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 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 Background: The Philadelphia-negative, chronic myeloproliferative neoplasms (MPN) include essential thrombocythemia (ET), polycythemia vera (PV) and primary myelofibrosis (MF) (PMF). Chronic inflammation and a deregulated immune system are considered important for clonal evolution and disease progression. Ruxolitinib is a potent anti-inflammatory agent and has shown great benefit in MPN patients (pts), reducing spleen size and inflammation-mediated symptoms, thereby improving quality of life (QoL). Interferon-alpha2 (IFNa2) has been used successfully for decades in the treatment of MPN. However, 10-20% of pts are intolerant to IFNa2, yet others show limited response. Since concurrent inflammation might attenuate the efficacy of IFNa2 therapy, a combination therapy (CT) with the two agents may be more efficacious than monotherapy, likely reducing the inflammation-mediated adverse effects of IFNa2 as well. The purpose of this COMBI-trial is to evaluate the safety and efficacy of CT with IFNa2 and ruxolitinib. Patients and Methods: At the time of data cutoff, a total of 30 pts ≥18 years with prefibrotic or hyperproliferative PMF (n=7), PV (n=20) or post-PV MF (PPV-MF) (n=3) with or without prior treatment with IFNa2 and without serious comorbidity were enrolled. Evidence of active disease was required. Initial therapy was IFNa2 45 μg x 1 sc/week (Pegasys®) or 35 μg x 1 sc/week (PegIntron®) + ruxolitinib (Jakavi®) 20 mg x 2/day. Efficacy was evaluated by internationally accepted clinicohematological response criteria, with the modification that splenomegaly was assessed by palpation instead of imaging, by week 2 and 1, 3, 6 and 9 months. In addition, JAK2V617F-allele burden was monitored. Adverse events (AE) including serious AE (SAE) were recorded. Results: Median treatment duration was 24.4 weeks (range, 3.4 weeks-43.3 weeks). Twenty-seven pts were previously treated with IFNa2 (n=18 intolerant, n=5 unresponsive, n=4 both). Three pts were treatment-naïve. Twenty-seven pts (90%) remained on CT; 3 pts discontinued treatment due to an AE. One patient died from transformation to AML shortly after initiation of CT and was not included in this interim analysis. Marked improvements in pruritus, night sweats, and fatigue were recorded within the first 2-3 days in the large majority of pts and in all within 4 weeks. Palpable splenomegaly in 7 pts at baseline was significantly reduced by week 2. Hct control without phlebotomy was achieved by week 4 in 78 % of pts (7 of 9), who at baseline had an elevated hct. Only 3 pts required a total of 3 phlebotomies after initiation of CT. In Figure 1 median hct levels at 0, 1, 3, 6 months are shown. Overall, complete response (CR) was achieved as best response in 19 pts (63.3%) and partial response (PR) or major response in 8 pts (26.7%). Only 3 pts (10%) had no response (NR) to treatment. Among PV pts, 15 (75%) achieved CR (week 2, n=6; 1 month, n=6; 3 months, n=3). The other 5 PV pts achieved PR (week 2, n=3; 1 month, n=2). In PMF pts, CR (n=2) or major response (n=2) was achieved in 4 pts (57.1%) by week 2 or 1 month, and NR in 3 pts (42.8%). Among PPV-MF pts, 2 pts (66.7%) achieved CR and 1 patient (33,3%) PR by week 2. Furthermore, JAK2V617F% declined significantly as depicted in Figure 2 (JAK2V617F% over time for each patient) and 3 (median JAK2V617F% at 0, 3, 6 months). Anemia (n=15, 2 grade 3), granulocytopenia (n=13, 2 grade 3) or thrombocytopenia (n=6, 1 grade 3) were the most common AEs and were managed by dose reduction. One patient with PPV-MF (leuko- and thrombocytosis) developed pancytopenia within the first 2 weeks on CT, necessitating pausing medication for > 2 weeks. Eleven SAEs requiring hospitalization were recorded in 9 pts: pneumonia (n=3), fever (n=2), lipotymia, hematemesis, phlebitis, herpes zoster, angina pectoris and arterial hypertension, 1 patient each. Conclusion: CT with IFNa2 and ruxolitinib is highly efficacious and safein pts with PV or hyperproliferative MF,who were unresponsive or intolerant to monotherapy with IFNa2. Complete clinicohematological responses were achieved in the majority of pts in concert with a reduction in the JAK2V617F-allele burden. In general, the treatment was well tolerated. The preliminary results from this study are highly promising, encouraging a prospective study with CT in newly diagnosed pts. Additional follow-up data will be presented including QoL assessment and the impact of concurrent treatment with statins. Figure 1. Figure 1. Figure 2. Figure 2. Figure 3. Figure 3.

Abstract Abstract 3898 Background: Although chemoimmunotherapy (CIT) has substantially improved response rates, treatment free survival, and overall survival in patients with chronic lymphocytic leukemia (CLL), only 4050 of patients achieve a complete remission and the majority have residual disease when evaluated using sensitive assays. There remains interest in identifying new approaches to improve the effectiveness of CIT. Ofatumumab is a humanized anti-CD20 monoclonal antibody that is approved for patients with relapsed CLL refractory to fludarabine and alemtuzumab. The single agent activity of ofatumumab in patients with refractory CLL suggests it may have greater efficacy than rituximab in patients with CLL. To explore the efficacy of ofatumumab based CIT, we initiated a clinical trial studying the effect of ofatumumab in combination with pentostatin and cyclophosphamide (PCO) for patients with previously untreated CLL. METHODS: Eligible patients were previously untreated and had CLL in need of treatment according to the NCI-WG criteria (Blood 111:5446). The treatment schema included 6 cycles of ofatumuamb (300 mg on day 1 of cycle 1;1000 mg on day 2 of cycle 1 and day 1 of cycles 26) followed by pentostatin (2 mg/m2) and cyclophosphamide (600 mg/m2) administered every 21 days. All patients underwent complete response evaluation including evaluation for MRD using sensitive flow cytometry (Leukemia 21:956) at the completion of treatment. RESULTS: 33 patients were enrolled at Mayo Clinic and Duke University between 3/2010 and 9/2010. All patients were eligible for treatment and have completed active treatment. Clinical characteristics included: 76 male, median age 63 (range: 5083); intermediate Rai risk 27; and high Rai risk 73. On prognostic testing 33 were CD38, 48 Zap-70 , 58 IGHV unmutated, and 6 had high risk FISH (del 17p13; del 11q22). 26 of 33 eligible patients (79) completed all 6 cycles of PCO induction. Seven patients went off treatment early (toxicity: n5; refusal: n1; progression: n1). Adverse events deemed at least possibly related to PCO induction included 8 (24) patients with grade 3 hematologic toxicity and 5 (15) with grade 3 non-hematologic toxicity. The overall response rate to PCO induction was 94 (31/33) with 15 (45) CR/CRi, 5 (15) CCR, 9 (27) nPR, and 2 (6) PR. 2/10 (20) patients with CR's tested for MRD were also MRD negative by 6 color flow cytometry analysis. Finally, we compared this cohort of patients treated with ofatumuamb-based CIT to our prior 108 patient cohort of patients treated with rituximab-based CIT both of which used an identical chemotherapy backbone (pentostatin and cyclophosphamide). Although the age, gender, ALC, and prognostic profile (CD38, ZAP-70, and IGHV mutation status) of treated patients were similar (all p0.3), the ofatumumab cohort included more advanced stage patients (Rai stage III/IV: 73 vs. 41 p0.002). Ofatumumab-based CIT appeared to be better tolerated than our previous experience with rituximab-based CIT (grade 3 hematologic toxicity ofatumumab-CIT 24 \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \({\scriptstyle \raisebox{1ex}{8$}\!\left/ \!\raisebox{-1ex}{$33$}\right.}\]\) \end{document} vs. rituximab-CIT51 \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \({\scriptstyle \raisebox{1ex}{55$}\!\left/ \!\raisebox{-1ex}{$108$}\right.}\]\) \end{document}, p0.009; grade 3 non-hematologic toxicity ofatumumab-CIT 15 \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \({\scriptstyle \raisebox{1ex}{5$}\!\left/ \!\raisebox{-1ex}{$33$}\right.}\]\) \end{document} vs. rituximab-CIT 24 \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \({\scriptstyle \raisebox{1ex}{26$}\!\left/ \!\raisebox{-1ex}{$108$}\right.}\]\) \end{document}, p0.34). Despite a higher proportion of Rai Stage III/IV patients in the ofatumumab cohort, the efficacy of ofatumumab-based CIT also compared favorably to our previous experience with rituximab based CIT (Table). CONCLUSION: Front-line ofatumumab-based CIT appears to be well-tolerated in patients with CLL. Compared to our historic experience with rituximab based CIT, ofatumumab-based CIT appeared to have less hematologic toxicity and improved efficacy. This trial has been expanded to provide a larger experience with ofatumumab-based CIT.

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

Abstract Background: Ruxolitinib (RUX), a JAK1/JAK2 inhibitor, and venetoclax (VEN), a BCL-2 inhibitor are 2 drug candidates recently identified as promising candidate for the treatment of T-Cell prolymphocytic leukemia (T-PLL). We recently reported that JAK/STAT pathway inhibition with RUX enhances BCL-2 dependence, thereby sensitizing T-PLL cells to VEN (Herbaux et al., Blood, 2021). We also showed that JAK/STAT pathway mutational status could impact RUX activity. Here, we report results on the 15 first patients who were treated with RUX and VEN oral combination for T-PLL. All patients were refractory to, or ineligible for alemtuzumab, the principal therapeutic option to date. Methods: In this multicenter retrospective study from the French Innovative Leukemia Organization, 15 patients with T-PLL (according to consensus criteria) were included. All patients were informed about the off-label use of this combination and provided informed consent. Patients received a maximum dose of RUX 15 mg twice daily, and VEN 800 mg daily. VEN was started with daily ramp-up from 20 mg to 800 mg over 6 days, with TLS prophylaxis (rasburicase and IV hydration). Responses were assessed by consensus criteria. Next generation sequencing (NGS) was performed using a custom-designed panel of 33 genes, including among others: ATM, TP53, IL2R, JAK1, JAK3, and STAT5B. CytoScan HD microarray (Affymetrix) were used to study copy number variation and or uniparental disomy. In vivo dynamic BH3 profiling (DBP) was performed on samples obtained from two patients on treatment. Results: All 15 patients were refractory or relapsing after chemotherapy (mostly bendamustine and pentostatin), except one. They were either refractory to (n=10) or ineligible (n=5) for alemtuzumab (ineligibility was decided by the treating physician based on age and comorbidities). The median age was 70 years (48-88). Within a week of starting RUX, a transient increase of the absolute lymphocyte count was observed in 66.6% of the patients. Based on the molecular status of the JAK/STAT pathway, we established 2 groups of patients. One with samples where no mutations were found (WT, n=3), and one with at least one mutation in the JAK/STAT pathway (MUT, n=12). The overall response rate (ORR) was 73.3%, with only partial responses. Five patients nearly fulfilled CR criteria except that they had persistent lymphocytosis (over 4 x 10 9/L), all of them were in the MUT group. ORR was 83.3% in the MUT group, and only one patient of the WT group obtained a PR. With a median follow-up of 73 days (22 to 368), the median progression free survival was significantly shorter in the WT group in comparison to the MUT group (1.8 months versus 5.6 months, p=0.04, Figure). Of note, four patients were treated with VEN monotherapy before the start of the combination with RUX. With that treatment, 3 of these patients achieved stable disease followed by progression within 2 to 3 months, while 1 was primary refractory to VEN monotherapy. The most frequent reported adverse events (AEs) of the RUX plus VEN combination were cytopenias, with 46.6% grade 3 or 4 thrombocytopenia and 40% grade 3 or 4 neutropenia. DBP showed that overall priming and BCL2 dependence increased in vivo (n=2) during the treatment with RUX and VEN. Finally, SNP arrays identified clonal evolution in the 3 patients evaluated sequentially (before treatment versus at progression). In one case, emergence of EZH2 and JAK1 mutation was also observed at progression using NGS. Conclusions: These preliminary results suggest promising activity of RUX plus VEN in T-PLL, and justify the development of a prospective clinical trial of this combination. Our data seem to show that this combination may be especially active for patients with JAK/STAT pathway activating mutations and that disease progression is associated with clonal evolution. Updated results will be presented at the meeting. Figure 1 Figure 1.

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 Introduction The LenaMain study is a prospective, randomized, open label, multicenter phase III trial which included 188 patients 3 months after first-line high dose treatment and autologous stem cell transplantation (NCT number: NCT00891384). Patients were equally randomized to receive either 25 (n = 94, arm A) or 5 mg (n = 94, arm B) lenalidomide maintenance until disease progression following a uniform 6 months of 25 mg lenalidomide consolidation. Final analysis after follow-up of 46.7 months was presented at ASCO 2018 (#8016) demonstrating an extended event-free survival for arm A (11.8 months, p=0.032) and an about 10% increase of grade 3/4 infections per year as main toxicity. Here we report analysis of quality of life (QoL) data as secondary endpoint of the study. Materials & Methods The EORTC Quality of Life Questionnaire C30 (QLQ-C30) was collected at baseline and then monthly at every new cycle. The Global Health Status/Quality of Life (GHS/QoL) scale, the utility score and seven subscales (fatigue, nausea and vomiting, pain, physical functioning, role functioning, disease symptoms, and adverse effects of treatment) were compared between groups using a mixed model for repeated measures. Results Baseline questionnaire compliance was excellent (95.7%) and declined over time (82%, 76%, 71%, 54%, 49% after consolidation and after year 1, 2, 3 and 4 of maintenance, respectively). At baseline, GHS/QoL (67/67) and utility (0.73/0.72) scores for arm A/B were generally high and did not differ between both arms. The median GHS/QoL change between consolidation baseline and maintenance baseline was -1%. GHS/QoL scores appear constant for both treatment arms at most time points in the first 2 years of maintenance. Relevant improvements ≥ 5 points were observed in 30% of patients while improvements ≥ 15 points were observed in 20% of patients. During the same time a similar percentage of patients had relevant ≥ 5 and ≥15 point deteriorations, with a general tendency for a slight increase at the end of year 2. Notably, a greater number of deteriorations was found in the 5 mg lenalidomide arm. Mean GHS/QoL was constant during maintenance with a slight decrease of <2 over the 1st year, reaching borderline relevance after the 2nd year with a mean change of -6 which was mainly driven by the 5 mg lenalidomide treatment arm (25 mg arm: -4 vs. 5 mg arm: -8). Utility values remained constant during maintenance (change from baseline 0.003, p=0.9 at year 1; 0.02, p=0.7 at year 2) and the overall pattern in the change over time does not appear to show any clear differences between the two treatment arms. Looking at QLQ-C30 subgroup domains after two years of maintenance, we observed a significantly higher change from baseline for diarrhea in the 25 mg lenalidomide arm, which may be a long-term drug-related effect. Conversely, role functioning was also significantly better in patients treated within the 25 mg lenalidomide arm. Other subgroups did not show significant differences after the second year. Overall GHS/QOL scores were not significantly different in patients with CR vs. ≥ vgPR. Similarly, there was no statistical difference in patients on treatment for 1, 2, 3 or 4 years of maintenance or in patients suffering from grade 3/4 adverse events or not. Thus, neither disease activity, nor duration of treatment nor high-grade toxicity biased our results. Conclusion The LenaMain trial shows that maintenance treatment with 25 mg lenalidomide vs. 5 mg significantly prolongs event-free survival. QoL, as secondary objective, was not different between both treatment arms, even showing a trend for improved QoL in the 25 mg lenalidomide treatment arm. Thus, QoL was not governed by the higher rate of infectious toxicity during high-dose lenalidomide maintenance.

Background: Fever is a cardinal symptom of cytokine release syndrome (CRS) after CAR T-cell therapy with 84% of patients experiencing fever on the ZUMA-1 trial of axicabtagene ciloleucel (axi-cel). Knowledge of the patterns of fever and associated symptoms may inform the clinical management of these patients. Methods: We performed a single center retrospective study in 78 patients receiving axi-cel for large B cell lymphoma (LBCL) as of 12/31/2018. We evaluated all the patients who developed fever during lymphodepleting chemotherapy with fludarabine (Flu) and cyclophosphamide (Cy), after CAR T-cell infusion, and after administration of tocilizumab (toci); and analyzed the association of fever with toxicity rates (grade 3+ CRS and neurotoxicity) and efficacy [overall response rates (ORR) and complete response (CR) rate 6 months post CAR T-cell infusion]. Fever was defined per the Lee criteria [equal to or greater than 38 °C], CRS used the modified Lee criteria and neurotoxicity used the CARTOX grading system. Results: Fever occurred in 71/78 (91%) of patients. Rates of grade 3+ CRS and neurotoxicity were 9% (7/78) and 26% (20/78) respectively. The CR rate at 6 months was 41% (32/78). Toxicities and outcomes in patients with the described fever characteristics are shown in the Table. During lymphodepletion with Flu/Cy, fever was observed in 11% (9/78) of patients. Fever occurred within 24 hours of axi-cel infusion in 47% (37/78) and within 72 hours of axi-cel infusion in 71% (55/78) of the patients. In total, 41% (32/78) of patients were treated with anti-IL6R therapy (tocilizumab; toci) for CAR T toxicity. After the first dose of toci, fever recurred in 69% of patients (22/32), of which 34% (11/32) experienced fever recurrence within 24 hours of toci infusion. Conclusions: This is the first study to our knowledge that describes in detail the characteristics of fever after CAR T-cell therapy with axi-cel. Fever was common and occurred in 71% of the patients within 72 hours of axi-cel infusion. When toci was used, fever recurred in a majority of patients (69%) and in 1/3 of patients the fever recurred within 24 hours of toci infusion. These descriptive data may be used by clinicians to inform their expectations of fever occurring after treatment with axi-cel and/or toci. Table Disclosures Bachmeier: Kite/Gilead: Speakers Bureau.

Abstract Abstract 2823 Background: Cutaneous lymphomas consist of a heterogeneous group of diseases that are characterized by a clonal accumulation of lymphocytes in the skin. The estimated incidence is 1–2/100.000 per year. The more advanced stages have a poor prognosis and treatments are usually palliative, such as combination of PUVA with retinoids or recombinant interferon alpha. CHOP or COPBLAM are widely used in analogy to other peripheral T-cell lymphomas, but have severe, sometimes lethal infectious complications and short response duration. Some studies indicated response rates after CHOP chemotherapy regimen are between 40% and 70% in cutaneous T-cell lymphoma (CTCL). However, these studies include patients in various disease stages, that might not necessarily need aggressive treatment and without precise information concerning the CTCL subtype. Therefore, there is an urgent need for multicenter trials designed to test a clearly defined patient population. Pegylated liposomal doxorubicin (PLD, Caelyx™) is an antineoplastic antibiotic with pharmacologic actions similar to those of daunorubicin. PLD provides a longer circulation time and a higher drug concentration in tumors than in normal tissue that could lead to reduced side effects in particular life-threatening cardiotoxicity and neutropenia with infectious complications. Material and methods: Eligible patients had histologically confirmed Mycosis Fungoides stage IIb, IVa, or IVb, WHO performance status (PS) 0–2, no systemic treatment with steroids and refractory or recurrent disease after at least 2 or more previous therapies. Caelyx 20 mg/m2 was administered on days 1 and 15 in a 28-day cycle for a maximum of 6 cycles. The primary endpoint was response rate (RR), defined as patients achieved either complete clinical response (CCR) or partial response (PR). Using the Fleming design with α= 0.1 and β= 0.05 and aiming at a RR = 45% and powered to rule out a RR < 25%, 48 patients who are eligible and started treatment are required. To declare success, a 1-sided 90% confidence interval (CI) for RR should exclude 25% (the rate used in the null hypothesis). Results: Between November 22, 2003 and July 3, 2009, 9 centers registered 49 patients. All of them were eligible and started treatment. The majority of patients were male (67%), had PS 0, 1 (43%, 53%) and were between 56–65 and 66–75 year old (33% and 31%). The median (range) number of chemotherapy cycles received was 5(1-6) and the majority of patients had relative dose intensity of 90–110% and 70–90% (53% and 35%). Eighty eight percents of patients received prophylactic antiemetics; 84% had PS 0–1 during treatment. There was no Grade 3–4 hematological toxicity; only grade 2 neutropenia (4%), leukopenia (4%) and anemia (4%) were observed during treatment. Grade 3/4 non-hematologic/non biochemical toxicities were cardiac (2%), allergy (2%), constitutional symptom (4%), hand foot reaction (2%), other dermatologic toxicity (6%), other gastro intestinal toxicity (4%) and other infection (4%). One patient (2%) had grade 4 cardiac ischemia. Of 49 patients who were eligible and started treatment, 20 (40.8%) were responders: 3 (6.1%) CCR and 17 (34.7%). The 1-sided 90% CI for the RR is: (31.2%, 100%). Conclusion: The primary RR endpoint of the study was reached (ie, 1-sided 90% CI excludes 25%). We conclude that Caelyx™ should be considered for further investigation. Caelyx™ has an acceptable safety profile with only a few toxicities and no sepsis observed in this patient population of advanced age. Its efficacy appears promising.

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.
