Abstract Background Nucleoside analogues such as cladribine can increase the efficacy of cytarabine (araC) by modulating deoxycytidine kinase. The addition of cladribine to standard 7+3 chemotherapy has been shown to improve survival in pts with AML (Holowiecki JCO 2012). Results of our part-1 phase-2 clinical trial (cladribine combined with intermediate dose araC and idarubicin (CLIA1)) reported promising results that exceeded pretreatment expectations for response and tolerability (Jain, et. al. ASH 2016). Based on that, and the benefit of higher doses of cytarabine in younger patients (UK-MRC AML, Willemze JCO 2014), we investigated a higher dose of araC in combination with cladribine and idarubicin (CLIA2). Methods Non-APL, non-core binding factor AML pts 18-65 yrs of age with adequate organ function were enrolled in 1 of 3 cohorts: de novo AML, secondary AML (s-AML), or relapsed/refractory AML (R/R). Induction was cladribine 5 mg/m2 IV over 30 minutes on days 1-5, followed by araC 2g/m2 IV on days 1-5, and idarubicin 10 mg/m2 IV days 1-3. Consolidation consisted of up to 5 more cycles of CLIA2 for 3 days instead of 5. Dose-adjustments were allowed for age and PS. Sorafenib or midostaurin was added for pts with FLT3 mutations which occurred in 35% of pts on this study. Prophylactic intrathecal therapy was offered to higher risk pts at count nadir during cycle 1. Mutation profiling was performed using next generation sequencing prior to starting therapy. Results 65 patients were enrolled, with a median age of 47 yrs (range, 24-65): 37 pts (57%) in the frontline, 12 (19%) pts in the s-AML, and 16 (25%) in the R/R cohorts. Pt characteristics and outcomes by cohort are outlined in Table 1. The most commonly detected mutations at baseline were TET2 (45%), DNMT3a (37%), FLT3 (35%), ASXL1 (28%), and NPM1 (28%). Of 35 evaluable pts in the frontline cohort, 31 responded (ORR=89%) with 27 CR (77%) and 4 CRi (11%). Among the responders, 61% were negative for minimal residual disease (MRD [-]) by multiparameter flow cytometry. In the s-AML cohort, 10 pts were evaluable with an ORR of 60% (6/10) with 5 CR (50%) and 1 CRp (10%); 4 (67%) were MRD [-]. In the R/R cohort, 14 pts, previously treated with a median of 1 (1-4) prior therapy were evaluable for response. There were 7 CR (50%), 1 CRi (7%), for ORR of 57%; and 63% were MRD [-]. The median OS was not reached in the frontline and s-AML cohorts with median follow up of 5.2 and 11.5, months, respectively. In the R/R cohort, the median follow up was 4.7 months and median OS was 6.7 months [Figure.1]. Relapse-free survival was not reached in frontline and salvage cohort, and was 9.1 months in s-AML with median follow up of 5.2, 3.9, and 3.5 months in frontline, s-AML, and salvage cohorts, respectively [Figure.2]. The regimen was well tolerated. The most common ≥ grade 3 possibly-related non-hematologic adverse events were fever/infection (38), bleeding (2), and abnormal liver function test (3). Conclusion The 3-drug combination with a higher dose of araC, CLIA2, is safe and effective in younger pts with AML. Compared to our prior experience in pts with s-AML, using higher dose of cytarabine in CLIA2 for this cohort seems to have the highest impact. This trend however was also seen in the salvage and frontline cohorts when compared to the results from CLIA1. Response rates for pts in the newly-diagnosed AML, s-AML, and in the salvage settings are promising and should be explored further in larger studies and compared to current standard regimens.

Introduction: The R-MegaCHOEP trial showed that dose-escalation of conventional chemotherapy necessitating autologous stem cell transplantation (ASCT) does not confer a survival benefit for younger patients (pts) with high-risk aggressive B-cell lymphoma in the Rituximab era (Schmitz et al., Lancet Oncology 2012; 13, 1250-1259). To describe efficacy and toxicity over time and document the long-term risks of relapse and secondary malignancy we present the 10-year follow-up of this study. Methods: In the randomized, prospective phase 3 trial R-MegaCHOEP younger pts aged 18-60 years with newly diagnosed, high-risk (aaIPI 2-3) aggressive B-cell lymphoma were assigned to 8 cycles of CHOEP (cyclophosphamide, doxorubcine, vincristine, etoposide, prednisone) or 4 cycles of dose-escalated high-dose therapy (HDT) necessitating repetitive ASCT both combined with Rituximab. Both arms were stratified according to aaIPI, bulky disease, and center. Primary endpoint was event-free survival (EFS). All analyses were calculated for the intention-to-treat population. This follow-up report includes molecular data based on immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) for MYC (IHC: 31/92 positive [40-100%], FISH: 14/103 positive), BCL2 (IHC: 65/89 positive [50-100%], FISH: 23/111 positive) and BCL6 (IHC: 52/86 positive [30-100%], FISH: 34/110 positive) and data on cell of origin (COO) classification according to the Lymph2CX assay (GCB: 53/88; ABC: 24/88; unclassified: 11/88). Results: 130 pts had been assigned to R-CHOEP and 132 to R-MegaCHOEP. DLBCL was the most common lymphoma subtype (~80%). 73% of pts scored an aaIPI of 2 and 27% an aaIPI of 3. 60% of pts had an initial lymphoma bulk and in 40% more than 1 extranodal site was involved. After a median observation time of 111 months, EFS at 10 years was 57% (95% CI 47-67%) in the R-CHOEP vs. 51% in the R-MegaCHOEP arm (42-61%) (hazard ratio 1.3, 95% CI 0.9-1.8, p=0.228), overall survival (OS) after 10 years was 72% (63-81%) vs. 66% (57-76%) respectively (p=0.249). With regard to molecular characterization, we were unable to detect a significant benefit for HDT/ASCT in any subgroup analyzed. In total, 16% of pts (30 pts) relapsed after having achieved a complete remission (CR). 23% of all relapses (7 pts) showed an indolent histology (follicular lymphoma grade 1-3a) and 6 of these pts survived long-term. In contrast, of 23 pts (77%) relapsing with aggressive DLBCL or unknown histology 18 pts died due to lymphoma or related therapy. The majority of relapses occurred during the first 3 years after randomization (median time: 22 months) while after 5 years we detected relapses only in 5 pts (3% of all 190 pts prior CR). 11% of pts were initially progressive (28 pts) among whom 71% (20 pts) died rapidly due to lymphoma. Interestingly, the remaining 29% (8 pts) showed a long-term survival after salvage therapy (+/- ASCT); only 1 pt received allogeneic transplantation. The frequency of secondary malignancies was very similar in both treatment arms (9% vs. 8%) despite the very high dose of etoposide (total 4g/m2)in the R-MegaCHOEP arm. We observed 2 cases of AML and 1 case of MDS per arm. In total 70 pts (28%) have died: 30 pts due to lymphoma (12%), 22 pts therapy-related (11 pts due to salvage therapy) (9%), 8 pts of secondary neoplasia (3%), 5 pts due to concomitant disease (2%) and 5 pts for unknown reasons. Conclusions: This 10-year long-term follow-up of the R-MegaCHOEP trial confirms the very encouraging outcome of young high-risk pts following conventional chemotherapy with R-CHOEP. High-dose therapy did not improve outcome in any subgroup analysis including molecular high-risk groups. Relapse rate was generally low. Pts with aggressive relapse showed a very poor long-term outcome while pts with indolent histology at relapse survived long-term. Secondary malignancies occurred; however, they were rare with no excess leukemias/MDS following treatment with very high doses of etoposide and other cytotoxic agents.

Abstract Abstract 3697 Introduction: Rituximab has been a useful treatment for patients with ITP; many hundreds of patients have been treated. 30–40% of patients will achieve a complete remission (CR: platelet count >150 × 109/l) with initial treatment and, of this group, the CR will last at least a year in almost all patients. However, emerging data suggests that at least 40% of these patients in CR will relapse between 1 and 3 years from initial treatment suggesting that long-term “cures” only occur in 20% of the initial patients. Therefore it would be desirable if CR's could be achieved in more patients and especially if these would be durable in more than 20%. One approach would be to use rituximab maintenance, however it results in suppression of B-cells for more than 2 years. Dexamethasone has also been used to achieve “cure” in ITP especially in adults at or near diagnosis. Cheng's study suggested that approximately 50% of patients would achieve a long-term response with only one 4-day cycle of high dose (40 mg/day) dexamethasone (N Engl J Med, 2003). A follow up study from GIMEMA suggested that 3–4 cycles of dexamethasone would be better than 1 cycle (Blood, 2007). Finally, Zaja's study suggested that rituximab plus one cycle of dexamethasone was superior to dexamethasone alone with a > 50% CR rate at 6 months (Blood, 2010). Therefore, we elected to perform a pilot study to explore the combination of rituximab with three cycles of dexamethasone at 14 day intervals. Methods: Patients with ITP with platelet counts < 30,000 off therapy and in need of treatment were enrolled. The standard dose (4 infusions of 375mg/m2) rituximab was given on days 1, 8, 15 and 22 and dexamethasone 40 mg (adjusted for size) on days 1–4, 15–18, and 29–32. Results: Fourteen patients between the ages of 4 and 53 years with ITP were treated with rituximab and dexamethasone (R&D) (Table 1). All had received previous steroid therapy as well as other treatments. The median platelet count was 40,000 at initiation of rituximab (range 7,000-230,000); several patients with low counts started with dexamethasone prior to initiating Rituximab to sustain their counts during initial treatment. Patients received rituximab weekly for between 2 and 4 doses and dexamethasone for either 2 or 3 courses at intervals between 1 and 8 weeks (median 2 week intervals). A summary of the results is shown in table 2 demonstrating short-lived platelet increases in response to dexamethasone in almost all patients. With short follow up, there were 7 CR's, 3 PR's and 4 NR's. If this was divided by duration of ITP prior to R&D, there were 4 CR's and 1 NR for ≤ 12 months and 3 CR, 3 PR, and 3 NR for > 12 months. More of the children who were treated had chronic disease than did adults explaining their apparently poorer response. Observed toxicities included hyperglycemia, grade 1 and 2 liver function abnormalities, weight gain, and 1 episode of colitis requiring hospitalization. Three patients opted to skip the third cycle of dexamethasone. Conclusion: A regimen of rituximab + 2–3 courses of dexamethasone is active in patients with pretreated ITP with appreciable but usually manageable toxicity. It appears to yield superior results if administered to patients within one year of diagnosis. This combination merits further exploration in a prospective clinical trial.

Abstract Abstract 801 Background: Ruxolitinib is a potent JAK1 & 2 inhibitor that has demonstrated superiority over traditional therapies for the treatment of MF. In the two phase 3 COMFORT studies, ruxolitinib demonstrated rapid and durable reductions in splenomegaly and improved MF-related symptoms and quality of life. COMFORT-II is a randomized, open-label study evaluating ruxolitinib versus BAT in patients (pts) with MF. The primary and key secondary endpoints were both met: the proportion of pts achieving a response (defined as a ≥ 35% reduction in spleen volume) at wk 48 (ruxolitinib, 28.5%; BAT, 0%; P < .0001) and 24 (31.9% and 0%; P < .0001), respectively. The present analyses update the efficacy and safety findings of COMFORT-II (median follow-up, 112 wk). Methods: In COMFORT-II, 219 pts with intermediate-2 or high-risk MF and splenomegaly were randomized (2:1) to receive ruxolitinib (15 or 20 mg bid, based on baseline platelet count [100-200 × 109/L or > 200 × 109/L, respectively]) or BAT. Efficacy results are based on an intention-to-treat analysis; a loss of spleen response was defined as a > 25% increase in spleen volume over on-study nadir that is no longer a ≥ 35% reduction from baseline. Overall survival was estimated using the Kaplan-Meier method. Results: The median follow-up was 112 wk (ruxolitinib, 113; BAT, 108), and the median duration of exposure 83.3 wk (ruxolitinib, 111.4 [randomized and extension phases]; BAT, 45.1 [randomized treatment only]). Because the core study has completed, all pts have either entered the extension phase or discontinued from the study. The primary reasons for discontinuation were adverse events (AEs; ruxolitinib, 11.6%; BAT, 6.8%), consent withdrawal (4.1% and 12.3%), and disease progression (2.7% and 5.5%). Overall, 72.6% of pts (106/146) in the ruxolitinib arm and 61.6% (45/73) in the BAT arm entered the extension phase to receive ruxolitinib, and 55.5% (81/146) of those originally randomized to ruxolitinib remained on treatment at the time of this analysis. The primary reasons for discontinuation from the extension phase were progressive disease (8.2%), AEs (2.1%), and other (4.1%). Overall, 70 pts (48.3%) treated with ruxolitinib achieved a ≥ 35% reduction from baseline in spleen volume at any time during the study, and 97.1% of pts (132/136) with postbaseline assessments experienced a clinical benefit with some degree of reduction in spleen volume. Spleen reductions of ≥ 35% were sustained with continued ruxolitinib therapy (median duration not yet reached); the probabilities of maintaining the spleen response at wk 48 and 84 are 75% (95% CI, 61%-84%) and 58% (95% CI, 35%-76%), respectively (Figure). Since the last report (median 61.1 wk), an additional 9 and 12 deaths were reported in the ruxolitinib and BAT arms, respectively, resulting in a total of 20 (14%) and 16 (22%) deaths overall. Although there was no inferential statistical testing at this unplanned analysis, pts randomized to ruxolitinib showed longer survival than those randomized to BAT (HR = 0.52; 95% CI, 0.27–1.00). As expected, given the mechanism of action of ruxolitinib as a JAK1 & 2 inhibitor, the most common new or worsened grade 3/4 hematologic abnormalities during randomized treatment were anemia (ruxolitinib, 40.4%; BAT, 23.3%), lymphopenia (22.6%; 31.5%), and thrombocytopenia (9.6%; 9.6%). In the ruxolitinib arm, mean hemoglobin levels decreased over the first 12 wk of treatment and then recovered to levels similar to BAT from wk 24 onward; there was no difference in the mean monthly red blood cell transfusion rate among the ruxolitinib and BAT groups (0.834 vs 0.956 units, respectively). Nonhematologic AEs were primarily grade 1/2. Including the extension phase, there were no new nonhematologic AEs in the ruxolitinib group that were not observed previously (in ≥ 10% of pts), and only 1 pt had a new grade 3/4 AE (epistaxis). Conclusion: In COMFORT-II, ruxolitinib provided rapid and durable reductions in splenomegaly; this analysis demonstrates that these reductions are sustained over 2 years of treatment in the majority of pts. Ruxolitinib-treated pts showed longer survival than those receiving BAT, consistent with the survival advantage observed in previous (Verstovsek et al. NEJM. 2012) and current analyses of COMFORT-I, as well as with the comparison of pts of the phase 1/2 study with matched historical controls (Verstovsek et al. Blood. 2012).

Abstract Introduction: Triplet therapies are used for treatment (Tx) of both transplant-eligible and -ineligible patients (pts) with newly diagnosed multiple myeloma (NDMM). Actual patterns and outcomes of Tx are not fully understood. Connect MM® is the first and largest multicenter, US-based, prospective observational cohort study designed to characterize Tx patterns and outcomes for pts with NDMM. This analysis describes demographic and disease characteristics of pts who received triplet Tx as an induction regimen and for whom transplant was or was not intended. The analysis explores the relationship of these factors with overall survival (OS) and other efficacy endpoints. Patients and Methods: Pts aged ≥ 18 y with NDMM within 60 days of diagnosis were eligible for enrollment regardless of disease severity, medical history, or comorbidities. Data including transplant intent (yes/no) was collected at baseline; follow-up data was collected quarterly thereafter. Based on the initial intent, 2 groups were identified: patients with intent to transplant who received transplant (TT) and pts with no intent to transplant who did not receive a transplant (NT). Triplet Tx was defined as the combination of ≥ 3 concurrent therapeutic agents in the first course of Tx (within 56 days of study entry). KM analysis adjusted for age was conducted for OS. Because decisions on use of transplant and triplet therapy are influenced by multiple factors, a multivariable Cox regression analysis was performed to evaluate the contribution of the triplet therapy (yes/no) to OS and was adjusted for other variables, including age, comorbidities, and ISS staging. Results: Between September 2009 and December 2011, 1493 pts were enrolled. This analysis was on 1436 pts: 650 pts with transplant intent and 786 pts without transplant intent. The data cutoff date was November 30, 2014, and the median follow-up for overall survival (OS) was 33.8 mos. Of pts with transplant intent, 451 (69%) received transplant (TT) and 199 (31%) did not. Of pts without transplant intent, 62 (8%) received transplant and 724 (92%) did not (NT). The abstract focuses on TT and NT groups only. NT pts tended to be older and have more advanced ISS staging and higher β2-microglobulin levels than TT pts (Table). The most common triplet regimen given during the first course treatment (within 56 days) was lenalidomide, bortezomib, and dexamethasone (RVd). RVd was administered to 34% of the NT pts (76/225) and 59% of the TT pts (152/257). The most common non-triplet regimen was bortezomib and dexamethasone (Vd), which was given to 31% of NT pts (156/499) and 38% of TT pts (73/194). Within the NT group, pts given triplet Tx had a lower risk of death than those who did not receive triplet Tx (P = .0013). The multivariable analysis found triplet Tx to be associated with a 36% reduced risk of death (hazard ratio [HR] = 0.64 [95% CI, 0.50-0.82]; P = .001). ISS disease stage (HR = 1.43 [95% CI, 1.21-1.69]; P < .001) and history of diabetes (HR = 1.38 [95% CI, 1.08-1.78]; P = .012) were negative prognostic factors for OS. Within the TT group, pts who received triplet Tx did not attain an OS benefit (P = .8993), and no baseline characteristics were significantly associated with OS. These results may be limited by other factors not considered that may have influenced physicians' choice of treatment, including the use of maintenance therapy and a short follow-up period of 33.8 months. Conclusions: Triplet Tx as a first regimen is associated with longer OS in pts without transplant intent who did not receive a transplant. RVd and Vd were the most common first Tx regimens, respectively. Continued follow-up of these pts and enrollment of an additional cohort will provide additional data with mature follow-up. Table 1.

Abstract Introduction. Prognosis of patients (pts) with R/R Philadelphia chromosome-positive (Ph+) ALL is dismal despite the introduction of tyrosine kinase inhibitors (TKI) which may be used as single agents or in combination regimens. Blinatumomab is a bispecific T-cell engaging (BiTE®) antibody construct that has shown antileukemic activity. Among adults with R/R Ph-negative ALL receiving blinatumomab, 43% achieved complete remission (CR) or CR with partial hematologic recovery (CRh) during the first two cycles (Topp MS et al. Lancet Oncol 2015;16:57). We evaluated the efficacy and tolerability of blinatumomab in pts with R/R Ph+ ALL who progressed after or were intolerant to a 2nd or later (2+) generation TKI. Methods. Eligible adult pts (≥18 years) had Ph+ B-precursor ALL and had relapsed after or were refractory to at least one 2+ generation TKI; or were intolerant to 2+ generation TKI and intolerant or refractory to imatinib. All pts had to have >5% blasts in the bone marrow and Eastern Cooperative Oncology Group performance status ≤ 2. Blinatumomab was dosed by continuous IV infusion (4 weeks on/2 weeks off) for up to 5 cycles (9 μg/d on days 1-7 in cycle 1, and 28 μg/d thereafter). The primary endpoint was CR or CRh during the first two cycles; minimal residual disease (MRD) response based on RT-PCR amplification of BCR-ABL per central laboratory, relapse-free survival (RFS), overall survival (OS), and allogeneic hematopoietic stem cell transplant (alloHSCT) rate were key secondary endpoints. Complete MRD response was defined as no RT-PCR amplification of BCR-ABL at a sensitivity of 10-5. Results. Of 45 treated pts, 44 were resistant to 2+ generation TKI; one patient was resistant to imatinib and never exposed to 2+ generation TKI (protocol deviation). 53% of pts were men. Median (range) age was 55 (23-78) years (≥65 years, 27%). Ten pts (22%) had a BCR-ABL gene with T315I mutation. All pts had received prior TKI (dasatinib, 87%; ponatinib, 51%; imatinib, 56%; nilotinib, 36%; bosutinib, 2%), with 60% having received ≥ 2 prior 2+ generation TKI; most pts (96%) had received prior chemotherapy. 38% of pts had ≥ 2 prior relapses and 44% had prior alloHSCT. Efficacy outcomes for key endpoints are shown in the table. 16 pts achieved CR/CRh during the first two cycles for a response rate of 36% (95% CI: 22%, 51%); of those, 14 pts achieved CR, most of them (10/14, 71%) in cycle 1. The patient who never received 2+ generation TKI did not respond to treatment. 12 of the 14 pts (86%) with CR and two of the two pts with CRh achieved a complete MRD response. Among the 10 pts with T315I mutation, four achieved CR/CRh; all four also achieved a complete MRD response. Eight CR/CRh responders (50%) relapsed, three during treatment (including two with CR who did not achieve complete MRD response). One patient died in CR post alloHSCT. Median (95% CI) RFS was 6.7 (4.4, not estimable) months (median follow-up, 9.0 months); median OS was 7.1 (5.6, not estimable) months (median follow-up, 8.8 months). Patient incidence of grade ≥ 3 treatment-emergent adverse events (AEs) was 82%, most commonly febrile neutropenia (27%), thrombocytopenia (22%), anemia (16%), and pyrexia (11%). Five pts had fatal AEs; one (septic shock) was considered treatment-related by the investigator. Three pts discontinued because of AEs. Cytokine release syndrome (CRS) occurred in three pts (all grade 1 or 2). 21 pts (47%) had neurologic events (paraesthesia, 13%; confusional state, 11%; dizziness, 9%; tremor, 9%); three pts had grade 3 neurologic events (aphasia, hemiplegia; and depressed level of consciousness and nervous system disorder), one of which (aphasia) required treatment interruption. Conclusion. In this population of pts with R/R Ph+ ALL who have very poor prognosis after failure of 2+ generation TKI therapy, treatment with CD19-targeted immunotherapy blinatumomab as single agent showed antileukemic activity. AEs were consistent with those previously reported for pts with R/R Ph-negative ALL treated with blinatumomab. Table 1. Table 1.

Abstract Background: Current chemotherapy regimens in children with ALL produce disease-free survival (DFS) rates of greater than 80%. In contrast, adults with ALL have a much poorer prognosis, with DFS rates of 30-40%. Recent prospective studies suggest that young adults may have superior outcomes when treated with intensive pediatric regimens. We recently reported a 4-yr DFS and overall survival (OS) of 69% (n=78 who achieved CR) and 67% (n=92), respectively (DeAngelo et al. Leukemia 2015) using a native E. coliasparaginase based regimen. This phase II successor trial was performed to determine if a pediatric regimen using pegylated-asparaginase (peg-asp) could be feasibly administered to adults. Methods: Patients (pts) between 18-50 yrs with de novo ALL were eligible. The primary objective of this study was to determine the feasibility of a single dose of peg-asp during induction and of delivering peg-asp every 2 wks during a 30 wk consolidation period. The therapeutic backbone of this protocol was based on the very high-risk arm of the DFCI Childhood ALL Consortium Protocol 05-01. Pts received induction chemotherapy, which included doxorubicin, prednisone, vincristine, pegylated-asparaginase (peg-asp), and triple intrathecal therapy. Consolidation I consisted of a course of high-dose methotrexate, followed by a BFM-like intensification and a course of high-dose cytarabine, etoposide and dexamethasone. CNS prophylaxis included triple intrathecal therapy and cranial radiation. Intensification therapy consisted of eight 3-wk courses of doxorubicin, vincristine, dexamethasone, 6-mercaptopurine and 30 wks of IV peg-asp initially dosed at 2500 IU/m2every 2 wks. Continuation therapy consisted of 3 wk courses of vincristine, dexamethasone, methotrexate and 6-mercaptopurine for a total of 2 yrs from complete remission (CR). Imatinib at 600 mg/d was administered to those pts who were Philadelphia chromosome (Ph) positive. Results: Of 112 pts enrolled, 110 were eligible. The first 65 pts were treated with the initial study design of IV peg-asp during induction and peg-asp every two wks for 15 doses during consolidation. However, due to the high frequency of asparaginase toxicities mainly hyperbilirubinemia, peg-asp was replaced with native E. coli asp at a dose of 25,000 IU/m2 IM during induction and the dose and frequency peg-asp was decreased to 2000 IU/m2 every 3 wks during the consolidation phase in the subsequent 45 pts. The median age was 32 yrs, (range, 18-50), 61% were male, 82% had B-lineage phenotype, and 21 were Ph positive. The CR rate after 4 wks was 89%. 70 pts had the opportunity to receive peg-asp intensification therapy (42 at the 2500 IU/m2 every 2 wks schedule and 28 on the 2000 IU/m2 every 3 wk schedule). Of the 42, 18 pts (43%; 80% CI, 32-54%) on the 2 wk schedule completed at least 13 of 15 doses of peg-asp (26 wks) and 22 of 28 pts (79%; 80% CI, 65-88%) on the 3 wk schedule completed at least 8 of 10 doses of peg-asp, which met the feasibility endpoint (lower bound CI > 60%). The median asp levels post the induction dose of peg-asp were 0.025, 0.78, 0.28, 0.10, at baseline, 7, 11 and 25 days and >0.20 for each consolidation time point for both the 2 and 3 wk cohorts. Two deaths occurred during induction therapy (sepsis; CNS hemorrhage). Post-induction four pts developed pancreatitis, 14 pts had an allergic reaction to the asp, 12 pts developed osteonecrosis, 2 had a bone fracture, 13 pts had thrombosis/embolism and 32 pts had a grade 3-4 neutropenic infection. With a median follow-up time of 39 mos, the estimated 3-yr DFS is 73% for those who achieved a CR (n=90) and the estimated 3-yr OS is 75%. Conclusions: The administration of a dose intensified pediatric regimen with peg-asp to adults with ALL is feasible. However, the dose and schedule of peg-asp that is well-tolerated in adults is lower and less frequent as compared to that of pediatric pts. Although the DFS and OS are high for an adult cohort, longer follow up is needed. Pediatric-like therapies, including those using intensive peg-asp, are tolerable in young adults with ALL and represent a major therapeutic advance. Table 1.

Abstract Background: Thrombocytopenia occurs in ~50% of patients with low/int-1 risk myelodysplastic syndrome (MDS) and is associated with reduced survival. In a placebo (PBO)-controlled study, 250 patients with MDS were randomized 2:1 to receive weekly romiplostim or PBO. In the original June 2011 analysis, romiplostim reduced clinically significant bleeding events [hazard ratio (HR) romiplostim vs PBO 0.83, 95% CI: 0.66−1.05, P = 0.13] and platelet transfusions (relative risk 0.77, 95% CI: 0.66−0.88, P<0.001) and increased IWG hematologic improvement platelets (HI-P) incidence (odds ratio 15.6, 95% CI: 4.7−51.8, P<0.001). Peripheral blast count increases >10% were more frequent with romiplostim (25/167, 15%) than PBO (3/83, 3.6%) and resolved after discontinuation in most cases. In February 2011, the DMC recommended that treatment with study drug be discontinued as the potential benefit seen in the reduction of bleeding did not outweigh the potential risk for disease progression to AML, and that transient increases in blast cell counts might put patients at risk for diagnosis of and treatment for AML. Patients were moved into long-term follow-up (LTFU). Previously reported (Giagounidis et al, Cancer 2014) 58-week incidence of AML was 6.0% (N = 10) for romiplostim and 4.9% for PBO (N = 4); HR 1.20 (95% CI: 0.38−3.84). This report provides final 5-year LTFU data. Methods: Eligible patients were receiving only supportive care and had IPSS low/int-1 risk MDS and platelets 1) ≤20 × 109/L or 2) ≤50 × 109/L with a history of bleeding. Disease progression to AML was defined as 1) ≥20% blasts in bone marrow or peripheral blood after 4 weeks following discontinuation of romiplostim; 2) pathology consistent with leukemia; or 3) antileukemic treatment. Results are presented by treatment group. Results: At baseline, median (Q1, Q3) age was 70 (61, 77) years, the majority (59%) of patients were male; 27.6% were IPSS low risk and 72.4% were int-1 risk. WHO classifications were RCMD: 67.6%, RAEB-1: 13.2%, MDS-U: 11.2%, RA: 4.4%, RCMD-RS: 2.4%, RARS: 0.8%, and RAEB-2: 0.4%. Of 250 patients in the study, 210 entered LTFU and 66 completed the 5 years of LTFU; median (Q1, Q3) follow-up was 27.5 (10.8, 58.7) months. Reasons for discontinuation (death, lost to follow-up, and consent withdrawal) during LTFU were similar in both groups. During the active study period and LTFU, death was reported in 93 (55.7%) patients in the romiplostim group and 45 (54.2%) patients in the PBO group (HR romiplostim vs PBO 1.03, 95% CI: 0.72−1.47) (Figure); mortality rates were greater in those with IPSS int-1 vs low risk for both groups (Table). AML was reported in 20 (11.9%) patients in the romiplostim group and 9 (11.0%) patients in the PBO group (HR 1.06, 95% CI: 0.48−2.33). The proportions of patients who either died or developed AML were 56.9% (N = 95) in the romiplostim group and 55.4% (N = 46) in the PBO group (HR for AML-free survival 1.04, 95% CI: 0.73−1.48) (Figure). Nearly half (N = 14, 48%) of the 29 AML cases occurred in patients who were RAEB-1 at screening (none RAEB-2), and 6 cases were diagnosed because of anti-AML treatment use alone (Table). In LTFU, patient-reported use of MDS therapy (eg, azacitidine or cyclosporine) was 42.8% (N = 59, 95% CI: 34.4%−51.5%) in the romiplostim group and 31.4% (N = 22, 95% CI: 20.9%−43.6%) in the PBO group. AML therapy (eg, chemotherapy) was used in 14 (10.2%) patients in the romiplostim group and 7 (10.0%) patients in the PBO group. Conclusions: Following the decision in 2011 to stop study drug secondary to increased AML rates at that time and transient blasts increases, final 5-year LTFU HRs (romiplostim vs placebo) for death or progression to AML, respectively, are 1.03 (95% CI: 0.72−1.47) and 1.06 (95% CI: 0.48−2.33). In conclusion, romiplostim reduced bleeding events and platelet transfusions, with no increase in AML incidence or impact on survival. Disclosures Kantarjian: Amgen Inc.: Research Funding.

Abstract Background: Ibrutinib (ibr), a first-in-class, once-daily Bruton's tyrosine kinase inhibitor, is approved by the US FDA for treatment of patients (pts) with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including pts with del17p. The phase 1b/2 PCYC-1102 trial showed single-agent efficacy and tolerability in treatment-naïve (TN; O'Brien, Lancet Oncol 2014) and relapsed/refractory (R/R) CLL/SLL (Byrd, N Engl J Med 2013). We report efficacy and safety results of the longest follow-up to date for ibr-treated pts. Methods: Pts received 420 or 840 mg ibr QD until disease progression (PD) or unacceptable toxicity. Overall response rate (ORR) including partial response (PR) with lymphocytosis (PR-L) was assessed using updated iwCLL criteria. Responses were assessed by risk groups: unmutated IGVH, complex karyotype (CK; ≥3 unrelated chromosomal abnormalities by stimulated cytogenetics assessed by a reference lab), and in hierarchical order for del17p, then del11q. In the long-term extension study PCYC-1103, grade ≥3 adverse events (AEs), serious AEs, and AEs requiring dose reduction or discontinuation were collected. Results: Median age of the 132 pts with CLL/SLL (31 TN, 101 R/R) was 68 y (range, 37-84) with 43% ≥70 y. Baseline CK was observed in 41/112 (37%) of pts. Among R/R pts, 34 (34%) had del17p, 35 (35%) del11q, and 79 (78%) unmutated IGVH. R/R pts had a median of 4 prior therapies (range, 1-12). Median time on study was 46 m (range, 0-67) for all-treated pts, 60 m (range, 0-67.4) for TN pts, and 39 m (range, 0-67) for R/R pts. The ORR (per investigator) was 86% (complete response [CR], 14%) for all-treated pts (TN: 84% [CR, 29%], R/R: 86% [CR, 10%]). Median progression-free survival (PFS) was not reached (NR) for TN and 52 m for R/R pts with 60 m estimated PFS rates of 92% and 43%, respectively (Figure 1). In R/R pts, median PFS was 55 m (95% confidence intervals [CI], 31-not estimable [NE]) for pts with del11q, 26 m (95% CI,18-37) for pts with del17p, and NR (95% CI, 40-NE) for pts without del17p, del11q, trisomy 12, or del13q. Median PFS was 33 m (95% CI, 22-NE) and NR for pts with and without CK, and 43 m (95% CI, 32-NE) and 63 m (95% CI, 7-NE) for pts with unmutated and mutated IGVH, respectively(Figure 2). Among R/R pts, median PFS was 63 m (95% CI, 37-NE) for pts with 1-2 prior regimens (n=27, 3 pts with 1 prior therapy) and 59 m (95% CI, 22-NE) and 39 m (95% CI, 26-NE) for pts with 3 and ≥4 prior regimens, respectively. Median duration of response was NR for TN pts and 45 m for R/R pts. Pts estimated to be alive at 60 m were: TN, 92%; all R/R, 57%; R/R del17p, 32%; R/R del 11q, 61%; R/R unmutated IGVH, 55%. Among all treated pts, onset of grade ≥3 treatment-emergent AEs was highest in the first year and decreased during subsequent years. With about 5 years of follow-up, the most frequent grade ≥3 AEs were hypertension (26%), pneumonia (22%), neutropenia (17%), and atrial fibrillation (9%). Study treatment was discontinued due to AEs in 27 pts (20%) and disease progression in 34 pts (26%). Of all treated pts, 38% remain on ibr treatment on study including 65% of TN pts and 30% of R/R pts. Conclusions: Single-agent ibrutinib continues to show durable responses in pts with TN or R/R CLL/SLL including those with del17p, del11q, or unmutated IGVH. With extended treatment, CRs were observed in 29% of TN and 10% of R/R pts, having evolved over time. Ibrutinib provided better PFS outcomes if administered earlier in therapy than in the third-line or beyond. Those without CK experienced more favorable PFS and OS than those with CK. Ibrutinib was well tolerated with the onset of AEs decreasing over time, allowing for extended dosing for 65% of TN and 30% of R/R pts who continue treatment.

Abstract Background: Multiple myeloma remains incurable despite impressive array of available novel agents and therapeutic strategies. Allogeneic hematopoietic cell transplantation (HCT) remains the only potentially curative option for patients with multiple myeloma but it is limited by its toxicities. We previously reported initial result of a phase 2 study of upfront allogeneic HCT in myeloma patients achieving at least very good partial response (VGPR) after initial therapy (Nishihori, et al. ASH 2013 abstract 3390) and here we report more mature results after a median follow up of 3 years. Methods: Twenty seven myeloma patients received allogeneic HCT between 01/2010 and 02/2015 at Moffitt Cancer Center (NCT 00948922). Eligible patients were age ≤ 60, achieving first ≥ VGPR or complete response (CR), and have 8/8 HLA-matched related or unrelated donors. Conditioning regimen consisted of fludarabine 30 mg/m2 for 4 days (days -6, -5, -4, and -3) and melphalan 70 mg/m2 for 2 days (days -4 and -3) followed by a single dose of bortezomib 1.3 mg/m2 on day -3 (Flu/Mel/Vel regimen). GVHD prophylaxis was initially left to the discretion of physicians but later modified to only tacrolimus/methotrexate. No maintenance therapy was prescribed after allogeneic HCT. Results: The median age at transplant was 50 (range, 25-58) years. Disease status at the time of allogeneic HCT was VGPR (n=17: 63%) and CR/stringent CR (n=10: 37%). All patients received unmanipulated peripheral blood stem cell grafts from HLA-matched related donors (n=14) or HLA-matched unrelated donors (n=13). Graft-versus-host disease (GVHD) prophylaxis was tacrolimus plus either methotrexate (n=19: 70%), or mycophenolate mofetil (n=4), or sirolimus (n=4). All patients achieved neutrophil engraftment with a median of 15 (range, 11-19) days. Platelet engraftment was achieved with a median of 17 (range, 13 - 35) days and 2 patients did not recover platelets. The cumulative incidences of grades II-IV and grades III-IV acute GVHD at day 100 were 63.6% (95% confidence interval (CI): 43.1-81.1) and 19.6% (95%CI: 5.4-39.9), respectively. The cumulative incidence of moderate to severe chronic GVHD was 56.4% (95%CI: 36.3-75.5) at 1-year. The cumulative incidences of transplant-related mortality at day 100, 1 year and 2 years were 7.4% (95%CI: 0.8-20.0), 11.1% (95%CI: 2.7-25.4), and 11.1% (95%CI: 2.7-25.4), respectively. Progression-free survival estimates at 1, 2, and 3 years were 74.1% (95%CI: 53.2-86.7), 65.1% (95%CI: 43.3-80.2), and 65.1% (95%CI: 49.9-87.5), respectively. With a median follow up of 39 months for surviving patients, overall survival estimates at 1, 2 and 3 years were 85% (95%CI: 64.9-94.1), 75.4% (95%CI: 52.6-88.3), and 69.1% (95%CI: 53.8-93.5), respectively. Conclusions: The results of the this phase 2 trial of upfront allogeneic HCT with fludarabine/melphalan/bortezomib (Flu/Mel/Vel) conditioning are promising and provide the rationale for reasonable potentially curative option to younger and fit patients who are eligible for upfront intensive consolidation strategy. This approach may be potentially valuable for those with high-risk myeloma and a multicenter study is currently being conducted (BMT CTN protocol 1302:NCT02440464).

Abstract β-globin gene transfer into hematopoietic stem cells (HSCs) has the potential to reduce or eliminate the symptoms and long-term complications of severe sickle cell disease (SCD). LentiGlobin Drug Product (DP) is a gene therapy product containing autologous CD34+ cells transduced with the BB305 lentiviral vector. BB305 encodes a human β-globin gene containing a single point mutation (AT87Q) designed to confer anti-sickling properties similar to those observed in fetal hemoglobin (γ-globin). In two ongoing studies, subjects with transfusion-dependent β-thalassemia (Studies HGB-204 and HGB-205) or SCD (Study HGB-205) receiving LentiGlobin DP have demonstrated sustained expression of 3-9 g/dL therapeutic hemoglobin (HbAT87Q) and have shown marked improvements in clinical symptoms 1 year post-treatment. Study HGB-206 is a multi-center, Phase 1/2 safety and efficacy study of LentiGlobin DP in adults with severe SCD. We previously (ASH 2015) presented results from 2 subjects, who had 3 and 6 months of follow-up after LentiGlobin treatment. We now present data from 7 treated subjects, 4 of whom have ≥6 months of follow-up data. Subjects (≥18 years of age) with severe SCD (history of recurrent vaso-occlusive crisis [VOC], acute chest syndrome, stroke, or tricuspid regurgitant jet velocity of >2.5 m/s) were screened for eligibility. Following bone marrow harvest (BMH), CD34+ cells were transduced with the BB305 vector. Subjects underwent myeloablative conditioning with busulfan prior to infusion of the transduced cells. Safety assessments include adverse events (AEs), integration site analysis (ISA) and surveillance for replication competent lentivirus (RCL). After infusion, subjects are monitored for hematologic engraftment, vector copy number (VCN), HbAT87Q expression, and other laboratory and clinical parameters. As of July 2016, 7 subjects with severe SCD (median age: 26 years, range 18-42 years) have received LentiGlobin DP in this study. All subjects successfully underwent BMH, with a median of 2 harvests required (range 1-4). Fifteen Grade 3 AEs in 5 subjects were attributed to BMH: pain (n=10), anemia (n=3) and VOC (n=2); all resolved with standard measures. Table 1 summarizes cell harvest, DP characteristics, and lab results. The median LentiGlobin DP cell dose was 2.1x10e6 CD34+ cells/kg (range 1.6-5.1) and DP VCN was 0.6 (0.3-1.3) copies/diploid genome. Median post-infusion follow-up as of July 2016 is 7.1 months (3.7-12.7 months). All subjects successfully engrafted after receiving LentiGlobin DP, with a median time to neutrophil engraftment of 22 days (17-29 days). The toxicity profile observed from start of conditioning to latest follow-up was consistent with myeloablative conditioning with single-agent busulfan. To date, there have been no DP-related ≥Grade 3 AEs or serious AEs, and no evidence of clonal dominance or RCL. The BB305 vector remains detectable at low levels in the peripheral blood of all subjects infused, with median VCN 0.08 (0.05-0.13, n=7) at last measurement. All subjects express HbAT87Q, with a median of 0.4g/dL (0.1-1.0 g/dL, n=7) at 3 months; most subjects demonstrated modest increases over time, and the 2 subjects with the longest follow-up expressed 0.31 and 1.2 g/dL HbAT87Q at 9 months. All 4 subjects with ≥6 months of follow-up experienced multiple VOCs in the 2 years prior to study entry (2-27.5 VOCs annually). Since LentiGlobin DP infusion, 3 of these 4 subjects have had fewer VOCs, although this trend may be confounded by the short follow-up, the effects of transplant conditioning, and/or post-transplant RBC transfusions. The decrease in VCN between DP and peripheral cells contrasts with previous reports of successful LentiGlobin gene therapy in ongoing studies HGB-204 and HGB-205. The relatively low in vivo VCN in this study appears to result in the lower HbAT87Q expression seen to date. We are exploring multiple hypotheses as to the etiology of the VCN drop between DP and peripheral blood, including the adverse impact of sickle marrow pathology on HSCs, the adequacy of myeloablation, and the magnitude of the transduced cell dose. We will provide an update on study data and ongoing efforts to increase in vivo VCN in patients with SCD, such as increasing the transduced cell dose through alternate HSC procurement methods or enhancing the DP VCN through manufacturing improvements.
