Final results of a phase 3 trial suggest bortezomib plus rituximab and chemotherapy can significantly improve overall survival (OS) in transplant-ineligible patients with newly diagnosed mantle cell lymphoma (MCL).

In the LYM-3002 trial, researchers compared bortezomib plus rituximab, cyclophosphamide, doxorubicin, and prednisone (VR-CAP) to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).

The median OS was significantly longer in patients who received VR-CAP than in those who received R-CHOP—90.7 months and 55.7 months, respectively.

This survival benefit was observed in patients with low- and intermediate-risk disease but not high-risk disease.

Tadeusz Robak, MD, of the Medical University of Lodz in Poland, and his colleagues reported these results in The Lancet Oncology alongside a related commentary.

The LYM-3002 trial began more than a decade ago, and initial results were published in 2015. At that time, the VR-CAP group showed a significant increase in progression-free survival compared with the R-CHOP group.

The final analysis of LYM-3002 included 268 of the original 487 MCL patients. Twenty-three percent of patients in the VR-CAP group (n=32) discontinued due to death, as did 40% of patients in the R-CHOP group (n=51). The main cause of death was progression—29% and 14%, respectively.

Among the 268 patients in the final analysis, 140 belonged to the VR-CAP group and 128 to the R-CHOP group. The patients’ median age was 66 (range, 26-83), 71% (n=190) were male, 74% (n=199) had stage IV disease, and 31% were classified as high risk based on the MCL-specific International Prognostic Index (MIPI).

About half of patients received therapies after the trial interventions (n=255, 52%)—43% (n=104) in the VR-CAP group and 62% (n=151) in the R-CHOP group. Most patients received subsequent antineoplastic therapy—77% (n=80) and 81% (n=123), respectively—and more than half received rituximab as second-line therapy—53% (n=55) and 59% (n=89), respectively.

Results

At a median follow-up of 82.0 months, the median OS was significantly longer in the VR-CAP group than in the R-CHOP group—90.7 months (95% CI, 71.4 to not estimable) and 55.7 months (95% CI, 47.2 to 68.9), respectively (hazard ratio [HR]=0.66 [95% CI, 0.51–0.85]; P=0.001).

The 4-year OS was 67.3% in the VR-CAP group and 54.3% in the R-CHOP group. The 6-year OS was 56.6% and 42.0%, respectively.

The researchers noted that VR-CAP was associated with significantly improved OS among patients in the low-risk and intermediate-risk MIPI categories but not in the high-risk category.

In the low-risk cohort, the median OS was 81.7 months in the R-CHOP group and not estimable in the VR-CAP group (HR=0.54 [95% CI, 0.30–0.95]; P≤0.05).

In the intermediate-risk cohort, the median OS was 62.2 months in the R-CHOP group and not estimable in the VR-CAP group (HR=0.55 [95% CI, 0.36–0.85]; P≤0.01).

In the high-risk cohort, the median OS was 37.1 months in the R-CHOP group and 30.4 months in the VR-CAP group (HR=1.02 [95% CI, 0.69–1.50]).

The researchers reported three new adverse events in the final analysis—grade 4 lung adenocarcinoma and grade 4 gastric cancer in the VR-CAP group as well as grade 2 pneumonia in the R-CHOP group.

The team acknowledged that a key limitation of this study was that rituximab was not given as maintenance since it was not considered standard care at the time of study initiation.

Moving forward, Dr. Robak and his colleagues recommend that bortezomib be investigated in combination with newer targeted therapies in order to establish best practice for treating MCL.

The LYM-3002 study was sponsored by Janssen Research & Development. The study authors reported financial ties to Janssen, Celgene, Ipsen, Johnson & Johnson, Novartis, and other companies.
