Abstract Cytogenetic high risk AML (abn 3q26, abn 11q23, −5/5q-, −7/7q- and complex) has a dismal prognosis with a two year overall survival (OS) below 20% even in young patients. Attempts to improve survival by intensifying consolidation chemotherapy have so far failed. In the two OSHO protocols AML 96 and AML 2002, we investigated the role of allogeneic HCT in these patients. A total of 708 patients have been entered into the two studies between 1997 and the present. The first protocol (AML 96) compared two different schedules employing identical total dosages of intermediate AraC and Idarubicin. The second protocol (AML 2002) studied the role of two different induction therapies in patients failing to reach CR after the first induction therapy. In patients with cytogenetic high risk AML, the search for a donor (either familial or, if none available, then unrelated) was initiated as soon as possible. Allogeneic HCT was scheduled either after induction or after first consolidation therapy. HCT was performed after conditioning with cytoxan and 1200 cGy total body irradiation followed by GvH-D prophylaxis with cyclosporine and methotrexate. Of the 708 patients, 138 (19,5%) had high risk cytogenetics and 77 (55,8%) of these went into remission after one or two cycles of induction chemotherapy. Of these 77 patients, 54 were alive and in CR after the first consolidation therapy and were allocated to either related (n=12) or unrelated (n=21) HCT or, if no compatible donor was available, to a two courses of chemotherapy (n=21). Median age of the patients was 36 (range 17–51) years, 46 years (range 23–59) years and 49 (range 16–60) years for patients receiving related HCT, unrelated HCT and chemotherapy respectively. Data were analysed as intention to treat.LFS at 3 years was 67 ± 14% after related and 44 ± 14 % after unrelated HCT, but decreased to 11 ± 7% in patients receiving chemotherapy. Allogeneic HCT results were significantly better than the results of chemotherapy with p-values of 0.005 and 0.002 for related vs. chemotherapy and unrelated vs. chemotherapy respectively. Major differences in relapse incidences were seen between the three groups, with the lowest RI at 3 years after related HCT 26±0.13%, followed by unrelated HCT 48±15% and by chemotherapy 89±8% (p=0.003 and p=0,0006 for chemotherapy vs. related or unrelated HCT). Transplant related mortality at 3 years was 10±9%, 14±10% and 6±6% for patients receiving HCT from related donors, from unrelated donors and chemotherapy, respectively. Conclusions: From the results observed in the two prospective, multicenter studies we conclude that consolidation with allogeneic HCT is superior to chemotherapy in younger patients with high risk cytogenetics. While no differences in TRM were seen between the three treatment arms, a lower relapse incidence after related and unrelated HCT contributed to the improved OS.

7003 Background: Even after reaching initial CR, most AML patients > 60 years relapse within 2 years of diagnosis. Cytogenetic high risk AML (abn 3q26, abn 11q23, -5/5q-, -7/7q- and complex) has an even worse prognosis. Attempts to improve survival by intensifying consolidation chemotherapy have so far failed. We investigated the role of allogeneic HCT in comparison to chemotherapy among patients with high risk cytogenetics entered into the OSHO AML 97 protocol. Methods: Initial treatment consisted of a course of induction therapy (AraC 2 g/m2 iv on day 1,3,5,7 + mitoxantrone 10 mg/m2 iv day 1 –3, repeated once in case of PR) followed by one consolidation course (AraC 240 mg/m2 iv day 1 –5 + mitoxantrone 10 mg/m2 iv day 1 –2). Patients in CR1 after the consolidation I were either treated with an additional consolidation therapy or with an allogeneic HCT from related (n=2) or unrelated (n=10) donors. Transplant patients were conditioned with fludarabine and TBI 200 cGy and immunosuppressed with cyclosporine and mycofenolate mofetil. Results: A total of 347 patients are evaluable. Of 105 (33%) patients with high-risk cytogenetics, 53 (50%) went into remission after one or two cycles of induction chemotherapy. Of these 53 patients, 42 received consolidation I and 35 patients were available for either consolidation II (n=23) or HCT (n=12). Median age of the patients receiving chemotherapy was 64 (range 61–77) years and that of the transplant patients was 64 (range 61–68) years. LFS at 4 years was 42 ± 14% after HCT and 15 ± 8% after chemotherapy. Major differences in relapse incidences were seen between the two groups, with the lowest RI at 4 years after HCT (36 ± 15%) followed by chemotherapy (85±8%, p<0.04). Treatment related mortality at 4 years was 35±17% and 0±0% for patients receiving HCT and chemotherapy, respectively (p<0.05). Conclusions: From these results, we conclude that consolidation with allogeneic HCT after minimal conditioning is superior to chemotherapy even in older patients with high risk cytogenetics. While differences in TRM were seen between the treatment arms, a lower relapse incidence after related and unrelated HCT contributed to the improved LFS. No significant financial relationships to disclose.

Results of the study related to polymorphism of ACE gene (rs1799752)‎, integrin αIIbβ3, and CSK gene (rs1378942) influencing development of arterial hypertension in young patients with metabolic syndrome are presented. Hypertension as a component of the metabolic syndrome was detected in 15.0% of young patients. Prevalence of mutant alleles of the studied genes among the examined patients was quite high, so homozygous DD genotype was found in 21.6%, and mutant D allele of the ACE gene in 47.4%. A high risk of hypertension in patients with MS was detected in carriers of the T allele of the CSK (rs1378942) gene – 54.8%, which was most often observed in a combination of polymorphic ACE and CSK gene loci (p = 0.0053).

The dismal prognosis of pediatric and young adult patients with high-risk rhabdomyosarcoma (RMS) underscores the need for novel treatment options for this patient group. In previous studies, the tumor-associated surface antigen ERBB2 (HER2/neu) was identified as targetable in high-risk RMS. As a proof of concept, in this study, a novel treatment approach against RMS tumors using a genetically modified natural killer (NK)-92 cell line (NK-92/5.28.z) as an off-the-shelf ERBB2-chimeric antigen receptor (CAR)-engineered cell product was preclinically explored. In cytotoxicity assays, NK-92/5.28.z cells specifically recognized and efficiently eliminated RMS cell suspensions, tumor cell monolayers, and 3D tumor spheroids via the ERBB2-CAR even at effector-to-target ratios as low as 1:1. In contrast to unmodified parental NK-92 cells, which failed to lyse RMS cells, NK-92/5.28.z cells proliferated and became further activated through contact with ERBB2-positive tumor cells. Furthermore, high amounts of effector molecules, such as proinflammatory and antitumoral cytokines, were found in cocultures of NK-92/5.28.z cells with tumor cells. Taken together, our data suggest the enormous potential of this approach for improving the immunotherapy of treatment-resistant tumors, revealing the dual role of NK-92/5.28.z cells as CAR-targeted killers and modulators of endogenous adaptive immunity even in the inhibitory tumor microenvironment of high-risk RMS.

The oncogene BRAFV600E is the most frequent genetic event in papillary thyroid carcinoma (PTC) but its prognostic impact still remains to be elucidated. We evaluated a representative series of 67 individuals with PTC who underwent total thyroidectomy. BRAF-positive tumours correlated with early recurrences (32% vs 7.6%; P=0.02) during a median postoperative follow-up period of 3 years. Interestingly, within the recurrences, a significant majority had negative radioiodine (131I) total body scans, predicting a poorer outcome as treatment with 131I is not effective. This last observation led us to investigate the role of BRAFV600E and the MEK-ERK pathway in thyroid dedifferentiation, particularly in Na+/I− symporter (NIS) impairment, as this thyroid-specific plasma membrane glycoprotein mediates active transport of I− into the thyroid follicular cells. A subset of 60 PTC samples was evaluated for NIS immunoreactivity and, accordingly, we confirmed a significant low NIS expression and impaired targeting to membranes in BRAF-positive samples (3.5% vs 30%; P=0.005). Furthermore, experiments with differentiated PCCl3 thyroid cells demonstrated that transient expression of BRAFV600E sharply impaired both NIS expression and targeting to membrane and, surprisingly, this impairment was not totally dependent on the MEK-ERK pathway. We have concluded that BRAFV600E is a new prognostic factor in PTC that correlates with a high risk of recurrences and less differentiated tumours due to the loss of NIS-mediated 131I uptake.

Bacterial pneumonia is one of the most prevalent infectious diseases and has high mortality in sensitive patients (children, elderly and immunocompromised). Although an infection, the disease alters the alveolar epithelium homeostasis and hinders normal breathing, often with fatal consequences. A special case is hospitalized aged patients, which present a high risk of infection and death because of the community acquired version of the Streptococcus pneumoniae pneumonia. There is evidence that early antibiotics treatment decreases the inflammatory response during pneumonia. Here, we investigate mechanistically this strategy using a multi-level mathematical model, which describes the 24 first hours after infection of a single alveolus from the key signaling networks behind activation of the epithelium to the dynamics of the local immune response. With the model, we simulated pneumonia in aged and young patients subjected to different antibiotics timing. The results show that providing antibiotics to elderly patients 8 h in advance compared to young patients restores in aged individuals the effective response seen in young ones. This result suggests the use of early, probably prophylactic, antibiotics treatment in aged hospitalized people with high risk of pneumonia.

Abstract Purpose: In patients with acute myeloid leukemia (AML) differential indications for matched sibling and unrelated hematopoietic stem cell transplantation (HCT) are considered and arbitrary age limits for HCT exist. We sought to determine whether donor type is a prognostic factor in elderly patients in the era of high-resolution DNA-based HLA-typing. Patients and Methods: We performed a retrospective cohort analysis in patients with AML older than 50 years who had received an allogeneic HCT between 1995 and 2005. If available, DNA from donors and recipients of unrelated HCT was used for molecular retyping in order to get information on HLA-A, -B, -C, -DRB1 and DQB1 at the allele-level. Donor-recipient pairs with fully matched donors or one mismatch out of ten alleles were considered well-matched. Results: We identified 368 patients with cytogenetic intermediate or high risk AML who fulfilled the entry criteria. The median age of this cohort of patients was 57 years (range 50 to 73 years). 46% of patients had matched sibling donors, 3% related non-sibling donors, 41% well-matched unrelated donors and 10% poorly matched unrelated donors. In the respective period the percentage of patients with unrelated donors increased from 0% in 1995 to 64% in 2004. High risk features were a history of prior myelodyplasia in 34% of patients, poor risk cytogenetic abnormalities in 33% of patients and a disease status beyond CR1 in 62% of patients. 72% of patients received reduced-intensity conditioning regimens. Peripheral blood stem cells were used as graft in 84% of patients. In multivariate analysis disease status at HCT (p&lt;0.001) and cytogenetic risk (p&lt;0.001) proved to be highly significant predictors, both, for EFS and OS. Whereas, the relative risk of a patient with a well-matched unrelated donor compared to a sibling donor was 0.9 (95% CI, 0.6 to 1.2) for EFS and 1.0 (95% CI, 0.7 to 1.4) for OS. In subgroup analyses EFS was better in AML patients with cytogenetic high risk disease beyond first remission (CR1) (p=0.0147) who had well-matched unrelated donors compared to those with sibling donors and not inferior in any of the other subgroups. Conclusions: Allogeneic HCT from matched unrelated donors (&gt;=9/10) should be considered equivalent to sibling HCT in terms of survival for patients above the age of 50 years with intermediate or high risk AML. In advanced stages of AML with high risk cytogenetics patients with matched unrelated donors may even have better EFS compared to those with sibling donors.

Abstract Abstract 1924 Innovative therapeutic approaches are needed to reduce the morbidity and high relapse rates in patients with advanced AML or high-risk MDS following myeloablative hematopoietic cell transplantation (HCT). Success with stable donor chimerism and low toxicity following infusion of allogeneic peripheral blood stem cells (PBSC) with reduced-intensity regimens affords an opportunity to induce a graft-versus-leukemia (GVL) effect with minimal acute morbidity. GVL effects, however, appear to be most potent in patients with low tumor burden at the time of HCT. In an attempt to improve outcomes, we previously transplanted 58 patients older than age 50 with advanced AML (beyond first remission) or high-risk MDS (≥5% marrow blasts at the time of HCT) in a Phase I trial using 131I-labeled anti-CD45 antibody (BC8) in conjunction with fludarabine (FLU) and 2Gy total-body irradiation (TBI). Data from this study suggested that 131I-anti-CD45-targeted radiotherapy could be safely integrated into a reduced-intensity conditioning regimen for older, high-risk patients with AML or MDS yielding encouraging survival outcomes. These results prompted us to evaluate a similar strategy in younger patients (ages 16–50) with advanced AML or high-risk MDS who may not be able to receive a high dose HCT conditioning regimen. In this phase I dose–escalation trial 14 patients received a dose of 131I-BC8 that delivered 10–27 Gy of targeted radiation to the healthy organ receiving the highest dose combined with FLU (30 mg/m2 daily for 3 days), 2 Gy TBI, and HLA-matched related (n = 7) or unrelated (n = 7) PBSC grafts. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and mycophenolate mofetil. The 131I radiation dose was escalated until the maximum planned dose of 28 Gy was reached without any appreciable dose limiting toxicity. The median patient age was 39.5 (range, 23.8–49.7) years. Thirteen patients had AML, with 9 patients in second complete remission, 3 with primary refractory disease, and 1 in active relapse. One patient had advanced CMML with >5% blasts. Treatment with the 131I-BC8 Ab/FLU/TBI regimen produced a complete remission in 7 patients (50%), and 11 of the 12 evaluable patients had 100% donor CD3+ and CD33+cell engraftment by day 28 after HCT; an additional patient had 79% CD3 and 82% CD33 positive donor marrow cells at day 28. The absolute neutrophil count surpassed 500/μL at a median of 15 (range, 13–22) days. Self-sustained platelet levels of 20,000/μL were reached at a median of 11 (range, 11–27) days after HCT. Five patients (36%) are surviving relapse-free 46 to 99 months (median 87 months) after HCT. Seven patients (50%) have died, with five patients relapsing 0.9 to 45 months after HCT. No non-relapse mortality occured by day 100; however, two patients died 14 and 18 months after HCT of cardiomyopathy and GVHD complications, respectively. This study demonstrates that, in addition to a standard reduced intensity conditioning regimen, an average of 27 Gy of targeted 131I radiotherapy can be delivered to bone marrow, an average of 20Gy to the liver, and an average of 84 Gy to the spleen without a marked increase in day 100 mortality for younger patients. This strategy may thus provide a reasonable alternative for patients with high-risk AML/MDS who may not be able to tolerate a high dose conditioning HCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: Multiple myeloma remains incurable despite impressive array of available novel agents and therapeutic strategies. Allogeneic hematopoietic cell transplantation (HCT) remains the only potentially curative option for patients with multiple myeloma but it is limited by its toxicities. We previously reported initial result of a phase 2 study of upfront allogeneic HCT in myeloma patients achieving at least very good partial response (VGPR) after initial therapy (Nishihori, et al. ASH 2013 abstract 3390) and here we report more mature results after a median follow up of 3 years. Methods: Twenty seven myeloma patients received allogeneic HCT between 01/2010 and 02/2015 at Moffitt Cancer Center (NCT 00948922). Eligible patients were age ≤ 60, achieving first ≥ VGPR or complete response (CR), and have 8/8 HLA-matched related or unrelated donors. Conditioning regimen consisted of fludarabine 30 mg/m2 for 4 days (days -6, -5, -4, and -3) and melphalan 70 mg/m2 for 2 days (days -4 and -3) followed by a single dose of bortezomib 1.3 mg/m2 on day -3 (Flu/Mel/Vel regimen). GVHD prophylaxis was initially left to the discretion of physicians but later modified to only tacrolimus/methotrexate. No maintenance therapy was prescribed after allogeneic HCT. Results: The median age at transplant was 50 (range, 25-58) years. Disease status at the time of allogeneic HCT was VGPR (n=17: 63%) and CR/stringent CR (n=10: 37%). All patients received unmanipulated peripheral blood stem cell grafts from HLA-matched related donors (n=14) or HLA-matched unrelated donors (n=13). Graft-versus-host disease (GVHD) prophylaxis was tacrolimus plus either methotrexate (n=19: 70%), or mycophenolate mofetil (n=4), or sirolimus (n=4). All patients achieved neutrophil engraftment with a median of 15 (range, 11-19) days. Platelet engraftment was achieved with a median of 17 (range, 13 - 35) days and 2 patients did not recover platelets. The cumulative incidences of grades II-IV and grades III-IV acute GVHD at day 100 were 63.6% (95% confidence interval (CI): 43.1-81.1) and 19.6% (95%CI: 5.4-39.9), respectively. The cumulative incidence of moderate to severe chronic GVHD was 56.4% (95%CI: 36.3-75.5) at 1-year. The cumulative incidences of transplant-related mortality at day 100, 1 year and 2 years were 7.4% (95%CI: 0.8-20.0), 11.1% (95%CI: 2.7-25.4), and 11.1% (95%CI: 2.7-25.4), respectively. Progression-free survival estimates at 1, 2, and 3 years were 74.1% (95%CI: 53.2-86.7), 65.1% (95%CI: 43.3-80.2), and 65.1% (95%CI: 49.9-87.5), respectively. With a median follow up of 39 months for surviving patients, overall survival estimates at 1, 2 and 3 years were 85% (95%CI: 64.9-94.1), 75.4% (95%CI: 52.6-88.3), and 69.1% (95%CI: 53.8-93.5), respectively. Conclusions: The results of the this phase 2 trial of upfront allogeneic HCT with fludarabine/melphalan/bortezomib (Flu/Mel/Vel) conditioning are promising and provide the rationale for reasonable potentially curative option to younger and fit patients who are eligible for upfront intensive consolidation strategy. This approach may be potentially valuable for those with high-risk myeloma and a multicenter study is currently being conducted (BMT CTN protocol 1302:NCT02440464).
