Abstract Introduction: A recent study revealed an antiproliferative and apoptotic effect of propranolol on multiple myeloma (MM) cells. Our previous small matched case-control study showed longer survival in patients with propranolol and other beta-blockers (BB) intake than those without. This larger scale study was conducted to confirm the positive association of BB and MM survival. Methods: We identified 1971 newly diagnosed pts seen at Mayo Clinic between 1995 and 2010. Cardiac medication usage after diagnosis of MM was extracted from patient records and categorized based on BB intake. Cause of death was collected with death due to MM as the primary interest event and death due to cardiac disease or other reasons as competing risk events. The primary outcomes were MM disease-specific survival (DSS) and overall survival (OS). Cumulative incidence functions and Kaplan-Meier method were used to estimate the 5-year cumulative incidence rate (CIR) of MM death and OS rate, respectively. DSS and OS were compared by Gray's test and log-rank test, respectively. Multivarable Cox proportional hazard models were used to estimate the adjusted cause-specific HR (HRCSadj.) and hazard ratio (HRadj.) for DSS and OS, respectively, adjusting for demographics, disease characteristics, diagnosis year, and various chemotherapies. Results: 930 (47.2%) of MM patients had no intake of any cardiac medications; 260 (13.2%) had BB only; 343 (17.4%) used both BB / non-BB cardiac medications; and 438 patients (22.2%) had non-BB cardiac drugs. Five-year CIR of MM death and OS rate were shown in table. Superior MM DSS was observed for BB only users, compared to patients without any cardiac drugs (HRCSadj., .53, 95% confidence interval [CI], .42-.67, padj.<.0001) and non-BB cardiac drugs users (HRCSadj., .49, 95% CI, .38-.63, padj.<.0001). Patients received both BB and other cardiac drugs also showed superior MM DSS than non-cardiac drugs users (HRCSadj.., .54, 95% CI, .44-.67, padj.<.0001) and non-BB cardiac drug users. (HRCSadj., .50, 95% CI, .40-.62, padj.<.0001). MM DSS does not differ between BB users with and without other cardiac drugs (padj.=0.90). Multivariable analysis showed the same pattern for OS. None of the MM therapies impacted the differences in DSS and OS among BB intake groups (interaction padj.>.60). Conclusion: MM patients with BB intake showed reduced risk of death due to MM and overall mortality compared to patients who used non-BB cardiac or never used cardiac drugs. The result warrants further investigation for anti-cancer effect of BB in MM. Disclosures Shi: Mayo Clinic: Employment.

Improve Risk Stratification

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 1244 Background. Voriconazole (V) treatment has been shown to improve the 12 week (W) survival rate of hematological patients (pts) with invasive aspergillosis (IA), including recipients of allogeneic hematopoietic stem cell transplants (HSCT). We investigated whether this early survival advantage could translate into a significant increase in overall survival. Methods. We retrospectively reviewed all consecutive pts who received a transplant between Sept. 1997 and Dec. 2008 at Saint-Louis Hospital and were diagnosed as having IA. The temporal origin of the study was the date of IA diagnosis for each patient. Factors associated with survival were analyzed using Cox proportional hazard models. Separate models were estimated for survival up to 12 W and for survival between 12 W and 24 months (M) in pts surviving longer than 12 W. The deaths of pts with and without IA were analyzed with a competing risk framework. Cumulative incidence curves were compared using Gray's tests. Results. Our study examined 89 IA pts. The median follow-up was 70 M (range, 11–130 M). Two pts did not receive any antifungal treatment and were excluded from subsequent analyses. Of the 87 pts, 42 received first-line V and 45 primarily received a lipid formulation of amphotericin B (n=25), amphotericin B deoxycholate (n=10), caspofungin (n=8) or itraconazole (n=2). The primary characteristics of pts with IA and their causes of death, separated by V as first-line treatment, are shown in the table below. The median survival was 2.6 M, and the overall survival at 24 M was 19% (95% CI 12–30 M) (see figure). Overall, the survival rates of the two groups were significantly different (P= 0.010). However, the differences in survival were quite dramatic prior to 10 M, whereas both survival curves became very close after one year. At 18 M, the numbers of surviving pts were almost identical in the two groups [19% (95% CI: 11–34%) in pts who did not receive V as first-line treatment vs. 21% (95% CI 11–38%) in pts who did]. Pts who did not receive V as a first-line treatment displayed a higher probability of dying from IA than those who did (P=0.004), whereas opposite results were found for mortality in pts without IA (P=0.006). The 24-M cumulative incidence of death from IA was 47% (95% CI 31–61%) in the no V group and 19% (95% CI 9–33%) in the group treated with V. The 24-M cumulative incidence of death in pts without IA was 4% (95% CI 7–14%) in the no V group and 27% (95% CI 14–42%) in pts treated with V. The probability of death from another cause, with IA, was similar in both groups (29% vs. 36% at 24 M; P=0.46). After adjusting for donor type, conditioning regimen, progressive GVHD at diagnosis of IA and cumulated steroid dose (mg/kg) in the W preceding IA diagnosis, administration of V as first-line treatment was found to decrease the risk of death during the first 12 W by approximately 70% [HR=0.31 (95% CI 0.16–0.60); P=0.0005]. Conversely, analysis of mortality between 12 W and 24 M failed to identify any significant predictor of risk of death; however, only 24 pts died during this period. Conclusions. The finding that first-line treatment with V, which is associated with a tremendous improvement in IA outcome, does not translate into an increase in overall survival (even in the context of early diagnosis) is striking. Diagnosis of IA following HSCT, whatever the outcome, appears to be a strong marker for poor long-term prognosis.

Triplet Regimen

Abstract Introduction: Triplet therapies are used for treatment (Tx) of both transplant-eligible and -ineligible patients (pts) with newly diagnosed multiple myeloma (NDMM). Actual patterns and outcomes of Tx are not fully understood. Connect MM® is the first and largest multicenter, US-based, prospective observational cohort study designed to characterize Tx patterns and outcomes for pts with NDMM. This analysis describes demographic and disease characteristics of pts who received triplet Tx as an induction regimen and for whom transplant was or was not intended. The analysis explores the relationship of these factors with overall survival (OS) and other efficacy endpoints. Patients and Methods: Pts aged ≥ 18 y with NDMM within 60 days of diagnosis were eligible for enrollment regardless of disease severity, medical history, or comorbidities. Data including transplant intent (yes/no) was collected at baseline; follow-up data was collected quarterly thereafter. Based on the initial intent, 2 groups were identified: patients with intent to transplant who received transplant (TT) and pts with no intent to transplant who did not receive a transplant (NT). Triplet Tx was defined as the combination of ≥ 3 concurrent therapeutic agents in the first course of Tx (within 56 days of study entry). KM analysis adjusted for age was conducted for OS. Because decisions on use of transplant and triplet therapy are influenced by multiple factors, a multivariable Cox regression analysis was performed to evaluate the contribution of the triplet therapy (yes/no) to OS and was adjusted for other variables, including age, comorbidities, and ISS staging. Results: Between September 2009 and December 2011, 1493 pts were enrolled. This analysis was on 1436 pts: 650 pts with transplant intent and 786 pts without transplant intent. The data cutoff date was November 30, 2014, and the median follow-up for overall survival (OS) was 33.8 mos. Of pts with transplant intent, 451 (69%) received transplant (TT) and 199 (31%) did not. Of pts without transplant intent, 62 (8%) received transplant and 724 (92%) did not (NT). The abstract focuses on TT and NT groups only. NT pts tended to be older and have more advanced ISS staging and higher β2-microglobulin levels than TT pts (Table). The most common triplet regimen given during the first course treatment (within 56 days) was lenalidomide, bortezomib, and dexamethasone (RVd). RVd was administered to 34% of the NT pts (76/225) and 59% of the TT pts (152/257). The most common non-triplet regimen was bortezomib and dexamethasone (Vd), which was given to 31% of NT pts (156/499) and 38% of TT pts (73/194). Within the NT group, pts given triplet Tx had a lower risk of death than those who did not receive triplet Tx (P = .0013). The multivariable analysis found triplet Tx to be associated with a 36% reduced risk of death (hazard ratio [HR] = 0.64 [95% CI, 0.50-0.82]; P = .001). ISS disease stage (HR = 1.43 [95% CI, 1.21-1.69]; P < .001) and history of diabetes (HR = 1.38 [95% CI, 1.08-1.78]; P = .012) were negative prognostic factors for OS. Within the TT group, pts who received triplet Tx did not attain an OS benefit (P = .8993), and no baseline characteristics were significantly associated with OS. These results may be limited by other factors not considered that may have influenced physicians' choice of treatment, including the use of maintenance therapy and a short follow-up period of 33.8 months. Conclusions: Triplet Tx as a first regimen is associated with longer OS in pts without transplant intent who did not receive a transplant. RVd and Vd were the most common first Tx regimens, respectively. Continued follow-up of these pts and enrollment of an additional cohort will provide additional data with mature follow-up. Table 1.

Abstract We retrospectively reviewed all patients receiving bortezomib, lenalidomide and dexamethasone induction followed by autologous stem cell transplantation (ASCT) within 12 months of diagnosis for multiple myeloma at the Mayo Clinic. 243 patients treated between January 2010 and April of 2017 were included in the study. Median age was 61 (interquartile range, 55-67) with 62% of patients being male. High risk cytogenetic abnormalities (HRA) were present in 34% of patients. 166 (68%) patients received some form of maintenance/other therapy post transplant (no maintenance (NM, n=77), lenalidomide maintenance (LM, n=108), bortezomib maintenance (BM, n=39) and other therapy (OT, n=19)). Overall response rate was 99% with complete response (CR) rate of 42% and 62% at day 100 and time of best response post transplant respectively. The four cohorts categorized by post transplant therapy were well matched for age, gender and ISS stage. HRA were more common amongst patients receiving bortezomib maintenance or other therapy post transplant (NM 18% vs LM 22% vs BM 68% vs OT 79%, p<0.0001). Two year and five year overall survival rates were 90% and 67% respectively with an estimated median overall survival (OS) and progression free survival (PFS) of 96 months and 28 months respectively for the whole cohort. OS was not significantly different when stratified by post-transplant therapy (Median OS 96 months for NM vs not reached for LM vs 62 months for BM vs not reached for OT, p=0.61), however post-transplant therapy was predictive of PFS (median PFS 23 months for NM vs 34 months for LM vs 28 months for BM vs 76 months for OT, p=0.01). High risk cytogenetics was associated with a worse OS but not PFS when compared to patients with standard risk (median OS: not reached for standard risk vs 60 months for HRA, p=0.0006; median PFS: 27 months for standard risk vs 22 months for HRA, p=0.70). In patients that did not receive maintenance therapy presence of HRA was a strong predictor of OS and PFS (median OS: not reached for standard risk vs 36 months for HRA, p<0.0001; median PFS: 24 months for standard risk vs 7 months for HRA, p<0.0001). Patients receiving maintenance therapy appeared to have a similar PFS and OS irrespective of cytogenetics (median OS: not reached for standard risk vs 62 months for HRA, p=0.14; median PFS: 35 months for standard risk vs 34 months for HRA, p=0.79).On multivariable analysis ISS stage III and achieving CR/stringent CR predicted PFS whilst the only independent predictors of OS were presence of HRA and achieving CR/stringent CR. The combination of bortezomib, lenalidomide and dexamethasone followed by ASCT is a highly effective regimen producing deep and durable responses in many patients. Maintenance therapy in this cohort may overcome the poor prognostic impact of high risk cytogenetic abnormalities. Table Table.

Abstract Abstract 3859 Poster Board III-795 The initial results of the pivotal, international, phase III VISTA trial demonstrated the superiority of bortezomib (Velcade®) plus melphalan–prednisone (VMP) versus MP alone across all efficacy end points, including overall survival (OS), in previously untreated multiple myeloma (MM) patients ineligible for high-dose therapy (San Miguel et al, N Engl J Med 2008). We conducted a planned updated survival analysis of VISTA after a median >3 years of follow-up and with the majority of patients having received subsequent therapy. We confirmed the previously demonstrated OS benefit of VMP versus MP, examined the use of subsequent therapy and its efficacy following VMP and MP, and evaluated the survival of patients who had received subsequent therapy. Patients were randomized to receive nine 6-week cycles of VMP (N=344; bortezomib 1.3 mg/m2, d 1, 4, 8, 11, 22, 25, 29, 32, cycles 1–4, d 1, 8, 22, 29, cycles 5–9; melphalan 9 mg/m2 d 1–4, prednisone 60 mg/m2, d 1–4, all cycles) or MP (N=338) alone. Response was assessed using EBMT criteria with central laboratory M-protein analysis. After disease progression, patients were followed for survival and subsequent therapy, including investigator-assessed best response to subsequent therapies. The median age of patients was 71 years, 30% were aged ≥75 years, 34% had ISS stage III MM, and 33% had β2-microglobulin >5.5 mg/L. After median follow-up of 36.7 months, there was a 35% reduced risk of death with VMP vs MP (hazard ratio [HR] 0.653, p=0.0008); median OS was not estimable vs 43.1 months, and 3-year OS rates were 68.5% vs 54.0% with VMP vs MP, respectively. This OS benefit was seen consistently across patient subgroups predefined by baseline characteristics. Within the VMP arm, OS was longer among patients aged <75 vs ≥75 years (HR 1.664, p=0.011; 3-year OS: 74.1% vs 55.5%); by contrast, there were no significant differences, although there were trends to longer OS among patients with creatinine clearance ≥60 versus <60 mL/min (HR 1.291, p=0.238; 3-year OS: 74.5% vs 63.1%) and patients with standard- vs high-risk cytogenetics (HR 1.346, p=0.399; 3-year OS 71.6% vs 56.1%). At data cut-off (16 March 2009), 178 (52%) VMP and 233 (69%) MP patients had received subsequent therapy; median time to subsequent therapy (28.1 vs 19.2 months, HR 0.527, p<0.0001) and median treatment-free interval (17.6 vs 8.4 months, HR 0.543, p<0.0001) were superior with VMP vs MP. Receipt of and response to subsequent bortezomib-, thalidomide-, and lenalidomide-based therapy are summarized in the Table. Median survival from start of subsequent therapy following VMP and MP was 30.2 vs 21.9 months (HR 0.815, p=0.21) among all patients receiving subsequent therapy. This updated analysis of VISTA confirms that VMP results in significantly longer OS compared with MP, despite 50% of MP patients being rescued with bortezomib-based therapy in the relapsed setting. VMP treatment used upfront appears more beneficial than treating with conventional agents and saving bortezomib- and other novel-agent-based treatment until relapse. Subsequent therapies appeared similarly effective in the VMP and MP arms, with our analysis also demonstrating the benefit of retreatment with bortezomib-based therapies following VMP. In addition, post-relapse survival among all patients receiving subsequent therapy appeared longer following VMP, indicating that frontline bortezomib use does not induce more resistant relapses.

Abstract Abstract 3094 Background: Allogeneic hematopoietic stem cell transplantation (allo-HCT) is a potentially curative treatment for patients with multiple myeloma (MM) but its use is limited by high non-relapse mortality (NRM). European Group for Bone Marrow transplant (EBMT) risk score is a validated predictor of outcome for patients undergoing allo-HCT for hematological malignancies. It takes into consideration patient's age, donor's gender and type, disease status and the interval from diagnosis to allo-HCT, with the score ranging from 0 to 7. We assessed the impact of EBMT risk score in MM patients undergoing allo-HCT. Methods: A total of 189 patients with MM who underwent HSCT between November 1985 and June 2010 at MD Anderson Cancer Center were included in the analysis. Results: Patient characteristics are summarized in Table 1. There were 110 males (58%) and 79 females (42%) with a mean age of 50 years (range 28–70). Donors were related in 146 patients (HLA-identical=131, 1 antigen mismatched (AGMM) = 5, 2 AGMM =1, 3AGMM=1, syngeneic=8) and unrelated in 43 patients (HLA identical= 37, 1AGMM=4, 2AGMM=1, unknown=1). One-hundred and twelve patients had prior autologous transplants (auto-HCT). Of these 83 had 1, 28 had 2 and 1 had 3 prior auto-HCT, respectively. Median time from diagnosis to allo-HCT was 24.7 months (range 3.3–232) and median overall follow up was 13 months (0.2–266). Overall 94 patients (49%) had progressed before last follow-up. Incidence of all-cause mortality was 138 (73.4%) with 69 (36%) of all deaths attributed to NRM. KM estimates of 2-year PFS and OS were 25% and 42%, and 5-year PFS and OS were 16% and 27%, respectively. Cumulative incidence (CI) of grade 2–4 and grade 3–4 acute graft versus host disease (aGVHD) was 33% and 13%, respectively. Cumulative incidence of overall and extensive chronic GVHD (cGVHD) was 47% and 17%, respectively. EBMT risk score was, 0–3 for 41 (21.7%), 4 for 72 (38.1%) 4 and 5–7 for 76 (40.2%) patients. EBMT risk score was higher for males, African-Americans and older allo-HCT recipients, patients with higher LDH levels (>618mg/dl), ß2-microglobulin >3.5mg/dl and patients with bone marrow plasmacytosis. Median PFS in patients with EBMT scores 0–3, 4 and 5–7 were 10.1, 8.4 and 6.4 months, respectively (P=0.0036). Median OS in patients with EBMT scores 0–3, 4 and 5–7 were 39, 15.8 and 9.6 months, respectively (p=0.001). Cumulative NRM in patients with EBMT scores 0–3, 4 and 5–7 were 37% (15/41), 36.1% (26/72) and 37.3% (28/75), respectively (p= 0.234). Cumulative incidence of progression in patients with EBMT scores 0–3, 4 and 5–7 were 36.5% (15/41), 50% (36/72) and 56.5% (43/76), p=0.119. Compared to those with EBMT risk score (0–3), individuals with EBMT risk scores >5 had a higher risk of all-cause mortality (HR 2.34, 95% CI 1.44–3.80), and disease progression (HR 3.06, 95% CI 1.67–5.61). Addition of ß2-microglobulin, BM plasma cells or prior response status alone or in combination with EBMT risk score significantly improved the discrimination properties of the model containing EBMT score alone (p<0.05). Conclusions: EBMT risk score is an independent predictor of survival in MM patients undergoing allo-HCT. Addition of myeloma-specific factors predictors (ß2-microglobulin, plasma cell infiltration and prior response status) to EBMT score significantly improves its prognostic impact.

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.

Abstract Introduction Multiple myeloma (MM) causes lytic bone lesions, osteopenia, and fractures, which increase the morbidity of MM patients. Results from small previous studies have indicated that fractures in MM have a negative effect on survival. Aims The aim of the study was to evaluate the impact of fractures on survival in MM patients diagnosed in Sweden in the years 1990-2013. Furthermore, to analyze the effect of bone fractures at MM diagnosis on subsequent survival. Methods Patients diagnosed with MM in 1990-2013 were identified from the Swedish Cancer Registry. Information on date of birth, diagnosis, and death were collected from the Registry of Total Population. Information on all fractures were retrieved from the Swedish Patient Registry. Cox regression model was used with fractures as time-dependent variables. The effect of fractures on survival was assessed for any fracture or a subtype of fracture (a specific bone fracture or ICD-coded pathologic fracture). Either first fracture or the first subtype of fracture was used in the analysis. The effect of a fracture at MM diagnosis (within 30 days before or 30 days after MM diagnosis) on survival was also estimated using a Cox regression model. All models were adjusted for age, sex, time of diagnosis, and previous fractures. Results A total of 14,008 patients were diagnosed with MM in the study period. A total of 4,141 (29.6%) patients developed a fracture including fractures that occurred within a year before MM diagnosis and thereafter. Hereof 2,893 (20.7%) patients developed a fracture after MM diagnosis. The risk of death was significantly increased for patients that developed a fracture after the time of MM diagnosis with a hazard ratio (HR) of 2.00 (95% confidence interval (CI) 1.91-2.10) for all fractures combined. The risk of death was significantly increased for patients that developed all subtypes of fractures after MM diagnosis except ankle fractures. The risk of death was significantly increased for patients that developed pathologic fractures (HR=2.17; 95% CI 2.03-2.32), vertebral fractures (HR=1.73; 95% CI 1.61-1.87), hip fractures (HR=1.99; 95% CI 1.82-2.18), femoral fractures (HR=2.62; 95% CI 2.32-2.98), humerus fractures (HR=2.57; 95% CI 2.32-2.86), forearm fractures (HR=1.24; 95% CI 1.05-1.46), and rib fractures (HR=1.52; 95% CI 1.31-1.77), but not for ankle fractures (HR 1.07; 95% CI 0.79-1.44). A total of 942 (6.7%) of all MM patients were diagnosed with a fracture within 30 days before or 30 days after MM diagnosis. The patients with a fracture at diagnosis were at a significantly increased risk of death compared to those without (HR 1.31; 95% CI 1.21-1.41; Figure) Conclusions Our large population-based study, including over 14,000 patients diagnosed with MM in Sweden in the years 1990-2013, showed that MM patients that developed a fracture after the time of diagnosis were at twofold increased risk of dying compared to MM patients without a fracture. Furthermore, MM patients with a fracture at diagnosis had a 30% higher risk of dying compared to patients without a fracture. Our results indicate that fractures in MM reflect a more advanced disease at diagnosis and stress the importance of managing MM bone disease in all MM patients. Figure. Figure.

Abstract Aims: Autologous stem cell transplantation (ASCT) is an important component in the treatment of newly diagnosed multiple myeloma (MM). However, relapse following ASCT is considered almost inevitable, with a median time to progression (TTP) of approximately 23-26 months (without maintenance) and 40-46 months (with maintenance)(Attal MA et al. N Engl J Med 2012; 366:1782-1791; McCarthy PM et al. N Engl J Med 2012; 366:1770-1781). However, some patients can experience a prolonged period of remission with ASCT. The purpose of this study was to identify and characterize patients who have an exceptional response to upfront ASCT without maintenance therapy, and to determine the frequency of relapse in such patients. Methods: We searched the Mayo Clinic Multiple Myeloma bone marrow transplant database for patients who were diagnosed with MM between Aug 1, 1988 to Jan 3, 2006, and underwent ASCT within 12 months of initial diagnosis. For the purposes of this study, we defined exceptional responders as patients who were free of progression for 96 months or more, which is 2-3 fold more than the median TTP expected in this population. Since maintenance therapy was not standard of care at the time, only a small minority (6) of patients with prolonged TTP had received maintenance therapy; these patients were excluded since the study was focused on exceptional response with ASCT alone. One patient who had a tandem autologous transplant was excluded. Results: 509 patients underwent transplant during the study period. Of those, 46 (9%) met criteria for exceptional response. Twenty seven (59%) were female, 19 (41%) were male. Median age was 57.28 years, range, 31.9-73.0. Of 45 patients with response data available, the best response status was complete response or better in 32 patients (73.3%), VGPR in 4 patients (8.9%), and PR in 8 patients (17.7%). FISH data were available during the disease course for 41 patients. Of these, the majority, 28 patients (68.3%), had no abnormalities detected by the probes used; 3 patients (7.3%) had high risk cytogenetics (t(4;14) in 2 patients and t(14;16) in one patient) , 4 (9.8%) had trisomies; 6 patients had other isolated abnormalities. At last follow up, 23 patients have progressed (50%); 14 (30.4%) have died, including one who died without progression to MM. The median overall survival from time of diagnosis of the exceptional responders was 18.5 years, range 9.2-22 years. From the landmark time of 96 months, the median TTP was 6.2 years, range, 0.4-10.6 years (Figure 1); No plateau was seen in the TTP curve. From the landmark time of 96 months, the median OS was 10.5 years, range, 0.4-14 years. Conclusions: We conclude that approximately 10% of patients with newly diagnosed myeloma have an exceptional response to a single ASCT without maintenance therapy. These patients have a remarkable overall survival, both from diagnosis and from the landmark time point where they are classified as having achieved an exceptional response. Although TTP from the landmark time point is excellent, with median TTP of 6.2 years, there appears to be no plateau in the curve indicating ongoing risk of relapse despite a prolonged period of disease stability. Exceptional responders tended to have normal FISH studies (likely an indicator of responsive, low-tumor burden disease), and nearly 20% achieved this state despite not attaining a complete response.

Risk Of Death

Background: Cytogenetic abnormalities detected by fluorescence in situ hybridization (FISH) are known to differentially impact prognosis in patients with chronic lymphocytic leukemia (CLL). Deletion6q23 (del6q23) has been reported in ~2-3% of CLL patients at diagnosis; however, its prognostic significance remains indeterminate. Methods: We identified previously untreated CLL patients from the Mayo Clinic CLL Database seen between 1/1995 - 2/2020 who had FISH performed. The clinical characteristics, concomitant cytogenetic abnormalities, time to first therapy (TTFT), and overall survival (OS) were compared between patients with del6q23 to those without this abnormality. TTFT was analyzed from FISH date until treatment or last known untreated date, accounting for competing risk of death. OS was analyzed using Kaplan-Meier methods from FISH date. In a matched (CLL-IPI risk score and sex) analysis, Cox regression analysis was used to determine the association between TTFT/OS and presence of del6q23. The Mayo Clinic IRB approved this study. Results: A total of 3101 CLL patients were identified; their median age at diagnosis was 64 years and 66% were male. Of these patients, 42 (1.3%) had evidence of del6q23 by FISH. Compared to patients without del6q23, patients with del6q23 carried a more adverse clinical and cytogenetic profile at the time of diagnosis including advanced Rai stage (22% Rai III/IV vs. 9% Rai III/IV; P = 0.002), unmutated IGHV genes (91% vs. 43%; P &lt; 0.001), and high/very high risk CLL-IPI (50% vs. 27%; P &lt; 0.001). Del6q23 was the sole abnormality in 13 patients (31%). Of the remaining patients, del6q23 was concomitantly present with del13q in 8 patients (19%), and with either del11q or del17p in 21 patients (50%). Of the 42 patients with del6q23, 29 received first line therapy: chemoimmunotherapy in 16 patients, BTK inhibitor in 7 patients, and an anti-CD20 monoclonal antibody alone in 6 patients. The median follow-up of the entire cohort was 7.3 years. The median TTFT in patients with del6q23 was 0.7 years while the 5-year OS was 76%. Patients with del6q23 demonstrated significantly shorter TTFT and reduced OS when compared to patients without del6q23 (Figures 1A and 1B). The shorter TTFT was also evident for patients with del6q23 compared to patients without del6q23 divided according to the Dohner risk category (Figure 2A), although there was no difference in OS between these groups of patients (Figure 2B). Because del6q23 patients were enriched for other unfavorable prognostic markers, we identified four control patients without del6q23, matched by CLL-IPI risk score and sex, to each treatment-naïve patient with del6q23. Patients with del6q23 showed a borderline statistically significant shorter TTFT (median 0.7 years versus 3.9 years; P = 0.07) and a nonsignificant association with OS (median 10.9 years versus 10.3 years; P = 0.28). Conclusion: Del6q23 by FISH in previously untreated CLL represents an uncommon abnormality. When compared to patients without del6q23, patients with del6q23 tend to have more adverse clinical and cytogenetic profiles at baseline, which likely confer a worse prognosis as reflected by shorter TTFT compared to patients without this abnormality.
