Abstract Background: A previous trial of 2-CDA as a single agent for therapy of mantle cell lymphoma demonstrated this agent to be efficacious with an overall response rate of 81% (31% complete responses) (Blood 1999 Nov 15; 94:660a). A phase II study of the addition of rituximab to 2-CDA was conducted by the North Central Cancer Treatment Group based on improved outcomes achieved by the addition of rituximab to other regimens active in MCL. Methods: This one-stage phase II study was designed to determine the complete response (CR) or complete response/unconfirmed (CRu) rate. Central pathology confirmation of cyclin D1 positive mantle cell lymphoma was required. No previous therapy for lymphoma was allowed, with the exception of splenectomy. The schedule was rituximab 375 mg/m2 IV day 1; 2-CDA 5 mg/m2/d IV days 1–5 of a 4-week cycle. After 2 of the first 6 patients developed grade 4 neutropenia, subsequent patients received either pegfilgrastim or filgrastim support. Patients received 2–6 cycles of therapy, depending on response. Patients were required to achieve at least a PR after 2 cycles of therapy to continue on protocol therapy. Results: Patient characteristics of all 29 eligible pts: median age: 70 (range: 41–86); 21 male, 8 female; PS 0 (55.2%), PS 1 (41.4%), PS 2 (3.5%); stage II (6.9%), stage III (3.5%), stage IV (89.7%); prior splenectomy (20.7%). The only grade 4 adverse events occurring more than once were neutropenia (24.1%) and leucopenia (6.9%). One patient died of cerebral ischemia in the setting of pneumonia without neutropenia. Fifteen (51.7%; 95% CI: 32.5–70.6%) pts achieved a CR; only one has relapsed to date (665 days after starting therapy). Four additional pts achieved a PR. Ten pts have progressed with 4 pts progressing early at 17, 45, 46, and 71 days (two of whom have died). Ten pts (34.0%) went on to receive further therapy off study, 5 in less than a PR after 2 cycles, 2 in PR after study therapy, and 1 who went off study for a rash. Fourteen pts (48.3%) have progressed or gone on to receive additional therapy off study. At last contact, 26 (89.7%) were alive (median follow-up 14.3 months; range: 6–34). One year survival rate is 89.3% (95% CI: 78.5–100). Conclusions: Rituximab and cladribine were well tolerated for the treatment of MCL in a group of elderly patients. The response rate may have been underestimated due to the study design, which required at least a PR after 2 cycles to continue therapy. Despite this, 52% achieved a complete remission. Complete remissions attained with this regimen appear to be durable, with a single relapse to date among 15 patients achieving CR.

Abstract Abstract 1661 Poster Board I-687 Introduction One approach to improving outcomes in Mantle Cell Lymphoma (MCL) is to incorporate newer targeted agents into standard chemotherapy regimens. As the proteasome inhibitor bortezomib (Velcade‘) achieved a 33% response rate in relapsed MCL, we hypothesized that the incorporation of Velcade (Vc) into a modified R-hyperCVAD chemotherapy backbone would result in a high complete response rate (CR). The new regimen, VcR-CVAD, was tested for safety and efficacy in a phase II study within the Wisconsin Oncology Network (UW) and demonstrated a CR rate of 77% (Kahl, ASH 2008). To determine the safety and efficacy of this regimen in a cooperative group setting, we initiated E1405: a phase II study of VcR-CVAD with maintenance rituximab (MR) for untreated MCL. Methods Eligible patients had histologically confirmed, previously untreated MCL, PS 0-2, and adequate end organ function. The treatment plan included: Velcade 1.3 mg/m2 days 1 and 4, rituximab 375 mg/m2 IV day 1, cyclophosphamide 300 mg/m2 IV over 3 hrs q 12 hrs X 6 doses days 1-3, doxorubicin 50 mg/m2 continuous infusion over 48 hrs days 1-2, vincristine 1 mg IV day 3, dexamethasone 40 mg po days 1-4. Cycles were repeated every 21 days for 6 cycles and all patients received G-CSF support. Patients achieving SD, PR, or CR received MR administered as 4 weekly treatments every 6 months for 2 years (protocol therapy). Patients had an option to receive high dose chemotherapy and autologous stem cell transplantation (off protocol) rather than MR. The primary endpoint of the trial was the CR rate, incorporating PET imaging, to VcR-CVAD induction therapy. Results Seventy-six eligible patients were enrolled between 5/07 and 10/08. Baseline characteristics include median age 62 (40-76), 59M:17F, 91% stage III/IV, and 39% with elevated LDH. Sixty-four patients (84%) completed VcR-CVAD induction therapy. Reasons for treatment discontinuation included PD (1), toxicity (4), patient preference (2), and other/unknown (5). Response information is available on 74 patients while data is outstanding on 2 patients. The ORR was 96% (73/76; 95% CI, 89%-99%), CR rate 75% (57/76; 95% CI, 64%-84%) and the PR rate 21% (16/76; 95% CI, 13%-32%). Six of the PR patients were coded as such because of protocol violations in which a post-treatment bone marrow biopsy or PET scan was not obtained. The CR rate in the 68 completely restaged patients was 84%. Forty-four patients proceeded to planned MR while 21 patients went off protocol to SCT consolidation. Median follow up is currently too short (9 months) to assess PFS and OS. The major toxicity of the treatment regimen was expected myelosuppression. Grade 3-4 non hematologic toxicities were rare. No patients developed grade 3-4 neuropathy. There were no treatment related deaths. Conclusion The VcR-CVAD induction produced high overall response (96%) and CR rate (75%) in a representative MCL patient population treated on a cooperative group protocol. The CR rate was high and comparable to the UW pilot study (77%). No episodes of severe painful peripheral neuropathy were reported using the reduced vincristine dosage and the overall toxicity profile was very acceptable. Longer follow up is needed to determine if the high CR rate will translate into improved PFS and OS.

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.

Abstract The proteasome inhibitor bortezomib is FDA approved for use in Multiple Myeloma and has shown promising single agent activity in patients with relapsed Mantle Cell Lymphoma (MCL), of whom 30–50% respond. We initiated a phase II study investigating the combination of bortezomib (B) with rituximab (R) and dose adjusted (DA), infusional EPOCH chemotherapy (etoposide, prednisone, vincristine, doxorubicin and cyclophosphamide) in patients with untreated MCL. Patients are treated with one cycle of B 1.5 mg/m2 i.v. on days 1, 4, 8, and 11; followed by 6 cycles of DA-EPOCH-R-B induction therapy. Patients who achieve at least PR are then randomized to receive B maintenance therapy for 18 months versus observation followed by B if progression occurs. We obtain lymph node biopsies before initiating treatment and on day 2, 12–24 hours after the first dose of bortezomib. In order to analyze the molecular effects of B on tumor cells and to identify predictors of response we plan extensive molecular studies including gene expression profiling and proteomic analysis. Here we report on the effect of single agent B in a 64 year old African American male with leukemic MCL. The patient had been well until a few months prior when he underwent unrelated surgery and was found to have mild anemia and lymphocytosis. When he presented to our institution he had a WBC of 25K/μl, absolute lymphocyte count 19K/μl, Hb 11.7g/dl and platelets 164K/μl. Blood smear revealed medium to large lymphocytes with a high n/c ratio and folded, indented nuclei with prominent nucleoli. Flow cytometry was consistent with MCL. Bone marrow examination showed up to 60% cellularity composed predominantly of an interstitial infiltrate of Cyclin D1 positive lymphocytes. Physical exam and CT scan showed minimal lymphadenopathy but a large spleen measuring 19 cm in cranio-caudal dimension. During his work-up, the lymphocyte count increased further and he became progressively anemic. After informed consent, we initiated the first cycle with single agent B. Following doses #2 and #3, the patient reported grade III–IV fatigue and was briefly hospitalized. At the same time his lymphocyte count dropped from a high of 29K/μl to 15K/μl (day 5, 24 hours after dose #2), to 3,700/μl (day 9) to 2,200/μl (day 12). Flow cytometric analysis showed that B predominantly depleted the leukemic cells; the CD19+ cells dropped from a high of 26K/μl to less than 1,000/μl (day 12 and 14) while the number of T-cells remained in the normal range (Figure). The ANC was unaffected by B and the platelet nadir was 112K/μl. The impressive single agent activity and apparent tumor selectivity of bortezomib in MCL as exemplified by this patient’s response are encouraging. Analyses to characterize the molecular effects of B in the lymphoma cells are ongoing and may help identify the molecular basis for the potent anti-tumor effects of B in MCL. Figure Figure

Purpose Romidepsin is a structurally unique, potent class 1 selective histone deacetylase inhibitor. The primary objective of this international, pivotal, single-arm, phase II trial was to confirm the efficacy of romidepsin in patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). Patients and Methods Patients who were refractory to at least one prior systemic therapy or for whom at least one prior systemic therapy failed received romidepsin at 14 mg/m2 as a 4-hour intravenous infusion on days 1, 8, and 15 every 28 days. The primary end point was the rate of complete response/unconfirmed complete response (CR/CRu) as assessed by an independent review committee. Results Of the 131 patients enrolled, 130 had histologically confirmed PTCL by central review. The median number of prior systemic therapies was two (range, one to eight). The objective response rate was 25% (33 of 130), including 15% (19 of 130) with CR/CRu. Patient characteristics, prior stem-cell transplantation, number or type of prior therapies, or response to last prior therapy did not have an impact on response rate. The median duration of response was 17 months, with the longest response ongoing at 34+ months. Of the 19 patients who achieved CR/CRu, 17 (89%) had not experienced disease progression at a median follow-up of 13.4 months. The most common grade ≥ 3 adverse events were thrombocytopenia (24%), neutropenia (20%), and infections (all types, 19%). Conclusion Single-agent romidepsin induced complete and durable responses with manageable toxicity in patients with relapsed or refractory PTCL across all major PTCL subtypes, regardless of the number or type of prior therapies. Results led to US Food and Drug Administration approval of romidepsin in this indication.

PurposeDespite high initial remission rates, most lymphomas relapse and require further therapy. The mammalian target of rapamycin (mTOR) pathway is a validated target in mantle cell lymphoma, but has not been extensively evaluated in other lymphomas.Patients and MethodsWe performed a phase II trial of single-agent temsirolimus 25-mg weekly in patients with relapsed aggressive and indolent lymphomas. The primary objective was overall and complete response rate. Patients were stratified by histology: group A (diffuse large B-cell lymphoma, transformed follicular lymphoma), group B (follicular lymphoma), and group C (chronic lymphocytic leukemia/small lymphocytic lymphoma, and other indolent lymphomas).ResultsEighty-nine patients were treated, with outcome strongly dependent on histology. Group A had an overall and complete response rate of 28.1% and 12.5%, respectively, and median progression-free survival (PFS) of 2.6 months and median overall survival (OS) of 7.2 months. Group B had overall and complete response rates of 53.8% and 25.6%, respectively, and median PFS of 12.7 months; median OS has not yet been reached. Group C had a partial response rate of 11% with no complete responders. Toxicity was mainly mild and/or reversible myelosuppression and mucositis; however, four patients developed pneumonitis.ConclusionsSingle-agent temsirolimus has significant activity in both diffuse large B-cell lymphoma and follicular lymphoma, although the durability of responses and PFS are longer for patients with follicular lymphoma. This is the first report of substantial activity of temsirolimus in lymphomas other than mantle cell lymphoma, and supports further evaluation of mTOR as a target in these diseases.
