Disparities in Healthcare Resource Utilization for Multiple Myeloma

Abstract Background: Nearly half of older African-Americans who develop multiple myeloma (MM) do not receive systemic treatment. Those who do are less likely to receive newer treatments, such as novel agents and stem cell transplant, than their peers. In this study, we sought to determine if disparities in resource utilization exist even among patients receiving similar treatment. Methods: All newly diagnosed MM cases from 2007-2013 in the SEER-Medicare dataset were reviewed along with their corresponding claims data through 2014. We excluded cases 1) not enrolled in Medicare Part A, B, and D; 2) HMO enrollees; 3) those diagnosed prior to age 65; 4) all patients who did not receive a proteasome inhibitor and/or an immunomodulatory drug within 6 months; 5) those who underwent stem cell mobilization or transplantation; or 6) died within 12 months of MM diagnosis. All reported medical costs including both those paid by Medicare and patient copays for the first 12 months post-diagnosis were captured and adjusted for inflation. Results: 2,841 patients were included. The median age was 74 at diagnosis (range 65-96) and 51% were male. 79% (n = 2,247) were white, 14% (n = 403) African-American/Black, and 7% (n = 191) were another race. Overall, the median expenditure was $127,054 in the 12 months post-diagnosis; $121,400 for African-Americans, $127,810 for whites, and $119,209 for other races. After controlling for age, gender, comorbidities, a proxy measure of performance status, and MM related renal impairment and bone disease, African-American patients had $10,524 less in overall expenditures on average than white patients. This can partly be attributed to lower expenditures on MM drugs. On average African-American patients had $5,520 less in MM drug expenditures (p = 0.0062). African-Americans also had 9.3 less days of interaction with outpatient services compared to their white peers (p < 0.0001), but 4.6 more days in inpatient settings (p = 0.0208). There was no statistically significant difference between white patients and patients of races other than white or African-American in overall expenditure or MM drug expenditure but members of other races had 8.2 less days of interaction with outpatient services (p = 0.0004) and 5.7 less days in inpatient settings (p = 0.0350). The estimated median overall survival for African-American patients was 44 months (95% CI 40-51) compared to 47 (45-50) for white patients and 57 (44-66) for patients of other races (p = 0.097). Race was not associated with overall survival in multivariate analysis. Conclusion: Minority patients with MM received fewer services during the 12 months post-diagnosis. It is currently unclear if this is due to inferior care, overuse among white patients, or related to the clinical needs of the patients.

Abstract Introduction African-American ethnicity, male sex, older age and obesity are accepted risk factors for multiple myeloma (MM). Obesity early in life is a risk factor for many cancers, including MM; most studies have focused on populations of European origin. African-Americans have a higher prevalence of obesity than other populations, and may have a distinct genetic contribution to this condition. We established a multi-center collaborative study to investigate possible explanations for the excess risk of MM among African-Americans. The aim of the present case-case analysis was to determine whether body mass index (BMI) was associated with risk factors and clinical characteristics at presentation in African-American MM patients. Methods Patients diagnosed with active MM since January 1, 2009 were recruited from nine outpatient centers and three Surveillance, Epidemiology, End-Results Program (SEER) population-based cancer registries. Information on weight and height at 20 years of age and at 5 years prior to diagnosis was obtained from questionnaires. Clinical information collected included age at diagnosis, stage, percent plasmacytosis on bone marrow biopsy, β2 microglobulin level, Ig serotype, light vs. heavy chain disease, and presence of lytic bone lesions. BMI (ht/wt2) was categorized into 3 levels (normal <25, overweight 25-29, obese >30) according to World Health Organization standard. The Pearson chi-square test was used to test the association between BMI category, and risk factors and clinical characteristics. Mean ages at diagnosis across BMI categories were compared using linear regression and a t-test for trend calculated. Results To date, 1,044 African-American MM patients have been enrolled and of those, 1,014 provided a DNA sample. At present, 970 patients have completed a questionnaire, clinical records have been abstracted for 823 patients, and 509 patients have some information on gender, age at diagnosis, weight, height and clinical characteristics.The mean age at diagnosis was 59. Increasing BMI at age 20 was associated with younger age at diagnosis (p= 0.0004), whereas BMI at 5 years prior to diagnosis was not associated with age at diagnosis (p=0.9477). Among men, mean age at diagnosis decreased with increasing BMI at age 20 (p= 0.0125) (Table 1a) and at 5 years prior to diagnosis (p=0.0252) (Table 1b). Among women, the trend was signficant at age 20 (p=0.0018) (Table 1a) but not at 5 years prior to diagnosis (p= 0.7094) (Table 1b). Increasing BMI was not significantly associated with any other clinical characteristics. Conclusion/Discussion In a large collection of African-American MM patients, we observed a strong association between increasing BMI at age 20 and younger age at diagnosis. A similar trend was observed in men only at 5 years prior to diagnosis, consistent with previous reports. Obesity is one of the few known potentially modifiable risk factors for MM. Younger age at diagnosis reflects an earlier accumulation of either or both genetic and environmental risk factors. Obesity at an early age may influence MM risk through shared biological pathways such as interleukin-6 and insulin-like growth factor, by contributing to chronic B-cell activation, thereby increasing susceptibilty for MM later in life. The significance of the gender difference for the association closer to diagnosis is unclear and requires additional study. Disclosures: Terebelo: Amgen: Honoraria; Millennium: Honoraria.

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

Abstract Introduction: Panobinostat is a potent pan-deacetylase inhibitor (pan-DACi) that targets key aberrations in multiple myeloma (MM) cell biology, including epigenetics and protein metabolism. In the phase 3 clinical trial PANORAMA 1, panobinostat in combination with bortezomib and dexamethasone (PAN-BTZ-Dex) led to a statistically significant and clinically relevant increase in progression-free survival of approximately 4 months compared with that with placebo plus bortezomib and dexamethasone (Pbo-BTZ-Dex). Further analyses of patient outcomes by prior treatment demonstrated that the magnitude of PFS benefit was greatest among patients who received at least 2 prior regimens, including bortezomib and an immunomodulatory drug (IMiD; PAN-BTZ-Dex [n = 73]: 12.5 months [95% CI, 7.3-14.0 months]; Pbo-BTZ-Dex [n = 74]: 4.7 months (95% CI, 3.7-6.1 mo; HR 0.47 [95% CI, 0.32-0.72]). These data supported the regulatory approvals of PAN-BTZ-Dex for the treatment of patients with multiple myeloma who received at least 2 prior regimens, including bortezomib and an IMiD. Here we present the final analysis of overall survival (OS) for the entire patient population and among patients who received at least 2 prior regimens, including bortezomib and an IMiD. Methods: The study design for the PANORAMA 1 trial was described previously (San-Miguel. Lancet Oncol. 2014;15:1195-206). The key secondary endpoint was OS. As of June 29, 2015, the 415 events required to conduct the final analysis of OS had been observed. Kaplan-Meier estimation was utilized for OS analyses for the entire population (N = 768), the pre-specified subgroup of patients who received prior bortezomib and IMiD (n = 193), and patients who received at least 2 prior regimens including bortezomib and an IMiD (n = 147). Results: The median OS of patients who received PAN-BTZ-Dex in the overall population was 40.3 months (95% CI, 35.0-44.8 months) vs 35.8 months (95% CI, 29.0-40.6 months) for the Pbo-BTZ-Dex arm with HR 0.94 [95% CI, 0.78-1.14], P = .5435 (Fig 1A). The percentage of patients in each arm who received post-study therapy was 37.7% in the PAN-BTZ-Dex arm and 48.8% in the Pbo-BTZ-Dex arm. The median OS of patients who received at least 2 prior lines, including bortezomib and an IMiD, was 25.5 months (95% CI, 19.6-34.3 months) in the PAN-BTZ-Dex arm vs 19.5 months (95% CI, 14.1-32.5 months) in the Pbo-BTZ-Dex arm (Fig. 1B). The proportion of patients in this subgroup who received post-study therapy was 35.6% in the PAN-BTZ-Dex arm and 66.2% in the Pbo-BTZ-Dex arm. Conclusion: For the overall PANORAMA 1 study population, patients in the PAN-BTZ-Dex arm demonstrated an increase in median OS of 4.5 months vs patients in the Pbo-BTZ-Dex arm, but this result was not statistically significant (P = .5435). Median OS was also slightly longer for the PAN-BTZ-Dex arm among the more heavily pretreated subgroup of patients who received at least 2 prior regimens, including bortezomib and an IMiD. A higher percentage of patients on the Pbo-BTZ-Dex arm received post-study therapy vs the PAN-BTZ-Dex arm, which may have confounded the OS results. In summary, PAN-BTZ-Dex demonstrates statistically significant increases in PFS vs Pbo-BTZ-Dex in patients with relapsed or relapsed and refractory MM; however, this did not translate to a statistically significant increase in OS. Future trials will plan to focus on further optimization of dose and schedule of panobinostat and bortezomib to improve outcome, as well as novel combinations with other agents, including IMiDs and next-generation proteasome inhibitors.

Monoclonal Gammopathies

Abstract Introduction: Multiple myeloma patients over the age of 65 represent the majority of myeloma population. The main goal was to evaluate treatment outcomes in terms of overall survival for elderly patients based on initial choice of anti-myeloma drugs, and to find potential factors affecting survival. Patients and Methods: This is a retrospective registry based analysis from the Registry of monoclonal gammopathies of the Czech Myeloma Group. Patients with multiple myeloma diagnosed between 2007-2016 over the age of 65 with symptomatic myeloma were included in the analysis. Basic demographic data and disease characteristics were obtained. The Kaplan-Meier estimates were completed by the Greenwood confidence interval. The log-rank test was used to estimate the statistical significance of the difference between the curves. The Cox proportional hazards model was performed to explore the univariate significance of risk factors. Results: Data from 1410 MM patients were obtained. Gender [HR 1.316 (1.124-1.541), p=0.001], age [above 75 vs. 66-75, HR 1.437 (1.221-1.692), p< 0.001], creatinine levels [at cutoff 152 µmol/L, HR 1.613 (1.365-1.905), p< 0.001] and ECOG performance status [0-1 vs. 2-4, 1.869 (1.594-2.191), p< 0.001] were found to significantly affect overall survival. Moreover these risk factors have cumulative effect on overall survival of the patients. Overall survival of patients regardless to above mentioned risk factors treated with upfront bortezomib (N = 880) was median OS 40.4 months (CI: 36.1-44.7), patients treated with upfront thalidomide (N = 370) had median OS 48.1 months (CI: 41.0-55.2), for lenalidomide (N = 64) median overall survival was 53.2 months (CI: 44.6-61.8) and for combination of bortezomib and thalidomide (N = 46) 32.2 months (CI: 26.6-37.8). When any of these risk factors was present the OS in each group shortened. In the group of patients with no risk factors (N = 255) the median OS for bortezomib (N = 126) was not reached, for thalidomide (N = 96) the median OS was 66.3 months (CI: 43.1-89.6), for lenalidomide (N = 17) 71.1 months (CI: 44.8-97.4) and for combination of bortezomib and thalidomide (N=8) was not reached. In the group of patients with 1 risk factor (N = 514) the median OS for bortezomib (N = 303) was 46.1 months (CI: 36.2-56.1), for thalidomide (N = 141) 56.2 months (CI: 47.5-64.9), for lenalidomide (N = 29) 49.0 months (CI: 9.7-88.2) and for combination of bortezomib and thalidomide (N=20) was not reached. In the group of patients with 2 risk factors (N = 420) the median OS for bortezomib (N = 288) was 34.0 months (CI: 24.7-43.4), for thalidomide (N = 87) 31.9 months (CI: 22.8-40.9), for lenalidomide (N = 14) 33.2 months (CI: 0.0-67.6) and for combination of bortezomib and thalidomide (N=20) 29.4 months (CI: 7.6-51.1). In the group of patients with 3-4 risk factors (N = 221) the median OS for bortezomib (N = 163) was 19.2 months (CI: 14.9-23.5), for thalidomide (N = 46) 18.9 months (CI: 13.0-24.7), for lenalidomide (N = 4) 6.1 months (CI: 0.0-63.0) and for combination of bortezomib and thalidomide (N=3) 14.3 months (CI:-). Conclusion: The overall survival of patients above the age of 65 shows promising results with the use of novel agents. The treatment outcomes seem to be generally affected by overall condition, age and gender of the patient rather than treatment modality used upfront. Figure. Figure.

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 Background: The introduction of novel therapeutics has led to improved outcomes in patients with multiple myeloma (MM). MM and its precursor lesion smoldering multiple myeloma (SMM) have traditionally been associated with increased mortality despite treatment. We aimed to assess the impact of a diagnosis of SMM and MM compared to the general population in the context of established prognostic factors. Methods: We studied the overall survival of 1697 patients with smoldering multiple myeloma (SMM, n = 582) and multiple myeloma (MM, n = 1115) diagnosed at Mayo Clinic between 01/2005 and 12/2015. Expected survival accounting for age and sex was calculated using the United States general population (US) as the reference group. Observed and expected overall survival was expressed as the standardized mortality ratio (SMR) of observed to expected deaths. Kaplan-Meier overall survival estimates were calculated and the log-rank test was used to compare overall survival in subgroups. The subgroups of interest were based on the International Staging System (ISS) and the presence of fluorescence in situ hybridization (FISH) high-risk cytogenetics: t(4;14), t(14;16), t(14;20), and del(17p). Proportional hazards regression models were used to assess the associations between the aforementioned prognostic factors and overall survival. P-values below 0.05 were considered statistically significant. Results: The median age at diagnosis in patients with SMM and MM was 65 (32 - 92) and 63 years (24 - 90), respectively. Two hundred forty-nine patients (57%) and 663 (60%) were male. The median follow-up in patients with SMM and MM was 4.7 (0.1 - 11.0) and 2.6 years (0.2 - 9.5). The median overall survival for patients with SMM and MM was 9.0 (95% CI 8.4 - 9.7) and 7.9 years (6.4 - 8.7). With age- and sex-matched population controls as the reference, the SMRs in patients with SMM and MM were 2.6 (95% CI 2.2 - 3.0) and 4.6 (4.1 - 5.2). Among those MM patients with available data on ISS staging and FISH cytogenetics, 30% (236/780) had ISS III and 21% (188/878) had high-risk cytogenetics. Patients with MM (compared to SMM) experienced worse overall survival (HR 1.5, 95% CI 1.2 - 1.8, p < 0.001, n = 1697). Patients with ISS I/II MM (compared to SMM) experienced similar survival (HR 1.0, 95% CI 0.8 - 1.3, p = 0.698, n = 1131). Patients with ISS III MM (compared to MM with high-risk cytogenetics) experienced similar survival (HR 1.3, 95% CI 0.9 - 2.0, p = 0.128, n = 329). Conclusions: Patients with SMM and MM in this cohort experienced excess mortality compared to the general population. In the absence of universal screening the true morbidity and mortality of patients with SMM and MM remains unknown and is likely overestimated in hospital-based cohorts. Overall survival in patients diagnosed with SMM and patients with ISS I/II MM receiving contemporary anti-myeloma therapy was clinically indistinguishable. Patients treated for ISS III MM experienced overall survival similar to patients with cytogenetic high-risk disease. MM remains associated with excess mortality, the magnitude of which varies considerably based on the presence of additional tumor and host factors. The outcomes with modern therapy among the ISS I/II patients highlight the potential for improving outcomes of SMM by early intervention, especially for the higher risk patients. Figure. Figure.

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.

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.

Abstract Introduction. Efficacy and safety of daratumumab monotherapy (DARA mono) in relapsed/refractory multiple myeloma (rrMM) has been shown in the single-arm phase I/II trial GEN501 and the single-arm phase II trial SIRIUS (1, 2). Since then, several indirect treatment comparisons of DARA mono versus comparator therapies have been published showing consistent results with an overall survival benefit for DARA mono (3, 4, 5, 6). This analysis compares efficacy and for the first time also safety of DARA mono data versus an international historic control group, adjusting for differences in patient populations based on individual patient level data (IPD). Methods. IPD from the SIRIUS trial and from the International Myeloma Foundation (IMF)-cohort (7), a retrospective, multicenter cohort, were compared using a multivariate Cox proportional hazards model, on the endpoints of efficacy (overall survival (OS)) and safety (discontinuation due to adverse events (DISCONAE)). The IMF-cohort included patients with rrMM who received at least three prior lines of therapy, were refractory to both an immunomodulator (IMiD) and a proteasome inhibitor (PI), and were exposed to an alkylating agent. An inclusion criterion for the historic control group in this analysis was treatment with EU approved regimens. Baseline covariates adjusted for in the regression model included age, gender, prior lines of therapy, albumin, beta-2 microglobulin, prior exposure to pomalidomide and carfilzomib, and PI/IMiD refractory status. Several sensitivity analyses were run, including multiple imputation of missing values. Results. Data from 106 patients treated with DARA mono (16 mg/kg) were available from SIRIUS; 258 patients from the IMF chart review fulfilled the inclusion criteria; most frequent treatment regimens contained pomalidomide plus dexamethasone (PomDex) (n=172), bortezomib (n=31), carfilzomib (n=21), cyclophosphamide (n=14) and lenalidomide (n=9). The adjusted HR for OS was 0.41 [0.25, 0.69], p<0.001, and 0.23 [0.05, 1.00], p=0.050 for DISCONAE, in favor of daratumumab. Results were consistent across a range of sensitivity analyses and were similar when restricting the comparison to DARA vs. PomDex, with HR=0.35 [0.19, 0.64], p<0.001 for OS and 0.20 [0.03, 1.54], p=0.123 for DISCONAE. Conclusions. This comparison using real-world data of rrMM patients suggests improved efficacy and safety for DARA mono compared to approved therapy regimens used in clinical practice, including PomDex.

High Risk Disease

Abstract Background: MM treatment (Tx) advances have greatly improved clinical outcomes for patients (pts). A recent study demonstrated improved survival in MM through the past decade attributable to the impact of initial therapy with lenalidomide, bortezomib, and thalidomide. The greatest impact was observed in older pts (Kumar, et al. Leukemia, 2014). Connect MM, the first and largest prospective, observational, US-based, multicenter registry was designed to characterize pts, Tx patterns, and outcomes in newly diagnosed MM (NDMM). Methods: This ongoing registry was initiated in September 2009. Eligible pts with NDMM (diagnosis must have occurred within 2 mos of study entry) were enrolled at 234 US sites. Data were collected at baseline and each subsequent quarter using an electronic case report form. The initial enrollment includes all pts who had provided informed consent as of November 1, 2012 (N = 1493). The data cutoff for this analysis was Dec 10, 2013. A total of 1444 pts were treated and were included in overall survival (OS) analyses. Survival was examined for all treated pts adjusting for pt and Tx characteristics including age, autologous stem cell transplant (ASCT) status, gender, race, disease risk factors (International Myeloma Working Group [IMWG] high risk vs. non-high risk), and therapy received (triplet vs. non-triplet) among others. Triplet therapy was defined as any combination of 3 or more drugs during the first Tx regimen. OS was estimated using Kaplan-Meier methods and comparisons across groups were assessed used the log-rank test. Results: At the time of data cutoff, 1493 pts were enrolled with 1444 having received Tx. Of the treated pts 253 pts (18%) had IMWG high-risk disease and 108 pts (7%) had del(17p) at baseline. Median age was 67 y (range, 24-94 y), 57.2% were male, and 81.9% were white. Median follow-up was 29 mos (0-49.4 mos). The median OS for all treated pts was 44.4 mos. When assessed by age group, OS was significantly different (log-rank P < .0001) with a median of 47.6 mos for pts aged < 65 y (n = 632), 45.0 mos for those aged 65 to < 75 y (n = 443), and 33.7 mos for those aged ≥ 75 y (n = 369). OS was significantly longer for pts with ASCT vs. no ASCT (P < .0001), but not different by gender (P = .962) or race (Caucasian vs. African American vs. other; P = .250). Three-year OS probabilities by subgroup are listed in Table 1. When considering risk factors, IMWG risk was borderline significant (high vs. non-high; P = .106), and presence of del(17p) by cytogenetics and FISH was associated with significantly shortened OS (P = .005; Figure 1A). Interestingly, use of triplet therapy vs. non-triplet therapy was associated with significantly prolonged OS regardless of IMWG risk (non-high: P < .0001; high: P = .003; Figure 1B). However, no improvement was noted for triplet vs. non-triplet therapy in pts with del(17p). By multivariate analysis, the significant (P < .05) factors impacting OS were age (in 10-yr increments), International Staging System (ISS) disease stage, ECOG performance status, history of diabetes, anemia, renal function, and platelet count. Conclusions: This interim analysis based on initially treated pts demonstrated that age, ISS stage, and co-morbidities impact OS irrespective of IMWG cytogenetic risk. Triplet Tx was associated with significantly longer OS in pts regardless of IMWG risk status. This is the largest prospective pt cohort with high-risk disease including del(17p). Pts with high-risk disease did not have significantly lower OS vs. pts without high-risk features. Pts with del(17p) (p53 deletion) continue to have shorter OS approaching 3 y and increased survival with use of triplet therapy. Table 1.
