect of BCG in newly diagnosed non-muscle invasive bladder cancer patients are also ongoing. Then, in the metastatic setting, we have so many treatment options that have become approved in the last couple of years, now the goal is, well, how to sequence the therapies best for the patient and whether in the front-line therapy we can actually get rid of chemotherapy.

Some of these antibody drug conjugates and immunotherapy combinations are proving to be very effective and the hope is that one day patients may not need chemotherapy because we have chemo-sparing regimens. So, there’s a lot going on and I think the progress has been tremendous in the past few years.                                            

Katherine:                  

Some patients may be fearful when it comes to clinical trials. So, what would you say to someone who might be hesitant to consider participating in one? 

Dr. Gupta:                  

I would say there’s a lot of misconceptions out there that going on a trial is like being a guinea pig or you get a placebo. For the most part, patients are getting active drugs whenever possible. The only time where we have placebo-controlled trials is if, for that particular setting, there is no approved treatment. But I think patients should get all the information from their doctors and the study teams about the pros and cons.

Many times, it’s about – you could do the study because the patients meet the criteria and are fit to do it and if they wait for later, they may not be eligible anymore for whatever reasons.

I always put it this way, that standard of care therapies will still be available, but studies are sometimes with a tight window and tight criteria. So, I think patients should know that all these studies that are out there are very ethical and use the best possible control arm. So that even if they don’t get that experimental drug, they still get what is the standard of care unless it is something really being compared to nothing.

Katherine:                  

You’ve touched upon treatment options but let’s walk through the treatment approaches for bladder cancer and who they might be right for, and I’d like to start with surgery. Who would be a good candidate for surgery?

Dr. Gupta:                  

I think patients who are otherwise fit, that is, they have good performance status, don’t have a lot of cardiac or other comorbidities, are not very obese, and of course have to be fit for any major procedure are usually considered good surgical candidates. But, as far as – In terms of staging, the patients with stage I, if BCG does not work in them or immunotherapy doesn’t work, they are recommended surgery if they are good candidates.

If they are not good candidates, we then – our role as medical oncologists is to offer other systemic therapies. As far as stage II cancer is concerned, the gold standard has been chemotherapy, followed by surgery but that’s the gold standard.

It may not apply for every patient. Depending on how fit patients are. Are they – we don’t usually just go by their chronological age but how fit they are? What are their comorbidities? If surgery is going to be a big burden for them moving forward, then we do talk about radiation and chemotherapy and other bladder preservation approaches.

Katherine:                  

What about immunotherapy and targeted therapies? Who would you use those on?

Dr. Gupta:                  

Well, since the advent of immunotherapies back in 2016 they’ve really – we’ve made a lot of progress and changed the way treat bladder cancer and the overall survival has improved by leaps and bounds with all these drugs.

Immunotherapy now plays a role in different stages. It is approved for superficial or non-muscle invasive bladder cancer if, let’s say, BCG doesn’t work. In muscle invasive disease we have along with others shown that immunotherapy is safe and effective, although it is not yet FDA approved, so there is a lot of clinical trials going on to prove its superiority in combination and by itself.                                   

And, in metastatic disease or locally advanced disease immunotherapy plays a huge role for patients who have either disease recurrence after chemotherapy or are not good candidates for any chemotherapy.

I would say that immunotherapy is a very big – plays a very big role in the treatment. Unfortunately, not everybody responds to immunotherapy only about 20 to 25 percent of patients do.

 That’s why we have these other novel therapies that have been coming through, like antibody drug conjugates, namely enfortumab vedotin, sacituzumab govitecan, and targeted therapy in the form of an FGFR inhibitor was the first targeted therapy that was approved a couple of years ago for patients who have a mutation in their tumors.

That’s really personalized medicine for those patients.

Katherine:                  

Right. What about biomarker testing? Does the presence of certain biomarkers impact certain treatment options?

Dr. Gupta:                  

That’s a great question and we’re all striving to find the perfect biomarker in bladder cancer. In the past we thought that expression of PD-L1 in the tumor cells and immune cells is a marker of how well the immunotherapy will work, but we have learned over the past couple of years that biomarker has turned out to be quite useless.

We don’t really need that to guide our treatment. We’re still depending on clinical biomarkers for immunotherapy use or chemotherapy use. I would say that the biomarker question is still being looked at and eventually I would say it’s not going to be one biomarker, but a composite of several different biomarkers that we will be able to use comprehensively.
