Abstract Objectives Relapsed/refractory AML patients  have a poor prognosis; allogeneic hematopoietic stem cell transplantation (HSCT) is the only chance in this setting to achieve long-term disease-free survival (1). It was previously established the activity of clofarabine plus cytarabine in AML relapse (clofarabine dosed once daily for 5 days with 40 mg/m2  followed 4 hours later by ara-C at 1 g/m2 per day)(2).However, modifications of this combination in AML therapy of relapsed/refractory patients warrant further evaluation. Therefore, our goal was to determine the efficacy and safety of clofarabine at lower dosage followed by  cytarabine (Ara-C) in adult patients with relapsed or refractory acute myeloid leukemia (AML) and to evaluate the capacity of this regimen as a bridge for HSCT. Methods Patients aged 18-65 years with refractory/relapsed AML were treated at the dose of clofarabine 30 mg/mq on days 1-5 and cytarabine 1000 mg/mq gg on days 1-5. We evaluated the complete remission rate (CRR), duration of remission (DOR) and overall survival (OS). Minimal residual disease (MRD) by molecular targeting was considered in all patients. Results Twenty-five (25) patients aged 29-64 years (median 47), who were fit for allogenetic HCT,  received one cycle of 30 minutes infusion of  clofarabine 30 mg/mq, followed 4 hours later by 3 hours infusion of  intermediate dose cytarabine 1000 mg/mq  days 1-5. Only in the first three patients this schedule was followed by gentuzumab. Nine (36%) patients had refractory disease (seven after one induction regimen, one after two previous regimes, one after a prior hematopoietic stem cell transplant (HSCT);  16 (64%) patients  were in their first (12 patients) or second relapse (4 patients); among the 12 patients in first relapse, 5 were from an allogeneic stem cell transplant.  Fourteen patients (56%)  achieved a complete remission (CR), seven (28%) was refractory and 4 (16%) died of treatment related mortality. Eleven (44%) patients  underwent (9 in CR) to allogeneic transplants or DLI infusion (3 patients refractory, and 8 patients relapsed), only one  patient underwent to autologous transplant. One patient, who was relapsed after prior HSCT, obtained a CR but he developed acute  graft vs host disease after therapy  and died in molecular CR*.  Among all patients underwent HSCT after Clofa/Ara-c salvage, six patients (50%) are still alive and in complete remission, six patients (50%) died because of  HSCT complications or AML relapse. The complete remission rate (CRR) was  (56,00 %), the median  Overall Survival  was 5 months for all patients (range 1-38 M), 11 Months for those underwent to tranplantation and 1,5 Months for non transplanted group. Treatment was complicated by neutropenic fever (n=17), grade III-IV mucositis (n=2) , skin rush  (n=4) grade II- III, hepatic transaminase elevations (n=2).  Two (n=5) patient died before their disease status could be evaluated. Conclusions These preliminary results suggest that combination treatment with clofarabine 30 mg/mq and ARA-C 1000 mg/mq is effective in this particularly poor prognosis category of patients, resulting in an ORR very favorably,  representing a potential “bridge” toward bone marrow transplant procedures (among the 14 patients who achieved a CR, twelve (85%) proceeded to HSCT, and six are still alive). The safety profile is acceptable in this relapsed/refractory population, and our results are very similar to previous regimes using higher clofarabine dosages.  More studies with this combination in adults are warranted.

e18503 Background: There is no standard treatment for acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) relapsing after allogeneic stem cell transplant (SCT). Options include combination chemotherapy, withdrawal of immunosuppression, donor lymphocyte infusion (DLI), and second SCT. Previous studies have used fludarabine, cytarabine, and granulocyte colony stimulating factor (FLAG) or second SCT separately for salvage therapy. Our institution uses FLAG followed by SCT from the same donor (FLAG/SCT) in this setting. We report a retrospective study of FLAG/SCT in MDS and AML patients relapsed after SCT. Methods: Patients who received FLAG/SCT for treatment of relapsed AML or MDS between 2009 and 2018 were identified using the bone marrow transplant database at University of California Davis. Their baseline characteristics and outcomes were determined using the electronic medical record. Descriptive statistics and Kaplan-Meier survival analysis were used to describe patients, rates of graft-versus-host disease (GvHD) and estimate survival times. Results: Nineteen patients received FLAG/SCT for AML (n=18) and MDS (n=1). Median time to relapse from first SCT was 145 days (range 41 to 960 days). Prior to FLAG/SCT, 17 patients had medullary relapse (median bone marrow blasts 27%; range 7-85%). Two patients had extramedullary relapse. Eighteen (94.7%) patients achieved complete remission (CR) after FLAG/SCT. Median follow-up time was 354 days from the first day of FLAG/SCT (range 7 to 2144 days). Six patients (31.6%) relapsed with median time to relapse of 334 days (range 78 to 679 days) after treatment. Overall survival at 2 years was 52.5%. Causes of death were relapsed AML (n=4; 21.1%), infection (n=4; 21.1%) complications of GvHD (n=3,15.8 %), and brain herniation (n=1, 5.3%). Acute GvHD grade I-IV and new onset chronic GvHD occurred in thirteen (68.4%) and eight patients (42.1%), respectively. Conclusions: FLAG/SCT for AML and MDS relapsing after SCT resulted in a high remission rate. The overall survival of over two years suggests that the second SCT augmented the graft versus leukemia effect. The GvHD rate increased after second SCT, but the rate and severity were manageable. FLAG/ SCT is a reasonable option for relapsed AML and MDS after SCT.
