Abstract Introduction: In systemic light chain (AL) amyloidosis free light chains produced by clonal plasma cells form amyloid fibrils that are deposited in tissues and organs resulting in organ dysfunction. Cardiac involvement by AL amyloidosis is frequent and the most critical prognostic factor. Prognostic evaluation in AL is based on cardiac biomarkers and patients with very high levels of both NTproBNP (≥8500 pg/ml) and cardiac Troponins (Mayo stage 3B) are at high-risk of early death and have a median survival of just 3-6 months in most series. The outcome of stage 3B patients has not improved despite the introduction of bortezomib-based therapies and there is an urgent need for new non-toxic treatments which can also lead to rapid and deep hematologic responses. Daratumumab, an IgGκ monoclonal antibody targeting CD38, has proved highly effective either alone or in combination with bortezomib, cyclophosphamide and dexamethasone and with good tolerability in AL amyloidosis patients. Methods: EMN22 is a phase 2, open-label, multicenter study planning to enroll 40 newly diagnosed patients with stage 3B AL amyloidosis from 5 sites in Greece, the Netherlands, Italy and France. Eligible patients should have high-sensitivity troponin T (hsTnT) >54 pg/mL and NT-proBNP ≥8500 pg/mL. Primary treatment consists of daratumumab monotherapy, initially administered intravenously at 16 mg/mL, and since February 2020 administered subcutaneously at a fixed dose of 1800 mg; weekly during Cycles 1-2, every 2 weeks for Cycles 3-6 and every 4 weeks thereafter. Patients who do not achieve a hematologic VGPR or better by Cycle 4 may also receive at investigator's discretion weekly bortezomib and low dose dexamethasone. Treatment continues until disease progression according to major organ deterioration progression-free survival criteria, start of new therapy, or for a maximum of 2 years. The current analysis includes patients who started treatment at least 3 months prior to the cut-off date (16 June 2021). Results: Among 17 patients included in this analysis, 9 (53%) are still on treatment and 8 (47%) have discontinued, either due to an adverse event (n=5, 29%), or due to disease progression (n=3, 18%). Most patients were males (n=12, 71%) and median age was 65 years (range 45-84). Eastern Cooperative Oncology Group performance status was 1 for 5 (29%), 2 for 11 patients (65%), and 3 for one patient (6%). Eight (47%) patients had New York Heart Association (NYHA) class II symptoms, and 9 (53%) NYHA class IIIA. At screening, median NT-proBNP was 13,994 pg/mL (range 8,816-40,428), median hsTnT 119.1 pg/mL (range 59.8-692) and median difference of involved to uninvolved free light chains (dFLC) was 553 mg/L (range 49-2823). Apart from the heart, the median number of other organs involved was 1 (range 0-5), with nervous system (n=8, 47%) and kidneys (n=7, 41%) most commonly affected. The median number of daratumumab infusions was 13 and the median duration of therapy with daratumumab therapy was 3.7 months. Overall, 5 patients (29%) started additional treatment with bortezomib after completion of 3 cycles of daratumumab monotherapy. All 17 patients had at least one treatment-emergent adverse event. Eleven patients (65%) had a serious adverse event (SAE); 9 (53%) had at least one cardiac-related serious adverse event, and one SAE (fatigue) was related to bortezomib. Six patients (35%) suffered a fatal SAE: sepsis (n=1), sudden death (n=3), and cardiac failure (n=2). Most common grade 3 or 4 non-serious AEs were peripheral edema (n=4, 24%), dyspnea (n=3, 18%), and atrial fibrillation (n=2, 12%), and only one non-serious neutropenia grade 3 was related to daratumumab. The overall response rate was 71%, with 3 patients (18%) achieving CR, 6 (35%) VGPR, and 3 (18%) a PR, with a combined CR+VGPR rate of 53% (9/17). One-, two-, and three-month overall response rates were 65% (n=11), 71% (n=12), and 71% (n=12), and the median time to first response was 7 days while the median time to at least VGPR was 14 days. The 6-month and 12-month OS rate were 70% and 53% respectively (median OS has not been reached). Conclusions: In this prospective phase 2 study, in patients with high-risk AL amyloidosis (stage 3B), daratumumab monotherapy shows a favorable safety profile and induced very rapid and deep hematologic responses with a median time to first response of 7 days, with 53% of the patients achieving VGPR or better and a 6-month OS of 70%.

Abstract Abstract 3866 Poster Board III-802 Bortezomib (Velcade®) retreatment has been shown to be active and well tolerated in patients with relapsed multiple myeloma (MM) in a number of retrospective studies and a small prospective phase 4 study (EVEREST). This large, prospective, international, multi-center, open-label phase 2 study was conducted to confirm the efficacy and safety of retreatment with bortezomib in MM patients who had previously responded (at least partial response [PR]) to bortezomib-based therapy as their most recent prior treatment. Patients had to have previously tolerated bortezomib 1.0 or 1.3 mg/m2 alone or in combination and have had a treatment-free interval (TFI; time from last dose of initial bortezomib treatment to first dose of bortezomib retreatment) of ≥6 months. Additional eligibility criteria included progressive disease or relapse from complete response (CR) by EBMT criteria, no MM therapy (except maintenance with dexamethasone, thalidomide, or interferon) since the last dose of initial bortezomib treatment, KPS ≥60, and adequate renal, hepatic, and hematologic function; patients with grade ≥2 peripheral neuropathy or neuropathic pain (as defined by NCI CTCAE v3.0) were excluded. Patients received bortezomib at the last tolerated dose (1.0 or 1.3 mg/m2) during initial treatment on days 1, 4, 8, and 11 for up to eight 21-day cycles, either alone or in combination with dexamethasone at the investigator's discretion. Response was assessed by EBMT criteria every 6 weeks during treatment and then every 2 months until disease progression. Adverse events (AEs) were graded according to NCI CTCAE v3.0. A total of 130 patients received at least 1 dose of bortezomib retreatment and were included in the safety population. Patients had a median age of 67 years, 57% were male, and 16% had KPS '70%. Median time from diagnosis of MM was 4.5 years (range 0–14 years); median number of prior therapies was 2; 15, 80, 23, and 12 patients had received 1, 2, 3, and ≥4 prior lines of therapy (excluding initial bortezomib therapy). Best response by EBMT criteria to initial bortezomib treatment was CR in 26% and PR in 74% of patients; median time to progression and TFI after initial bortezomib treatment were 17.9 months and 14.3 months, respectively. Last tolerated dose of previous bortezomib therapy was 1.3 mg/m2 and 1.0 mg/m2 for 62% and 29% of patients, respectively; 9% received another dose. Patients received a median 7.0 (range 1–8) cycles of bortezomib retreatment (23% of patients completed all 8 cycles); 72% of patients received concomitant dexamethasone. A total of 126 patients were evaluable for response. In the 126 response-evaluable patients, the overall response rate (ORR; CR+PR) by best confirmed response (EBMT criteria) was 40%; in addition, 18% of patients achieved minimal response (MR), to give a CR+PR+MR rate of 58%. After a planned secondary efficacy analysis, the ORR (CR+PR) by single best response was 55% (75% ≥MR). Median time to best confirmed response (≥MR) was 2.9 months; time to first response was 1.5 months. Analysis of ORR by patient subgroups showed comparable results in patients who did versus did not receive concomitant dexamethasone (42% vs 32%), in those who received ≤1.0 mg/m2 vs 1.3 mg/m2 bortezomib (35% vs 41%), and in those aged ≤65 years vs >65 years (45% vs 36%). ORR was 67%, 39%, 33%, and 25% in patients who had received 1, 2, 3, and ≥4 prior lines of therapy (excluding initial bortezomib), respectively. Analysis of best confirmed responses according to response to initial bortezomib showed that 63% and 52% of patients who achieved a CR or PR, respectively, to initial bortezomib treatment responded to retreatment. Most (98%) patients experienced a treatment-emergent AE; 60% experienced a grade 3/4 AE, and 32% experienced a serious AE; there were 8 deaths, 2 of which (due to sepsis and stroke) were possibly treatment-related. The most common grade 3/4 AEs were thrombocytopenia (35%), neutropenia (7%), diarrhea (7%), and pneumonia (5%). AEs leading to dose reductions or discontinuations were reported for 22% and 12% of patients, respectively. The incidence of neuropathy was 39%, including 9% grade 3; 4% of patients discontinued treatment due to PN; 61% of neuropathy events resolved or improved within a median 1.3 months. These results confirm that bortezomib retreatment is a well-tolerated, feasible, and active therapeutic option for heavily pretreated MM patients without evidence of cumulative toxicity.

Abstract Background: Melphalan in combination with dexamethasone is an active and the standard regimen in AL amyloidosis. Unfortunately very often patients relapse and other drugs are needed. Bendamustine is a bifunctional alkylating agent approved for the treatment of CLL, NHL, and MM in Europe and the US. But its safety and efficacy in AL amyloidosis is not known. In an effort to investigate the activity of Ben/Dex and improve the outcome of patients with relapsed AL we conduct a multi-center, Phase 2 study of Ben/Dex in AL (NCT01222260) and report data of an updated unplanned interim analysis. First data were reported at ASH 2014 (Abstr.3480). Methods: All patients had relapsed AL after a median of 2 prior therapies (range 1-4). Patients with very advanced cardiac involvement (NYHA Class IIIB/IV) were excluded. Patients with NYHA Class IIIA, NT-proBNP ≥ 1800 ng/L or BNP ≥ 400 ng/L, abnormal cTnT or cTnI could be included after evaluation by cardiology to determine the risk associated with the treatment. Patients with a CrCl ³ 15 mL/min were considered for the trial if they were not in active renal failure. This Phase IIa clinical trial uses a two-stage optimal Simon design enrolling 13 patients in the first stage. Since at least three patients experienced hematologic PR or better, the trial proceeded to the second stage treating an additional 16 patients. If 9 or more patients out of the total of 29 patients evaluable for response experience a hematologic PR or better, the treatment will be considered worthy of further development. The primary objective is to determine the partial hematologic response rate (PR). Secondary objectives included overall hematologic response (OHR) rate, organ response rate (OrRR) (Palladini et al., JCO 2012), time to failure (TTF), toxicities (adverse events at least possibly related to treatment), overall survival (OS) and the assessment of expression of genes associated with ER stress. Patients were assigned to bendamustine according to CrCl: CrCl ≥ 60 mL/min: 100 mg/m2 IV on day 1 and 2 of each cycle, CrCl 59-15 mL/min: 90 mg/m2 IV on day 1 and 2 of each cycle. The option to dose escalate was available to qualifying subjects including escalating to dose level (+)1: 120 mg/m2 (if CrCl ≥ 60 mL/min at the time of inclusion into the study) and 100 mg/m2 (if CrCl 59 - 15 mL/min at the time of inclusion into the study). Dexamethasone was started at 20-40mg weekly according to the performance status of the patient. The duration of each cycle was 28 days. Results: As of 7/15/15, 26 patients have received treatment and 28 patients have been enrolled. Median age of enrolled patients was 66 (range 44-77). Enrolled patients received a median of 1.5 prior regimens (range 1-4). Twelve of the enrolled patients received prior autologous stem cell transplant. Median number of cycles for treated patients is 3.5 (range is 1-12), with 4 patients still receiving treatment. Of note, only 2 patients discontinued treatment due to disease progression. Only 9 patients discontinued treatment due to AE. Most common drug-related AEs (all grades, >25%) included fatigue (39%), nausea (35%) and Anemia (27%),. No grade ≥3 drug-related AE occured in >20% of patients. Of note, no cardiac events were observed, including any increase in NT-proBNP.Of 24 patients eligible for response evaluation, 11 (46%) have responded hematologically, including (≥PR 42%, CR 4%). The median time to best response of treatment (partial response or better) was 1.57 months (range 0.97 to 15.1 months). The CR occurred in a patient after 5 cycles suggesting that this heavily pretreated patient population needs longer treatment to achieve response. Better responses were especially observed in less heavily treated patients. With a median follow-up of 13.4 months (range 1.5 to 30.3 months) the median OS has not been reached yet (Figure 1). The median PFS is 11.5 months (95% CI,1.5-29.1months) (Figure 2). Conclusions: In our updated unplanned interim analysis we found that Bendamustine in combination with dexamethasone is feasible and effective in pretreated AL amyloidosis with impaired organ function (NYHA IIIB and creatinine clearance of 30-15 mL/min were allowed). Cardiac events related to Bendamustine were not observed. Preliminary hematologic response rates are promising in this pretreated patient population, and organ assessments are ongoing. Further study of this approach is warranted. Figure 1. Figure 1. Figure 2. Figure 2.

Abstract Background: JAK1/2 inhibitor ruxolitinib (RUX) abrogates symptoms and organomegaly in patients with myelofibrosis (MF). Combination with azacitidine (AZA) may further improve its efficacy. Methods: We initiated a single institutional, single arm, prospective, phase 2 study of RUX AZA combination in adult patients with MF and < 20% blasts. Previous therapy with RUX or AZA was not allowed. RUX 5 - 20 mg orally twice daily was given continuously since cycle 1. AZA 25 - 75 mg/m2 on days 1 - 5 of each 28-day cycle was added starting cycle 4. Responses were assessed per International Working Group for Myelofibrosis Research and Treatment 2013 criteria (IWG-MRT). Enrollment cut-off for this analysis was December 31st, 2017 to allow > 6 months of follow-up for all enrolled patients. We plan to present updated results with additional 5 months of enrollment at the meeting. Results: Fifty two pts were enrolled on study between 03/2013-12/2017, and were evaluable for responses. Forty seven pts (84%) were treated with both agents (RUX and AZA), with a median of 25 cycles (range, 1-55). Median age was 66 years (range, 48-87). Thirty four pts (65%) had int-2/high DIPSS score, 40 pts (77%) had spleen ≥5 cm. Thirty pts (58%) were JAK2V617F positive. Among 36 pts tested for non-driver mutations (28-gene panel); 7 pts had ASXL1, 6 had TET2, 3 had IDH1/2 and 2 had EZH2 and TP53. After a median follow-up of 22+ months (range, 1-59+); 21 pts (40%) are on therapy with a median overall follow-up of 30+ months. The most common reasons for therapy discontinuation were elective stem cell transplantation (n=12), and uncontrolled disease (n=8), including progression to acute leukemia (n=4). Four pts (8%) primarily discontinued therapy due to drug related toxicity (cytopenias). Three treatment unrelated deaths occurred on study; one each due to sepsis, meningitis and metastatic melanoma. Thirty eight pts (73%) had objective response on a study (Table). Median time to response was 1.8 months (range, 0.7-19). Seven responses (21% of responders) occurred after the addition of AZA with a median time to response of 2 months. These responses included spleen and symptom clinical improvements in 26% and 16% of pts, respectively. In total, 26 (65%), and 23 (58%) pts had palpable spleen reduction by > 50% at any time on study, and at week 24, respectively. JAK2V617F allele reduction was noted in 13 (81%) of 16 evaluable pts. Thirty one pts (60%) had available bone marrow for sequential evaluation. Nineteen pts (61%) had a documented improvement in bone marrow fibrosis, collagen or osteosclerosis, with a median time to first response of 12 months (range, 6-18). The most common grade ≥3 non-hematologic toxicity on a study was infection (34%), constipation (21%), and nausea (14%). New onset of grade ≥3 anemia, thrombocytopenia and neutropenia occurred in 33%, 30% and 16% of pts, respectively. Conclusion: Concomitant RUX with AZA was feasible with overall IWG-MRT response rate of 73%, including >50% spleen reduction in 65% of pts. Moreover, 61% of pts achieved improvement in bone marrow fibrosis, collagen or osteosclerosis. ClinicalTrials.gov Identifier: NCT01787487. Table.

Background Pomalidomide is an immunomodulatory drug that has been approved for the treatment of relapse refractory myeloma. A previous small randomized phase 2 study in the United States showed that combination of Pomalidomide, cyclophosphamide and dexamethasone induce a greater response rate than pomalidomide and dexamethasone1. In our prior study, AMN0012, we should that in patients with sub-optimal response to pomalidomide and dexamethasone, the addition of cyclophosphamide can increase response resulting in improvement of progression free survival. In the current study, we seek to randomize Asian patients with RRMM between PCD and PD to confirm the benefit of PCD. Method We conducted a prospective randomized trial of pomalidomide (4mg daily for 21 days followed by 7 days rest) plus dexamethasone 40mg once weekly for 4 weeks with or without cyclophosphamide (400mg once a week) in patients with relapse and refractory myeloma that has to be refractory to lenalidomide and has prior exposure to proteasome inhibitors. Each cycle is 4 weeks. Patients from Singapore, Japan and Korea (NCT03143049) were included in this Asian Myeloma Network trial. The trial was started in Sep 2017 and is still ongoing. To date, 53 patients have been recruited so far. This interim report presents data available up till the data cut-off date of 24 June 2020. Results Forty-six patients have available base line information and safety data and is included in this interim analysis. 50% of patients are male and median age of the cohort is 68 years old. 39% and 28% of patients are International Stage System (ISS) stage 2 and 3 respectively. 20% of patients have abnormal creatinine clearance. Median prior line of treatment is 3. All patients are refractory to lenalidomide and 96% have prior exposure to bortezomib. In addition, 12 patients (26%) and 5 (11%) have been treated with Carfilzomib and Ixazomib respectively. 15 (33%) patients had prior high dose melphalan and autologous stem cell transplant. 20 (44%) patients required dose reduction of pomalidomide, cyclophosphamide or dexamethasone. 89% of patients experience adverse events (AEs) of any grade. Of the 297 episodes of AEs, 43% are grade 3 or higher, with 50% of these episodes related to the study drugs. 57% of patients experienced serious AEs (SAEs) of any grade. Of the 74 episodes of SAE, 89% are grade 3 or higher, with 49% of these episodes related to the study drugs. Almost all of these events are related to cytopenias and infections. 20 (44%) of the patients develop grade 3 neutropenic fever and 9 (20%) patients have grade 3 or higher pneumonia. Only 1 patient experienced grade 3 peripheral neuropathy, 1 patient develop grade 3 pulmonary embolism, 1 patient developed grade 3 venous thromboembolism, and 1 patient experienced grade 3 renal impairment. At a median follow-up of 10.9 months, 9 of the 46 patients have died, and 21 have progressed. Three patients withdrew due to toxicity. While the overall response of the study population is not part of this interim analysis, we assessed the response of patients from the National University Cancer Institute, Singapore which has the highest number of patients recruited to get an idea of the therapeutic efficacy. Of the 14 patients recruited at NCIS, 1 patient achieved CR, 3 VGPR, 7 PR, producing a response rate of 79%. Conclusion In this interim analysis of a prospective randomized study of pomalidomide and dexamethasone with or without cyclophosphamide in Asian patients, we demonstrated the feasibility and efficacy of this combination. Longer follow-up and final analysis of the study will be needed to ascertain the therapeutic advantage of PCD over PD in relapse and refractory myeloma that is refractory to lenalidomide.

Abstract Background Ruxolitinib is a potent JAK1/JAK2 inhibitor that has demonstrated rapid and durable reductions in splenomegaly, improved MF-related symptoms and quality of life (QoL), and prolonged survival in 2 phase 3 studies comparing ruxolitinib with placebo (COMFORT-I) and best available therapy (COMFORT-II). However, no clinical trial in pts with MF had been conducted in Asian countries, and only a limited number of Asian pts or healthy volunteers had been enrolled in any ruxolitinib study. Methods This study was an open-label phase 2 study evaluating ruxolitinib in Asian pts with PMF, PPV-MF, or PET-MF who had palpable splenomegaly ≥ 5 cm below the costal margin and intermediate-2– or high-risk MF by the International Working Group for Myelofibrosis Research and Treatment (IWG-MRT) criteria. Pts received starting doses of ruxolitinib 15 or 20 mg twice daily (bid) based on baseline platelet count (100-200 or > 200 × 109/L, respectively); dose adjustments balancing safety and efficacy were allowed to titrate each pt to their most appropriate dose. The primary endpoint was met if the proportion of pts achieving ≥ 35% reduction in spleen volume from baseline at week 24 was ≥ 27.5% as measured by MRI/CT. Symptomatic response was assessed as a secondary endpoint using the 7-day modified MF Symptom Assessment Form (MFSAF) v2.0 total symptom score (TSS) and European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30). The study was conducted in China (n = 63), Japan (n = 30), Korea (n = 17), and Taiwan (n = 10). The data cutoff date for this analysis was 7 June 2013. Results Overall, 120 pts were enrolled (PMF, n = 80; PPV-MF, n = 21; PET-MF, n = 19), and their baseline characteristics were as follows: median age, 61 years (range, 25-80 years); 51.7% female; 69.2% intermediate-2 and 30.8% high risk by IWG-MRT criteria; median palpable spleen size, 15 cm (range, 5-45 cm); median spleen volume, 2159 cm3; 55.8% of pts had prior exposure to hydroxyurea. The median follow-up was 8.44 months; 22.5% of pts discontinued treatment, primarily for adverse events (AEs; 9.2%) and disease progression (7.5%). The median duration of treatment was 8.44 months (range, 0.5-21.7 months), and the median daily dose was 20.64 mg/day in the 15 mg bid group (n = 46) and 36.11 mg/day in the 20 mg bid group (n = 74). All pts were evaluable for achievement of the primary endpoint, 101 pts remained on study and were evaluable at week 24, and 96 pts had nonzero scores on the MFSAF-TSS and were evaluable for a reduction from baseline. Most pts who had assessments at week 24 (91% [92/101]) had a reduction from baseline in spleen volume (Figure). The study met the primary endpoint, with 31.7% (38/120) of all pts achieving ≥ 35% reduction from baseline at week 24. Overall, 38.3% (46/120) of pts achieved ≥ 35% reduction from baseline in spleen volume at any time on study. As measured by the 7-day MFSAF, 49% (47/96) of pts achieved ≥ 50% reduction from baseline in TSS (median reduction, 47.2%). Pts experienced an improvement from baseline at week 24 in EORTC global health status/QoL (mean change, 5.2). The most common nonhematologic AEs (≥ 10%) regardless of relationship to study medication included diarrhea (25.8%), upper respiratory tract infection (17.5%), ALT level increased (15.0%), pyrexia (15.0%), AST level increased (13.3%), cough (11.7%), herpes zoster infection (11.7%), nasopharyngitis (10.8%), constipation (10.0%), gamma-glutamyl transferase level increased (10.0%), and headache (10.0%), and most were grade 1/2. Serious AEs were reported for 24.2% of pts, and 65.8% of all pts had grade 3/4 AEs. The most common new or worsening laboratory abnormalities were low hemoglobin (all grade 3, 55.7%), low lymphocyte (grade 3/4, 19.5%), low platelet (grade 3/4, 15.3%), and low ANC (grade 3/4, 7.6%) levels. AEs observed in this study were consistent with those observed in the 2 large phase 3 COMFORT studies. Six pts (5%) died on treatment or within 30 days of discontinuation. Summary/conclusions Findings from this study demonstrated that ruxolitinib was relatively well tolerated in Asian pts with MF and provided substantial reductions in splenomegaly and modest improvements in MF-associated symptoms. The AEs observed with ruxolitinib treatment in this study are consistent with those observed in the large phase 3 COMFORT studies, and there were no new AEs associated with ruxolitinib in Asian pts with MF.

Abstract Introduction Ofatumumab is a novel anti-CD20 monoclonal antibody which led to impressive single-agent responses of 47-58% in a phase 2 study of CLL patients (pts) with refractory disease (Wierda et al 2010). Unfortunately, response durations were short (median 5.6-7.1 mos). In order to improve upon these results, we combined ofatumumab with a novel pan-AKT kinase inhibitor, afuresertib (GSK2110183). The AKT pathway plays a centralized role in tumor differentiation, migration, proliferation and survival and is frequently aberrantly activated in CLL (Longo et al 2007). Single agent afuresertib is very well-tolerated with minimal myelotoxicity in relapsed/refractory hematologic malignancies (Spencer et al ASH 2011). We present an interim analysis of the initial 19 of 31 planned pts in an ongoing trial of ofatumumab and afuresertib in relapsed/refractory CLL. Methods Previously treated CLL pts who have received at least one prior fludarabine-containing regimen with disease progression are eligible. During the initial 6 month Treatment Phase, ofatumumab 2000mg IV is administered weekly for 8 doses, then once every 4 week cycle for 4 doses (dose/schedule identical to the pivotal phase 2 trial) with afuresertib 125mg orally daily. An initial 10 day Lead-in Phase with afuresertib alone allows for evaluation of pharmacodynamic (PD) changes in phosphoproteins and pharmacokinetic (PK) studies. Pts are assessed for safety and response on day 1 of each cycle. Pts achieving SD, PR or CR by the end of the Treatment Phase proceed to the Maintenance Phase with single-agent afuresertib for a maximum of 12 mos (12 cycles). Results Demographics: To date, 19 pts have been enrolled. Median age is 65 yrs (range 43-76), baseline median Hb 108g/L (range 80-145), absolute lymphocytes 29.7 x109/L (range 1.0-464.9), β2M 4.42mg/L (range 1.42-3.21), bulky nodes ≥5cm in 5 pts (32%), organomegaly in 8 pts (42%), del17p/del11q on FISH in 9 pts (47%), and ZAP70+ in 13 pts (68%). Eight pts (42%) were fludarabine-refractory; only 2 pts had received prior alemtuzumab. The median number of prior therapies was 2 (range 1-6). Toxicity: Hematologic: 4 pts (21%) developed Gr 3-4 neutropenia during at least 1 cycle; 1 pt (5%) had a febrile neutropenia event. Only 2 pts (10.5%) have developed Gr 3-4 thrombocytopenia, without bleeding. Nonhematologic toxicity: Most common related grade 3-4 toxicities were GI: dyspepsia (53%), diarrhea (37%), nausea (21%), temporally related to oral afuresertib and easily managed symptomatically. Infusion reactions to ofatumumab were frequent (12 pts; 63%) with grade 3 reactions in 3 pts. Five pts (26%) developed non-infectious pneumonitis, with 3 pts requiring hospitalization. Two pts with preexisting atrial arrhythmias sustained exacerbation with weekly ofatumumab infusions. Most infections were mild, with only 1 grade 3 cellulitis. Efficacy: Of the 19 response-evaluable pts receiving a median of 6 cycles (range 1-9), 8 pts (42%) have achieved a PR, 11 SD (58%), and no CR. Response onset was rapid at a median 0.9 mos (range 0.8-2.8). At a median follow-up of 6.8 mos (range 0.3-12.9 mos), 5 pts (26%) have progressed and one patient has died after cycle 1 on therapy due to progressive CLL. PD Studies: CD19+ cells are assayed for phosphorylated AKT and its downstream targets RAS40 and GSK3 in addition to phospho-proteins of alternative pathways including ERK and pS6 by multiplexed phospho-flow cytometry. Peripheral blood samples are collected at screening and on cycle 1 day 10, after dosing with afuresertib. Of the 7 patients evaluated thus far, 5 demonstrated constitutive AKT phosphorylation at baseline. Partial inhibition of AKT signaling evidenced by increased phosphorylation of AKT and inhibition of GSK3 and/or RAS40 phosphorylation in response to BCR stimulation was observed post-treatment, indicating target engagement by afuresertib. PK Studies: Afuresertib exposure (Cmax and AUC) was similar when afuresertib was administered alone or in combination with ofatumumab. Conclusion Preliminary results from this phase 2 study suggests that a combination of ofatumumab plus a novel oral AKT inhibitor, afuresertib, has activity in previously treated CLL and is generally well-tolerated with minimal myelotoxicity. Response data are encouraging but whether durable responses can be achieved requires more mature follow-up.

Abstract Introduction: Phase 2 single agent trials with lenalidomide and panobinostat in patients with relapsed or refractory HL have demonstrated overall response rates (ORR) of 19% (Fehniger et al., Blood 118:5119-5125, 2011) and 27% (Younes et al., JCO 30:2197-2203, 2012), respectively. We conducted a phase I/II trial to determine the dose limiting toxicity (DLT), maximum tolerated dose (MTD), and overall response rate (ORR) with combined lenalidomide and panobinostat in patients with relapsed HL. Methods: Patients with relapsed or refractory classical HL (cHL) or lymphocyte predominant HL (LP HL) after at least one prior therapy were eligible. Measurable disease > 1 cm, ejection fraction ≥ 45%, ECOG PS 0-2, QTc ≤ 450 msec, ANC ≥ 1200/mm3, platelets ≥ 100,000/mm3, AST/ALT ≤ 2.5 x the upper limit of normal (ULN), bilirubin ≤ 1.5 x ULN, and creatinine clearance 60 ≥ ml/min were also required. In the phase I trial, escalating doses of panobinostat (15 or 20 mg) days 1, 3, and 5 weekly were combined with lenalidomide 25 mg days 1-21 utilizing a 3+3 standard dose escalation design. DLT was defined during cycle 1 as grade 4 neutropenia or thrombocytopenia, grade 4 infection, grade 3 infection for > 7 days, treatment delays > 14 days, or other grade 3-4 non-hematologic toxicity. Twenty-eight days defined a cycle and patients could remain on therapy until disease progression. Response was assessed after cycles 2, 6, and every 4 cycles thereafter by International Harmonization Criteria (Cheson, JCO 25:579-586, 2007). Results: From Feb 2012 through June 2014, 22 patients (16 males) with cHL (n=21) and LP HL (n=1) and a median age of 45 (range 22-72) have been enrolled. Patients had received a median of 4 prior therapies (range 2-13), 9 patients were refractory to their most recent therapy, and 91% had stage III-IV disease at study entry. Ten patients had a prior autologous SCT, 1 patient had received prior allogeneic EBV-directed cytotoxic T-cells, 1 patient had a prior syngeneic transplant, and 1 patient had both prior autologous and allogeneic transplants. Eleven patients were enrolled in the phase 1 study at dose level (DL) 1 (25 mg lenalidomide + 15 mg panobinostat, n=6) and at DL 2 (25 mg lenalidomide + 20 mg panobinostat, n=5). Although there were no DLTs observed in cycle 1, 2 patients treated at DL 2 experienced grade 4 neutropenia and thrombocytopenia for > 14 days in cycle 2 and 3 of 5 patients were dose reduced to DL 1 in cycles 2 or 3. Therefore, DL 1 was expanded to 6 patients to ensure patient safety at this dose level and the phase 2 study was conducted at DL 1. Eleven patients have been treated in the phase 2 study. In all 22 patients, the median number of cycles completed on study was 4 (range 1-22). Grade 3-4 toxicities in all patients included neutropenia (59%), thrombocytopenia (41%), lymphopenia (27%), febrile neutropenia (27%), hypophosphatemia (9%), hypocalcemia (5%), QTc prolongation (5%), fatigue (5%), nausea/vomiting (5%), erythema nodosum (5%), transaminitis (5%), and unexplained altered mental status after administration of study medications (5%). Dose reductions were required in 10 patients (45%, 5 in the phase 2 study and 3 patients with multiple dose reductions) for febrile neutropenia, grade 3-4 neutropenia/thrombocytopenia, erythema nodosum, and transaminitis. Twenty-one patients have discontinued protocol therapy for PD (n=15), adverse events (n=5, including grade 4 neutropenia/thrombocytopenia or unexplained altered mental status after drug dosing), and to undergo elective CABG (n=1). ORR is 14% (2 CR and 1 PR) in 21 evaluable patients with complete responses in 1 patient with cHL and 1 patient with LP HL of 6 and 25 months duration, respectively. Conclusions: Combined panobinostat and lenalidomide appears to be well tolerated in patients with relapsed/refractory HL. Due to myelosuppression at higher doses, the recommended phase 2 dose of the combination is 25 mg lenalidomide days 1-21 with 15 mg panobinostat days 1, 3, and 5 weekly on a 28-day cycle. Accrual continues to the two-stage phase 2 trial, but based on preliminary data in the first 22 patients, the efficacy of combined lenalidomide and panobinostat appears similar to that previously reported with these drugs as single agents.

Abstract Background: Treatment options for multiple myeloma (MM) refractory (ref) to immunomodulatory drugs (IMID) and proteasome inhibitors (PI) are urgently needed. Epigenetic agents e.g. the pan histone deacetylase inhibitor (HDACi) panobinostat (pan) to modulate the acetylation of histones and oncogenic proteins are promising. Preclinically in MM, pan is syngeristic when combined with dexamethasone (dex), lenalidomide (len), and bortezomib (btz) (Ocio EM et al. Haematologica 2010). The phase 3 PANORMA 1 study of 768 patients randomized to receive IV btz and dex with either pan or placebo revealed a 3.9 month increase in PFS and increased CR rates with pan but at the cost of an increase in grade 3/4 diarrhea from 8% to 25% (San Miguel, Lancet 2014). The safety/preliminary efficacy of pan-len-dex was assessed in a phase 1b study (Mateos et al, ASCO 2010) but was complicated by high dose dex toxicities. The maximum tolerated doses were used for this phase 2 study, however, we attenuated the schedule so that pan is given thrice weekly every other week (instead of weekly) and dex is given only weekly (table 1). Methods: Inclusion criteria were patients with rel or rel/ref MM (including IMID/PI ref), measurable disease, adequate organ function and hematologic parameters. Patients previously treated with a HDACi or currently receiving QTC prolonging medications were excluded. The primary objective in this open label, single arm phase 2 study was to evaluate the best overall response rate (ORR). Secondary objectives were to evaluate safety, duration of response (DOR), and overall and progression-free survival (PFS). Each drug was administered at the doses and schedule shown in Table 1. Results: 26 evaluable patients with progressive disease (PD) at screening have been enrolled with a median age of 64 (44% > 65 yo) and a median of 2 lines of therapy over 4 years since diagnosis. High-risk molecular findings were present in 14 patients (54%), including 4 with del p53 and 10 with gain of 1q21 by FISH (4 with concurrent t(4;14)). 22 (85%) were len- ref, & 35, 54, 23% were ref to each: pomalidomide (pom), btz, & carfilzomib. Responses include 2 complete responses (CR), 4 very good partial responses (VGPR), 4 PRs, 9 minimal responses (MR), and 3 stable diseases (SD), for an ORR of 38%, CBR (>MR) of 73%, and a median DOR of 6 mos. The median PFS was 6.5 mos. In the 22 len-ref pts, there were 4 VGPRs, 2 PRs, 8 MRs & 3 SDs, with a median PFS of 5.5 mos. Responses were even seen in 10 pom-ref pts including 1 VPGR, 1 PR, and 4 MRs. Grade 3/4 toxicities (regardless of drug attribution) were primarily hematologic, with neutropenia (40%), thrombocytopenia (23%) and anemia (4%) respectively. Grade 3/4 nonhematologic AEs included infections in 5 (1 while neutropenic), 3 diarrhea (transient), 4 fatigue & 1 pulmonary embolus and 1 pt each with: neck pain, QTc prolongation & weight loss. Patients requiring dose reductions of len/pan respectively were 4/4 for ANC, 5/1 for plts, 1/1 for febrile neutropenia & 5 len for fatigue, & 1 pan for asymptomatic T wave inversions. No doses were held or reduced for GI toxicities. Preliminary results from RNA-seq of bone marrow (BM) aspirates comparing > PR responders (R) vs < PR non responders (NR) identify 261 differentially expressed transcripts (p<0.05). Network analysis revealed "Antigen Presentation/Cell mediated immunity" as a top network function with TLR3 and MHC Class II complex as focus molecules. Immunophenotyping of the tumor microenvironment showed increased CD1c+ myeloid dendritic cells in Rs and conversely, increased CD123+ plasmacytoid dendritic cells in NRs (p<0.05). BM cytokine analysis revealed higher IL-6 and alpha-interferon levels at baseline in Rs. Interestingly, protein levels of Cereblon, Ikaros and Aiolos were not significantly different in the 2 groups. Conclusions: In rel/ref MM, the completely oral pan len dex demonstrates encouraging ORR, DOR, and PFS, even in len-ref patients with high-risk molecular findings, indicating the essential role of pan in attaining responses. In notable contrast to PANORMA 1, this regimen is well tolerated with no significant GI toxicities and primarily expected hematologic toxicities. Updated results of planned 27 pts, including correlatives, will be presented at the annual meeting. Table 1.

Abstract OBJECTIVES Nilotinib is a potent, second generation inhibitor of BCR-ABL tyrosine kinase (TKI) and represent a standard of care for patients with chronic myeloid leukemia (CML), including accelerated phase (AP-CML). In 2005, we initiated a phase 2 study of nilotinib 400 mg twice daily as a frontline therapy in patients with AP-CML, and herein present the efficacy and safety data after a median follow-up of 68.4 months (range, 0.3-124.8). METHODS This was a prospective, single institution, phase 2 study in patients of age ≥18 years with a newly diagnosed, untreated AP-CML (except for <1 month of previous imatinib) defined according to MD Anderson criteria (Kantarjian, 1988). Patients were treated with nilotinib 400 mg twice daily (BID). Data are presented on an intention to treat analysis with a cutoff date of June 30st, 2018. Response criteria are standard. Fisher exact test and χ2 were used for analysis of categorical variables; and survival probabilities were estimated using the Kaplan-Meier method. Time to events (e.g., overall survival, event free survival) was calculated from the date of treatment to the date of an event or to last follow-up as previously reported (Cortes et al, 2010). RESULTS Twenty two patients of a median age of 53.7 years (range, 26-79.7) were enrolled. Table 1 summarizes clinical characteristics of all patients. The median treatment duration was 47.3 months (range; 0.3-124.4), and the median follow-up 68.4 months (range, 0.3-124.8). All patients discontinued study as of January 2017 due to planned study closure; but 11 patients (50%) continued on nilotinib off protocol at data cut-off (400 mg BID [3]; 300 mg BID [2]; and 200 mg BID [6]). Median time to treatment discontinuation in the remaining 11 patients was 12.9 months (range, 0.3-112); reason for discontinuation was: inadequate response [3], toxicity [2], non-compliance/financial [4]; elective discontinuation after sustained MR4.5 >2 years [1]; and death due to stroke [1]. Sixteen patients (73%) achieved complete hematologic response (CHR). Overall rates of CCyR, MMR, MR4.5 and CMR (undetectable transcripts with at least 100,000 ABL copies) were 73%, 73%, 55%, and 41%, respectively. Median times to CCyR, MMR, and MR4.5 were 2.9 months (range, 2.7-6.4), 5.7 months (range, 2.7-99.2) and 6.0 months (range, 2.7-36), respectively. Seven patients (32%) achieved sustained MR4.5 >2 years. In total, 4 patients lost their best achieved response (CHR [1], CCyR [2] and MR4.5 [1]) while on study. All events were associated with acquired ABL domain mutation; Y253H [2], T315I [1], and F359I [1] with a median time to detection of 16.7 months (range, 7-40). During the study conduct, one patient progressed to blast phase after 2 months on nilotinib. Two patients died while on study, one due to stroke and one due to unrelated medical condition, after being on therapy for 3 and 0.4 months, respectively. One patient electively discontinued nilotinib after being in sustained MR4.5 for 107 months, and remains in MR4.5 after 6 months off therapy. Estimated overall survival and event free survival at 5 years were 84% and 70%, respectively (Figures 1a & 1b). On univariate analysis, age >55 years was associated with lower rate of MMR (p = 0.034; HR 0.34; 95% CI 0.12-0.92); MR4 (p = 0.013; HR 0.25; 95% CI 0.08-0.75); and MR4.5 (p = 0.01; HR 0.15; 95% CI 0.04-0.63). Overall survival was inferior in patients older than 55 years (p = 0.014; HR 2.4; 95% CI 2.36-not estimated); and in those with > 1 AP-CML defining abnormality (p = 0.018; HR 9.53; 95% CI 0.98-92). The most frequent non-hematologic adverse events (AEs) were hyperbilirubinemia (63% of patients), rash (63%), hypertension (59%), and transaminitis (50%). Grade ≥3 AEs observed in more than one patient were hyperbilirubinemia (n=2), and transaminitis (=2). Two patients developed arterio-thrombotic AEs: stroke and myocardial infarction (one each). Hematologic AEs included (all grades; grade ≥3): anemia (36%; 9%), thrombocytopenia (32%; 14%) and neutropenia (14%; 9%). Two patients (9%) discontinued therapy due to nilotinib related AE, one for G3 peripheral neuropathy and one for G3 hyperbilirubinemia with G2 thrombocytopenia. CONCLUSION Nilotinib is safe and highly effective in patients with AP-CML, and induces fast and durable responses. More than 50% of patients can achieve MR4.5. Clinical trial.gov: NCT00129740.

Background Bone marrow neovascularization is a hallmark of multiple myeloma and progression is associated with a substantial increase in pro-angiogenic factors that promote bone marrow angiogenesis, including vascular endothelial growth factor (VEGF-A) and hepatocyte growth factor (HGF). At present, anti-angiogenic agents are not part of treatment strategies in multiple myeloma, neither alone nor in combination with approved agents. MP0250 is a first-in-class, tri-specific multi-DARPin® drug candidate neutralizing VEGF-A and HGF as well as binding to human serum albumin to increase plasma half-life. This is a report on early safety and efficacy of MP0250 in combination with bortezomib plus dexamethasone (Vd) in RRMM patients that have previously been exposed to proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs). Aims To assess the efficacy and safety of MP0250 in combination with bortezomib and dexamethasone in patients with RRMM (MiRRoR, NCT03136653). Trial Design This trial is recruiting adults ≥18 years of age with RRMM who have progressed after at least two prior treatment regimens including bortezomib and an IMiD. Patients were enrolled to receive iv MP0250 on day 1 + subcutaneous bortezomib 1.3 mg/m² on days 1, 4, 8, 11, oral dexamethasone 20 mg on days 1-2, 4-5, 8-9, 11-12 of each 21-day cycle. Patients will receive treatment until there is documented disease progression or unacceptable toxicity. Methods The primary endpoint is efficacy in terms of overall response rate (ORR) per International Myeloma Working Group criteria. Secondary endpoints include safety, immunogenicity, progression-free survival (PFS) and duration of response (DOR). Exploratory endpoints include overall survival, and pharmacokinetics. Exploratory biomarkers for HGF and cMET in bone marrow biopsies are detected by IHC; MM specific markers, circulating HGF and VEGF levels are measured using patient plasma samples. Results As of 01 July 2019, 20 patients (7 ongoing) received a total of 137 doses (1-33 cycles) of MP0250 at the maximum tolerated dose of 8 mg/kg on Day 1 of each 21-day cycle in combination with Vd. Median age was 61 years (46-76), median time since diagnosis was 6.7 years. Median number of prior therapies was 4 (range, 2-9). All 20 patients had prior exposure to IMiDs and PIs and 9 patients received PI-based regimens as their immediate prior line of therapy before start of MP0250 + Vd. Importantly, 6 out of these 9 patients achieved responses ≥ Partial Response (PR). Treatment had been discontinued in 40% of patients due to PD, 15% due to Adverse Event (AE), 5% due to physician's decision and in 1 case at patient's request. The most frequent drug-related grade 3/4 AEs were hypertension in 7/1 patients, thrombocytopenia in 4/1 patients, grade 3 proteinuria in 4 patients and grade 3 anemia in 4 patients. There were no infusion-related reactions. No treatment-related deaths were reported. 20 patients received ≥ 1 dose of MP0250 + Vd and had at least 1 assessment of response and were included in the efficacy analysis. 1 patient (5%) achieved Complete Response, 4 patients achieved Very Good Partial Response (20%) and 3 patients achieved PR (15%) for an ORR of 40%. DOR at cutoff date is 6 months (range, 2-21). Pharmacokinetic data show sustained exposure over multiple cycles with a mean half-life of 11 days (range, 6-17). No indication of ADA-mediated drug clearance was observed. Summary Combining MP250 at 8 mg/kg with standard doses of bortezomib and dexamethasone was generally well tolerated with discontinuation due to AE in only 15% of patients. No unexpected toxicity was observed and AEs consistent with the toxicity profile of the individual agents. Analysis of the preliminary efficacy results showed an encouraging ORR of 40%. Recruitment to this Phase 2 study is ongoing. Disclosures Knop: Janssen, AMGEN, Bristol-Myers Squibb, Celgene: Consultancy, Honoraria.
