Abstract INTRODUCTION Patients with high-risk aggressive B-cell lymphoma exhibit poor survival after R-CHOP-like immunochemotherapy. More intensive regimens yield higher rates of remission but also of complication, which have hindered their use, particularly in older patients. At Karolinska, the standard intensive regimen has been R-Hyper-CVAD/R-MA for patients with high-risk characteristics, such as high age-adjusted international prognostic index (aaIPI) and extranodal disease. METHODS In this analysis, high-risk disease was defined as aaIPI ≥ 2 or any extranodal involvement. We examined Karolinska's 136 patients who received at least one cycle of R-Hyper-CVAD/R-MA in first-line therapy for high-risk disease, excluding Burkitt, transformed, and primary CNS lymphoma. Patients were diagnosed between 2006 and 2020; 89 were diffuse large B-cell lymphoma, 23 high-grade B-cell lymphoma, 17 primary mediastinal B-cell lymphoma, 4 T cell/histiocyte-rich B-cell lymphoma, 2 aggressive B-cell lymphoma unspecified, 1 lymphomatoid granulomatosis grade 3. For outcome, we investigated progression-free survival (PFS). RESULTS In this cohort of 136 patients with high-risk disease treated with at least one cycle of R-Hyper-CVAD/R-MA, the median age was 52 years (range, 19-69); 36 patients (26%) were 61-69 years old. Lactate dehydrogenase was elevated in 92%, stage III-IV disease was seen in 93%, WHO performance status ≥2 in 49%, aaIPI = 3 in 38%, extranodal disease in 30%, CNS involvement in 17%, and Charlson comorbidity index ≥2 in 11%. At 5 years, the PFS in all patients was 72% and in the 50 patients with aaIPI = 3, 66% (Figure 1). In patients ≤60 years old, 5-year PFS was 76% (aaIPI = 3, 69%). In patients 61-69 years, the 5-year PFS was 58% (aaIPI = 3, 59%). Six out of 136 patients (4%) died from toxicity during induction therapy (3/6 were 61-69 years old). CONCLUSIONS This is to our knowledge the largest published single-center series of patients treated with R-Hyper-CVAD/R-MA for high-risk aggressive B-cell lymphoma. Outcome in these patients aged 19-69 years was excellent, with 5-year PFS 72%. Particularly patients with aaIPI = 3 showed rather good outcome with 5-year PFS 66%. For comparison, in Sweden the 5-year overall survival of R-CHOP-treated patients ≤60 years with aaIPI = 3 is 40% (Melén CM et al. Brit J Haematol. 614-622. 2016). We will continue to explore R-Hyper-CVAD/R-MA as primary therapy for high-risk aggressive B-cell lymphoma. Figure 1 Figure 1.

Abstract Abstract 404 Comparison of conventional chemotherapy with high-dose therapy followed by autologous stem cell transplantation (HDT/ASCT) administered to young, high-risk patients with aggressive B-cell lymphoma as part of first-line therapy gave conflicting results; none of the randomized studies used rituximab (R) in combination with conventional or HDT. In March 2003 we started a randomized phase III study for young (18-60 years), high-risk (age-adjusted IPI 2 or 3) patients with aggressive lymphoma. For patients with B-cell lymphomas this study compared 8 cycles of CHOEP-14 (CHOP + etoposide 300 mg/m2 given every 2 weeks) with MegaCHOEP. The MegaCHOEP program used cyclophoshamide (1500 mg/m2 in cycle 1; 4500 mg/m2 in cycles 2 and 3; 6000 mg/m2 in cycle 4), doxorubicin (70 mg/m2 in all cycles), vincristine (2 mg, all cycles), etoposide (600 mg/m2 , cycle 1; 960 mg/m2 , cycles 2 and 3; 1480 mg/m2, cycle 4), and prednisone (500 mg, all cycles) to be administered every 21 days. Hematopoietic stem cells were harvested after cycles 1 and 2 and reinfused after HDT cycles 2, 3, and 4. Feasibility, safety, and efficacy of MegaCHOEP + / - R have been described (Glass et al. Blood 2006 and BMT 2006). The phase III study originally had four arms (8 × CHOEP – 14, 8 × CHOEP – 14 and 6 × R, MegaCHOEP, and MegaCHOEP and 6 × R). Treatment arms without R were closed in June 2004 because other studies (e.g the MInT study) had shown major improvement in outcome parameters when R was added to chemotherapy. The study continued comparing 8 × CHOEP – 14 and 6 × R (375 mg/m2) with MegaCHOEP and 6 × R (375 mg/m2). At the time of this analysis 346 patients (pts) had been recruited; 216 pts. (median age 48 years, LDH > N 97 %, stage III or IV 96%, ECOG > 1 35%) had been randomized until 07 / 07 and were availabel for this planned interim analysis ( 8 × CHOEP – 14 + 6 × R, n = 91; MegaCHOEP + 6 × R, n = 94; 8 × CHOEP – 14, n = 15; MegaCHOEP, n = 16). Major toxicities included mucositis, diarrhea, and infections all of which were significantly more frequent in the MegaCHOEP arm of the study. Treatment – related deaths occurred in 5 / 94 pts. ( 5.3%) in the MegaCHOEP arm and in 1 / 91 pts. (1.1 %) in the R – CHOEP arm (p = 0.211). Surprisingly, the 3 – year event – free survival ( EFS : time from randomization to either disease progression, no CR / CRu at the end of treatment, initiation of salvage therapy, relapse or death from any cause) was better after conventional than after HDT / ASCT: 71.0% after 8 × CHOEP-14 + 6 × R vs. 56.7 % after MegaCHOEP + 6 × R (p = 0.050). After a median observation time of 29 months the estimated 3-year overall survival was 83.8 % after 8 × CHOEP – 14 + 6 × R and 75.3 % after MegaCHOEP + 6 × R (p = 0.142). Progression – free survival was 76.0 % after 8 × CHOEP – 14 + 6 × R and 64.6 % after MegaCHOEP + 6 × R (p = 0.119). A comparison of the rituximab-containing treatment arms (8 × CHOEP 14 + 6 × R and Mega CHOEP + 6 × R) with the chemotherapy – only arms (8 × CHOEP -14 and MegaCHOEP) revealed a 27.1 % difference in the 3-year EFS-rate ( p = 0.003 ) pointing to the unexpectedly high efficacy of R particularly in untreated, young, high-risk patients with aggressive B-NHL. These data were presented to the members of the study group and the data safety and monitoring committee who decided to stop the MegaCHOEP arm of the study. In conclusion, 8 × CHOEP -14 + 6 × R gave excellent results in young, high-risk patients with untreated aggressive B cell lymphoma. The 3-year EFS and OS are the best ever reported for this group of patients. MegaCHOEP + 6 × R was no better than aggressive conventional chemotherapy regarding any of the study endpoints; EFS (primary endpoint of the study) was significantly worse. Because of higher toxicity and inferior survival the MegaCHOEP arm was discontinued. HDT / ASCT has no role to play as part of first-line therapy for patients with high-risk aggressive B cell lymphoma if rituximab is combined with aggressive conventional chemotherapy.

Background: High-intermediate or high risk in international prognostic index (IPI) has a long-term chance of cure in the range about 50% in patients with diffuse large B cell lymphoma (DLBCL) treated by R-CHOP. These high risk patients should be considered for additional new treatment to standard R-CHOP or investigational approaches in the context of clinical trials that are designed to ensure that potentially curative therapy. Bortezomib inhibits NF-κB activation through proteasome inhibition, providing rationale for its use in cells that constitutively express NF-κB. Non-germinal center B cell (GCB) DLBCL has a worse survival after upfront chemotherapy and is characterized by constitutive activation of the antiapoptotic NF-κB pathway, which can inhibit chemotherapy. There is no study of bortezomib as maintenance therapy after treated with R-CHOP in high risk patients with DLBCL. So we applied additional bortezomib as maintenance therapy in order to assess improving efficacy and survival rates in high risk patients with non-GCB DLBCL who had been confirmed complete response (CR) after treated with R-CHOP. Methods: Patients with newly diagnosed stage II(bulky)-IV DLBCL with high or high intermediate IPI score of 3 to 5, and patients achieving a CR at the end of 6 or 8 cycles of R-CHOP21 were eligible for enrollment. Non-GCB DLBCL according to Hans criteria confirmed by central review was need before enrollment. Bortezomib maintenance treatment was consisted of bortezomib 1.3mg/m2 subcutaneously administration day 1 and day 15 per 28-day cycle with a total of 12 cycles. The primary endpoint was 3-year progression-free survival (PFS). Secondary endpoints were 3-year overall survival (OS), and toxicites. Toxicity was graded according to the Common Terminology Criteria for Adverse Events v4.0. Results: Fifty-nine patients were enrolled between May 2014 and Oct 2018. The type of Non-GCB DLBCL in all patients was confirmed by the central pathology review. The median age was 65 years (range: 27-86 years), and 60% were > 61 years. The baseline clinical features were as follows: female sex, 45.8%; ECOG >1, 10.2%; stage II bulky (>10cm), 6.8%; stage III/IV, 93.2%. At the time of analysis, 29 patients completed 12-cycles of bortezomib maintenance, and 3 patients is ongoing. Seven patients did not finished maintenance therapy due to toxicities (fatigue, atrial flutter, neuropathy, pleural effusion, thrombocytopenia), and withdrawal of informed consent (n=4). Sixteen patients experienced disease progression during bortezomib maintenance treatment. With a median follow-up of 25.1 months, 3-year PFS rate was 56.9% and 3-year OS rate was 86.4% (Figure 1). Toxicity was assessed in 489 cycles of bortezomib maintenance in all 59 patients. There was no treatment-related death and febrile neutropenia. Conclusion: Bortezomib maintenance showed 3-year PFS rate of 56.9% with acceptable toxicities in patients with high risk DLBCL achieving a CR at the end of 6 or 8 cycles of R-CHOP21.

Abstract Abstract 663 Background: The majority of patients with relapsed or refractory B-cell, non-Hodgkin's lymphoma (NHL) are over 60 years of age, yet many are denied potentially curative high-dose regimens due to concerns of excessive toxicity. We have shown that myeloablative anti-CD20 radioimmunotherapy (RIT) can safely deliver effective radiation doses to tumor sites while limiting exposure to normal organs in older adults requiring high-dose therapy, however, not all patients in this series remained progression-free (Gopal, JCO 2007). Preclinical data suggest that improved anti-tumor activity may be attained by the concurrent administration of nucleoside analogs (fludarabine, cytarabine) which synergize with RIT (Johnson, Int J Cancer; Gopal, BBMT, 2006). We hypothesized that a prolonged regimen of fludarabine could be administered concurrently with myeloablative RIT and ASCT to safely augment the efficacy of this approach. We present the phase I data evaluating this strategy. Methods: Patients were eligible if they were 60 years of age or older, had mantle cell lymphoma (MCL) in first remission or relapsed/refractory B-NHL, an ECOG PS of 0–1, acceptable organ function, >2×106 autologous CD34+ peripheral blood stem cells/kg collected, <20 Gy prior radiation to critical organs, and no human-anti-mouse-antibodies (HAMA). All patients underwent outpatient biodistribution studies for dosimetry using tositumomab (1.7 mg/kg, n=3 or 485mg flat dose, n=33) labeled with ∼10mCi I-131 followed by serial quantitative gamma camera imaging to calculate individualized organ-specific absorbed dose estimates. Patients then received therapeutic infusions of I-131-tositumomab to deliver 27Gy to the critical normal organ receiving the highest radiation exposure. Forty-eight hours later fludarabine was administered in escalating doses to patients (Table) to define a regimen associated with a dose limiting toxicity (DLT = grade III/IV Bearman toxicity) rate of <25%. ASCT occurred when radiation exposure was estimated to be <2mR/hr at 1meter. Filgrastim at 5μg/kg/day or pegfilgrastim at 6mg × 1 was started on day 1. Response was scored using standard criteria. Results: Between July 2005 and May 2011 36 patients were treated. Baseline characteristics included: median age 65 yrs (range 60–76), stage III/IV = 34 (94%), median number of prior regimens = 2 (range 1–9), chemoresistant disease (defined as < a partial response [PR] to the most recent regimen) = 12 (33%), >1 extranodal site = 14 (39%), elevated LDH at treatment = 13 (36%), IPI score at transplant 3–5 = 53%. Histology: MCL = 23, diffuse large B-cell = 8 (with 5 transformed from follicular lymphoma [FL]), FL=3, and marginal zone = 1, Waldenstrom's = 1. Dose limiting organs receiving up to 27Gy included lung (30), kidney (4), and liver (2) with a median administered I-131 activity of 471 mCi (range 260–1620). Fludarabine was escalated from 10 mg/m2/day × 5 days to 30 mg/m2 × 7 days without observation of a DLT (Table). The median CD34 dose was 5.42 ×106/kg with neutrophil (ANC>500μl) and platelet (>20 K/μl) engraftment occurring a median on 10 and 12 days after ASCT, respectively. Only 2 patients developed grade 4 NCI-CTC grade 4 non-hematologic toxicities (hypokalemia/hypophosphatemia, depression), 25 (69%) remained outpatients after discharge from radiation isolation, and there were no non-relapse deaths in the first 100 days after transplant. Responses to therapy were as follows: CR/CRu = 26 (79%), PR = 2 (6%), SD = 4 (11%), and PD = 4 (11%). Currently, 23 (64%) patients are alive with 22 (61%) progression free. The estimated 3 yr overall survival, progression-free survival, relapse, and non-relapse mortality are 54%, 53%, 41%, and 7%, respectively (median follow up of 2.5yrs after ASCT, Figure). Improved survival was associated with <2 prior regimens (HR=.08, p=.02) and chemosensitive disease (HR=.35, p=.07). Conclusions: High-dose (27 Gy) I-131 tositumomab can safely be administered concurrently with up to 210 mg/m2 fludarabine in an older, high-risk patient population. This strategy warrants further investigation as a method to safely augment the antitumor activity of myeloablative RIT.

Abstract Background. Survival of patients with high-risk diffuse large B-cell lymphoma (DLBCL) is suboptimal, and the risk of central nervous system (CNS) progression is relatively high. We investigated the efficacy of dose-dense chemoimmunotherapy and systemic CNS prophylaxis in two Nordic trials including patients less than 65 years with high-risk DLBCL. We combined individual patient data from these trials to compare clinical outcome and biological prognostic factors in patients treated with CNS prophylaxis given in the beginning (CHIC) versus at the end (CRY-04) of therapy. Patients and methods. In CRY-04 study, patients were treated with six courses of R-CHOEP14 followed by HD-Mtx and HD-Ara-C. In CHIC trial, treatment started with two courses of HD-Mtx in combination with R-CHOP14, followed by four courses of R-CHOEP-14 and one course of R-HD-AraC. In addition, liposomal AraC was administered intrathecally at courses 1, 3 and 5. For the correlative studies, formalin fixed paraffin embedded pretreatment tumor samples were analyzed by fluorescent in situ hybridization for BCL2 and c-MYC breakpoints and by immunochemistry for CD10, BCL6, MUM1, MYC and BCL2 expression. Germinal center B-cell-like (GCB)/non-GCB) subclassification was performed according to Hans algorithm. Results. Among 303 patients enrolled in the trials (CRY-04, n=160 and CHIC, n=143), 295 (CRY-04, n=154 and CHIC, n=139) were evaluable for baseline characteristics and outcome. Median age (54 and 56 years, p=0.222), male/female ratio, stage, and aaIPI scores were comparable in the two cohorts. CHIC regimen improved outcome over CRY-04; the findings included 4-year estimates of PFS (81% vs 66%, p=0.003), OS (83% and 79%, p=ns) and cumulative incidence rates of CNS progression (2.4% and 5.0%, p=ns). Treatment with the CHIC regimen reduced the risk of systemic progression (aaIPI adjusted RR=0.489, 95%CI 0.308-0.777, p=0.002). PFS benefit with CHIC over CRY-04 was observed across pre-specified subgroups, and particularly in patients less than 60 years old (p=0.008). In the entire study population, dual protein expression (DPE) of BCL2 and MYC was the only parameter to be significantly correlated with a worse PFS (4-y PFS 77% vs 50%, p=0.024; RR=2.300, 95% CI 1.088-4.860, p=0.029). Neither any single immunohistochemical marker nor the GCB/non-GCB subtype or MYC/BCL2-translocations significantly affected outcome. However, when treatment interaction was tested, MYC/BCL2 double hit status (DHL; 13%) predicted poor outcome among patients treated with CRY-04 regimen compared with patients who received CHIC regimen (4-y PFS; 38% vs 78%, p=0.086). GCB subtype and BCL2 positivity were also associated with better outcome in the CHIC cohort (4 y PFS; 63% vs 84%, p=0.011 and 61% vs 80%, p=0.007, respectively), whereas there were no significant survival differences between these regimens among the patients with non-GCB subtype, BCL2 negative DLBCL or DPE lymphomas. Conclusions. Our results derived from trial data with homogenous treatment support the use of HD-Mtx in the beginning rather than at the end of therapy. The survival benefit related to CHIC regimen over CRY-04 is due to better systemic control of the disease, and at least partly linked to improved survival among patients with GCB subtype, BCL2 positivity and DHL.

Introduction:Considering the increasing numbers of lymphoma patients (pts) surviving long-term, late effects of current treatment strategies such as secondary (sec) malignancies gain increasing importance. Many treatment regimens used in pts with lymphoma (R-CHOEP, DA-EPOCH-R, BEACOPP) include etoposide, a cytotoxic agent reported to increase sec leukemias. In order to further investigate the role of etoposide in inducing sec malignancies in pts with aggressive lymphoma we analyzed the R-MegaCHOEP trial (Schmitz et al., Lancet Oncology 2012) where young, high-risk pts with aggressive B-cell lymphomas had received R-CHOEP or R-MegaCHOEP, a regimen containing very high doses of etoposide (4g/m2). We compared rates of secondary tumors to incidences found in young patients treated with R-CHOP only. Methods:We analyzed 1536 pts aged 18-60 years with aggressive B-cell lymphoma treated in the prospective phase 3 trials FLYER (NCT00278421; n=588, median observation time (OT)=66 months), UNFOLDER (NCT00278408; n=695, median OT=72 months) and MegaCHOEP (NCT00129090; n=253, median OT=112 months) to compare the cumulative incidences of sec neoplasms. We performed a competing risk analysis for time from randomization to occurrence of sec malignancy (myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) or other) according to first-line therapy with R-CHOP (n=1283) vs. R-CHOEP (n=127) vs. R-MegaCHOEP (n=126). We used a cause-specific hazard model adjusted for gender, age (&gt;50 vs. &lt;= 50 years) and radiotherapy. Results:Adjusting for competing events, we found sec MDS/AML in 0.3% of pts treated with R-CHOP, in 1% of pts treated with R-CHOEP and in 2% of pts following treatment with R-MegaCHOEP. Cause-specific hazard ratios showed a trend for increased risk for sec AML following R-MegaCHOEP in comparison to R-CHOP (HR 5.2, 95%CI (1.0; 27.5), p=0.052) while R-CHOEP did not significantly increase the incidence of sec AML (HR 1.4, 95%CI (0.1; 14.0), p=0.777). Male gender and age &gt;50 years showed a trend for increasing sec AML. We found very similar incidences of sec solid tumors (not MDS/AML) affecting 4% of pts treated with R-CHOP or R-MegaCHOEP and 6% of pts following R-CHOEP regimen. The only factor significantly increasing the risk of sec solid tumors was age &gt;50 years (HR 2.6, 95%CI (1.5; 4.3), p&lt;0.001). Conclusions:This analysis shows that sec malignancies represent rare events in younger patients with aggressive B-cell lymphoma, even after extreme dose-escalation of etoposide. Compared to standard R-CHOP, 8 cycles of R-CHOEP were not associated with increased risk of sec AML or solid tumors thus remaining an attractive first-line treatment for young high-risk pts with DLBCL.

Introduction: Venetoclax, a BCL2 inhibitor, has demonstrated efficacy both as a single agent and in combination with rituximabin several subtypes of B-cell non-Hodgkin lymphoma (NHL). The combination of obinutuzumab and lenalidomide has demonstrated safety and preliminary efficacy in follicular lymphoma (Fowler et al., JCO 2015; 35: 7531). We conducted a phase I study of obinutuzumab, venetoclax, and lenalidomide to determine the safety, maximum tolerated dose, and preliminary efficacy of the combination. Methods: Patients with relapsed/refractory diffuse large B-cell (DLBCL), transformed, high grade B-cell (HGBCL), marginal zone, and follicular (FL) lymphoma who have received ≥ 1 prior therapy were eligible. Prior autologous (ASCT) but not allogeneic stem cell transplant were permitted. Prior lenalidomide or BCL2 family inhibitors, CNS involvement, and active hepatitis or HIV infection were not permitted. ANC > 1000/mm3, platelets > 75,000/mm3, creatinine clearance ≥50 ml/min, ALT/AST ≤ 3 x ULN, bilirubin ≤ 1.5 x ULN, and ECOG PS 0-2 were required. Treatment consisted of obinutuzumab 1000 mg on days 1, 8 and 15 of cycle 1 and then on day 1 of cycles 2-6 with escalating doses of lenalidomide days 1-21 and venetoclax days 1-28 of a 28 day cycle (Table 1). A 3+3 dose escalation schema was followed. The DLT period was 1 cycle and patients had to receive 80% of the doses of the oral agents and all doses of obinutuzumab to be considered evaluable for DLT. DLTs included: treatment delays > 28 days; ANC < 500 / mm3 or platelets <25, 000 / mm3 persisting > 28 days; grade 4 febrile neutropenia or infection; grade 3 infection that fails to resolve within 7 days; and grade 3 or 4 non-hematologic toxicity. Patients without significant toxicity or progression could continue treatment up to 12 cycles. Response was assessed by CT or PET/CT every 3 months for 12 months and then every 6 months until disease progression. Results: 22 patients were treated. Median age was 61 years (range 31-78 years) with 16 males. Median prior therapies was 2 (range 1-10) and included 5 patients who had relapsed after chimeric antigen receptor T-cell therapy and 2 patients relapsed after ASCT. Median baseline lactate dehydrogenase was 259.5 U/L (range 147-5133, ULN 190 U/L). 16 patients had aggressive B-cell lymphoma including DLBCL, HGBCL, primary mediastinal and transformed FL, 5 patients had FL and 1 patient had marginal zone lymphoma. At dose level (DL) 1, one patient experienced a DLT, grade 3 neutropenic fever lasting > 7 days. DL 1 was expanded and no additional DLTs occurred. No further DLTs occurred at DL 2-4. DL 4 was expanded and was determined to be the MTD. Four patients, 1 in each dose level, were not evaluable for DLT and were replaced including 3 who did not receiving 80% of the oral agents due to required dose reductions and 1 patient for disease progression. Related grade 3-4 toxicities were primarily hematologic including neutropenia (n=20, 90.9%), thrombocytopenia (n=5, 22.7%), and anemia (n=3, 13.6%). Grade 3-4 infections (n=6, 27%) included sepsis, febrile neutropenia, pneumonia and a urinary tract infection. Other grade 3-4 AEs occurring once each included dysgeusia, dyspnea, nausea, vomiting, and hyperhidrosis. No clinically significant tumor lysis has occurred. Patients have received a median of 3 cycles (range 1-12) of treatment. Three patients remain on therapy and 5 patients are on follow up. Dose reductions of lenalidomide occurred for 17 patients (77%) and of venetoclax for 11 patients (50%). Nine patients have achieved a response (41%), including 8 complete (CR) and 1 partial responses (PR). Responses have occurred at each DL and include 4 patients with FL (2 CR, 2 PR), 4 patients with aggressive lymphoma (4 CR) and 1 patient with MZL (CR). 14 patients are off of the study, 9 with progression, 2 for alternative therapy, and 1 each for DLT, physician preference, and a diagnosis of MDS in a patient with 3 prior lines of chemotherapy. Conclusions: Combined treatment with obinutuzumab, venetoclax, and lenalidomide administered up to 12 cycles is feasible with activity in multiple subtypes of relapsed NHL. Enrollment in expansion cohorts of FL and aggressive B-cell lymphoma is ongoing.

Abstract Abstract 689 Background: Lenalidomide was demonstrated to have significant single agent activity in relapsed aggressive B cell lymphoma (J Clin Oncol. 2008;26:4952–7, Ann Oncol. 2011;22:1622–7). In a phase I study, we previously demonstrated that Lenalidomide 25 mg day 1–10 of the cycle can be combined with RCHOP21 and this combination does not result in dose delays or increased toxicity (Leukemia 2011;12:1877–81). We now present phase 2 results of R2CHOP in treatment of patients with aggressive B-cell lymphoma. Methods: Eligible patients were adults with newly diagnosed CD20 positive diffuse large B cell (DLBCL) or grade 3 follicular lymphoma (FL). The response was evaluated using PET/CT by standard criteria (J Clin Oncol. 2007;25:579–586). The progression free survival (PFS) was defined as time from diagnosis to disease progression or death. Results: 51 patients - 6 enrolled at the MTD in phase 1 portion of the study and 45 in phase 2 portion were included in the analysis. The median age was 65 years (range, 19–87). 35% of patients were 70 and older. 63% (32/51) were males. 47 patients (92%) had DLBCL and 4 (8%) patients had FL grade 3. The international prognostic index (IPI) was low, low-intermediate, high-intermediate and high in 8 (15%), 18 (35%), 18 (35%) and 7 (14%) patients respectively. 31 patients (60%) had stage 4 disease. Hematological toxicities were: grade 3 and 4 thrombocytopenia (20% and 20% of patients respectively); grade 3 and 4 neutropenia (18% and 71% of patients respectively). Overall 27% of patients experienced a grade 3 or higher non-hematological toxicity at least possibly related to treatment. The most frequent were febrile neutropenia (10%), nausea (4%), urinary tract infection (4%), vascular access complication (4%), and dehydration (4%). 1 patient (2%) developed thrombosis. There was one death (2%) secondary to bowel perforation/sepsis. For 47 patients evaluable for response, the overall response (ORR) and complete response (CR) rates were 98% and 83% respectively. The PFS was 73% at 12 months (Figure). Since the enrolled patients represented a relatively high-risk group (49% intermediate high or high IPI, significant proportion of elderly male patients), the PFS in R2CHOP was compared to PFS in a contemporary cohort of 87 consecutive patients with DLBCL participating in Mayo Clinic Lymphoma Database and treated with standard RCHOP alone. The PFS was 62% at 12 months in this cohort and was inferior to R2CHOP (Figure). Conclusion: Lenalidomide combined with standard R-CHOP21 chemotherapy (R2CHOP) demonstrates predictable safety profile. The ORR and CR rates and PFS are encouraging in elderly high IPI patients, and compared favorably to the R-CHOP treated historical cohort with similar clinical characteristics. A randomized trial will be needed to confirm the benefits of this novel combination. Disclosures: Off Label Use: lenalidomide in treatment of NHL. Reeder:Celgene: Research Funding.
