Lisa Hatfield:

Dr. Shah, can you speak to some promising treatments that are available now for DLBCL patients? 

Dr. Nirav N. Shah:

Yeah, so while we consider DLBCL to be one disease, there is a lot of heterogeneity in it, and so there are sort of subtypes of DLBCL that we approach differently. And so the most well-known standard of care for DLBCL is a chemotherapy regimen called R-CHOP. It’s a five-drug regimen, it’s given once every three weeks for up to six cycles, again, depending on the stage, the presentation that the patient is in.

However, the goal has always been to do better than R-CHOP and there is an exciting new regimen called pola-R-CHP which gives you a drug called polatuzumab (Polivy) in lieu of an older drug called vincristine (Vincasar PFS), which is part of the R-CHOP regimen, and that regimen was tested head-to-head against R-CHOP chemotherapy and did have a slight improvement about a benefit of 5 percent to 6 percent in terms of its ability to induce a long-term remission, and again, that number may sound small, but every patient matters, and so that regimen, some of us have started adapting that, although I will note that that regimen is currently not FDA-approved, and so its accessibility and availability may be limited, although I’m optimistic that this regimen will be approved and become an option for the frontline for patients to come.

There are some types of diffuse large B-cell lymphoma that are a little bit more aggressive, we call some of these double-hit lymphomas, so a term that you may hear if you’re diagnosed and it’s something a doctor may talk about, and so for those patients, we often use a higher intensive regimen, the regimen that we use at our institution is a regimen called dose-adjusted EPOCH and so you can see here that it’s a little bit complicated, there are caveats here, there’s different treatment options available, and the number of treatments we give is partially based on how you present and the stage that you initially show up with. And so I think that it’s important to have a conversation with your physician. And so my activation tip for patients is to understand their stage of disease and review the treatment options available for that stage and subtype of diffuse large B-cell lymphoma to best optimize the regimen to each individual patient.

What treatment options are available for DLBCL patients?

Dr. Mehta:

So, it’s a very loaded question because, you know, front-line and relapse and field has evolved immensely over a period of years. But I’ll tell you that in a new diagnosis of DLBCL, still R-CHOP or R-EPOCH-based treatments are standard of care. We have – as a medical community, we have tried multiple times to improve upon the foundation of R-CHOP or R-EPOCH. But we have failed, unfortunately, that R-CHOP is still the best treatment.

There are multiple clinical trials, which are building on R-CHOP adding novel agents and see whether it gets better or not. So, therefore, when we discuss, we discuss always to ask about whether there is any clinical trial option. If the DLBCL comes back, which happens in about 30 to 40 percent of cases, there are so many treatment options.

There are novel options including bone marrow transplant. The CAR-T treatment, tafasitamab (Monjuvi), different CD19-directed therapies, or loncastuximab (Zynlonta) CD19-directed antibody drug conjugate. There are so many – polatuzumab (Polivy) – options available. Therefore, it is important to have a discussion with your provider that “Okay. Well, if it has come back, of course, it is disappointing. But what are my options, clinical trial options, novel therapeutic options,” so that we can work as a team with betterment and hoping to cure even if it has come back, a large cell lymphoma.

So, there are so many treatment options out there. I did not touch upon the clinical trial. There are so many clinical trials going on within amazing agents, which are very effective in DLBCL.

Katherine:

How are DLBCL patients monitored after treatment is completed?

Dr. Mehta:

Very importantly, if you go in remission and after the initial treatment or in a relapse setting, we have to keep an eye. And, of course, we want to detect if it comes earlier so that we can start the treatment earlier. Typically, in the beginning, in the initial two years, the follow-up could be closer, every four to six months we get together.

We have labs done. Sometimes we do scans, making sure that a lymphoma – there is no evidence of it coming back. So, the initial two to three years the follow could be closer. And then, as we space out, the follow spaces out further. And then, after you have a five-year mark where the lymphoma has not come back, the chance of it coming back goes further down. So, then I start follow-up annually on those patients. Yeah.

Katherine:

Have there been any recent developments in how DLBCL is treated?  

Dr. Maddocks:

There had been recent developments. So, the CAR T-cell therapy, there is now three approved options for patients. And so, even patients who maybe are older and not considered candidates for a stem cell transplant because of other medical factors, might be able to get the CAR T-cell therapy. This is now, again, approved in the second line. There are a couple antibody drug conjugates, polatuzumab and loncastuximab, they target proteins called CD-79 and CD-19.  

And the polatuzumab’s the one that probably is going to be available for part of the front-line treatment in the future. There’s the antibody tafasitamab and lenalidomide. These are all approved therapies in the relapse setting. There are also therapies that are being studied and showing promising activity, which we think are probably likely to be approved in the future. There’s something particularly called bi-specific antibodies.  

So, this targets a protein on the tumor cell but also a protein on the T cell. So, remember I said the T cells aren’t functioning. So, this targets the protein on the lymphoma cell but then targets a protein on the T cell to engage it to attack the lymphoma cell. 

Katherine:

Right. Combination approaches?   

Dr. Maddocks:

Yeah. So, there are a number of combination approaches under study a lot of the therapies that I mentioned, like the bi-specific antibodies, the antibody drug conjugates. These are all therapies that – they have side effects – I hate to say they’re well-tolerated – they have side effects but their side effects are such that they can be combined with other agents, that have different toxicities that are combined with each other. And so, there’s a lot of ongoing trials looking at combining these. There’re also oral targeted therapies that target proteins that are known to help the lymphoma cells survive and these are modulator therapies, BTK inhibitors, other inhibitors, that are being evaluated and used in combinations.  

Katherine:

Thanks, Dr. Maddocks. That’s really helpful information.

Katherine:

Dr. Nastoupil, now that we’ve discussed factors that go into the treatment choices, can you walk us through the currently available DLBCL treatment approaches and who they might be right for?

Dr. Nastoupil:

Absolutely. So, again, this is changing, and that’s good news. So, up until recently, R-CHOP or rituximab in combination with CHOP, which is an acronym for four different drugs, cyclophosphamide, doxorubicin, vincristine, and prednisone, has been our standard.

Again, what would potentially challenge that is the POLARIX study where we exchange vincristine for polatuzumab. We don’t know the results of that study yet. All we know is that it met its primary endpoint, meaning it met what it set out to do in terms of improving upon some of the outcomes achieved with R-CHOP.

We need to see the details to know if that means now every newly diagnosed diffuse large B-cell lymphoma patient will be offered the polatuzumab in combination with R-CHP study or whether or not there will still be some patients appropriate for R-CHOP.

But that is generally our first approach. Whether you get six cycles or a shortened course plus/minus radiation depends on your state. Once patients have completed therapy, generally, then we pursue what’s called surveillance.

So, we’re monitoring for any signs that the lymphoma has recurred or has not gone away. That’s a controversial topic in terms of how to conduct surveillance and one that I suspect will change over time. But for most patients, if the lymphoma is going to recur, it generally recurs within the first two years.

So, assessing patients either in the form of a CT scan, a PET CT, or a physical exam with labs every four to six months for the first two years is what most practices will pursue. I’m not saying that there is no chance that you would relapse beyond two years. It’s just that the majority of patients, at least 90 percent, if the lymphoma comes back, it usually does so within two years.

And the relapses that occur beyond two years are less predictable. They could happen at three years. They could happen at 10 years, as it’s hard to know how to do surveillance beyond two years.

If the lymphoma recurs, the first thing we need to do is biopsy it because there are many things that can mimic lymphoma on a scan – infection, inflammation, other tumor types. So, if there is ever a question about whether or not the lymphoma has recurred, I generally advise for all patients they undergo a biopsy to ensure that we know what we’re treating.

Depending on when the lymphoma recurs, if it happens within 12 months, this is another area that we are shifting our practice. In the past, for all patients who had relapsed large cell lymphoma, we would pursue what we call salvage or second-line chemotherapy. So, we mix up the chemo. We keep, generally, the rituximab, but we alter the chemotherapy agents. We wouldn’t give CHOP again.

And then we give a shortened course where we give two to three cycles. We repeat the scan. And for patients who’ve achieved what we call chemo-sensitive disease – so, that’s generally a complete response on scan – we would then move forward with high-dose therapy and an autologous stem cell transplant. So, essentially giving different but more intense chemo and rescuing patients from that maneuver with their own stem cells that will go back to the bone marrow and start making white blood cells, red cells, and platelets again.

What has shifted in the last six months is we now know that CAR T-cell therapy is superior to that approach, at least with two CAR Ts for patients whose lymphoma came back within 12 months. Again, we’re eagerly awaiting the full results of those randomized studies. But three trials were conducted. Two of the three suggest CAR T is better than second chemo and transplant for those patients who relapse within 12 months.

So, currently, we think that you’ll have a CHOP-like therapy with plus rituximab frontline. If you progress within 12 months, you potentially would be a candidate for CAR T-cell therapy. If the CAR T-cell therapy fails, which is true for about half of patients. Or if you’re deemed to not be a candidate for CAR T, we have several other new options that didn’t exist a year ago, including targeted or non-chemotherapy options.

So, there are at least four options in that setting now that are therapies that target the lymphoma cells, either by targeting CD19, which is another surface marker, augmenting that either with an antibody drug conjugate, such as loncastuximab tesirine (Lonca), or with an immune therapy, such as lenalidomide (Revlimid) and tafasitamab. Polatuzumab (Polivy) is available in that third line or later space combined with bendamustine (Treanda) and rituximab (Rituxan). There’s an oral agent called Selinexor (Xpovio).

So, a lot of that is not to burden patients with information but to let them know they’ve got lots of options. And many of these can be sequenced. So, if we can’t achieve cure with R-CHOP and/or CAR T, there are still very good outcomes in that third line or later space.
