Background High dose chemotherapy followed by an autologous stem cell transplant (auto-HCT) is considered standard of care in patients with newly diagnosed multiple myeloma (MM). In a recent randomized trial, median progression free survival (PFS) after auto-HCT, with or without maintenance therapy was 46 and 27 months, respectively (McCarthy P et al. NEJM 2012). However, about 15% of patients are reported to have much longer PFS (Pineda-Roman M et al. Cancer 2008). Here we tried to identify the factors that may predict a long PFS after auto-HCT. Methods We performed a retrospective chart review of patients who received an auto-HCT for MM between January 2000 and March 2007. A total of 1135 patients underwent an auto-HCT during this period, and 194 patients (17%) had a minimum PFS of 72 months or longer after a single auto-HCT. The primary objective was to determine the variables associated with a long PFS and overall survival (OS). Results Patient characteristics and outcomes are shown in the attached Table. The median age at auto-HCT was 56 years, and the median time from diagnosis to auto-HCT was 7.5 months. Twenty-three (13%) patients had ≥ 10% plasma cells in the bone marrow at auto-HCT and only 9 patients (4.8%) had high-risk cytogenetic abnormalities. One-hundred and fifty (77%) patients received induction therapy containing either an immunomodulatory (IMiD) agent or a proteasome inhibitor (PI). At the time of the auto-HSCT, only 13 (6.7%) patients were in CR and 38 (19.6%) were CR or VGPR after induction therapy (Table). One-hundred and sixty three (84%) patients received mephalan alone as conditioning regimen. Eighty-one (42%) patients received post auto-HCT maintenance. Eighty (41%) patients achieved a CR, while 104 (54%) achieved CR + VGPR after auto-HCT. Six patients (3.1%) developed a second primary malignancy post- autologous transplant. After a median follow-up of 95.4 months, median PFS was 97.3 months and median OS has not been reached. The 10-year PFS and OS were 41% and 73% respectively. Use of melphalan alone as preparative regimen was associated with a longer PFS and OS (p=0.004 and 0.004, respectively). Achievement of CR after auto-HCT was associated with a longer PFS only (p=0.001), and the use of IMiD or a PI as induction was associated with a longer OS (p=0.01). Conclusion Approximately 17% patients achieved a median PFS of 6 years or longer after a single auto-HCT. The long PFS in this cohort may be associated with younger age, low incidence of HR cytogenetics, use of an IMiD or PI as induction therapy, relatively low disease burden at auto-HCT, transplant from the year 2000 onwards, achievement of CR in >40% and the use of melphalan alone as preparative regimen.

Abstract BACKGROUND Survival rates in multiple myeloma (MM) have significantly improved in recent decades with the advent of high-dose chemotherapy conditioned autologous stem cell transplantation (ASCT) and the availability of novel agents for induction therapy (Kumar SK et al. Blood 2008). Failure to respond to front-line bortezomib-based induction therapy remains a significant clinical challenge in transplant eligible (TE) newly diagnosed multiple myeloma (NDMM), and is associated with poor outcomes with shortened progression free survival (PFS) and overall survival (OS) (Lee SE et al. Ann Hematol. 2014). In combination with immunomodulatory agents (IMiDs), carfilzomib, a second generation proteosome inhibitor, has been shown to be highly effective in the context of MM induction with high rates of negativity for minimal residual disease (MRD) and few dose limiting toxicities (Langren O et al. Leukemia 2019). The ALLG MM17 trial is a multicentre single arm study of carfilzomib-thalidomide-dexamethasone (KTd) in TE NDMM patients refractory or with suboptimal response to bortezomib-based induction therapy, designed to evaluate the efficacy of early response adaption with a switch to an intensive salvage strategy. METHOD Eligible patients included those with TE NDMM, aged 18 years and older, demonstrating sub-optimal response to bortezomib-based induction therapy (failure to achieve a minimal response after 2 cycles, partial response [PR] after 4 cycles, or disease progression within 60 days of completing induction). Salvage therapy consisted of 100mg daily oral thalidomide, with 20 mg of oral dexamethasone and 20mg/56mg of IV carfilzomib on days 1, 2, 8, 9, 15, and 16, with of each 28-day cycle. Following 4 cycles, patients in stringent complete response (sCR) proceeded to melphalan conditioned ASCT whereas those in less than sCR received a further 2 cycles of KTd prior to ASCT. Consolidation therapy consisted of a further 2 cycles of KTd, followed by maintenance 100mg daily thalidomide and 40mg weekly dexamethasone (Td) continuing until progressive disease, unacceptable toxicity, or 12 months of therapy. Primary objectives were to determine the overall response rate (ORR) and safety profile of treatment with KTd salvage therapy, with secondary objectives to determine the maximal depth of response, progression free survival (PFS), and overall survival (OS) achieved with sequential treatment with KTd salvage, ASCT, post-ASCT consolidation, and maintenance Td therapy. Efficacy assessments were performed via serum protein electrophoresis, serum free light chain and bone marrow evaluation. Next generation flow (NGF) cytometry MRD evaluation of bone marrow aspirate was undertaken pre-ASCT, at day 100 post-ASCT, after 2 cycles of consolidation KTd, and following completion of Td using standardized 8-colour EuroFlow platform. RESULTS 50 patients were recruited across 6 Australian sites between September 2016 and April 2018. Overall response rate to KTd salvage was 78% (Credible Interval 95%: 64.4-87.1%), with dual proof of concept criteria met (observed ORR ≥ 50% and posterior probability that the true ORR exceeds 30% is ≥ 0.90). Response rates included 12% sCR, 6% CR, 38% VGPR, and 22% PR. Sixteen patients discontinued treatment (32%) including 10 cases (20%) of progressive disease, and 2 patient deaths without progression. NGF MRD negativity was found to be 32%, 36% and 55% at the pre-ASCT, post-ASCT and post-consolidation time-points. At the cut-off date, estimated median follow-up for disease status was 38.6 months and median PFS and OS had not been reached. At 36 months PFS and OS were 63.9% (95%CI: 49.0 - 75.5%) and 79.9% (95%CI: 65.8 - 88.6%) respectively (Figure 1). KTd was found to be well tolerated with 44% of patients experiencing a grade 3 of higher adverse event (AE). Most common AEs included upper respiratory infection (48%), peripheral neuropathy (36%), musculoskeletal pain (32%), dyspnoea (28%), fatigue or lethargy (28%), and constipation (28%). Significant cardiac toxicity was not observed at this higher dose level of carfilzomib. CONCLUSION Results demonstrate that response-adaptive utilisation of KTd salvage, ASCT, and consolidation therapy induces high response rates, improving depth of response with high levels of sequential MRD negativity, and durable responses with an acceptable toxicity profile in TE NDMM patients failing bortezomib-based induction therapy.

Abstract Background: Induction therapy prior to consolidation with autologous stem cell transplantation (ASCT) continues to improve with the use of proteasome inhibitors and imids and combination regimens such as RVD. Bortezomib-based induction therapy has improved overall response rates (ORR) prior to transplant, which has translated to improvements in ORR and progression free survival post ASCT. However, complete remission (CR) rates with RVD remain low (10-15%) after 4 cycles of induction therapy. Panobinostat, a histone deacetylase inhibitor, in combination with bortezomib/dexamethasone, has demonstrated a significant improvement in depth of response and progression free survival in patients (pts) with relapsed myeloma as seen in PANORMA I. Preclinical data demonstrate synergy between the combination of bortezomib and panobinostat. We undertook a phase I/Ib trial in pts with newly diagnosed myeloma (NDMM) of RVD + Panobinostat to establish the safety of the combination and goal of improving the depth of response with induction therapy prior to ASCT. Methods: The primary objective was to determine the maximum tolerated dose (MTD) and safety/tolerability of RVD + panobinostat in NDMM. Secondary objectives were to determine efficacy as measured by the CR/nCR rate after 4 cycles, ORR, tolerability/toxicity, and progression free survival. Pts had to have NDMM with indication for therapy, candidates for ASCT with and had adequate organ function. Panobinostat was administered on days 1, 3, 5, 8, 10, 12; bortezomib 1.3 mg/m2 was administered subcutaneously on days 1, 4, 8, 11; lenalidomide 25 mg on days 1-14; dexamethasone 20 mg on days 1, 2, 4, 5, 8, 9, 11, and 12 on a 21 day cycle. Dose-escalation of panobinostat used a standard 3+3 schema with dose-limiting toxicities (DLTs) assessed during cycle 1. Three dose levels were studied with Panobinostat escalated from 10 to 20 mg. Adverse events (AEs) were graded by NCI-CTCAE v4, while responses were assessed by the modified International Uniform Response Criteria. Results: 22 pts were enrolled; 12 pts in the completed phase 1 dose escalation portion of the study and 10/20 in the ongoing dose expansion. The median age was 61 (range 53-79); ISS stage I 12; stage II 7/20; stage III in 3/20 pts. No DLTs were observed in 3 pts dosed in cohort 1, with Panobinostat at 10 mg. In cohort 2, panobinostat was dosed at 15 mg, 2/6 pts encountered a DLT. One patient experienced Grade 4 (G4) thrombocytopenia, and the second patient had G3 diarrhea without supportive measures, for <12 hours and resolved with supportive measures. In cohort 1, 3 additional patients were enrolled and no DLTs were encountered in the remaining 3 pts. The final recommended dose was Panobinostat 10 mg in combination with RVD in NDMM. Treatment emergent SAEs related to therapy observed in 5 pts with 2 incidences of G3 diarrhea; 2 pts with atrial fibrillation; and other events included G4 thrombocytopenia; G3 bacteremia, G3 cellulitis, G3 myocardial infarction (MI), G3 pulmonary emboli; G3 pneumonia. Hematologic adverse events G3/4 included anemia 3/22; neutropenia 4/22; thrombocytopenia 7/22. G3/4 nonhematologic toxicities included ALT elevation (n=2); AST elevation (n=1); constipation (n=2); diarrhea (n=2); fatigue/muscle weakness (n=2); MI (n=1); pneumonia (n=3). Among 18/22 pts who have completed 4 cycles of therapy and are evaluable for efficacy, the ORR (≥PR) was 100%: including nCR/CR in 5/18 (28%), VGPR in 5/18 (28%), PR in 8/18 (44%). Conclusions: MTD has been established at level 1, with panobinostat 10 mg and full dose RVD in NDMM. The DLTs were diarrhea (irrespective of supportive care) and thrombocytopenia. This is the first experience with panobinostat and subcutaneous bortezomib and first experience in combination with RVD. The combination is well tolerated with limited toxicity and side effects can be managed with supportive care. The preliminary activity after 4 cycles of therapy demonstrated a high ORR of 100% and a promising depth of response with a nCR/CR of 27%. Enrollment in a dose expansion cohort is near completion and full data will be presented at ASH.

Abstract Background: Multiple myeloma (MM) remains an incurable disease, but deep, lasting remission can be achieved with induction therapy and autologous stem cell transplant (ASCT). The current ASCT treatment timeline includes a gap between the end of induction and the day of ASCT to permit correct mobilization and collection of stem cells. During this interval, some patients experience increases in their MM markers. We specifically evaluated if patients with interval progression (IP) have different outcomes post-ASCT compared to patients without IP. Methods: We completed a retrospective analysis of 482 patients who underwent ASCT at The Ohio State University Wexner Medical Center between 2011 and 2016. MM labs, including protein electrophoresis with immunofixation and free light chains, were obtained at day of diagnosis, end of induction, and day of ASCT. A 20% increase in the index protein between the end of induction and the day of ASCT was defined as IP. The primary outcomes evaluated were time-to-progression (TTP), progression-free survival (PFS), and overall survival (OS). TTP was defined as time from ASCT to disease progression, treating death without progression as a competing risk. PFS was defined as the time from ASCT until either disease progression or death, while OS was defined as the time from ASCT until death or last follow-up. Poisson regression models with robust variance were used to evaluate the associations between patients' characteristics and IP, while competing risk regression models were used for TTP analysis, and Cox regression models for OS and PFS analysis. Results: 482 patients who underwent ASCT for MM between 2011 and 2016 were studied. The patient population was primarily male (n = 296, 61.4%), Caucasian (n = 420, 87.1%), and had IgG disease (n = 269, 55.8%). MM stage at diagnosis was equally represented. Cytogenetic analysis showed 108 (22.4%) patients with 1q21 amplification, 60 (12.4%) patients with t(11;14) translocation, 33 (6.8%) patients with t(4;14) translocation, and 40 (8.3%) patients with 17p deletion. More than 80% of patients underwent maintenance therapy following ASCT. One hundred and fifty-six (32.3%) patients were defined as having IP. Patients in the IP group were significant more likely to have LC disease (p = 0.0018), but no other patient characteristics varied significantly between the two groups. LC disease (relative risk (RR adj) = 2.12, 95% CI 1.37-3.30, p = 0.001) and deletion 17p (RR adj = 1.62, 95% CI 1.08-2.42, p = 0.02) were associated with increased risk of IP on multivariate analysis (MVA). Five-year PFS rates were 47.2% and 36.8% in the non-IP and IP groups, respectively. Five-year cumulative progression rates were 49.0% in the non-IP group and 57.8% in the IP group. Five-year OS rates were 76.8% in the non-IP group and 69.6% in the IP group. On univariate analysis (UVA), IP correlated with inferior outcomes in both TTP (hazard ratio (HR) = 1.39, p = 0.01) and OS (HR = 1.39, p = 0.04). In agreement with previous literature, other factors independently correlated with inferior TTP and OS outcomes, including MM stage, cytogenetics (amp1q, t(4;14), and del(17p)), and absence of maintenance therapy post-ASCT. On MVA, IP was no longer significantly associated with a shorter TTP (HR = 1.16, p = 0.35), but approached statistical significance in conferring inferior OS (HR = 1.40, p = 0.07). Notably, once deletion 17p was removed from the MVA, the presence of IP once again conferred significantly lower OS (HR = 1.45, 95% CI 1.01-2.07, p = 0.04), suggesting that deletion 17p, which is a significant risk factor for both IP and OS, may mediate the effect of IP. Combined, all data suggest that uncontrolled disease prior to ASCT trends towards worse long-term outcomes. Conclusion: In this study, we report the first data regarding patients who experienced rapid disease progression in the interval between induction therapy and ASCT. These patients have inferior TTP, PFS, and OS, likely due to the presence of LC disease or deletion 17p. IP may provide a valuable predictor of robustness of response to ASCT and prompt the need for additional induction cycles or alternative regimens. This is especially relevant for patients with deletion 17p. Indeed, these data support a prospective study of concepts to improve outcomes for patients with IP prior to ASCT.

Introduction: There is a paucity of randomized trials to guide therapy for relapsed AL amyloidosis with treatment regimens generally extrapolated from experience in multiple myeloma. Methods: We conducted a retrospective review of patients who relapsed after receiving autologous stem cell transplant at Mayo Clinic. Patients treated for first relapse between January 2004 and December 2018 were included. Results: Three hundred and twenty-one patients were seen for relapsed AL amyloidosis post ASCT during the study period. Baseline characteristics were typical for a cohort with AL amyloidosis and are listed in Table1. 39% received therapy prior to transplant, conditioning in the majority (75%) was melphalan 200mg/m2. The median progression free survival from transplant (PFS1) was 30.7 months. Of the 321 patients 294 received treatment for relapsed disease. We categorized treatment regimens according to commonly used combinations and drug classes to further analyze outcomes. 34 patients were excluded from this analysis as they either proceeded directly to second ASCT (n=10) or received an atypical regimen not commonly considered for AL amyloidosis (n=24). Five categories of therapy regimens were identified, thalidomide based (n=110), melphalan plus steroids (n=31), 2nd generation immunomodulatory (IMiD) drug +/- alkylator (n=76), proteasome inhibitor (PI) +/- alkylator (n=116), PI plus IMiD (n=16), or daratumumab based (n=9). Disease and treatment characteristics for patients treated with these regimens are listed in Table 2. Patients treated with thalidomide had the shortest PFS1 (17.7 months) but PFS1 was similar for those treated with melphalan plus steroids, PI+IMiD and 2nd generation IMiDs (25.5, 24.3 and 25.6 months respectively). Patients treated with a PI +/- alkylator and daratumumab based regimen had the longest PFS1 (36.7 and 41.9 months respectively). The median duration of therapy was longer in patients treated with a 2nd generation IMiD or daratumumab based regimen (10.2, 12, 6.1, 5.5, 6.2 and 5.9 months for Dara based, 2nd generation IMiD, PI+/- alkylator, PI+IMiD, melphalan plus steroids and thalidomide based respectively). Hematologic response rate was lowest in those treated with melphalan plus steroids or thalidomide based regimens (44% and 55% respectively) and highest for patients treated with a PI+/- alkylator, (Figure 1). Progression free survival from relapsed therapy (PFS2) was longest amongst patients treated with daratumumab based regimens, PI +/- alkylator and 2nd generation IMiDs (not reached, 29.9 and 26.7 months respectively), Figure 2A. Overall survival from time of relapsed therapy favored patients treated with daratumumab based regimens, 2nd generation IMiDs and PI +/- alkylator, Figure 2b). Conclusion: A second generation IMiD based regimen or PI +/- alkylator produce high response rates and prolonged progression free and overall survival for relapsed AL amyloidosis. Patients treated with daratumumab based regimens and those treated with a PI plus IMiD also appear to do well, although numbers were low in our study. Patients treated with melphalan plus steroids or thalidomide based combinations have inferior outcomes and these regimens should be avoided.

Abstract Introduction Large clinical data sets suggest that the natural history and prognosis of newly diagnosed multiple myeloma (NDMM) differs between patients of European and African ancestry, with the latter group exhibiting an earlier age at onset and poorer overall prognosis in some studies. The use of next generation sequencing (NGS) to characterize the genomic landscape of multiple myeloma (MM) suggests that the observed phenotypic differences between these groups of patients may reflect distinct underlying genomic profiles and mutational processes. Thus far, characterizations of this type have focused principally on patients of African ancestry (AA). Here, we characterize the genomic features and outcomes of a large series of patients of Hispanic or Latin American ancestry (HL) as compared to their Non-Hispanic white (NHW) counterparts. Methods Subjects were selected from the MMRF CoMMpass SM trial, a study that includes 1,154 patients with updated outcome data as of March, 2020. Within this data set, 760 patients had information on race and ethnicity. Among these, 55 HL patients and 478 NHW patients possessed complete clinical and genomic information. We analyzed baseline whole exome sequencing (WES) and long insert whole genome sequencing (WGS) as previously described (Walker, et al. Blood 2019). Our analysis focused on 63 known driver mutations in multiple myeloma and 39 sites of common copy number variation across the study population. Complex structural variants and tumor telomere length were called using previously described bioinformatic tools (Boyle et al. Leukemia 2021). Survival analysis was undertaken using the Kaplan-Meier method with hazard ratios determined by the Cox proportional hazards model. Results In a comparison of clinical features between the Hispanic and NHW population, we did not identify any differences in age of onset, gender, presenting cytogenetics, International Staging System Score (ISS), and IMWG Risk Category. The proportion of patients undergoing autologous stem cell transplantation was similar between groups. We identified no statistically significant differences in the presence of characteristic translocations involving IgH locus or in hyperdiploidy status. No statistically significant differences in tumor mutational burden or loss-of-heterozygosity percentage emerged between HL and NHW patients. We examined non-synonymous variations (NSV) and copy number variations at the loci of known MM driver genes and encountered no statistically significant differences in NSV, copy number, or biallelic status. We further categorized genes into pathways relevant to the pathogenesis of MM and discovered no difference in the proportions of patients harboring mutations in genes related to the MEK/ERK and NF-κB pathways, cell cycle regulation, and epigenetic modification. We were unable to the distinguish either population based on the presence of chromothripsis or in the overall preponderance of an APOBEC mutational signature. Tumor telomere length was not significantly different between the populations. An analysis of overall and progression free survival (PFS) with a median duration of follow up of 44 months revealed a trend toward poorer outcomes among the HL population that did not reach statistical significance. Median PFS was 24 months in HL patients and 35 months in the NHW population (p = 0.19). Median OS was not reached in either ethnic subgroup. In terms of overall survival, age, ISS score, overall number of driver mutations, and the presence of chromothripsis emerged with a negative impact on outcome (Figures 1a, 1b). These variables with the exception of chromothripsis retained their significant impact on progression free survival (Figure 2a, 2b). Conclusion The correlation between Hispanic or Latin American ancestry and underlying disease biology in MM has yet to be fully elucidated. In our analysis, which was based on self-declared ancestry as opposed to admixture, no obvious differences in significant measures of genomic variation known to impact prognosis in MM emerged between HL and NHW patients. These results may help to inform the future large-scale studies to ascertain the impact of genomics, disease biology and socioeconomic factors on outcomes in this heterogeneous patient population.

Abstract Introduction: Daratumumab is an anti-CD38 IgGκ monoclonal antibody that has been combined successfully with lenalidomide and dexamethasone. The combination of daratumumab with lenalidomide and dexamethasone (DRd) has been compared with lenalidomide and dexamethasone alone (Rd) in patients (pts) with relapsed or refractory multiple myeloma (RRMM) in a randomized phase 3 study (Dimopoulos MA, et al. N Engl J Med 2016; in press). In a pre-specified interim analysis, the DRd combination demonstrated significantly longer progression-free survival (PFS) in addition to deep and durable responses compared with the Rd arm. We performed subgroup analyses to further examine these efficacy data according to prior treatment exposure. Methods: Pts who received ≥1 prior line of therapy were randomized (1:1) to Rd (lenalidomide: 25 mg PO on Days 1-21 of each 28-day cycle; dexamethasone: 40 mg PO weekly) with or without daratumumab (16 mg/kg IV qw for 8 weeks, q2w for 16 weeks, then q4w until progression). The primary endpoint was PFS. Pts who were refractory to lenalidomide were not eligible. All analyses were performed in pts who received 1 to 3 prior lines of therapy. Results: Median follow-up was 13.5 months. Pts who were lenalidomide-naive prior to the start of study treatment (DRd, n=226; Rd, n=219) demonstrated significantly longer PFS with DRd vs Rd (median: not reached [NR] vs 18.4 months; HR, 0.36; 95% CI, 0.25-0.52; P<0.0001), with estimated 12-month PFS rates of 83.0% vs 59.9%, respectively. ORR was significantly higher with DRd vs Rd (96% vs 79%), with ≥VGPR rates of 76% vs 47% and ≥CR rates of 44% vs 21%, respectively (P<0.0001 for all). In the lenalidomide-exposed subgroup (DRd, n=46; Rd, n=45), median PFS was NR in both treatment groups (HR, 0.49; 95% CI, 0.22-1.12; P=0.0826); estimated 12-month PFS rates were 84.1% vs 63.1%, respectively. ORR was higher with DRd vs Rd but did not reach statistical significance (87% vs 71%; P=0.0729); however, rates of ≥VGPR (78% vs 38%; P=0.0001) and ≥CR (44% vs 12%; P=0.0011) were significantly improved with DRd vs Rd, respectively. For bortezomib-naive pts (DRd, n=44; Rd, n=45), PFS was significantly longer with DRd vs Rd (median: NR vs 15.8 months; HR, 0.34; 95% CI, 0.13-0.86; P=0.0170), with estimated 12-month PFS rates of 85.4% vs 69.2%, respectively. ORR was significantly higher with DRd vs Rd (98% vs 82%; P=0.0158), with trends toward increased rates of ≥VGPR (74% vs 55%; P=0.0544) and ≥CR (42% vs 23%; P=0.0576). In the bortezomib-exposed pts (DRd, n=228; Rd, n=219), median PFS was NR in DRd vs 18.4 months in Rd (HR, 0.35; 95% CI, 0.24-0.50 P<0.0001); estimated 12-month PFS rates were 82.8% vs 58.7%, respectively. Significant differences in ORR (93% vs 77%), rate of ≥VGPR (77% vs 43%) and rate of ≥CR (44% vs 19%) were observed with DRd vs Rd, respectively (P<0.0001 for all). Among bortezomib-refractory patients (DRd, n=54; Rd, n=49), the PFS benefit of DRd compared with Rd was maintained (median: NR vs 10.3 mo, respectively; HR, 0.46; 95% CI, 0.25-0.85; P=0.0117; Figure). The estimated 12-month PFS rates were 70.8% vs 44.4%, respectively. Similar to bortezomib-exposed pts, ORR (92% vs 68%; P=0.0024), rate of ≥VGPR (75% vs 36%; P=0.0001), and rate of ≥CR (46% vs 13%; P=0.0003) were all significantly higher with DRd vs Rd for bortezomib-refractory pts. Updated data will be presented at the meeting. Conclusions: Among pts who received 1 to 3 prior lines of therapy, significantly longer PFS and higher ORR were observed with DRd vs Rd among pts who previously received bortezomib or were refractory to bortezomib or were lenalidomide-naive. Higher rates of deeper responses were observed in pts who previously received lenalidomide or bortezomib. Follow-up is ongoing to assess PFS in pts who received 1 to 3 prior lines of therapy and previously received lenalidomide. These results further strengthen the significant benefit of combining daratumumab with Rd for RRMM.

Abstract Abstract 1878 Poster Board I-900 Autologous stem cell transplant as a platform for multiple myeloma treatment is the standard of care for patients who can safely withstand the procedure. Before novel agents were introduced, one-third to one-half of patients did not achieve partial response at transplant. Previously published medical literature has showed that in this past era, absence of initial response to induction therapy had no impact on progression-free survival and overall survival after high-dose therapy. Lack of response to initial induction did not preclude a good response after stem cell transplant. With the introduction of novel agents—immunomodulatory drugs and proteasome inhibitors—response rates with initial therapy are now between 70% and 100%. This retrospective study analyzes progression-free survival and overall survival in patients who do not have a partial response after induction therapy with a regimen that contains a novel agent. Unlike patients in reports published previously—before novel agents—patients who do not achieve partial remission have a significantly shorter overall survival from transplant (74.0 vs 43.5 months) and a shorter progression-free survival (22.6 vs 13.1 months; P<.001). Absence of a response to induction therapy with a novel agent predicts a poorer outcome after high-dose therapy.{abstabft}.b CR+VGPR for plateau, P<.001 compared with other 3 categories. Failure to respond to novel-agent induction leads to shorter posttransplant progression-free survival (PFS).

Refractory Multiple Myeloma

Abstract Background Relapsed and refractory multiple myeloma (RRMM) remains a major challenge. With each relapse, patients (pts) experience decreased response duration leading to shortened survival. Pts with triple-class refractory disease (refractory to one class of the following: immunomodulatory agents (IMiDs), proteasome inhibitors (PI) and anti-CD38 monoclonal antibody) have a poor prognosis. Belantamab mafodotin is a first-in class B-cell maturation antigen (BCMA) antibody-drug conjugate. The aim of this study was to analyze the clinical outcomes of belantamab/dexamethasone (Bd) in triple-class RRMM. Patients & Methods Twenty-eight pts with triple-class RRMM receiving Bd were identified at University of Kansas Health System between October 2019 and June 2021 and reviewed retrospectively. These pts received belantamab 2.5 mg/kg IV every 3 weeks and dexamethasone (20-40) mg PO weekly. Descriptive analyses were performed on available data for patient characteristics. Survival curves were generated using the Kaplan-Maier method. Responses were evaluated using the International Myeloma Working Group (IMWG) criteria. Results The median age was 67 yrs (42-85). Eleven pts (39%) had IgG isotype, 14 pts (50%) had R-ISS stage III disease, 20 pts (71%) had high-risk cytogenetics, and 13 pts (46%) had extramedullary disease (EMD). Patients characteristics are summarized in Table 1. Median number of Bd cycles received was 3 (2-18). The median number of previous lines of therapy was 5 (3-15). All pts were triple-class refractory, whereas 15 pts (54%) were penta-refractory. Twenty-one pts (75%) received autologous stem cell transplant, and 8 pts (29%) had previously received BCMA-targeted therapy. The response rate for all pts was 46% with 18% achieving very good partial response and better. Median follow-up was 7.4 months. Median progression-free survival (PFS) was 4.9 months, while median overall survival (OS) was 7.4 months. The response rates are summarized in Table 2. Keratopathy was one of the most common adverse events (AEs), occurring in 23 (82%) pts, 13 (56%) pts had grade 3 or 4 keratopathy. Nineteen patients (68%) required dose reduction or delay due to keratopathy. Other common AEs included: anemia (83%), thrombocytopenia (70%), neutropenia (30%), and elevated liver function tests (53%). Eighteen patients (64%) discontinued due to progression of disease or death. No treatment-related mortality was noted in this review. Conclusion Our analysis demonstrates a reasonable efficacy of Bd in those who are heavily treated triple-class RRMM patients in the real world. Keratopathy remains a challenging AE and the main cause of dose reduction and delay. Figure 1 Figure 1.

Abstract Introduction While 50-60% of patients with diffuse large B-cell lymphoma (DLBCL) are cured with initial chemoimmunotherapy such as R-CHOP, many patients will relapse and require additional therapy. Historically, autologous stem cell transplant (ASCT) has been utilized in chemo-sensitive patients with relapsed DLBCL although the role of ASCT in patients who require > 1 salvage treatment to achieve remission is less defined due to concerns about the likelihood of long-term remission in that population. We evaluated the outcome of ASCT in patients who required >1 salvage therapy. Methods We included all patients undergoing ASCT for relapsed/refractory DLBCL at our site between 2005-2016 who received > 1 salvage treatment before transplant, with radiation therapy considered a salvage treatment if given after relapse but before ASCT. We collected demographic, clinical, laboratory and pathologic data on all patients. We defined progression-free survival (PFS) as time from ASCT to date of progression or death from any cause and overall survival (OS) as time from ASCT to date of death from any cause. Living patients were censored at the time of their last follow up. Univariate Cox proportional hazards models of PFS and OS were fit and Kaplan-Meier plots were developed to estimate the impact of variables of interest on survival. Results Out of 259 patients undergoing ASCT for DLBCL, 43 received > 1 salvage treatment, the median age was 51 years and 23 patients were male. Twenty patients had stage III/IV disease at diagnosis. The median time to relapse from the time of diagnosis was 9.3 months, and 42% of patients experienced a relapse > 12 months after diagnosis. Twenty-six patients (60%) received radiation as one of their salvage therapies, 25 patients (58%) received R-ICE as their first salvage therapy and 10 (23%) patients received R-ICE as their second salvage treatment. All patients received either 2 (n=39) or 3 (n=4) salvage therapies before ASCT, and the response to the initial salvage therapy received was CR in 4 patients, PR in 14 patients, SD in 1 patient, and PD in 14 patients, with initial response to salvage therapy missing in 10 patients. The median PFS for all patients was 15.9 months and the median OS was 57.2 months (Figure 1a). Receipt of radiation and having disease sensitive to treatment at the time of ASCT were the only factors associated with prolonged PFS and OS. Median PFS has not been achieved in patients who received radiation while patients who did not receive radiation had a median PFS of 4.2 months (HR = 0.36, p = 0.014; Figure 1b). Patients who had a chemo sensitive disease status at transplant had a median PFS of 22.6 months; however, patients with refractory disease at transplant only achieved a median PFS of 3.6 months (HR = 0.30, p=0.008). Remaining factors including conditioning regimen, time to relapse, and number of salvage therapies were not significantly associated with PFS or OS. Conclusions ASCT can result in prolonged PFS/OS in patients requiring > 1 salvage therapy especially in the case of sensitive disease. Radiation as an additional line of therapy is associated with improved PFS/OS, suggesting this can be included to induce remission in patients who fail to achieve CR with initial salvage treatment. While uncommon, patients with chemo-refractory disease can also have durable survival and should not be excluded from transplant.
