Abstract Objective: To evaluate response of homoharringtonine in patients with high risk AML or as a second-line therapy in patients with AML refractory to anthracycline based chemotherapy. Patients and methods: From Jan 1998-Jan 2006, there were 66 patients enrolled in this regimen. Male:female=40:26. Median age was 47 (17–69). There were 48 newly diagnosed AML, 5 relapsed AML and 13 secondary AML (secondary to MDS) in this group. Among these patients, there were 40 patients untreated previously — 20 patients had unfavourable chromasomal abmormalities, 10 patients had pgp positive, 10 patients had normal chromasome but high CD34 expression on leukemic cells. The remaining 26 patients were previously treated with daunorubincin or mitoxantrane combined with cytarabine at least two cycles and failed to achieve response. Homoharringtonine was given at dose of 4mg/m2/d(2.5mg/m2/d for age≥60 years) intraveniously for 7 days. Cytarabine was given at dose of 100mg/m2/d at same time. The therapy was repeated every 21 days.Post remission therapy was divided into two cohot —same regimen maintainance in 20 cases and cytarabine 1g/m2/d q12h for 4 days at least 4 cycles in 20 cases. Results: 40/66 patients achieved complete remission. 3/66 achieved partial remission. In patients refactory to anthracycline based regimen, the CR rate was 57.7%(15/26). In previously untreated high risk AML patients,the CR rate was 62.5%(25/40). Median disease free survival were 4.25 months (2–30) in cohot 1 and 18 months (12–47) in cohot 2 (P<0.05). CD95(APO-1/Fas) was tested by flow cytometry during treatment. APO-1/Fas (CD95) increased from (9.56±5.58)% to (25.64±0.70)% after induction chemotherapy. Main toxicities were marrow suppression and infection. There were 7 early deaths, 5 patients died of cerebral hemorrage and 2 cardiovascular events. Conclusions: Homoharringtonine is effective in patients with high risk AML. It is also a choice of second line therapy in patients refractory to anthracycline based chemotherapy. Intensive post remission therapy is superior to conventional dose maintainance therapy in high risk AML. One of the ways for homoharringtonine to induce leukemic cell apoptosis is probably through Fas pathway.

Abstract Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is no longer the first treatment option for patients with chronic myelogenous leukemia (CML) but there is a considerable debate about its use as a second line therapy. When used in this indication the second-generation tyrosine kinase inhibitors (2G-TKI) induce complete cytogenetic responses (CCyR) in 40–50% of patients in chronic phase but those without CCyR are unlikely to benefit in long term. It is therefore important to identify groups of patients with a good outcome after transplantation so that this may be offered as second line therapy where appropriate. The outcome of allo-SCT has improved over time so we restricted our analysis to the most recent 8 years to coincide with the introduction of imatinib into clinical practice. 131 patients received myeloablative transplants from January 2000 till December 2007. 67 patients were transplanted in chronic phase (14 in second and 2 in third chronic phase), 46 in accelerated phase and 2 in blastic phase. Forty-nine patients received imatinib at some point prior to transplantation and 30 of these experienced failure of imatinib therapy (as defined by European LeukemiaNet criteria). Conditioning consisted of cyclophosphamide and total body irradiation for 51 recipients of sibling stem cells. In addition in vivo T cell depletion with anti CD52 antibody (Campath 1H) was used for 80 unrelated donor transplants. The median age of the patients was 33.4 (15 to 56) years and the median disease duration at transplant was 13 (2 to 105) months. The probability of overall survival (OS) at 3 and 5 years was 64.8% and 62.6% respectively. We confirmed the prognostic value of the EBMT risk assessment score (Gratwohl) and pretransplant level of the C-reactive protein (CRP) and developed a combined additive pretransplant scoring system based on these predictive factors (EBMT risk assessment score plus 0 for CRP <2 mg/L, 1 for CRP from 2 to 10 mg/L, and 2 for CRP >10 mg/L). This identified 5 prognostic groups (Figure 1) with 3yr probabilities of survival of 92.6% (N= 27, score 0–1), 86.2% (N=29, score 2), 58.2% (N=29, score 3), 47.5% (N=20, score 4) and 30.8% (N=26, score 5 or more). The patients who failed imatinib (N=30) had significantly higher prognostic scores on the above described pre-transplant scoring system compared to the rest of patients transplanted (p=0.001). However, in a multivariate analysis adjusted for prognostic scores, their OS was significantly better (p=0.032). The OS in the best prognostic group is comparable with that of unselected patients treated with imatinib and it is possible that their long-term survival might be better. Allogeneic transplantation is unlikely to be preferred as the first line therapy even in selected patients due to its higher early mortality but our data support its use as second line therapy in patients in chronic phase who failed imatinib and have poor pre-2G-TKI predictive factors for CCyR as determined previously at our institution (namely Sokal risk score at diagnosis, the best cytogenetic response obtained on imatinib, G-CSF requirement during imatinib therapy and time from detection of imatinib failure to onset of 2G-TKI therapy) but achieved good score on the pre-transplant scoring system. It should also be used for those whose disease is more advanced where the 2G-TKI do not offer durable remissions. Figure 1 Figure 1.

Abstract Abstract 1796 Introduction: FCR chemoimmunotherapy is recommended as first line therapy for fit cll patients. Since the 2007 EBMT guidelines based on the previously published trials using FCR, the definition of high risk CLL has evolved, to include biologic parameters (TP53 disruption by deletion/mutation, high b2-microglobulin level, IgVH unmutated, complex karyotype), refractoriness (progression during fluda-based regimen or within 6mo of completion), and also remission duration (high risk if PFS after FCR <24mo, ultra-high risk if TTNT <24–36mo with TP53 del/mut). However, few data are available regarding the characteristiscs, response rate and outcome of CLL patients treated in second line after FCR first line. Patients and methods: In this multicentric retrospective study, we collected data from 117 patients who relapsed after FCR first line therapy and received second-line therapy (according to NCI2008 guidelines). Results: At the time of initial FCR therapy: patients characteristics were as follows: Binet B/C 87.2%, unmutated IgVH 52.2%, del11q 25.6% (n=30/81 with FISH available), del17p 6.8% (n=8/87 with FISH available), bulk>5cm 22%, complex karyotype 21% (n=12/57 with karyotype available). FCR yielded 93% ORR, with 66% clinical CR, 27% PR, and 7% failed to respond. Median PFS and TTNT were 27mo and 32.5mo, respectively. At the time of relapse: patients characteristics were as follows: del11q 16.4% (n=19/65 with FISH available), del17p 19% (n=22/77), bulk>5cm 26%, complex karyotype 44% (n=24/54 with karyotype available). According to FCR remission duration, 11.1% of patients were considered as truly FCR-refractory, 47% had PFS<24mo, 34.2% had TTNT<24mo. TTNT<24mo after FCR was correlated to age>65y, del17p (20% vs 0%) and complex karyotype (38% vs11%), but not with gender, IgVH status, del11q, or bulk>5cm. Based on FCR-refractoriness, or TTNT<24mo and/or del17p, 53 patients were considered as ultra-high risk (45.3%). Various regimen were used for second-line treatment after FCR: R-bendamustine (n=47, 40.2%), alemtuzumab-based therapy (single agent or with chemo/dexa, n=22, 18.8%), R-CHOP (n=15, 12.8%), FCR (n=14, 12%), and other miscellaneous regimens (as follows: R-alkylator (n=6, 5.1%), R-DHAP (n=4, 3.4%), R-methylprednisolone (n=3, 2.6%), or investigational drugs (n=6, 5.1%)). Thus, 74.3% of patients received a second course including rituximab-based chemotherapy. Overall response rate was 78.4%, with 13.8% clinical CR, 64.6% PR, and 21.6% failure/stable disease. 14 pts (12%) underwent stem cell transplantations, 8 had maintenance therapy ongoing (ofatumumab, alemtuzumab, or lenalidomide). With regards to factors defining high-risk relapse, distribution of salvage therapies was as follows: As expected, a second course of FCR was seldom used in high-risk patients. Among ultra-high risk patients, 30.3% received R-benda, 11.3% Alem-based Rx, 32% R-CHOP and 18% the miscellaneous regimens described above. After second-line therapy, median PFS was 12 months, median TTNT was 14mo, and median OS was 36mo (20 deaths). On univariate analysis, complex karyotype (p=0.04) but not del17p (p=0.1), PFS<24mo (p=0.028) and TTNT<24mo (p=0.04) correlated with OS. Regarding treatment, OS was significantly improved in R-bendamustine-treated patients, as compared to alem-based or CHOP regimen (p=0.01). Most importantly, patients who received an allogeneic transplant benefited from significantly prolonged OS (at 4y, 70% vs 40%, p=0.03). Of note, only one patient treated with R-benda received allotransplant. Conclusions: This study shows that there are no consensus for second line therapy after FCR. Second line trials after FCR therapy are warranted. Definition of high-risk subsets of patients at relapse after FCR is of upmost importance in the management of CLL, to compare second-line strategies. Our data suggest that R-bendamustine is an efficient regimen even in high-risk patients (complex karyotype, PFS<24mo, TTNT<24mo). These data are important since this immunochemotherapy is now used as the backbone for combination with new compounds (ibrutinib, GS1101, GDC-199). Disclosures: Aurran-Schleinitz: Roche: Honoraria.

Abstract Introduction: MM remains incurable but therapeutic advances has resulted in improved overall survival (OS) particularly for younger pts who are eligible for ASCT. Regardless OS improvements have been heterogeneous and it is well known that relapse within one year of ASCT is an independent negative prognostic factor. A particularly worse subgroup is pts who relapse and die of MM within a year of ASCT. There is limited data describing this subgroup of pts, the risk factors associated with their early relapse post ASCT and characteristics at relapse. Objective: Describe patient and disease related characteristics among MM pts who underwent ASCT and died of relapsed MM within the first year post ASCT in the era of novel agents. Methods: Pts were identified from the Leukemia/BMT Program of B.C. database, underwent ASCT between January 1st 2007 and July 31st 2016 and died of MM related causes within 365 days post ASCT. During this time period bortezomib (BORT) and lenalidomide (LEN) were available as second line therapy and BORT was available as induction pre-transplant for defined circumstances including high risk cytogenetics. Out of 752 ASCTs, 702 were performed as a part of initial therapy. The remaining ASCTs were performed as salvage or were the second of planned tandem ASCTs. Among the remaining 702 pts 37(5.3%) died within the first 365 days post ASCT. Of the 37 pts, 32 died from MM and related causes, 2 died of TRM from ASCT and 3 died from other causes not related to MM or ASCT. The 32 pts (4.6% of the total) who died of MM and related causes were matched with 64 controls (2:1 ratio) who were selected randomly from the remaining patient cohort and matched for age, gender, and year of transplantation. Results: There was no difference in Age at diagnosis (Median: case 61 VS control 60, P= .97) or gender (Male case 40.6% VS control 35.9%, P= .66). There was no significant difference in the prevalence of anemia, renal dysfunction, or hypercalcemia between both groups at diagnosis (table). Pts who died within the first year of ASCT had a more advanced stage at diagnosis compared to the control group (ISS Stage III: 53.1% vs 18.8%, P= .003). BORT based induction therapy was used in 84.4% of the cases compared to 53.1% in the control group, P= .001. The majority of pts in both groups had partial response or better to frontline therapy (Cases: 81.2% VS Controls 79.7%, P= .5). Only 9.4% of cases and 4.7% of controls had evidence of disease progression at the time of ASCT. High risk cytogenetics (t(4;14), t(14;16), or del 17p) were significantly more prevalent among pts who died within the first year post ASCT compared to the control (58.82% vs 31.67%, P= .009). There was no difference in the monoclonal protein subtype between the cases and controls, P= .55. The median time from ACST to disease relapse was 118 days (40-319) for the case group compared to 511 (107-1958) in the control group. Within the case group, 19 (59.3%) received LEN based therapy as second line therapy and 9 (28.1%) received BORT based therapy. Three patients (9.37%) were not candidates for any further therapy due to acute illness (2 sepsis, 1 subdural hemorrhage) related to fulminant MM relapse and one patient (3.1%) decided not to proceed with therapy due to functional decline. Overall, 17 pts (53.1%) received both BORT and LEN during the disease course, 12 (37.5%) received BORT only, 2 (6.25%) received LEN only and one received neither (3.1%). At the time of disease relapse, 9 (28.1%) had Hb level <85 g/l, 1 (3.1%) ANC<1000/mm3, 9 (28.1%) Plt <50/mm3, 9 (28.1%) GFR <20 ml/min, and 20 (62.5%) had at least one abnormal value (Hb, ANC, Plt, or Cr) and were not candidates for inclusion to clinical trials. Median OS (months) was Case 7.3 vs Control 63.8, P<.001. Conclusion: Approximately 5% of pts with MM who are ASCT eligible will die of MM within the first year post transplant. High risk cytogenetics (t(4;14), t(14;16), or del 17p) and advanced stage disease (ISS III) are risk factors for early mortality post ASCT for MM pts. These patient who relapse early typically have fulminant relapse with hematological and biochemical parameters outside of the range which would allow them to be enrolled on clinical trials and/or results in challenging standard of care management. Even in the era of novel agents, such pts do particularly poorly and represent a true unmet need in the treatment of MM. Further studies to understand the biology of their MM is required for identifying more potent therapeutic targets and protocols. Disclosures No relevant conflicts of interest to declare.

With the advent of the acquired immunodeficiency syndrome (AIDS), the therapeutic importance of pentamidine isethionate has increased greatly. This review summarizes the pharmacology, clinical experience in the treatment of Pneumocystis carinii pneumonia, and toxicity of pentamidine. Data are conflicting as to whether pentamidine is more or less effective than trimethoprim-sulfamethoxazole (TMP-SX) for the treatment of P carinii pneumonia in individuals with AIDS, but due to its toxicity and expense, it is considered as second-line therapy for P carinii pneumonia by many authorities. Hypoglycemia has been encountered in up to 27%, and nephrotoxicity in 25%, of treatment courses with pentamidine. In an attempt to circumvent the toxicities associated with parenteral administration, aerosolized delivery has been evaluated for both therapy and prevention of P carinii pneumonia. Aerosolized pentamidine, on the basis of early clinical results, convenience, and low toxicity, is being used extensively to prevent P carinii pneumonia in individuals at high risk. Relapses occur, however, and pneumothorax may be more common in those using this form of prophylaxis. Aerosolized pentamidine should not be used as sole therapy for acute P carinii pneumonia.

Abstract The FCR regimen is the most active treatment program in CLL, with 72% of frontline patients achieving a complete remission (CR) lasting a median of 7 years. However, most patients are not cured and will eventually relapse with CLL. In order to evaluate how these patients should be subsequently managed, we analyzed our institutional experience with 300 patients treated with frontline FCR (Blood 112:975). After a median follow-up of 6 years, 116 patients (39%) had failed FCR therapy with 13 primary refractory disease and 103 relapses from partial remission (PR), nodular PR (nPR) or CR. Compared with patients in ongoing remission, relapsed/refractory patients had more adverse baseline characteristics including a greater proportion with performance status ≥ 1 (71% vs 53% p=0.002), elevated β2m (54% vs 36% p=0.002), white cell count ≥ 150 x 10^9/L (25% vs 12% p=0.003), unmutated IgVH (81% vs 44% p&lt;0.001) and ZAP-70 positivity (78% vs 49% p&lt;0.001). The aim of the current analysis was to determine the duration of survival (OS) following second-line therapy in 97 patients who had completed salvage treatment. The median follow-up was 32 (range 3 – 69) months, and the median OS (mOS) was 32 months. Characteristics associated with favorable OS were: (1) previous best response to FCR of nPR/CR lasting ≥ 18 months (mOS 47 months, vs 13 months for primary refractory disease, PR or nPR/CR lasting &lt;18 months p=0.002); (2) β2m &lt; 3.0 mg/L (mOS not reached, vs 17 months p=0.0003) and (3) platelets ≥ 100x10^9/L (mOS 47 months, vs 15 months p=0.004). Poor risk cytogenetic abnormalities were common at FCR failure: among 38 assessable patients, 7 (18%) had 17p- and 18 (47%) had 11q- by conventional karyotyping and/or FISH. Although patients with 17p- or 11q- had an inferior survival, this survival disadvantage was confined entirely to those who also had an elevated β2m ≥ 3.0 mg/L. Surprisingly, patients relapsing after durable FCR remissions (≥ 5 years) and patients with slowly progressive relapse (time to salvage ≥ 12 months after FCR failure) had similar OS as their more adverse counterparts (p=0.76 and 0.86 respectively). A prognostic model comprising β2m and platelet count effectively divided patients into low, intermediate and high risk categories with mOS of &gt;45, 32 and 13 months respectively (p&lt;0.0001). Patients received treatment chosen at the discretion of individual treating physicians and the CR rate of second-line therapy were: FCR (n=30), 17%; rituximab (n=25), 4%; alemtuzumab ± rituximab (n=16), 31%; FCR & alemtuzumab (CFAR, n=9), 56%; lymphoma-type chemotherapy (n=5), 0%; other treatment (n=12), 0%. The CR rate for CFAR was significantly higher than that of FCR (p=0.03), although the median remission duration (30 vs 20 months) and OS (44 vs 32 months) were similar (p=0.87 and 0.51 respectively). None of the regimens showed a significant survival benefit. Allogeneic stem cell transplantation (SCT) was performed in 27 (28%) patients at a median of 15 months after first salvage. Patients receiving SCT had a significantly superior OS than those who did not undergo SCT (not reached vs 30 months, p=0.03). Of the 14 patients surviving for more than four years, 11 (79%) had undergone a SCT. Patients who fail FCR therapy had high risk disease features including elevated β2m, unmutated IgVH and ZAP-70 positivity, and most had adverse cytogenetic findings at relapse. Results of salvage therapy in this group were poor with a median survival of less than three years. The majority of long-term survivors had received allogeneic stem cell transplantation.
