The Impact

Abstract The impact of Coronavirus disease 2019 (COVID-19) on outcomes in patients with cancer remains unclear. Acute Myeloid Leukemia (AML)/high-risk myelodysplasia (MDS) are common hematological malignancies resulting in profound immunosuppression, which is exacerbated by intensive and less-intensive chemotherapy. Importantly, venetoclax based regimens have been increasingly used during the pandemic as a strategy to reduce patient hospitalization however, there is little information concerning the impact of such regimens on COVID-19 infection rates. We therefore opened a prospective clinical study (PACE), at the start of the current pandemic in April 2020 to characterize the risk of COVID-19 infection in patients with AML/MDS-EB2 receiving intensive or non-intensive treatment, including patients treated with venetoclax-based regimens. The primary aim was to determine the incidence of COVID-19 in patients with AML /MDS-EB2 including both, prior to study entry and during treatment until 4 weeks after the last cycle of treatment. Secondary aims were to: characterize the presentation of COVID-19; define the severity and type of both non-COVID-19 and COVID-19 infections; and undertake an exploratory analysis to quantify the incidence of COVID-19 infection in patients receiving (less-intensive) venetoclax based regimens. All analysis conducted to date has been descriptive. 211/230 recruited patients had full treatment histories available, of whom 116 patients received intensive chemotherapy and 95 low intensity regimens. 48 patients received a venetoclax-based regimen. The median age of the non-intensive treatment arm was 72 years; (range 19.1-86.5) and of the intensive arm was 59 years (range 16.1-76.1). There were more cases of secondary AML and relapsed disease in the non-intensive arm as compared to the intensive arm. 25/226 evaluable patients tested positive for COVID-19 as defined by positive SARS-CoV2 PCR test, 10 with a prior diagnosis at study entry and 15 tested positive during the study. The incidence of COVID-19 infection for patients with AML/MDS-EB2 was 11.1% (90%CI: 7.8%-15.1%) (Table). A lower proportion of patients (n=6/91 6.6%) undergoing non-intensive treatment suffered COVID-19 as compared to those undergoing more intensive chemotherapy regimens (n=19/116, 16.4%). Specifically, only 3/48 (6.3%) patients undergoing a venetoclax regimen were infected with SARS-CoV2. The most common presenting symptoms of COVID-19 in this study, regardless of the intensity of chemotherapy, was fever and cough with 6/25 patients asymptomatic. The risk of death at 30 days following study entry in patients who had prior COVID-19 infection or who contracted COVID-19 during this period was 13.6%, compared to 3.9% in the overall cohort without COVID-19 infection. There was a lower incidence of non-COVID-19 related infections in patients receiving venetoclax-based regimens, n=43 infections in 24 (50.0%) of patients; with 313 infections in 94 (81%) of intensively treated patients. The overall occurrence of non-COVID-19 infection in the non-intensive arm was 87 infections in 50 (54.9%) patients. Our multi-center study provides real-world estimates for the incidence and presentation of COVID-19 infection in a cohort of patients with AML/MDS-EB2, and indicates a higher risk of death at 30 days in patients with prior COVID-19 infection prior to, or during treatment. Venetoclax based, and other non-intensive, regimens, increasingly implemented during the pandemic, to minimize patient exposure and reduce usage of hospital beds, appeared to be associated with a low incidence of COVID-19. Further follow-up will be required to understand the long-term impact of this strategy. Analysis of immune responses to COVID-19 infection and vaccination is on-going.

The Impact

Abstract Background: Approximately 20–40% of pts with NDMM present with RI, which is associated with a negative impact on survival (Rajkumar, 2005). In the pivotal phase 3 FIRST trial (median follow-up 37 months [mos]), continuous Rd improved progression-free survival (PFS) vs. melphalan-prednisone-thalidomide (MPT) in elderly NDMM pts by 28% (25.5 vs. 20.7 mos; HR = 0.72; P < 0.01) (Facon, Blood 2013). Although 121 pts receiving continuous Rd are still on Tx, the interim overall survival (OS) analysis showed a 22% reduction in the risk of death in favor of continuous Rd vs. MPT (HR = 0.78; P = 0.02). The present analysis was conducted to determine the impact of RI on PFS, OS, and time to 2nd antimyeloma Tx (AMT) as clinical study outcomes. Methods: Pts were randomized to 3 Tx arms: continuous Rd until progression (n = 535); Rd for 18 cycles (72 weeks) (Rd18; n = 541); or MPT for 12 cycles (72 weeks) (n = 547). Enrolled NDMM pts were categorized according to their renal function: 24% had normal renal function (creatinine clearance [CrCl] ≥ 80 mL/min), 44% presented with mild RI (≥ 50 and < 80 mL/min), 23% had moderate RI (≥ 30 and < 50 mL/min), and 9% had severe RI (< 30 mL/min). Pts requiring dialysis were excluded. Lenalidomide starting dose was 25 mg QD for pts with normal renal function or mild RI, 10 mg QD for moderate RI, and 15 mg QOD for severe RI. Melphalan dose was reduced by 50% in pts with moderate or severe RI. The primary endpoint was PFS (continuous Rd vs. MPT); secondary endpoints were OS, overall response rate, time to response, duration of response, time to Tx failure, time to 2nd AMT, health-related quality of life, safety, and improvement in renal function from baseline. Improvement in RI was defined as shifts from baseline to most extreme post-baseline value of the calculated CrCl as a measure of renal function during the active Tx (N = 1484). Results: A PFS benefit favored continuous Rd vs. MPT irrespective of the degree of renal function (Table 1): there was a benefit in pts with normal renal function (HR = 0.72 (0.51–1.02); P = 0.06), and better in pts with mild RI (HR = 0.79 (0.62–1.00); P = 0.05) and moderate RI (HR = 0.62 (0.45–0.85); P < 0.01). A PFS benefit was also seen with continuous Rd vs. Rd18 (a secondary comparison) in pts with mild RI and moderate RI (P < 0.01 for both). An interim OS benefit with continuous Rd vs. MPT was observed in most renal subgroups. Similar results were observed between Rd18 and MPT in terms of PFS or interim OS in any of the renal subgroups. Continuous Rd, compared with Rd18 or MPT, extended time to 2nd AMT in most renal groups except severe RI (CrCl < 30mL/min) (Table 2). Improvement in RI was observed more frequently in pts treated with continuous Rd than those with Rd18 or MPT: improvement of mild RI, 48%, 43%, and 48%, respectively; of moderate RI, 67% 61%, and 62%; and of severe RI, 64%, 59%, and 56%. Overall, < 5% of pts in any Tx group experienced a worsening in renal function status during Tx (continuous Rd 2.2%; Rd18 2.8%; MPT 2.7%). The most common grade 3–4 adverse events (AEs) for these Txs were anemia, neutropenia, thrombocytopenia, deep-vein thrombosis/pulmonary embolism (DVT/PE), and peripheral sensory neuropathy (Table 3). Tx discontinuation due to AEs increased in pts with moderate and severe RI, regardless of the type of Tx (Table 3). Conclusions: PFS, OS (at interim analysis), and time to 2nd AMT outcomes generally improved continuous Rd vs. Rd18 or MPT in transplant-ineligible NDMM pts with normal renal function, and in those with mild or moderate RI. The small number of pts in the severe RI group precluded a meaningful conclusion. Continuous Rd was generally well tolerated and renal function improved in the majority of pts during Tx with continuous Rd vs. Rd18 or MPT.

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

Abstract Background: In follicular lymphoma (FL) patients treated with first-line R-CHOP, early progression of disease (POD) within 2 years after diagnosis is associated with high risk for death (hazard ratio 6.4) and a 50% 5-year overall survival (Casulo et al. JCO 2015). Whether these observations hold for patients treated without chemotherapy is unknown. The Alliance for Clinical Trials in Oncology conducted three frontline rituximab-based non-chemotherapy-containing biologic immunotherapy doublet clinical trials: R-Galiximab (Anti-CD80, CALGB 50402), R-Epratuzumab (Anti-CD22, CALGB 50701) and R-Lenalidomide (CALGB 50803). We performed a retrospective analysis of 174 patients to determine outcomes of early progressors after initial biologic, non-cytotoxic treatment and risk factors for early POD. Methods: CALGB 50402 (n=60), CALGB 50701 (n=57), and CALGB 50803 (n=57) had similar eligibility criteria: previously untreated follicular lymphoma, grade 1, 2 or 3a with stage III, IV or bulky (single mass >7 cm) stage II disease, and ECOG PS 0 to 2. Early POD was defined as progression within 24 months from study entry. Univariate and multivariate logistic regression modeling using forward selection was performed to identify predictors of early POD. Kaplan-Meier (KM) method was used to estimate 2-year and 5-year overall survival probability. Hazard ratios (HR) and 95% CI were calculated using a univariate and multivariate Cox regression model adjusting for FLIPI. Results: Twenty-seven percent (48/174) of patients had early POD. Median survival follow-up time from study entry was 5.5 years (2.1 to 10.1 years) and median time from diagnosis to enrollment was 2 months (0.2 to 115 months). Median age was 54 (range: 22-90), 49% were male and 24% had low-, 52% intermediate- and 24% high-risk FLIPI (Table 1). Early POD from study entry conferred a worse OS [HR=4.86 (95% CI 1.90-12.4), p < 0.001]. After adjusting for FLIPI, patients with early POD from study entry had a worse OS compared with patients who did not progress within 2 years [HR=4.77 (95% CI 1.70-13.4), p=0.003]. For early POD, the 2-year survival probability was 89% (76-95%) vs. 100% for non-early POD, and the 5-year survival was 76% (60-86%) vs. 99% (95-99%), respectively (Figure 1). When the 2-year early POD interval was taken from time of diagnosis, similar findings were noted (n=171, HR for OS 5.27 (95% CI 1.98-14.0), p 0.0009) [Table 2]. Univariate analysis revealed age >60 (p=0.019), male sex (p=0.002), higher FLIPI (p<0.001), hemoglobin <10 (p=0.021), number of nodal sites >4 (p=0.010), elevated LDH (p=0.004), nodal size >7 cm (p=0.002), albumin <3.5 (p=0.030) and CD10 positivity (p=0.015) were associated with early POD, while grade and bone marrow involvement were not. Histologic biomarkers PD1 and Ki67 were not associated with early POD in this analysis. A multivariate logistic regression model showed that male sex, albumin <3.5, low absolute monocyte count, interfollicular CD10 expression and high-risk FLIPI were predictors of early POD. Conclusions: Early relapse within 2 years after diagnosis in patients receiving front-line rituximab-based biologic non-cytotoxic therapy is associated with an increased risk of death. These data are similar to previous findings in patients treated with R-CHOP from the National LymphoCare study, suggesting that the adverse survival of patients with early POD may be independent of systemic treatment modality. Novel clinicopathological approaches are needed at diagnosis to identify patients who are likely to have unfavorable outcomes, and for whom biologic doublets are efficacious.

Abstract Introduction: Chronic lymphocytic leukemia (CLL) is a common leukemia which tends to occur late in life. Comorbidities are common, and the iwCLL guidelines recommend their assessment in patients (pts) enrolled on clinical trials. The Cumulative Illness Rating Scale (CIRS) is a rigorous tool designed to evaluate the burden of comorbidities, which has been employed in therapeutic studies. Our group and others demonstrated that CIRS score predicts survival in pts with CLL treated with either chemo-immunotherapy (CIT) or novel kinase inhibitors (KI; ibrutinib) (Manda et al, 2016 & Gordon et al, 2018). However, CIRS has not become part of common clinical practice, in part due to complexities in scoring. It is also unknown whether all of the 14 organ systems included in the score carry equal weight to determine prognosis. Here we report the impact of specific comorbidities from a multicenter retrospective cohort of CLL pts treated with either CIT or KI. Methods: We conducted a retrospective analysis of pts with CLL treated at five US academic medical centers between 2000 and 2017. CIRS score was calculated as in Salvi et al, 2008. Random forest (RF) was used to assess specific comorbidities' impact on overall survival (OS) and event-free survival (EFS, defined as time to new therapy, disease progression or death). We adapted two separate approaches to investigate the RF variable selection process: variable Importance (VIMP), a property related to variable misspecification, and Minimal Depth (MD), a property derived from the construction of trees within the forest. Best variables were those selected consistently as top 3 in both VIMP and MD on the 500 RF repetitions. Because hepatic and renal comorbidities were rare they were excluded. OS and EFS were assessed by Kaplan-Meier estimates and Cox proportional hazard model adjusted for performance status and age. Significance was assessed with log-rank test. Results: 398 pts were included in the final analysis. The median age was 63 years (range, 30-93). 50% of pts (n=198) had a high CIRS score (≥7). 184 pts (46%) had comorbidities assessed in relapsed setting. For all pts, the most common treatments included ibrutinib (n=145; 37%), fludarabine-containing regimens (n=104; 26%) and bendamustine (n=39; 10%). Complex karyotype was observed in 3.5% (n=14) and 10.6% (n=42) of pts had del(17p). Pts with comorbidities (CIRS ≥7) demonstrated shortened survival following therapy, with 5-year OS of 64% vs 89% (p<0.0001) and median EFS of 24 vs 49 months (p<0.0001). Pts treated with CIT had lower CIRS scores compared pts on KIs (6.5 vs 8.7, p<0.001), however there was no difference in CIRS between pts treated with high vs. low intensity CIT (e.g. FCR/BR vs chlorambucil/rituximab [n=59]; CIRS 6.8 vs 6.6, p=0.78), indicating comorbidities are not consistently taken into account when selecting therapy. Random forest variable selections identified vascular comorbidities (e.g. DVT/PE) as the most influential risk factor for OS with CIT treatment, while HEENT and cardiac comorbidities were most impactful to OS for patients treated with KI. For EFS, the most influential comorbidities were cardiac and vascular for the CIT treatment group and endocrine and HEENT for patients treated with KI. Across EFS and OS, the most frequently selected variables in CIT were cardiac, hypertension, vascular and neurologic. We constructed a simplified scoring system assigning 1 point for each category. Comparing scores of 0, 1 and 2-4 (n=100, n=82, n=60), 5-year OS was 87%, 82% and 66%, respectively (p<0.0001). In an adjusted Cox model OS decreased between risk groups (HR=1.78; 95% CI, 1.2-2.6; p=0.004). Cardiac, vascular, HEENT and endocrine were the most frequently selected in pts receiving KI. Comparing scores of 0, 1 and 2-4 (n=50, n=51, n=55), 2-year OS was 98%, 87% and 81%, respectively (p=0.034). There was a trend towards increased risk of death in the adjusted cox model (HR=1.63; 95% CI, 0.80-3.34; p=0.19). Conclusion: Comorbidities impact survival in CLL whether treated with CIT or KI. Which comorbidities are most prognostic may vary by treatment type. Vascular and cardiac comorbidities appear to be the most relevant in CLL pts treated with CIT. Meanwhile, cardiac, endocrine and HEENT had greater impact when pts were treated with KI. A simplified CIRS score is predictive of outcomes in both treatment subgroups.

Abstract Background: AML and MDS are heterogeneous myeloid neoplasias (MN) characterized by varied pathogenic mechanisms and associated with mixed clinical outcome. Five-year overall survival rates for younger AML patients (pts) are between 40-50% and for elderly pts, a dismal 10%. Until recently, molecular information has informed risk stratification for MN patients, but targeted therapies were limited (i.e ckit, flt3 inhibitors). Clinical characterization of IDH1/2mutant MN is of particular interest since the recent availability of specific IDH1/2inhibitors (i.e., enasidenib and ivosidenib). Datasets describing the outcome for patients with MN harboring IDH1/2mutations are critical to inform the potential utility of these novel IDH inhibitors as single agents or in combination with standard of care. Ongoing clinical trials are investigating the addition of IDH inhibition for upfront AML therapy. In this retrospective study, we combined cohorts from three institutions to enable reporting of the largest cohort (N=425) of IDH mutated MN pts in order to establish a baseline for therapeutic outcomes in an era which pre-dates the availability/addition of IDH inhibitors. Methods:We identified 425 patients from three large academic centers with a confirmed diagnosis of IDH1/2mutant AML (n=387), MDS (n=29) or MPN (n=9). Blood and bone marrow samples were analyzed for the presence of recurrent somatic mutations using NGS based multi-gene targeted sequencing panels. Demographic and disease related variables were annotated for initial treatment, response to therapy (IWG criteria) and subsequent survival details (overall survival, progression free survival). Time to first relapse and duration of remission was collected for 107 patients to date. Comprehensive response assessment details were available for 234 patients. Results: Of the 425 patients, 165 had a mutation inIDH1and 264 had a mutation in IDH2(82% IDH2R140, 18% R172K). Four cases had co-occurring mutations in IDH1 & IDH2. IDH1mutant cases were younger than IDH2mutant cases (62 vs. 65 years, p=0.05), predominantly male (50% vs.38%, p=0.01) and more likely to have intermediate risk AML (68% of IDH1/IDH2mutant cases had normal karyotype). A majority of these patients were treated with cytarabine-based intensive chemotherapy (n=362). Hypomethylating agents (n=29) or other less intensive therapies (n= 27) were also used. The overall response rate (ORR) to initial therapy was 65%. Response rates were similar for patients with both IDH1and IDH2mutation (i.e, 66% to any therapy). Response to intensive chemotherapy was 68% and 64% in IDH1and IDH2mutant cases respectively. As expected IDH1/2 mutant younger pts (<60 years) had a higher response rate to intensive chemotherapy (81% and 80 % respectively). The ORR for HMA therapy was 73% (64% IDH1, 80% IDH2mutants). 34% of IDH1mutants and 30%IDH2mutant patients underwent allogeneic stem cell transplantation. We have analyzed the impact of co-occurring somatic mutations on response to intensive chemotherapy. Non-responders to intensive therapy were enriched for RUNX1(26% vs.7%, p=0.002), SRSF2(34% vs.19%, p=0.045), and ASXL1 (18% vs.9%, p=0.11) mutations and were less likely to have NPM1 (24% vs. 51%, p=0.001) mutation. The median overall survival for IDH1 and IDH2 mutant MN caseswas 16.6 and 19.1 months, respectively. Conclusions: IDH1/2 mutated young AML patients appear to have chemo-sensitive disease. Despite excellent initial responses to intensive and non-intensive chemotherapy, the overall survival for IDH mutated pts was poor with shorter than expected remissions. Co-occurring mutations in RUNX1 and SRSF2 appeared to confer therapeutic resistance. Ongoing combination and maintenance strategies with targeted IDH1/2 inhibitors in conjunction with traditional therapies offer the potential to improve upon these outcomes in IDH1/2mutant MN. Future studies exploring the impact of early transplantation on overall survival for IDH1/2mutated MN are needed Disclosures Thota: Incyte: Speakers Bureau.

Abstract Introduction : Rd and MPR showed to be effective combinations in elderly newly diagnosed multiple myeloma (NDMM) patients (pts). Cyclophosphamide is a less toxic alkylating alternative agent. EMN01 is the first trial to formally compare these three different Lenalidomide-based combinations. Maintenance with Lenalidomide has been recently approved in patients eligible for autologous stem cell transplant (ASCT). Few data are available about the best combination as maintenance in patients not eligible for ASCT. Methods : 662 pts with NDMM were randomized to receive 9 28-day cycles of Rd (lenalidomide 25 mg/day for 21 days; dexamethasone 40 mg on days 1,8,15 and 22 in pts 65-75 years old and 20 mg in those &gt;75 years), MPR (lenalidomide 10 mg/day for 21 days; melphalan orally 0.18 mg/Kg for 4 days in pts 65-75 years old and 0.13 mg/Kg in &gt;75 years pts; prednisone 1.5 mg/Kg for 4 days) or CPR (lenalidomide 25 mg/day for 21 days; cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day in &gt;75 years pts; prednisone 25 mg every other day). After induction, pts were randomized to receive maintenance with lenalidomide alone (R; 10 mg/day for 21 days) or with prednisone (RP; R, 10 mg/day for 21 days and P, 25 mg every other day), until disease progression. Results : Pts characteristics were well balanced in all groups; 217 pts in Rd, 217 in MPR and 220 in CPR arms could be evaluated. After a median follow-up of 63.7 months, median PFS was 23.2 months in MPR, 18.9 months in CPR and 18.6 months in Rd (MPR vs CPR p=0.02; MPR vs Rd p=0.08). Median overall survival (OS) was 79.9 months in MPR, 69.4 months in CPR and 68.1 months in Rd (MPR vs CPR p=0.98; MPR vs Rd p=0.64). The most common grade ≥3 adverse event (AEs) was neutropenia: 64% in MPR, 29% in CPR and 25% in Rd pts (p&lt;0.0001). Grade ≥3 non hematologic AEs were similar among arms. At the end of induction, 402 pts were eligible for maintenance, 198 in the RP and 204 in the R groups. PFS from start of maintenance was 22.2 months in the RP group and 17.6 in the R group, with 20% reduced the risk of death/progression for pts receiving RP maintenance (HR 0.81, p=0.07; Figure 1). A subgroup analysis was performed to determine the consistency of RP vs R treatment effect in different subgroups using interaction terms between treatment and cytogenetic abnormalities, ISS, age, sex, induction treatment and response before maintenance (Figure 1). No difference in OS was observed (HR 1.02, p=0.93) but the OS analysis was limited by the low number of events. Median duration of maintenance was 23.0 months in RP pts and 20.5 months in R pts, 14% and 13% of pts discontinued due to AEs, in RP and R groups, respectively. Conclusion : This phase III trial compared 2 different Lenalidomide-containing induction regimens and 2 different Lenalidomide-containing maintenance regimens in an elderly community-based NDMM population. MPR prolonged PFS by approximately 5 months, yet the higher incidence of hematologic toxicity should be carefully considered. The addition of low-dose prednisone to standard lenalidomide maintenance reduced the risk of death/progression by 20%, with a good safety profile. Updated results will be presented at the meeting.

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

The Impact

Abstract Abstract 2606 Poster Board II-582 Background: Secondary chromosomal aberrations at diagnosis occur frequently in both pediatric and adult patients with Ph+ ALL. Several studies have shown that the presence of additional cytogenetic abnormalities is a major negative prognostic factor among children and adults with Ph+ ALL. A Japanese study in adults with Ph+ ALL indicated that the adverse prognostic significance of secondary rearrangements was seen even in patients treated with imatinib-combined chemotherapy including consolidation with blood and marrow transplantation (BMT) (Haematologica 92:287, 2008). Two-year EFS in that study was 48.5±5.7%, and the 50 patients with secondary chromosomal abnormalities had a 35% - 40% lower EFS than those with t(9;22) only (p=0.003). COG AALL0031 treated children with imatinib in combination with intensive chemotherapy. This study had an overall 3 year EFS of 80±11% for those receiving chemotherapy only, an outcome similar to those receiving allogeneic BMT. We evaluated the impact of secondary chromosomal abnormalities in children and adolescents receiving this regimen. Methods: Children and adolescents (age 1–21 years) with Ph+ ALL enrolled on AALL0031 after completing 3- or 4-drug induction therapy. Imatinib was given at 340mg/m2/day for an increasing number of days in combination with an intense chemotherapy backbone. Cohort 4 received imatinib for 126 (N=12) and cohort 5 for 280 continuous days (N=50) prior to maintenance therapy. The first two cycles of the intensive chemotherapy included ifosfamide and etoposide (cycle 1) and high dose (HD) methotrexate and HD cytarabine (cycle 2). Patients were non-randomly assigned to an HLA-identical related donor BMT, if a donor was available, or to an intensive chemotherapy regimen that continued for approximately 2.2 years. Unrelated donor BMT was not allowed; these patients were taken off protocol but included in survival evaluation by an intent-to-treat evaluation. Results: Satisfactory cytogenetic results were available for 71 (76%) of 93 enrolled children. Secondary aberrations were present in 46 (65%) patients. The most frequent secondary aberrations were +der(22) (N=21), =50 chromosomes (N=14), −7/del(7p) (N=11), abnormal (9p) (N=7), and +8 (N=5). The overall 3 year CCR was 79±6% for patients in cohorts 4/5, including those with non evaluable cytogenetics (N=55). When outcome analyses were limited to Ph+ ALL patients in cohorts 4/5 (N=43), three-year CCR for patients with Ph+ alone (N=14) was 86±10% versus 71±9% for those with Ph+ and secondary abnormalities (N=29) (p=0.19). Conclusions: In this study, the lower 3 year CCR seen in patients with Ph+ ALL with secondary chromosomal abnormalities was not significantly different than for children with Ph+ alone possibly reflecting small patient numbers. The lower 3 year CCR for Ph+ ALL with secondary chromosomal abnormalities in those treated on AALL0031 (∼15% lower) appeared to be less than that seen in the previous adult trial (∼35%). This may be the result of the addition of imatinib to intensified chemotherapy reducing the poor prognostic significance of additional chromosome abnormalities seen in previous studies. Larger patient numbers and longer follow-up will be necessary to answer this question.

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

Abstract Abstract 1381 Alemtuzumab is an anti-CD52 antibody originally approved for intravenous administration three times per week to CLL patients refractory to fludarabine and previously exposed to alkylators. Since that time subcutaneous administration three times per week has become widespread because of its reduced infusional toxicity and recently demonstrated equivalent efficacy. In this study we assessed the tolerability, efficacy and pharmacokinetics of administering alemtuzumab subcutaneously weekly at up to 90 mg per dose following an initial 3+3 dose escalation (see table); we further added weekly rituximab in hopes of enhancing activity in lymph nodes. Treatment was administered in up to two eight week blocks with response evaluation between; the second 8 week block continued the dose and schedule used in weeks 5–8. No more than 45 mg was given per subcutaneous injection site. 28 patients were enrolled on this study between 7/2006 and 1/2010. The median age was 62 (range 47–76), and 75% were male. The median time from diagnosis to starting study therapy was 94 mos (14-236 mos). A majority of patients (82%) had Rai stage 3–4 disease and the median number of prior therapies was 4 (1-11). 20/28 patients (71%) had high risk deletions of 17p or 11q. 13/16 (81%) had unmutated IGVH, and 14/19 (74%) were positive for ZAP70. Early study withdrawals occurred due to pre-existing and persistent thrombocytopenia requiring study therapy to be held (n=2), persistent fever attributed to alemtuzumab (n=1), PML in retrospect present prior to study entry (n=1), and a DLT (grade 3 rituximab reaction) which was observed on dose level 2 prior to dose escalation of alemtuzumab. Overall, therapy was well tolerated; injection site reactions were minimal, primarily grade 1 (n=11) with only two grade 2 events. Other toxicities were as expected with alemtuzumab in this patient population, including grade 3–4 neutropenia (54%), grade 3–4 thrombocytopenia (57%), and single cases each of grade 3 rash, AIHA, pulmonary embolism, MRSA bacteremia, diverticular abscess, pulmonary Cryptococcus, EBV lymphoma and metastatic colon cancer. The ORR by NCI-WG criteria at wk 8 was 61% (95% CI 42–76%), with CR rate 11% (95% CI 4–27%). Two of 14 patients who completed a second eight week cycle improved their response (one PR from SD, and one CR from PR). A planned endpoint of this study was to compare lymph node staging by CT to PE, and we found that using CT scans to evaluate nodal response at 8 weeks decreased the ORR rate to 14% (95% CI 6–31%), with no CRs. Bone marrow was completely cleared of disease by 8 weeks in 8 patients and by 16 weeks in an additional 4 patients. The median PFS for the entire population was 13 months with a median follow-up of 9 months in patients who have not progressed. 10 patients have died, 5 of disease, 3 of second malignancies, 1 of PML and 1 of SCT complications. The median OS from study entry is 47 months, with 10 patients having undergone subsequent SCT. Following initiation of therapy we observed a >1,700X decrease in the median CD19+5+ cell count in peripheral blood by the start of week 3. Similar rapid depletion of all T and NK cell subsets was also observed, with first signs of recovery at week 28, and more definite recovery at week 40. Preliminary pharmacokinetic data demonstrated lower maximum levels of rituximab (p=0.06) and alemtuzumab (p=0.05) in patients with >80% bone marrow replacement by CLL but not in those with bulky lymphadenopathy. A trend toward higher alemtuzumab levels was observed in those patients with complete bone marrow clearance (p=0.1) but not in those with objective response. In conclusion, we found that administration of alemtuzumab at 90 mg subcutaneously weekly in combination with rituximab was well-tolerated, convenient and resulted in sustained adequate blood levels of both drugs in most patients. Response rates were high although in this relapsed refractory CLL population, abdominal lymphadenopathy was common, resulting in a decreased response rate when CT scans were included in staging.
