So this patient is asking, “When you are in the watch-and-wait phase and are feeling lymph nodes getting bigger, when is it appropriate to contact your oncologist?”

Dr. Jacobs:

This is a question that comes out a lot with my CLL patients. It’s a very subjective thing. Lymph node pain, that’s what’s supposed to trigger needing treatment for CLL from a lymph node standpoint. Technically speaking, if there’s a lymph node bigger than 10 centimeters, we’re supposed to start treatment. That’s one of the criteria too. That’s one that I almost never see, because usually patients get uncomfortable with their lymph nodes or their disease progresses elsewhere significantly before a lymph node gets that big.

So discomfort or pain, and that’s up to the patient, and I tell them like, “You have to tell me if this is bad enough that you want to start treatment.” And I have patients that are very different in how they interpret that. And I’ve got some patients that have visibly enlarged neck nodes and have had it for a while, and they don’t feel like they’re bothered by them, even though they’re quite chunky.

And then I have patients that have had lymph nodes that aren’t that big that really bother them. And so we start treatments. It’s just a very subjective thing. The only part I would identify is, you don’t need to just call your oncologist if you’re just noticing a little bit of growth or a node here and there, that’s expected. If you’re on active surveillance, it is expected that over time most patients’ white count will go up. Not all, most patients’ lymph nodes will grow. Not all.

The reason I would call an oncologist to maybe schedule earlier follow-up is if there’s accelerated growth that’s persistent and maybe if it’s associated with new symptoms like feeling really badly, fevers, waking up drenched in sweat. These are all signs that maybe the lymphoma has transformed to a more aggressive type of lymphoma that’s called Richter’s transformation. So that’s when I would be concerned. But low level chronic growth that’s relatively asymptomatic, is not overly concerning. 

Lisa Hatfield:

Hey, as a blood cancer patient, the limited duration treatment sounds like a dream. So this patient is asking, is there a time-limited pill-only treatment regimen yet, or is one in the pipeline?

Dr. Jacobs:

If you live in Europe, ibrutinib (Imbruvica) and venetoclax (Venclexta) got approved. I did a lot of research on that study. The FDA didn’t look as favorably on the comparison arms of the trials that led to the approval in the EU. So we do not have FDA approval. It is on the NCCN guidelines, as an option in…or as another option, that you can consider. The research is ongoing into getting the venetoclax combination approved with the newer BTK inhibitors. I currently am putting a lot of patients on a trial that’s looking at acalabrutinib and venetoclax. So I do think we will have, for some patients, the option, that for some patients that want it, and that seem to fit the, what we ultimately decide is the best patient population for this combination, the option to give a combination of pills for a time-defined period.

And then this patient is asking a pretty specific question, “Cancer patients are always worried about recurrence or worse, a second cancer. How can I be sure that my CLL doesn’t progress to something called Richter’s transformation?” So maybe if you can explain what that is, talk about that a little bit, the Richter transformation?

Dr. Ryan Jacobs:

Yeah. It’s a really aggressive transformation of the CLL into a high-grade B-cell lymphoma. It’s generally a situation where the cancer cell was a CLL cell and then becomes more aggressive and kind of becomes the dominant cancer, because it’s a lot more aggressive than the CLL. The CLL is still there, but then now you’ve got this aggressive lymphoma on top of it.

We are still treating it like we do other aggressive lymphomas in general. We are trying to find better ways to treat it, because these patients do not have good outcomes with standard lymphoma treatments. I’ve been having success recently for my patients that relapse after chemo, and the large majority of patients will relapse after chemo, but I’ve been having some recent success using CAR T in those patients, and also now have a, I was thankfully getting it sort of off-label approval to do that, but now I actually have a clinical trial investigating axicabtagene ciloleucel (Yescarta) in those patients.

So that’s one area where we’re looking, but we like to manage first-line treatment better. There’s going to be a couple of…I was looking at the big cancer meeting, ASCO is coming up, and that’s usually a meeting that’s much more focused on solid tumors, but there usually are a handful of lymphoma presentations. There wasn’t really much to get excited about, I would say, in terms of big presentations from specifically treatment of CLL, but there were a couple of oral presentations, big presentations for Richter. So that’s really great to see. It’s a very hard disease to do clinical trials in, because generally the patients present so aggressively that you just have to emergently start treatment, and putting patients on clinical trials takes a little extra time in most circumstances, so it’s so hard. But there’s, looks at more data with CAR T and Richter, so we’ll get some more information there, with specifically the Liso-Cel product, which is a different CAR T. And then there’s also looking at doing some immune-based therapies to treat relapsed Richter’s as well. That data hasn’t been released yet, so I’ll be interested when they put that data up preceding the presentations.

What Does Minimal Residual Disease (MRD) Mean for CLL Patients?

Katherine:

Sophia wants to know, “Are there any clinical trials regarding Richter’s, or DLBCL, transformation?” 

Dr. Bhat:

So, Richter’s transformation means when CLL, which is a low-grade disease, changes into high-grade lymphoma, and most commonly it’s “diffuse large B-cell lymphoma,” or DLBCL. Currently available treatments for Richter’s transformation are, unfortunately, sub-optimal. So, clinical trials to find better treatments are critical for this division, and there are a number of these currently going on. For example, some trials add targeted agents to the backbone of standard chemotherapy called, “R-CHOP.” 

So, we have one trial where acalabrutinib is being added. There’s another clinical trial where venetoclax is being combined with R-CHOP. One of the problems with Richter’s transformation is that it tends to be refractory to treatment, and it tends to come back or relapse. So, there are studies ongoing for relapse treatment as well, with combination of targeted agents. And CAR-T therapy, we just talked about that, is also being studied in Richter’s transformation. So, there’s a lot going on to improve the outcome for this.
