Abstract The development of nonmyeloablative conditionings has recently reduced the transplant-related mortality (TRM) and extended the eligible age for transplantation up to 65–70 years. From January 2000 to June 2005, 106 newly diagnosed patients younger than 65 years were enrolled in a prospective phase II study at 15 Italian Centers. Fifty-eight were also previously described in a comparison of autografting with allografting based on a genetic randomisation (Bruno et al. N Engl J Med 2007). Here we report on a larger GITMO experience with a longer follow-up. Induction chemotherapy consisted of VAD-based regimens, followed by a cytoreductive autograft with melphalan 200 mg/m2, and by a non-myeloablative 2 Gy TBI-based allograft from an HLA-identical sibling. Graft-vs-host disease (GVHD) prophylaxis included cyclosporin and mycophenolate mofetil. Primary endpoints were overall (OS) and event-free (EFS) survivals. Secondary endpoint was TRM. One-hundred-two (96%) patients, median age 54 (30–65), completed the tandem program whereas 4 withdrew their consent. After a median follow-up of 54 (21–94) months, OS was not reached and median EFS was 35 (31–56) months post-transplant. Incidences of acute grade II-IV GHVD and extensive chronic GVHD were 40% and 50% respectively. Fourteen (13%) patients died from TRM, 14 (13%) from disease progression, 2 from lung cancer (2%) and 1 from lymphoma (1%). Overall response, defined as complete (CR) and partial remission, was 91% (93/102), with 53 patients achieving CR. Overall 39/102 patients relapsed, however only 8/53 of those who reached CR post-transplant. By multivariate-analysis disease response prior to allografting was significantly associated with longer OS (HR 0.27, CI 0.09–0.80, p<0.018) and longer EFS (HR 0.23, CI 0.11–0.49, p<0.001). Interestingly, chronic GVHD was not correlated with either the achievement of post-transplant CR (HR 0.87, CI 0.45–1.65, p<0.66) or its duration (HR 0.79, CI 0.45–1.40, p<0.42). Presence of del(13) was evaluated only in a subset of 39 patients: 13 carried del(13) and 26 did not. OS was not reached in the patients without del(13) and was 52 months in patients with del(13) (p=0.32), however EFS was not reached in the patients without del(13) whereas was 27 months for patients with del(13) (p=0.04). Given the encouraging results, the design of prospective studies that incorporate new drugs to cytoreduce the disease pre-transplant and enhance graft-vs.-myeloma are warranted to lower relapse rates and improve clinical outcomes.

Abstract Abstract 1151 Poster Board I-173 Introduction The mainstay of treatment for chronic graft-versus-host disease (GVHD) is steroid. However, there is limited treatment option for steroid-refractory chronic GVHD. Although the pathogenesis of chronic GVHD is still uncertain, the possible relation of auto-antibodies with chronic GVHD (Patriarca F, et al. Exp Hematol 389-96, 2006) and the result from a previous pilot study (Cutler C, et al. Blood 756-762, 2006) suggested that a treatment strategy targeting against B cells might become another effective therapy for chronic GVHD. Thus, we performed a study to determine the efficacy of rituximab (Mabthera®, Roche), an anti-CD20 monoclonal chimeric antibody in patients with steroid-refractory chronic GVHD. Patients and methods This is a multicenter, open-labeled prospective phase II study performed by the Korean Society of Blood and Marrow Transplantation (NCT00472225). Patients should be diagnosed as chronic GVHD according to the criteria for clinical trials in chronic GVHD proposed by National Institutes of Health Consensus Development Project (Filipovich AH, et al. Biol Blood Marrow Transplant 945-56, 2005). The steroid-refractoriness was defined as the same severity during the last one month while patients received the equivalent of prednisone ≥0.5mg/kg per day or 1mg/kg every other day at least for 30 days or longer. The treatment schedule consists of induction (rituximab 375mg/m2 weekly IV for 4 consecutive weeks) and maintenance (rituximab 375mg/m2 monthly IV for 4 consecutive months). The response and the quality of life (SF36 questionnaire) were evaluated during the follow-up. Results 37 patients (20 male, 17 female) were evaluated, and their median age was 29 years (range 8-57 years, 7 patients from pediatrics and 30 from internal medicine). The time interval between transplantation and rituximab treatment was from 4.0 to 45.7 months. The most commonly involved organs were skin, oral cavity, eyes and lungs. The average number of involved organ per each patient was three and their average severity was grade 2-3. The median potential follow-up was 12.3 months (95% confidence interval: 12.06-12.54 months). The maximum response during follow-up was as follows: 8 complete response (21.6%), 22 partial response (59.5%), 6 no response (16.2%), and 1 disease progression (2.7%). Thus, the overall response rate was 81.1%. The dosage of steroid was reduced in all responders including complete withdrawal of steroid. The quality of life was improved in terms of physical health and mental/emotional health after treatment. However, 5 responders showed the progression of disease activity during follow-up, and infectious complications were life-threatening, thus, 8 patients died due to infections including pneumonia. The involvement of skin and oral cavity showed better response than the involvement of lungs and eyes. Conclusion The weekly administration of rituximab followed by monthly maintenance rituximab may be an effective treatment for steroid-refractory chronic GVHD, however, the active prophylaxis against infection should be considered.

4124 Background: This study reports the final analysis (n=50) of a prospective phase II study evaluating the efficacy of the combination of sorafenib and doxorubicin eluting bead transarterial chemoembolization (DEB-TACE) in patients with unresectable hepatocellular carcinoma (HCC). Methods: Protocol consisted of 6-week cycles with sorafenib at 800 mg/day beginning 1 week prior to DEB-TACE; up to 4 DEB-TACE treatments within 6 months. Tumor response was assessed by RECIST and EASL criteria using MRI at baseline and at 1 month follow-up. Time to untreatable progression (TTUP) was defined as the interval from initiation of sorafenib therapy until inability of patient to further receive intra-arterial therapy. Overall survival (OS) and TTUP were calculated with the Kaplan-Meier method; outcomes were stratified by BCLC A/B and C and compared with the log-rank test. Results: DEB-TACE + sorafenib successfully performed in 50 patients: mean 62yrs (range, 31-88 yrs), Child-Pugh A/B (92%/8%), BCLC A/B/C (10%/28%/62%), ECOG 0/1 (52%/48%), HCV/HBV (44%/8%), mean tumor burden 20%, mean tumor size 7.2cm (range, 1–17.6), and mean tumor enhancement 78%. Patients were enrolled for a median of 3 (range, 1-22) cycles including a median of 1 (range, 0-6) DEB-TACE procedure. Median dose regimen was 400mgQD and the median dose taken while on study was 318 mg/day (range, 100-800). 1 month follow-up showed a mean tumor enhancement reduction of 48.2% (n=46, p<0.001) and an average reduction in lesion diameter of 8.5%(n=48, p=0.02). The Disease Control Rate was 98% using the EASL amendment and RECIST. Median TTUP was 11.9 mths (95% CI, 1.8-22 mths) with a significant difference between BCLC A/B (median 22.9 mths) and BCLC C (median 6.2mths) patients (log-rank, p=0.01). Median OS was 24.5 mths (95% CI, 14.3-35 mths) with a significant difference between BCLC C (median 17.1 mths) and BCLC A/B (median 33.7 mths) patients (log-rank, p=0.001). Conclusions: The results of this phase II study suggest a potential benefit to the combination of sorafenib and DEB-TACE. Single arm and non-randomization are limitations of the study. Clinical trial information: NCT00844883.

8536 Background: We report the outcome of patients included in the LNH 03-7B prospective phase II study of the GELA group which evaluated the tolerance and efficacy of a reduced dosage chemotherapy regimen (miniCHOP) associated with full dose rituximab in patients aged over 80 years with DLBCL. Methods: Patients were between 80 and 95 years (median 83 years), had disease stage I Bulky to IV and 65% had poor risk lymphoma according to IPI. Perfomance status was 0-2 in all cases. The majority of deaths and grade III/IV toxicity occurred during cycle 1 and 2. Response to treatment and early survival analyses were previously presented with 20 months median follow-up (Lancet oncol 2011;12:460-468). Results: At the time of this analysis, The median follow-up time was 41 months and 75 (50%) patients were alive. The 4-year estimated overall survival (OS) was 49.3% [95% CI: 40.8-57.3%] and the median OS was 38 months. The 4-year estimated PFS, EFS and DFS were 41.4% [95% CI: 33.1-49.5%], 39.4% [95% CI : 31.2-47.5%] and 57.9% [95% CI : 47.3-67.2%] respectively.]. During the additional follow-up, 8 patients relapsed (10% of CR patients) and 17 died. No long term toxicity was recorded. In a multivariate analysis an albumin level >35 g/l remained significantly associated with a longer survival. Conclusions: These results show that very old patients with DLBCL treated with RminiCHOP could express long-term survival and probably be cured. Regarding the DFS and despite the early toxicity, it seems crucial to obtain the best possible response. This long term analysis confirm that in patient aged over 80y with DLBCL and with PS from 0 to 2, RminiCHOP is the treatment cornerstone. Clinical trial information: NCT01087424.

TPS7565 Background: AML, the most common acute leukemia in adults, is a heterogeneous malignancy characterized by uncontrolled clonal expansion of hematopoietic progenitor cells. Median diagnosis age is ~67 yrs. Despite current therapies prognosis is poor with 5-yr OS ~25% for patients (pts) ≥65 yrs. For pts unable to receive intensive chemotherapy, survival rates are worse, indicating a critical need to develop better treatments. CD70 is expressed on >95% of AML blasts harvested from newly diagnosed AML pts but not on normal hematopoietic stem cells nor most normal tissues. Cusatuzumab is a first-in-class, high-affinity anti-CD70 monoclonal antibody with multiple mechanisms of action, including Fc-mediated cytotoxicity with enhanced ADCC and inhibition of CD70/CD27 signaling, resulting in leukemia blast and stem cell cytotoxicity. As cusatuzumab and azacitidine target distinct pathways of myeloblast propagation, a combination may have a synergistic therapeutic effect and overcome treatment resistance. Initial data from a Phase I study (NCT03030612) with cusatuzumab (1–20 mg/kg) + standard dose azacitidine in AML pts ineligible for intensive chemotherapy showed no dose-limiting toxicity and a CR/CRi (CR with partial/incomplete hematologic recovery) in 10 of 12 pts (ASH 2019, Abs #234). This abstract describes a follow-on Phase II study (NCT04023526). Methods: CULMINATE is a 2-part study of cusatuzumab + azacitidine to determine the optimal dose of cusatuzumab (Table). Inclusion criteria: ≥18 yrs with de novo or secondary AML unfit for intensive therapy (≥75 or <75 yrs with a comorbidity [i.e. ≥1 of: ECOG 2, severe cardiac/pulmonary or moderate hepatic impairment]). In Part 1, pts are randomized 1:1 to cusatuzumab 10 or 20 mg/kg (IV, on Days 3 and 17 of each 28-day cycle) + azacitidine (75 mg/m2 SC or IV on Days 1–7). Data will be reviewed after 15, 30 and 50 pts are enrolled into each arm to select the cusatuzumab dose for the Part 2 expansion cohort in which efficacy and safety will be further evaluated. Follow-up continues until death, loss to follow-up or study end. The primary objective is to determine CR rate. Secondary objectives include rate of CRi/CRh, rate of MRD-negativity, ORR, time to and duration of response, pharmacokinetics, immunogenicity, transfusion independence and safety. Enrollment began in Sept 2019 and is currently two-thirds complete. Clinical trial information: NCT04023526 . [Table: see text]

7007 Background: Myeloablative stem cell transplants have a lower rate of relapse than reduced intensity regimens. Timed sequential busulfan (TSB) with fludarabine (Flu) is a promising myeloablative regimen for patients undergoing matched sibling (MSD) or unrelated (MUD) donor transplantation (HCT) with low non-relapse mortality (NRM) (Popat et al Lancet Haematology 2018), but was not tested in haploidentical (haplo). Also, whether this approach can be used with post-transplant cyclophosphamide (PTCy) in MSD, MUD and haplo HCT is unknown. To address these issues, we conducted a prospective phase II study. Methods: Patients with hematological malignancies with MSD, MUD or haplo donor were eligible. They received fixed doses of Busulfan(BU) 80mg/m2 either on day -13 and -12 (n=45) or on -20 and -13 (n=10). Then, Flu 40mg/m2 was given on day -6 to -2 followed by Bu dosed to achieve target area under the curve (AUC) of 20,000 umol/min for the whole course based on pharmacokinetic studies. Thiotepa 5mg/kg was given on day -7 to haplo group. GVHD prophylaxis was PTCy 50mg/kg on day 3 and 4 and tacrolimus. Haplo and later MUD recipients also received mycophenolate mofetil. Results: 55 patients with a median age of 47 (15-65) years were enrolled. 30 patients had AML or MDS, 9 CML or MPD, 5 lymphoma, 5 myeloma and 6 ALL. About half had haplo 26 (47%); others had MUD 18 (33%) or MSD 11(20%). Disease risk index was high in 18 (32%), intermediate in 32 (58%), and low in 5 (9%) patients. Comorbidity score was ≥3 in 22 (40%) patients. With a median follow up of 17 months (5-28), 1-year OS, PFS, NRM and relapse rates were 71% (60-84%), 63% (51-77%), 20% (9-31%), and 17% (7-27%), respectively [Table]. There were no graft failures. Day 100 grade II-IV and III-IV acute GVHD rates were 38% (25-51%) and 9% (95% CI 1-17%), respectively; 1-year chronic GVHD and extensive chronic GVHD rates were 10% (2-28%) and 8% (0-15%), respectively. 1-year OS in MSD, MUD and haplo groups were 91% (75-100%), 72% (54-96%), and 62% (45-83%) respectively (P=0.11). Conclusions: Myeloablative TSB with PTCy is feasible in MSD, MUD and haplo HCT. It lowers the incidence of severe acute and chronic GVHD without apparent increase in relapse. Clinical trial information: NCT02861417. [Table: see text]

The Impact

Abstract Systemic PTCL, with the exception of alk-positive anaplastic large cell lymphoma (ALCL), have a poor prognosis. ASCT has been shown to have a favourable impact on relapsed PTCL. Therefore, the NLG designed a prospective multicenter phase II study to evaluate the impact of a dose-intensified induction schedule (6 courses of two-weekly CHOEP) consolidated in 1st PR/CR with high-dose therapy (BEAM) followed by ASCT in previously untreated systemic PTCL. This is the largest prospective PTCL-specific trial published so far. Newly diagnosed non-primary cutaneous PTCL cases aged 18–67 yrs were eligible for enrollment. Cases of alk-positive ALCL were excluded. From Oct 2001 to Feb 2006, 99 histologically confirmed PTCL cases were included in the study: PTCL unspecified (n=41), alk-neg ALCL (n=24), AILT (n=15), enteropathy-type (n=12), panniculitis-like (n=3), T/NK nasal-type (n=2), hepatosplenic (n=2). The M/F ratio was 1.8 and the median age 55 yrs (range 20–67 yrs). Although almost 2/3 of the cases presented with advanced-stage disease (62%), B-symptoms (61%) and/or elevated s-LDH (63%), the majority of them (65%) had a good performance score (WHO 0–1) at diagnosis. Of the 77 patients, where information was available for all 6 induction courses, 68 (88%) were in CR (31) or PR (37) after the 3rd and 66 (86%) after the 6th course. A total of 58 patients (75%) went through ASCT indicating that at least a fourth of this younger patient cohort has a primary refractory disease and fails therapy before reaching the transplant. Treatment-related toxicity after both induction and high-dose treatment was manageable. Of the 58 transplanted patients, 50 (86%) were still in remission at re-evaluation short after transplant. In 39 patients follow-up data one year post-transplant were available: 30 are still in CR and 9 have relapsed, suggesting that post-transplant relapses probably account for another 25% of the original patient cohort. In conclusion, the present data indicate that a time- and dose-intensified schedule is feasible and effective in previously untreated systemic PTCL. Continuous remissions are not uncommon, but a longer follow-up is needed to further characterize long-term remission rates and evaluate their impact on time-to-treatment failure and overall survival.

Abstract Introduction: Bendamustine, a bifunctional alkylating agent, exerts a mechanism of action different from that of other conventional alkylators despite it remains mostly unknown. In patients with newly diagnosed or relapsed-refractory MM bendamustine has proven to be active either as monotherapy or in combination with new drugs, particularly bortezomib and immunomodulatory agents. Methods: The preliminary results of this prospective, phase II study conducted in 22 Italian centres are recently published (Blood Cancer J. 2013, 3: e162). Here we present the conclusive results of the combination Bendamustine (70 mg/m2 days 1, 8), Bortezomib (1.3 mg/ m2 days 1, 4, 8, 11) and Dexamethasone (20 mg days 1-2, 4-5, 8-9, 11-12) (BVD) administered every 4 weeks in patients with relapsed-refractory MM of any age, with adequate cardiac, liver and hematological function, not refractory to bortezomib and treated with no more than four previous lines of therapy. The primary endpoint of this study was achievement of a response at least PR, as to IMWG criteria, after four cycles of BVD. Patients achieving a response less than a PR were taken off-study. Patients obtaining at least a PR received two additional treatment cycles followed by a 12-months consolidation phase with cycles repeated every 2 months. Therefore, patients with a PR after the induction phase could receive up to 18 months of treatment and up to 12 cycles of BVD. Results: 75 patients were included in the study. Median age was 68 years (range 41-85 years), 26.5% had ISS stage 3, 19% IgA myeloma and 9% renal failure. Eight of 36 evaluable patients (22%) had high-risk cytogenetics. Patients had received a median of one prior line of therapy (range 1-4). All patients had received prior treatment with new drugs, such as thalidomide (57%), lenalidomide (54.5%), bortezomib (46.5%) or both (20%). Twenty-four patients (32%) were refractory to IMIDs. Best response rate was 75%, including 14 CRs (20%), 22 VGPRs (24%) and 27 PRs (31%). Five patients (6.5%) died early. Only prior treatment with bortezomib significantly reduced the response rate ≥ PR (48.5% vs 80%; P = 0.004). At a median follow-up of 27 months (range 18-38), 45 patients had progressed and 43 had died. Median TTP and PFS were 17 and 12.5 months, respectively while median OS was 24 months (40% at 3 years). After longer follow-up, prior therapy with bortezomib plus lenalidomide was confirmed as the only factor that significantly reduced TTP (9 vs 19 months; HR = 2.7; 95% CI = 1.3-5.8; P = 0.009), PFS (9 vs 15 months; HR = 2.1; 95% CI = 1.2-3.8; P = 0.020) and OS (17 vs 32 months; HR = 2.1; 95% CI = 1.2-3.9; P = 0.043). Grade 3-4 adverse events occurred in 55% of patients leading to therapy reduction in 24% and to protocol discontinuation in 11% of patients. The most frequent severe adverse events were thrombocytopenia (28%), neutropenia (20%), infections (12%), peripheral neuropathy (9%), gastrointestinal (5%) and cardiovascular events (4%). Compared with younger, patients aged > 70 years had a significantly higher incidence of grade 3-4 side effects particularly thrombocytopenia and infections with, consequently, a higher rate of therapy reduction and discontinuation. Moreover, 4/5 early deaths occurred in patients aged more than 70 years. Conclusions: BVD combination is an effective and well tolerated regimen in relapsed-refractory MM. Data suggest that the optimal target of BVD maybe patients younger than 70 years who has not previously received both bortezomib and lenalidomide.
