Dose Escalation Phase 2 Trial of Carfilzomib Combined with Thalidomide and Low-Dose Dexamethason in Newly Diagnosed, Transplant Eligible Patients with Multiple Myeloma. a Trial of the European Myeloma Network

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 Introduction While high dose chemotherapy and autologous hematopoietic stem cell transplantation (auto-HCT) is an accepted part of up front therapy for patients with multiple myeloma (MM), the role of this treatment modality for relapsed patients is still evolving. In the era of modern therapeutics, it is reasonable to consider that the advantages gained for relapsed patients in the conventional setting may also extend to auto-HCT. We thus hypothesized that lenalidomide could be safely combined with high dose melphalan in the salvage auto-HCT setting and yield a meaningful duration of disease control. Methods We conducted a phase I/II study of lenalidomide and high dose melphalan + auto-HCT. MM patients with relapsed or progressive disease were treated with 7 days of oral lenalidomide (doses of 25, 50, 75 or 100 mg daily for the 7 days) on days (-8) to (-2). High dose melphalan (total of 200 mg/m2) was administered as 100 mg/m2 IV on days (-3) and (-2) followed by auto-HCT on day 0. The Eff-Tox method of Thall, Cook, and Estey was used for dose escalation with cohorts of 3 to maximize the trade-off between efficacy and toxicity, defined as CR at day 90 and regimen-related death, graft failure, or select grade 3+ events within 30 days after transplant, respectively. Kaplan-Meier curves were used to estimate PFS and OS and the log-rank test was used to assess univariate differences between dose levels. Bayesian logistic regression and survival time models were used for multivariable analyses, with posterior probabilities greater than 0.95 or less than 0.05 considered significant. Results 57 patients were enrolled, of which 18 (32%) had received a prior auto-HCT. A total of 3, 5, 24 and 25 patients received 25, 50, 75 and 100 mg of lenalidomide, respectively. Median age at auto-HCT was 60 (34-72) years. Median prior lines of treatment were 3 (1-11). Twenty-two patients (39%) were lenalidomide-refractory at study entry. Patient characteristics did not differ significantly between the lenalidomide dose levels. In total, only 2 dose limiting toxicities were seen, both at dose level 75mg. Two patients died of nonrelapse causes (viral infection 1, cardiac failure 1) for a treatment-related mortality of 3%. Median time to both neutrophil and platelet engraftment was 11 days. One patient developed a second primary malignancy (squamous cell cancer of the skin). By day +90, 8 patients (14%) had achieved a CR, 25 (44%) a CR or very good partial response (VGPR), and 42 (74%) a CR, VGPR or partial response (PR), with no significant differences in response rates among the 4 lenalidomide dose levels. By day 180, 12 patients (21%) had achieved a CR. Multivariable Bayesian logistic regression revealed that high-risk cytogenetics, bone marrow disease burden and number of prior lines of treatment were each significantly associated with a lower probability of reaching CR by day 90. With a median follow up of 12.3 months (range 0.5-41), median PFS was 23.7 months and median OS had not yet been reached. The 1-year progression-free rate was 64% (95% CI: 49-75%). Multivariable Bayesian survival time models found both dose level and longer time between diagnosis and transplant to be significantly beneficial to both OS and PFS. In addition, high risk cytogenetics and LDH were significantly harmful to OS, and LDH was moderately harmful for PFS as well (Figures 1 and 2). Conclusion: Lenalidomide up to 100 mg PO daily x 7 can be safely combined with high dose melphalan and auto-HCT. Our previous data has shown a median PFS of 12.3 months in a comparable population. Thus this treatment regimen yields an encouraging PFS, offering relapsed or refractory patients another option for disease control. Figure 1.

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 Abstract 633 Introduction: This independent phase 2 trial was designed to evaluate carfilzomib (C) combined with thalidomide and dexamethasone during induction and consolidation for feasibility, response and progression-free survival (PFS) in patients with newly diagnosed symptomatic MM, who were candidates for high-dose therapy. Patients with symptomatic MM and measurable disease, age 15 to 65 and no significant co-morbidity were eligible. At diagnosis Fluorescent in situ Hybridization (FISH) was performed of recurrent translocations, trisomy 9, del(17p), del (13q) and add(1q) Patients received 4 cycles of carfilzomib at 20 mg/m2 on days 1 & 2 followed by 27mg/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, thalidomide 200 mg days 1 – 28 of a 28 day cycle and dexamethasone 40 mg days 1, 8, 15 & 22 of a 28 day cycle. Stem cell harvest was performed with cyclophosphamide 2 g/m2 and G-CSF. Following HDM (200 mg/m2) and autologous stem cell transplantation (ASCT), consolidation therapy consisted of 4 cycles of carfilzomib 27 mg/m2 days 1, 2, 8, 9, 15 & 16 of a 28 day cycle, thalidomide 50 mg days 1–28 of a 28 day cycle and dexamethasone 20 mg days 1, 8, 15, 22 of a 28 day cycle. The primary endpoint was response, other endpoints were complete response (CR) according to IMWG criteria, immunofixation-negative CR (sCR), VGPR all pre-and post HDM, PFS and overall survival (OS). An interim analysis was planned after 20 evaluable patients, primarily to guard against excessive toxicity and/or lack of response. Results: While recruitment is still ongoing, 34 patients have been included, of which the first 20 patients were are evaluated for response and toxicity, with a median follow-up of 5 months. One patient was excluded because unavailability of data. Median age was 60 yr and ISS stages I/II/III were 8/6/5, respectively. Four patients went off treatment because of intolerance to thalidomide (n=1), tumor lysis syndrome with renal failure (n=1) or respiratory infections (n=2). Adverse events CTC grade 3+4 included tumor lysis syndrome (n=2), metabolic disorders (n=4), cardiovascular including DVT (n=5), gastrointestinal (n=2), skin rash (n=2) and reversible renal failure (n=3). Peripheral polyneuropathy grades 1+ 2 was observed in 7 (35%) of patients, but no grade 3 or higher. Responses after cycle 1 were CR + sCR 5%, VGPR 32%, PR 47%, SD 10%, NE 5% and after induction overall CR + sCR 21%, VGPR 47%, PR 16%, SD 10%, NE 5%. Median time to maximum response was 1 cycle. Secondary analysis revealed that responses occurred across cytogenetic subgroups as determined by FISH, i.e. add (1q) (n=2), t(4;14) (n=2), del(17p) (n=1) and del(13q) (n=5). Stem cell harvest was accomplished with standard CD34+ yield in all patients and HDM/ASCT was performed with complete hematologic recovery in 4/4 patients. Conclusion: Carfilzomib combined with thalidomide and dexamethasone during induction and consolidation is feasible and effective. The complete data including response after consolidation will be reported at the ASH meeting. This EMN trial was registered as NTR2422. Carfilzomib and an unrestricted grant was provided by ONYX Pharmaceuticals.

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. This trial was registered at www.trialregister.nl as NTR 2528, EudraCT 2009-017903-28 This trial was supported by unrestricted grants from Celgene and Janssen.

Abstract Abstract 40 Introduction: This independent trial was designed to evaluate the efficacy of bortezomib (B) during induction and maintenance on progression-free survival (PFS) in patients with newly diagnosed symptomatic MM, who were candidates for high-dose therapy. Patients were randomly assigned to 3 cycles of standard VAD (arm A) or PAD (Arm B); PAD was dosed as B 1.3 mg/m2, days 1,4,8,11, doxorubicin 9 mg/m2, days 1–4, dexamethasone 40 mg, days 1–4, 9–12, 17–20). Patients received one (HOVON) or two (GMMG) high-dose melphalan (HDM) 200 mg/m2 with ASCT. Maintenance consisted of thalidomide (T) 50 mg daily (arm A) or B 1.3 mg/m2, 2-weekly (arm B) for 2 years. Primary endpoint was PFS, other endpoints were complete response (CR) (EBMT), immunofixation positive CR (nCR), VGPR pre-and post HDM and survival (OS). The protocol specified analysis was intention-to-treat and censored for patients who received allo-SCT after HDM1 (n=46). We report the analysis of the first 626 randomized patients. The final analysis of all patients will be presented at the meeting. Results: 13 patients were excluded (7 not eligible, 6 not evaluable). The two arms (A:n=305;B:n=308) were well balanced for age, Salmon/Durie stage II/III, renal failure (11%), and serum B2M. Medium follow-up is 40 months. 89% of patients completed induction and HDM1. In GMMG after HDM1 80% of patients received 2nd HDM. Full dose B could be administered in 82% of patients. Polyneuropathy (PNP) WHO gr 3+4 occurred in 7% (arm A) and 16% (arm B). 204 (67%, arm A) and 174 (57%, arm B) patients started maintenance. 64% of patients tolerated full dose B and 27% reduced dose. 47% of patients on B maintenance went off protocol because of toxicity (9%), progression (29%) or other (9%). In contrast 64 % on T maintenance went off protocol because of toxicity (31%), progression (31%) or other (2%). nCR/CR rates were 7/9% (arm A) vs 9/21% (arm B) at 3 months after HDM-1 and 12/26% (arm A) vs 12/38% (arm B) on protocol. ≥VGPR in arm-A vs arm-B were 40% vs 60% after HDM-1 and 61% vs 75% on protocol. PFS was superior in arm B (HR 0.81, p=0.047; adjusted for ISS: HR 0.81, p=0.056). PFS at 36 months was 42% (arm A) vs 46% (arm B). Multivariate Cox regression showed treatment arm (p=0.037), IgA (p=0.007), ISS stage (p=0.007), WHO Performance Status (p<0.0001), del13/13q- (p=0.015) and study group (2nd HDM) (p=0.015) as significant PFS variables. Patients treated with bortezomib had a better OS (HR 0.74, p=0.048), with study arm, WHO, IgA, ISS stage and del13/13q- as significant variables. Subgroup analysis of response at 12 months showed no impact on PFS and an impact of VGPR/nCR/CR on OS only in arm A. Adverse cytogenetic markers (p<0.05) in the combined group were 13q14, 17p-, t(4;14) for PFS and OS. Detailed FISH data are reported separately. The response and survival data of the subgroup analysis are given below. We conclude that B achieves high nCR/CR during induction, that B maintenance is well tolerated and is associated with additional responses. Bortezomib achieves superior PFS and results in an improvement of survival.

Severe Mucositis

Abstract Introduction: Severe mucositis in the autologous transplant setting has been correlated with adverse outcomes; longer febrile neutropenia duration, doubling of infectious risk, 2.7 additional days of total parenteral nutrition, 2.6 additional days of IV narcotics, increased length of stay (LOS), 3.9-fold increase in 100-day mortality, and US$25,405 increase in hospital charges (Sonis, JCO, 2001 19(8)). In a 40 patient randomized trial investigating cryotherapy (6 hours versus none) following high dose melphalan, grade 3/4 mucositis occurred in only 14% of patients using cryotherapy compared to 74% of patients using saline rinses (Lilleby, BMT, 2006 37). Prolonged cryotherapy is a significant hardship for patients and has resulted in nausea, vomiting, headache, toothache, and chills. We performed a randomized study investigating 2 versus 6 hours of cryotherapy in multiple myeloma (MM) patients undergoing autologous stem cell transplant (ASCT) with melphalan conditioning. Hypothesis: We hypothesized that a 2-hour cryotherapy regimen would be non-inferior to 6-hours in severity of mucositis, LOS, and incidence of bacteremia. Methods: We conducted a non-inferiority investigation of 146 sequential MM patients undergoing high dose melphalan with autologous stem cell rescue. Patients were consented and randomized to either 2 (n = 73) or 6 hours (n = 73) of cryotherapy via block randomization based on hemoglobin (less or greater than 11 g/dL), fat free mass (30-50, 50-70, >70 kg), or measured 24hr creatinine clearance (<30, 30-60, >60 mL/min). The cryotherapy process consisted of patients’ melting shaved ice inside their mouth for the designated period of time; flavoring with snow cone syrup was permitted. Inpatient nurse practitioners graded mucositis via WHO criteria. Patients received antifungal (fluconazole) and antiviral (acyclovir or valacyclovir) prophylaxis. Subset analyses investigated the incidence of bacteremia in all patients. Results: Median age was 59 years (range 35 - 72) and 60 (range 38 – 71), and the median measured creatinine clearance was 90.6 mL/min (range 0.2 – 168.7) and 85.4 mL/min (range 21.5 – 196.5) for the 2 hour and 6 hour groups respectively. Length of hospitalization (mean of 15 days) did not differ significantly between the 2 cohorts (p = 0.54). Mucositis was graded daily after melphalan infusion. In the 2-hour cohort, 59% of the patients had mucositis (31 patients with grade 1, 10 with grade 2, and 2 patients with grade 3). In the 6-hour cohort, 64% had mucositis (35 patients with grade 1, 9 with grade 2, and 3 patients with grade 3). These results suggest that 2-hour cryotherapy was not inferior to 6-hour therapy in decreasing mucositis grade. In the entire 146 patient group, approximately 30% developed a positive blood culture after transplant, including 25 (34%) and 20 (27%) in the 6-hour and 2-hour groups respectively. The three most common infectious organisms included gram negatives (n = 12 patients), polymicrobial (n = 7), and non-group A streptococcus (n = 7). In the cohort treated with 2-hour cryotherapy, positive blood cultures did not correlate with grade of mucositis (r = 0.05, p = 0.65). Conclusions: In MM patients undergoing ASCT, 2-hour cryotherapy did not increase mucositis compared to 6-hours. The incidence of blood stream infection was not different between groups. In addition, having an infection did not correlate with grade of mucositis.These results suggest that a 2-hour cryotherapy regimen is not inferior to a 6-hour regimen, and may be considered a standard supportive care measure in patients receiving high dose melphalan.

High Dose Melphalan

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 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.

Increased Risk

Background: The current commonly used regimens in newly diagnosed multiple myeloma (NDMM) utilize steroids (dexamethasone or prednisone) in various combinations: bortezomib, lenalidomide and dexamethasone (VRd), bortezomib, thalidomide and dexamethasone (VTd), daratumumab, lenalidomide and dexamethasone (DRd) and daratumumab, bortezomib, melphalan and prednisone (DVMP). However, steroid therapy may be associated with various adverse effects, including, but not limited to mood changes, insomnia, hypertension, hyperglycemia, osteoporosis, adrenal suppression, muscle weakness, and increased risk of opportunistic infections. A recent trial demonstrated improved tolerability of a regimen (Rd-R) involving an abbreviated course of dexamethasone, without compromising the efficacy in patients with intermediate-fit NDMM (Lorocca A., et al., ASH 2018). We designed a phase 2 clinical trial to examine the safety and efficacy of daratumumab, an anti-CD38 monoclonal antibody in combination with an all-oral regimen of ixazomib, a proteasome inhibitor, lenalidomide, an immunomodulatory drug, and modified dose dexamethasone (IRd). Patients and Methods: NDMM patients with measurable disease and adequate organ function were enrolled, irrespective of their transplant eligibility. The primary objective was to determine the rate of complete response (CR) to daratumumab-IRd. Treatment consisted of daratumumab, 16 mg/kg, weekly for two cycles, every other week during cycles 3-6 and then every 4 weeks, ixazomib, 4 mg days 1, 8, 15, lenalidomide, 25 mg days 1-21, and dexamethasone upto 40 mg intravenously weekly for no more than two cycles, followed by use only as a prophylactic premedication for daratumumab-associated infusion reactions. Myeloma risk stratification was assessed by cytoplasmic immunoglobulin fluorescence in-situ hybridization (cIg FISH) analysis. Results: Overall, 40 patients were accrued, with data available on all patients for analysis at the cutoff date of July 19, 2019. The median age at enrollment was 64.5 (33-81) years; 37.5% were female. Eight (20%) patients were high risk by FISH. The median number of cycles was 6 (2-11) and the median follow up was 6.1 (2-11.7) months. Among 40 patients who had received at least 2 cycles of therapy, responses were attained rapidly; at the end of cycle 2, 88% patients achieved at least a partial response and 33% at least a very good partial response (VGPR) that improved to 52% at the end of 4 cycles among 29 patients who had completed at least 4 cycles. The overall best confirmed response rate among all 40 patients (Figure 1) was 95%, including 10% stringent CR, 5% CR and 23% near CR (13% VGPR excluding nCR). Stem cell collection was completed in 17 patients so far, all of whom required filgrastim and plerixafor. The median CD34+ cell count was 7.7 (range 2.9-11.6) million/kg . All patients were alive and 39 (97.5%) patients were progression-free at last follow up. Four (10%) patients proceeded to autologous stem cell transplantation off study, per patient and/or investigator discretion (1 in CR, 2 in PR, 1 with progressive disease). Overall, 224 cycles have been administered across the study, with dose reduction/ hold required in a subset of patients; ixazomib (10%), lenalidomide (20%), daratumumab (0%) and dexamethasone (13%); the most frequent reasons for dose adjustment were skin rash and hematologic toxicities. A grade 3 or higher adverse event, at least possibly attributed to the study drugs, was observed in 40% of patients; hematologic in 30% (lymphopenia 25%, neutropenia 15%, thrombocytopenia 5% and anemia 2.5%) and non-hematologic in 18% of patients (hyperglycemia 8%, diarrhea 5%, infections 5%, ileus 2.5%, maculopapular rash 2.5%, and fatigue 2.5%). Updated results with additional 6 months of follow up and minimal residual disease assessment related data will be presented at the meeting. Conclusion: Our early results suggest that the combination of daratumumab, ixazomib, lenalidomide and modified dose dexamethasone is well-tolerated, with excellent activity, and does not adversely impact stem-cell mobilization in patients with NDMM.

Stem Cell Collection

Abstract RAD combination is highly effective for patients with relapsed/refractory multiple myeloma (MM), but there is limited data for its efficacy on newly-diagnosed patients (NDMM). Although lenalidomide exerts its function, at least partially, through the inhibition of interactions between myeloma and stromal cells, there is no information for the effect of RAD on bone metabolism and angiogenesis in NDMM. The primary endpoint of this phase 2 study was the assessment of overall response rate (ORR) after 4 cycles of RAD induction in NDMM patients who are eligible for ASCT. Secondary endpoints included toxicity, PFS, TTP, and TtNT. Exploratory endpoints included: i) the yield of stem cell collection after RAD; ii) the effects of RAD on biochemical markers of bone metabolism: CTX, TRACP-5b, bone-alkaline phosphatase (bALP), P1NP, osteocalcin, soluble RANKL, osteoprotegerin (OPG) and dickkopf-1 (Dkk-1) and iii) the effects of RAD on angiogenic cytokines: angiopoietin- (Angp) 1 & -2, angiogenin (Ang), VEGF and bFGF. Main inclusion criteria were: i) NDMM patients eligible for ΑSCT; ii) Κarnofsky performance status ≥ 60; iii) platelet count ≥100x109/L, neutrophil count ≥1.5x109/L. Main exclusion criteria included: i) serum ALT or AST >3-fold or bilirubin >2-fold the upper normal limit; ii) eGFR <60 ml/min; iii) prior malignancy; iv) severe heart or lung disease. According to treatment schedule, lenalidomide was administered at a dose of 25 mg, po, daily, on days 1-21 of a 28-day cycle; dexamethasone was given at a dose of 40 mg, po, on days 1, 8, 15, and 22, while adriamycin was administered as IV bolus infusion at a dose of 9 mg/m2, on days 1-4 of each cycle. RAD was repeated on day 28 if the neutrophil count was >1.5x109/L and the platelet count was >50x109/L. All patients received anti-coagulation with LMWH and monthly zoledronic acid. Between November 2014 and February 2016, 45 patients were enrolled. Median age was 56 years (range: 37-69 years); 28 (62%) patients had IgG, 12 (27%) IgA, 4 (9%) light chain only and one IgM MM; 18 (40%) patients had ISS-1, 22 (49%) ISS-2 and 5 (11%) ISS-3 disease. Osteolytic lesions were present in 33 (73%) patients. Seven (15.5%) patients had elevated serum LDH (>250 U/l) and 3 (6.6%) had hypercalcemia (>11 mg/dl). All but one patient completed 4 cycles of RAD. Best response included one (2.2%) CR, 8 (17.8%) VGPRs, 21 (46.7%) PRs, for an ORR of 66.7%, while 14 (31%) patients had stable disease and one progressed during the 4th cycle of treatment. Adverse events of grade 3 or 4 included: anemia (4 patients, 9%), neutropenia (3 patients, 6.6%), febrile neutropenia (one patient), hypocalcemia (one patient), acute renal failure (one patient), pulmonary embolism (one patient), fatigue (one patient) and pathological fracture (one patient). Forty (89%) patients had adequate stem cell collection post-RAD induction (mean±SD: 8.94±6.50 x106/kg CD34+ cells). Three patients failed to collect adequate number of stem cells and two patients refused to proceed to stem cell collection. Patients at baseline had elevated levels of CTX, TRACP-5b, sRANKL/OPG, Dkk-1, Ang, VEGF, VEGF-A, bFGF and reduced levels of Angp-1/Angp-2, bALP and P1NP compared to 30 healthy subjects of similar age and gender (p<0.01 for all comparisons). RAD therapy resulted in a reduction of circulating CTX (from 0.74±0.30 ng/ml at baseline to 0.54±0.14 ng/ml on day 28 of the fourth cycle; p=0.03), TRACP-5b (from 3.42±1.28 U/l to 1.25±1.10 U/l; p<0.01), Ang (from 420±120 ng/ml to 250±110 ng/ml; p=0.02), VEGF (from 260±97 pg/ml to 108±66 pg/ml; p=0.01) and bFGF (from 1.23±0.42 pg/ml to 0.32±0.18 pg/ml; p<0.01). On the contrary, RAD increased serum levels of bALP (from 11.5±5.1 μg/L to 15.3±6.7 μg/L, p=0.036), P1NP (from 45±15 mg/l to 110±57 mg/l; p=0.028) and Ang-1/Ang-2 ratio (13.3±10.9 to 18.8±12.6; p=0.022). These alterations occurred irrespective of response, although patients who achieved at least VGPR tended to have more profound differences in the above parameters. We conclude that RAD resulted in successful induction for NDMM patients and produced an ORR of approximately 67%. RAD reduced bone resorption and increased bone formation; the latter has not been previously described with lenalidomide-based regimens. Furthermore, RAD reduced angiogenic cytokines and this supports the action of the regimen also through the disruption of the interactions between myeloma and stromal cells.
