Abstract Introduction A phase 2 dose escalation trial of Carfilzomib in combination with Thalidomide and Dexamethasone (KTd) for induction and consolidation in newly diagnosed, transplant-eligible patients with multiple myeloma (MM). We report the results of 4 dose levels. Methods In this multicenter, open-label, phase 2 trial, transplant-eligible patients aged between 18 and 65 years with previously untreated symptomatic MM were included. Patients were treated with 4 cycles of escalating dose of Carfilzomib + fixed-dose thalidomide and dexamethasone (KTd) for induction therapy. The dose of Carfilzomib was 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 and 16 of cycles 2 to 4. Thalidomide dose was 200 mg orally on days 1 through 28 and Dexamethasone 40 mg orally on days 1, 8, 15 and 22. Carfilzomib was escalated to 20/36 mg/m2 in cohort 2, to 20/45 mg/m2 in cohort 3 and to 20/56 mg/m2 in cohort 4. Induction was followed by stem cell harvest after Cyclophosphamide priming (2 to 4 mg/m2) and G-CSF. Hereafter patients received high-dose Melphalan (HDM, 200mg/m2) and autologous stem cell transplantation followed by consolidation treatment with 4 cycles of KTd in the same schedule except a lower dose of Thalidomide (50mg). The primary endpoint was response after induction therapy and overall, specifically complete response (CR) and very good partial response (VGPR). Secondary endpoints were safety, progression-free survival (PFS) and overall survival (OS). Results All 111 patients with a median follow-up of 55, 42, 35 and 28 months, in cohorts 1 to 4, respectively were included in the analysis. Median age was 58 years. ISS stages I/II/III were 41%/34%/23%, respectively, R-ISS stages I/II/III/unknown were 23%/59%/9%/9%, respectively. Of 111 patients, 9 patients stopped treatment during/after induction, 8 patients after cyclophosphamide priming or HDM and 9 patients during consolidation because of toxicity (n=9), non-eligibility for further treatment (n=6), progression (n=5), refusal (n=2) or other reasons (n=4). Overall response rate for all cohorts was 95%. Response after induction was CR/sCR in 18% of patients, ≥ VGPR in 66% of patients, ≥ PR in 94% of patients. After HDM the CR/sCR rate increased to 31% and after consolidation to 64%. Responses between cohorts were in general comparable. See Table 1. Response based on risk status by ISS/FISH in either cohort and accumulated did not show a difference in CR/sCR rate after consolidation between standard-risk (67%) and high risk defined as t(4;14) and/or del17p and/or add1q and/or ISS3 (60%). OS at 30 months was comparable between standard risk and high risk, 91% versus 90%. PFS at 30 months for standard risk and high risk was 79% and 62%, logrank p=0.02 (HR=2.3, 95% CI=1.1-4.5). PFS at 30 months per cohort was 70% (95% CI, 55% to 81%), 70% (95% CI, 45% to 85%), 80% (95% CI, 56% to 92%) and 62% (95% CI, 32% to 82%) in cohorts 1,2, 3 and 4, respectively, and 71% (95% CI, 61% to 79%) in all patients. OS at 30 months per cohort was 90% (95% CI, 77% to 96%), 90% (95% CI, 66% to 97%), 95% (95% CI, 71% to 99%) and 88% (95% CI, 58% to 97%) respectively, and 91% (95% CI, 83% to 95%) in all patients. Gene expression profiling using the Affymetrix U133 Plus 2.0 GeneChips was performed on purified tumor cells for 49 patients. Using the prognostic classifier EMC92 a high-risk group of patients (16%) was identified versus standard risk (in terms of OS: logrank p=0.06 (HR=3.7, 95% CI=0.8-16.8), and in terms of PFS: logrank p=0.14 (HR=2.1, 95% CI=0.8-6.0)). Safety analysis for all 111 patients showed non-hematological grade 3 and 4 toxicity, mainly respiratory disorders (in 15%), GI disorders (13%) and skin lesions (10%). Toxicity between cohorts did not show a significant difference. Cardiac adverse events were limited and included heart failure (n=2 at 27 mg/m2), hypertension (n=2) and chest pain (n=1 at 45mg/m2). Conclusion Carfilzomib, thalidomide, dexamethasone (KTd) is an effective regimen, with increasing CR percentages following KTd consolidation. With escalated doses of Carfilzomib responses and toxicity were comparable to standard dose of 27 mg/m2.

Abstract Introduction : Daratumumab (DARA), a human IgG1k monoclonal antibody with single activity in multiple myeloma (MM) shows strong synergy in combination with other anti-MM agents, including immunomodulatory drug (IMiDs) and proteasome inhibitors (PI). This has led to the exploration of DARA in combination with front line regimens. Triplets including a PI and an IMiD are considered an ideal backbone with which to combine DARA prior to Autologous Stem Cell Transplantation (ASCT). However, based on the ability of Cyclophosphamide (Cy) to enhance DARA mediated antibody dependent cellular phagocytosis, we hypothesized that CyBorD may provide an alternative option (Naicker, ASH 2017). We are currently exploring the preliminary safety and efficacy of CyBorD and DARA as part of an ongoing phase 1b study in newly diagnosed MM (NDMM) pts eligible for ASCT. Last year we reported on the safety of this combination with an absence of dose limiting toxicity (DLT) with weekly subcutaneous (SQ) Bortezomib (Bor) 1.5mg/m2, Cy 300mg/m2 and DARA 16mg/kg (McEllistrim, ASH 2017). We now report on the efficacy of this regimen as pre-transplant induction, including the rate of CR post ASCT. Methods : Pts received 4 cycles of induction therapy with weekly CyBorD and DARA 16mg/kg weekly for cycles 1 and 2 and every 2 weeks for cycles 3 and 4. Following induction therapy, pts proceeded to stem cell mobilization and ASCT followed by 2 cycles of consolidation therapy with weekly CyBorD plus DARA 16mg/kg on days 1 and 15. Following completion of consolidation therapy, all pts receive DARA maintenance every 28-days for 2 yrs or until progression, unacceptable toxicity or withdrawal of consent. Pts with high-risk features receive Bor on days 1 and 15 during maintenance phase. The primary endpoints were the incidence of DLT within the first cycle of combination at each dose level and CR rate post ASCT. Secondary endpoints included: safety, CR rate at the end of induction, consolidation and maintenance, best overall response, minimal residual disease (MRD) negative rate, progression-free survival, clinical benefit rate and overall survival. Responses were investigator-assessed as per IMWG criteria. This trial is registered at www.clinicaltrials.gov as NCT02955810. Results : Eighteen pts were enrolled between Nov 2016 and Dec 2017 and received at least 1 dose of treatment. Baseline characteristics were: median age = 56 y (range 32-66); M (61%), F (39%), ISS stage I, II, III in 78%, 17% and 6% of pts, respectively. 28% patients were identified with high risk genetic features [17p deletion and/or t(4;14) by FISH and/or SKY92 (SkylineDx)]. Three patients discontinued therapy early (primary refractory, persistent liver toxicity, death, respectively). Overall, treatment was well tolerated. The most common grade (gr) 3/4 hematologic treatment emergent adverse events (TEAE) were lymphopenia (44%), neutropenia (11%) and anemia (11%). The most common gr 3/4 non-hematologic TEAE were diarrhea (11%) and infection (61%). One patient died from gr 5 diffuse alveolar damage 7 weeks post ASCT. A single patient developed gr 3 liver toxicity. DARA-associated infusion reactions were ≤ gr 2 (11%). On an intent to treat (ITT) basis 94% achieved ≥ very good partial response (VGPR) with ≥ complete response (CR) in 44% pts (Figure). Among the sixteen patients completing 4 cycles of induction ORR was 100%, ≥ VGPR (69%), ≥ CR (13%). Informative NGS data (Adaptive Biotech) are available on 11/16 patients post induction, of whom 100% are MRD negative post induction at a level of ≥ 10e4. Following the induction phase 15/16 patients readily mobilized sufficient CD34 positive progenitors and proceeded to ASCT, one patient failed repeated mobilization. One patient died prior to post ASCT response assessment and data on the last patient is pending. Thus 13/15 patients are currently evaluable for response post ASCT. Responses deepened post ASCT with 100% achieving ≥ VGPR and 62% achieving ≥ CR. Based on EBMT criteria the CR/nCR rate post ASCT was 92%. Post ASCT PET-CT scans were consistent with complete metabolic response in all 13 patients. Updated results, including MRD status post ASCT will be presented at the meeting. Conclusions: CyBorD-DARA is a highly active, well tolerated induction therapy for NDMM patients undergoing ASCT. These data support the further development of this combination as a convenient, cost effective alternative to PI-IMiD-DARA based combinations. Disclosures Quinn: Janssen: Honoraria.

Abstract Introduction: Lenalidomide, bortezomib and dexamethasone (RVD) is considered a new standard of care regimen for patients with newly diagnosed multiple myeloma. A previous phase I/II study of RVD in front-line myeloma enrolled 66 patients and achieved a partial response rate or better of 100%, overall and a CR/nCR rate of 52% in the phase 2 portion of the study with encouraging tolerability, but high rates of peripheral neuropathy (PN), albeit mainly mild to moderate grade (Richardson et al, Blood 2010). Subcutaneous (SQ) administration of single agent bortezomib has been shown to be non-inferior to IV bortezomib and led to lower rates of PN, a common treatment-related toxicity (Moreau et al, Lancet Oncol 2011). Herein we present preliminary results of the RsqVD Study, a multi-center, open-label single arm phase II trial, incorporating SQ bortezomib with lenalidomide and dexamethasone and including patients who were considered either transplant eligible or ineligible. All patients subsequently received maintenance therapy with lenalidomide until progression, plus the addition of subcutaneous bortezomib twice monthly in high risk patients (ISS stage II or III and/or high risk cytogenetics features, t(4;14, t(14;16) and del17p). The primary endpoint was overall response rate (ORR) after 4 cycles of induction therapy (PR or better). Secondary endpoints include: rate and severity of PN, safety, time to progression, progression-free survival, duration of response and overall survival. Methods: Planned treatment was 4 cycles of lenalidomide 25 mg/day on days 1-14 and dexamethasone 20/mg/day on days 1, 2, 4, 5, 8, 9, 11 and 12 plus bortezomib 1.3 mg/m2as SQ injection on days 1, 4, 8 and 11 of a 21-day cycle. Thromboprophylaxis with aspirin 75 mg/day or higher was mandatory and HSV prophylaxis was as per institutional standard. Following 4 cycles, patients were planned to proceed with stem cell mobilization and autologous stem cell transplant (ASCT) or further induction therapy up to a total of 8 cycles. Following completion of ASCT or induction therapy, all patients were scheduled to receive lenalidomide maintenance in 28 - day cycle until progression, unacceptable toxicity or withdrawal of consent. Patients with high-risk features received SQ bortezomib on days 1 and 15 during maintenance phase. Response was investigator-assessed as per IMWG criteria. Sample size (n=42) was determined to provide 80% power to test an acceptable ORR of >70% versus an unacceptable ORR of <50% (1-sided alpha=0.05) including an estimated drop-out rate of 10%. Results: Between November 2014 and February 2016, 42 patients were enrolled across 8 sites in Ireland. Baseline demographic factors include: 64% males, 36% females; median age of 64 years (45-79 years); 41% ISS stage I, 59% ISS stage II/III. FISH analysis detected t(4;14) in 18% of patients (7/40), t(14;16) in 3% of patients (1/36) and del17p in 10% of patients (4/40). 64% (27/42) patients proceeded to stem cell mobilization and 60% (25/42) to ASCT. The median number of induction cycles completed was 4 (1 to 8 cycles). 40 of a total of 42 patients were considered evaluable for the primary endpoint of ORR. A preliminary analysis of ORR following 4 cycles of induction therapy indicates that 98% (39/40) of patients achieved partial response or better. PN of any grade has been reported by sites in 43% (18/42) of patients to date. Conclusion: RsqVD is a highly effective regimen in newly diagnosed multiple myeloma producing a very high ORR following initial induction therapy, with a lower overall rate of PN described by sites than expected. Full analyses of response and safety data for induction treatment and follow up will be presented, as well as preliminary evaluation of response to subsequent therapy.

Abstract Abstract 3982 Newly diagnosed multiple myeloma (MM) patients (pts) with t(4;14) identified by FISH who undergo a single ASCT after older induction regimens have a median progression-free survival (PFS) of only 8–9 months (mos) and median overall survival (OS) of 18 mos (Chang H, et al. Bone Marrow Transplan t 2005; 36: 793; Gertz M, et al. Blood 2005; 106: 2837). Given the efficacy of bortezomib in t(4;14) disease, we designed a phase II study based on this agent in which ASCT was not performed as part of first-line therapy. Pts received induction therapy with four 21-day cycles of pegylated liposomal doxorubicin 30 mg/m2on day 4, bortezomib 1.3 mg/m2on days 1, 4, 8, 11 and dexamethasone 40 mg on days 1–4, 8–11, 15–18 of cycle 1 and on days 1–4 and 11–14 of cycles 2–4 (DBD), followed by post-induction therapy with eight 28-day cycles of oral cyclophosphamide 300 mg/m2on days 1, 8, 15, 22, bortezomib 1.5 mg/m2 on days 1,8,15 and prednisone 100 mg q 2 days (CyBor-P). Maintenance therapy with dexamethasone 40 mg/weekly was then administered until disease progression. Although elective stem cell collection was recommended after induction therapy, routine ASCT was not performed in the absence of disease progression. Between February 2008-May 2011, 383 newly diagnosed MM pts were screened for t(4;14) in 8 Canadian centers, and 43 (11.2%) were found to be positive by FISH. Five did not meet the CRAB criteria for symptomatic MM, 7 were ineligible, 3 declined participation and 28 were entered onto study. One of these was later determined to have a variant abnormality of chromosome 4, but not t(4;14), and underwent ASCT after induction therapy; this pt is included in the safety analysis only. The median age was 60 years (range 42–69) and 63% were male. The median percent of nuclei positive for t(4;14) by FISH in the initial bone marrow (unpurified) was 26% (range 2–62), serum β2-microglobulin 239 nmol/L (range 43–1695) and albumin 36 g/L (range 28–48); ten pts had ISS stage 1,10 had stage 2 and 7 had stage 3 MM. Immunoglobulin subtype included IgGκ in 7, IgAκ in 6, IgAλ in 6, IgGλ in 5 and IgMλ in 1. Using modified uniform criteria, the best response in 23 evaluable pts includes: sCR in 6 (26%), CR in 4 (17%), VGPR in 9 (39%), PR in 2 (9%) and SD in 2 (9%). Median F/U is 13.5 mos (range 1.2–35); 6 have progressed at median of 3 mos on study (range 1–11). Four pts have died (due to progression in 3 and complex medical problems/consent withdrawal in 1 in VGPR). SAEs were reported in 7 pts; only 6 pts (21%) developed grade 2 peripheral neuropathy, which necessitated dose reductions of bortezomib in 4. The actuarial 2-yr PFS is 47.7% (95%CI 25.9–87.9%), median PFS is 23. 2 months and 2-yr OS is 76.8% (95%CI 58.3–100%); the median OS has not yet been reached. We conclude: 1) the incidence of t(4;14) by FISH in newly-diagnosed MM pts is 11.2%; which appears to be lower than the 15% anticipated 2) 11.6% of these are asymptomatic; 3) this bortezomib-based regimen is well-tolerated; 4) the overall response rate (sCR + CR + VGPR + PR) is 91% with 82% achieving ≥ VGPR and 43% ≥ CR; 5) the PFS and OS with this approach compare favorably with those seen with older studies of single or double ASCT, and even with some recently reported trials using more modern induction regimens before ASCT, in pts with t(4;14); and 6) the use of more effective maintenance therapy, including agents targeting the aberrations associated with t(4;14), would be of interest in future trials.

Abstract Background Multiple Myeloma (MM) is a clinically heterogeneous disorder of clonal plasma cells. Elevated Lactate Dehydrogenase (LDH) has been shown to be an independent prognostic marker associated with drug resistance and shorter survival. Methods Utilizing data from the Multiple Myeloma Research Foundation (MMRF) CoMMpass database (IA12) which includes over 1000 newly-diagnosed MM (NDMM) patients with enriched tumor and matched constitutional samples analyzed using whole genome/exome and RNA sequencing, we identified patients with baseline LDH values. High LDH was defined as LDH greater than the upper limit of normal, (>4.68 microkatals/liter). We compared baseline characteristics and outcomes with autologous stem cell transplant (ASCT), based on LDH as categorical variable. We sought to determine if there is enrichment of high and standard risk cytogenetic changes when stratified by LDH. Results We identified 871 patients with NDMM who had baseline LDH values. 143 patients had high LDH and 728 patients had a normal baseline LDH. Consistent with prior reports, high LDH was associated with shortened survival, 660 days vs 795 days (p=0.02852) in patients with normal LDH. 385 patients underwent ASCT (High LDH N=44; Normal LDH N=341). Those with high LDH had an inferior OS when compared with those with normal LDH (median OS 800.5 vs 878.8 days, p=0.019). In order to understand this difference, we examined baseline characteristics. Of the 44 patients with high LDH who underwent ASCT, median age was 60 years and ECOG performance status was 1. 61.36% were females, 77% were Caucasian, 11% were African American. Induction therapy consisted of 4 drugs or more in 16%, 3 drugs in 61%, and 2 drugs in 23%. Bortezomib and immune modulating agents (IMIDS) were combined in 72%. In those who did not receive an IMID, a bortezomib-based induction was used in 16% and carfilzomib-based induction was used in 11%. 93.18% underwent transplant in the consolidative setting with a median time to transplant was 178 days. 21 of the 44 patients (47.72%) received post-transplant maintenance. 10/21(48%) patients received triplet therapy (5/10 - lenalidomide, bortezomib, dexamethasone), 8/21 (38%) patients received lenalidomide alone. The median duration of maintenance was 217 days. Of the 341 patients with normal LDH who underwent ASCT, the median age was age 61 years, ECOG performance status was 1. 41.34% were females, 79% were Caucasian, 13% African American. Induction therapy consisted of 4 drugs in 8%, 3 drugs in 64%, 2 drugs in 24%. Combined Bortezomib-IMID in 76.24%, carfilzomib-IMID based therapy in 6%, and bortezomib-non-IMID based in 9.67%. 94.7% underwent an upfront consolidative with median time to transplant 164 days. Post-transplant maintenance was given in 213/341 (62.4%) of patients, in whom triplet therapy was given to 41/213 (19.2%), doublet therapy to 34/213 (16%), 130/213 (61%) received single agent. 107/213 (50%) received lenalidomide alone and 19/213 (6%) received bortezomib alone. Median duration of maintenance 266 days. There was no statistically significant difference in race, performance status, drug class and number of drugs used in induction therapy, time to transplant, whether or not patients received maintenance as well as maintenance duration between the groups when stratified by LDH. Female gender was enriched in the high LDH group (hypergeometric test, p=0.009). We used hypergeometric tests to assess for enrichment of high and standard risk cytogenetic changes. Del(17p13) was significantly enriched (p=0.011) in the high LDH subset where there were no statistically significant difference in the presence of t(4;14) (p=0.16) and t(14;16) (p=0.21). There was no difference in good risk hyperdiploid structural changes between the 2 groups. Conclusion Elevated LDH was confirmed as a poor prognostic factor in MMRF CoMMpass cohort. Among patients who underwent ASCT, those with high LDH have inferior survival, possibly driven by the presence of del(17p13). Since clinical outcomes remain poor despite the use of novel effective therapies and early consolidation with AHCT in patients with high baseline LDH, this group represents an unmet need for alternative therapy.

Abstract Background Progression free and overall survival (PFS/OS) for Multiple Myeloma (MM) have improved over the past 20 years largely as a result of ASCT as well as novel conventional dose therapeutic agents. However, since the 1990s improvements in PFS and OS due to ASCT have improved minimally due to continued reliance on single agent melphalan (MEL). In order to improve PFS and OS, better transplant regimens should be investigated. The combination of Busulfan (BU) and MEL delivers better PFS compared to MEL alone (Lahuerta, et al) with similar toxicity rates to MEL alone. Furthermore, in vitro and in vivo studies indicate synergy between MEL and proteasome inhibitors such as Botezomib (BTZ). Superior response rates and PFS were seen when BTZ is combined with MEL when compared with historical controls using MEL in a recent IFM study. (Roussel et al. Blood 2010). We hypothesize that IV BU and MEL followed by BTZ (BuMelVel) could be an effective preparative regimen with acceptable toxicity for patients with MM. Methods Between July 2009 and June 2013 57 patients with Multiple Myeloma who had already undergone induction therapy and were eligible for ASCT were enrolled. Patients received IV BU administered as a daily intravenous infusion 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. Pharmacokinetic (PK) analysis performed after the first dose of IV Bu was used to determine Bu AUC and individualized Bu PK-directed dosing for later doses (d-4 and -3). MEL was administered at 140 mg/ m2 IV over 15-30 minutes on D-2. BTZ 1.6 mg/m2 was administered IV push on D-1. Palifermin was given for mucoprotection at a dose of 6.25 mg IV for two consecutive days before the first busulfan dose (days -8 and -7). A third dose of 6.25 mg was give on day 0 after stem cell transplantation. Results Of the 57 patients enrolled 56 are evaluable for toxicity and 54 for response at D +100. Median age is 61 (31 - 72). 49 % of patients had received ≥ 2 induction regimens (range 1-4) and 69% were DS stage III. 38% of patients had achieved at least a VGPR after induction with 9% of those achieving a CR. After transplantation, 70% of patients had at least a VGPR including 37% CR or sCR. All but 4 patients had a PR or better to induction therapy (three had stable and one progressive disease). The most common grade ≥ 3 toxicities were neutropenic fever (n = 42) and mucositis (n=21). No VOD or treatment related deaths at D+100 were observed and all patients engrafted. Median time to engraftment was 10 days (range 10-12) and median hospital stay was 20 days ( 15-31). Median PFS at 2 years was 78%. Conclusion BuMelVel is an effective novel preparative regimen with ≥ VGPR and CR/sCR of 70% and 37% respectively which compare favorably to responses previously reported with MEL 200 alone (43% and 11%, respectively) by Roussel et al. At the time of reporting, 12 patients had relapsed; 2 and 3-year PFS rates were 78% and 60% respectively. The regimen of BuMelVel is well tolerated and may lead to improvements in PFS and OS in patients with multiple myeloma.

Abstract Background: The randomized PETHEMA/GEM phase III trial GEM05menos65 (www.clinicaltrials.gov NCT00461747) demonstrated that pretransplant induction therapy with VTD resulted in a significantly higher CR rate both, pretransplant and postransplant and in a significantly longer progression-free survival (PFS) when compared with thalidomide/dexamethasone (TD) and combination chemotherapy plus bortezomib (VBMCP/VBAD/B) (Rosiñol et al, Blood 2012). We report here the long-term results of the trial, five years after the last patient was included. Methods: From April 6, 2006 to August 5, 2009, 386 patients younger than 65 years with newly diagnosed symptomatic multiple myeloma (MM) were randomized to receive three different induction regimens: six 4-week cycles of TD (thalidomide 200 mg daily; dexamethasone 40 mg on days 1-4 and 9-12) vs. six 4-week cycles of VTD (TD at identical doses plus i.v. bortezomib 1.3 mg/m2 on days 1, 4, 8 and 11) vs. combination chemotherapy plus bortezomib (4 cycles of alternating VBMCP and VBAD chemotherapy followed by two cycles of i.v. bortezomib at the usual dose of 1.3 mg/m2 on days 1,4,8,11 every 3 weeks). The duration of the induction therapy was 24 weeks in all arms. All patients were planned to undergo ASCT with high-dose melphalan at 200 mg/m2 followed by maintenance therapy with thalidomide/bortezomib (TV) vs. thalidomide (T) vs. alfa-2b-interferon (alfa2-IFN) for 3 years. One-hundred and thirty patients were allocated to VTD, 127 to TD and 129 to VBMCP/VBAD/B. Seventy out of the 330 patients (21%) with cytogenetic studies had high-risk cytogenetics [t(4;14), t(14;16) and/or 17p deletion]. Patient characteristics at diagnosis and prognostic factors such as ISS, cytogenetics and maintenance arm were similarly distributed in the 3 arms. Results: After a median follow-up of 70.6 months, VTD resulted in a significantly longer PFS when compared with TD and VBMCP/VBAD/B (56.1 vs 29.2 vs 39.9 months, p=0.005) (Figure 1). The estimated overall survival (OS) at 8 years was 60% with no significant differences among the 3 arms. In the overall series, the PFS was significantly shorter in patients with high-risk cytogenetics compared with patients with standard-risk (15.7 vs. 44.3 months, p=0.003). In the TD and in the VBMCP/VBAD/B arm patients with high-risk cytogenetics had a significantly shorter PFS than patients with standard-risk (8.9 vs 32.8 months, p=0.04 in TD group; 14.1 vs. 43.3 months, p=0.05 in VBMCP/VBAD/B group). However, there was no significant difference in the VTD arm (23.6 vs 56.1 months, p=0.2). Patients with high-risk cytogenetics had a significantly shorter OS in the overall series (median 42.1 months vs not reached, p=0.00001) and this was observed in the three treatment arms: VTD median 37.1 months vs not reached (p=0.001), TD median 54.2 months vs not reached (p=0.06), VBMCP/VBAD/B median 30.2 months vs not reached (p=0.007). The achievement of a deeper response at the end of induction was associated with a longer PFS and OS. Thus, patients achieving CR at the end of induction had a significantly longer PFS than patients achieving a lower degree of response (median 62 vs. 28 months, p=0.00001), irrespective of the treatment arm. Furthermore, on an intention to treat basis, patients who were in postrasplant CR had a significantly longer PFS (p<0.00001) and OS (p<0.00001) than those who did not reach CR after ASCT (p<0.001). In the overall series the OS after progression was 30.5 months and was not significantly different among the 3 arms (VTD 25.4 months, TD 50 months, VBMCP/VBAD/B 30.2 months, p=0.4). Patients with high-risk cytogenetics had a significantly shorter OS after relapse in the overall series (13.3 months vs. 37.5 months, p=0.001), in the VTD arm (13.3 vs 33.9, p=0.01) and in the VBMCP/VBAD/B arm (8.5 vs 38 months, p=0.01). Conclusions: Our long-term results confirm that induction with VTD results in a significantly longer PFS when compared with TD and VBMCP/VBAD/B. Patients with high-risk cytogenetics had a worse outcome even with the use of novel drugs. Finally, the PFS of 56 months achieved with VTD is the longest ever reported in the first line treatment of younger patients with MM elegible for ASCT and support the use of VTD as the standard of care for pretransplant induction therapy.

Abstract Background The role of single vs double autologous stem cell transplantation (ASCT) in patients with newly diagnosed (ND) multiple myeloma (MM) needs to be prospectively investigated in the novel agent era. Methods The phase III EMN02/HO95 study was designed to compare (first randomization, R1) (stratification according to ISS stage) standard-dose intensification therapy with bortezomib-melphalan-prednisone (VMP) vs high-dose intensification therapy with melphalan at 200 mg/m2 (HDM) followed by ASCT after 3-4 cycles of bortezomib-cyclophosphamide-dexamethasone as induction therapy. A second randomization to consolidation therapy vs no consolidation was performed after intensification therapy, to be followed by lenalidomide maintenance until progression or toxicity in both arms. A primary study endpoint was progression-free survival (PFS) from R1. In centers with a policy of double ASCT, patients were randomized in a 1:1:1 ratio to either VMP or single ASCT (ASCT-1) or two sequential courses (administered 2 to 3 months apart) of HDM and double ASCT (ASCT-2) in order to prospectively compare ASCT-1 with ASCT-2, which was an additional study objective. Results From February 2011 to April 2014, 1510 pts aged ≤65 years with symptomatic NDMM were registered and 1192 of these were eligible for R1. According to the design of the study, 614 eligible patients who received the diagnosis of MM in centers with a double intensification policy were randomly assigned to either VMP (n=199) or ASCT-1 (n=208) or ASCT-2 (n=207). Patients randomized to ASCT-1 or ASCT-2 were included in the current pre-specified analysis. Median age was 59 years for patients in the ASCT-1 group and 57 years for those in the ASCT-2 group. The frequency of ISS stage III was 18% and 19%, while revised ISS stage III was 9% and 11%, respectively. Cytogenetic abnormalities were detected by FISH analysis of CD138+ plasma cells. A high-risk (HR) cytogenetic profile, defined by t(4;14) and/or del(17p) and/or t(14;16) (HR cyto-3), was observed in 26% of evaluable patients who were randomized to ASCT-1 and in 21% of those randomly assigned to ASCT-2. If amp(1q) and/or del(1p) were added for the definition of high-risk disease, a HR cytogenetic profile that included at least 1 of the 5 above mentioned chromosomal abnormalities (HR cyto-5) was reported in 55% of evaluable patients in the ASCT-1 group and in 54% of those in the ASCT-2 group. Median follow-up from R1 was 27 (IQR: 20-35) months. On an intention-to-treat basis, the median PFS was 45 months in the ASCT-1 arm and was not yet reached for patients in the ASCT-2 arm; 3-year estimates of PFS were 60% and 73%, respectively (HR=0.66; 95% CI=0.45-0.96; P=0.030). PFS benefit with ASCT-2 was retained across predefined subgroups, including patients with β2-microglobulin >3.5 mg/L (HR=0.59; CI=0.34-0.99; P=0.005), bone marrow plasma cells >60% (HR=0.41; CI=0.22-0.77; P=0.006), LDH values above the upper limits (HR=0.52; CI=0.28-095; P=0.034), revised ISS stage II (HR=0.50; CI=0.31-0.80; p=0.004), HR cyto-3 (HR=0.49; CI=0.24-1.02; P=0.057) and HR cyto-5 (HR=0.57; CI=0.35-0.93; P=0.024). In a multivariate Cox regression analysis stratified by ISS stage, randomization to ASCT-2 (HR=0.62; CI=0.40-0.95; P=0.027) and HR cyto-5 (HR=2.63; CI=1.63-4.16; P<0.001) were the leading independent predictors of PFS. Overall survival was not yet mature and no difference between the two treatment groups was evident. Conclusions Upfront double ASCT after bortezomib-based induction therapy for newly diagnosed MM was superior over a single ASCT in terms of prolonged PFS. Clinical benefits of double ASCT were mostly seen in patients with disease-related factors predicting for poor prognosis.

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.

Abstract Abstract 3069FN2 Background: High-dose chemotherapy with haemopoietic stem-cell improves outcome in multiple myeloma (MM). The introduction of novel agents questions the role of autologous stem-cell transplantation (ASCT) in MM patients. Aims: In this prospective randomized study, we compared conventional melphalan-prednisone-lenalidomide (MPR) with tandem high-dose melphalan (MEL200) in newly diagnosed MM patients younger than 65 years. Methods: All patients (N=402) received four 28-day cycles of lenalidomide (25 mg, d1-21) and low-dose dexamethasone (40 mg, d1, 8, 15, 22) (Rd) as induction. As consolidation, patients were randomized to MPR (N=202) consisting of six 28-day cycles of melphalan (0.18 mg/kg d1-4), prednisone (2 mg/kg d1-4) and lenalidomide (10 mg d1-21); or tandem melphalan 200 mg/m2 MEL200 (N=200) with stem-cell support. All patients enrolled were stratified according to International Staging System (stages 1 and 2 vs. stage 3) and age (<60 vs. ≥60 years). Progression-free survival (PFS) was the primary end point. Data were analyzed in intention-to-treat. Results: Response rates were similar: at least very good partial response (≥VGPR) rate was 60% with MPR vs. 58% with MEL200 (p=.24); the complete response (CR) rate was 20% with MPR vs. 25% with MEL200 (p=.49). After a median follow-up of 26 months, the 2-year PFS was 54% in MPR and 73% in MEL200 (HR=0.51, p<.001). The 2-year overall survival (OS) was similar in the two groups: 87% with MPR and 90% with MEL200 (HR 0.68, p=.19). In a subgroup analysis, MEL200 significantly prolonged PFS in both standard-risk patients without t(4;14) or t(14;16) or del17p abnormalities (2-year PFS was 46% in the MPR group vs. 78% in the MEL200 group, HR=0.57, p=.007) and high-risk patients with t(4;14) or t(14;16) or del17p abnormalities (2-year PFS was 27% for MPR vs. 71% for MEL200, HR=0.32, p=.004). In patients who achieved CR, the 2-year PFS was 66% for MPR vs. 87% for MEL200 (HR 0.26; p<.001); in those who achieved a partial response (PR), the 2-year PFS was 56% for MPR vs. 77% for MEL200 (HR 0.45; p<.001). In the MPR and MEL200 groups, G3-4 neutropenia was 55% vs. 89% (p<.001); G3-4 infections were 0% vs. 17% (p<.001); G3-4 gastrointestinal toxicity was 0% vs. 21% (p<.001); the incidence of second tumors was 0.5% in MPR patients and 1.5% in MEL200 patients (p=.12). Deep vein thrombosis rate was 2.44% with MPR vs. 1.13% with MEL200 (p=.43). Conclusions: PFS was significantly prolonged in the MEL200 group compared to MPR. This benefit was maintained in the subgroup of patients with standard- or high-risk cytogenetic features. Toxicities were significantly higher in the MEL200 group. This is the first report showing a PFS advantage for ASCT in comparison with conventional therapies including novel agents. These data will be updated at the meeting.

Abstract Background : Lenalidomide, bortezomib and dexamethasone (RVD) has been shown to be a well-tolerated and efficacious induction regimen in newly diagnosed myeloma patients. Two large randomized phase III trials show an overall response rate (ORR) >95% (Durie et al, Attal et al) supporting this combination regimen. We have conducted a retrospective analysis utilizing our institutional data of 1000 patients treated with RVD induction therapy at the Winship Cancer Institute of Emory University. Methods: 1000 newly diagnosed MM patients were treated with RVD induction therapy [R - 25 mg/day (days 1-14), V - 1.3 mg/m2 (days 1, 4 8, 11) and D - 40 mg once/twice weekly as tolerated every 21 days] from January 1st 2005 until August 31st 2016. Dose-adjustments were made based on the treating physician's discretion and patient tolerability. Demographic and outcomes data for the patients were obtained from our IRB approved myeloma database and responses were evaluated per IMWG Uniform Response Criteria. Results: The median age of this cohort was 61 years (range 16-83). Other notable patient characteristics include: M/F 54.3%/45.6%; W/AA 56.4%/34%; ISS I and II/III 54%/17%; Isotype IgG/IgA/FLC 59.1%/19%/15.8%; standard risk/high risk 72%/28%. High risk disease was defined as the presence of t(4;14), t(14;16), del(17p), and/or complex karyotype. A total of 835 patients (83.5%) underwent autologous stem cell transplant (ASCT) upfront after attaining at least a partial response with induction therapy, and 165 patients (16.5%) were offered deferred transplant. Among the patients that opted for deferred transplant, 56 of these patients (33.9%) underwent ASCT at first relapse with a median time to transplant of 30 months (3-96). 755 (75.5%) of patients received risk-stratified maintenance therapy following transplant. Evaluation of responses to induction therapy for the entire cohort show an ORR 97.3% with ≥VGPR of 68% post-induction therapy. Response rates 100 days post-transplant show an ORR 98% with 30.7% of patients achieving a sCR. Response rates are summarized in table 1. Median PFS was 63 months for the entire cohort, and 72 months for standard risk patients (61.75-82.25) versus 37 months for the high-risk patients (30.84-43.16), p<0.001. Median OS has not been reached at median of 38 months follow up (Figure 1). Conclusions: This is the largest reported cohort of myeloma patients treated with RVD induction. These results illustrate both the activity of this induction regimen with impressive response rates and long-term outcomes in both standard and high risk patients.
