Abstract Background: High-dose melphalan followed by autologous hematopoietic cell transplantation (HCT) remains the integral component of multiple myeloma (MM) therapy in the era of novel agents. We published our prior study with the use of high-dose melphalan + bortezomib (Mel/Vel) conditioning regimen for tandem transplants in refractory MM patients (Nishihori, et al. Br J Haematol 2012). We designed a phase 2 trial using MelVel conditioning followed by autologous HCT in patients with newly diagnosed chemosensitive MM (NCT 00948922). Methods: Sixty seven newly diagnosed MM patients who achieved ≥ partial response (PR) to induction therapy with ≤grade 1 peripheral neuropathy (PN) were enrolled from 12/2009 to 06/2014. Patients received high-dose melphalan at 100 mg/m2 IV for 2 days, immediately followed by 1 dose of bortezomib at 1.3 mg/m2 (Mel/Vel conditioning). Maintenance therapy was not prescribed by design. The protocol later was modified to include maintenance bortezomib subcutaneously (started at 3 months after HCT) at 1.3 mg/m2 weekly x4, every 8 weeks, for a total of 6 cycles. Progression-free and overall survival (PFS and OS) estimates were calculated using Kaplan-Meier method. Results: A total of 67 patients received autologous HCT. The median age was 58 (25 - 73) years with the following disease characteristics: Durie-Salmon stage, 3A (72%) and 3B (10%); IgG (55%), IgA (21%), IgD (1%), and light chain (22%). High-risk cytogenetics/FISH were seen in 28% of patients. The median beta-2 microglobulin was 3.3 (range, 1.3 – 34.8). Induction regimens were bortezomib-based in 39%, lenalidomide-based in 19% and, both bortezomib and lenalidomide in 42%. Median time from initiation of induction to HCT was 204 days (range, 101 - 664). Responses prior to HCT were stringent CR (sCR) 21%, CR 12%, very good partial response (VGPR) 34%, and PR 33%. Neutrophil engraftment was achieved after a median of 11 days (range, 10 – 14) and platelet engraftment occurred after a median of 15 days (range, 11 – 22). Median CD34 cell dose was 3.8 x 106/kg (range, 2 – 20.08). Responses at 3 months after HCT (in 64 evaluable patients) were sCR 47%, CR 14%, VGPR 20%, PR 16% and progressive disease 3%. Bortezomib maintenance was prescribed to 31 patients (46%). Prevalence of grade 1 PN before (n=67) and at 3 months (n=64) after HCT were 37% and 38%, respectively. Two patients withdrew consent to initiate maintenance and 1 patient was unable to initiate maintenance due to grade 1 PN (baseline PN of 0). At the time of review, a median number of maintenance delivered was 4 (range, 1-6) and only one patient required dose reduction. The 2-year PFS and OS estimates are 62% (95% CI 0.47 – 0.75) and 90% (95% CI 0.80 – 0.97) with a median follow-up of 21 months (range, 2 – 54). The 1-year PFS estimates were 85% (95% CI 0.65 – 0.97) for bortezomib maintenance vs. 81% (95% CI 0.66 – 0.92) for no maintenance (p=0.6). There were no significant differences in PFS or OS stratified by cytogenetic/FISH risk status. There was no transplant related mortality. Conclusions: The combination of bortezomib and high-dose melphalan (Mel/Vel) as conditioning regimen for autologous HCT is well tolerated and appears to improve responses after HCT. Weekly x4 post HCT bortezomib maintenance given every 8 weeks appears to be well tolerated and is a promising strategy for eligible patients. Longer follow up is required to assess the benefit of post HCT maintenance strategy. Disclosures Baz: Millennium: Research Funding. Alsina:Millennium: Consultancy, Research Funding.

Abstract Background High dose melphalan (MEL) preceding autologous hematopoietic cell transplantation (HCT) for MM continues to be the standard of care. No regimen has been clearly proven superior to MEL 200 mg/m2 (MEL 200). The combination of Busulfan (Bu) and MEL was shown to improve progression free survival (PFS) (Lahuerta, et al; Haematologica. 2010 Nov; 95 (11):1913-20). The combination of bortezomib (Vel) with MEL also demonstrated superior PFS vs. MEL alone using historical controls (Roussel et al; Blood. 2010; 115:32-7). We studied a conditioning regimen combining Bu, MEL and Vel (BuMelVel) in an open label phase II study aimed at improving PFS after HCT for MM. To assess the potential value of this novel regimen, we performed a comparative analysis between BuMelVel and a cohort of patients conditioned with MEL 200 from the Center for International Blood and Marrow Transplant Research (CIBMTR) database. Methods Between July 2009 and May 2012, 43 eligible patients received BuMelVel conditioning followed by HCT. Bu was administered daily intravenous (IV) for a total of 4 days with the first 2 days (day -6, -5) at fixed dose of 130 mg/m2 over 3 hours and the subsequent 2 doses (day -4, -3) adjusted to achieve a target area under the concentration-time curve (AUC) total of 20,000 mM* min by performing pharmacokinetic (PK) analysis after the first dose of IV Bu. Mel 140 mg/m2 and Vel 1.6 mg/m2 were administered IV on Day-2 and Day -1 respectively. Outcomes were compared with a contemporaneous North American cohort (n=162) receiving single agent MEL 200 conditioning from the CIBMTR database. Controls were matched on age, sex, Karnofsky performance status (KPS), stage and interval from diagnosis to HCT. Multivariate analysis of Relapse, PFS, and overall survival (OS) was performed. Median follow up of survivors was 25 months. Planned maintenance therapy was not used. Results Age, gender, KPS, isotype, and stage were similar between groups (Table 1.). The MEL 200 cohort had more standard risk patients per Mayo Stratification of Myeloma and Risk-Adapted Therapy (mSMART) (78% vs. 40% in BuMelVel, p <0.0001) and more patients with only 1 prior line of therapy pre-HCT (67% vs. 47%, p = 0.02). Platelet and neutrophil engraftment kinetics were similar. Veno-occlusive disease (VOD) was not observed in the BuMelVel group and there was no non-relapse mortality (NRM). The incidence of relapse and PFS at 1 year were superior in the BuMelVel cohort (Table 1.). OS was similar between the cohorts. In multivariate analysis, PFS was superior in the BuMelVel cohort (HR for relapse/death in MEL 200 =1.87, p=0.04). Lack of a very good partial response or higher (≥VGPR) prior to HCT was associated with inferior PFS whereas lower KPS (<80) and higher international stage were associated with mortality. Conclusion PK directed dosing of Bu can be safely combined with Mel 140 followed by bortezomib without higher risk of VOD or NRM and in the absence of maintenance therapy. Within the constraints of a short follow up and uncontrolled post-transplant salvage therapies on both groups, no difference in OS has yet been observed. This novel conditioning regimen is safe and was associated with superior PFS compared with similarly matched controls and warrants further testing.

Abstract Abstract 4158 Background: High-dose chemotherapy followed by autologous hematopoietic cell transplantation (HCT) is a preferred primary treatment approach for those patients who have adequate organ function and performance status. We previously reported the use of melphalan + bortezomib conditioning regimen for tandem transplants in a different group of patients with refractory myeloma (Alekshun, et al. ASH 2007). In this study, we examine the effects of adding bortezomib to standard high-dose melphalan in patients with newly diagnosed myeloma who have chemosensitive disease. Methods: Thirty five newly diagnosed multiple myeloma patients with responsive disease (partial response (PR) or better) to induction therapy were enrolled to the study from January 2010 to June 2011. Patients received high-dose melphalan conditioning at 100 mg/m2 IV for 2 days, immediately followed by 1 dose of bortezomib at 1.3 mg/m2 (Mel/Vel). Those patients who achieved PR post induction were considered for tandem autologous transplant with Mel/Vel conditioning. Results: To date, 35 patients received autologous HCT conditioned with Mel/Vel, and 32 are evaluable for response. Median age is 56 years (range, 25 – 72) with the following disease characteristics: IgG (n=21), IgA (n=8), IgD (n=1), light chain (n=5). High-risk cytogenetics/FISH were seen in 13 patients (37%). Median beta-2 microglobulin was 3.5 (range, 1.3 – 34.8). Sixteen patients received bortezomib-based induction, 9 patients received lenalidomide-based therapy and 10 received both bortezomib and lenalidomide. Median time from initiation of induction to transplant was 221 days (range, 134 – 664). Responses to induction therapy were stringent CR (n=10), CR (n=4), very good partial response (VGPR) (n=13), and PR (n=8). Median CD34 cell dose is 4.86 × 106/kg (range, 2 – 20.08). Neutrophil engraftment was achieved after a median of 11 days (range, 10 – 14) and platelet engraftment occurred after a median of 16 days (range, 11 – 19). Two patients received tandem HCT. Best responses post transplant were sCR (n=19), CR (n=3), VGPR (n=7), PR (n=1) and progressive disease (n=2). The one year progression-free survival (PFS) estimate is 77% (95% CI 0.59 – 0.95) and one year overall survival (OS) estimate is 96% (95% CI 0.88 – 1.00) with a median follow-up of 279 days (range, 47 – 515). We did not detect significant differences in OS (p=0.69) stratified by cytogenetic/FISH risk status. Conclusions: The combination of bortezomib and high-dose melphalan (Mel/Vel) as conditioning regimen for autologous HCT is well tolerated and appears to improve responses post transplant. This early result is encouraging and the regimen will be examined in expanded cohort of patients. Disclosures: Baz: Millenium: Research Funding, Speakers Bureau; Celgene: Research Funding.

Abstract Background: Carfilzomib has significant activity in newly diagnosed Multiple Myeloma (MM). We present an update of a Phase 2 trial of dose-escalated Carfilzomib combined with Thalidomide and Dexamethasone (CTd). Introduction: This investigator sponsored, dose escalation phase 2 trial was designed to evaluate the clinical efficacy of standard dose Carfilzomib (C) (20/27 mg/m2) combined with Thalidomide (T) and Dexamethasone (D) (CTd) as induction therapy followed by high-dose Melphalan and autologous stem cell transplantation (ASCT), followed by consolidation therapy with CTd in transplant eligible patients with newly diagnosed symptomatic MM,. The second objective was to establish the maximum tolerated dose of Carfilzomib in this combination. Fifty patients were included in the first part who received 4 cycles of C at 20 mg/m2 i.v. on days 1 & 2 followed by 27 mg/m2 on days 8, 9, 15, 16 of cycle 1 and on days 1, 2, 8, 9, 15 & 16 of all subsequent 28-day cycles, T 200 mg p.o. days 1 through 28 of a 28 day cycle and D 40 mg p.o. on days 1, 8, 15 & 22 of a 28 day cycle. In the second part 3 cohorts of 20 patients each were treated with escalated dose of C at 20/36 mg/m2,20/45 mg/m2 and 20/56mg/m2, respectively with T and D at the same dose. Stem cell harvest was performed with cyclophosphamide 2 g/m2 and G-CSF. Patients received high-dose Melphalan (HDM, 200 mg/m2) and ASCT, followed by consolidation therapy consisting of 4 cycles CTd with C 27 mg/m2 (part1, n=50) or 36 mg/m2 or 45 mg/m2 or 56 mg/m2 days 1, 2, 8, 9, 15 & 16 of a 28 day cycle, respectively, combined with T 50 mg days 1-28 of a 28 day cycle and D 20 mg days 1, 8, 15, 22 of a 28 day cycle. Thrombosis prophylaxis was prescribed. The primary endpoint was very good partial response (VGPR) after 4 CTd cycles: secondary endpoints were complete response (CR), stringent CR (sCR) and overall response (≥ PR) according to IMWG criteria pre- and post HDM, progression-free (PFS) and overall survival (OS). Results: 111 patients were included as of 1st July 2014. We here report the response of all cohorts with a median follow-up of 34, 19, 12 and 6 months, respectively. Median age was 58 yr and ISS stages II and III were 40% and 27%, respectively. The CTd regimen was well tolerated. Fifteen patients discontinued treatment because of non-eligibility (n=3), refusal (n=2), toxicity (n=7) or progression (n=3). Safety analysis was available for all treatments in cohorts 27mg/m2 through 45mg/m2 and for induction cycles in cohort 56mg/m2. Non-hematological SAEs for the two lower dose levels were infections (n=8), polyneuropathy gr 2 (n=5), cardiac (n=3) and tumor lysis syndrome (n=2) (ASH 2013). Non-hematological SAEs for dose level 45mg/m2 (n=22) included thrombosis (n=1), reversible gastrointestinal event (n=2) and infections (n=5). At dose level 56mg/m2 SAEs were thrombosis (n=2), infections (n=3), reversible cardiac event (n=1). In 111 patients 4 cardiac events were observed (2 grade 2, 2 grade 3) 3 of which resolved completely. Two patients discontinued therapy because of thrombosis (n=1) and pneumonia (n=1). Stem cell harvest was successfully accomplished with >3x10*6 CD34+ yield in 85/85 patients and HDM/ASCT was performed with complete hematologic recovery in 77/78 patients. The primary endpoint ≥VGPR and CR was achieved in 94% and 56% (27mg/m2), 75% and 65% (36mg/m2), 91% and 55% (45mg/m2), 75% and 20% (56mg/m2, induction only). Of 25 CRs in dose levels 36mg/m2 and 45mg/m2, 9 (36%) were stringent CR with no clonal plasma cells in bone marrow and negative serum-free lite. VGPR + CR increased from 63% after induction to 73% after HDM/ASCT and 86% after consolidation, respectively. For CR these figures were 18%, 34% and 58%, respectively. Overall response and CR were not significantly different between dose cohorts. Responses did not differ between poor risk (gain 1q or t(4;14) or del17p) and standard risk FISH. At a median follow-up of 21 months for dose levels 27mg/m2, 36mg/m2 and 45mg/m2 ,78% of patients are alive without progression or relapse. PFS at 18 months is 88 %. Three patients died of myeloma. There were 2 second primary malignancies. Analyses for revised ISS and molecular subgroups will be presented. Conclusion: C combined with T and D is a safe and effective regimen for newly diagnosed MM. Dosing of Carfilzomib up to 56mg/m2 was well tolerated. This trial was registered as NTR2422. Carfilzomib and an unrestricted study grant were provided by ONYX Pharmaceuticals, an Amgen subsidiary.

Abstract Background: Chemotherapy administration to obese patients poses significant challenges due to the potential for augmented toxicities. There are limited guidelines and literature available on the dosing of high-dose therapy followed by autologous hematopoietic cell transplantation (HCT) in obese patients and dosing practices vary widely. We conducted a single-center, retrospective cohort study to compare outcomes and toxicities after high-dose melphalan followed by autologous HCT among non-obese (body mass index [BMI] < 30 kg/m2), obese (BMI 30-34.9 kg/m2), and severely obese (BMI ≥ 35 kg/m2) multiple myeloma patients. Patients and Methods: A total of 462 consecutive patients transplanted between January 2004 and December 2011 were included. Patients who had received a tandem transplant and those with the diagnosis of amyloidosis were excluded. The primary endpoint of the study was to compare the incidence of non-relapse mortality (NRM) and overall survival (OS) rates across all three cohorts. Secondary endpoints included progression-free survival (PFS), incidence of relapse, hospital length of stay, hospital readmission rates, engraftment and grade 3 and 4 non-hematologic toxicities. Results: All three cohorts had similar baseline characteristics except for age ≤ 65 years (yrs) (severely obese 85.3%, obese 66.7%, non-obese 63%; p = 0.001), and the use of adjusted body weight for melphalan dosing (severely obese 41.2%, obese 25.7%, non-obese 4.5%; p < 0.0001). Across all three cohorts, there were no significant differences in NRM, relapse/progression, OS, PFS, engraftment, response to transplant, hospital length of stay, 30-day readmission rates, grade 3 to 4 nausea, vomiting, enteritis, or renal toxicity. In univariate analyses, Durie-Salmon Stage (DSS) 3 was the only independent predictor of inferior OS. DSS 3 and ≥ 2 lines of therapy were significant predictors of inferior PFS. In a multivariate analysis, DSS 3 (hazard ratio [HR] 2.28, 95% confidence interval [CI]: 1.01-5.13, p = 0.05), age > 65 yrs (HR 2.13, 95%CI: 1.19-3.82, p = 0.01), serum creatinine (Cr) ≥ 1 mg/dL were associated with higher NRM, whereas actual weight (AW) dosing was associated with decreased risk of NRM (HR 0.38, 95%CI: 0.19-0.72, p = 0.003). Additionally, age ≤ 65 yrs (HR 1.32, 95%CI: 1.03-1.71, p = 0.03), baseline serum Cr ≤ 1.5 mg/dL were associated with increased risk of relapse/progression, whereas disease status ≥ partial response prior to HCT (HR 0.71, 95%CI: 0.54-0.94, p = 0.02) and BMI ≥ 35 kg/m2 (HR 0.62, 95%CI: 0.44-0.87, p = 0.01) were associated with decreased risk of relapse/progression. In a subgroup analysis evaluating only patients with AW dosing of melphalan, febrile neutropenia was more common in non-obese patients compared to obese and severely obese patients (71.4% versus 56.4% and 62.5%, respectively; p = 0.03). Conclusions: High-dose melphalan and autologous HCT can be performed safely in obese myeloma patients and BMI of ≥ 30 kg/m2 does not appear to be associated with adverse transplant outcomes. Further analysis is needed to evaluate the effect of dose adjustments on outcomes.

Abstract Background The role of up-front consolidation for newly diagnosed, transplant eligible MM (NDMM) patients (pts) has not yet been prospectively addressed in the novel agents era. Methods The EMN02/HO95 trial was designed to randomly (R) compare (R1) 4 cycles of bortezomib-melphalan-prednisone (VMP) vs high-dose melphalan (HDM) and autologous stem cell transplantation (ASCT), either single or double, as intensification therapy after induction with bortezomib-cyclophosphamide-dexamethasone (VCD) (M Cavo et al, ASCO 2016, abstract #8000). A second randomization to consolidation therapy with 2 cycles of VRD vs no consolidation (R2) was performed after intensification, to be followed by lenalidomide maintenance (lenalidomide 10 mg continuously) until progression or toxicity in both arms. (VRD: bortezomib 1.3 mg/m2 intravenously days 1, 4, 8, 11; lenalidomide 25 mg orally days 1 - 21; dexamethasone 20 mg orally days 1, 2, 4, 5, 8, 9, 11, 12 of a 28 days cycle). Primary study end points were progression-free survival (PFS) from R1 and PFS from R2. A first planned interim analysis for R2 was performed in July 2016 when at least 33% (= 172) of the required events for PFS had been observed. Results From February 2011 to April 2014, 1510 pts aged ≤ 65 years with symptomatic MM were enrolled, of whom 1499 were eligible. Of these, 1211 were randomized (stratification by ISS stage) to VMP (505 pts) or HDM (1 or 2 ASCT) (706 pts). For R2 903 eligible patients were randomized to consolidation (459 pts) or no consolidation (444 pts). Median follow up from R2 was 25 months (maximum 53). Response status at time of R2 was ≥ CR (23%), ≥ VGPR (67%), ≥ PR (93%), and will be updated for status at start of maintenance. At the time of analysis, 258 events for PFS after R2 had been reported. 3-year. PFS from R2 was 62% in all patients, i.e., 60% without consolidation and 65% in patients with consolidation, and median PFS had not yet been reached. PFS from R2 with adjustment for R1 was prolonged in pts randomized to VRD (HR=0.78; 95% CI=0.61-1.00; P=0.045), a benefit retained across predefined subgroups with revised ISS stage III (HR=0.67; P=0.26) and in patients randomized in R1 to VMP (HR=0.76; P=0.19) and to HDM (HR=0.79; P=0.13). The benefit of consolidation was observed in patients with low-risk cytogenetics (HR=0.68; P=0.03), but not in patients with high-risk cytogenetics (del(17p) and/or t(4;14) and/or t(14;16); HR=1.03; P=0.91). At 3 years OS from R2 was 86% and 87%, respectively. Toxicity from VRD was limited with 5% CTCAE grade 4, mainly hematological. Conclusions Consolidation treatment with VRD followed by Lenalidomide maintenance until progression or toxicity shows promising results as compared to maintenance alone for younger NDMM pts, but further study follow-up is needed.

High Dose Melphalan

Abstract High-dose Melphalan (HDM) is the most commonly used conditioning regimen for autologous stem cell transplantation (ASCT) in newly diagnosed transplant-eligible Multiple Myeloma (MM) patients. Recent evidence suggests that the depth of response after induction therapy influences progression free survival (PFS) and, in most studies, overall survival (OS). Actually the effect of the inclusion of new drugs in the conditioning regimen for ASCT is still unknown. Phase I-II clinical study showed that the addition of Bortezomib (Bor) to HDM is safe and a promising conditioning regimen. Thus, in this study we analyzed a single center experience on the use of Bor in combination with HDM (Bor-HDM) as conditioning regimen before ASCT as frontline treatment in MM patients in order to evaluate the safety and the response rates of this combination regimen. We analyzed a total cohort of 48 newly diagnosed MM patients (25 females and 23 males; median age 60 years, range 42-70) admitted consecutively to our Bone Marrow Transplantation Center from 2008 to 2014. Regarding prognostic stratification, 25% of patients were classified as stage III according to International Staging System (ISS), and 12% exhibited high-risk cytogenetic features (defined by presence of del(17p) and/or t(4;14) and/or t(14;16)). All patients with the exception of three underwent to 3-drugs Bor-based induction therapy including Bor (median cumulative dose: 28.9 mg/m2), Thalidomide and Dexamethasone (VTD). After induction therapy and stem cell collection 28 out of 48 patients were treated with Bor-HDM, whereas 20 patients with HDM alone as conditioning regimen before ASCT. HDM was administered on day -2 (median dose: 200 mg/m2), and a single-dose Bortezomib at the dosage of 1.3 mg/m2 was administered on day -1 in the Bor-HDM group. Stem cells were reinfused on day 0 (median number of CD34+ infused: 3.3x106/Kg, range 1.86-6x106/Kg). Responses were evaluated at day 100 after ASCT, and definitions of response were used according to the International Myeloma Working Group (IMWG) Uniform Response Criteria for MM. Quantitative variables were compared by non-parametric Kruskal-Wallis and Mann-Whitney tests as appropriate and categorical variables were analyzed by Chi-square and Fisher's exact test. pvalue of <0.05 was considered significant. Any significant difference was not observed between Bor-HDM group vs HDM group, regarding age at diagnosis (p=0.77), sex (p=0.24), cumulative induction dose of Bortezomib (p=0.42), dose of Melphalan used for conditioning (p=0.16) and the median number of CD34+ cells infused (p=0.12). Distribution of ISS stage was similar in the two groups (p=0.14), as well as that of high-risk cytogenetic (p=0.14). Moreover the response rates after the induction therapy was not statistically different in the two groups of patients analyzed (sCR + CR: 19% in Bor-HDM group vs 26% in HDM group; VGPR: 33% vs 48%; PR: 48% vs 26%, p=0.22). Any significant difference on hematopoietic recovery rates was not observed in Bor-HDM as compared to HDM alone with a mean time to neutrophil recovery of 12 days (range 9-18) and to platelet recovery of 12 days (range 9-21) in both groups. Bor-HDM conditioning was well tolerated, without increase of neuropathy occurrence. Then we analyzed the response rate after ASCT, showing that the overall response rate (ORR) was significantly higher in Bor-HDM group as compared to HDM (sCR+CR: 56% in Bor-HDM vs 17% in HDM; VGPR 30% vs 28%; PR: 15% vs 56%, p=0.0072) with a higher number of "good quality" response (sCR + CR + VGPR: 86% vs 45%; p=0.0075). The number of sCR was also significantly higher in Bor-HDM as compared to HDM alone (23% vs 0%, p=0.067). Moreover an improvement of the response rate after ABMT was seen more frequently in the Bor-HDM group as compared to the HDM group (p=0.0063). We then observed that the number of patients that underwent tandem ASCT was higher in the HDM group (66% vs 41%), even not reaching a statistical significance. In conclusion, this retrospective analysis suggests that BOR-HDM is safe as conditioning regimen with a higher response rate after ASCT as compared to the standard HDM regimen giving the rational design for randomized studies needed to assess whether this conditioning regimen is superior to HDM alone.

Background: High-dose melphalan and autologous hematopoietic cell transplantation (HCT) remains a crucial treatment modality for patients with multiple myeloma (MM). Strategies to improve the conditioning regimen have been explored with addition of novel targeted therapies previously with limited success. Selinexor, an orally available selective inhibitor of nuclear export (SINE), targeting Exportin-1 (XPO-1), was recently approved by the Food and Drug Administration (FDA) for relapsed/refractory MM. Our pre-clinical data show synergy between selinexor and bifunctional alkylating agents in several MM models. Therefore, we hypothesized that the addition of selinexor to high-dose melaphalan would be safe and improve outcomes of autologous HCT in MM. Methods: We designed a single institution, standard 3+3 dose escalation phase 1 study to evaluate the combination of selinexor (given at 40 mg po (dose level 1); 60 mg (dose level 2); and 80 mg (dose level 3) on days -3 and -2 before melphalan) and high-dose melphalan (100 mg/m2 IV on days -3 and -2) as a conditioning regimen for autologous HCT in patients with MM achieving either partial response (PR) or very good partial response (VGPR) after less than 4 lines of systemic anti-myeloma chemotherapy (NCT02780609). The primary objective was to establish a maximum tolerated dose (MTD) and identify a recommended phase 2 dose (RP2D). Results: From 08/2017 to 03/2019, a total of 12 MM patients (pts) received autologous HCT under the phase 1 protocol at Moffitt Cancer Center. Baseline characteristics included: a median age of 57 (range, 43-69); M:F = 7:5; IgG subtype=9, light chain type=2, IgD subtype=1; 92% with Durie-Salmon stage 3; 22% with high-risk disease based on del17p/t(4;14) (2/9, n=3 with unknown risk); a median number of induction=1 (range, 1-2); all received bortezomib-based induction, 83% received immunomodulatory agent, 17% received daratumumab. Pre-HCT responses were PR=4; VGPR=8. Pts received a median of 4.16 (range, 2.16-5.73) million CD34+ cells/kg. Neutrophil engraftment occurred with a median of 11 (range 11-12) days, and a platelet engraftment with a median of 15 (range, 10-36) days. Three pts each entered in dose level 1 and 2; and 6 pts at dose level 3. One pt in dose level 2 did not receive dexamethasone on day -1 due to grade (G) 3 hyperglycemia. One pt in dose level 3 (80 mg selinexor) did not receive day -2 dose of selinexor due to liver function test (LFT) abnormality (ALT > 2x ULN) which was considered as dose-limiting toxicity (DLT) as second dose of selinexor was not given. LFTs normalized after HCT. Dose level 3 was expanded to 3 additional pts and no additional DLTs were observed. Treatment-related serious adverse events (SAEs) included: G3 febrile neutropenia=3, G3 diarrhea=1, G3 nausea=1, G3 small bowel obstruction=1, G3 acute kidney injury=1, G3 lung infection=1. Post-HCT responses at day +90 were complete response (CR)=2, VGPR=6, PR=3, and progression=1. CR conversion rate was 16.7% though phase 1 portion of the study was not powered to evaluate the CR rate. Therefore, RP2D was established as selinexor 80 mg on days -3 and -2. The study is proceeding to the phase 2 portion to assess the efficacy of this combination. Conclusions: The combination with selinexor 80 mg po with high-dose melphalan at 100 mg/m2 on days -3 and -2 (dose level 3) was well tolerated and engraftment kinetics were not altered. A phase 2 study of selinexor 80 mg with high-dose melphalan and autologous HCT is ongoing (NCT02780609). Disclosures Nishihori: Karyopharm: Research Funding; Novartis: Research Funding.

Abstract Background The randomised, open-label, phase III trial HOVON-50 was designed to evaluate the effect of thalidomide during induction and maintenance in newly diagnosed multiple myeloma patients. The previous analysis showed that thalidomide improved the primary endpoint EFS, but had no impact on OS (Lokhorst et al; Blood 2010 115: 1113-1120). Method Patients with Salmon & Durie stage II or III, age 18-65 years inclusive, were randomly assigned to arm A: 3 cycles of VAD (Vincristine, Adriamycin, Dexamethasone) or to arm B, 3 cycles of TAD (Thalidomide 200 orally, days 1-28 instead of Vincristine) Thalidomide was given from day 1 until 2 weeks before the stem cell mobilization with CAD (Cyclophosphamide 1000 mg/m2 iv day 1)and G-CSF. After induction therapy patients received 1 or 2 courses of high dose Melphalan (HDM) 200 mg/m2 with autologous stem cell rescue followed by maintenance therapy with alpha-Interferon (Arm A) or Thalidomide 50 mg daily (arm B) until relapse or progression. Between November 27, 2001 and May 31, 2005, 556 patients were randomised of which 536 patients were eligible for evaluation. As of July 2013 the median follow up of the 201 patients still alive is 99 months, range 65 – 130 months. Results The best responses achieved on protocol after extended follow-up were improved and significantly higher in the patients randomized to thalidomide: ≥ PR 88% vs 80 % (p<0.01), at least VGPR 66 % vs 55% (p<0.01), CR 31% vs 24 % (p=0.04), respectively. Similar to the previous analysis thalidomide improved EFS (censored at allo-SCT) from median 22 months to 33 months,; HR = 0.63, 95% CI [0.51 - 0.78], p<0.001) and PFS from median 25 to 33 months (HR =0.70, 95% CI [0.58 - 0.84], p<0.001). After 5 years of randomization the overall OS curves diverged and thalidomide improved median OS from 65 to 75 months. 10 years from randomization 27 % of patients randomized to alpha-Interferon are still alive and 35% of patients randomized to Thalidomide. For OS multivariate analysis showed prognostic significance for the whole group of patients for LDH (HR=1.52, 95% CI [1.15-2.00], P= 0.004) and ISS (HR=1.31, 95% CI [1.11-1.53, P=0.001]. For the secondary endpoint OS the thalidomide arm was superior when adjusted for covariates in multivariate analysis (HR = 0.80, 95% CI [0.64 – 0.99], P=0.045). The incidence of second primary malignancies (SPM) was similar between the two arms, as well as the actuarial probability to get an SPM within 5 years from start of the therapy (5-6%) or 10 years (9-10%) Conclusion After long term follow-up thalidomide in induction and maintenance treatment and in combination with HDM improves the quality of response and achieves superior EFS and OS. No increased incidence of SPM was observed as compared to patients not receiving thalidomide. This trial was registered on www. Trialregister.nl as NTR238 and was supported by the Dutch Cancer Foundation.

Abstract Abstract 4576 Introduction: High dose chemotherapy followed by autologous hematopoietic cell transplantation (auto HCT) for multiple myeloma (MM) has shown improved survival compared to conventional chemotherapy. However, the larger clinical trials evaluating the role of auto HCT in MM have included patients who are generally younger than 65 years. Here we report the results of MM patients, age ≥70 years, who received auto HCT at our institution. Methods: We retrospectively analyzed 84 patients, who underwent auto HCT between January 1999 and June 2010 at MDACC. Conditioning regimen was Melphalan 140 mg/m2 (MEL 140) (N=9), 180 mg/m2 (MEL 180) (N=20), and 200 mg/m2 (MEL 200) (N=55). Disease response was assessed at day 100 post transplant. Results: Pertinent patient and disease characteristics are summarized in the Table. Median age at transplant was 72 (70-80) years. Median number of prior treatments was 1 (range: 1–8). Median time from diagnosis to transplant was 8.5 (2.4-151) months. No patient was in CR prior to auto HCT. Median CD34+ cell count and TNC was 4.56 (0.72-11.1) × 106/kg and 10.53 (2.25-57) ×108/kg, respectively. Median follow up is 2 (0.1-7.3) years. Grade III-IV organ toxicity was seen in 35 (51%) patients. Grade III-IV toxicity in patients who received MEL 140, MEL 180, and MEL 200 was 25%, 45%, and 44%, respectively (p value > 0.05). Non-relapse mortality (NRM) at 100 days was 2%. Two patients died in first 100 days. Disease response in evaluable patients (N=79) at day 100 was: CR=15 (19%); VGPR=7 (9%); PR=41 (52%); and SD=10 (13%). Median progression free survival (PFS) and overall survival (OS) from auto HCT was 2.1 years (95% CI 1.78–3.69) and 5.6 years (95% CI 5.51-NA), respectively. 2-year PFS and OS were 56% (95% CI 0.44–0.71) and 80% (95% CI 0.7–0.91), respectively. There was no difference in NRM, PFS, or OS in different MEL groups. Similarly there was no difference in TRM, PFS, and OS in patients ≥ 75 years compared to the patients < 75 years. Conclusion: Auto HCT in myeloma patients age ≥ 70 years is safe and feasible. Toxicity, NRM, response and survival were comparable to younger myeloma patients. The age alone should not be a contraindication for auto HCT.
