Abstract: Purpose In patients with relapsed acute myeloid leukemia (AML) 〉 60 years of age we analyzed age at relapse, interval from first complete remission (CR1) to relapse, cytogenetic risk at initial diagnosis, prior allogeneic stem cell transplantation (alloSCT) and FLT3/NPM1 mutational status as possible prognostic factors for overall survival (OS). Introduction After achieving CR1 more than 50% of elderly AML patients eventually relapse. Prognostic factors for OS are poorly defined in this patient population. For younger patients with relapsed AML a risk score has been described including age at relapse, interval from CR1 to relapse, cytogenetic risk at initial diagnosis and prior stem cell transplantation (SCT) as prognostic factors. We sought to investigate whether these are also prognostic factors in elderly patients with relapsed AML. In addition, we assessed the prognostic impact of FLT3- and NPM1 mutational status (wild-type (wt) or mutated (mut)) at diagnosis. Patients and methods In the ongoing multicenter OSHO trial #69 for AML patients 〉 60 years we evaluated data of all relapsed patients. Overall survival was calculated from the day of first relapse until the day of death using the Kaplan Meier method. Univariate analysis was performed to test for the influence of age at relapse, interval from CR1 to relapse, cytogenetic risk at initial diagnosis, prior alloSCT and FLT3/NPM1 mutational status. Subsequently, independent prognostic factors were defined in a multivariate analysis with age at relapse, time from CR1 to relapse, cytogenetic risk at initial diagnosis and prior alloSCT as covariates. Results From April 2005 until April 2013 904 patients were registered. 733 of these received intensive induction chemotherapy which resulted in CR1 in 447 (61%) pts. In this patient group 260 relapses were observed after a median interval, calculated from the day of CR1, for living patients of 2.7 years (range 0.1 to 7.5). Median age at relapse was 69 years (range 60 – 85) with 129 (49.6%) pts. being 60 to 68 years old, 102 (39.2%) pts. being 69 to 74 years old and 29 (11.1%) pts. being 75 to 85 years old. Median interval from CR1 to relapse was 0.58 years (0.07 – 6.28). 114 (43.8%) relapses occurred up to 6 months after CR1, 119 (45.8%) between 7 and 18 months after CR1 and 27 (10.4%) later than 18 months after CR1. Only five (1.9%) relapsed pts. showed good risk cytogenetics at diagnosis, whereas it was of intermediate risk in 159 (61.1%) pts., of poor risk in 68 (26.2%) pts. and unknown in 28 (10.8%) pts. Forty-one (15.8%) pts. had received prior alloSCT in CR1. Information on FLT3- and NPM1 mutational status at diagnosis was available in 194 (74.6%) pts. 110 (42.3%) pts. had FLT3/NPM1 wt/wt, 48 (18.5%) pts. had FLT3/NPM1 wt/mut, 23 (8.8%) pts. had FLT3/NPM1 mut/wt and 13 (5.0%) pts. had FLT3/NPM1 mut/mut. OS rate at 2 years of all relapsed pts. was 13 ± 2%. For patients younger than 69 years and for those 69 years of age or older OS rate at 2 years was 17 ± 4% and 9 ± 3%, respectively (p=0.03). The interval between CR1 and first relapse also affected 2 year-OS with 7 ± 3%, 15 ± 4% and 36 ± 12% for pts. with relapse up to 6 months, 7 to 18 months and later than 18 months after CR1, respectively ( 18 months: p=0.009). OS rate at 2 years was also influenced by cytogenetic risk at initial diagnosis with 17 ± 3% for pts. having good or intermediate risk cytogenetics and 3 ± 2% for those with poor risk cytogenetics (p 〈 0.0005). Prior alloSCT had a negative influence on OS. Two-year OS rate was 10 ± 5 and 13 ± 3% (p= .015) for patients with prior alloSCT vs. those without prior alloSCT, respectively. FLT3/NPM1 mutational status at diagnosis had no impact on OS. In univariate analysis age at relapse (p 〈 0.04), interval from CR1 to relapse (p 〈 0.0005), cytogenetic risk at initial diagnosis (p 〈 0.02) and prior alloSCT (p 〈 0.02) were shown to be prognostic factors for OS, whereas FLT3/NPM1 mutational status was not significant (p=0.82). In multivariate analysis the same factors remained significant but only interval from CR1 to relapse (p 〈 0.0005) and prior alloSCT (p=0.003) were independent. Conclusion In AML patients 〉 60 years in first relapse OS is poor. Longer interval from CR1 to relapse and no prior alloSCT are independent beneficial prognostic factors for OS. FLT3/NPM1 mutational status at diagnosis has no prognostic impact on OS.

Abstract: To compare progression-free survival between single and tandem high-dose chemotherapy (HDT) followed by autologous stem-cell transplantation in chemotherapy-sensitive metastatic breast cancer patients. Patients and Methods Between February 1997 and June 2001, 187 patients with complete and partial remission were randomly assigned to receive either one or two cycles of HDT, consisting of thiotepa (125 mg/m 2 /d for 4 days), cyclophosphamide (1,500 mg/m 2 /d for 4 days), and carboplatin (200 mg/m 2 /d for 4 days), followed by autologous stem-cell transplantation. Results One hundred seventy one of 187 randomly assigned patients completed first HDT, but only 52 of 85 completed the second HDT cycle in the tandem HDT arm. The rate of complete remission on an intent-to-treat-basis was 33% in the single-dose HDT arm and 37% in the tandem HDT arm (P = .48). The median progression-free survival times in single and tandem HDT arms were 9.4 and 11.2 months, respectively (one-sided P = .06; two one-sided P = .12), whereas median overall survival time tended to be greater after single versus tandem HDT (29 v 23.5 months, respectively; P = .4). In a multivariate analysis for progression-free survival, tandem HDT (hazard ratio [HR] = 0.71; 95% CI, 0.52 to 0.98; P = .03) and achievement of complete remission after induction chemotherapy (HR = 0.59; 95% CI, 0.37 to 0.96; P = .03) were factors for a better progression-free survival, whereas the factor of three or more sites of metastases (HR = 1.66; 95% CI, 1.12 to 2.47; P = .01) was associated with a worse progression-free survival. Conclusion Despite a trend of improved progression-free survival, tandem HDT cannot be recommended for patients with chemotherapy-sensitive metastatic breast cancer because of a trend for shorter overall survival and higher toxicity compared with single HDT.

Abstract: Abstract 131 Introduction. Autologous stem cell transplantation (ASCT) after cytoreductive induction is considered standard of care for younger patients (pts) with multiple myeloma (MM). The previous standard of induction, the Vincristin-Adriamycin-Dexamethasone (VAD) combination, achieves inferior results compared with induction regimens which combine the proteasome inhibitor Velcade (V = Bortezomib) with Dexamethasone (D)(=VD) and a cytostatic drug such as Doxorubicin (PAD = VD plus Doxorubicin). Velcade-based induction therapy was shown to translate into better myeloma control after high dose melphalan and to lead to prolonged progression-free survival. In order to find a more efficacious and safer drug combination for induction therapy in MM, we tested the combination of Velcade with Cyclophosphamide and Dexamethasone (VCD). Methods. This trial was designed as an open, prospective, multi-center, uncontrolled, combined phase II/III study. As previously reported (Kropff M et al., Ann Hematol 2009), in the first 30 pts the optimal dose of iv Cyclophosphamide in combination with V and D was defined as 900 mg/m2 on d1. Between 03/2006 and 03/2009 we enrolled an additional 370 pts up to 60 years of age with untreated MM to receive three 3-week cycles of induction treatment with V 1.3 mg/m2 iv d1,4,8,11; D 40 mg/d orally d1,2,4,5,8,9,11,12; and C 900mg/m2 iv d1 before scheduled high dose melphalan and ASCT. The primary endpoint of the study is response rate on day 63 after 3 cycles of VCD according to EBMT and IMWG criteria. Results. Final data from 400 pts from 39 German centers will be presented at the meeting. In the currently evaluable 300 pts (mean age 52.3 years; 1.7% stage I, 21.3% stage II, 77.0% stage III) molecular cytogenetic analysis showed a prevalence of 13q- in 38%, of t[4;14] in 13% and of 17p- in 12% of pts (no changes in 35%). All 300 pts (88.3% of whom completed three cycles) were included in the intent-to-treat analysis. Overall response rate (ORR = CR+PR) was 84%, with 10% CR and 74% PR, 5.7% MR, 7.3% NC and 2.3% PD. The negative prognostic impact of 13q- or t[4;14] was abrogated (ORR normal 87.3%, 13q- 83.7%, t[4;14] 90.0%), the unfavorable influence of p53 loss in the 17p- subgroup was still detectable (ORR 69.2%) but this did not reach statistical significance. VGPR rates will be reported at the meeting. Serious adverse events were documented in 78/300 (26.0%) patients. Death rate was remarkably low (1.3%, of which one was not related to the trial medication). 155/300 (52%) of pts experienced grade 3/4 non-serious AEs and of these leucopenia (93/300 pts= 31%), thrombocytopenia (7%), neutropenia (6%), anaemia (5%) were the most frequent events. 80 AEs grade 3 or 4 and 45 SAEs were of infectious origin and occurred in 47/300 pts. 80/130 SAEs (61.5%) were at least possibly related to Velcade. 101/300 pts (34%) developed episodes of peripheral neuropathy. PNP was grade 1 in 62/300 pt (20.7%), grade 2 in 31/300 pt (10.3%) and grade 3 in 7/300 pts (2.3%). Conclusion. This analysis demonstrates that proteasome inhibition by Velcade in combination with Dexamethasone and iv Cyclophosphamide (VCD) is an induction regimen for newly diagnosed MM which is highly effective in a short period of time, has a rather low toxicity profile and is feasible for administration in an outpatient setting. Based on these characteristics, VCD qualifies to become a new standard for MM induction therapy.

Abstract: A post hoc subgroup analysis of two phase III trials (NCT00416273, NCT00416208) was carried out to investigate the influence of 100/140 and 200 mg/m² melphalan as well as single/double autologous stem cell transplantation (ASCT) on progression‐free survival (PFS). Additionally, the effect of bortezomib consolidation on PFS was analyzed. Methods Following induction therapy and high‐dose melphalan with subsequent ASCT, patients with newly diagnosed multiple myeloma (NDMM) were randomized 1:1 to either four 35‐day cycles of bortezomib consolidation (1.6 mg/m² IV on days 1, 8, 15, 22) or observation. Results Of the 340 patients included in this analysis, 13.5% received 1 × MEL100/140, 22.9% 2 × MEL100/140, 31.2% 1 × MEL200, and 32.4% 2 × MEL200. With higher cumulative melphalan dose, PFS improved ( P  = .0085). PFS curves of patients treated with 2 × MEL100/140 and 1 × MEL200 were very similar. The superior dose effect of MEL200 over MEL100/140 was non‐existent in the bortezomib consolidation arm but pronounced in the observation arm ( P  = .0015). Similarly, double ASCT was only beneficial in patients without bortezomib consolidation ( P  = .0569). Conclusions Full dose melphalan and double transplantation seem advantageous only as long as patients are not receiving bortezomib consolidation afterwards.

Abstract: A post hoc analysis of two phase III trials was carried out to explore the influence of age and treatment factors on the effect of bortezomib consolidation on progression‐free survival (PFS) post autologous stem cell transplantation (ASCT). Methods Patients with newly diagnosed multiple myeloma were assigned to one of two trials (ClinicalTrials.gov IDs: NCT00416273, NCT00416208), which were conducted in parallel, based on age (18‐60 or 61‐75 years, respectively). Following induction and ASCT, patients were randomized 1:1 to four 35‐day cycles of bortezomib consolidation (1.6 mg/m 2 IV on days 1, 8, 15, 22) or observation only. Results Median PFS with bortezomib consolidation vs observation was 33.6 vs 29.0 months ( P  = 0.3599) in patients aged 18‐60 years (n = 202), and 33.4 vs 26.4 months ( P  = 0.0073) in patients aged 61‐75 years (n = 155), respectively. Bortezomib consolidation post‐ASCT appeared to equalize outcomes between older and younger patients who received prior treatment of differing intensity. This suggests that the effect of consolidation may be relative and may depend on the composition and intensity of induction and high‐dose therapy. Conclusion Older patients receiving less intensive prior treatment could experience a larger PFS benefit from bortezomib consolidation.

Abstract: The concept of the DSMM 2 study was to give age-adjusted high-dose treatment to elderly myeloma patients in order to balance efficacy and toxicity. The value of conventional induction chemotherapy before high-dose melphalan and autologous stem cell transplantation and the durability of unmaintaned remissions afterwards was addressed. Between September 2001 and September 2006, 434 multiple myeloma patients 60–70 years of age with 0–1 cycle of pretreatment were recruited from 45 centers. The median age was 65 years. The patients were randomized to receive 4 cycles of conventional induction chemotherapy [A1] (n=216; VAD or idarubicin/Dex in 88%) or no induction chemotherapy [A2] (n=218). Instead of induction chemotherapy, patients in [A2] received only one short course of dexamethasone 40 mg orally (days 1–4 and 8–11). Subsequently, stem cells were mobilized after combination chemotherapy with ifosfamide, epirubicin and etoposide (IEV) followed by G-CSF; stem cells could be collected in 97% of the patients. Then the patients proceeded to tandem MEL140 (melphalan 140 mg/m2) and autologous peripheral blood stem cell transplantation with a time interval between high-dose cycles of 2 months. No consolidation or maintenance treatment was scheduled. Analyses were performed in an intent-to-treat approach. 87% of patients completed the first transplant, 74% the second. Overall, the treatment was well tolerated and grade 3/4 infections and stomatitis after high-dose melphalan occurred in 37% and 9% of patients, respectively. The overall mortality (tumor and/or toxicity) during treatment was 7.1%: 4.5% during the induction phase (6.1% in [A1] versus 2.9% in [A2]), 1.5% after mobilization and 1.1% after high-dose therapy. Notably, the best response (EBMT criteria) at the end of treatment in patients randomized to [A1] (16% CR, 64% PR) or [A2] (18% CR, 69% PR) was not different. An early loss of tumor control with disease progression occurred in 6% in [A1] versus 1% in [A2]. With a median follow-up time of 20 months, there was no significant difference in the median event-free survival (EFS) (22 months in [A1] versus 20 months in [A2]) and not in the overall survival (OS) at 4 years (63% in [A1] versus 65% in [A2]). In ≥ 50% of patients, the time between last treatment and progression was 〉 16 months. The EFS of patients 60–64 years of age and 65–70 years of age was the same. In conclusion, there was no benefit of conventional induction chemotherapy with VAD- or VAD-like regimens in patients receiving tandem MEL140 with autologous transplantation. This induction treatment therefore may be avoided. Tandem-MEL140 is feasible and well tolerated in the majority of elderly patients with symptomatic myeloma. Its profound and durable anti-tumor effect was demonstrated by prolonged unmaintained remissions. The addition of new agents given as consolidation or maintenance probably will further improve treatment results.

Abstract: Background High-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is the established standard-of-care for patients with newly diagnosed multiple myeloma (NDMM) who are young and/or fit. The number of older patients receiving HDT-ASCT is increasing, although they often receive lower-intensity treatment. Novel agent-based consolidation therapy can be used to improve responses following ASCT and prolong progression-free survival (PFS). The proteasome inhibitor bortezomib, given as post-ASCT consolidation therapy, resulted in an improved PFS compared with observation alone (median 33.6 vs 27.8 months, adjusted hazard ratio [HR] 0.70, p=0.0058) in a combined analysis of two phase 3 trials (MMY3012 [DSMM XIb; NCT00416273] and MMY3013 [DSMM X; NCT00416208]; JCO 2015;33:8511). These studies enrolled 222 patients aged ≤60 years and 158 aged 〉 60 years. In this post-hoc analysis we investigated the effect of age and related treatment factors on PFS in more detail. Methods In both trials, 371 patients were randomized 1:1 following ASCT to receive four 35-day cycles of bortezomib consolidation (n=186; bortezomib 1.6 mg/m2 IV administered on days 1, 8, 15, and 22) or observation (n=185; no treatment). The primary endpoint was PFS from the start of induction chemotherapy. Response and progression were assessed at the start of each bortezomib cycle and at the end-of-treatment/observation visit (week 25), as well as during the follow-up period of 30-60 months. Patient characteristics and treatments were compared between trials; PFS following randomization was assessed separately for each study. Univariate, bivariate, and multivariate Cox regressions were conducted to evaluate the impact of treatment group, age (≤60 vs 〉 60 years), single vs tandem ASCT, melphalan conditioning dose (MEL 〈 200 vs 200 mg/m2), bortezomib exposure during induction (exposed vs naïve), post-ASCT response (partial response vs ≥very good partial response [VGPR]), and cytogenetics on PFS. Results A number of relevant factors were different between age groups (median age in ≤60 group 53 years vs 66 years in 〉 60 group), including the HDT regimen received (MEL100 7% vs 10%; MEL140 3% vs 59%; MEL200 88% vs 31%). The rate of double transplantation was similar for the younger and older cohorts (55% vs 59%), likely due to the older patients receiving age-adjusted high-dose melphalan with a lower toxicity, allowing a similar rate of double transplantation as younger patients receiving MEL200. Among the 357 patients included in these analyses, median PFS from start of induction was 33.6 vs 27.8 months with bortezomib consolidation vs observation (log-rank p=0.0243). Median PFS for bortezomib vs observation was 33.6 vs 29.0 months (HR 0.86; p=0.3599) in the younger cohort and 33.4 vs 26.4 months (HR 0.60; p=0.0073) in the older cohort. PFS for older patients who received bortezomib consolidation was very similar to PFS in younger patients (p=0.861); survival curves were superimposable despite the older patients having received less intensive pretreatment. Univariate analysis demonstrated that treatment group (bortezomib vs observation) had an effect on PFS (HR 0.75; exploratory p-value 〈 0.05), as did age ( 〉 60 vs ≤60 years; HR 1.30), melphalan dose (200 vs 〈 200 mg/m2; HR 0.74), single vs tandem ASCT (HR 1.35), and cytogenetics (high-risk vs no change; HR 2.62). On bivariate analysis of treatment group plus other covariates, the PFS benefit of bortezomib consolidation vs observation remained consistent (HR 0.71-0.76) across analyses with other covariates. On multivariate Cox regression analysis (Table), bortezomib consolidation (HR 0.72), prior bortezomib during induction (HR 0.69), ≥VGPR post-ASCT (HR 0.76), high-risk cytogenetics (HR 2.58), and single vs tandem ASCT (HR 1.54) were independent prognostic factors for PFS. Conclusions For patients with NDMM, bortezomib consolidation post-ASCT appeared to equalize the outcome for older patients who had received less intensive pretreatment than younger patients prior to randomization. A consistent PFS benefit was demonstrated with bortezomib consolidation vs observation in the context of other prognostic factors. In a multivariate analysis, the use of tandem transplantation retained independent prognostic relevance, whereas MEL200 as first HDT did not. Table. Table.

Abstract: We assessed the safety and efficacy of bortezomib, cyclophosphamide and dexamethasone ( VCD ) induction therapy in previously untreated multiple myeloma patients. A total of 414 patients received three 21‐day cycles of VCD prior to autologous stem‐cell transplantation ( ASCT ). Most common grade ≥3 adverse events were leucopenia (31·4%) and thrombocytopenia (6·8%). The overall response rate ( ORR ) by investigator‐based assessment was 85·4%. Most patients (74%) underwent successful central laboratory‐based molecular cytogenetic analysis. No clinically relevant differences in ORR post‐induction were seen between patients with or without high‐risk cytogenetic abnormalities (86·2% vs. 84·3%). Further follow‐up data are available for 113 patients receiving ASCT who were included in a prospective consolidation trial (median follow‐up, 55·5 months); median progression‐free survival ( PFS ) was 35·3 months and median overall survival ( OS ) was not reached. In patients with high‐risk versus standard‐risk cytogenetics, median PFS was 19·9 vs. 43·6 months ( P  〈   0·0001), and median OS was 54·7 months versus not reached ( P  = 0·0022). VCD is an effective and tolerable induction regimen; results suggest that VCD induces high response rates independently of cytogenetic risk status, but after long‐term follow‐up, cytogenetic high risk is associated with markedly reduced PFS and OS post‐ ASCT .

Abstract: Although invasive fungal infection (IFI), especially invasive aspergillosis (IA) is a frequent and lethal complication in severely immunocompromised hematologic patients (pts) such as allogeneic stem cell recipients, diagnosis still remains difficult and conventional diagnostic tools lack sensitivity. Examining tissue or effusion samples might help to identify the causative pathogen of the underlying infection. However, culture-based methods for IFI detection only yield results in a minority of patients. The addition of a specific polymerase chain reaction (PCR) directly in these clinical specimens might therefore improve the detection of IA. Thus the performance of an established Aspergillus-specific nested PCR in fresh tissue and effusion samples of immunocompromised pts was evaluated. Methods By means of an established Aspergillus-specific PCR protocol, we investigated 98 fresh tissue and effusion specimens from 74 immunocompromised, predominantly hematologic patients. The diagnosis of IFI was suspected due to underlying immunosuppression and radiologic abnormalities. Of these patients 23/74 (31%) had proven (n=17) or probable (n=6) IFI using the 2008 EORTC/MSG criteria. The remaining 51 (69%) pts were classified as having either possible (n=27) or having no IFI (n=24) due to lack of host criteria or missing specific radiologic features. IA was identified as the underlying IFI in 18/23 proven/probable patients. Results PCR positivity in tissue and effusion samples was observed in 16/18 proven/probable IA and 6 possible IA patients, while patients with no IA according to EORTC/MSG did not show positive PCR signals. In 5 patients with proven IFI, non-Aspergillus moulds (2 Mucorales spp. and 3 Rhizopus spp.) were found while Aspergillus PCR remained negative. Thus, Aspergillus PCR analysis for diagnosing IA yielded sensitivity/specificity values of 0.89 (95%CI 0.67-0.97) / 1.0 (95%CI 0.86-1.0) respectively, as well as a positive likelihood ratio of 〉 200 and a negative likelihood ratio of 0.1 leading to a diagnostic odds ratio of 〉 200. Conclusions In our multicenter analysis of samples from predominantly hematologic pts with suspected IFI, we observed a good diagnostic performance of the PCR assay for detection of IA directly in fresh tissue and effusion samples. Thus, PCR testing of these samples represents a sensitive and complementary tool for identification of the underlying infection: A positive tissue/effusion PCR result makes the presence of IA highly likely whereas IA is unlikely in case of a negative result, however this could indicate non-Aspergillus IFI. For the clinician, the additional PCR testing of these specimens in pts with suspected IFI improves the diagnostic armamentarium and might help in identifying the causative pathogen.
