Confirmation of the Efficacy and Safety of Lenalidomide Oral Monotherapy in Patients with Relapsed or Refractory Mantle-Cell Lymphoma: Results of An International Study (NHL-003)

Abstract Introduction: Mantle-cell lymphoma (MCL) is a type of B-cell non-Hodgkin lymphoma (NHL) that typically responds to initial chemo-immunotherapy, but with a relatively short duration of response (DR) and progression-free survival (PFS) when treated with conventional chemotherapy agents. Although the overall survival (OS) of MCL has improved, most patients are not cured and new agents are needed. A sub-analysis of a recent phase II trial (NHL-002) investigating the efficacy and safety of lenalidomide in patients with relapsed or refractory MCL, demonstrated a promising overall response rate (ORR) of 53% with a median DR of 11.9 months. A confirmatory international phase II trial (NHL-003) of single-agent lenalidomide was initiated for patients with relapsed/refractory aggressive NHL that had received at least one prior treatment and had measurable disease. In this report, we analyze the current results from the MCL patients enrolled in this trial. Methods: Patients with relapsed or refractory MCL and measurable disease ≥2 cm after at least 1 prior treatment regimen were eligible. Patients received 25 mg of lenalidomide orally once daily on days 1–21 of every 28-day cycle. Patients continued therapy until disease progression or toxicity. The 1999 IWLRC methodology was used to assess response and progression. Results: This report focuses on the 39 MCL patients that were enrolled and evaluable for response assessment. Median age was 66 (33–82) years and 29 (74%) patients were male. Median time from diagnosis to lenalidomide treatment was 3.4 (0.4–9) years. Patients had received a median of 3 (1–8) prior treatments, and 23% (9/39) of patients had received prior bortezomib treatment. The ORR with lenalidomide was 41% (16/39), including 13% (5/39) complete response (CR)/unconfirmed CR, and 28% (11/39) partial responses. Ten (26%) patients had stable disease. The most common grade 3 or 4 adverse events were neutropenia (51%) and thrombocytopenia (25%), anemia (13%), fatigue (10%) and febrile neutropenia (10%). Conclusion: These results confirm that lenalidomide oral monotherapy is effective in the treatment of patients with relapsed or refractory MCL, with manageable side effects.

8533 Background: Mantle cell lymphoma (MCL) is an aggressive form of non-Hodgkin lymphoma (NHL) with poor prognosis. The immunomodulatory agent lenalidomide shows consistent activity with tolerable safety in multiple phase II studies of relapsed/refractory aggressive NHL (NHL-002 and NHL-003) and MCL post-bortezomib (MCL-001). This pooled analysis further examined the efficacy and safety of single-agent lenalidomide in patients with relapsed/refractory MCL. Methods: Single-agent lenalidomide was given 25 mg/d PO on days 1-21 of 28-day cycles as tolerated for 52 weeks (NHL-002) or until disease progression (NHL-003 and MCL-001). All MCL patients received ≥1 prior treatment, including bortezomib in MCL-001. Efficacy data were examined by independent central review for MCL-001 and NHL-003 and by investigators for NHL-002. Results: 206 patients with relapsed/refractory MCL were studied. The median age was 67 y (range 33-84; 63% ≥65 y), 91% stage III/IV disease and 51% had received ≥4 prior regimens (76% prior bortezomib). Overall response rate (ORR) with lenalidomide was 32% (10% CR/CRu), with a median time to response of 2.1 months and median duration of response (DOR) of 16.6 months (not yet reached in patients with CR/CRu; Table). Kaplan-Meier estimates for median PFS and OS were 5.4 and 23.9 months, respectively. Mean daily dose of lenalidomide was 21 mg. Grade 3/4 AEs included neutropenia (44%), thrombocytopenia (29%), anemia (11%), and fatigue (7%). Other any-grade AEs included tumor flare reaction (7%), venous thromboembolic events (7%), and invasive second primary malignancies (3%). Conclusions: Lenalidomide produced rapid and durable responses in patients with relapsed/refractory MCL, and exhibited a predictable safety profile among 3 phase II studies of lenalidomide in heavily pretreated patients, including prior treatment with bortezomib.

Abstract Introduction: Mantle-cell lymphoma (MCL) is an aggressive B-cell lymphoma that if not cured with aggressive chemoimmunotherapy and stem cell transplant is usually fatal. The intravenous proteasome inhibitor bortezomib produces an overall response rate (ORR) of 33% in patients with relapsed MCL (J Clin Oncol2006;24(30):4867–74). Unfortunately, most patients eventually relapse and new agents are needed for this disease. Two recently conducted phase II trials (NHL-002 and NHL-003) tested single-agent lenalidomide for patients with relapsed MCL. Fifty-four patients with MCL were enrolled into the two studies; 26% (14/54) had received prior bortezomib and they are the subject of this report. Methods: Patients with relapsed or refractory MCL and measurable disease 2 cm after at least one prior treatment regimen including prior bortezomib were eligible. Patients received 25 mg of lenalidomide orally once daily on days 1–21 of every 28-day cycle. Therapy was continued as tolerated or until disease progression. The 1999 IWLRC methodology was used to assess response and progression. Results: The 14 patients in this study were heavily pretreated with a median of 4 (2–6) prior treatments (including bortezomib) and 50% were bortezomib-refractory. Median age was 66 (45–84) years and 6 (43%) patients were female. Median time from diagnosis to lenalidomide treatment was 3.3 (0.7–7.6) years. The ORR with lenalidomide was 57% (8/14), including 21% (3/14) complete response (CR)/unconfirmed CR and 36% (5/14) partial responses. One (7%) patient had stable disease. The most common grade 3 or 4 adverse events were neutropenia (50%), thrombocytopenia (43%), anemia (21%), fatigue (21%), and leukopenia (21%). Neutropenic fever occurred in 7% of patients. Conclusion: These results demonstrate that lenalidomide oral monotherapy is very effective with manageable side effects in patients with relapsed or refractory MCL who had received prior treatment with bortezomib.

Purpose Although dose-intensive strategies or high-dose therapy induction followed by autologous stem-cell transplantation have improved the outcome for patients with mantle-cell lymphoma (MCL), most eventually relapse and subsequently respond poorly to additional therapy. Bortezomib (in the United States) and temsirolimus (in Europe) are currently the only two treatments approved for relapsed disease. Lenalidomide is an immunomodulatory agent with proven tumoricidal and antiproliferative activity in MCL. The MCL-001 (EMERGE) trial is a global, multicenter phase II study examining the safety and efficacy of lenalidomide in patients who had relapsed or were refractory to bortezomib. Patients and Methods Lenalidomide 25 mg orally was administered on days 1 through 21 every 28 days until disease progression or intolerance. Primary end points were overall response rate (ORR) and duration of response (DOR); secondary end points included complete response (CR) rate, progression-free survival (PFS), overall survival (OS), and safety. Results In all, 134 patients were enrolled with a median age of 67 years and a median of four prior therapies (range, two to 10 prior therapies). The ORR was 28% (7.5% CR/CR unconfirmed) with rapid time to response (median, 2.2 months) and a median DOR of 16.6 months (95% CI, 7.7 to 26.7 months). Median PFS was 4.0 months (95% CI, 3.6 to 5.6 months), and median OS was 19.0 months (95% CI, 12.5 to 23.9 months). The most common grade 3 to 4 adverse events were neutropenia (43%), thrombocytopenia (28%), anemia (11%), pneumonia (8%), and fatigue (7%). Conclusion The MCL-001 study demonstrated durable efficacy of lenalidomide with a predictable safety profile in heavily pretreated patients with MCL who had all relapsed or progressed after or were refractory to bortezomib.
