Prognostic Utility

Introduction : We have previously shown that a clinicogenetic risk model called the m7- Follicular Lymphoma (FL) International Prognostic Index (m7-FLIPI), which includes the mutation status of 7 genes (EZH2, ARID1A, MEF2B, EP300, FOXO1, CREBBP, and CARD11), the FLIPI, and the ECOG performance status improves risk stratification in patients with advanced stage FL receiving frontline immunochemotherapy (Pastore, 2015). The m7-FLIPI was trained on a group of patients treated with R-CHOP and validated on an independent cohort treated with R-CVP. The aim of this study was to test the prognostic utility of the m7-FLIPI in patients treated within the GALLIUM trial. The GALLIUM trial enrolled 1202 patients with FL randomized to either receive Rituximab (R)- or Obinutuzumab (GA101, G)-based frontline treatment (Marcus, 2017). The chemotherapy consisted either of CHOP, CVP or Bendamustine and was allocated by the treating study center. All patients had previously untreated FL, advanced stage disease (stage III/IV or stage II with bulky disease) and ECOG performance status 0-2. All patients required treatment according to the GELF criteria. Methods: We performed targeted DNA sequencing of recurrently mutated genes, including the m7-FLIPI genes from diagnostic FL biopsies. We excluded cases with no available biopsies, insufficient DNA quantity/quality, or if patients did not sign informed consent for molecular studies. 418 patients were available for evaluation of the m7-FLIPI. The m7-FLIPI was calculated as previously described (http://www.glsg.de/m7-flipi/). Investigator-assessed progression-free survival (PFS), the primary endpoint in the GALLIUM trial, was the primary endpoint of this analysis. We performed Kaplan-Meier estimation and Cox proportional hazards regression to test the prognostic utility of the m7-FLIPI. The median follow up in the evaluable cohort was 4.7 years. 283 patients (68%) received Bendamustine (140 R, 143 G), 111 (27%) received CHOP (52 R, 59 G), and 24 (6%) received CVP (12 R, 12 G). Results : 104 patients (25%) had high-risk m7-FLIPI. 90 out of 194 patients with high-risk FLIPI (46%) were reclassified as low-risk by the m7-FLIPI. High-risk m7-FLIPI was associated with shorter PFS in the overall cohort (HR 1.52, P=0.030). Likewise, the m7-FLIPI was prognostic in patients treated with R-based regimens (HR 1.67, P=0.037). However, it was not prognostic in patients treated with G-based regimens (HR 1.24, P=0.49). When analyzed by different chemotherapy regimens, the m7-FLIPI was prognostic in patients receiving CHOP/CVP-based treatment (HR 2.05, P=0.013), validating the results from our original publication. The m7-FLIPI outperformed the FLIPI (HR 1.34, P=0.31) and had a significantly higher C-index (m7-FLIPI C=0.69, FLIPI C=0.57, P=0.021). However, the m7-FLIPI was not prognostic in patients receiving Bendamustine-based treatment (HR 1.23, P=0.42). Within the m7-FLIPI, mutations in EZH2 have the highest weight of all gene mutations. In this study, we found EZH2 mutations in 93 cases (22%). EZH2 mutations were associated with longer PFS (HR 0.25, P=0.0036) in CHOP/CVP-treated patients, but not in Bendamustine-treated patients (HR 1.11, P=0.71). Interaction analysis between the chemotherapy regimen and EZH2 mutation status showed a significant interaction term of 1.49 (P=0.011) for EZH2 mutations and Bendamustine. This increased the previously favorable HR in EZH2 unmutated patients (HR 0.55 for Bendamustine vs CHOP/CVP) to an unfavorable HR of 2.42 in EZH2 mutated patients. Overall, patients with EZH2 mutant FL appeared to benefit more from CHOP/CVP, whereas patients without EZH2 mutations had longer PFS with Bendamustine-based regimens, regardless whether chemotherapy was combined with R or G (see Figure). Conclusions: Here, we validated the prognostic utility of the m7-FLIPI for patients treated with R-CHOP/CVP. However, the m7-FLIPI was not prognostic in patients treated with Bendamustine-based regimens. While EZH2 mutation status was associated with longer PFS in patients receiving CHOP/CVP regimens (with either R or G), it did not impact treatment outcome of patients treated with Bendamustine, suggesting that EZH2 mutation status is a predictive marker for differential efficacy of the chemotherapy regimen. If confirmed, the EZH2 mutation status might be a highly useful biomarker to guide the selection of the preferred upfront chemotherapy. Figure Disclosures Oestergaard: F.

Cns Relapse

Abstract Background Central nervous system (CNS) relapse of diffuse large B-cell lymphoma (DLBCL) is a devastating event occurring in approximately 5% of patients treated with standard R-CHOP (Thanarajasingam et al, ASH 2015, abs 1456). Isolated CNS relapse is associated with significant morbidity and mortality. New treatment regimens with agents that cross the blood-brain barrier (BBB) are needed. The combination of lenalidomide with R-CHOP (R2CHOP) has shown promising results in activated B-cell (ABC) type DLBCL in phase 2 studies and is currently being evaluated in randomized trials. Lenalidomide crosses the BBB and has been demonstrated to have single-agent activity in relapsed CNS lymphoma. Accordingly, the addition of lenalidomide to R-CHOP may decrease the risk of CNS relapse. Here we characterize the combined incidence of isolated CNS relapse in a population of DLBCL patients who received R2CHOP for induction therapy in two independent phase 2 studies. Methods We analyzed the incidence of isolated CNS relapse in patients with histologically-confirmed DLBCL enrolled in two R2CHOP phase 2 trials - one conducted by Mayo Clinic (MC) and the other by Italian Lymphoma Foundation (FIL) - in the context of clinical variables that included age, gender, disease stage, cell of origin, and administration of CNS prophylaxis. We assessed CNS-International Prognostic Index (CNS-IPI) factors (age, stage, lactate dehydrogenase level, ECOG performance status, extranodal sites, adrenal/kidney involvement) and classified patients into groups of low, intermediate, and high risk of CNS relapse. The risk of CNS relapse in R2CHOP-treated patients was then estimated and compared against published rates in RCHOP-treated patients based on CNS-IPI score. Results One hundred thirty-six patients with DLBCL from both cohorts (87 MC patients, 49 FIL patients) were included in this analysis. Mean age was 65 and median follow-up in 104 patients still alive was 48.2 months (range: 2.1-88.5). 61.8% of patients were male; 86.0% had stage III disease or higher; 44.1% had ECOG performance status of 0; cell of origin phenotype by immunohistochemistry according to Hans algorithm was germinal center B-cell (GCB), non-GCB (ABC), and not available in 43.4%, 36.8%, and 19.8%, respectively; 14.7% received intrathecal (IT) methotrexate for CNS prophylaxis per local practice. No patients received intravenous methotrexate. 10.3%, 71.3%, and 18.4% of patients were classified into low, intermediate, and high-risk CNS-IPI groups, respectively. Only one of 136 patients developed isolated CNS relapse, corresponding to an estimated incidence of CNS relapse of 0.007 (0.7%). Conclusions Despite a large proportion of patients with intermediate and high risk of CNS relapse treated in both phase 2 studies, induction therapy with R2CHOP in patients with DLBCL is associated with a lower-than-expected rate of isolated CNS relapse. The latter is unlikely to be explained by use of IT chemotherapy, which is considered to be marginally effective in this setting and was implemented only in a small proportion of patients. This suggests that addition of CNS-penetrating small molecules, such as lenalidomide, to R-CHOP may decrease the risk of CNS relapse.

Abstract Abstract 4591 Introduction: Clinicians and investigators appreciate the value of measuring HRQOL for monitoring CLL and the impact of treatments, and commonly use ECOG performance status (PS) and clinician-reported patient fatigue as surrogates for HRQOL in clinical practice. However, limited data exist on the relationships between PS, fatigue, and HRQOL in CLL patients (pts) undergoing treatment in clinical practices. We examined the associations between these measures and 3 psychometrically validated, patient-reported, HRQOL instruments: the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Methods: Data were collected as part of Connect CLL®, a prospective observational registry initiated in March 2010 involving US practices. Data on pt demographics and clinical characteristics were provided by clinicians. HRQOL was self-reported by pts at enrollment using the BFI, EQ-5D, and FACT-Leu. Mean BFI, EQ-5D and FACT-Leu scores were analyzed by ECOG PS and clinician-reported fatigue. Differences in HRQOL scores between sub-cohorts were assessed by ANOVA. Results: HRQOL data were reported by 604 pts enrolled from 10 academic, 148 community, and 3 government centers. Pts were predominantly male (62%) and white (90%); mean age was 70 (standard deviation 11) years. BFI data (scale: 0 [no fatigue] - 10 [worst fatigue]) indicated that on average pts report that global fatigue, fatigue severity and fatigue-related interference worsen by ECOG severity (Table 1) and are statistically associated with clinician-reported fatigue (Table 2). Mean EQ-5D overall HRQOL as measured by a Visual Analogue Scale (VAS) from 0 (worst) to 100 (best) worsens by ECOG severity and is significantly worse in pts with fatigue. Mean EQ-5D domain scores (scale: 1 [no problem], 2 [some problems], 3 [incapacity]) indicated that pain/discomfort, mobility and usual activities increase in severity as ECOG worsens and in pts with fatigue. FACT-Leu domains except social/family were statistically worse with worse ECOG PS and in pts with fatigue. Conclusions: Initial results from Connect CLL® indicate that HRQOL worsens with worsening ECOG PS, especially in physical / functioning domains, pain/discomfort, and mobility, and worsens across multiple domains among pts whose physicians reported fatigue. Future analyses should be conducted on how HRQOL, PS and fatigue may change over time with changes in CLL, and how they are influenced by therapies. These results may serve as baseline reference.

Introduction. Myelodysplastic Syndrome (MDS) is a disease of the elderly. Apart from IPSS, IPSS-R and WPSS, several indexes incorporating patient comorbidities (such as the MDS CI index- Della Porta et al Haematologica 2011, the HCT-CI index - Sorror et al Blood 2005) and performance status (the GFM index- Itzykson et al Blood 2011) have been used to predict outcome in MDS patients treated with azacytidine (AZA). We sought to investigate the effect of comorbidities on the outcome after AZA in a large group of patients from the MDS registry of the Hellenic MDS Study Group. Methods. The present study has been conducted as a retrospective observational cohort one. It included high-risk MDS and low blast count AML patients treated with AZA from 26 centers in Greece from 2007 to 2018. T-test and ANOVA were used to compare scale variables between two or more groups respectively. Univariate analysis of nominal and scale survival data was performed using Kaplan-Meier survival curves and Cox regression respectively. All variables achieving p<0.05 at univariate analysis were considered eligible for multivariate analysis; the latter was based on Cox regression method. Results. We analyzed 536 consecutive patients. Patient characteristics are depicted in Table 1. The median follow-up period was 27.5±4.8 months. 371 patients received at least four cycles of AZA and 165 patients received less than 4 cycles of AZA. Patients who received ≥4 cycles of AZA did not differ from those who received <4 cycles regarding gender, age, estimated Glomerular Filtration Rate (eGFR), cardiovascular, renal, and tumor comorbidities. Significantly higher IPSS-R and GFM scores at baseline were found in the group of patients receiving < 4 cycles of AZA compared to patients who received ≥ 4 cycles of AZA (p=0.042 and 0.05 respectively), while transfusion dependence at baseline occurred more often in patients who received ≥ 4 cycles of AZA (p=0.039). To assess the prognostic significance of risk factors on leukemia free survival (LFS) and overall survival (OS), univariate and multivariate analysis for the whole population was performed, as well as a landmark analysis for patients who were treated with at least 4 cycles of AZA. ECOG performance status and the presence of peripheral blasts were independent prognostic factors for LFS and OS for the whole cohort analysis while response to AZA and the presence of peripheral blasts were independent prognosticators for LFS and OS in the landmark analysis. In addition, prior low dose cytarabine was an independent adverse prognostic factor for LFS in the landmark analysis. As regards comorbidities, neither of MDS-CI, HCT-CI and GFM systems independently predicted LFS or OS in either analysis, but eGFR with a cut-off of 45 ml/min was a strong and independent prognosticator for LFS and OS in both the standard and the landmark analysis. Kaplan-Meier survival curves regarding LFS and OS at AZA initiation and landmark analysis after 4th cycle of AZA in relation with eGFR are shown in Figure 1. Conclusion. This is the first study to demonstrate the importance of eGFR at baseline as a prognostic marker for LFS and OS in high-risk MDS and low-blast AML patients treated with AZA. The role of comorbidities and PS needs to be further evaluated in this patient group.

Abstract Background: Multiple myeloma (MM) is primarily a disease of older adults with a median age at diagnosis of 66 years. Despite significant improvements in patient outcomes, there is a lag in survival in older transplant-ineligible patients compared to their younger counterparts. Traditionally, melphalan and prednisone-based regimens were the most widely accepted treatment options in this older, transplant-ineligible population. More recently, the FIRST trial has explored the use of lenalidomide and dexamethasone in these patients. Here, we sought to incorporate optimal novel agent-containing regimens in transplant-ineligible, older patients that balance efficacy with toxicity. Building on our prior experience with RVD in predominantly younger patients, our study evaluated a 3-drug regimen of modified RVD in the transplant-ineligible population. Methods: Modified RVD (“RVD-lite”) was administered over a 35-day cycle. Lenalidomide was given as a single daily oral dose of 15 mg days 1-21; bortezomib 1.3 mg/m2 once weekly subcutaneously on days 1, 8, 15, and 22; and dexamethasone 20 mg on days 1, 2, 8, 9, 15, 16, 22 and 23 for patients ≤75 yrs and days 1, 8, 15, 22 for patients older than 75 yrs. Intravenous bortezomib was used only in cycle 1 for the first 10 patients for pharmacokinetic analysis. Eligibility requirements included ECOG performance status ≤ 2 and acceptable hepatic, renal and hematologic function. The primary objective was to evaluate the objective response rate (ORR) of modified RVD in transplant-ineligible patients. Secondary objectives included evaluation of the safety profile of modified RVD, progression free survival, overall survival, time to response, response duration, the response rate with respect to cytogenetics, and the pharmacokinetic profile of intravenous and subcutaneous bortezomib. Exploratory analysis will determine minimal residual disease (MRD) status by genotyping and correlate with outcomes in patients who achieve a VGPR or better. Results: Forty-one eligible patients have enrolled between 4/17/13 and 7/18/14, and of those 38 received at least one dose of therapy. Median age at study entry was 73 years (range 65-91) with 22 women and 16 men. ECOG performance status of patients enrolled was 0 in 19 (46.3%), 1 in 15 (36.6%), and 2 in 6 (14.6%) patients. The ISS stage was I in 15 (36.6%), II in 9 (22.0%), and III in 10 (24.4%) patients. Treatment-related toxicities were reported for 34 subjects. Fatigue was the most commonly reported toxicity occurring in 17/34 (50.0%), and of those 16/17 were grade 1 or 2 and manageable. Peripheral neuropathy of any grade was reported in 14/34 (41.2%) of patients including Grade 1 -7 (20.6%), 2 – 6 (17.6%), and 3 – 1 (2.9%). 12/34 (35.3%) reported edema of which 11/12 (91.7%) were grade 1. Grade 3 or greater toxicities included hypophosphatemia - 11 (32.3%), Rash - 4 (11.8%), and mood changes - 2 (5.9%). Pharmacokinetic data comparing intravenous and subcutaneous dosing of bortezomib has been completed and analysis is in process. At a planned interim analysis after 4 cycles that included 33 patients, the investigator-reported ORR of PR or better was 81.8% (CR -5, VGPR – 11, PR - 11, SD 3). Three patients withdrew from the study after less than 1 cycle. Of those, one withdrew for worsening adrenal insufficiency, one for rash attributed to lenalidomide, and one for an unrelated toxicity prompting withdrawal at the Investigator’s discretion. Five additional patients have enrolled but have not completed 4 cycles. Of those, responses thus far include 1 CR, 2 PRs, 1 SD, and 1 patient who has not completed one cycle at the time of this analysis. Exploratory data on bone marrow samples on patients achieving VGPR or better have been collected and analysis for MRD is in process. Conclusions: ModifiedRVD appears to be a well-tolerated and highly effective regimen in the transplant-ineligible population. The ORR rate after up to 4 cycles suggests that this combination at the modified doses and on a weekly schedule is very active. The side effect profile proved manageable and well-tolerated in an older population despite the variance of performance statuses at study entrance. Interim analysis of 38 patients suggests that alternative dosing and schedule of RVD may both improve tolerability and enhance clinical benefit in newly diagnosed, transplant-ineligible MM patients.

Abstract Background: Multiple myeloma (MM) is primarily a disease of older adults with median age at diagnosis of 66 years. Although melphalan and prednisone-based regimens were traditionally the most accepted treatment options, recent use of lenalidomide and dexamethasone in this older, transplant-ineligible population as presented in the FIRST trial is the new standard of care in these patients (pts) (NEJM 2014). Here, we sought a regimen that incorporates optimal novel agents in transplant-ineligible, older pts that balances efficacy with toxicity. Building on our promising prior experience with RVD in predominantly younger pts (Blood 2010), our study evaluated a 3-drug regimen of modified RVD in the transplant-ineligible population. Methods: Modified RVD ("RVD-lite") was administered over a 35-day cycle. Lenalidomide 15 mg was given on days 1-21; bortezomib 1.3 mg/m2 once weekly subcutaneously (SC) on days 1, 8, 15, and 22; and dexamethasone 20 mg on days 1, 2, 8, 9, 15, 16, 22 and 23 for pts ≤75 yrs and days 1, 8, 15, 22 for pts older than 75 yrs. Intravenous (IV) bortezomib was used in cycle 1 for the first 10 pts for pharmacokinetic (PK) analysis. Eligibility requirements included ECOG performance status ≤ 2 and acceptable hepatic, renal and hematologic function. The primary objective was to evaluate the objective response rate (ORR) of modified RVD in transplant-ineligible pts. Secondary objectives included evaluation of the safety profile, progression free survival (PFS), overall survival, response rate with respect to cytogenetics, and the PK profile of IV and SC bortezomib. Exploratory analysis will determine minimal residual disease (MRD) status by deep sequencing and correlate with outcomes in patients who achieve a VGPR or better. Results: Fifty-three eligible pts have enrolled between 4/17/13 and 7/25/15, and of those, 50 received at least one dose of therapy. Median age at study entry was 72 years (range 65-91) with 29 women and 24 men. ECOG performance status of pts enrolled was 0 in 25 (47%), 1 in 20 (38%), and 2 in 8 (15 %) pts. The ISS stage was I in 21 (40%), II in 16 (30%), and III in 16 (30%) pts. Treatment-related toxicities were reported for 49 pts. Fatigue was the most commonly reported toxicity occurring in 31/49 (63%), and was mostly grade 1 or 2 and manageable (25/31). Peripheral neuropathy of any grade was reported in 21/49 (43%) pts including grade 1 (11, 22%), 2 (9, 18%), and 3 (1, 2%). Grade 3 or greater toxicities included hypophosphatemia in 15 (31%) and rash in 5 (10%) pts. PK data comparing IV and SC dosing showed no significant differences in plasma concentrations of bortezomib at 5 hours. In the SC route, high body mass index (BMI) patients tended to have low concentration at both the 5 and 30 minute measures but not at 5 hours. There was no correlation with BMI using the IV route. At the planned analysis after 4 cycles that now includes 40 pts, the investigator-reported ORR of PR or better was 90% (CR - 10, VGPR - 14, PR - 12, SD - 4). Five pts withdrew from the study after less than 4 cycles. Of those, one withdrew for worsening adrenal insufficiency, one for rash attributed to lenalidomide, one at the Investigator's discretion, and two for excessive travel distance. Five additional pts have been enrolled but have not completed 4 cycles. Of 48 evaluable patients, the median survival has not been reached. Median duration of follow-up is 17.2 months and the 1-year PFS is 95% (95% CI 0.888, 1) and 2-year PFS is 68% (95% CI 0.512, 0.908). Exploratory data on bone marrow samples on pts achieving VGPR or better have been collected and analysis for MRD is in process. Gene expression profiling was performed using MMprofiler (SkylineDx). High-risk signature will be correlated with pt outcomes. Conclusions: ModifiedRVD is a well-tolerated and highly effective regimen in the transplant-ineligible population. The ORR rate after 4 cycles suggests that this combination at modified doses and on a weekly schedule is very active. The side effect profile proved manageable and was well tolerated in an older population despite the variance of performance status at study entry. There were no significant differences in plasma concentrations of bortezomib observed between IV and SC dosing. The study is fully accrued and this analysis suggests that alternative dosing and schedule of RVD may both improve tolerability and enhance clinical benefit in newly diagnosed, transplant-ineligible MM pts.

Abstract Background: Clinical trial eligibility criteria balance identifying a specific patient population who may benefit from an intervention with restricting allowable comorbidities to maximize safety and avoid off-target drug effects. Patients may also be deemed ineligible for a trial for reasons that do not directly impact efficacy or safety. We identified and categorized reasons for ineligibility and compared outcomes of ineligible patients with eligible patients treated on SWOG Leukemia Committee protocols. Methods: Patients enrolled in SWOG Leukemia Committee phase II, II/III, or III protocols open since 2005 were analysed for eligibility status, reasons for ineligibility, Eastern Cooperative Oncology Group (ECOG) performance status, serious adverse events (SAEs), and outcomes, including complete remission (CR) status (as defined for each leukemia subgroup by international standards) and overall survival (OS), measured from time of study enrollment. Ineligible patients included in the studies' analyses were analyzed separately from patients excluded from analyses. Reasons for ineligibility are summarized descriptively, and logistic or Cox regression analyses accounting for clustering of outcomes within each study were performed. Multivariable analyses accounted for age, sex, trial design (randomized vs. single-arm), and disease-type (de novo vs. relapsed/refractory). Results: Pooled data (n=2,376) from 13 SWOG trials (S0106, S0301, S0325, S0333, S0432, S0521, S0530, S0605, S0703, S0805, S0910, S0919, S1117) open to accrual since 2005 were included in analyses (Table 1). Of these, 10 were phase II (77%), 2 (15%) were phase III, and 1 (8%) was phase II/III. Most studies (10/13, 77%) included patients with de novo disease: acute myeloid leukemia (AML, n=5), chronic myeloid leukemia (n=1), acute lymphoblastic leukemia (ALL, n=2), acute promyelocytic leukemia (APL, n= 1), and myelodysplastic syndromes (MDS) / chronic myelomonocytic leukemia (n=1). The remainder (4/13, 31%) enrolled previously treated patients: ALL (n=3), and AML (n=1). Across the 13 studies, 257 patients (11%) were deemed ineligible: 81 were excluded from analyses (77% of whom had a different disease than the one being studied or did not meet diagnostic criteria), and 176 were included in all analyses. The most common reasons for ineligibility among these 176 patients were missing documentation (106/176, 60%) and out of window laboratory values (28/176, 16%) or bone marrow biopsy (15/176, 9%). All patients ineligible due to out of window laboratory values did not meet the requirement of having a WBC ≤30,000/cmm within 1 day of registration on S0432, which studied schedules and dosing of tipifarnib in AML patients 70 years or older. The most common missing documentation factors leading to ineligibility were: specimens required for correlative studies (60/106, 57%) and enumeration of bone marrow promyelocytes (20/106, 19%) in non-APL, AML trials (Table 2).Comparing ineligible to eligible patients, ECOG performance status was similar (p=.29) as were the odds ratios for grades 4 and 5 SAEs: 0.74, 95% CI (0.50, 1.11), p=.15 and 0.72, 95% CI (0.17, 3.03), p=.66, respectively. Efficacy outcomes were also similar for ineligible and eligible patients: odds ratio for complete response (CR) = 0.77, 95% CI (0.48, 1.24), p=.28; and the hazard ratio for overall survival (OS) = 0.92, 95% CI (0.74, 1.14), p=.43 (Figure). Conclusions: The majority of patients ineligible for SWOG Leukemia / MDS studies are either missing documentation or have laboratory results outside of a protocol's timeframe. Despite this, there were no significant differences in ECOG performance status, SAEs (≥ grade 4), CR rates, or survival between ineligible and eligible patients. The findings of this study suggest that eligibility criteria and specific documentation requirements can be less restrictive, thus expanding patient enrollment and avoiding protocol deviations.

Abstract Early autologous hematopoietic stem cell transplantation (auto-HCT) is recommended for transplant-eligible patients (pts) with newly diagnosed multiple myeloma (MM). However, gastrointestinal toxicities, i.e., oral mucositis (OM), nausea and diarrhea, are the major limitation to the use of auto-HCT especially in the elderly population which constitute a significant proportion of MM pts, where the median age at diagnosis is 68 years. There is an unmet need for measures to minimize non-hematological toxicities without compromising melphalan anti-myeloma efficacy; this could lead to expansion of transplant eligibility to older pts. Amifostine, a FDA-approved cytoprotective agent to prevent OM for Head and Neck cancer, may reduce HDM-associated GI toxicity. We conducted a case-control study comparing auto-HCT with or without amifostine for MM pts. Methods pre-transplant amifostine has been incorporated to standard protocol for all MM patients underwent auto-HCT at University Hospitals Cleveland Medical Center (UH) for the last decade. One hundred and seven pts treated at UH who received amifostine, from January 2007 to July 2014, were compared to 114 matched-control pts treated at MD Anderson Cancer Center (MDACC) without use of this agent. The institutional review boards at both institutions approved the study. Amifostine 740 mg/m2 was administered as a bolus infusion at 24 hours and 15 minutes before HDM. All pts received ice chips peri-melphalan infusion. Survival outcomes were measured from the date of auto-HCT to the date of disease relapse or progression, Survival distribution was estimated using Kaplan-Meier methods. The effect of treatment on OS and PFS was estimated using a Cox model after controlling for the effects of age, gender, and number of prior therapies, time from diagnosis to transplant, Eastern Cooperative Oncology Group (ECOG) performance status and number of infused CD34+ cells. Results Pts' characteristics were similar in both groups.Median follow-up of surviving pts was 35 (range 2-100) months in both cohorts. Amifostine therapy was well tolerated without any serious adverse effects. There was no significant difference between all-grade OM, nausea or vomiting between the two cohorts. However, &gt; grade II GI toxicities were significantly lower in the amifostine group as follows: OM: 27.1% vs 47.4% (P=0.002), diarrhea: 56.1% vs. 72.7% (P=0.006), nausea: 31.8% vs. 86.0% (P=0.0001) and vomiting: 18.7% vs. 52.6%, (P=0.0001) (Figure-1) (Table-1). Median time to platelet engraftment was similar between the two groups while neutrophil engraftment period was shorter with use of amifostine (10 vs. 11 days, P=0.011) (Table-2). Multivariable logistic regression showed that use of amifostine pre-transplant was associated with a significant decrease in OM, diarrhea, nausea and vomiting. Pts who received amifostine and melphalan developed grade ≥ II OM significantly less often than those given melphalan alone with odds ratio (OR) = 0.366 (95% CI: 0.196-0.685, P=0.001; Table 3). Female gender was associated with a significant increase in OM, nausea and vomiting. Female pts were more likely to develop grade ≥ II OM with OR of 1.967 (P=0.017). Similarly, an ECOG performance status (PS) of ≥ 2 was associated with a significant increase in OM and diarrhea. For every additional score of ECOG, the risk of having grade ≥ II OM increased 1.89 fold (p=0.015). Subgroup analysis of grade II and higher OM rates are shown in Table-4. Use of amifostine was associated with reduced grade II or higher GI toxicity after adjusting for the effects of age, gender, number of prior therapies, time from diagnosis to transplant, ECOG PS and infused CD34 cell dose. There was no detrimental effect of amifostine on progression-free or overall survival. Conclusions Our analysis indicates that the use of two amifostine doses of 740 mg/m2 before auto-HCT is safe and associated with significant reduction in grade II and higher GI toxicities without any deleterious effect on engraftment or anti-myeloma efficacy. Amifostine use could conceivably allow further melphalan dose-intensification for pts with resistant or high-risk disease. Also, pre-treatment with amifostine potentially could expand the utilization of auto-HCT for modestly frail MM pts that might not be considered eligible for this treatment modality. The protective effect of amifostine should be confirmed in randomized trial.

Abstract Background: When administered subcutaneously (SC), the epigenetic modifier, azacitidine (AZA) is shown to improve overall survival in patients (pts) with AML compared with conventional care regimens (Fenaux, JCO, 2010; Dombret, Blood, 2015). CC-486, the oral formulation of AZA, is in clinical development for use in hematologic malignancies. An early dose-finding study of CC-486 administered on a 7-day schedule showed it to be safe and clinically active in pts with AML (Garcia-Manero, JCO, 2011; Gore, Blood, 2011). Extending CC-486 dosing for more than 7 days may increase AZA exposure to leukemic cells over the treatment (Tx) cycle to improve response. Objective: Evaluate the safety and efficacy of CC-486 administered in extended dosing schedules (14 days or 21 days per 28-day cycle) in pts with AML. Methods: Pts with AML from two phase I/II studies were sequentially assigned to receive CC-486 in 1 of 4 extended dosing regimens: 300mg QD x14 days (d)/28d (14-QD), 300mg QD x21d/28d (21-QD), 200mg BID x14d/28d (14-BID), or 200mg BID x21d/28d (21-BID). Hematologic responses (complete remission [CR], partial remission [PR], CR with incomplete hematologic recovery [CRi], marrow CR [mCR]), were assessed using IWG criteria for AML (Cheson, J Clin Oncol, 2003), and hematologic improvement (HI) and transfusion independence (TI) were assessed using IWG criteria for MDS (Cheson, Blood, 2006). Tx-emergent adverse events (TEAEs) were graded by NCI-CTCAE v3.1 or v4.0. Results: In all, 23 pts with AML participated in the studies: 14-QD n=4, 21-QD n=12, 14-BID n=4, 21-BID n=3. Median age was 68 years (range 44 - 93), 48% were male, 22% and 78% had ECOG performance status scores of 0-1 or 2, respectively, median % bone marrow blasts was 25%, and median baseline hematology counts were: Hgb 9.1 g/dL (7.4 - 11.7), platelets 33 x 109/L (3 - 435), and ANC 0.3 x 109/L (0 - 6.4). Median time from diagnosis was 1.1 month (range -0.2 - 82.1). Eleven pts (52%) had prior MDS and 13 pts (57%) had received prior Tx for MDS (n=5) or AML (n=8), including 5 pts (38%) who had received hypomethylating agents (HMAs). The median number of CC-486 Tx cycles for all pts was 4 (1 - 9) (Figure). Overall response (CR, PR, CRi, mCR, HI or TI) rate was 48% (11/23), with generally comparable responses and response rates across the 4 dosing regimens (Table 1). Responses were observed in 4 pts (50%) who were relapsed/refractory to prior AML Tx. Two pts (40%) who had received prior HMA Tx responded, 1 of whom attained CR. HI was achieved by 32% (7/22) of pts, and 20% (3/15) of RBC transfusion-dependent pts attained RBC TI. Six pts with prior MDS (55%) responded during Tx. One pt proceeded to transplant. Febrile neutropenia (30%) and anemia (22%) were the most common grade 3-4 TEAEs (Table 2). Incidences of grade 3-4 TEAEs were generally similar across the 4 CC-486 dosing regimens. Conclusions: CC-486 administered in extended 14- or 21-day per cycle schedules was well tolerated. One-half of these older pts with AML had a hematologic response, including pts who had prior MDS, or AML that failed or lost response to prior Tx. Interestingly, pts who previously received injectable HMA Tx had hematologic responses (including CR) with CC-486, likely due to the alternative methylation pattern obtained with prolonged oral administration (Laille, Plos One, in press). Ease of administration of CC-486 can facilitate long-term Tx for sustained disease modification, provide an additional option for failure of IV/SQ HMA therapy, and may improve outcomes in combination Tx regimens, which warrant investigation.

Abstract Background: The utility of reduced-intensity conditioning hematopoietic stem cell transplantation (RIC HSCT) for fit elderly patients with advanced myelodysplastic syndromes (MDS) is unclear. Methods: The MDS Transplant-Associated Outcomes Study, or "MDS-TAO," was a prospective longitudinal observational study at the Dana-Farber/Harvard Cancer Center designed to examine survival, quality of life, and other outcomes for RIC HSCT versus non-HSCT approaches for HSCT-eligible patients with advanced MDS ages 60 to 75. All patients who met eligibility criteria were approached in the leukemia or HSCT clinics; 96% agreed to enroll. Inclusion criteria included histologically-confirmed diagnosis of MDS or CMML, and (1) therapy-related disease or (2) Int-2/high IPSS (Greenberg, Blood, 1997), or (3) non-IPSS poor-risk cytogenetics (Haase, Blood, 2007), or (4) severe cytopenia/platelet or red cell transfusion-dependence. Exclusions were (1) comorbidities that in the judgment of the treating physician precluded HSCT eligibility (2) prior donor search and (3) patient unwillingness to consider HSCT. Considering time to transplant as a time-dependent variable, hazard ratio for ultimate HSCT was estimated using Cox regression analysis controlling for age, gender, ECOG performance status, IPSS, IPSS cytogenetic risk group, and year of consent. Landmark analyses at 5 months were conducted to present estimates of overall survival for patients who were alive for at least 5 months and received HSCT versus patients who did not (landmark cohort). Subgroup analyses (e.g., molecular characteristics) are also ongoing. Results: 290 patients were enrolled between May 2011 and May 2018; 24 had less than 1.5 months of follow up after consent and were excluded from this analysis. Of the remaining 266 patients, 143 were deceased at last follow up. Baseline characteristics are presented in the table. The median follow-up time among survivors was 31 months (range 1.9, 84). 102 patients received HSCT, of whom 45 subsequently died; of the 164 patients who have not undergone HSCT, 98 have died. The median time to HSCT among those transplanted (n=102) was 4.6 months. The median follow-up for patients alive and not yet transplanted (n=66) was 24 months (range 1.9, 82). Considering time to HSCT as a time-dependent variable (n=266), the hazard ratio for death in multivariable analysis was 0.63 (95% CI 0.42-0.96, p=0.03). Poor risk IPSS cytogenetic group was the only other factor associated with mortality, HR=1.86 (95% CI 1.15-3.00, p=0.006); age, gender, ECOG performance status, IPSS, and consent year were not. Five months was chosen for the landmark analysis given it was closest to the median time to HSCT. In the landmark cohort (N=229), HSCT patients were more likely to have Int-2/high IPSS at baseline (65% vs 35% for none, p=0.0003). No other baseline characteristics were different. Figure A shows Kaplan-Meier plots for the landmark cohort, comparing 54 who received HSCT ≤ 5 months versus 175 patients who did not receive a transplant within 5 months (log rank p=0.04). Figure B shows Kaplan-Meier plots for HSCT comparing 99 patients who received HSCT at any time during follow-up versus 130 patients who did not (log rank p=0.005). Conclusion: In this large cohort of fit elderly patients with advanced MDS, a treatment strategy that included HSCT was associated with better overall survival. Table Table.

Tp53 Mutations

Abstract Background: TP53 mutations occur in 10-20% of patients with AML, constitute high-risk disease as per ELN criteria, and confer poorer prognosis. Venetoclax combination therapies and CPX-351 were recently approved for AML treatment and lead to improved outcomes in subsets of high-risk AML, however the most effective approach for treatment of TP53-mutated (m) AML remains unclear. In this study we explored the clinical outcome of TP53m AML patients treated over the last 8 years as novel therapies have been introduced to our therapeutic armamentarium. Methods: We conducted a multicenter observational study in collaboration with 4 U.S. academic centers and analyzed clinical characteristics and outcome of 174 TP53m AML patients diagnosed between March 2013 and February 2021. Mutation analysis was performed on bone marrow specimens using 42, 49, 199, or 400 gene targeted next generation sequencing (NGS) panels. Patients with an initial diagnosis of AML were divided into 4 groups (GP) based on the progressive use of novel therapies in clinical trials and their approvals as AML induction therapy during different time periods: 2013-2017 (GP1, n= 37), 2018-2019 (GP2, n= 53), 2019-2020 (GP3, n= 48) and 2020-2021 (GP4, n= 36) to analyze difference in outcome. Results: Baseline characteristics were not significantly different across different GP, as shown in Table 1. Median age of patients was 68 (range [R], 18-83), 65 (R, 29-88), 69 (R, 37-90) and 70 (R, 51-97) years in GP1-4, respectively (p=0.40). The percentage of patients with de novo AML/secondary AML/therapy-related AML in GP1-4 was 40/40/20, 36/29/24, 37.5/37.5/25 and 28/52/20, respectively (p=0.82). The proportion of patients with complex cytogenetics (CG) was 92%, 89%, 96% and 94% in GP1-4, respectively (p=0.54). The median TP53m variant allele frequency (VAF) was 48% (range [R], 5-94), 42% (R, 5-91), 45% (R, 10-94) and 60% (R, 8-82) in GP1-4, respectively (p=0.38). Four (11%), 13 (24.5%), 10 (21%) and 9 (25%) patients had multiple TP53 mutations in GP1-4, respectively (p=0.33). The proportion of patients who received 3+7 (30%, 16%, 6% & 8%; p=0.01), HMA only (11%, 18%, 2% & 8%; p=0.06), venetoclax-based (2.5%, 12%, 48%, & 61%; p &lt;0.01) and CPX-351 induction (16%, 40%, 28% & 5%; p&lt;0.001) were varied in GP1-4, respectively. The rate of CR/CRi was 22%, 26%, 28% and 18% in GP1-4, respectively (p=0.63). Treatment related mortality during induction was observed in 3%, 7%, 10% and 17% of patients in GP1-4, respectively (p=0.18). Overall, 28 (16%) patients received allogeneic hematopoietic stem cell transplantation (alloHCT) after induction/consolidation: 22%, 15%, 17% and 11% in GP1-4, respectively (p=0.67). In subset analysis, there was no difference in the rate of CR/CRi with venetoclax-based regimens vs. others (39% vs 61%, p=0.18) or with CPX-351 vs. others (25% vs 75%, p=0.84). The median progression-free survival was 7.7, 7.0, 5.1 and 6.6 months in GP1-4, respectively (p=0.60, Fig 1A). The median overall survival (OS) was 9.4, 6.1, 4.0 and 8.0 months in GP1-4, respectively (p=0.29, Fig 1B). In univariate analysis for OS, achievement of CR/CRi (p&lt;0.001) and alloHCT in CR1 (p&lt;0.001) associated with favorable outcome, whereas complex CG (p=0.01) and primary refractory disease (p&lt;0.001) associated with poor outcome. Multiple TP53 mutations (p=0.73), concurrent ASXL1m (p=0.86), extra-medullary disease (p=0.92), ≥ 3 non-TP53m mutations (p=0.72), TP53m VAF ≥ 40% vs. &lt; 40% (p=0.25), induction with CPX-351 vs. others (p=0.59) or venetoclax-based regimen vs. others (p=0.14) did not show significance for favorable or poor OS in univariate analysis. In multivariable analysis, alloHCT in CR1 (hazard ratio [HR]=0.28, 95% CI: 0.15-0.53; p=0.001) retained an association with favorable OS and complex CG (HR 4.23, 95%CI: 1.79-10.0; p=0.001) retained an association with dismal OS. Conclusion: We present the largest experience with TP53m AML patients analyzed by NGS. Although outcomes were almost universally dismal, alloHCT appears to improve the long-term survival in a subset of these patients. Effective therapies are warranted to successfully bridge patients to alloHCT and to prolong survival for transplant ineligible patients. Figure 1 Figure 1.
