AbstractThe clinical outcomes of 169 patients enrolled in the first clinical trial of thalidomide for advanced or refractory myeloma are updated. Seventeen patients remain alive and 10 are event-free, with a median follow-up of 9.2 years. According to multivariate analysis of pretreatment variables, cytogenetic abnormalities, present in 47% of patients within 3 months of enrollment, and λ light chain isotype both affected overall survival and event-free survival adversely. Forty percent of the 58 patients lacking these 2 unfavorable features, one-half of whom had no disease recurrence, survived at least 6 years, in contrast to fewer than 5% among those with 1 or 2 risk features (P < .001). Patients who had received cumulative thalidomide doses in excess of 42 g in the first 3 months enjoyed superior overall and event-free survival. The poor outcome associated with λ-type myeloma may relate to its overrepresentation in molecularly defined high-risk disease gleaned from studies in newly diagnosed myeloma.

Abstract Abstract 4142 Introduction: High dose chemotherapy combined with autologous stem cell transplantation (ASCT) as opposed to conventional chemotherapy improved progression free survival (PFS) and overall survival (OS) in multiple myeloma (MM) and is currently the standard of care for newly diagnosed MM patients less than 65 years old. Over the last decade, novel agents such as lenalidomide or bortezomib have dramatically improved MM outcomes with similar response rates as ASCT and the role of upfront ASCT has become more controversial. Therefore the goal of this randomized clinical trial is to determine the role of upfront ASCT in newly diagnosed myeloma patients receiving novel agent lenalidomide and low-dose dexamethasone induction. Methods: Patients aged ≥18 years with newly confirmed, measurable MM in stage 2 and 3 (Salmon Durie) and meeting CRAB criteria were enrolled. Patients were randomized to transplant (Arm A) or to non-transplant (Arm B). Patients in Arm A received 4 cycles of lenalidomide (25mg days 1 – 21) plus low-dose dexamethasone (40mg days 1,8,15,22) followed by ASCT conditioned with 200 mg/m2 melphalan (LD+ASCT); Arm B patients received 8 cycles of lenalidomide plus low-dose dexamethasone (LD alone). Both arms received stem cell collection after 4 cycles of therapy if patients achieved at least a partial remission (PR). Patients with stable disease (SD) or progressive disease (PD) went off study. The primary objective was to compare best response. The secondary endpoints included duration of response (DOR), progression free survival (PFS), overall survival (OS) and evaluation of secondary malignancies in both arms. Results: From February 2008 to May 2011, 44 patients with newly diagnosed MM were randomized. The patient characteristics were as follow: median age of the patients was 61.7 years (range 48∼75), 45.5% female and 55.5% male patients, ISS stage I 31%, II 51% and III 18%. 40 patients were eligible for evaluation and 20 patients were randomized to Arm A or Arm B, respectively. The data were analyzed according to latest IMWG response criteria (Blood. 2011 May 5;117(18):4691–5). In an intention to treat analysis, patients in Arm A (LD + ASCT), achieved a 100% Overall Response Rate (ORR) with 40% PR (n=8) and 60% Very Good Partial Response (VGPR) (n=12). In Arm B (LD only) the ORR was 75% (n=15), including 15% CR (n=3), 35% VGPR (n=7), 25% PR (n=5), 20% SD (n=4) and 5% PD (n=1). The ORR was significantly superior in the LD+ASCT group compared to LD alone (p=0.047). After a median follow-up of 25.3 months, 17 patients have PD (8 in LD+ASCT and 9 in LD alone), 6 have died (1 in LD+ASCT and 5 in LD alone). DOR, PFS and OS were not significantly different in both groups. OS showed a trend to be superior in patients treated with LD+ASCT (p=0.08). (Table 1). One patient in the LD+ASCT arm developed MDS 13 months after start of therapy. Conclusion: Our interim analysis of an ongoing clinical study suggests that treatment of newly diagnosed MM patients with lenalidomide plus low-dose dexamethasone induction followed by upfront ASCT resulted in significantly improved ORR. There was no difference in terms of DOR or PFS with a trend of superior OS in the LD+ASCT group. The study requires careful interpretation based on the low patient number and relatively short follow up, but supports the continued role of upfront consolidative ASCT in newly diagnosed MM patients. The incidence of secondary malignancy was low with the development of 1 MDS. Updated data on response and overall survival will be available at the time of presentation.

Abstract Background: Peripheral T-Cell lymphomas (PTCLs) constitute approximately 10% of lymphoid malignancies and consist of several distinct entities based on pathologic and clinical characteristics. With the exception of a few subtypes (e.g., ALK-positive anaplastic large cell lymphoma (ALCL) and some primary cutaneous or leukemic forms of PTCL), a majority of PTCLs are aggressive as characterized by poor treatment response, rapid disease progression and poor overall survival. We have shown that landmark timepoints of event-free survival after diagnosis can stratify subsequent overall survival (OS) in diffuse large B-cell and follicular lymphoma. Here we evaluate this approach in newly diagnosed aggressive PTCLs treated with anthracyline-based or related chemotherapy. Methods. Newly diagnosed PTCL patients were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource (MER) from 2002-2012. Clinical data were abstracted from medical records using a standard protocol. For this analysis, we included patients receiving anthracycline-based or other multiagent chemotherapy for the following PTCL subtypes: ALK-negative ALCL (N=24); angioimmunoblastic T-cell lymphoma (AITL, N=34); PTCL, not otherwise specified (NOS; N=60); enteropathy-associated T-cell lymphoma (EATL, N=8); extranodal NK/T-cell lymphoma, nasal type (ENKTL, N=11); and hepatosplenic T-cell lymphoma (HSTCL, N=1). Patients were prospectively followed, and event-free survival (EFS) was defined as time from diagnosis to progression, re-treatment, or death due to any cause. Landmark EFS timepoints were assessed at 12 (EFS12) and 24 (EFS24) months after the date of diagnosis. Subsequent OS was defined as time from a specific endpoint (diagnosis, event or EFS landmark). Replication was performed in a population-based cohort of T-cell lymphomas diagnosed from 2000-2009 from the Swedish Lymphoma Registry. Results. 138 eligible patients were enrolled in the MER from 2002-2012, the median age at diagnosis was 58 years (range, 19-88), 66% were male, 73% had Stage III-IV disease, and 33% had IPI 0-1. At a median follow-up of 47 months (range 11-120), 87 patients (63%) had an event and 70 patients (51%) had died. From diagnosis, only 60 patients were event-free at 12 months (EFS12 45%). Patients who failed to achieve EFS12 had a poor subsequent OS from event (median OS = 6.8 months, 95% CI: 5.3-14.0, figure 1). In contrast, patients who achieved EFS12 had a favorable subsequent OS (median unreached, figure 2). Of the 427 eligible patients in the Swedish registry, the median age at diagnosis was 66 years (range, 18-88), 63% were male, 68% had Stage III-IV disease, and 25% had IPI 0-1. PTCL subtypes were: ALK-negative ALCL (N=89); AITL (N=80); PTCL, NOS (N=183); EATL (N=44); ENKTL (N=24); and HSTCL (N=7). At a median follow-up of 86 months (range 40-158), 333 patients (79%) had an event and 316 patients (74%) had died. From diagnosis, 183 patients were event-free at 12 months (EFS12 44%). Similar to the MER cohort, Swedish patients failing EFS12 had poor subsequent survival (median OS = 3.7 months, 95% CI: 2.9-5.3, figure 1). Swedish patients achieving EFS12 had a favorable subsequent OS (median OS = 89 months, figure 2). Similar results were obtained when conducting landmark analysis at 24 months after diagnosis (EFS24). Conclusion. Relapse and re-treatment events within the first 12 months of diagnosis are associated with very poor OS in PTCL treated with anthracyclines or related chemotherapy, while patients achieving EFS12 have encouraging subsequent OS. Stratifying patients into prognostically distinct subsets using EFS12 may help focus biologic and biomarker studies. EFS12 has potential as an early endpoint for studies of newly diagnosed PTCL. Further investigation of determinants related to post-EFS12 survival is needed. Disclosures Maurer: Kite Pharma: Research Funding. Cerhan:Kite Pharma: Research Funding.

Abstract Abstract 1343 Background: Multiple myeloma (MM) is the second most common hematological malignancy in the United States with an estimated 20,580 new cases in 2009. Over the past decade, the introduction of novel agents (thalidomide, lenalidomide and bortezomib) have played a pivotal role in improving response rates, duration of response, overall survival (OS) and quality of life. In this study we describe a single center experience with novel agents used for induction followed by high dose chemotherapy (HDT) and first autologous stem cell transplant (ASCT) in patients with MM. Method: A retrospective review of the medical records of 179 newly diagnosed patients with MM seen between October 2006 and December 2009 at The Ohio State University was performed. All patients received novel therapy containing thalidomide, bortezomib or lenalidomide as part of an induction regimen followed by ASCT. All patients received melphalan 140mg/m2 or 200mg/m2 as preparative regimen. Kaplan-Meier estimates were used to plot progression free survival and overall survival. Results: Of the 181 patients seen, 2 were excluded because they did not receive a novel agent as part of induction treatment. Of the 179 patients analyzed, median age was 56.8 years (29-80) with 30% of patients older than 60 years. African American represented 19%. Fifty-nine percent were male, 80% had Durie-Salmon (DS) stage III while 25%, 28%, 18% represented International prognostic score (IPS) stage I, II, and III respectively with 27% unknown. Median comorbidity index score was 2 (2-7) and median Karnofsky performance score (KPS) was 90% (70-100). Thirty percent had high risk genetic profile, and 73% received one line of treatment before ASCT. The median time from diagnosis to ASCT was 8.33 months (4-58). The overall response rate (ORR) prior to transplant was 84% (9% complete (CR), 29% very good partial (VGPR), and 46% partial (PR)). The ORR post ASCT was 89% (CR 45%, VGPR 22%, PR 21%). Non relapse mortality was 1% and 3% at 100 days and 1 year respectively. At a median follow up of 31 months (7-90), 69 patients (38%) had relapsed. Median progression free survival (PFS) was 29 months with 1 and 3 years PFS of 79.3% and 61.5% respectively (Fig. 1). The OS was not reached. One and 3 years OS were 93% and 88% respectively (Fig. 1). Univariate analysis showed that time to transplant > 12 months was associated with poor outcome and decreased overall survival (HR 3.30, p = 0.008). High risk genetic profile was also found to be associated with decreased overall survival although this was not statistically significant (HR 2.31, p = 0.070). Multivariate analysis found that only time to transplant > 12 months was an independent predictor of decreased OS. Significant predictors for disease progression were high risk genetic profile and time to transplant > 12 months in patients receiving 2 or more treatments before ASCT. Conclusion: Induction with novel agents followed by HDT and ASCT improves CR rate, in our case from 9% to 45%. Median PFS (29 months) was comparable to other published data. OS was not been reached after a median follow up of 31 months. Predictors of progression include high risk genetic profile and time to transplant > 12 months. The only significant predictor for survival was time to transplant. Our study suggests that an early transplant may improve OS and PFS. An extended analysis will be presented at the meeting.

Abstract Background: Acute promyelocytic leukemia (APL) accounts for approximately 10% of acute myeloid leukemia(AML) cases in adults. With the advent of targeted therapy like all- trans retinoic acid (ATRA) and arsenic trioxide, survival rates have improved leading to cure in majority of patients. The present study was designed to analyze the outcomes in newly diagnosed APL. Aims and objectives: The primary objective of this study was to analyze overall survival and relapse rate in APL. Secondary objective was to study the parameters impacting outcomes in APL. Materials and methods: All newly diagnosed patients with APL between January 2005 and December 2017 were retrospectively analyzed. Diagnosis of APL was confirmed by demonstration of PML-RARA translocation by polymerase chain reaction or fluorescence in situ hydridization. Risk stratification was done using Sanz risk. Event free survival was defined as the time from diagnosis till relapse, death or lost to follow up. Overall survival was defined as time from diagnosis till death or lost to follow up. Statistical analysis was done using SPSS software, v.25. Overall survival curves were plotted using the Kaplan-Meier method. INCLUSION CRITERIA: All cases of APL diagnosed by morphology and confirmed by RT PCR (PML RARα) were included in this study. EXCLUSION CRITERIA: Age ≤ 18yrs Death within 72 hours of admission / not taken treatment Prior chemotherapy or radiotherapy for the treatment of malignancy. Results: Data of 1396 AML patients between 2005 and 2017 was collected, of which 190(13.6%) patients had APL. Of 190 patients, 111 patients who met inclusion and exclusion criteria were analyzed. The median age at presentation was 33 years (range,19-60). The male female ratio was 1.01:1. The median duration of symptoms at presentation was 15 days (range, 3-180). According to Sanz risk grouping, high, intermediate and low risk were seen in 48 (43.1%), 46 (42.4%), 17(14.5%) patients respectively. The baseline characteristics are tabulated in Table 1. Of 111 patients, 96 (86.5%) patients received induction chemotherapy with ATRA and daunorubicin and 15(13.5%) patients received ATRA and arsenic trioxide. Induction mortality was 23(20.7%). Eighty-eight (79%) patients survived induction chemotherapy, of which 87(98.8%) were in complete molecular remission (CMR) at the end of consolidation. At a median follow up of 30 months, the event free survival rate, overall survival rate and relapse rate were 72%, 74.7% and 9% respectively. The overall survival rate in low-intermediate and high-risk groups were 84.1% and 62.5% respectively. Of eight patients who relapsed, five patients received second line chemotherapy and attained second CMR (100%). On univariate analysis, the strongest predictors for OS were high risk and bcr3 variant(p=0.007, p=<0.001 respectively). On multivariate analysis, only high risk was significant for overall survival (p=0.02). Conclusion: Majority of APL patients were high risk at presentation. High risk and bcr3 variant had significant impact on survival outcome in APL. As relapse rates were low and second CMR can be achieved with salvage chemotherapy in majority of patients, improving induction outcomes will further improve survivals in APL.

The proteasome degrades unneeded and damaged proteins. Tumor cells highly depend on increased protein production and their degradation suggesting that malignant cells with a high proliferation index will be more sensitive to proteasome inhibition. The addition of the proteasome inhibitor Bortezomib (Velcade, 'BTZ') to standard pediatric AML chemotherapy (cytarabine, daunorubicin and etoposide, 'ADE') depleted leukemia-initiating cells in a phase 2 clinical trial in pediatric AML (pedi-AML) patients. A randomized phase 3 clinical trial was then conducted by the Children's Oncology Group (COG) comparing ADE and ADE+BTZ treatment regimes in pedi-AML (AAML1031). To determine if there were specific protein expression profiles that correlated with response to BTZ-containing chemotherapy, we analyzed key components of the proteome of pedi-AML that participated in the trial using reverse phase protein arrays (RPPA). RPPA-based expression of 293 validated antibodies was tested in 500 leukemia samples and compared to expression in CD34+ samples from healthy individuals (n=30). Among all proteins, FOXO3 expression was identified as the protein with the highest influence on outcome in the ADE group. The expression of FOXO3 was prognostic for event-free survival (EFS) in both univariate (HR = 0.56, 95% CI = 0.34-0.90, P = 0.017) and multivariate (HR = 0.55, 95% CI = 0.34-0.88, P = 0.013) analysis. All patients were divided into two clusters (low and high) based on their FOXO3 expression level using median FOXO3 expression in normal CD34+. Kaplan-Meier survival analysis showed poor OS (3 year OS 65.3% vs. 73.9%, P = 0.03) and EFS (3 year EFS, 42.8% vs. 55%, P = 0.01) in low FOXO3 expressors (n=119) compared to patients with high FOXO3 expression (n=291) (fig. 1A). Notably, the poor prognostic effect of low FOXO3 for OS was seen in ADE (3 year OS 60% vs. 72.3%, P = 0.03), but not in ADE-BTZ (3 year OS 70.3% vs. 75.3%, P = 0.23) (fig. 1B). This suggests that in particular patients with low FOXO3 may be eligible candidates for BTZ-addition. To validate our findings, we performed knockdown (KD) of FOXO3 using a short hairpin approach in OCI-AML3 (p53WT) and THP-1 (p53null) cell lines. KD FOXO3 in OCI-AML3 had a short-term growth advantage compared to controls (Day 4, P = 0.004), but not KD FOXO3 THP-1 cells suggesting a role for p53 in the FOXO3 functional pathway. KD FOXO3 cells were more resistant to doxorubicin and etoposide combination therapy than controls (P = 0.04), confirming our clinical observations. Since therapeutic regimes in AML are currently shifting towards Bcl-2 inhibition by Venetoclax (ABT-199, 'ABT'), we were eager to test whether BTZ and ABT could act in synergy, and if this is related to FOXO3 expression. Single low dose BTZ and ABT did not reduce cell numbers after 3 days, but were effective when used in combination (<12% survival, P < 0.001) in OCI-AML3 and THP-1. Although cell counts were lower regardless FOXO3 status in both cell lines, flow cytometry analysis using Annexin V staining revealed significant more apoptosis in KD FOXO3 THP-1 compared to controls. Using RPPA-based profiling, we identified a cluster of pedi-AMLs that benefitted from BTZ-addition to standard therapy. We hypothesize that AML patients with low FOXO3 levels have less activation of their apoptotic transcriptional programs and that this subgroup may benefit from proteasome blockage to prevent FOXO3 proteasomal degradation. The use of FOXO3 as potential biomarker may identify a prognostically adverse cluster in pedi-AML that could stratify patients for ADE+BTZ therapy. Patients with low FOXO3 expression may potentially benefit from ADE+BTZ in combination with ABT, a novel and promising combination approach in AML that warrants further investigation. Figure 1. A. Kaplan meier analysis comparing overall survival (OS) and event-free survival (EFS) between low (n=119, blue) and high (n=291, red) FOXO3 expression in pedi-AML patients.

Abstract Abstract 1952 Poster Board I-975 Background: Vitamin D is a naturally occurring steroid hormone. In addition to its well-established role in maintaining serum calcium homeostasis, vitamin D has effects on cellular differentiation, proliferation, apoptosis, and angiogenesis. Vitamin D3 is naturally produced in skin in response ultraviolet-B (UVB) radiation from the sun. Several recent studies, however, have shown that a high proportion of community-dwelling subjects in both tropical and temperate climates are deficient in vitamin D, and that subjects in northern latitudes often require dietary supplementation to maintain vitamin D sufficiency. Further, several reports now suggest that vitamin D sufficiency is protective against the development of several cancers, including non-Hodgkin lymphoma (NHL). However, it is not known whether vitamin D impacts prognosis in diffuse large B-cell lymphoma (DLBCL), the most common NHL subtype. Methods: We evaluated serum vitamin D concentrations in two cohorts of DLBCL patients. The first cohort consisted of 374 patients newly diagnosed from September 2002-February 2008 who were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource, an observational study in which neither therapeutic nor diagnostic management is prescribed. All serum was obtained within 120 days of diagnosis, and was prior to treatment in 221 (59%). In the second study, 62 patients newly diagnosed from February 2006-August 2007 were enrolled on NCCTG clinical trial N0489, and all serum was obtained before the first course of therapy. Central pathology review was performed on all patients to confirm the diagnosis of DLBCL. Serum 25-hydroxyvitamin (25-OH-VitD) levels were measured by the gold standard method for vitamin D determination: liquid chromatography tandem mass spectroscopy (LC-MS/MS). Vitamin D deficiency was defined as total serum 25-OH-VitD < 25 ng/mL (62.5 nmol/L). SPORE patients were followed per a standard protocol for event-free (progression, retreatment, or death due to any cause) and overall survival (EFS and OS, respectively); N0489 patients were followed in a similar way per the clinical trial protocol. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CI). Results: SPORE patients were primarily treated with immunochemotherapy (83%); all N0489 patients were treated with epratuzumab + R-CHOP21. The median age at diagnosis was 62 years (range, 19-93) for SPORE patients and 61 years (range, 21-82) for N0489 patients. Median follow-up for SPORE patients was 36 months (range, 1-77) with 95 deaths and 131 events; median follow-up for N0489 patients was 24 months (range, 7-39) with 13 deaths and 18 events. Vitamin D deficiency was identified in 188 SPORE patients (50%) and 15 N0489 patients (24%). There were no differences in the prevalence of vitamin D deficiency by age, IPI, or whether serum was obtained prior to starting treatment (all p > 0.28). Vitamin D deficiency was associated with inferior overall (HR=2.33, 95% CI 1.53-3.57, logrank p = 0.0001) and event-free survival (HR=1.71, 95% CI 1.20-2.44, logrank p = 0.003) in the SPORE cohort. These associations remained significant after adjusting for IPI and treatment: OS HR=1.97, 95% CI 1.27-3.07; EFS HR=1.47, 95% CI 1.02-2.21. These results were similar for the subset of SPORE patients who were treated with R-CHOP. The HRs for vitamin D deficiency and event-free survival were consistent in the N0489 patients (HR=1.63, 95% CI 0.61-4.35, IPI adjusted HR=1.43, 95% CI 0.53-3.85), although these results lacked precision due to a smaller sample size. We were unable to evaluate OS in N0489 due to the small number of deaths. Conclusions: Approximately 50% of all DLBCL patients in this northern US latitude population are vitamin D deficient at the time of diagnosis and treatment. Vitamin D deficient patients have an inferior event-free and overall survival compared to patients with vitamin D levels within the normal range. Vitamin D supplementation during treatment of DLBCL patients with vitamin D deficiency should be evaluated in a clinical trial setting. Disclosures: No relevant conflicts of interest to declare.

e19005 Background: CALGB 10403 is a pediatric-inspired ALL regimen that has recently been shown to have improved survival rates in adolescents and young adults with ALL when compared to historical outcomes with traditional adult ALL regimens (Stock et. al, 2019). Methods: This is a retrospective cohort study of ALL patients who received induction CALGB 10403 at Stanford University (both on and off trial), achieved CR1, and subsequently relapsed. Primary outcome of interest was event free survival from time of diagnosis. Events were defined as relapse or death. Secondary outcomes were overall survival and event free survival from first relapse. Patients were censored at time of last clinical follow up. Results: 25 patients met inclusion criteria and received front-line CALGB 10403 from April 2010 to September 2018. At the time of initial diagnosis median age was 30 years (range 18 – 39 years). 68% of patients were male. 48% of patients were overweight and 40% were obese. 76% of patients had precursor B cell ALL while 24% had T cell ALL. 12% had CNS disease at diagnosis. 36% of patients had WBC greater than 30k. 12% of patients had CRLF2 rearrangement. 12% of patients were MRD positive after first induction. 20% of patients received rituximab. Median event free survival time from diagnosis was 20 months (range 3 – 79 months) and median overall survival time was 53 months. Blinatumomab was the most common salvage therapy after 1st relapse, followed by inotuzumab. 15 patients (60%) achieved CR2, of which 4 (27%) were MRD positive after 2nd induction. 15 patients (60%) went to HSCT. Of the patients who achieved CR2, 8 relapsed for a second time. Median event free survival time after first relapse was 23 months. Survival 1 year after relapse was 60%. 11 of the 25 patients were alive at last follow up. Median follow up time of survivors was 6 years. Conclusions: This is a descriptive retrospective cohort study of adult patients in a real world setting who received CALGB 10403 induction and subsequently relapsed. Compared to other studies of relapsed ALL patients who were induced with traditional chemotherapy (Fielding et. al, 2007), survival 1 year after relapse was much higher (60% vs. 22%). As CALGB 10403 becomes an increasingly common induction regimen for AYA and adults with ALL, further outcomes study is required.[Table: see text]

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.
