Abstract Abstract 933 Follicular lymphoma (FL) is an incurable, indolent B-cell non-Hodgkin lymphoma. Although survival has improved with the introduction of rituximab (Rituxan®, R), relapse is inevitable and new therapies are needed. Bortezomib (Velcade®, V) plus rituximab is active in relapsed or refractory (rel/ref) FL (de Vos et al, ASH 2006). Bendamustine (Treanda®, B) plus R has also shown activity in rel/ref FL (Robinson et al, J Clin Oncol 2008), and V has been safely combined with B in patients (pts) with advanced multiple myeloma (Fenk et al, Leuk Lymph 2007). The single-arm, multicenter, phase 2 VERTICAL study was conducted to determine the efficacy and safety of V and R in combination with B (VBR) in pts with rel/ref FL. Here we report preliminary phase 2 efficacy and safety findings from pts treated with VBR at doses determined in the dose-escalation phase of this study (Matous et al, ASCO 2009). Pts with rel/ref FL who had received ≥4 prior doses of R (no prior V or B), and had ≥1 measurable tumor mass, no active central nervous system lymphoma, Karnofsky Performance Status (KPS) ≥50%, adequate hematologic, renal, and hepatic function, and no grade ≥2 peripheral neuropathy (PN) were eligible. Pts could receive up to five 35-d cycles of V 1.6 mg/m2 (d 1, 8, 15, 22), B 90 mg/m2 (d 1, 2), and R 375 mg/m2 (d 1, 8, 15, 22, cycle 1; d 1, cycles 2–5). Response was assessed by the investigator using International Working Group criteria (Cheson et al, J Clin Oncol 2007). Adverse events (AEs) were graded using the CTCAE v3.0, and by laboratory assessment of hematologic toxicity. Sixty-three pts received VBR; median age was 58 years, 63% were male and 25% had KPS ≤80%. At diagnosis, 47% had grade 1, 26% grade 2, and 8% grade 3 histology, and 18% unknown histology; 35% had high-risk Follicular Lymphoma International Prognostic Index score. Pts had received a median of 2 prior therapies (range 1–11), and 39% were refractory to their last prior rituximab-containing therapy. The median time from diagnosis was 48 months. As of data cut-off (14 Aug 2009), pts had received a median of 3 cycles (range 1–5); 29 pts remain on therapy and 10 have completed treatment. In the 49 pts with at least one post baseline response assessment, to date, the overall best response rate was 84%; 23 (47%) pts achieved a complete response (CR) and 18 (37%) a partial response (PR). VBR was generally well tolerated, with manageable toxicities. The most common treatment-related AEs were primarily grade 1 and 2 and included nausea (79%; 3% grade 3), fatigue (65%; 10% grade 3), diarrhea (57%; 3% grade 3), and vomiting (44%; 5% grade 3). Other non-hematologic grade 3/4 AEs that occurred in more than one pt included syncope (n=2; 3%) and PN (see below). Grade 3/4 neutropenia, thrombocytopenia, and anemia were seen in 25%, 6%, and 3% of pts, respectively. Treatment-related serious AEs were reported in 17 (27%) pts, including 3 (5%) with febrile neutropenia and 1 (2%) with grade 3 herpes zoster who did not receive antiviral prophylaxis and discontinued therapy. Of the 17 (27%) pts with treatment-related PN, only 4 (6%) had grade 3 (2 discontinued therapy; no grade 4); PN has resolved in 5 (29%) pts to date. There was one on-study death (cardiac arrest) that was considered treatment-related. Additional follow-up is required to assess long-term outcomes, including progression-free and overall survival. VBR is active in this heavily pre-treated, high-risk population, with high CR rates, and was generally well tolerated. Efficacy and safety data will be updated and reported at ASH.

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 Single-agent studies of lenalidomide in relapsed/refractory follicular lymphoma (FL) have demonstrated significant activity. Recent studies reported that the combination of lenalidomide and rituximab yields high response rates in patients with FL. Three recent phase 1 studies have shown that lenalidomide administered on 10 to 14 days of 21-day cycle of R-CHOP could be safe in the initial treatment of aggressive or indolent B-cell lymphomas. Two of these studies determined 25 mg of lenalidomide as the recommended daily dose. This multicenter, open label, phase 2 trial (NCT01393756) investigated the combination of lenalidomide with R-CHOP in patients (pts) with high burden FL. Methods Pts with previously untreated FL grade 1, 2 or 3a and a high tumor burden according to GELF criteria were eligible. Pts received an induction therapy with 6 cycles of R2-CHOP given every 3 weeks (25 mg oral lenalidomide on days 1-14) followed by two additional rituximab infusions. Pegfilgrastim was administered on day 4 and oral aspirin prophylaxis (100 mg) was given daily during the cycles. Lenalidomide dose was adapted to toxicities. Pts responding to induction therapy received rituximab maintenance every 8 weeks for 2 years. The primary endpoint was the complete remission (CR/CRu) rate, according to IWRC 99, at the end of induction treatment. Secondary endpoints were safety, progression free survival, duration of response and overall survival. Results Eighty pts were enrolled from 16 LYSA centres between December 2010 and January 2012. Median age was 57 y (range 29-71); 50% were male; 92% Ann Arbor stage III-IV; 28% B symptoms, 69% ECOG performance status = 0; 25% mass >10cm; 53% bone marrow involved; 40% LDH elevated; 63% FLIPI 3-5. Sixty-eight pts (85%) received the complete induction regimen. Median interval between R2-CHOP cycles remained 21 days during treatment. Thirty-three pts (41%) experienced at least one dose reduction of lenalidomide. The complete remission (CR/CRu) rate was 74% (CI 95%: 63%-83%) and ORR was 94% (CI95%: 86%-98%).Current median follow-up is 13 months. So far, 9 pts (11%) experienced a progression/relapse. Hematologic toxicity was in the range of that observed with R-CHOP regimen with 65% grade 4 neutropenia; 12.5% grade 4 thrombocytopenia; 7.5% febrile neutropenia and no toxic death. Grade 1-2 sensory neuropathy was observed in 28 pts (36%), one pt had a grade 3 neuropathy. Twenty-nine pts (36%; grade 1-2: 27; grade 3: 2) had reversible skin toxicity, usually during the course of the first cycle. Five episodes of thrombosis occurred during treatment or follow-up, 3 were related to venous access devices and only one required discontinuation of lenalidomide. Three cases of neoplasm were observed during follow-up. Conclusion The combination of 25mg of lenalidomide for 14 days with 21-day R-CHOP cycles is well tolerated and yields a high rate of complete remission in patients with high tumor burden follicular lymphoma.

Abstract Background: Previous trials from the Swiss Group for Clinical Cancer Research (SAKK) and the Nordic Lymphoma Group (NLG) showed that therapy with single-agent rituximab can produce long-term remissions in a sizeable subset of follicular lymphoma (FL) patients, with overall survival not inferior to chemo-immunotherapy, providing the rationale for the development of chemotherapy-free treatment strategies. Promising results have also been reported with the combination of rituximab and lenalidomide. The SAKK 35/10 phase-2 study was developed and conducted by the SAKK in cooperation with the NLG to compare the activity of rituximab plus lenalidomide versus single-agent rituximab in the first-line FL therapy. Methods: Patients with histologically confirmed untreated FL, grade 1, 2, 3a and in need of systemic therapy, were randomized either to rituximab monotherapy (R) (8 infusions of 375mg/m2 at day 1 of weeks 1, 2, 3, 4, and repeated at day 1 of weeks 12, 13, 14 and 15) or to rituximab (given at the same schedule) in combination with lenalidomide (RL) (lenalidomide given orally, 15 mg daily, starting 14 days before the first rituximab administration and continuously until 14 days after the last). The primary endpoint was the complete response (CR/CRu) assessed at week 23, defined according to the NCI standardized criteria (Cheson et al 1999). The study sample size was calculated to allow the detection of a 20% increase of the CR/CRu rate with RL over R, with 90% power and a type I error of 0.10. The 2 arms were compared using a one-sided Z-test with unpooled variance for proportions. Trial treatment was discontinued in patients who at week 10 did not achieve at least a minimal response, defined as reduction of more than 25% in the sum of product of tumor diameters (SPD), and rescue chemotherapy was given at the discretion of the treating physician. Results: In total, 154 patients were randomized; 77 (40 women and 37 men; median age 63yrs, range 29-85; 52% with stage IV and 47% with poor-risk FLIPI score) were allocated to arm R and 77 (42 women and 35 men; median age 61yrs, range 26-80; 48% with stage IV and 47% with poor-risk FLIPI score) to arm RL. Treatment was discontinued by 21 (28%) patients in arm R, in 16 due to lack of response at week 10 and in 1 due to toxicity, and by 19 (25%) patients in arm RL, in 3 due to lack of response at week 10 and in 13 due to toxicity. Adverse events of any grade were reported in 91% of patients in arm R and 100% in arm RL and adverse events of grade ≥3 were more common in arm RL than in arm R (51% vs 18% of patients). Grade 3-4 neutropenia was observed in 5% of patients in arm R and 19% in arm RL. The primary endpoint analysis (using the response assessment from the local investigators, reviewed by the study chairs) showed a significantly higher CR/CRu rate in patients treated with RL in comparison with those receiving R. This difference was observed both in the intent-to-treat (CR/CRu rate, 36% vs. 25%, respectively; p=0.056) and the per-protocol population (CR/CRu rate, 42% vs. 28%, respectively; p=0.049). Conclusions: The addition of lenalidomide to rituximab results in a significantly better CR/CRu at the cost of an expected increased toxicity. Further follow-up is needed to ascertain whether the response improvement will translate into prolonged time to next treatment and superior progression-free and overall survival rates.

Background Patients with Chronic Lymphocytic Leukemia (CLL) have an increased risk of infections both prior to and upon treatment. Infections are the major cause of death for these patients, the 5-year incidence of severe infection prior to treatment is approximately 32 % with a 30-day mortality of 10 % (Andersen et al., Haematologica, 2018). Chemoimmunotherapy is still 1st line standard of treatment for patients without del17p or TP53 mutation despite association with neutropenia, immunesuppression and infections. The combination of BTK inhibitors and the bcl-2 inhibitor venetoclax has demonstrated synergy in vitro and in vivo, while translational data indicate that the CLL-related immune dysfunction can be improved on treatment with reduced risk of infections. Employing the Machine-Learning based CLL treatment infection model (CLL-TIM) that we have developed, patients with a high (>65%) risk of infection and/or need of CLL treatment within 2 years of diagnosis can be identified (CLL-TIM.org). The significant morbidity and mortality due to infections in treatment-naïve CLL warrants trials that challenge the dogma of only treating symptomatic CLL. Thus, we initiated the randomized phase 2 PreVent-ACall trial of 12 weeks acalabrutinib + venetoclax to reduce risk of infections. Methods Design and statistics A phase 2, randomized, open label, multi-center clinical trial for newly diagnosed patients with CLL. Based on the CLL-TIM algorithm, patients with high risk of severe infection and/or treatment within 2 years from diagnosis can be identified. Approximately 20% of newly diagnosed CLL patients will fall into this high-risk group. First patient in trial planned for September 2019, primary outcome expected in 2021. Only patients identified as at high risk, who do not currently fulfil IWCLL treatment criteria are eligible. Patients will be randomized between observation in terms of watch&wait according to IWCLL guidelines or treatment. Primary endpoint Grade ≥3-Infection-free survival in the treatment arm compared to the observation arm after 24 weeks (12 weeks after end of treatment). Study treatment Acalabrutinib 100 mg BID from cycle 1 day 1 for 12 weeks. Venetoclax, ramp up during the first five weeks starting cycle 1 day 1, thereafter 400 mg once daily for a total of 12 weeks counted from cycle 1 day 1. Patients A sample size of 25 patients in each arm, 50 patients in total. Major inclusion criteria CLL according to IWCLL criteria ≤1 year prior to randomizationHigh risk of infection and/or progressive treatment within 2 years according to CLL-TIM algorithmIWCLL treatment indication not fulfilledAdequate bone marrow functionCreatinine clearance above 30 mL/min.ECOG performance status 0-2. Major exclusion criteria Prior CLL treatmentRichter's transformationPrevious autoimmune disease treated with immune suppressionMalignancies other than CLL requiring systemic therapies or considered to impact survivalRequirement of therapy with strong CYP3A4 and CYP3A5 inhibitors/inducers or anticoagulant therapy with vitamin K antagonistsHistory of bleeding disorders, current platelet inhibitors / anticoagulant therapyHistory of stroke or intracranial hemorrhage within 6 months Trial registry number EUDRACT NUMBER: 2019-000270-29 Clinicaltrials.gov number: NCT03868722 Perspectives: As infections is a major cause of morbidity and mortality for patients with CLL prior to any treatment, we aim at changing the natural history of immune dysfunction in CLL. The PreVent-ACaLL trial includes an optional extension into a phase 3 part with the primary outcome of grade ≥3 infection-free, CLL treatment-free survival two years after enrollment to address the unmet need of improved immune function in CLL for the first time.

Abstract Abstract 3286 Poster Board III-1 Introduction: Nilotinib, a potent and highly selective BCR-ABL kinase inhibitor, is approved for the treatment of patients (pts) with Philadelphia chromosome-positive chronic myelogeneous leukemia (Ph+ CML) in chronic phase (CML-CP) and accelerated phase (CML-AP) who are resistant or intolerant to prior therapy including imatinib. The ENACT study is a Phase IIIb, open-label, multicenter study that evaluated the efficacy and safety of nilotinib in adult pts with imatinib-resistant or intolerant CML in a clinical practice setting outside of a registration program. It is the largest single source of efficacy and safety information of any available tyrosine kinase inhibitor (TKI) in CML, particularly among the elderly. Methods: The present is a sub-analysis of the ENACT study on the efficacy and safety of 400 mg twice daily nilotinib in elderly (aged =60 years) pts initiating treatment in CML-CP who were resistant and/or intolerant to imatinib. Results: Of the 1,422 CML-CP pts enrolled in the ENACT study between January 2006 and October 2008, 452 (32%) were elderly (=60 years) at study initiation and 165 (37%) of these pts were =70 years [10 (2%) were =80 years]. Countries that enrolled =20 elderly pts include France, Italy, USA, Germany, UK, Spain, Canada, and Brazil. At study initiation, elderly pts had longer median durations of CML (<60: 51.1 months; =60: 69.3; =70: 66.6) and higher proportions with CML duration >5 years (<60: 43%; =60: 56%; =70: 52%). Besides imatinib, prior CML treatments received by elderly pts included dasatinib (=60: 20%; =70: 19%), cytarabine (=60: 23%; =70: 19%), busulfan (=60: 10%; =70: 7%), and interferons (=60: 50%; =70: 42%). Elderly pts were previously treated with imatinib for longer median durations (<60: 27.4 months; =60: 32.7; =70: 29.9), with higher proportions treated for >5 years (<60: 12%; =60: 19%; =70: 18%). The proportion of imatinib-intolerant to resistant elderly pts was about 1:1, which was higher than the proportion among <60 pts at about 0.6:1, such that relatively few elderly pts had prior highest imatinib dose >800 mg (<60: 34%; =60: 26%; =70: 21%). While response rates to prior imatinib were similar, among pts who required therapy after failing imatinib, elderly pts had lower cytogenetic response rates (<60: 22%; =60: 17%; =70: 19%) to prior dasatinib. During ENACT, less than 50% of elderly pts experienced nilotinib dose interruptions (=60: 46%; =70: 41%) and reductions (=60: 7%; =70: 6%) lasting >5 days, which was consistent with the overall ENACT dataset. The median duration of dose interruptions and reductions was 15 (=70: also 15) and 41 (=70: 32) days, respectively. The main reason for dose interruptions and reductions was adverse events (AEs). The median duration of nilotinib exposure was 227 days (=70: 219) and the median dose intensity was 749 mg/day (=70: 775). Efficacy was similar among elderly pts, with 39% (=70: 35%) of pts achieving complete hematologic response (CHR), 41% (=70: 39%) achieving major cytogenetic response (MCyR) and 31% (=70: 33%) achieving complete cytogenetic response (CCyR). MCyR rate was also similar among elderly hematologic responders (=60: 64%; =70: 65%). Among elderly pts requiring nilotinib therapy after both imatinib and dasatinib, and therefore have more resistant CML, CHR rate was 39% (=70: 32%), MCyR rate was 28% (=70: 29%) and CCyR rate was 20% (=70: 16%). Safety was likewise similar among elderly pts, with grade 3/4 study drug-related AEs occurring in 56% of pts (=70: 53%). The most frequent of these AEs were thrombocytopenia (=60: 24%; =70: 21%) and neutropenia (=60: 14%; =70: 11%). The most common method of managing these AEs was brief dose interruptions and/or reductions [thrombocytopenia (=60:86/108 pts; =70: 30/35), neutropenia (=60: 42/62 pts; =70: 9/18)]. Among elderly pts with prior dasatinib, 53% (=70: 58%) experienced grade 3/4 study drug-related AEs, while 7 out of 8 pts with pleural effusion on dasatinib no longer had it on nilotinib. Conclusions: In ENACT, pts aged =60 years at study initiation appear to have longer durations of CML, be more heavily pre-treated and more intolerant to imatinib than the younger cohort. Nonetheless, nilotinib induced comparable clinical responses in CML-CP pts regardless of age. Importantly, the safety profile of nilotinib is maintained in elderly pts.

Abstract Abstract 4937 Bortezomib (Velcade®) plus dexamethasone (Vel/Dex) is known to be effective and well tolerated in patients with multiple myeloma (MM). As demonstrated in the frontline setting, the addition to Vel/Dex of cyclophosphamide (VCD) or lenalidomide (Revlimid®; VRD) may lead to improved efficacy, but may be associated with increased toxicities; however, few studies have prospectively assessed Vel/Dex as second-line therapy. This randomized, open-label, parallel-group, phase 2 study in patients who have relapsed after or are refractory to primary MM therapy is designed to evaluate the safety and efficacy of an additional 4 cycles of Vel/Dex, VCD, or VDR in patients achieving stable disease (SD) after 4 cycles of Vel/Dex. Bortezomib-naïve patients aged ≥18 years, with measurable MM, KPS ≥60, life expectancy ≥6 months, adequate hematologic and hepatic function, and without grade ≥2 peripheral neuropathy (PN) received 4 3-week cycles of Vel/Dex (Vel 1.3 mg/m2 IV on days 1, 4, 8, and 11, and Dex 20 mg PO on days 1, 2, 4, 5, 8, 9, 11, and 12). Patients then received a further 4 cycles of therapy as follows: patients achieving at least a partial response (PR) received Vel/Dex; patients with SD underwent central randomization to receive Vel/Dex, VCD, or VRD; patients with progressive disease (PD) discontinued treatment. Here we report efficacy and renal function improvement in patients who had the opportunity to complete the initial 4 cycles of Vel/Dex as of April 2009, and safety data for patients who received at least 1 dose of study drug. Response was assessed by IMWG uniform response criteria based on measurement of serum and urine M-protein prior to treatment on day 1 of each cycle, at end of treatment, and monthly thereafter. Renal function as defined by calculated glomerular filtration rate (GFR; Cockcroft–Gault formula) was assessed prior to treatment on day 1 of cycles 1–5. Adverse events (AEs) were graded using NCI CTCAE v3.0. A total of 122 patients have been enrolled; by data cut-off (July 21 2009), 24 (20%) had not completed a single treatment cycle and are excluded from the safety population (N=98). Eighteen had received <4 cycles at data cut-off. Of the remaining 80 who were eligible for response, 63 had completed 4 cycles, 6 discontinued prior to completing 4 cycles (due to PD in 3 patients, death in 1, drug-related AEs in 2), 9 were not under treatment at data cut-off, and 2 had died. Their median age was 62 years (range 34–86), 55% were male, 21.3% had KPS ≤70; median time from prior therapy was 18.6 months. Response rate in the efficacy population was 41/80 (51%) after 4 cycles, including 8% CR. Median times to first and best response were 37 and 57 days, respectively. Patient renal function (by GFR) at baseline, median improvement in GFR, and responses achieved by the 10 patients in whom GFR improved by at least one renal function group are shown in the Table. Among the 98 patients who received at least one treatment dose, mean cumulative doses of bortezomib and dexamethasone were 14.6 mg/m2 (4.9, 4.5, 4.4, and 4.3 mg/m2 in cycles 1–4) and 478 mg (151.8, 145.6, 145.4, and 144.0 mg for cycles 1–4), respectively. Most patients (90%) reported AEs, including 39% with grade 3/4 AEs and 23% with serious AEs, within the first 4 cycles. The most common grade 3/4 AEs included thrombocytopenia (13%), anemia (7%), and pneumonia (6%). AEs resulting in dose reductions/treatment stop were seen in 21%/10% of patients. Incidence of sensory PN and PN was 29% (3% grade 3/4); most PN events were reversible, with 68% resolving within a median 53 days. Updated efficacy and safety data for the first 4 cycles of Vel/Dex for all patients enrolled by July 31 will be presented.

Abstract Introduction Fedratinib, a JAK2-selective inhibitor, demonstrated clinical benefit through a reduction in splenomegaly and symptoms in patients with myelofibrosis (MF), including post-polycythemia vera MF (post-PV MF), post-essential thrombocythemia MF (post-ET MF) and primary MF (PMF), in Phase I and II studies (J Clin Oncol 2011;29:789; Haematologica 2013;98:S1113). Bone marrow fibrosis (BMF) has been associated with splenomegaly and cytopenias (Ann Hematol 2006;85:226). Hence, stabilization and/or reversal of BMF remain important therapeutic goals. This report represents an exploratory analysis of sequential BMF data from patients with MF in an open-label Phase I/II study to evaluate the long-term effects of orally administered fedratinib (TED12015; NCT00724334). Methods Patients with intermediate or high-risk MF (Mayo Prognostic Scoring System) received fedratinib therapy in consecutive cycles (1 cycle = 28 days) as long as they derived clinical benefit. Bone marrow trephine biopsies were performed at baseline and after every 6 cycles. Hematoxylin and eosin, reticulin, and Masson's trichrome staining of core biopsy slides were used to grade BMF on a scale from 0 to 3 using the 2008 WHO MF grading criteria. BMF was graded independently in a blinded fashion by 3 hematopathologists. BMF grades were established as long as at least 2 of the 3 pathologists agreed independently. Changes in BMF grade from baseline were categorized as improvement (≥1 grade reduction), stabilization (no change), or worsening (≥1 grade increase). Results Of the 43 patients enrolled in the TED12015 study, the median fedratinib dose received was 473 (range 144–683) mg/day and median treatment duration was 32.3 (range 7–61) cycles. Bone marrow biopsies at baseline and at least one other time point were available for 21/43 (49%) patients, whose baseline characteristics were: median age 61 years (range 43–85); 57% male; 38% high-risk MF by WHO 2008 criteria (Leukemia 2008; 22:14); and 90% JAK2V617F positive. A consensus grade was achieved for 96% of the samples. At baseline, 2, 10, and 9 patients had grade 1, 2, and 3 BMF, respectively. Changes in BMF grade from baseline are shown in the figure. BMF improvement with 1 grade reduction was observed in 8/18 (44%) patients at Cycle 6. By Cycle 30, 4/9 (44%) evaluable patients had BMF improvement, including 2 patients with improvement by 2 grades and 2 patients with improvement by 1 grade. Of patients with Grade 3 BMF at baseline, 6/9 (67%) exhibited 1 grade improvement at Cycle 6. Two patients had 2 grades of BMF reduction from baseline during treatment (grade 3 to 1, and grade 2 to 0, both at Cycle 12), and the latter achieved a complete clinical remission at Cycle 30 assessed by IWG-MRT response criteria. The two patients who experienced complete reversal of BMF to grade 0 (one from grade 2 and one from grade 1) had normalization of not only hemoglobin level but also white blood cell and platelet counts at Cycle 18. Conclusions These exploratory analyses suggest that a proportion of patients treated long-term with fedratinib demonstrate stable or improved BMF. The disease modifying impact of fedratinib on BMF changes will be further assessed in a randomized, placebo-controlled Phase III clinical trial (JAKARTA; NCT01437787).

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: Multiple myeloma (MM) remains an incurable disease in need of new therapies with unique targets. Ibrutinib is a first-in-class, once-daily, oral, covalent inhibitor of Bruton’s tyrosine kinase (BTK), an essential enzyme in the B-cell receptor signaling pathway. While BTK is essential for the development and function of B cells and is down-regulated in plasma cells, the expression of BTK in malignant plasma cells is increased 4-fold and comparable to BTK expression levels in chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL). In addition, pre-clinical models show that BTK inhibition with ibrutinib led to direct inhibition of both osteoclast bone resorption and the release of osteoclast-derived tumor growth factors (Tai et al, Blood 2012). Taken together these data suggest that ibrutinib may have a role in the treatment of MM. Methods: This open label phase 2 dose escalation study was designed to enroll patients in 4 cohorts (Figure) to evaluate efficacy (≥MR) and secondary endpoints of safety, PK, ORR and DOR. Patients must have had documented non-responsive/progressive disease at the time of study entry following at least 2 prior lines of therapy including at least one immunomodulatory agent. Efficacy and safety were assessed at 4 weeks intervals using the IMWG response criteria for efficacy assessments (Rajkumar et al, Blood 2011), while safety was assessed according to CTCAE v4.0 criteria. Results: As of 15 May 2014 and a median follow up of 15.2 months, 69 patients with a median age of 64 years (range 43-81) were dosed, of which 20% had either a del 17p or p53 deletion. The number of median prior therapies was 4 (range, 2-14), 41% had ≥ 5 prior therapies and 80% had undergone autologous stem cell transplant. Sixty-two percent of patients were refractory to their last line of therapy and of the 65 patients that had received prior therapy with both an immunomodulatory agent and a proteasome inhibitor, 44% were refractory to both. Anti-tumor activity was noted across all cohorts. The highest activity with a clinical benefit rate (CBR) of 25% including 1 PR, 4 MR and 5 sustained (>4 cycles) SD was observed in Cohort 4. (Table) This led to expansion of Cohort 4 per protocol design. In Cohorts 1 and 3, 14 patients had dex added following PD, resulting in 1 PR and 9 SD. Overall, 57% experienced a Grade 3 or higher adverse event. The most commonly reported non-hematologic toxicities (any grade) were diarrhea (51%), fatigue (41%), nausea (35%), dizziness (25%), and muscle spasms (23%). The majority were Grade 1 and 2. Myelosuppression had a reported overall incidence of any grade anemia (29%), thrombocytopenia (23%), and neutropenia (7%) with 16%, 9% and 4% being Grade 3, respectively. There were no clinically meaningful differences among dose levels. Twenty-three patients experienced a SAE for a total of 47 reported events with 16 assessed as possibly/definitely related to ibrutinib per investigator. At least one dose modification occurred in 22% of patients, with 6 discontinuing due to an adverse event. At the time of the data cut-off 7 patients remain on study treatment. The most common reason for treatment discontinuation was PD in 47% of patients, with additional patients discontinuing due to investigator discretion (18%), patient decision (7%) and non-compliance (3%). Conclusions: In this heavily pre-treated patient population ibrutinib, as a single agent and in combination with dex, demonstrated evidence of anti-tumor activity. There was a trend toward improved efficacy (≥MR) in Cohort 4 and treatment was well tolerated with manageable toxicities. Ongoing correlative studies are being conducted to determine changes in cytokines, chemokines and indices of bone metabolism and to determine the effect of dex, a known CYP3A4/5 inducer, on the pharmacokinetic profile of ibrutinib. In addition, ibrutinib is currently being evaluated in combination with carfilzomib in an ongoing Phase1/2b study. (NCT01962792) Figure 1 Figure 1.

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.
