Abstract Introduction: Chemotherapy backbones with immunomodulatory drugs have become the standard of care for the treatment of multiple myeloma (MM). Despite improved survival outcomes, thrombotic complications remain a concern especially in the older patients with co-morbidities. A meta-analysis showed that lenalidomide might be associated with lower rate of thromboembolism than thalidomide-containing regimen in patients with newly diagnosed MM with (0.7 vs. 2.6 per 100-patient-cycle) or without prophylaxis (0.8 vs. 4.1 per 100-patient-cycle) (JTH 2011;9:653). As thalidomide is still commonly used outside of the United States, it is important to understand if the thromboprophylaxis guideline is generalizable to all immunomodulatory drugs. However, no prior study has directly compared the thrombotic incidence between the two regimens while accounting for confounders. In the current propensity score weighted study, we have examined the incidence of venous (VTE) and arterial (ATE) thromboembolism and survival for older patients with newly diagnosed MM treated with lenalidomide- versus thalidomide-containing regimen. Methods: We performed a retrospective cohort study using the SEER-Medicare database and selected all patients 66 or older with newly diagnosed MM 2007 to 2013. Patients were included if they had a prescription of IMID within twelve months of diagnosis and complete enrollment for fee-for-service and prescription drug coverage. Patients were followed from the IMID index date until first VTE occurrence or death and they were censored for disenrollment from Medicare A/B/D, enrollment in health maintenance organization, or 12/31/2014. We defined VTE (including pulmonary embolism and deep vein thrombosis) and ATE (including acute stroke and myocardial infarction) using previously validated ICD-9-CM codes with positive predictive value of 75-95% (Thromb Res 2010;126:61, Am Heart J 2004;148:99, Stroke 2014;45:3219). We used inverse probability of treatment weighting (IPTW) to balance potential confounders (demographics, year of diagnosis, co-morbidities, concurrent medications) where a standardized difference (SD) of <0.1 was considered adequate balance. Weighted Kaplan-Meier curves and Cox models (HR) were used to compare overall survival. Weighted cumulative incidence curves and Fine-Gray subdistribution hazards models (SHR) were used to compare VTE and ATE incidence where death was treated as a competing risk. Variance was estimated via 200 bootstraps. Results: Among 2397 older MM patients that met the study criteria, 78% received lenalidomide (n=1863) and 22% thalidomide (n=534). There was a strong temporal trend of increasing lenalidomide use over time (Table 1). The lenalidomide group was more likely to receive bortezomib and lower dose of dexamethasone and less likely to receive anticoagulant prophylaxis. All confounders were balanced between the two treatment groups after IPTW. The 12-month incidence of VTE (10%) and ATE (5%) were similarly high in both groups (Figure 1a-b). Lenalidomide vs. thalidomide had a SHR of 1.11 (0.59-2.02) for VTE and a SHR 0.96 (0.45-1.98) for ATE. Overall survival was also not significantly different with a HR of 0.88 (0.60-1.18) for lenalidomide vs. thalidomide. Conclusion: In this propensity score weighted study of older patients with newly diagnosed MM, the cumulative incidences of VTE and ATE were similarly high in both lenalidomide- and thalidomide-treatment groups. The lack of difference in overall survival should be interpreted with caution as residual confounding such as severity of disease could influence this outcome. Our results suggest that appropriate risk stratification and vigilant thromboprophylaxis remain essential for MM patients receiving all types of immunomodulatory drugs.

Historically, high-dose therapy in combination with autologous stem cell transplants (ASCT) for multiple myeloma (MM) was reserved for younger patients. In more recent years, the use of ASCT has expanded in the older population. However, there is still limited data on the utilization and efficacy of ASCT in older patients, particularly those over the age of 75. To further evaluate this issue, we retrospectively analyzed all patients with newly diagnosed MM between the ages of 75-78, the institutional cutoff for ASCT eligibility, that were referred to the stem cell transplant unit at our institution for consultation from the years 2012-2018. Baseline characteristics, anti-myeloma treatments, and patient outcomes were abstracted through chart review. Seventy-five patients were referred to our institution. 71% were male, 29% female. 39% patients were considered ineligible for ASCT by the consulting transplant physician. Most patients were considered transplant ineligible due to comorbidities or poor performance status. Of the 46 patients eligible for ASCT, 52% underwent the procedure during their first-line therapy. The majority of those patients received reduced intensity melphalan (140 mg/m2) while 2 patients received conventional dosing (200 mg/m2). The other 22 patients eligible for ASCT declined or elected to defer the procedure and to be treated with conventional therapy. The characteristics of these three groups were similar and are detailed in Table 1. After a median follow-up of 30 months, 25% of the patients had expired. Estimated median overall survival (OS) was 71.3 months (unable to quantitate 95% CI) for all patients. Compared to transplant eligible patients, regardless of transplant receipt, those who were transplant ineligible had a 186% increase risk for death (HR 2.86; 95% CI 1.12-7.35; p = 0.029). There was also a notable trend for longer OS in those who underwent ASCT compared to those who were eligible but declined the procedure, but it was not statistically significant (HR 0.36; 95% CI 0.10-1.28; p = 0.114). At a transplant center, two-thirds of patients referred for newly diagnosed MM between the ages 75-78 were considered eligible for ASCT and one-third underwent the procedure. Outcomes were better for patients eligible for ASCT, regardless of whether they underwent the procedure. There was also a trend for better OS in patients who underwent the procedure compared to those who declined. While small sample sizes and the retrospective nature of the study limit our ability to draw conclusions, it appears that ASCT has an OS benefit among patients age 75-78.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Abstract Abstract 2685 Poster Board II-661 Background: Although standard therapies cure most adolescents and young adults with Burkitt's lymphoma/leukemia (BL), older patients (pts) have an inferior prognosis with an estimated 1-year survival of 50%. The inferior outcome is attributable to both insufficient efficacy and excess toxicity. Cyclophosphamide (Cy) has long been recognized to be arguably the most active agent in BL. Prior work at our institution showed that high-dose Cy, equivalent to transplantation doses, could be given without stem cell rescue with minimal toxicity even in older pts. Patients and Methods: A phase II trial for pts age ≥ 30, based on intensive Cy and incorporating rituximab but no anthracycline, was developed with a primary endpoint of 1-year overall survival. Entry requirements included newly diagnosed BL or atypical BL; any performance status (PS); HIV negative; and no significant cardiac dysfunction. Renal failure, even if necessitating dialysis, was permitted if it was acute. Treatment consisted of 3 cycles, with successive cycles beginning on day 15 or when ANC was ≥ 500/μL. Cycles 1 and 2 consisted of Cy 1500 mg/m2 IV day 1; vincristine 1.4 mg/m2 (2 mg cap) day 1; prednisone 100 mg days 1-5; rituximab 375 mg/m2 IV days 1 and 8; methotrexate 3 g/m2 IV day 8 with leucovorin rescue; cytarabine 100 mg intrathecally days 1, 4, and 11; and filgrastim. Cycle 3 consisted of rituximab 375 mg/m2 IV day 1; high-dose Cy (50 mg/kg IV days 2, 3, 4, and 5) with uroprotection; filgrastim; and rituximab 375 mg/m2 IV weekly for 4 weeks once ANC was ≥ 1000/μL. Eligibility for cycle 3 included ECOG PS < 4; no disease progression or uncontrolled meningeal disease; not on dialysis; and transaminases ' 5X upper limit of normal. Results: A prespecified interim analysis of the first 12 of a planned 20 evaluable pts is presented. Diagnosis was BL in 8 and atypical BL/unclassifiable high-grade lymphoma with features intermediate between BL and diffuse large B-cell lymphoma in 4. Median age was 56 (range 34 – 75), 8/12 (67%) had Ann Arbor stage III/IV disease, and all were high-risk by Magrath's criteria. PS ranged from 0 to 4. Two pts received hemodialysis on presentation. For all pts, actuarial event-free survival and overall survival (Figure) are 66% and 75%, respectively, at both 1 year and 2 years after treatment initiation. Three pts died during cycle 1: tumor lysis syndrome on day 1, neutropenic sepsis on day 8, multiorgan failure on day 46 after respiratory arrest on day 20. All of the other 9 pts completed protocol therapy: 8 (89%) achieved anatomic CR/CRu as well as a complete metabolic response by PET, and are event-free at a median of 29 months (range < 1 – 44 months) after therapy completion. The remaining pt had residual marrow disease followed by progression and is in remission 1 year after myeloablative allogeneic BMT. Adverse events in these 9 pts included 7 neutropenic fevers; 1 non-neutropenic bacteremia; and 1 self-limited episode of pericarditis with rapid atrial fibrillation. Grade 3 peripheral neuropathy was limited to 2 pts. The planned dose intensity was achievable: median time to cycle 2 was 15 days (14 – 21), and median time from start of cycle 1 to start of cycle 3 was 31 days (28 – 35). Median time to neutrophil recovery after the last dose of Cy was 16 days (10 – 21); median time to platelets ≥ 20,000/μL, without transfusion in the preceding week, was 22 days (0 – 30). Early stopping criteria for response or all-cause mortality have not been met. Conclusion: A very short regimen based on intensive Cy without anthracycline produces a high rate of durable CR's in older, poorer-risk pts with BL or atypical BL.

Abstract Background: Assessment of malignant plasma cell cycling via plasma cell labeling index (PCLI) has been a validated prognostic tool in multiple myeloma (MM) but the test requires specialized technical expertise and is not widely available. Ki67 is a well-known protein marker of cellular proliferation on immunohistochemical (IHC) staining with prognostic utility in other malignancies. In an effort to develop a simpler system to provide analogous information to PCLI, we used a novel IHC co-staining technique for CD138 and Ki67 to quantify plasma cells in active cycling. We then performed a retrospective analysis of the ratio of Ki67/CD138 (Ki67%) in newly diagnosed patients with multiple myeloma receiving 1st-line therapy to correlate with clinical outcomes. Methods: A retrospective cohort study of patients (pts) with treated symptomatic MM was performed by interrogation of the clinical database at the Weill Cornell Medical College / New York Presbyterian Hospital. For inclusion in the analysis, subjects must have started first-line treatment in the period of 2005-2010, and had available bone marrow biopsies. Double-staining with Ki67 and CD138 was performed by IHC. The Ki67% was calculated as the percent of plasma cells expressing CD138 that were also found to express Ki67. Treatment outcomes were stratified and compared based on %Ki67. Response was determined by monthly serum protein electrophoresis / immunofixation (IFX) with free light chain analysis according to International Multiple Myeloma Working Group (IMWG) guidelines. Pts who were IFX negative but had no subsequent bone marrow biopsy were classified as being in unconfirmed complete remission. Results: We identified 151 patients with newly diagnosed MM and available %Ki67 expression who received first-line therapy over the period of 2005-2010. Patient were subdivided into two groups based on %Ki67: Low: %ki67 <= 5%, n = 87; and High: %Ki67 >5, n=64, to allow for comparison of treatment response and survival analysis. Specific therapeutic agent exposure history did not differ significantly between patients. Both groups had similar depth of response rates (ORR) to front-line therapy, Table 1. Median progression-free survival for the high versus low %Ki67 groups approached statistical significance at 54 months (95% CI 30.8,67.4) versus 26.9 months (95% CI 21.6,40.2), respectively (P = 0.083). At data cut-off, there were 30 deaths in the low %Ki67 group (1-yr OS 93%, 5-yr OS 71%) and 36 deaths in the high %Ki67 group (1-yr OS 94%, 5-yr OS 62%). Median overall survival (OS) was not reached for Ki67% <= 5% (95% CI 97.3,NR) vs. 78.9 months (95% CI 55.9,93.1) for Ki67% > 5%, (P = 0.0434), Figure 1. Multivariate cox regression for factors with influence on OS showed that only high-risk cytogenetics (HR 2.05, 95% CI 1.17, 2.92, P = 0.027), ISS (HR 1.835, 95% CI 1.33, 3.60, P = 0.000), and %Ki67 group status had an independent effect on survival outcome. Low (<=5%) versus high (>5%) %Ki67 influenced overall survival with a hazard ratio of 1.76 (CI 1.07,2.92, P = 0.027). Survival after ASCT was significantly longer in the low %Ki67 group with median OS not reached (95%CI, 97.3, NR) versus 86.9 months (95% CI 43.9, NR) for high %Ki67 group (P = 0.04). Discussion: The ratio of IHC double positive Ki67 and CD138 of > 5% is an independent prognostic marker for overall survival in newly diagnosed MM undergoing 1st line therapy. The %Ki67 serves as a simpler and widely available analog to PCLI that can be presently performed in most hematopathology laboratories.

Three hundred thirty-five previously untreated patients with multiple myeloma in clinical stages II and III entered a randomized trial comparing intermittent oral melphalan and prednisone (MP) therapy (n = 171) with MP in combination with natural (leukocyte-derived) alpha- interferon (MP/IFN) (n = 164). The treatment groups were comparable with regard to major prognostic factors. The response frequency was 42% in the MP group and 68% in the MP/IFN group (P < .0001). Eighty-five percent of IgA myelomas and 71% of Bence-Jones myelomas responded to MP/IFN compared with 48% and 27%, respectively, to MP treatment (P = .001). There was no difference in the overall survival between the two treatment groups. However, the survival of 72 patients with IgA or Bence-Jones myeloma randomized to receive MP/IFN was significantly longer (median 32 months) than that of 71 patients treated with MP (median 17 months) (p < .05). No statistically significant difference in response frequency (60% v 46%) or survival was found for patients with IgG myeloma. Hematologic toxicity, WHO grades III and IV, was higher in the MP/IFN group (48%) than in the MP group (33%) (P <.05) during the induction treatment period. Flulike syndrome was observed in 68% of patients receiving MP/IFN. The results show that MP/IFN is a well-tolerated treatment regimen, superior to MP for remission induction, and it improves significantly the overall survival for patients with IgA and Bence-Jones myelomas.

Abstract Background MP0250 is a first-in-class selective tri-specific multi-DARPin® drug candidate neutralizing VEGF-Α and HGF as well as binding to human serum albumin to increase its plasma half-life. Preclinical studies have shown that MP0250 enhances sensitivity of Multiple Myeloma (MM) cells to bortezomib, inhibits tumor growth and reduces bone destruction. In this clinical phase 2 trial (NCT03136653), we are investigating the safety, tolerability and efficacy of the combination of MP0250 plus bortezomib and dexamethasone (dex) in patients (pts) with relapsed/refractory (RR) MM previously exposed to proteasome inhibitors (PI) and immunomodulatory drugs (IMiD). Aims To study the efficacy and safety of MP0250 in combination with bortezomib and dexamethasone in patients with RRMM. Trial Design This trial is recruiting adults ≥18 years of age with RRMM who have progressed after at least two prior treatment regimens including bortezomib and an IMiD. A dose-escalation phase (part 1) consisting of two cohorts will define a safe dose of the combination of MP0250 plus bortezomib + dex followed by a dose-expansion phase (part 2). Patients were enrolled to receive iv MP0250 on day 1 + subcutaneous bortezomib 1.3 mg/m² on days 1, 4, 8, 11, oral dexamethasone (dex) 20 mg on days 1-2, 4-5, 8-9, 11-12 of each 21-day cycle. Up to 40 patients will be enrolled. Patients will receive treatment until there is documented disease progression or unacceptable toxicity. Methods The primary endpoint is efficacy in terms of overall response rate (ORR) per International Myeloma Working Group criteria. Secondary endpoints include safety, immunogenicity, progression free survival (PFS) and duration of response (DOR). Exploratory endpoints include overall survival, pharmacokinetics and potential biomarkers that include MM specific markers and cytokines monitoring bone homeostasis. The safety analysis set (SAF) is defined as patients who have received at least 1 dose of the combination of MP0250 plus bortezomib + dex. Results Data cut off was 21 July 2018. 8 pts have been treated in cohort 1 and 3 pts in cohort 2. Median time from initial diagnosis to first dose was 4.8 years (range, 1-10). Median number of prior therapies was 3 (range, 2-5). All 11 pts had prior exposure to IMiDs and PIs and 4 pts were considered PI refractory. Four patients received PI immediately prior to receive MP250 in combination. The most frequent drug-related grade ≥ 3 AEs: hypertension in 3 pts, thrombocytopenia in 6 pts, proteinuria in 2 pts and transient liver enzyme elevation in 1 patient. One dose-limiting toxicity has been reported in cohort 1 (grade 3 hypertension) and two in cohort 2 (grade 3 epistaxis, grade 3 proteinuria). There were no infusion-related reactions. Best response achieved in the 8 efficacy evaluable pts in cohort 1 was VGPR in 1 and PR in 4 for an overall response rate (ORR, ≥PR) of 62.5%. In cohort 2, 1 patient achieved Minimal Response (MR), 1 patient stable disease and 1 progressive disease. Three of four patients who were coming immediately from a PI based regimen achieved a response. Pharmacokinetics data in cohort 1 show sustained exposure over multiple cycles with a mean half-life of 11 days, and no indication of ADA mediated drug clearance was observed. Data from cohort 1 patients show accumulation of MP0250-HGF complexes over multiple cycles confirming the stable binding of MP0250 to HGF suggesting that all circulating HGF is neutralized. Summary Data from cohort 1 (8 mg/Kg q3w) suggest that MP0250 can be safely combined with bortezomib and dex in patients with relapsed and refractory MM. Durable responses were seen in patients who came from PI based pretreatment suggesting that MP0250 might be capable to reverse PI resistance.

Abstract Background Rd and MPR are effective treatments in newly diagnosed multiple myeloma (NDMM) patients (pts). In this study we compared a non-alkylating containing regimen (Rd) vs alkylating-based regimens (MPR/CPR) in elderly transplant ineligible NDMM pts. Methods Patients were randomized (2:1) to receive nine 28-day cycles of MPR/CPR or Rd. 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 >75 years pts; prednisone 1.5 mg/Kg for 4 days; CPR: cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day (eod) in >75 years pts; lenalidomide 25 mg/day for 21 days; prednisone 25 mg every other day. 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 >75 years. After induction, patients were randomized to receive maintenance with lenalidomide alone (10 mg/day for 21 days) or with prednisone (25 mg eod on days 1-28), until disease progression. The primary endpoint was progression-free survival (PFS). Results Between October 2009 and October 2012, 659 pts were enrolled ( MPR/CPR:439 and Rd:220), and 641 pts were evaluable (MPR/CPR:430 and Rd:211). Patient characteristics were well balanced in the 2 groups: median age was 73 years in both groups, 38% of pts were older than 75 years, 27% had ISS stage III in both groups, 21% of patients both in the MPR/CPR and in the Rd groups had unfavorable FISH profile [t(4;14) or t (14;16) or del17p]. After induction, the response rates were similar in the 2 groups: at least PR rate was 75% versus 79% (p=0.52) and CR rate was 9% versus 7% (p=0.35), in the MPR/CPR and Rd group, respectively. No significant difference in response rate were reported between two alkylating containing regimens. After a median follow-up of 21 months, the 2-year PFS was 55% in MPR/CPR and 49% in Rd (HR=0.86, 95% CI: 0.66-1.12, p=0.26), and 2-year OS was 84% in MPR/CPR and 80% in Rd (HR= 0.93, 95% CI: 0.60-1.41, p=0.71) At least one grade ≥3 hematological adverse event was reported in 51% with MPR/CPR and 29% with Rd (p<0.001), with a significant difference between the two alkylating agents (67% MPR and 31% CPR, p<0.001). At least one grade ≥3 extra-hematologic toxicities were similar in the two groups (31% with MPR/CPR and 28% with Rd, p=0.77). with no difference between two alkylating agents (31% both in MPR and CPR group). Second primary malignancies (SPM) were reported in 5 MPR patients (1 hematologic and 4 solid) in 1 CPR patient (hematologic) and in 2 Rd patients (both solid). Conclusion In a community-based population, triplet alkylating combinations did not lead to different PFS or OS clinical benefits over doublet therapy. Updated results will be presented at the meeting.

Abstract Background: Clofarabine is a second-generation purine nucleoside analogue, which has shown synergistic activity with cytarabine. We determined the maximum tolerated dose (MTD, primary endpoint), safety and efficacy (secondary endpoints) of clofarabine in combination with cytarabine and idarubicin in newly diagnosed acute myeloid leukemia (AML) patients with high-risk for induction failure stratified in two age groups (< 60 years and ≥ 60 years). Methods: In this prospective, open-label, multicenter phase I/II study (EudraCT 2010-021719-18, CIARA trial), newly diagnosed AML patients with high risk of induction failure (NPM1 wildtype, FLT3-ITD negative), who were eligible for intensive chemotherapy, received two induction courses (cytarabine 750 mg/m2 d1-5, idarubicin 7.5 mg/m2 in patients <60 years or 6 mg/m2 in patients ≥60 years d1+3) with increasing doses of clofarabine (20-35 mg/m2 d1-5) following a 3+3 design with extension cohorts. Consolidation consisted of up to 3 courses of high-dose cytarabine or allogeneic hematopoietic cell transplantation (HCT). Results: Forty-two patients with de novo (n=32) or secondary (n=10) AML were included. Median age was 58.5 years (range 28-73, 24 patients < 60 years, 18 patients ≥ 60 years). Intermediate/adverse risk cytogenetics were found in 22 and 12 patients, respectively (karyotype missing in 8 patients). All patients received induction 1, 27 (64%) received induction 2; 4 (10%) patients died during induction courses 1 or 2. Eight patients developed a dose-limiting toxicity (6 patients with grade 3/4 non-hematologic toxicity and 3 patients with grade 4/5 hematologic toxicity) and the MTD was determined at 30 mg/m2 clofarabine for both age cohorts (younger patients: 2 of 6 patients with DLT at 35 mg/m2, no DLT at 30 mg/m2 (n=9); older patients: 4 of 6 patients with DLT at 35 mg/m2 in the extension phase, no DLT at 30 mg/m2 (n=3). The most frequent grade 3-5 non-hematologic adverse events were febrile neutropenia, sepsis, increased liver enzymes, pneumonia, decreased appetite and diarrhea occurring in 55, 24, 21, 21, 10 and 10% of patients. The median time to neutrophils ≥0.5/nl and platelets ≥50/nl after induction 1 was 25 and 24 days, respectively. Sixteen patients (38%) proceeded to allogeneic HCT in first CR and 8 (19%) received at least one course of high-dose cytarabine consolidation. Complete remission (CR) or CR with incomplete recovery (CRi) was achieved in 67%. After a median follow up of 2.2 years the 2-year overall survival (OS) was 56% and the 2-year event-free survival was 38% (median EFS 11.4 months). Compared to a matched historical control of 197 younger AML patients (SHG 0199 trial, Schlenk et al. NEJM 2008), the CR rate was 79% in the 24 younger CIARA patients compared to 66% in the control cohort (P=.18), and 2-year OS was higher for CIARA than for control patients (74% vs 49%, P=.021, Figure A). The allogeneic HCT rate in first CR (CR1) was higher in younger CIARA compared to younger control patients (58% vs 27%, P=.002). The CR rate in older CIARA patients was 50% compared to 36% in a historical control of 191 older patients, who were selected using the same genetic inclusion criteria as for CIARA patients (HD98B trial, Schlenk et al. Haematologica 2009, P=.23). Two-year OS in older patients was similar between CIARA and control patients (33% vs 17%, P=.31, Figure B). The allogeneic HCT rate in CR1 was 11% vs 2% in CIARA vs control patients (P=.029). Conclusion: Clofarabine can be safely administered at 30 mg/m2 in combination with cytarabine and idarubicin in younger and older newly diagnosed AML patients. Allogeneic HCT in CR1 was feasible in a high proportion of younger AML patients and likely contributed to the favorable outcome compared to historical control patients.

Purpose Thalidomide is effective in the treatment of newly diagnosed and relapsed/refractory multiple myeloma (MM). However, the role of thalidomide in the post-autologous stem cell transplantation (ASCT) context remains unclear. This study assessed whether the addition of thalidomide consolidation following ASCT would improve the durability of responses achieved and overall survival. Patients and Methods Between January 2002 and March 2005, 269 patients with newly diagnosed MM who achieved disease stabilization or better with conventional induction chemotherapy received a single high-dose melphalan conditioned ASCT. Post-ASCT, 129 patients were randomly assigned to receive indefinite prednisolone maintenance therapy (control group) and 114 to receive the same in addition to 12 months of thalidomide consolidation (thalidomide group). The primary study end points were progression-free survival (PFS) and overall survival (OS). The secondary end point was tolerability. Results After a median follow-up of 3 years, the postrandomization 3-year PFS rates were 42% and 23% (P < .001; hazard ratio [HR], 0.5; 95% CI, 0.35 to 0.71) and the OS rates were 86% and 75% (P = .004; HR, 0.41; 95% CI, 0.22 to 0.76) in the thalidomide and control groups, respectively. There was no difference in survival between groups 12 months after disease progression (79% v 77%; P = .237). Neurological toxicities were more common in the thalidomide arm but there were no differences between arms for thromboembolic events. Conclusion Consolidation therapy with 12 months of thalidomide combined with prednisolone prolongs survival when used after a single high-dose therapy supported ASCT in patients with newly diagnosed MM. Furthermore, thalidomide consolidation therapy did not adversely impact on survival in the subsequent salvage setting.
