Abstract Background: Autoimmune haemolytic anaemia (AIHA) is a relatively uncommon condition for acute fall in haemoglobin with grave consequences if not diagnosed and treated promptly. The literature on the clinical outcome, response to treatment, and occurrence of acute complications is relatively scarce from the real world. Aim: We retrospectively analysed 100 cases of autoimmune haemolytic anaemia (AIHA) for clinic-pathological features and response to therapy. Patients and methods: It is a single centre retrospective analysis of all cases of AIHA managed at our centre from Jan 2010- June 2016. Patients were analysed for the demographic features, presenting complaints, clinical/ pathological findings at diagnosis, types of therapy given and response to therapy. AIHA was diagnosed by features suggestive of haemolysis (anaemia with unconjugated hyperbilirubinemia, raised LDH and reticulocytosis) and/or positive DAT in the absence of any underlying secondary causes for anaemia according to the monospecific-DAT results and the thermal characteristics of the autoantibody, patients were classified as warm AIHA (DAT positive for IgG with or without C3D), cold agglutinin disease (DAT positive for C3D only with cold agglutinins), mixed (DAT positive for IgG and C3d with coexistence of warm autoantibodies and high titre cold agglutinins), or atypical AIHA (either DAT negative). Based on the severity of anaemia, patients were classified into very severe (Hb≤60gm/L), severe (Hb-61 to 80gm/L), moderate (Hb-81 to 100gm/L) and mild (Hb>100gm/L). Results: A total of 100 consecutive patients were included fulfilling the inclusion criteria. The median follow-up of the study population was 17.7months (mean - 28.2m, range-0.3-197m). The median age of the patients was 33y (mean 36.3y: range 13-80y). There was female predominance (n=64, 64%). Easy fatiguability (85%) followed by dyspnoea on exertion (75%) were commonest presenting complaints. The median duration of complaints was 3 months (mean 8.93: range 0.2- 96). Jaundice (58%) and cola coloured urine (11%) were other important manifestations. Preceding history suggestive of viral infections was present in 22% of the patients and only one patient had significant drug history temporally correlating with AIHA. Splenomegaly was present in 67% with a median palpability of 2cm (mean 2.71: range 0- 20) and hepatomegaly in 49% with a median palpability of 1cm (mean 1.402: range 0 - 8) below the coastal margin. Lymphadenopathy was present in 8% of the patients. On severity grading 67% had very severe anaemia, 21% had severe, 9% moderate anaemia and 1% had mild anaemia. 24% of the patients had simultaneous low platelet counts less than 1 lakh. 17% patients had atypical AIHA - DAT negative. 21% patients had secondary AIHA of which eight patients had simultaneous low platelets (suggestive of Evans). The commonest cause for the secondary AIHA was rheumatological disorders (SLE 15 patients, MCTD one patient) followed by lymphomatous disorders in rest. Most common therapeutic modality employed was corticosteroids (methyl prednisolone pulse therapy n-20, prednisolone n-67), followed by IvIg (n-4), chemotherapy (RCHOP-1, RCVP-1, CVP-1) and rituximab (100mg/wk - 1, 375mg/m2/wk - 2). 75% of the patients had some clinical response (CR 47%, PR 22%, SD 6%) to the first line therapy. The median time to response was 1.5 months. 52% of the patients required repeat therapy in the form either steroid-sparing agent, immunosuppressant or repeat course of steroids. Six patients required splenectomy. The response to second-line therapy was seen in 92% of patients (CR 31/52, PR 9/52, SD 8/52). More than two lines/ times of therapy for non-response/relapse was required in 10% of the patients, of whom, 50% of the individuals were steroid dependent. A total of two patients succumbed to the illness (first owing to tuberculosis possible exacerbated by immunosuppressive therapy, and second due to progressive disease). Limitations of the study: All limitations of a retrospective study are applicable to our study as well. The selection of patients with fairer prognosis can explain a lower mortality in our study. Conclusion: Primary AIHA is the commonest form of AIHA. Most secondary AIHA has rheumatological etiology. Response to steroids is good leading to considerable remission but which is not long lasting and majority requiring second line/ second time therapy with same or alternative agents.

Abstract Background In recent years, the introduction of the immunomodulatory drugs (IMiDs) thalidomide & lenalidomide & the proteasome inhibitor (PI) bortezomib has substantially improved the therapeutic options & prolonged survival of patients (pts) with multiple myeloma (MM). Current treatment strategies involve sequential exposure to these agents, though the most effective sequencing of exposure has yet to be determined. MM is still, for the majority of pts, a relapsing & incurable disease with poor survival outcomes & alternative treatment approaches in relapsing disease after exposure to currently available novel agents is an on-going unmet need. We report the results of extended follow-up in this patient cohort. Objectives We examined outcomes in pts with progressive disease following sequential exposure to thalidomide, bortezomib & then lenalidomide, to assess responses to these & subsequent therapies in a “real-life” single centre setting. Methods Pts were eligible for this retrospective study if they had received sequentially thalidomide-, bortezomib- then lenalidomide-based combination therapy (LenCom) for MM as per The National Institute for Health & Care Excellence (NICE) guidance. Case records were examined for diagnostic details, depth & duration of response to PI treatment & regimens employed. T0 was defined as the time point at which LenCom was discontinued, whether for progressive disease (PD) or intolerance (I). Response to therapy subsequent to T0& Progression Free Survival/Overall Survival (PFS/OS) were assessed & factors predicting outcome analysed (e.g. ISS stage at diagnosis, age, previous therapies received, previous depth & length of response to treatment). Results Between Jan’07-Sept’12, 55 pts (27 Male & 28 Female) were enrolled. Median age at diagnosis was 59 yrs (range 33-89);ISS scores were: 20% stage I, 28% stage II & 28% stage III (23% unclassified). The median number of lines of therapy prior to LenCom was 3 (range 2-6). First line therapy was thalidomide-based in 64%; 36% underwent ASCT & 4 pts underwent tandem ASCT/RIC AlloSCT. Second line therapy was bortezomib-based in 42% &  53% pts received lenalidomide as > 4th line. Median time from diagnosis to commencing LenCom was 52.5mns (range 4-146). 43 pts (77%) had reached T0 (PD n=29, I n=14). At a median of 66 mns follow up (range 12-162 mns), a median of 9 cycles (range 1-32) of LenCom were administered to all pts & 7 cycles (range 1 -32) to those who had discontinued LenCom. Dexamethasone was discontinued after median 12 cycles in pts reaching T0, being stopped in 28% (median 6 cycles before T0). Median PFS from commencement of LenCom was 16.2 mns. At 4 mns median follow-up post T0, a total of 26 pts have received therapy after T0, of whom 3 received lenalidomide-based treatment (11.5%) & 3 received bortezomib-based treatments (11.5%). Thalidomide based treatment was received by 13 pts (combined with Bendamustine in 3 & bortezomib in 2). Post-T0 pts also received clinical trial therapies (3 pts on SRT501 trial, 1 pt on pomalidamide companion study & 1 pt on KW2478 – a heat shock protein 90 inhibitor), thalidomide-based treatment (10 pts, 2 with bortezomib), & high dose dexamethasone. 13 pts (50%) demonstrated PD as maximum response to first post-T0 therapy. Duration of response was generally very limited (median 0 mns, range 0-6 mns). Second line post T0 treatments, including pomalidomide, were received by 12 pts with only 2 pts pts achieving a PR or better to Thalidomide & bortezomib based regimens. Third line post T0 treatments were given to 2 pts with 1 pt achieving a further brief PR to DT-PACE. With a median follow-up of 6.4mns (1-37), 31 pts have died (PD n=18, infection n=6, other n=7). Median OS from diagnosis & commencement of LenCom were 100 mns & 18.4 mns, respectively. Median OS from T0 was 3.9mns (range 0-33 mns), influenced by the b2-microglobulin at T0 (<vs.³ 3.0 mg/L: 9 vs. 4.8 mns, p=0.027). The depth of response to LenCom correlated with PFS (P<0.001) but not post-T0OS (p=0.68). Conclusion Pts with MM who have relapsed after sequential exposure to thalidomide, bortezomib & lenalidomide have very limited treatment options. At present, a wide range of treatments are used, including re-challenging with lenalidomide, bortezomib & trial based treatments. However, few pts achieve a meaningful response to therapy & survival is consequently extremely poor. Disclosures: No relevant conflicts of interest to declare.

Background: Depatuxizumab Mafodotin (Depatux-M; ABT-414) is an antibody-drug conjugate consisting of a specific antibody against activated EGFR and a cytotoxic agent with antimicrotubule activity. The INTELLANCE 2/EORTC 1410 phase 2 trial produced interesting results for the combination regimen of Depatux-M and temozolomide in EGFR-amplified glioblastoma patients at first recurrence. For the first time worldwide, our work investigated the clinical outcome and safety of this combination in a real-life population. Materials and Methods: Patients were enrolled from seven AINO (Italian Association of Neuro-Oncology) Institutions. The major inclusion criteria were: histologically confirmed diagnosis of glioblastoma, EGFR-amplified, one or more prior systemic therapies and ECOG PS ≤ 2. According to the original schedule, patients received Depatux-M 1.25 mg/kg every 2 weeks combined with temozolomide. The primary endpoints of the study were overall survival and safety. Results: A total of 36 patients were enrolled. The median age was 57 years, ECOG PS was 0–1 in 28 patients (88%), MGMT methylated status was found in 22 (64%), 15 patients (42%) received the combined treatment as second-line therapy. The median OS was 8.04 months (95% CI, 5.3–10.7), the 12 month-OS was 37%. On univariate and multivariate analyses, the MGMT methylation status was the only factor resulting significantly associated with survival. Grade 3 ocular toxicity occurred in 11% of patients; no grade 4 ocular toxicity was reported. No death was considered to be drug-related. Conclusions: The study reported the first “real world” experience of Depatux-M plus temozolomide in recurrent glioblastoma patients. Encouraging clinical benefits were demonstrated, even though most patients were treated beyond second-line therapy. Overall, the results are close to those reported in the previous phase 2 trial. Toxicity was moderate and manageable.

Abstract Autoimmune hemolytic anemia is a heterogeneous disease with respect to the type of the antibody involved and the absence or presence of an underlying condition. Treatment decisions should be based on careful diagnostic evaluation. Primary warm antibody autoimmune hemolytic anemias respond well to steroids, but most patients remain steroid-dependent, and many require second-line treatment. Currently, splenectomy can be regarded as the most effective and best-evaluated second-line therapy, but there are still only limited data on long-term efficacy and adverse effects. The monoclonal anti-CD20 antibody rituximab is another second-line therapy with documented short-term efficacy, but there is limited information on long-term efficacy and side effects. The efficacy of immunosuppressants is poorly evaluated. Primary cold antibody autoimmune hemolytic anemias respond well to rituximab but are resistant to steroids and splenectomy. The most common causes of secondary autoimmune hemolytic anemias are malignancies, immune diseases, or drugs. They may be treated in a way similar to primary autoimmune hemolytic anemias, by immunosuppressants or by treatment of the underlying disease.

Abstract Abstract 2294 Background. The TKIs Nilotinib and Dasatinib offer additional therapeutic options for patients with CML who are resistant or intolerant to Imatinib. These agents, active against the majority of Imatinib resistant BCR-ABL mutated clones, have a different pattern of kinase target selectivity, pharmacokinetics parameters, cell uptake, efflux properties and adverse events profiles. Preliminary results suggest that some patients may respond to a second TKI used as third line therapy, but little is known about the long term benefit of such an approach.Aim of this collaborative Italian study was to verify the response (rate and duration) and the clinical outcome in patients with CML treated with a third TKI after sequential failure of the previous ones. Methods. We evaluated 66 patients with CML, resistant/intolerant to Imatinib and treated with Dasatinib or Nilotinib, then switched to a third- line TKI after treatment failure. Of these, 29 patients were treated with dasatinib after imatinib/nilotinib failure and 37 with nilotinib after imatinib/dasatinib failure. Patients were monitored with complete blood counts, cytogenetic analysis, bone marrow aspiration RT-PCR and mutational analysis. Results. A total of 66 patients (median age 63 years, range, 33–85 years) were treated with sequential TKIs; 40 (61%) patients had received interferon-a before starting Imatinib; 26 (39%) patients received imatinib as first line therapy. The median time on imatinib therapy was 47.5 months (range 4–101 months). At the start of nilotinib as second line, 27/29 (93%) patients were in CP, 1 (3.5%) in AP, and 1 (3.5%) in BP. 9 patients (31%) had developed mutations before starting treatment. The median time on second line TKI was 8 months (range 2–36 months). In the resistant patients 4 new mutations were identified (F359V in two patients, T315I, Y253H+F359V). At the start of dasatinib as second line, 33/37 (89.2%) patients were in CP, 4 (10.8%) in AP. 7 patients (18.9%) had developed mutations before starting treatment. The median time on second line TKI was 14 months (range 4–59 months).In the resistant patients 5 new mutations were identified (F137L in three pts, M318T, M244V+F317L). At the start of the third TKI, 60/66 (90.9%) patients were in CP, 5 (7.6%) in AP, and 1 (1.5%) in BP. Of these, 7 patients (18.9%) on dasatinib and 7 (24.1%) on nilotinib had mutations before starting treatment. The best response to the third line treatment with TKI was 10 (15.2%) MMR, 10 (15.2%) CCyR, 8 PcyR (12.1%), 5 (7.5%) mCyR, 24 (36.4%) CHR and 9 (13.6%) No Response (NR). In the dasatinib group, 9 (31%) patients discontinued treatment because of toxicity versus 17 (45.9%) patients in the nilotinib group.Two new mutations (F317L, E255V) emerged with dasatinib as third line therapy.After a median follow up of 13 months (range 2–37 months) 50 patients (48 CP, 2 AP) are continuing therapy (33 on nilotinib, 17 on dasatinib).Since the start of the third TKI, 61 patients (92.4%) are still alive for a median overall survival of 110 months (range 15–300) (52 CP, 7 AP, 2 NA); the 5 deaths (7.6%) were caused by disease progression and spread of the gene mutation T315I. Discussion. In our study, about one third of patients derived benefit from the use of three sequential TKIs; patients with better, longer response (28.7%) to third TKI were the same patients with a better response to the Imatinib and 2TKIs therapy. All these patients had taken interferon therapy before the Imatinib. In this subset of patients (good responders: CCyR and MMR) 5 patients developed mutations that were sensitive to the sequential treatment.The lack of a durable cytogenetic remission could be explained by the emergence of new kinase domain mutations as patients are exposed to sequential TKI; a change of therapy resulted in an adequate response. In our series, patients with poor prognosis showed mutations not sensitive to the TKIs treatment. Conclusions. Although allogeneic SCT is the treatment of choice in all patients failing 2 TKIs who are suitable candidates for this approach, alternative strategies are required for ineligible patients. The use of a third TKI after failure of two previous TKIs induces response in some patients. Longer follow up of a larger series of patients is needed to determine the long term impact of the response. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 4736 Background: Tyrosine Kinase Inhibitors (TKI) are the first line therapies for patients with chronic myelogenous leukemia (CML). The value of survival gains to patients associated with TKI treatment—in aggregate or relative to the cost of treatment—is unknown. Methods: Multivariate Cox proportional hazard models are used to construct real-world, community-based estimates of survival improvements in CML associated with the introduction of first-line TKI therapy, controlling for characteristics of patients which may independently affect survival. We then employ an economic framework following Becker, Philipson and Soares (2005) to calculate social value of infra-marginal improvements in survival gains due to treatment with TKIs. Finally, the value of community-based improvements in CML survival from treatment by newer TKIs used in second line is estimated by combining community-based survival data for first-line TKIs, along with clinical data on health improvements for CML patients receiving a TKI in second line. Results: Introduction of first-line TKIs in 2001 is associated with a real-world decrease in the all-cause mortality hazard rate of 0.183 (p < 0.01) for CML patients. A decrease of this magnitude is associated with an increase in life expectancy from 60 to 110 months for treated CML patients with median survival length in 2001. We estimate that patients place an annual value of $110,000 on first-line treatment with TKIs. This implies that for all patients in present and future CML cohorts, the present social value of first-line TKI therapy is $88bn. The present value of costs is estimated to be $8bn, suggesting that more than 90% of social value of TKIs in first line therapy is retained by patients. In second-line CML therapy, use of newer TKI agents is estimated to have created $47bn in social value, of which roughly 88% is retained by patients. This estimated value of the newer TKIs does not incorporate possible benefits in first-line therapy. Conclusions: In total, the TKI class in first and second-line theray has created over $135bn in social value. Approximately 90% of this value is retained by patients; approximately 10% is recouped by manufacturers. These estimates suggest that at current price levels, the vast majority of value created by new therapies in CML is appropriated by patients. In addition, since our estimates of survival community-based improvements are somewhat smaller than those contained in clinical trial estimates, this suggests the potential value of addressing real-world obstacles to efficacy, such as poor adherence.

Abstract Introduction Splenic marginal zone lymphoma (SMZL) is an indolent B-cell lymphoma characterized by splenomegaly, frequent moderate lymphocytosis with or without villous morphology and possible involvement of various organs, especially the bone marrow (BM). Diagnosis is classically based on the spleen histology, but it can be made on the BM biopsy, based on the typical intrasinusoidal cell infiltration pattern and immunohistochemistry. Different therapeutic options are available, but to date there are no conclusive comparative data. Patients and methods We retrospectively analyzed 83 consecutive patients with a diagnosis of SMZL observed at our Institution between 1999 and 2013. The diagnosis was based on the BM biopsy in 79 patients; the BM was negative in 4 patients. Diagnosis was histologically confirmed on the spleen in 27 patients who underwent splenectomy. Patients presented a median age of 72.5 years (range 38-84); 43 were males. The median spleen size at diagnosis was 145 mm, ranging from 100 to 300 mm. The majority of patients were stage IV at diagnosis for BM infiltration (95%); B symptoms were present in 4 of them (4.8%). Forty-two patients (50.6%) had a lymphocytosis at diagnosis and 13 (15.6%) presented an IPI score higher than 3. Thirty-five of them (42%) had a MZL BM infiltration superior to 30% of the total bone cellularity. Forty-two patients (50.6%) underwent a watch and wait policy (WW), while 41 (49.4%) were treated within 6 months from diagnosis, mainly because of symptomatic splenomegaly; in these patients, treatment consisted of splenectomy, chemotherapy or chemotherapy plus immunotherapy with Rituximab. The features of patients submitted to WW with respect to patients treated at diagnosis were comparable for the various parameters mentioned above, except for spleen size (higher in patients treated at presentation) and lymphocyte count (higher in patients who were observed). After a median follow-up of 64 months, the overall median survival was 96%. Among the 42 WW patients, 18 (42.8%) are still untreated after a median follow-up of 57.5 months, while 24 (57.2%) have required therapy; the median treatment-free interval in these patients was 25.5 months. Concerning the 41 patients who underwent treatment at diagnosis, after a median follow-up of 50 months, 13 (31.7%) have required a subsequent second-line treatment. The interval between first-line approach and re-treatment in patients treated at diagnosis was 30 months. Overall, 27 patients were treated with splenectomy only (either at diagnosis or after a WW period): only 6 of them (22%) had a subsequent progression after a median latency of 42 months; 26 were treated with chemotherapy alone (alkylating agents in the majority of them, combination therapy in a minority): 15 of them (60%) had a subsequent relapse or progression after a median of 9 months; 12 patients received a Rituximab-containing regimen: of these, only 2 (16%) have so far required a second-line therapy after 10 and 26 months respectively. Conclusions The WW policy is a valid option for asymptomatic patients: in these patients, after 4.5 years from diagnosis more than 40% is still untreated. In patients requiring treatment, splenectomy alone is followed in the majority of patients by a long period of good disease control: only 22% required a second-line therapy after 3.5 years. The addiction of Rituximab to chemotherapy seems to reduce the probability of relapse and to prolong the response duration. However, these preliminary data need to be confirmed by larger studies.

Abstract Introduction: Ruxolitinib (Rux) has been recently approved as second-line therapy in patients (pts) with Polycythemia Vera (PV) resistant/intolerant to hydroxyurea (HU). Median age of PV pts enrolled in the pivotal Response trials was around 60 yrs; at present, no data is reported on the use of Rux in elderly pts. Aims: In a real-world cohort of PV pts treated with Rux, we investigated whether the efficacy and safety of Rux were comparable in pts who initiated therapy when aged ≥75 years compared with younger pts. Methods: After IRB approval, clinical/laboratory data of 934 WHO2016-defined PV pts followed in 29 Hematology Centers were retrospectively collected. Of them, 168 (17.9%) were considered resistant/intolerant to HU at any time during follow-up by responsible physician and shifted to Rux as second-line therapy. Results: Among the 168 pts treated with Rux, 42 (25%, median age 78.2 years) were aged ≥75 yrs at Rux start, 74 (44%, median age 67.7) were aged 60-74 and 52 (31%, median age 53) were &lt;60 at Rux start. No significant differences were observed between the 3 groups, apart from a lower need for phlebotomies in pts aged ≥75 yrs and lower presence of palpable spleen in older pts (age ≥60), that more frequently switched to Rux due to HU intolerance (Table 1). Median duration of HU treatment was 41.0 months (IQR 14.6 - 85.8), with a trend for a longer median treatment duration in pts aged ≥75 [61.0 months (IQR 21.5 - 89.6) vs 35.9 months (IQR 13.4 - 79.6), p=0.04]. Rux starting dose was similar across age groups; however, more elderly pts underwent Rux dose reductions during follow-up (45.2% in pts aged ≥75 vs 28.6% in younger pts, p=0.04). Responses during Rux therapy are reported in Table 2, with no significant differences between the 3 groups at any time. In the overall cohort, response on PV-related symptoms at 6 and 12 months was significantly higher in pts who switched to Rux because of HU intolerance; however, this difference was not observed in pts aged ≥75 yrs. As to the most common hematologic Rux-related toxicities, grade 3-4 anemia and thrombocytopenia were observed in only 2 (1.2%) and 5 (3%) pts, with no difference across age groups (p=0.45 and p=0.18). However, any grade anemia and thrombocytopenia during Rux were more frequently observed in pts aged ≥75 (68.3% vs 51.7% of anemia, p=0.06 and 12.2% vs 3.5% of thrombocytopenia in younger pts, p=0.04). Nineteen and 4 pts experienced infectious and thrombotic complications during Rux with incidence rates of 0.59 and 0.12 per 100 patient-months, respectively, comparably in younger and older (≥75) pts (p=0.75 and p=0.29, respectively). Notably, 6 infections were herpes simplex/zoster virus, comparably distributed between the 3 groups (p=0.60). Permanent Rux discontinuation was needed in 14 pts (8.3%) after a median Rux exposure of 7.8 months (IQR 4.6 - 17.6) (incidence: 0.41 per 100 pts/months). Discontinuation was comparable between age groups, with Rux stop in 4 pts aged ≥75 yrs and 10 younger pts (2.4% vs 5.2% at 8 months, log-rank p=0.75). At last follow-up, 2 pts had died (1 from 2 nd neoplasia after 19.1 months from Rux start and 1 from acute leukemia after 3.3 years), both pts aged 60-74 yrs. Conclusions. In this real-world analysis, use of Rux in HU resistant/intolerant elderly PV pts was effective and safe despite the more frequent need for dose reductions. Older age should not discourage Rux therapy, but stricter hematological monitoring may be suggested. Figure 1 Figure 1.
