Abstract Background: RI occurs in ≈ 20%-30% of newly diagnosed MM pts and is associated with poor prognosis (Knudsen et al. Eur J Haematol. 2000; Kyle et al. Mayo Clin Proc. 2003). Data from 2 pivotal trials (MM-002, MM-003) suggested comparable efficacy and tolerability of POM + LoDEX in pts with or without moderate RI (Siegel ASH 2012; Weisel ASCO 2013). However, these trials excluded pts with severe RI. MM-013 (NCT02045017) is a European multicenter, open-label phase 2 study designed to assess the efficacy, safety, and pharmacokinetics of POM + LoDEX in RRMM pts with moderate or severe RI, including those on dialysis. Methods: The trial is enrolling RRMM pts (N = 80) across 3 cohorts: cohort A (moderate RI, estimated glomerular filtration rate [eGFR] ≥ 30 to < 45 mL/min/1.73 m2, n = 33), cohort B (severe RI without dialysis, eGFR < 30 mL/min/1.73 m2, n = 33), and cohort C (severe RI requiring dialysis, n = 14). Pts must have MM-related RI and have received ≥ 1 prior Tx (including lenalidomide). POM 4 mg is administered on days 1-21 of a 28-day cycle and LoDEX 40 mg/day (20 mg for pts aged > 75 yrs) on days 1, 8, 15, and 22 until progressive disease (PD) or unacceptable toxicity. At the time of submission of this abstract, 17 pts terminated Tx; this abstract focuses on tolerability in these pts. Results: This trial is still recruiting; at the time of data cutoff for this abstract, 39 pts were enrolled. Data are included for 17 pts who discontinued Tx. Of all 39 pts, 12 were assigned to cohort A, 18 to cohort B, and 9 to cohort C. The median age of the total population was 72 yrs (range, 52-86 yrs), with 67.7% being male. The median number of prior lines of therapy was 4.0 (3.5 in cohort A, 5.0 in cohort B, and 3.0 in cohort C). This distribution was similar in the 17 pts who discontinued Tx so far (4, 7, and 6 in cohorts A, B, and C, respectively), with a median age of 72 yrs and 58.8% being male. Reasons for discontinuation of Tx were PD (7 pts), adverse events (AEs; 3 pts), death (5 pts: 2 pts due to PD, 2 pts due to infections, 1 pt due to hyperkalemia), and other reasons (2 pts: 1 pt aged 86 yrs with general health problems, 1 pt with increasing RI). Median Tx duration in these pts was 6.9 weeks in cohort A, 12.6 weeks in cohort B, and 12.9 weeks in cohort C. The dosage of POM was reduced to 3 mg in 3 pts (1 patient in each cohort), in all cases due to an AE (thrombocytopenia in 2 pts, pneumonia in 1 pt). However, no further Tx reductions occurred. The most frequent toxicity of any grade in the pts who discontinued was hematologic (82.4% [14 pts]), notably neutropenia in 58.8% (50% in cohort A, 42.9% in cohort B, 83.3% in cohort C), anemia in 52.9% (50% in cohort A, 28.6% in cohort B, 83.3% in cohort C), and thrombocytopenia in 52.9% (75% in cohort A, 14.3% in cohort B, 83.3% in cohort C). Grade 3/4 neutropenia occurred in 47.1%; grade 3/4 thrombocytopenia occurred in 35.3%. Notably, febrile neutropenia was reported in only 1 pt in cohort A. Granulocyte colony-stimulating factor was used in 52.9% of pts. Non-hematologic AEs were less frequent. Infections occurred in 7 pts (41.2%), all of which were pulmonary infections, with the exception of 1 case of nasopharyngitis. Asthenia (23.5%) and fatigue (23.5%) occurred predominantly in cohort C. No thromboembolic events or secondary primary malignancies have been reported to date. Conclusions: These data suggest that the combination of POM and LoDEX can be safely administered in pts with RI. A starting dose of POM 4 mg can be used throughout all stages of RI, and the side effects seen in this population have been previously reported with POM use (ie, mainly hematologic events and infections). Rates of neutropenia and thrombocytopenia are similar to reports in a non-RI population. Dose modifications should be considered in pts who develop neutropenia and thrombocytopenia; in pts showing signs of infections, dose interruptions may be considered.

Background: The combination of carfilzomib with immunomodulatory drugs (IMiDs) and dexamethasone is active in multiple myeloma (MM). Carfilzomib, thalidomide, and dexamethasone (KTd) has been studied in upfront MM treatment but has not been studied in the setting of relapsed/refractory myeloma (RRMM). The ALLG MM018/ AMN002 is an open-label phase II study of KTd in patients with RRMM. This study was conducted across 16 sites across Australia, New-Zealand, Singapore, South Korea and Taiwan. Method: Patients with RRMM with 1-3 prior lines of treatment were given carfilzomib [K: 20mg/m2 IV cycle 1 days 1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from cycle 1 day 8 onwards], thalidomide (T: 100mg po nocte) and dexamethasone [dex: 40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, T was omitted, and K was given on days 1,2,15,16 and dex days 1,15 every 28-day cycles for a further six cycles. The primary endpoint was PFS. Secondary endpoints were ORR, overall survival, adverse events, and quality of life (QoL). The study had an 80% power to detect a ≥70% PFS at 6.5 months compared to historical ≤50% PFS at 6.5 months expected with Td (Kropff, M. et al. Haematologica 2012), at a significance level of 0.05. Results: This study has completed accrual. Eighty-three patients [median age of 66 years (42-85)] were enrolled with a median follow up of 15.9 (0.9-26) months. ORR rates were 86.4% (≥VGPR 70.2%). Median PFS was 20m (95% CI 15.9-26m). PFS at 6.5 months was 76.2% (95% CI 73.6-84.9%). Median OS has not been reached, and was 75% at 20 months. The most common grade ≥3/4 AEs were peripheral neuropathy (16%), upper respiratory tract infections (12%), dyspnoea (14%), and hypertension (10%). Grade ≥3/4 cardiac AEs occurred in 6%. The median carfilzomib dose that was delivered was 70.7% (32.8-92.6%) of the target dose. Thus far, 41% of patients have completed the intended 18 cycles of treatment. 21% of patients ceased therapy early. The most common reason for early treatment cessation was disease progression (30%) and adverse events (15%). Fifteen patients (18%) have died, 11 were due to MM, two from infection, one from an ischaemic cardiac event, and one from a traffic accident. QoL, as measured by the EQ-5D-5L instrument, remained stable throughout treatment. Conclusion: The ALLG MM018/AMN 002 study has met its primary endpoint. The KTd schedule as outlined in this study is efficacious in patients with RRMM, resulting in a prolonged PFS and a safety profile in line with previous reports for each of carfilzomib and thalidomide. KTd is an active option in jurisdictions where the cost of other IMiDs prohibits regulatory funding. Comparisons of efficacy and adverse events between the Caucasian and Asian populations will be presented at the meeting.

Abstract Background: Carfilzomib lenalidomide and dexamethasone (KRd) is FDA-approved for the treatment relapsed/refractory multiple myeloma (RRMM) based on data from the ASPIRE study (Stewart K et al. NEJM 2015). Thalidomide, a first generation immunomodulatory drug (IMiD) is less costly than lenalidomide and is synergistic in combination with proteasome inhibitors in the treatment of MM. ALLG MM018/ AMN003 is an open label phase II study of carfilzomib thalidomide and dexamethasone (KTd) for patients with RRMM. The primary end point is progression free survival (PFS). Secondary endpoints include overall response rate (ORR), duration of response (DOR), safety and health related quality of life. Method: Eligible patients were those with RRMM who have had 1-3 prior lines of treatment. The KTd regimen consisted of carfilzomib [20mg/m2 IV C1D1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from C1D8 onwards], thalidomide (100mg po nocte) and dexamethasone [40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, thalidomide was omitted and Kd [carfilzomib 56mg/m2 (36/m2 for patients age ≥75 years) on days 1,2,15,16 and dexamethasone 40mg (20mg for patients age ≥75 years) on days 1,15 every 28 days]was continued for a further 6 cycles. Peripheral blood and bone marrow aspirate and trephine for correlative studies were collected from the first 30 patients, at baseline, after cycle 6 and at confirmed disease progression. The aim of the correlative study was to assess for immunological correlates to clinical outcome. Immunological parameters that will be assessed include NK and T cells subsets on peripheral blood via mass cytometry (CyTOF). On the bone marrow trephine, NK cells, T cells, GRP78 expression within CD38 positive plasma cells, PD1 and PDL1 expression will be assessed at the myeloma site and the surrounding microenvironment using OPAL multiplex immunohistochemistry technology. Results: Between March 2017 to June 2018, 56 patients (median age 66 years, range 56-79; 77% Caucasian and 23% Asian) out of the planned 100 were enrolled, with a median follow up of 4.9 (range, 1.0-13.7) months. Response rates in 39 evaluable patients were ≥MR (97%), ≥PR (89%) and ≥VGPR (66%). Median PFS is not reached, and no patients with ≥MR have relapsed. Grade ≥3/4 AEs occurred in 56% of patients, the most common of which were peripheral sensory neuropathy (13%), dyspnoea (13%) and infections (7%). All grade cardiovascular AEs included dyspnoea (27%), cardiac complications (5%), systemic-hypertension (9%) and pulmonary-hypertension (1.9%), however very few were grade ≥3. Three patients have died on study from disease complications, haemorrhage, and primary cardiac ischaemic event. Thus far, we have not found a significant difference in rates or profile of adverse events between the Caucasian versus Asian subgroups of patients. Conclusion: This preliminary analysis demonstrates that the KTd combination is a tolerable regimen for patients with RRMM with a safety profile in line with previous reports for each of carfilzomib and thalidomide. Initial response rates appear very promising and durable with responses up to 13.7 months thus far in some patients. Patient accrual is ongoing.

Abstract Introduction Given the relapsing nature of indolent non-Hodgkin lymphomas (iNHL), the prolonged natural history suggests many patients will undergo multiple lines of therapy over the course of their disease. Combination approaches with rational selection of synergistic mechanisms of action are desirable to improve outcomes and minimize overlapping toxicity. Rituximab and lenalidomide (R2) has resulted in favorable efficacy and manageable toxicity in phase II and III studies (Fowler et al, Lanc Oncol 2014; Fowler et al, ASCO abstract 2018) in untreated iNHL. Ibrutinib, a BTK inhibitor and active B-cell receptor signaling pathway inhibitor, is an attractive agent to build upon R2 given the therapeutic activity in the microenvironment via enhanced T cell activation and function, reduction in inflammatory cytokines, and diminished interaction with macrophages (Niemann et al, Clin Can Res 2015). We hypothesized that the addition of ibrutinib to R2 (IR2) would result in enhanced efficacy; the concern from the Phase I study was the potential for excess grade 3 rash (Ujjani et al, Blood 2016). In an attempt to reduce the incidence of grade 3 rash observed in the phase 1 study, an alteration in the cycle 1 dose of lenalidomide was done to assess the efficacy and safety of IR2 in untreated follicular (FL) and marginal zone lymphoma (MZL) in an open-label phase II, single center study. Methods In this phase II study, adults with untreated stage II, III, or IV FL (grade 1, 2, or 3a) or MZL, who were in need of therapy, received an initial cycle of lenalidomide 15mg/day (days 1-21 of a 28 day cycle), ibrutinib 560mg/day, and 4 weekly doses of rituximab (375mg/m2). For cycles 2-12, patients received 20mg of lenalidomide on days 1-21, 560mg of ibrutinib daily, and rituximab (375mg/m2) on day 1 of each cycle. The primary endpoint was progression-free survival (PFS) at 2 years. Secondary endpoints include: complete response (CR), partial response (PR), overall response (ORR), duration of response (DOR) and overall survival (OS). Results Forty-eight patients with FL (N=38) and MZL (N=10; nodal MZL N=4; splenic ZML N=3; MALT N=3) were enrolled. Median age was 60 years (range 37-81), 67% were male (N=32), 3 (6%) had stage II disease, 12 (25%) stage III, and the remainder had stage IV disease (69%). With a median follow up of 19 months, the estimated 2 year PFS rate was 76% (95% CI: 60-96%). Among FL patients, the ORR according to Lugano criteria was 97%, with a CR rate of 78%. Among MZL patients, the ORR was 80% with a CR rate of 60%. No deaths have been observed to date. Seven (15%) subjects discontinued therapy due to treatment related adverse events (AEs), 3 due to recurrent grade 3 rash, 2 due to pneumonitis (1 grade 2, 1 grade 3), 1 due to pneumonia (grade 3), and 1 due to ventricular arrhythmia (grade 4). The most common grade ≥3 AEs were rash (46%), neutropenia (15%), and diarrhea (13%). The majority of patients with grade 3 rash were managed with interruption in study drugs and antihistamines with successful re-challenge. The most common grade 2 AEs included fatigue (23%), diarrhea (15%), myalgias (17%), rash and edema (each 10%). One patient experienced atrial fibrillation (grade 2) and 1 had an upper GI bleed (grade 3); both successfully resumed treatment without dose reduction. Correlative and minimal residual disease studies are currently underway and will be presented at the meeting. Conclusions Ibrutinib in combination with rituximab and lenalidomide for untreated FL and MZL was associated with promising efficacy. The toxicity profile was manageable. Modification of lenalidomide dose did not significantly impact the incidence of grade 3 or higher rash. Biomarkers are underway to identify patients most likely to benefit from triplet therapy.

Abstract Abstract 301 Background: Pomalidomide (POM) is an IMiD® derived from thalidomide with a modified chemical structure with improved potency in vitro and potential efficacy and safety benefits in vivo. Two phase (Ph) 1b, single-center, ascending dose, open-label studies in pts with relapsed/refractory multiple myeloma (MM; Schey et al, 2004, Streetly et al, 2008) identified maximum tolerated dose (MTD) as 2mg QD or 5mg on alternate days (28 of each 28-day cycle). High response rates of POM alone in heavily pretreated pts were encouraging. To evaluate the MTD, safety and efficacy of POM alone or with Dexamathasone (dex) on a 21/28 day schedule, a Ph 1/2, multicenter, randomized, open-label, 3×3 dose-escalation study was initiated in pts with relapsed/refractory MM after at least 2 prior regimens, including bortezomib and lenalidomide. Methods: The study has a Ph 1 POM MTD (n=32) portion, followed by Ph 2 open-label randomized POM+ dex vs POM alone (192 pts planned). Eligible pts had documented relapsed/refractory MM. All pts received low-dose prophylactic aspirin QD and monitored for venous thromboembolic events (VTE). In Ph 1, POM was given QD on Days 1–21 of 28-day cycle: 4 dose levels of POM (2, 3, 4, 5mg) were studied with option to add dex at 40 mg/wk after 4 cycles for lack of response or progressive disease (PD). Pts enrolled in Ph 1 and discontinued either for intolerance or PD could not be enrolled in Ph 2. Toxicities and responses were assessed using CTCAE v3 and modified European Group for Blood and Marrow Transplantation (EBMT) criteria. Results: Results from Ph 1 of the study are reported with 32 pts enrolled to date. Fifteen pts discontinued therapy and 17 pts are ongoing for both safety and efficacy analyses. Mean age is 66.6 yrs (range 38–84), with median number of prior regimens 7 (range 2–18). MTD has not yet been reached. There were 4 dose reductions due to POM (5mg [2-neutropenia, 1-rash]; 3mg [1-neutropenia]) after 108 completed cycles. Neutropenia and thrombocytopenia were the most common grade 3/4 toxicities, with no dose-dependent increase apparent so far: 12 serious adverse events (SAEs) occurred in 10 pts; drug related events included POM (VTE, syncope, 3rd degree AV block, asthenia, diarrhea, neutropenia, anemia, rash); dex (lung infection with neutropenia); POM + dex (sepsis with pharyngeal abscess). AEs such as somnolence (1) VTE (1) neuropathy (2), and constipation (4) were uncommon. There were 3 deaths on study not attributed to POM; 2 pts died of rapid PD, 1 pt died of gastrointestinal perforation due to amyloidosis. Responses were seen at each dose level (Table 1). In 20/21 (95%) evaluable pts, clinical activity (SD or better) was reported. During treatment with POM alone, overall response rate (ORR; 1 CR, 2 PR, 5 MR) was 38% (8/21), mean duration of response (DOR) was 11.1 (range 4–32) wks, mean time to progression (TTP) was 8.3 (range 2–36) wks. Median completed cycles of POM +/− dex overall was 4 (range 1–12), with 13/21 evaluable pts (62%) having dex added to their regimens at various different cycles (median cycle 3, range 2–9) for PD or lack of response. During treatment with POM+dex, ORR (2 PR, 3 MR) was 38%, mean DOR of 14.2 (range 4–32) wks, and mean TTP of 20 (range 4–52) wks. In addition, there were 9 stable diseases (SD) on POM alone with mean DOR of 7.1 (range 4–16) wks, and 6 SD on POM + dex with mean DOR of 10.7 (range 8–16) wks. In 5/13 pts (38%), responses improved after dex was added (2 PR, 2 MR, 1 SD). Conclusions: These preliminary results indicate that POM alone or in combination with dex is associated with 38% MR or better, while SD was achieved in 43% (POM alone) and 46% (POM + dex), amongst heavily pretreated pts with relapsed/refractory MM. The incidence of SAEs and discontinuations decreased with increased dose of POM with no dose-dependent increase in grade 3/4 hematological toxicities. The MTD has not been reached to date. Overall, these data indicate that POM has an acceptable safety profile and is a clinically active therapeutic option for advanced refractory MM, warranting further investigation in this patient population.

Abstract Abstract 3925 Introduction: CLL patients (pts) who relapse following purine-analog or bendamustine-based treatments have a poor prognosis. These pts have limited therapeutic options and novel agents with alternative mechanisms of action are needed. Several phase 1 and 2 trials in rel/ref CLL showed promising activity with escalating dose regimens of lenalidomide (LEN). In other phase II studies improved clinical responses to lenalidomide appeared to correlate with dose levels > 5mg/day. This phase 2 trial investigates the safety of LEN initiated at 3 different starting doses followed by a step-wise dose escalation as tolerated in rel/ref CLL. Methods: In this ongoing trial, eligible pts with rel/ref CLL who have received ≥ 1 prior treatment regimen containing purine-analog or bendamustine are being enrolled. The objectives of this study are to evaluate primarily the safety and secondarily the efficacy of different LEN dose regimens. Pts are randomized 1:1:1 to receive a double-blinded starting dose of 5 mg, 10 mg, or 15 mg oral LEN on days 1–28 of each 28-day cycle. In all 3 treatment arms, the dose is escalated by 5 mg increments every 28 days to reach a maximum dose of 25 mg/d, depending on tolerability. In instances of poor tolerability, dose reductions also occur in 5 mg steps. Pts are stratified by relapsed versus refractory status to their last purine-analog or bendamustine-based treatment regimen and according to age (< 65 vs ≥ 65 years). Tumor lysis syndrome (TLS) prophylaxis comprises of oral hydration and allopurinol 300 mg/day and is initiated ≥ 3 days prior to starting study drug and for a minimum of the first 3 treatment cycles. A total of 105 pts are planned for enrollment to the study. Per protocol, unblinded interim analyses were conducted by the independent Data Monitoring Committee (DMC) after 18 subjects completed 1 cycle and continue at 13-week intervals. Results: To date, 95 pts are enrolled at a median age of 64 years (range 32–81). Enrolled pts are primarily male (67%) and Caucasian (92%). Cytogenetic data are available for 73 pts; 21% have del(17p), 55% have del(13q), 25% have del(11q), and of 72 patients evaluable for trisomy 12, 11 patients (15%) tested positive. IGVH is unmutated in 77% of 77 evaluable pts and 44% of 84 evaluable pts are ZAP70-positive. Based on the Binet and Rai staging systems 9 (10%), 25 (26%) and 24 (25%) of subjects are stage A, B and C, respectively; 7 (7%), 12 (13%) and 16 (17%) subjects are low, intermediate or high-risk disease, respectively. For 2 (2%) subjects the Binet/Rai staging is currently unknown. Overall, 19 pts (20%) received prior bendamustine-containing treatment and 71 pts (75%) received prior fludarabine-based treatment. The median number of prior therapies was 3 (range 1–10). Most common hematological grade ≥ 3 AEs include neutropenia (62%) and thrombocytopenia (34%). At baseline, 19% of pts presented with grade 1–2 neutropenia. The most common non-hematological ≥ grade 3 AEs include pneumonia (13%), tumor flare (13%), and fatigue (11%). TLS was reported in 3 pts (3%): grade 1, 3, and 4. In total, 8 grade 5 events were reported, 3 of which were suspected to be related to LEN: 2 cases of pneumonia and 1 death for unknown cause. At the time of the cut-off, 59 pts (62%) have discontinued treatment. Most common reasons for treatment discontinuation include disease progression (n = 20) and AEs (n = 20). To date, 47 pts (49%) have dose escalated above their starting dose levels of which 12 patients escalated to the highest dose level (25 mg daily). 18 subjects have had no dose level reduction or escalations and 1 patient is still in the first cycle of the study. Average duration of treatment is 6.5 cycles, and median number of cycles is 4. Efficacy evaluations are completed monthly after 3 months of study drug treatment. At time of the data reporting, 5 pts were on study drug but did not reach the first assessment at cycle. For the 90 pts evaluable for response, the investigator's assessment indicates 2 pts (2%) reached CR, 36 (40%) achieved PR, 33 (37%) patients had SD, and 19 (21%) pts progressed. Conclusion: The independent DMC, as of 14 June, 2012 (N=95), recommended that accrual into all three treatment arms should continue as planned, suggesting all three starting doses were well tolerated. To date, the ORR is 42% and 49% of pts were dose escalated at least once. In this rel/ref CLL population LEN appears active, and completion of accrual will clarify the appropriate dose at which to initiate therapy.

Abstract Background Polycythemia vera (PV) is the most common of the myeloproliferative neoplasms and is characterized by elevated hematocrit requiring phlebotomy, splenomegaly, a variety of symptoms and increased thrombotic risk. Ruxolitinib, a JAK1/JAK2 inhibitor, was well tolerated and achieved rapid and durable clinical responses in a phase 2 study of patients (pts) with PV who were resistant to or intolerant of hydroxyurea (HU). Pts experienced phlebotomy independence, resolution of splenomegaly, and improvements in white blood cell (WBC) counts, platelet (PLT) counts, and disease-related symptoms. Here, we describe the baseline (BL) characteristics and symptom burden of pts in a phase 3 study of ruxolitinib in pts with PV who are resistant to or intolerant of HU. Methods RESPONSE is a randomized (1:1), open-label, phase 3 study (NCT01243944) comparing the efficacy and safety of ruxolitinib with best available therapy (BAT) in pts with PV who are resistant to or intolerant of HU (modified European LeukemiaNet criteria), have splenomegaly, and require phlebotomy for inadequate hematocrit (Hct) control. Fourteen disease-related symptoms were assessed on a scale of 0 (absent) to 10 (worst imaginable) using the modified Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF). Blinded data are presented here. Results BL demographic data are available for the 222 enrolled pts (Table). Apart from HU, other common prior medications for PV included interferons (15%), PLT aggregation inhibitors (10%), alkylating agents (3.6%), alkyl sulfonates (3.2%), pyrimidine analogues (1.8%), and nitrosoureas (1.4%). The majority of pts (54.5%) had 1 phlebotomy within 12 weeks prior to screening; 23.9% had 2 and 17.1% had 3 or more phlebotomies. RESPONSE BL demographics are generally similar in terms of age (60 years vs 57-67); sex (66% male vs 58%-68%); Hct (44% vs 45%-48%); and platelets (419 x 109/L vs 320-429 x 109/L) to other PV studies including trials of givinostat (Finazzi BJH 2013) and AOP2014 (Gisslinger ASH 2012) and the ECLAP-PV (Marchioli JCO 2005) and CYTO-PV studies (Marchioli NEJM 2012). At the time of writing, BL symptom data from the MPN-SAF were available for 164 pts (Table). Pts in this study reported a similar symptom burden as PV pts from a large study of pts with MPNs (Emanuel JCO 2012; N = 1425; PV, n = 538), including similar mean scores for early satiety, abdominal discomfort, concentration problems, night sweats, itching, and tiredness/fatigue. In addition, prior therapy may have adversely affected BL symptom burden, as many of these symptoms (concentration problems, night sweats, fatigue) have been shown to be worsened by the use of conventional therapy to strictly control Hct (< 45%) and cardiovascular risk (Emanuel EHA 2013). BL MPN-SAF symptom data for all 222 pts will be presented. In addition, correlations between BL EORTC QLQ-C30 and MPN-SAF scores will be presented. Summary/Conclusions Demographic and BL symptom data from the RESPONSE study demonstrated that pts with HU refractory or intolerant PV have a significant disease burden that includes a variety of symptoms. These findings are consistent with those of Emanuel (JCO 2012), which showed that pts with PV have a significant symptom burden and a reduced quality of life. Pts with PV in the RESPONSE study are representative of those who have been studied in other clinical trials for the treatment of PV.

Abstract Background: The clinical course of follicular lymphoma (FL) is characterized by a slow progression over years with continuous relapses despite good response to initial treatment. The median overall survival is 10 to more than 15 years. Standard therapy for patients requiring treatment consists of an anti-CD 20 antibody combined with chemotherapy followed by antibody maintenance. With this combination a 1-year-PFS of 93% was seen in the GLSG-2000 trial (Hiddemann et al, Blood 2005). Because of the substantial side effects of chemotherapy such as infections, secondary malignancies and impairment of the stem cell reserve novel "chemotherapy-free" treatment approaches could substantially improve the treatment tolerability in FL. The BTK-inhibitor ibrutinib has demonstrated promising activity in patients with iNHL, CLL and MCL. Anticipating the recent reports on a superior activity of obinutuzumab as compared to rituximab in the GALLIUM trial (Marcus et al., NEJM 2017), the GLSG initiated a phase II study combining ibrutinib and obinutuzumab to explore the efficacy and safety of this "chemotherapy-free" alternative. Methods: ALTERNATIVE is a prospective multicenter single-arm phase 2 study of the combination of ibrutinib and obinutuzumab in 98 patients with previously untreated FL and a high tumor burden (defined by modified GELF criteria) in need of treatment. Induction comprises 6 cycles of obinutuzumab at a dose of 1000 mg by intravenous infusion on days 1, 8, 15 of cycle 1 and on day 1 of cycles 2-6 to be given every 21 days. Ibrutinib is administered orally at a dose of 560 mg once daily throughout all 6 cycles. In patients with at least partial response (defined by Cheson Response Criteria 2007) after the end of induction, maintenance with obinutuzumab (1000mg every 8 weeks) plus ibrutinib (560mg daily) is given for an additional 24 months. In patients remaining MRD positive at 30 months ibrutinib is continued for another 12 months in an extended maintenance setting without obinutuzumab. The primary efficacy endpoint is the rate of investigator-assessed PFS one year after registration. Response rates at end of induction, after one year and after end of maintenance, duration of response, percentage of progression during induction and maintenance, time to treatment failure, overall survival, duration of molecular remission in MRD negative patients and safety are key secondary endpoints. Results: 98 patients with advanced stage FL were included, The median age was 59 years (29-81), 60% were male and 40% had a high risk FLIPI, 90% stage III/IV disease and 10% were stage II with a high tumor burden. Response to in induction was 90% (87/97) with 85% (82/97) PR and 5% (5/97) CR. 5 patients (5%) progressed during induction. Of the 82 patients with PR after end of induction, 8 patients achieved a CR during the first 6 months of maintenance treatment. 95 patients were evaluable for the primary endpoint of 1-year-PFS and 76 patients (80%) remained alive and free of progression at this timepoint. 18 patients progressed in the first year, two of whom died due to progressive disease. One additional death was caused by a non-lymphoma related event. An MRD-marker was found in 65 patients. MRD at the end of induction was evaluable for 63 patients. 44 patients (70%) were MRD negative after induction treatment. Of the 42 patients with follow-up MRD peripheral blood or bone marrow samples, 35 (83%) were MRD negative one year after registration. Therapy was generally well tolerated. Most common adverse events were diarrhea in 30% of patients, rash in 25% and fatigue and nasopharyngitis (common cold) in 23% and 20%, respectively. Concerning hematotoxicity grade 3-4 neutropenia and thrombopenia were seen in 8% and 4% of patients, respectively. Severe (>=grade 3) infectious complications were rare (6% pneumonia/bronchitis, 2% sepsis, 7% other infections). Conclusions: The chemotherapy - free combination of ibrutinib and obinutuzumab showed high anti-lymyphoma activity with high overall response rates and a high proportion of MRD negativity at one year. While the combination of ibrutinib and obinutuzumab was associated with a low toxicity profile, the combination was inferior to the published results of conventional immunochemotherapies in terms of the primary efficacy endpoint (1-year-PFS). Further evaluations might demonstrate whether subgroups exist which particularly benefit clinically from this low toxicity regime. Figure Figure.

Background: Cutaneous T cell lymphoma is incurable with current therapies and there is an urgent need for more effective therapies. BNZ-1 is a pegylated peptide antagonist that binds to the common γc signaling receptor for the cytokines IL-2, IL-9 and IL-15. These cytokines, particularly IL-2 and IL-15, have been implicated in the pathogenesis of CTCL through activation of JAK/Stat signaling pathways, Therefore, we hypothesized that inhibition of the IL-2 and IL-15 signaling pathways in CTCL will induce antitumor activity in patients with CTCL. Methods: A multicenter, open-label Phase 1 study is ongoing to characterize the safety and tolerability of BNZ-1 (NCT03239392). Patients with a diagnosis of mycosis fungoides (MF) of any stage or Sézary syndrome (SS) are eligible for this trial. Pts are enrolled in sequential dose cohorts of 0.5 mg/kg, 1mg/kg, 2 mg/kg, and 4 mg/kg to receive intravenous dose of BNZ-1 to characterize safety, pharmacokinetics, pharmacodynamics, and evidence of antitumor activity. Infusions are administered weekly for four doses to evaluate for safety. Thereafter, patients are enrolled on an extension phase for 3 months of weekly dosing of BNZ-1. If patient attain a response, they are eligible for a long-term extension arm, as approved by the FDA. Blood samples are collected to assess the impact of BNZ-1 on the anti-tumor response. Results: pts with MF/SS (11 M/5F, median age 61 years, range 32-89) have been enrolled. Clinical stages include IB (n=6), IIA (n=1), IIB (n=6), IVA1 (n=2), IVB (n=1). Patients were previously treated with a median of 2 ( 1-5) topical therapies and 3 (1-11) systemic therapies. Single and sequential doses of weekly 1 mg, 2 mg, or 4 mg BNZ-1 infusions have been well tolerated. The most frequently reported adverse events were pruritus (n=9), fatigue (n=5) and dry skin (n=3). All treatment-related AEs were Grade 1 or 2 in severity. No SAEs or dose limiting toxicity have been observed to date. Notably reductions in mSWATs and CAILs was noted even in patients with advanced stage disease and/or with features of large cell transformation and folliculotropic subtype. Flow cytometry of peripheral blood at baseline and during treatment indicated activation of anti-lymphoma immune responses associated with the downregulatio of PD1. Concommittantly, excess expression of cytotoxic granules (perforin & Granzyme B) has been downregulated, suggesting the silencing of inflammatory T-cell responses. Conclusions: These preliminary Phase 1 results suggest that pegylated BNZ-1 is well-tolerated and inhibition of IL-2 and IL-15 leads to clinical improvement in patients with CTCL. Evidence for the rejuvenation of anti-lymphoma immunity and a decreasing inflammatory responses was seen in cases showing clinical response consistent with our hypothesis. An expansion cohort in CTCL is currently underway to validate these promising early results.

Abstract Abstract 302 Background: Carfilzomib (CFZ) is a proteasome inhibitor with unique target selectivity and an irreversible binding mechanism that results in sustained proteasome inhibition. In preclinical studies, CFZ lacks non-proteasome off-target activities associated with bortezomib (BTZ) (Kapur et al, Blood 2008). This may account for observed differences in tolerability with CFZ (e.g. minimal neuropathy and myelosuppression), permitting consecutive day dosing and treatment over an extended period of time. We previously observed higher response rates in multiple myeloma (MM) patients without prior BTZ exposure (BTZ-naïve) compared to those with relapsed disease following BTZ therapy (BTZ-treated). Here we present updated data on the BTZ-naïve cohort from PX-171-004, an ongoing Phase 2 study of single-agent CFZ in MM patients with relapsed or refractory disease following 1–3 prior therapies. Methods: Patients with relapsed or refractory (e.g, < 25% response or disease progression during last treatment) MM were enrolled and stratified into two cohorts: BTZ-naïve and BTZ-treated. CFZ 20 mg/m2 IV was administered on Days 1, 2, 8, 9, 15 and 16 every 28 days, for up to 12 cycles. The primary endpoint was Overall Response Rate [≥ Partial Response (PR)] per International Uniform Response Criteria for Multiple Myeloma. Secondary endpoints included Clinical Benefit Response [CBR = ORR + Minor Reponse (MR)] and safety. Results: Fifty-seven BTZ-naive patients have been enrolled and 56 subjects have received at least one dose of CFZ. Prior therapies included alkylators (81%), stem cell transplant (SCT) (77%), thalidomide (THAL) (67%), lenalidomide (LEN) (42%), and anthracyclines (23%). Ten (18%) patients had received both LEN and THAL and 18 (32%) patients were refractory to their most recent regimen prior to study entry. At baseline, 30 (53%) patients had an ECOG score ≥ 1, 21 (37%) had neuropathy Grade ≥ 1, 12 (21%) had impaired renal function (CrCl < 60 mL/min) and 10 (18%) had diabetes. The mean time from diagnosis was 4 years (range 0.7–24). To date, the mean number of CFZ doses administered was 29.2 (∼5 four-week cycles; range 2–72 doses, 1–12 cycles). Fifty-one patients initiated therapy and were evaluable for response per protocol. The ORR was 45% (23/51 patients) and included 1 CR, 4 VGPR and 18 PR. An additional 9 (18%) patients had MR and 10 (20%) had stable disease (SD) for ≥ 6 weeks. The most common (>25%) adverse events (AEs) were fatigue (59%), nausea (41%), dyspnea (36%), and anemia (29%), and were primarily ≤ Grade 2. Grade 3/4 AEs occurring in ≥ 5% of patients were thrombocytopenia (9%), fatigue (9%), neutropenia (7%), lymphopenia (7%), anemia (5%), pneumonia (5%) and hyperglycemia (5%). One (1.7%) patient had febrile neutropenia. Dose modifications were rarely required. Peripheral neuropathy (PN) of any grade was infrequent (7 patients, 12%) with a single case of Grade 3 PN (2%) in a pt with a history of THAL-induced PN that lasted 41 days. The CFZ dose was reduced and the event resolved to Grade 1 while on CFZ and prior to study discontinuation. Of the12 patients with impaired renal function at baseline, none required dose modifications due to renal AE. Overall, 5 patients have completed the full 12-cycle protocol and another 5 (9%) have completed ≥ 9 cycles; 17 patients (30%) are continuing on study. Conclusions: The 45% ORR (CBR 63%) is noteworthy for a single-agent regimen in patients with tumor progression despite therapy with novel combinations. CFZ can be safely administered to patients with significant comorbidities (e.g. peripheral neuropathy, leukopenia, renal dysfunction, diabetes) when other anti-myeloma agents may not be well tolerated. Enrollment to PX-171-004 is continuing and, based on the safety profile, subjects are now permitted to dose escalate to 27 mg/m2. Disclosures: Wang: Proteolix: Honoraria, Research Funding.

Abstract Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of lymphomas in which only ~25% of patients experience long-term survival with CHOP chemotherapy. Recently several drugs have been approved for this entity including pralatrexate (P), romidepsin (R), and belinostat which have response rates ranging from 26%-29% as single agents. Based on our demonstration of synergy of P+R in preclinical models of TCL, we initiated a study on the safety and efficacy of P+R in a phase I-II study for relapsed or refractory lymphomas (NCT01947140) and sought to evaluate biological mechanisms of synergy. A 3+3 dose-escalation study started at P 10mg/m2 and R 12mg/m2 with escalation to P 25 mg/m2 and R 14 mg/m2. Patients were treated on 1 of 3 dosing schedules (weekly x 3 Q28D; weekly x 2 Q21D and QOW Q28D). The primary objective was to determine MTD and DLT; the secondary objective included describing ORR (CR+PR). Patients were required to have relapsed lymphoma of any subtype, ECOG PS ≤2, and adequate organ and marrow function. There was no upper limit to the number of prior therapies or transplantation. Twenty-six patients were enrolled and were evaluable for toxicity. Median age was 52 yrs (23-73) and 58% were male. The median number of prior therapies was 3 (range 1-16). Histologies included HL (N=3), B-cell (N=10 of which FL=4) and T-cell (N=13). The median number of cycles completed was 4 (range 1-12). There were 3 DLTs in cohort 4 (P 20mg/m2 & R 12mg/m2given weekly x 2 Q21D) consisting of 2 Grade 3 oral mucositis and 1 Grade 4 sepsis. The QOW Q28D schedule had no mucositis at all dose levels. Patients dosed at the MTD (P 25 mg/m2 & R 12mg/m2 QOW) did not experience any toxicities. The grade 3/4 toxicities reported in >5% of patients were: neutropenia (31%), thrombocytopenia (31%), anemia (23%), oral mucositis (15%), hyponatremia (8%), pneumonia (8%) and sepsis (8%). Twenty-two patients were evaluable for response, 1 patient is currently on therapy. The ORR in the total, non-PTCL and PTCL populations was 59%; 33% (no CR) and 77% respectively. Of the PTCL patients 4/13 (31%) achieved a CR, 6/13 (46%) achieved a PR, and 1 patient had stable disease. The mean duration of response (DOR) for all patients on the study (N=13) was 6.1 months (1.1 - 26.5), for the non-PTCL population (N=3) was 4.8 m (1.1-11) and for the PTCL population (N=10) was 6.55 months (range 1.6 - 26.5 +ongoing). The mean progression free survival (PFS) for all patients on study (N=26) was 4.8 m (.3 - 30.2), for the non-PTCL population (N=13) was 2.8 m (0.3-14.5), and for the PTCL population was 6.13 months (range 1.5 - 30.2 +ongoing). Pharmacokinetic studies were performed for P and R and data for the first 15 patients is presently available for reporting. PK analyses were performed using WinNonLin® to determine Cmax and AUC. Preliminary Cmax results for P 10 mg/m2 and P 15 mg/m2 are 1810+/-1063 ng/mL and 2748+/-995 ng/mL, respectively. Preliminary Cmax results for R 12 mg/m2 and R 14 mg/m2 are 420+/-198 ng/mL and 552+/- 346 ng/mL, respectively. After infusion with P 10 mg/m2 or 15 mg/m2 PK analysis indicate AUC0-24.08h of 3616+/-1543 h*ng/mL and 4104+/-2124 h*ng/mL, respectively. AUC0-28h after treatment with R 12 mg/m2or 14 mg/m2 was 1503+/-1286 h*ng/ml and 2535+/-2560 h*ng/mL. These values are consistent with that observed for both of these drugs in previous studies. Results from the phase I study conclude that the combination of P + R given on the QOW schedule is safe and very well tolerated. These data support the lineage specific activity of the P+R combination, which is currently being expanded to a multicenter Phase II for PTCL. Figure Figure.
