Abstract Abstract 2740 Background: Historically, treatment options for the approximately 30% of patients with Hodgkin lymphoma (HL) who have primary refractory disease or relapse after experiencing initial response have been limited to high-dose chemotherapy with autologous hematopoietic stem cell transplant (AHSCT). Development of novel therapeutic options is needed to improve outcomes in patients whose disease is refractory to or relapses after initial chemotherapy or subsequent high-dose chemotherapy with AHSCT. The oral mammalian target of rapamycin inhibitor everolimus showed promising efficacy and acceptable toxicity in 19 patients with heavily pretreated HL enrolled in a phase 2 study of everolimus monotherapy for relapsed, rare lymphomas (Johnston et al. Am J Hematol 2010;85:320-4). To confirm the efficacy and safety of everolimus monotherapy in patients with relapsed/refractory classical HL, we conducted a multicenter, open-label, 2-step, phase 2 study. Methods: Adults with classical HL that progressed after high-dose chemotherapy with AHSCT or a gemcitabine-, vinorelbine-, or vinblastine-containing regimen received everolimus 10 mg/day until disease progression or unacceptable toxicity. Response was assessed every 12 weeks via computed tomography with contrast or integrated positron emission tomography/computed tomography with contrast. The primary study endpoint was the overall response rate (ORR) evaluated according to the modified response criteria for malignant lymphoma (Cheson et al. J Clin Oncol 2007;25:579-86). Secondary endpoints included the disease control rate (DCR), duration of overall response, duration of disease control, progression-free survival (PFS), and safety. Results: A total of 57 patients were enrolled in this study; 57.9% were women, the median age was 32.0 years, 57.9% were pretreated with AHSCT, and 100% were pretreated with gemcitabine, vinorelbine, or vinblastine. Overall, 66.7% of patients experienced disease progression during previous therapies or discontinued previous treatment due to progression. At the time of analysis, 48 patients discontinued study treatment, most commonly due to disease progression (n = 25). The ORR and DCR were 42.1% and 77.2%, respectively (Table). The median time to response was 57 days. Median PFS was 9.0 months. Adverse events experienced by >25% of patients were fatigue (56.1%), thrombocytopenia (47.4%), cough (38.6%), rash (38.6%), pyrexia (31.6%), anemia (29.8%), dyspnea (28.1%), back pain (26.3%), and diarrhea (26.3%). Grade 3/4 adverse events were observed in 33 patients (57.9%); the most common were thrombocytopenia (21.1%) and anemia (12.3%). Stomatitis was experienced by 14 patients (24.6%) and was of grade 3 severity in 2 patients (3.5%). Pneumonitis was observed in 6 patients (10.5%) and was of grade 1 severity in 2 patients (3.5%) and grade 2 severity in 4 patients (7.0%). Conclusions: In this phase 2 study, everolimus monotherapy demonstrated favorable efficacy and a short time to response in patients with heavily pretreated, relapsed/refractory classical HL. The overall safety profile was consistent with that previously observed for everolimus in patients with HL and other cancers. The results of this study confirm previous results and support the further evaluation of everolimus in patients with classical HL. Disclosures: Johnston: Novartis: Consultancy.

Abstract Introduction: Treatment of relapsed or refractory DLBCL can be challenging and little progress has been made in recent years. Blinatumomab, a bispecific T-cell engager (BiTE®) antibody construct, engages CD3+ cytotoxic T cells, resulting in T-cell expansion and lysis of CD19+ B cells. In a prior phase 1 study, blinatumomab treatment resulted in an overall response rate (ORR) of 55% in a subset of patients with diffuse large B-cell lymphoma (DLBCL). In the present phase 2 study, we compared stepwise versus flat dosing of blinatumomab, and evaluated its efficacy in patients with relapsed/refractory (r/r) DLBCL. Methods: Eligible patients were ≥18 years of age, had an Eastern Cooperative Oncology Group performance status ≤2 and had DLBCL; patients were refractory to treatment, had relapsed following autologous HSCT, or had relapsed and were ineligible for autologous hematopoietic stem cell transplantation (HSCT). Blinatumomab was administered over 8 weeks by continuous intravenous infusion. In stage 1, stepwise dosing (cohort I: 9, 28, and 112 μg/day after weeks 1, 2, respectively) was compared to constant dosing of 112 μg/day (cohort II). Based on the benefit/risk assessment from stage 1, stepwise dosing (9, 28, and 112 μg/day) was chosen for cohort III in stage 2. Patients achieving response after 8 weeks of treatment could receive a 4-week consolidation cycle after a 4-week treatment-free period. All patients received prophylactic dexamethasone (2 × 20 mg before infusion start and at infusion start; 3 × 8 mg/day for the first 2 days after infusion start and at dose step). The primary endpoint was ORR by Cheson revised response criteria for malignant lymphomas. Response was evaluated by independent radiologic assessment. Results: As of the primary analysis, 25 patients have been enrolled and treated: 9, 2, and 14 in cohorts I, II, and III, respectively. Fifty-six percent of patients were men, and the median age was 66 years (range, 34–85). Seven (28%) patients had received prior autologous HSCT. Blinatumomab was received as a fourth-line systemic therapy following a median (range) of 3 (1-7) prior treatments. Median (interquartile range) duration of exposure for stepwise dosing (cohorts I and III) was 46.8 (22.1−76.9) days. Twenty-one patients were evaluable for response (cohort I, n=7; cohort II, n=1; cohort III, n=13). Four patients were not evaluable for ORR per protocol definition due to early treatment discontinuation (<1 week on target dose in absence of disease progression): 1 discontinued due to investigator’s decision and 3 discontinued due to AEs. Fourteen patients have died (cohort I, n=5; cohort II, n= 1; cohort II, n=8). Eleven deaths were due to disease progression, one patient died of cardiogenic shock and one from organ failure following transplantation; no cause of death was reported for one patient. Among the evaluable 21 patients, 9 patients responded (4 CRs, 5 PRs) resulting in an ORR of 43%. All patients who responded did so within the first 8-week cycle. Among responders (n=9), median duration of response was 11.6 months. All patients experienced ≥1 adverse event (AE). Regardless of causality and grade, the most common AEs were tremor (52%), pyrexia (44%), diarrhea (24%), fatigue (24%), edema (24%), and pneumonia (24%). Twenty-four (96%) and 5 (20%) patients had grade 3 and 4 AEs, respectively. Serious AEs occurred in 23 (92%) patients, regardless of causality; the most common were pneumonia (24%), device-related infection (16%), and pyrexia (16%). Two patients had fatal on-study AEs (pneumonia and disease progression), assessed as unrelated to blinatumomab. Seven patients (cohort I, n=3; cohort II, n=2; cohort III, n=2) had grade 3 neurologic AEs (grade 3 AEs occurring in >1 patient were disorientation, encephalopathy, aphasia, and epilepsy [n=2 each]). There were no grade 4 or 5 neurologic events. Conclusions: In this phase 2 study, a stepwise dosing regimen (9, 28, and 112 μg/day) was established as the preferred dosing for blinatumomab in DLBCL. Treatment with blinatumomab showed an acceptable safety profile and resulted in objective and durable responses in heavily pretreated patients with r/r DLBCL.

Abstract Introduction Blinatumomab, a bispecific T-cell engager (BiTE®) that redirects cytotoxic T cells to CD19+ B-lineage cells, has shown anticancer activity and acceptable toxicity in a phase 1 study in patients with relapsed/refractory non-Hodgkin lymphoma, including diffuse large B-cell lymphoma (DLBCL). Using a stepwise dose escalation treatment, the overall response rate (ORR) in patients with DLBCL was 55% (Goebeler et al. Hematol Oncol 2013;31[suppl 1]:197). This open-label phase 2 study has been initiated to investigate the efficacy and tolerability of blinatumomab in patients with relapsed/refractory DLBCL, comparing stepwise dose escalation with constant target dosing. Methods In this ongoing study, eligible patients must be ≥18 years of age, must have relapsed/refractory DLBCL and Eastern Cooperative Oncology Group performance status ≤2. Blinatumomab is administered by continuous intravenous infusion over 8 weeks. In part 1 of the study, two cohorts were evaluated using a double-step or flat dose escalation regimen, respectively, in order to achieve the target dose of 112 μg/d. Part 2 will investigate the selected treatment schedule from part 1. Data from part 1 (cohorts I and II) are presented herein. Patients in cohort I received stepwise blinatumomab dosing of 9, 28, and 112 μg/d during weeks 1, 2, and thereafter, respectively; patients in cohort II received blinatumomab at 112 μg/d throughout. After a 4-week treatment-free period, patients achieving an objective response were permitted to receive a 4-week consolidation cycle. All patients received prophylactic dexamethasone. The primary endpoint is ORR by Cheson (2007) revised response criteria for malignant lymphomas. Results To date, 11 patients have been enrolled and treated in part 1 of the study: nine in cohort I and two in cohort II. The median age was 73 years (range, 55–85); 64% of patients were women. Six (55%) patients had received ≥3 lines of previous systemic antitumor therapy; study treatment was given as fourth-line (median) systemic treatment. Three patients had received autologous hematopoietic stem cell transplantation. At the time of this analysis, seven patients were evaluable for response (cohort I, n=6; cohort II, n=1). The ORR based on independent radiological assessment was 57% (cohort I: complete response, n=1; partial response, n=2; cohort II: partial response, n=1). Three patients had progressive disease (all in cohort I). Four patients were not evaluable for ORR per protocol definition: early treatment discontinuation after <1 week on target dose in absence of disease progression, n=3; transformed DLBCL, patient only pre-treated for follicular lymphoma (patient achieved a CR), n=1. The most common adverse events (AEs) regardless of causality were tremor (64%), diarrhea (46%), and fatigue (46%). Ten of 11 patients had at least one grade ≥3 AE regardless of causality, with two patients (both in cohort II) experiencing grade 4 AEs (one patient with neutropenia and leucopenia; one with respiratory insufficiency). There were no grade 5 AEs. Ten of 11 patients had central nervous system (CNS) AEs, mostly tremor (64%), speech disorder (36%), and disorientation (27%). Five patients (cohort I, n=3; cohort II, n=2) had grade 3 CNS AEs (there were no grade 4 or 5 CNS events). The overall benefit/risk assessment revealed the dose administered in cohort I (stepwise dosing: 9, 28, 112 μg/d) to be the recommended dose for part 2 of the protocol. Conclusions In this ongoing phase 2 study, blinatumomab was tolerable and showed antitumor activity in adult, heavily pretreated patients with relapsed/refractory DLBCL. Part 1 of the study established a recommended blinatumomab dose for this patient population. The study continues to enroll patients in part 2 (cohort III).

Abstract The individual risk of infection and requirements for medical treatment after high-dose chemotherapy have been unpredictable. In this prospective, multicenter, open-label study we investigated the potential of granulocyte colony-stimulating factor (G-CSF) responsiveness as a predictor. A total of 168 patients with multiple myeloma or lymphoma received a single dose of subcutaneous G-CSF (lenograstim, 263 μg) after high-dose chemotherapy. Highly variable leukocyte peaks were measured and grouped as low (quartile 1; leukocytes 100-10 100/μL), medium (quartile 2; leukocytes > 10 100-18 300/μL), and high (quartiles 3/4; leukocytes > 18 300-44 800/μL). G-CSF responsiveness (low vs medium vs high) was inversely correlated with febrile neutropenia (77% vs 60% vs 48%; P = .0037); the rate of infection, including fever of unknown origin (91% vs 67% vs 54%; P < .0001); days with intravenous antibiotics (9 vs 6 vs 5; P < .0001); and antifungal therapy (P = .042). In multivariate analysis, G-CSF responsiveness remained the only factor significantly associated with infection (P = .016). In addition, G-CSF responsiveness was inversely correlated with grade 3/4 oral mucositis (67% vs 33% vs 23%; P < .0001). G-CSF responsiveness appears as a signature of the myeloid marrow reserve predicting defense against neutropenic infection after intensive chemotherapy. This study is registered at http://www.clinicaltrials.gov as NCT01085058.

Abstract Background Ruxolitinib is a potent JAK1/JAK2 inhibitor that has demonstrated rapid and durable reductions in splenomegaly, improved MF-related symptoms and quality of life (QoL), and prolonged survival in 2 phase 3 studies comparing ruxolitinib with placebo (COMFORT-I) and best available therapy (COMFORT-II). However, no clinical trial in pts with MF had been conducted in Asian countries, and only a limited number of Asian pts or healthy volunteers had been enrolled in any ruxolitinib study. Methods This study was an open-label phase 2 study evaluating ruxolitinib in Asian pts with PMF, PPV-MF, or PET-MF who had palpable splenomegaly ≥ 5 cm below the costal margin and intermediate-2– or high-risk MF by the International Working Group for Myelofibrosis Research and Treatment (IWG-MRT) criteria. Pts received starting doses of ruxolitinib 15 or 20 mg twice daily (bid) based on baseline platelet count (100-200 or > 200 × 109/L, respectively); dose adjustments balancing safety and efficacy were allowed to titrate each pt to their most appropriate dose. The primary endpoint was met if the proportion of pts achieving ≥ 35% reduction in spleen volume from baseline at week 24 was ≥ 27.5% as measured by MRI/CT. Symptomatic response was assessed as a secondary endpoint using the 7-day modified MF Symptom Assessment Form (MFSAF) v2.0 total symptom score (TSS) and European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30). The study was conducted in China (n = 63), Japan (n = 30), Korea (n = 17), and Taiwan (n = 10). The data cutoff date for this analysis was 7 June 2013. Results Overall, 120 pts were enrolled (PMF, n = 80; PPV-MF, n = 21; PET-MF, n = 19), and their baseline characteristics were as follows: median age, 61 years (range, 25-80 years); 51.7% female; 69.2% intermediate-2 and 30.8% high risk by IWG-MRT criteria; median palpable spleen size, 15 cm (range, 5-45 cm); median spleen volume, 2159 cm3; 55.8% of pts had prior exposure to hydroxyurea. The median follow-up was 8.44 months; 22.5% of pts discontinued treatment, primarily for adverse events (AEs; 9.2%) and disease progression (7.5%). The median duration of treatment was 8.44 months (range, 0.5-21.7 months), and the median daily dose was 20.64 mg/day in the 15 mg bid group (n = 46) and 36.11 mg/day in the 20 mg bid group (n = 74). All pts were evaluable for achievement of the primary endpoint, 101 pts remained on study and were evaluable at week 24, and 96 pts had nonzero scores on the MFSAF-TSS and were evaluable for a reduction from baseline. Most pts who had assessments at week 24 (91% [92/101]) had a reduction from baseline in spleen volume (Figure). The study met the primary endpoint, with 31.7% (38/120) of all pts achieving ≥ 35% reduction from baseline at week 24. Overall, 38.3% (46/120) of pts achieved ≥ 35% reduction from baseline in spleen volume at any time on study. As measured by the 7-day MFSAF, 49% (47/96) of pts achieved ≥ 50% reduction from baseline in TSS (median reduction, 47.2%). Pts experienced an improvement from baseline at week 24 in EORTC global health status/QoL (mean change, 5.2). The most common nonhematologic AEs (≥ 10%) regardless of relationship to study medication included diarrhea (25.8%), upper respiratory tract infection (17.5%), ALT level increased (15.0%), pyrexia (15.0%), AST level increased (13.3%), cough (11.7%), herpes zoster infection (11.7%), nasopharyngitis (10.8%), constipation (10.0%), gamma-glutamyl transferase level increased (10.0%), and headache (10.0%), and most were grade 1/2. Serious AEs were reported for 24.2% of pts, and 65.8% of all pts had grade 3/4 AEs. The most common new or worsening laboratory abnormalities were low hemoglobin (all grade 3, 55.7%), low lymphocyte (grade 3/4, 19.5%), low platelet (grade 3/4, 15.3%), and low ANC (grade 3/4, 7.6%) levels. AEs observed in this study were consistent with those observed in the 2 large phase 3 COMFORT studies. Six pts (5%) died on treatment or within 30 days of discontinuation. Summary/conclusions Findings from this study demonstrated that ruxolitinib was relatively well tolerated in Asian pts with MF and provided substantial reductions in splenomegaly and modest improvements in MF-associated symptoms. The AEs observed with ruxolitinib treatment in this study are consistent with those observed in the large phase 3 COMFORT studies, and there were no new AEs associated with ruxolitinib in Asian pts with MF.

Abstract Background: Treatment options for multiple myeloma (MM) refractory (ref) to immunomodulatory drugs (IMID) and proteasome inhibitors (PI) are urgently needed. Epigenetic agents e.g. the pan histone deacetylase inhibitor (HDACi) panobinostat (pan) to modulate the acetylation of histones and oncogenic proteins are promising. Preclinically in MM, pan is syngeristic when combined with dexamethasone (dex), lenalidomide (len), and bortezomib (btz) (Ocio EM et al. Haematologica 2010). The phase 3 PANORMA 1 study of 768 patients randomized to receive IV btz and dex with either pan or placebo revealed a 3.9 month increase in PFS and increased CR rates with pan but at the cost of an increase in grade 3/4 diarrhea from 8% to 25% (San Miguel, Lancet 2014). The safety/preliminary efficacy of pan-len-dex was assessed in a phase 1b study (Mateos et al, ASCO 2010) but was complicated by high dose dex toxicities. The maximum tolerated doses were used for this phase 2 study, however, we attenuated the schedule so that pan is given thrice weekly every other week (instead of weekly) and dex is given only weekly (table 1). Methods: Inclusion criteria were patients with rel or rel/ref MM (including IMID/PI ref), measurable disease, adequate organ function and hematologic parameters. Patients previously treated with a HDACi or currently receiving QTC prolonging medications were excluded. The primary objective in this open label, single arm phase 2 study was to evaluate the best overall response rate (ORR). Secondary objectives were to evaluate safety, duration of response (DOR), and overall and progression-free survival (PFS). Each drug was administered at the doses and schedule shown in Table 1. Results: 26 evaluable patients with progressive disease (PD) at screening have been enrolled with a median age of 64 (44% > 65 yo) and a median of 2 lines of therapy over 4 years since diagnosis. High-risk molecular findings were present in 14 patients (54%), including 4 with del p53 and 10 with gain of 1q21 by FISH (4 with concurrent t(4;14)). 22 (85%) were len- ref, & 35, 54, 23% were ref to each: pomalidomide (pom), btz, & carfilzomib. Responses include 2 complete responses (CR), 4 very good partial responses (VGPR), 4 PRs, 9 minimal responses (MR), and 3 stable diseases (SD), for an ORR of 38%, CBR (>MR) of 73%, and a median DOR of 6 mos. The median PFS was 6.5 mos. In the 22 len-ref pts, there were 4 VGPRs, 2 PRs, 8 MRs & 3 SDs, with a median PFS of 5.5 mos. Responses were even seen in 10 pom-ref pts including 1 VPGR, 1 PR, and 4 MRs. Grade 3/4 toxicities (regardless of drug attribution) were primarily hematologic, with neutropenia (40%), thrombocytopenia (23%) and anemia (4%) respectively. Grade 3/4 nonhematologic AEs included infections in 5 (1 while neutropenic), 3 diarrhea (transient), 4 fatigue & 1 pulmonary embolus and 1 pt each with: neck pain, QTc prolongation & weight loss. Patients requiring dose reductions of len/pan respectively were 4/4 for ANC, 5/1 for plts, 1/1 for febrile neutropenia & 5 len for fatigue, & 1 pan for asymptomatic T wave inversions. No doses were held or reduced for GI toxicities. Preliminary results from RNA-seq of bone marrow (BM) aspirates comparing > PR responders (R) vs < PR non responders (NR) identify 261 differentially expressed transcripts (p<0.05). Network analysis revealed "Antigen Presentation/Cell mediated immunity" as a top network function with TLR3 and MHC Class II complex as focus molecules. Immunophenotyping of the tumor microenvironment showed increased CD1c+ myeloid dendritic cells in Rs and conversely, increased CD123+ plasmacytoid dendritic cells in NRs (p<0.05). BM cytokine analysis revealed higher IL-6 and alpha-interferon levels at baseline in Rs. Interestingly, protein levels of Cereblon, Ikaros and Aiolos were not significantly different in the 2 groups. Conclusions: In rel/ref MM, the completely oral pan len dex demonstrates encouraging ORR, DOR, and PFS, even in len-ref patients with high-risk molecular findings, indicating the essential role of pan in attaining responses. In notable contrast to PANORMA 1, this regimen is well tolerated with no significant GI toxicities and primarily expected hematologic toxicities. Updated results of planned 27 pts, including correlatives, will be presented at the annual meeting. Table 1.

376 Background: Patients (pts) with germ cell tumors (GCT) who fail to be cured following multiple chemotherapy (CT) courses (± high-dose CT) have an extremely poor prognosis and long-term remissions are anecdotal. Pazopanib (PZP) is a potent and selective, orally available, TKI of VEGFR1, 2, and 3, PDGFRα, PDGFRβ, and cKit. Here we report the initial results of the ongoing open-label, single-group, phase II study which is sponsored by INT Milano (ClinicalTrials.gov NCT01743482). Methods: Pts with refractory GCT received pazopanib 800 mg/day orally until disease progression or evidence of unacceptable toxicity/side effects. Eligibility requirements included failure of at least two platinum-based CT, including high-dose CT. All pts underwent measurement of serum tumor markers (STM), a computed tomography and a FDG-PET after one month of treatment and q2 months thereafter. Results: From May 2013 to July 2013, five pts were enrolled, three in fourth, and two in fifth-line. Median age was 39 (IQR: 33 to 48). Three out of five had failed high-dose chemotherapy (HDCT), two had an extragonadal primary, all pts had at least one elevated STM at baseline, the sole parameter in one patient, two had liver metastases, four pts had a retroperitoneal relapse. Four had elevation of alfafetoprotein (AFP), one of human choriogonadotropin (HCG). Four were nonseminomas, one a pure seminoma. After the first month of treatment, four out of five pts had a decrease in marker levels, one patient had disease progression (PD). Two of the responding pts had a necrotic evolution of disease at computed tomography corresponding to a RECIST and metabolic (PET/CT) progression, two had a stable disease. Two-month follow up is available for three out of four responders: one interrupted PZP for toxicity and had a marker PD, another an increase to baseline levels and the last one a further reduction (pure seminoma, one out of five confirmed response at two months). There were two cases of hepatic toxicities (one G2 and one G3-4 with dose interruption). Conclusions: PZP is endowed with preliminary activity in extensively pretreated patients with GCT. The unique availability of STM in interpreting densitometric and metabolic response might provide insights into response assessment of solid tumors under antiangiogenic therapy. Clinical trial information: NCT01743482.

3604 Background: The link between taxane resistance and activation of PI3K/AKT/mTOR signaling suggests that by inhibiting this pathway in combination with anti-microtubule agents like paclitaxel may improve treatment outcomes in many malignancies. To investigate this further we combined the TORC 1/2 inhibitor sapanisertib (TAK-228), the PI3Kα isoform inhibitor serabelisib (TAK-117), and paclitaxel in a phase I trial to determine the safety, efficacy, and RP2D. Methods: Open label, cohort study using a traditional 3+3 dose escalation design with a maximum of 5 dosing cohorts. A dose expansion of cohort 4, the recommended RP2D, is planned for February 2020. Results: Enrollment to the DLT evaluation has been completed and the clinical results are summarized in Table. Sixteen patients have been enrolled; a majority were heavily pretreated and resistant to paclitaxel. Overall, the combination was safe and tolerable. One DLT occurred due to renal dysfunction in cohort 5. 360 adverse events have been reported, but only 28 (8%) grade 3 or 4 events. The most common events were leukopenia and non-febrile neutropenia. Two patients required dose reductions as a result of pneumonitis. The ORR is currently 46% in 13 evaluable patients. CBR is 69% and PFS is currently at 10 months. Two patients achieved a CR and three patients remain on treatment. Conclusions: The combination proved to be well tolerated in the doses and schedules used in cohorts 1-4 and exhibited very promising clinical activity in heavily pretreated patients. This regimen could prove to be a highly effective treatment option and a phase 2 study is warranted at the RP2D. Clinical trial information: NCT03154294 . [Table: see text]

Abstract Introduction: The use of high-dose post-transplant cyclophosphamide (PTCY) has revolutionized graft-versus-host disease (GVHD) prophylaxis and allowed to successfully reconsider haplotransplant in recent years. As this strategy significantly reduces the incidence of both acute and chronic GVHD, PTCY has been thereafter considered not only in matched settings but also as sole GVHD prophylaxis, at least when considering myeloablative allotransplant using matched sibling (MSD) or unrelated (MUD) donors and bone marrow as source of graft. Here, PTCY, as a sole GVHD prophylaxis, was tested in a reduced-intensity conditioning (RIC) setting, using peripheral blood stem cells (PBSC) as source of graft considering that this platform is currently broadly used worldwide in adults. Methods: This prospective monocentric phase 2 study was designed with the main objective to demonstrate the feasibility and safety of using only PTCY (without cyclosporine A nor mycophenolate mofetyl after transplant) in adults (18-70 years old) eligible for a RIC PBSC transplant with MSD or MUD. The Baltimore platform with 2 days of PTCY 50mg/kg/day on days 3 and 4 post infusion was considered as conditioning regimen, using fludarabine for lymphoid disease or clofarabine for myeloid disease. The primary objective was to appreciate the incidence of corticosteroid-resistant acute grade 3-4 GVHD (CR 3-4 GVHD) within 100 days post-transplant. According to statistical rules, patients have to be included in a step by step fashion (3, 3, 6, 15, 15 and 17 patients) for a total of 59 evaluable patients (meaning having received PTCY), in order to stop the protocol soon enough in case of excessive rate of deleterious severe acute GVHD (graded according to Mount Sinai International Consortium). Thus, the trial had to be stopped in case of documentation of &gt; 2 CR 3-4 GVHD for the first 3 patients, &gt;3 CR 3-4 GVHD for the first 6 patients, &gt; 4 CR 3-4 GVHD for the first 12 patients, &gt; 6 3-4 CR GVHD for the first 27 patients, &gt; 8 CR 3-4 GVHD for the first 42 patients and finally as soon as &gt; 9 CR 3-4 GVHD for the last included patients. All patients gave informed consent. The trial was registered at ClinicalTrials.gov Identifier: NCT03263767. Results: The results of the first 27 first patients (males n=17 and female n=10; median age: 59 years old (yo), range: 26-70) are reported here. They were included between February 2018 and November 2020. Diagnoses were AML (N=8), MDS (N=5), CMML (N=2), myelofibrosis (N=5), CML (N=1), DLBCL (N=1), T-cell lymphoma (N=1), Philadelphia positive B-ALL (N=1), CLL (N=1), lymphoblastic lymphoma (N=1) and mixed phenotype acute leukemia (N=1). Donors were MSD in 10 cases and MUD in 17. Only one primary graft failure was documented in a 61 yo MDS patient with active disease at transplant. He is however still alive in response after autologous reconstitution. With a median follow-up of 17.6 months (range: 10-42) for alive patients at the time of analysis (July 2021), 1-year and 2-year survivals were 80.9+7% and 74.7+9%, respectively, for both OS et DFS. GVHD-free/relapse-free survival (GRFS) at 1-year and 2-year was 58.7+9% and 52.2+10%, respectively. Three relapses (11%) and 6 deaths occurred. Deaths were due to acute GVHD in 4 patients (including 1 with sepsis and 1 with SARS-COVID 19 infection) and relapse in 2. Grade 2, 3 and 4 acute GVHD occurred in 11, 1 and 4 patients, respectively, for a total of 59% of grade 2-4 acute GVHD. CR 3-4 GVHD was observed in all of 5 patients with acute grade 3-4 GVHD and 4 died related to GVHD. Moderate/severe chronic GVHD occurred in 5/22 (22.7%) evaluable patients, including 4 still on immunosuppressive therapy at 40, 28, 25 and 16 months post-transplant. Overall non-relapse mortality (NRM) was 14.8% and related to acute GVHD. However, the number of cases conducting to stop the protocol was not reached. Conclusion: PTCY as a sole GVHD prophylaxis is here demonstrated as possible and relatively safe for adults receiving a matched PBSC Baltimore-based RIC allograft. The very good survivals reported here may be related to a strong GVL effect associated with the high incidence of acute GVHD. However, because of this high incidence and the fact that NRM was related to GVHD after this first analysis, we have now made an amendment to test the addition to PTCY of one day of anti-thymoglobulin (ATG) 2.5 mg/kg on day-2 for the next 32 patients to be included. This second cohort receiving PTCY+ATG as a sole prophylaxis is ongoing.
