Introduction: AL amyloidosis is an incurable clonal plasma cell disorder characterized by tissue deposits of immunoglobulin light chain fragments leading to organ dysfunction and death. Standard treatment for newly diagnosed patients (pts) has traditionally included oral melphalan + dexamethasone as well as high-dose melphalan + ASCT. Although the combination of bortezomib, cyclophosphamide and dexamethasone (CyBorD) has activity, better tolerated treatment approaches are needed. Here we report preliminary results of a Phase 1/2, open-label, multi-institution study of ixazomib (I) in combination with cyclophosphamide (Cy) and dexamethasone (D) in newly diagnosed AL amyloidosis. Methods: Eligible pts are ≥18 years with newly diagnosed, untreated biopsy-proven AL amyloidosis according to standard criteria. A total of up to 30 pts will be enrolled, with up to 18 in the dose escalation arm (phase 1) and 12 in the maximum tolerated dose (MTD) expansion arm (phase 2) according to a classical 3+3 design. Four dose levels were evaluated in phase 1. I and Cy are given orally (PO) on days 1, 8, 15, and D 20mg PO on days 1, 8, 15, 22 of each 28-day cycle. Treatment continues for a total of 6 cycles or until disease progression, significant toxicity or withdrawal. The primary study objective in phase 1 is to establish the MTD and in phase 2 is to determine hematologic/organ response rate. Results: As of May 2019, 18 pts have been enrolled; 16 in phase 1 and 2 in phase 2. The MTD was established at dose level 3 (I 4mg and Cy 500mg). Median age is 65 years (range 46-79), 12 (67%) are male. Light chain isotype is lambda in 14 (78%). Seven pts (39%) have cardiac, 10 (56%) renal, 4 (22%) gastrointestinal, 1 (6%) hepatic, 2 (11%) soft tissue involvement, with 22% having multi-organ involvement. Four pts (22%) completed 6 cycles of therapy and 6 (33%) remain on study with a median of 3 cycles completed. Eight pts (44%) have been taken off study prior to completing 6 cycles due to no response in 5 (28%) after a median of 3.5 cycles (2-5), grade 4 hyperbilirubinemia unrelated to study drug in 1 (6%), cardiac decompensation in 1 (6%), and 1 death attributed to advanced disease. Eight of 16 pts (50%) had at least 1 drug-related adverse event (AE) (any grade), most commonly edema (19%), fatigue (19%), dizziness/lightheadedness (13%) and lymphopenia (13%). Grade 3/4 AEs were rare with grade 3 lymphopenia, anemia, and hyponatremia occurring in 13%, 6%, and 6% of pts, respectively. Of 18 evaluable pts, 7 (39%) achieved ≥VGPR with the median time to best response 2 cycles (1-5). Conclusion: The combination of ICyD for pts with newly diagnosed AL amyloidosis is safe and well tolerated. Phase 1 is completed and the recommended phase 2 dose has been established. Deep hematologic responses (≥VGPR) have occurred and time to response appears similar to standard of care induction regimens, ie CyBorD. Phase 2 response data will be updated at the meeting.

Abstract Introduction:"7+3" with standard doses of cytarabine and an anthracycline has remained the mainstay of induction chemotherapy for newly diagnosed AML. Since some studies have shown improved outcomes with high-dose cytarabine, cladribine, or escalated doses of anthracyclines, we conducted a phase 1/2 study (NCT02044796) of G-CLAM using escalated doses of mitoxantrone for newly diagnosed AML or high-risk MDS (>10% blasts). Methods: Patients≥18 years were eligible if they had treatment-related mortality (TRM) scores of ≤6.9 (corresponding to a predicted risk of early death with standard induction chemotherapy of ≤6.9%) and adequate organ function (LVEF ≥45%, creatinine ≤2.0 mg/dL, bilirubin ≤2.5 times upper limit of normal). Excluded were patients with uncontrolled infection or concomitant illness with expected survival <1 year. In phase 1, cohorts of 6-12 patients were assigned to 1 of 4 total dose levels of mitoxantrone (12, 14, 16, or 18 mg/m2/day, days 1-3, compared to 10 mg/m2/day used in standard dose G-CLAM previously established in relapsed/refractory AML). Other drug doses were G-CSF 300 or 480 μg/day (for weight </≥76 kg; days 0-5), cladribine 5 mg/m2/day (days 1-5), and cytarabine 2 g/m2/day (days 1-5). In phase 2, patients were treated at the maximum tolerated dose (MTD) of mitoxantrone. A second identical course of G-CLAM was given if complete remission (CR) was not achieved with cycle 1. Up to 4 cycles of consolidation with G-CLA (mitoxantrone omitted) were allowed if CR or CR with incomplete platelet or blood count recovery (CRp/i) was achieved with 1-2 cycles of induction therapy. Dose-limiting toxicities (DLTs) were: 1) grade 3 non-hematologic toxicity lasting >48 hours that resulted in >7-day delay of the subsequent treatment cycle; 2) grade ≥4 non-hematologic toxicity if recovery to grade ≤2 within 14 days, both excluding febrile neutropenia, infection or constitutional symptoms. Results: Among 33 patients (median age of 57.3 [range: 26-77], median TRM score 2.31 [0.16-5.90]) treated in phase 1, one DLT occurred at dose levels 3 and 4 (respiratory failure in both cases), establishing G-CLAM with mitoxantrone at 18 mg/m2/day as the MTD. Sixty-two patients, including 6 treated in phase 1, received G-CLAM at MTD. Patient characteristics were as follows: median age 58 (21-81) years, median TRM score 2.85 (0.06-6.73), with AML (n=52) or high-risk MDS (n=10). Cytogenetics were favorable in 6, intermediate in 44, and adverse in 12 (MRC criteria); 11 patients had NPM1 and 6 had FLT3 mutations. Fifty-two patients (83.9%, 95% confidence interval: 72.3-92.0%) achieved a CR (n=48 [77.4%: 65.0-87.1%]), or CRp/i (n=4 [6.5%: 1.8-15.7%]) with 1-2 cycles of therapy. Only 3 patients required 2 cycles to best response. Among the 48 CR patients, 43 (89.6%) were negative for measurable residual disease (MRDneg) by flow cytometry. Four patients had morphologic leukemia free state, 1 patient with myeloid sarcoma had a partial remission, 4 had resistant disease, and 1 died from indeterminate cause. One patient died within 28 days of treatment initiation (septic shock). Median times to an absolute neutrophil count ≥500/μL and a platelet count of ≥50,000/μL were 26 and 23 days. Besides infections and neutropenic fever, maculopapular rash, and hypoxia (fluid overload/infection-related) were the most common grade ≥3 adverse events. In addition to the phase 1/2 MTD cohort, there were 15 patients treated in an expansion cohort and 3 eligible patients treated off protocol with mitoxantrone at 18 mg/m2. For these 80 patients combined treated at MTD, the CR and CR/CRp/i rates were 76.3% and 81.2%. After multivariable adjustment, compared to 300 patients treated with 7+3 on the SWOG S0106 trial, G-CLAM with mitoxantrone 18mg/ m2 was associated with an increased probability of CR (odds ratio [OR]= 3.08, p=.02), CR/CRp/i (OR=2.96, p=.03), a trend towards improved MRDnegCR (OR= 3.70, p=.06), and a trend towards improved overall survival ([OS]; hazard ratio=0.34, p=.07). For the entire study cohort, the 6 and 12-month relapse-free survival were 73% (64-83%) and 62% (42-74%) and the 6 and 12-month OS were 89% (82- 96%) and 77% (67-88%). Conclusions: G-CLAM with mitoxantrone up to 18 mg/m2/day is well tolerated and has potent anti-leukemia activity. This regimen may warrant further randomized comparison with 7+3. We also plan to examine the addition of sorafenib to G-CLAM in newly diagnosed AML patients regardless of FLT3 status. Disclosures Othus: Glycomimetics: Consultancy; Celgene: Consultancy.

Background: We recently found that CLAG-M was safe and produced higher rates of CR/CRi and higher measurable residual disease (MRD)-negative CR (measured by multiparameter flow cytometry [MFC]) than standard "7+3" therapy in fit patients with newly-diagnosed AML or other high-grade myeloid neoplasm with ≥10% blasts (HG-MN). Since addition of the CD33 antibody-drug conjugate gemtuzumab ozogamicin (GO) to chemotherapy reduces relapse risk and improves survival in some AML patients, we conducted a phase 1 study (NCT03531918) to determine the maximum tolerated dose (MTD) of GO with CLAG-M in fit adults with newly-diagnosed AML (APL excluded) or HG-MN. Patients and Methods: Adults ≥18 years were eligible if they were fit (treatment-related mortality [TRM] score ≤13.1, corresponding to < 13.1% risk of TRM within 1 month) and had LVEF ≥45%, creatinine ≤2.0 mg/dL, and bilirubin ≤2.5-times upper limit of normal. Patients with concomitant illness with expected survival <1 year, with uncontrolled infection, or in myeloid blast phase of chronic myeloid leukemia were excluded. Doses were escalated in cohorts of 6 patients over 2 dose levels of GO ("GO1": 3 mg/m2 on day 1; "GO3": 3 mg/m2 on days 1, 4, and 7 [doses capped 4.5 mg]); the highest dose level achieved could then enroll an additional 6 patients (12 total) if ≤2 dose-limiting toxicities (DLTs) were observed. CLAG-M consisted of cladribine 5 mg/m2/day (days 1-5), cytarabine 2 g/m2/day (days 1-5), G-CSF 300 or 480 μg/day (for weight <76 kg vs. ≥76 kg; days 0-5), and mitoxantrone (18 mg/m2/day; days 1-3). A second course of CLAG-M (without GO) was given if MRD-negative CR/CRi was not achieved. DLT was defined as: 1) any grade 3 non-hematologic toxicity lasting >48 hours that resulted in >7 day delay of the subsequent treatment cycle, with the exception of febrile neutropenia/infection; 2) any grade ≥4 non-hematologic toxicity, with the exception of febrile neutropenia/infection or constitutional symptoms, if recovery to grade ≤2 within 14 days. The protocol was approved by the Fred Hutchinson Cancer Research Center Institutional Review Board. Results: We enrolled 18 patients, median age 66 (range: 28-77) years, median TRM score 3.92 (range: 0.14-10.3) with newly-diagnosed AML (n=14) or HG-MN (n=4); 7 were "favorable", 4 "intermediate and 7 "adverse" by 2017 European LeukemiaNet criteria. The first 6 patients were treated at GO1, with 1 DLT (grade 3 left ventricular systolic dysfunction). Two subsequent cohorts of 6 were treated at GO3. Three DLTs occurred at this second dose level (grade 4 aminotransferase level increase, grade 3 posterior reversible encephalopathy syndrome, grade 3 intracranial hemorrhage). As prespecified in the protocol, with ≤4/12 DLTs the MTD was formally not reached and GO3 was declared the recommended phase 2 dose. Among 18 evaluable patients, 13 achieved CR and 2 CRi for a CR/CRi rate of 83% (95% confidence interval: 59-96%). 13/15 CR/CRi patients were negative for MRD by MFC and cytogenetics for an MRDneg CR/CRi rate of 72% (49-88%). The 3 patients without CR/CRi had marrow aplasia without MFC evidence of AML at time of study removal. Two underwent allogeneic hematopoietic cell transplantation in aplasia; the other achieved later neutrophil recovery prior to AML recurrence 2.5 months following induction without interval therapy. 5/18 did not have platelet recovery to 100,000/µL prior to the next therapy/removal from study. Median time to absolute neutrophil count of 1000/µL (achieved in 16/18 patients) and platelet count of 100,000/µL (achieved in 13/18 patients) was 35 (range: 24-48) days and 31 (range: 26-48) days, respectively. Besides infections and neutropenic fever, hypertension and left ventricular systolic dysfunction were the most common adverse events. One patient had severe, self-limited liver toxicity characterized by weight gain and elevated aminotransferases without hyperbilirubinemia and did not meet typical clinical criteria for sinusoidal obstructive syndrome. There were no deaths within 56 days of starting induction in this study cohort. Conclusions: CLAG-M with fractionated-dose GO is feasible in patients with newly-diagnosed AML/HG-MN and appears to have high anti-tumor efficacy. CR/CRi and MRDneg CR rates were similar to what we observed with CLAG-M alone (86% and 71%, respectively). A phase 2 study based on these findings has been initiated, using event-free survival as primary efficacy endpoint.

Abstract Background: Recent advances have improved outcomes for patients (pts) with multiple myeloma (MM); however, novel agents targeting different pathways are still needed. Ibrutinib (ibr) is a first-in-class, once-daily, oral, covalent inhibitor of Bruton's tyrosine kinase (BTK), an enzyme overexpressed in malignant plasma cells, whose expression may positively regulate the myeloma stem cell-like population (Yang 2015). Clinical activity was observed at the 840-mg dose of ibr in heavily pretreated pts with relapsed or relapsed/refractory MM (RRMM), when combined with weekly dexamethasone (dex) (Vij 2014). Furthermore, BTK-mediated upregulation of NF-κB p65 contributes to proteasome inhibitor (PI) resistance in MM cell lines; thus, BTK inhibition with ibr may help overcome PI resistance (Murray 2015). In vitro, ibr has demonstrated synergy with PIs in MM (Rushworth 2013) and mantle cell lymphoma cells (Ou 2013). PCYC-1119 (NCT01962792) is an ongoing phase 1/2b study of ibr + carfilzomib (CFZ) ± dex in RRMM. Methods: Eligible pts received ≥2 prior therapies, including bortezomib (BTZ) and an immunomodulatory agent (IMiD) and had either no response or documented disease progression following the most recent treatment. Dose escalation followed a 3+3 design, followed by expansion of 2 cohorts (Table). Phase 1 primary objectives were maximum tolerated dose/recommended phase 2 dose (RP2D) determination and safety. Results: As of July 8, 2015, 40 pts were enrolled and received ibr combined with CFZ ± dex across multiple dose levels during the phase 1 portion. No dose-limiting toxicities (DLTs) were observed, and cohorts 2b and 3b were chosen for expansion to further evaluate safety and efficacy. Pts had a median age of 63 y (range, 44-83) and a median time from diagnosis of 4.3 y (range, 0.5-25.3). Cytogenetic assessment by FISH identified that 20% and 8% of pts had t4;14 and del17p, respectively. Overall, pts received a median of 3 prior lines of therapy (range, 2-11), including 10% prior CFZ, 25% pomalidomide, 25% thalidomide, 73% autologous stem cell transplant, and 100% BTZ and lenalidomide. Moreover, 88% of pts were refractory to their last therapy, with 73% refractory to BTZ, 73% refractory to lenalidomide, and 58% refractory both to IMiD and PI. No relevant differences were observed across cohorts. Thirty-six pts were evaluable for efficacy. With early follow-up, the initial objective response rate (ORR) was 58% and the clinical benefit rate (CBR) was 67%. In cohort 3b, the ORR and CBR were 65% and 77%, respectively, including 3 very good partial responses (VGPRs) and 1 stringent complete response (sCR). No clinically meaningful tolerability differences were seen between cohorts, and no new safety findings were observed. Across all cohorts, the most common all-grade nonhematologic adverse events (AEs) were diarrhea (43%), cough (35%), constipation and fatigue (30% each), and nausea (28%). Grade ≥3 hematologic AEs included thrombocytopenia (15%), anemia (13%), and neutropenia (5%). Grade ≥3 nonhematologic AEs occurring in ≥10% of pts were pneumonia and hypertension (15% each), diarrhea (13%), and fatigue (10%). Eleven pts reported treatment related SAEs. No clinically relevant differences in AEs were observed across cohorts. Ten pts discontinued study treatment due to progressive disease; an additional 6 pts discontinued due to an AE, and 6 pts discontinued due to investigator or pt decision. Duration of treatment ranged from 0.3 to 13.6 months, and 17 pts remain on treatment. Updated data will be presented. Conclusions: The initial phase 1 data indicated promising clinical potential for ibr + CFZ + dex, as it is well tolerated with no DLTs, no new toxicities, and no increase in the severity of known toxicities for the individual agents. The preliminary ORR of 58%, with 1 sCR and 3 VGPRs in cohort 3b, is encouraging in this mostly refractory patient population, especially with the high number refractory to BTZ. Cohort 3b was established as the RP2D and will be further evaluated in the phase 2 portion of the study. Table.

Abstract Abstract 431 Background: NPI-0052 has a novel, non-peptide based, bicyclic structure resulting in a unique proteasome inhibition and safety profile. In contrast to other proteasome inhibitors, NPI-0052 produces rapid, broad and prolonged inhibition of all 3 catalytic activities. Preclinical data subsequently suggested improvements in toxicology and efficacy, including activity MM resistant to bortezomib (BZ) and other agents (Chauhan et al, Cancer Cell 2005), thus this Phase 1 dose escalation trial in patients (pts) with relapsed/refractory MM was initiated. Materials and Methods: Patients (pts) were treated with NPI-0052 IV weekly for 3 weeks in 4-week cycles. Measurable disease by EBMT criteria was not required. The dose of NPI-0052 was escalated using a combination of accelerated titration and 3+3 design. PK and proteasome inhibition (blood and PBMCs) were assayed after the first and third doses. Preliminary Results: 27 pts have been treated at doses ranging from 0.025 to 0.7 mg/m2; median age is 62; 18 males/9 females; IgG/IgA/light chain/non-secretory 14/4/2/6; median of 4 prior regimens and 27% refractory to prior bortezomib. Reversible DLT was observed in two out of eight patients treated at 0.7 mg/m2 (Grade 3 fatigue; Grade 3 mental status changes and loss of balance), with 2 additional pts undergoing dose reductions in Cycle 1 (nausea and vomiting; vertigo and confusion/word-finding difficulties). Prophylactic anti-emetics have been instituted with a decrease in infusion-related nausea; similarly, pts with dizziness/vertigo have been administered meclizine with symptomatic improvement. Other drug-related adverse events have consisted principally of mild-to-moderate fatigue, nausea, vomiting, dizziness, headache and diarrhea; interestingly, myelosuppression, neuropathy and thrombosis do not appear to be elicited by NPI-0052. PK assessment demonstrates a rapid elimination half-life (<20 minutes) and relatively large Vz. NPI-0052 produces dose dependent proteasome inhibitions. At 0.7 mg/m2, Day 1/Day 15 inhibition of chymotrypsin-like activity in whole blood is 73% and 99%, respectively (the value for bortezomib at 1.3 mg/m2 is 65%). One patient with IgA MM (4 prior regimens plus ASCT; relapsed after prior BZ, not refractory) had a 71% decrease in M-protein (unconfirmed PR; off study after 3 cycles). A second pt with non-secretory disease (4 prior regimens;relapsed after prior BZ, not refractory) had a nearly 50% reduction in involved light chain; this pt remains active on study at 5+ months. In addition, 8 pts with relapsed/refractory MM remained on study for between 6-15 months (3 pts were on-study for over one year) with stable disease and no significant toxicity; 2 of these pts were BZ-refractory. Conclusions: Tolerability of 0.7 mg/m2 continues to be investigated in pts with MM, with prophylactic antiemetics and meclizine to reduce common drug-related toxicities of nausea and dizziness. The safety profile of NPI-0052 is importantly different from bortezomib in spite of higher and more durable proteasome inhibition; peripheral neuropathy and thrombocytopenia were not seen. Accrual continues to expand upon these results and assess the new lyophile formulation of NPI-0052.

Abstract Abstract 2737 Introduction: ATL is prevalent in Japan and has the worst prognosis among T-cell malignancies. PTCL also has a poor prognosis with currently available chemotherapeutic regimens, and both would benefit from better treatment modality. Lenalidomide is an immunomodulatory agent with direct tumoricidal and antiproliferative activity, and is approved for multiple myeloma (MM) in combination with dexamethasone after at least 1 prior therapy and for transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes associated with 5q deletion. We conducted a phase 1 study of lenalidomide in patients with relapsed ATL or PTCL to establish the recommended dose and schedule for a subsequent phase 2 study. Patients and Methods: This multicenter, phase 1, dose-escalation study assessed the safety, maximum tolerated dose (MTD), pharmacokinetics, and efficacy in patients with relapsed advanced ATL or PTCL. Dose-escalation was conducted according to the standard 3+3 design. Up to one PTCL patient was allowed to be included in each cohort of 3 patients. Patients in Cohort 1 received oral lenalidomide 25 mg daily on Days 1–21 of a 28-day cycle. Patients in Cohorts 2 and 3 received 25 and 35 mg/day, respectively, on each day of the 28-day cycle. Dose-limiting toxicity (DLT) was defined as febrile neutropenia lasting 5 or more days; thrombocytopenia (platelets <10,000/uL or bleeding requiring platelet transfusion); ALT/AST elevation of Grade 4 or that of Grade 3 lasting 7 or more days; and/or clinically unacceptable Grade 3 or higher other non-hematological adverse events (AEs). Treatment was continued until the development of unacceptable toxicity or progressive disease (PD). Response was assessed by internationally accepted standard criteria for ATL and PTCL. Results: From July 2010–June 2012, 13 Japanese patients (9 ATL and 4 PTCL; age 32–74 years [median, 64]; 1–11 prior therapies [median, 1]) were enrolled: 3 in Cohort 1, 6 in Cohort 2, and 4 in Cohort 3. The 3 patients in Cohort 1 received lenalidomide for 21, 103, and 637 days, respectively, until PD with no instances of DLT. In Cohort 2, 1 patient experienced DLT (thrombocytopenia, platelets <10,000/uL) and 4 patients received lenalidomide for 37, 56, 138, and 387 days, respectively, until PD in 3 patients and unrelated death in one. The sixth patient is still receiving lenalidomide for 28+ days without a DLT. In Cohort 3, 2 patients had DLTs (thrombocytopenia, platelets <10,000/uL in one patient and Grade 3 prolongation of QTc interval in one patient on concomitant fluconazole with preexisting cardiac disease and grade 1 QTc prolongation at baseline), 1 patient received lenalidomide for 71 days before withdrawal of consent, and 1 patient is still receiving lenalidomide for 323+ days without a DLT. Based on these results, 25 mg daily per 28-day cycle was regarded as the MTD. Other Grade 3/4 non-DLT AEs occurring in 2 or more patients included neutropenia (n=8), lymphocytopenia (n=7), thrombocytopenia (n=3), skin rash (n=3), hyperbilirubinemia (n=2), and increased ALT/AST (n=2). Among the 9 ATL patients, 3 achieved partial responses (PR) with hematological complete response in 2 patients, including the disappearance of skin lesions in 1 patient. These responses occurred between 54 and 57 days, and lasted for 92, 279+ and 505 days. Among the 4 PTCL patients, 1 achieved a PR at day 106 with >75% reduction in lymph nodes, which lasted for 282 days. PK profiles of patients in the study were generally consistent with that observed in Japanese MM patients. Plasma exposure of lenalidomide increased with increasing dose with a mean Cmax on Day 1 for 25 mg and 35 mg of 493 ng/mL and 628 ng/mL, respectively, and a mean AUC24 of 2774 ng/mL and 3062 ng/mL, respectively. There was no evidence of accumulation following multiple dosing for 8 days. Conclusions: This phase 1 study identified lenalidomide 25 mg daily per 28-day cycle as the dose and schedule for a subsequent phase 2 study in patients with ATL or PTCL. Based on the preliminary evidence of antitumor activity in ATL and PTCL patients, a phase 2 study in patients with relapsed ATL in Japan is planned. Disclosures: Off Label Use: Lenalidomide (CC-5013) is an investigational agent in Japan; this abstract assesses its use in adult ATL patients.

Abstract Introduction: Systemic amyloidoses are a group of rare disorders characterized by the accumulation of misfolded proteins in tissue, resulting in the dysfunction of vital organs (eg, heart and kidneys). In amyloid light chain (AL) amyloidosis, the most common form of systemic amyloidosis, the amyloidogenic protein is a misfolded light chain (LC) or a fragment of an LC produced by clonal plasma cells. Current therapies used to treat AL amyloidosis limit LC production but do not directly target deposits underlying multiorgan failure. NEOD001, a monoclonal antibody, targets misfolded LC and is thought to neutralize circulating LC aggregates and to clear insoluble deposits. In an interim analysis of a phase 1/2 dose-escalation study in 27 patients with AL amyloidosis and persistent organ dysfunction (NCT01707264; EudraCT2012-002683-27), monthly infusions of NEOD001 were safe, well tolerated, and associated with renal and cardiac responses.1 Here we report updated results from the escalation phase and new results from the expansion phase of this study. Patients and Methods: Inclusion criteria for this trial were that patients complete ≥1 PCD treatment before enrollment, attain partial hematologic response (HR) or better to any previous therapy, and have persistent organ dysfunction. NEOD001 was administered intravenously every 28 days. During the dose-escalation phase, 27 patients received NEOD001 at 0.5, 1, 2, 4, 8, 16, or 24 mg/kg in a 3+3 study design. An additional 42 patients with renal, cardiac, or peripheral nerve involvement were enrolled and treated (24 mg/kg) in the expansion phase. We assessed safety/tolerability, pharmacokinetics, immunogenicity, cardiac and renal responses based on consensus criteria, and neuropathy responses using the Neuropathy Impairment Score-Lower Limb (NIS-LL). Results: The 42 additional patients enrolled in the expansion study included cohorts with renal (16 patients), cardiac (15 patients), and peripheral nerve (11 patients) involvement. In the overall population (n = 69), the median age was 60 years, and 61% of patients were men. Median (range) time since diagnosis was 2.8 (0.4-12.8) years, and 45% of patients underwent ≥3 previous plasma cell-directed regimens. The total number of infusions administered was 913 over a mean of 13.2 (range, 3-35) months. NEOD001 treatment was not associated with dose-limiting toxicities or discontinuations; patients did not develop antidrug antibodies or treatment-related serious adverse events. The most frequent treatment-emergent adverse events, regardless of relationship to study drug, were fatigue, upper respiratory tract infection, nausea, and diarrhea. In a best response analysis, 53% of cardiac-evaluable patients (N = 36) and 63% of renal-evaluable patients (N = 35) met respective criteria for organ response; no patients experienced disease progression. The median time to initial response was 2 months (cardiac) and 4 months (renal). After 9 months of treatment, 82% of patients with measurable peripheral neuropathy at baseline (N = 11) achieved a peripheral neuropathy response based on the NIS-LL score. Conclusions: Our interim results demonstrated that monthly NEOD001 infusions were safe and well tolerated and that organ response rates compared favorably with traditional chemotherapy. These updated results from the escalation phase and these new results from the expansion phase, including results from patients with peripheral nerve involvement, support the design of ongoing late-stage clinical studies. Antibody therapy may allow for effective treatment of patients with AL amyloidosis. Reference: 1. Gertz MA, Landau H, Comenzo RL, et al.

Abstract Abstract 127 Two- and three-drug regimens incorporating bortezomib (Velcade®, Vc), lenalidomide (Revlimid®, Rev), dexamethasone (Dex), and cyclophosphamide (Cy) (Vc–Dex, Rev–Dex, Vc–Dex–Rev [VDR], and Vc–Dex–Cy [VDC]), have been shown to be effective and well tolerated in previously untreated multiple myeloma (MM). Combining Vc and Dex with Rev and Cy in a novel four-drug regimen (VDCR) may result in even greater activity with improved quality and duration of response. Results from the phase 1 dose-escalation portion of the multi-center EVOLUTION study showed that the VDCR regimen is a highly active and generally well-tolerated induction therapy in previously untreated MM patients (pts). Here we report the efficacy and safety of VDR, VDC, and VDCR from the non-comparative phase 2 portion of the study. Methods: Pts were randomized to receive up to eight 21-d cycles of VDR (Vc 1.3 mg/m2 d 1, 4, 8, 11; Dex 40 mg d 1, 8, 15; Rev 25 mg d 1–14) or VDC (VD as in VDR, plus Cy 500 mg/m2 d 1, 8) or VDCR (VDC plus Rev 15 mg d 1–14) as induction therapy, followed by Vc 1.3 mg/m2 (d 1, 8, 15, 22) for four 42-d maintenance cycles in all treatment arms. Pts received prophylactic antibiotics, acyclovir, transfusion support, and anticoagulants as required. Eligible pts wishing to undergo autologous stem cell transplant (ASCT) could undergo stem cell mobilization any time after cycle 2, and undergo ASCT any time after cycle 4. Response categories were based on the IMWG Criteria with the addition of near complete response (nCR). Adverse events (AEs) were graded using the CTCAE v3.0. Results: In the VDR, VDC, and VDCR arms 42, 32, and 43 pts (including 6 pts treated at the maximum planned dose of Cy (500 mg/m2) from phase 1) have been treated, and 42, 31, and 33 are evaluable for response, respectively, as of data cut-off (31 July 2009). Median ages in the VDR, VDC, and VDCR arms were 60, 62, and 62 years, respectively; 62%, 63%, and 66% had International Staging System stage lI/III disease, and 38%, 25%, and 33% had Karnofsky Performance Status ≤80%, respectively. The median number of VDR, VDC, and VDCR cycles received is 4.5, 6, and 4, respectively (range 1–12). Best unconfirmed response rates are shown in the Table; patients categorized as very good partial response (VGPR) include those who have no measurable M-protein but have not yet had bone marrow assessments to confirm CR/nCR status. The overall rates of treatment-emergent AEs were 95%, 97%, and 88% for the VDR, VDC, and VDCR arms, respectively, with ≥grade 3 reported in 67%, 59%, and 65%. Peripheral neuropathy (PN) was reported as grade 2/3 in 12%/12% in the VDR, 31%/3% in the VDC, and 12%/9% in the VDCR arms; there was no grade 4 PN reported. Grade 3/4 neutropenia was reported in 5%/5%, 28%/13%, and 23%/9% of pts in the VDR, VDC, and VDCR arms, and grade 3/4 thrombocytopenia in 5%/2%, 9%/0%, and 5%/0% of pts, respectively. One case of grade 3 deep-vein thrombosis was reported in the VDCR arm. Overall rates of serious AEs were 24%, 13%, and 37% in the VDR, VDC, and VDCR arms, respectively. Two pts have died in the VDCR arm, both due to renal failure, considered possibly treatment-related. To date, 6 pts have undergone ASCT in the VDR arm, 5 in the VDC arm, and 3 in the VDCR arm. Median CD34+ yield was 4.7, 6.3, and 6.8 × 106/kg in the VDR, VDC, and VDCR arms, respectively. Conclusions: VDR, VDC, and VDCR are highly active and generally well-tolerated regimens in previously untreated MM. Response rates in the VDCR arm appeared somewhat higher than in the VDR and VDC arms at this early time point, although there also appeared to be higher rates of serious AEs, including possible treatment-related mortality in the VDCR arm. Following an interim analysis, dosing in the VDC arm was modified to include Cy on day 15 to examine if this will improve CR rates. Ten pts have been enrolled to date.

Abstract Background. New standards with increasing efficacy that are also characterized with improving the quality of life are needed for elderly myeloma patients. Although MPT and MPV regimens are remarkable in terms of efficacy, quality of life while on treatment with these 2 regimens remain an issue. The Carmysap twice weekly carfilzomib-based phase 2 study has demonstrated that Carfilzomib at the MTD of 36mg/m² might challenge bortezomib in the VMP standard. However, it has become routine practice to use bortezomib on a weekly schedule, with maintained efficacy and an improved safety profile. We sought to demonstrate that Carfilzomib Weekly plus Melphalan and Prednisone will prove strongly efficacious with acceptable safety profile and quality of life to newly diagnosed elderly multiple myeloma (eNDMM). Methods . IFM2012-03 (also called carmysap weekly) is a phase 1/2 multicenter open label single arm study to determine MTD during the phase 1 part and VGPR+CR rate during the phase 2 part of the study. The inclusion/exclusion criteria of interest were eNDMM (65 and older), with symptomatic and measurable disease, with absolute neutrophils ≥1 G/L, untransfused platelet count ≥75 G/L, hemoglobine ≥8.5 g/dL and clairance creatinine ≥ 30ml/min. We report herein the phase 1 part of the study which last cohort was completed at ASH abstract deadline. For the phase 1 part of the study, each cohort was 6 patients based, and started at 36mg/m² of carfilzomib on days 1, 8, 15, 22 using IV, 30 minutes infusion, route followed by a 13-day rest period per 35-days cycles, melphalan given at 0.25mg/kg/j and oral prednisone 60mg/m², both on days 1 to 4. The subsequent cohorts' doses for carfilzomib were 45, then 56 and finally 70mg/m². 9 cycles were planned as induction followed by a maintenance phase of weekly carfilzomib monotherapy given at 36mg/m² weekly for one year. The MTD was determined when ˃2 DLTs were observed. DLTs were considered during cycle 1 if any hematologic toxicity of grade 4 intensity or preventing administration of 2 or more of the 4 carfilzomib doses of the first treatment cycle, grade ≥3 febrile neutropenia, grade ≥3 gastrointestinal toxicities, any other grade ≥3 nonhematologic toxicity considered related to CMP by the principal investigator, grade ≥ 3 peripheral neuropathy persisting for more than 3 weeks after discontinuation of study drugs. Results. 26 NDMM patients recruited, 24 treated in the study, 6 per cohort at 36 mg/m² carfilzomib +MP, then 45 then 56, and finally at 70mg/m² which cohort cycle 1 is up and running. The median age was 74 with 10 patients older than 75 and sex ratio M/F 65. There was a DLT at 36 mg/m² carfilzomib (grade 4 lymphopenia), one at 45 (lysis syndrome complicated with grade 4 renal insufficiency, two at 56 (cardiac insufficiency grade 3 and febrile neutropenia grade 3). At ASH deadline, all patients from cohort 36 of carfilzomib have completed induction and maintenance up to cycle 6, 5/6 of cohort 45 have completed induction and started the maintenance phase, 5/6 of cohort 56 have completed cycle 6 of induction and pursue within the induction phase, and finally all patients from cohort 70 of carfilzomib are undergoing cycle 1. There are 22 SAE reported for a total of 171 cycles administered of carfilzomib +MP. So far, 3 patients (out of 24) have stopped treatment, including the 2 patients with DLTs, lysis syndrome and cardiac failure, and one patient that presented with pulmonary hypertension later in the disease course on cycle 5 of the 56mg/m² carfilzomib +MP cohort. And, an extra 3 patients have had Carfilzomib dose reduction, 2 patients at 36 from 45 and one at 45 from 56, for neutropenia grade 4, thrombocytopenia grade 4, and Dyspnea grade 3, respectively. Conclusion. The MTD of weekly carfilzomib in the combination to Melphalan and Prednisone could be determined at 70mg/m² in elderly NDMM, demonstrating the good safety profile of carfilzomib in this regimen and fragile population. The complete dataset of the entire study will be updated at ASH with response rate, survival and safety profile.

Introduction: Risk stratification of patients with light chain (AL) amyloidosis at diagnosis is invaluable. Currently, the Mayo 2012 staging system is mainly used to risk-stratify patients. We evaluated the role of increased mean corpuscular volume (MCV) at diagnosis in predicting survival. Methods: We conducted a retrospective study of patients with newly diagnosed AL amyloidosis seen at Mayo Clinic, Rochester between January 2006 through December 2015. The diagnosis of AL was confirmed with biopsy and the determination of organ involvement was according to consensus criteria. Staging was done according to the Mayo 2012 staging system and patients with stage III/IV were considered to have advanced stage disease. Patient and disease factors were compared for categorical and continuous variables using the χ2 and the Wilcoxon signed rank tests, respectively. Overall survival (OS) was defined as the time from diagnosis to death of any cause. Survival analysis was done using the Kaplan-Meier method. Results: A total of 1064 patients were identified and were divided into two groups: those with an MCV ≥ 96 fl (Elevated MCV, n=180) and those with an MCV <96 fl (Low MCV, n=884). The median age at diagnosis for the whole cohort was 64, with an interquartile range (IQR) of 57-71. Overall, 222 (23%) had Mayo 2012 stage 1, 199 (21%) had stage 2, 239 (25%) had stage 3, and 290 (31%) had stage 4 disease. Patients with an elevated MCV were more likely to be more than 65 years old compared to patients with a low MCV (61% vs. 44%, p<0.0001). They were also likely to have an advanced Mayo 2012 stage (68% vs. 53%, P=0.0008). The median OS was significantly lower in patients with an elevated MCV compared to patients with a low MCV (median PFS 13 months vs. 41 month, respectively, P<0.0001)(Figure 1). On a univariable analysis, predictors of OS were advanced Mayo 2012 stage (RR 3.26, P<0.001) and MCV ≥ 96 (RR 1.6, P<0.0001). On the multivariable analysis, both variables remained predictors of OS [advanced Mayo 2012 stage (RR 3.19, P<0.001) and MCV ≥ 96 (RR 1.3, P=0.016)]. Conclusion: The median OS was shorter by 28 months in newly diagnosed AL amyloidosis patients with an MCV ≥ 96 compared to patients with an MCV<96. An elevated MCV was predictive of shorter survival, independent of the Mayo Stage. This variable is easily available, measured in all newly diagnosed patients, and provides valuable prognostic information for the treating physician.
