Abstract Introduction:Central nervous system invasion in multiple myeloma (CNS-MM) is extremely rare (approximately 1% of MM). Prognosis of patients with CNS-MM is generally poor, and the median overall survival (OS) time from its diagnosis (Dx) has been reported to be 2 to 7 months. However, because of its rareness, most available data concerning CNS-MM are based on anecdotal reports on small case series. In this study, we retrospectively collected clinical data of Japanese patients with CNS-MM and analyzed them to reveal clinical features and prognosis of this disease entity. Methods:We conducted a nationwide multicenter retrospective study involving 107 centers that consist of educational facilities authorized by Japanese Society of Hematology and its related hospitals. CNS-MM was defined based on the previously reported criteria (Br J Haematol 2013;162:483-48). Univariate and multivariate analyses were performed to explore prognostic factors and the suitable treatment of CNS-MM. Results:From December 1978 to February 2016, 75 patients with CNS-MM were identified. The median age was 58 (range: 32-77 years). CNS invasion was detected at initial Dx of MM in 4% and at relapse in 96%. The median time from Dx of MM to that of the secondary CNS-MM was 1.8 years. Concomitant plasma cell leukemia (18%), skull plasmacytoma (12%), and myeloma cells in the cerebrospinal fluid (63%) were observed at the Dx of CNS-MM. Common symptoms of CNS-MM included consciousness disturbance (37%), cranial nerve palsy (25%), diplopia (18%), headache (16%), spinal nerve disorder (13%), and nausea/vomiting (12%). Intrathecal chemotherapy (IT) was used in 37%, cranial and/or spinal irradiation therapies (RTx) in 45% in addition to various systemic therapies, which included immunomodulatory drugs (IMiDs) (21%), bortezomib (19%), alkylators (21%), dexamethasone alone (6%), autologous stem cell transplant (auto-SCT, 4%), and allogeneic stem cell transplant (allo-SCT, 3%). With a median follow-up of 3.4 months from Dx of CNS-MM and of 31.5 months from that of MM, the median OS time from Dx of CNS-MM was only 3.7 months. The median OS times for the 12 untreated and 61 treated patients were 0.2 and 5.1 months, respectively (P < 0.01), suggesting that the patients who did not receive any treatments (Txs) were in a severe condition and their prognoses were extremely poor. In univariate analyses for the entire group, absence of both atypical lymphocytes and plasma cells in the peripheral blood at Dx of MM and no Tx for MM before Dx of CNS-MM were significantly favorable prognostic factors (P = 0.008 and P < 0.0001, respectively). Regarding Tx for CNS-MM patients who received any Txs (conventional chemotherapies, bortezomib, IMiDs, IT, and RTx), only RTx was correlated with longer OS time (P = 0.047). In multivariate analyses, RTx and IT had a significant impact on longer OS time (>6 months, OR = 3.80, 3.97, P = 0.002, 0.01, respectively). Although the prognosis of CNS-MM in this study cohort was very poor, seven patients could survive for >1 year from Dx of CNS-MM. Among them, RTx, IMiDs, IT, bortezomib, auto-SCT, and allo-SCT were given to 5, 4, 5, 3, 1, and 1 patients, respectively. Conclusions:Prognosis of CNS-MM is extremely poor in general. Although there must be a selection bias that patients who received various salvage Txs for CNS-MM were in a better condition, the results of our study suggest that multi-modality Txs with RTx, IT, and IMiDs/bortezomib may prolong the survival time in some cases. Prospective studies are needed to confirm our preliminary observations. Disclosures Takamatsu: Celgene: Honoraria; Janssen Pharmaceuticals: Honoraria.

Introduction :The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and subsequent coronavirus-19 (COVID-19) pandemic has impacted hematologic malignancies (HM) care worldwide. Reported risk factors for severe COVID-19 presentation include older age, medical comorbidities, and cardiac disease - many of which apply to patients with HM (Guan et al., 2020; Zhou et al., 2020). Additionally, patients with HM may be at even higher risk of infections with or complications from SARS-CoV-2 due to immune dysfunction from their underlying disease or treatment (He et al., 2020). However, data regarding rates of infection and outcomes in this population are limited. Here we describe the demographic characteristics, coexisting conditions, presenting symptoms, treatment, and outcomes of a cohort of patients with HM and COVID-19 infection at network sites across the Sidney Kimmel Cancer Center- Jefferson Health. Methods : We created an HM-specific COVID-19 database within our health system. Patients were identified for inclusion in the database by physician referral and query of the electronic medical record. Epidemiological, clinical, and laboratory data, therapy details, and outcomes on patients were obtained by accessing electronic medical records. A retrospective study of patients with a diagnosis of a HM- within 5 years of COVID-19 diagnosis-and a confirmed diagnosis of COVID-19 were was conducted using this database. A confirmed diagnosis of COVID-19 was defined as a positive result on a real-time RT-PCR assay of a specimen collected by nasopharyngeal swab. Results: More than 3,000 telehealth or in-person patient visits were conducted for patients with HM in the Jefferson Health Network between March 9, 2020 and July 15, 2020. During that period, 21 patients with HM had a confirmed diagnosis of COVID-19. Median age was 67 years (range 21-89). The majority of patients (86%) had at least 1 comorbid medical condition, and 76% had a history of tobacco use. The most common HM was multiple myeloma (7/21, 33%), followed by diffuse large B-cell lymphoma (3/21, 14%). 12/21 (52%) patients were on active cancer treatment at the time of COVID-19 diagnosis, and patients had received a median of 2 lines of cancer therapy (range 0-6). All 12 patients who were on active therapy at the time of COVID-19 diagnosis experienced a treatment interruption. Two patients had undergone prior autologous stem cell transplant (SCT) and 1 had undergone prior allogeneic SCT. Details on HM diagnosis and treatment are presented in Table 1. Twenty patients required hospital admission at the time of COVID-19 diagnosis, 7/21 were admitted to the ICU, and 6/21 required intubation. The most common presenting symptoms were fever (48%), cough (43%), and shortness of breath (43%), and lymphopenia (absolute lymphocyte count (ALC) &lt;1,000 B/L) was common at presentation (56%). More than half (13/21, 62%) of patients received some COVID-19 directed therapy, while 8 were treated with supportive care alone. As of July 15, 2020 18/21 (86%) patients were alive. Characteristics of the 3 patients who died are described in Table 2. Conclusion : In contrast to published reports, we found that the number of confirmed COVID-19 in patients with HM at our center was surprisingly low, with only 21 cases in 4 months. Furthermore, the mortality rate of 14% was lower than expected when compared to published cohorts of similar patients, which have shown mortality rates as high as 40% (He et al., 2020; Malard et al., 2020; Martín-Moro et al., 2020). Postulated reasons for the low number of infections include the early adoption of universal masking and robust utilization of telehealth to promote social distancing. In our small cohort, multiple myeloma was the most frequent HM diagnosis associated with COVID-19 infection, but this may be related to the prevalence of MM in our geographic area. The vast majority of HM patients with symptomatic COVID-19 were former smokers. Disclosures Binder: Janssen: Membership on an entity's Board of Directors or advisory committees; Sanofi: Consultancy.

The Impact

Abstract Background: In the current era, autologous stem cell transplant (ASCT) remains an effective form of treatment for patients diagnosed with multiple myeloma (MM), but it is not curative and a relapse is inevitable. A second, or salvage, ASCT provides better outcomes than conventional chemotherapy but it is infrequently used. Maintenance therapy after initial ASCT has been adopted as the standard in the US; however, there is limited data on the effects of maintenance therapy following salvage ASCT and the benefits are still unclear. Methods: We performed retrospective chart review of all patients with MM who received a second, salvage ASCT at time of first relapse at Washington University in St. Louis from 2008 to 2016. We identified two cohorts of patients, those who received maintenance therapy following salvage ASCT and those who did not. Patients who received maintenance therapy post-initial ASCT were excluded as the objective of this study was to determine the impact of maintenance post-salvage ASCT and maintenance post-initial ASCT may confound the results. Results: Sixty-five patients (who underwent second/salvage ASCT) were identified. Three were excluded from the analysis-two had treatment-related mortality following salvage ASCT and one received maintenance other than a proteasome inhibitor (PI) or an immunomodulatory drug (IMID). The maintenance cohort consisted of 31 patients, with 68% (n = 21) males and 32% (n = 10) females; the median age at salvage ASCT was 61 years (range 38-73). The no-maintenance cohort consisted of 31 patients as well with 45% (n = 14) males and 55% (n = 17) females. Their median age at salvage ASCT was 62 years (range 44-74). The characteristics of the two cohorts are summarized in Table 1. Most patients received PIs and/or IMIDs as part of their induction regimens prior to initial ASCT. All received melphalan conditioning. The response to treatment was similar between the two cohorts, with respective CR rates of 68% (n = 21) and 77% (n = 24) and median progression-free survival (PFS) of 46 months compared to 33 months. Following relapse, 16% (n = 5) of patients in the no-maintenance cohort proceeded directly to salvage ASCT without re-induction. All other patients received re-induction, mostly with PIs and/or IMIDs, with a median of 4 cycles for the maintenance cohort and 2 cycles for the no-maintenance cohort. For conditioning prior to salvage ASCT, 4 patients received Velcade-BEAM conditioning as part of a prospective trial at our site (NCT01653418); 3 from the maintenance cohort and 1 from the no-maintenance cohort. The rest received melphalan conditioning. Both cohorts had a CR rate of 52% (n = 16) post-salvage ASCT. Maintenance therapy after salvage ASCT consisted of lenalidomide (74%, n = 23), bortezomib (23%, n = 7), or pomalidomide (3%, n = 1). Three of the patients on bortezomib were originally started on lenalidomide but were switched due to intolerance. At time of data collection, the median follow-up was 49 months (range 9-105) for the maintenance cohort and 61 months (range 19-113) for the no-maintenance cohort. 45% (n = 14) of patients in the maintenance cohort and 90% (n = 28) of the no-maintenance cohort had relapsed. In the maintenance cohort, PFS following salvage ASCT was similar to what was observed following initial ASCT. The median estimated PFS post-salvage ASCT was 53 months (95% CI 42-64) compared to 46 months post initial ASCT (p = 0.144). Conversely, in the no-maintenance cohort PFS following salvage was only about 60% that of initial ASCT (21 months [95% CI 18-24]; compared to 33 months; p = 0.002). Conclusion: These results suggest that maintenance following salvage ASCT is associated with improved outcomes. Although patients who received maintenance post-initial ASCT were excluded, the benefits of maintenance post-salvage ASCT may extend to them as well. Ongoing prospective clinical trials will further clarify these benefits. Disclosures Schroeder: Amgen Inc.: Consultancy, Membership on an entity's Board of Directors or advisory committees.

Abstract Abstract 4082 Background: ARRY-520, a novel kinesin spindle protein (KSP) inhibitor, has been studied as a single agent and in combination with dexamethasone, and demonstrated promising clinical activity in patients with bortezomib- and lenalidomide-refractory multiple myeloma (MM). Carfilzomib, a novel irreversible proteasome inhibitor (PI), has also demonstrated single agent activity in relapsed and refractory MM, and recently received regulatory approval for this indication. Preclinical data support the presence of synergy with the combination of a PI and a KSP inhibitor via the latter's ability to down-regulate Mcl-1, supporting our hypothesis that the combination of carfilzomib and ARRY-520 (Car-ARRY) would be highly active in relapsed and/or refractory myeloma. We therefore aimed to combine these two agents for the first time, and here report the initial findings from the phase I dose-escalation in patients with relapsed and/or refractory MM. Methods: The primary objective was to determine the maximum tolerated dose (MTD) and the safety/tolerability of the Car-ARRY combination. Secondary objectives were to determine efficacy as measured by the overall response rate, time to progression, progression free survival and time to next therapy. Patients had to have myeloma that was relapsed and/or refractory, be ineligible for autologous stem cell transplant, bortezomib refractory/intolerant, and prior lenalidomide exposure. ARRY-520 was administered intravenously over 1 hour on days 1, 2, 15 and 16, while carfilzomib was administered intravenously over 30 minutes on days 1, 2, 8, 9, 15 and 16 on a 28 day cycle. All patients received growth factor support with filgrastim. Dose-escalation used a standard 3+3 schema proceeded based on dose-limiting toxicities (DLTs) during cycle 1, with planned escalation of the dose of ARRY-520. Dose level 1 was ARRY-520 0.75 mg/m2, and carfilzomib was dosed at 20 mg/m2 for cycle 1 on days 1 and 2 and all subsequent dose were at 27 mg/m2. Adverse events (AEs) were graded by NCI-CTCAE v4, while responses were assessed by the modified International Uniform Response Criteria. Results: To date, 8 patients have been enrolled in the ongoing dose escalation phase. The median age was 66 (range 47–80), 6/8 were males, and the median number of prior therapies was 4 (range 2–10). 7/8 patients had undergone prior autologous stem cell transplant, and all patients were bortezomib refractory or intolerant. In the first cohort, 3 patients were enrolled and no dole limiting toxicity (DLT) was observed. During the second cohort, ARRY-520 was escalated to 1 mg/m2 with carfilzomib at 20/27 mg/m2, and among the first 3 patients, one patient suffered a DLT in the form of an admission for influenza pneumonia with non-neutropenic fever. Expansion of cohort 2 is currently underway. Among the 6 patients who completed the first cycle of therapy, 5 remain on study. In the first cohort, one patient remains on study with 6 cycles and achieved a near complete remission, 1 patient achieved stable disease, and 1 patient suffered disease progression after first cycle. In the second cohort, all three patients who completed the first cycle have stable disease and remain on trial. In the first 6 toxicity-evaluable patients who have completed one cycle, grade (G) 3 events included one each of pneumonia, diarrhea, and hyperglycemia. There was limited hematologic toxicity with 4/6 patients with G1/2 thrombocytopenia, 3/6 patients with G1/2 anemia, and 1/6 patient with G1/2 neutropenia. Additional G1/2 non-hematologic toxicity included 3/6 patients with diarrhea, 3/6 patients with dyspnea, 3/6 patients with transient elevations in creatinine and 3/6 patients with aspartate aminotransferase elevations. An MTD has not been established and enrollment is ongoing in cohort 2 with carfilzomib at 20/27mg/m2 and ARRY-520 at 1.0 mg/m2. Conclusions: The combination of ARRY-520 and carfilzomib is well tolerated with limited hematologic toxicity and a manageable side effect profile. Notably, in this patient population, with patients who have bortezomib refractory/intolerant myeloma, the combination has demonstrated early signals of activity. Updated safety and efficacy data for all patients will be presented at the meeting.

Abstract Introduction The prognosis of patients with multiple myeloma (MM) has improved in the last years due to the important advances in the knowledge of the biology of the disease, the implementation of new drugs and the incorporation of autologous hematopoietic stem cell transplant (autoHSCT). The allogenic hematopoietic stem cell transplant (alloHSCT) continues to be controversial: it offers a curative potential but with the cost of high toxicity, limiting the procedure to those young patients with a high-risk disease. This procedure shall be performed in expert centers and, whenever possible, in the context of a clinical trial. In the following we describe the experience of our center with alloHSCT in advance multiple myeloma patients. Patients and methods A total of 18 patients were diagnosed with multiple myeloma received an alloHSCT during a 13 year period (1996-2013), with a median age of 46 ± 5.9 years. All of our patients received an allogenic HLA matched sibling donor with reduced-intensity conditioning. The majority of patients were transplanted because of advanced disease, relapse after an autologous transplant or as part of a sequential transplant in patient with a high risk disease. One patient received, in two occasions, an alloHSCT. Around 70% of patients had received more than 3 previous lines of treatment including, in nearly 95%, an autoHSCT. Patient's characteristics can be found on table 1, characteristics of the procedure can be found in table 2.Table 1.Patient«s CharacteristicsN (%)GenderMale Female10 (55,5%) 9 (44,4%)Secreted ProteinIgGκ IgG λ IgA κ BJ Plasmocitoma8 (44,4%) 4 (22,2%) 2 (11,1%) 3 (16,7%) 1 (5,6%)Debut DS stageII-A II-B III-A III-B Plasmocitoma5 (27,8%) 1 (5,6%) 8 (44,4%) 3 (16,7%) 1 (5,6%)Cytogentics at diagnosisMissing Unfavorable Favorable10 (55,5%) 6 (33,3%) 2 (11,1%)Previous lines of treatment²2 3-4 ³56 (33,3%) 10 (55,5%) 2 (11,1%)Previous autoHSCTYes No17 (94,5%) 1 (5,6%)Previous radiotherapyYes No8 (44,4%) 10 (55,6%)Disease status at transplantComplete remission Partial remission Relapse9 (50,0%) 3 (16,7%) 6 (33,3%)Table 2.Treatment characteristicsN (%)Conditioning regimenMyeloablative Reduced-intensity6 (33,3%) 12 (66.7%)Stem cell sourceBone marrow Peripheral blood4 (22.2%) 14 (77.8%)GVHD prophylaxisCsA+MTXCsA+CSCsA+MMF10 (55.6%) 3 (16.7%) 5 (27.8%)InfectionsYes No16 (88.9%) 2 (11.1%)MucositisYes No12 (66.7%) 6 (33.3%)Acute GVHDYes II-IV III-IV No4 (22.3%) 3 (16.7%) 1 (5.6%) 14 (77.8%)Chronic GVHDNo Limited Extensive8 (44.3%) 5 (27.8%) 5 (27.8%) Results: Transplant related mortality (TRM) before day 100th was one case due to a thromboembolic event. Global TRM was 16.6% (3 cases). The incidence of acute graft versus host disease (aGVHD) was 22%, controlled on most cases when corticosteroids were initiated. More than half of the patients developed chronic graft versus host disease (cGVHD), with an equal distribution on either presentation as limited or extensive. (Table 2) The total number of patients eligible for analysis was 17 (one patient was lost on follow-up). With a median follow up of 11 years, the overall survival (OS) was of 8.06 years [IC 95% 4,33-11,78] (figure 1.) and the estimated progression free survival (PFS) was of 25.83 months [IC 95% 8.87-42.79](figure 2). A total of 5 (29,4%) patients are still alive and 2 (11,7%) of them are in complete remission, of these 1 patient did not have a previous autoHSCT with a follow up of almost 15 years. Conclusions: Our results are similar to those reflected on the literature1-2. However we have to point out that our population is homogenous with advanced MM with more than 3 previous lines of treatment including in most cases auto-HSCT. In spite of this, morbility and mortality in our cohort was acceptable with the limitation of a high rate of cGVHD. There is a need of more studies including more patients to evaluate the role of alloHSCT in the era of new drugs for MM. References 1. Rosi-ol L et al.

Abstract Introduction: Acute myeloid leukemia (AML) is heterogenous disease with a range of cytogenetic and molecular changes. Several molecular mutations identified in AML patients at diagnosis have prognostic implications and play important roles in guiding induction and consolidative treatment decisions. The prognostic impact of mutations peri allogeneic stem cell transplant are less well characterized. In this study, we examine the significance of pre and by D100 Post-transplant mutation status in AML patients underwent Fludarabine/Melphalan conditioned reduced intensity allogeneic stem cell transplant (SCT). Methods: AML patients who are in morphologic complete remission (CR1 or greater) with available molecular mutation at diagnosis, within 6 weeks prior to allogeneic SCT, and by 100 days post-transplant were included. Variables analyzed included baseline demographics, clinical variables (CIBMTR disease risk index (DRI), type of transplant, ELN risk, performance status) and 23 recurring molecular mutations. Analysis was also performed by grouping mutations into six pre-defined gene groups based on gene function (Table 2). Multivariable cox regression analysis was adjusted for age, gender, DRI and molecular mutation. Backward selection method was used to select the best combination of genes that is associated with overall survival (OS) and relapse-free survival (RFS). Results : A total of 142 AML patients with molecular genetic data available from 2014 to June, 2020 at Weill Cornell Medicine/New York Presbyterian Hospital were analyzed. Clinical characteristics of the patients are summarized in Table 1. The median age was 58 years (range 20 -78). Total of 261 mutations were detectable at diagnosis (Table 3). Prior to allo SCT and by D100, the detectable mutations were 87 and 40 respectively, which represent 56 and 26 patients. High-dose chemotherapy was less effective on clearing DNMT3A, ASXL1, TET2 (DAT) or IDH mutations, resulting in over-representation of DAT and IDH mutations prior to transplant. With a median follow-up time of 25 months, the median overall survival for the group was 40.8 months. The presence of mutations in TP53 at diagnosis was associated with worse OS by both univariate (HR 3.67, p=0.0030, CI 1.56-8.68) and multivariate analysis (HR 4.75, p=0.0014, CI 1.82-12.39) with median OS reduced from 49.3 to 19.3 months (p=0.002). High CIBMTR DRI (HR 0.17, p=0.0018, CI 0.05-0.51) predicted reduced OS and RFS, and Age &gt;60 at diagnosis was associated with worse OS (HR 1.7 CI 1.04-3, p 0.03). Presence of any molecular mutation prior to transplant did not impact OS or RFS. For patients with any persistent mutations by D100 post-transplant, both OS ( HR 2.04, p 0.027, CI 1.08-3.8) and RFS (HR 1.99, p 0.025, CI 1.09-3.6,) were reduced in the univariate analysis, but not on multivariate analysis (HR 1.88, p 0.5, CI 0.99-3.49). Analysis based on six mutational groups (table 2) did not show any difference in their OS or RFS. However, worse RFS was independently associated with persistent IDH1 (HR 3.8, p 0.004, CI 1.07-56,), TET2 (HR 3.9, P 0.04, CI 1.04-14.1), and FLT3-ITD (HR 4.5, p 0.01, CI 1.7-52). Worse OS was independently associated with persistent TET2 (HR 3.9, p 0.013, CI 1.04-14.1), with a trend towards worse OS for IDH1, FLT3-ITD, with a trend towards worsening OS and RFS for ASXL1 (OS HR 7.4, p 0.06, CI 0.86 -63; RFS HR 4.9, p 0.06, CI 0.9-26) and DNMT3A (OS HR 2.3, p 0.12, CI 0.86-6.9; RFS 2.9, p 0.08, CI 0.98-8). Association with worse clinical outcomes remained significant after multivariate analysis for TET2 (both OS HR 3.98 p 0.041, CI1.07- 32 and RFS HR 5.8, p 0.032, CI 1.1- 29), IDH1 (RFS HR 8.02, p 0.049, CI 1.02 - 65) and FLT3-ITD (RFS HR 11.4, p0.010, CI 2.2- 80). Conclusions: Presence of TP53 mutations was associated with worse OS. Presence of pre-transplant mutation did not impact RFS or OS. Persistent presence of mutations in TET2, IDH1 and FLT3-ITD after Fludarabine/melphalan conditioning regimen allogeneic SCT were associated with shorter RFS and OS (in the case of TET2) independent of CIBMTR DRI. This analysis supports association of adverse outcomes in AML patients with selected persistent mutations by D100 post-transplant in reduced intensity transplant setting. Post-transplant strategies that can further eliminate persistent mutations should be investigated in prospective studies. Figure 1 Figure 1.

Introduction: Patients (pts) with high-risk multiple myeloma (HRMM) experience early disease progression post autologous stem cell transplant (ASCT). The median progression free survival (PFS) for HRMM pts undergoing ASCT with lenalidomide (len) maintenance ranges between 27 and 42 months in high risk pts and 22 months in ultra-high risk, defined by two or more adverse cytogenetic abnormalities such as: gain(1q), t(4;14), t(14;16),t(14;20), or del(17p)( Chakraborty et al, Leukemia,2018 and Jackson et al, Lancet, 2018). Elotuzumab, a humanized IgG kappa monoclonal antibody against SLAM-F7 (CS-1), is approved in combination with len and dexamethasone (ERd) in pts with relapsed MM (Dimopoulus et al, BJH, 2017). It directly activates natural killer (NK) cells and mediates myeloma cell death by antibody-dependent cell mediated cytoxicity. We hypothesized that administration of ERd as post-ASCT consolidation will enhance an immune-competent phenotype, by restoring NK cells and effector T-cell populations at a time of maximal disease de-bulking, and will ultimately improve outcomes among pts with HRMM. Methods: Thirty-one HRMM patients who achieved stable disease or better were treated beginning at 30-90 days post ASCT with ERd (29/31 pts) or elotuzumab/pomalidomide )/dex (EPd) (2/31 pts) between September 2016 and February 2019. With institutional review board approval, electronic medical records were reviewed for baseline characteristics, treatment history, adverse events (AE) while on therapy as defined by common terminology criteria for adverse events (CTCAE), and survival outcomes. Treatment with ERd or EPd was administered for 4 consecutive 28-day cycles per standard dosing regimens with a tapering or discontinuation of corticosteroids per investigator discretion with cycles 3 and 4. HRMM was defined by any of the following: ISS or Revised-ISS stage 3, CD-138 selected FISH with del 17p, 1q21 gain, t(4;14), t(14;16), and t(14;20), cytogenetics with 13q del or complex karyotype, and/or high-risk gene expression profile score. Ultra-HR pts were defined by having both del 13q and 1q21 gain by FISH based on recent unpublished COMPASS data. Minimal residual disease (MRD) was evaluated upon achievement of very good partial remission or complete remission using 10-color multiparametric flow cytometry. PFS was measured using the log-rank test. Response criteria was defined per International Myeloma Working Group criteria. Results: Baseline characteristics of all 31 patients are shown in Table 1. Thirty-four percent were ISS-3, 71% (22/31 pts) had high-risk FISH, of which 19% were ultra-high risk (6/22 pts). Seven pts (22.6%) underwent tandem-ASCT pre-consolidation. Of the 8 pts who had GEP testing, 2 (25%) were high risk. Best response to treatment by cycle is depicted in Table 2. Consolidative ERd/EPd deepened response compared to post-ASCT with 71.4% vs 19.4% achieving stringent complete remission (sCR). Post-consolidation, 19.3% vs 12.9%, pre-consolidation, achieved MRD negativity. With a median follow-up of 24.8 months, median PFS was 31.4 months (Figure 1). There was no significant association between median PFS and variables such as tandem ASCT and ultra-HR using multivariate cox regression. Although all pts experienced at least one AE while on therapy, only 1 patient (3.22%) experienced a grade 3 AE. Hematologic AEs included: anemia (48%), neutropenia (45%), and thrombocytopenia (52%), while the most common non-hematologic AEs included: fatigue (32%), malaise (23%), and back pain (19%). One patient experienced a serious AE (SAE) which was PCP pneumonia requiring hospitalization, resulting in early discontinuation from therapy. There was no treatment-related mortality. Conclusion: ERd or EPd as 4 months of fixed duration consolidation therapy post-ASCT resulted in a median PFS of 31.4 months amongst pts with HRMM, similar to or perhaps surpassing historical reports of HRMM pts receiving lenalidomide maintenance until progression. This therapy may offer comparable, if not superior, outcomes while having the advantage of allowing for significant time without therapy and perhaps improving quality of life and financial toxicity. This study is limited due to its retrospective nature. Larger prospective studies evaluating fixed duration ERd/EPd in HRMM patients post ASCT should be conducted.

Abstract Background The role of lenalidomide for maintenance after myeloblative therapy and autologous stem cell transplant (ASCT) has been established based on the CALBG 100104 and IFM 2005-02 experience. Continuous low dose lenalidomide demonstrated a significant benefit in progression free survival (PFS), time to progression (TTP) in both trials and the CALBG trial also demonstrated a benefit in early overall survival. The benefit in PFS with lenalidomide is preserved in patients with high risk cytogenetics and in complete remission after ASCT. Proteaseome inhibitors (PI) have been studied after ASCT in a hybrid consolidation/maintenance model with a predefined course of bortezomib-based therapy, which was well tolerated and led to a significant improvement in response rates and in PFS. However long term proteasome inhibitor maintenance therapy has been limited by the route of administration. The combination of PIs and immunomodulatory agents (IMiDs) have a strong preclinical rationale, and their activity has been confirmed with high response rates in various combinations in both newly diagnosed and relapsed/refractory myeloma. MLN9708, an oral PI, may be more convenient as an oral therapy to be studied in the maintenance setting. Here we report preliminary data from a pilot study of the combination of MLN9708 and lenalidomide as maintenance therapy post ASCT. Methods This is a single arm phase II study with the primary objective to establish the safety and efficacy (PFS) of MLN 9708 (Ixazomib) and lenalidomide in the maintenance setting post ASCT. The secondary objectives were to evaluate the incidence of secondary primary malignancy, the best response rate (sCR/nCR/VGPR/PR), time to progression and time to next therapy. Patients must have undergone ASCT with melphalan as a preparative regimen within 12 months of initiation of induction for newly diagnosed myeloma. Patients started maintenance therapy 60-180 days post ASCT. Treatment consisted of 28 day cycles of oral MLN9708 4 mg on days 1, 8, 15, and oral lenalidomide 10 mg daily on days 1-28 with a dose increase to 15 mg after 3 months if tolerating well. Adverse events (AEs) were graded by NCI-CTCAE v4. Response was assessed by the modified International Uniform Response Criteria. Results A total of 16 patients have been enrolled with a median age of 60 years (range 51-74); 12/16 patients were male. 6 patients had ISS stage 1, 2 patients had stage II, 5 patients had stage III, and 3 had an unknown stage. 14 of the patients remain on trial, 2 patients have discontinued maintenance therapy. 1 patient with high risk disease, including del17p, del 13 discontinued due to rapidly progressive disease during cycle 2; 1 patient discontineud due to hospitalization for bilateral pneumonia. 3 patients had a treatment related SAE including 2 patients with PNA, 1 pt with G2 dehydration requiring hospitalization. 5 patients required a dose reduction in MLN9708 or lenalidomide due to G3/4 thrombocytopenia (n=2); dose delays for thrombocytopenia/neutropenia (n=3); one patient also had concurrent grade 3 rash. Hematologic toxicity included 3/16 patients with G3/4 thrombocytopenia, 9/16 with G1/2 thrombocytopenia, 5/16 patients with G3 neutropenia and 6/16 patients with G1/2 neutropenia. G3/4 drug-related non-hematologic AEs occurring in >1/16 of patients were limited to 2 patients with G3 creatinine elevation (in the setting of hospitalization for pneumonia). Additional non-hematologic G1/2 events included 9/16 patients with nausea, 5/16 with diarrhea, 9/16 with constipation, 4/16 with emesis, 6/16 patients with G1 rash; 1 pt with worsening of baseline G1 neuropathy. Conclusions The combination of MLN9708 and lenalidomide as maintenance therapy post ASCT for NDMM is a well-tolerated combination. 14/16 patients remain on study with only 1 patient discontinuing due to toxicity (pneumonia). The preliminary experience demonstrates the combination is safe, feasible and well tolerated with minimal toxicity and no unexpected toxicity.

Abstract Introduction Multiple Myeloma (MM) is a heterogeneous disease with highly variable survival. Gene expression profiling (GEP) classifiers, such as the EMC-92, can consistently distinguish high risk patients from standard risk patients. Other prognostic factors for MM include the international staging system (ISS) and FISH. Here we present a comparison of prognostic factors and introduce a novel stratification based on EMC-92 and ISS. Methods Scores were calculated for the GEP classifiers EMC-92, UAMS-70, UAMS-17, UAMS-80 and MRC-IX-6 for the following five studies: HOVON-65/GMMG-HD4 (n=328; GSE19784), MRC-IX (n=247; GSE15695), UAMS-TT2 (n=345; GSE2658), UAMS-TT3 (n=238; E-TABM-1138 and GSE2658) and APEX (n=264; GSE9782; for details, see Kuiper R, et al. Leukemia (2012) 26: 2406–2413). FISH data were available for the HOVON-65/GMMG-HD4 trial and the MRC-IX trial. ISS values were available for all datasets except UAMS-TT2. Univariate associations between markers and overall survival (OS) were investigated in a Cox regression analysis, using Bonferroni multiple testing correction. For pair wise analysis of markers, the significance in the increase of partial likelihood was calculated. In order to find the strongest combination (defined as the highest partial likelihood) of GEP-ISS, we compared these pair-wise on the same data. Training sets of classifiers were excluded for those analyses in which that specific classifier was tested. All survival models have been stratified for study. The calculations were done in R using the package survival. Results Prognostic value of FISH, GEP and serum markers was determined in relation to overall survival (Figure 1). GEP classifiers generally performed much better than FISH markers. Of 6 FISH markers with known adverse risk, del(17p), t(4;14), t(14;20) and del(13q) demonstrated a significant association only in one of two data sets with available FISH (HOVON-65/GMMG-HD4). GEP classifiers, on the other hand, are much more robust. Classifiers EMC-92, UAMS-70 and UAMS-80 significantly identify a high-risk population in all evaluated data sets, whereas the UAMS-17 and the MRC-IX-6 classifiers predict high-risk patients in three of four datasets. As expected, ISS staging demonstrated stable and significant hazard ratios in most studies (three out of four). Indeed, when evaluating a merged data set, both ISS and all evaluated GEP classifiers are strong prognostic factors independent of each other. Markers with additive value to each other include all combinations of GEP classifiers as well as the combination of GEP classifiers together with ISS. Tested in independent sets, the EMC-92 classifier combined with ISS is the best combination, as compared to other classifier-ISS combinations tested on the same independent data sets. The strongest risk stratification in 3 groups was achieved by splitting the EMC-92 standard risk patients into low risk, based on ISS stage I, and intermediate risk, based on ISS stage II and III. This stratification retains the original EMC-92 high-risk group, and is robust in all cohorts. The proportions of patients defined as low, intermediate and high risk for this combined EMC-92-ISS classifier are 31% / 47% / 22 % (HOVON-65/GMMG-HD4), 19% / 61% / 20 % (MRC-IX), 46% / 39% / 15 % (UAMS-TT3) and 32% / 55% / 13 % (APEX). Variability in low risk proportion is caused by the variable incidence of ISS stage I. Conclusions We conclude that GEP is the strongest predictor for survival in multiple myeloma and far more robust than FISH. Adding ISS to EMC-92 results in the strongest combination of any of the GEP classifier-ISS combinations. Stratification in low risk, intermediate and high risk may result in improved treatment and ultimately in longer survival of MM patients.

Abstract Background: Venetoclax (VEN) is a potent, selective, orally available small-molecule BCL-2 inhibitor that induces cell death in multiple myeloma (MM) cell lines and primary samples, particularly those with t(11;14), which mostly have a favorable high BCL-2, low BCL-XL, and low MCL-1 profile. Methods: In this Phase 1, open-label study, patients (pts) with relapsed/refractory (R/R) MM received VEN monotherapy. Objectives of the study were to assess safety, pharmacokinetics, maximum tolerated dose, recommended phase 2 dose, and efficacy (objective response rate [ORR], time to progression [TTP], and duration of response [DoR]) of VEN. After a 2-week lead in period with weekly dose escalation, VEN was given daily at final doses of 300, 600, 900, or 1200mg in dose escalation cohorts and 1200mg in the safety expansion. Pts who progressed during VEN monotherapy could receive VEN plus dexamethasone and continue in the study. Results: As of 01July2016, 66 pts were enrolled in the study (30 in dose escalation cohorts and 36 in safety expansion). Median age was 63 years and 39 (62%) pts were ISS stage II/III. The median number of prior therapies was 5 (range: 1-15), and 62 (94%) pts had received bortezomib (46 [70%] refractory), 62 (94%) received lenalidomide (51 [77%] refractory), and 50 (76%) had prior autologous stem cell transplant. Thirty (46%) pts had t(11;14) MM. Median time on VEN monotherapy for all pts was 2.5 months (.2-23); 17 (26%) elected to receive VEN and dexamethasone combination after disease progression for a median of 1.4 months (.1-11). Fifty-one (77%) pts discontinued the study for the following primary reasons: 39 related to disease progression, 5 due to AEs/toxicity, 2 withdrew consent, 1 was lost to follow up, and 4 for other reasons not specified. Common adverse events (AEs) in ≥20% of pts were nausea (48%), diarrhea (36%), neutropenia (32%), thrombocytopenia (32%), fatigue (27%), anemia (23%), back pain (21%), and vomiting (21%). Grade 3/4 AEs in ≥10% of pts were thrombocytopenia (26%), neutropenia (20%), lymphopenia (15%), anemia (14%), and decreased white blood cells (12%). Serious AEs in ≥2 pts were pneumonia (n=5), sepsis (3), pain, pyrexia, cough, and hypotension (2 each). Two pts experienced dose-limiting toxicities at 600mg of abdominal pain and nausea. Eight deaths were reported: 6 due to disease progression, 1 due to lung disorder, and 1 due to brain hemorrhage following injury; neither were considered by the investigator as related to VEN. Steady state VEN exposures were approximately dose proportional at all doses but 900mg. As of 20July2016, ORR for all pts on VEN monotherapy was 21% (14/66) and 10 (15%) achieved very good partial response (VGPR) or better (2 stringent complete response [sCR], 2 CR, 6 VGPR) (Figure); median DoR and TTP was 9.7 and 2.6 months, respectively. Most objective responses (12/14 [86%]) were reported in the subset of pts with t(11;14) MM. In this group, ORR was 40% (12/30) and 27% (8/30) achieved a response of ≥VGPR; median DoR for pts with t(11;14) was 9.7 months (95% CI: 6.3, -). Pts who achieved at least minimal response in the t(11;14) group (14/30) had a median of 4 prior therapies and were mostly refractory to bortezomib, lenalidomide, or double refractory (71% [10/14] each). For two pts with response in the non-t(11;14)/undetermined group, 1 had a translocation of chromosome 14 with an unidentified partner, and the other had no cytogenetics data available. DoR was 9.5 and 7.2 months in these pts and both are still ongoing. Median TTP for pts with or without/undetermined t(11;14) was 6.6 and 1.9 months, respectively. The median best percent change in primary M protein for pts with t(11;14) (n=23) was -53% vs +11% in the non-t(11;14)/undetermined group (n=23). Additional biomarker subgroup analyses (n=32) showed that efficacy was primarily observed in pts with myeloma cells expressing a favorable BCL-2 family expression profile (high BCL-2, low BCL-XL, low MCL-1) by immunohistochemistry, which was significantly enriched in the t(11;14) population. Indeed, although high BCL-2 expression was observed in a majority of bone marrow core biopsy samples (88%), the t(11;14) subgroup was enriched (81% vs 25%) for tumors expressing high BCL-2, low BCL-XL, and low MCL-1. Conclusions: VEN monotherapy has an acceptable safety profile and clear anti-myeloma activity in pts with R/R MM, primarily with t(11;14) having a high BCL-2, low BCL-XL and low MCL-1 expression levels.

Abstract Background: High dose chemotherapy followed by autologous stem cell transplant (ASCT) is the standard curative option for patients with relapsed or refractory, chemosensitive, aggressive non-Hodgkin lymphoma (NHL). The optimal timing for ASCT following salvage chemotherapy is not known. Cancer Care Ontario (CCO)-the cancer agency for Ontario, Canada's largest province-treatment guidelines recommend that no more than 91 days should elapse from the first day of salvage chemotherapy to stem cell transplant. We evaluated the impact of time to stem cell transplant in the context of the international CCTG LY.12 phase 3 clinical trial. Methods: Patients with relapsed or refractory (R/R) aggressive NHL were randomly assigned to gemcitabine, cisplatin and dexamethasone (GDP) or dexamethasone, cytarabine, cisplatin (DHAP), with or without rituximab, followed by ASCT [Crump JCO 2014]. Time interval definitions were based on CCO guidelines: Total Wait Time (TWT) as the number of days from the first day of salvage chemotherapy to day of ASCT; Apheresis Wait Time (AWT) as the number of days from the first day of salvage to the first day of stem cell collection; Stem cell transplant Wait Time (SWT) as the number of days from the last day of stem cell collection to the day of ASCT. Patients were considered to have experienced a delay in TWT, AWT or SWT if the time intervals exceeded 91, 70 and 21 days respectively. Overall survival (OS) and event-free survival (EFS) from transplant date were compared between patients who met and exceeded TWT targets using a Cox proportional hazards model. A linear regression model was applied to analyze TWT as a continuous variable. Univariate and multivariate analyses were performed to estimate the adjusted hazard ratio (HR) for TWT for the following co-variables: age ≤60, performance status 0/1, disease stage (I/II), presence of ≤1 extranodal sites, and response after cycle 2 (complete response, CR; complete response, unconfirmed, CRu; partial response, PR). Results: Of 619 patients enrolled on LY.12, 307 (47%) had sufficient response to salvage chemotherapy and adequate stem cell collection to complete ASCT on protocol. Among these, median age was 54.6 years, 64% were male and 94% had a performance status of 0 or 1. International Prognostic Index (IPI) score at relapse was 0-1 in 45%, 2 in 31% and ≥3 in 24%. The majority of patients had poor risk disease at study entry; 58% had a best response of stable disease (SD) or progressive disease (PD) to primary therapy, or initial duration of response < 1 year. Following up to 2 cycles of salvage chemotherapy, 75/307 (24%) achieved CR/CRu, 142/307 (46%) achieved PR, 89/307 (29%) had SD. One patient had missing data. The median TWT for the total transplanted population was 91 days (range 50-217). Median AWT and SWT were 63 (range 0-151) and 26 (range 6-146) days, respectively. Fifty percent of patients exceeded TWT target of 91 days; 32% and 57% of patients exceeded AWT and SWT targets. There was no difference in median OS (HR 0.96, 95% CI 0.66-1.39, p=0.81) or EFS (HR 1.13, 95% CI 0.82-1.55, p=0.46) between patients who exceeded and met TWT targets. The 4-year OS for patients who met and exceeded TWT was 62% and 64%, respectively. The 4-year EFS for patients who met and exceeded TWT was 43% and 50%, respectively. When analyzed as a continuous variable, TWT did not affect OS (HR 0.99) or EFS (HR 0.99). Comparison of the quartiles with shortest and longest TWT demonstrated HR 0.72 (95% CI 0.42-1.26, p=0.25) for overall survival and 0.69 (95% CI 0.44-1.09, p=0.11) for EFS. Comparison of the 10th and 90th percentiles for TWT demonstrated HR 0.67 (95% CI 0.28-1.59, p=0.36) for overall survival and 0.71 (95% CI 0.35-1.44, p=0.34) for EFS. Only the presence of ≤1 extranodal sites of disease was found to be predictive of OS in the transplanted population on univariate and multivariate analysis (adjusted HR 0.51, p=0.005). The median TWT was longer for the 31 patients transplanted at Italian centers, compared to 266 transplanted at Canadian centers (median TWT 90 vs. 118 days, t < 0.0001). Conclusion: In this exploratory analysis, limited to patients who completed transplant on the LY.12 clinical trial, we did not find evidence that those meeting current CCO ASCT wait time targets had superior outcomes compared with those who did not.
