Abstract Background Patient (pt) survival after becoming refractory/intolerant to novel agent treatment (Tx) is short (Kumar 2012). Depth of response has been shown to predict favorable outcomes (Harousseau, 2010). POM is a distinct oral IMiD® immunomodulatory agent with 3 primary activities: direct anti-myeloma activity, stromal cell-support inhibition, and immune modulation (Quach, 2010). POM has been approved by the US FDA for RRMM pts with ≥ 2 prior Tx, including lenalidomide (LEN) and bortezomib (BORT), and progressive disease (PD) on or within 60 days of completion of the last line of Tx. The randomized phase 3 trial MM-003 demonstrated significantly longer progression-free survival (PFS) and overall survival (OS) with an acceptable tolerability profile for POM + LoDEX vs HiDEX in pts with RRMM (San Miguel, EHA 2013). Methods Pts must have been refractory to last prior Tx (PD during Tx or within 60 days) and exhausted BORT and LEN after ≥ 2 consecutive cycles of each (alone or in combination). Pts were randomized 2:1 to receive 28-day cycles of POM 4 mg D1-21 + DEX 40 mg (20 mg for pts aged > 75 y) weekly or DEX 40 mg (20 mg for pts aged > 75 y) D1-4, 9-12, and 17-20. HiDEX was chosen as the comparator to isolate the effects of POM as at the time of trial design it was the standard salvage Tx for heavily pretreated pts. Tx continued until PD or unacceptable toxicity. The primary endpoint was PFS. Secondary endpoints included OS, time to progression (TTP), overall response rate (ORR; ≥ partial response [PR]), and safety. The current analysis describes pt outcomes by prior Tx history and depth of response. Results 302 pts were randomized to POM + LoDEX and 153 pts to HiDEX. Pt characteristics were well balanced between Tx arms. The median number of prior Tx was 5 (range, 2-17). Most pts (75%) were refractory to both BORT and LEN. POM + LoDEX significantly prolonged PFS vs HiDEX regardless of type or number of prior Tx (Table). OS favored POM + LoDEX for all subgroups analyzed. Importantly, significant OS benefits were observed in pts with ≤ 3 prior Tx and in pts who were refractory to LEN as last prior Tx. The ORR was consistently and significantly higher for POM + LoDEX vs HiDEX. The TTP for POM + LoDEX pts was similar in this trial vs that seen with their last prior LEN-based line of Tx (4.8 vs 6.2 months; P =.11). Additionally, LEN as the last prior Tx did not negatively impact PFS, OS, or ORR when compared with the intent-to-treat (ITT) population. In the POM + LoDEX arm, a total of 17 pts (6%) achieved a very good partial response or better, and 78 pts (26%) achieved PR as best response. Baseline characteristics were generally similar regardless of the degree of M-protein reduction. Analyses of the correlation between M-protein reduction and PFS and OS are ongoing and will be presented at the meeting. Conclusions In this heavily pretreated population, POM + LoDEX provided consistent efficacy regardless of number of prior Tx or prior Tx type. Significant OS benefits were observed for pts who received POM + LoDEX earlier in Tx and immediately following the development of LEN-refractory disease. Importantly, LEN as last prior Tx did not impact response, PFS, or OS vs the overall ITT population. POM + LoDEX should be considered a standard Tx option in RRMM pts.

Abstract Background The combination of the immunomodulatory drug lenalidomide (LEN) with the proteasome inhibitor bortezomib (BORT) and dexamethasone (DEX) has demonstrated substantial preclinical and clinical activity in patients with MM (Richardson PG, et al. Blood. 2010; Kumar S, et al. Blood. 2012). Pomalidomide (POM), a distinct immunomodulatory agent, has been approved by the US FDA for patients with RRMM with ≥ 2 prior therapies, including LEN and BORT, and progressive disease (PD) on or within 60 days of completion of the last line of treatment (Tx). POM with low-dose DEX (LoDEX) has demonstrated efficacy in patients with RRMM treated with prior LEN and BORT (San Miguel, EHA 2013; Leleu X, et al. Blood. 2013; Richardson PG, et al. Blood 2013; Lacy MQ, et al. Blood. 2011). MM-005 was designed to identify the optimal dose of POM-BORT-DEX (PVD) combination Tx for a phase 3 trial comparing PVD vs BORT + LoDEX (VD) in patients with RRMM (MM-007). Methods Eligible patients had RRMM with 1-4 prior lines of Tx including ≥ 2 consecutive cycles of LEN and a proteasome inhibitor. Patients must have been refractory to LEN (PD during or within 60 days of LEN Tx) but not refractory to BORT (at 1.3 mg/m2 twice weekly). The maximum tolerated dose (MTD) was determined using a 3 + 3 design in 5 cohorts. Each cohort received 21-day cycles of POM (1-4 mg/day on days 1-14); intravenous BORT (1-1.3 mg/m2 on days 1, 4, 8, and 11); and LoDEX (20 mg/day on days 1-2, 4-5, 8-9, and 11-12; patients aged > 75 years received 10 mg/day on days 1-2, 4-5, 8-9, 11-12). The study protocol was revised to include a 6-patient cohort receiving subcutaneous BORT. Thromboprophylaxis was given to all patients as either aspirin or low-molecular-weight heparin. Once established, an expansion cohort was enrolled at the MTD. Tx was continued until PD or unacceptable toxicity. Dose-limiting toxicities (DLTs) were assessed during cycle 1. MTD was the primary endpoint; secondary endpoints included safety, overall response rate (ORR; ≥ partial response), duration of response, and time to response (TTR). Results A total of 28 patients across all Tx cohorts is planned. As of April 2013, 22 patients have been enrolled, 21 patients were evaluable for baseline characteristics and safety, and 20 patients were evaluable for response. The median age was 57 years (range, 36-75 years). The median number of prior Tx lines was 2 (range, 1-4). All patients were refractory to LEN and had received prior BORT. 67% of patients had progressed on LEN as their last prior Tx and an additional 2 patients never responded to LEN. At the time of analysis, 14 of 22 (64%) patients remain on study. The primary reason for discontinuation was PD (27%). No DLTs have been observed during cycle 1 at any dose level; thus, the MTD/maximum planned PVD dose is POM 4 mg (days 1-14); intravenous BORT 1.3 mg/m2 (days 1, 4, 8, and 11 for cycles 1-8; days 1 and 8 for cycles 9+); and LoDEX 20 mg/day (days 1-2, 4-5, 8-9, and 11-12 for cycles 1-8; days 1-2, 8-9 for cycles 9+). The most common grade 3/4 adverse events (AEs) were neutropenia (29%) and thrombocytopenia (19%). With thromboprophylaxis, no deep vein thrombosis was observed. Despite 62% of patients having a history of peripheral neuropathy (PN) at baseline, only 29% developed grade 1 and 14% developed grade 2 PN; no grade 3/4 PN was observed. Only 1 patient has discontinued due to AE (Tx-unrelated metastatic pancreatic cancer). Thus far, the ORR is 75% (15 of 20 evaluable), 30% achieving very good partial response (VGPR) or better (including 1 patient in stringent complete response). Responses were rapid (median TTR of 1 cycle [range 1-3]). Many responses are ongoing and may improve with longer follow-up. Responses were also observed in patients with adverse cytogenetics. Updated and pharmacokinetic data on all 28 patients are planned for presentation at the meeting. Conclusions PVD was generally well tolerated in this population of LEN-refractory and BORT-exposed patients with RRMM, with no DLTs and no discontinuations due to Tx-related AEs to date. PVD had promising activity in this population of LEN-refractory and BORT-exposed RRMM pts with an ORR of 75% and 30% ≥ VGPR. The maximum planned dose of POM 4 mg/day on days 1-14; BORT 1.3 mg/m2 on days 1, 4, 8, and 11; and LoDEX 20 mg on days 1-2, 4-5, 8-9, and 11-12 (21-day cycles) has been incorporated into the ongoing MM-007 randomized, prospective phase 3 trial comparing PVD with VD in patients with RRMM (N = 782).

Abstract Introduction: Panobinostat is a potent pan-deacetylase inhibitor (pan-DACi) that targets key aberrations in multiple myeloma (MM) cell biology, including epigenetics and protein metabolism. In the phase 3 clinical trial PANORAMA 1, panobinostat in combination with bortezomib and dexamethasone (PAN-BTZ-Dex) led to a statistically significant and clinically relevant increase in progression-free survival of approximately 4 months compared with that with placebo plus bortezomib and dexamethasone (Pbo-BTZ-Dex). Further analyses of patient outcomes by prior treatment demonstrated that the magnitude of PFS benefit was greatest among patients who received at least 2 prior regimens, including bortezomib and an immunomodulatory drug (IMiD; PAN-BTZ-Dex [n = 73]: 12.5 months [95% CI, 7.3-14.0 months]; Pbo-BTZ-Dex [n = 74]: 4.7 months (95% CI, 3.7-6.1 mo; HR 0.47 [95% CI, 0.32-0.72]). These data supported the regulatory approvals of PAN-BTZ-Dex for the treatment of patients with multiple myeloma who received at least 2 prior regimens, including bortezomib and an IMiD. Here we present the final analysis of overall survival (OS) for the entire patient population and among patients who received at least 2 prior regimens, including bortezomib and an IMiD. Methods: The study design for the PANORAMA 1 trial was described previously (San-Miguel. Lancet Oncol. 2014;15:1195-206). The key secondary endpoint was OS. As of June 29, 2015, the 415 events required to conduct the final analysis of OS had been observed. Kaplan-Meier estimation was utilized for OS analyses for the entire population (N = 768), the pre-specified subgroup of patients who received prior bortezomib and IMiD (n = 193), and patients who received at least 2 prior regimens including bortezomib and an IMiD (n = 147). Results: The median OS of patients who received PAN-BTZ-Dex in the overall population was 40.3 months (95% CI, 35.0-44.8 months) vs 35.8 months (95% CI, 29.0-40.6 months) for the Pbo-BTZ-Dex arm with HR 0.94 [95% CI, 0.78-1.14], P = .5435 (Fig 1A). The percentage of patients in each arm who received post-study therapy was 37.7% in the PAN-BTZ-Dex arm and 48.8% in the Pbo-BTZ-Dex arm. The median OS of patients who received at least 2 prior lines, including bortezomib and an IMiD, was 25.5 months (95% CI, 19.6-34.3 months) in the PAN-BTZ-Dex arm vs 19.5 months (95% CI, 14.1-32.5 months) in the Pbo-BTZ-Dex arm (Fig. 1B). The proportion of patients in this subgroup who received post-study therapy was 35.6% in the PAN-BTZ-Dex arm and 66.2% in the Pbo-BTZ-Dex arm. Conclusion: For the overall PANORAMA 1 study population, patients in the PAN-BTZ-Dex arm demonstrated an increase in median OS of 4.5 months vs patients in the Pbo-BTZ-Dex arm, but this result was not statistically significant (P = .5435). Median OS was also slightly longer for the PAN-BTZ-Dex arm among the more heavily pretreated subgroup of patients who received at least 2 prior regimens, including bortezomib and an IMiD. A higher percentage of patients on the Pbo-BTZ-Dex arm received post-study therapy vs the PAN-BTZ-Dex arm, which may have confounded the OS results. In summary, PAN-BTZ-Dex demonstrates statistically significant increases in PFS vs Pbo-BTZ-Dex in patients with relapsed or relapsed and refractory MM; however, this did not translate to a statistically significant increase in OS. Future trials will plan to focus on further optimization of dose and schedule of panobinostat and bortezomib to improve outcome, as well as novel combinations with other agents, including IMiDs and next-generation proteasome inhibitors.

Introduction Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS), is a rare and potentially life-threatening complication of hematopoietic stem cell transplantation (HSCT). Severe cases, historically defined by multi-organ dysfunction (MOD), may be associated with mortality rates of >80%. There is no FDA-approved treatment for VOD/SOS. Defibrotide (DF) has a proposed mechanism of action that includes stabilization of endothelial cells and restoration of thrombo-fibrinolytic balance. Earlier analyses of a pivotal phase 3 trial of DF in VOD/SOS plus MOD (Richardson et al. Blood. 2009;114:Abstract 654) underpinned approval of DF in the EU to treat severe hepatic VOD/SOS after HSCT. Additional data were obtained at the request of US health authorities. Here we present the final analysis: day +100 survival (primary endpoint) and complete response (CR; secondary). Methods This was a multicenter, open-label, phase 3 historical control (HC) study assessing DF. Eligible patients met Baltimore VOD/SOS criteria (total bilirubin ≥2.0 mg/dL with ≥2 of: hepatomegaly, ascites, or 5% weight gain) by day +21 post-HSCT, plus MOD (renal [trebling of creatinine levels, reduced creatinine clearance, or dialysis] and/or pulmonary [oxygen saturation ≤90%, need for oxygen supplementation/ventilator dependence]) by day +28 post-HSCT. Exclusion criteria included severe graft-versus-host disease (GvHD) of liver or gut, clinically significant bleeding, or need for ≥2 pressors. HC patients were reviewed for inclusion/exclusion criteria in a sequential review of medical charts starting 6 months prior to use of DF at each site; a blinded medical review committee made the final determination of HCs unequivocally meeting criteria for VOD/SOS with MOD. DF dose was 25 mg/kg/d in 4 divided 2-hour IV infusions q6h; recommended treatment duration was ≥21 days. Primary endpoint was day +100 survival. CR by day +100 was a secondary endpoint. Treatment difference in survival and CR rates and their 95% confidence intervals were estimated using propensity-stratified and weighted (Koch-adjusted) estimates of differences in proportions that account for baseline prognostic factors of survival (ie, ventilator and/or dialysis dependency at entry, age ≤/>16 years, transplant type, and prior HSCT). Analyses included patients treated with DF and HCs. Results There were 102 patients in the DF group and 32 cases selected as HCs. Baseline characteristics were similar in the DF and HC groups: mean age (26 and 25 years; 43% and 44% ≤16 years), allogeneic graft (88% and 84%), prior HSCT (13% and 9%), ventilator- and/or dialysis-dependent at study entry (33% and 22%), myeloablative conditioning (87% and 94%), and the most common underlying diseases (acute leukemias: 45% and 47%), respectively. In the DF-treated group, common GvHD medications included tacrolimus (49%), methotrexate (41%), and cyclosporine (38%); in the HC group, common medications were cyclosporine (72%) and methotrexate (63%). Survival at day +100 in the DF and HC groups was 38% and 25%, respectively. The propensity-stratified difference in survival was 23.0% (95.1% CI, 5.2-40.8, P = .0109). Respective observed CR rates by day +100 were 25.5% and 12.5%, and the propensity-stratified difference in CR was 19.0% (95.1% CI, 3.5-34.6, P = .0160). Comparing the earlier EU and final analyses, the survival rates at day +100 in each group did not vary; however, the propensity adjusted final analysis provided a different level of statistical significance. Day +100 CR rates in the original analysis were slightly lower in both arms at 24% and 9% due to increased data capture to investigate CR; the P value was essentially unchanged. For the DF group, 45% had an adverse event (AE) at least possibly related to study drug, and 21% had a serious AE at least possibly related to study drug. In this very sick population, percentages of patients with ≥1 AE leading to death were similar between DF and HC patients (64% and 69%), as were hemorrhagic AEs (64%, 75%) and hypotension (39%, 50%). Conclusions Based on observed study data and using a propensity-adjusted rate difference estimator, patients treated with DF had a 23% reduction in risk of death by day +100 and 19% improvement in CR rate. Overall incidence of hemorrhage and fatal AEs were similar between groups with AEs consistent with those expected in this critically ill population. Support: Jazz Pharmaceuticals.

Background: Current treatment options for red blood cell (RBC) transfusion-dependent (TD) patients with lower risk (LR) myelodysplastic syndromes (MDS) relapsed after or refractory to erythropoiesis-stimulating agents (ESAs) have limited efficacy and durability; new approaches are needed. Imetelstat is a 13-mer lipid-conjugated oligonucleotide that targets the RNA template of human telomerase and is a competitive inhibitor of telomerase enzymatic activity (Asai et al, Cancer Res 2003; Herbert et al, Oncogene 2005). Preclinical, in vivo xenograft models (Dikmen et al, Cancer Res 2005; Hochreiter et al, Clin Cancer Res 2006) and preliminary clinical data from a pilot study conducted at Mayo Clinic (Tefferi et al, Blood Cancer Journal 2016) supported initiation of a study in TD LR MDS patients. A Phase 2 study of imetelstat, IMerge, demonstrated an 8-week RBC transfusion independence (RBC-TI) rate of 42%, 24-week RBC-TI rate of 29%, and 68% erythroid hematologic improvement (HI-E) rate in 38 heavily TD patients (median prior RBC transfusion burden 8 units / 8 weeks over the 16 weeks pre-study period) with LR MDS. Responses were durable with median duration of 8-week RBC-TI of 85.9 weeks by Kaplan Meier estimates (range 8.0-140.9) (Steensma ASH 2018, Fenaux EHA 2019). These Phase 2 results provided further evidence of potential clinical benefit of imetelstat treatment in TD LR MDS, and supported initiation of a Phase 3 trial. Methods: IMerge is two-part, Phase 2/3 study (ClinicalTrials.gov: NCT02598661). The Phase 2 portion of the study described above is closed for enrollment. The Phase 3 portion of the study is open for enrollment of adult patients with International Prognostic Scoring System (IPSS) low or intermediate-1 risk, non-del(5q) MDS, who are TD, are relapsed after or refractory to ESAs, and have not received treatment with lenalidomide or hypomethylating agents. The study is a randomized (2:1) double-blind, placebo-controlled trial to compare efficacy of imetelstat vs. placebo that will enroll approximately 170 patients and will be conducted at approximately 90 centers in North America, Europe, Asia and Middle East. Imetelstat will be administered as 2-hour IV infusion every 4 weeks at 7.5 mg/kg. The primary endpoint of the study is to assess the rate of RBC-TI lasting ≥8 weeks. Secondary endpoints include safety, rate of RBC-TI ≥24 weeks, time to RBC-TI start, RBC-TI duration, rate of HI-E, the amount and relative change in RBC transfusions, rate of CR or PR, overall survival, progression of MDS, pharmacokinetics and effect of treatment on quality of life. Biomarkers relevant to the mechanism of action of imetelstat will be assessed to demonstrate target inhibition and their association with clinical responses. Cytogenetics and mutation analyses will be performed to evaluate the impact of imetelstat on reduction/depletion of malignant clones leading to disease modification.

Abstract Marizomib (MRZ) is a novel, irreversible, pan subunit proteasome inhibitor (PI) with preclinical evidence demonstrating in vitro and in vivo activity in multiple myeloma (MM). This study was designed to evaluate the safety and antimyeloma activity of pomalidomide (POM), MRZ and low dose dexamethasone (Lo-DEX) (PMD) in patients with relapsed and refractory multiple myeloma (RRMM). Thirty-eight heavily pretreated patients with RRMM were enrolled [dose-escalation cohort (n=14); recommended Phase 2 dose (RP2D) cohort (n=24)]. IV MRZ (0.3 to 0.5 mg/m2) was administered on Days (D) 1, 4, 8, 11; POM (3 or 4 mg) on D1 through 21; and Lo-DEX (5 or 10 mg) on D1, 2, 4, 5, 8, 9, 11, 12, 15, 16, 22, 23 of every 28-D cycle. Patients received a median of 4 (range 1-9) prior lines of therapy; 100% received prior lenalidomide (LEN) and bortezomib (BTZ), 34% carfilzomib (CFZ), and 50% thalidomide. 53% of patients were refractory to both LEN and BTZ and 21% were refractory to LEN, BTZ, and CFZ. There were no dose limiting toxicities during the study. The most common study treatment related ≥Grade 3 adverse events (AEs) were neutropenia (11/38 pts: 29%), pneumonia (4/38 pts 11%), anemia (4/38 pts; 11%), thrombocytopenia (4/38 pts; 11%), and febrile neutropenia (2/38 pts; 5%), with two grade 4 AEs (neutropenia related to POM and viral infection related to DEX), and one grade 5 AE (cardio-respiratory arrest from a suspected PE related to POM). Overall, MRZ was well tolerated, did not add to the incidence or severity of POM/Lo-DEX AEs and the regimen may have fewer hematological and infectious AEs compared to that observed with POM/Lo-DEX. MRZ pharmacokinetic analysis revealed that it was rapidly cleared with a short T1/2 (6.2-11mins) and a large volume of distribution (41-86L) suggesting extensive tissue distribution. Pharmacodynamic analysis demonstrated rapid and robust inhibition of chymotrypsin-like activity in both packed whole blood (PWB) and peripheral blood mononuclear cells (PMBCs), reflecting the irreversible binding nature of MRZ. Evolving inhibition of trypsin-like and caspase-like proteasome activity was also observed in PWB and PBMC with continued dosing. The overall response rate (ORR) and clinical benefit rate (CBR) for the 36 response evaluable patients was 53% (19/36) and 64% (23/36), respectively (Table 1). Subpopulation analysis demonstrated an ORR of 50% (5/10) in high risk cytogenetic patients, 56% (10/18) in LEN/BTZ refractory patients, 71% (5/7) in LEN/BTZ/CFZ refractory patients and 80% (8/10) in CFZ refractory patients. These data compare favorably against POM/Lo-Dex with a near doubling of ORR in both the total patient population and the double refractory patients. Substantial activity in high-risk patients that are triple refractory and in patients that are refractory to CFZ in prior last regimen was observed. MRZ activity in RRMM patients exposed and/or refractory to multiple PIs is likely a consequence of its unique pan proteasome subunit inhibitory actions. In conclusion, MRZ in combination with POM and Lo-DEX was well tolerated and demonstrated promising activity in heavily pretreated, high-risk RRMM patients. Table 1 Table 1.

Background: Myelofibrosis (MF) is a life-limiting condition with severe morbidity in advanced stages. Patients with MF and severe thrombocytopenia (platelet counts <50,000/mL) have a particularly poor prognosis, with more frequent anemia and leukopenia, higher rates of hemorrhagic and thrombotic complications, and worse overall survival (~15 months) compared to the overall MF population (Scotch AH, et al, Leuk Res. 2017; Masarova L, et al, Eur J Haematol. 2018). Moreover, effective treatment options are limited in this high-risk population as the currently approved JAK inhibitor, ruxolitinib (RUX), is associated with treatment-related thrombocytopenia and often requires dose reductions for patients with platelet counts <100,000/mL, with reduced efficacy compared to patients able to tolerate higher doses. Further, there is no approved dose of RUX for patients with platelet counts <50,000/mL, and NCCN guidelines encourage physicians to consider clinical trials for such patients given the lack of approved therapies. Pacritinib (PAC) is an oral JAK2/IRAK1 inhibitor that has demonstrated clinical activity in MF patients in two prior Phase 3 studies (PERSIST-1, PERSIST-2) as well as a Phase 2 dose-finding study (PAC203), including patients with severe thrombocytopenia. The PACIFICA trial has been designed to evaluate the efficacy and safety of PAC 200 mg BID vs. physician's choice (P/C) therapy in patients with MF and severe thrombocytopenia. Study Design and Methods: PACIFICA is a randomized, controlled Phase 3 trial of PAC vs. P/C in adult patients with primary or secondary MF who are not candidates for stem cell transplant, with DIPSS intermediate- or high-risk disease, ECOG PS ≤2, and platelet counts <50,000/mL, who have had up to 90 days of prior treatment with a JAK2 inhibitor or are JAK2 inhibitor-naïve. Additional exclusion criteria exist for patients with recent cardiac or hemorrhagic events, ejection fraction <50%, QTc >450 msec, or use of medications that increase the risk of hemorrhage or QT prolongation. On the PAC arm, patients receive continuous PAC 200mg BID. On the P/C arm, one of the following agents is selected prior to randomization: low-dose ruxolitinib (no more than 5 mg BID while platelet counts remain <50,000/mL), thalidomide, lenalidomide, corticosteroids, or hydroxyurea. The primary objective is to compare the efficacy of PAC vs. P/C based on the proportion of patients achieving a ≥35% spleen volume response (SVR) at Week 24. Secondary objectives include comparisons of the proportion of patients achieving a ≥50% reduction in total symptom score (TSS) at Week 24, overall survival, and proportion of patients who self-assess as "very much improved" or "much improved" as measured by the patient global impression of change (PGIC). Tertiary endpoints include alternative methods of evaluating SVR improvement, hematologic improvement (transfusion independence and improvement in anemia and thrombocytopenia), improvement in fatigue as measured by the PROMIS - Fatigue - Short form 7a, and changes in mutated allelic burden and gene expression (including correlation with response data). The study will enroll ~180 patients in a 2:1 ratio (PAC to P/C), which will have >80% power to achieve the primary endpoint. Enrollment is anticipated to begin in Q3 2019, as PACIFICA is expected to open as an amendment to the Phase 2 PAC203 study (NCT03165734) in select sites.

Abstract Background Idelalisib (IDELA) is a first-in-class, selective, oral inhibitor of PI3Kδ that reduces proliferation, enhances apoptosis, and inhibits homing and retention of malignant B cells in lymphoid tissues. Phase 1 trials demonstrated that IDELA is highly active as a single agent or in combination with rituximab (R) in heavily pretreated patients (pts) with CLL. Pts in these trials experienced reductions in disease-associated chemokines, improvement of organomegaly and cytopenias, profound reductions in lymphadenopathy, and durable clinical benefit with an acceptable safety profile (Brown 2013; Barrientos 2013). Patients with early progression and significant co-morbidities have limited treatment options; single-agent rituximab is an option in these pts (NCCN 2013; Zelenetz 2013). Methods This Phase 3 study evaluated the efficacy and safety of IDELA + R vs placebo + R in pts with previously treated CLL. Eligibility criteria included the need for treatment per IWCLL guidelines, measurable lymphadenopathy, and CLL progression <24 mos since the completion of last therapy. Pts were considered unfit to receive cytotoxic therapy because of comorbidities (defined as a Cumulative Illness Rating Score [CIRS] > 6), renal dysfunction, or cytopenias due to poor marrow reserve. All pts received R at 375 mg/m2 [1st dose] and then 500 mg/m2q2 wks x 4, followed by q4 wks x 3 [8 doses total]) and were randomized to Arm A (n=110; IDELA 150 mg BID continuously) or Arm B (n=110; placebo BID continuously). Primary endpoint was progression-free survival (PFS). Response and progression in both arms were assessed by an independent review committee using standard criteria (Hallek 2008; Cheson 2012). Results were reviewed by an external Data Monitoring Committee (DMC). Results Results are from a pre-specified interim analysis after ∼50% of the total number of 119 planned events of CLL progression or death from any cause. Data cutoff was 30 Aug 2013. Pt characteristics (n=220) included a median age of 71 yrs (78% ≥ 65 yrs); CIRS > 6 in 85%; median creatinine clearance of 63.6 mL/min; and presence of anemia (73%), thrombocytopenia (61%), neutropenia (34%). Median time since diagnosis was 8.5 yrs, median number of prior therapies was 3 (range: 1-12), 44% had del(17p)/TP53 mutation, and 84% had unmutated IGHV. PFS in the IDELA + R arm was superior to placebo +R (HR [95% CI] = 0.15 [0.08, 0.28]; p = 3.0 x 1011). Median PFS of pts treated with IDELA + R was not reached and for placebo + R was 5.5 mos. At 24 wks, the PFS rate for IDELA +R was 93% compared to 46% for placebo + R. PFS strongly favored IDELA + R in all subgroups, including those with del(17p)/TP53 or unmutated IGHV. Pts treated with IDELA + R and with ≥1 post-baseline assessment also had a superior overall response rate (ORR) relative to those in the control arm (81% vs. 13%; odds ratio 29.9; p = 3.0 x 1019) and a higher lymph node response (LNR) rate (93% vs. 4%; odds ratio 264.5; p = 1.3 x 10-30). Relative to the control group, pts treated with IDELA +R also had a significant improvement in overall survival (OS): HR (95% CI) = 0.28 (0.09, 0.86), p = 0.018. Adverse events (AEs) occurring in ≥20% of pts (any Gr/Gr ≥3) by arm were: pyrexia (IDELA + R 29%/3%; placebo + R 16%/1%), fatigue (IDELA + R 24%/3%; placebo + R 27%/2%), nausea (IDELA + R 24%/0%; placebo + R 22%/0%), chills (IDELA + R 22%/2%; placebo + R 16%/0%), infusion-related reactions (IDELA + R 16%/0%; placebo + R 28%/4%), and cough (IDELA + R 15%/0%; placebo + R 25%/2%). Other selected AEs (any Gr/Gr ≥3) included diarrhea (IDELA + R 19%/4%; placebo + R 14%/0%) and rash (IDELA + R 10%/2%; placebo + R 6%/0%). Select lab abnormalities (any Gr/Gr ≥3) included ALT elevation (IDELA + R 31%/6%; placebo + R 9%/1%), anemia (IDELA + R 26%/6%; placebo + R 30%/14%), neutropenia (IDELA + R 55%/34%; placebo + R 49%/22%), and thrombocytopenia (IDELA + R 17%/10%; placebo + R 26%/16%). The most common SAEs were pneumonia (6.4%), pyrexia (6.4%), and febrile neutropenia (4.5%) in IDELA + R, and pneumonia (8.4%), febrile neutropenia (5.6%), and dyspnea (3.7%) in placebo + R. AEs led to study drug discontinuation in 9 pts (8.2%) in IDELA + R and 11 pts (10.3%) in placebo + R. Based on a review of efficacy and safety, the DMC recommended stopping the study early. Conclusions IDELA + R demonstrated statistically significant improvement with acceptable safety over placebo + R in PFS, ORR, LNR and OS in heavily pretreated pts with relapsed CLL, including those with adverse genetic features.

Abstract Background: Treatment options for RBC-TD pts with lower-risk MDS without del(5q) who are unresponsive or refractory to ESAs are very limited. In a previous phase 2 study, MDS-002 (CC-5013-MDS-002), LEN was associated with achievement of RBC-transfusion independence (TI) ≥ 56 days in 26% of pts with IPSS Low/Int-1-risk MDS without del(5q) (Raza et al. Blood 2008;111:86-93). This international phase 3 study (CC-5013-MDS-005) compared the efficacy and safety of LEN versus PBO in RBC-TD pts with IPSS Low/Int-1-risk MDS without del(5q) unresponsive or refractory to ESAs. Methods: This multicenter, randomized, double-blind, parallel-group phase 3 study included RBC-TD pts (≥ 2 units packed RBCs [pRBCs]/28 days in the 112 days immediately prior to randomization) with IPSS Low/Int-1-risk MDS without del(5q), who were unresponsive or refractory to ESAs (RBC-TD despite ESA treatment with adequate dose and duration, or serum erythropoietin [EPO] > 500 mU/mL). Pts were randomized 2:1 to oral LEN 10 mg once daily (5 mg for pts with creatinine clearance 40–60 mL/min) or PBO. Pts with RBC-TI ≥ 56 days or erythroid response by Day 168 continued double-blind treatment until erythroid relapse, disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was RBC-TI ≥ 56 days (defined as absence of any RBC transfusions during any 56 consecutive days). Secondary endpoints included time to RBC-TI, duration of RBC-TI, RBC-TI ≥ 168 days, progression to acute myeloid leukemia (AML; WHO criteria), overall survival (OS), and safety. Baseline bone marrow gene expression profiles were evaluated according to the Ebert signature (PloS Med 2008;5:e35) identified as predictive of LEN response. Clinical trial identifier: CT01029262. Results: The intent-to-treat population comprises 239 pts (LEN, n = 160; PBO, n = 79). Baseline characteristics were comparable across treatment groups; median age 71 years (range 43–87), 67.8% male, and median time from diagnosis 2.6 years (range 0.1–29.6). Pts received a median of 3.0 pRBC units/28 days (range 1.5–9.8) and 83.7% received prior therapy, including ESAs (78.7%). Significantly more LEN pts achieved RBC-TI ≥ 56 days versus PBO (26.9% vs 2.5%; P < 0.001; Table). The majority (90%) of pts with RBC-TI ≥ 56 days responded within 16 weeks of treatment. Median duration of RBC-TI ≥ 56 days was 8.2 months (range 5.2–17.8). Baseline factors significantly associated with achievement of RBC-TI ≥ 56 days with LEN were: prior ESAs (vs no ESAs; P = 0.005), serum EPO ≤ 500 mU/mL (vs > 500 mU/mL; P = 0.015), < 4 pRBC units/28 days (vs ≥ 4 pRBC units/28 days; P = 0.036), and female sex (vs male; P = 0.035). RBC-TI ≥ 168 days was achieved in 17.5% and 0% of pts in the LEN and PBO groups, respectively. The incidence of AML progression (per 100 person-years) was 1.91 (95% CI 0.80–4.59) and 2.46 (95% CI 0.79–7.64) for LEN and PBO pts, respectively, with median follow-up 1.6 and 1.3 years. Death on treatment occurred in 2.5% of pts on either LEN or PBO. The follow-up period was insufficient to permit OS comparison between the 2 groups. Myelosuppression was the main adverse event (AE); in the LEN versus PBO groups, respectively, grade 3–4 neutropenia occurred in 61.9% versus 11.4% of pts, and grade 3–4 thrombocytopenia in 35.6% versus 3.8% of pts. Discontinuations due to AEs were reported in 31.9% LEN and 11.4% PBO pts; among the 51 LEN pts who discontinued due to AEs, 14 discontinuations were due to thrombocytopenia and 8 due to neutropenia. In the subset of pts evaluated for the Ebert signature (n = 203), the predictive power of the signature was not confirmed. Conclusions: LEN therapy was associated with a significant achievement of RBC-TI ≥ 56 days in 26.9% of pts with a median duration of RBC-TI of 8.2 months; 90% of pts responded within 16 weeks of treatment. These data were consistent with response rates seen in the MDS-002 trial. The overall safety profile was consistent with the known safety profile of LEN and these data suggest LEN can be safely and effectively used in this patient population. Figure 1 Figure 1.

Abstract Introduction: CLL pts who qualify for participation in clinical trials are often thought of as a highly selected population. Therefore whether safety and efficacy data from these trials can be generalized to all CLL pts treated in the community setting is unknown. Prospective, observational studies can provide significant insight into pt and disease characteristics as well as practice patterns in different clinical settings. Here we report on baseline demographics and clinical characteristics for 1495 pts who participated in the Connect CLL observational study and were followed prospectively. Methods: Connect®CLL is a non study-specific intervention treatment registry which collects data on the management and outcomes of CLL pts in clinical, academic and community practices in the US. Clinical information was prospectively collected for pts treated in community (n=1312), academic (n=155), or government (n=28) centers in the US between March 2010 – Jan 2014. Pts eligible for treatment or on treatment not more than 2 months were eligible for enrollment. Here we report on the baseline demographics and clinical characteristics of a large CLL cohort stratified by AG, LOT and type of treatment center. Results: In total,1,495 pts were accrued with a median age at enrollment of 69 (range 22–99). Pts were Caucasian (92.2%), African American (6.9%), and male (63.7%). Median duration from diagnosis until initial therapy was 3.7 years (range 0-32). Age of enrolled pts was as follows; 527 pts age <65 years (AG1; 35%); 511 age 65–75 (AG2; 34%); and 457 age ≥75 (AG3; 31%) at the time of enrollment. Eight hundred and ninety-four pts (60%) were treated with front-line therapy (LOT1); 259 pts (17%) treated with second-line therapy (LOT2); and 342 pts (23%) treated beyond second-line therapy (LOT≥3). Patient age: Pt age was associated with significant variation in several clinical variables: Charlson comorbidity index (CCI) score ≥3 (AG 1-3 35/46/52%; p<0.0001), ECOG PS = 0 (AG1-3 60, 48, 33%, p<0.0001) and mean creatinine clearance (CrCl) decreased (AG 1-3 101/74/53 mL/min; p<0.0001). Line of therapy: Differences in baseline characteristics were observed between pts enrolled at LOT1 (previously untreated) and LOT2/≥3 (relapsed). Median age of pts accrued at LOT1 was 68 vs. 70 years for pts enrolled at LOT2/≥3 (p=0.007). ECOG PS = 0 was more frequent at LOT1 (50%) vs. LOT2/≥3 (42%) (p=0.0057). CCI ≥3 at LOT1 was 41% vs 48% at LOT2/≥3 (p=0.0072). When adjusted for differences in age, logistic regression also demonstrated significant differences in performance status (PS=0; p=0.02) and CCI (p=0.03) stratified by LOT. Treating institution: Baseline characteristics also differed by type of treating institution. Median age was 63 vs 70 at academic vs non-academic (p<0.0001). Pts treated at academic sites also had lower CCI (CCI≤2; 72.9% vs 54.2%, academic vs non-academic) and higher median CrCl (86.4 vs 71.4) (p=0.0017). In this registry, only 16% of patients under age 75 had CCI <= 2, CrCl >= 70 mL/min, ECOG 0-1; 18% of patients on LOT1 and 12% of pts on LOT=2 would satisfy these criteria. They represent 36% of eligible pts from academic treating institutions and 13% from community/government centers. Only 20% of patients on LOT1 would satisfy enrollment criteria for CLL8 (FCR vs. FC; Hallek; Lancet 2010) CLL 10 (BR vs FCR; NCT00769522). which did not have enrollment restrictions for age. Conclusions:Baseline characteristics of pts with CLL vary by age, LOT, and type of treatment center. In this large prospective observational study, our data confirms that older pts typically have a worse ECOG PS, more medical comorbidities, more advanced disease when initiating therapy and a lower probability of being treated at an academic medical center. Based on inclusion criteria used for entry in either CLL10 or CLL8, fewer than 20% of pts satisfy age, renal clearance, and fitness profile to be considered suitable for aggressive chemoimmunotherapy in the front line setting. This observation supports the notion that current clinical trial data might not always be applicable to the general CLL population seen in the community and argues for designing clinical trials that are more generalizable to the broader pt population.

Abstract Introduction: Quantitative 18fluorodeoxyglucose positron emission tomography (PET)/computed tomography assessment using total metabolic tumor volume (TMTV) and tumor lesion glycolysis (TLG) measurements has been found promising as an objective method to predict survival in diffuse large B-cell lymphoma (DLBCL) patients (pts). However, the methodology for PET-derived metrics is still evolving, and their predictive value is yet to be proven in large-scale, prospective, multicenter studies. We investigated the prognostic value of baseline maximum standardized uptake value (SUVmax), TMTV and TLG for progression-free survival (PFS) in a large pt cohort treated with obinutuzumab (GA101; G) or rituximab (R) combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in the Phase 3 GOYA study (NCT01287741; Vitolo et al. J Clin Oncol 2017). Methods: Pts aged ≥18 years, with previously untreated, CD20-positive DLBCL and an International Prognostic Index (IPI) score ≥2 and low-risk pts with IPI scores of 1 (not due to age alone) or 0 (with bulky disease) were randomized 1:1 to receive 8 x 21-day cycles of G (1000mg intravenous [IV] on Days [D] 1, 8, and 15 of Cycle [C] 1 and D1, C2-8) or R (375mg/m2 IV on D1, C1-8) plus 6 or 8 cycles of CHOP. All pts had a baseline and end of treatment (EOT) PET. PET images were segmented using an automated workflow program in MIM software, applying thresholds of 1.5 x liver background and a minimum volume of 1mL to the whole body PET images. The data were analyzed for the overall population and according to germinal center B-cell-like (GCB), unclassified, and activated B-cell-like (ABC) subtypes of DLBCL. TMTV, TLG, and SUVmax were split into 4 categories/levels according to the following quartiles: Q1, &lt;25%; Q2, 25-50%; Q3, 50-75%; and Q4, 75-100%, which were obtained based on their distribution in the available population. The reported hazard ratios (HRs) refer to stratified log-rank tests comparing Q2, Q3, and Q4 to Q1, adjusted for stratification factors of the study: IPI score (low [0-2], intermediate [3], and high [4-5]) and number of planned CHOP cycles (6 or 8). Results: Of 1418 enrolled pts, 1346 had a baseline PET scan and 1334 had detectable lesions. There was no statistical difference in PFS between the treatment arms (G vs R), thus the entire cohort was analyzed as a whole. Results of the predictive value of baseline TMTV for PFS are presented in quartiles in Figure 1, and results of the predictive value of TLG for PFS are presented in quartiles in Figure 2, for the overall PET intent-to-treat population. After a median follow-up of 29 months TMTV and TLG were highly predictive of PFS when comparing Q4 vs Q1: HR=2.21, 95% CI 1.48-3.29, p&lt;0.0001, and HR=1.91, 95% CI 1.28-2.85, p=0.0005, respectively. TMTV was also predictive of overall survival (OS): HR=2.63, 95% CI 1.55-4.46; p&lt;0.0001. However, SUVmax-based prediction of PFS was not statistically significant (HR=0.84, 95% CI 0.57-1.23, p=0.3782). Three-year PFS for pts in TMTV Q1, 2, 3 and 4 was 86% (95% CI 81-89%), 84% (95% CI 78-88%), 78% (95% CI 72-83%) and 66% (95% CI 59-71%), respectively. TMTV also showed a trend for a better prediction of PFS (Figure 3) and OS in pts with the unclassified and ABC DLBCL subtypes when compared with those with the GCB subtype. Conclusions: This large prospective study confirms baseline TMTV and TLG as predictors of PFS and OS in DLBCL after first-line immunochemotherapy, while SUVmax may not be a predictor. Furthermore, TMTV and TLG appear to be better predictors of survival for pts with the unclassified and ABC subtypes of DLBCL than for those pts with the GCB subtype. Further analyses are underway comparing these results with the predictive value of percentage change from baseline to EOT PET, Deauville score-based analysis of EOT PET, and the various molecular DLBCL subtypes.
