Abstract Background Ponatinib, a third generation TKI, induces high rates of cytogenetic and molecular responses in heavily pre-treated CML patients (pts) resistant to ≥2 TKI and/or with a T315I mutation, especially in CP (J. Cortes at al., NEJM 2013). This agent induces diverse non-severe adverse events (AEs), a substantial proportion of pts experience severe arterial thrombotic events [(ATE) 17% by 3 years, J. Cortes et al., Haematologica 2015]. This agent is now licensed and it is mandatory to explore the rates of responses and ATE in the real-life setting. Aims We took the opportunity of the French ponatinib compassionate use program between May 2013 (end of PACE inclusions) and January 2014 (ponatinib license) to evaluate different outcomes in real-life conditions. Methods This is a multicenter observational retrospective study, designed to examine safety and efficacy of ponatinib in CML (any phase) resistant/intolerant to prior TKIs, in university and non-university hospitals, benefiting from the national ponatinib compassionate use program. Data were captured and validated following the rules and regulations of observational studies in France. Pts were analyzed in intention-to-treat, Molecular biology tests were performed according to ELN guidelines and BCR-ABL/ABL are expressed as % IS in all centers. Standard clinical [gender, age, weight, body mass index (BMI), cardiovascular risk factors (previous events, tobacco abuse, high blood pressure, diabetes)], onset of any CV events before and during ponatinib treatment) and metabolic biological parameters (cholesterol, triglycerides) were collected. Results Thirty-five observations were collected in CP, 4 in AP and 5 in BC. We focused our analysis on the 35 CP pts only. There were 16 (46%) males and 19 females, with a median age of 53 (18-76) years at CML diagnosis and 59 (20-82) years at ponatinib initiation. Sokal scores were high in 13 (37%), intermediate in 12 (34%), low in 4 (12%) and unknown in 6 (17%); Euro scores were high in 6 (17%), intermediate in 15 (43%), low in 3 (9%) and unknown in 11 (31%); Eutos scores were high in 7 (20%), low in 20 (57%) and unknown in 8 (23%) pts. All pts harbored "major" BCR-ABL transcripts except one (e19a2). Regarding cardiovascular risk factors (CVRF) prior to ponatinib, 12 pts (34%) were treated for hypertension, 1 was diabetic, 6 (17%) had dyslipidemia (all on statins). Tobacco abuse was present in 8 (23%) pts and 14 pts had some pre-existing CVRF in total. Median weight just prior ponatinib was 66 (48-107) kg, and BMI was 24.2 (17.85-33) kg/m2. Thirteen (37%) pts were on anti-aggregants or anti-coagulants (AAG/C) prior to ponatinib. All pts had received imatinib first-line for a median of 29.5 (4-123) months, 20 (57%) dasatinib and 14 (40)% nilotinib as second-line, one pt developed a T315I after imatinib only; 21 (60%) had received all 3 TKIs prior to ponatinib. At ponatinib initiation, 7 (20%) harboured a T315I mutation, 7 (20%) other mutation(s) 20 (57%) none. In one case mutation screen was not performed. The trigger for ponatinib was resistance (hematologic, cytogenetic or molecular progression) in 26 (74%) pts, intolerance in 7 (20%) pts and both in 2 (6%) pts. Pts were initiated at a median of 45 (30-45) mg daily after a median of 79.5 (12-217) months of disease duration. The median follow-up on ponatinib was 26 (2-37) months. The cumulative incidence of major molecular responses was 29% at 3, 42% at 6, 56% at 12 and 70% at 18 months. The overall survival is shown in figure 1. Four pts died, 3 of disease progression and 1 of myocardial infarction. Six (17%) pts had grade 3-4 hematologic AEs imposing transient ponatinib withhold, and 14 (40%) had diverse grade 1-2 non-hematologic, non-CV AEs (pancreatic, hepatic, skin toxicities, no grade 3-4). ATEs occurred in 19 (54%) pts after a median of 5.8 (0.7-21.7) months of ponatinib, without CVRF in 10 (53%) pts and without AAG/C in 13 (68%) pts. CVRF and AAG/C had no significant influence here on ATEs onset in univariate Cox model (p=0.76 and 0.37 respectively). Lipids and HbA1c were not modified on ponatinib. Overall 43% of pts stopped ponatinib for toxicity. Conclusion In the French compassionate use program in CP-CML patients resistant or intolerant to previous TKIs, ponatinib displayed strong efficacy, as previously described. In this unselected population of patients, ATEs were confirmed to represent the main tolerance concern in the real life setting.

Background The oral anti-apoptotic B-cell lymphoma 2 protein inhibitor venetoclax has shown strong activity in R/R AML in controlled clinical trials, and recently impressive results in treatment-naïve AML elderly patients with acute myeloid leukemia. However, limited data are available in the real-life setting. Methods This is a multi-center (n=4), retrospective study involving patients with treatment-naïve or Relapsed/Refractory (R/R) AML treated with Venetoclax in combination with HMAs. Data were collected after anonymous aggregation, in accordance with GCP and Helsinky declaration. Adverse events (AEs) were graded according CTCAE v4.03. Survival is estimated with Kaplan-Meyer method. Results Forty-four patients have been prescribed Venetoclax from March 2018 to June 2019 and completed at least 1 course of venetoclax (range 1-8, median 2, IQR 2.0 - 4.0), being evaluable in this analysis. Patients's characteristics are summarized in Table 1. Five/44 (11.4%) patients had a low risk AML, 21/44 (47.7%) had an intermediate risk AML and 14/44 (31.8%) patients had a high risk AML, according to ELN 2017 risk stratification (4 patients had no available ELN risk at baseline). Six out of 44 (13.6%) patients received Venetoclax in combination with HMAs as first line of therapy, whereas 14/44 (31%) as first line rescue for resistant AML, 15/44 (34.1%) at first relapse, 9/44 (20.5%) for second or further R/R AML. Among R/R patients who received Venetoclax, 17/38 (44.7%) and 21/38 (55.2 %) had received chemotherapy or HMAs as induction therapy, respectively. Overall, Venetoclax was combined with azacitidine in 19/44 patients (43.2%), with decitabine in 19/44 patients (43.2%), with Low-dose of Cytarabine in 5/44 (11.4%), and was performed in monotherapy in 1/44 (2.3%) patient. Three out of 44 patients (6.8%) received a maximum dosage of 100 mg daily, 2/44 (4.5%) received 200 mg, 37/44 (84.1%) received 400mg and 2/44 (4.5%) received 600 mg. Fifteen out of 44 (34.1%) patients reduced the dosage of venetoclax for concomitant Azole administration. The median follow-up is 75.5 (IQR 45.2 - 178.5) days for patients who received upfront venetoclax therapy, while 143 (IQR 49.2 - 235.7) days for R/R patients. In the first-line setting, no patients reduced venetoclax dosage for concomitant adverse events; two neutropenia grade IV and two thrombocytopenia grade III have been documented. In the R/R setting, 14/38 (36.6%) patients reduced venetoclax dosage for concomitant adverse events. Specifically, we reported 22 adverse events, of which 10 were grade III-IV (5 neutropenia grade IV, 2 pancytopenia grade IV, 1 neutropenia grade III and 2 febrile neutropenia grade III). The overall CR rate is 16.7 % in newly-onset AML patients and 28.9 % in R/R patients, respectively. Two out of 6 treatment-naive patients had an evaluable response at 2 months after the beginning of Venetoclax treatment, and 2/6 had an evaluable 4-months response: 1 stable disease (SD) and 1 disease progression (PD) at 2 months,1 SD e 1 complete remission (CR )at 4 months. Thirty-one out of 38 R/R patients had an evaluable response at 2 months and 21/38 had an evaluable 4-month response: 10 CR, 1 complete response with incomplete hematologic recovery (CRi), 14 SD and 6 PD at 2 months; 6 CR, 10 SD and 3 PD at 4 months have been documented. After a short follow-up period (75.5 days), no patients who received Venetoclax as upfront therapy underwent an allogeneic hematopoietic stem cell transplantation (HSCT). On the other hand, after a longer follow-up period (143 days), 5 out of 38 patients (13.2%) received a HSCT after Venetoclax therapy among R/R patients. Median Overall Survival was not reached in the newly-onset cohort. In R/R setting, median OS was 253 days (95% C.I. 157-349). Interpretation These data extend to the real-life setting some previous evidence obtained from trials. In particular, our data confirm that venetoclax plus HMAs or LDAC has an acceptable toxicity profile and is safe and manageable. However, especially in the R/R setting, hematological toxicity represents the most frequent adverse event, arising some concerns about the optimal drugs management. Although our data suggest a similar clinical activity of venetoclax combinations to that reported in clinical trials, further studies from the real-life setting are highly warranted to confirm venetoclax efficacy under normal clinical practice.

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

Abstract Abstract 644 Background: Omacetaxine is a first-in-class cetaxine with clinical activity against Ph+ CML and a mechanism of action independent of tyrosine kinase inhibition. Currently available tyrosine kinase inhibitors (TKIs) have not demonstrated activity in CML patients (Pts) who harbor the Bcr-Abl T315I mutation. Study Goals: To evaluate the safety and efficacy of subcutaneously (SC) administered omacetaxine in Pts with imatinib (IM)-resistant T315I+ Ph+ CML. Methods: Eligible Pts include adult CML Pts in chronic, accelerated, or blast disease phase (CP, AP, BP) with a confirmed Bcr-Abl T315I mutation and resistance to IM therapy. Induction schedule: 1.25 mg/m2 SC omacetaxine twice daily for 14 days every 28 days until hematologic response. Maintenance dosing: 1.25 mg/m2 SC omacetaxine twice daily for 7 days every 28 days. Study Results: To date, 90 Pts have been enrolled, with data available for analysis on 66 Pts (40 CP, 16 AP and 10 BP). The median age was 58 yrs (19-83) with 70% male Pts and a median disease duration of 54 mo (5-285). All Pts failed prior IM therapy, and 79% failed two or more prior TKIs. The presence of baseline T315I mutation was confirmed in all Pts. Baseline clonal evolution was evident in 10 (25%) CP, 6 (38%) AP, and 7 (70%) BP Pts. Eight CP Pts entered the study in CHR. The median follow-up for all Pts was 6.4 mo (0.2 to 29.6). Efficacy: In CP Pts, CHR was achieved in 26 Pts and maintained in 8 Pts for an overall CHR rate of 85%; the median duration of CHR was 7.7+ mo (1.7 to 23.6). Overall cytogenetic response was 27.5% with 6 (15%) Pts achieving a major cytogenetic response (MCyR, 4 complete, 2 partial). The median duration of MCyR was 6+ mo (0.8 to 16.1). Major molecular response was achieved in 15% of Pts and a reduction of baseline T315I mutated clone occurred in 56.7% of CP Pts. In AP Pts, overall hematologic response was achieved in 6 (37.5%) Pts with 5 CHR and 1 return to chronic phase (RCP). Median duration of response was 3.9+ mo (1.7 to 14.8). One AP Pt achieved a complete cytogenetic response; duration 1.9+ mo. In BP Pts, overall hematologic response was achieved in 3 (30%) Pts with 2 CHR and 1 RCP. The median overall survival for CP Pts has not been reached and 35 (88%) Pts were alive at the time of data cut- off. The median overall survival was 18.8 mo for AP and 1.8 mo for BP Pts. Median time to progression was 11.2, 3.1, and 1.2 mo for CP, AP, and BP Pts, respectively. Safety: Grade 3/4 related events occurred in 45 of 66 (68%) Pts. The most commonly reported events were thrombocytopenia (58%), anemia (36%) and neutropenia (33%). Non-hematologic toxicities were primarily grade 1/2 with the most frequently reported events of diarrhea (44%), fatigue (35%), pyrexia (32%), nausea (26%), and asthenia (21%). Grade 3/4 non-hematologic toxicities were uncommon with no events occurring in >5% of Pts and infection (3%) the most common event. Treatment delays occurred in approximately 50% of the Pts with median duration of approximately 12 days for all disease phases and cycles (CP=12, AP=10, and BP=12 days). The primary causes of delay were thrombocytopenia, neutropenia and pancytopenia. Sixteen deaths occurred during the study (5 CP, 4 AP, and 7 BP).Three deaths (1 CP, 1 AP, and 1 BP) were considered to have a possible relationship to omacetaxine: sepsis, pancytopenia, and sudden death with unknown cause, respectively. Conclusions: Omacetaxine administered by subcutaneous injection produces durable hematologic and cytogenetic responses with a safety profile consisting mainly of hematologic toxicities. Omacetaxine may provide a treatment option for this patient population who currently has no available approved drug therapies.

Abstract Abstract 109 Background: Despite progress in chronic myeloid leukemia (CML) therapy with tyrosine kinase inhibitors (TKIs), patients (pts) who fail dasatinib or nilotinib or pts with T315I mutation have no treatment options. Ponatinib is a potent, oral, pan-BCR-ABL inhibitor active against the native enzyme and all tested resistant mutants, including the uniformly resistant T315I mutation. Methods: The PACE trial (Ponatinib Ph+ALL and CML Evaluation) was initiated in September 2010. The objective of this international, single-arm, open-label, phase 2 trial is to establish the efficacy and safety of ponatinib. Pts with refractory CML in chronic, accelerated or blast phase (CP, AP or BP), or Ph+ acute lymphoblastic leukemia (ALL), resistant or intolerant (R/I) to dasatinib or nilotinib or with the resistant T315I mutation received 45 mg ponatinib orally once daily in one of 6 cohorts: CP R/I; CP T315I; AP R/I; AP T315I; BP/ALL R/I; BP/ALL T315I. The primary endpoints are major cytogenetic response (MCyR) for CP and major hematologic response (MaHR) for AP, BP or ALL. The trial is ongoing; projected enrollment is approximately 450. Data as of 18 July 2011 are reported. Results: At analysis, 403 pts were enrolled; 397 were treated and eligible. The median age was 59 (range, 18–94) years, 52% were male. Diagnoses were: CP R/I, n=188; CP T315I, 48; AP R/I, 52; AP T315I, 15; BP/ALL R/I, 51; BP/ALL T315I, 43. Median time from initial diagnosis to start of ponatinib was 6.2 years. Prior TKIs included imatinib (93%), dasatinib (85%), nilotinib (66%), and bosutinib (8%); 94% failed >2 prior TKIs, and 57% failed >3 prior TKIs. Overall, 88% had a history of resistance to dasatinib or nilotinib, and 12% were purely intolerant. Mutation status was determined centrally by MolecularMD. Overall, 106 pts had the T315I mutation. Of 291 R/I pts, 110 (38%) had non-T315I BCR-ABL mutations, most frequently F317L (10%), F359V (5%), E255K (4%), and G250E (4%). To date, 343 (85%) pts remain on therapy, 60 (15%) have discontinued (42 BP/ALL): 24 (6%) progressive disease (20 BP/ALL); 11 (3%) AE (3 pain, 3 thrombocytopenia, 1 each haemorrhage, loss of consciousness, enterocolitis, cytokine release syndrome, hepatotoxicity/pleuro-pericardial effusion after overdose); 8 (2%) died (3 related; 7 BP/ALL); 17 (4%) other. The most common drug-related AEs (≥10% any grade) were thrombocytopenia (19%; 15% grade 3/4), rash (18%), dry skin (13%), myalgia (12%), abdominal pain (11%; 3% grade 3/4), headache (11%), arthralgia (11%). Overall, 67 (17%) pts experienced at least 1 related SAE. The most common related SAEs (>5 cases) were pancreatitis 15 cases (3.7%), 5 cases each (1.2%) diarrhea, anemia, febrile neutropenia, and pyrexia. At the time of reporting, 159/397 eligible pts were evaluable for the primary endpoints. Median follow-up was 57 days. Of CP pts, 83 had an assessment at 3 months (10 at 6 months) or discontinued. In CP R/I, 25/60 (42%) attained MCyR (15 CCyR). In CP T315I, 13/23 (57%) had MCyR (11 CCyR). The overall CP MCyR rate was 38/83 (46%) (26 CCyR). Of AP, BP/ALL pts, 76 had an assessment at 1 month or later or discontinued. In AP, 17/23 (74%) R/I and 1/1 T315I pts achieved MaHR. In BP/ALL, 11/30 (37%) R/I and 6/22 (27%) T315I pts had MaHR. Conclusion: In this first analysis of the pivotal PACE trial, ponatinib has a favorable early safety profile, similar to that observed in phase 1, but with a lower incidence of pancreatitis. Initial response data after short follow-up indicate ponatinib has substantial anti-leukemic activity in this heavily pretreated population, and in pts with refractory T315I. These early efficacy signals replicate initial response results reported in the phase 1 setting. Updated data will be presented at the annual meeting.

Abstract Introduction: The outcome of patients with acute myeloid leukemia (AML) secondary to myelodisplastic syndrome (MDS) or therapy-related (t-AML) receiving conventional treatment and allogeneic stem cell transplantation consolidation (HSCT) is poor. CPX-351 is a new drug composed by liposomal encapsulated cytarabine and daunorubicin, at a fixed molecular ratio of 5:1. It showed superior results, compared to standard 3+7 induction, in a phase III trial (Lancet et al, JCO 2018) in patients affected by t-AML or AML with myelodisplasia-related changes and it is now commercially available for secondary AML (sAML). We recently published results from CPX-351 Italian Named (Compassionate) Use Program (CUP) which enrolled 73 elderly sAML patients (Guolo et al, Blood Cancer J. 2020) showing that CPX-351 is an effective induction regimen for high risk AML patients treated with a curative aim. With a limited follow up, our data suggested the good activity and tolerability of CPX-351. Good quality remissions with acceptable toxicity in the majority of patients was achieved and CPX-351 increased the feasibility of HSCT in a poor risk AML cohort. Scarce data are available on long term outcome of high risk patients receiving CPX-351 in the real life setting. Here we report the results from the extended follow up analysis of the Italian CUP. Results: Seventy three patients were enrolled between December 2018 and June 2019 in a compassionate use program (CUP) in 33 Italian Hematology Centers. Data collection began on July 2019 and included 71/73 patients (97.2%), enrolled in 31 Centers. As previously reported, median age was 65.5 years (52-79). Sixty-two (88%) patients had at least one relevant comorbidity upon enrollment. Six patients (9%) presented with ECOG 3-4 upon enrollment. With a median follow up of 22 months, median overall survival (OS) was 13 months (21.2 - 22.8 95% IC). Two-years OS was 28.6% in the whole cohort. In order to confirm the positive impact of HSCT in first complete remission (CR) and the correlation with the other variables, a landmark model was applied, including only patients alive and in CR at day 90. In landmark analysis, HSCT performed in first CR after CPX-351 was the only significant predictor of longer survival: median OS was not reached for patients transplanted in first CR Vs 12 months for patients who did not undergo HSCT, p < 0.05, Figure1). Two-year OS for patients who received HSCT was 57.6% vs 15.8% for patients who did not undergo HSCT. Conclusions: Results from the extended follow up of Italian CPX-351 CUP confirm the good activity CPX-351 in such a difficult cohort as sAML. Two-year OS for transplanted patients is high despite the high median age, the high frequency of severe comorbidities in this real life cohort of patients and the high frequency of high risk AML. On the contrary, non-transplanted patients show a poor outcome, thus confirming that CPX-351 induction as an optimal bridge to transplant induction therapy. Figure 1 Figure 1.

Abstract Background Long-term outcome of chronic lymphocytic leukemia (CLL) patients (pts) under ibrutinib therapy has been evaluated within clinical trials, and CLL progression seems to be strongly linked with the onset of BTK and PLCg2 mutations. These mutations have largely been studied in resistant pts. Limited data are available regarding the BTK and/or PLCγ2 mutations in pts on ibrutinib without evidence of disease progression. Ibrutinib was available in France during 2014 as an early access program (EAP) thus allowing the evaluation of prolonged use of Ibrutinib in a real-life setting. The objective of this study was to analyze the genetic profile of pts still on Ibrutinib after at least 3 years of treatment. We also explored minimal residual disease (MRD) and T-lymphocyte subsets. Results Data were collected from all pts who received ibrutinib via the EAP in 29 centers of the FILO group. Between February 2014 and April 2015, 204 pts began ibrutinib treatment. Only 63 (31%) remained on therapy 3 years later and blood samples were collected for 57 of them. For these 57 pts, median age at ibrutinib initiation was 67.7 years (46.9 to 84.1). Forty-five percent and 42.5% pts presented with 11q or 17p deletion respectively, and 17/18 pts tested harbored unmutated IGVH genes. Pts received a median number of 2 (0-5) previous therapies, consisting mainly of fludarabine-based regimens (73%), bendamustine + rituximab (48%), chlorambucil + anti-CD20 antibody (25%) or alemtuzumab (16%). The best response on ibrutinib therapy was clinical complete response, partial response and partial response with lymphocytosis in 31%, 56% and 13% of cases respectively. Median time between ibrutinib initiation and blood sample collection was 3.5 years (2.75 to 4.2). Median lymphocyte count was 2.62 G/L (0.37 to 121), and median CLL cell count was 0.52 G/L (0-117). No patient achieved MRD < 0.01% in the blood (by FCM). Thirty pts had CLL cell count higher than 0.5 G/L, allowing mutational analysis by next-generation sequencing. At least one BTK mutation was found in 17/30 (57%) pts, (C481S N=13, C481Y N=2, C481G N=1 and C481R N=2) (VAF 0.2-73%), and 4/30 (13%) pts harbored PLCγ2 mutations (L845G N=3, D993H N=1, R665W N=2 and C849R N=1) (VAF 1-11%). TP53 mutations were found in 14/30 (47%) cases, SF3B1 and NOTCH1 mutations in 6/30 (20%) cases, XPO1 and RPS15 mutations in 4/30 (13%) cases, ATM mutations in 3/30 (10%) cases, BIRC3 and POT1 mutations in 1/30 (3%) case. All pts with PLCγ2 mutations presented with both BTK and TP53 mutations. Neither the incidence of TP53 mutation nor the other CLL frequently mutated genes were different between BTK mutated and unmutated pts (p=NS). Moreover, the number of previous therapies (0-1 vs > 1) was not different between pts harboring BTK mutations or not (p=0.2). Study of T lymphocyte subsets showed a highly variable CD4/CD8 T- cell ratio (median=1, range 0.41-3.42), but, interestingly, the median number of CD4 T-cells was 584/mm3 (141-2481), with 92% of pts presenting with CD4 T-cells >250/mm3. This result suggests that ibrutinib treatment may not affect CD4 T-cell counts. With a median follow-up of 3.5 months from sample collection, 12/57 pts (21%) discontinued ibrutinib because of CLL progression (N=8), Richter syndrome (N=1), adverse event (N=1), septic shock (N=1) and unknown reason (N=1). Twelve pts progressed within 6 months after sample collection. Among them, BTK mutations were present in 11/12 cases and PLCγ2 in 2 cases. Only one patient experienced progression without BTK or PLCγ2 mutations. BTK mutations were found in 6 pts without evidence of progression at the time of last follow-up and longitudinal analysis is ongoing. Variant allele frequencies of BTK mutations were highly variable between pts (range 0.2%-73%) and were not different between progressing and non-progressing pts (p=0.2). Conclusion and perspectives In this real-life setting, only one third of pts remained on ibrutinib after 3 years. Even after such a long treatment exposure, ibrutinib as a monotherapy did not appear to induce complete immunophenotypic response. Fifty-seven percent of pts with CLL cell count > 0.5 G/L had BTK C481 mutations, and BTK mutations were found in all but one pt who progressed. This study also highlighted the onset of BTK and PLCγ2 mutations in long-term responders on therapy, before any evidence of disease progression.

T315i Mutation

Background Iclusig (ponatinib) is a third-generation tyrosine kinase inhibitor (TKI) indicated for adult patients with chronic, accelerated or blast phase CML resistant or intolerant to nilotinib or dasatinib or with Ph+ ALL resistant or intolerant to dasatinib or for patients with the T315I mutation. Long-term efficacy and safety of ponatinib have been demonstrated in clinical trials, but real-world data are still limited. Here, we report the data on ponatinib use in CML and Ph+ ALL patients in routine clinical practice collected over 3 years in Belgium. Methods This ongoing prospective registry (NCT03678454) is conducted in Belgium and includes patients ≥18 years of age eligible for ponatinib treatment per product label. Data on demographics, medical history, disease characteristics, treatment patterns, treatment outcomes and safety were collected for patients enrolled from 1 March 2016 (ponatinib reimbursement in Belgium) onwards. Median follow-up was 15 and 4.5 months for CML and Ph+ ALL patients, respectively. All analyses were descriptive. The study received Ethics Committee approval and patients' consents were collected as per Helsinki Declaration. Results In total, 50 patients (33 CML and 17 Ph+ ALL) were enrolled from 20 hospitals. The median age of CML and Ph+ ALL patients was 58 and 56 years, respectively. 91% of CML and 94% of Ph+ ALL patients had received ≥2, and 54% of CML and 29% of Ph+ ALL patients had received ≥ 3 prior TKIs. Potential risk factors for TKI cardiovascular toxicity were observed: hypertension (17 patients), history of cardiovascular disease (19), smoking (13), hypercholesterolemia (6), hyperlipidemia (5) and diabetes (8). The reasons for starting ponatinib were: intolerance to previous TKIs (20, 40%), refractoriness to previous TKIs (14, 28%), disease progression (8, 16%) or T315I mutation (8, 16%). At entry, 22 patients (44%; 11 CML and 11 Ph+ ALL) had a confirmed BCR-ABL mutation. Of these, 12 (55%; 6 CML and 6 Ph+ ALL) had the T315I mutation. Starting doses of ponatinib in CML patients were: 45 mg (70%), 30 mg (12%) and 15 mg (15%) once daily. One patient with CML started with 15 mg every 2 days. Starting doses in Ph+ ALL patients were: 45 mg (76%), 30 mg (12%) and 15 mg (12%). The median treatment duration was 380 days (range 15-2777) for CML patients and 123 days (range 13-2114) for Ph+ ALL patients, which included recently enrolled patients. Major molecular response (MMR) was achieved as best response in 19 (58%) CML patients and 7 (41%) Ph+ ALL patients; while 2 (6%) of CML and 3 (18%) of Ph+ ALL patients achieved complete cytogenetic response (CCyR) as best response. Of patients who started ponatinib due to intolerance to previous TKIs, 9 CML (64%) and 4 Ph+ ALL (67%) achieved MMR. There were 57 cases (38 in CML and 19 in Ph+ ALL) of dose reduction or interruption, due to AEs (74%), to prevent AEs (25%) and other reason (2%). There were 24 cases (19 in CML and 5 in Ph+ ALL) of dose increase: due to good tolerance of treatment (54%) and absent or low response (46%). At time of analysis, 29 patients (15 CML and 14 Ph+ ALL) had discontinued treatment, for the following reasons: AEs (34%), planned allogeneic transplantation (21%), disease progression (14%), intolerance (3%) and other reasons (28%). Treatment-related adverse events (AEs) were reported in 34 patients (68%); the most common were rash (26%) and dry skin (10%). Six (12%) patients reported ≥1 treatment-related serious AE (SAE): thrombocytopenia (2), palpitations (1), hypertension (1), pneumonia (1), coeliac artery stenosis (1), cholecystitis (1) and hyponatremia (1). One patient, with a history of congenital cardiomyopathy and aortic prosthesis, reported 3 serious cardiovascular events; these were considered as not related to ponatinib by the investigator. Conclusion Results from this real-world Belgian registry support the use of ponatinib in CML and Ph+ ALL patients who are resistant or intolerant to previous TKIs or have the T315I mutation. Most CML and a large proportion of Ph+ ALL patients obtained deep molecular responses. No new safety signals emerged with ponatinib treatment. The obtained results were in line with those of the PACE clinical trial, with the frequency of cardiovascular events apparently lower, possibly due to selection or improved monitoring of patients, or possible under-reporting vs clinical trial. Longer follow-up will be done to assess the long-term clinical efficiency in this real-life population.

Abstract Background. Pomalidomide in association with dexamethasone is approved for RRMM in 3rd line and beyond based on the MM-003 multicenter international phase 3 study that demonstrated greater efficacy for Pomalidomide plus dexamethasone over high dose dexamethasone. However, MM-003 mainly recruited advanced RRMM with a median of 5 prior lines. Few data is available regarding real life Pomalidomide-based treatment in 3rd and 4th line RRMM. The aim of this study was to study efficacy and safety of Pomalidomide-based treatment in 3rd and 4th line RRMM. Methods. We studied 108 consecutive RRMM treated with Pomalidomide-based treatment in 3rd and 4th line in a multicenter-based study. All assessment made according to IMWG. Results. The median age was 62.5 (range, 30-86), with 36% older than 65 years, sex ratio M/F 1.25 and ISS disease stage 2 or 3 in 58%. 100% were exposed to bortezomib and refractory to Lenalidomide. 52 patients (48%) had pomalidomide-based therapy as 3rd, and 56 (52%) as 4th line. 73% of patients received a double-based therapy (Pomalidomide plus Dexamethasone) and 27% received a triple based therapy (Pomalidomide, Cyclophosphamide and Dexamethasone). Overall ORR was 55%, with 20% ≥VGPR including 5% CR, and was not statistically different in 3rd versus 4th line, and with PCd versus Pd, although the former was always better. With a median f-up of 45 months, overall 77% and 49% had relapsed and died, respectively, with significantly less in benefit to combination and 3rd line compared to Pd and 4th line (p=0.020). The median PFS was 6 (CI95% 2.3;9.6) and 9 (5.5;12.5) months in 3rd and 4th line (p=0.04), and 6 (CI95% 2.8;9.2) and 12 (8.5;15.5) months in Pd and PCd (p=0.04), respectively. Interestingly, the estimated 3 years PFS for 3rd line and PCd was 34% and 32% respectively, greatly superior to 4th line and Pd, 13% and 18%, respectively. Similarly, the median OS from start of Pomalidomide was not reached in 3rd and in PCd lines versus 23months (5;49), (p=0.04), and 32 months (5;-) for 4th line and Pd use, respectively. Pomalidomide was never permanently discontinued for safety issues, but 30 (28% of patients had to reduced pomalidomide dose, 25% to N-1 that is 3mg/d and 3% at N-2 that is 2mg/d. Expectedly, more patients (increased by 10%) had to reduce pomalidomide dose in 4th line compared to 3rd line, although it was not statistically significant, but not with PCd versus Pd. Indeed Cyclophosphamide but not pomalidomide is reduced in modified in dose or scheme when facing safety issues. No patient died related to adverse events. AEs leading to pomalidomide-based modification in schema included hematological in 40% and non hematological AEs in 12% of patients. Overall, the most common adverse events grade 3 or 4 were neutropenia (22%), anemia (11%), thrombocytopenia (7%) and infectious disease (5%). Conclusion. Pomalidomide-based therapy demonstrates efficacy in the real life with a manageable safety profile. We demonstrate herein that early use and combination improves MM on pomalidomide in the real life. Further prospective studies are warranted to confirm this data on a larger MM population. Disclosures Hulin: Janssen: Honoraria, Research Funding; Celgene: Honoraria, Research Funding.

Abstract Introduction. Observational studies from patients treated outside controlled clinical trials offer real life information and are relevant to understand whether data derived from prospective trials are reproducible in the clinical practice. A retrospective observational study was carried out by the GIMEMA (Gruppo Italiano Malattie EMatologiche dell'Adulto) group in order to evaluate the clinical characteristics and outcome of patients with chronic lymphocytic leukemia (CLL) treated with ibrutinib in Italy within a Named Patient Program (NPP). The NPP was intended to offer free and early drug access to CLL patients until ibrutinib became available on the Italian market. Methods. Patients included in the NPP program had refractory or relapsed (R/R) disease with progression within 24 months after prior chemo-immunotherapy, and/or 17p deletion/TP53 mutations. Patients were also required to have an ECOG performance status ≤2; serum creatinine ≤2 times, liver enzymes ≤3 times and total bilirubin ≤1.5 times the upper limit of normal. Key exclusion criteria were: the need of a concomitant treatment with a strong CYP3A inhibitor or warfarin, an allogeneic stem cell transplantation within the past 6 months or an ongoing active infection. All patients included in the program received ibrutinib orally as a single agent at the standard dose of 420 mg daily. Clinical data of 110 patients included in the NPP program between January 2014 and November 2014 have so far been collected and analyzed using the Research Electronic Data Capture (REDCap) system. Patients were managed at 20 Italian centers and received at least one dose of ibrutinib. Clinical data were reported by the treating physicians. Results. The median age of patients was 69.9 years (range 49.8-83.3); 53% were in Rai stage III-IV, 32% in stage II and 15% in stage 0-I. Sixty-two percent of patients had relapsed disease, 38% were refractory to prior treatment. The presence of a 17p deletion and/or TP53 mutations was recorded in 51 R/R patients. Eighty-six percent of patients had an unmutated IGHV gene profile. The median number of prior treatments was 3 and included allogeneic stem cell transplantation in 4 cases. Two or more comorbidities were reported in 57 patients (52%) and included atrial fibrillation (AF) in 10 (9.1%) and hypertension in 40 (36.4%). After a median follow-up of 12.1 months (range, 1.6-24.6), 87 patients (79%) were still on ibrutinib. A response to ibrutinib was reported in 98/110 patients (89.1%). The best recorded response was a CR/CRi in 19 patients (17.3%), while a PR was reported in 79 patients (72%; PR-L 21.1%). Similar response rates were observed in patients with unmutated IGHV genes (91.9%) and in those with 17p deletion/TP53 mutations (90.3%). At 12 months, the progression-free survival (PFS) and overall survival (OS) were 92.9% (95%CI: 87.9-98.2) and 95.2% (95%CI: 91.1-99.4), respectively. PFS at 12 months of patients who achieved a response was 96.3%, 98.9% in unmutated IGHV patients, 90.7% in those with 17p deletion/TP53 mutations. Five patients (4.5%) died during the NPP program (1 patient each for sepsis, heart failure, ileus perforation, cancer, unknown cause). Adverse events (AE) were recorded in 75 patients (68.2%); in 47 (42.7%) they were grade ≥3. Any grade AEs recorded in ≥5% of patients were: infections (35%; grade ≥3, 22%), granulocytopenia (18.8%; grade ≥3, 17.2%), bleeding (15.5%; grade ≥3, 2.7%), fever of unknown origin or febrile neutropenia (12%; grade ≥3, 5.4%), AF (10.9%; grade ≥3, 4.5%), diarrhoea (8.3; grade ≥3, 2%), hypertension (7.2%; grade ≥3, 5.4%). A new event of AF occurred in 1/10 patients with a prior history of AF. Warfarin was required in 1 patient with AF and this was the reason for ibrutinib discontinuation. Conclusions. The results of the first interim analysis of this retrospective, real life study confirms that ibrutinib, as a single agent, is an effective treatment for patients with poor-prognosis CLL. Our data also suggest that ibrutinib given to unselected patients, in a compassionate-use program, shows a clinical activity and a safety profile comparable to those reported in prospective trials. Data collection is ongoing in order to complete the analysis of this large NPP cohort in Italy.

Background: To assess the efficacy and safety of treatment with abiraterone acetate (AA) in chemotherapy-naïve men with metastatic castration-resistant prostate cancer (mCRPC) in the ‘real-life’ setting. Methods: Data acquisition on the outcomes of the use of AA in chemotherapy-naive patients with mCRPC was performed by a MEDLINE comprehensive systematic literature search using combinations of the following key words: ‘prostate cancer’, ‘metastatic’, ‘castration resistant’, ‘abiraterone’, ‘real life’, and excluding controlled clinical trials (phase II and III studies). Identification and selection of the studies was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) criteria. Outcomes of interest were overall survival (OS), progression-free survival (PFS), 12-week 50% reduction in prostate-specific antigen (PSA), and grade 3 and higher adverse events. Data were narratively synthesized in light of methodological and clinical heterogeneity. Results: Within the eight identified studies that fulfilled the criteria, a total of 801 patients were included in the meta-analysis. Baseline PSA ranged between 9.5 and 212.0 ng/ml. Most of the patients had bone metastases. Duration of treatment with AA was longer in the studies with lower baseline PSA levels. The median OS ranged between 14 and 36.4 months. The PFS, assessed according to different definitions, ranged from 3.9 to 18.5 months. A 50% PSA reduction at 12 weeks was reached by a variable percentage of patients ranging from 36.0% to 62.1%. Finally, the rate of grade 3 and higher adverse events was reported in three studies and ranged from 4.4% to 15.5%. Conclusions: Despite the high grade of heterogeneity among studies, treatment with AA seems to ensure good survival outcomes in the ‘real-life’ setting. However, prospective studies based on patients’ characteristics being more similar to ‘real-life’ patients are necessary.
