The Impact

Abstract Background: In patients with relapsed multiple myeloma (MM), Moreau and colleagues (Lancet Oncol, 2011) demonstrated that subcutaneous (SC) administration of bortezomib (BTZ) significantly reduced rates of adverse events (AE) compared to the intravenous (IV) formulation without loss of efficacy. Prospective data on SC BTZ in newly diagnosed MM are limited. We investigated the impact of SC versus IV BTZ in two different induction therapies for patients with newly diagnosed MM treated within the multicenter, prospective randomized MM5 trial of the German Myeloma Multicenter Group (GMMG). Methods: From 06/2010 until 11/2013, 604 patients were randomly assigned to receive 3 cycles of PAd (BTZ 1.3 mg/m2, days 1, 4, 8 and 11; Doxorubicin 9 mg/m2 IV, days 1-4; Dexamethasone 20 mg/d, orally, days 1-4, 9-12 and 17-20) or 3 cycles VCD (BTZ 1.3 mg/m2, days 1, 4, 8 and 11; Cyclophosphamide 900 mg/m2IV; day 1, Dexamethasone 40 mg/d, orally, days 1-2, 4-5, 8-9 and 11-12) for induction therapy. In the MM5 trial, induction therapy is followed by stem cell mobilization and harvest, high-dose therapy and Lenalidomide-based consolidation/maintenance therapy. Primary end points of the ongoing study are response to treatment after induction therapy and progression-free survival. Due to improved AE profile of SC compared to IV BTZ reported by Moreau, the administration of BTZ was changed from IV to SC in 02/2012. Therefore, we were able to perform an explorative analysis of 598 patients who received at least one dose of trial medication (PAd: n=150 IV / 140 SC; VCD: n=154 IV / 140 SC). 14 patients were excluded from the analysis because administration of BTZ was changed after start of induction therapy. We analyzed whether the route of administration influenced the applied cumulative BTZ dose, toxicity and efficacy of PAd and VCD. Results: The cumulative applied BTZ dose was significantly higher in patients treated with SC BTZ (PAd: 28.9 mg; VCD: 28.8 mg) compared to IV-treated patients (PAd: 27.6 mg; VCD: 27.9 mg; p = 0.007). Analysis of reported AEs associated to induction therapy revealed a significantly higher rate in patients treated with IV BTZ (65.1%) compared to SC-treated patients (55.7%, p = 0.02). AE > °II were reported more frequently in the IV group (IV: 52.0%; SC: 43.9%, p = 0.004). In detail, abnormal laboratory findings including leucopenia and thrombocytopenia (IV: 23.0%; SC: 16.4%, p = 0.05), metabolism and nutrition disorders (IV: 12.5%; SC: 5.4%, p = 0.004) and gastrointestinal disorders (IV: 9.9%; SC: 3.9%, p = 0.006) occurred more often in IV-treated patients. Analysis of peripheral neuropathy (PN) ≥ °II revealed no significant differences between IV and SC BTZ during the first two cycles of induction therapy (cycle 1: IV: 1.6%; SC: 2.5%; cycle 2: IV: 2.3%; SC: 3.6%) but PN occurred more often in IV-treated patients during the third cycle of induction therapy compared to the SC group (IV: 7.6%; SC: 1.8%, p = 0.001). Overall response rates (partial response or better) were not influenced by the route of administration in patients treated with PAd (IV: 72.7%; SC: 70.7%; p = 0.79) or VCD (IV: 77.9%; SC: 82.1%; p = 0.39). Analysis of the VCD arm showed that rates of VGPR or better were significantly higher in patients treated with IV BTZ compared to SC-treated patients (IV: 41.6%; SC: 28.6%, p = 0.02). Rates of VGPR or better were also higher for IV-treated patients in the PAd arm but did not reach statistical significance (IV: 36.7%; SC: 31.4%, p=0.39). Patient characteristics including baseline creatinine levels > 2 mg/dl, obesity or age at inclusion > 65 years did not influence efficacy of IV or SC BTZ in both arms. Conclusion: Last year we reported on the favorable toxicity profile and equal efficacy of VCD compared to PAd. With the current analysis we demonstrate that toxicity is further reduced with SC BTZ compared to IV. We therefore recommend VCD as induction therapy. However, we show for the first time a possible loss of efficacy in SC-treated patients. Therefore it remains unclear whether the reduced toxicity justifies the general application of SC BTZ in newly diagnosed, transplant-eligible patients or whether a prolonged treatment (4 x VCD SC) may reduce toxicity while achieving similar efficacy. Further studies are warranted since our results are partially in contrast with the previously presented data in relapsed MM and the ongoing MM5 trial was initially not designed to prospectively investigate the effect of SC or IV BTZ.

The Impact

Abstract Background: Approximately 20–40% of pts with NDMM present with RI, which is associated with a negative impact on survival (Rajkumar, 2005). In the pivotal phase 3 FIRST trial (median follow-up 37 months [mos]), continuous Rd improved progression-free survival (PFS) vs. melphalan-prednisone-thalidomide (MPT) in elderly NDMM pts by 28% (25.5 vs. 20.7 mos; HR = 0.72; P < 0.01) (Facon, Blood 2013). Although 121 pts receiving continuous Rd are still on Tx, the interim overall survival (OS) analysis showed a 22% reduction in the risk of death in favor of continuous Rd vs. MPT (HR = 0.78; P = 0.02). The present analysis was conducted to determine the impact of RI on PFS, OS, and time to 2nd antimyeloma Tx (AMT) as clinical study outcomes. Methods: Pts were randomized to 3 Tx arms: continuous Rd until progression (n = 535); Rd for 18 cycles (72 weeks) (Rd18; n = 541); or MPT for 12 cycles (72 weeks) (n = 547). Enrolled NDMM pts were categorized according to their renal function: 24% had normal renal function (creatinine clearance [CrCl] ≥ 80 mL/min), 44% presented with mild RI (≥ 50 and < 80 mL/min), 23% had moderate RI (≥ 30 and < 50 mL/min), and 9% had severe RI (< 30 mL/min). Pts requiring dialysis were excluded. Lenalidomide starting dose was 25 mg QD for pts with normal renal function or mild RI, 10 mg QD for moderate RI, and 15 mg QOD for severe RI. Melphalan dose was reduced by 50% in pts with moderate or severe RI. The primary endpoint was PFS (continuous Rd vs. MPT); secondary endpoints were OS, overall response rate, time to response, duration of response, time to Tx failure, time to 2nd AMT, health-related quality of life, safety, and improvement in renal function from baseline. Improvement in RI was defined as shifts from baseline to most extreme post-baseline value of the calculated CrCl as a measure of renal function during the active Tx (N = 1484). Results: A PFS benefit favored continuous Rd vs. MPT irrespective of the degree of renal function (Table 1): there was a benefit in pts with normal renal function (HR = 0.72 (0.51–1.02); P = 0.06), and better in pts with mild RI (HR = 0.79 (0.62–1.00); P = 0.05) and moderate RI (HR = 0.62 (0.45–0.85); P < 0.01). A PFS benefit was also seen with continuous Rd vs. Rd18 (a secondary comparison) in pts with mild RI and moderate RI (P < 0.01 for both). An interim OS benefit with continuous Rd vs. MPT was observed in most renal subgroups. Similar results were observed between Rd18 and MPT in terms of PFS or interim OS in any of the renal subgroups. Continuous Rd, compared with Rd18 or MPT, extended time to 2nd AMT in most renal groups except severe RI (CrCl < 30mL/min) (Table 2). Improvement in RI was observed more frequently in pts treated with continuous Rd than those with Rd18 or MPT: improvement of mild RI, 48%, 43%, and 48%, respectively; of moderate RI, 67% 61%, and 62%; and of severe RI, 64%, 59%, and 56%. Overall, < 5% of pts in any Tx group experienced a worsening in renal function status during Tx (continuous Rd 2.2%; Rd18 2.8%; MPT 2.7%). The most common grade 3–4 adverse events (AEs) for these Txs were anemia, neutropenia, thrombocytopenia, deep-vein thrombosis/pulmonary embolism (DVT/PE), and peripheral sensory neuropathy (Table 3). Tx discontinuation due to AEs increased in pts with moderate and severe RI, regardless of the type of Tx (Table 3). Conclusions: PFS, OS (at interim analysis), and time to 2nd AMT outcomes generally improved continuous Rd vs. Rd18 or MPT in transplant-ineligible NDMM pts with normal renal function, and in those with mild or moderate RI. The small number of pts in the severe RI group precluded a meaningful conclusion. Continuous Rd was generally well tolerated and renal function improved in the majority of pts during Tx with continuous Rd vs. Rd18 or MPT.

Background: A variety of risk factors have been described in multiple myeloma and current risk assessment incorporates ISS stage with specific FISH results and serum LDH (R-ISS). However, this model does not include all the current abnormalities described as prognostic for survival in multiple myeloma. Importantly, the impact of many of these high-risk abnormalities are not uniform. We examined if we can better integrate FISH results into a risk assessment tool to better predict the outcomes of newly diagnosed MM. Patients and methods: We studied a cohort of 1316 patients with FISH done within 6 months of diagnosis of MM, in whom results for commonly observed abnormalities were available. We specifically examined the individual impact of common translocations involving chromosome 14, MYC rearrangements, chromosome 1q gain (single or multiple duplication) and del13q/monosomy 13. A risk assessment system was developed, weighting each abnormality according to their Risk Ratio and integrating ISS stage and serum LDH into the final model construction. Overall survival was calculated from diagnosis, with those alive at last follow up being censored. Results: We first examined the impact of each of the above FISH abnormalities: 1) high risk translocations [t(4;14), t(14;16), or t(14,20)], 2) trisomies, 3) t(11;14), 4) MYCrearrangements, 5) del13q/monosomy 13, and 6) 1q gain . Each of the abnormalities, except for t(11;14), was prognostic for survival (Table 1 with the risk ratios). For 1q gain, the median OS was NR, 105 mos and 79 mos respectively for no abnormality, duplication of 1 copy and duplication of multiple copies, (p<0.001). On multivariate analysis, t(11;14) and trisomies were no longer prognostic for overall survival (Table 1). The cumulative impact of abnormalities demonstrated worsening survival in the presence of increasing numbers of abnormalities (Figure 1). Including ISS stage 3 and LDH > ULN as additional variables for prognostication indicated both were individually prognostic for OS. In a multivariate analysis, including these two and FISH abnormalities, 1q gain and LDH were not independently prognostic. The final model consisted of HR translocations, MYCrearrangements, del17p/monosomy 17, del13q/monosomy 13, and ISS stage 3. Each of these variables was weighted using their risk ratio and a composite score was developed using 998 patients for whom all variables were available (range: 0-7.9; median 1.8). Three patient groups were characterized: group 1 (0; 32%), group 2 (1-4; 58%) and group 3 (>4; 10%) with a median OS of 53 mos, 106 mos, and NR, respectively, p <0.001 (Figure 2). Conclusion: Using the most relevant FISH and laboratory factors, in a large cohort of patients, we refined the current system to develop a risk stratification system that predicts survival in patients with newly diagnosed MM treated with contemporary treatment regimens. This needs validation in future studies. Disclosures Kumar: Janssen: Consultancy, Research Funding; Takeda: Research Funding; Celgene: Consultancy, Research Funding.

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.

Depth Of Response

Abstract Background: Induction therapy prior to consolidation with autologous stem cell transplantation (ASCT) continues to improve with the use of proteasome inhibitors and imids and combination regimens such as RVD. Bortezomib-based induction therapy has improved overall response rates (ORR) prior to transplant, which has translated to improvements in ORR and progression free survival post ASCT. However, complete remission (CR) rates with RVD remain low (10-15%) after 4 cycles of induction therapy. Panobinostat, a histone deacetylase inhibitor, in combination with bortezomib/dexamethasone, has demonstrated a significant improvement in depth of response and progression free survival in patients (pts) with relapsed myeloma as seen in PANORMA I. Preclinical data demonstrate synergy between the combination of bortezomib and panobinostat. We undertook a phase I/Ib trial in pts with newly diagnosed myeloma (NDMM) of RVD + Panobinostat to establish the safety of the combination and goal of improving the depth of response with induction therapy prior to ASCT. Methods: The primary objective was to determine the maximum tolerated dose (MTD) and safety/tolerability of RVD + panobinostat in NDMM. Secondary objectives were to determine efficacy as measured by the CR/nCR rate after 4 cycles, ORR, tolerability/toxicity, and progression free survival. Pts had to have NDMM with indication for therapy, candidates for ASCT with and had adequate organ function. Panobinostat was administered on days 1, 3, 5, 8, 10, 12; bortezomib 1.3 mg/m2 was administered subcutaneously on days 1, 4, 8, 11; lenalidomide 25 mg on days 1-14; dexamethasone 20 mg on days 1, 2, 4, 5, 8, 9, 11, and 12 on a 21 day cycle. Dose-escalation of panobinostat used a standard 3+3 schema with dose-limiting toxicities (DLTs) assessed during cycle 1. Three dose levels were studied with Panobinostat escalated from 10 to 20 mg. Adverse events (AEs) were graded by NCI-CTCAE v4, while responses were assessed by the modified International Uniform Response Criteria. Results: 22 pts were enrolled; 12 pts in the completed phase 1 dose escalation portion of the study and 10/20 in the ongoing dose expansion. The median age was 61 (range 53-79); ISS stage I 12; stage II 7/20; stage III in 3/20 pts. No DLTs were observed in 3 pts dosed in cohort 1, with Panobinostat at 10 mg. In cohort 2, panobinostat was dosed at 15 mg, 2/6 pts encountered a DLT. One patient experienced Grade 4 (G4) thrombocytopenia, and the second patient had G3 diarrhea without supportive measures, for <12 hours and resolved with supportive measures. In cohort 1, 3 additional patients were enrolled and no DLTs were encountered in the remaining 3 pts. The final recommended dose was Panobinostat 10 mg in combination with RVD in NDMM. Treatment emergent SAEs related to therapy observed in 5 pts with 2 incidences of G3 diarrhea; 2 pts with atrial fibrillation; and other events included G4 thrombocytopenia; G3 bacteremia, G3 cellulitis, G3 myocardial infarction (MI), G3 pulmonary emboli; G3 pneumonia. Hematologic adverse events G3/4 included anemia 3/22; neutropenia 4/22; thrombocytopenia 7/22. G3/4 nonhematologic toxicities included ALT elevation (n=2); AST elevation (n=1); constipation (n=2); diarrhea (n=2); fatigue/muscle weakness (n=2); MI (n=1); pneumonia (n=3). Among 18/22 pts who have completed 4 cycles of therapy and are evaluable for efficacy, the ORR (≥PR) was 100%: including nCR/CR in 5/18 (28%), VGPR in 5/18 (28%), PR in 8/18 (44%). Conclusions: MTD has been established at level 1, with panobinostat 10 mg and full dose RVD in NDMM. The DLTs were diarrhea (irrespective of supportive care) and thrombocytopenia. This is the first experience with panobinostat and subcutaneous bortezomib and first experience in combination with RVD. The combination is well tolerated with limited toxicity and side effects can be managed with supportive care. The preliminary activity after 4 cycles of therapy demonstrated a high ORR of 100% and a promising depth of response with a nCR/CR of 27%. Enrollment in a dose expansion cohort is near completion and full data will be presented at ASH.

Increased Risk

Introduction Immunomodulatory agents (IMiD's) are associated with an increased risk of venous thromboembolism (VTE), particularly when combined with high dose steroids. Studies evaluating the use of lenalidomide-bortezomib-dexamethasone (RVD) and carfilzomib-lenalidomide-dexamethasone (KRD) in the frontline setting for multiple myeloma (MM) have reported a 6% and 24% incidence of thrombosis, respectively, despite primary thrombotic prophylaxis with aspirin (ASA) (Richardson, et al. Blood. 2010; Korde, et al. JAMA Oncol 2015). Recent data, including the Hokusai VTE Cancer Trial, have suggested that safety and efficacy of direct oral anticoagulants (DOACs) are preserved in the setting of treatment of solid malignancy-associated thrombosis (Raskob, et al. N Engl J Med. 2018; Mantha, et al. J Thromb Thrombolysis. 2017). Despite this data, there is limited experience and use of DOACs in prevention of thromboses in the setting of hematologic malignancies, specifically MM. After careful review of literature, since early 2018, we changed our clinical practice and routinely placed newly diagnosed MM (NDMM) patients receiving KRD at Memorial Sloan Kettering Cancer Center (MSKCC) on concomitant rivaroxaban 10 mg once daily, regardless of VTE risk stratification. In the following abstract, we present VTE rates and safety data for newly diagnosed MM patients receiving RVD with ASA vs. KRD with ASA vs. KRD with rivaroxaban prophylaxis. Methods This was an IRB-approved, single-center, retrospective chart review study. All untreated patients with newly diagnosed MM, receiving at least one cycle of RVD or KRD between January 2015 and October 2018 were included. The period of observation included the time between the first day of therapy until 90 days after completion of induction therapy. Patients were identified by querying the pharmacy database for carfilzomib or bortezomib administration and outpatient medication review of thromboprophylaxis with rivaroxaban or ASA. VTE diagnoses were confirmed by ICD-10 codes and appropriate imaging studies (computed tomography and ultrasound). Descriptive statistics were performed. Results During the observation period, 241 patients were identified to have received RVD or KRD in the frontline (99 RVD with ASA; 97 KRD with ASA; 45 KRD with rivaroxaban). Baseline characteristics were well distributed among the three arms, with a median age of 60 (30-94) in the RVD ASA arm, 62 (33-77) in the KRD ASA arm, and 60 (24-79) in the KRD rivaroxaban arm. Patients had International Staging System (ISS) stage 3 disease in 13% (N=13), 9.3% (N=9), and 11% (N=5) of the RVD ASA, KRD ASA, and KRD rivaroxaban arms, respectively. Median weekly doses of dexamethasone were higher in both KRD arms, 40 mg (20-40) vs. 20 mg (10-40) in the RVD ASA arm. The average initial doses of lenalidomide were 22 mg in the RVD ASA arm compared to 25 mg in both the KRD ASA and KRD rivaroxaban arms. After querying the pharmacy database, no patients were identified to have a history or concomitant use of erythropoietin stimulating agent (ESA) use. Treatment-related VTE's occurred in 4 patients (4.0%) in the RVD ASA arm, 16 patients (16.5%) in the KRD ASA arm, and in 1 patient (2.2%) in the KRD rivaroxaban arm. Average time to VTE was 6.15 months (Range 5.42, 9.73) after treatment initiation in the RVD ASA group, while it was 2.61 months (Range 0.43, 5.06) in the KRD ASA group and 1.35 months in the KRD rivaroxaban group. Minor, grade 1 bleeding events per the Common Terminology Criteria for Adverse Events (CTCAE) were identified in 1 (1.1%) patient in the RVD ASA arm, 5 (5.2%) patients in the KRD ASA arm, and 1 (2.2%) patient in the KRD rivaroxaban arm. Conclusion More efficacious MM combination therapies have been found to increase the risk of VTE when using ASA prophylaxis, indicating better thromboprophylaxis is needed. We found patients receiving ASA prophylaxis with KRD were more likely to experience a VTE and these events occurred earlier compared to patients receiving ASA prophylaxis with RVD. Importantly, the rate of VTE was reduced to the same level as ASA prophylaxis with RVD when low-dose rivaroxaban 10 mg daily was used with KRD, and without necessarily increasing bleeding risk. Our retrospective data support the development of prospective clinical trials further investigating DOAC use in thromboprophylaxis for NDMM patients receiving carfilzomib-based treatments.

Introduction: Abnormal metaphase cytogenetics are associated with inferior survival in newly diagnosed multiple myeloma (MM). These abnormalities are only detected in one third of cases due to the low proliferative rate of plasma cells. It is unknown if metaphase cytogenetics improve risk stratification when using contemporary prognostic models such as the revised international staging system (R-ISS), which incorporates interphase fluorescence in situ hybridization (FISH). Aims: The aims of this study were to 1) characterize the association between abnormalities on metaphase cytogenetics and overall survival (OS) in newly diagnosed MM treated with novel agents and 2) evaluate whether the addition of metaphase cytogenetics to R-ISS, age, and plasma cell labeling index (PCLI) improves model discrimination with respect to OS. Methods: We analyzed a retrospective cohort of 483 newly diagnosed MM patients treated with proteasome inhibitors (PI) and/or immunomodulators (IMID) who had metaphase cytogenetics performed prior to initiation of therapy. Abnormal metaphase cytogenetics were defined as MM specific abnormalities, while normal metaphase cytogenetics included constitutional cytogenetic variants, age-related Y chromosome loss, and normal metaphase karyotypes. Multivariable adjusted proportional hazards regression models were fit for the association between known prognostic factors and OS. Covariates associated with inferior OS on multivariable analysis included R-ISS stage, age ≥ 70, PCLI ≥ 2, and abnormal metaphase cytogenetics. We devised a risk scoring system weighted by their respective hazard ratios (R-ISS II +1, R-ISS III + 2, age ≥ 70 +2, PCLI ≥ 2 +1, metaphase cytogenetic abnormalities + 1). Low (LR), intermediate (IR), and high risk (HR) groups were established based on risk scores of 0-1, 2-3, and 4-5 in modeling without metaphase cytogenetics, and scores of 0-1, 2-3, and 4-6 in modeling incorporating metaphase cytogenetics, respectively. Survival estimates were calculated using the Kaplan-Meier method. Survival analysis was stratified by LR, IR, and HR groups in models 1) excluding metaphase cytogenetics 2) including metaphase cytogenetics and 3) including metaphase cytogenetics, with IR stratified by presence and absence of metaphase cytogenetic abnormalities. Survival estimates were compared between groups using the log-rank test. Harrell's C was used to compare the predictive power of risk modeling with and without metaphase cytogenetics. Results: Median age at diagnosis was 66 (31-95), 281 patients (58%) were men, median follow up was 5.5 years (0.04-14.4), and median OS was 6.4 years (95% CI 5.7-6.8). Ninety-seven patients (20%) were R-ISS stage I, 318 (66%) stage II, and 68 (14%) stage III. One-hundred and fourteen patients (24%) had high-risk abnormalities by FISH, and 115 (24%) had abnormal metaphase cytogenetics. Three-hundred and thirteen patients (65%) received an IMID, 119 (25%) a PI, 51 (10%) received IMID and PI, and 137 (28%) underwent upfront autologous hematopoietic stem cell transplantation (ASCT). On multivariable analysis, R-ISS (HR 1.59, 95% CI 1.29-1.97, p < 0.001), age ≥ 70 (HR 2.32, 95% CI 1.83-2.93, p < 0.001), PCLI ≥ 2, (HR 1.52, 95% CI 1.16-2.00, p=0.002) and abnormalities on metaphase cytogenetics (HR 1.35, 95% CI 1.05-1.75, p=0.019) were associated with inferior OS. IR and HR groups experienced significantly worse survival compared to LR groups in models excluding (Figure 1A) and including (Figure 1B) the effect of metaphase cytogenetics (p < 0.001 for all comparisons). However, the inclusion of metaphase cytogenetics did not improve discrimination. Likewise, subgroup analysis of IR patients by the presence or absence of metaphase cytogenetic abnormalities did not improve risk stratification (Figure 1C) (p < 0.001). The addition of metaphase cytogenetics to risk modeling with R-ISS stage, age ≥ 70, and PCLI ≥ 2 did not improve prognostic performance when evaluated by Harrell's C (c=0.636 without cytogenetics, c=0.642 with cytogenetics, absolute difference 0.005, 95% CI 0.002-0.012, p=0.142). Conclusions: Abnormalities on metaphase cytogenetics at diagnosis are associated with inferior OS in MM when accounting for the effects of R-ISS, age, and PCLI. However, the addition of metaphase cytogenetics to prognostic modeling incorporating these covariates did not significantly improve risk stratification. Disclosures Lacy: Celgene: Research Funding.

Abstract Abstract 42 We prospectively compared thalidomide-dexamethasone (TD) with bortezomib-thalidomide-dexamethasone (VTD) as induction therapy before, and consolidation after, double autologous stem-cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma (MM). Three 21-d cycles of either VTD (V, 1.3 mg/m2 twice-weekly; T, 200 mg/d through d 1 to 63; D, 320 mg/cycle) or TD were given as induction therapy. Consolidation therapy comprised two 35-d cycles of VTD (V, 1.3 mg/m2 once-weekly; T, 100 mg/d through d 1 to 70; D, 320 mg/cycle) or TD. 474 patients randomized to the VTD (n=236) or TD (n=238) arm were analyzed on an intention-to-treat basis for response rate, PFS and OS. Centrally reassessed CR/nCR rate was significantly higher in the VTD compared with the TD arm after all treatment phases, including induction therapy (30% vs 10%, p<0.0001), double autotransplantation (54% vs 42%, p=0.008) and consolidation therapy (60% vs 44%, p=0.001). Best confirmed overall CR/nCR rate was 71% in the VTD arm compared with 52% in the TD arm (p<0.0001); the corresponding values for VGPR or better were 89% vs 72%, respectively (p<0.0001). To evaluate the role of consolidation therapy we performed a per-protocol analysis of 323 patients, 161 treated with VTD and 162 with TD. Overall, upgraded responses with VTD and TD as consolidation therapy were observed in 55% vs 37% of patients, respectively (p=0.01; OR:1.15-3.77). Furthermore, the probability to improve responses from less than CR before consolidation to CR after consolidation was 28% with VTD vs 15% with TD (p=0.02; OR:1.07-4.57) (p=0.003 using the Mc Nemar's test). Post-consolidation molecular detection of minimal residual disease was the objective of a substudy; detailed results are reported in a separate abstract. Briefly, both qualitative and quantitative analyses confirmed the statistically significant superiority of VTD over TD in effecting higher rates of molecular remissions and reducing the burden of residual myeloma cells after ASCT. Any grade 3–4 non-hematologic adverse events were 10% with VTD (peripheral neuropathy: 1.3%, skin rash: 0.6%) vs 12% with TD. With a median follow-up of 31 months, median PFS was 42 months in the TD arm and was not yet reached in the VTD arm (44-month projected rate: 61%) (HR: 0.62 [CI: 0.45–0.87], p=0.006). Superior PFS in the VTD vs TD arm was retained across patient subgroups with poor prognosis, including those with t(4;14) and/or del(17p). Randomization to VTD overcome the adverse influence of t(4;14) on PFS (40-month projected rates: 69% vs 67% according to the presence or absence of this abnormality, respectively; p=0.6). By the opposite, in the TD arm corresponding median PFS values were 24.5 vs 41.5 months, respectively (p=0.01). The small numbers of patients with del(17p) in both arms of the study precluded a statistical comparison with del(17p)-negative group. In a multivariate analysis, variables favorably influencing PFS were beta2-m lower than 3.5 mg/L (HR:0.47; p=0.000), absence of t(4;14) and/or del(17p) (HR:0.52; p=0.000), randomization to VTD arm (HR:0.57; p=0.002), attainment of at least VGPR (HR:0.50; p=0.009) and CR (HR:0.8; p=0.01). No statistically significant difference between the overall treatment protocols was seen in terms of OS, although curves seemed to initially diverge after 40 months (44-month projected rates: 84% vs 74% for VTD and TD arms, respectively). A multivariate analysis showed the independent role of absence of t(4;14) and/or del(17p) (HR:0.42; p=0.003), ISS stage1-2 (HR:0.49; p=0.02) and randomization to VTD (HR:0.53; p=0.04) in prolonging OS. When time-dependent CR entered the model, absence of t(4;14) and/or del(17p) and less advanced ISS stage retained their positive prognostic value; attainment of CR (strictly related to VTD randomization) was an additional favorable variable. In conclusion, in comparison with the TD arm of the study, 1) VTD induction emerges as a new standard of care for maximizing the degree and speedy of tumor reduction in preparation for ASCT; 2) VTD consolidation effected significantly higher rates of upgraded responses, including CR, and of molecular remissions; 3) double ASCT incorporating VTD as induction and consolidation therapy resulted in significantly longer PFS, a benefit confirmed in a multivariate regression analysis and maintained in the subgroup of patients with adverse cytogenetic abnormalities.

Abstract Abstract 5032 Background: In the past decade, with the availability of novel therapies, the paradigm for myeloma management has changed. In 2010 it is especially important to understand baseline features and initial treatment decisions. The goal of the Connect MM® registry is to characterize patients with newly diagnosed active myeloma from 200 US sites. Approximately 80% of the patient population will be enrolled from community-based practices and 20% from academic centers. An electronic case report form was developed to collect clinical data, physician choices, patient health-related quality of life (HRQoL) and response, as well as data on survival end points. This is a prospective, observational, longitudinal study with a target accrual of 1,500 patients in 3 years, with a 5 year follow-up from the time of informed consent. There are no mandated treatments or clinical assessments. However, there are data collection requirements for diagnosis and disease monitoring. Results: Since late 2009, 340 patients from 135 sites have been accrued and were included in this interim analysis. Current study demographics include: 60% male, 83% white, and 14% black, with a median age of 67 years. Thus far, 97% have been enrolled from community-based practices. All patients met study enrollment criteria and had active myeloma at entry; prior monoclonal gammopathy of unknown significance (MGUS) was reported in 13% and smoldering MM in 8%. International Staging System (ISS) staging for evaluable patients were 26.3%, 36.4%, 37.3% for stages I, II, and III, respectively. Durie-Salmon Stage (A or B) were 13%, 35%, 52% for stages I, II, and III, respectively. Staging procedures included 82% skeletal survey; 44% computed tomography (CT); 40% magnetic resonance imaging (MRI); 7% positron emission tomography (PET); 2% PET/CT; and 4% had no imaging. International Myeloma Working Group (IMWG) CRAB criteria were assessed in all enrolled patients; 9% had hypercalcemia, 18% renal insufficiency, 36% anemia, and 66% had bone lesions. Median values were: calcium 9.5 mg/dL; serum creatinine 1.1 mg/dL; hemoglobin 10.9 gm/dL. Only 9% of patients had 3 or 4 CRAB features, while 49% had only 1 feature and 26% were asymptomatic (ECOG=0). The incidence of baseline peripheral neuropathy was 6%. Initial pain led to radiation therapy for 10% of patients, with 16% having vertebroplasty or kyphoplasty. Cytogenetic studies were performed at baseline in 64% of patients and fluorescence in situ hybridization (FISH) studies in 54%. Cytogenetics and FISH were normal in 27% of patients, while in 20% both were abnormal in patients who had both performed. FISH was abnormal with normal cytogenetics in 41% and only 2% had normal FISH but abnormal cytogenetics. The most common FISH abnormalities were: 13 q- (31%), 17 p- (28%), t(4; 14) (16%). Freelite® testing was performed in 56% of patients with an abnormal ratio in 94% [rFLC]. Of evaluable patients receiving frontline therapy 98% of patients received a novel agent and only 3 patients (1.4% of treated patients) received melphalan/prednisone. Two drug combinations were used in 53%, 3 drugs in 26%, 4 drugs in 1.3%, and single agents were used in 21% of the patients. The most common regimens were: bortezomib+dexamethasone (28%), lenalidomide+dexamethasone (20%), and bortezomib+lenalidomide+ dexamethasone (15%). Conclusion: These baseline features and treatment choices characterize myeloma patients primarily in community-based practices in the US in 2010. As academic centers enroll more patients, we will be able to further characterize that population. Of particular note, 26% of patients were asymptomatic at baseline but had biochemical evidence of myeloma and met enrollment criteria; conversely 95% had an abnormal rFLC and 73% had abnormal chromosome results. The Connect MM® registry will provide data regarding patient features as they pertain to patterns in testing and treatment in the clinical practice setting, as well as response and survival outcomes.

Abstract Introduction Frontline NIL continues to show benefit over IM in pts with Philadelphia chromosome-positive (Ph+) CML-CP, with higher rates of major molecular response (MMR; BCR-ABLIS ≤ 0.1%) and MR4.5 (BCR-ABLIS ≤ 0.0032%), lower rates of progression to accelerated phase (AP)/blast crisis (BC) and fewer new BCR-ABL mutations on treatment in the Evaluating Nilotinib Efficacy and Safety in Clinical Trials–Newly Diagnosed Pts (ENESTnd) trial. Here, we report data with a minimum follow-up (f/u) of 4 y; updated data based on 5 y of f/u will be presented. Methods Adults with newly diagnosed Ph+ CML-CP (N = 846) were randomized to NIL 300 mg twice daily (BID; n = 282), NIL 400 mg BID (n = 281), or IM 400 mg once daily (QD; n = 283). Progression and overall survival (OS) events were collected prospectively during study f/u, including after discontinuation of study treatment. Efficacy in the NIL 300 mg BID and IM arms was evaluated based on achievement of EMR (BCR-ABLIS ≤ 10% at 3 mo). Results At 4 y, ≥ 87% of pts remained on study in each arm and 57%-69% remained on core treatment (Table). Rates of MMR and MR4.5 by 4 y were significantly higher with NIL vs IM. Significantly fewer pts progressed to AP/BC on NIL vs IM (on core treatment: 0.7%, 1.1%, and 4.2%; on study: 3.2%, 2.1%, and 6.7% [NIL 300 mg BID, NIL 400 mg BID, and IM arms, respectively]). Of 17 pts across the 3 arms who progressed on core treatment, 11 (65%) had never achieved complete cytogenetic response and none had achieved MR4.5. Fewer mutations have emerged in the NIL arms vs the IM arm; in y 4, mutations emerged in 2 pts (1 pt with T315I on NIL 300 mg BID; 1 pt with F317L on IM). More pts achieved EMR in the NIL 300 mg BID arm vs the IM arm (91% vs 67%). Pts with EMR had significantly higher rates of progression-free survival (PFS) and OS at 4 y vs pts with BCR-ABL > 10% at 3 mo. Among pts with BCR-ABL > 10% at 3 mo, more progressions to AP/BC occurred in the IM arm (n = 14) vs the NIL 300 mg BID arm (n = 2); half of these pts progressed between 3 and 6 mo. In pts with intermediate or high Sokal risk, PFS and OS at 4 y were higher in both NIL arms vs the IM arm. No new safety signals were detected. Selected cardiac and vascular events were more common on NIL vs IM (by 4 y, peripheral arterial occlusive disease [PAOD] in 4 [1.4%], 5 [1.8%], and 0 pts; ischemic heart disease [IHD] in 11 [3.9%], 14 [5.1%,] and 3 [1.1%] pts; and ischemic cerebrovascular events in 3 [1.1%], 5 [1.8%], and 1 [0.4%] pts in the NIL 300 mg BID, NIL 400 mg BID, and IM arms, respectively). In the NIL 300 mg BID arm, 2 of 11 IHD events occurred between 3 and 4 y (all 4 PAOD events occurred in the first 2 y). In the NIL 400 mg BID arm, 2 of 5 PAOD events and 3 of 14 IHD events occurred between 3 and 4 y. Most pts (7 of 9) with a PAOD event on NIL were at high risk due to a combination of baseline risk factors. Conclusions NIL, a standard-of-care frontline therapy option for newly diagnosed CML-CP pts, affords superior efficacy compared with IM, including higher rates of EMR (which is associated with improved long-term outcomes), higher rates of MR4.5 (a key eligibility criterion for many studies of treatment-free remission), and a lower risk of disease progression. NIL continues to show good tolerability with long-term f/u. While selected cardiac and vascular events (including PAOD) are slightly more frequent on NIL vs IM, no increase in annual incidence of these events over time has been observed.

Abstract Background: Assessment of malignant plasma cell cycling via plasma cell labeling index (PCLI) has been a validated prognostic tool in multiple myeloma (MM) but the test requires specialized technical expertise and is not widely available. Ki67 is a well-known protein marker of cellular proliferation on immunohistochemical (IHC) staining with prognostic utility in other malignancies. In an effort to develop a simpler system to provide analogous information to PCLI, we used a novel IHC co-staining technique for CD138 and Ki67 to quantify plasma cells in active cycling. We then performed a retrospective analysis of the ratio of Ki67/CD138 (Ki67%) in newly diagnosed patients with multiple myeloma receiving 1st-line therapy to correlate with clinical outcomes. Methods: A retrospective cohort study of patients (pts) with treated symptomatic MM was performed by interrogation of the clinical database at the Weill Cornell Medical College / New York Presbyterian Hospital. For inclusion in the analysis, subjects must have started first-line treatment in the period of 2005-2010, and had available bone marrow biopsies. Double-staining with Ki67 and CD138 was performed by IHC. The Ki67% was calculated as the percent of plasma cells expressing CD138 that were also found to express Ki67. Treatment outcomes were stratified and compared based on %Ki67. Response was determined by monthly serum protein electrophoresis / immunofixation (IFX) with free light chain analysis according to International Multiple Myeloma Working Group (IMWG) guidelines. Pts who were IFX negative but had no subsequent bone marrow biopsy were classified as being in unconfirmed complete remission. Results: We identified 151 patients with newly diagnosed MM and available %Ki67 expression who received first-line therapy over the period of 2005-2010. Patient were subdivided into two groups based on %Ki67: Low: %ki67 <= 5%, n = 87; and High: %Ki67 >5, n=64, to allow for comparison of treatment response and survival analysis. Specific therapeutic agent exposure history did not differ significantly between patients. Both groups had similar depth of response rates (ORR) to front-line therapy, Table 1. Median progression-free survival for the high versus low %Ki67 groups approached statistical significance at 54 months (95% CI 30.8,67.4) versus 26.9 months (95% CI 21.6,40.2), respectively (P = 0.083). At data cut-off, there were 30 deaths in the low %Ki67 group (1-yr OS 93%, 5-yr OS 71%) and 36 deaths in the high %Ki67 group (1-yr OS 94%, 5-yr OS 62%). Median overall survival (OS) was not reached for Ki67% <= 5% (95% CI 97.3,NR) vs. 78.9 months (95% CI 55.9,93.1) for Ki67% > 5%, (P = 0.0434), Figure 1. Multivariate cox regression for factors with influence on OS showed that only high-risk cytogenetics (HR 2.05, 95% CI 1.17, 2.92, P = 0.027), ISS (HR 1.835, 95% CI 1.33, 3.60, P = 0.000), and %Ki67 group status had an independent effect on survival outcome. Low (<=5%) versus high (>5%) %Ki67 influenced overall survival with a hazard ratio of 1.76 (CI 1.07,2.92, P = 0.027). Survival after ASCT was significantly longer in the low %Ki67 group with median OS not reached (95%CI, 97.3, NR) versus 86.9 months (95% CI 43.9, NR) for high %Ki67 group (P = 0.04). Discussion: The ratio of IHC double positive Ki67 and CD138 of > 5% is an independent prognostic marker for overall survival in newly diagnosed MM undergoing 1st line therapy. The %Ki67 serves as a simpler and widely available analog to PCLI that can be presently performed in most hematopathology laboratories.
