Nilanjan Ghosh, MD, a hematologist and medical oncologist at the Levine Cancer Institute, Atrium Health, discusses the current unmet needs in mantle cell lymphoma (MCL) and how Bruton’s tyrosine kinase (BTK) inhibitors are being looked at to fill that need for patients with high-risk disease in the first line.

In patients with MCL, BTK inhibitors are used for relapsed/refractory disease. Ghosh says that the results are better if BTK inhibitors are used at treatment earlier in the disease course versus later. Patients with high-risk disease, such as those who have a 

 mutation, deletion, or those who have blastoid morphology, typically do poorly with standard treatments compared to patients with low-risk disease.

If you move BTK inhibitors to the frontline space, how does that compare with standard treatments in this patient population? Ghosh thinks this is an important question in the MCL setting. Trials are ongoing looking at that question for these patients. The PCYC 1143 trial (NCT03112174) is looking at ibrutinib (Imbruvica), a BTK inhibitor, and venetoclax (Venclexta) for high-risk patients, like those with 

 or older patients in the frontline setting. These are unmet needs in this disease landscape.

Exploring Unmet Needs and BTK Inhibitors in the MCL Population

Nilanjan Ghosh, MD, a hematologist and medical oncologist at the Levine Cancer Institute, Atrium Health, discusses the significance of the data from a pilot study of chimeric antigen receptor (CAR) T-cell therapy lisocabtagene maraleucel (liso-cel) as treatment of patients who are ineligible for second-line transplant with relapsed/refractory aggressive large B-cell non-Hodgkin lymphoma.

Ghosh says these findings are significant for this older patient population, which has been associated with a poorer prognosis. These patients tend to have highly refractory disease and are older, where the median age is 72 years and 85% of patients are 65 years or older.

The complete response rate in this pilot study was 56%, but long-term data are not yet available, says Ghosh. However, in this population of older, frail patients who tend to have organ dysfunction and other comorbidities, achieving a complete response is more meaningful than a partial response.

Thus far, the responses appear durable, and Ghosh says there may be rationale for moving this treatment to earlier lines. For patients who otherwise do not have any potentially long-term treatment or disease control options, this treatment is a promising option for the field. If the study continued to show similar results as it comes to completion, Ghosh concludes we will be on track to incorporate CAR T-cell therapy into this patient population.
