Abstract Abstract 920 CLL refractory to purine analogues (e.g. fludarabine, F) or with 17p- is associated with very poor prognosis. Alemtuzumab is active in F-refractory CLL, and has proven efficacy in patients (pts) with 17p-. However, outcome of F-refractory CLL is still poor in terms of remission rate and duration of remission. The multinational, multicenter CLL2O trial aims at achieving a higher remission rate by adding high-dose dexamethasone to alemtuzumab, and prolongation of remission duration and survival by alemtuzumab maintenance or allogeneic stem-cell transplantation (allo-SCT). Pts with CLL refractory (no PR/CR or PR/CR < 6 months) to F-based (e.g. FR, FC, FCR) or similar chemotherapy (i.e. pentostatin, cladribine, bendamustine), or exhibiting 17p- (untreated or at relapse) were eligible if they had “active disease”. Treatment was with subcutaneous alemtuzumab 30 mg weekly × 3 for 28 days, combined with oral dexamethasone 40 mg on days 1–4 and 15–18, and prophylactic pegfilgrastim 6 mg days 1 and 15. Depending on the remission status, pts were treated for up to 12 weeks. If CR was documented at 4 or 8 weeks, or at least SD was achieved at 12 weeks, consolidation was scheduled with either allo-SCT or alemtuzumab maintenance with 30mg weekly every 14 days for up to 2 years (yrs). Decision for one of the two consolidation options was at discretion of patient and physician. From January 2008 to July 2010, 80 pts were enrolled at 22 centers and 79 were eligible; F-refractory (n=31), 17p- without prior therapy (n=31), and 17p- in relapse (n=17). Median age was 65 yrs in the F-refractory (range 38–76) and 17p- 1st-line group (36-76), and 60 yrs for the 17p- relapse group (54-73) with male predominance (F-refractory 74%, 17p- 1st-line 71%, 17p- relapse 82%). In the 17p- 1st-line and relapse groups, 52% and 50% were stage Binet C and exhibit reduced performance status (ECOG 1–2), compared to 81% Binet C and 60% ECOG 1–2 for the F-refractory cohort. Pretreated pts had received a median of 2 prior lines (F-refractory 1–6; 17p- relapse 1–5), and 5 pts had received prior SCT. In the F-refractory group, 16% of pts had 11q- and 52% had 17p-. IGHV was unmutated in 64% of 17p- groups and 72% in the F-refractory group. The median levels of ß2-MG / TK were 4.35 / 35.40 in the 17p- groups and 4.12 / 22.65 in the F-refractory group. Treatment data are currently available for 50 pts who completed induction therapy; F-refractory (n=19),17p- 1st-line (n=22), 17p- relapse (n=9). Full treatment duration (12 weeks) could be achieved in 47% F-refractory, 67% 17p- relapsed and 82% 17p- 1st-line pts. In the latter cohort, early stop of therapy was mainly correlated with CR, while in the F-refractory cohort with disease progression (n=2) and infections (n=5, 4 with no documented response). Response rates (ORR / CR) were 47% / 0% in the F-refractory cohort, 78% / 0% in the 17p- relapsed, and 100% / 23% in the 17p- 1st-line cohorts (as compared to this, ORR / CR was 71.4% / 4.8% with FCR in the 17p- 1st-line group of CLL8). Adverse events during treatment were mostly grade 1/2 apart from hematotoxicity. Grade 3/4 non-CMV infection occurred in 35% of F-refractory, 12% of 17p- relapsed, and 16% of 17p- 1st-line pts. CMV reactivation was observed in 32 % of the 17p- 1st-line pts, and less for the pretreated groups (F-refractory 16%, 17p- relapsed 18%). All CMV episodes were successfully treated, and there was no CMV-related death. Among 18 pts documented to receive alemtuzumab maintenance treatment, so far 3 SAEs have been reported: ITP (n=1, twice in the same pt), and fever / diarrhea / thyroiditis (n=1). At a median follow-up of 41.9 weeks (maintenance 54.7 weeks, allo-SCT 29 weeks), there were 7 (37%) deaths in the in the F-refractory cohort, 2 due to disease progression, and 5 due to infection. For the 17p- relapsed group, 3 progressions and 3 deaths were reported, with one case in each treatment option (SCT/maintenance), and one pt in salvage therapy. In the 17p- 1st-line cohort, 4 progressions occurred, 2 pts died, both in maintenance therapy. At 12 months, estimated overall survival was 54%, 66% and 100% in the F-refractory, 17p- relapse, and 17p- 1st-line cohorts, respectively. Accrual is currently ongoing with a target enrolment of 122 pts and updated results will be presented at the meeting.

Methods: As reported previously, PVX-410 Multi-Peptide Vaccine (OncoPep, Inc.) is being developed for the treatment of SMM. PVX-410 consists of 4 human leukocyte antigen-A2 (HLA-A2), synthetic 9-mer peptides from unique regions of 3 multiple myeloma (MM)-associated antigens (XBP1 US184-192; XBP1 SP367-375; CD138260-268; and CS1239-247) emulsified in Montanide® ISA-720 VG (Seppic). Adults with SMM at high risk of progression to active MM and were HLA-A2-positive were eligible. The primary objective of this study was to determine the tolerability of PVX-410, initially as monotherapy. Immune response and change in M protein and free light chain ratio (FLC) were also assessed. PVX-410 alone was safe and immunogenic in the initial 12 patients treated, with all 12 having positive immune response to at least 1peptide, as determined by interferon-gamma enzyme-linked immunosorbent spot (Elispot) and tetramer assays. Given its immunomodulatory properties, it was hypothesized that co-administration of lenalidomide (len; Celgene Corporation) would enhance the T cell-mediated immune response induced by PVX-410. Accordingly, the tolerability, immunogenicity, and anti-MM activity of PVX-410+len was then investigated. Results in the PVX-410 alone cohort were previously reported. In the PVX-410+len cohort, patients received a dose of PVX-410, 0.8mg (0.2mg/peptide / 0.8mg total dose) subcutaneously plus 0.5 mL (1mg) Hiltonol® (poly-ICLC; Oncovir, Inc.) intramuscularly every 2 weeks for a total of 6 doses with 3 standard cycles of len (25 mg orally) on Days 1-21 every 28 days, without dexamethasone. Patients are followed for 12months post-treatment. Blood samples for immune response evaluation are collected at Week 0 (Baseline; pre-dose), 2, 4, and 8 during treatment and at Months 1, 3, 6, 9, and 12 post-treatment. Disease response is assessed at the same time points, except Weeks 0 and 2, using International Myeloma Working Group and modified European Group for Blood and Bone Marrow Transplant criteria. Results: Overall, 22 patients have been enrolled, with ages ranging from 39 to 82 years. Ten patients were enrolled in the PVX-410+len cohort, with 9 evaluable for response. All 10 patients received at least 1 cycle of len; 8 received all 3 cycles; 1 received 1 cycle before discontinuing due to a deviation; and 1 completed 2 cycles as of the cutoff date. One patient had 7 of 21 planned doses held due to neutropenia related to lenalidomide, but resumed the next cycle at a reduced dose (from 25 mg to 20 mg). Immunogenicity data with PVX-410+len and PVX-410 alone, as determined via intracellular cytokine staining and tetramer analysis, will be presented. With PVX-410 alone, 5 patients, 2 of 3 with the low-dose of 0.4 mg (0.1mg/peptide) and 3 of 9 at the target-dose (0.2 mg/peptide), experienced progression to active disease within 9 months post-treatment, and 7 had stable disease (SD) at the last follow up visit in the 12 month follow up period. With PVX-410+len, 5 patients have experienced partial or minimal responses and 3 have experienced SD. Durability of response is assessed through the 12-month study period; 1 patient has progressed to active myeloma during this time. PVX-410 was well-tolerated alone and with len. Most adverse events (AEs) have been ≤Grade 2 and non-serious. AEs seen more frequently with PVX-410+len versus PVX-410 alone are expected with len and include hematologic abnormalities (neutropenia, anemia, thrombocytopenia), gastrointestinal disorders (nausea, diarrhea, constipation), skin and cutaneous disorders (rash, pruritus), and myalgia. There was 1serious AE in the combination cohort (pneumonia), considered possibly related to len and unrelated to PVX-410. Conclusions: Six doses of PVX-410 were well tolerated in 22 patients with SMM. Additional AEs seen with PVX-410+len versus PVX-410 alone were expected with the addition of len to the treatment regimen. An immune response to the vaccine was seen in all patients treated with PVX-410 alone and is expected to be enhanced with PVX-410+len; these data will be presented. Based on the promising findings to date, an evaluation of PVX-410 in combination with an antibody to the programmed cell-death-1-ligand complex (PD1/PDL1) is planned to begin in 2015.

Abstract Abstract 3828 Introduction: Attention is being paid to HRQOL when monitoring hematologic disorders or the impact of treatments on those disorders. Minimal HRQOL data have been published on multiple myeloma (MM) patients (pts) in the United States (US). This analysis characterizes variation in the HRQOL of pts with active, symptomatic MM by International Staging System (ISS) stage and ECOG status. Methods: Data were collected as part of Connect MM®, a prospective observational registry initiated in September 2009 involving centers in the US. Data on pt demographics and clinical characteristics were provided by clinicians. HRQOL was reported by pts in the clinic at enrollment, within two months of diagnosis. Pts completed 3 psychometrically validated instruments: EQ-5D, Brief Pain Inventory (BPI), and Functional Assessment of Cancer Therapy-Multiple Myeloma (FACT-MM). Standard analyses were conducted of each instrument given clinical characteristics at that time. Reported mean BPI, EQ-5D and FACT-MM scores were analyzed by ISS and ECOG status. Statistical significance of score differences among sub-cohorts was ascertained by ANOVA using SAS 9.1. Results: HRQOL data were reported by 328 pts, enrolled from 135 centers. Pts were predominantly male (60%) and white (79%) with mean age at 67.3 (standard deviation [SD] 11.6) yrs. HRQOL scores by evaluable ISS stage (n=236) and ECOG status (n=258) are presented. BPI data (on a scale of 0 [no pain] to 10 [worst pain]) indicate that average reported pain worsens by ISS and ECOG severity. Mean EQ-5D scores (on a scale of 1 [no problem] to 2 [some problems] to 3 [incapacity]) indicate that pain/discomfort, and usual activities are most compromised, and with self care increase in severity as ISS and ECOG worsen. Anxiety/depression level is associated with ECOG, but not with ISS. FACT-MM results indicate that ISS and ECOG severity is associated with greater decrement in physical and functional domains. The associations of HRQOL with ECOG status were stronger than with ISS stage. Specifically, scores on the BPI, all EQ-5D domains, and all FACT-MM domains (except the social/family domain) were statistically significantly associated with more severe ECOG status. Conclusions: Initial results from the Connect MM® Registry indicate that HRQOL worsens with worsening ISS stage and ECOG status, especially in physical and functioning domains, pain/discomfort, and ability to conduct usual activities and to provide self care. These areas should receive attention at diagnosis. Future analyses should be conducted on: (1) more newly diagnosed patients; (2) how HRQOL may be affected over time with changes in disease; and, (3) how HRQOL may be influenced by alternative therapies. Results reported here should serve as useful baseline reference. Disclosures: Pashos: Celgene Corporation: Membership on an entity's Board of Directors or advisory committees, Research Funding.

Abstract BACKGROUND: Although chemoimmunotherapy (CIT) has improved response rates, treatment free survival, and overall survival in patients with chronic lymphocytic leukemia (CLL), only 40-50% of patients achieve a complete remission and the majority have residual disease when evaluated using sensitive assays. Interactions with nurturing environments can enhance CLL B-cell resistance to apoptosis. These interactions include cytokine mediated prosurvival signals by angiogenic molecules, such as VEGF and bFGF that nurture CLL B-cells in an autocrine fashion and promote CLL cell survival partly through up regulation of anti-apoptotic proteins. These findings provide a strong rationale for testing anti-VEGF therapy in combination with a purine nucleoside analogue CIT regimen for upfront treatment. We conducted a randomized phase 2 CIT trial using pentostatin, cyclophosphamide, and rituximab with (PCR-B) or without (PCR) bevacizumab (B), an anti-VEGF monoclonal anti-body. METHODS: Eligible patients were previously untreated and had CLL in need of treatment by NCI-WG criteria (Blood 111:5446). Patients were randomized using a dynamic allocation procedure stratifying for stage (0-II vs. III-IV) and FISH (17p or 11q deletion vs. other) to receive either 6 cycles of rituximab (100 mg on day 1 of cycle 1; 375 mg/m2on day 2 of cycle 1 and day 1 of cycles 2-6) followed by pentostatin (2 mg/m2) and cyclophosphamide (600 mg/m2) (PCR) administered every 21 days. Patients in the PCR-B cohort also received bevacizumab 15mg/kg on day 1 of cycles 1-5 and days 1, 22, & 43 of cycle 6. All patients underwent complete response evaluation 3 months after day 1 of cycle 6 (or last cycle of treatment for those completing < 6 cycles). MRD was assessed using 6-color flow cytometry (Leukemia 21:956) at the completion of treatment. RESULTS: 68 patients were enrolled through the Mayo Clinic Cancer Research Consortium between 1/2009 and 1/2013. Three patients were excluded from analysis: 1 patient canceled prior to treatment, 1 was dosed incorrectly, and 1 was ineligible due to immunophenotyping inconsistent with CLL. Median age of eligible patients was 63 years (range 43-81) and 43 (66%) were men. With respect to disease stage, 3 (5%), 38 (58%), and 24 (37%) had low, intermediate and high Rai stage disease. Eleven (17%) patients had deletion 17p or 11q & 29 (45%) had unmutated IGHV. No statistically significant differences were observed in these variables by treatment arm. All 65 evaluable patients have completed active treatment, with 54 (83.1%) completing the intended 6 cycles (PCR group 27/32 [84.4%] and PCR-B 27/33 [81.8%]). Hematologic grade 3+ adverse events deemed at least possibly related to treatment were observed in 10 (31.3%) patients on PCR and 12 (36.4%) on PCR-B (p=0.79). Non-hematologic grade 3+ adverse events deemed at least possibly related to treatment were observed in 9 (28.1%) patients on PCR and 18 (54.4%) on PCR-B (p=0.04). The most common such events were hypertension (PCR: 3.1% vs. PCR-B: 21.2%), proteinuria (0% vs. 6.1%) and creatinine increase (3.1% vs. 6.1%). Across both arms, 64/65 (98.5%) patients achieved a response including 31/32 (96.9%) treated with PCR and 33/33 (100%) treated with PCR-B (p=0.49). CR/CRi was achieved in 10/32 (31.3%) patients treated with PCR & 18/33 (54.5%) treated with PCR-B (p=0.08). Of the 28 who achieved a CR/CRi, MRD analysis was completed on 26, of whom 12 (46%) were MRD negative. With respect to treatment arm, 5/32 (16%) patients on PCR and 7/33 (21%) on PCR-B achieved an MRD negative CR. Median time to retreatment for all 65 patients was 44.8 (95% CI: 34.6 – NA) months. Median overall survival has not yet been reached. With current follow-up no differences between treatment-free survival (p=0.38), progression-free survival (p=0.23), or overall survival (p=0.45) are observed by treatment arm. Plasma levels of angiogenic cytokines VEGF, bFGF, thrombospondin (TSP) and the chemokines CCL3 and CCL4 were measured prior to treatment and at the time of the post treatment response evaluation. Correlations of these cytokines with clinical outcome will be presented. CONCLUSION: The addition of bevacizumab to purine analogue-based CIT was generally well-tolerated and may increase complete remission rates in patients with CLL. No clear improvement in treatment free survival has been observed to date.

Abstract Abstract 1530 Background: Maintenance therapy in acute myeloid leukemia (AML) is not standard of care. It has been reported that continued therapy with cytotoxic agents similar to those used for induction and consolidation is associated with toxicity but can improve disease free survival (DFS). Methylation status of tumor suppressor genes in clinical remission may predict the relapse in AML, with earlier relapse in patients with methylated genes. Therefore, hypomethylating therapy may be effective in maintaining remission and prolonging survival. Methods: We have conducted a clinical trial comparing decitabine to conventional care (CC, low dose subcutaneous cytarabine, prolonged intensive therapy, or observation) in patients (pts) with AML in their first or subsequent complete remission (CR). Pts with non-favorable risk AML (including intermediate and poor risk) received induction therapy followed by appropriate consolidation. They were then stratified by age (£ 60 vs. > 60) and cytogenetics (intermediate vs. poor risk) and randomized to receive decitabine 20 mg/m2 IV daily × 5 every 4 to 8 weeks for 12 cycles, or CC. Pts in second or subsequent CR were randomized after completion of salvage therapy. Primary endpoint was considered to be no relapse at 1 year. We also monitored minimal residual disease (MRD) by multicolor flow cytometry (MFC) using custom staining panels based on the leukemic phenotypes. Aberrant myeloid blasts were identified by comparison to normal bone marrow CD34+ cells. Serial samples for DNA methylation studies were also collected and methylation analysis was performed. Results: 50 patients have been enrolled. Of those, 45 (19 M, 26 F) pts (including 35 in first CR and 10 in subsequent CR) were evaluable for the primary endpoint. Median age was 57 years (range, 24–77). 27 pts were £ 60 years and 18 > 60. Cytogenetics at diagnosis was intermediate in 34 pts, poor-risk in 10 pts, and favorable [inv(16)] in one patient in second CR. 20 evaluable pts were randomized to decitabine and have received a median of 4.5 cycles (range 1–12). 25 evaluable pts were randomized to CC. With a median duration of follow up for the entire group of 36.3 months (range 6.3–55), 11 pts on the decitabine arm and 10 pts on the CC arm have remained in remission; 9 of 20 (45%) on DAC versus 15 of 25 (60%) on CC have relapsed (p = 0.7). 45 pts including 20 receiving decitabine and 25 receiving CC have been followed for at least 1 year; 9 of 20 (45%) on decitabine versus 9 of 25 (36%) on CC are alive in CR (p=0.9). Toxicity in the decitabine treated pts was limited to 19 episodes of grade 3/4, neutropenia, 14 episodes of grade 3/4 thrombocytopenia, and 1 episode of grade 2 anemia. All were short in duration and reversed without any associated adverse events. Non-hematological grade 3 and 4 adverse events on the decitabine arm include 3 infections, 1 episode each of hypertension and fatigue. There have been no deaths on the study. MFC identified MRD (<5% blasts on smears) in 9 of 19 (47%) patients with subsequent relapse, at levels from 0.04% to 1% of total cells. In 18 pts remaining in CR, no MRD was identified. Relapse occurred from 1.5 to 10 months after the first positive MFC. There was a statistically significant higher LINE methylation at baseline between the pts who relapsed and those who remained in CR (78% vs 73%, P=0.02), whereas no differences were observed for methylation of CDH13 and Mir124a-1 genes. Conclusions: We conclude that administration of decitabine in CR at the above schedule/dose is well tolerated. The study has been terminated early by the data monitoring safety board due to the higher incidence of relapse at 1 year in the decitabine arm. Interestingly, at a median of 36.3 months, decitabine treated patients had lower relapse and higher survival rates than conventionally treated patients, although these differences were not significant. These data suggest the need for larger randomized studies of hypomethylating agents in maintenance therapy in AML.

Abstract Introduction: T-cell prolymphocytic leukemia (T-PLL) is a very rare & aggressive disease. Therapeutic advances during recent years have been very limited. Even after initial response, the vast majority of T-PLL patients (pts) relapse quickly and the median overall survival remains below 2 years (ys). This also holds true for induction therapies with the anti-CD52 antibody Alemtuzumab (A). Furthermore, life-threatening viral infections are a severe problem in pts treated with this antibody. In a precursor trial (Hopfinger et al, Cancer 2013), we evaluated a consolidation therapy with A after polychemotherapy induction. In the T-PLL2 trial, we evaluated feasibility, safety and efficacy of the addition of A s.c. to an induction treatment with Fludarabine, Mitoxantrone & Cyclophosphamide (A-FMC), followed by an A s.c. maintenance therapy. Patients and Methods: 16 pts (12 untreated and 4 with pretreatments) with T-PLL were enrolled between 06/2010-09/2013. Pts received an induction treatment with A 10mg s.c. on day (d) 1-3 combined with 20mg/m2 Fludarabine i.v. d 1-3, 6mg/m2 Mitoxantrone i.v. d1 & 200mg/m2 Cyclophosphamide d1-3. After 2 cycles the A dose was increased to 30 mg s.c., if a stable disease (SD) or a partial remission (PR) was achieved. A-FMC treatment was administered every 28 days for up to 4 cycles, followed by a maintenance treatment with 30mg A s.c. starting 1 month (mo) after final staging. During the first 6 mo, A s.c. was administered monthly and in addition once in mo 10 and 13. For younger and fit pts, the option of allogeneic transplantation (tx) was explicitly recommended after induction therapy. Peripheral blood (PB) samples were taken at diagnosis & at the time of relapse/progression. Valganciclovir was recommended for prophylaxis. Results: 16 pts with a median age of 68 ys (range 32-78) and a median score on the cumulative illness rating scale of 3 (range 0-6) were enrolled. The diagnosis of T-PLL was established based on clinico-pathologic characteristics, with the lead finding of a monoclonal mature T-cell population in PB. All leukaemias (100%) were CD52 positive, 15/16 cases (93.75%) expressed TCL1 & the most frequent abnormalities by FISH/classical karyotyping were aberrations involving 14q32.1 in 14/14 cases (100%), gains of chromosome 8q in 10/14 cases (71%), & deletion 11q23 in 8/14 cases (57%). A median number of 4 courses (range 2-4) were administered for induction treatment. Six pts (37.5%) proceeded with maintenance treatment with a median of 4 (range 1-6) A applications. In total, 94 non-infectious CTC grade 3-4 adverse events (AE) & 28 episodes of CTC grade 1-4 infections were documented. Non-infectious grade 3/4 AEs were most frequently due to myelosuppression: neutropenia/leukopenia occurred in 14/16 pts (87.5%), anaemia in 7/16 pts (43.75%) & thrombocytopenia in 10/16 pts (62.5%). Two cases of cytomegalovirus (CMV) & 1 case of varicella zoster infection were documented. Most AEs could be successfully managed, however 2 (12.6%), possibly treatment related deaths occurred, both from fatal bleeding in thrombocytopenia. In all pts response data after induction treatment was available. The overall response rate was 68.75% (11/16pts) with complete remissions (CR) in 4 pts (25%), CR with insufficient bone marrow recovery in 1 pt (6.25%) & a PR in 6 pts (37.5%). Progressive disease (PD) was documented in 4 pts (25%), a SD in 1 pt (6.25%). The trial was terminated in May 2014. Until today, 11 deaths (68.75%) were reported & 1 pt (6.25%) was lost to follow-up. Prophylaxis with Valgancyclovir was administered in 12/16 pts (75%), 2 pts (12.5%) received prophylactic Valaciclovir & 2 pts (12.5%) received no viral prophylaxis at all. Seven pts (43.75%) received an allogeneic tx after the study treatment: 3 pts after the induction phase, 1 pt after 5 maintenance applications & 3 pts after bridging/salvage therapy. Tx outcomes were documented with 5 CRs & 2 PDs. Conclusion: A s.c. combined with FMC & A maintenance therapy is a relatively safe and feasible regimen in pts with T-PLL. However, safety seems to come at the cost of response quality. Therefore, the authors currently recommend using A i.v. as part of the initial therapy for T-PLL pts. Prophylaxis with Valganciclovir was effective in preventing CMV infection, one of the major threats to pts treated with A. Most importantly, the study emphasizes the need for new therapies and intensified clinical research for pts with T-PLL.

Abstract Introduction: Myelofibrosis (MF) is a life-threatening hematologic malignancy characterized by splenomegaly and debilitating symptoms including fatigue, abdominal pain, night sweats, bone pain, pruritus, and unintentional weight loss. The myeloproliferative neoplasm symptom assessment form (MPN-SAF) is a PRO tool designed to measure MF-related symptom burden and was developed and validated at Mayo Clinic. It was modified (MPN-SAF total symptom score [TSS] and TSS 2.0) for use in the PERSIST-1 and PERSIST-2 phase 3 trials. For PERSIST-1, when examining the 6 common symptoms in both TSS versions (tiredness, night sweats, early satiety, itchiness, bone pain, and abdominal pain), pacritinib-treated patients (pts) had significant improvements in TSS overall and in individual symptoms vs BAT; Pt Global Impression of Change (PGIC) was also significantly improved for pts receiving pacritinib. Improvements in EORTC-QLQ-C30 scales were noted in the pacritinib arm (Mesa, EHA 2015). The proportion of pts achieving spleen volume reduction (SVR) ≥35% at Week 24 was significantly greater with pacritinib vs BAT (ITT: 19.1% vs 4.7%, p=0.0003; evaluable at baseline and Week 24: 25.0% vs 5.9%; p=0.0001). This analysis examines relationships between TSS improvement and changes in splenomegaly and HRQoL outcomes. Methods: Pts who received no prior JAK inhibitor therapy were randomized 2:1 to oral pacritinib 400 mg once daily or BAT. Pts were stratified by DIPSS risk (Int-1/Int-2 vs High) and platelet count (<50,000/μL vs 50,000/μL to <100,000/μL vs ≥100,000/μL). Pts must have had a baseline total TSS ≥13 using MPN-SAF TSS 2.0. Each symptom is rated on a scale from 0 (absent) to 10 (worst imaginable) using MPN-SAF TSS and TSS 2.0. Results for the 6 symptoms common to both TSS versions are reported. Additional PROs used for assessment of HRQoL included EORTC QLQ-C30 and EQ-5D-5L. In multivariate logistic regressions, odds of TSS reduction ≥50% at Week 24 were modeled as a function of Week 24 SVR ≥35%, spleen length reduction (SLR) ≥ 50%, PGIC, improvement in each EORTC scale, and improvement in EQ-5D-5L Overall Health State (OHS) and in each dimension individually while adjusting for treatment (pacritinib vs BAT). Correlations were examined in all pts and by baseline platelet counts (<50,000/μL, <100,000/μL, and ≥100,000/μL). Results: A total of 327 pts were enrolled (PAC: 220, BAT: 107). 62% of pts had primary MF, 32% had baseline platelets <100,000/μL, and 16% had baseline platelets <50,000/μL. TSS reduction ≥50% was found to be associated with SVR ≥35% and improvement in splenomegaly (SLR ≥50%). In the total pt population, there was a significant association between TSS reduction and SVR (odds ratio [OR]=2.60, p=0.016). In all pts, there was a significant association between TSS reduction and improvements in OHS as measured by EQ-5D-5L (OR=2.30, p=0.013). TSS reductions were also marginally associated with improvements in the QLQ-C30 Global Health Scale (GHS)/QoL Scale (OR=1.92, p=0.050) and, though not statistically significant, there was a trend of improvement in perceived overall health as measured by PGIC (OR=2.16, p=0.118). TSS reductions were further examined in pts grouped by baseline platelet count. Improvement in EQ-5D-5L OHS was marginally associated with TSS reductions in pts with platelets <50,000/μL (OR=6.03, p=0.057). For pts with platelets <100,000/μL, reductions in TSS were significantly associated with reductions in splenomegaly (SLR ≥50%; OR=9.53, p=0.004), and improvements in the QLQ-C30 GHS/QoL domain (OR=4.03, p=0.022) as well as the EQ-5D-5L OHS (OR=5.49, p=0.008). A significant association between TSS reductions and SVR ≥35% was observed in pts with platelets ≥100,000/μL (OR=3.99, p=0.005). In all pts, improvements in Fatigue as measured by QLQ-C30 were significantly associated with TSS reductions (OR=2.20, p=0.019) as well as in pts with baseline platelets <50,000/μL (OR=17.88, p=0.008) and <100,000/μL (OR=10.18, p<0.001). Conclusions: In the total pt population, TSS reduction was associated with improvements in spleen response and perceived overall health. This trend was also observed in pts with low baseline platelet counts. Additionally, TSS reduction was significantly associated with improvements in fatigue, a major contributor to poor HRQoL in pts with MF. This reinforces the clinical relevance of measuring TSS using a validated instrument as an endpoint in MF trials.

Background: Vitamin K antagonists (VKA) have been the main stay of oral anticoagulation (OAC) in pediatrics. However, VKA have multiple challenges. The pharmacological properties of direct oral anticoagulants (DOACs) suggest that they may have advantages particularly for children. The off-label use of DOACs is however on the rise within the pediatric population. The increasingly broad and varied use of DOACs, lack of published clinical guidance, and limited data on reversal strategies have created the imperative to identify strategies for OAC reversal in pediatrics. We conducted an online survey for strategies used for oral anticoagulants reversal in pediatrics. Study Design: Institutional review board approval was obtained and an online survey was developed using the RedCap. The survey was electronically distributed by International Society of Hemostasis and Thrombosis (ISTH) to its Pediatric/Neonatal Thrombosis and Hemostasis Subcommittee group members. The survey questions asked approach to common hypothetical clinical scenarios for OAC reversal.The data were analysed descriptively. Results: There were 76 respondents, majority from academic free-standing Children'sHospitals. Seventy-two percent reported having a hemostasis-thrombosis/anticoagulation service but only 29 % have a dedicated anticoagulation pharmacist. Approximately 40% do not have a formal protocol in place for VKA reversal. For a supra-therapeutic INR (INR > 5) in a non-bleeding patient, 95% opted to manage by omitting the next dose of VKA while 18 % opted to give oral vitamin K alone or comitantly. For clinically relevant non-major bleeding, majority indicated using Vitamin K; oral (51%) or IV (37). For major bleeding on VKA, majority use either a combination of 4F-PCC and IV Vitamin K or plasma and IV Vitamin K (44/76 and 26/76 respectively). The presence of bleeding seemed to be the major driver for the choice of route (enteral versus parenteral) for Vitamin K for VKA reversal. Thirty-six of the 76 respondents indicated using DOACs; 94% used FXa inhibitors and 1/3 use dabigatran in their clinical practice. For non-urgent DOAC reversal, 97% indicated omitting the next dose. For non-major bleeding on DOAC, majority (29/36) indicated omitting the next dose/doses, some chose 4F-PCC (8/36) and only a few indicated use of specific reversal agents (3/36 and 1/36 for Dabigatran and Andexanet respectively). For major bleeding while on DOACs, the use of specific reversal agents (11/35, 6/35 for Andexanet and idarucizumab respectively) followed by 4F-PCC (9/35) was the major intervention indicated. Dilute thrombin time and partial thromboplastin time were the most commonly utilized tests to measure residual dabigatran activity. For Factor Xa inhibitors routine heparin assay rather than DOAC calibrated anti-Xa activity is utilized by most of the responders to assess presence of the plasma drug activity. Conclusion: Practices for oral anticoagulants reversal vary substantially in the pediatric population. Plasma is still used for urgent VKA reversal in many pediatric centers. The off-label use of DOACs in children is on the rise. Our results highlight the need for further studies to standardize OAC reversal in children.

Introduction: The management of immune thrombocytopenia (ITP) in pregnancy can be challenging as some patients either do not respond to or tolerate corticosteroids and intravenous immunoglobulin and only very few alternative ITP therapies are available during pregnancy. The use of thrombopoietin receptor agonists (Tpo-RA) which are likely to cross the placenta is not recommended during pregnancy but both romiplostim and eltrombopag have been exceptionally used to treat women with severe and refractory ITP during pregnancy. To better assess safety and efficacy of Tpo-RA during pregnancy, we performed an international multicentre observational retrospective study. Methods: To be included, the patients had to fulfill the following criteria: pregnant woman aged of 18 years and above, diagnosis of primary or secondary ITP according to international consensus guidelines, use of either eltrombopag of romiplostim for at least 1 week for treating ITP during pregnancy (before delivery), at least a month of follow-up after Tpo-RA initiation. Women who became pregnant while on Tpo-RA could be included even if the treatment was stopped if enough data on pregnancy outcome were available. Women treated with a Tpo-RA during pregnancy not for ITP were excluded. All clinical and biological data were collected by means of a standardized study form, whenever available, data on the neonates were also collected and analyzed. Data are presented as mean±SD or median (interquartile range [IQR]) for continuous variables, depending on their distribution. Categorical variables are presented as number (%). Results: In total, 12 women (mean age at time of pregnancy was 30.3 ± 5 years) fulfilling the eligibility criteria were included, for a total of 13 pregnancies and 14 neonates (one twin pregnancy) with an exposure to Tpo-RA. Nine of 12 patients had pre-existing chronic primary ITP (mean ITP duration = 11.8 ± 10.1 years) whereas ITP was newly-diagnosed during pregnancy in 3 cases. The median number of treatment-lines before the use of Tpo-RA was 3 [range 2-7] including splenectomy for 5 patients. Patients were treated transiently during pregnancy with either eltrombopag (n = 6; mean daily dose 50mg) or romiplostim (n = 6; mean maximal weekly dose 7.4 microg/kg). Two patients with chronic ITP were already on Tpo-RA when pregnancy was confirmed, and for 8 pregnancies, treatment with Tpo-RA was initiated only within 4 weeks before term in preparation for delivery. The median time of exposure to Tpo-RA during pregnancy was 4.4 weeks [range: 1-12 weeks]. No side-effects and especially no thromboembolic events were observed; none of the patients was on thromboprophylaxis. The mean platelet count at term was 91 x 109/L (median = 94 x 109/L [6-250]). Delivery occurred pre-term in 4 out of 13 pregnancies, mode of delivery was vaginal in 8 out of 13 pregnancies (with an epidural in 4 cases) and a C-section in 5. The platelet count was available at birth in 10 out of 13 neonates and neonatal thrombocytopenia was found in 5 (including 3 from the same mother). No case of neonatal thrombocytosis was observed. No neonatal complications attributable to the exposure to a TpoRA in the mother was observed. One neonate (whom the mother received 1 week of romiplostim in preparation for delivery) was diagnosed with trisomy 8 and died on day 7 and another neonate had a pulmonary artery stenosis diagnosed during fetal life (before the initiation or Tpo-RA in the mother), that was successfully operated at 2 weeks of life. A complete platelet response (CR) was achieved on Tpo-RA during pregnancy in 8/12 patients (66%) (5 of them received concomitant ITP therapy), a response (R) in 2 whereas no response was achieved in 2 patients with refractory ITP (table). Conclusion: Based on this preliminary results on a relatively small number of patients (more cases are expected) and taking into account that Tpo-RA was used only in preparation for delivery in 7/13 pregnancies, a temporary off-label use of a Tpo-RA over a short period of time for ITP during pregnancy seems safe for the mother and the neonate. The pattern and magnitude of response seems comparable to what is observed outside pregnancy but only few patients were treated with Tpo-RA alone. For now, the transient use of Tpo-RA during pregnancy should only be considered exceptionally for women with severe and refractory ITP.

Background Despite recent advances, treatment of relapsed refractory multiple myeloma (RRMM) remains a challenge. Venetoclax, a BH3 mimetic, is an oral, specific, and potent small molecule inhibitor of BCL-2 that has been approved for treatment of 17p-deleted CLL and in combination with azacitidine or decitabine in AML patients >/= 75 years of age.Pre-clinical and clinical studies suggest that bcl-2 inhibition can induce MM cell death and may synergize with bortezomib and dexamethasone. Based on this, several prospective clinical trials of venetoclax in RRMM have been performed. However, clinical use of this targeted therapeutic for salvage therapy in RRMM has not been well described. Methods We performed a single-center, retrospective chart review of all patients with RRMM diagnosed after January 1, 2009 who were treated with off-label use of venetoclax. The goal of this study was to describe the clinical characteristics of these patients, assess the response to salvage treatment with venetoclax as determined by the International Myeloma Working Group (IMWG) criteria, and assess the toxicities during salvage treatment with venetoclax in an academic practice setting. Results 43 patients were identified. Median number of lines of prior therapy was 7 (range 2-13). 12 patients had documented high risk cytogenetics, defined as the presence of a 17p deletion, t(14;16), t(14;20), t(4,14), gain (1q), or nonhyperdiploidy. Of the 36 patients with cytogenetics/FISH available, 8 had t(11;14). 34 patients were refractory to bortezomib. 40 patients had progressed after carfilzomib, 36 after pomalidomide, and 41 after anti-CD38 antibody therapy. 39 patients were treated with venetoclax in combination with a proteasome inhibitor (bortezomib (n=36); carfilzomib (n=3)). 23 patients were treated with venetoclax, proteasome inhibitor, and dexamethasone. Patients were started at 400 mg daily for 7 days then increased to the median dose of 800mg daily (11 received < 800mg/daily as a final dose and one received >800 mg/daily as final dose). Overall patients were on treatment for a median of 67 days (range 2-855). 2 patients received intermittent venetoclax therapy, defined as being off venetoclax for at least 3 months before restarting. Best response by IMWG criteria include; CR 5%( 2/43), VGPR 12% (5/43) and PR 16% (7/43) for an overall response rate of 33% (14/43). In addition, MR was seen in 5% (2/43) and stable disease in 9% (4/43). Fifty-one percent (22/43) had progressive disease (PD). Out of the 8 patients who had t(11;14), best responses were: 2 VGPR, 2 PR, 1 SD, and 3 PD for a response rate of 50% (4/8) in this subgroup. Median time to best response for all responding patients was 90 days (range 15-305) and median duration of response was 206 days (range 28-820). At time of data collection, median follow-up time from venetoclax treatment initiation was 192 days (range 8-1058). Four patients have not progressed and remain on therapy, 23 patients remain alive, and 4 patients have been lost to follow-up for over 6 months. The most common treatment related AEs were cytopenias including leukopenia in 26 /43 (60%) patients, neutropenia in 19/43 (44%) patients, and thrombocytopenia in 22/43 (51%) patients. Non-hematologic toxicities included diarrhea in 12/43 (30%) patients, nausea/vomiting in 15/43 (35%) patients, infections in 11/43 (26%) patients, and fatigue in 23/43 (53%) patients. 8/43 (19%) patients required dose reduction, 7/43 (16%) patients required temporary discontinuation of treatment, and 4/43 (9%) patients required permanent discontinuation due to treatment related AEs. 38/43 (88%) patients had any grade treatment related AEs, 27/43 (63%) patients had grade >/= 3 AEs and 2/43 (5%) patients had treatment related SAEs. One patient had a treatment related death from an infectious complication (CMV pneumonitis). Conclusions Venetoclax is an active and well-tolerated agent in relapsed multiple myeloma. Furthermore, it is easily administered in the outpatient setting. Additional areas of research with this therapy include understanding the importance of t(11:14) for response and selecting the best anti-MM partner for combination therapy.

Abstract Background: Autologous stem cell transplantation (ASCT) improves outcome in comparison with chemotherapy (CC) innewly diagnosed multiple myeloma (NDMM) patients. The primary objective of our analysis was to compare progression-free survival (PFS) and overall survival (OS) of patients randomized to ASCT vs. chemotherapy (CC): we tested the hypothesis that benefit of ASCT could vary in different subsets of patients defined according to baseline prognostic features and response to induction. Methods: Data of 2 phase III multicenter randomized trials (RV-MM-PI-209 and RV-MM-EMN-441) enrolling patients younger than 65 years were pooled together. In both trials, patients received lenalidomide-dexamethasone induction and stem cell mobilization. Patients were randomized to either consolidation with 2 courses of Melphalan 200 mg/mq followed by ASCT (Mel200-ASCT) or 6 cycles of CC plus lenalidomide (CC+R) (RV-MM-PI-209: melphalan-prednisone-lenalidomide; RV-MM-EMN-441: cyclophosphamide-dexamethasone-lenalidomide). We evaluated PFS and OS of Mel200-ASCT vs. CC+R patients in the following subgroups, defined according to baseline features (Karnofsky performance status (PS) [60-70%, 80-100%], International Staging System (ISS) stage [I, II, III], cytogenetic profile [presence of del17 or t(4;14) or t(14;16); absence of del17, t(4;14) and t(14;16)]) and response to induction (≥very good partial response [VGPR], <VGPR). Data cut-off was June, 2014. Results: 791 patients were enrolled in the two trials; 529 were eligible for consolidation: 268 patients received Mel200-ASCT and 261 patients received CC+R. Median follow-up for survivors was 4 years. Mel200-ASCT significantly prolonged PFS (median: 42 vs. 24 months, HR 0.52, 95%CI 0.41-0.65, P<0.001) and OS (4-year: 83% vs. 68%, HR 0.59, 95%CI 0.40-0.90 P=0.012) in comparison with CC+R. Mel200-ASCT significantly improved PFS in all the subgroups of patients analyzed. (Table). The most significant OS benefit was noticed in patients with a Karnofsky PS 80-100% (4-year: 85% vs. 73%, HR 0.55, 95% CI 0.35-0.88, P=0.013), with ISS Stage I disease (4-year: OS 89% vs. 77%, HR 0.43, 95% CI 0.20-0.91, P=0.027), with absence of del17, t(4;14) and t(14;16) (4-year: 87% vs. 78%, HR 0.57, 0.33-0.98, P=0.040), and in patients achieving ≥VGPR after lenalidomide-dexamethasone induction (4-year: 84% vs. 65%, HR 0.46, 95% CI 0.22-0.96, P=0.039). Conclusions: In NDMM patients, Mel200-ASCT significantly improved PFS and OS in comparison with CC+R. The most significant OS advantage was observed in patients with baseline Karnofsky PS 80-100%, ISS Stage I, with absence of del17, t(4;14) or t(14;16) and in patients achieving ≥VGPR after induction. These data suggest intensifying treatment in good-prognosis patients and in patients with a chemo-sensitive disease. More effective novel agents are needed for patients with a more aggressive disease.
