LBA6501 Background: MF, a myeloproliferative neoplasm characterized by dysregulation of the JAK pathway, is associated with splenomegaly, constitutional symptoms and reduced lifespan. Ruxolitinib is a potent and selective JAK1 and JAK2 inhibitor. Methods: COMFORT-II, a randomized (2:1) phase III study, compared the efficacy and safety of ruxolitinib PO BID with BAT (other agents or no therapy) in adults with intermediate-2 or high-risk (Cervantes et al, Blood 2009) PMF, PPV-MF or PET-MF and palpable splenomegaly. The primary endpoint was the proportion of patients (pts), stratified by baseline risk category, achieving ≥ 35% reduction in spleen volume at week (wk) 48 determined by MRI or CT. The key secondary endpoint was the proportion achieving ≥ 35% reduction in spleen volume at wk 24. Results: 219 pts were randomized: 146 to ruxolitinib and 73 to BAT. Both arms included 49% high- and 51% intermediate-2 risk pts. The wk 48 response rate was 28.5% vs 0% (ruxolitinib vs BAT, P < .0001). The wk 24 response rate was 31.9% vs 0% (ruxolitinib vs BAT, P < .0001). Median duration of response to ruxolitinib was 48 wks. The most common (> 20%) adverse events (AEs) of any grade were (ruxolitinib vs BAT) thrombocytopenia (44.5% vs 9.6%), anemia (40.4% vs 12.3%), diarrhea (24.0% vs 11.0%), and peripheral edema (21.9% vs 26.0%). Grade 3-4 AEs occurring in ≥ 5% of pts in the ruxolitinib arm were: anemia (11%) and thrombocytopenia (7.5%). The most frequent grade 3-4 AEs in the BAT arm were anemia, thrombocytopenia, pneumonia and dyspnea (each 4.1%). Seven deaths occurred on treatment or within 28 days after end of treatment: 4 (2.7%) ruxolitinib and 3 (4.1%) BAT. Disposition of discontinuations were (ruxolitinib vs BAT) 8.2% vs 5.5% due to AEs and 1.4% vs 12.3% due to withdrawn consent. Conclusions: The COMFORT-II study demonstrates that ruxolitinib provides marked and sustained clinical benefit in spleen size and an acceptable safety profile relative to BAT, extends the positive results of COMFORT-I which compared ruxolitinib with placebo, and may result in a new standard of care for a large number of patients with MF.

8039 Background: AVAiL, an international placebo-controlled phase III trial, showed that Bv-based therapy significantly improved PFS and response rate in patients with advanced/recurrent NSCLC. This report summarizes overall safety findings from AVAiL. Methods: AVAiL randomized 1,043 patients with untreated locally advanced, metastatic or recurrent non-squamous NSCLC to C 80mg/m2 (d1) and G 1,250mg/m2 (d1 and d8) q3w for up to 6 cycles plus either Bv 7.5mg/kg q3w (n=331 with safety data), Bv 15mg/kg q3w (n=329) or placebo (n=326). Bv/placebo was administered until disease progression. Primary endpoint was PFS; secondary endpoints included OS, response rate, and safety. Safety was measured using NCI-CTC version 3.0 criteria for adverse events (AEs). Results: At final analysis, the median/maximum duration of Bv therapy was 4.9/28.5 mo (Bv 7.5) and 4.3/23.4 mo (Bv 15). The most common AEs overall were hematological and gastrointestinal (GI), and occurred in similar proportions of pts in the Bv and placebo arms. Grade ≥3 AEs occurred in 80%, 83%, and 77% of pts in the Bv 7.5, Bv 15 and placebo arms, respectively. The most common grade ≥3 adverse events were hematological, mainly neutropenia and thrombocytopenia. Neutropenia was reported in 43% (Bv 7.5), 40% (Bv 15) and 34% (placebo) of pts. Grade ≥3 AEs of special interest included hypertension (7%, 9% and 2%), proteinuria (2%, 3% and 0%), bleeding (4%, 5% and 2%) and hemoptysis (0.5%, 1.2% and 1.3%). The incidence of grade 5 hemoptysis was low (0.9%, 0.9% and 0% of pts, respectively). The incidence of GI perforations (<1%), thromboembolic events (≤8%), CHF (≤1%) and wound healing complications (<1%) was low and similar between treatment arms. The incidence of serious AEs was 39%, 45% and 36% in the Bv 7.5, Bv 15 and placebo arms, respectively. No new safety signals were reported. Conclusions: After E4599, AVAiL further demonstrated the efficacy of Bv in combination with platinum-based chemotherapy in the treatment of advanced NSCLC. Final safety data confirm the well established and manageable safety profile of Bv-based therapy in pts with advanced NSCLC. [Table: see text]

Abstract BACKGROUND. In primary myelofibrosis (PMF), survival from time of diagnosis is predicted by the international prognostic scoring system (IPSS), and from time of referral, by the dynamic IPSS (DIPSS) or DIPSS-plus. JAK2/CALR/MPL mutational status and presence and number of other prognostically-relevant mutations (ASXL1, SRSF2, EZH2, IDH1/2) provide IPSS/DIPSS-plus independent prognostic information. The objective in the current study was to revise IPSS, by including mutation-relevant prognostic information. METHODS. The study included 986 PMF patients divided into learning (n=588) and validation (n=398) cohorts. Previously published methods were used to screen for mutations involving JAK2,MPL, CALR, EZH2, ASXL1, IDH1/2 and SRSF2. The clinical variables assessed were those previously identified as being prognostically-relevant by IPSS or DIPSS-plus. The prognostic model (MIPSS) was developed through a stepwise selection process, based on a z-test of the regression coefficients, and its relative quality was measured by means of the Akaike information criterion. RESULTS. In the Italian learning cohort (n=588),median follow-up was 3.6years (95% CI, 0.03-30.8) for alive patients and 196 (33.3%) deaths and 67 leukemic transformations were documented. IPSS risk distribution was low in 26%, intermediate-1 in 30%, intermediate-2 in 24% and high in 20%. Mutational frequencies were approximately 63% for JAK2, 20% CALR, 6% MPL, 7% EZH2, 22% ASXL1, 2.5% IDH1/2 and 9% SRSF2. Constitutional symptoms were recorded in 28.6% of patients, splenomegaly 75% (18% >10cm from LCM) and grade 3 fibrosis 21%. Overall 252 patients were evaluable for karyotype and abnormalities were detected in 35%, including 9.5% unfavorable. Univariate analysis identified the following risk factors for inferior survival: age >60 years, constitutional symptoms, hemoglobin <100g/L, leukocytes >25x109/L, platelets <200x109/L, circulating blasts 1% or greater, splenomegaly >10cm, grade 3 fibrosis, unfavorable karyotype, triple-negativity for JAK2, MPL and CALR (TN), JAK2 or MPL mutation, and mutations in ASXL1, SRSF2, EZH2 or IDH1/2. In multivariable analysis, age >60 years, constitutional symptoms, hemoglobin <100g/L, platelets <200x109/L, TN, JAK2 or MPL mutation, ASXL1 and SRSF2 mutation remained significant; these variables were subsequently assigned the following HR-weighted adverse points: 1.5, 0.5, 0.5, 1.0, 1.5, 0.5, 0.5 and 0.5, respectively. Subsequently, four risk groups with no overlap in the 95% CI of their survival curves were delineated (Figure 1A): low (score 0-0.5); Intermediate-1 (score 1-1.5); Intermediate-2 (score 2-3.5); and high (score 4 or greater). The number of patients in each risk category, median survivals and HR and 95% CI values are included in figure 1A. Akaike information criterion indicated that MIPSS performed better than IPSS in predicting survival (1611.6 vs 1649.0). Leukemia-free survival was also predicted by high (p<0.01) and intermediate 1/2 (p<0.01) risk MIPSS. In the Mayo Clinic validation cohort (n=398), median age 63 years; males 64%,median follow-up for alive patients was 7.5 years and 271 (68%) deaths and 51 (13%) leukemic transformations were documented. DIPSS-plus risk distribution was low in 13%, intermediate-1 18%, intermediate-2 37% and high 32%. Mutational frequencies were approximately 51% for JAK2, 30% CALR, 7.5% MPL, 5% EZH2, 36% ASXL1, 5.6% IDH1/2 and 13% SRSF2. MIPSS performed equally well in this cohort, as illustrated in figure 1B, which includes number of patients in each risk category with their median survival and HR and 95% CI values. Leukemia-free survival in the Mayo cohort was also predicted by high (p<0.01) and intermediate-2 (p=0.04) risk MIPSS. Patients in the Mayo cohort were fully annotated for karyotype, which was MIPSS-independent in its prognostic value for both overall (p<0.01) and leukemia-free (p<0.01) survival. CONCLUSIONS. MIPSS addresses the mutation-relevant prognostic information gap in IPSS and performs equally well in the setting of patients seen at time of diagnosis or referral. Karyotype carries MIPSS-independent prognostic value that is recognized in an alternative GIPSS prognostic model (see accompanying ASH 2014 abstract), which complements MIPSS. Figure 1 Figure 1.

Abstract Abstract 538 Introduction: Recent data suggest that FCR immunochemotherapy improves response rates and Progression-Free Survival (PFS) of previously untreated CLL pts. The monoclonal antibody alemtuzumab, a humanized anti-CD52 antibody (Campath), has shown activity alone and in combination in CLL pts. In order to validate the place of Campath in combination with the synergic association FC, the FCGCLL/MW and the GOELAMS conducted a multicenter French and Belgian phase III trial, CLL2007FMP, to evaluate the efficacy and toxicity of FCCam versus FCR in previously untreated patients with advanced CLL. PFS was the primary-end-point of this trial. Methods and Patients: A cohort of 178 fit medically pts (cumulative illness rating scale (CIRS) score of up to 6), less than 65 years old, without 17p deletion, were enrolled between November 2007 and January 2009. Pts were randomly assigned to receive 6 oral courses of FC (F 40mg/m2 d1-3 and C 250 mg/m2 d1–3; q 28 days) in combination with either R (n=83; 375 mg/m2 i.v. d 0 at first cycle and 500 mg/m2 d1 all subsequent cycles; q 28 days) or Cam (n=82; 30 mg s/cut d1-3; q 28 days). Patients were stratified according to IgVH mutational status and 11q deletion. Anti-infective prophylaxis included trimethoprim-sulfamethoxazole and valaciclovir during immunochemotherapy and until the CD4-positive lymphocyte count reached 0,2 109/l. In the FCCAm arm, CMV monitoring was monthly performed by either PCR or antigenemia. The use of GSCF was recommended. The trial's recruitment was stopped in January 2009 after 165 pts had been randomized (83 and 82 respectively in the FCR and FCCam arms) because of an excess of mortality in the FCCam arm, while 13 patients were enrolled but not randomized because of this decision. Results: We reported here a preliminary analysis including baseline characteristics and response rates in the first 100 included pts but safety analysis of the whole cohort ; among the first 100 pts, 81% were Binet B, 19 % Binet C ; median age was 56.8 years (range 52.8 to 60.6). Percentages of pts with 11q deletion, unmutated IgVH status, and elevated β2m, were 18.5%, 48.4%, and 77.6%, respectively. A number of 76.5% (FCR arm) and 71.4% (FCCam arm) of pts received 6 cycles. Reasons for discontinuation were mainly related to persistent grade 3-4 neutropenia. Safety analysis data were availabel for 165 pts. Number of patients reported with Common Toxicity Criteria (CTC) grade 3-4 adverse events were observed in 87.8% (FCCam arm) versus 90.2% (FCR arm) (p = 0.76). Grade 3-4 neutropenia was the most frequently reported adverse event (79.6% with FCCam and 74.6% with FCR arm). Interestingly, percentage of observed grade 4 neutropenia was stable during FCR treatment (17.6% for cycle 1 and 17.9% for cycle 6) but increased during FCCam treatment (28.4% for cycle 1 and 45.5% for cycle 6). A total of 63 Serious Adverse events (SAE) were declared (19 with 18 pts in FCR arm, and 44 with 35 pts in FCCam arm) consisting mostly of the cases in febrile neutropenia (13 with FCR arm, 27 with FCCam arm); 7 patients died, all in the FCCam arm : 3 of B diffuse large B-cell lymphoma (one of them EBV positive), 1 of mucormycosis, 1 of septic shock due to P.aeruginosae and 2 of heart failure during neutropenia. The Overall Response Rate ( ORR) in the first 100 patients was 96% in the FCR arm compared to 85% in the FCCam arm (p=0.086). The Complete Response rate was 78% (FCR arm) versus 58% (FCCam arm) (p=0.072). PFS and OS are not yet evaluable. Conclusion: the FCCam regimen for the treatment of advanced CLL appeared to be associated with an unfavourable safety profile representing a significant limitation of its use in this indication. Other combinations with Alemtuzumab may be studied. Disclosures: No relevant conflicts of interest to declare.

PURPOSE: We conducted a randomized trial to compare gemcitabine-cisplatin with etoposide-cisplatin in the treatment of patients with advanced non–small-cell lung cancer (NSCLC). The primary end point of the comparison was response rate. PATIENTS AND METHODS: A total of 135 chemotherapy-naive patients with advanced NSCLC were randomized to receive either gemcitabine 1,250 mg/m2 intravenously (IV) days 1 and 8 or etoposide 100 mg/m2 IV days 1 to 3 along with cisplatin 100 mg/m2 IV day 1. Both treatments were administered in 21-day cycles. One hundred thirty-three patients were included in the intent-to-treat analysis of response. RESULTS: The response rate (externally validated) for patients given gemcitabine-cisplatin was superior to that for patients given etoposide-cisplatin (40.6% v 21.9%; P = .02). This superior response rate was associated with a significant delay in time to disease progression (6.9 months v 4.3 months; P = .01) without an impairment in quality of life (QOL). There was no statistically significant difference in survival time between both arms (8.7 months for gemcitabine-cisplatin v 7.2 months for etoposide-cisplatin; P = .18). The overall toxicity profile for both combinations of drugs was similar. Nausea and vomiting were reported more frequently in the gemcitabine arm than in the etoposide arm. However, the difference was not significant. Gemcitabine-cisplatin produced less grade 3 alopecia (13% v 51%) and less grade 4 neutropenia (28% v 56% ) but more grade 3 and 4 thrombocytopenia (56% v 13%) than did etoposide-cisplatin. However, there were no thrombocytopenia-related complications in the gemcitabine arm. CONCLUSION: Compared with etoposide-cisplatin, gemcitabine-cisplatin provides a significantly higher response rate and a delay in disease progression without impairing QOL in patients with advanced NSCLC.

PURPOSE To determine the response rate, survival, and toxicity of irinotecan (CPT-11), a topoisomerase I inhibitor, combined with etoposide, a topoisomerase II inhibitor, in refractory or relapsed small-cell lung cancer (SCLC). PATIENTS AND METHODS Twenty-five patients with refractory or relapsed SCLC were entered onto the trial. All 25 patients had been pretreated with some form of cisplatin-based combination chemotherapy and had also received previous etoposide- or anthracyclinecontaining chemotherapy. The median time off chemotherapy was 6.7 months (range, 0.9 to 23.5). Patients were treated at 4-week intervals using CPT-11 (a starting dose of 70 mg/m2 intravenously on days 1, 8, and 15) plus etoposide (80 mg/m2 intravenously on days 1 to 3), with a subsequent dose based on toxicity. In addition, recombinant human granulocyte colony-stimulating factor (rhG-CSF; 2 microg/kg/d) was given from day 4 to day 21, except on the days of CPT-11 administration. RESULTS All patients were assessable for toxicity and survival. Twenty-four patients were assessable for response. There were 14 partial responses (PRs) and three complete responses (CRs), for an overall response rate of 71% (95% confidence interval, 53% to 89%). The median response duration was 4.6 months. Median survival was 271 days. Major toxicities were myelosuppression (predominantly leukopenia) and diarrhea. Grade 3 to 4 neutropenia and thrombocytopenia occurred in 56% and 20% of patients, respectively. Grade 3 to 4 diarrhea was observed in 4%. There was one treatment-related death due to severe myelosuppression. CONCLUSION A combination of CPT-11 and etoposide with rhG-CSF support is an active therapy against refractory or relapsed SCLC and deserves to be studied more extensively in a phase III trial.

Abstract Several trials have shown the superior impact of high-dose melphalan (usually 200 mg/m2, MEL200) versus standard therapy in myeloma patients. Intermediate-dose melphalan (100 mg/m2, MEL100) was also superior to the standard dose, but MEL100 has not been clinically compared with MEL200 in a randomized study. In a case-matched study, response rate and event-free survival of MEL200 were superior to MEL100, but overall survival (OS) was similar. In this prospective, randomized, phase III trial, we compared the efficacy and toxicity of MEL200 and MEL100. Between January 2002 and July 2006, 299 patients were enrolled. Inclusion criteria were previously untreated myeloma, aged < 65 and Durie and Salmon stage II or III. Exclusion criteria were abnormal cardiac function, respiratory disease, abnormal liver function, abnormal renal function, HBV, HCV, or HIV positivity, concomitant cancer or psychiatric disease. The institutional review board approved the protocol and written informed consent was obtained from all patients. All patients received: 2 dexamethasone-doxorubicin-vincristine debulking courses (doxorubicin 50 mg/m2 day 1, vincristine 1 mg day 1, dexamethasone 40 mg days 1, 2, 3, 4, each course repeated every 28 days), 2 cycles of cyclophosphamide (4 g/m2, day 1) plus G-CSF followed by stem cell harvest. The MEL200 group was conditioned with 2 cycles of melphalan 200 mg/m2 followed by stem cell reinfusion; the MEL100 group was conditioned with 2 courses of melphalan 100 mg/m2 followed by stem cell reinfusion. At the present, 246 patients, median age 57 (range 32–65), completed the assigned therapy and were evaluated for response, progression-free survival (PFS) and OS. One-hundred and twenty-four patients were randomized to MEL200 and 122 to MEL100. Patient characteristics were similar in both groups. Abnormal cytogenetics (13q deletion, t(4;14), t(11;14), p53) were 75% in MEL200 patients and 56% in MEL100 patients (p=0.05). Forty-six patients did not complete tandem MEL200; 36 patients did not complete tandem MEL100. The near complete response rate of MEL200 was superior to MEL100 (32% versus 18%, p=0.011), but partial response was 80% versus 71%, respectively (p=0.079). The median follow-up for censored patients was 26.5 months. The 3 years PFS was 51% in the MEL200 arm and 33% in the MEL100 arm (HR=0.81, 95% CI 0.55–1.21, p=0.31). The 3 years OS was 86% in the MEL200 group and 71% in the MEL100 group (HR=0.82, 95 CI 0.45–1.48, p=0.51). Duration of grade 4 neutropenia and thrombocytopenia was comparable in two arms, but MEL200 patients required more platelet transfusions (p=0.03). Grade 3–4 non-hematological adverse events were reported in 49% of the MEL200 patients and in 38% of the MEL100 patients (P=0.07). The most frequent grade 3–4 adverse events were infections (54% of MEL200 patients versus 45% of MEL100 patients, p=0.25), mucositis (31% of MEL200 patients versus 7% of MEL100 patients, p=0.002) and gastrointestinal toxicities (20% of MEL200 patients versus 14% of MEL100 patients, p=0.3). In conclusion, MEL200 resulted in a significantly higher near complete response rate but this did not translate in a superior PFS and OS.

Abstract Standard front-line therapy for chronic lymphocytic leukemia (CLL) is fludarabine plus cyclophosphamide. Adding mitoxantrone (FCM) or rituximab (FCR) appears to improve responses although no large randomized trials have been reported. We report a randomized Phase II trial of FCM and FCM-R in relapsed CLL. FCM was oral fludarabine (24mg/m2 for 5 days) and cyclophosphamide (150mg/m2 for 5 days) plus i.v. mitoxantrone (6mg/m2) on Day 1 of each cycle. FCM-R was identical with rituximab on Day 1 of each cycle (375mg/m2 cycle 1; 500mg/m2 cycles 2 to 6). Prophylaxis with aciclovir and co-trimoxazole was given. The primary end-point was response by NCI Criteria 2 months after therapy. Complete remission with incomplete marrow recovery (CR(i)) was defined according to the 2007 CLL Guidelines - clinical CR with a morphologically normal marrow but persistent cytopenias (i.e. platelets <100x109/l and/or neutrophils <1.5x109/l). In addition, minimal residual disease in the marrow was studied 2 months after therapy by four-color flow cytometry with MRD negativity defined as <0.01% CLL cells. 52 patients were entered into the trial with 26 in each arm. The median age was 65 (32–79) with 79% men. 42% had a β2m >4. The median number of prior therapies was 2 (1–6), 31 had prior fludarabine and 6 (12%) were refractory to or relapsed <6 months after fludarabine. 26/44 (59%) had unmutated VH genes (15/22 FCM-R; 11/22 FCM). 11 patients had deletion of 11q (FCM-R 5, FCM 6) and 1 patient had >20% 17p deleted cells (FCM-R). 36/52 (69%) received 4 or more cycles of therapy with no difference between FCM and FCM-R (18/26). Responses are shown in the Table. 35 SAE’s were reported in 23 patients. There was no difference in the number of patients with SAE’s between the arms (FCM 11, FCM-R 12). 6/7 patients (86%) who had 4 or more prior therapies reported an SAE, compared to 17/45 patients (38%) who had less than 4. 16 SAE’s were suspected to be related to FCM-R and 10 related to FCM. In summary, FCM-R is an effective therapy for relapsed CLL with over two-thirds of patients responding. The study design does not allow a statistical comparison between FCM and FCM-R but the results suggest that adding rituximab to FCM results in a higher complete response rate (CR + CR i = 43% for FCM-R and 13% for FCM) with more patients achieving MRD negativity (5 after FCM-R; 2 after FCM). The results of this randomised Phase II trial justify the study of FC with mitoxantrone and/or rituximab in larger randomized Phase III trials.

Abstract Abstract 258 This randomized phase III clinical trial was designed to evaluate the potential benefit and toxicity of (a) arsenic trioxide (ATO) as initial consolidation therapy and (b) maintenance therapy with oral tretinoin (ATRA) either alone or together with 6-mercaptopurine (MP) and methotrexate (MTX) in newly diagnosed patients with APL. All patients received induction therapy with ATRA, daunorubicin (DNR) and cytarabine. Adults (≥ 15 years) were randomized at study entry to receive a standard consolidation with 2 courses of ATRA plus DNR, or 2 courses of ATO as initial consolidation followed by 2 courses of ATRA plus DNR. Patients who remained in complete remission (CR; n=331) were then randomized (stratified by consolidation arm and age group) to one year of maintenance with ATRA alone (45 mg/m2/d) for 7 days repeated every other week (n=166) or in combination with MP 60 mg/m2/daily plus oral MTX 20 mg/m2/weekly (n=161). The target number of maintenance events was 146, and the study had 80% power to detect a hazard ratio of 1.6 at 5 years. We previously reported that the addition of ATO consolidation markedly improved event-free (EFS) and disease-free (DFS) survival (Blood 2010; 116:3751–3757). We now report the results of the maintenance randomization after a median follow up of 6.2 years. The two groups were well balanced by pretreatment characteristics. DFS, the primary endpoint, and overall survival (OS) were not statistically different for the two maintenance arms (log-rank p=0.14 and p=0.33, respectively). Evaluation by consolidation arm (by intention-to-treat, ITT) and by APL risk group also failed to demonstrate a significant advantage for either maintenance treatment. There was no interaction effect between consolidation and maintenance arms (p=0.78). Age, gender, CD56 expression and FLT3-ITD or TKD mutations at diagnosis did not have an impact on outcome by maintenance arm.ATRA*ATRA/MP/MTX*PDFS: overall41/16630/1610.14DFS by consolidation arm (ITT): ATO10/844/780.13no ATO31/8226/830.21DFS by risk group: low/intermediate25/12819/1300.20high16/3811/310.683-year DFS from CR79%87%0.056OS: overall22/16616/1650.33OS by consolidation arm (ITT): ATO8/843/810.15no ATO14/8213/840.72OS by risk group: low/intermediate14/1289/1340.20high8/387/310.733-year OS from study entry92%95%0.28*Number of events/number of patients in each group or subgroup. No treatment-related deaths were reported during maintenance therapy. Hematologic adverse events were more common in the combination arm (maximum grade 3/4, 18% vs 4%; p< 0.0001), as were non-hematologic adverse events (maximum grade 3/4, 36% vs 25%; p=0.033). Only 71 DFS events have occurred to date. Although the 3-yr DFS favors the combination arm, the differences in DFS and OS with the addition of MP and MTX to ATRA maintenance do not reach statistical significance. The addition of ATO consolidation therapy remains the most important determinant of DFS and OS for APL patients in first remission on this randomized trial. Among patients who were randomized to maintenance, only 5 patients who received ATO consolidation have relapsed – 2 from the combination arm and 3 from the ATRA alone arm. Relapse of APL is uncommon in patients who received ATO consolidation, and the need for any maintenance therapy in these patients has yet to be determined.

Abstract Abstract 279 Background: COMFORT-II is a randomized, open-label, phase 3 study evaluating the safety and efficacy of ruxolitinib, a potent and selective oral inhibitor of JAK1 and JAK2, in patients with primary myelofibrosis (PMF), post-polycythemia vera-MF (PPV-MF), or post-essential thrombocythemia-MF (PET-MF). Patients who received ruxolitinib had significantly greater reductions in spleen volume compared with those who received best available therapy (BAT). The primary and key secondary endpoints of the study were both met: the proportion of patients achieving ≥35% reduction in spleen volume at week 48 (28.5%, ruxolitinib; 0%, BAT; P <.0001) and week 24 (31.9%, ruxolitinib; 0%, BAT; P <.0001), respectively. Subgroup analysis was performed on both the 48- and 24-week endpoints. Methods: In the COMFORT-II study, 219 patients were randomized (2:1) to receive ruxolitinib (15 or 20 mg twice daily [bid] based on the baseline platelet count [100– 200 × 109/L or >200 × 109/L, respectively]) or BAT of the investigator's choice. The proportions of ruxolitinib-treated patients achieving the primary and key secondary endpoints were analyzed by subgroup for gender (male or female), age (≤65 or >65 years), starting dose (15 or 20 mg bid), baseline MF type (PMF, PPV-MF, or PET-MF), previous hydroxyurea (hydroxycarbamide) use (yes or no), baseline palpable spleen length (≤10 or >10 cm), baseline spleen volume (>median or ≤median), JAK2V617F mutation (presence or absence), and International Prognostic Scoring System (IPSS) risk category (intermediate-2 or high) (Cervantes F, et al, Blood, 2009;113(13):2895–2901). In addition, the relationships between these factors and spleen volume reduction were investigated by multivariate logistic regression. Results: The proportion of patients in each subgroup with ≥ 35% reduction in spleen volume from baseline at week 48 is shown below (Figure). BL, baseline; HU, hydroxyurea. The response rate was higher in patients receiving ruxolitinib than in patients receiving BAT in all subgroups; no patients in the BAT group reached a ≥35% reduction in spleen volume at week 48. All subgroups receiving ruxolitinib responded and all subgroup comparisons had overlapping 95% confidence intervals. At week 24, a trend for a higher response rate was observed in patients who received a starting dose of 20 mg bid compared with those who received a starting dose of 15 mg bid; however, the response rates among these patients at week 48 were not different. No significant difference in response rates was observed between patients with the JAK2V617F mutation compared with those without the mutation. Results of the subgroup analysis were confirmed by the multivariate models. A significant effect of the ruxolitinib starting dose was seen when response rates were modeled at week 24 but not when modeled at week 48. Conclusions: Recent findings from the COMFORT-II study show that patients who received ruxolitinib had significantly greater reductions in splenomegaly than did patients who received BAT. In this analysis, ruxolitinib was shown to be more effective than BAT at reducing spleen volume in all patient subgroups regardless of gender, age, mutation status, IPSS risk category, baseline spleen size, MF subtype, or ruxolitinib starting dose.

8505 Background: High dose IFNa regimen as reported in E1684 was unique for the incorporation of an induction phase of maximally-tolerated dosages of IV therapy for the initial 4 weeks. This is the only trial that has shown prolongation of overall survival and disease-free survival in comparison to observation. Analysis of the hazard curves for DFS and OS in E1684 reveal early and durable separation of the high-dose and observation arms suggesting that the induction phase may represent a critical component of the high-dose regimen, although this has not been tested prospectively. Methods: We conducted a prospective randomized study of IV induction therapy vs a full year of high-dose IFN with primary endpoints of DFS and OS for stage IIB, IIC and III melanoma patients within 56 days of curative surgery. Patients were randomized to receive IFN alfa-2b 15×106 U/m2 IV × 5/7 days weekly × 4 weeks (arm A) versus the same regimen followed by 10×106 U(flat dose) SC 3 times a week for 48 weeks (arm B). The proposed treatment would be considered at least as good as the conventional treatment, if the relapse rate at 3 years from study entry is at most 15% higher in the former arm (power 85%, one-sided test a=0.05, required sample size: 340). Results: Between 1998 and 2004, 364 patients were enrolled (355 eligible: 178 arm A and 177 arm B). Patients′ and tumor characteristics were well balanced between the two arms. At a median follow up of 51 months (95% CI 46–55), the median DFS is 32 months vs 31 months (p=0.836) and the median OS is 61 months vs 63 months (p=0.444). Eleven patients discontinued treatment in arm A and 54 in arm B. The discontinuation rate is significantly higher in group B (p<0.001), possibly due to the longer duration. Reasons for discontinuation were disease progression (69%) and toxicity (19%). Patients in arm B had more grade 3–4 hematologic, constitutional and neurologic toxicity. Conclusions: There are no significant differences in OS and DFS between the regimen of 1 month and 1 year treatment tested. [Table: see text]
