Abstract Abstract 3017 Introduction: Multiple myeloma (MM) is a malignancy of clonal plasma cells with resulting in an increase production of ineffective immunoglobulins with suppression of non-involved immunoglobulins. Patients with MM are at increased risk of infectious complications, particularly to those organisms in which opsonization is one of the key defense mechanisms, e.g. strep and staph infections. Treatment of MM is virtually always associated with further immunosuppression, at least in the immediate term, until the malignant clone is eradicated and normal immunoglobulins are produced. Rationale: Due to further compromise of an already incompetent immune system by initial chemotherapy and the previous suggestion (Oken et al Am J Med 1996; 100:624-628) that prophylactic antibiotics may reduce infectious complications, this study was designed to evaluate the impact of prophylactic antibiotics on the incidence of serious bacterial infections during the first two months of treatment. Methods: Pts with untreated MM receiving chemotherapy were randomized on a 1:1:1 basis to receive either a daily ciprofloxacin (C; 500 mg), trimetheprim-sulfamethoxazole (T; DS bid) or observation (O) for the first 2 months of treatment. Pts were evaluated for serious bacterial infection (grade 3 or 4) during the first two months of myelotoxic/suppressive therapy. Secondary endpoints (EP) included: incidence of non-bacterial infections, resistant organisms due to prophylaxis, the incidence of infection the third month OFF of antibiotic prophylaxis and whether protection against infection is associated with an improved response rate. Results: From July 1998 to January 2008, 212 untreated, symptomatic MM pts being treated with myelotoxic/suppressive chemotherapy were randomized to C (n=69), T (n=76) or O (n=67) for the first 2 months of treatment. The incidence of serious infection (> grade 3 ECOG toxicity criteria and/or hospitalization) was comparable among groups: C=10 (14.7%), T=5 (6.9%), O=9 (14.5%); p= 0.268 which was the primary EP. The incidence of any infection during the first 2 months was also comparable (20% vs 23% vs 22%, respectively, p=0.910). There were 25 grade 2 infections and 4 grade 3 infections involving respiratory (n =13), sepsis/bacteremia (n = 4), and urinary (n =3), joint/bone (n =2), unknown (n =2) or various GI tract (n = 5) and skin (n =1). Eight pts expired within the first 2 months: 2 from MM, 3 cardiac, 2 respiratory, 1 renal (unrelated to MM or Rx) occurring in the C (4), T (1), O (2). Secondary EPs failed to show a difference in the incidence of serious bacterial infection during the third month in the absence of prophylaxis (C=3%, T=4%, O=2%; p=0.874), development of resistant infections, initial response to therapy or overall survival. Conclusions: The use of prophylactic antibiotics did not decrease the incidence of serious infection (> grade 3 and/or hospitalization) nor of any infection within the first 2 months of treatment. Infection prophylaxis did not affect the incidence of infection upon completion of 2 months of therapy (nor, ultimately, at any time during the subsequent 2 years), the response to therapy or to overall survival. Incidentally, there were no documented cases of PCP despite the assumption that MM pts, with compromised immune systems, are more susceptible. The incidence of serious infections in this study, in which few patients received novel agents, is comparable to that observed in more modern regimens even in the presence of mandated/recommended prophylactic antibiotics. Utilizing either lenalidomide plus dexamethasone or clarithromycin, lenalidomide and dexamethasone resulted in > grade 3 infectious complications in 16.7% and 9.7%, respectively, as reported by the Mayo Clinic and Cornell groups, respectively (Gay et al Am J Hematol, in press). Furthermore, in the ECOG E4A03 randomized trial of lenalidomide plus either high dose dexamethasone (LD) or low dose dexamethasone (Ld) in which prophylactic antibiotics were recommended, the incidence of > grade 3 infectious complications were 9.4% and 6.4%, respectively (Rajkumar et al Lancet Oncol 2010; 11: 29–37). We conclude that routine use of prophylactic antibiotics should not be mandated for patients receiving induction chemotherapy. Prophylactic antibiotics should be considered on a case-by-case basis after analyzing the potential infection risk in individuals. Disclosures: No relevant conflicts of interest to declare.

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.

Infusion Protocol

Purpose Daratumumab is the first anti-CD38 monoclonal antibody of the class approved for recurrent and refractory multiple myeloma. Grade 3 and 4 Infusion-Related Reactions (IRRs) are frequent during the first and second infusions. Due to the risks associated with severe IRRs, daratumumab is systematically administered over a period of 3.5 hours. The main objective of this study was to evaluate the safety of a 90-minute daratumumab infusion from the third infusion. Patients and methods All patients who had received two or more doses of daratumumab in monotherapy or in combination with standard infusion rates were included. We excluded patients enrolled in clinical trials. For the rapid infusion protocol, 20% of the dose was administered over 30 minutes and the remaining 80% over 60 minutes. Results From April 1 to May 31, 2019, 25 patients received 53 90-minute infusions of daratumumab. Premedication included corticosteroids, antipyretics, antihistamines, and if necessary a leukotriene receptor antagonist. No grade 3 or grade 4 IRRs were observed. Conclusion From the third infusion, we found that a rapid administration of daratumumab (90 vs 210 minutes) was well tolerated and safe. It would be interesting to test this regimen from the second infusion.

Objective. To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM) patients with the therapy of subcutaneous (subQ) administration of bortezomib and dexamethasone plus thalidomide (VTD) regimen.Methods. A total of 60 newly diagnosed MM patients were analyzed. 30 patients received improved VTD regimen (improved VTD group) with the subQ injection of bortezomib and the other 30 patients received conventional VTD regimen (VTD group).The efficacy and safety of two groups were analyzed retrospectively.Results. The overall remission (OR) after eight cycles of treatment was 73.3% in the VTD group and 76.7% in the improved VTD group (P>0.05). No significant differences in time to 1-year estimate of overall survival (72% versus 75%,P=0.848) and progression-free survival (median 22 months versus 25 months;P=0.725) between two groups. The main toxicities related to therapy were leukopenia, neutropenia, thrombocytopenia, asthenia, fatigue, and renal and urinary disorders. Grade 3 and higher adverse events were significantly less common in the improved VTD group (50%) than VTD group (80%,P=0.015).Conclusions. The improved VTD regimen by changing bortezomib from intravenous administration to subcutaneous injection has noninferior efficacy to standard VTD regimen, with an improved safety profile and reduced adverse events.

Abstract Background Multiple myeloma (MM) is a heterogeneous condition with variable disease course, response to therapy, and survival outcome. Cytogenetics and fluorescent in-situ hybridization (FISH) have identified several recurrent chromosomal aberrations in MM and play important and independent roles in risk stratification (Munshi et al. Blood 2011). However, the pathogenesis of the disorder remains poorly understood. Next-generation sequencing has recently identified that MM involves mutations of genes with roles in protein translation, histone methylation, and blood coagulation (Chapman et al. Nature 2011). Based on the observation that extra copies of MLL, a histone methyltransferase known to regulate the homeotic transcription factor HOXA9 that is highly expressed in MM, is frequently detected in MM, we sought to define the incidence and prognostic significance of excess MLL in MM patients. Methods We identified 188 patients with newly diagnosed MM who had cytogenetics and/or FISH performed on initial, pre-treatment bone marrow specimens at Memorial Sloan-Kettering Cancer Center between January 2009 and December 2012. Standard karyotype and FISH were performed as previously described (Cigudosa et al. Blood 1998, Gerritsen et al. Blood 1992). Probes included LSI IgH/FGF3, LSI IgH/CCND1, LSI IgH/MAF, LSI MLL, LSI p53/cep17, LSI13q14.3/13q34, LSI ETV6, LSI CBFB, LSI 1p36/1q25, and LSI 5,9,15 from Abbott Molecular. Fisher's exact test evaluated the association between MLL and selected abnormalities. Kaplan-Meier methodology estimated overall survival from the date of BM evaluation, and survival was compared using a logrank test. Results In unselected bone marrow specimens, abnormalities were detected by karyotype in 17% (27/156) and FISH in 47% (87/186) of patients tested. Hyperdiploidy, which has been associated with longer survival, was identified in 23% (43/187) of patients, while the unfavorable risk abnormalities, including loss of p53, deletion 13q (by karyotype), translocation (4;14) and excess 1q were seen in 8% (15/179), 8% (12/156), 4% (7/176) and 16% (29/178) of patients, respectively. Translocation (11;14) was seen in 4 patients; translocation (14;16) was not identified in any patient. 28% (51/183) of patients had extra copies of MLL, which was the most frequent genetic abnormality identified. Unexpectedly, this abnormality was significantly associated with both favorable (hyperdiploidy, P = <0.001) and unfavorable (deletion 13q, P = 0.043; excess 1q P = 0.001) risk genetics. While having excess MLL had no impact on the overall survival of standard-risk patients, defined as neither hyperdiploid nor with unfavorable genetics (N = 100), patients with poor-risk genetics (N = 46) and extra copies of MLL had a trend toward better survival, P = 0.06 (Figure 1). Conclusions Karyotype and FISH studies identified excess MLL as the most frequent cytogenetic abnormality in a large cohort of newly diagnosed MM patients. In patients with MM and unfavorable cytogenetics, the presence of excess MLL may ameliorate some of the adverse impact of associated with these abnormalities. Understanding the functional significance of excess MLL, perhaps as it relates to frequently dysregulated HOXA9 in MM, may provide insight into disease pathogenesis and/or identify drugable targets.

Abstract Bortezomib is a targeted proteosome inhibitor licensed & approved for in multiple myeloma both as first line and in relapsed setting. This is a retrospective non experimental cross sectional quantitative comparative group study using clinical case notes, laboratory & pharmacy records for patients treated with Bortezomib in 2011 & 2012. Outcomes studied included remission status, adverse events, progression free survival and overall survival at follow up. The study also looked at the comparative responses of cohort of patients administered Bortezomib through intravenous & subcutaneous route. The cohort consisted of 33 patients, 21 male, 11 female, median age 71 years, first line 10 patients, second line 23 , median number of cycles in 2011 & 2012 – first line 3 & 8 , second line 5 & 4, respectively. In 2011, 8 received intravenous treatment, 9 were switched from intravenous to subcutaneous route whilst all patients from 2012 received subcutaneous Bortezomib. The most frequently used regimen was Bortezomib Dexamethasone ( VD). The overall response rate ( ORR >/= Minor Response) was: First line 70% (7/10) ; Second line 47.8% ( 11/23); median PFS ( Figure 1) 6 months ( First line: 7 months ; Second line : 6 months) and median overall survival ( Figure 2) at follow up: 9 months ; 39.4 % ( 13/33) First line 8.5 months, Second line 11 months. Subcutaneous Bortezomib was equivalent to intravenous Bortezomib in terms of efficacy & tolerance. Of 33 patients, there were 12 dose reductions. Adverse events reported included: peripheral Neuropathy - grade 3 - 6% ( all grades 27.3%); Diarrhoea - grade 3 - 3% (all grades 6%); Nausea / Vomiting - grade 3 - 3% ( all grades 6%) and Second Primary Malignancies - 12% ( 4 of 33). Mortality at follow up was 20 patients from cohort of 33 ; causes included disease progression in 11, second primary malignancy with disease progression in 4, COPD 2, Systemic Amyloidosis 2, Tuberculosis 1 , Multiple co morbidities 1 and Asthma with mechanical failure in single patient. Second primary malignancies ( 4/33) included Prostate carcinoma ( 1), Renal Cell Carcinoma (1), Neuroendocrine tumour ( 1 ) and Unknown Primary in single patient. Beyond second line treatment, majority (14 of 23 patients; 60.9 %) did not have further active treatment. These data indicate that patient outcomes were modest compared to published data from VISTA and APEX trials. Majority of patients did not have further active treatment beyond second line which suggests the most effective treatment strategy should be used upfront as patients may not be fit to have further lines of therapy despite availability of recently introduced novel targeted agents. A higher percentage of second primary malignancies were noticed in this cohort which should be an area of further clinical research.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

7521 Background: Lenalidomide is a novel, orally administered, immunomodulatory drug (IMiD) that has single-agent activity against MM and additive effects when combined with dexamethasone (Dex). Methods: In this phase 3, multicenter, double-blind trial, 354 patients (pts)with relapsed or refractory MM were treated with Dex 40 mg daily on days 1–4, 9–12, 17–20 every 28 days and were randomized to receive either lenalidomide (Len) 25 mg daily orally on days 1–21 every 28 days or placebo. Beginning with cycle 5, Dex was reduced to 40 mg daily on days 1–4 only, every 28 days. Patients were stratified with respect to B2M (≤ 2.5 vs. > 2.5 mg/mL), prior stem cell transplant (none vs. ≥ 1), and number of prior regimens (1 vs > 1). The treatment arms were well balanced for prognostic features. Results: The overall response rate was greater with Len-Dex than with Dex-placebo (59.4% vs. 21.1%; p < 0.001). Complete responses were achieved in 12.9% of pts treated with Len-Dex and 0.6% of pts treated with Dex-placebo. The median time to progression (TTP) for pts treated with Len-Dex was 11.1 months compared to 4.7 months for pts treated with Dex-placebo (p < 0.000001). Median overall survival was higher with Len-Dex (not reached) compared to Dex-placebo (24 months) (hazard ratio 1.76, p = .0125). Grade 3–4 neutropenia was more frequent with combination therapy than with Dex-placebo (24% vs. 3.5%), however ≥ grade 3 infections were similar in both groups. Thromboembolic events occurred in 15% of pts treated with Len-Dex and in 3.5% of pts treated with Dex-placebo. Atrial fibrillation occurred in 8 pts and CHF developed in 4 pts treated with Len-Dex. Conclusions: Considering the ease of oral administration, higher response rate, longer time to progression and overall survival benefit, the combination of lenalidomide-dexamethasone may very well represent the treatment of choice for early refractory or relapsing multiple myeloma. The relatively infrequent side effects should not detract from these improvements, but the use of prophylactic antithrombotic therapy should be considered for patients treated with the combination of lenalidomide and dexamethasone.

Abstract Abstract 1856 Background: Lenalidomide has proven to be a highly effective treatment in relapsed multiple myeloma (MM), particularly when used in combination with dexamethasone. However, over 30% of patients with myeloma have renal insufficiency and as lenalidomide is renally excreted, little information is available about its use in myeloma patients with impaired kidney function. Defining a safe and effective dose of lenalidomide in this context is critical. Objective: We undertook this study to establish the maximum tolerated dose of lenalidomide in three cohorts of patients with different levels of impaired renal function: Group A - patients with creatinine clearance (CrCl) between 30 and 60 mL/min, Group B - patients with CrCl <30 mL/min not on dialysis, and Group C - patients with CrCl < 30mL/min who are on dialysis. Secondary endpoints included response rate, progression free survival and overall survival. Methods: Eligible patients had previously treated MM with renal impairment defined as creatinine clearance < 60 mL/min measured within 21 days prior to registration. Patients previously treated with lenalidomide were required to demonstrate clinical response (any duration) or stable disease with progression-free interval of > 6 months from start of that therapy. All patients received dexamethasone 40 mg orally on days 1, 8, 15 and 22 of a 28-day cycle. Prophylactic anticoagulation consisted of either 81 mg or 325 mg per day of aspirin. Patients also received lenalidomide orally every 1 or 2 days on days 1 through 21 of a 28-day cycle, as described below (Table 1). Starting doses were as in US Product Insert. Dose escalation follows a standard 3+3 design. Results: There have been 23 patients enrolled into groups and cohorts as shown in Table 1. Median age was 73 (range 49–89) and 13 (57%) were women. ISS stage was advanced in all patients, 0 in stage 1, 4 (18%) in stage 2 and 19 (82%) in stage 3. The regimen was well tolerated. Indeed, the MTD has not been reached in any of the groups, as no DLTs have occurred to date. The most commonly reported clinical adverse events (all grades, independent of attribution) across all patients included infections, hyperglycemia, constipation, dizziness, hyponatremia, hypocalcemia and tremor. Hematological toxicities (grade 3–4) occurred in 13 out of 21 pts (62%), mostly neutropenia and thrombocytopenia. Grade 3–4 events at least possibly related to the regimen occurred in 70% and included pneumonia (26%) and otitis media (9%). Response was seen in 14 patients, resulting in an overall response rate of 61%. CR was seen in 1 patient (4%), VGPR in 2 patients (9%), PR in 11 patients (43%), and SD for 9 patients. With median follow-up of 15.5 months, median progression-free survival is 9.8 months and median overall survival is 22 months. Conclusion: Lenalidomide and dexamethasone is a safe and effective regimen in patients with multiple myeloma and renal insufficiency. It is also very well tolerated, although cytopenias are common but manageable. MTD has yet to be reached in each group, allowing for higher doses to be given than previously thought, including 25mg daily (for 21/28 days) in patients with CrCl 30–60 mL/min, 25 mg every other day (for 21/28 days) in patients with CrCl < 30 mL/min not on dialysis, and 10mg daily (for 21/28 days) in patients with CrCl < 30 mL/min on dialysis. These results will provide needed, clinically relevant dosing for lenalidomide in MM patients with renal insufficiency.

PURPOSE: This updated analysis examined survival outcomes after 60 months of follow-up in patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM) treated with the 3-drug regimen of modified lenalidomide-bortezomib-dexamethasone (RVD lite) in this population. METHODS: RVD lite was administered over a 35-day cycle. Lenalidomide 15 mg was given orally days 1-21; bortezomib 1.3 mg/m2 once weekly subcutaneously (SC) on days 1, 8, 15, and 22; dexamethasone 20 mg orally day of and after bortezomib for 9 cycles followed by 6 cycles of consolidation. Eligibility requirements included ECOG performance status ≤ 2 and acceptable hepatic, renal, and hematologic function. Primary objective was to evaluate overall response rate (ORR). Secondary objectives included evaluation of safety, progression free survival (PFS), overall survival (OS), and the pharmacokinetic (PK) profile of intravenous (IV) and SC bortezomib. RESULTS: Fifty-three eligible patients enrolled between 4/17/13 and 7/25/15; 50 received at least one dose of therapy. As previously reported, the median age at study entry was 72 years (range 65-91). ISS stage was I in 19 (38%), II in 17 (34%), and III in 14 (28%) pts. Fatigue was the most commonly reported toxicity occurring in 37 (74%) and was mostly grade 1 or 2 in 29 (58%). Other grade 3 or greater toxicities included hypophosphatemia in 17 (34%), neutropenia in 7 (14%), and rash in 5 (10%) pts. Low grade peripheral neuropathy was reported in 31 (62%) patients with only 1 patient experiencing grade 3 symptoms. There were statistically significant improvements in scores of physical functioning (p=0.013), future perspective (p=0.023) and disease symptoms (p=0.001). Patients reported fewer symptoms across all symptom domains with the exception of diarrhea. The ORR was 86% and 66% of patients achieved a very good partial response (VGPR) or better. The median time to response was 1.1 months. At a follow-up of 61 months, median PFS was 41.9 months (95% CI, 31.2 - ∞) and median OS not reached. The 5-year overall survival was 61.3%. Sixty-six percent of patients received lenalidomide maintenance. CONCLUSIONS: RVD lite is a well-tolerated and highly effective regimen in the transplant-ineligible population with robust PFS and OS. Our data demonstrate that the benefits of more effective combination strategies observed in younger, fitter, transplant-eligible patients can be effectively used in older, transplant-ineligible patients with modifications in dose and schedule, without compromising efficacy.
