Abstract Background Rd and MPR are effective treatments in newly diagnosed multiple myeloma (NDMM) patients (pts). In this study we compared a non-alkylating containing regimen (Rd) vs alkylating-based regimens (MPR/CPR) in elderly transplant ineligible NDMM pts. Methods Patients were randomized (2:1) to receive nine 28-day cycles of MPR/CPR or Rd. MPR: lenalidomide 10 mg/day for 21 days; melphalan orally 0.18 mg/Kg for 4 days in pts 65-75 years old and 0.13 mg/Kg in >75 years pts; prednisone 1.5 mg/Kg for 4 days; CPR: cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day (eod) in >75 years pts; lenalidomide 25 mg/day for 21 days; prednisone 25 mg every other day. Rd: lenalidomide 25 mg/day for 21 days; dexamethasone 40 mg on days 1,8,15 and 22 in pts 65-75 years old and 20 mg in those >75 years. After induction, patients were randomized to receive maintenance with lenalidomide alone (10 mg/day for 21 days) or with prednisone (25 mg eod on days 1-28), until disease progression. The primary endpoint was progression-free survival (PFS). Results Between October 2009 and October 2012, 659 pts were enrolled ( MPR/CPR:439 and Rd:220), and 641 pts were evaluable (MPR/CPR:430 and Rd:211). Patient characteristics were well balanced in the 2 groups: median age was 73 years in both groups, 38% of pts were older than 75 years, 27% had ISS stage III in both groups, 21% of patients both in the MPR/CPR and in the Rd groups had unfavorable FISH profile [t(4;14) or t (14;16) or del17p]. After induction, the response rates were similar in the 2 groups: at least PR rate was 75% versus 79% (p=0.52) and CR rate was 9% versus 7% (p=0.35), in the MPR/CPR and Rd group, respectively. No significant difference in response rate were reported between two alkylating containing regimens. After a median follow-up of 21 months, the 2-year PFS was 55% in MPR/CPR and 49% in Rd (HR=0.86, 95% CI: 0.66-1.12, p=0.26), and 2-year OS was 84% in MPR/CPR and 80% in Rd (HR= 0.93, 95% CI: 0.60-1.41, p=0.71) At least one grade ≥3 hematological adverse event was reported in 51% with MPR/CPR and 29% with Rd (p<0.001), with a significant difference between the two alkylating agents (67% MPR and 31% CPR, p<0.001). At least one grade ≥3 extra-hematologic toxicities were similar in the two groups (31% with MPR/CPR and 28% with Rd, p=0.77). with no difference between two alkylating agents (31% both in MPR and CPR group). Second primary malignancies (SPM) were reported in 5 MPR patients (1 hematologic and 4 solid) in 1 CPR patient (hematologic) and in 2 Rd patients (both solid). Conclusion In a community-based population, triplet alkylating combinations did not lead to different PFS or OS clinical benefits over doublet therapy. Updated results will be presented at the meeting.

Abstract Introduction : Rd and MPR showed to be effective combinations in elderly newly diagnosed multiple myeloma (NDMM) patients (pts). Cyclophosphamide is a less toxic alkylating alternative agent. EMN01 is the first trial to formally compare these three different Lenalidomide-based combinations. Maintenance with Lenalidomide has been recently approved in patients eligible for autologous stem cell transplant (ASCT). Few data are available about the best combination as maintenance in patients not eligible for ASCT. Methods : 662 pts with NDMM were randomized to receive 9 28-day cycles of Rd (lenalidomide 25 mg/day for 21 days; dexamethasone 40 mg on days 1,8,15 and 22 in pts 65-75 years old and 20 mg in those &gt;75 years), MPR (lenalidomide 10 mg/day for 21 days; melphalan orally 0.18 mg/Kg for 4 days in pts 65-75 years old and 0.13 mg/Kg in &gt;75 years pts; prednisone 1.5 mg/Kg for 4 days) or CPR (lenalidomide 25 mg/day for 21 days; cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day in &gt;75 years pts; prednisone 25 mg every other day). After induction, pts were randomized to receive maintenance with lenalidomide alone (R; 10 mg/day for 21 days) or with prednisone (RP; R, 10 mg/day for 21 days and P, 25 mg every other day), until disease progression. Results : Pts characteristics were well balanced in all groups; 217 pts in Rd, 217 in MPR and 220 in CPR arms could be evaluated. After a median follow-up of 63.7 months, median PFS was 23.2 months in MPR, 18.9 months in CPR and 18.6 months in Rd (MPR vs CPR p=0.02; MPR vs Rd p=0.08). Median overall survival (OS) was 79.9 months in MPR, 69.4 months in CPR and 68.1 months in Rd (MPR vs CPR p=0.98; MPR vs Rd p=0.64). The most common grade ≥3 adverse event (AEs) was neutropenia: 64% in MPR, 29% in CPR and 25% in Rd pts (p&lt;0.0001). Grade ≥3 non hematologic AEs were similar among arms. At the end of induction, 402 pts were eligible for maintenance, 198 in the RP and 204 in the R groups. PFS from start of maintenance was 22.2 months in the RP group and 17.6 in the R group, with 20% reduced the risk of death/progression for pts receiving RP maintenance (HR 0.81, p=0.07; Figure 1). A subgroup analysis was performed to determine the consistency of RP vs R treatment effect in different subgroups using interaction terms between treatment and cytogenetic abnormalities, ISS, age, sex, induction treatment and response before maintenance (Figure 1). No difference in OS was observed (HR 1.02, p=0.93) but the OS analysis was limited by the low number of events. Median duration of maintenance was 23.0 months in RP pts and 20.5 months in R pts, 14% and 13% of pts discontinued due to AEs, in RP and R groups, respectively. Conclusion : This phase III trial compared 2 different Lenalidomide-containing induction regimens and 2 different Lenalidomide-containing maintenance regimens in an elderly community-based NDMM population. MPR prolonged PFS by approximately 5 months, yet the higher incidence of hematologic toxicity should be carefully considered. The addition of low-dose prednisone to standard lenalidomide maintenance reduced the risk of death/progression by 20%, with a good safety profile. Updated results will be presented at the meeting.

Abstract Background High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). The introduction of novel agents challenged the role of ASCT at diagnosis. We conducted a multicenter 2X2 randomized trial comparing conventional chemotherapy plus lenalidomide with ASCT followed by maintenance with lenalidomide-prednisone (RP) or lenalidomide (R) alone in newly diagnosed young MM (NDMM) patients. Methods Eligible patients with NDMM ≤ 65 years were enrolled. All patients received Rd induction (four 28-day cycles of lenalidomide 25 mg day 1–21 and low-dose dexamethasone 40 mg day 1,8,15,22) followed by stem cell mobilization. Patients were randomized to receive consolidation with CRD [six 28-day cycles of cyclophosphamide (300 mg/m2 day 1,8,15), dexamethasone (40 mg days 1,8,15,22) and lenalidomide (25 mg days 1–21)] or MEL200-ASCT (melphalan 200 mg/m2 with stem-cell support). Patients were randomly assigned to receive subsequent maintenance with RP (28-day cycles of lenalidomide 25 mg days 1–21 plus prednisone 50 mg every other day) or R alone (28-day cycles of lenalidomide 25 mg days 1–21). Primary study endpoint was progression-free survival (PFS); secondary endpoints included safety, responses and overall survival (OS). Data cut off was May 30th, 2013. Results Three-hundred and eighty-nine patients were enrolled in the trial. Patient characteristics were well balanced between CRD (n=194) and MEL200-ASCT (n=195), and between R (n=195) and RP (n=194) arms. Median follow-up was 31 months. In the intent to treat (ITT) analysis, the median PFS was not reached with MEL200-ASCT and 28 months with CRD (the respective 3-year PFS was 60% vs. 38%, HR=0.62, 95%CI: 0.49-0.85, P=0.003). Median time from enrolment to maintenance was 14 months. In the population of patients eligible for maintenance, 2-year PFS from the start of maintenance was 73% for RP and 56% for R patients (HR= 0.57, 95%CI: 0.34-0.93; P=0.03). In the subgroup of patients who received MEL200-ASCT, 2-year PFS from the start of maintenance was 83% for patients who received RP and 64% for those who received R alone (HR=0.36 95%CI: 0.15-0.87, P=0.02). In the subgroup of patients who received CRD, 2-year PFS from the start of maintenance was 64% for patients who received RP and 47% for those who received R alone (HR=0.75, 95%CI: 0.40-1.39, P=0.36). At present, no differences in OS were noticed between patients randomised to received CRD or MEL200-ASCT, and between patients who received RP or R maintenance. As expected, the rates of grade 3-4 hematologic (85% vs. 26%, P<0.001) and non-hematologic (35% vs. 19%, P=0.003) adverse events (AEs) were higher in the MEL200-ASCT arm compared with the CRD arm. The main non-hematologic AEs were infections (18% vs. 5%, P=0.001) and gastrointestinal AEs (18% vs. 3%, P<0.001). Rates of grade 3-4 hematologic (8% vs. 7%, P=0.85) and non-hematologic (12% vs. 13%, P=0.88). AEs were similar in the RP and R arms. The main non-hematologic AEs in both RP and R groups were infections (3% vs. 3%). At present, 6 second primary malignancies and 3 cases of cutaneous basalioma have been reported. Conclusions MEL200-ASCT significantly prolonged PFS in comparison with CRD. At present no difference in OS was reported, this may be due to the low number of events and to the length of follow-up. The increase in toxicity with MEL200-ASCT did not adversely impact on efficacy. The addition of prednisone to lenalidomide maintenance significantly reduced the risk of progression in comparison with lenalidomide alone, without increasing the toxicity. Updated data with longer follow-up will be presented at the meeting.

Abstract Abstract 1940 The combination of Melphalan-Prednisone-Lenalidomide (MPR) has shown promising results in elderly newly diagnosed myeloma patients. In the transplant setting, low-dose chemotherapy (induction) precedes high-dose chemotherapy (autologous transplantation consolidation). This approach reduces tumor mass, with few side effects, before achieving the maximum cyto-reduction with autologous transplantation. The same approach has been designed for the elderly patients. Accordingly induction with lenalidomide plus corticosteroids precedes consolidation with MPR. A two-stage phase II clinical trial was planned to evaluate the safety and efficacy of Lenalidomide-Prednisone (RP) as induction, followed by Melphalan-Prednisone-Lenalidomide (MPR) as consolidation and Lenalidomide as maintenance in elderly myeloma patients. Unfit patients with newly diagnosed symptomatic myeloma older than 65 years were enrolled. No exclusion criteria were included in the protocol, to avoid the selection of fit elderly subjects only. Patients with low blood count, abnormal performance status, hepatic, renal, cardiac or pulmonary functions were enrolled. Patients received 4 RP courses (Lenalidomide 25 mg/day for 21 days every 4 weeks, plus Prednisone 50 mg three times/week for 4 weeks) followed by 6 MPR cycles (Melphalan 2 mg and Prednisone 50 mg three times/week, for 4 weeks plus Lenalidomide 10–15 mg/day for 21 days every 4 weeks) and maintenance with Lenalidomide alone (10 mg/day for 21 days every 4 weeks). Two different dose-levels of Lenalidomide were tested in combination with MP: 15 mg (dose-level 1) and 10 mg (dose-level 2). Each cohort included 12 patients, with additional 22 patients enrolled at dose-level 2. Patients were evaluated for efficacy and toxicity after completion of at least 2 MPR cycles. Forty-six patients (median age 75, range 65–88) were enrolled. Thirty-six patients were evaluable after a median of 7 cycles and a median follow-up of 8.5 months. During RP induction, the most frequent grade 3–4 hematological adverse events were neutropenia (19%), anemia (11 %), thrombocytopenia (6%). During MPR consolidation, grade 3–4 adverse events were neutropenia (45%), and thrombocytopenia (3%). Neutropenia was increased by the addition of melphalan, but both thrombocytopenia and anemia were reduced. Non-hematological toxicities were more frequent during RP cycles and reduced during MPR cycles (cutaneous rash and infections). After RP induction, at least partial response (PR) rate was 67%, at least very good partial response (VGPR) was 17%. After 2 MPR cycles, PR rate increase to 72%, including 22% of patients who achieved at least a VGPR. Conclusions. Induction with RP followed by consolidation with MPR showed a manageable safety profile and reduced the risk of anemia, thrombocytopenia and non-hematological toxicity in unfit elderly myeloma patients. These data will be updated at the meeting.

Abstract Abstract 478 Background: The US community-based, phase 3b randomized, open-label, multicenter UPFRONT trial compares the efficacy and safety of three bortezomib (VELCADE®, Vc)-based regimens, VcD (Vc-dexamethasone), VcTD (Vc-thalidomide-dexamethasone), and VcMP (Vc-melphalan-prednisone), followed by weekly Vc maintenance, in elderly, newly diagnosed, transplant-ineligible multiple myeloma (MM) patients. This is the first phase 3 study of VcD and VcTD in this patient population. Methods: Patients with symptomatic, measurable MM were randomized (1:1:1) to receive 49 weeks of therapy: 24 weeks (eight 21-day cycles) of induction with VcD, VcTD, or VcMP (VcD: Vc 1.3 mg/m2, days 1, 4, 8, 11; D 20 mg, days 1, 2, 4, 5, 8, 9, 11, 12 [cycles 1–4]), days 1, 2, 4, 5 [cycles 5–8]); VcTD: Vc as before; T 100 mg/day, days 1–21; D as before); VcMP: Vc as before; M 9 mg/m2 and P 60 mg/m2, days 1–4, every other cycle), followed by 25 weeks (five 35-day cycles) of maintenance with weekly Vc 1.6 mg/m2, days 1, 8, 15, 22. Patients in the VcTD arm received concomitant prophylaxis with aspirin, full-dose warfarin, or low-molecular weight heparin unless medically contraindicated. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall response rate (ORR), complete response (CR)/near CR (nCR) and very good partial response (VGPR) rates, overall survival (OS), and safety. Best confirmed responses were assessed by investigators per modified International Myeloma Working Group (IMWG) criteria. Adverse events (AEs) were graded by NCI-CTCAE v3.0. PFS and OS were estimated by Kaplan–Meier methodology. For the first time, we report results from the entire cohort of 502 randomized patients (VcD, n=168; VcTD, n=167; VcMP, n=167), who completed up to a maximum of 13 cycles of treatment. Results: Patients in the VcD, VcTD, and VcMP arms had a median age of 74.5, 73.0, and 72.0 years, respectively, and 71%, 62%, and 72% had ISS stage II/III disease. Patients received a median of 8 (VcD), 6 (VcTD), and 7 (VcMP) treatment cycles; 50%, 38%, and 42% of patients, respectively, received Vc maintenance. Response and safety data are summarized in the table. All three Vc-based induction regimens exhibited substantial activity, with ORR of 73% (VcD), 80% (VcTD), and 69% (VcMP) during the treatment period. After a median follow-up of 21.8 months, no significant difference in PFS was observed between the treatment arms; median PFS was 13.8 months (VcD), 14.7 months (VcTD), and 17.3 months (VcMP), respectively (Figure). 1-year OS estimates were 87.4% (VcD), 86.1% (VcTD), and 88.9% (VcMP). Rates of grade ≥3 AEs, serious AEs (SAEs), and discontinuations due to AEs during the treatment period were highest for the VcTD arm. The most common grade ≥3 AEs across all three arms during the treatment period were neuropathy peripheral (23%), fatigue (10%), and diarrhea (9%). Grade ≥3 pneumonia was reported in 10% (VcD), 6% (VcTD), and 6% (VcMP) of patients. AEs of deep vein thrombosis/pulmonary embolism were reported in 8% (VcD), 7% (VcTD), and 2% (VcMP) of patients. Compared with rates during induction, Vc maintenance produced little additional toxicity; across all three treatment arms, only 5% of patients experienced grade ≥3 peripheral neuropathy during cycles 9–13. One second primary malignancy (lung neoplasm) was reported in the VcMP arm. Conclusions: VcD, VcTD, and VcMP induction followed by weekly Vc maintenance produced similar activity in elderly, newly diagnosed, transplant-ineligible MM patients. Patients in the VcD doublet arm appear to have similar long-term outcomes to patients in the VcTD and VcMP triplet arms.

Background: Maintenance therapy with lenalidomide post-autologous stem cell transplantation (ASCT) has shown to improve progression-free survival (PFS) in multiple myeloma (MM), and has largely become the standard of care. However, toxicity leads to early discontinuation in nearly one-third of patients and additional options are needed (McCarthy, et al, JCO, 2017). Ixazomib is another maintenance option that has been shown to improve PFS; however, studies comparing lenalidomide and ixazomib are lacking. In this randomized phase 2 study, we analyzed the safety and efficacy of using lenalidomide and ixazomib as part of consolidation and maintenance therapies after ASCT (NCT02253316). Methods: Eligible patients, age 18-70 with newly diagnosed MM undergoing ASCT during first-line treatment, were consented prior to ASCT. Approximately 4 months following ASCT, patients received 4 cycles of consolidation therapy with IRd [ixazomib 4 mg on days 1, 8 and 15 of a 28-day cycle, lenalidomide 15 mg on days 1 through 21, and dexamethasone 40 mg on days 1, 8 and 15]. Primary data on IRd consolidation were presented at ASH 2018 (Abstract 109920). One month after the last consolidation cycle, patients were randomized (1:1) to maintenance therapy with single-agent ixazomib (4 mg on days 1, 8 and 15 of a 28-day cycle) or lenalidomide (10 mg daily months 1-3 followed by 15 mg for months 4+). The arms were stratified based on MRD-status post-consolidation. In total, 237 patients were enrolled from 10 US centers. This abstract coincides with planned interim analysis 3 which is the first comparison of ixazomib and lenalidomide maintenance. While the study was not powered to compare PFS between the two arms, the sample will provide a reasonable power to estimate non-inferiority. There is a planned stopping rule for non-inferiority set at a hazard ratio of &gt;1.3 in favor of lenalidomide. Secondary end-points include MRD-negativity following 12 cycles and toxicity. Results: At time of abstract submission, 215 patients had completed IRd consolidation and 191 had begun maintenance. 90 were randomized to ixazomib and 94 to lenalidomide. 7 patients were not randomized due to toxicity during consolidation; data from these patients are not included in the analyses. The characteristics of the two arms are summarized in Table 1. Hematologic toxicity has been infrequent with ixazomib with neutropenia and thrombocytopenia occurring in 11% and 23% of patients. In comparison, neutropenia and thrombocytopenia occurred in 45% and 35% of patients on lenalidomide. The most common non-hematologic toxicities in both arms have been GI-related and infections, both expected events. 16% of patients on ixazomib have experienced Grade 3-4 non-hematologic toxicity compared to 34% on lenalidomide. No grade 3 or higher peripheral neuropathy has been reported in either arm. 11% of patients on ixazomib have discontinued due to toxicity and another 9% have required a dose reduction to 3mg. Lenalidomide toxicity has led to discontinuation in 15% of patients and another 12% were dose reduced to 5mg. Only 45% of patients receiving 4+ cycles of lenalidomide were able to titrate to the 15mg dose. After a median follow-up of 11.2 months from randomization (19.7 months post-ASCT), 30% of patients on ixazomib have discontinued treatment due to disease progression. After a median follow-up of 12.3 months from randomization (20.2 months post-ASCT), 18% patients on lenalidomide have discontinued treatment due to disease progression. Conclusion: Ixazomib and lenalidomide maintenance have been well tolerated to date. A comparison of PFS is currently being conducted as part of interim analysis 3 and final results will be presented, representing the first report directly comparing lenalidomide and ixazomib maintenance.

Abstract Abstract 3964 Background: Bortezomib in combination with dexamethsone is administered twice a week for 2 weeks with excellent therapeutic outcome. However, in a proportion of patients it is associated with toxicities such as neuropathy and twice a week regimen is inconvenient especially in older patients. To improve convenience and compliance, we have investigated the efficacy and safety of a weekly bortezomib regimen. Methods: We conducted a phase II multi-center single-arm study in participating Veterans Hospitals (VA) nationwide evaluating bortezomib administered at 1.6 mg/m2 IV weekly for 4 weeks with 1 week off with dexamethasone 40mg PO on the day of and day after bortezomib for upto 6 cycles in newly diagnosed multiple myeloma patients not considered for autologous stem cell transplant. The objective is to evaluate overall response rate (ORR) and toxicity of this regimen. Results: We have enrolled all planned 50 patients (median age-71; range 50–89) at 12 VA Hospitals. Patients had significant co-morbidities including 86% with cardiovascular problems, 67% with diabetes and/or hyperlipidemia, 54% with renal dysfunction, 37% with respiratory problems, and 18% with history of cancer. All patients were on at least 5 daily medications. Of the 50 patients enrolled, 42 patients have received at least 1 cycle of therapy and were evaluable for toxicity and efficacy. With a median of 4 cycles administered, this regimen was very well tolerated. Ten patients experienced neuropathy: 6 patients experienced grade 1, two patients developed grade 2 neuropathy, while two patients who had grade 1 neuropathy at diagnosis increased to grade 2 neuropathy with pain, and the other patient increased to grade 3 neuropathy with pain, with an overall Grade 3 neuropathy rate of 2.4%.Dexamethasone dose was reduced in 30% while bortezomib dose was reduced in 10% of the patients. Additionally, grade ≥1 asthenia was observed in 52%, constipation in 38%, diarrhea in 34%, anemia in 64%, vomiting/nausea in 26%, and thrombocytopenia in 54%. Four patients have died of co-morbidities which were considered unrelated or probably unrelated to the treatment with bortezomib. Of the patients who received at least 1 cycle of therapy, 62% patients achieved ≥PR; 12% CR/nCR and an additional 14% achieved VGPR. Including MR in the analysis, ORR was observed in 90% of the evaluable patients. On intent to treat analysis including all 50 patients, ORR was observed in 76% patients and ≥ PR in 52% patients. Conclusions: Once a week bortezomib with dexamethasone regimen is effective and well tolerated even in older patients with significant co-morbidities and should be considered as an important option in multiple myeloma.

INTRODUCTION. The proteasome inhibitor (PI) Ixazomib, approved for the treatment of relapsed/refractory multiple myeloma (MM), represents an appealing option for the management of elderly patients, due to its oral administration and the lack of peripheral neuropathy. We previously presented preliminary results of the phase II EMN10-Unito study investigating Ixazomib in combination with dexamethasone (Id), Cyclophosphamide-dexamethasone (ICd), Thalidomide-dexamethasone (ITd) or Bendamustine-dexamethasone (IBd) as induction therapy followed by single-agent Ixazomib maintenance in transplant-ineligible newly diagnosed (ND) MM patients. Here we present updated results of the study with a longer follow-up. METHODS. Transplant-ineligible NDMM patients ≥65 years were enrolled. Treatment consisted of 9 28-day induction cycles of Ixazomib 4 mg on days 1,8,15 and dexamethasone 40 mg on days 1,8,15,22 or Id plus either Cyclophosphamide 300 mg/m2 orally on days 1,8,15 or Thalidomide 100 mg/day or Bendamustine 75 mg/m2 iv on days 1,8; followed by Ixazomib maintenance (4 mg on days 1,8,15) for up to 2 years. The primary endpoint was the selection of the most effective induction regimen considering a 2-year progression-free survival (PFS) ≥65% as satisfactory; secondary endpoints were very good partial response (VGPR), PFS2, overall survival (OS) and adverse events (AEs) during induction and maintenance. RESULTS. 171 patients (Id 41, ICd 59, ITd 60 and IBd 11) with a median age of 74 years were enrolled and started treatment. Two of the four investigational arms were prematurely closed due to low-enrollment (IBd arm, 11 patients enrolled) and high risk of inefficacy (Id, 41 patients enrolled). Median follow-up was 27 months. After the induction phase, ICd and ITd resulted in higher ≥ PR (75%-84% vs. 57%; p&lt;0.05) and VGPR (46%-48% vs 24%; p&lt;0.05) rates as compared to Id. The median PFS was 10.3 months with Id, 17.9 with ICd, 12.3 with ITd, and 13.8 with IBd, with a 2-year PFS probability of 31%, 39%, 27% and 40%, respectively. Median OS was not reached in either arm, without significant differences in the 2-year OS across arms (Id: 85%; ICd: 75%; ITd: 78%; IBd: 89%). Grade 3-4 non-hematological AEs were more frequent in the ITd arm (45%) as compared to the Id (17%), ICd (17%) and IBd (36%) arms, as well as the risk of treatment discontinuation due to AEs: ITd 17% vs Id 10%, ICd 12%, IBd 9%. Overall, 102 patients (60%) completed the induction phase and proceeded to ixazomib maintenance (median follow-up from start of maintenance: 18 months). The best response during maintenance was PR in 26%, VGPR in 29%, and complete response (CR) in 26% of patients; 18% of patients improved the response obtained during induction by at least one IMWG category. The median PFS from start of maintenance was 15 months. The median duration of maintenance was 12 months. All grades AEs occurred in 39% of patients during maintenance, while grade 3-4 AEs occurred in 10% of patients. Grade 1-2 peripheral neuropathy (PN) was reported in 15% of patients, without grade 3-4 events. Overall, 15% required at least one dose reduction of ixazomib and 12% discontinued ixazomib maintenance due to AEs. CONCLUSIONS. Safety and efficacy data suggest that Id combined with cyclophosphamide was the most promising induction strategy compared to the other investigated combinations. Continuous treatment with single-agent Ixazomib confirmed its efficacy and tolerability in elderly NDMM patients.

Abstract Background High-dose chemotherapy (HDT) with autologous stem cell transplant improves outcome of multiple myeloma (MM) patients in comparison to conventional chemotherapy. The incorporation of new drugs into induction, consolidation and maintenance therapy is changing the treatment paradigm and is questioning the role of HDT in newly diagnosed MM (NDMM) patients <65 years. Previous finding have been presented (Boccadoro, ASCO 2013) and this analysis provides a longer follow-up. Aims To compare in a prospective randomized trial melphalan-prednisone-lenalidomide (MPR) with tandem melphalan (200 mg/m2) (MEL200) both followed by maintenance with lenalidomide or no maintenance in NDMM patients. Methods A 2x2 factorial randomized trial was designed. The induction treatment consisted of four 28-day cycles of lenalidomide (25 mg d 1-21) and low-dose dexamethasone (40 mg d 1,8,15,22) (Rd). As consolidation, patients were randomized to MPR (N=202) [six 28-day cycles of melphalan (0.18 mg/k g d 1-4), prednisone (2 mg/kg d 1-4) and lenalidomide (10 mg d 1-21)] or MEL200 (N=200)[tandem melphalan 200 mg/m2 with stem-cell support]. Patients were further randomized, within each group, to receive lenalidomide maintenance (10 mg, days 1-21, N=198) or no maintenance (N=204). Primary study endpoint was progression free survival (PFS). The secondary study endpoints included response rates, safety and overall survival (OS). Data were analyzed in the intent-to-treat (ITT) population. Results From November 2007 to July 2009, 402 patients with NDMM <65 years of age were enrolled. All patients were stratified according to International Staging System (ISS) and age. Patient characteristics were well balanced in all groups. In the MPR group, the Very Good Partial Response (VGPR) rate was 50% with 13% of Complete Response (CR) while the VGPR rate was 52% including 19% of CR in the MEL200 group. In the MPR group the CR rate improved from 13% after consolidation to 17% after maintenance. In the MEL200 group the CR rate improved from 19% after consolidation to 25% after maintenance. After a median follow-up of 48 months, the median PFS was 24.2 months in MPR group and 38.6 months in MEL200 group ( P< 0.0001). A multivariate analysis confirms the PFS benefit associated with MEL200 across all subgroups of patients defined by stratification factors and baseline characteristics. The 5-year OS rate was similar between MPR (62%) and MEL200 (71%; P= 0.27). In a landmark analysis, lenalidomide maintenance significantly extended PFS from the start of maintenance (median 42,7 months) compared with no maintenance (median 17.5 months; P<.0001). The 4-year OS rate from the start of maintenance was higher in patients who received lenalidomide maintenance (80%) compared with patients who did not (62%; P= 0,01). No significant interaction was detected between MPR/MEL200 (P=0.704) and maintenance/observation (P=0.984) effects. During consolidation, the incidence of grade 3-4 adverse events (AEs) between MPR and MEL200 were as follow: neutropenia (50% vs. 90%), thrombocytopenia (8% vs. 89%), infections (1% vs. 15%) and gastrointestinal (0% vs. 18%), with complications being higher with MEL200. During the maintenance phase, grade 3-4 hematologic AEs were reported in 17% of patients receiving lenalidomide (16% neutropenia). For individual group comparisons during maintenance, grade 3-4 hematologic AEs were observed in 20% of patients receiving MPR plus lenalidomide maintenance compared with 15% receiving MEL200 plus lenalidomide maintenance. Second primary malignancies were observed in 11 patients (3%), and were mainly solid tumors. Four solid tumors were observed in the MEL200 group and one in the MPR group in the maintenance arm, while three solid tumors were observed in the MEL200 group and three in the MPR group in no maintenance arm. Conclusion The administration of MPR was significantly inferior to MEL200 in terms of PFS. Toxicities were significantly higher in MEL200 group, but manageable. OS is similar between MPR and MEL200. Lenalidomide maintenance significantly reduced the risk of progression and of death independently from the previous treatment.

Abstract INTRODUCTION The outcome of patients with Multiple Myeloma (MM) improved considerably over the last years due to an increase in availability of novel agents. However, the optimal sequence is largely unknown. Besides efficacy, determination of the optimal sequence is also of importance in light of cost effectiveness. To this end the development of a health economic (HE) model would be of interest. For such a model time to next treatment (TTNT) is required. We previously showed that in stem cell transplant (SCT) eligible patients TTNT was not treatment but response (i.e. complete, partial or no response; CR, PR or NR) dependent. We here investigate whether response was predictive for TTNT independent of the treatment regimen in SCT ineligible patients (pts) with MM. METHODS We analyzed patient level data of two phase 3 randomized controlled trials (RCTs) performed by the Dutch-Belgian cooperative HOVON group in newly diagnosed, transplant-ineligible patients. The HOVON-87 (N=668) compared Melphalan Prednisone (MP) with Thalidomide followed by Thalidomide maintenance (MPT-T) versus MP with Lenalidomide followed by Lenalidomide maintenance (MPR-R) (Zweegman et al Blood 2016) (EudraCT number 2007-004007-34). The HOVON-49 (N=333) compared MP versus MPT (including Thalidomide maintenance) (Wijermans et al J Clin Oncol 2010) (ISRCTN 90692740). The following data were included: treatment, best response, TTNT and survival status. Pts were censored after last date of contact. Pts who did not have information on TTNT and/or response were excluded from our analyses. Kaplan-Meier curves and Cox proportional hazards models were fitted on this data to investigate whether the TTNT is mainly response dependent and whether the quality of response is predictive for TTNT. RESULTS We included 519 HOVON-87 pts and 252 HOVON-49 pts. First, we analyzed the TTNT hazard ratios (HRs) of the active and comparative arm within each response category for both trials. The TTNT HR of the HOVON-87 pts with a CR (N=75) was not significantly different between treatments (HR 1.340, 95% CI: 0.590-3.039, p-val = 0.484). We also found no significant difference in PR pts (HR 0.952, 95% CI: 0.753-1.204, p-val = 0.681, N = 375) and NR pts (HR: 0.898, 95% CI: 0.518-1.556, p-val = 0.701, N=69). The number of CR pts in the HOVON-49 study was too low (N=8) to allow for a reliable analysis of this response category. Therefore, for this study we present very good PR (VGPR) as separate category. For both VGPR (N=44 pts) and PR pts (N=95 pts) we did see a significant difference in TTNT in the treatment arms (HR: 0.363, 95% CI: 0.174-0.757, p-val = 0.007 and HR:0.634, 95% CI: 0.417-0.965, p-val = 0.033 respectively). However, for NR pts the TTNT HR was similar (HR: 1.131, 95% CI: 0.746-1.714, p-val = 0.561, N=105 pts) Second, we compared the TTNT between the different response groups within each trial. For HOVON-87, the median TTNT for CR pts was 63.4 months (mos) (95% CI: 51.8 mos - not evaluable), for PR pts it was 24.6 mos (95% CI: 22.8 - 27.3 mos), and for NR pts it was 19.5 mos (95% CI: 9.7 - 25.3 mos). The TTNT of CR pts was significantly longer than of PR pts (HR: 3.923, 95% CI: 2.601-5.917, p-val = 0.000). And the TTNT of PR pts was significantly longer than of NR pts (HR: 1.411, 95% CI: 1.052-1.893, p-val - 0.000). For HOVON-49, the median TTNT for VGPR pts is 23.4 mos (95% CI: 15.0 - 26.7 mos), PR pts was 19.0 mos (95% CI: 15.4 - 21.5 mos), and for NR pts was 3.7 mos (95% CI: 3.4 - 4.3 mos). Only the TTNT of PR pts was significantly longer than the TTNT of NR pts (HR: 3.978, 95% CI: 2.938 - 5.388). CONCLUSIONS Data from the HOVON-87 showed a relationship between response and TTNT. Pts in this trial achieving a CR were observed to have a significantly longer TTNT compared to those achieving PR at best. Furthermore, TTNT was not significantly different for the treatment arms (e.g. patients with CR after MPR-R had similar TTNT than patients with CR after MPT-T). Establishing a relationship between response and TTNT was challenging among pts from the HOVON-49 since i) too few CR pts were seen in this trial and ii) the experimental arm included maintenance while the comparator treatment did not. We can conclude that the previous established relationship between response and TTNT was partly confirmed for newly diagnosed SCT ineligible MM pts. Further research is necessary to identify other relevant predictors for TTNT and to confirm the current findings before we can incorporate this into our HE model.

Abstract Background: Despite advances in novel myeloma treatments and autologous hematopoietic stem cell transplantation (ASCT), allogeneic HSCT (alloSCT) remains the only curative option for patients (pts) with multiple myeloma (MM). Questions remain as to the timing of alloSCT, toxicity risks and optimal conditioning regimen. The addition of bortezomib (Vel) to fludarabine (Flu) and melphalan (Mel) for conditioning prior to alloSCT is based on the demonstrated safety of Vel in combination with melphalan prior to ASCT, the synergistic effect of Vel with Mel, and the ability of Vel to selectively eliminate allo-reactive T-cells. Methods: We present a prospective Phase II study using Flu/Mel/Vel (FMV) as a conditioning regimen for alloSCT. The primary endpoint is overall survival (OS), and secondary endpoints include progression free survival (PFS), incidence of graft-versus-host disease (GVHD) and transplant related mortality (TRM). For related donors, the conditioning regimen was Flu 30 mg/m2 days -5, -4, -3, -2, Vel 1.6 mg/m2 days -4, -1, Mel 140 mg/m2 day -2. For unrelated donors, rabbit ATG 4 mg/kg was given in divided doses days -3, -2, -1. GVHD prophylaxis consisted of methotrexate and tacrolimus. We compared pts receiving FMV to historical controls of pts receiving FM at the same dose and schedule without Vel. We also compared pts receiving FMV to all pts with MM treated with alloSCT including all regimens and donor types. The response criteria from the IMWG and M-Smart criteria were used to determine response and risk, respectively. Chi-square tests of association and Wilcoxon rank sum tests were performed to test for differences across groups. OS/PFS probabilities were calculated using the Kaplan-Meier product limit estimator with log rank-tests. Multivariate Cox proportional hazard models examined factors associated with OS/PFS. Results: Of the 54 pts who received FMV, 35 (65%) were male and the median age was 56 years. Twenty-seven pts had an HLA matched sibling donor and 27 had an unrelated donor. At the time of alloSCT, 5 pts were in a CR, 27 in a VGPR, 13 in a PR, 9 had < PR. Twenty eight pts (52%) had high risk disease. Twenty-nine pts (53%) received alloSCT as salvage, defined as relapsed or refractory to ASCT, and 25 pts (46%) as consolidation after ASCT. OS was 42% at 10 years. While 32 pts developed aGVHD, only 2 had ≥ Grade 3. Of the 31 pts who developed cGVHD, 23 were graded as extensive. TRM was 5% at day 100, and 15% over 10 years. Pts in the control groups had similar baseline characteristics to the FMV group. The only significant difference was 47 pts (72%) who received FM were transplanted as salvage, and 18 (28%) as consolidation after ASCT (p=0.035). The total number of pts who did not receive FMV (non FMV) was 121, with 66 pts receiving FM. Compared to pts who received FMV, there was no difference in OS for pts who received FM or the non FMV group, 35% (p=0.55) and 48% (p=0.855) respectively. There was no difference in pts who developed aGVHD, however 9 pts (13%) had ≥ grade 3 aGVHD in the FM group (p=0.004) and 15 (12%) in the non FMV group (p=0.006). The cumulative incidence of cGVHD was similar with 51% for pts receiving FM and 60% for FMV pts (p=0.32). TRM was similar to pts who had received FMV; 18% for FM and 17% for non FMV. There were no differences between the 3 groups across disease risk, donor type, or disease status at the time of alloSCT. Multivariate analysis of the 3 groups, shows achieving a CR after alloSCT (p=0.0006) or having cGVHD (p=0.0004) predicts for improved OS, while severe aGVHD (p=0.0002) predicts for decreased OS. Discussion: While FMV was associated with a lower incidence of severe aGVHD, the addition of bortezomib to the FM backbone did not improve PFS or OS. Day 100 TRM was low for all regimens, and the addition of Vel did not impact overall TRM. For all 175 pts, those who achieve a CR after alloSCT had a significantly improved OS. This prompts the question of whether strategies should be employed post alloSCT to maximize response to a CR, and the role of achieving MRD negativity after alloSCT also needs to be elucidated.
