7504 Background: MCL is a non-Hodgkin lymphoma with heterogeneous biology and outcomes. We characterized RW tx patterns and outcomes of MCL pts to identify factors associated with outcomes in the US. Methods: This retrospective study included adult MCL pts diagnosed Jan 2011-Nov 2020 in the nationwide Flatiron Health EHR-derived deidentified database. Pt characteristics, tx patterns, time to next tx (rwTTNT, defined as start of first-line [1L] tx to subsequent tx or death) and rwOS were evaluated. Results: 3455 pts were included, 85.3% from a community oncology setting. In 2946 (85.2%) pts with documented 1L MCL tx, median age was 69.5 y (range 27.7-85.3); 9.5% had blastoid/pleomorphic MCL. 262 (39.6%) and 235 (35.6%) of 661 pts with available MCL international prognostic index (MIPI) had intermediate and high risk, respectively. 150/1253 pts (12.0%) with available ECOG PS had PS ≥ 2. Chemoimmunotherapy was the most common 1L tx, including BR in 1223 (41.5%), R-CHOP in 512 (17.4%) and cytarabine (ara-C)-containing tx in 414 (14.1%). 667 pts received R maintenance (MR). In 1036 pts < 65 y, 243 pts received 1L stem cell transplant (SCT), mainly autologous. In 1L-treated pts, with median follow-up of survivors of 45.3 mos (range 0.03-117.2), median rwTTNT was 24 mos; 36-mo rwOS was 67%. The Table shows tx received and outcomes by age and SCT status. MVA analyses showed age ≥ 65 y, ECOG PS ≥ 2, LDH/ULN ≥ 1, WBC ≥ 10 × 109/L, bulky disease (≥ 5 cm) and blastoid/pleomorphic morphology were associated with shorter rwTTNT and rwOS; MR was independently associated with longer rwTTNT and rwOS. In pts < 65 y who were alive and did not initiate subsequent tx within 6 mos of 1L tx (“SCT-eligible”), 36-mo rwTTNT and rwOS were similar between pts treated with vs without SCT: 65% vs 59% and 86% vs 85%, respectively. Conclusions: In this large RW cohort of primarily community-based US practices, median 1L rwTTNT for MCL pts was ̃ 2 y. BR was the most commonly used 1L tx. SCT was uncommon even in pts < 65 y, suggesting RW considerations may influence SCT eligibility and availability. Also, SCT was not clearly associated with rwOS. As with other reports, older age and high-risk disease features were predictive of worse outcome in RW, while MR appeared to be associated with better outcomes. Outcomes across the board appear worse than prospective trials, suggesting a need to focus on developing tx that can be delivered effectively in the community setting.[Table: see text]

AbstractPrimary gastrointestinal (GI) mantle cell lymphoma (MCL) is rare and the optimal management is unknown. We reviewed 800 newly diagnosed MCL cases and found 22 primary (2.8%) and 79 (9.9%) secondary GI MCL cases. Age, sex, and performance status were similar between primary and secondary cases. Secondary cases had more elevations in lactate dehydrogenase (28% vs 0%, P = 0.03) and a trend for a higher MCL international prognostic index (P = 0.07). Observation or local therapy was more common for primary GI MCL (29% vs 8%, P < 0.01), and autologous stem-cell transplant was more common for secondary GI MCL (35% vs 14%, P < 0.05). The median follow-up was 85 months. Primary and secondary GI MCL had similar 5-year progression-free survival (PFS) (30% vs 28%, P = 0.59) and overall survival (OS) (65% vs 66%, P = 0.83). The extent of GI involvement in primary GI MCL affected treatment selection but not outcome, with a 5-year PFS of 43% vs 14% vs 31% (P = 0.48) and OS of 57% vs 71% vs 69% (P = 0.54) in cases with single lesion vs multiple lesions in 1 organ vs multiple lesions in ≥2 organs. Less aggressive frontline treatment for primary GI MCL is reasonable. It is unknown whether more aggressive treatment can result in improved outcomes.

7540 Background: Tafasitamab is a humanized, Fc-modified anti-CD19 monoclonal antibody that enhances antibody-dependent cellular cytotoxicity and phagocytosis. It is FDA-approved with LEN for adult patients (pts) with relapsed/refractory (R/R) DLBCL ineligible for autologous stem cell transplantation. First-MIND (NCT04134936) is a Phase Ib, open-label, randomized study of tafa + R-CHOP or tafa + LEN + R-CHOP in newly diagnosed DLBCL. Methods: Eligible pts were ≥18 years, treatment-naïve, with histologically confirmed DLBCL not otherwise specified, international prognostic index (IPI) 2–5 and ECOG performance status (PS) 0–2. Pts with known double- or triple-hit and transformed lymphoma were excluded. Treatment (Tx) comprised six 21-day cycles of tafa (12 mg/kg IV, Day [D] 1, 8, 15) + R-CHOP (arm A) or tafa (12 mg/kg IV, D1, 8, 15) + LEN (25 mg orally, D1–10) + R-CHOP (arm B). G-CSF and VTE prophylaxis was mandatory. Primary objective is safety; secondary objectives are ORR, PET-CR rate at end of Tx, PFS, long-term safety, pharmacokinetics, immunogenicity. Results: From Dec 2019 to Aug 2020, 83 pts were screened in Europe and the US; 66 were randomized (33 per arm). Data cut-off for this analysis: 9 Dec 2020; study is ongoing. Median age was 64.5 years (range 20–86). Overall, 30% (20/66) of pts were ≥70 years and many had high-risk disease: IPI 2 29%, IPI 3 46%, IPI 4 26%. ECOG PS: 47% of pts were ECOG PS 0, 44% PS 1, 9% PS 2. Most pts had stage III/IV disease (92%); 46% had bulky disease. All pts experienced a treatment-emergent adverse event (TEAE). Grade ≥3 neutropenia and thrombocytopenia occurred in 54.5% and 12.1% (arm A) and 66.7% and 30.3% (arm B) of pts, respectively (Table). Serious TEAEs occurred in 42.4% (arm A) and 51.5% (arm B) of pts. There were three deaths, unrelated to tafa and/or LEN (sepsis, urosepsis, and COVID-19 pneumonia). R-CHOP dose intensity was maintained in both arms. Among 60 pts who completed tumor assessments after cycle 3, ORR was 89.7% (arm A) and 93.5% (arm B). Conclusions: These data suggest R-CHOP + tafa or tafa + LEN is tolerable in pts with Tx-naïve DLBCL and that R-CHOP dosing is not affected. Toxicities are similar to those expected with R-CHOP or R-CHOP + LEN. Updated safety and early efficacy data will be presented at the conference. Clinical trial information: NCT04134936.

Abstract Rituximab-containing chemotherapy regimens constitute standard first-line therapy for mantle cell lymphoma (MCL). Since June 2013, 190 patients ≥18 years of age with MCL in British Columbia have been treated with bendamustine and rituximab (BR). The overall response rate to BR was 88% (54% complete response). Of these, 61 of 89 patients (69%) aged ≤65 years received autologous stem cell transplantation and 141 of 190 patients (74%) from the entire cohort received maintenance rituximab. Twenty-three patients (12%) had progressive disease, associated with high risk per the Mantle Cell Lymphoma International Prognostic Index (MIPI), Ki-67 ≥50%, and blastoid/pleomorphic histology. Outcomes were compared with a historical cohort of 248 patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; January 2003 to May 2013). Treatment with BR was associated with significant improvements in progression-free survival (PFS), but not overall survival (OS), compared with R-CHOP in the whole cohort (3-year PFS, 66% BR vs 51% R-CHOP, P = .003; 3-year OS, 73% BR vs 66% R-CHOP, P = .054) and in those &gt;65 years of age (3-year PFS, 56% BR vs 35% R-CHOP, P = .001; 3-year OS, 64% BR vs 55% R-CHOP, P = .063). Outcomes in transplanted patients were not statistically significantly different compared with R-CHOP (3-year PFS, 85% BR vs 76% R-CHOP, P = .135; 3-year OS, 90% BR vs 88% R-CHOP, P = .305), although in multivariate analyses, treatment with BR was associated with improved PFS (hazard ratio, 0.40 [95% confidence interval, 0.17-0.94]; P = .036) but not OS. BR is an effective first-line option for most patients with MCL, however, outcomes are suboptimal for those with high-risk features and further studies integrating novel agents are warranted.

Abstract Introduction: The clinical course of MCL is characterized by a continuous pattern of relapse and a poor long term outcome with a median Overall Survival (OS) of four years and a 15% of long term survivors. Recently a new clinical prognostic score (MIPI), including performance status, age, LDH level and leukocyte count has been reported. This score allows a more reliable estimation of individual clinical course. We retrospectively applied the MIPI score to patients with MCL. Patients and methods: Between 1999 and 2007, 40 patients with MCL diagnosed and treated in a single institution entered into the study. Clinical characteristics were as follows: median age 56 years (range 37–81), 80% male; 82% stage IV; 78% bone marrow involvement and 15% MCL with blastoid variant. First line treatments were: high dose chemoimmunotherapy including Rituximab (R) with autologous stem cell transplantation (R-HDC) in 26 patients and Rituximab-CHOP like chemotherapy (R-CHOP) in 14. Crude Kaplan-Meier OS and progression-free survival (PFS) curves were estimated both overall and stratified by MIPI and International Prognostic Index (IPI) score. Differences between curves were tested using the 2-tailed log-rank test. In order to quantify the predictive discrimination of MIPI and IPI scores, univariate logistic models (with death and progression event as binary outcomes) were fitted and the area under the receiver operating characteristic (ROC) curves (c index) was estimated. Results: According to MIPI score 17 patients (43%) were at low risk (LR, score 0–3), 13 patients (32%) at intermediate risk (IR, score 4–5) and 10 patients (25%) at high risk (HR, score &gt;5). According to IPI score 14 patients (35%) were at low risk (LR), 16 patients (40%) at low-intermediate risk (LIR) and 10 patients (25%) at intermediate-high and high risk (IH-HR). At the end of the treatment, 30 patients achieved a CR, five a PR and five did not respond. Relapses occurred in 17 patients and seven of them died of lymphoma. With a median follow-up (FU) of 29 months, OS was 85% (95% CI: 66%–93%); with a median FU of 21 months, PFS was 70% (95% CI: 51%–83%). Twenty-nine months OS rates for MIPI score were: LR 100%, IR 81%, HR 66% respectively (p=.07) and for IPI score were: LR 92%, LIR 94%, IH-HR 65% respectively (p=.09). Twenty-one months PFS rates for MIPI score were: LR 92%, IR 59%, HR 45% respectively (p=.006) and for IPI score were: LR 73%, LIR 87%, IH-HR 44% respectively (p=.09). MIPI score was more predictive than IPI score for the death event and for the progression event: the c index was 74% and 73% for MIPI compared to 72% and 69% for IPI respectively. In a subgroup analysis performed on 26 R-HDC patients, OS and PFS rates stratified for MIPI were: for OS, LR 100% vs IR 80% vs HR 69% (p=.4) and for PFS, LR 91% vs IR 80% vs HR 57% (p=.04) respectively. Discussion: in our retrospective series of patients, MIPI prognostic score discriminates among patients with different PFS. Relapses remain the most important issue for all patients affected by MCL, namely in HR group according to MIPI. New therapeutic strategies are warranted to improve the prognosis of MCL.

Abstract Introduction Histologic transformation of low grade non Hodgkin lymphoma (LG-NHL) occurs with a variable frequency. Several factors have been associated with survival in transformed lymphoma (TL) and the prognosis has been generally poor. The R-IPI has been shown to be prognostic in the pre rituximab era. Purpose To assess R-IPI as prognostic at lymphoma transformation in the rituximab era. Methods Patients with a diagnosis of diffuse large B-cell lymphoma transformed from LG-NHL (DLBCL-TL) were identified between January 2001 and December 2011 through the Moffitt Cancer Center Total Cancer Care Database. LG-NHL included follicular lymphoma (FL), marginal zone lymphoma (MZL), mucosa associated tissue lymphoma (MALT) and other low grade histologies. Patients with small lymphocytic lymphoma (SLL) with Richter’s transformation were excluded. All patients received rituximab based chemotherapy at transformation. Clinical data, pathologic data include morphology and immunohistochemistry (IHC) including CD10, BCL6, MUM1/IRF4 were recorded. Overall survival (OS) was calculated from the date of transformation. OS was estimated by the Kaplan-Meier method and compared using the long-rank test. A p-value< 0.05 was considered statistically significant. Results A total of 81 patients were identified with DLBCL-TL. At diagnosis and transformation the median ages were 60 and 64 years (22 – 89), respectively. The male:female ratio was 0.72. The most common LG-NHL diagnosis was FL (75.3%). The median time to DLBCL transformation (TTT) was 3.4 years. At LG-NHL diagnosis 67.9% of patients were stage III/IV, 23.5% had bulky disease, 35.8% had extranodal disease (ED) and 14.8% were FLIPI1 score > 3. At transformation 29.6% had B symptoms, 77.8% had stage III/IV disease, 25.9% had ED, and 40.4% had an elevated LDH. DLBCL-GCB as per Hans algorithm was present in 65.5% of cases at transformation. The mean hemoglobin (Hb) and serum albumin (SA) level at transformation were 12.6 g/dl and 3.9 g/dl, respectively and an IPI > 3 was present in 22.2% of cases. R-IPI categories were very good in 4.9%, good in 72.8% and poor in 22.2%. Patients received rituximab prior to transformation in 65.4% with R-CHOP being the most common regimen used (84%). Radioimmunotherapy (RIT) was given in 17.3% of patients. Patients received 3 or more treatment lines in 74.1%. Patients underwent autologous and allogeneic stem cell transplant in 24.7 and 2.5% of cases, respectively. The median OS was 6.2 years. Poorer OS was associated with R-IPI > 3 at transformation (median OS 1.9 y, HR 2.9 [CI 1.5 – 5.9], p<0.0001) (Figure 1), FLIPI1 score 3 or more (median OS 1.7y, HR 2.9 [CI 1.7 – 5.1], p<0.0001), TTT< 2 years (median OS 2.8y, HR 3.2 [0.9 – 10.5], p=0.041), B symptoms (median OS 2.8y, HR 3.1 [1.5 – 6.4] p=0.003) and elevated LDH (median OS 2.8y, HR 2.6[1 – 6.6], p=0.04). The median OS with IPI< 2 was not reached. No survival differences were seen with FL vs non FL histology, older age, extranodal disease, bulky disease, use of RIT, number of treatment lines or rituximab prior to TL. There was a trend towards poorer OS with SA< 3.7 g/dl (median OS 2.8y, p=0.068). Conclusions An R-IPI >3 at transformation was associated with poorer OS in patients with LG-HNL who undergo histological transformation into DLBCL and treated with chemoimmunotherapy. This suggests that R-IPI can be used at the time of transformation to better assess the aggressiveness of disease. A confirmation of these findings will be needed in multicenter and prospective cohorts. Disclosures: No relevant conflicts of interest to declare.

Purpose The combination of bendamustine (B) and rituximab (R) is efficacious, with favorable toxicity in mantle-cell lymphoma (MCL). In this phase II study, we combined cytarabine with R and B (R-BAC) in patients with MCL age ≥ 65 years who were previously untreated or relapsed or refractory (R/R) after one prior immunochemotherapy treatment. Patients and Methods In stage one, we established the maximum-tolerated dose (MTD) of cytarabine in R-BAC. In stage two, patients received R (375 mg/m2 intravenously [IV] on day 1), B (70 mg/m2 IV on days 2 and 3), and cytarabine (MTD IV on days 2 to 4) every 28 days for four to six cycles. The primary end point (overall response rate [ORR]) was evaluated by positron emission tomography. Secondary end points included safety, progression-free survival (PFS), response duration, and overall survival. Results Forty patients (median age, 70 years; 20 previously untreated patients) were enrolled; 93% had Ann Arbor stage III/IV disease; 49% had high Mantle Cell International Prognostic Index scores, with 15% blastoid histology. All R/R patients (35% refractory) had previously received R-containing regimens. The cytarabine MTD used in stage two was 800 mg/m2, and R-BAC was well tolerated, with an 85% treatment completion rate. The major toxicity was transient grades 3 to 4 thrombocytopenia (87% of patients); febrile neutropenia occurred in 12%. The ORR was 100% (95% complete response [CR]) for previously untreated and 80% (70% CR) for R/R patients. The 2-year PFS rate (± standard deviation) was 95% ± 5% for untreated and 70% ± 10% for R/R patients. Conclusion R-BAC is well tolerated and active against MCL.

Abstract Abstract 2703 Poster Board II-679 Introduction: Mantle cell lymphoma (MCL) is an incurable disease with a highly variable course. Improvements in therapy have been impeded by the lack of a universal prognostic model, making risk stratification and comparisons across clinical trials difficult. The International Prognostic Index (IPI) and Follicular Lymphoma International Prognostic Index (FLIPI) have been applied but show limitations in MCL, especially in distinguishing low and intermediate-risk patients (pts). The MIPI (Mantle Cell International Prognostic Index) was developed to overcome these limitations, and is based on WBC, age, and LDH (analyzed as continuous variables) and ECOG performance status.1 However, the MIPI has yet to be independently validated, and failed to predict outcome of MCL pts treated with Hyper-CVAD.2 To examine the prognostic capacity of the MIPI, we reviewed outcomes of pts diagnosed with MCL from 1998–2008 at the Cleveland Clinic Taussig Cancer Institute (CCTCI). Methods: Cases of MCL diagnosed at CCTCI were identified from our pathology database, yielding 85 unique pts. These subjects were retrospectively analyzed with approval of our Institutional Review Board. A total of 48 pts with advanced stage disease who underwent immediate treatment (within 90 days of diagnosis), and for whom adequate data for assignment of both MIPI and IPI existed, were the subject of review. Survival was identified from medical records and confirmed using a public social security database. Outcomes were compared using log-rank analysis of Kaplan-Meier survival analyses, and MIPI was calculated in accordance with the initial publication.1 Results: Pt characteristics at diagnosis were: median age 62 (range 39–85), 73% male, 75% ECOG performance status of 0-1, 96% stage IV disease, 52% elevated LDH, and 40% had extranodal involvement other than bone marrow (23% with GI involvement). Six pts had the blastoid variant of MCL. IPI scores at diagnosis were as follows: low (17%)/ low-intermediate (31%)/ high-int (25%)/ high (27%). MIPI scores at diagnosis were: low (33%) / int (25%)/ high(42%). Initial treatment included an anthracycline in 71% and rituximab in 60%. HyperCVAD was given 33%, and 23% underwent upfront (CR1/PR1) autologous transplantation. Median follow-up of survivors is 5.7 years. Median OS and RFS for all pts is 3.9 and 2.5 years, respectively. The IPI distinguished low and high-risk groups, but low-int and high-int groups were closely approximated (Figure 1). On the other hand, the MIPI distinguished 3 separate groups (Figure 2), including a high risk group with a 5-year survival of 11%. The MIPI maintained its prognostic capacity even in HyperCVAD-treated pts (log rank p=.01 for low/int/high MIPI among 16 pts, figure not shown.) The use of regimens including rituximab was not associated with improved OS (log rank p=0.21, comparing rituximab at any time vs none, figure not shown). Conclusions: Based on long-term follow-up of 48 pts diagnosed with MCL at CCTCI from 1998–2008, we verified the accuracy and ease of application of the MIPI for determining prognosis in MCL. On further analysis, rituximab did not impact OS of MCL pts. Clinical trials in MCL should employ the MIPI as a risk-stratification tool, and novel approaches are urgently needed for pts in the high-risk group. Disclosures: No relevant conflicts of interest to declare.

Abstract It is difficult to find figures for the expected rate of early mortality in diffuse large B-cell non-Hodgkin lymphoma (DLBCL) as many of the patients who are destined to die early do not enter clinical trials. Our own rate of early mortality (death within 100 days of the diagnostic test being performed) was higher than we had anticipated (23%). We undertook a study to look at risk factors for early mortality, and to see if there were any factors which could be improved by altering our investigation and initial management. Our haematology database has baseline demographic and prognostic information on all cases of haematological malignancy diagnosed in our centre. A two year period was chosen retrospectively from 1st January 2013 until 31st December 2014. This gave 97 registered patients with DLBCL. Early mortality was significantly related to the patient age, Eastern Cooperative Oncology Group (ECOG) performance status, lactase dehydrogenase value, presence of 2 or more sites of extranodal disease and the presence of B-symptoms. We did not see a significant relationship to the presence of marrow disease or the presence of disease bulk. As the majority of the relevant factors are already part of validated prognostic scoring systems, we evaluated the (International Prognostic Index) IPI, the R-IPI (revised International Prognostic Index) and the NCCN-IPI (enhanced International Prognostic Index) to see which was the best predictor of early mortality. The IPI gave the chance of 100 day mortality as 4% for low or low-intermediate risk patients, 16% for high-intermediate risk patients and 53% for high risk patients. The R-IPI gave the chance of 100 day mortality as 0% for low risk patients, 5% for intermediate risk patients and 48% for high risk patients. The NCCN-IPI gave the chance of 100 day mortality as 0% for low or low-intermediate risk patients, 13% for high-intermediate risk patients and 57% for high risk patients (figure 1). By six months, the mortality rate in high risk NCCN-IPI patients had reached 71% while the low and low-intermediate groups remained at 0%. Some patients were included who were not considered for potentially curative chemotherapy. Even with these patients excluded, the risk of 100 day mortality was still 50% in the high risk NCCN-IPI group. Some of the risk factors for mortality will likely worsen if the diagnosis or initial treatment are delayed. We therefore looked at the overall pathway from referral until first treatment. We found that those with early mortality tended to have a shorter time course until receiving their first treatment, likely reflecting the fact that they were more unwell when they first presented.
