Abstract Introduction Erlotinib is an epidermal growth factor receptor small-molecule inhibitor and is FDA approved for the treatment of lung and pancreatic cancers. In preclinical study, in vitro colony culture assays revealed that erlotinib at micro-molar concentrations effectively suppressed the growth and expansion of Polycythemia Vera (PV) hematopoietic progenitor cells while having little effect on normal cells. Several JAK inhibitors are being studied for the management of PV, one of which has been approved for the treatment of myelofibrosis (ruxolitinib). Aim To study the clinical effect of erlotinib in pts diagnosed with JAK2V617F + PV. Methods We conducted a single arm, prospective phase II study at the University of Oklahoma and the Oklahoma City VA hospitals in pts with WHO defined JAK-2 V617F positive PV from June 2010 to August 2012. Appropriate IRB approval was obtained in accordance with Hilsinki declaration. Pts had to be requiring phlebotomy. Toxicity was assessed by treating physicians using NCI version 4. Dose modification for erlotinib was done using label recommendations. Results Five Caucasian pts were enrolled (3 (60%) males, with median age at enrollment of 63 years, range 26-79). Pts had pretreatment median hemoglobin14.4 g/dL (10.4 -19.2 g/dL), median platelet count 511 x109 (424-681 x109), median white blood cell (WBC) 14.4 x109(7.8- 18.3 x109). Three pts had splenomegaly prior to treatment. Median number of prior pharmacologic treatments (hydroxyurea, anagralide or interferon) was 1, range 0-2. Pts were given erlotinib 150 mg orally daily for 16 weeks: responders (phlebotomy free or decrease in spleen size) were allowed to continue a total of 1 year of treatment, while non-responders were taken off the study. Three (60%) patients received therapy for 16 weeks and did not achieve hematological response or improvement in spleen size. Two (40%) pts were taken off the study after 2 doses secondary to severe toxicities (grade 3 colitis in 1 case, and grade 3 facial rash in 1case). No therapy continued beyond 16 weeks (due to toxicity or lack of response). All pts in the study developed rash (grade 1 – 3) and diarrhea (grade 1 – 2). Three pts developed mucositis (see Table 1). No death was observed during the study and follow up period (median follow up was 23 months, range 12-37 months). Study was closed due to lack of efficacy. Conclusions Despite in vitro efficacy of erlotinib as potent inhibitor of JAK-2 activity, erlotinib is not effective in pts with JAK-2 V617F positive PV with poor toxicity profile. Poor accrual was related to potential toxicity of erlotinib compared to alternative treatments in view of lack of clinical efficacy. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 1873 Background: CMML, now classified among MDS/MPN, is prognostically heterogeneous. We (JCO 1988 6:1417, Blood 1996 88:2480) and others found prognosis in CMML to depend on both “MDS factors” (% marrow blasts, cytopenias, karyotype) and “MPN” factors, ie splenomegaly (SMG), WBC count, extramedullary disease (EMD). Treatment of advanced CMML is difficult. The hypomethylating agents Azacitidine and Decitabine (DAC) have shown efficacy in CMML, but in prognostically heterogeneous cohorts. We conducted a phase II trial of DAC in a well defined cohort of advanced CMML. Methods: To be included, CMML (according to WHO) should have: if WBC<13G/l an IPSS≥1.5; if WBC≥13G/l, two of the following criteria: marrow blasts≥5%, Hb<10g/dl, plts<100G/l, abnormal cytogenetics, SMG >5cm below costal margin, (SMG>5cm), EMD, based on our previous prognostic factors. Pts received DAC 20mg/m2/d IV for 5 days every 28 days for at least 3 cycles. Response criteria were based on IWG 2006 for pts with WBC <13G/L and for pts with WBC > 13 G/L also included evolution of WBC, SMG and EMD (Blood 1996 88:2480). Results: Between Nov 2008 and June 2009, 41 pts were included in 16 centers, of whom 39 completed at least one cycle and were considered evaluable for response (the 2 other pts died from septic shock before and during the first cycle respectively). Median number of cycles was 9 (range 1–17). Median age was 71 years (range 54–88), M/F:30/9. Seventeen pts had CMML 1 and 22 had CMML 2 (including pts with up to 29% marrow blasts). Median WBC count was 29.5G/l (range 4.1–147.3), median blood monocytes 3G/l (range 1.05–95.7), and median BM blasts 10% (1-29). Nine pts had WBC<13G/l and 30 WBC≥13G/l. Abnormal karyotype was found in 18 (46.2%) pts, including +8 and -7 in 7 and 1 case, respectively. 15 pts (38.6%) had SMG>5cm and 8 (20.5%) EMD involving skin (n=5) and lymph nodes (n=3). Overall Response Rate (ORR,) was 38.6% with 4 (10.3%) CR, 8 (20.5%) marrow CR and 3 (7.7%) Stable Disease (SD) with HI. 1 CR pt received allo SCT. 18 (46%) pts had SD without HI and 6 (15.4%) pts progressed to AML. 8 (36.4%) of the 22 RBC transfused pts became RBC transfusion independent. 3/10 (30%) pts with plt<50G/l reached plt>100G/l. Four pts had cytogenetic response (3 CR and 1 PR) exclusively among pts with +8. Median peripheral monocyte count decreased from 4.8G/l to 0.3G/l after 3 cycles of DAC among responders. SMG disappeared in 6/15 (40%) pts and EMD in 6/8 (75%) pts. 16 pts were receiving Hydroxyurea (HY) at inclusion which could be stopped in 12 of them. With a median follow up of 10 months (1-18), 7 pts had died from progression (n=3), sepsis (n=3) and unrelated cause (n=1). Overall Survival (OS) estimate was 60% at 2 years (median not reached). By comparison, in our previous trial of HY in CMML where inclusion criteria were the same, 2 year survival was 43% (median OS 20 months; Blood 1996 88:2480), for a median follow up of 11 months (range1-43). The only factor associated with response to DAC was WHO subtype, CMML 2 pts showing significantly better ORR (30.8% vs 7.7% in CMML 1; p=0.041).There was no difference in survival between CMML 1 and 2 pts. Treatment with DAC was generally well tolerated with, except for usual grade 3/4 cytopenias, and grade 3 fatigue (n=1). Conclusion: DAC is active in advanced CMML and safe in these elderly pts. A possibly better survival than with HY will have to be confirmed in randomized trials. Correlative genetic studies identifying markers potentially predicting response and survival for DAC are currently underway in our lab. Disclosures: No relevant conflicts of interest to declare.

15509 Background: Our preclinical work has shown that epidermal growth factor receptor (EGFR) is expressed in ∼ 80% of undifferentiated NPC & gefitinib is a small molecule inhibitor against EGFR with anti-proliferative activity in NPC in vitro. Methods: We report the preliminary result of a phase II study of gefitinib in patients (pts) who progressed after 1–2 lines of chemotherapy (at least 1 line had to contain platinum) for metastatic or locoregionally recurrent NPC. Fourteen Chinese pts were accrued, of whom the median age was 48 years (range 34–64 years), 12 were males, 9 had metastatic & 5 had locoregionally recurrent NPC. All received gefitinib at 500mg/day orally, every 28 days with radiological assessment performed every 2 cycles for a maximum of 8 cycles. Ten pts had 1 line & 5 pts had 2 lines of prior chemotherapy. Results: The median number of administered cycles was 2 (range 1–8). Of the 14 pts evaluable for toxicity, the most commonly reported were acneiform rash (86%, grade 1–2, n = 10; grade 3, n = 4), dry skin (86%, grade 1–2), diarrhea (71%, grade 1–2), fatigue (64%, grade 1–2), anorexia (64%, grade 1–2) & nausea (20%, grade 2). Other grade 3–4 toxicities included fever (n = 2, skin cellulitis, infective pneumonia), hyponatremia (n = 2), near-syncope (n = 2), anemia (n = 1). Dose reduction to 250mg/day was required in 4 pts who encountered grade 3 skin rash. Of the 11 pts evaluable for response, 2 had stable disease (SD) for ≥ 6 months (m) (mean 6.8 m) 9 progressed and no partial responders. Five pts have died mostly of progressive disease & there were no treatment-related deaths. Conclusions: Gefitinib is well tolerated in pts with advanced NPC with some pts experiencing disease stabilization for over 6 months & study accrual is ongoing. No significant financial relationships to disclose.

Imatinib is a potent inhibitor of tyrosine kinases, including abl, c-kit, and platelet-derived growth factor receptor (PDGFR). A role for PDGF in PV has been suspected, and direct inhibition of PV colonies with imatinib has been reported. We initiated a phase II trial of imatinib in pts with PV diagnosed by the Polycythemia Vera Study Group criteria. Pts were treated with imatinib at 400 mg daily; if no significant response after 1 month (mo) of therapy, the dose could be escalated to 800 mg daily. Hydroxyurea could be used only during the first mo of therapy, but anagrelide was allowed at any time. 9 patients have been treated (6 male, 3 female). Median age was 51 years (yrs) (range 28 to 72 yrs); median duration of PV was 8 years (range 1/4–35 years). ECOG performance status was 0 for 2 pts and 1 for 7 pts. Most common symptoms included fatigue (n=7), intractable pruritus (n=5) and headache (n=4). 4 pts had splenomegaly, 1 had hepatomegaly, and 1 had prior splenectomy. All patients were dependent on repeated phlebotomies. All pts had diploid cytogenetics except one who had 20q− (prior therapy with 32 P). FISH and PCR confirmed absence of Bcr-Abl translocation. After a median follow-up of 4 mo (range, 2 to 37 mo), 3 pts have ≥50% reduction in phlebotomy requirements. These include one pt with complete remission defined as hemoglobin < 14 g/dl, no phlebotomies and complete resolution of splenomegaly. Pruritus improved significantly in 3 pts; fatigue improved in 3 pts, headache and visual symptoms improved in one pt each. The dose of imatinib was increased to 800 mg in 3 pts. Grade 3 diarrhea and liver dysfunction occurred in 1 pt requiring dose reduction to 300 mg daily. Grade 2 toxicities included edema (n=2), rash (n=1), bone pain (n=1) and diarrhea (n=1). We conclude that imatinib has activity in PV, leading to improved symptoms and decreased phlebotomy requirements.

Abstract Abstract 4789 Patients with WM commonly display low cholesterol levels, particularly LDL and VLDL levels. Given these observations, we examined their levels in 110 patients with WM, and observed decreased total cholesterol (<160 mg/dL), LDL (<100 mg/dL) and VLDL (<40 mg/dL) levels in 41 (37.3%), 68 (61.8%) and 90 (81.8%) patients, respectively. Importantly, median serum IgM levels which serve as a surrogate marker for WM disease burden were higher among patients with hypocholesterolemia (3440 vs. 1587 mg/dL; p=0.0004). Longitudinal follow-up of progressing as well as responding patients demonstrated an inverse correlation between serum IgM and cholesterol levels, which was not an artifact of laboratory testing. Importantly, significantly lower serum IgM levels (885 vs. 1960 mg/dL; p=0.004) were observed among those patients who were on a statin lipid-lowering agent. We therefore investigated the in vitro potential of statins to mediate anti-WM activity and showed that simvastatin acted a potent inducer of WM cell apoptosis through inhibition of geranylgeranylated proteins. Given these observations, we investigated the potential of simvastatin to suppress disease progression in WM patients with slowly progressing disease who would otherwise have been on watch and wait. Patients and Methods Eighteen patients, 8 of whom were previously untreated, and who were asymptomatic with slowly progressing disease were enrolled in this study. The median age for these patients was 67 (range 42-88 years), median IgM was 2,610 (571-5,880 mg/dL), and median hematocrit was 35.4 (range 30.2-41.4%). Patients received Simvastatin at 20 mg daily for the first week, then dose escalated weekly by 20 mg a day to a maximum of 80 mg daily by week 4. Patients were maintained on therapy until progression. Results With a median follow-up of 6 months (range 3-18 months), 7 patients have demonstrated objective disease progression. No objective responses have been observed in any treated patients. Among non-progressing patients, serum IgM levels (2,610 vs. 2545 mg/dL) and hematocrit (35.4% vs. 34.5%) remain stable (p=NS). Grade 2 toxicities included elevation in CPK (n=1), and musculoskeletal pain (n=3). No grade 3 toxicities were observed. Conclusions Simvastatin does not produce objective responses in patients with WM, though may have potential for suppression of disease progression in some patients with WM. Disclosures: No relevant conflicts of interest to declare.

e16184 Background: Hepatic derangement commonly accompanies advanced HCC (aHCC) and limits the use of systemic therapies. We aimed to evaluate the use of single agent anti-PD-1 nivolumab or pembrolizumab in Child-Pugh (CP) grade B or C patients with aHCC. Methods: Consecutive aHCC patients with CP grade B (CPB) or C (CPC) liver function who received single agent nivolumab or pembrolizumab were analysed. Objective response rate (ORR), time-to-progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were assessed. Results: Between May 2015 and June 2020, 61 patients were included. The median age was 60 (range 28-82). 81% and 4.8% had hepatitis-B and hepatitis-C related HCCs respectively. 72.1% (n = 44) were of CPB and 27.9% (n = 17) were of CPC. Amongst CPB patients, 19 (31.1% of all patients) had CP score 7 (CP7) and 25 (41.0% of all patients) had CP score 8 or 9. The median follow-up was 2.3 months. The ORR of CPB and CPC patients were 6.8% and 0% respectively (p = 0.553). The TTP of CPB and CPC patients were 2.1 months (95% C.I. 1.4-2.8) and 1.4 months (95% C.I. 0.6-2.1) respectively (p = 0.204). CPB patients had significantly better OS than CPC patients (3.1 months (95% C.I. 1.4-4.7), vs. 1.7 months (95% C.I. 1.0-2.4), p = 0.041). Compared to CP score ≥8 (CP≥8) patients, CP7 patients had significantly better OS (median OS CP7 6.7 months (95% C.I. 4.0-9.3), vs. CP≥8 1.8 months (1.2-2.4), p = 0.002). Patients with diuretic-refractory ascites had significantly worse OS compared to those without (1.7 months (95% C.I. 1.0-2.5) vs. 3.7 months (95% C.I. 0.1-7.3), p = 0.004). Portal vein (PV) thrombosis was also significantly associated with inferior survival, with median OS of patients with any PV thrombosis being 1.8 months (95% C.I. 1.0-2.5), compared to 5.3 months (95% C.I. 2.4-8.1) of those without (p = 0.004). The median number of doses given was 3 (range 1-34). Median treatment duration was 5.0 weeks (range 0-77). Overall, 25.4% of patients experienced TRAEs and 4.8% experienced grade ≥3 TRAEs. The most common TRAEs were skin-related (13.1%) and constitutional symptoms (6.6%). Conclusions: Nivolumab/pembrolizumab had acceptable safety in CPB/C patients with aHCC. CP7, absence of diuretic-refractory ascites and lack of PV thrombosis were associated with better survival.

11569 Background: Kaposi sarcoma (KS) is the leading cancer in Malawi (34% of cancers). Outside of clinical trials, prospective KS studies from sub-Saharan Africa (SSA) are few and limited by loss to follow up. We conducted a prospective KS cohort study of standard of care bleomycin/vincristine (BV) at Lighthouse HIV clinic, in Lilongwe, Malawi. Methods: We enrolled pathologically confirmed, newly diagnosed, HIV+ KS patients from Feb 2017 to Jun 2019. We collected clinical and treatment characteristics, toxicity, and outcomes of KS with follow-up censored Jun 2020. Patients were treated with bleomycin (25 mg/m2) and vincristine (0.4 mg/m2) every 14 days for a planned maximum of 16 cycles. STATA v13.0 was used to calculate descriptive statistics and Kaplan Meier survival analysis. Toxicity was graded using NCI CTCAE v5.0. Results: We enrolled 138 participants, median age 36 (IQR 32-44) and 110 (80%) male. By ACTG staging, 107 (78%) were T1 (tumour severity), 46 (33%) were S1 (illness severity) and 46 (33%) had Karnofsky performance status ≤70. Presenting symptoms included edema in 69 (53%), visceral disease in 9 (7%), and oral involvement in 43 (33%). Prior to KS diagnosis, 70 (51%) participants were aware of being HIV+ for median 17 months (IQR 6-60) and had been on ART for median 16 months (IQR 6-60). Median CD4 count was 197 (IQR 99-339), median HIV-viral load was 2.6 log copies/mL (IQR 1.6 – 4.8) and 57% were HIV-suppressed ( < 1000 HIV copies/ml). The median number of cycles was 16 (IQR 7-16). 62 (45%) participants missed at least one dose due to stock out. Amongst patients with missed doses, the median number was 3 (IQR 2-4) for bleomycin and 2 (IQR 1-3) for vincristine. 14 (10%) participants experienced at least one reduced dose due to toxicity. 5 (4%) participants suffered grade ≥3 anaemia, 13 (9%) grade ≥3 neutropenia, and one participant had grade 4 bleomycin-induced dermatitis. There was no reported grade ≥3 bleomycin lung toxicity or vincristine-induced neuropathy. Of 115 evaluable participants, responses at the end of therapy were: complete response in 52 (45%), partial response in 27 (23%) stable disease in 5 (4%), and progressive disease in 31 (28%). Median duration of follow-up was 20 months. At censoring, 69 (50%) were alive, 36 (26%) dead, and 33 (24%) lost to follow-up. Overall survival is shown Table as crude and worst-case scenario; worst-case assumes all participants lost to follow up died. Conclusions: Here, we present one of the most complete characterizations of KS presentation and treatment from SSA. As in other studies from the region, the majority of patients presented with advanced disease, chemotherapy stock-outs and loss to follow up were common, and mortality was high. Studies are planned to understand the virologic characteristics, improve therapies, and better implement existing therapies.[Table: see text]

Abstract BACKGROUND Pem, an immune checkpoint inhibitor, demonstrated to be activein various neoplasms with MMRd. No data exists about its efficacy in MMRdglioma patients. MATERIAL AND METHODS MMRd HGG relapsed after receiving RT and CT weretreated with Pem. MMR status was analyzed by immunohistochemistry,including the MLH1, MSH2, MSH6, and PMS2 markers. MMR deficiency wasdefined as presence of a weak (wMMRd) or absent (aMMRd) signal atimmunohistochemistry for at least one MMR protein. Other inclusion criteriawere: ECOG PS 0–2, histologically confirmed gliomas, dexamethasone ≤4 mg.Pem was administrated at 200 mg every 3 weeks until progression disease orunacceptable toxicity. Tumor response was evaluated by brain MRI every 10 weeksaccording to the RANO criteria. OS and PFS were evaluated by Kaplan-Meiercurves. CTCAE v4.0 was used for toxicity. RESULTS among 167 glioma patients, we found 22 MMRd gliomas. 12 PTS were treated with Pem: 8 wMMRd and 4 aMMRd. According to Bethesda criteria, allPTS had microsatellite stability. Tumor histologies included 5 anaplasticastrocytoma, 1 anaplastic oligodendroglioma, 6 glioblastoma (GBM). MSH2deficiency was found in 6 cases, MSH6 deficiency in 9 cases, PMS2 and MLH1deficiency in 2 cases. Median number of prior line of chemotherapy was 1 (range 1–5). Stable disease (SD) was reported in 4 PTS (33%); 8 PTS showedprogressive disease (PD). PTS with anaplastic gliomas showed a statisticallysignificant association with SD (p=0.03, OR=3); all GBM PTS reported PD; status of MMRd (weak/absent), IDH (mutated/wild-type), MSH2 and MLH6(deficient/proficient) were not associated with SD. Median follow up was 14.7 ms. OS was 5.6 ms (95% CI 0.1–13.8), PFS 2.4 ms (95% CI 1.8–2.9). OS was 2.8 ms and 5.6 ms (p=0.9), PFS was 1.8 ms and 3.1 ms (p=0.5) in PTS with wMMRd and aMMRd. PTS reporting SD and PD had PFS of 7.4 ms (95% CI 4.6–10.2) and 1.8 ms (95% CI 0.2–3.4), p=0.002; OS was “not reached” and 2.8 ms in PTS having SD vs PD (p=0.04). Grade ≥3 adverse eventswere reported in 8% of PTS. CONCLUSION a subgroup of recurrent MMRd HGG might benefit from Pem,especially anaplastic gliomas. There was a trend for a longer PFS and OS in PTS with aMMRd. Analyses for identifying additional molecular predictive factors is ongoing.

Abstract Since 1988 we have treated 66 patients with relapsed, refractory, or high-risk Hodgkin lymphoma (HD) with high-dose CEP consisting of cyclophosphamide 1,500 mg/m2/day × 4 (total dose, 6,000 mg/m2), etoposide 400 mg/m2 twice daily × 6 doses (total dose, 2,400 mg/m2), and cisplatin 50 mg/m2/day × 3 by continuous i.v. infusion (total dose 150 mg/m2) followed by infusion of autologous peripheral blood stem cells (n=49), bone marrow (n=16), or both (n=1). The patient population included 41 males and 25 females. The median age at transplant was 33 years (range, 17–64 years). Twenty-three patients (35%) had never achieved complete remission prior to transplant, 36 (55%) had previously achieved a complete remission but subsequently relapsed, and 3 (5%) were in first complete remission. Information regarding the disease status at transplant was unavailable for 4 patients (6%). Twenty-seven patients (41%) remain alive and free of any post-transplant relapse or progression as of the most recent follow-up, and an additional 10 patients (15%) manifested active disease post-transplant but are currently in remission following additional post-transplant therapy, yielding a total of 37 patients (56%) currently in CR. In addition, 5 patients (8%) remain alive with active disease, 23 patients (35%) died of progressive disease, and only 2 patients (3%) died of treatment-related causes including diffuse alveolar hemorrhage (1 patient) and hepatic veno-occlussive disease (1 patient). With a median follow-up of 4.4 years among surviving patients, the Kaplan-Meier 5-year estimates for event-free survival and overall survival are 34% and 60%, respectively, and five-year survival was superior among patients who had achieved at least one CR prior to transplant versus patients who had never been in CR prior to transplant (71% versus 43%, p = 0.03). Detailed adverse events data is available regarding all patients transplanted since September 1996: Of these, only 3 (7%) suffered grade 3 or greater pulmonary toxicity, 12 (29%) exhibited grade 3 or higher mucositis, and 10 (24%) had grade 3 or higher nausea or vomiting. The median number of days from transplant to neutrophil recovery (500 cells/uL) was 10 days, whereas the median number of days to platelet recovery (20,000 cells/uL) was 12 days. We conclude that high- dose CEP followed by autologous transplant is an active and well-tolerated treatment program in patients with relapsed or refractory HD. The low incidence of pulmonary toxicity is noteworthy given that a high percentage of patients had been exposed to bleomycin and/or thoracic XRT prior to transplant, and appears to be superior to that reported with conventional CBV-conditioned transplants in patients with HD.

Abstract Abstract 4560 Introduction The G-CSF, primary regulator of granulopoiesis, has shown its efficacy in reducing duration of neutropenia after chemotherapy or myelosuppressive therapy. In these situations G-CSF, accelerating the granulocytous reconstitution, may enable a significant reduction of the incidence, duration and severity of infection. Commercially formulations of rHu-G-CSF include lenograstim, a glycosylated form, and filgrastim, a non-glycosylated form. Glycosylation of the molecule contribute to pharmacokynetis advantages and to higher affinity to specific receptor. Additionally, lenograstim exposed neutrophils maintain unchanged all their functions in vitro, while filgrastim exposed neutrophils present functional defects due to higher adhesivity, cytoscheletric alterations and a more immature phenotype. Aim On these bases, we hypotized that lenograstim may prevent febrile episodes (FE) and reduce their lasting in patients with chemotherapy derived neutropenia more efficiently than filgrastim. Primary endpoint is the incidence of FE (ClinicalTrials.gov ID: NCT00932217). Patients and methods starting from April 2005, 180 multiple myeloma patients achieving high dose cyclophosphamide for stem cells mobilization were enrolled in 11 Italian Centers. Treatment plan consisted in: high dose cyclophosphamide (3 or 4 g/sqm) on day 1, G-CSF (random 1:1 on the base of a generated random list: filgrastim or lenograstim) 30 MU/day from day +4 to +9, 60 MU/day from day +10 to the achievement of an optimal CD34+ cell count for staminoapheresis. FE, significant if equal or higher than 38 °C for at least 2 different determinations, were recorded till day +30. Results 176 of 180 patients received scheduled treatment and are eligible for final analyses. All 176 patients underwent post-chemo grade 4 neutropenia and G-CSF was administered starting from day +4. FE were recorded in 26 pts, 16 in the filgrastim arm (89 total patients) and 10 in the lenograstim arm (87 total patients). The global fever incidence was 14.77%, 17.98% with filgrastim and 11.49% with lenograstim. However, to demonstrate functional block of filgrastim exposed neutrophils, FE have been related to neutrophil absolute count. Related to the neutropenia grade, 8 FE are recorded with filgrastim (8.99%) and 1 FE with lenograstim (1.15%) with absolute neutrophil count >500/μL (grade 3) (chi square test with Yates' correction: p=0.0436); this difference is still evident when neutrophils are >1000/μL (grade 2), with 7 episodes with filgrastim (7.87%) versus 1 (1.15%) with lenograstim. Conclusions Lenograstim is associated with a reduced global incidence of FE in multiple myeloma patients undergoing to high dose cyclophosphamide and stem cells mobilization when compared to filgrastim. Additionally, excluding the time frame when neutrophils are not yet recovered (neutrophils <500/μL; grade 4 neutropenia) and G-CSF effects may not be demonstrated, filgrastim treated patients present, when compared to lenograstim treated patients, an higher FE incidence at neutrophil absolute count recovery (both with grade 3 and grade 2 neutropenia), confirming the functional block of filgrastim exposed neutrophils described in vitro. On the contrary, lenograstim allows to recovery normally functional neutrophils as demonstrated by the very low incidence of FE (1.15% with neutrophils >500/μL) in treated patients.

Abstract Abstract 1973 Introduction: Outcome of patients with steroid refractory acute GVHD (aGVHD) remains poor and the optimal therapy remains ill-defined. ECP has been successfully used for treating steroid-resistant chronic GVHD. We studied the efficacy and outcome of ECP used as salvage therapy in patients with steroid refractory/dependent aGVHD at 2 centers: Vanderbilt University, USA and Nottingham, UK. Methods: Transplant and aGVHD characteristics of patients treated with ECP from 1/2006 to 8/2010 were reviewed. Steroid doses at onset and completion of ECP were available. Steroid refractory aGVHD was defined as progression after 3 days or no response after 7 days of systemic steroids. Steroid dependent aGVHD was defined as recurrence of aGVHD during steroid taper. Responses to ECP were abstracted from medical records and were determined at completion of ECP. Patients were transplanted for hematological malignancies on standard of care or IRB approved protocols. Results: Fifty two patients (Vanderbilt-29; Nottingham-23) were treated with ECP for steroid dependent (15, 29%) or steroid refractory (32, 63%) aGVHD at a median of 59 days (range, 12–99) after transplant. Indication for ECP was missing for 5 patients. aGVHD was seen after first transplant (44, 85%), second transplant (1, 2%) or after donor lymphocyte infusion (7, 13%), respectively. Grade 3–4 aGVHD was present at onset in 29 (57%) patients. Stage 3–4 skin, GI, and liver involvement occurred in 28 (37%), 15 (29%) and 9 (18%) patients, with three organ involvement at onset in 9 (17%) patients. All patients received systemic steroids prior to ECP for a median of 18 days (range, 10–91). Initial therapy consisted of 1 mg/kg or 2 mg/kg prednisone equivalent in 24 (46%) and 26 (50%) patients, respectively. Forty-one patients (79%) had either no or partial response after 7 days of steroid. ECP was administered as 2 treatments per week on a weekly to bi-weekly frequency and then stopped or tapered depending on response. Steroids were tapered at the discretion of the treating physician. Median number of ECP treatments was 12 (range, 2–45) given over a median duration of 55 days. Thirty-two (63%) patients responded to ECP (CR-26, 50%; PR-6, 12%). At the end of ECP treatment, grade 3–4 aGVHD was present in 17 patients (33%) with stage 3–4 involvement in skin (4, 8%), GI (10, 20%) and liver (10, 20%), respectively. The median steroid dose at termination of ECP in ECP-responders and non-responders was 0.15 mg/kg (range, 0–0.75) and 2 mg/kg (range, 0.15–2.3), respectively (P<0.001). ECP response: Donor type, stem cell source, aGVHD grade at onset, and organ –specific stage did not impact response. ECP response was superior for aGVHD developing after ablative regimen compared with reduced intensity/non-ablative regimens (76% vs. 48%, P=0.05). Patients with response at day 7 after initial steroid and subsequent steroid dependent aGVHD had a better response with ECP (80% vs. 50%, P=0.042). In logistic regression analyses, adjusted for regimen intensity, response at day 7 of initial steroid showed a trend for predicting ECP response (OR=4.22, 95% CI 0.95–18.7, P=0.058). Survival: Of the 52 patients, 28 (54%) are deceased (GVHD-19, relapse/progression-5, infections-4). The median follow up of the cohort after onset of ECP is 309 days (range, 12–1657). Median and 2-yr overall survival (measured from onset of ECP) is 442 days (95% CI, 0–993) and 42%. In univariate analyses, median survival after ECP onset was superior for patients who had an ablative transplant (not reached vs. 44 days, P=0.05), and had grade 2 or less aGVHD at onset (not reached vs. 79 days, P=0.028) (Fig. 1A). Indication of ECP (steroid dependent or refractory) did not impact survival. Patients with ECP response had a superior survival (measured from end of ECP) compared to non-responders (median survival, not reached vs. 14 days, P<0.001) (Fig. 1B) with a 65% 2-yr survival in ECP responders. In Cox proportional analyses, response to ECP was an independent predictor of survival (HR 0.091, 95% CI 0.034–0.263, P<0.001), after adjusting for regimen intensity and grade of aGVHD at onset. Conclusion: ECP is an effective steroid-sparing salvage therapy for patients with steroid dependent or refractory aGVHD with a response rate of 63% and 2-yr survival of 65% in responders. Based on this data, it is reasonable to undertake a prospective randomized study of ECP versus other agents, in patients with steroid dependent or refractory aGVHD.
