Is there emerging DLBCL research that you feel patients should know about?

Dr. Dean:

I would say, “yes.” One of the things that has really been striking for me in the last few years alone in caring for patients with large B-cell lymphoma is how we’ve gone from a more surface-level understanding as we’ve been talking about what some of the differences are between different cases of large B-cell lymphoma to being able to get a better readout of why the lymphomas sometimes behave the way they do.

I want to be careful to make sure that patients who might be listening to this understand that we still don’t have a crystal ball. We can’t review their biopsy, look at their scans, and tell you, “I know that if you get R-CHOP you’re going to be cured.” Or if they’re a high-risk situation we can’t look into a crystal ball and tell them, “I know that R-CHOP won’t work for you, and you should do this tougher, more intensive treatment.”

We still see a lot of outcomes that we can’t necessarily predict from those other kinds of tools. They just give us a better sense of what the odds are for people as we’re at the start trying to make decisions about what to do. Another element that has really been striking has been the introduction of engineered T-cell immune therapy, which has provided an option for cure for some patients that otherwise we wouldn’t have had an option, and worked for about half the patients that go through it overall.

What’s coming down the road in clinical trials that are still ongoing is information that’ll help us decide if that approach to treatment should move to being second in line instead of a stem cell transplant for some patients, and they’re even doing studies looking at whether, for very high-risk patients, adding a CAR T-cell treatment onto the end of initial chemotherapy leaves them better off in the long run.

So, those are questions that will take some time to answer with ongoing studies, but I think are really exciting because they’re taking advantage of some of these newer treatment approaches that we know are helping some patients when their first attempts at treatment didn’t work and seeing if they might leave them better off if we use them earlier in the process.

There are other studies ongoing looking at seeing if we can improve upon the results that we get with treatments like R-CHOP as the first pass at treatment. Many such studies have been done and have not shown any benefit by adding this drug or that to the standard R-CHOP treatment, but there have been a few new drugs approved for treating people with large B-cell lymphoma after it’s relapsed in the last few years. For example, one called polatuzumab vedotin. Another combination of the drug lenalidomide and a new antibody-based drug called tafasitamab.

And then there’s another drug called loncastuximab. So, there’re studies going on with all of those looking at whether they offer more benefits to patients if we use them earlier in the game.
