Are there new diffuse large B-cell lymphoma (DLBCL) treatment options? Dr. Kami Maddocks reviews developing research and approaches and what these advances could mean for patients.

Have there been any recent developments in how DLBCL is treated?
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.
Right. Combination approaches?
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.
Thanks, Dr. Maddocks. That’s really helpful information.
