Katherine:                  

Yeah. You touched upon this earlier, Dr. Westin, but aren’t there emerging DLBCL approaches the patient should know about?

Dr. Westin:                 

Yes. Thankfully, there are many, many. We could spend several hours talking about lots of new therapies coming along. So, it’s a great answer to have. It’s an embarrassment of riches that we have for lots and lots of new therapies that appear quite promising in the early development stage.

In terms of those that have actually crossed over the finished line to be approved by the FDA, we have a handful of new therapies in the past few years that have been approved. Previously, we didn’t really have very many, but now there are multiple therapies that are approved by the FDA outside of a clinical trial, that are targeted treatments.

And those include antibody drug conjugates, basically an antibody like you make against an infection. However, this antibody has a chemotherapy warhead attached to the back of it. So, effectively, it’s a heatseeking missile that finds whatever target we want it to find – in this case, cancer cells – and delivers a high dose chemotherapy right to the bad guys, not to the good guys. There are also other immune therapies that we’ve seen than can be very powerful antibodies, plus immunomodulatory drugs. And we can talk about specific names of these if we’d like.

And then, lastly, there are other oral agents that are coming along that look very promising in terms of their ability to target the cancer cells more directly than growing cells.

Lastly, there’s a very new class of therapies not yet approved, but very promising. I mentioned this before. It’s something called a bispecific antibody. Bispecific – the word bicycle meaning two wheels. Bispecific is two specific antibodies. Basically, it’s an antibody that’s grabbing onto a cancer cell and grabbing onto an immune cell. “I’d like to introduce you guys. Why don’t you guys come in proximity and see if we can have a party.”

And it’s an idea here of trying to get the cancer cell to be attacked by the immune cell simply through this close proximity that occurs. Not yet approved. Looks very promising and I think probably will be approved for multiple different lymphoma types, including large B-cell, in the coming years.

Understanding Common Bladder Cancer Treatment Side Effects

Katherine:                  

I imagine side effects vary among patients. What side effects should someone undergoing treatment be aware of?

Dr. Gupta:                  

Yeah, and that also depends on what kind of treatment they’re getting, Katherine. So, if somebody’s getting chemotherapy, some of the usual chemotherapy related side effects.

Again, it depends on what chemotherapy they are getting, but usually it’s nausea, vomiting, peripheral neuropathy, hair loss, low count, so we try to prevent their counts from going down to prevent infection. If they’re undergoing a local therapy like BCG, they may get irritation in the bladder, something called urinary tract infections can happen, or just an inflammatory state.

Immunotherapy is not as hard as chemotherapy, any day it’s easier but it can cause some rare and infrequent side effects because the immune system can turn against other organs which can sometimes be life threatening or fatal. That could be inflammation of the lung, of the colon, of the different organs in the brain, of the thyroid gland, of muscles, of heart. It can be pretty much anything. We educate the patients accordingly for that.

And, as far as the newer antibody drug conjugates are concerned, they can cause neuropathy or low counts, hair loss. So, every treatment depending on what treatment we’re choosing has a different treatment side – related toxicity profile and we go about reducing or modifying doses as we go along treating the patient.

Katherine:

When it comes to metastatic breast cancer research and emerging treatment options, what are you excited about specifically?

Dr. Sammons:

That’s a really good question. I think, right now, I’m very interested in a class of drugs called antibody drug conjugates.

What antibody drug conjugates are – they take a monoclonal antibody, which is – most patients have heard of Herceptin. So, Herceptin is an antibody which goes in and targets HER2. But that antibody is actually linked to a payload of chemotherapy cells. But instead of just – regular chemotherapy we inject that chemotherapy into the veins, it goes all throughout the body, it can be fairly toxic.

Antibody drug conjugates specifically find the cells that have that biomarker, like HER2, or TROP2, or HER3, and they find that cell, and they don’t release their chemotherapy until they’re taken up by that cell. So, it’s more a targeted, focused chemotherapy.

There is an antibody drug conjugate in HER2-positive breast cancer called Enhertu, or trastuzumab deruxtecan, which is – has been shown to have excellent efficacy in very heavily pre-treated HER2-postitive breast cancer.

It’s moving into earlier lines of therapy. The drug is so effective in HER2-positive breast cancer, we’re also looking at it in something called HER2-low breast cancer. So, breast cancers that we never thought before would respond to HER2 targeted therapy is – it appears that even if they express a little of HER2, this drug might have efficacy. So, that’s in clinical trials, and that’s really exciting.

What’s also great, is about 60 percent of women with hormone receptor-positive breast cancer are HER2-low. So, that could be a really great drug option in the future for those patients.

There’s another antibody drug conjugate called sacituzumab govitecan, which is approved in triple-negative breast cancer, and was shown to improve overall survival, which you always want at the end of the day – a drug that is well-tolerated and helps patients live longer.

That drug is approved in triple-negative breast cancer, but we’re now looking at it in hormone receptor-positive breast cancer.

There are also a variety of other antibody drug conjugates in clinical trials. One that’s looking at HER3, a few others that are looking at HER2, and also TROP2.

So, I’m definitely excited about antibody drug conjugates.

I’m also very excited about the field of immunotherapy in general. Immunotherapy has sort of lagged behind in breast cancer compared to some other tumor types like lung cancer and melanoma. But in triple-negative breast cancer, we finally have approval for two types of immunotherapy, but only if they have a certain biomarker.

Right now, immunotherapy only helps patients with metastatic triple-negative breast cancer if they express something called PDL1. So, we have FDA approval for two different immunotherapies for PDL1-positive triple-negative breast cancer. And there are many different strategies ongoing in clinical trials with different types of immunotherapy that try to harness the patient’s immune system to fight the cancer, instead of just giving regular chemotherapy. It’s really trying to help the patient’s immune response help fight the cancer.
