7532 Background: Mantle Cell Lymphoma (MCL) is characterized by t(11;14) resulting in over expression of cyclin D1, a member of the phosphatidylinosital 3-kinase (PI3K) pathway. Temsirolimus is a novel inhibitor of the mammalian target of rapamycin (mTOR) kinase. Previous studies with weekly temsirolimus at a dose of 250mg demonstrated a 38% overall response rate in 35 patients (JCO 23 (23); 5347–56, 2005). Thrombocytopenia was frequently observed and was dose limiting. The current study tested whether low-doses (25mg) of temsirolimus could produce a similar overall response rate (ORR) with less toxicity. Methods: Eligible patients had biopsy proven cyclin D1 positive MCL and had relapsed or were refractory to therapy. Patients received temsirolimus 25mg IV weekly as a single agent. Patients were restaged after 1 cycle (4 doses), after 3 cycles, and every 3 cycles thereafter. Patients with a tumor response after 6 cycles were eligible to continue drug for a total of 12 or 2 cycles after complete remission (CR) and then were observed without maintenance. The goal was to achieve an ORR of at least 20%. Results: Twenty-nine patients were enrolled between March and August 2005. Twenty-two patients have completed therapy. One patient with a major protocol violation on cycle-1 and one ineligible patient were excluded, leaving 27 evaluable patients. The ORR was 41% (11/27), with 1 CR and 10 PRs. Early evaluation of TTP showed a median of 5.5 months (95% CI: 3.3–7.7) and the duration of response for the 11 responders was 6.2 months (95% CI: 3.6 to not yet reached). These results compare favorably with the 6.5 months and 6.9 months, respectively, found in previous trials that used 250 mg. The median dose delivered per month was 80 mg (range, 10–100 mg). Sixteen (59%) of patients required a dose reduction. The median time on treatment was 4.4 months (95% CI, 3.3–7.7). The incidence of grade 3 and 4 thrombocytopenia was 12% and 0%, respectively. One patient experienced grade 5 infection without neutropenia, which was considered unrelated to CCI-779. Conclusions: Single agent CCI-779 at a dose of 25mg has anti-tumor activity in relapsed MCL similar to the 250 mg dose. This study indicates that combinations of temsirolimus with other agents should be feasible. [Table: see text]

Abstract Purpose: Mantle cell lymphoma (MCL) is characterized by a t(11;14) resulting in overexpression of cyclin D1, a member of the phosphatidylinosital 3 kinase (PI3K) pathway. This study tested whether CCI-779, which inhibits the PI3K pathway at the level of the mammalian target of rapamycin (mTOR) could produce tumor responses in patients (pts) with MCL. Patients and Methods: Eligible pts had biopsy-proven, cyclin D1 positive MCL and had relapsed or were refractory to therapy. Pts received CCI-779 250 mg IV every week as a single agent. Pts were re-staged after 1 cycle (4 doses) and every 3 cycles thereafter. Pts with a tumor response after 6 cycles were eligible to continue drug for a total of 12 cycles or 2 cycles after complete remission (CR) and then were observed. Results: Thirty-five pts were enrolled and evaluable for toxicity; 1 patient had MCL by histology but was cyclin D1 negative and ineligible for efficacy evaluation. The median age was 70 years (range, 38–89), 91% were stage 4, and 69% had ≥ 2 extranodal sites. Pts had received a median of 3 prior therapies (range, 1–11) and 54% were refractory to their last treatment. The overall response rate was 38% (13/34) with 1 CR (3%) and 12 PRs (35%), surpassing the pre-defined criteria for a promising agent. Responses tended to occur rapidly with median time to response of 1 month (range, 1–8). To date, 26 patients have progressed, with a median time-to-progression of 6.8 months (95% CI: 3.8 – 9.7). Median duration of response for the 13 responders was 5.7 months (95% CI: 5.2 – 13.2). Overall, 32 out of 35 patients who received treatment had grade 3 or 4 toxicity. The most common toxicities were hematologic with grade 3 (n=24) or grade 4 (n=4). Thrombocytopenia was the most frequent grade 3/4 toxicity (n=25) and the largest cause of dose-reductions, although counts typically recovered within one week. Only 4 patients could tolerate sustained 250 mg per week throughout their treatment (including one who went on to alternate treatment after 1 cycle) and the median dose/month was 175 mg. Conclusions: Single-agent CCI-779 has substantial anti-tumor activity in relapsed MCL. This study demonstrates that agents, which selectively target cellular pathways dysregulated in MCL cells can produce therapeutic benefit. The high response rate warrants further studies of this agent in MCL, but the high incidence of hematologic toxicity suggests that a lower dose should be explored. CCI-779 at 25mg is currently being evaluated in MCL through an NCCTG trial

18542 Background: Indolent non-Hodgkin’s lymphoma (I-NHL) account for 20% of all of NHL in Japan, and they are increasing in number. More than 80% of the patients who achieve a complete remission with the initial treatment, will require salvage therapy. Recently, cladribine (2-CdA), a purine analogue is receiving much attention, because, even as a single agent, it has shown a high efficacy for I-NHL. The aim of our study was to determine the effectiveness and toxicity of combined chemotherapy consisting of 2-CdA, cyclophosphamide (CYP), mitoxantrone (MIT), rituximab (R-CCM) in the treatment of refractory or relapsed I-NHL. Methods: Patient eligibility criteria were: Previously treated patients with I-NHL, refractory or relapsed disease, no chemotherapy or irradiation within 4 weeks prior to the study, life expectancy of at least 3 months, age: 20–75, perfomance status of 0–3, adequate function ( bone marrow, liver, kidney, lung, heart) and written informed consent. The treatment regimen was: 2-CdA given at a dose of 0.09 mg/kg/day in a 2-h intravenous infusion from day 2–4, CYP 200 mg/m2/day from day 2–4, MIT 8 mg/m2/day on day 2 and rituximab 375 mg/m2/day on day .Primary end point was overall response rate. Results: 9 patients were enrolled, 7 (2 with mantle cell lymphoma, MCL; and 5 with follicular lymphoma, FL) were eligible. Mean Age was 63(51–72). The mean observation time was 121 days(47–314). Overall response rate (complete and partial) just after this therapy was 85.7%, one was progressive disease. One of PR one relapsed and died ten months after this regimen. The major toxicity was myelosuppression. Grade-III and -IV neutropenia was seen in 7 patients, grade-III thrombocytopenia in one and grade-III hemorrhagic cystitis in one, but all of them recovered from these toxicity. After the treatment, Grade-IV pneumonia and grade-III left-ventricular diastolic dysfunction was seen in the PD patient and passed away. Conclusions: the R-CCM is effective and safe in a combined regimen for relapsed and refractory I-NHL patients. We have just begun this new regimen, therefore, further investigations with larger population are warranted. No significant financial relationships to disclose.

Abstract Background There is no standard treatment for R/R MCL that fail first line treatment. Non cross resistant regimens are usually used, which provided sometimes good overall response rate (until 93%) but with a minor disease control (PFS<2years). [1] The main objective of these salvage regimens is to bypass disease resistance, to obtain more profound ( deep or durable) response and to ensure, in younger patients, the option of performing autologous or allogenic stem cell transplantation. For older patients prolonging disease free survival is the aim. The new combination RiVBD (Rituximab-Bendamustine-Bortezomib-Dexametasone) has recently shown to be an effective regimen in frontline for eldery patients with a good tolerability profile (NCT 01457144). [2] Many French centers have also used this association for the R/R patients. Aim To explore the efficacy of the RiBVD regimen in the salvage therapy setting following failure of one, two or more prior treatments. Methods We proposed to all French LYSA partner centers a survey to retrospectively evaluate the efficacy of the RiBVD regimen in R/R MCL patients, regardless of prior treatments used. The RiBVD regimen comprises : Rituximab 375mg/sqm D1, Bendamustine 90mg/sqm D1 and D2, bortezomib 1,3mg/sqm D1, D4, D8, D11 and dexamethasone 40 mg D2. Analysis was performed in June 2016. Results From January 2012 to December 2015, 49 patients from 17 French hematological centers were recruited to the study. The median age was 72 years (50-91y) with 14 young (<65y) and 35 older patients (> 65y). Thirty eight cases presented with classic MCL variant and 11 had a blastoid variant. All patients but one were CD20+, CD5+, CD10- and were positive CYCLIN D1 expression and/or the t(11;14)(q13;q32). Eighteen patients presented a t(11;14) (q13;q32).The CYCLIN D1 negative patient had a t(11;14). Treatment history: Twenty seven patients received RiBVD in second line, 12 in third line and 10 patients after the third lines. Twenty two patients were refractory to their previous line and 27 were in relapse. Before RiBVD 44/49 patients (90%) had received high dose cytarabine, 3 Ibrutinib and 14 patients were intensified (11 at diagnosis, 3 in relapse). Efficacy: The global overall response rate (ORR) was 75% (37/49, 23 CR and 14 PR). For patients treated in 2nd line, the ORR was 85% (23/27, 16 CR and 7 PR), in 3nd line 58% (7/12, 4 CR and 3 PR), and 70% (7/10) for the others (3 CR and 4 PR). Young patients had an ORR of 64% (9/14, 8 CR, 2 RP) and elderly pts 77% (27/35, 15 CR, 12 PR). For relapsed and refractory pts the ORR was respectively 85% (23/27, 15 CR and 8 PR) and 63% (14/22 with 8 CR and 6 PR). For Classic and blastoid variants the ORR was 81.5% (31/38, 20 CR and 11 PR) and 54% (6/11, 3 CR and 3 PR) respectively. Note that 2/3 pts receiving RiBVD regimen post Ibrutinib failure, reached PR (n=2) and showed stable disease (n=1). Major toxicities were seen in 31 pts (63%) with grade 3/4 hematological toxicity in 22 pts, grade 3 neurotoxicity in 3 pts, grade 3/4 cardiotoxicity in 3 pts, grade 3/4 infectious complications in 8 pts, grade 4 fatigue in 3 pts and grade 3 digestive-tract or cutaneous toxicity in one pt each. At the update point, 17 pts had died, 15 for lymphoma progression, 2 for TRM while experiencing a CR (infectious and leukemia). The follow-up of the 32 surviving pts was 14.5 month. The median PFS was 9 months for the 49 pts. The PFS was statistically affected by the pathologic type (classic vs Blastoid, p=0.03), the number of prior treatment (one vs >one, p=0.04) and response to RiBVD (CR vs PR vs no response, p<0.0001 with a median PFS not reached for CR pts, 6 months for PR and 2 months for no response. The age (<65 vs >65) or the state (relapse or refractory) at the time of RiBVD had no impact on PFS. Conclusion The RiBVD regimen which shows remarkable efficacy in frontline treatment of elderly MCL pts, shows potential as a salvage therapy for refractory or relapsed MCL following cytarabine based treatment. This is particularly true for the 47% of patients achieving CR for which 2 years PFS was 71% regardless of their age. 1. Cheah CY, Seymour JF, Wang ML. Mantle Cell Lymphoma.

Abstract Background: Bortezomib (B) belongs to a new class of anti-cancer agents, the proteasome inhibitors, and has documented activity in multiple myeloma and mantle cell lymphoma (MCL). Preclinical studies suggest that B has synergistic activity with rituximab (R), which provides a rationale for the exploration of treatment combinations. We therefore evaluated the activity and safety of B in combination with R and dexamethasone (BORID) in patients with relapsed and refractory MCL (phase II trial). Methods: A treatment cycle consists of B at 1.3 mg/m2 administered on days 1, 4, 8, and 11, R at 375 mg/m2 administered on day 1, and dexamethasone 40 mg orally on days 1 to 4. Cycles are repeated every 3 weeks for a total of 6 treatment cycles. Patients (pts) achieving a response received 4 additional doses of R as maintenance (every 8 weeks). Pts with progressive MCL after at least one prior line of therapy (including CHOP or a CHOP-like regimen) were eligible. Results: We have completed enrollment of 16 pts (median age, 67 years; range, 48 to 75 years) after a median of 3 lines of prior therapies (range, 1 to 6, prior rituximab in 88%; thalidomide in 50%; high-dose therapy in 31%; a fludarabine-containing regimen in 31%). Median time between start of frontline therapy and study inclusion was 42 months (range, 11 to 98 months). Severe adverse events (&gt; grade II) included infections (herpes zoster in 2 pts, bacterial pneumonia, mucosal candidiasis), peripheral neuropathy (3 pts), fatigue (2 pts) and vasculitic skin infiltrates in 3 pts. Thrombopenia (&lt; 50 G/L) occured in 2 pts. All adverse events were managable by standard means of supportive care and prolongation of the treatment interval between cycles. Overall response rate was 69% (11 of 16 pts), with 6 pts achieving a CR (38%; confirmed by PET-scan in 5 pts) and 5 pts reaching a PR. Skin infiltrates (histologically proven T-cell infiltrates) preceded achievement of CR in 2 pts. Remission status appeared to be associated with progression-free survival (PFS): Patients in CR had longer PFS (29+, 24+, 21+, 12+, 12, and 10+ months) compared to patients in PR (median 8.5 months, range 6 – 15). Conclusions: BORID has promising activitiy (69% overall response rate; CR rate 38%) and managable toxicity in this patient population with predominantly heavily pretreated MCL. Achievement of a CR emerged as an important factor for sustained disease control. Further evaluation of this regimen, in particular in pts at an earlier phase of the disease, is warranted.

Abstract Abstract 2803 Introduction: Mantle cell lymphoma (MCL) accounts for 6% of all B-cell lymphomas and remains incurable for most patients. Those who relapse after first line therapy or hematopoietic stem cell transplantation have a dismal prognosis with short response duration after salvage therapy. On a molecular level, MCL is characterised by the translocation t[11;14] leading to Cyclin D1 overexpression. Cyclin D1 is downstream of the mammalian target of rapamycin (mTOR) kinase and can be effectively blocked by mTOR inhibitors such as temsirolimus. We set out to define the single agent activity of the orally available mTOR inhibitor everolimus (RAD001) in a prospective, multi-centre trial in patients with relapsed or refractory MCL (NCT00516412). The study was performed in collaboration with the EU-MCL network. Methods: Eligible patients with histologically/cytologically confirmed relapsed (not more than 3 prior lines of systemic treatment) or refractory MCL received everolimus 10 mg orally daily on day 1 – 28 of each cycle (4 weeks) for 6 cycles or until disease progression. The primary endpoint was the best objective response with adverse reactions, time to progression (TTP), time to treatment failure, response duration and molecular response as secondary endpoints. A response rate of ≤ 10% was considered uninteresting and, conversely, promising if ≥ 30%. The required sample size was 35 pts using the Simon's optimal two-stage design with 90% power and 5% significance. Results: A total of 36 patients with 35 evaluable patients from 19 centers were enrolled between August 2007 and January 2010. The median age was 69.4 years (range 40.1 to 84.9 years), with 22 males and 13 females. Thirty patients presented with relapsed and 5 with refractory MCL with a median of two prior therapies. Treatment was generally well tolerated with anemia (11%), thrombocytopenia (11%), neutropenia (8%), diarrhea (3%) and fatigue (3%) being the most frequent complications of CTC grade III or higher. Eighteen patients received 6 or more cycles of everolimus treatment. The objective response rate was 20% (95% CI: 8–37%) with 2 CR, 5 PR, 17 SD, and 11 PD. At a median follow-up of 6 months, TTP was 5.45 months (95% CI: 2.8–8.2 months) for the entire population and 10.6 months for the 18 patients receiving 6 or more cycles of treatment. Conclusion: This study demonstrates that single agent everolimus 10 mg once daily orally is well tolerated. The null hypothesis of inactivity could be rejected indicating a moderate anti-lymphoma activity in relapsed/refractory MCL. Further studies of either everolimus in combination with chemotherapy or as single agent for maintenance treatment are warranted in MCL. Disclosures: Off Label Use: everolimus for the treatment of mantle cell lymphoma.

Abstract Abstract 1665 Poster Board I-691 Mantle cell lymphoma (MCL) is an aggressive, incurable B-cell malignancy that represents approximately 6% of lymphoma cases. Patients with MCL who relapse after conventional therapy or stem cell transplantation have a poor prognosis and are candidates for treatment with novel agents. The characteristic feature of MCL is overexpression of cyclin D1. Cyclin D1 is under the control of the phosphatidylinositol-3 kinase signal-transduction pathway and is downstream of the mammalian target of rapamycin kinase (mTOR). We have previously shown that temsirolimus (CCI-779), a dihydroester of the selective mTOR inhibitor rapamycin, is an active antitumor agent in MCL. In previous phase 2 trials of temsirolimus as a single agent, we observed a 40% overall response rate (ORR) with a median duration of response (DR) of 6 months in patients with relapsed or refractory disease (J Clin Oncol 23:5347-56, 2005; Cancer 113:508-514, 2008). Due to the fact that rituximab has improved the response rate and overall outcome of lymphoma patients when combined with chemotherapy, we tested the efficacy and toxicity of temsirolimus in combination with rituximab in patients with MCL. Eligible patients with confirmed relapsed or refractory MCL based on morphologic and phenotypic features received temsirolimus 25 mg intravenously every week and four weekly doses of rituximab with the first cycle and then one dose of rituximab every other cycle. Patients with a tumor response after six cycles were eligible to continue treatment for a total of 12 cycles or two cycles after complete remission, and were then observed without maintenance. Seventy-one patients were enrolled between May 2005 and March 2009. The median age was 67 years (range, 44 to 86 years), with 51 males and 20 females enrolled. Patients had received a median of two prior therapies (range, 1-9), 31% had received a prior stem cell transplant and 28% were rituximab refractory. The ORR was 48% (34/71 patients) with 20% (14/71) complete responses and 28% (20/71) partial responses. The median DR was 9.5 months (95% CI, 4.5 to 11.3 months). The median DR in the rituximab sensitive patients was 9.5 months (CI: 4.5-11.6) and 7.15 months (CI: 4.1-11.3) in the rituximab refractory patients (p= 0.73). While the combination was generally well tolerated, 12 patients experienced grade 4 toxicity and 2 patients died while on therapy – both from progressive disease. Hematologic toxicities were the most common, with 5 patients having grade 4 thrombocytopenia and 3 having grade 4 neutropenia. This study demonstrates that temsirolimus in combination with rituximab is well tolerated and has substantial antitumor activity in relapsed MCL. Further comparative studies of this combination in MCL are therefore warranted. Disclosures Witzig: Wyeth: Patents & Royalties.

PURPOSE Most patients with mantle cell lymphoma (MCL) are older. In this study, we investigated the efficacy and safety of a chemotherapy-free combination with ibrutinib and rituximab (IR) in previously untreated older patients with MCL (age ≥ 65 years). METHODS We enrolled 50 patients with MCL in this single-institution, single-arm, phase II clinical trial ( NCT01880567 ). Patients with Ki-67% ≥ 50% and blastoid morphology were excluded. Ibrutinib was administered with rituximab up to 2 years with continuation of ibrutinib alone. The primary objective was to assess the overall response rate and safety of IR. In evaluable samples, whole-exome sequencing and bulk RNA sequencing from baseline tissue samples were performed. RESULTS The median age was 71 years (interquartile range 69-76 years). Sixteen percent of patients had high-risk simplified MCL international prognostic index. The Ki-67% was low (< 30%) in 38 (76%) and moderately high (≥ 30%-50%) in 12 (24%) patients. The best overall response rate was 96% (71% complete response). After a median follow-up of 45 months (interquartile range 24-56 months), 28 (56%) patients came off study for various reasons (including four progression, 21 toxicities, and three miscellaneous reasons). The median progression-free survival and overall survival were not reached, and 3-year survival was 87% and 94%, respectively. None of the patients died on study therapy. Notably, 11 (22%) patients had grade 3 atrial fibrillation. Grade 3-4 myelosuppression was seen in < 5% of patients. Differential overexpression of CCND1, BIRC3, BANK1, SETBP1, AXIN2, and IL2RA was noted in partial responders compared with patients with complete response. CONCLUSION IR combination is effective in older patients with MCL. Baseline evaluation for cardiovascular risks is highly recommended. Randomized trial is needed for definitive conclusions.

Abstract Abstract 3698 Background: Follicular, marginal zone and mantle cell lymphomas are indolent lymphomas that tend to recur with decreasing intervals of remissions. Vorinostat (SAHA) is an orally administered hydroxamic acid histone deacetylase inhibitor with activity against class I and II deacetylases. Single agent vorinostat has an overall response rate of 29% in all indolent lymphomas (47% in follicular lymphoma) with prolonged disease free survival. (Kirschbaum, JCO 2009) Preclinical data suggests enhanced activity for the combination of vorinostat plus rituximab. We report the clinical results of a phase II study of the combination of vorinostat plus rituximab. Methods: These are the updated results of our two-stage phase II study in patients with newly diagnosed, relapsed or refractory follicular, marginal zone, or mantle cell lymphoma. Vorinostat is given at 200 mg PO twice daily for 14 consecutive days on a 21 day cycle. Rituximab is given on day 1 of each cycle. CT scanning and/or FDG-PET are performed after every three cycles. Patients may have received up to four prior chemotherapy regimens including tositumomab or ibritumomab; previous autologous transplant is allowed. The primary endpoint was the overall response rate according to Revised Response Criteria for Malignant Lymphoma (Cheson 2007). Results: 26 eligible patients were accrued thus far. See Table 1 for baseline characteristics. Outcomes are available on 23 patients: the overall response (CR+PR) rate thus far is 35% (8/23) The CR rate for all patients is 30% (7/23). The response rate for untreated patients (5 FL, 1 MZL) is 66.6% (4/6, all CR). The other two patients remain on study with prolonged stable disease. The formal response rate thus far for relapsed/refractory patients is 23.5% (4/17). By histology, the response rate is 35% (7/19) for FL, 0/2 for mantle cell, 1/1 for MZL, and 0/1 for lymphoplasmacytic lymphoma. The median time to achieve CR is 12 months. Of the 7 patients who achieved CR, 3 have relapsed while off treatment and were retreated with vorinostat plus rituximab. 1 achieved CR and is 13 months into treatment, 1 achieved PR and is 23 months into treatment, while 1 transformed both to Hodgkin lymphoma and diffuse large B cell lymphoma (biopsy proven). The median time to treatment failure for patients achieving CR is 38 months, with 6 ongoing, including the two retreated patients (14, 27, 29, 29, 31, and 35 months). Of non-responders, 8 patients achieved stable disease for at least 9 cycles with one SD for 63+ cycles. The disease control rate for > 9 cycles (CR+PR+SD) is 69.6% (16/23). Five patients were taken off study for reasons other than progression (2 patients choice, 1 to transplant, 1 for concomitant medication violation, and 1 physician choice). The median time to treatment failure for all patients was 9 months (95% CI, 6 months, NR). Treatment was well tolerated. Grade 4 toxicities possibly attributable to study drug include neutropenia (n=1), asymptomatic thrombosis (n=4), and thrombocytopenia (n=2). Grade 3 possibly related toxicities include fatigue (n=7), hyperglycemia (n=3), dehydration (n=2), and one each of thrombocytopenia, neutropenia, anemia, hypophosphatemia, hypotension, pneumonia, diarrhea, diverticulitis, and syncope. The thromboses were nonclinical pulmonary embolism discovered incidentally on CT scan, and resulted in amending the study to include 40 mg enoxaparin as prophylaxis, resulting in no further thromboses identified. Conclusions: The combination of vorinostat with rituximab is well tolerated, and shows encouraging activity against newly diagnosed, as well as relapsed/refractory indolent lymphoma. Durable responses can be achieved. Extended treatment with this combination is feasible and well tolerated, and retreatment with this regimen is efficacious in previous responders who relapsed. Disclosures: Off Label Use: Use of vorinostat in combination with rituxan for indolent B cell lymphomas.

8027 Background: The histone deacetylase inhibitors (HDIs) are a class of differentiating agents undergoing clinical testing. Like other HDIs, romidepsin (FK228) modulates expression of genes involved in cell cycle regulation and markers of differentiation in cancer cell lines, leading to induction of differentiation or apoptosis. Romidepsin has demonstrated clinical activity in patients with T-cell lymphoma. Methods: Patients with CTCL (42) or PTCL (36) were enrolled in the NCI multi-institutional trial and assigned to cohorts based on extent of prior therapy and pathology. Romidepsin is administered on days 1, 8, and 15 of a 28 d cycle with a starting dose of 14mg/m2. Responses for patients with PTCL are measured using Cheson criteria, and CTCL using RECIST criteria. Results: Cohort one, composed of 27 patients who had previously received no more than 2 prior cytotoxic regimens of chemotherapy, has completed enrollment. Responses observed include 3 patients with CR and 7 patients with partial responses, yielding an overall response rate of 37%. Of note, responses were observed independent of stage of disease. Among 18 patients with stage IV disease, 6 patients had a complete or partial response, including 3 patients with Sézary syndrome. When including patients with greater than 2 prior cytotoxic regimens, the overall response rate was 31%. A replicate arm has been opened with the goal of confirming the response rate observed in the first cohort. Response data have not been evaluated from this arm at this time. Responses observed in 36 patients with refractory or relapsed PTCL includes 3 patients with CR and 8 patients with partial responses, comprising an overall response rate of 30%. Responses were observed independent of prior therapy, with some patients having undergone prior stem-cell transplant. Molecular endpoint analysis was performed on peripheral mononuclear cells (PBMNCs) and tumor biopsies from treated patients evaluating histone acetylation and changes in gene expression. Conclusions: Romidepsin as a single agent appears to have significant single agent activity in patients with CTCL and PTCL. Combination therapy with romidepsin may increase efficacy and should be pursued. This protocol remains open to accrual. No significant financial relationships to disclose.

PurposeTo evaluate the effect of single-agent rituximab given at the standard or a prolonged schedule in patients with newly diagnosed, or refractory or relapsed mantle cell lymphoma (MCL).Patients and MethodsAfter induction treatment with the standard schedule (375 mg/m2weekly × 4), patients who were responding or who had stable disease at week 12 from the start of treatment were randomly assigned to no further treatment (arm A) or prolonged rituximab administration (375 mg/m2) every 8 weeks for four times (arm B).ResultsThe trial enrolled 104 patients. After induction, clinical response was 27% with 2% complete responses. Among patients with detectable t(11;14)-positive cells in blood and bone marrow at baseline, four of 20, and one of 14, respectively, became polymerase chain-reaction–negative after induction. Anemia was the only adverse predictor of response in the multivariate analysis. After a median follow-up of 29 months, response rate and duration of response were not significantly different between the two schedules in 61 randomly assigned patients. Median event-free survival (EFS) was 6 months in arm A versus 12 months in arm B; the difference was not significant (P = .1). Prolonged treatment seemed to improve EFS in the subgroup of pretreated patients (5 months in arm A v 11 months in arm B; P = .04). Thirteen percent of patients in arm A and 9% in arm B presented with grade 3 to 4 hematologic toxicity.ConclusionSingle-agent rituximab is active in MCL, but the addition of four single doses at 8-week intervals does not seem to significantly improve response rate, duration of response, or EFS after treatment with the standard schedule.
