Abstract Introduction: Prolonged treatment of graft vs. host disease (GVHD) is extremely immunosuppressive. Local therapy with intra-arterial (IA) injection of steroids may induce remission with lower extent of systemic immune suppression. Here, we present our experience with IA treatment of gastrointestinal (GI) and/or hepatic steroid resistant/dependent GVHD with 2 consecutive protocols. Patients and methods: Thirty five patients (37 GVHD events (hepatic, n=15), (GI, n=16), (combined, n=6)) were treated with 53 IA sessions. Most side effects were minor. Results: We found that IA steroid therapy was associated with partial and complete remission among patients with steroid resistant/dependent hepatic or GI GVHD. Hepatic partial response was observed in 14 (66.6%) patients among whom 7 (33.3%) reached complete response. GI partial response was observed in 19 (86.4%) patients among whom 12 (54.4%) reached complete response. Early administration of the local therapy, female gender, myeloid basic disease, and a non-active status of the basic disease at the day of transplantation were found related for predicting a better response for the intra-arterial treatment. The use of high dose steroids in the hepatic IA protocol from was at least as good as intermediate dose steroids with methotrexate (table 1, figure 1) and may be safer. Conclusions: Intra-arterial catheter guided steroid therapy is safe and effective in steroid resistant/dependent GVHD. Hepatic artery treatment with methotrexate can be safely substituted with high dose IA methylprednisolone. Further research is warranted characterizing the patients benefit most.

Abstract Acute graft-versus-host disease (aGVHD) carries a major risk of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). The prognosis is poor if aGVHD does not respond to corticosteroid treatment. Recently, monoclonal antibodies such as daclizumab, a humanized monoclonal IgG1, and infliximab, a chimeric monoclonal antibody that binds the precursor of tumor-necrosis factor-alfa, have shown promising results in the treatment of corticosteroid-resistant aGVHD. The reported response rate to monoclonal antibody therapy in adults with aGVHD reaches as high as 67%. Data describing the efficacy of monoclonal antibodies in children with corticosteroid-resistant aGVHD are limited. We conducted a retrospective analysis to evaluate the efficacy of daclizumab and/or infliximab in children diagnosed with steroid-resistant aGVHD in the Hospital for Sick Children, Toronto, from July 2002 to December 2005. Corticosteroid-resistant aGVHD was defined as aGVHD which did not respond or worsened after a minimum of 5 days of corticosteroid therapy. Complete response was defined as full recovery without any signs of aGVHD; partial response was defined as improvement of aGVHD symptoms in at least one organ without worsening in other organs. Sixteen children were treated for aGVHD, thirteen of them had aGVHD grade 3 or 4. The organs involved were gut (n=6), skin (n=4), liver (n=2) and multi-organ involvement (n=4). Thirteen children were given daclizumab; one was treated with infliximab and 2 children with their combination. Fourteen children received a full course of monoclonal antibodies for aGVHD. An additional child died after the first dose (from multi-organ failure) and one child developed reactive arthritis attributed to daclizumab. Seven of the 14 children (50%) who completed treatment responded: 5 had complete response and 2 had a partial response. Nine out of the 16 children died during the study period: 8 due to Transplant Related Mortality (TRM) and 1 due to relapse; three children developed fatal fungal infection and one had fatal adenovirus infection during or shortly after monoclonal antibody treatment. Median length of follow up in the remaining 7 patients was 18 months. We conclude that monoclonal antibodies were effective in the treatment of children with corticosteroid-resistant acute GVHD. The risk for infection, mainly fungal, was high.

Abstract Introduction : Graft-versus-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation (BMT), resulting in death in the majority of steroid-resistant patients. In the past 15 years, we revolutionized the use of interventional radiology procedures in the field of stem cell transplantation. This study was aimed to assess the efficacy of regional intra-arterial steroid (IAS) treatment in the largest published cohort of patients with resistant/dependent hepatic and/or gastrointestinal (GI) GVHD. In total, 113 patients with steroid resistant or dependent grade 3-4 hepatic (n = 21), gastrointestinal (GI) (n = 62) GVHD or both (n = 30) were given intra-arterial treatment. Patients and methods: Patients with liver GVHD received IAS in hepatic artery and patients with gastrointestinal GVHD received IAS in the superior and inferior mesenteric as well as the internal iliac arteries. Patients with pronounced upper GI symptoms also received IAS to the gastroduodenal artery. In total 148 procedures were carried out (range 1-3 per patient). Results : Partial responses were observed in 33 out of 51 (65%) patients with hepatic GVHD, out of which (55%) had complete response. Median time to complete response was 45 days (range - 5 to 300 days). For GI GVHD complete responses were observed in 69 out of 92 (75%) and partial responses were observed in 76 out of 92 (83%). The median time to complete response was 20 days (range - 3 to 200 days ). As this is the largest published cohort of regional IAS therapy for GVHD, multivariate and univariate analysis was done in order to identify the patients with highest chance of response. Conclusions : Regional treatment of severe GVHD with IAS treatment is effective and safe. GI treatment is more effective than intrahepatic treatment. Early administration of isolated intra-arterial therapy in high-risk patients may further improve the outcome and reduce untoward effects of prolonged systemic immunosuppressive treatment. Figure 1.

Abstract Background  Constrictive pericarditis (CP), although an uncommon cause of heart failure, requires specialist multidisciplinary input and multi-modality imaging to identify the underlying aetiology and treat potentially reversible causes. Case summary  We report the case of a 74-year-old gentleman referred for assessment of progressive exertional dyspnoea and peripheral oedema, 30 months following treatment of acute myeloid leukaemia with high-dose chemotherapy and allogeneic stem cell transplantation. Clinical examination and cardiac imaging revealed a small pericardial effusion and pericardial thickening with constrictive physiology; however, no aetiology was identified despite diagnostic pericardiocentesis. The patient required recurrent hospital admissions for intravenous diuresis, therefore, following multidisciplinary discussions, surgical partial pericardectomy was performed. Histology suggested graft-vs.-host disease (GvHD) and post-operatively, the patient improved clinically. Following immunomodulatory therapy with ruxolitinib for both pericardial and pulmonary GvHD, his functional status improved further with no subsequent hospital admissions. Discussion  Although pericardial disease in cancer patients is common, CP is unusual. Determining the underlying aetiology is important for subsequent management, and here, we describe the use of multi-modality imaging to diagnose a rare cause, GvHD, which responded to surgical treatment and immunomodulatory therapy.

Abstract Abstract 3168 INTRODUCTION: Steroids are the first line treatment for Autoimmune Hemolytic Anemia (AHA) and Immune Thrombocytopenic Purpura (ITP). Second line treatments for patients with partial reponses or steroid dependence are controversial and have changed during the last decades. Several authors have proposed the use of Rituximab in these patients although published data are still sparse. OBJECTIVES: We reviewed the medical records of all the patients treated in our hospital with Rituximab in order to evaluate the response rate and security of this treatment. MATHERIALS AND METHODS: We included in the study all the patients older than 18 years with diagnoses of Immune Thrombocytopenia or Autoimmune Hemolytic Anemia treated with Rituximab. Patients with oncologic diseases that required specific chemotherapy apart from AHA or ITP were excluded. Rituximab was administered at a dose of 375mg/m3 weekly for 4 weeks. In patients with AHA we assessed the response according to the following criteria: complete response a hemoglobin level higher than 12 g/dl without hemolysis (normal bilirubin, LDH and haptoglobin) and partial response at least 2g/dl increase from the basal hemoglobin level with improvement in the hemolysis parameters. In patients with ITP we defined complete response as >100.000 platelets/mm3 and partial response >50.000 platelets/mm3. In both cases patients should be tapering steroids (less than 10mg/day of prednisone) and without transfusions. RESULTS: We performed 55 treatments with Rituximab in 37 pts., 19 AHA (12 cold hemolytic anemia) and 18 ITP. The median age was 60 years (26 – 86) and 31 pts. were female. Five patients had other autoimmune diseases (lupus, sjogren, autoimmune hepatitis), and six patients had an underlying onco-hematologyc disease (CLL, indolent lymphoma). All patients had been treated with steroids before and most of them had also received azathioprine, cyclophosphamide or gamaglobuline. The median of previous treatments was 3. Eight patients had undergone also splenectomy. The reason for the treatment was steroid dependence in 16 patients, partial response 6 patients and no response to previous treatment in 15 patients. The overall response rate was 79% for AHA and 94% for ITP, with 8pts (42%) and 13pts (72%) achieving a complete response and 7pts (37%) and 4pts (22%) achieving a partial response respectively. The median time to the complete response was 14 days for ITP and 28 days for AHA. The treatment was well tolerated with only one infusion related serious adverse event and one pulmonary thromboembolism during the period of treatment. Fourteen patients relapsed (8 AHA and 6 PTI). The response rate to Rituximab at relapsed for those patients that received a second or even third course of treatment were similar to the observed before. The median time of follow up was 50 months with and event free survival at 1 year of 34% (median 11,9 months) for AHA vs. 60% for PTI (median 38 months) (p 0,23). The overall survival at 5 years was 39% (median 53 months) vs. 86% (median not reached) (p 0,18) respectively. Seven patients with AHA and 2pts with ITP died, mostly of infectious complications. CONCLUSIONS: Rituximab is an effective treatment for ITP and AHA patients with no response to previous treatments or corticoid dependence. There were few serious adverse effects related to the treatment with Rituximab itself. The mortality rate was higher in patients with AHA although it wasn`t statistically significant. The main cause of death was related to infectious complications but most of the patients had a long history of immunosuppression treatment. Patients who relapsed and were treated again with rituximab had very good response rate. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 3964 Introduction: Monitoring multiple myeloma (MM) patients is required to help guide therapy and assess response. Currently the most commonly employed tests to monitor MM patients include serum protein electrophoresis (SPEP), immunofixation (IFE), 24hr urine and serum free light chain (FLC) analysis. Whilst electrophoretic tests are adequate for IgG MM, they may be inadequate for IgA MM where the monoclonal immunoglobulin co-migrates with other serum proteins (∼60% of cases). Recently the inclusion of FLC testing to identify patients in stringent complete response (sCR) has been recommended. Novel nephelometric reagents have become available that can quantify IgA kappa and IgA lambda immunoglobulins (HLC) in serum. Here we assess the use of these tests at maximum response to detect residual disease and comment on the prognostic value of sCR. Patients, materials and methods:196 IgA MM patient samples recruited from the MRC IX trial were assessed at maximum response. Briefly, patients were randomised on to intensive (I: induction therapy with CVAD or CTD followed by high-dose melphalan and ASCT) and non-intensive (NI: clodronate or zoledronic with MP or CTDa) arms. Median age was 59 years (range: 37–71) and 74 years (range: 65–89) for patients in the I and NI arms, respectively. 31% patients in the I arm and 39% in the NI arm presented with stage III disease. Samples were taken 3 months after autologous stem cell transplant or maximum response and analysed nephelometrically using serum FLC and HLC immunoassays. Ratios for both FLC and HLC were compared to normal ranges (FLC normal ratio= 0.256–1.65, IgAkappa/IgAlambda normal ratio=0.8–2.04). Additionally, isotype-matched immunoparesis was described as <0.48 g/L IgAkappa and <0.36g/L IgAlambda. Results were compared to SPEP, IFE and total immunoglobulin assays (where immunoparesis was described as <6g/L IgG and <0.4g/L IgM). 2-year progression free survival (PFS) was determined using Kaplan Meier analysis (SPSS v 19.0). Results: 3 months post-therapy, patient responses were: I arm: progressive disease (PD): n=1(<1%); minimal response (MR): n=1(<1%); partial response (PR): n=10(8%); very good partial response (VGPR): n=35(29%); complete response (CR): n=13(11%); sCR: n=58(48%); for two patients no data was available; NI arm: progressive disease (PD): n=3(4%); stable disease (SD): n=5(7%); MR: n=10(13%); PR: n=31(41%); VGPR: n=16(21%); CR: n=11(15%). Within the 2-year follow up, 41% patients in the I arm and 46% in the NI arm relapsed. Median PFS was not significantly different between the two arms (not reached v 7 months, p=0.65). Response (3VGPR) was not associated with PFS in either arm (I, p=0.717; NI, p=0.236). By contrast, achievement of a sCR (p=0.013) was significantly associated with longer PFS in the I arm and tended towards significance in the NI arm (p=0.063). An abnormal HLC ratio was associated with shorter PFS in both arms (I, p=0.002; NI, p=0.032). In all patients achieving a 3VGPR, an abnormal HLC ratio was associated with shorter PFS (p>0.0001). Similarly, in patients achieving a 3CR an abnormal HLC ratio was also associated with shorter PFS (p=0.04). Furthermore, patients achieving a CR where both FLC and HLC ratios were normal had a significantly longer PFS than those with an abnormal FLC or HLC ratio (median PFS not reached v 18 months, p=0.007). Isotype-matched immunoparesis was associated with shorter PFS in all patients achieving a CR (p=0.061). By contrast, systemic immunoparesis of either IgG or IgM immunoglobulins were not associated with PFS (p=0.525 and p=0.964, respectively). Discussion: Novel therapies have dramatically improved MM patient outcomes, however improvements in the assessment of those outcomes has not followed a similar trajectory. Here we present data suggesting immunoglobulin HLC ratios may be better markers of residual disease than electrophoretic methods. In addition a response category based on normalisation of both FLC and HLC ratios may be more valuable than sCR. Finally, the identification of isotype matched immune reconstitution as a marker of outcome suggests a preferential suppression of immunoglobulin production not previously reported. Conclusion: Normalisation of the FLC and HLC ratio at maximum response is a better assessment of disease than IFE. Further work is required to validate these results and to assess FLC and HLC ratios against multi-parametric flow cytometry. Disclosures: Young: Binding Site: Employment.

Abstract Introduction - Oligoclonal bands (OB) are monoclonal proteins distinct from those originally identified in the multiple myeloma (MM) diagnosis. Some authors consider that appearance of these bands confers a better prognosis and may be linked to immune reconstitution. There is no data of the exact prevalence of OB emergence in patients with very good partial response (VGPR) or better after different treatment schedules. Objectives - To determine the prevalence of OB in MM patients treated with or without high-dose chemotherapy that obtained at least VGPR and its prognostic value. Methods- This is a retrospective and prospective cohort study. Data were collected from records of patients that achieved at least VGPR to identify the OB emergence. Subsequently, new sample collections from the positive patients were made in order to monitor the progress and duration of the maintenance of these bands. Results-Median follow-up was 42m and 101 patients were included. Median age was 58y (29-87) and 55% were male. IgG was the most frequent component (60%). Durie-Salmon IIIA/B was identified in 92% of the population; ISS was 33% in stage I, 30% in stage II, and 31% in stage III. The prevalence of OB identified by SPE and IF was 50.5% (51 cases), with a higher prevalence in those who underwent transplantation and those who achieved complete response (p=0.00139 and p=0.0368, respectively). Progression free survival (PFS) was longer in the OB group (45.4m x 34.7m p = 0.0075). Conclusion - The OB prevalence in this population was 50.5% and oligoclonality resulted in a longer PFS.

Abstract [Background] Multiple myeloma (MM) is generally considered incurable. Recently, novel drugs, including bortezomib, have demonstrated a survival benefit for newly diagnosed MM patients compared with classical treatments. Complete response (CR) after treatment is known to be associated with superior progression-free survival. Thus, we prospectively evaluated the efficacy and safety of boretezomib + dexamethasone (BD) for patients with newly diagnosed MM, followed by autologous hematopoietic stem cell transplantation (ASCT). We added BD consolidation therapy to aim CR if CR was not achieved after ASCT. [Patients and methods] This clinical study prospectively recruited newly diagnosed MM patients eligible for ASCT between 2010 and 2012. Due to health insurance issues in Japan, two courses of high-dose dexamethasone (HD-DX) had been administrated prior to BD induction treatment until Nov. 2011, while BD was administrated as an initial induction treatment since Dec. 2011. BD induction treatment included 1.3 mg/m2 of bortezomib on days 1, 4, 8, and 11 with 20mg of dexamethasone on days 1, 2, 4, 5, 8, 9, 11, and 12. This BD induction cycle was repeated every 3 weeks for 4 courses. Thereafter, filgrastim-based mobilization and ASCT following high-dose melphalan administration was performed. If patients did not achieve CR after ASCT, BD consolidation therapy (bortezomib: 1.3 mg/m2 on days 1, 8, and 15; dexamethasone 20 mg/day on days 1-2, 8-9, and 15-16) every 4 weeks was added to target CR (Figure 1) (UMIN-CTR: UMIN000002442). [Results] The median observational duration among survivors was 1536 days (range: 464-2023) at this analysis. Of the 47 enrolled MM patients, 46 (male 27; female 19) were eligible for BD induction treatment, while the remaining one achieved CR before BD induction. The median age of the patients was 59 (range: 35-67) years. Of the 44 patients whose karyotype analyses were available, normal karyotype was observed in 35. Abnormal karyotype included complex type in 4, diploid in 1, and other abnormalities in 4. FISH revealed deletion of p53 in 5 of 39 patients whose information was available; deletion of 13-chromosome in 16 of 42, IgH-MAF fusion in 1 of 40; IgH-FGFR3 fusion in 5 of 41; IgH-BCL1 fusion in 9 of 39. Of the 46 MM patients, 19 received HD-DX prior to BD induction, and 34 received ASCT after BD induction treatment (Figure 1). During the BD induction phase, 3 patients experienced disease progression, and BD treatment was discontinued in 9 patients because of their consent withdrawal (n=2) and adverse events (n=7) including interstitial pneumonia in 2, persistent neuropathy in 1, CMV enterocolitis in 1, heart failure in 1, diabetes mellitus in 1, and liver dysfunction in 1. After BD induction phase (n=46), their response was >= CR in 4 (8%), very good partial response (VGPR) in 10 (22%), partial response (PR) in 18 (39%), stable disease (SD) in 2 (4%), and progression or withdrawal in 12 (26%). After ASCT, their response was >=CR in 9 (20%), VGPR in 11 (24%), PR in 12 (26%), SD in 1 (2%), and additional progression or withdrawal in 1 (2%). Of the 24 patients who received ASCT and whose response was less than CR, 21 received BD consolidation therapy for a median of 4 courses (range: 1- 8). BD consolidation was discontinued in 4 patients due to persistent neuropathy or cytopenia. Finally, maximum response after ASCT with or without BD consolidation was >= CR in 19 (41%), VGPR in 7 (15%), PR in 6 (13%), < SD in 2 (2%, Figure 2). Through BD consolidation, CR was achieved in 8 of 11 patients with post-ASCT VGPR and 2 of 12 patients with post-ASCT PR. In total, 4-year progression-free survival (PFS) and overall survival (OS) was 43% (95%CI: 28-57%) and 80 % (95%CI: 64-90%), respectively. Focusing on CR patients after ASCT and those who actually received BD consolidation, PFS adjusted for karyotype and age were not different between CR patients after ASCT and after BD consolidation, while patients with VGPR or less after consolidation had significantly lower PFS (Figure 3). [Conclusion] BD induction and ASCT provided CR rate of 27% among ASCT patients, although BD induction may expectedly cause adverse events including persistent neuropathy and viral infections. Patients who achieved CR after ASCT showed good PFS, and targeting CR through BD consolidation might improve CR rate. It is worthwhile to prospectively compare the efficacy of BD consolidation only for patients who failed to achieve CR or universal consolidation strategy.

BTI-322, a rat monoclonal IgG2b directed against the CD2 antigen on T cells and natural killer (NK) cells, blocks primary and memory alloantigen proliferative responses in vitro. We have evaluated the pharmacokinetics and safety of BTI-322 during treatment of 20 transplant recipients with steroid-refractory acute graft-versus-host disease (GVHD). Treatment consisted of BTI-322 by intravenous (IV) bolus or 30-minute infusion at approximately 0.1 mg/kg/d for 10 days in addition to continuing high-dose steroids and tacrolimus or cyclosporine. Pharmacokinetic sampling was performed in 10 patients; the t1/2 ± SE was 9.1 ± 1.3 hours, the Cmaxwas 2,549 ± 291 ng/mL, the Vd was 3.97 ± 0.95 L, and the Vd/kg was 0.05 ± 0.01 L/kg. Ten patients experienced transient dyspnea sometimes accompanied by nausea, vomiting, diarrhea, and tachycardia shortly after the initial bolus dose of drug, but serious drug-related adverse events were not seen during the remainder of the infusions. At the end of treatment (day 11), there were six patients with complete responses and five with a reduction in grade of GVHD for a total response rate of 55% (95% confidence interval [CI], 32% to 77%). Antibodies targeting CD2 may be active in the treatment of acute GVHD, and evaluation of a humanized form of BTI-322 is warranted.
