Abstract Introduction: Fludarabine plus rituximab (F-R) is an established treatment option for patients (pts) with relapsed/refractory follicular lymphoma (FL), other indolent lymphoma, or mantle cell lymphoma (MCL). To further improve the treatment in this setting we initiated in 2003 a multicenter, randomized phase III study to compare the efficacy and safety of bendamustine plus rituximab (B-R) versus F-R for pts with relapsed FL, other indolent lymphomas or MCL. Patients and Methods: 230 pts in need of treatment were randomized to rituximab 375 mg/m² (day 1) plus either bendamustine 90 mg/m² (days 1+2) or fludarabine 25 mg/m² (days 1–3) q 28 days for a maximum of 6 cycles. Prophylactic use of antibiotics or granulocyte-colony stimulating factor (G-CSF) was not generally recommended; however, in case of severe granulocytopenia, G-CSF use was permitted. The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS), overall response rate (ORR), and complete response rate (CR). The protocol was amended in 2006 to allow rituximab maintenance therapy (rituximab 375 mg/m2 q 3 months for up to 2 years) in both arms, following regulatory approvals in this setting. Results: A total of 219 pts were evaluable for the analysis (114 B-R; 105 F-R). There were no significant differences between arms for patient characteristics, including age, stage, LDH, IPI, FLIPI, bone marrow infiltration, and extranodal involvement. Most pts had stage IV (71.6% B-R; 60.6% F-R) or stage III disease (21.1% B-R; 25.3% F-R). Median patient age was 68 yrs (range 38–87). Patients had received a median of 1 prior therapy (range 1–7). Histological subtypes were distributed equally between the B-R and F-R arms: follicular, 45.9% and 47.5%, respectively; Waldenström’s Macroglobulinemia, 11.9% and 11.1%; MCL, 20.2% and 21.2%; other indolent lymphomas, 23% and 20.2%. A median of 6 cycles were given in both treatment arms, with 75.2% and 53.4% of B-R and F-R pts receiving 6 cycles, respectively. At the time of this analysis (June 2014), the median observation time was 96 months. The ORR was significantly higher with B-R than with F-R (83.5% vs. 52.5%, respectively; p< 0.0001). The CR rate with B-R was also significantly higher than that with F-R (38.5% vs. 16.2%; p=0.0004). Median PFS was significantly prolonged with B-R compared with F-R (34 vs. 12 months; hazard ratio [HR] 0.54, 95% confidence interval [CI] 0.38–0.72; p<0.0001). The longer PFS translated into a survival benefit with a significantly longer median overall survival in the B-R group than in the F-R group (110 vs. 49 months; HR 0.64, 95% CI 0.45–0.91; p=0.0125) comprising 55 and 71 deaths in the B-R and F-R groups, respectively. There were no significant differences in the rates of alopecia, stomatitis, erythema, allergic reactions, peripheral neuropathy, or infectious episodes between groups. Hematologic toxicities were also similar between arms: 8.9% grade 3/4 neutropenia with B-R vs. 9.1% with F-R; 11.8% grade 3/4 leukocytopenia with B-R vs. 12.4% with F-R. The overall incidence of serious adverse events was similar for the B-R and F-R groups (17.4% and 22.2%, respectively). 17 pts (14.9%) developed a secondary neoplasia after B-R compared with 16 pts (15.2%) after F-R. Of these, 5 pts in the B-R group, and 3 pts in the F-R group developed a secondary hematological neoplasia (2 AML [1 AML M4], 1 CML, 1 DLBCL, and 1 HD after B-R; and 2 AML M4, and 1 MDS after F-R). An unplanned subanalysis showed that rituximab maintenance therapy significantly prolonged overall survival (HR 0.38, 95% CI 0.32-0.71; p=0.0003) and PFS (HR 0.35, 95% CI 0.31-0.62; p< 0.0001) in the small group of 40 pts who received this treatment (23 B-R, 17 F-R) compared with those who did not. Although the numbers are too small in this non-randomized comparison to draw validated conclusions, these results appear to confirm the favorable role of rituximab maintenance. Conclusions: B-R was more effective than F-R in this setting of relapsed FL, other indolent lymphomas and MCL due to higher overall and complete response rates, a longer PFS, and an improved OS. These data confirm the high anti-lymphoma activity of B-R. Disclosures Off Label Use: Indication and dosage of bendamustine.

Abstract Abstract 856 Introduction: Promising results have been observed in two phase II studies evaluating the combination of bendamustine plus rituximab (B-R) in patients (pts) with relapsed/refractory follicular, other indolent or mantle cell lymphomas (MCL) (Rummel et al. JCO 2005; Robinson et al. JCO 2008). Fludarabine plus rituximab (F-R) is an established treatment option in this setting. Therefore, we initiated in 2003 a multicenter, randomized phase III study to compare the efficacy and safety of B-R versus F-R for pts with relapsed follicular (FL), indolent or MCL. Patients and methods: 219 pts with relapsed FL, indolent or MCL in need of treatment were randomized to rituximab 375 mg/m2 (day 1) plus either bendamustine 90 mg/m2 (days 1+2) or fludarabine 25 mg/m2 (days 1–3) q 28 days for a maximum of 6 cycles. Prophylactic use of antibiotics or granulocyte-colony stimulating factor (G-CSF) was not generally recommended; however in cases of severe granulocytopenia, G-CSF use was permitted. The primary endpoint was progression-free survival (PFS). The protocol was amended in 2006 to allow rituximab maintenance therapy (rituximab 375 mg/m2 q 3 months for up to 2 years) in both arms, following regulatory approvals in this setting. Results: 11 pts were not evaluable due to protocol violations, and were not followed further. A total of 208 pts were evaluable for the final analysis (109 B-R; 99 F-R). There were no significant differences between arms for patient characteristics, including age, stage, LDH, International Prognostic Index (IPI), follicular IPI (FLIPI), bone marrow infiltration and extranodal involvement. Most pts had stage IV (71.6% B-R; 60.6% F-R) or stage III disease (21.1% B-R and 25.3% F-R, respectively). Median patient age was 68 yrs (range 38–87). Patients had received a median of 1 prior therapy (range 1–7). Histological subtypes were distributed equally between the B-R and F-R arms: follicular 45.9 % and 47.5%, respectively; immunocytoma 11.9% and 11.1%; MCL 20.2% and 21.2%; other indolent lymphomas 23% and 20.2%. A median number of 6 cycles were given in both treatment arms, with 75.2% of B-R pts and 53.4% of F-R pts receiving 6 cycles, respectively. At the time of this analysis (June 2010), the median observation time was 33 months. Median PFS was significantly prolonged with B-R compared with F-R (30 vs 11 months; hazard ratio [HR] 0.51, 95 % confidence interval [CI] 0.34–0.67; p<0.0001). The overall response rate was significantly higher with B-R than with F-R (83.5 vs 52.5%, respectively; p< 0.0001). The CR rate with B-R was also significantly higher than that with F-R (38.5 vs 16.2%; p=0.0004). Overall survival did not differ significantly between arms, with 42 and 46 deaths documented in the B-R and F-R arms, respectively. There were no significant differences in the rates of alopecia, stomatitis, erythema, allergic reactions, peripheral neuropathy or infectious episodes between groups. Hematologic toxicities were also similar between arms: 8.9% grade 3/4 neutropenia with B-R vs 9.1% with F-R; 11.8% grade 3/4 leukocytopenia with B-R vs 12.4% with F-R. The overall incidence of serious adverse events was similar for the B-R and F-R groups (17.4 and 22.2%, respectively). An unplanned subanalysis showed that rituximab maintenance therapy significantly prolonged overall survival (HR 0.21, 95% CI 0.22–0.67; p=0.0008) and PFS (HR 0.27, 95% CI 0.27–0.59; p< 0.0001) in the small group of 40 pts who received this treatment (23 B-R, 17 F-R), compared with those who did not. Although the numbers are too small in this non-randomized comparison to draw some validated conclusions, these results appear to confirm the favorable role of rituximab maintenance. Conclusions: These data confirm the efficacy of B-R in pts with relapsed FL, indolent or MCL, and, in this setting, demonstrate a superior PFS benefit for this regimen in comparison with F-R. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 405 Introduction: Promising results have been observed in two phase-II studies evaluating the combination of Bendamustine plus Rituximab (B-R) in patients with relapsed/refractory indolent or mantle cell lymphomas (Rummel et al., JCO 2005; Robinson et al., JCO 2008). In order to further investigate the role of the combination B-R we initiated a multicenter randomized phase-III study in October 2003 to compare efficacy and safety of B-R versus CHOP plus Rituximab (CHOP-R) as first-line therapy for patients with follicular (FL), indolent and mantle cell lymphomas (MCL). Patients and Methods: 549 patients (pts) in need of treatment for their disease were randomized to receive Rituximab 375 mg/m2 (day 1) plus either Bendamustine 90 mg/m2 (days 1+2) every 28 days or the standard CHOP regimen every 21 days for a maximum of 6 cycles. The primary endpoint was progression-free survival (PFS). Patients characteristics, including age, stage, LDH, IPI, FLIPI, bone marrow infiltration and extranodal involvement did not statistically significant differ between both arms. The median patient age was 64 years (range 31-83) (64 yrs for B-R and 63 yrs for CHOP-R). Most patients were in stage IV (76,9% in BR and 77,5 in CHOP-R) and stage III (19,2% in B-R and 18,6% in CHOP-R). Histologies were distributed equally between B-R and CHOP-R: follicular 55% and 56%, mantle cell 18% and 19%, and other indolent lymphomas 27% and 24%, respectively. Prophylactic use of antibiotics or growth factors were not generally recommended in this protocol. Results: Of the 549 pts 36 pts were not evaluable: 10 did not receive any study medication, 9 due to withdrawal of consent, 13 due to incorrect diagnosis (4 × DLBCL, 3 × CLL, 2 × MM, 1 × HD, 3 × solid tumors), and 4 for other reasons. 513 randomized pts are evaluable for the final analysis (B-R: n=260; CHOP-R: n=253). Out of these 9 pts were not evaluable for response evaluation: 4 pts (3 × CHOP-R, 1 × B-R) due to early death in neutropenic sepsis, 3 pts due to a subsequent change of therapy after severe toxicity in 1st cycle of CHOP-R, 1 B-R pt due to progress of disease, and 1 B-R due to early death. All patients were counted for evaluation of PFS, overall survival (OS), event-free survival (EFS; an event was defined by a response less than a partial response, disease progression, relapse, or death from any cause), and for time to next treatment (TTNT). A median number of 6 cycles was given in both treatment arms each. 82% of B-R pts and 86% of CHOP-R pts received 6 cycles. At the time of analysis in August 2009, the median observation time was 32 months. Overall response rate for pts treated with B-R was similar to the CHOP-R group (93,8% vs 93,5%, respectively). The CR rate was significantly higher with 40,1% for B-R compared to 30,8% for CHOP-R (p=0.0323). The median PFS, EFS and TTNT were significantly longer after B-R compared to after CHOP-R: PFS 54,8 months for B-R versus (vs) 34,8 months for CHOP-R (p=0.0002), Hazard Ratio (HR) 0.5765 (95% confidence interval (CI) 0.4292 to 0.7683); EFS 54 months for B-R vs 31 months for CHOP-R (p=0.0002, HR 0.6014 (95% CI 0.4515 to 0.7845); and TTNT median not yet reached in the B-R group vs 40,7 months in the CHOP-R group (p=0.0002; HR 0.5416, 95% CI 0.3897 to 0.7491). OS did not differ between both groups at this point of time. Thus far, 67 deaths have been observed (B-R: 34; CHOP-R: 33). CHOP-R treatment was more frequently associated with serious adverse events (SAE) (n=49 in B-R vs n=74 in CHOP-R). Significant differences in hematologic toxicities were observed for neutropenia grade 3+4 (BR 10,7% vs CHOP-R 46,5%; p<0.0001) and for leukocytopenia grade 3+4 (BR 12,1% vs CHOP-R 38,2%; p<0.0001). G-CSF was more often used in CHOP-R treated pts (20,0% of all cycles) than it was used in the B-R group (4,0%) (p<0.0001). The B-R regimen was better tolerated by the pts as evidenced by a lower rate of alopecia (15% (only grade 1) in B-R vs 62% CHOP-R), a lower number of infectious complications (95 in BR vs 121 in CHOP-R, p=0.0403), a lower incidence of peripheral neuropathy (B-R n=18; CHOP-R n=73; p<0.0001), and fewer episodes of stomatitis (B-R n=16; CHOP-R n=47; p<0.0001). Only drug-associated erythematous skin reaction (urticaria, rash) was more often seen with B-R (n=42) than with CHOP-R (n=23) (p=0.0122). Conclusions: In this final analysis the combination of Bendamustine plus Rituximab improves PFS and CR rates while showing a better tolerability profile. These promising results suggest that B-R does have the potential to become a new standard first-line treatment option for patients with FL, MCL, and indolent lymphomas.

PURPOSE Romidepsin, a histone deacetylase inhibitor, has demonstrated activity in relapsed or refractory peripheral T-cell lymphoma (PTCL) as a single agent. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) therapy is widely used as first-line treatment of PTCL; however, it has limited efficacy. Results from a phase Ib and II study showed the feasibility of combining romidepsin with CHOP (Ro-CHOP). METHODS This study is a randomized phase III study of Ro-CHOP versus CHOP in adult patients with previously untreated PTCL. All patients received CHOP in 3-week cycles for six cycles. Romidepsin, 12 mg/m2, was administered intravenously over a 4-hour period on days 1 and 8 of each 3-week cycle for six cycles. The primary end point was progression-free survival (PFS) according to International Working Group 1999 criteria. RESULTS Between January 2013 and December 2017, 421 patients were enrolled (Ro-CHOP, n = 211; CHOP, n = 210). The median PFS for Ro-CHOP versus CHOP was 12.0 months (95% CI, 9.0 to 25.8) versus 10.2 months (95% CI, 7.4 to 13.2) with a hazard ratio of 0.81 ( P = .096). In the Ro-CHOP versus CHOP arms, the median overall survival was 51.8 versus 42.9 months and the objective response rate was 63% versus 60% with complete response plus unconfirmed complete response rates of 41% versus 37% ( P > .1 in all comparisons), respectively. Grade 3 or 4 treatment-emergent adverse events occurring in ≥ 30% of patients in the Ro-CHOP arm included thrombocytopenia (50% v 10% in the Ro-CHOP v CHOP arms, respectively), neutropenia (49% v 33%), anemia (47% v 17%), and leukopenia (32% v 20%). CONCLUSION The addition of romidepsin to CHOP did not improve PFS, response rates, nor overall survival and increased the frequency for grade ≥ 3 treatment-emergent adverse events. Ro-CHOP does not represent a significant advance in the standard of care for patients with previously untreated PTCL.

PURPOSE To determine the activity and evaluate the toxicity of uracil and tegafur in a 4:1 molar concentration (UFT; Taiho Pharmaceutical Ltd, Tokyo, Japan) plus oral calcium leucovorin in the treatment of patients with advanced colorectal carcinoma. PATIENTS AND METHODS Forty-five patients with advanced, bidimensionally measurable metastatic colorectal carcinoma were enrolled onto the trial. None of the patients had received prior chemotherapy or biologic therapy for advanced disease. Patients received either 350 or 300 mg/m2/d UFT plus 150 mg/d leucovorin administered orally in divided daily doses every 8 hours for 28 days followed by a 7-day rest period. Response was evaluated after two courses of therapy. RESULTS Eighteen patients (three treated at 350 mg/m2/d and 15 at 300 mg/m2/d) had partial responses, and one patient had a complete response (response rate, 42.2%; 95% confidence interval, 28% to 58%). Responses were observed in sites that included liver (n = 18), lung (n = 6), and bone (n = 1). Of seven patients who received 350 mg/m2 UFT, prolonged grade 3 diarrhea developed in five; this resulted in a reduction in the UFT starting dose to 300 mg/m2/d in the remaining 38 patients. Grade 1 or 2 toxic effects included diarrhea, nausea, vomiting, abdominal cramping, anorexia, fatigue, oral mucositis, excessive lacrimation, and rash. Among 38 patients who received the 300-mg/m2/d dose, grade 3 toxic reactions included diarrhea (n = 4), vomiting (n = 2), abdominal cramping (n = 1), and fatigue (n = 2). CONCLUSION UFT 300 mg/m2/d plus oral leucovorin 150 mg/d administered for 28 days demonstrated significant activity against metastatic colorectal carcinoma. This oral regimen was well tolerated and devoid of the neutropenia or significant oral mucositis that complicates intravenous schedules of fluorouracil (5-FU) plus leucovorin. The results of this clinical trial will serve as the basis for a randomized phase III study to compare this oral schedule of UFT plus leucovorin with intravenous 5-FU plus leucovorin to determine the relative efficacy, impact on quality of life, and cost of the two regimens.

PurposeDespite high initial remission rates, most lymphomas relapse and require further therapy. The mammalian target of rapamycin (mTOR) pathway is a validated target in mantle cell lymphoma, but has not been extensively evaluated in other lymphomas.Patients and MethodsWe performed a phase II trial of single-agent temsirolimus 25-mg weekly in patients with relapsed aggressive and indolent lymphomas. The primary objective was overall and complete response rate. Patients were stratified by histology: group A (diffuse large B-cell lymphoma, transformed follicular lymphoma), group B (follicular lymphoma), and group C (chronic lymphocytic leukemia/small lymphocytic lymphoma, and other indolent lymphomas).ResultsEighty-nine patients were treated, with outcome strongly dependent on histology. Group A had an overall and complete response rate of 28.1% and 12.5%, respectively, and median progression-free survival (PFS) of 2.6 months and median overall survival (OS) of 7.2 months. Group B had overall and complete response rates of 53.8% and 25.6%, respectively, and median PFS of 12.7 months; median OS has not yet been reached. Group C had a partial response rate of 11% with no complete responders. Toxicity was mainly mild and/or reversible myelosuppression and mucositis; however, four patients developed pneumonitis.ConclusionsSingle-agent temsirolimus has significant activity in both diffuse large B-cell lymphoma and follicular lymphoma, although the durability of responses and PFS are longer for patients with follicular lymphoma. This is the first report of substantial activity of temsirolimus in lymphomas other than mantle cell lymphoma, and supports further evaluation of mTOR as a target in these diseases.

Abstract Objective: The objective of this study was to evaluate the efficacy and safety of bendamustine HCl (TREANDA®) in combination with rituximab in patients with relapsed non-Hodgkin’s lymphoma (NHL). Background: Bendamustine is a novel hybrid, alkylating agent with single-agent activity in multiple hematologic and solid tumors. It induces cell death via both apoptosis and the apoptosis-independent pathway of mitotic catastrophe. The combination of bendamustine and rituximab has been shown to exhibit a synergistic antitumor effect on NHL cells. Methods: This Phase II, multicenter study enrolled adult patients with relapsed, indolent B-cell or mantle-cell NHL who were not refractory to rituximab (defined as progression ≤6 months of last rituximab dose). Patients received rituximab 375 mg/m2 intravenously (IV) on day 1 and bendamustine 90 mg/m2 IV on days 2 and 3 of a 28-day cycle for 4 to 6 cycles. An additional dose of rituximab 375 mg/m2 IV was given 1 week before the first cycle of bendamustine and 4 weeks after the last cycle. Results: The intent-to-treat (ITT) population included 66 patients (59% men) with a median age of 60 years (range, 40–84). Indolent histologic phenotype was seen in 54 patients with the following histologic subtypes: follicular center cell (61%), small lymphocytic (15%), lymphoplasmacytic (3%), and marginal zone (3%); 18% had mantle-cell lymphoma (MCL). A total of 85% of patients had stage III/IV disease. These patients relapsed from a median of 1 prior chemotherapy (range: 0–5), with 56% having had prior treatment with rituximab. Patients with no prior chemotherapy relapsed following biologic therapy. In the ITT population, the overall objective response rate (ORR) was 94% (complete response [CR]/complete response unconfirmed [CRu], 41%; partial response [PR], 53%); 6% had stable disease. The ORR for the 12 MCL patients was 92% (CR/CRu, 42%; PR 50%). For all patients, the median duration of response and progression-free survival has not been reached after a median follow-up of 8.3 months (range, 0.14–31 months). Grade 3/4 neutropenia was seen in 41% of patients (7%, febrile neutropenia). Common nonhematologic toxicities (grade 1/2, grade 3, grade 4) were nausea (68%, 0%, 0%) and fatigue (53%, 5%, 0%); one patient had grade 3 sepsis. No alopecia was observed. Conclusions: Bendamustine administered in combination with rituximab produced a high objective response rate and was generally well tolerated in patients with relapsed indolent and mantle-cell NHL who were not refractory to rituximab. These results suggest that the combination of bendamustine and rituximab may be comparable in activity to R-CHOP, and further studies of this combination are warranted.

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 5-azacytidine (AZA) significantly prolonged overall survival in higher-risk patients with myelodysplastic syndromes (MDS) in a large, international, randomized, phase III trial (AZA-001). However, data about efficacy and safety of AZA in lower risk MDS are less consistent and only few small studies have addressed this topic. Among a total of 246 MDS treated with AZA in 31 different Italian Institutions since 2005 within to a national patient named program, we evaluated 82 patients scored as low/int-1 IPSS risk MDS. Median age was 68 years (range 34–85), male/female ratio 50/32. According to WHO classification, there were 21 RA/RARS, 4 5q-syndromes, 20 RCMD, 24 RAEB-1, 5 RAEB-2, 4 CMMoL, and 4 MDS unclassified. Median time from diagnosis was 27 months (range 1–132). Sixty-eight patients (82.9%) were transfusion-dependent, sixty (74%) had received a prior treatment, mostly with erythropoiesis stimulating agents. AZA was administered as single drug in 61 patients (74.4%), while in the remaining subjects it was variously combined with growth factors, valproic acid or other agents. Forty-eight patients (58.5%) received a “standard” AZA dose of 75 mg/sqm/d s.c., thirty-four (41.5%) a fixed dose of 100 mg/d s.c. Single cycle treatment duration was 7 days in 45 patients (54.9%), &lt; 7 days in 32 patients (39%), &gt; 7 days in 3 patients (3.7%), unknown in 2 patients (2.4%). The median number of monthly cycles was 6 (range 1–21), and 63 patients (76.8%) completed at least 4 cycles. The most relevant toxicities observed (grade 3–4) were represented by myelosuppression (22%) and infections (6%). According to 2006-updated IWG criteria, overall response rate was 39% (47.5% in patients who had completed at least 4 cycles). In particular, complete response, partial response and hematological improvement occurred in 12.2%, 8.5% and 18.3% of patients (15.8%, 11.1% and 20.6% in those who were treated with at least 4 cycles), respectively. Stable or progressive disease was observed in 29.3%/25.6% and 30.2%/22.2% of patients receiving less than or at least 4 cycles, respectively. Response duration ranged from 1 to +21 months. There were no significant differences in response rate according to dose and schedule employed, although a slight trend in favour of 75 mg/sqm vs 100 mg fixed dose was seen (45.8% vs 29.4%, respectively). There was also no difference in the percentages of response according to age, previous treatment and transfusion dependence. Overall survival at 2 years was 62%. A survival benefit emerged for responding patients, compared to non responders (82% vs 57%) (p=0.015). A favourable trend was also observed for transfusion-independent patients, while age, pre-treatment and AZA dose did not influence survival. These data indicate that AZA may be safe and effective for a subset of patients with low/int-1 IPSS risk MDS, resistant or not suitable for alternative treatments. The efficacy may improve if at least 4 cycles are administered.

Abstract Abstract 1661 Poster Board I-687 Introduction One approach to improving outcomes in Mantle Cell Lymphoma (MCL) is to incorporate newer targeted agents into standard chemotherapy regimens. As the proteasome inhibitor bortezomib (Velcade‘) achieved a 33% response rate in relapsed MCL, we hypothesized that the incorporation of Velcade (Vc) into a modified R-hyperCVAD chemotherapy backbone would result in a high complete response rate (CR). The new regimen, VcR-CVAD, was tested for safety and efficacy in a phase II study within the Wisconsin Oncology Network (UW) and demonstrated a CR rate of 77% (Kahl, ASH 2008). To determine the safety and efficacy of this regimen in a cooperative group setting, we initiated E1405: a phase II study of VcR-CVAD with maintenance rituximab (MR) for untreated MCL. Methods Eligible patients had histologically confirmed, previously untreated MCL, PS 0-2, and adequate end organ function. The treatment plan included: Velcade 1.3 mg/m2 days 1 and 4, rituximab 375 mg/m2 IV day 1, cyclophosphamide 300 mg/m2 IV over 3 hrs q 12 hrs X 6 doses days 1-3, doxorubicin 50 mg/m2 continuous infusion over 48 hrs days 1-2, vincristine 1 mg IV day 3, dexamethasone 40 mg po days 1-4. Cycles were repeated every 21 days for 6 cycles and all patients received G-CSF support. Patients achieving SD, PR, or CR received MR administered as 4 weekly treatments every 6 months for 2 years (protocol therapy). Patients had an option to receive high dose chemotherapy and autologous stem cell transplantation (off protocol) rather than MR. The primary endpoint of the trial was the CR rate, incorporating PET imaging, to VcR-CVAD induction therapy. Results Seventy-six eligible patients were enrolled between 5/07 and 10/08. Baseline characteristics include median age 62 (40-76), 59M:17F, 91% stage III/IV, and 39% with elevated LDH. Sixty-four patients (84%) completed VcR-CVAD induction therapy. Reasons for treatment discontinuation included PD (1), toxicity (4), patient preference (2), and other/unknown (5). Response information is available on 74 patients while data is outstanding on 2 patients. The ORR was 96% (73/76; 95% CI, 89%-99%), CR rate 75% (57/76; 95% CI, 64%-84%) and the PR rate 21% (16/76; 95% CI, 13%-32%). Six of the PR patients were coded as such because of protocol violations in which a post-treatment bone marrow biopsy or PET scan was not obtained. The CR rate in the 68 completely restaged patients was 84%. Forty-four patients proceeded to planned MR while 21 patients went off protocol to SCT consolidation. Median follow up is currently too short (9 months) to assess PFS and OS. The major toxicity of the treatment regimen was expected myelosuppression. Grade 3-4 non hematologic toxicities were rare. No patients developed grade 3-4 neuropathy. There were no treatment related deaths. Conclusion The VcR-CVAD induction produced high overall response (96%) and CR rate (75%) in a representative MCL patient population treated on a cooperative group protocol. The CR rate was high and comparable to the UW pilot study (77%). No episodes of severe painful peripheral neuropathy were reported using the reduced vincristine dosage and the overall toxicity profile was very acceptable. Longer follow up is needed to determine if the high CR rate will translate into improved PFS and OS.

The Impact

3633 Background: TC is a treatment option for mCRC to improve the tumor response rate in selected patients (pts) and the conversion rate of initially non-resectable liver metastases. The aim of this study was to evaluate the impact and feasibility of FOLFIRINOX regimen in mCRC pts. Methods: All mCRC pts with non-resectable disease who have received FOLFIRINOX alone or combined with targeted therapies (bevacizumab or cetuximab) from October 2000 to December 2010 were selected for this analysis. Clinical data were collected in a mCRC specific data base and analyzed by the end of 2011. Results: Ninety two pts (52% of men), median age 59 yrs (range: 27-76) were treated with FOLFIRINOX (D1 oxaliplatin 85 mg/m² IV 2H then irinotecan 180 mg/m² IV 90 min and elvorin 200 mg/m², then 5FU 200 mg/m² and 2400 mg/m² by 46H infusion, D1=D15) alone (64%) or combined with cetuximab(30%) or bevacizumab (6%), as 1st-line in 82 pts (89%). Prophyllactic G-CSF was given in 58% of them. Primary tumor was located in colon (58%) or rectum (42%), and 64 (69%) of pts presented with synchronous metastases: liver 100%, lung 40%, peritoneum 17% and nodes 17%. Median number of cures was 8 (range: 1-12). There was 1 toxic death. Grade 3-4 toxicities were: diarrhea 22%, neuropathy 21%, cutaneous 12%, neutropenia 28%, febrile neutropenia 0%, thrombopenia 6%. Objective Response rate according to RECIST criteria was 72% [CI95% 61-81] including 10 pts with complete response (11%). The primary tumor was resected in 70 pts (76%) and 14% had KRAS mutated tumor. Among the pts with liver metastases, 63 (68%) pts were evaluated for secondary resectability by a multidisciplinary committee and 40 pts (43%) had resection achieved (70% R0). Median overall survival was 49 months [CI95%28-62]. Conclusions: These results confirm the feasibility of FOLFIRINOX regimen with or without targeted therapies and its efficacy in terms of response rate and overall survival as 1rst-line treatment in selected mCRC pts.
