Objectives: We assessed real-world healthcare resource utilization (HRU) and costs among US patients with relapsed or refractory mantle cell lymphoma (R/R MCL) by line of therapy (LoT).
Methods: We selected patients from MarketScan® (1/1/2016-12/31/2020): ≥1 claims of MCL-indicated first line (1L) therapies, ≥1 diagnoses of MCL pre-index date (1L initiation date), ≥6-month continuous enrollment pre-index date, second line (2L) therapy initiation, ≥18 years old at 2L, and no clinical trial enrollment. Outcomes included time to next treatment (TTNT), all-cause HRU, and costs.
Results: The cohort (N = 142) was 77.5% male, aged 62 years (median). Sixty-six percent and 23% advanced to 3L and 4L+, respectively. Mean (median) TTNT was 9.7 (5.9), 9.3 (5.0), and 6.3 (4.2) months for 2L, 3L, and 4L+, respectively. Mean (median) per patient per month (PPPM) costs were $29,999 ($21,313), $29,352 ($20,033), and $30,633 ($23,662) for 2L, 3L, and 4L+, respectively. Among those who received Bruton tyrosine kinase inhibitors, mean (median) PPPM costs were $24,702 ($17,203), $31,801 ($20,363), and $36,710 ($25,899) for 2L, 3L, and 4L+, respectively.
Conclusions: During the period ending in 2020, patients relapsed frequently, incurring high HRU and costs across LoTs. More effective treatments with long-lasting remissions in R/R MCL may reduce healthcare burden.

Mantle cell lymphoma is a rare blood cancer of white blood cells. This type of cancer can be hard to treat, even with new treatments. In about 15% to 20% of people, the cancer will not get better or will come back within 2 years of starting treatment. When this happens, there are few good options for treatments that work. Using medical claims data, we looked at healthcare use and costs among US patients with mantle cell lymphoma that came back after treatment or did not respond to treatment. We found 142 patients who met the study criteria. Of these, 77.5% were men with a median age of 62 years. Sixty-six percent got a third of the treatment and 23% got a fourth treatment or more. The time until the next treatment was about 9–10 months for patients who got a second and third treatments.. It was about 6 months for people who got a fourth or more treatment. The average monthly cost of treatment was about $30,000 for those receiving a second or fourth or more treatment. It was slightly less for those who got a third treatment. For those who got Bruton’s tyrosine kinase inhibitors, the monthly costs went up with each treatment they needed. Overall, we found that during the study period, patients with mantle cell lymphoma worsened quickly, received multiple treatments, and had high costs of care. Better treatments that work longer are needed.
