Abstract Introduction: Prognosis of elderly ALL patients is generally considered to be poor. Nonetheless, data on disease characteristics, treatment and outcome of this group of patients is scarce. Methods: Between May 2003 and October 2020, 96 patients (pts) aged > 55 years with B-precursor ALL (91 pts) or T-ALL (5 pts), received first-line induction chemotherapy (84 pts) or were admitted for salvage treatment (8 pts) or allogeneic stem cell transplantation (alloSCT, 4 pts) at the University Hospital Muenster, Germany. 78 patients were diagnosed with a common-ALL (27 pts were BCR/ABL positive) and 13 patients with a pro-B-ALL. Age adapted BFM (Berlin-Frankfurt-Muenster)-like treatment regimens, according to the recommendations of the GMALL (German multicenter ALL study group) for younger (18-55 years, 25 pts) or elderly patients (> 55 years, 68 pts) were used. In general, these protocols consisted of two cycles of induction therapy followed by consolidation, reinduction and consolidation therapy blocks in the 1 st year as well as a consecutive maintenance therapy in the 2 nd year. 3 patients (3%) received no intensive treatment due to poor performance status and comorbidities. Overall survival (OS) and relapse-free survival (RFS) were analyzed using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the log-rank-test and Cox proportional hazards model for RFS and OS, respectively. Results: Median patient age at diagnosis was 66 years (range 55-89 years). 94% of all patients had an ECOG (Eastern Cooperative Oncology Group) status of 0-2 and 92% had a Charlson comorbidity index of 0-2. The median follow-up of all patients was 2.0 years (range 20 days - 16.9 years) and of surviving patients 3.7 years (range 8.8 months - 16.9 years). A complete remission (CR) after induction therapy was documented in 62 of 81 (77%) patients receiving their initial induction therapy at our center. Minimal residual disease (MRD) status was analyzed by quantitative real time PCR in 44 of these patients and 19 patients had an MRD negative CR (43%) after induction therapy. The rate of early death after intensive therapy (death within 100 days after start of treatment) was 6%. The 3 patients not treated with intensive chemotherapy died within 3 months. 27 of 93 patients finished the first year of treatment. Subsequent maintenance therapy was administered to 12 patients. The reasons for discontinuation of conventional treatment in the first and second year were relapsed disease (31 pts), alloSCT in 1 st CR (23 pts), toxicity/patients' preference (17 pts) and death in CR under conventional therapy (7 pts). 3 patients have not completed their therapy yet. OS and RFS of the entire cohort at 1 year were 73% (95% CI: 64-82%) and 57% (95% CI: 47-67%) and at 3 years 46% (95% CI: 36-56%) and 32% (95% CI: 22-42%), respectively. The cumulative incidence of relapse at 1 and 3 years was 29% (95% CI: 20-41%) and 56% (95% CI: 45-69%), respectively. OS of those patients receiving an alloSCT (23 pts in 1 st CR, 7 pts in 2 nd CR, 3 pts with active disease, median age at alloSCT 62 years) at 1 and 3 years was 82% (95% CI: 68-95%) and 49% (95% CI: 32-67%), respectively. The cumulative incidence of relapse after alloSCT at 1 and 3 years was 16% (95% CI: 7-35%) and 32% (95% CI: 18-56%), respectively. Regarding the entire patient cohort, older age (> 75 years, 15 pts) was significantly associated with an inferior OS (p < .001). BCR/ABL status, ALL phenotype (T- or B-ALL) or intensity of conventional treatment applied (protocol originally intended for patients ≤ 55 years vs > 55 years) had no significant impact on OS. In multivariate analysis, ECOG status >2 and persisting disease after 1 st consolidation therapy were risk factor associated with inferior OS (p < .05). Conclusion: Intensive treatment is feasible in selected elderly ALL patients (> 55 years). High relapse rates and impaired survival rates underline the need for novel therapeutic strategies.

Abstract Background: Activating mutations in receptor tyrosine kinases like FLT3 (FLT3mut) lead to an aberrant signal transduction thereby causing an increased proliferation of hematopoietic cells. Internal tandem duplications (FLT3-ITD) or mutations in the tyrosine kinase domain (FLT3-TKD) occur in about 25% of younger adult patients (pts) with acute myeloid leukemia (AML), with FLT3 -ITD being associated with an unfavourable outcome. FLT3mut present an excellent target for small molecule tyrosine kinase inhibitors (TKI). The multi-targeted kinase inhibitor midostaurin (PKC412) is currently under investigation as a FLT3-inhibitor in combination with intensive chemotherapy. Monitoring of the efficacy of such a targeted therapy and correlation of the results with clinical outcome will be of major importance. The plasma inhibitor activity (PIA) assay allows the visualization of the level of dephosphorylation of the target under TKI therapy. Preliminary data suggest a correlation between the grade of dephosphorylation, as a marker for the activity of the TKI, and clinical outcome. Aims: To individually measure the level of FLT3 dephosphorylation by PIA analysis in a large cohort of FLT3-ITD AML pts treated within our AMLSG16-10 trial (NCT: NCT01477606) which combines midostaurin with intensive chemotherapy, and to correlate the results with clinical outcome. Methods: Plasma samples from pts (age 18-70 years) with newly diagnosed FLT3-ITD AML were obtained at different time points for PIA analysis. All pts were enrolled on the ongoing AMLSG 16-10 trial applying intensive therapy in combination with midostaurin (50mg twice a day). For consolidation therapy, pts proceeded to allogeneic hematopoietic stem cell transplantation (alloHSCT) as first priority; pts not eligible for alloHSCT were intended to receive 3 cycles of age-adapted high-dose cytarabine (HiDAC) in combination with midostaurin from day 6 onwards. In all pts one year of maintenance therapy with midostaurin was intended. PIA analyses were performed at defined time points (day 15 of induction, each consolidation cycle, at the end of each treatment cycle, every 3 months during maintenance therapy) as previously described (Levis MJ, et al. Blood 2006; 108:3477-83). Results: So far, PIA analyses were performed in 63 pts (median age, 51.6 years; range, 20-70 years) during (n=63) and after (n=73) first and second induction cycle, during (n=40) and after (n=53) consolidation therapy with HiDAC as well as during maintenance therapy (n=82). During and after induction therapy median levels of phosphorylated FLT3 (p-FLT3) were 46.6% (4.5-100%, <20% in 7.9%) and 39.4% (0.3-100%, <20% in 20.5%), respectively. Co-medication with azoles had no impact on p-FLT3 levels. In pts with a FLT3-ITD mutant to wildtype ratio above our recently defined cut-off value of 0.5, levels of p-FLT3 <20% were associated with a complete remission (CR)-rate of 100%, whereas in those pts with p-FLT3 levels ≥20%, 4 out of 22 pts (18%) had resistant disease. In contrast, response in pts with a mutant to wildtype ratio below 0.5 was independent of the p-FLT3 level. During and at the end of consolidation cycles as well as during maintenance therapy p-FLT3 levels in pts treated with midostaurin were 52% (14.8-100%, <20% in 5%), 63% (7.6-100%, <20% in 7.4%) and 60.2% (11.5-100%, <20% in 3.7%), respectively. In pts concomitantly treated with azoles levels of p-FLT3 were lower without reaching significance. 39 of 63 pts received alloHSCT in first CR; those pts with p-FLT3 levels <20% after induction therapy had an in trend better survival, whereas no impact of phosphorylation levels was evident in pts receiving chemotherapy alone. Conclusion: In our study of FLT3-ITD AML pts treated with midostaurin in combination with intensive chemotherapy we could show that the lowest levels of p-FLT3 were reached during and after induction therapy. In pts with a FLT3-ITD mutant to wildtype ratio >0.5, levels of p-FLT3 <20% during and after induction therapy were associated with a high CR-rate. When receiving alloHSCT these pts had an in trend better survival compared to those with p-FLT3 levels >20%. An update of the data will be presented at the meeting.

First Complete Remission

Abstract The treatment of elderly patients with acute myeloid leukemia (AML) is very disappointing. Studies have established that if half of the intensivity treated patients achieve complete remission (CR), the high rate of relapse within the first year jeopardize the long term survival. No clearly effective postremission therapy had been established. Therefore we retrospective analyzed 141 elderly patients (&gt;60 yo) in first CR, to evaluate the effectiveness of postremission therapy, consolidation (3+7or 2+5) and/or maintenance (low dose AraC). All patiens received a 3+7 induction therapy. In these 141 patients DFS and OS at 4 years are respectively 14%, and 19%. According to the clinical status of the patient after induction, 20 (14%) patients did not receive therapy after induction, 30 (21%) patients received only maintenance therapy, 53 (38%) patients received only consolidation therapy, and 38 patients (27%) received both consolidation and maintenance therapy. These 4 groups were stratified according to age (&lt; &gt;70 yo) and WBC (&lt; or &gt; 30 x 109/l) (See Tables). The outcome of these patients receiving or not post induction therapy is shown in these Tables. Patients DFS at 4 years OS at 4 years Consolidation No consolidation P value consolidation No consolidation P value Outcome of patients receiving or not consolidation therapy in 4 groups stratified according to age and WBC count &lt; 70yo and WBC&lt; 30x109/l 19% 13% p=0.01 27% 13% p=0.0074 &lt;70yo and WBC&gt;30x109/l 26% 0% p=0.08 38% 0% p=0.05 &gt;70 yo and WBC &lt; 30x109/l 0% 30% p=0.001 6% 30% p=0.01 &gt;70 yo and WBC&gt; 30x109/l 2% 0% NS 4% 0% NS In patients &gt; 70 yo and WBC &lt; 30 x 109/l patients who received consolidation have a poorer prognosis than patients who did not because the mortality in first complete remission (mortality during consolidation) was high (25% versus 0% respectively, P=0.01). Patients DFS at 4 years OS at 4 years Maintenance No Maintenance p value Maintenance No Maintenance P value Outcome of patients receiving or not maintenance therapy in 4 groups stratified according to age and WBC count &lt;70yo and WBC&lt;30x109/ 17% 20% NS 22% 25% NS &lt;70 yo and WBC&gt;30x109/l 23% 14% p=0.05 32% 23% NS &gt;70 yo and WBC&lt;30x109/l 25% 5% p=0.01 25% 5% p=0.008 &gt;70 yo and WBC &gt;30x109/l 2% 0% NS 4% 0% NS In conclusion, in patients &lt; 70 yo consolidation ± maintenance therapy (for DFS in patients with &gt; 30 x109/l) improves the outcome of these patients (DFS and OS). In patients &gt; 70 yo and with WBC &lt; 30 x109/l maintenance therapy without consolidation, improves outcome. In these later patients (&gt; 70 yo and with WBC &lt; 30 x 109/l) consolidation therapy decrease outcome. In patients &gt; 70yo and with WBC &gt; 30 x 109/l, both consolidation and/or maintenance therapy does not improve outcome.

Abstract Background Frontline ASCT is the standard of care for patients with symptomatic NDMM less than 66 years of age. 3-drug combinations are the standard induction regimens prior to ASCT. Consolidation therapy after ASCT is aimed at improving disease control through deepening responses. Maintenance therapy is administered with the objective of prolonging response duration. The all-oral combination of weekly ixazomib plus lenalidomide and dexamethasone (IRd) was recently evaluated in NDMM, was generally well tolerated and appeared active (Kumar et al, Lancet Oncology 2014;13:1503-12). We analyzed the safety and efficacy of the triplet IRd combination prior to, and as consolidation after ASCT followed by ixazomib maintenance in the initial management of MM in patients younger than 66 years in a phase 2 study (NCT01936532). Methods Patients received 3 cycles of induction therapy with Ixazomib 4 mg on days 1, 8 and 15 plus Lenalidomide 25 mg on days 1 through 21 and dexamethasone 40 mg on days 1-8-15 and 22 of a 28-day cycle followed by Melphalan 200 mg/m2 and ASCT. Two months after ASCT, patients received an early consolidation with 2 cycles of IRd identical to induction therapy followed by a late consolidation phase with 6 additional cycles of IR without dexamethasone. One month after the last consolidation cycle, patients received maintenance therapy with Ixazomib single-agent 4 mg on days 1, 8 and 15 of a 28-day cycle, during 12 months. The primary end-point was the complete response (CR) rate after extended consolidation therapy. The secondary objectives were to evaluate the overall response rate (ORR) after induction, after ASCT, after consolidation and after maintenance, to evaluate the safety of induction therapy, the feasibility of extended consolidation, the feasibility of maintenance with Ixazomib, the duration of response, progression-free and overall survival. Responses (central lab, Dr Dejoie, Nantes) were assessed according to the IMWG criteria. Toxicity was evaluated according to NCI CTCAE, version 4.03. Results From 11/2014 to 04/2015, 42 patients (21 males, 21 females, median age 60 years (43-65)) with NDMM were enrolled in 10 centers from IFM. ISS was 1 in 12 cases (29%), 2 in 23 cases (54%) and 3 in 7 patients (17%), respectively. Adverse cytogenetics (17p deletion, and/or t(4;14); central lab, Dr Avet-Loiseau) was observed in 8 patients (19%). Induction with IRd was very well tolerated. Out of 120 cycles administered for 42 patients, only 13 cases of non-hematologic grade 3-4 toxicities were reported: infections (8 cases), abdominal pain (2), atrial fibrillation (1), thrombosis (1), and DRESS syndrome leading to study withdrawal (1). No renal or liver toxicity was reported. No cardiac failure and no ischemic heart disease was documented. No grade 3-4 peripheral neuropathy was described. Response rates increased at each step of the strategy. Following 3 induction cycles of IRd, the ORR was 81%, including 12% CR plus 24% very good partial response (VGPR), and 2 patients progressed (5%). Following ASCT, the VGPR rate or better was 78% including 38% CR. Following consolidation (early 2 cycles + extended 6 cycles), the VGPR rate or better was 80% including 44% CR. The feasibility of the consolidation phase with IRd (2 cycles) and IR (6 cycles) was excellent: 34 / 37 patients who started consolidation completed the 8 planned cycles (3 discontinuations: 2 patient decisions, 1 progression to plasma cell leukemia). 34/42 patients (81%) were able to receive maintenance therapy with Ixazomib following extended consolidation. Results of maintenance and of minimal residual disease evaluation will be presented during the meeting. At the cut-off date of June 30 2016, with a median follow-up of 16 months, 3 patients / 42 (7%) have progressed, 2 during induction and 1 during consolidation, and 2 (5%) died from progressive disease. Conclusions The all-oral triplet combination IRd administered as induction prior to, and as consolidation following ASCT is safe, convenient, and effective, leading to 80% VGPR and 44% CR before maintenance. Final results on response rates following maintenance and MRD data will be presented during the meeting. Updated results on PFS and OS will also be presented.

Background: Real-world data studies showed poorer outcomes in patients with acute promyelocytic leukemia (APL) than randomized controlled trials, because elderly patients were excluded in such trials. Reportedly, the main cause of death was severe bleeding due to disseminated intravascular coagulation (DIC) during induction therapy for APL. The management of DIC was therefore crucially important especially in elderly patients. This study aimed to clarify factors associated with in-hospital death in all patients, and elderly patients with DIC during induction therapy for APL. Study Design and Methods: We retrospectively identified 1,463 patients with newly diagnosed APL who received induction therapy including all-trans retinoic acid (ATRA) between July 2007 and March 2018 from a nationwide inpatient database in Japan. In-hospital death was evaluated with multivariable logistic regression models in all patients, and in ≥60 year-old patients. Anticoagulants included recombinant human soluble thrombomodulin, delteparin (low molecular weight heparin), danaparoid sodium, gabexate mesilate, and nafamostat mesilate which were administered within three days from admission. Patients who died within three days from the admission were excluded from the study to avoid immortal time bias. Results: We identified a total of 1,138 (78%) patients who developed DIC. We excluded 23 patients who died within three days from the admission. The remaining 1,115 patients were analyzed. During hospitalization, 172 (15%) patients died at a median of 13 days (interquartile range: 7-30). Compared with younger patients (20 to 39 years old), elderly patients were significantly associated with higher in-hospital mortality (60 to 79 years old: odds ratio 5.58 [95% confidence interval 3.05-10.22], 80 years or older: 13.51 [6.07-30.08]). Patients who received ATRA monotherapy had significantly higher incidence of in-hospital death (2.48 [1.54-4.01]). Delayed initiation of ATRA was significantly associated with higher mortality (1.60 [1.11-2.30]). A total of 699 patients (63%) received anticoagulant therapies, but none of these were significantly associated with lower mortality. Use of multiple anticoagulants was significantly associated with higher in-hospital mortality (2.47 [1.16-5.26]). Subgroup analyses in patients ≥60 years old were then conducted. During hospitalization, 122 of 416 (29%) patients died at a median of 13 days (interquartile range: 7-29). Both late initiation of conventional chemotherapy and no conventional chemotherapy were significantly associated with higher in-hospital mortality (1.88 [1.01-3.49], 3.25 [1.74-6.06], respectively). Use of recombinant human soluble thrombomodulin and use of multiple anticoagulants were significantly associated with higher mortality (1.91 [1.09-3.35], 2.64 [1.01-6.90], respectively). Conclusions: Elderly patients who developed DIC during induction therapy for APL were significantly associated with higher in-hospital mortality. Immediate initiation of ATRA and early initiation of conventional chemotherapy may have contributed to preferable outcomes. Disclosures Matsuda: Kyowa Kirin: Speakers Bureau.

Abstract Background: Anthracylines are one of the major classes of drugs active against acute myeloid leukemia (AML). Increased doses of daunorubicin during induction therapy for AML have been shown to improve remission rates and survival. The ALLG used idarubicin in induction therapy at a dose of 9 mg/m2 x 3 days (total dose 27 mg/m2) in combination with high-dose cytarabine and etoposide (Blood 2005, 105:481), but showed that a total idarubicin dose of 36 mg/m2 was too toxic in this context (Leukemia 2001, 15:1331). In order to further improve outcomes in adult AML by anthracycline dose escalation, we conducted a phase 3 trial comparing standard to an increased idarubicin dose during consolidation therapy. Methods: Patients achieving complete remission after 1 or 2 cycles of intensive induction therapy (idarubicin 9 mg/m2 daily x3, cytarabine 3 g/m2 twice daily on days 1,3,5 and 7, and etoposide 75 mg/m2 daily x7; ICE protocol) were randomized to receive 2 cycles of consolidation therapy with cytarabine 100 mg/m2 per day for 5 days, etoposide 75 mg/m2 for 5 days, and idarubicin 9mg/m2 daily for either 2 or 3 days (standard and intensive arms respectively). No further protocol therapy was given. The primary endpoint was leukemia-free survival from randomization to consolidation therapy (LFS) with overall survival (OS) as secondary endpoint. Results: A total of 422 patients with AML (excluding cases with CBF rearrangements or APL) aged 16 to 60 years were enrolled between 2003-10, with 345 (82%) achieving complete remission, and 293 being randomized to standard (n=146) or intensive (n=147) consolidation arms. The median age was 45 years in both arms (range 16- 60), and both groups were balanced for intermediate versus unfavorable karyotypes and for frequency of mutations involving FLT3-ITD and NPM1 genes. Of the randomized patients, 120 in the standard arm (82%) and 95 in the intensive arm (65%) received the second consolidation cycle (p<0.001). The median total dose of idarubicin received in the 2 consolidation courses was 36 mg/m2 (range 17-45), or 99% (47-125%) of the protocol dose in the standard arm, versus 53 mg/m2 (18-73), or 98% (33-136%) of the protocol dose in the intensive arm. The durations of grades 3-4 neutropenia and thrombocytopenia were significantly longer in the intensive arm, but there were no differences in grade 3 or 4 non-hematological toxicities. There were no non-relapse deaths during consolidation on the standard arm and 2 in the intensive (0% vs 1%; p =0.50). Subsequently, 41 patients in the standard arm and 37 in the intensive arm underwent elective allogeneic BMT during first remission. On intention to-treat analysis uncensored for transplant and with a median follow-up time of 5.3 years (range 0.6 - 9.9), there was improvement in LFS in the intensive arm compared with the standard arm (3 year LFS 47% (95% CI 40-56%) versus 35% (28-44%); HR 0.74 (95% CI 0.55-0.99); p=0.045) (Figure 1). The 3 year OS for the intensive arm was 61% (95% CI 54-70%) and 50% (95% CI 43-59%) for the standard arm; HR 0.75 (95% CI 0.54-1.05); p=0.092). Although adverse cytogenetics, presence of FLT3-ITD mutation, and absence of NPM1 mutation were all associated with poorer outcomes, there was no evidence of a benefit of intensive consolidation being confined to specific cytogenetic or gene mutation sub-groups. Conclusion: We conclude that in adult patients in complete remission after intensive induction chemotherapy an increased dose of idarubicin delivered during consolidation therapy results in improved LFS, without increased non-hematologic toxicity.

Abstract Between 1997 and 2001, JALSG conducted a randomized study to assess the optimal post remission therapy for adult AML in the first CR. The JALSG AML97 enrolled 809 previously untreated AML patients (pts) aged 15–64 yrs. Induction therapy consisted of cytarabine (100mg/m2 day1–7) and idarubicin (IDR 12mg/m2 day1– 3). If the patients did not achieve remission after the first induction therapy, the same therapy was given once more. Pts were categorized into good, intermediate or poor risk groups by risk factors based on the previous JALSG AML studies. All CR pts were randomized to receive either the intensified short course post remission regimen (arm A) or the conventional JALSG’s post remission regimen for AML including maintenance therapy (arm B). Arm A: 1) AraC 200mg/m2 day1–5+ Mitoxantrone (MTZ) 7mg/m2 day1–3, 2) AraC 200mg/m2 day1–5+Daunorubicin (DNR) 50mg/m2 day1–3, 3) AraC 200mg/ m2 day1–5+ Aclacinomycin (ACR) 20mg/m2 day1–5, 4) AraC 200mg/m2 day1–5+ Etoposide (ETP) 100mg/m2 day1–5 + Vincristine (VCR) 0.8mg/m2 day 8 + Vindesine (VDS) 2 mg/m2 day10. Arm B: 1) AraC 200mg/m2 day1–5 + MTZ 7mg/m2 day1–3, 2) Behenoyl AraC (BHAC) 200mg/m2 day1–7 + ETP 100mg/m2 day1–5 + DNR 50mg/m2 day1–3 + 6 mercptopurine (6MP) day1–7, 3) BHAC 200mg/m2 day1–7 + ACR 14mg/m2 day1–7, and then 6 courses maintenance therapy: 1) BHAC 170mg/m2 day1–5 + DNR 50mg/m2 day1,4+6MP day1–7, 2) BHAC 170mg/m2 day1–5 + MTZ 5mg/m2 day1–3, 3) BHAC 170mg/m2day1–5 + ETP 80mg/m2 day1,5,7 + VDS 2mg/m2 day1,8, 4) BHAC 170mg/m2 day1–5 + ACR 14mg/m2 day1–4 + 6MP day1–7, 5) BHAC 170mg/m2 day1–5 + DNR 50mg/m2 day1–4 + 6MP day1–7, 6) BHAC 170mg/m2 day1–5 + ETP 80mg/m2 day1,5,7 + VDS 2mg/m2 day1,8. Result: Of the 809 pts registered, 789 pts (median age: 45 years) were evaluable. 621 pts (78.7%) achieved CR after one or two courses of induction therapy. The 5-year OS rate of arm A was 45.6% and of arm B 53.2% (p=0.3259). The 5-year DFS rate of CR patients was 34.8% in arm A and 28.9% in arm B (p=0.4978). Among the good risk group, the 5-year OS rate of arm A was 62.1% and of arm B 70.2% (p=0.5068), and the 5-year DFS rate of arm A was 53.4% and of arm B 42.0% (p=0.3719). Among the intermediate risk group, the 5-year OS rate of arm A was 35.6% and of arm B 45.5% (p=0.4776), and the 5-year DFS rate of arm A was 26.0% and of arm B 26.1% (p=0.9653). Among the poor risk group, the 5-year OS rate of arm A was 29.7% and of arm B was 33.4% (p=0.6523), and the 5-year DFS rate of arm A was 20.4% and of arm B was 13.5% (p=0.6339). In conclusion: JALSG’s conventional post remission therapy consisting of 3 courses of consolidation and 6 courses of maintenance therapy could be replaced by a shorter duration of intensified consolidation therapy.

Abstract Abstract 1029 Poster Board I-51 Background: Elderly patients with AML have a poor outcome, with low complete response (CR) rates and durations of CR that are typically less than 1 year, highlighting the need for more effective post-remission therapy. 5-azacitidine (AZA) is a nucleoside analogue/DNA methyltransferase inhibitor approved for use in all FAB subtypes and risk categories of myelodysplastic syndromes (MDS). In higher-risk patients with MDS, including those with AML (former RAEB-T subtype), AZA improves overall survival and delays the time to leukemia transformation. We undertook a phase 2 pilot study of low-dose subcutaneous (SC) AZA in older adult patients with AML in 1st CR or CR with incomplete platelet recovery (CRp) following standard induction therapy. Methods: Study objectives included the following: 1) determine the one year disease-free survival in elderly patients with acute myeloid leukemia (AML) in first CR/ CRp treated with low-dose SC AZA as post-remission therapy. 2) determine safety and tolerability of SC AZA administered in the post-remission setting. 3) investigate the relationship between bone marrow genomic promoter methylation with 1-year disease-free survival. Eligibility included age ≥ 60 with AML in 1st CR/ CRp following 1-2 cycles of induction chemotherapy and 1-2 cycles of consolidation therapy, ECOG PS 0-2, adequate end-organ function. AZA was administered subcutaneously on 1 of 2 different dosing schedules: A) 50 mg/m2/d x 5d (d 1-5), or B) 50 mg/m2/d x 7d (d 1-5, 8-9). Cycles were repeated every 4 weeks, and up to 12 cycles. Results: As of August 2009, 16 patients have been enrolled on the study and 15 are currently evaluable. Nine patients received dosing schedule A and 6 received schedule B. Median age was 69 years (range 62-81); M/F was 13/2; baseline cytogenetic risk categories at initial diagnoses: poor (6), intermediate (8), and unknown/not done (1). Two of 15 patients had a history of antecedent MDS. Nine of 15 patients (60%) required 2 cycles of induction chemotherapy to achieve CR/CRp. The median time from achievement of CR/CRp to AZA initiation was 13.6 weeks (range 7 – 21.9 weeks). To date, the median number of AZA cycles received was 4, ;5 patients have received ≥ 6 cycles, 2 of whom have received the 12 planned cycles and another who remains on-study after 11 cycles. Median duration of CR/CRp was 54.8 weeks (95% CI: 28.1-96.4 weeks) estimated using the Kaplan-Meier method. Only 2 of 15 (13%) patients developed grade 3-4 non-hematologic adverse events (colitis, headache). Six of 15 (40%) patients developed reversible grade 3-4 neutropenia or thrombocytopenia, but only 3 required dose reduction. No patients discontinued AZA due to toxicity, and there were no deaths that occurred on-study. Criteria for early stoppage, based upon toxicity, have not been reached. Methylation array analyses are ongoing. SC AZA administered as maintenance therapy in older patients with AML in 1st CR/CRp appears feasible and safe. Extended treatment was possible in a high proportion of patients, with encouraging early signs of durable remissions. Accrual to this trial is ongoing and updated results will be presented.

Abstract Objective: HYPER-CVAD is an intensive treatment protocol of short duration, for ALL and other lymphoid neoplasms. It is consisted of 8 alternating cycles (parts A and B): in part A (cycles 1, 3, 5, 7) fractionated doses of cyclophosphamide, vincristine, doxorubicin and dexamethazone are administrated, while in part B (cycles 2, 4, 6, 8) high doses of methotrexate and aracytin. The two first cycles compose the induction therapy, while the next 6 cycles constitute the consolidation therapy, followed by two years of maintenance therapy. Protection of CNS is achieved with intradorsal injections, whereas in Ph+ ALL patients, imatinib is also administered. The aim of this study was the clinical evaluation of MRD detection in adult patients with ALL, during chemotherapy with HYPER-CVAD. Patients/Methods: During the period 1999–2008, 30 patients were hospitalized in our hospital for ALL and were treated with HYPER-CVAD therapeutic protocol. Among them, 14/30 (46,7%) were males and 16/30 (53,3%) females (median age 43,5 years, range 16–70). Median follow-up time was 12,8 months (range 0,5–100). ALL of T-origin had 8/30 patients and of B-origin, 22/30 (1 B1-EGIL/pro-B, 17 B2-EGIL/B-common, 4 B3-EGIL/pre-B). Caryotypic analysis and FISH was done in all patients (7/30 bcr/abl+). According to classical prognostic markers of ALL: 21/30 were classified as high, 4/30 as medium and 5/30 low risk, respectively. MRD presence was detected in bone marrow samples, with flow cytometric panels, at three particular treatment time-points: completion of induction therapy (T1), completion of consolidation therapy (T2) and at the end of maintenance therapy (T3). Overall survival (OS) and disease free survival (DFS) were investigated, especially in relation to the influence of MRD presence in (OS) and (DFS), respectively. For statistical analysis, Kaplan-Meier was used. Results: At treatment time-point (T1), MRD was detected in 10/28 (35,7%) patients, at time-point (T2) in 7/23 (30,4%) and at treatment-point (T3) in 9/17 (52,94%). The influence of MRD detection in (OS) was statistically significant (p&lt;0,05) at (T2) and (T3), while in (DFS) the detection of MRD presence in any of the standardized treatment time-points resulted in decreased DFS (T1/p&lt;0,05, T2 and T3/p&lt;0,001). Conclusions: Our results suggest that MRD detection during therapy of adult ALL is a negative prognostic indicator for (OS) and (DFS), the independency of which has to be confirmed after prolonged follow-up time and increased number of cases.

Imatinib Resistance

Abstract Abstract 647 Imatinib is a selective and very potent inhibitor of the BCR/ABL kinase. It induces ongoing complete cytogenetic remissions in the vast majority of chronic phase CML patients. However, BCR/ABL persistence is the rule despite ongoing imatinib therapy. This suggests that imatinib will not to cure CML and raises concerns about emerging imatinib resistance, long-term imatinib tolerability and compliance to therapy. We previously suggested that a combination of imatinib and immunotherapy by IFN may additionally control CML via induction of autologous cytotoxic T-cell (CTL) responses, such as those directed against the leukemia-associated antigen proteinase 3 (PR3). For example, induction of PR1-CTL which recognize PR3 on CML blasts was previously shown to be associated with IFN-, but not imatinib response. Indeed, we could recently demonstrate on a cohort of 20 newly diagnosed CML patients that low dose of IFN maintenance therapy alone was able to maintain or improve remissions obtained by a prior imatinib/IFN combination treatment (A. Hochhaus et al. , ASH 2007). After a median time of IFN maintenance therapy of 1.2 years 80% of the patients remained or improved molecular remission. Here we report a significantly longer follow up of these patients and translational studies to examine markers of IFN response. Twenty pts (14 m, 6 f; median age 45, range 23-74 yrs) with low (n=13), intermediate (n=6), and high risk (n=1) according to the Hasford score risk calculation have been investigated. Imatinib therapy had been administered for 2.4 yrs (0.2-4.9), combined with PEG-IFNa2a (Pegasys®, n=17) or IFN a2a (Roferon®, n=3). Maintenance therapy consisted of PEG-IFN (n=16) or IFN (n=4). Dose was adjusted according to response and tolerability and ranged between 135 μg PEG-IFN every 3 weeks to 180 μg PEG-IFN every week, or alternatively 2 to 5 * 3 Mill IU IFN/week. Imatinib was terminated due to side effects (n=5) or upon personal request of the patients after informed consent (n=15). At the time of imatinib withdrawal, two pts were in complete molecular remission (CMR) and 15 pts in major molecular remission (MMR). After a median observation time of 2.8 yrs (range 0.5-4.5), 15 pts were in MMR, 5 of them in CMR. Thus, the number of MMR patients increased from 2 at baseline to 5 after two years. Five patients relapsed within 0.4 years (range, 0.2-0.8) after imatinib discontinuation, but were rescued with imatinib, re-establishing molecular remission. Side effects to maintenance IFN were minor. We also studied putative markers of IFN response. IFN therapy was associated with an increase in the expression of PR3, and in the presence of auto-reactive PR1-CTL. PR1-CTL frequencies were prospectively assessed without prior in vitro amplification. In one of five assessable patients PR1-CTL were detected prior to imatinib withdrawal, but in four of seven assessable patients during IFN maintenance therapy. Longitudinal measurements of PR-1 CTL counts suggested an inhibition of the expansion of PR1-CTL by imatinib, implying that an optimal CTL expansion may occur preferentially in the absence of imatinib. This would explain the conversion to a CMR status in some patients only after imatinib withdrawal. Together, IFN maintenance after a prior imatinib/IFN induction therapy may be an effective alternative to permanent imatinib therapy, because it enables to safely discontinue imatinib even in those patients that have not achieved a CMR at the time of pausing imatinib. Induction of a PR1-specific CTL response by IFN may contribute to the particular efficacy of IFN after CML-debulking by imatinib. Disclosures: Burchert: Roche: Research Funding.
