Abstract: The Bruton tyrosine kinase inhibitor ibrutinib (IB) has attained an important role in the treatment of patients with chronic lymphocytic leukaemia, mantle cell lymphoma, and Waldenström macroglobulinemia, significantly improving clinical outcomes. However, IB therapy has been associated with an increased risk of atrial fibrillation (AF) and bleeding. We report on the expert opinion that a group of Italian haematologists, cardiologists, and pharmacologists jointly released to improve the practical management of patients at risk for AF and bleeding during treatment with IB. A proper pretreatment assessment to identify patients who are at a higher risk, careful choice of concomitant drugs, regular monitoring, and multispecialist approach were characterized as the main principles of clinical management of these patients. For patients developing AF, anticoagulant and antiarrhythmic therapy must be guided by considerations about efficacy, safety, and risk of pharmacokinetic interactions with IB. For patients experiencing bleeding or requiring procedures that increase the risk of bleeding, considerations about platelet turnover, IB‐related platelet dysfunctions, and bleeding worsening by concomitant anticoagulants or antiplatelet agents provide clues to manage bleeding. Overall, AF and bleeding are manageable clinical events in patients receiving IB, not requiring drug interruption in most cases. Preexisting AF should not represent an absolute contraindication to IB therapy. For each patient candidate for IB, strategies of risk assessment and mitigation may allow to exploit the life‐saving effects of in chronic lymphocytic leukaemia and mantle cell lymphoma.

Abstract: Introduction. The fludarabine, cyclophosphamide, rituximab (FCR) regimen is associated with high complete response (CR) rates and a negative residual disease status in a significant proportion of cases and is considered the optimal front-line treatment for fit patients with chronic lymphocytic leukemia (CLL). In addition, long-term follow-up of patients treated with FCR at the MD Anderson Cancer Center, in the multicenter German CLL8 study and at Italian institutions indicate that a sizable fraction of patients characterized by a favorable biologic profile remains free from progression in excess of 10 years. FC combined with ofatumumab (FC-O), a human monoclonal antibody which targets an epitope of the CD20 molecule, has also been associated with a high CR rate. The aim of this study was to evaluate whether a double dose of ofatumumab (O2) combined with FC could improve the CR rate in young (≤65 yrs) and fit patients with CLL. Methods. Sixty-one fit CLL patients from 15 Italian institutions were enrolled in this front-line study and treated with the FC-O2 regimen based on the FC schedule (F 25 mg/sqm i.v. d1-3, C 250 mg/sqm i.v. d1-3) combined with 13 doses of O (300 mg i.v. d14; 1000 mg d21 at the first cycle; 1000 mg d1 and d15 at cycles 2-6 and d28 at cycle 6). As infection prophylaxis, patients received bactrim and peg-filgrastim in order to prevent granulocytopenia. CLL diagnosis, treatment requirement and response were assessed according to the 2008 iwCLL guidelines. Minimal residual disease (MRD) was evaluated by flow cytometry in the peripheral blood (PB) and bone marrow (BM), and also by RQ-PCR in flow negative cases. CT scan evaluation was included in the response assessment. Adverse events (AEs) were graded according to the NCI-CTCAE. Results. The median age of patients was 60 years (range 36-65), Binet stages B and C were recorded in 86% of cases, B-symptoms in 21%, increased β2M values in 74% and bulky nodes (≥5 cm) in 10%. An IGVH unmutated status was recorded in 60% of cases, deletion 13q in 37%, no aberrations in 33%, deletion 11q in 14%, trisomy 12 in 12%, 17p deletion and/or TP53 mutation were found in 10% of cases. At present, the median follow-up of patients is 7 months (range 1-20). Response to treatment has been assessed in 29 patients after a median number of 6 courses of treatment (range 2-6). The overall response rate is 90%, with a CR rate of 69% (20 patients). No evidence of MRD was observed by flow cytometry in both PB and BM in 15/20 CR patients (75%). To date, 11 patients with cytometric MRD negative CR have been evaluated by RQ-PCR and no residual disease was detected in 3. Grade 3-4 granulocytopenia was recorded in 4 patients (7%), a severe infection in 4 (7%) and 5 patients (8%) experienced a severe infusion-related reaction during ofatumumab administration. Treatment was discontinued in 8 patients as a result of toxicity (infection, 2 cases; FUO, 1; infusion-related toxicity, 1; autoimmune hemolytic anemia, 1; recurrent granulocytopenia, 1; tachyarrhythmia, 1; non-specified toxicity,1). A non-treatment-related death (traumatic aortic transaction due to a dislocated aortic endoprostheses) has been recorded in a patient after 2 months from treatment discontinuation and 1 showed a disease progression after 4 courses of FC-O2. Conclusions. Taken together, the first analysis of this ongoing front-line study suggests that the combination of FC with an increased dose of ofatumumab is well tolerated with acceptable and no unexpected toxicity. Our preliminary results show that the FC-O2 treatment is associated with a high rate of cytometric MRD-negative CR in young and fit patients with previously untreated CLL.

Abstract: Because tumor progression is angiogenesis-dependent, angiogenesis density was investigated by immunohistochemistry and computed image analysis in bone marrow (BM) biopsies of 45 newly diagnosed patients with Binet stage A B-cell chronic lymphocytic leukemia (BCLL) and correlated to upstaging and progression-free survival during a 40-month follow-up period. Their microvessel areas and counts were significantly higher than those of patients with anemia due to iron or vitamin B12deficiencies. A cutoff value of 0.90 mm2 × 10−2 or greater of the microvessel area identified patients with earlier upstaging and shorter progression-free survival. When the cutoff was applied to the Rai subclassification, both Rai 0 and Rai I-II patients who upstaged and shortened the progression-free survival were classified correctly. Information of this type was not given by the microvessel counts. The cutoff did not correlate with other predictors representative of tumor mass or disease progression. The microvessel area correlated with the expression of angiogenic vascular endothelial growth factor (VEGF) by tumor tissue, and serum levels of VEGF were found to be of prognostic value. A causal relationship between risk of progression and BM angiogenesis in BCLL is suggested. A risk stratification inside Rai is proposed. The prognostic usefulness of BM angiogenesis in patients with BCLL is envisaged.

Abstract: Introduction. Observational, real-life studies are relevant to understand whether data derived from prospective controlled trials (CTs) are reproducible in the day-to-day clinical practice. Within a named patient program (NPP), free and early access to ibrutinib was made available for the treatment of relapsed/refractory (R/R) patients with chronic lymphocytic leukemia (CLL) until this agent was approved in Italy. To define the efficacy and toxicity profile of patients treated with ibrutinib in this real-life setting, the GIMEMA (Gruppo Italiano Malattie EMatologiche dell'Adulto) group carried out a retrospective analysis on the outcome of R/R patients with CLL who received ibrutinib in the NPP. Methods. Between April 2014 and January 2015, 216 R/R patients with CLL managed at 20 centers in Italy were included in the NPP. Patients were required to have R/R disease with disease progression within 24 months after prior chemo-immunotherapy. All patients received ibrutinib at the standard dose of 420 mg daily, continuously until disease progression or unacceptable toxicity. The period of observation included the duration of the NPP and was extended up to January 2016 for patients still on treatment with the commercial drug. Clinical data were reported retrospectively by the treating physicians using the Research Electronic Data Capture (REDCap) system. Results. The median age of patients was 58.3 years (range 27.5-81); 89% of patients were in Binet stage B-C. The median number of prior treatments was 3 (range 1-14). Thirty-seven % of patients was refractory to prior treatment. Deletion 17p and/or TP53 mutations were found in 54% of patients and deletion 11q in 11.6%. Seventy-eight % of patients had an unmutated IGHV gene profile. Prior atrial fibrillation (AF) was reported in 13 cases (6%), while 7 patients with AF (3.3%) were on anti-arrythmic treatment. Hypertension was recorded in 76 cases (35.2%). The median follow-up of patients was 24 months (range, 1-24 months. A response to ibrutinib was observed in 172 patients (79.6%) with a clinical CR/CRi in 34 (15.7%) and a PR/PR-L in 138 (63.9%). Similar response rates were observed in patients with an unmutated IGHV gene status (82.1%) and in those with deletion 17p/TP53 mutations (79.6%). The progression-free survival (PFS) and overall survival (OS) at 24 months were 64.6% (95%CI: 58.0-71.9) and 72.7% (95%CI: 66.5-79.4), respectively. No differences in PFS and OS were observed according to the IGHV mutational status (IGHV unmutated vs mutated: PFS, 65.2% vs 61.0%; p=0.7; OS, 65.2% vs 72.0%, p=0.6) and the presence of TP53 aberrations (TP53 aberrations, present vs absent: PFS, 64.8% vs 64.1%; p=0.6; OS, 69.8% vs 72.7%; p=0.8). Forty-eight patients (22.2%) discontinued ibrutinib within 12 months and 22 (10.2%) within 12-24 months from the start of ibrutinib. Progressive disease and Richter syndrome were the most common reasons for discontinuation that accounted for 16.2% (35 patients) and 1.8% (4 patients) of cases, respectively, and occurred after a median of 17 months from the start of ibrutinib. Treatment discontinuations due to adverse events (AEs) were recorded in 25 patients (11.6%) after a median time of 6 months from the start of treatment and included infections/febrile events in 7 cases, bleeding events in 3 (intracranial hemorrhage 1), sudden death in 3, acute myocardial infarction in 1, ischemic stroke in 2, second malignancy in 3, diarrhea in 1. AF occurred during treatment in 14 (6.5%) patients and was the reason of ibrutinib discontinuation in 2. AEs leading to discontinuation was not specified in 3 cases. Other reasons for ibrutinib discontinuation in 6 (2.8%) patients were ASCT in 4, unplanned surgery in 1, unknown in 1. Survival probability at 12 months from treatment discontinuation due to AEs or DP/RS was 38.2 and 37.2 months respectively (p= 0.6). Conclusions. The results of this real-life study show that in unselected patients with R/R CLL the clinical activity of ibrutinib was comparable to that reported in CTs. However, a third of patients discontinued ibrutinib within 24 months from the start of treatment. An earlier introduction of ibrutinib in the treatment approach of R/R patients, a careful surveillance and management of toxicities will optimise the clinical benefits of ibrutinib in CLL patients treated in the clinical practice.

Abstract: INTRODUCTION. Kinase inhibitors and glycoengineered monoclonal antibody, such as obinutuzumab (G), have significantly changed the treatment landscape of chronic lymphocytic leukemia (CLL). Both like the BTK inhibitor ibrutinib (IB) and obinutuzumab plus chlorambucil (G-CHL) are approved as first line therapy in CLL patients unfit for a fludarabine-base treatment. While IB has proved to be superior to bendamustine-rituximab in a phase 3 trial and an ongoing retrospective ERIC study, no head-to-head comparison has been done for IB vs G-CHL in a real-world evidence study. The aim of this study was to compared the clinical efficacy of the fixed duration G-CHL treatment vs continuous treatment with IB. METHODS. The inclusion criteria for this observational study were patients with a diagnosis of CLL, requiring treatment according to the iwCLL guideline (Hallek M, Blood 2018) and considered unfit for fludarabine-base therapy by the treating physician belonging to the Italian CLL campus. Patients received ibrutinib 420mg daily until progression or unacceptable toxicity, while G was administrated at 100mg on day 1, 900mg on day 2 and 1000mg on days 8 and 15 of the 1st cycle, then at 1000mg from cycles 2-6. Chlorambucil was administrated according to the local policy. An IGHV gene sequence homology ³98% was considered as unmutated (U-IGHV), as opposed to mutated (M-IGHV). TP53 disruptions (TP53dis) included deletions and mutations. Progression-free survival (PFS), time-to-next treatment (TTNT) and overall survival (OS) were calculated according to the iwCLL 2018 guideline. Minimal residual disease (MRD), assessed by flow cytometry, was considered undetectable when & lt;10-4 (uMRD4). Survival curves were compared with the log-rank test and p & lt;0.05 was considered as significant. The study was approved by the ethic committee of Padua university hospital. RESULTS. We recruited 284 CLL patients from 16 hematologic centers, 104 were treated with G-CHL and 180 with IB as first-line treatment. Once TP53dis cases were excluded, 102 patients treated with G-CHL and 80 treated with IB were included for further analysis. Among patients managed with G-CHL the median age was 75 years and 20% were older than 80 years, 47% had a CIRS≥6 (range 2-18), 68% had a clearance creatinine & lt;70ml/min, 60% showed a Rai stage III-IV, 32% were U-IGHV and 11% harbored 11q deletion by FISH. Patients treated with IB displayed a better renal function (p=0.0011) and were enriched in U-IGHV cases (p=0.0001). After a median follow-up of 21 months, 23 patients relapsed (20 G-CHL, 3 IB), 16 required a subsequent treatment (14 G-CHL, 2 IB) and 17 died (10 G-CHL and 7 IB). Two patients in the IB arm developed Richter syndrome. After 8 months from the start of treatment, the overall response rates in the G-CHL and IB arms were 86% vs 77% (p=0.1480), including 25% vs 6% complete remissions (CR, p=0.0013) and 61% vs 71% partial responses (PR, p=0.6320). Remarkably, an uMRD4 by flow-cytometry was documented in 42% and 9% of G-CHL patients in the peripheral blood and bone marrow, respectively. The median PFS was 33 months for G-CHL arm, but not reached for IB patients. The 24months PFS, TTNT and OS was 67% vs 91% (p=0.0012), 83% vs 97% (p=0.0128) and 89% vs 95% (p=0.5314) for the G-CHL and IB arms, respectively. Interestingly, the depth of response influenced PFS only in the G-CHL arm both in terms of clinical response (the median PFS was 8, 29 and 38 months for no responding, PR and CR patients) and MRD status (the 24 months PFS was 82% vs 50% and 100% vs 58% for uMRD4 vs MRD+ evaluated on peripheral blood and bone marrow). While the PFS was significantly better with IB than with G-CHL in U-IGHV (p=0.007), it was superimposable for M-IGHV patients (p=0.1946). Dose reductions or discontinuations were recorded in 39% and 44% of patients in the G-CHL and IB arms. Atrial fibrillation and infections occurred in 2% and 6% (p=0.0442), and in 25% and 17% (p=0.1455) of patients in the G-CHL and IB arms, respectively. CONCLUSIONS. The Italian experience with G-CHL confirms the marked efficacy and safety of this combination, in particular for patients who reach a CR and/or an uMRD4. The continuous treatment with ibrutinib provides a better disease management in CLL patients unfit for fludarabine-base therapy, but some on them - particularly those with a M-IGHV status - can achieve a long-term disease control with a fixed duration obinutuzumab-based chemoimmunotherapy.

Abstract: Introduction. Elderly patients with chronic lymphocytic leukemia (CLL) and younger patients with comorbidities are often treated with chlorambucil (Chl), despite the relatively low response rates. The addition of anti-CD20 monoclonal antibodies to Chl substantially increases the response rates, without negatively affecting tolerability. Overall response rates (ORR) between 66% to 84% have been reported with these combinations, with complete responses (CR)ranging from 8% to 26%. Methods. We conducted a retrospective analysis on the use of the Chl-rituximab (R) combination as frontline treatment for elderly (≥65 years) and/or unfit (CIRS 〉 6) CLL patients treated at 15 different Italian hematologic centers. The main aim of the study was to further establish the safety and efficacy of the Chl-R protocol and investigate whether certain CLL patients for whom this protocol could be particularly effective could be identified. To this end, we performed a subgroup analysis stratifying patients according to FISH and IGHV results: high risk group (HR) included patients with 17p deletion, intermediate risk group (IR) patients with 11q deletion and/or unmutated IGHV, low risk group (LR) patients without 11q or 17p deletion and/or unmutated IGHV. Results. One hundred and two patients who underwent treatment between 2009 and 2011 were enrolled in the study. Patients' clinical and biologic characteristics are summarized in Table 1. Three patients discontinued treatment earlier than planned: 1 for an episode of autoimmune hemolytic anemia (AIHA) that developed after the 2nd cycle of Chl and before starting R treatment and 2 patients for disease progression after the 3rd and 5th cycle of Chl-R, respectively. The median number of Chl and R cycles administered in the 102 patients was 8 (range 2-12) and 6 (range 1-9), respectively. The planned treatment schedule was different among centers: the two main schedules used were Chl administered at 1 mg/kg for each cycle every 28 days, given at a fixed daily dose of 10 mg starting from day 1 and repeated for 8 cycles, and Chl administered at 8 mg/m2/day for seven days of each of eight 28-day-cycles. R was added to Chl from the 3rd cycle onwards and was administered on day 1 of each cycle at a dose of 375 mg/m2 during the first administration and 500 mg/m2 for the subsequent 5 cycles. On an intention to treat basis, the ORR was 87.1%. Thirty-two patients (31.7%) obtained a CR and 56 patients (55.4%) obtained a partial response (PR). Nostatistically significant differences were noted in terms of ORR for age above or below 70 years, fitness status, ECOG, bulky disease, cytogenetic risk abnormalities, IGHV mutational status, ZAP-70 or CD38 expression.Median progression-free survival (PFS) and time to retreatment (TTR) were reached at 43.7 and 72.3 months, respectively. Median overall survival (OS) was not reached; 86.1% and 81.2% of patients were alive at 48 and 60 months, respectively. The most frequent serious adverse event was grade 3-4 neutropenia, occurring in 13.7% of patients. Grade 3-4 extra-hematologic side effects were uncommon (9.8%). Subgroup analysis of the LR and IR patients (no HR patients were enrolled) showed that LR patients had a significantly better PFS than IR patients (65.8 months vs 35.2 months, p=0.001; Fig. 1),with 54.9% of patients remaining free from progression 60 months after treatment. Conclusions. Treatment of elderly and/or unfit CLL patients with the Chl-R regimen is associated with low toxicity, a high ORR and durable PFS. Particularly good results are achieved in CLL patients with a mutated IGHV profile and not carrying both 17p and 11q deletion, suggesting that in this low-risk subset of unfit patients Chl-R could represent the optimal therapeutic option, in consideration of safety, efficacy and costs.

Abstract: In a phase II trial, we evaluated chlorambucil and rituximab (CLB‐R) as first‐line induction treatment with or without R as maintenance for elderly chronic lymphocytic leukemia (CLL) patients. Treatment consisted of eight 28‐day cycles of CLB (8 mg/m 2 /day, days 1–7) and R (day 1 of cycle 3, 375 mg/m 2 ; cycles 4–8, 500 mg/m 2 ). Responders were randomized to 12 8‐week doses of R (375 mg/m 2 ) or observation. As per intention‐to‐treat analysis, 82.4% (95% CI, 74.25–90.46%) of 85 patients achieved an overall response (OR), 16.5% a complete response (CR), 2.4% a CR with incomplete bone marrow recovery. The OR was similar across Binet stages (A 86.4%, B 81.6%, and C 78.6%) and age categories (60–64 years, 92.3%; 65–69, 85.2%; 70–74, 75.0%; ≥75, 81.0%). CLB‐R was well tolerated. After a median follow‐up of 34.2 months, the median progression‐free survival (PFS) was 34.7 months (95% CI, 33.1–39.5). TP53 abnormalities, complex karyotype, and low CD20 gene expression predicted lack of response; SF3B1 mutation and BIRC3 disruption low CR rates. IGHV mutations significantly predicted PFS. R maintenance tended towards a better PFS than observation and was safe and most beneficial for patients in partial response and for unmutated IGHV cases. CLB‐R represents a promising option for elderly CLL patients. Am. J. Hematol. 89:480–486, 2014. © 2014 Wiley Periodicals, Inc.

Abstract: BACKGROUD. The B-cell receptor inhibitor ibrutinib has significantly improved treatment and overall management of chronic lymphocytic leukemia (CLL). Although several data derived from clinical trials suggest that ibrutinib increases the risk of atrial fibrillation (AF), the incidence of AF in a real-life cohort of CLL patients is unknown. Furthermore, it would be clinically relevant to identify patients at high risk of AF during ibrutinib. The aim of this study is to report the prevalence and risk factors of AF in ibrutinib-naive CLL, in order to define a predictive model for the development of AF and to test it in a cohort of subjects receiving ibrutinib. METHODS. We retrospectively analyzed data from 860 ibrutinib-naive CLL patients, referred to the Padua University hospital. Comorbidities, clinical and biological prognostic markers were analyzed using the Mann-Whiney, Fisher exact or Chi-square tests, when appropriated. Time to AF (TTAF) and overall survival (OS) were evaluated with Kaplan-Meier method. Univariate and multivariate Cox models were run to identify independent factors associated with AF. Then, risk values were obtained based on the hazard ratios. The score for AF was calculated as the sum of each risk values. Subsequently, the model was evaluated in a cohort of 354 ibrutinib-treated patients referred from 8 Italian hematological centers. RESULTS. Among the 860 patients from Padua hospital, 60% were male, 49% were older than 65 years, 73% were Binet A stage at diagnosis and 41% underwent at least one line of treatment. A prior history of AF was present in 21 patients (2.4%) at CLL diagnosis, while, among the remaining 839 patients without a previous history of AF, 47 (5.6%) developed it after a median follow-up of 9.4 years, resulting in an estimated incidence of almost 0.8% cases/year. Moreover, the median OS for patients with AF was significantly shorter than that patients without AF (12 vs 22 years, p 〈 0.0001). Based on univariate and multivariate analysis, variables associated with the risk of AF were: age 〉 65 years (p=0.001, 1 point), male gender (p=0.003, 1 point), valvular hearth diseases (p=0.001, 2 points), cardiopathy (p 〈 0.001, 3 points), hyperthyroidism (p=0.001, 1 point), chronic lung diseases (p=0.001, 1 point), diabetes mellitus (p=0.023, 1 point), severe infections (p=0.019, 1 point). As expected, no clinical and biological prognostic markers (i.e. Binet stage, IGHV mutation, TP53 abnormalities) for CLL were associated with an increased risk of AF. A predictive model was designed based on these factors and it stratified patients into 4 different groups. The estimated TTAF after 15 years of follow-up were 0%, 10%, 19% and 61% for patients with score 0, 1-2, 3-4, and ≥5 respectively (p 〈 0.001, Fig. 1A). Furthermore, it underwent internal validation using the bootstrap method. Subsequently, we applied our AF model to a cohort of 354 ibrutinib-treated patients, 64% were male, the median age was 69 years, 88 were treatment-naive, 70% U-IGHV and 39% harbored TP53 abnormalities. Forty-four subjects developed AF after a median observation of 25 months, with an estimated 2-year TTAF of 12%. Only 9 out of the 44 patients (20%) discontinued ibrutinib. Sixteen patients (4%) were classified as AF score 0, 218 (62%) score 1-2, 73 (21%) score 3-4 and 46 (13%) at least score 5. Our model was also able to identify patients at a higher risk AF during ibrutinib, in fact the 2-year risk of AF was 0%, 5%, 17% and 40% for patients with score 0, 1-2, 3-4, and ≥5 respectively (p 〈 0.001, Fig. 1B). Patients with a score of 5 or higher have a risk 20 times higher to developed AF than the other subjects (HR 19.6, 95% interval 7-52, p 〈 0.0001). So far, the OS of ibrutinib-treated patients with AF was not inferior to that of patients who did not developed AF (2-years OS 89% and 82%, respectively p=0.1252), but the median follow-up is only 2 years. CONCLUSIONS. In this study, variables associated with an increased risk of developing AF were identified and recapitulated into a scoring system. Our model proved to be a valid tool to identify patients at a higher risk of developing AF, including ibrutinib-treated patients. Taking these data into account, patients with a score ≥5 should be carefully monitored during ibrutinib treatment given the very high-risk of developing AF or should be considered for alternative therapies.
