Abstract Introduction Hematopoietic stem cell transplant (HSCT) is commonly performed for the treatment of advanced hematological malignancies. Emerging data suggest non-relapse related events, including cardiac arrhythmias, increasingly limit anticancer outcomes and non-relapse mortality after initially successful HSCT. Yet, the relationship between HSCT and increased risk of arrhythmias after transplant remains controversial and unclear. Our aim was to evaluate the incidence and effect on mortality risk of arrhythmia development after HSCT. Materials and methods Leveraging the PubMed, Embase, Cochrane, Scopus and Clinicaltrials.gov databases, we identified all published studies evaluating the incidence and impacts of early arrhythmias after HSCT from January 1995 to July 2021 using PRISMA guidelines. We included all available observational studies (case-control, and cohort) and clinical trials without restriction of language or country of publication. The primary outcome was incidence of atrial fibrillation (AF) at 1 year of follow-up after HSCT. Secondary outcomes included the incidence of any arrhythmia across follow-up, the incidence of left atrium (LA) dilation, and non-relapse mortality associated with HSCT induced AF. Subgroup analysis based on type of HSCT treatment employed, allogenic (Allo-HSCT) or autologous (Auto-HSCT), was also performed. Variance weighted random effects modeling (DerSimonian and Laird) was used to define the associations between HSCT and AF and mortality events. Outcomes were reported as event rates, and relative risks (RR). Medians were reported with corresponding standard errors (SE). Heterogeneity was assessed using Cochrane Q-statistic which was quantified with I 2test (>75% was considered high heterogeneity). Publication bias was assessed using Eager's test where applicable. Further, the quality of included studies was assessed using the New-Castle Ottawa scale. Results Overall, from 769 articles, 12 cohort studies inclusive of 6,371 patients meeting study-criteria were identified. The mean incidence of AF was 8.8% (I 2:97%, P<0.001), including 5.2% (I 2:65%, P=0.05) within 1-year of any HSCT. The overall incidence of any type of arrhythmia was 11.2% (I 2 =95%, P≤0.001); Figure. Median time to AF onset was 10.3 days (SE= 1.2), but was longer in those treated with Allo-HSCT, at 71 days (SE=68.4); P<0.05. Among those treated with Allo-HSCT, 8.2% (I 2:73%, P<0.001) developed AF, including 6.5% (I 2:72%, P<0.01) at 1 year; the event rate for any type of arrhythmia was 8.3% (I 2:52%, P<0.001). In those treated with Auto-HSCT, the rate of AF was 8.7% (I 2=97%, P≤0.001) across follow-up. Among those with AF following HSCT therapy, LA dilatation was observed in 37.2% (I 2 =61.5%, P=0.1) among available studies. Similarly, mortality was higher among patients who developed AF vs. those without AF after HSCT (RR: 7.4, P=0.008, I 2 = 92.87). There was low risk of publication bias as assessed by visual inspection of funnel plot and Egger's regression test (P= 0.21); and low risk of bias within the included studies. Conclusion Atrial fibrillation is increasingly common after HSCT therapy, and associates with increased mortality. The presence of LA remodeling, reflected by atrial dilation, appears to portend AF risk. Further research into the mechanisms and predictors of AF after HSCT are needed. Figure 1 Figure 1.

Abstract Introduction The prognosis of patients with multiple myeloma (MM) has improved in the last years due to the important advances in the knowledge of the biology of the disease, the implementation of new drugs and the incorporation of autologous hematopoietic stem cell transplant (autoHSCT). The allogenic hematopoietic stem cell transplant (alloHSCT) continues to be controversial: it offers a curative potential but with the cost of high toxicity, limiting the procedure to those young patients with a high-risk disease. This procedure shall be performed in expert centers and, whenever possible, in the context of a clinical trial. In the following we describe the experience of our center with alloHSCT in advance multiple myeloma patients. Patients and methods A total of 18 patients were diagnosed with multiple myeloma received an alloHSCT during a 13 year period (1996-2013), with a median age of 46 ± 5.9 years. All of our patients received an allogenic HLA matched sibling donor with reduced-intensity conditioning. The majority of patients were transplanted because of advanced disease, relapse after an autologous transplant or as part of a sequential transplant in patient with a high risk disease. One patient received, in two occasions, an alloHSCT. Around 70% of patients had received more than 3 previous lines of treatment including, in nearly 95%, an autoHSCT. Patient's characteristics can be found on table 1, characteristics of the procedure can be found in table 2.Table 1.Patient«s CharacteristicsN (%)GenderMale Female10 (55,5%) 9 (44,4%)Secreted ProteinIgGκ IgG λ IgA κ BJ Plasmocitoma8 (44,4%) 4 (22,2%) 2 (11,1%) 3 (16,7%) 1 (5,6%)Debut DS stageII-A II-B III-A III-B Plasmocitoma5 (27,8%) 1 (5,6%) 8 (44,4%) 3 (16,7%) 1 (5,6%)Cytogentics at diagnosisMissing Unfavorable Favorable10 (55,5%) 6 (33,3%) 2 (11,1%)Previous lines of treatment²2 3-4 ³56 (33,3%) 10 (55,5%) 2 (11,1%)Previous autoHSCTYes No17 (94,5%) 1 (5,6%)Previous radiotherapyYes No8 (44,4%) 10 (55,6%)Disease status at transplantComplete remission Partial remission Relapse9 (50,0%) 3 (16,7%) 6 (33,3%)Table 2.Treatment characteristicsN (%)Conditioning regimenMyeloablative Reduced-intensity6 (33,3%) 12 (66.7%)Stem cell sourceBone marrow Peripheral blood4 (22.2%) 14 (77.8%)GVHD prophylaxisCsA+MTXCsA+CSCsA+MMF10 (55.6%) 3 (16.7%) 5 (27.8%)InfectionsYes No16 (88.9%) 2 (11.1%)MucositisYes No12 (66.7%) 6 (33.3%)Acute GVHDYes II-IV III-IV No4 (22.3%) 3 (16.7%) 1 (5.6%) 14 (77.8%)Chronic GVHDNo Limited Extensive8 (44.3%) 5 (27.8%) 5 (27.8%) Results: Transplant related mortality (TRM) before day 100th was one case due to a thromboembolic event. Global TRM was 16.6% (3 cases). The incidence of acute graft versus host disease (aGVHD) was 22%, controlled on most cases when corticosteroids were initiated. More than half of the patients developed chronic graft versus host disease (cGVHD), with an equal distribution on either presentation as limited or extensive. (Table 2) The total number of patients eligible for analysis was 17 (one patient was lost on follow-up). With a median follow up of 11 years, the overall survival (OS) was of 8.06 years [IC 95% 4,33-11,78] (figure 1.) and the estimated progression free survival (PFS) was of 25.83 months [IC 95% 8.87-42.79](figure 2). A total of 5 (29,4%) patients are still alive and 2 (11,7%) of them are in complete remission, of these 1 patient did not have a previous autoHSCT with a follow up of almost 15 years. Conclusions: Our results are similar to those reflected on the literature1-2. However we have to point out that our population is homogenous with advanced MM with more than 3 previous lines of treatment including in most cases auto-HSCT. In spite of this, morbility and mortality in our cohort was acceptable with the limitation of a high rate of cGVHD. There is a need of more studies including more patients to evaluate the role of alloHSCT in the era of new drugs for MM. References 1. Rosi-ol L et al.

Abstract Introduction: The standard of care for relapsed/refractory (R/R) classical Hodgkin lymphoma (cHL) is salvage therapy followed by autologous hematopoietic stem cell transplant (auto-HCT). Pre-apheresis absolute lymphocyte count (PA-ALC) is an independent prognostic factor for overall survival (OS) after transplant. We aimed to evaluate the effect of absolute lymphocyte count following auto-HCT and hypothesized that a higher post-transplant ALC at day +15 (PT-ALC) correlates with improved OS. Methods: A retrospective review was performed on patients with R/R cHL who underwent auto-HCT at Moffitt Cancer Center from 2000-2020. The following patient characteristics were collected: age at diagnosis, gender, initial stage and presence of B symptoms. Pretransplant variables including chemotherapy, number of cycles, response to therapy, and time from last chemo to apheresis were collected. Receiver-operator characteristics (ROC) curve was used to identify the ideal PT-ALC to predict overall survival. Patients were then identified as high ALC versus low ALC. Mann-Whitney, Pearson Chi-square, and Fisher exact test were used to compare baseline characteristics between the two groups. Univariate analysis of overall survival was done using Log-rank testing and Kaplan-Meier curve. Cox-regression analysis was used to evaluate the factors affecting OS. Results: A total of 259 patients were included in the study, with a median age of 35 years (range 14-76). ROC curve was used to identify the ideal PT-ALC affecting OS, and a cutoff value of 300/uL was determined (AUC 0.60; 95% CI: 0.52-0.68, Figure 1). In this cohort, 52 patients (16.6%) had low PT-ALC and 207 patients (65.9%) had high PT-ALC. There was no significant difference between the two groups in regards to patient age, gender, histology type, stage at presentation, number of salvage cycles, number of CD34 cells collected, or number of days required for apheresis. Patients with a high PT-ALC had higher pre-apheresis ALC (p<0.001). There was a trend toward significance with patients with high PT-ALC receiving non-chemotherapy salvage regimens (p=0.07, Table 1). However, PA-ALC was significantly higher in non-chemotherapy regimen (p=0.007). Patients with high PT-ALC had a longer OS after transplant than those with low PT-ALC, with median OS 11.8 years and 7.7 years, respectively (p=0.012, Figure 2). On multivariate analysis, the only factor associated with improved OS was high PT-ALC (p=0.015, Table 2). Conclusions: High PA-ALC and high PT-ALC are both independent prognostic factors for longer OS in patients with relapsed/refractory Hodgkin lymphoma after auto-HCT. High PA-ALC lead to higher PT-ALC. Although most of our patients received chemotherapy as salvage therapy prior to transplant, there was a trend toward higher PT-ALC in patients who received non-chemotherapy regimens. Future studies are required to determine the role of non-chemotherapy salvage regimens in improving lymphocyte counts during the peri-transplant period and, hence, improved survival.

Abstract Abstract 3109 Background: High dose melphalan (MEL) is a standard treatment for eligible patients with AL, a disease in which hematologic response is a key determinant of survival. With the advent of novel agents the role of stem cell transplant (SCT) for patients with AL is being questioned, especially given safety concerns. Yet with appropriate patient selection and the use of risk-adapted SCT (RA-SCT), treatment-related mortality (TRM) improved.(Br J Haem 2007;139:224; Bone Marrow Transplantation 2011; 46:970) Moreover, beginning in 2002, we showed in 2 consecutive phase II trials that following RA-SCT patients can safely receive consolidation with thalidomide and dexamethasone (TD) or bortezomib and D (BD), with the goal of improving hematologic response thereby extending overall survival (OS).(Br J Haem 2007;139:224; Amyloid 2010;17:80a) Consolidation was administered for patients achieving less than a complete response (CR). We now describe the outcomes of all patients with AL who underwent RA-SCT at Memorial Sloan-Kettering Cancer Center (MSKCC) since the year 2000. Methods: We performed a retrospective study to assess the OS of all patients who underwent SCT for a diagnosis of AL confirmed at MSKCC. Patients who had >2 major organs involved, NYHA class III or greater CHF, critical arrhythmias or cardiac syncope were ineligible for SCT. OS was calculated from transplant to date of death or last follow up. Median survival was estimated by Kaplan Meier methods. Log-rank test was used to determine whether survival functions differed by covariates of interest. Cumulative incidence function was used to estimate the incidence of cause-specific mortality. Results: A total of 151 patients underwent RA-SCT between February 2000 and June 2011; three lost to follow-up are excluded from this analysis. Of the remaining 148 patients 21%, 52% and 34% received RA-SCT at 100, 140 and 200mg/m2 of melphalan respectively based on age, renal function and cardiac involvement.(Blood 2002; 99: 4276) Five patients died within 100 days of SCT (TRM 3.4%). At a median follow up of 6.7 years, the median OS for all patients is 11.1 years (95% CI, 7.32 - not reached-NR) (Figure 1), and for patients who received MEL 100, 140 or 200 is 4.4 (95% CI, 2.7 – 6.3), NR and 11 years (95% CI, 8.2 – NR) respectively (P = <0.01). Cumulative incidence of disease related mortality at 2 years is 5.5%, and subsequently the rate of death from other causes exceeds that due to AL (Figure 2). Conclusions: RA-SCT for appropriately selected patients is safe and is associated with excellent long-term survival. Consolidation with novel agents may improve survival following RA-SCT and likely accounts for the similar OS seen in patients who received MEL 140 and 200. In the era of novel agents available for post-SCT consolidation, RA-SCT is an effective and important initial treatment for patients with AL.

Abstract Anti-PD-1 monoclonal antibodies have shown promising results in several hematologic malignancies. As a result, these agents are being tested in a growing number of clinical trials across multiple diseases and settings. Many participants in these trials will at some point become candidates for allogeneic hematopoietic stem cell transplant (HSCT); however, the safety and efficacy of HSCT may differ in patients previously exposed to PD-1 inhibitors given their immunomodulatory mechanism and long tissue half-life. Specifically, residual PD-1 inhibition post-HSCT could enhance allogeneic T-cell responses, which could augment the graft-vs-tumor (GVT) effect but also increase the incidence, severity or manifestations of graft-vs-host disease (GVHD) and other immune complications of HSCT. To report our experience in this setting, we retrospectively analyzed the outcomes of patients who had received a PD-1 inhibitor prior to HSCT. Between 2013 and 2015, 19 patients who previously participated in clinical trials with either pembrolizumab or nivolumab (administered in combination with ipilimumab in 1 patient) were transplanted at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Median age at HSCT was 32 (range 22-67). Histologies included HL (n=11), DLBCL (n=2), FL (n=2), PMBCL (n=2), EATL (n=1), and MCL (n=1). Patients had received a median of 4 (2-8) lines of therapy prior to PD-1 blockade. 79% of patients had received a previous autologous stem cell transplant (21% as part of planned tandem procedure). Patients received a median of 8 (3-20) cycles of a PD-1 inhibitor; 74% had intervening salvage therapy between PD-1 blockade and HSCT, and transplant occurred a median of 130 (range 7-260) days after the last dose of PD-1 inhibitor. At HSCT, 63% of the patients were in CR and 16% had refractory disease. All patients received reduced intensity conditioning (RIC). 5 (26%) received marrow grafts from haploidentical sibling donors; the remaining 14 received peripheral blood stem cells, 5 from a matched sibling, 7 from a matched, 1 from a unidirectional host-versus-graft and 1 from a bidirectional mismatched unrelated donor. 3 cases of veno-occlusive disease (VOD) (16% of patients) were observed, one of them fatal. The 180-day cumulative incidences of grade 2-4 and grade 3-4 acute GVHD were 32% and 11%, respectively, and the 1-year cumulative incidence of chronic GVHD was 30%. There were 4 treatment-related deaths, (1 from VOD, 3 from severe acute GVHD occurring within 14 days of HSCT). In addition, 6 patients developed a febrile syndrome with elevated transaminases (n=3), rash (n= 4), and arthralgias (n=1) shortly after transplant, which required prolonged courses of steroids. Only 3 patients relapsed. After a median follow-up of 10 (3-23) months for survivors, the 1-year overall (OS) and progression-free survivals (PFS) were 78% (95CI, 52-91) and 67% (95CI, 41-84), respectively (Figure). The 1-year cumulative incidences of relapse and non-relapse mortality (NRM) were 11% (95CI, 2-30) and 22% (95CI, 6-43), respectively. In conclusion, HSCT is feasible in patients previously treated with PD-1 inhibitors, with acceptable PFS and OS. Despite the heterogeneous patient population, small sample size, and limited follow-up to date, our results raise the possibility of important differences in the post-HSCT course of those patients. First, the relapse rate compares favorably to that expected for this cohort (1-year expected relapse rate based on Disease Risk Index mix 28%). Although this finding is at best suggestive given the sample size and follow-up time, it could reflect accentuation of GVT by prior PD-1 blockade. We also observed a high rate of severe complications including fatal early acute GVHD and VOD, with a higher NRM than expected in a RIC HSCT population. Furthermore, we noted the frequent occurrence of a steroid-responsive febrile syndrome. These possible effects of prior PD-1 blockade (including GVHD, VOD, febrile syndrome) did not appear related to the time from PD-1 treatment to HSCT, and were not reduced by intervening treatment before HSCT. As we accumulate experience with HSCT after PD-1 blockade, our early results may be relevant when considering the decision to proceed to HSCT and for the choice of transplantation strategies. We are presently expanding this analysis through a multi-center international collaborative study. Updated results will be presented at the meeting. Figure 1. Figure 1.

Background: Patients with sickle cell disease (SCD) have reduced life expectancy and high morbidity, despite treatments such as hydroxyurea, transfusion, vaccination, and antibiotic prophylaxis. Both allogeneic hematopoietic stem cell transplant (HSCT) and more recently, gene therapy (GT) via ex vivo manipulation of autologous hematopoietic stem cells (HSC), have emerged as curative strategies for SCD. However, both therapies carry significant risks. HSCT and GT have both demonstrated efficacy against SCD in clinical trials, but have not been compared. Here, we present the updated results of a systematic review comparing HSCT and GT in SCD. Methods: We searched the MEDLINE and EMBASE databases for studies reporting HSCT and GT outcomes in SCD. Phase I-III trials, retrospective reviews, and case reports with &gt;1 SCD patient undergoing HSCT or GT were included. All HSC donor types and conditioning regimens were included. References of included studies were screened for additional relevant studies. All titles/abstracts were screened for full text retrieval. Non-English and preclinical studies were excluded. Primary outcomes were overall survival (OS), event-free survival (EFS), graft failure, transplant-related mortality (TRM), graft-versus-host disease (GVHD), and secondary malignancies. Secondary outcomes were end-organ function, acute chest syndrome/vaso-occlusive episodes (ACS/VOE), and health-related quality of life (HRQOL). We used descriptive statistics to analyze data on study characteristics, quality, and effects. Risk of bias was assessed using the Newcastle-Ottawa Scale. Outcome heterogeneity was assessed using sensitivity and subgroup analyses. Publication bias was assessed with funnel plots, where applicable. Results: We identified 949 titles through database searching and 12 titles from references of included studies (Figure). After removal of duplicate citations (n=147), exclusion of ineligible records (n=716), and merging 42 studies with their primary article, 56 studies were included for data extraction. Of these 56 studies, 53 reported outcomes post-HSCT (n=1149) and 3 reported outcomes post-GT (n=28). Length of follow-up was 3718.6 patient-years and 43.4 patient-years in the HSCT and GT groups, respectively. Median age was 11.5 across HSCT studies; 26/28 GT patients were &gt;18 years. HSCT donor source was matched related donor (n=812), matched unrelated donor (n=73), haploidentical (n=127), or mismatched unrelated donor (n=11) among 1023 HSCT patients. Two-year OS and EFS for HSCT was 91% and 87%, respectively. OS and EFS were not reported for GT studies. TRM was 74/1042 (7.1%) over a median of 3 years of observation for HSCT, and 0/28 (0%) over a median of 1.6 years of observation for GT. Secondary malignancies were reported in 4 SCD patients from the HSCT group and 1 SCD patient from the GT group. While the vast majority of HSCT studies reported the absence of ACS/VOE in engrafted patients, the lack of published data on pre- and post-transplant ACS/VOE frequency precluded further analysis. Median annual ACS/VOE episodes decreased from 5.3 to 0 post-transplant in 1 GT study, while a second GT study reported 2 episodes of ACS and 1 VOE post-GT. Fourteen studies (n=375), all from the HSCT group, reported 6 strokes/TIAs out of 2030.5 patient-years of post-transplant follow-up, with 1/6 strokes occurring in engrafted patients. None of the GT studies explicitly commented on stroke as an outcome. Only 1 study quantified changes in tricuspid regurgitant jet velocity post-transplant, and 1 study reported on renal function pre- and post-transplant, both from the HSCT group. There was no change in pulmonary function testing values post-transplant, as reported by 2 HSCT studies. Post-transplant HRQOL was reported for 8 HSCT studies and 0 GT studies, but due to heterogeneity of reporting, meta-analysis could not be performed. Conclusions: While long-term HSCT and early GT data demonstrate regimen efficacy, reporting of other important post-transplant outcomes such as end-organ function, persistence of SCD-related complications, and patient-important outcomes is lacking for both strategies. Small sample sizes and differential reporting of outcomes preclude comparison between subgroups of HSC sources and conditioning regimens, a limitation of our study. We advocate for standardized reporting to better compare outcomes within and between treatment groups.

Abstract Abstract 2400 Background: Approximately 10% of patients with multiple myeloma (MM) have clinically overt primary systemic light-chain (AL) amyloidosis, and about 30% have concurrent occult AL amyloidosis. The impact of concurrent AL amyloidosis on the prognosis of myeloma is not well known. High-dose melphalan followed by autologous hematopoietic stem cell transplant (auto HCT) has shown significant activity in both MM and AL amyloidosis. Methods: We performed a retrospective analysis of patients who had concurrent MM and AL amyloidosis and underwent auto HSCT with high dose Melphalan at MDACC between 01/1998 to 05/2010. We identified 41 patients with concurrent MM and AL amyloidosis. Patient characteristics are summarized in Table 1. Twenty -six patients had occult AL amyloid, while 15 had clinically overt disease. Results: Median age at auto HSCT was 56 years (39-77), 58.5% being male with median follow up of 58.7 months from the time of diagnosis and 42.5 months from auto HCT. The median time from diagnosis to auto HCT was 8.9 mos (2.7-102.4 mos). 39% had Salmon Durie Stage III disease and 36.6% had more than one involved site at the time of transplant.Cytogenetic abnormalities were detected in 24.4% of patients. Post transplant hematologic responses were as follows: ≥CR=10 (24%), ≥VGPR=16 (39%), >PR=33 (80.5%), ≥stable disease= 40 (97.6%). Among the patients with overt organ involvement, one had early death. Of the 15 evaluable patients, organ responses were scored using the published consensus guidelines for amyloidosis and were as follows: PR=5 (33.3%), ≥SD=7 (46.7%). No correlation was seen between organ response and hematologic response. The 100-day treatment related mortality (TRM) was 0 and 1-year TRM of 2.4% which is comparable to patients transplanted for MM alone at our center. The median progression-free (PFS) and overall survival (OS) from auto HCT were 33.8 and 58.3 months, respectively.The median PFS and OS from diagnosis were 49.8 and 96 mos, respectively. In multivariate analysis, creatinine ≥ 2mg/dl was associated with a shorter PFS (p=0.043) and hemoglobin <10g/dl showed a trend towards a shorter PFS (p=0.093). None of these variables (Hb <10g/dl, Age>60yrs, Creatinine≥2mg/dl, B2M >3.5mg/l, BM plasma cells>30%) emerged as significant predictors of OS. There was no significant difference in outcome between patients with occult or symptomatic AL amyloidosis for OS (p=0.24) or PFS (P=0.9) Conclusion: In this analysis the outcome of patients with concurrent MM and AL amyloidosis was comparable to patients with MM alone. We believe these patients are acceptable candidates for auto HCT.

Abstract Abstract 3150 Background: AL is a plasma cell dyscrasia characterized by the pathologic production of monoclonal light chains which misfold, deposit in various organs, including the heart, and can cause early death. High dose melphalan with stem cell transplant (SCT) results in high hematologic response rates and is a standard treatment for eligible patients. Achieving a complete hematologic response (CR) to SCT results in extended event-free and overall survival (OS), up to 8 and 13 years respectively in one large series. (Blood 2011; 118:4346) We have studied the addition of novel agents as consolidation following risk-adapted SCT (RA-SCT) in order to improve hematologic response (HR) rates and therefore outcomes. (Br J Haem 2007;139:224; Amyloid 2010;17:80a) In this report we examine the long-term outcomes of patients who received initial therapy with RA-SCT followed by consolidation for hematologic response less than CR (HR < CR). Methods: We performed a retrospective study to assess the HR rates, incidence of hematologic progression and overall survival (OS) of AL patients enrolled at diagnosis on two consecutive phase II trials using RA-SCT with consolidation for HR < CR (NCT01527032 and NCT00458822). OS was calculated from date of transplant to date of death or last follow up. Median event free survival (EFS) and OS were estimated by the method of Kaplan Meier. Cumulative incidence function was used to estimate the incidence of progression and death. Results: Between 2002 and 2011, 83 patients were enrolled and underwent RA-SCT on these trials and, following RA-SCT, those with HR < CR received consolidation with thalidomide and dexamethasone (TD) in the first and bortezomib and dexamethasone (BD) in the second trial. Thirty-six patients had cardiac involvement (43%) and all patients had free light chain measurements employed to score hematologic response and progression using consensus criteria (Am J Hematol 2005;79:319; Blood 2010;116:1364a). The frequency of CR following SCT was 24% and increased to 48% with post-SCT consolidation. The CR rates increased at 1 year compared to 3 months post-SCT from 21% to 36% with TD and from 28% to 62% with BD. With a median follow up of 5.1 years, the EFS is 4.5 years (95% CI: 2.6 to not reached) and the OS of all patients has not been reached (Figure 1). Sixteen patients died prior to hematologic progression and 26 patients have progressed with a cumulative incidence of hematologic progression of 8%, 18%, and 29% at 1, 2 and 3 years, respectively (Figure 2). Thirty-one percent (8/26) of relapsed patients have not required second-line therapy while among those who have, 78% (14/18) have responded including 44% (8/18) with CR. The median OS following hematologic progression was 5 years (95% CI: 2.6–5.8). Conclusions: Half of the AL patients on initial therapy trials employing RA-SCT and consolidation for HR < CR achieved CR with 36% of pts on the TD and 62% on the BD consolidation trial in CR at 1 year post-SCT respectively. At 3 years post-SCT the cumulative incidence of relapse was 29% and a third of relapsed patients did not require therapy, likely due to the very sensitive serum free light chain assay that detects low level hematologic progression in the absence of organ progression. Almost 80% of patients requiring second-line therapy responded, over half with CR, and median OS after relapse was 5 years. These results indicate that initial therapy with RA-SCT and consolidation is an effective initial treatment strategy for patients with AL in the era of novel agents. With over 5 years of follow up the median OS has not been reached.

Abstract Background: Len maintenance after autoHCT has improved progression-free (PFS) and overall survival (OS). However, the role of additional interventions after autoHCT such as tandem autoHCT or triple therapy consolidation remains to be determined. Methods: This is a phase III clinical trial (NCT#01109004) of transplant-eligible patients (pts) with symptomatic MM <71 years of age within 12 months of initiating therapy and without prior progression who were randomly assigned 1:1:1 to receive melphalan 200mg/m2 autoHCT and 4 cycles of RVD consolidation (lenalidomide 15mg daily days 1-14, dexamethasone 40mg day 1,8 and 15, and bortezomib 1.3mg/m2 days 1,4,8 and 11 every 21 days) (ACM), versus tandem melphalan 200mg/m2 autoHCT (TAM) or versus a single autoHCT (AM). Randomization was stratified by disease risk (cytogenetic abnormalities - del13q by karyotype, del17q, t(4;14), t(14;16), t(14;20) and hypodyploid; or high beta-2 microglobulin) and center. All arms included Len maintenance (at maximum tolerated dose of 5 to 15 mg orally daily until progression) with dose modifications for toxicities. All patients were reviewed centrally for eligibility, response and progression. The primary objective was to compare 38-month PFS of the three arms. The events for PFS included progression, non-protocol anti-myeloma therapy, or death. Comparisons between treatment groups were based on pairwise log-rank tests stratified on disease risk, with significance levels adjusted for the 3 pairwise comparisons and for interim analyses. In calculating the cumulative incidence of progression, the events were progression or non-protocol anti-myeloma therapy, and death was a competing risk. Results: From June 2010 to November 2013, 758 pts (ACM, N=254; TAM, N=247; AM, N=257) aged 20-70 years (median 57y) were enrolled. Of those enrolled, 24% were classified as high risk. Non-compliance rates following the first autoHCT were 12%, 32% and 5% for ACM, TAM and AM, respectively. Median available follow up from randomization was 38 months. Follow-up is continuing through January 2017. 38-month estimated probabilities for PFS were 57% (95% CI: 50-63%), 56% (95% CI: 49-63%) and 52% (95% CI: 45-59%) for ACM, TAM and AM, respectively (ACM vs TAM p=0.75, ACM vs AM p=0.21, TAM vs AM p=0.37). Corresponding probabilities of OS were 86% (95% CI: 80-90%), 82% (95%CI: 76-87%) and 83% (95% CI: 78-88%). Median OS has not been reached. Cumulative incidences of disease progression at 38 months were 42% (95% CI: 36-48%), 42% (95% CI: 35-48%) and 47% (95% CI: 40-54%) for the ACM, TAM and AM arms, respectively. There were 39 cases of second primary malignancy (SPM) reported in 36 participants and the cumulative incidences for first SPM were 6.0% (95% CI: 3.4-9.6%), 5.9% (95% CI: 3.3-9.6%) and 4.0% (95% CI: 1.9-7.2%) for the ACM, TAM, and AM, respectively. Conclusions: The primary results of the largest randomized US transplant trial in MM demonstrated comparable PFS and OS. The addition of RVD consolidation or a second auto-HCT was not superior to a single auto HCT followed by Len maintenance in the upfront treatment of MM. A long term follow-up trial to track outcomes in these patients is ongoing.
