6592 Background: Treatment of AML in patients (pts) > 70 yrs of age with intensive chemotherapy is associated with high rates of early mortality and little benefit. Newer, lower-intensity approaches with novel mechanisms are needed. OM is a semisynthetic plant alkaloid which has demonstrated activity in AML as a single agent and with chemotherapy. Methods: We studied a low intensity program combining subcutaneous (SQ) OM with SQ LDAC in pts >/= 60 yrs, with AML or MDS, a performance status (PS) of </=2, and adequate organ function. Initially, 6 pts were enrolled at the following doses: OM 1.25 mg/m2 SQ Q12 hrs x 3 days with AraC 20 mg SQ Q12 hrs x 7 days on a 4 week cycle. If safety is confirmed, the phase II portion would commence at the safe dose levels. Up to 12 courses can be given. The primary endpoint was to determine the complete remission (CR) rate. Secondary endpoints were: CR duration, DFS, OS, safety, and early mortality. Results: 17 pts were enrolled on study so far. The median age was 74 yrs (range, 64-81); the median PS was 1 (0-1). The karyotypes in these pts were: diploid in 6 (35%), complex with chromosome (chr) 5 and/or 7 abnormality (abnl) in 4 (24%), complex without chr 5 and/or 7 abnl in 2 (12%), 11q abnl in 1 (6%), poor metaphases in 1 (6%), and other in 3 (18%). Four pts with prior MDS were treated with a median of 2 prior therapies (1-3). Median bone marrow blast % at the start of therapy was 40 (15-87). The median WBC, hemoglobin, and platelets were 2.1 (0.4–24.8), 8.9 (7.7–10.7), and 45 (14–104), respectively. These pts have received a median of 1 (1-3) cycle of therapy. Of the 11 pts evaluable for response, there were 2(18%) CR, 1(9%) CRp, 1(9%) PR for an ORR of 4/11 (36%). Five pts had no response and were taken off study. Two pts died on study: 1 on day 6 and 1 on day 27. Both pts were 74 yrs with a complex karyotype. One died of pneumonia and multi-organ failure and the 2nd died from cardiac arrest. Other than the deaths, serious adverse events included grade 3 transaminitis in 1 and grade 3 heart failure in 1. Conclusions: OM and LDAC appears to be tolerable in older pts with AML. The combination appears to have activity. Stopping boundaries for futility and safety have not been breached. Enrollment is ongoing.

8010 Background: Bortezomib is the first proteasome inhibitor that showed promising activity in hematologic malignancies. In Jan 2005, we initiated a phase II randomized trial to evaluate front-line R-CHOP + bortezomib in B lymphoma pts. Methods: 6 cycles of standard R-CHOP (d1=d21) were planned, pts were randomized between 2 schedules of bortezomib: arm A (d 1,4,8,11), arm B (d 1,8). For the first 24 pts (step1), bortezomib was administred at 1 mg/m2 in arm A and 1.3 mg/m2 in arm B. For the next 24 pts (step2), it was increased at 1.3 mg/m2 and 1.6 mg/m2 respectively. G-CSF and EPO supports were allowed. Primary endpoint was CR rate after 6 cycles. Results: The trial was closed in Apr 2006 after inclusion of 49 pts. Sex ratio M/F was 28 /21. Median age: 63 years [32–76]. Pathology: 4 Lymphoplasmocytic, 4 small lymphocyte, 8 MZL, 2 Malt, 11 FL , 7 FL with histological transformation, 4 Mantle cell and 9 DLBC without adverse factor. Performance status 2–4: 4 pts; stage 4: 33 pts; LDH>N: 16 pts and IPI 2–3: 18 pts. According to triangular-test interim analysis (Jan 2006), arm A was closed at 20 pts (11 step1, 9 step2). 29 pts received arm B (10 step1, 19 step2). 290 cycles of R- CHOP and 819 injections of bortezomid were given. In arm A, 5/20 pts received less than 90% of scheduled dose of bortezomib (all in step2); in arm B, 7/29 pts (2 step1 and 5 step2). Grade 3–4 thrombopenia occurred in 14% of cycles (35% arm A, 0% arm B, 14% step2), Grade 3–4 leucopenia in 41 % (35% arm A, 45% arm B, 43% step2). Neurological toxicity occurred in 21 pts: grade 2 in 11 (1 arm A, 10 arm B, 9 in step2) and grade 3–4 in 10 (5 arm A, 5 arm B, 9 in step 2). 6 of them were considered as serious adverse events. Other grade 3–4 toxicities were 1 constipation (1 arm B, step2), 3 infections (2 arm A, 1 arm B, 2 step 2) and 2 cardiac events (1 arm A, 1 arm B). 48 pts were evaluable for response: 40 achieved CR/CRU: 18/20 in arm A, 22/28 in arm B. There were 5 PR (1 arm A, 4 arm B), 1 SD (arm A) and 2 PD (arm B). 19/21 pts achieved CR in step 1 and 21/27 in step 2. After 1 year median follow up, OS was 100% and EFS 80%. Conclusions: R- CHOP+Bortezomid is an effective regimen with 83% CR rate. However, the higher doses of bortezomib lead to severe neuropathy and suggest that association with vinca alcaloides should be avoided. No significant financial relationships to disclose.

7718 Background: Gemcitabine and irinotecan has been shown to have an antitumor activity as a single agent against previously treated SCLC. The objective of this study was to assess the efficacy and safety of gemcitabine combined with irinotecan in patients with refractory or relapsed SCLC. Methods: Patients with histologically or cytologically confirmed SCLC, 20 to 74 years in age, performance status 0–2, with a history of receiving one platinum-based chemotherapy were eligible for the study. Treatment consisted of gemcitabine (1,000 mg/m2) and irinotecan (150 mg/m2) on days 1 and 15 of a 28-day cycle.The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 30 patients (Simon's two-stage minimax design). Results: Thirty-one patients were enrolled and 30 patients (24 males/6 females, 10 refractory/20 sensitive, median age, 65 years) receive protocol treatment in this phase II trial. The median treatment cycles were 3 (1–10). The overall response rates was obtained in 39.3% (95% CI: 18.1% to 60.5%) of the patients, including two patients with refractory disease and 9 patients with sensitive disease. The median overall survival time was 14.4 months, and the 1-year survival rate was 51%. The median survival time of the patients with refractory disease was 7.4 months, compared with 14.4 months for patients with sensitive disease. The chief grade 3/4 toxicities included neutropenia (42%), thrombocytopenia (3%), diarrhea (9%), and liver dysfunction (3%). The only grade 4 toxicities were one case of grade 4 neutropenia (3.3%) and one case of grade 4 thrombocytopenia (3.3%). Conclusion: Gemcitabine plus irinotecan is an active regimen that seems to be well- tolerated by patients with previously treated SCLC. No significant financial relationships to disclose.

2009 Background: Gimatecan is a highly lipophilic oral camptothecin analogue with impressive preclinical activity in glioma models. Methods: We conducted a multicenter two-stage phase II trial to evaluate the efficacy of gimatecan in adults with recurrent glioblastoma. Eligibility criteria included ≤1 prior treatment for recurrent disease, age ≥18, ECOG performance status 0 or 1, and normal organ function. Patients taking enzyme-inducing anti-seizure medications were excluded. Gimatecan 1.22 mg/m2 was given orally once daily for 5 consecutive days during each 28-day cycle. Radiographic response was evaluated by MRI after every second cycle. The primary endpoint of the study was 6 months PFS. A Simon's 2-stage design was used in which 19 patients were evaluated in the first stage, with an additional 36 patients accrued if > 4 patients in stage 1 achieved 6 month PFS. Results: A total of 29 patients were enrolled in the study, with median age of 58 years (range, 25–77 years); 58.6% female; all of whom had received prior surgery, radiation therapy, and at least one regimen of chemotherapy. The daily dose was reduced to 1.0 mg/m2 after four of the first 10 patients experienced grade 4 hematologic toxicity. One patient was removed from trial due to toxicity (grade 3 leukopenia and thrombocytopenia). Treatment delay occurred in 11 patients (38%) and dose reduction was necessary in eight patients (28%). Treatment-related grade 3/4 toxicities included thrombocytopenia (17.2%), leukopenia (17.2%), and neutropenia (10.3%). Only 1/19 patients treated with 1.0 mg/m2/day experienced grade 3/4 hematologic toxicity. The 18% reduction in the daily dose resulted in a 19% decrease in the concentration of total gimatecan in plasma prior to administration of the fifth daily dose (56 ± 23 vs. 45 ± 20 ng/mL) and a 33% decrease in the AUC for dose 5 (8.0±4.8 vs. 5.3±4.2 ng*h/mL). Only one patient had a partial radiographic response by the modified Macdonald criteria and stable disease was the best response in 13 patients. All other patients had progressive disease after two cycles of therapy. Only three patients (12%) were progression-free at 6 months. Median time to progression was 12.0 weeks (95% CI: 7.0, 17.0). Conclusions: Treatment with single-agent gimatecan 1.0 mg/m2/day for 5 days, repeated every 28-days showed minimal efficacy. [Table: see text]

4606 Background: Metastatic pancreas cancer (MPC) remains identified with poor outcome. Benchmark response statistics in MPC include response rate (RR) 20–30%, time to disease progression (TTP) 3.5–5.5 mo, median overall survival (OS) 6–9 mo and 1- year (yr) OS 20–30%. At our center, adding docetaxel (D) to G in MPC produced 6.0 mo TTP and 10.5 mo OS (Jacobs et.al. Canc Invest 2004). As bevacizumab (B) added to combination chemotherapy has produced major improvement in OS for other cancers (e.g. colon cancer), we chose to study the GDB regimen in MPC. Methods: Our study was phase II, single-phase. Eligiblity criteria included 1) diagnosis of MPC, 2) chemotherapy naivity, 3) ECOG performance status 0 /1, 4) organ function adequate for therapy. Therapy included G 1000 mg/m2 IV bolus, D 40 mg/m2 IV and B 10 mg/kg IV every 2 weeks (wks) for 1 yr unless disease progression or prohibitive treatment toxicity occurred. Patients were radiographically restaged every 8 wks. Primary endpoint was TTP. Secondary endpoints included therapy toxicity, radiographic RR (RECIST criteria), tumor marker RR (CA 19.9) and OS. Results: Of 27 enrolled patients (pts), 25 pts are currently evaluable for response, 24 pts for TTP. Median age is 58 yrs. Primary metastatic disease sites were liver (n=18), peritoneum ( n=6), lymph node ( n=2) and lung (n=1). 7/27 pts (26%) experienced grade 3 or higher treatment-related toxicity, including pulmonary (n=3), neutropenia (n=3), bleeding events (n=3), VTE (n=2), hypertension (n=1), hypokalemia (n=1) and skin rash (n=1). 1 pt died from respiratory failure, possibly therapy-related. To date, disease control at 8 wks is 100% (24/24 pts) radiographic RR is 48% (12/25 pts) and tumor marker RR is 95% (18/19 evaluable pts expressed CA19.9, median decline 80%, 5 pts normalized) . Of 24 pts evaluable for TTP, 9/18 (50%) initial pts achieved > 9 mo TTP (range 9.2–18.5 mo); the remaining 6 pts continue progression-free on therapy (range 2+-7+ mo). Median OS has not been reached and will be > 8.3 mo. Response data will be updated at the meeting. Conclusions: 1) The GDB regimen is overall well-tolerated; pulmonary toxicity was the major therapy-related toxicity concern. 2) GDB is significantly active in MPC as witnessed by response rates achieved. 3) Further study of the GDB regimen in MPC is warranted.

7081 Background: Cisplatin is one of the most active drugs available in MPM while bortezomib has shown some activity in single agent phase II studies against MPM. This was a prospective phase II study of cisplatin and bortezomib (CB) in the first line treatment of MPM. Methods: Patients with histological proven MPM, with performance status (PS) 0/1, were eligible. The doses were cisplatin 75mg/m2 /3 wks and bortezomib 1.3mg/m2 day 1, 4, 8, 11 every 3 wks. The primary end-point was progression free survival rate at 18 wks (PFSR=18). The 2-stage Simon design (a=0.1; b = 0.05, P0=0.50 and P1=0.675) was used. In the first step of the study 37 eligible patients were planned. If more than 19 patients were alive and free of progression at 18 wks the total sample size was increased to 76 eligible patients. Results: Between 2007 and 2010 82 patients were entered. The median follow-up time is 32.3 months The median age was 55 years (range: 22-77yrs), male/female: 55/27 , PS 0/1: 9/73, Stage T1: 10%; T2: 42%, T3: 25%; T4: 23% and N0: 57%; N1: 4%; N2: 33%; N3: 6%. The median number of cycles received was 4 and 38% received 6 cycles. Cisplatin/ bortezomib dose intensity was 98/ 80%. Toxicity (grade 3/4): neutropenia 10%, thrombocytopenia 11%, anaemia 1%. Grade 3-4 hyponatraemia/ hypokalaemia occurred in 46/ and 17%. Grade 2 tinnitus, grade 3 fatigue occurred in 16%, and 12%, of patients. Motor/sensory/other neurotoxicity was grade 1: 6/28/7%, grade 2: 2/26/2% and grade 3: 1/7/2% respectively. There were 2 toxic deaths at 32 and 74 days due to acute pneumonitis and cardiac arrest. The PFRS-18 (including symptomatic progression) was 53% (80% confidence intervals, CI, 42-64%). The overall survival was 13.5 months (95% CI 10.5-15) with 56% (95% CI 44-66%) alive at 1 year. The PFS was 5.1 months (95% CI 3.3-6.5). Conclusions: On the basis of the PFRS-18, the null hypothesis could not be rejected, although CB gave predictable toxicity and was as active as other reported regimens in MPM.

3600 Background: CASAD is a naturally occurring calcium montmorrilonite clay that serves as a cation exchange absorbent. One of the active metabolites of Irinotecan is SN-38, which is adsorbed by CASAD in vitro. The study hypothesis was that oral CASAD would reduce the rate of grade 3/4 diarrhea in mCRC patients treated with irinotecan. Methods: The study is a multicenter, prospective, randomized, double blinded placebo-controlled phase II trial. One hundred patients receiving I-based chemotherapy were randomized equally between CASAD (1000 mg po 4x daily) and placebo in order to have 75% power to detect a difference in the proportions of patients with grade 3/4 diarrhea within 6 weeks at a 1-sided 5% significance level. We also compared symptom burden using the MDASI questionnaire summed over the 13 symptom items for weeks 0, 3, 5, and 6. Results: Between 5/2009 and 5/2012, 100 patients were randomized in a 1:1 ratio between study arms. Median age 57 yrs, 54% male, 74% Non-Hispanic White, 93% performance status 0 or 1. Serious diarrhea was less frequent than expected based upon prior studies with Irinotecan. In evaluable patients, no significant difference in the rate of G3/4 diarrhea was seen (the primary endpoint): CASAD arm: 7/43 pts (16%), Placebo arm: 3/32 pts (9%), p=0.70. The rate of any diarrhea among all pts was also similar: CASAD arm 64% vs. Placebo arm 70%. The rate of study dropout was 14% in CASAD and 38% for placebo (p=0.01; 2-sided). No differences were found in symptom burden or individual symptom items or serious adverse events. Conclusions: Compared with placebo, CASAD use was safe but ineffective in preventing diarrhea in mCRC patients treated with irinotecan-containing chemotherapy regimens. There were no favorable or unfavorable signals in terms of the patient experience related to symptoms, but there were significantly more dropouts in the placebo arm. Future CASAD trials are focused on active treatment of diarrhea. Clinical trial information: NCT00748215.

Abstract The rates of expected serious adverse events in patients with acute leukemia on chemotherapy far exceed those in patients with solid tumors. Regulatory authorities require similar reporting criteria, which overburden the investigators and infrastructure with unnecessary documentation. To establish a baseline for expected toxicities before and during leukemia therapy, we reviewed 1534 adults with acute myeloid leukemia (AML; excluding acute promyelocytic leukemia) from 1990 to 2006 who received frontline intensive chemotherapy; 723 (47%) were 60 years or older. Prior to therapy, grade 3/4 cytopenias were observed in 86% of patients. All patients developed one or more grade 3/4 cytopenias during therapy, and more than 90% had a febrile episode. Admission to the intensive care unit, mechanical ventilation, and dialysis were required in 28%, 16%, and 7%, respectively. Mortality during induction, 2-week mortality, and 6-week mortality were 20%, 5%, and 16%, respectively. Grade 3/4 renal or hepatic toxicities were observed in 3% and 22% of patients, respectively. Other grade 3 or 4 toxicities were also common before treatment and during therapy. This paper establishes a baseline toxicity rate for patients with AML during induction therapy, and this could be used as a control group for future reference. Guidelines for reporting adverse events in leukemia studies should be revisited.

This study investigated the efficacy and safety of pimasertib (MEK1/MEK2 inhibitor) versus dacarbazine (DTIC) in patients with untreated NRAS-mutated melanoma. Phase II, multicenter, open-label trial. Patients with unresectable, stage IIIc/IVM1 NRAS-mutated cutaneous melanoma were randomized 2:1 to pimasertib (60 mg; oral twice-daily) or DTIC (1000 mg/m2; intravenously) on Day 1 of each 21-day cycle. Patients progressing on DTIC could crossover to pimasertib. Primary endpoint: investigator-assessed progression-free survival (PFS); secondary endpoints: overall survival (OS), objective response rate (ORR), quality of life (QoL), and safety. Overall, 194 patients were randomized (pimasertib n = 130, DTIC n = 64), and 191 received treatment (pimasertib n = 130, DTIC n = 61). PFS was significantly improved with pimasertib versus DTIC (median 13 versus 7 weeks, respectively; hazard ratio (HR) 0.59, 95% confidence interval (CI) 0.42–0.83; p = 0.0022). ORR was improved with pimasertib (odds ratio 2.24, 95% CI 1.00–4.98; p = 0.0453). OS was similar between treatments (median 9 versus 11 months, respectively; HR 0.89, 95% CI 0.61–1.30); 64% of patients receiving DTIC crossed over to pimasertib. Serious adverse events (AEs) were more frequent for pimasertib (57%) than DTIC (20%). The most common treatment-emergent AEs were diarrhea (82%) and blood creatine phosphokinase (CPK) increase (68%) for pimasertib, and nausea (41%) and fatigue (38%) for DTIC. Most frequent grade ≥3 AEs were CPK increase (34%) for pimasertib and neutropenia (15%) for DTIC. Mean QoL scores (baseline and last assessment) were similar between treatments. Pimasertib has activity in NRAS-mutated cutaneous melanoma and a safety profile consistent with known toxicities of MEK inhibitors. Trial registration: ClinicalTrials.gov, NCT01693068.

7061 Background: Amrubicin, a totally synthetic 9-amino-anthracycline, has been shown to have excellent antitumor activity as a single agent against previously untreated extensive-stage SCLC. The objective of this study was to assess the efficacy and safety of amrubicin in patients with refractory or relapsed SCLC. Methods: Patients with histologically or cytologically confirmed SCLC, 20 to 74 years in age, performance status 0–2, with a history of receiving first- or second- line chemotherapy were eligible for the study. Amrubicin (45mg/m2/day) was administered on Days 1–3 every 3 weeks for four to six courses. The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 33 patients (Simon’s two-stage minimax design). Results: From June 2003 to January 2005, 35 patients (26 males/9 females, median age, 64 years) were enrolled, and 34 of these patients were treated with the study drug. Four courses or more were administered in 59% (20/34) of the patients, and dose reduction was required in 52% (15/29) of the patients who had received 2 courses or more. Four complete responses and 14 partial responses were observed among the 34 treated patients, yielding a RR of 53% (95% confidence interval: 35.1%–70.2%). The median survival duration in the patients was 8.8 months, and the 1-year survival rate was 26%. Grade 3/4 leukopenia, neutropenia, and thrombocytopenia were observed in 76%, 97% and 38% of the patients, respectively. Febrile neutoropenia occurred in 12 patients (35%), and one patient died from treatment related pneumonia. Conclusion: Amrubicin (45mg/m2/day) was effective in patients with previously treated advanced SCLC, however, severe hematological toxicities occurred in some patients.

4093 Background: The results of phase I portion of the treatment with the oral S-1 (a new oral fluoropyrimidine) plus oral leucovorin (LV) in patients (pts) with untreated metastatic colorectal cancer (mCRC) was reported at ESMO 2006. Dose limiting toxicities (DLTs) were grade 3 stomatitis/pharyngitis, nausea, diarrhea, ileus and exanthema. The recommended doses (RDs) for this phase II portion were determined to be S-1 40 mg/m2 and LV 25 mg/body orally given twice daily on days 1 to 14 of a 28-day cycle. The PK profiles of S-1 plus LV were similar to those of S-1 monotherapy and UFT plus LV, respectively. The main purpose of this phase II portion is to evaluate the efficacy and safety of S-1 plus LV at RD level in pts with untreated mCRC. Methods: Pts were eligible as follows; unresectable mCRC with no prior chemotherapy or receiving adjuvant chemotherapy completed at least 6 months before, histologically proven adenocarcinoma, PS(ECOG) 0–2, age 20 to 75, measurable lesions, adequate organ function and written informed consent. The pts received 40 mg/m2 of S-1 plus 25 mg/body of LV twice daily as RD in this phase II portion. The primary endpoint was the objective response rates (RRs), and secondary endpoints were time to progression (TTP) and toxicities. Results: Between Sep 2004 and Jun 2006, 56 pts of 65 enrolled pts received the treatment at RD level. The objective RRs were 55% (36 of 65) for all pts and 55% (31 of 56) for pts at RD. Disease control rates (DCRs) were 86% (56 of 65) for all pts and 86% (48 of 56) for pts at RD. Median TTP was 5.5 months for pts at RD, with a median follow-up of 5.5 months. The median survival time is under observation. During the 6 months from starting the treatment, the most common grade 3/4 toxicities at RD were as follows: diarrhea, 23%; stomatitis, 20%; anorexia, 18%; and neutropenia 13%. Conclusions: A combination of S-1 plus oral LV is an effective, well tolerated, and convenient regimen in pts with untreated mCRC, without the addition of either oxaliplatin or irinotecan. The updated results of the objective RRs, DCRs, TTP reviewed extramurally, and detailed safety profile will be presented at the meeting.
