Abstract Background Initial results of the Spanish GEM2005mas65 phase III trial comparing VMP versus VTP as induction therapy in elderly patients with newly diagnosed MM did not show any difference in terms of OS or PFS. The purpose of this study was to update clinical results with a longer follow-up. Secondary objectives were to know the patterns of symptomatic relapse and response to therapy in patients previously exposed to novel agents. Methods GEM2005mas65 trial lasted from March, 2006, and October, 2008. Overall, 260 patients with untreated MM, 65 years and older, from 63 Spanish centres, were randomly assigned to receive six cycles of VMP (n=130) or VTP (n=130) as induction therapy followed by maintenance therapy with bortezomib plus prednisone (n=87) or bortezomib plus thalidomide (n=91). Results With a median follow-up of 53.2 months, median OS of the entire cohort of patients was 42.45 months. Median OS was 62 months in patients receiving VMP versus 42.6 months in patients receiving induction with VTP (P = 0.045) (Figure 1). No differences were observed in PFS, being 31 and 24.4 months in the VMP and VTP groups, respectively. At the time of the study, 167 patients had relapsed or progressed and 92 of them received some kind of post relapse treatment. Front-line therapy and clinical and biological characteristics at the time of relapse in this subgroup of patients are summarized in Table 1. Initial induction treatment consisted of VMP in 40 (43.4%) patients and VTP in 52 (56.5%) patients. Overall, after induction and maintenance therapy 66 (71.7%) patients had been exposed to bortezomib and thalidomide and 26 (28.2%) patients received bortezomib-based therapy without immunomodulatory agents before relapse. At symptomatic relapse, median age was 74 years (range 65-87) and 43 (46.7%) were male. Serum creatine level > 2 mg/dL was present in 11.9% of the patients and 4.3 % had hypercalcemia. Extramedullary disease and plasma cell leukemia was present in 17% and 4.4% of patients, respectively. Finally, severe bone disease was observed in 39 the patients. Management of relapse was very heterogeneous. Subsequent drugs used in first clinical relapse included lenalidamide combinations in 40 (43.4%) patients, bortezomib-based therapy in 19 (20.5%) patients, different chemotherapy combinations in 25 (27.1%) patients and bendamustine-prednisone in 2 (2.1%) patients. Six (6.5%) patients received only supportive at time of first relapse. Overall, 45 (52%) patients achieved partial response or better after rescue therapy. Response rates were higher after lenalidomide-based therapy (62.5%) when compared with bortezomib (42.1%) and conventional chemotherapy-based regimens (40.7%),although this difference did not translate into significant PFS advantage. After a median follow-up of 16.4 months (range 0-50.2) from clinical relapse,58 (63%) patients had died. Median PFS and OS were 10 (CI95%; 10.7-50.2) and 15.6 months (CI95%; 8.5-16.5%), respectively. In patients initially treated with VMP (n = 40) and VTP (n =52) median survival from start of subsequent therapy was 15.6 and 15.4 months, respectively. Among characteristics at relapse, only ISS stage had an impact on survival (P= 0.03).There was no difference in OS or PFS from front-line induction and/or maintenance therapies or salvage therapy. Conclusions This updated analysis of the GEM2005mas65trial shows a survival advantage of the VMP arm when compared with patients receiving VTP. Patterns of relapse were similar regardless previous induction and maintenance therapy. Finally, and when analyzing the subgroup of patients receiving active therapy at relapse, only ISS stage seemed to have a prognostic impact on OS.

Abstract Abstract 1550 Background: Clofarabine is a second generation nucleoside analogue with activity in adults with AML. A recent randomized phase III study in AML relapse showed higher response rates and better event-free survival with the combination of clofarabine and cytarabine (CA) compared to cytarabine alone. We have also reported the feasibility and safety of the addition of idarubicin to CA (CIA) in a previous phase I and II study. To explore this combination further, we conducted a phase II study of CIA in pts</= 60 years with previously untreated AML. Patients and Methods: Patients (Pts) were eligible if they were </=60 yrs of age with newly diagnosed AML. Pts were excluded for ECOG PS > 2, cardiac ejection fraction < 45%, or active and uncontrolled infection. For the first 30 pts, induction therapy consisted of Clofarabine 22.5 mg/m2 iv daily (days 1–5), Idarubicin 6 mg/m2 daily (days 1–3), and Cytarabine 0.75 g/m2 daily (days 1–5). From pt 31 onward, induction doses were amended to Clofarabine 20 mg/m2 × 5, Idarubicin 10 mg/m2 × 3, and Cytarabine 1 g/m2 × 5. Pts who have not achieved a complete remission following the induction could receive one re-induction course. Pts in CR or CRp continued with up to 6 consolidation cycles with Clofarabine 22.5 mg/m2 × 3, Idarubicin 6 mg/m2 (days 1–2), and Cytarabine 0.75 g/m2 × 3, subsequently amended to Clofarabine 15 mg/m2 × 3, Idarubicin 8 mg/m2 × 2, and Cytarabine 0.75 g/m2 × 3. Supportive care was standard. Pts ≥ 50 yrs were admitted to a laminar air flow room for the duration of the induction. Results: From April 2010 until August 2011, 51 pts have been accrued with a median age of 49 yrs (range 19–59): 33 pts (65%) with de novo AML and 18 pts (35%) with secondary AML (18 related to MDS, 7 related to therapy). Three pts (5%) had a PS of 2. Median WBC at diagnosis was 3.4 × 109/L (0.6-92.3). Thirty-three (65%) pts had abnormal cytogenetics (21/33[64%] poor risk and 5/33 [15%] intermediate risk). Molecular profile: 6 pts (11%) had FLT3/ITD, 3 pts (6%) CEBPA, and 8 pts (16%) NPM1 mutations. Thirty-five pts (69%) achieved CR and 1 (2%) CRp for an overall response rate (ORR) of 71%. 61% pts (31/51) achieved CR following one induction cycle. 18% (9/51) pts required a re-induction and 44% (4/9) of them responded after the re-induction. Responding pts received a median of 2 courses (1–8) courses. With a median follow-up of 23 weeks (3–36+) median remission duration has not been reached with a 1-yr remission probability of 85%. Ten pts (19%) died on study including 2 (4%) who died < 28 days from treatment start (one from septic shock and multi-organ failure, and one from Steven Johnson syndrome). Median overall survival (OS) for responding pts has not been reached (2–36 weeks). One-yr survival probability is 65%. Sixteen pts (31%) proceeded with an allogenic stem cell transplant in CR1. Most toxicities were </= grade 2 and included rash (41 %), nausea (29%), diarrhea (23%), elevated transaminases (21%), and elevated bilirubin (17%). Toxicities > grade 2 included elevated bilirubin (4%), hypokalemia (4%), cellulitis (4%) and seizure (1%). Myelosuppression was ubiquitous but prolonged myelosuppression > 42 days was infrequent. 76 % (39/51) pts had neutropenic fever. Conclusion: Clofarabine, Idarubicin and Cytarabine achieve a response rate of 71% in patients </=60 yrs with previously untreated AML. Induction mortality was low and the toxicity profile was expected and manageable. Longer follow up and comparisons with standard induction therapy will be needed to further assess the role of this combination in AML therapy.

3515 Background: The primary analysis of DREAM demonstrated that a maintenance therapy (MT) with bevacizumab (Bev) + EGFR TKI erlotinib (E) significantly improved progression-free survival (PFS) after a 1st-line Bev-based induction therapy (IT) in patients (pts) with unresectable mCRC. Methods: Pts were randomized to MT after an IT with FOLFOX-bev or XELOX-bev or FOLFIRI-bev between Bev alone (Bev 7.5 mg/kg q3w; arm A) or Bev+E (Bev 7.5 mg/kg q3w, E 150 mg/d ; arm B) until PD or unacceptable toxicity. Primary endpoint was PFS on MT. Secondary endpoints included PFS from inclusion, overall survival (OS) and safety. The impact of KRAS tumor status on treatment efficacy was evaluated in an exploratory analysis. Results: 700 pts were registered and 452 pts were randomized (228 in arm A, 224 in arm B). KRAS status was available for 413/452 (91%) pts. The median duration of MT was 3.6 m. Results for MT are presented below (Table). In the registered population, median OS was 24.9m (22.5 – 27.3). Conclusions: Maintenance treatment with bev + erlotinib increases PFS over maintenance with bev alone in pts with mCRC but does not prolong OS. Further follow-up will determine the impact of 2nd or 3rd line anti-EGFR Mabs in this study. Contrasting with anti-EGFR Mabs, KRAS tumor status is not mandatory to select pts with mCRC for treatment with erlotinib. Clinical trial information: NCT00265824. [Table: see text]

Abstract Background The value of Allo-SCT in myeloma is heavily disputed. In our previous Donor versus No Donor (DvND) comparison we found no survival benefit of Allo-RIC in newly diagnosed myeloma. (Lokhorst et al:Blood 2012119: 6219-6225). However, a recent update of the EBMT-NMA 2000 trial (Gahrton el al:Blood 2013121: 5055-506) suggested that extended follow-up (> 5 years) may be necessary for a correct interpretation of a potential survival benefit for Allo-RIC. Here we present the extended follow-up of our trial, in which the median follow-up of patients now exceeds over 7.5 years since the first autologous SCT. Methods Patients with an HLA–identical sibling donor included in the phase III HOVON-50 study, that was designed to assess the role of thalidomide in induction treatment and maintenance after high-dose therapy (HDM 200 mg/m2), could proceed to the Hovon 54 study in which an Allo-SCT was performed after conditioning with low dose TBI only, between 2-6 months after HDM. Among the 536 eligible patients randomized in the HOVON-50 trial, ultimately 260 patients were eligible to be included into the DvND analysis: 122 patients with a donor, of whom 99 patients received an Allo-RIC and 138 without a donor, of whom 115 patients started maintenance therapy with thalidomide. Groups were comparable with regard to age, myeloma stage, and prognostic factors including cytogenetics and ISS stage. Results 93% of the patients in the no donor group achieved at least a PR (38% CR, 71% at least VGPR ), versus 96% of the patients in the donor group (43% CR, 73% at least VGPR). After a median follow-up of 91 months after HDM, PFS and OS were comparable between the two groups. In the intention to treat analysis median PFS was 29 months for the no donor group and 30 months the no donor group (P=0.25). Median OS was 76 for the donor group and 81 months for the no donor group (P=0.61). For the patients who actually received their allocated treatment (Allo-RIC or maintenance), PFS curves started to diverge after 3 years, however no statistical difference was observed (P=0.07). Allo-RIC improved the median overall survival from 73 to 94 months compared to patients receiving maintenance. However, due to frequent late mortality (> after 96 months) in the Allo-RIC group the benefit was not statistically significant (P=0.54). No subgroup including those achieving CR or those with high risk features (ISS, deletion of chromosome 13) did benefit from Allo-RIC. Conclusion This analysis failed to show improvement of tandem Auto Allo-RIC as part of first line therapy in myeloma as compared to Auto-SCT followed by maintenance therapy, even after extended follow-up.

Abstract Background Lenalidomide is an effective treatment for myeloma and has been studied in a range of combination regimens worldwide. The results of these studies have suggested that prolonged exposure to lenalidomide is important to improve outcomes both as a maintenance agent post-transplant (Attal M et al NEJM 2012, McCarthy et al NEJM 2012) and in the transplant ineligible population (Palumbo A et al NEJM 2012, Benboubker L et al NEJM 2014). In the Myeloma XI study, the largest of its kind, we explored the use of oral lenalidomide continued to disease progression compared to no therapy in both newly diagnosed transplant eligible (TE) and transplant non-eligible (TNE) populations. Here we present the results of this maintenance randomization, which demonstrate the efficacy and safety of maintenance lenalidomide. Methods The Myeloma XI study is a Phase III, UK-based, multicenter, open-label, parallel group, randomized controlled trial for newly diagnosed symptomatic myeloma patients of all ages and includes a maintenance comparison of lenalidomide versus no maintenance. Newly diagnosed symptomatic myeloma patients both TE and TNE were enrolled to the study. Induction treatment in both pathways was with thalidomide or lenalidomide plus cyclophosphamide and dexamethasone, with appropriate dose reductions for TNE patients. TE patients proceded to a standard melphalan 200mg/m2 transplant. Patients were randomized to either maintenance lenalidomide or observation after achieving maximum response (TNE) or at 100 days after transplant (TE). Lenalidomide was administered at a dose of 10mg daily in 21/28 day cycles until disease progression. Dose adjustments for renal impairment and following AEs were permitted. The primary endpoints for the maintenance randomization were progression-free (PFS) and overall survival. Secondary endpoints included response, toxicity and PFS2. Time-to-event endpoints were measured from maintenance randomization. This abstract summarizes a preliminary analysis, final data will be presented at the meeting. The median follow up in this analysis is 26 months [IQR 12-41]. Results A total of 1550 patients, 828 TE and 722 TNE, median age 61 and 74 years, respectively, were randomized between lenalidomide (n=857) and no maintenance (n=693). The arms were well-balanced for clinical features and response to induction therapy (e.g. ISS stage III: 27% vs 23%, VGPR/CR: 73% vs 73%). The maintenance randomization has met its primary endpoint demonstrating a 55% reduction in risk of progression or death for lenalidomide compared to no maintenance (HR 0.45 [95%CI 0.39-0.52], median PFS 37 vs 19 months, p<0.0001) This significant improvement was observed in each pathway TE: HR 0.46 [95%CI 0.36-0.58], median PFS 60 vs 28 months, p<0.0001. TNE: HR 0.44 [95%CI 0.36-0.53], median PFS 26 vs 12 months, p<0.0001. The benefit of lenalidomide maintenance on PFS persisted across risk subgroups and was independent of induction therapy and response. An exploratory analysis of 132 patients stopping lenalidomide treatment for reasons other than disease progression (91 toxicity, 28 patient choice and 13 clinician choice) shows that patients receiving greater than 12 months of treatment have an improved median PFS compared to those stopping earlier (HR 0.35 [95%CI 0.18-0.68], 49 vs 31 months, p<0.0015). At this time 445 patients continue to receive lenalidomide maintenance on study. Of patients who have stopped therapy, only 21.5% did so due to toxicity. Relevant grade 3/4 adverse events were: neutropenia 35%, thrombocytopenia 7.4%, anaemia 4.4%, peripheral neuropathy 1.4%. Venous thromboembolism occurred in 2.3%. Second primary malignancy (SPM) data was collected and the relationship with maintenance therapy reviewed. 72 SPM were observed (24 no maintenance, 48 lenalidomide). Haematologic malignancy crude incidence was 0.3% vs. 0.9%. While we found a slight excess of SPM in older patients these were mostly non-invasive and did not impact the outcome benefit demonstrated. Conclusion The use of maintenance lenalidomide treatment results in highly significant improvements in PFS for patients of all ages and should be standard of care.

Abstract Abstract 130 In April 2006, the Spanish Myeloma Group (PETHEMA/GEM) activated a randomized phase III trial comparing TD vs. VTD vs. VBMCP/VBAD/Velcadeâ in patients 65 years-old or younger with newly diagnosed symptomatic MM, followed by ASCT with MEL-200. The primary end points were response rate after induction and after ASCT and time to progression. TD consisted of thalidomide 200 mg daily (escalating doses in the first cycle) and dexamethasone 40 mg on days 1–4 and 9–12 at 4-week intervals for 6 cycles. The VTD regimen was identical to TD plus Velcade 1.3 mg/m2 on days 1,4,8,11 of each cycle. Combination chemotherapy plus Velcadeâ consisted of 4 cycles of VBMCP/VBAD on an alternating basis followed by 2 cycles of Velcadeâ (1.3 mg/m2 on days 1,4,8, and 11 every 3 weeks). The duration of the induction therapy was 24 weeks in all arms. From April 6, 2006 to August 5, 2009 the 390 planned patients entered the study. As of December 31, 2008, 305 patients (median age: 57 yrs, M: 156, F:149; IgG. 181, IgA: 71, light chain: 43, others: 10) entered the study and are the basis of the current analysis. Fifty-six (18%) patients had soft-tissue extramedullary plasmacytomas (EMP) and the stage according to the ISS was I in 39%, II in 41 %, III in 19 % and unknown in 1%. The prognostic factors, including cytogenetics, was similar in the 3 arms. Fifty-five (18%) patients had high-risk cytogenetics (t(4;14), t(14;16) and/or 17p deletion). Two-hundred and ninety-nine patients (TD:103, VTD: 99 and VBMCP/VBAD/Velcade®: 97) were evaluable for response and toxicity to induction therapy. The ≥ PR rate was 64%, 82% and 75% with TD, VTD and VBMCP/VBAD/Velcade®, respectively (p=NS). The IF negative CR rate was significantly higher with VTD (29%) and with VBMCP/VBAD/Velcade® (25%) than with TD (14%) (p=0.009 and p=0.04, respectively). Progressive disease (PD) was significantly higher with TD than with VTD (21% vs. 8%, p=0.009). In the overall series, PD was significanty higher in patients with EMP (34% vs. 12%, p=0.0002) with a significanty higher PD rate for TD as compared with VTD (40% vs. 14%, p=0.05). In patients with poor cytogenetics the CR rate was significantly higher with VTD than with TD (42% vs. 5%, p=0.009). In this high-risk group the PD rate was higher with TD (37%) and with VBMCP/VBAD/Velcade® (23%) than with VTD (0%) (p=0.009 and p=0.04, respectively). The incidence of thrombotic events ≥ grade 3 was higher in the TD arm (9% vs. 1% vs. 3%, p=0.07 and p=0.01) while ≥3 peripheral neuropathy was higher with VTD (14% vs. 0% and 1%, p<0.0001 and p=0.0003). Treatment was discontinued due to toxicity in 11 patients (TD: 3, VTD: 6, VBMCP/VBAD/Velcade®:2). Eight patients died during induction period (TD:5, VTD: 2, VBMCP/VBAD/Velcade®: 1) One-hundred seventy-seven patients were evaluable for response after ASCT. The post-ASCT CR rate with TD, VTD and VBMCP/VBAD/Velcade® was 40%, 59% and 48%, respectively, being significantly higher with VTD than with TD (p=0.05). The estimated overall survival at 2 years is 82% with no significant differences among the 3 arms. TTP and PFS were significantly shorter with TD (p=0.05 and p=0.012, respectively). In summary, VTD results in a higher pre- and post-ASCT CR rate as well as in a lower PD rate than TD, particularly in patients with high-risk cytogenetics or with EMP. The TTP and PFS are shorter with TD. Intermediate results are observed with VBMCP/VBAD/Velcade®. Longer follow-up is needed to establish whether or not these results will translate into a significantly different long-term outcome. Updated data will be presented at the meeting.

Abstract BACKGROUND The original 3-arm CODEL design included a radiotherapy (RT)-alone control arm, an RT plus temozolomide (TMZ) arm, and an exploratory TMZ-alone arm. We report the analysis involving patients treated per the initial design. METHODS Adults (18+ years) with newly-diagnosed 1p/19q codeleted WHO grade III oligodendroglioma were randomized to RT (5940 cGy) alone (Arm A); RT with concomitant and adjuvant TMZ (Arm B); or TMZ alone (Arm C). Primary endpoint was OS, Arm A vs. B. Secondary comparisons were performed for OS and PFS, comparing pooled RT arms with the TMZ-alone arm. RESULTS 36 patients were randomized equally to the three arms. At median follow-up of 7.5 years, 83.3% (10/12) TMZ-alone patients had progressed, versus 37.5% (9/24) patients on the RT arms. PFS was shorter in TMZ-alone patients compared to RT-treated patients (HR=3.12; 95% CI: 1.26, 7.69; p=0.014). Death from disease progression occurred in 3/12 (25%) of TMZ-alone patients and 4/24 (16.7%) of RT-treated patients. OS did not statistically differ between arms, although this comparison was underpowered. After adjustment for IDH status (mutated vs. wildtype) in a Cox regression model, with IDH status and RT treatment status as co-variables (Arm C vs pooled A and B), PFS remained shorter for patients not receiving RT (HR= 3.33; 95% CI: 1.31, 8.45; p=0.011), and OS differences remained non-significant ((HR = 2.78; 95% CI 0.58, 13.22, p=0.20). Grade 3+ adverse events occurred in 25%, 42% and 33% patients (Arms A, B and C, respectively). Neurocognitive assessments, comparing baseline and 3 month timepoints, showed no significant differences between arms. CONCLUSIONS TMZ-alone treated patients experienced significantly shorter PFS than patients treated on the pooled RT arms, which remained significant when adjusting for IDH status. CODEL has been redesigned to compare the efficacy and toxicity of RT+PCV versus RT+TMZ. Clinicaltrials.gov Identifier: NCT00887146.

Risk Of Progression

Abstract Abstract 1935 Smoldering Multiple Myeloma (SMM) is an asymptomatic proliferative disorder of plasma cells (PCs) defined by a serum monoclonal component (MC) of 30 g/L or higher and/or 10% or more plasma cells in the bone marrow (BM), but no evidence of end-organ damage. There are several risk factors predicting high-risk of progression to symptomatic disease (>50% at 2 years): >10% of PCs in BM, serum MC >30g/L, >95% aberrant PCs by immunophenotyping, or abnormal free-light chains. Standard of care of SMM is close follow-up without treatment until progression disease. Several trials have evaluated the role of early treatment with convencional agents (melphalan), bisphosphonates and novel agents (thalidomide, anti-IL1a), with no clear benefit, but they didn't focus on high-risk patients. In this phase III trial, SMM patients at high-risk of progression were randomized to receive Len-dex as induction followed by Len alone as maintenance vs no treatment in order to evaluate whether the early treatment prolongs the time to progresión (TTP) to symptomatic disease. The high risk population was defined by the presence of both >PC 10% and MC >30g/L or if only one criterion was present, patients must have a proportion of aberrants PCs within the total PCsBM compartment by immunophenotyping of 95% plus immunoparesis. Len-dex arm received an induction treatment consisting on nine four-weeks cycles of lenalidomide at dose of 25 mg daily on days 1–21 plus dexamethasone at dose of 20 mg daily on days 1–4 and 12–15 (total dose: 160mg), followed by maintenance until progression disease with Lenalidomide at dose of 10 mg on days 1–21 every two months (ammended in May 2010 into monthly). The 124 planned patients were recruited between October 2006 and June 2010, and 118 were evaluables (three in Len-dex and three in therapeutic abstention arm didn't meet inclusion criteria). This second interim analysis was planned when all patients were recruited. According to baseline characteristics, both groups were well balanced. On an ITT analysis (n=57), based on IMWG criteria, the overall response rate during induction therapy was 75%, including 51% PR, 12% VGPR, 5% CR and 7% sCR. If we select the group of 33 patients who completed the nine induction cycles, the ORR was 91%, including 15% VGPR, 9% CR and 9% sCR. After a median of 8 cycles of maintenance therapy (1-15), the sCR increased to 16%. After a median follow-up of 16 months (range:1-33), four patients progressed to symptomatic disease in the Len-dex arm: two of them during maintenance therapy after 24 and 28 months from inclusion and the other two progressed 3 and 8 months after early discontinuation of the trial due to personal reasons. In addition, nine patients have developed biological progression during maintenance, but in all but one of these, Len has been able to control the disease without CRAB symptoms (median of 9·5 months (1-18)). In the therapeutic abstention arm, 21 out of 61 patients progressed to active MM. The estimated hazard ratio was 6·7 (95%CI= 2·3-19·9), corresponding to a median TTP from inclusion of 25 months for the not treatment arm vs median not reached in the treatment arm (p<0.0001). It should be noted that 10 out of these 21 patients developed bone lesions as a symptom of active MM. Deaths in the Len-dex and no treatment arms were 1 and 2, respectively (p=0·6). As far as toxicity is concerned, during induction therapy, no G4 adverse events (AEs) were reported with Len-dex; 1 pt developed G3 anemia, 4 patients G3 asthenia 2 patients G3 diarrhea and 1 patient G3 skin rash; 3 patients developped G2 DVT. During maintenance, no G4 AEs were reported and only 1 patient developed G3 infection. In conclusion, this second interim analysis shows that in high-risk SMM patients, delayed treatment resulted in early progression to symptomatic disease (median 25 months), while Len-dex as induction followed by Len as maintenance significantly prolonged the TTP (HR: 6·7), with excelent tolerability; moreover, biological progressions occurring under maintenance have remained controlled over a prolonged period of time.
