Abstract: Undetectable measurable residual disease (uMRD) is achievable in patients with chronic lymphocytic leukemia (CLL) with the BCL2-inhibitor venetoclax alone or combined with the Bruton’s tyrosine kinase inhibitor ibrutinib. This phase 2, multicenter, MRD-driven study was designed to discontinue treatment upon reaching uMRD4 ( & lt;10−4) in patients with relapsed/refractory CLL receiving venetoclax monotherapy or after the addition of ibrutinib. Primary end point of the study was proportion of uMRD4 with venetoclax ± ibrutinib. Secondary end points were overall response rate, partial response, complete response, progression-free survival, duration of response, overall survival, and safety of venetoclax ± ibrutinib. Patients with uMRD4 at Cycle 12 Day 1 discontinued venetoclax. MRD+ patients added ibrutinib and continued both drugs up to Cycle 24 Day 28/uMRD4/progression/toxicity. After Cycle 24 Day 28, MRD+ patients continued ibrutinib. Thirty-eight patients (29% with TP53 aberrations; 79% with unmutated IGHV) started venetoclax. Overall response rate with venetoclax was 36 (95%) of 38 patients (20 complete; 16 partial response). Seventeen patients (45%) with uMRD4 at Cycle 12 Day 1 discontinued venetoclax. Nineteen (55%) MRD+ subjects added ibrutinib. After a median of 7 months (range, 3-10 months) of combined treatment, 16 (84%) of 19 achieved uMRD4, thus stopping both drugs. Two MRD+ patients at Cycle 24 Day 28 continued ibrutinib until progression/toxicity. After a median follow-up of 36.5 months, median progression-free survival was not reached; 10 patients progressed (4 restarted venetoclax, 3 without treatment need, 2 developed Richter transformation, and 1 dropped out). Seven (22%) of 32 patients remain uMRD4 after 3 years of follow-up. Neutropenia was the most frequent grade 3 to 4 adverse event; no grade 5 events occurred on study. This sequential MRD-guided approach led to uMRD4 in 33 (87%) of 38 patients, with venetoclax monotherapy or combined with ibrutinib, delivering treatment combination only in a fraction, and ultimately identifying the few patients benefiting from continuous therapy. This trial was registered at www.clinicaltrials.gov as # NCT04754035.

Abstract: Hairy cell leukemia (HCL) is a rare lymphoproliferative disease with an excellent prognosis after treatment with cladribine (2CDA), although relapse may occur during follow-up. The aim of the study is to review the efficacy, safety, long-term remission rate, and overall survival (OS) in those patients who received 2CDA as first-line treatment. We retrospectively reviewed data of HCL patients treated with 2CDA between March 1991 and May 2019 at 18 Italian Hematological centers: 513 patients were evaluable for study purpose. The median age was 54 years (range 24–88) and ECOG was 0 in 84.9% of cases. A total of 330 (64.3%) patients received 2CDA intravenously and 183 (35.7%) subcutaneously. ORR was 91.8%: CR was obtained in 335 patients (65.3%), PR in 96 (18.7%), and hematological response in 40 (7.8%) patients; in 42 (8.2%) no response was observed. Hemoglobin value ( p  = 0.044), frequency of circulating hairy cells ( p  = 0.039), recovery of absolute neutrophil count ( p  = 0.006), and normalization of spleen ( p  ≤ 0.001) were associated with CR compared to PR in univariable analysis. At a median follow-up of 6.83 years (range 0.04–28.52), the median time to relapse was 12.2 years. A significant difference in duration of response was identified between patients that obtained a CR and PR (19.4 years versus 4.8 years, p   〈  0.0001). Non-hematological grade 3 or higher early toxicity was reported in 103 (20.1%) patients. Median OS was not reached: 95.3%, 92.4%, and 81.8% of patients were estimated to be alive at 5, 10, and 15 years, respectively. Forty-nine patients died (9.5%), following an infection in 14 cases (2.7%), natural causes in 14 (2.7%), cardiovascular events in 13 (2.5%), a second neoplasm in 6 (1.2%), and progression of HCL in 2 cases (0.4%). Following treatment of HCL with 2CDA, 80% of patients are estimated to be alive 15 years after diagnosis.

Abstract: The GIMEMA phase II LLC1518 VERITAS trial investigated the efficacy and safety of front-line, fixed-duration venetoclax and rituximab (VenR) in combination in young (≤65 years), fit patients with chronic lymphocytic leukemia and unmutated IGHV and/or TP53 disruption. Treatment consisted of the venetoclax ramp-up, six monthly courses of the VenR combination, followed by six monthly courses of venetoclax as a single agent. A centralized assessment of minimal residual disease (MRD) was performed by allele-specific oligonucleotide polymerase chain reaction assay on the peripheral blood and bone marrow at the end of treatment (EOT) and during the follow-up. The primary endpoint was the complete remission rate at the EOT. Seventy-five patients were enrolled; the median age was 54 years (range, 38-65), 96% had unmutated IGHV, 12% had TP53 disruption, and 4% had mutated IGHV with TP53 disruption. The overall response rate at the EOT was 94.7%, with a complete remission rate of 76%. MRD was undetectable in the peripheral blood of 69.3% of patients and in the bone marrow of 58.7% of patients. The 12-month MRD-free survival in the 52 patients with undetectable MRD in the peripheral blood at the EOT was 73.1%. After a median follow-up of 20.8 months, no cases of disease progression were observed. Three patients had died, two due to COVID-19 and one due to tumor lysis syndrome. The first report of the VERITAS study shows that front-line VenR was associated with a high rate of complete remissions and durable response with undetectable MRD in young patients with chronic lymphocytic leukemia and unfavorable genetic characteristics. ClinicalTrials.gov identifier: NCT03455517.

Abstract: The treatment of chronic lymphocytic leukemia (CLL) has been radically changed in the last years thanks to the targeted therapies, including kinase (i.e. ibrutinib) and BCL2 (i.e. venetoclax) inhibitors. Venetoclax (VEN) in particular is able to obtain undetectable minimal residual disease (uMRD), though only in a proportion of patients (pts) when given as single agent, thus warranting the need of different strategies in those not achieving uMRD. We designed a phase 2 multicenter Italian study where ibrutinib (IBR) is added to VEN based on a MRD-driven strategy aiming at obtaining uMRD and discontinuing both treatments in pts who did not achieve uMRD with VEN mono. Study treatment started with VEN (ramp up to 400 mg/day as per current label) for 12 months. MRD status in peripheral blood (PB) and bone marrow (BM) was evaluated using the 6-color flow cytometry assay recommended by ERIC (CD5/CD81/CD79b/CD19/CD43/CD20). Pts with uMRD in both PB and BM at C12D1 discontinued VEN at C12D28 and entered the follow-up phase. Pts with detectable MRD in PB and/or BM added IBR 420 mg/day starting from C13D1 and continued both drugs up to maximum C24D28, uMRD, progression or unacceptable toxicity (whichever occurs first). After C24D28, pts with detectable MRD and still in response continued IBR alone. The primary endpoint was uMRD4 ( & lt;1 CLL cell in 104 leukocytes) in both PB and BM. We report here the results as of 15Jul2020 (data cutoff). Thirty-eight pts (recruited from Nov 2017 to Jul 2018) fulfilled eligibility and started VEN. Baseline characteristics included: median number of prior therapies 1 (range 1-4) (60.6% previously treated with FCR or FC); del(17p) in 8/33 (24%); TP53 mutations in 10/30 (33%), and unmutated IGHV in 24/30 (80%). At the data cut-off, 35/38 evaluable pts still in the study have reached C24D1, 1 pt discontinued treatment due to myelodisplasia (considered unrelated to study treatment) before C12D1 and 1 pt progressed on VEN monotherapy shortly before that timepoint, 1 evaluation is still missing due to COVID-19 restrictions. At C12D1, uMRD4 in PB was achieved in 19/38 (50%) pts (Figure 1), 17/19 (89.5%) had uMRD4 confirmed in BM. Overall response rate with VEN single-agent was 36/38 (94.7%), 9 CR and 27 PR. As per protocol, the 17 pts (45%) with uMRD4 in PB and BM at C12D1 discontinued VEN at C12D28. Nineteen responsive cases with detectable MRD at C12D1 added IBR to VEN starting from C13D1. The combination of IBR and VEN led to an improved reduction of the depth of MRD in all but 3 pts with 16/19 (84%) achieving uMRD4 in both PB and BM between C16D1 (first MRD assessment after starting IBR) and C24D1, thus stopping both therapies as per protocol. After a median follow-up of 25.4 months (range 6.1-33.5) from treatment initiation, no clinical progression was observed among those discontinuing treatment in uMRD, while MRD4 relapse occurred in 21/33. Median time to MRD4 relapse in those who achieved uMRD at any timepoint and discontinued treatment was 4 months (range 2-13). Twelve pts (6 treated with VEN only) remain uMRD after stopping treatment, with a median observation of 13 months (range 3+-18+) since confirmed uMRD4. Safety data were analyzed in the intention-to-treat cohort (39 pts). No cases of clinical tumor lysis syndrome (TLS) and/or biochemical TLS were reported in the 39 pts exposed to VEN. Adverse events (AEs) were mild, with no treatment discontinuations or dose reductions. Five Serious AEs (Table 1) and 130 AEs (Table 2) occurred in 28 patients, without any SUSARs. All 5 SAEs were deemed unrelated to study drug(s) and 4/5 have resolved without sequelae. In conclusion, we here present the updated results of our study including the combination phase of VEN with IBR. This sequential MRD-guided approach was feasible and led to deeper responses in about 85% of pts not achieving uMRD4 after VEN alone. With this tailored and time-limited strategy 33 out of 38 pts (87%) obtained uMRD4 in PB and BM either after VEN monotherapy or the IBR-VEN combination, indicating we may reach identical depth of response with a personalized intensification and avoid unnecessary drug exposure. Time to clinical progression and response to VEN retreatment in this cohort remain to be established as well as the biological characteristics of those pts with persistent MRD despite the combined treatment. Updated results with further sequential MRD and clinical monitoring after treatment discontinuation will be presented at the meeting.

Abstract: Background. Waldenström Macroglobulinemia (WM) is a rare indolent lymphoma typical of the elderly population, with a median age at diagnosis of 65-70 years and median overall survival of approximately 10 years. Age is the most important prognostic factor in WM, and unrelated mortality significantly impacts survival in elderly patients. The past two decades have witnessed important treatment advances in WM, with the introduction of anti-CD20 monoclonal antibodies in the early 2000s and of ibrutinib in more recent years. Less than 10% of WM patients are diagnosed at young age, and few studies have addressed their characteristics and outcome in the era of immunotherapy and targeted therapies. Here we report the presenting features, treatment and outcome of WM patients younger than 55 years diagnosed in 12 Hematologic Centers across Italy between 2000 and 2018. Patients and Methods. Diagnostic criteria were those established during the second International Workshop on WM (Owen et al, 2003) and were retrospectively applied to patients diagnosed before 2003. The overall survival (OS) observed in the study cohort was compared with the expected survival of the general Italian population matched by sex, age and calendar year. The expected survival estimates were derived from Italian life tables (Istituto Nazionale di Statistica, ISTAT). Results. The median age of patients included in the study was 50 years (interquartile range, IQR: 46-52). Their clinical characteristics at diagnosis are reported in Table 1. With a median follow-up of 5.6 years (IQR 3.1-9.1), 76 of 129 patients (59%) have been treated, at diagnosis (n=31, 41%) or after initial observation (n=45, 59%). The median treatment-free survival was 39 months. According to ISS-WM prognostic score, 58% were classified as low risk, 30% as intermediate risk and 12% as high risk. Frontline therapy included Rituximab in 71/76 patients (93%). Rituximab was associated with chemotherapy in 62 patients (82%), whereas 9 patients (12%) received a chemo-free induction. Five patients (7%) received chemotherapy only as first-line therapy (Table 2). The overall response rate (ORR) to induction therapy was 85%, including 39% CR+VGPR. Two patients received Rituximab maintenance for 2 years. The median progression-free survival (PFS) after first-line therapy was 76 months. Four of 76 patients (5%) received an autologous stem cell transplantation at relapse/progression. Overall, 14/76 patients (18%) received ibrutinib as first (n=2) or as subsequent line of therapy (n=12). During follow-up, 4/76 patients (5%) developed a solid cancer (bladder n=2, breast n=1, prostate n=1) and 2 a second hematologic cancer (chronic myelomonocytic leukemia n=1, secondary MDS n=1). Using a competing-risk model, accounting for death from any cause as the competing event, the cumulative incidence of second cancers was 2% at 5 years and 5.8% at 10 years. Three patients have died, 2 due to WM and 1 due to acute myeloid leukemia. The 5-and 10-year OS from diagnosis were 99% and 96% respectively. In a time-dependent survival analysis, considering therapy as a time-dependent covariate, the OS of treated and untreated WM patients was not significantly different (P = 0.162) (Figure 1). Among treated patients, the OS was significantly shorter in high-risk patients as compared with low- and intermediate-risk patients (5-year OS 85.7% versus 100%, P=0.018) (Figure 2). The OS of young WM patients was not significantly reduced as compared with age-, sex- and calendar year- matched general population (P & gt; 0.05) (Figure 3). Conclusions. The presenting features of young WM patients resemble those typically described in the elderly WM population. Among treated patients, more than half are low-risk according to ISS-WM, confirming age as the most important prognostic factor. More than 90% of patients received Rituximab as part of the upfront treatment, mainly in combination with chemotherapy. Ibrutinib seems to be preferred over autologous stem cell transplantation in the relapsed/refractory setting. The outcome of young WM patients treated in Italy in the contemporary era was excellent in terms of both PFS and OS, with a life expectancy not significantly reduced as compared with the general population.

Abstract: Marginal zone lymphomas (MZLs) are indolent nonfollicular B-cell lymphomas (INFLs) and have heterogeneous clinical behavior. Recently, time to progression of disease at 24 months (POD24) was identified to stratify overall survival (OS) in follicular non-Hodgkin lymphoma and in INFL. Here, we examined the ability of POD24 to predict subsequent OS in a large, international cohort of MZL as part of the NF10 prospective international registry headed by Fondazione Italiana Linfomi (FIL). POD24 was only calculated for MZL patients requiring immediate therapy and was defined as experiencing lymphoma progression within 24 months from diagnosis. Among the 1325 patients enrolled in the NF10 study, we identified 321 patients with MZL for whom immediate therapy was planned right after lymphoma diagnosis. Overall, POD24 was confirmed in 59 patients (18%). Three-year OS for patients with POD24 was 53% with a hazard ratio of 19.5 (95% confidence interval, 8.4-45) compared with patients without POD24 (3-year OS, 95%). Association of POD24 with OS was confirmed for the subgroup of splenic and extranodal MZLs. Assessment of POD24 stratifies subsequent outcome in MZL and identifies a high-risk population. This trial was registered at www.clinicaltrials.gov as #NCT02904577.
