Lenalidomide plus rituximab in patients with rituximab-resistant indolent B-cell and mantle cell lymphomas: 10-year follow-up.

7539 Background: Lenalidomide (len) plus rituximab is now a standard-of-care option for indolent B-cell non-Hodgkin lymphomas (iNHL) and mantle cell lymphomas (MCL). We previously demonstrated the efficacy of len plus rituximab in patients (pts) with rituximab-refractory iNHL and MCL (Chong et al. Clin Can Res 2015). We now report the longest experience to date with this regimen. Methods: We conducted an open-label phase II trial in pts with iNHL or MCL and rituximab resistance, defined as failure to respond or progression of disease within 6 months (mo) of rituximab or a rituximab-containing regimen. Pts received len 10 mg daily for 8 weeks, followed by 4 weekly doses of rituximab 375 mg/m2 and continued len maintenance until disease progression, toxicity or pt choice. Results: 50 pts (30 FL, 14 MCL, 2 MZL, 4 SLL) were treated between 2008-2012. Median follow-up was 10.5 years (yr). Pts received a median of 3 prior therapies (range: 1–7). Progression free survival (PFS) for all pts at 5 and 10 yrs was 20.0% [95%CI 8-35] & 13% [95%CI 3-30%]; 5- and 10-yr response duration (RD) was 27% [95% CI 12-46] and 18% [95% CI 4-40], respectively; 5- and 10-yr overall survival (OS) was 58% [95%CI 43-70] and 45% [95%CI 30-58], respectively. 5-yr OS from the time pts were deemed rituximab-resistant is 64.0% and 10-yr OS 51.9%. For pts with FL, 5- and 10-yr PFS were both 13%, and 5- and 10-yr OS were 60% and 40%. For MCL, 5- and 10-yr PFS were both 25% and 5- and 10-yr OS were 50% and 36%. At 10.5 yr, 4 pts (2 FL, 1 MCL, 1 MZL) remain in complete remission (CR), 3 of whom discontinued len at 7.0-yr, 8.8-yr and 10.1-yr in CR. 1 pt with FL discontinued study in CR after 11.6-yr but continues on commercial len at 5 mg daily. The most common grade 1–2 adverse events (AEs) requiring dose reductions were neuropathy (n = 3) and diarrhea (n = 5), which all resolved with dose reduction. The most common grade 3–4 AEs requiring dose reductions were neutropenia (n = 6, 12%) and tumor flare (n = 3, 6%). Pts discontinued therapy due to toxicity at a median of 4.9 mo (range 0.3–25.7) from len start due to grade 3–4 rash (n = 2), grade 2 abdominal pain (n = 1), and grade 3–4 thrombocytopenia (n = 2). Only 1 patient discontinued len after > 1 yr (25.7 mo) due to persistent diarrhea. The pt who developed grade 2 abdominal pain was retreated with len without recurrence of pain and sustained a second CR for 5 yrs. 5 (10%) pts developed secondary cancers at a median of 15.5 mo (range: 0.8–50.5) from starting len, including 2 hematological (acute myeloid leukemia, B-acute lymphoblastic leukemia) and 3 solid cancers (NSCLC, renal cell carcinoma, prostate cancer). Prior to enrollment, 4/5 of the patients with secondary cancers had received alkylating agents and 3/5 had received anthracyclines. Conclusions: These data represent the longest reported outcomes for len plus rituximab in NHLs. We demonstrate durable responses and a manageable safety profile with rituximab plus low-dose len.

6511 Background: BOS is an oral dual Src/Abl kinase inhibitor with potent activity in Ph+ leukemia. Methods: Efficacy and safety of BOS 500 mg/d was evaluated in older (≥65 y; n = 119) and younger (<65 y; n = 451) pts in 3 cohorts: chronic phase chronic myeloid leukemia (CP CML) after imatinib (IM; CP2L cohort; n = 287); CP CML after IM + dasatinib (DAS) and/or nilotinib (NIL; CP3L cohort; n = 119); and accelerated/blast phase (AP/BP) CML or acute lymphoblastic leukemia after IM ± DAS and/or NIL (ADV cohort; n = 164). Results: Baseline events (≥65 y vs <65 y) included respiratory disorders (35% vs 13%), cardiac disorders (29% vs 9%), and diabetes (4% vs 4%). Median baseline medications were 3 (≥65 y) and 5 (<65 y). Median BOS duration was 11 mo and median follow-up was 31 mo for all pts. 80% of ³65 y and 67% of <65 y pts discontinued BOS, including 32% and 18% due to an adverse event (AE; most commonly thrombocytopenia [6% vs 3%]). Rates of response were similar or lower in older versus younger pts (Table). On-treatment transformation to AP/BP CML was similar between groups. Incidences of nonhematologic treatment-emergent AEs were generally similar between older and younger pts, notably (all grades/grade ≥3 for ≥65 y vs <65 y): diarrhea (85%/9% vs 81%/8%), infection (56%/15% vs 49%/10%), and edema (8%/0% vs 4%/<1%). Common grade ≥3 lab abnormalities (≥65 y vs <65 y) were thrombocytopenia (35% vs 35%), neutropenia (21% vs 25%), and anemia (19% vs 19%). Conclusions: BOS demonstrated similar efficacy and acceptable safety in both older and younger pts across Ph+ leukemia cohorts. [Table: see text]

Abstract Abstract 1700 Poster Board I-726 Introduction Lenalidomide is an immunomodulatory drug with effects on the innate immune system that may enhance antibody-dependent cell mediated cytotoxicity as well as the development of specific anti-tumor immune responses. These immunologic effects may synergize with the action of rituximab. To test the efficacy of lenalidomide combined with rituximab, we are conducting a single center, open label phase II clinical trial in patients (pts) with indolent B-cell or mantle cell lymphomas previously resistant to rituximab. Patients and Methods Eligible pts must have relapsed/refractory indolent B-cell or mantle cell lymphoma with measurable disease that has failed to respond to or has progressed within six months of a standard course of rituximab monotherapy (375 mg/m2 weekly for at least four weeks) or a prior rituximab-containing chemotherapy regimen. Thus, all pts enrolled are considered rituximab-resistant. In Part I (lenalidomide + dexamethasone), pts receive two 28-day treatment cycles of lenalidomide 10 mg every day and dexamethasone 8 mg once weekly. After assessment of response to Part I, all pts receive a single course of rituximab 375 mg/m2, consisting of four weekly doses during cycle 3 (Part II: lenalidomide + dexamethasone + rituximab). Treatment with lenalidomide + dexamethasone continue during and subsequent to rituximab; stable and responding pts continue on lenalidomide + dexamethasone until disease progression or development of clinically unacceptable toxicity. Response assessment after Part II is performed three months after the first dose of rituximab. Results To date, 22 pts have started therapy; diagnoses included: follicular (n = 17), mantle cell (n = 2), small lymphocytic (n = 2), and marginal zone (n = 1) lymphomas; median age was 59 years (range: 35 - 72); male: female ratio was 5:6; median number of prior therapies was 3 (range: 1 - 7); LDH was increased in 23%. For 21 pts with at least one follow-up visit, there were 2 deaths and 2 episodes of disease progression. One death due to myocarditis occurred during Part I treatment; one death due to lymphoma occurred in a patient removed from study due to grade 3 rash, which subsequently resolved. Both episodes of disease progression occurred in pts with follicular lymphoma, one of whom had been removed from study during Part 1 because of thrombocytopenia attributed to myelodysplasia. For all patients, at a median follow-up of 5.0 months (range: 0.3 - 12.3), progression-free survival (PFS) is 81% (95% CI: 51-94). For 10 pts with response assessments after Parts I and II, overall response rate (ORR) after Part I was 30% (3 CR; 6 SD; 1 PD) and ORR after Part II was 70% (5 CR; 2 PR; 2 SD; 1 PD). At a median follow-up of 7.8 months (range: 5.0 - 11.9), PFS is 89% (95% CI: 43-98) for these 10 pts. For pts who completed Parts I and II, grade 3 or 4 non-hematologic toxicities included hypokalemia (2/10 pts), hypophosphatemia (1/10 pts), and hypocalcemia (1/10 pts); grade 1 tumor flare occurred in one pt with follicular lymphoma. Conclusions Based on these preliminary data in rituximab-resistant patients with indolent B-cell or mantle cell lymphomas, the combination of continuous daily lenalidomide, low-dose weekly dexamethasone, and a single four week course of rituximab during cycle 3, achieves a high overall response rate with relatively durable responses. Additional follow-up and correlative studies will be presented. Disclosures Off Label Use: Lenalidomide is used in this trial for treatment of lymphoma..

Objectives: Tisagenlecleucel (CTL019) is a chimeric antigen receptor T cell- therapy that reprograms autologous T cells to target CD19+ leukemia cells, approved in the US (2017) and in the EU (2018). This study reports the feasibility, safety and efficacy of CTL019 in patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) treated in Robert-Debré and Saint-Louis University Hospitals (Assistance Publique-Hôpitaux de Paris/Université de Paris). Methods: Patients (pts) with an apheresis performed between march 1, 2016 and june 15, 2019, included in sponsored-clinical trials or treated within the French compassionate program or with the commercial product, were analyzed. All infused pts received a fludarabine-cyclophosphamide based lymphodepletion before a single infusion of CAR-T cells (2 to 5 x 106 CTL019/kg if less than 50 kg; a fixed dose of 1 to 2.5 x 108 CTL019/kg if > 50 kg) Results: 55 pts were referred from 25 French centers. Forty-one pts with a median number of relapses of 2 (range, 1-5) were infused with CTL019 at a median age of 18.2 y (range, 1-29.2). Eight pts were not infused due to progressive disease (n=4), screen failure (n=3) or fatal septic shock (n=1). Six pts were waiting to be infused at time of analysis. Out of the 41 infused pts, 26 had a prior history of allogeneic SCT (63%), 11 had received blinatumomab (27%). Among the 40 pts evaluable at one month post-infusion, 38 were in CR/CRi (95%) (one progression at day 5 after infusion and one toxic death at D6), 35/38 (92.1%) being clone-specific Ig-TCR MRD negative. After 3 months 21 out of 26 evaluable pts (81%) had a negative MRD. The 5 remaining MRD positive pts did relapse. No pt underwent allogeneic HSCT while in CR after CTL019 infusion. Median event free survival (EFS) and overall survival (OS) were not reached with a median follow up of 7.2 months (range, 0.2-36.3). The 18-month OS probability was 80% (95%CI, 58%-92%). The 18-month EFS probability was 58 % (95%CI, 37%-74%). Ten pts relapsed after a median time of 3.4 months (range, 1.9-10): 3 relapses were CD19+ and 5 CD19- (4 out of these 5 pts had a preexposure to blinatumomab), 2 being of undetermined status. Loss of B-cell aplasia (BCA) occurred in 9 pts after a median time of 3 months (range, 2-12), followed by relapse for 2 pts (one concomitant with loss of BCA and one 7 months later). Three pts received a second infusion of CTL019 for loss of BCA with no further expansion of CAR-T cells. Prior treatment with blinatumomab was a significant predictive factor for relapse (HR=6.082, 95%CI, 1.2-30, p=0.0005) in a univariate analysis. There was a trend toward increased risk of relapse with increased disease burden (≥ 5%) before lymphodepletion regimen (HR=2.4, 95%CI, 0.7-8, p=0.14). Twenty-two pts experienced a CRS (≥ grade 3: n=13, all ≥ 10 y). ICU was required for 14 pts (34%). One 29 year-old pt died of an uncontrollable CRS at day 6. Ten pts received tocilizumab, 4 pts siltuximab and 9 pts corticosteroids. Age ≥ 10 y (p=0.04) and a high disease burden just before lymphodepletion (marrow blasts ≥ 5%) (p=0.01) were associated with a higher risk of CRS ≥ grade 3. Nine neurological events have been reported, being reversible except in 2 cases (one death in combination with grade 5 CRS-cf supra-, one HHV6-related encephalitis with neurological sequelae). Among the 9 pts who presented neurological events, 8 experienced CRS grade ≥ 3 (RR=17.2, 95%CI, 3.22-100.3, p=0.0001). By day 28, unresolved neutropenia grade ≥ 3 was reported for 13 pts. G-CSF treatment was required in 21 pts overall. Thrombocytopenia grade ≥3 was reported for 14 pts. Conclusion: CTL019 confirms its efficacy with a high response rate after infusion and very encouraging early outcomes in a cohort of pts heavily pretreated for refractory or multiply relapsed B-ALL. Persistent remissions with a potential for cure were observed without additional HSCT, relapses occurring within the first year after infusion of CTL019. Accurate assessment of a potentially deleterious effect of Blinatumomab preexposure notable on CD19 negative relapse will need more pts and a longer follow-up. Toxicity profile was tolerable and manageable thanks to collaboration between intensivists, neurologists and hematologists. The identification of severe CRS predictive risk factors (high disease burden just before lymphodepletion and age ≥ 10 y) points towards the reinforcement of toxicity monitoring and treatment anticipation in these cases.

Abstract On behalf of the GRAALL group, the Czech Republic ALL group, the Finland ALL group and the EWALL group. Introduction. Treatment of older patients (pts) with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) remains an unmet medical need. Inotuzumab ozogamicin (INO), an anti-CD22 antibody conjugated to calicheamicin, is approved for the treatment of relapsed/refractory BCP-ALL in adults, sinusoidal obstruction syndrome (SOS) being the major adverse event associated with INO. A previous first line study conducted by the MDACC in pts 60 years or older successfully used INO in combination with a lower intensity version of the hyper-CVAD (mini-hyper-CVD). Due to the occurrence of SOS, the total doses were fixed at 1.3 mg/m² for cycle 1 followed by 3 cycles at 1 mg/m² (Kantarjian H et al. Lancet Oncol, 2018). Here, we aimed to assess the activity and safety of fractionated INO at a reduced dosage in combination with low-intensity chemotherapy as frontline therapy for older pts with CD22+ Philadelphia chromosome-negative (Ph-neg) BCP-ALL. Methods. EWALL-INO is a single arm prospective phase 2 multicentric study conducted in European centers belonging to the EWALL group. Eligibility criteria were pts aged 55y or older, performance status ≤2, and newly diagnosed CD22+ (20% or more of positive blast cells) Ph-neg BCP-ALL without central nervous system involvement. After a prephase including 5 days (D) of dexamethasone (DEX) 10mg per D and a single intrathecal injection (IT), the induction regimen was begun and split in 2 parts. Induction part I (Induc1) consisted of one triple IT, vincristine (VCR) 2 mg (1 mg over 70y) D1 D8 D15 D22 and DEX 20 mg D1D2 D8D9 D15D16 D22D23 combined with 3 injections of INO (0.8 mg/m² D1, 0.5 mg/m² D8 and D15). Induction part II (Induc2) was offered to pts in CR or CRp (CR with platelets < 100 G/l) after Induc1 or as salvage therapy. Induc2 consisted of DEX 20mg D1D8, cyclophosphamide (CY) 300 mg/m² D1 to D3, one triple IT D2 and 2 injections of INO (0.5 mg/m² D1 and D8). Pts in CR/CRp were programmed to receive 6 blocks of consolidation (Ara-C 1.5g/m²/12h adapted to renal clearance D1D2 and DEX 10mg/12h D1D2, cycles 1 and 4; Methotrexate (MTX) 1.5 g/m² over 24h D1, VCR 1 or 2 mg D1, one triple IT D2 and 6-mercaptopurin (6-MP) D1 to D7, cycles 2 and 5; CY 500 mg/m² D1D2, VP16 75 mg/m² D1D2, one triple IT D2 and MTX 25 mg/m² D1, cycles 3 and 6) followed by a POMP maintenance (VCR, 6-MP, MTX, DEX) during 18 months. Allograft was allowed after at least 3 blocks of consolidation at the discretion of the investigators. The evaluable population was pts who received at least 1 dose of INO. Analyses were by modified intention to treat and performed JUN 28, 2021. All pts gave informed consent. The study is registered at ClinicalTrials.gov under the NCT number: NCT03249870. Results. Between DEC 29, 2017 and JUN 22, 2021, 115 pts (out of 130 planned pts) were enrolled including 6 pts with screen failure. The first 90 eligible pts (up to MAR 1, 2021) were considered for this analysis to obtain a minimum of 4 months follow-up. Median age was 69y (range 55-84) and median follow-up for alive pts was 1.18 years (range 0.3-3.5). At time of analysis, 90 and 88 pts had started induc1 and induc2, respectively. Treatment related mortality was 2.2% (2/90) and CR/CRp rate was 85.5% (77/90, 6 CRp) after induc1. Three cases relapsed between induc1 and induc2 and 5 pts were salvaged by induc2 allowing to a CR/CRp rate of 87.7% (79/90, 8 CRp) after induc2. One pts died from refractory disease during induc2. One, 2, 3 4 and 5 injections of INO were administered to 2 (2.2%), 2(2.2%), 11 (12.2%), 2 (2.2%) and 73 pts (81.1%) respectively. Only 6 pts were allografted. One-year OS was estimated to be 78.5% (95%CI 68-85.9) and median OS was not reached. One-year relapse free survival was 74.5% (95CI 63.5-82.6) (Figure 1). Grade 3-4 liver toxicity was observed in 8 pts (8.8%) during the study including 3 pts (3.3%) developing SOS, 2 related to INO during induc1 and one occurred after transplant. Twenty-nine pts died during the follow-up, 16 from relapses (overall incidence 18%) and 13 from adverse events (overall incidence 14.4%), including one COVID19 fatal infection during consolidation. Conclusion. Fractionated inotuzumab ozogamicin at reduced doses (0.8/0.5/0.5/0.5 mg/m²) combined with low-intensity chemotherapy is a very active and well tolerated frontline therapy for older patients with CD22+ Ph-neg BCP-ALL.

Introduction: In spite of improvements in treatment of mantle cell lymphoma (MCL), this is still considered an incurable lymphoma entity, and the majority of patients eventually relapse. Ibrutinib is a very active agent in MCL, but in vitro has been shown to partially antagonize the activity of rituximab, by suppression of NK cell activity and subsequent ADCC. Lenalidomide, on the other hand, improves rituximab-induced ADCC. In this multi-centre open-label phase II trial, we evaluated safety and efficacy of this triplet combination in patients with relapsed or refractory MCL. Methods: Patients with MCL, relapsing after or refractory to at least one rituximab-containing chemotherapy regimen, WHO PS 0-3, and measurable disease were eligible. The primary endpoint was maximal overall response rate (ORR) measured with CT and PET/CT. Minimal residual disease (MRD) monitoring by PCR was performed during follow-up, according to EuroMRD criteria. Ion Torrent sequencing of the most frequently mutated genes in MCL was performed on frozen tumor cells from bone marrow at time of relapse. Health-related quality of life was assessed by the EORTC-QLQ C30 questionnaire before and during treatment. Treatment schedule: Induction phase: Up to twelve 28-day cycles with: Lenalidomide 15 mg p o daily, days 1-21, Ibrutinib 560 mg p o days 1-28, Rituximab 375 mg/m2 i v day 1 in cycle 1, then 1400 mg s c (or 375 mg/m2i v) days 8, 15 and 22 in cycle 1, then day 1 in cycles 3, 5, 7, 9 and 11. Maintenance phase: For patients in CR, PR or SD, not in need of other treatment, given until progression, cycle duration 56 days. Ibrutinib: 560 mg p o days 1-56, 2. Rituximab 1400 mg s c (or 375 mg/m2i v) day 1 of each cycle. Results: Accrual of 50 pts was completed in June 2016, at 10 centres in Sweden, Norway, Denmark and Finland. The median age was 69.5 years, with a median MIPI score of 6.2. Patients had received a median of two previous regimens, four had progressed after single agent ibrutinib, and three had received prior allo-SCT. A TP53 mutation was detected in 11 of 49 evaluable cases (22%), 8 cases were of blastoid/pleomorphic histology, and 22 of 40 evaluable cases had a Ki67 >30%. Treatment emergent-AEs of any grade in ≥20% of patients were rash (24%) and fatigue (20%). Five pts (10%) experienced rash grade 3, mainly during cycle 1. Hematological toxicity was generally of low grade, apart from grade 3-4 neutropenia in 5 patients. One patient died due to possible treatment-related toxicity (septic shock). In total, 27 patients achieved CR (54%) and 10 PR (20%). Among evaluable patients with a TP53 mutation, blastoid/pleomorphic histology or Ki67 >30%, the CR rates were 7/11 (64%), 15/8 (62%) and 11/22 (50%), respectively. After a median follow-up of 40 months, the median PFS is 18 months (95% CI 6.5-28), and median OS 47 months (95% CI 30-64). Patients with a detectable TP53 mutation at relapse (n=11) had a median PFS of 13 months (95% CI 4.2-21), whereas pts without a TP53 mutation had a median PFS of 34 months (95% CI 8.3-60). Of the 28 patients evaluable for MRD at 6 months, 15/27 (56%) patients achieved molecular remission in blood and 12/28 (43%) in bone marrow. After 12 months, MRD-negativity in BM was 68% (13/19). Out of 4 patients with TP53-mutated MCL, 2 were MRD-negative in BM after 12 months, as well as 2 out of 4 patients with blastoid/pleomorphic histology. By self-reported HRQOL, a lower level of emotional functioning (EF), as well as a higher level of pain (PA) at baseline, was associated with inferior PFS. In addition, low EF was associated with inferior OS. By a Cox regression multivariable analysis, including MIPI, TP53, histology, Ki67, EF and PA, only MIPI was prognostic for PFS or OS with this regimen. Conclusions: The combination of ibrutinib, lenalidomide and rituximab has been shown to be an active and well tolerated regimen in this cohort of high risk R/R MCL, associated with a high rate of molecular remission. The activity in TP53 mutated MCL is lower than in unmutated disease, but this regimen may still serve as an option for a bridge to an allogeneic transplantation or CAR-T therapy in this category of patients.

e19540 Background: Bendamustine plus rituximab (B+R) was established as a preferred first line therapy for patients with previously untreated indolent non-Hodgkin’s lymphoma based on the BRIGHT and STIL trials. However, only few reports on efficacy and safety data of this combination in the real-world setting are available to-date. Methods: We conducted a retrospective review of patients who received therapy with standard doses of B+R in our cancer center from June 2013 to January 2021. Patients with indolent non-Hodgkin’s lymphoma (iNHL) and mantle cell lymphoma (MCL) who received more than one cycle of B+R were evaluated. Results: Amongst a total of 201 patients 56% were males and 44% females. Median age at B+R initiation was 72 years (range 34-94). Follicular lymphoma (FL) (50.3%), marginal zone lymphoma (MZL) (19.4%), and lymphoplasmacytic lymphoma (LPL) (14.5%) were the most common iNHL. Stage 3 and 4 diseases represented 19.9% and 68.6% of patients. Extranodal disease was found in 35.8%. The proportion of patients with high risk disease was 48.5% for FL (FLIPI ≥3), 86.6% for LPL (WMISS score ≥2), and 80.5% for MCL (MIPI score ≥6.2). Prior history of secondary malignancy had 23.4% of patients; 11.4% patients had ECOG 3. Most common indications for B+R initiation were bulky symptomatic lymphadenopathy (69.1%), cytopenia (36.8%) and constitutional symptoms (36.8%). Fifty-eight percent of patients had more than one indication for therapy. Median number of B+R cycles delivered was 6 (range: 1-6), median dose of bendamustine was 90 mg/m2 (range 45-90). Full doses of treatment were given in 66.7% of patients, reduced in 33.3% with mean dose 78.3 mg/m2. A total of 50.8% completed 6 cycles with no delays, in 49.2% treatment was delayed (mean delay time 1.8 weeks). Overall response was 94.5%, with 77.6% complete and 16.9% partial remission. Median duration of follow-up was 35 months (range: 4-91). At the end of follow-up, event free survival (EFS) was 77.1% and overall survival (OS) was 79.6%. Six percent of patients relapsed, 8% developed secondary hematological malignancies, including 14 cases of aggressive B-cell lymphoma and 2 cases of MDS. 16.9% of patients required support with G-CSF. Grade 3-4 neutropenia was recorded in 22.4%, febrile neutropenia in 7.5%, grade 3-4 anemia in 7.9%, and grade 3-4 thrombocytopenia in 3.9% of patients. Rituximab-associated infusion reactions, skin rash, thrombophlebitis, and infection were the most common non-hematological adverse events. A total of 80.6% of patients proceeded to rituximab maintenance. Conclusions: B+R chemoimmunotherapy is feasible to administer in non-clinical trial setting. Despite more dose reduction as compared to STIL trial, B+R retained its efficacy with comparable EFS and OS. No new adverse events or increase in secondary malignancies were found.

PURPOSE In an update of the randomized, open-label, phase III European Mantle Cell Lymphoma (MCL) Elderly trial (ClinicalTrials.gov identifier: NCT00209209 ), published in 2012, we aimed to confirm results on long-term outcome focusing on efficacy and safety of long-term use of rituximab maintenance. PATIENTS AND METHODS Five hundred sixty patients with newly diagnosed MCL underwent a first random assignment between rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) and rituximab, fludarabine, and cyclophosphamide (R-FC) induction, followed by a second random assignment in 316 responders between rituximab and interferon alfa maintenance, to be continued until progression. We compared progression-free survival from the second randomization and overall survival (OS) from the first or second randomizations. RESULTS After a median follow-up time of 7.6 years, the previously described difference in OS between the induction arms persisted (median, 6.4 years after R-CHOP [n = 280] v 3.9 years after R-FC [n = 280]; P = .0054). Patients responding to R-CHOP had median progression-free survival and OS times of 5.4 and 9.8 years, respectively, when randomly assigned to rituximab (n = 87), compared with 1.9 years ( P < .001) and 7.1 years ( P = .0026), respectively, when randomly assigned to interferon alfa (n = 97). In 58% and 32% of patients treated with R-CHOP, rituximab maintenance was still ongoing 2 and 5 years from start of maintenance, respectively. After R-FC, rituximab maintenance was associated with an unexpectedly high cumulative incidence of death in remission (22% at 5 years). Toxicity of rituximab maintenance was low after R-CHOP (grade 3-4 leukopenia or infection < 5%) but more prominent in patients on rituximab maintenance after R-FC, in whom grade 3-4 leukopenia (up to 40%) and infections were frequent (up to 15%). CONCLUSION The excellent results of R-CHOP followed by rituximab maintenance until progression for older patients with MCL persisted in a mature follow-up. Prolongation of rituximab maintenance beyond 2 years is effective and safe.

PurposeThe major cause of death in aggressive lymphoma is relapse or nonresponse to initial therapy. Lenalidomide has activity in a variety of hematologic malignancies, including non-Hodgkin's lymphoma (NHL). We report the results of a phase II, single-arm, multicenter trial evaluating the safety and efficacy of lenalidomide oral monotherapy in patients with relapsed or refractory aggressive NHL.Patients and MethodsPatients were treated with oral lenalidomide 25 mg once daily on days 1 to 21, every 28 days, for 52 weeks, until disease progression or intolerance. The primary end point was response; secondary end points included duration of response, progression-free survival (PFS), and safety.ResultsForty-nine patients with a median age of 65 years received lenalidomide in this study. The most common histology was diffuse large B-cell lymphoma (53%), and patients had received a median of four prior treatment regimens for NHL. An objective response rate of 35% was observed in 49 treated patients, including a 12% rate of complete response/unconfirmed complete response. Responses were observed in each aggressive histologic subtype tested (diffuse large B-cell, follicular center grade 3, mantle cell, and transformed lymphomas). Of patients with stable disease or partial response at first assessment, 25% improved with continued treatment. Estimated median duration of response was 6.2 months, and median PFS was 4.0 months. The most common grade 4 adverse events were neutropenia (8.2%) and thrombocytopenia (8.2%); the most common grade 3 adverse events were neutropenia (24.5%), leukopenia (14.3%), and thrombocytopenia (12.2%).ConclusionOral lenalidomide monotherapy is active in relapsed or refractory aggressive NHL, with manageable side effects.

Abstract Hyper-CVAD represents an intensified program for the treatment of acute and chronic lymphoid malignancies. This protocol has been proposed as a highly efficient treatment for adult ALL with acceptable toxicity profile. Purpose: In our Institution, Hyper-CVAD was initiated in September 1999 and used as the primary treatment of adult ALL. We analyse and report here our results focusing on the efficacy and the toxicity of the program. Patients and methods: Patient population consisted of 24 de novo ALL (7 T-cell, 17 B-cell). M/F ratio was 11/13, median age 39 yrs,mean age 42,1 yrs (range 18–68 yrs). 7/24(29,1%) patients were older than 50yrs. Hyperleukocytosis of more than 100x109/L was present in 6/24(25%) cases (3 T-cell,3 B-cell), while splenomegaly, hepatomegaly and bulky disease were documented in 19/24, 17/24 and 1/24 cases respectively. Cytogenetic analysis was performed in 23/24 patients: in 11/23 it was normal, in 1/23 showed del(12), in 1/23 revealed just polyploidy and failed in 10/23 cases. Bcr-abl transcripts were detected in three cases. None of our patients presented with CNS disease (morphology & immunophenotyping). Median follow up was 12,5 months (range 1–65 mo). Treatment consisted of four cycles of Hyper-CVAD (including fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone) alternating with four cycles of methotrexate and cytarabine. All patients received intrathecal CNS prophylaxis and granulocyte stimulating factor support. Maintenance therapy consisted of two years of treatment with mercaptopurine, methotrexate, vincristine and prednisone (POMP). Imatinib was added in bcr-abl(+) cases. Results: Hematological complete remission was achieved in 21/24 (87,5%) de novo ALL cases: (11pts <4wk, 10pts >4wk ). Primary resistance was documented in 2/24 cases which subsequently received other therapeutic protocols and eventually deceased. One patient died in early induction. From the group of remmiters 11/21 are alive in CR after median DFS of 21mo (mean DFS 32mo, range 3–57). Another 7/21 remitters-including one post autologous transplantation- relapsed after median of 4,5 mo and six of them deceased. 6/21 patients underwent allogeneic transplantation (4 alive in CR, 2 deceased from complications). Regimen-related toxic deaths occurred in 4/23 cases whilst in remission status. 6/8 Τ-ALLs entered CR but half of them latter relapsed (two in consolidation and one in maintenance). CNS involvement during therapy on hyper-CVAD was not detected in the subgroup of resistant/progressive patients. Conclusions: Within the limitations of the small patient number and relatively short follow up we confirm the effectiveness of hyper-CVAD in de novo ALL, albeight at a lower than expected magnitude. Furthermore, we are unable to confirm the reported excellent outcome in T-ALL. Infectious complications were significant despite the administration of growth factors and prophylactic antibiotics. Hyper-CVAD can prevent leukemia extention to CNS in both responders and non responders.

Background: Follicular lymphoma grade 3 has a natural history that is more akin to that of diffuse large B-cell lymphoma. The addition of rituximab to standard CHOP has resulted in improved response and survival in diffuse large B-cell lymphoma. Information about outcomes in follicular lymphoma grade 3 is lacking. Methods: A single institution retrospective review of patients with follicular grade 3 lymphoma evaluated at the UTMDACC from 1999 to 2004. Patients were located from the UTMDACC lymphoma database. All patients were initially treated with R-CHOP. Results: Forty-five patients were identified: 51% male, 47% ≥60 years, and 87% follicular grade 3b. The LDH was elevated in 24%, ECOG performance status was >1 in 2%, and >1 site of extranodal involvement was present in 10%. Stage distribution was 11% stage I, 11% stage II, 42% stage III, and 36% stage IV, bulky disease (>7cm) was present in 11%, and B symptoms occurred in 13%. Beta-2 microglobulin was elevated in 57% with values >3 μg/dL in over 50%. IPI distribution was: 46% IPI Low, 38% LI, 11% IH, and 4% IPI High. Overall response rate was 100% with 96% complete responses. Relapse rate by IPI category was 24% for Low IPI, 18% for IPI LI, and 40% for IPI IH, and 100% for the two patients with High IPI. With median follow-up of 33 months, three year failure-free survival (FFS) is 73% (95% CI: 59 to 87%). One patient died (2%) with an overall survival (OS) at three years of 97% (95% CI: 93 to 100%). Conclusion: The addition of rituximab to CHOP provided a high response rate and excellent early survival in this group of mostly good prognosis patients. Relapses were still seen; longer follow-up is needed.
