Abstract Abstract 616 Background: We have shown the three drug combination of cyclophosphamide, bortezomib and dexamethasone (CyBorD) to be highly active therapy in newly diagnosed myeloma while allowing stem cell harvest and transplantation (Reeder et al. Leukemia 2009; 23:1337-1341). However, twice weekly bortezomib and high dose dexamethasone have been shown to cause significant toxicities. In a prospective Phase II we modified CyBorD by using bortezomib once weekly and reducing the dexamethasone to “low dose dex” after the first two cycles in an attempt to reduce toxicity (cohort 2). We report the efficacy and toxicity of this modified regimen and compare the results to standard CyBorD (cohort 1). Patients and methods: 63 untreated symptomatic patients were enrolled on this Phase II trial (33 on cohort 1 and 30 on cohort 2). All are evaluable for response and toxicity. Treatment on cohort 2 consisted of oral cyclophosphamide 300 mg/m2 and IV bortezomib 1.5 mg/m2 days 1, 8, 15 and 22 and dexamethasone 40 mg by mouth days 1-4, 9-12, 17-20 in cycles 1 and 2, then 40 mg po days 1, 8, 15, 22 in cycles 3 and beyond. Cohort 1 used standard dosing of bortezomib and high dose dexamethasone throughout. Each cycle was 28 days. Acyclovir and a quinolone antibiotic prophylaxis were routinely used. Patients were evaluated for response and toxicity every cycle and were offered stem cell harvest and transplant after the 4th cycle but could continue up to 12 cycles maximum. Results: The median age for all 63 patients was 61 (36-74) years and 48% were female. Durie-Salmon stages were 47% II and 50% III and ISS stages I 43%, II 36%, and III 21%. Twenty-four percent of patients were genetic high risk (t(4;14) or deletion 17). Cohorts I and II were matched for age, gender and ECOG PS. ISS stages were higher in cohort 1 than cohort 2 (II/III 67% vs. 44%). The intent to treat (ITT) ORR (≥PR) for all 63 patients (cohorts 1 and 2) is 90% with 60% ≥VGPR. For cohort 2 (modified CyBorD) the ITT overall response (≥PR) was 93% (CR: 5, nCR: 7, VGPR: 6, PR: 10) with 60% ≥VGPR and 40% ≥ nCR. Those completing all 4 cycles of therapy had 92% ORR (24/26) and 65% (17/26) ≥VGPR. A comparison of response rates in cohorts 1 and 2 is shown in table 1. These high and comparable response rates were associated with fewer grade 3+ adverse events (AE's) than in cohort 1 (37% vs. 48%) and no grade 3 peripheral neuropathy (PN). The median follow-up for all 63 patients is 12.4 (2.8-29.2) months and 95% of patients are alive with 87% free from progression. Conclusions: Modified CyBorD with weekly bortezomib and reduced dexamethasone retains the high activity seen in standard CyBorD, but is less toxic and more convenient. Interestingly, this modified regimen allowed higher overall doses of bortezomib (5.2 vs. 6.0 mg/m2 per cycle) yet overall neuropathy rates were similar. This combination of a weekly alkylating agent with bortezomib and dexamethasone is well tolerated and produces high response rates in newly diagnosed patients with multiple myeloma.

Abstract Introduction. The standard first-line treatment of young and fit mantle cell lymphoma (MCL) patients consists of a rituximab containing induction of CHOP and high dose ARA-C, followed by high dose consolidation and autologous stem cell transplant (ASCT). Thus far, almost all patients relapse after ASCT. Bortezomib is a proteasome inhibitor with activity in MCL. We investigated in a randomized phase II study whether there was any indication that maintenance therapy with bortezomib after ASCT could improve the outcome of treatment, measured as event free survival (EFS). Methods. Patients 18-65 years with newly diagnosed MCL were treated with 3 cycles of R-CHOP and 2 cycles of ARA-C (2 x 2 g/m2 iv d1-4) and rituximab (375 mg/m2, iv d11). Patients in PR or CR continued with ASCT after BEAM conditioning. Patients with a PR or CR after ASCT, with a neutrophil count > 0.5 x 109/l and platelets > 80 x 109/l were randomized between bortezomib and no further treatment. Bortezomib 1.3 mg/m2 iv was given once every two weeks, for 2 years, starting between 6 - 12 weeks after transplantation. Results . Between October 2007 and February 2012, 140 patients aged 34-66 years (median 57) were registered. Five patients were not eligible. The MIPI score was low, intermediate, high or unknown in 57%, 32%, 10% and 1% respectively. All eligible patients started induction treatment with R-CHOP. Two patients did not receive the first ARA-C cycle, because of progressive disease and physician decision. Hundred-fifteen patients (85%) received the BEAM and ASCT. Reasons to stop protocol treatment before ASCT were: progressive disease (PD) (n=6), inadequate stem cell harvest (n=3), excessive toxicity (n=3), other reasons (n=8). The response after ASCT was CR/CRu in 99 patients (86%), PR in 15 (13%), unknown in 1 (1%). Only 62 patients (45%), aged 34-65 years (median 56) were randomized between bortezomib maintenance and no further treatment. Two patients were randomized, but not eligible. Reasons for no randomization were: not eligible (n=30), patient refusal (n=14), excessive toxicity (n=2, and other reasons (n=7). In each treatment arm 30 patients were included. The patient characteristics were well balanced, except the MIPI score. In the no maintenance arm 21 patients (70%) had a low MIPI, compared to 15 patients (50%) in the bortezomib arm, and 6 (20%) versus 11 (37%) patients had an intermediate MIPI score. In both arms 3 patients (10%) had a high MIPI. Fifteen patients (50%) in the maintenance group continued bortezomib for 2 years. Reasons to stop earlier were excessive toxicity (n=6), PD/relapse (n=4), patients refusal (n=3) and other (n=2). The main adverse events during maintenance therapy were neurologic (CTC grade 2: 14%, grade 3: 4%), and infectious (grade 2: 11%, grade 3: 7%). Three patients developed a secondary malignancy: a basal cell carcinoma in the no maintenance group, a melanoma and a prostate carcinoma in the bortezomib group. With a median follow-up of the patients still alive of 50.9 months EFS at 4 years for all patients is 61%, and the overall survival (OS) 78%. The median follow-up of the randomized patients still alive is 42.9 months. The EFS at 4 years is 72% without maintenance versus 71% in the patients randomized for bortezomib maintenance. The OS at 4 years also shows no significant difference between the groups, 90% versus 93% respectively. Conclusion. There is no indication that bortezomib iv maintenance in a frequency of once every 2 weeks does improve the EFS of newly diagnosed MCL patients after intensive induction treatment with R-CHOP, double ARA-C and BEAM followed by ASCT.

Abstract Abstract 633 Introduction: This independent phase 2 trial was designed to evaluate carfilzomib (C) combined with thalidomide and dexamethasone during induction and consolidation for feasibility, response and progression-free survival (PFS) in patients with newly diagnosed symptomatic MM, who were candidates for high-dose therapy. Patients with symptomatic MM and measurable disease, age 15 to 65 and no significant co-morbidity were eligible. At diagnosis Fluorescent in situ Hybridization (FISH) was performed of recurrent translocations, trisomy 9, del(17p), del (13q) and add(1q) Patients received 4 cycles of carfilzomib at 20 mg/m2 on days 1 & 2 followed by 27mg/m2 on days 8,9,15,16 of cycle 1 and on days 1,2, 8, 9, 15 & 16 of all subsequent 28-day cycles, thalidomide 200 mg days 1 – 28 of a 28 day cycle and dexamethasone 40 mg days 1, 8, 15 & 22 of a 28 day cycle. Stem cell harvest was performed with cyclophosphamide 2 g/m2 and G-CSF. Following HDM (200 mg/m2) and autologous stem cell transplantation (ASCT), consolidation therapy consisted of 4 cycles of carfilzomib 27 mg/m2 days 1, 2, 8, 9, 15 & 16 of a 28 day cycle, thalidomide 50 mg days 1–28 of a 28 day cycle and dexamethasone 20 mg days 1, 8, 15, 22 of a 28 day cycle. The primary endpoint was response, other endpoints were complete response (CR) according to IMWG criteria, immunofixation-negative CR (sCR), VGPR all pre-and post HDM, PFS and overall survival (OS). An interim analysis was planned after 20 evaluable patients, primarily to guard against excessive toxicity and/or lack of response. Results: While recruitment is still ongoing, 34 patients have been included, of which the first 20 patients were are evaluated for response and toxicity, with a median follow-up of 5 months. One patient was excluded because unavailability of data. Median age was 60 yr and ISS stages I/II/III were 8/6/5, respectively. Four patients went off treatment because of intolerance to thalidomide (n=1), tumor lysis syndrome with renal failure (n=1) or respiratory infections (n=2). Adverse events CTC grade 3+4 included tumor lysis syndrome (n=2), metabolic disorders (n=4), cardiovascular including DVT (n=5), gastrointestinal (n=2), skin rash (n=2) and reversible renal failure (n=3). Peripheral polyneuropathy grades 1+ 2 was observed in 7 (35%) of patients, but no grade 3 or higher. Responses after cycle 1 were CR + sCR 5%, VGPR 32%, PR 47%, SD 10%, NE 5% and after induction overall CR + sCR 21%, VGPR 47%, PR 16%, SD 10%, NE 5%. Median time to maximum response was 1 cycle. Secondary analysis revealed that responses occurred across cytogenetic subgroups as determined by FISH, i.e. add (1q) (n=2), t(4;14) (n=2), del(17p) (n=1) and del(13q) (n=5). Stem cell harvest was accomplished with standard CD34+ yield in all patients and HDM/ASCT was performed with complete hematologic recovery in 4/4 patients. Conclusion: Carfilzomib combined with thalidomide and dexamethasone during induction and consolidation is feasible and effective. The complete data including response after consolidation will be reported at the ASH meeting. This EMN trial was registered as NTR2422. Carfilzomib and an unrestricted grant was provided by ONYX Pharmaceuticals.

Abstract Abstract 3884 Poster Board III-820 Background and Objective Thalidomide/dexamethasone (thal/dex) combination has shown high activity in newly diagnosed multiple myeloma (MM) (Rajkumar SV. at al, J Clin Oncol 2006;24:431-436). In newly diagnosed patients, lenalidomide/dexamethasone (len/dex) has demonstrated superiority compared with high-dose dexamethasone alone (Zonder JA et al, Blood 2007;110:77). Although both thal/dex and len/dex are active in newly diagnosed MM, no randomized trial has been reported comparing these two regimens, and unfortunately none are ongoing or planned. We compared the efficacy and the toxicity of thal/dex and len/dex as primary therapy in 411 newly diagnosed MM patients treated at the Mayo Clinic. Patients and methods 411 consecutive patients seen at Mayo Clinic between 2001 and 2008, who received induction with thal/dex (n=183) or len/dex (n=288) were retrospectively studied. Thalidomide was given at a dose ranging from 100 mg/day to 400 mg/day continuously; the lenalidomide dose was 25 mg/day, days 1-21 on a 28-day cycle. All patients received dexamethasone, either at high-dose (40 mg orally on days 1-4, 9-12, and 17-20) or at low-dose (40 mg orally day 1, 8, 15, 22); each cycle was repeated every 4 weeks. In addition, a case-matched subgroup analysis that adjusted for age, gender and transplantation status was performed among patients who received high-dose dexamethasone comparing the thal/dex (n=72) and len/dex (n=72) groups. Outcome was analyzed on an intention-to-treat basis. The Chi-square or the rank sum tests were used to compare variables. Time-to-event analysis was performed using the Kaplan-Meier method and all comparisons were determined by the log-rank test and by the Cox proportional hazards model. Results On intention-to-treat analysis, of 411 patients, 80.3% versus 61.2% patients, respectively in the len/dex group and in the thal/dex group (p < 0.001), achieved at least a partial response. A significant difference between the 2 groups was found in terms of both very good partial response or better (34.2% vs 12.0%, p < 0.001) and complete response rate (13.6% vs 3.3%, p < 0.001). Duration of therapy was significantly longer in len/dex patients as compared to thal/dex patients: 36.7% vs 12.6% of patients who did not stop treatment to receive SCT were still receiving therapy at 1 year (p < 0.001).Time-to-progression was significantly better in the len/dex group than in patients receiving thal/dex (median 27.4 vs 17.2 months, HR 0.64; 95% CI 0.44-0.93; p = 0.019). Similarly, progression-free-survival was significantly higher in len/dex patients (median 26.7 vs 17.1 months, HR 0.69; 95% CI 0.48-0.98; p = 0.036). This translated into an increase in overall survival (OS) (median not reached for len/dex group compared to 57.2 months in thal/dex patients, HR 0.60; 95% CI 0.40-0.92; p = 0.018). Survival advantages were evident in patients presenting with International Staging System Stage (ISS) I/II (HR 0.57; 95% CI 0.32-1.00; p = 0.052) at diagnosis but not in patients with ISS stage III in subgroup analysis. There was a trend toward better OS in len/dex group compared to thal/dex group both for patients who underwent transplant and for patients who did not. A similar rate of patients experienced at least one grade 3 or higher adverse event (57.5% vs 54.6% in len/dex and thal/dex groups, respectively, p = 0.568). However, the toxicity profile was different in the two groups: major grade 3-4 toxicities of len/dex were hematological, in particular neutropenia (14% with len/dex vs 0.6% with thal/dex, p<0.001) while the most common toxicities in thal/dex were venous thromboembolism (15.3% vs 9.2%, p = 0.058) and peripheral neuropathy (10.4% vs 0.9%, p < 0.001). The data on efficacy and safety shown above were also confirmed in the subgroup case-matched analysis which included only high-dose dexamethasone patients. Conclusions This cohort study shows the superiority of len/dex in terms of response rates and survival, compared to thal/dex. The toxicity profile of the 2 regimens is different and len/dex treatment, although more active, was not associated with increased toxicity (grade 3-4 AEs). These data need to be carefully evaluated and randomized prospective phase III studies are necessary to confirm these results and determine the optimal initial therapy for MM.

Abstract Abstract 837 Background: Combination therapy with cytotoxic chemotherapy and tyrosine kinase inhibitors has improved the outcome for patients with Ph+ ALL with durable remissions in some patients even without an allogeneic stem cell transplant. The dual Src and Abl inhibitor dasatinib has ∼325 times more potent in vitro kinase inhibition than imatinib against BCR-ABL with significant clinical activity in patients with imatinib-resistant lymphoid blast phase CML (CML-LB) and Ph+ ALL. Aim: To determine the efficacy and safety of combining chemotherapy with dasatinib for treating patients with Ph+ ALL. Methods: In this phase II trial, patients with newly diagnosed Ph+ ALL receive dasatinib 50 mg po bid (or 100 mg daily) for the first 14 days of each of 8 cycles of alternating hyperCVAD and high dose cytarabine and methotrexate. Patients in CR continue to receive maintenance dasatinib 50 mg po bid (or 100 mg daily) and vincristine and prednisone monthly for 2 years followed by dasatinib indefinitely. Results: We have enrolled in the study 34 patients with untreated Ph+ ALL and 7 patients with 1 prior cycle of chemotherapy (before Ph+/BCR-ABL+ status was known). Patients younger than 50 years old have received a median of 6 cycles (range 2-8) and patients 50 years and older have received a median of 6 cycles (range 1-8). 20 patients are receiving maintenance in CR and two have completed the entire treatment regimen. Median age is 51 years (range 21 – 79); 22 patients were older than 50 years, Median WBC at diagnosis was 13.6 × 109/L (range, 1-276 × 109/L). 12 patients had CNS involvement at presentation. All patients are evaluable for assessment of response to induction; 39 (95%) achieved CR after first cycle or were CR at start. Two patients died before response assessment from infections. Thirty-one of 39 (79%) evaluable patients achieved cytogenetic (CG) CR after 1 cycle; 4 had a major CG response (3 had 5% and one had 15% Ph+), 2 had insufficient metaphases, and 2 are unknown (no CG exam on day 21 marrow). To date, 22 patients (56%) have achieved complete molecular remission (CMR) and another 8 (21%) have achieved a major (but not complete) molecular response (MMR) at a median of 14 weeks from initiation of treatment (range 2 – 59 weeks). Minimal residual disease assessment by flow cytometry is negative in 35 (90%) patients at a median of 3 weeks (range, 2-18 weeks). The median time to neutrophil and platelet recovery for cycle 1 is 18 and 23 days and for subsequent cycles is 15 and 20 days. Grade 3 and 4 adverse events have included bleeding (GI, GU, soft tissue and subdural hematomas)(18), pleural effusions (9), pericardial effusion (1), reversible rise in creatinine (10), deep vein thromboses (6), pulmonary emboli (3), as well as diarrhea, infections, hypophosphatemia, hypokalemia, hypocalcemia, hyperglycemia, and elevated transaminases. With a median follow up of 13 months (range 1-33), 29 patients (71%) are alive and 27 (66%) are in CR; 4 patients died in CR; 1 from an unrelated cardiac event and 3 from infections. Three patients have undergone an allogeneic stem cell transplant. The median disease free survival is 48+ weeks (range,1 to 140+) and the median overall survival is 52+ weeks (range, 3 to 143+). Eight patients have relapsed with a median response duration of 51 weeks (range 23-73) and 6 of them have died. In 5 patients morphological relapse was preceded by flow and molecular relapse. Five relapsed patients had ABL mutations (3 T315I, 1 F359V, and 1 V299L). Conclusion: Combination of chemotherapy with dasatinib is effective in achieving long term remissions in patients with newly diagnosed Ph+ ALL.

Abstract Abstract 445 Background: Carfilzomib is a proteasome inhibitor that irreversibly binds its target and has a favorable toxicity profile that has shown significant activity in relapsed multiple myeloma (MM), leading to recent FDA accelerated approval. To achieve rapid and deep response in patients eligible for stem cell transplant, we combined carfilzomib with the regimen of cyclophosphamide-thalidomide-dexamethasone (CTD). We recently reported the results of the Phase I component of the trial (in which no MTD was reached) followed by the initial Phase II trial; however, with increasing evidence for the safe and effective use of higher doses of carfilzomib, we now report results from dose escalation extension of the Phase II trial. Methods: Newly diagnosed myeloma patients intended for stem cell transplant were eligible. All patients were treated on a 28 day cycle with Carfilzomib IV Days 1,2,8,9,15,16 (see Table 1 below for dosing per cohort) along with Cyclophosphamide 300 mg/m2 PO Days 1,8,15, Thalidomide 100 mg PO Days 1–28 and Dexamethasone 40 mg PO Days 1,8,15,22. We initially conducted a Phase I run in trial of 6 patients with no DLT observed before expanding to the Phase II portion of the study. The initial phase II regimen is shown below – as no DLTs were observed, we have now fully accrued to the Phase II dose level +1. Treatment was for 4 cycles with expected SCT post induction. The primary endpoint of the trial is the proportion of patients who have ≥very good partial response (VGPR) to treatment. All patients received herpes zoster prophylaxis and ASA daily. Results: A total of 38 patients have been accrued to the trial, 6 in the initial Phase 1, 21 in the initial Phase II, and the remaining at dose escalated cohorts. We are reporting the 27 patients who have completed therapy and will update with the dose escalated cohorts. Median age was 65 (range 27–74) and 52% were female. ISS Stage was advanced (II-III) in 56%. Best overall response rate during 4 cycles of CYCLONE at dose level 0 is 96%: CR 29%, VGPR 46%, PR 21% (1 pt achieved MR). Adverse events of grade 3 or higher at least possibly related to CYCLONE occurred in 12 (44%). Most commonly reported non hematological toxicities (all grades) included fatigue (67%), constipation (56%), lethargy (41%) somnolence (37%), malaise (30%) depressed level of consciousness (22%); however, grade 3/4 toxicities occurring in >5% were uncommon: thromboembolic event 11%) and muscle weakness (7%). Two cases of pneumonia required hospitalization. Eight patients (30%) developed grade 1 sensory neuropathy; no higher grade or painful neuropathy was evident. There were no cardiac events seen in greater than 5% of patients. Grade 3/4 hematological toxicities included neutropenia (15%) and lymphopenia (7%). All patients advancing to SCT successfully collected stem cells. One patient died on study from pneumonia. Conclusion: The 4 drug CYCLONE regimen is highly efficaceous with a response rate after only 4 cycles of 96% (75% ≥VGPR, 29% CR) at the current dosing level of carfilzomib IV 20/27 mg/m2 in newly diagnosed myeloma. Toxicities are manageable, with only grade 1 neuropathy and minimal cardiac or pulmonary toxicity. Increasing the dose of carfilzomib is feasible and updated results of dose escalated cohorts will be reported at 20/36 and 20/45 mg/m2.

Abstract Background Induction triplets utilizing at least one of the “novel drugs” and steroids with or without chemotherapy are considered current standard of care in newly diagnosed, symptomatic multiple myeloma (MM). Medically fit patients (pts) remain candidates for subsequent autologous (auto) stem cell transplant (SCT) while use of allogeneic (allo) SCT remains a matter of debate. As we had previously shown the RAD regimen to be well tolerated and highly effective in relapsed and relapsed/refractory MM, we evaluated this combination in first-line treatment. Methods The current phase II trial (DSMM XII) was designed to include a total of 190 pts up to 65 years of age with symptomatic MM. Four 4-week cycles of RAD (lenalidomide 25 mg/day, d 1-21; adriamycin 9 mg/m² as 24-hour infusion, d1-4; oral dexamethasone 40 mg, d1-4 and 17-20; pegfilgrastim 6 mg, d 6) preceded stem cell chemomobilization. Low-molecular weight heparin for prophylaxis of venous thromboembolic events (VTE) was mandatory. Pts received either tandem auto SCT (melphalan 200 mg/m²; Mel200) or auto followed by allo SCT. Allo SCT (preparative regimen: treosulfan/fludarabine) was reserved for pts featuring at least one cytogenetic or serologic risk factor who had a matched sibling or unrelated donor available. Lenalidomide maintenance was administered for one year following both tandem auto and auto/allo SCT. This is the second pre-planned interim safety and efficacy analysis. Results Eighty-nine pts with a median age of 54 (range, 30-65) years, who were recruited between August 2009 and October 2010, are evaluable. Fifty pts (56.2%) had ISS stage II/III disease and in all except three, molecular cytogenetic analysis was performed. Incidences of chromosomal abnormalities were as follows: deletion of (del) 13q, 24.7%; translocation t(4;14), 12.4%; t(14;16), 3.4%; and del 17p, 5.6%. Treatment-related mortality with RAD induction was 0% while 61.8% of pts had treatment-emergent SAEs. Seventeen pts (19%) experienced neutropenia of grades 1 to 4. Incidences of severe (grades 3/4) and febrile neutropenia were 5.6 and 1%, respectively. Seven pts each (8%) had pneumonia and VTE, respectively. Post-RAD-induction CR/sCR and at least VGPR rates were 9% and 47.2%, respectively. All 78 pts with at least stable disease successfully mobilized stem cells. Overall response rate (at least partial response, PR) following first SCT on an intention-to-treat basis was 83%. Twelve pts each (13.5%) achieved centrally confirmed complete response (CR) or stringent (s)CR, respectively, and 54 pts (60.7%) had at least very good PR (VGPR). Conclusions This interim analysis shows RAD to be very well tolerated and effective in first line treatment of symptomatic MM. Mel200 further increased rates of deep response (at least VGPR) achieved by RAD induction. We are currently comparing this regimen to bortezomib, lenalidomide and dexamethasone (VRd) in a phase III trial. Disclosures: Knop: Celgene GmbH: Honoraria.

Critical Determinant

Abstract Background: The depth and durability of hematologic response is a critical determinant of outcome in patients (pts) with light chain (AL) amyloidosis. Complete hematologic remissions (CR) following risk-adapted melphalan and stem cell transplant (RA-SCT) in pts with AL amyloidosis is associated with organ improvement and extended overall survival (OS). We have previously shown that using bortezomib and dexamethasone (BD) as consolidation following RA-SCT is associated with deeper hematologic responses and favorable outcomes. We have conducted a prospective phase II trial using BD as induction followed by RA-SCT and BD consolidation to determine the safety and hematologic and organ response rates of this treatment program for newly diagnosed, transplant-eligible pts with AL amyloidosis. Methods: Untreated pts with AL amyloidosis received 1-3 cycles of BD (B 1.3mg/m2, IV/SC, and D 40mg, IV/PO, days 1, 4, 8, 11). BD was discontinued before 3 cycles in patients who achieved CR. Pts were then assigned melphalan 100, 140 or 200mg/m2 based on age, renal function and cardiac involvement; Starting 3 months following RA-SCT, pts received six cycles of BD (B 1.3mg/m2, IV/SC and D 20mg, IV/PO days 1, 8, 15, 22) every 12 weeks as consolidation. Hematologic responses were assessed using International Society of Amyloidosis criteria (Palladini et al. JCO 2012) and organ responses using updated criteria (Palladini et al. Blood 2014), after induction, 3 months post RA-SCT, and at 12 and 24 months from treatment initiation. Patients with New York Heart Association Class III/IV heart failure, ECOG > 2 or > grade 2 neuropathy were ineligible. Results: Twenty pts, 70% male, with a median age of 60.1 years with renal (55%), cardiac (65%), liver/GI (15%) or nervous system (15%) involvement received BD induction and 18 patients have been transplanted. Two pts with cardiac disease died during BD induction (10% TRM); 85% of pts are alive with a median follow up of 28 mo. By intent to treat, 60% and 70% of patients achieved at least a very good partial response (>VGPR) following BD induction and RA-SCT, respectively. Overall, 95% of patients achieved hematologic responses (>PR) including 35% CR. Cardiac and renal responses were seen in 75% (N=8) and 60% (N=10) of evaluable pts at 1 year following treatment initiation. Most common grade >3 adverse events included GI (40%), Renal (30%), infectious (10%), and cardiovascular (10%); Grade 2 or higher neuropathy was seen in 40% of pts and warranted discontinuation of BD consolidation in 35% of pts. Conclusion: In newly diagnosed AL amyloidosis pts, BD induction followed by RA-SCT was safe and rapidly and effectively induced responses resulting in organ improvement. There was 10% TRM during BD induction and no deaths during transplant supporting the notion that early mortality in newly diagnosed AL pts is independent of treatment received. The high incidence of neuropathy may be related to the administration of BD on a twice weekly schedule and rendered some pts ineligible for post-transplant therapy. Whether transplant-eligible pts will ultimately derive more benefit from proteasome inhibitor induction versus consolidation is worthy of further study.

High Dose Melphalan

Abstract Background: High-dose melphalan and autologous hematopoietic stem cell transplantat (auto-HCT) is a standard consolidation therapy for eligible multiple myeloma (MM) patients due to superior survival outcome as compared to chemotherapy alone. However, patients remain at continuous risk of disease relapse following auto-HCT. Lenalidomide is active in newly diagnosed and relapsed MM and has synergistic activity with melphalan, but has not previously been incorporated into preparative regimen for auto-HCT. While high dose lenalidomide induces myelosuppression, the anti-tumor activity of lenalidomide is dose-dependent. Methods: We conducted a single center, phase I/II study of lenalidomide and melphalan in patients with MM undergoing auto-HCT. The phase I portion included MM patients at all disease stages, including patients undergoing auto-SCT as salvage therapy. The phase II portion enrolled patients undergoing a first auto-SCT after achieving at least stable disease following their induction regimen. Phase I objectives included determination of side effect profile and recommended phase II dose (RP2D). Phase II objectives were disease response at day +100 and toxicity. Treatment: All patients received a standard melphalan dose of 200 mg/m2 (100 mg/m2 IV days -1 and -2). Phase I lenalidomide dose was escalated from 50 mg, 75mg, 100 mg, and 150 mg and administered orally daily from days -7 to +2. Phase I data were previously reported (Blood (ASH Annual Meeting Abstracts), Nov 2012; 120: 3146). Thirteen patients were treated and no MTD was reached. The RP2D lenalidomide dose (150 mg orally daily days -7 to +2) was further explored in the phase II portion of this study. Post-transplant lenalidomide maintenance therapy was started between days +100 and +120 in all responders. We now report the planned interim analysis of the efficacy and safety profile of the phase II study. Results: From 5/1/12 to 7/9/15, forty seven subjects were enrolled to the phase II portion of the study. Study accrual is complete. We report below on the 37 patients with at least 100 days follow-up (median duration of follow-up of 12 months). 36 patients were assessable for response. Responses are as followed: stringent CR 8 (22%), CR 3 (8%), VGPR 20 (54%), PR 3 (8%), progressive disease 2 (5%). Among responders, 34 were able to start maintenance lenalidomide on days +100 to +110 (two withdrew from the study to pursue tandem stem cell transplant). To date, 21 patients remain on the treatment. Of 13 who discontinued the therapy; 4 was due to progression, 4 due to physician/patient preference, 2 due to toxicities and 3 from other reasons. Median progression free survival has not been reached. Toxicities were considered treatment related if they occur after the initiation of study drugs. DLTs are defined as any AEs occurring from days -7 to -2 that cause delay or prevent subjects from proceeding to auto-SCTs, grade 3 or more non-hematologic toxicities that do not resolve to a grade 2 or less by day 30 after auto-SCT, or engraftment failure. No DLTs were observed. The median time for ANC and platelet engraftment was 12 and 15 days and no delayed engraftment was observed. Toxicities and posttransplant hematopoietic recovery rates were similar to historical data observed with single agent high dose melphalan. Lenalidomide related toxicities occurred more commonly during the maintenance phase. Common toxicities occurring in more than 10% of patients were diarrhea (24%), peripheral neuropathy (21%) and fatigue (10%). Grade 3-4 toxicities occurred in 16% percent of patients: fatigue (5%), neutropenia (5%) neuropathy (3%), and thrombocytopenia (3%). Conclusion The use of high dose lenalidomide in combination with high-dose melphalan as a preparative regiment for auto-SCT is well tolerated. High VGPR or better disease response rates, compared to historical control, suggest that the preparative combination regimen may improve the depth of response. Stem cell rescue likely overcome lenalidomide induced myelosuppression. The study is now closed to accrual. Updated data on primary endpoints from all subjects will be reported at the meeting.

7019 Background: Aptamers are small synthetic oligonucleotides that form stable nuclease-resistant 3D structures and bind target proteins with specificity and affinity similar to antibodies. These “chemical antibodies” represent a new class of therapeutics. The AS1411 aptamer binds nucleolin on the surface of cancer cells and induces apoptosis. AS1411 has synergistic effects in combination with cytarabine on AML cell lines in vitro and in vivo. A phase I trial of AS1411 monotherapy in 30 patients with advanced cancer showed objective responses without serious toxicities. Methods: This open-label randomized phase II trial compared AS1411 plus high-dose cytarabine (HiDAC) with HiDAC alone in patients with primary refractory or relapsed AML who had received up to 3 previous lines of chemotherapy. Patients in cohort I were randomized 2:1 to receive AS1411 10 mg/kg/day as continuous IVI on days 1–7 + HiDAC 1.5 g/m2/ twice daily on days 4–7 or HiDAC alone for 4 days. Following safety assessment, a second cohort was randomized in a similar manner, with AS1411 escalated to 40 mg/kg/day. Objectives were comparison of response rates (CR+CRp), safety and tolerability between treatment groups. Results: Accrual has been completed, with 71 patients randomized: 22 to AS1411 10 mg/kg/day + HiDAC (AS1411–10), 26 to AS1411 40 mg/kg/day + HiDAC (AS1411–40) and 23 to HiDAC alone (control). Safety findings are currently available for 44 patients (AS1411–10, 21; AS1411–40, 9; control, 14). The main grade 3/4 toxicities were hematologic, notably febrile neutropenia, neutropenia, and thrombocytopenia; and infections. Safety findings were similar across groups, except that grade 3 hypokalemia was more frequent with AS1411–40. Deaths within 28 days of treatment were: AS1411–10, 1/21; AS1411–40, 1/9; and control, 2/14. Response data are currently available for 39 patients; response rates were: AS1411–10, 16% (3/19); AS1411–40, 14% (1/7); and control, 0% (0/13). Conclusions: Data from this first phase II trial of an aptamer in oncology are encouraging. The combination of AS1411 at 10 or 40 mg/kg/day with HiDAC appears well tolerated and shows promising signs of activity in patients with relapsed/refractory AML. [Table: see text]

Abstract Abstract 3052 The combination of bortezomib, doxorubicin, and dexamethasone (PAD) has shown efficacy in both relapsed/refractory and untreated, symptomatic multiple myeloma (MM). The activity of this regimen is largely attributed to the recognized synergy between bortezomib and doxorubicin. Bortezomib is capable of reversing resistance to chemotherapy in MM with adverse prognostic features (high-risk myeloma), which has an unfavorable outcome with conventional chemotherapy followed by high-dose therapy and autologous stem cell transplantation (ASCT). In addition, disease status prior to ASCT has prognostic significance for survival, underscoring the need for highly efficient remission induction strategies. In a prospectively designed phase II trial, we focused on the efficacy and safety of the PAD combination as front-line treatment for high-risk myeloma. The study recruited patients aged ≤70 years with newly diagnosed, symptomatic MM with high-risk features (defined by at least one of the following criteria: ISS stage II/III according to serum albumin and beta2-microglobulin, and/or detection of 13q deletion by FISH or conventional karyotyping). Between 2005 and 2008, 40 patients were enrolled in the protocol. The median age of patients was 59 years (range: 41–70 years), and 27 (67.5%) were male. Each 21-day cycle of PAD included bortezomib 1.3 mg/m2 on days 1, 4, 8, and 11 plus doxorubicin 9 mg/m2 on days 1–4, and dexamethasone 40 mg on days 1–4 and 8–11. According to protocol, patients received 4 induction cycles of PAD before proceeding to stem cell harvest and ASCT. Acyclovir and ciprofloxacin prophylaxis were routinely used. Patients were evaluated for toxicity at each cycle and for response after the end of the fourth cycle. The primary study endpoint was the response rate at the end of induction (assessed by the International Myeloma Working Group uniform response criteria, 2006). Secondary endpoints were toxicity, progression-free survival (PFS), overall survival (OS), ability to mobilize stem cells, and response after ASCT. ISS stage was I in 2 patients (5%), II in 18 (45%), and III in 20 (50%). Nine out of 40 patients (22.5%) presented with renal failure (creatinine >2mg/dl) due to myeloma at diagnosis. Deletion 13q was detected in 19 patients. Bone disease was present in 30 patients (75%) at diagnosis, and 19 (47.5%) had ≥3 lytic lesions on plain skeleton radiograms. Median patient follow-up time was 28.3 months (range, 1.4–49.3). All patients completed the 4 cycles of PAD, with the exception of one who died during the 2nd cycle. The overall response rate assessed after the 4th cycle of PAD was 95%. Complete remission (CR) was achieved in 12/39 (31%), very good partial remission (VGPR) in 15/39 (38.5%), and PR in 10/39 (25.5%). Thirty-one patients were considered eligible for ASCT, and an adequate stem cell harvest was achieved in all. Following ASCT, CR rate reached 52% (16/31) with a CR+VGPR rate of 84% (26/31). PFS was 67% at 2.1 years, and calculated OS was 81.4% at 4 years (Figures 1 and 2). Factors associated with shorter OS were beta2-microglobulin ≥5.5 mg/L (p=0.03), and ISS stage III (p=0.03). By assessment of the glomerular filtration rate (GFR), a significant improvement in renal function was demonstrated after induction with PAD (median GFR pre- and post-induction: 59.7 versus 82.1 ml/min, respectively; p<0.001). Improvement in kidney function was observed irrespective of the type of response. There was only one treatment-related death secondary to infection. Toxicities were manageable in general, and included grade 3–4 neutropenia in 8/40 patients (20%), grade 3–4 thrombocytopenia in 4/40 (10%), and grade 3 peripheral neuropathy in 4/40 (10%). No grade 4 peripheral neuropathy was encountered. We conclude that the PAD regimen is very effective, and produces high-quality responses in a substantial proportion of patients with newly diagnosed, high-risk MM (CR+VGPR: 69.5%). PAD is well tolerated and does not compromise stem cell mobilization and harvest. Upfront treatment with 4 cycles of PAD followed by ASCT resulted in notable PFS and OS rates in this patient group with adverse-prognosis MM. PAD was shown to be particularly beneficial in patients with renal impairment at diagnosis due to myeloma. Disclosures: Baltathakis: Janssen-Cilag: Research Funding. Terpos:Janssen-Cilag: Honoraria.
