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.

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.

125 Background: AT-101 (A), a small molecule oral inhibitor of the Bcl-2 protein family has broad preclinical activity including synergy with docetaxel (D). AT-101 has demonstrated activity alone and in combination with D in D-refractory patients with metastatic CRPC. Methods: A randomized, double-blind, placebo-controlled phase II trial was conducted to compare the combination of DP with either A or placebo in chemo-naive men with progressive metastatic CRPC. A key requirement was progression (bone scan, RECIST or rising PSA ≥ 2 ng/mL) despite androgen deprivation. Stratification factors were pain and performance status. Patients received DP (75mg/m2 day 1; 5mg PO b.i.d.) Q 21 days (1 cycle) with either A (40 mg b.i.d.) or placebo PO on days 1–3. Radiological assessments were performed every 3 cycles. Primary endpoint was overall survival (OS) and 221 patients were planned for 110 events (80% power, HR 0.67, 1-sided alpha 0.1). Results: 221 patients were randomized to ADP or placebo-DP and baseline factors were balanced. Efficacy outcomes (OS, PFS, PSA declines, disease control) were not significantly different ( Table ). In a subgroup of patients with poor-risk CRPC (n=34), efficacy endpoints appeared to favor ADP with a median OS of 19 months vs.14 months for placebo-DP. Grade 3/4 AEs that occurred with higher incidence in the ADP arm compared to placebo-DP included cardiac AEs (5% vs. 2%), lymphopenia (23% vs. 16%), neutropenia (47% vs. 40%), ileus (2% vs. 0%) and pulmonary embolism (6% vs. 2%). Conclusions: The combination of AT-101 with DP in men with chemonaive metastatic CRPC was well tolerated but did not extend OS compared to placebo-DP. There was a potential benefit in a subset of high-risk patients. [Table: see text] [Table: see text]

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.

PURPOSE SARC024 is a phase II clinical trial of the multikinase inhibitor regorafenib in specific sarcoma subtypes, including advanced osteosarcoma. We hypothesized that regorafenib would improve progression-free survival (PFS) in patients with sarcoma and report the results of the osteosarcoma cohort. PATIENTS AND METHODS This trial enrolled patients with progressive metastatic osteosarcoma with measurable disease by RECIST who had received at least one prior line of therapy. Patients were randomly assigned at a ratio of one to one to regorafenib or placebo. Crossover was allowed at time of disease progression. PFS was the primary end point of the study, which was powered to detect a difference of at least 3 months in median PFS. RESULTS Forty-two patients from 12 centers were enrolled between September 2014 and May 2018. Median age was 37 years (range, 18 to 76 years). Patients had received an average of 2.3 prior therapy regimens. Ten patients receiving placebo crossed over to active drug at time of progression. Study enrollment was stopped early, after a data safety monitoring committee review. Median PFS was significantly improved with regorafenib versus placebo: 3.6 months (95% CI, 2.0 to 7.6 months) versus 1.7 months (95% CI, 1.2 to 1.8 months), respectively (hazard ratio, 0.42; 95% CI, 0.21 to 0.85; P = .017). In the context of the crossover design, there was no statistically significant difference in overall survival. Fourteen (64%) of 22 patients initially randomly assigned to regorafenib experienced grade 3 to 4 events attributed to treatment, including one grade 4 colonic perforation. CONCLUSION The study met its primary end point, demonstrating activity of regorafenib in patients with progressive metastatic osteosarcoma. No new safety signals were observed. Regorafenib should be considered a treatment option for patients with relapsed metastatic osteosarcoma.

PURPOSE Platinum-based therapy is the standard of care in patients who have HER2-negative, advanced esophagogastric cancer (AEGC). Retrospective data suggest that intratumoral ERCC1 levels may determine platinum sensitivity. A randomized, phase II study was performed in patients with AEGC to explore whether the efficacy of a platinum-based therapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) versus a non–platinum-containing regimen of irinotecan and docetaxel (IT) differed according to ERCC1 levels. PATIENTS AND METHODS Overall, 202 untreated patients with HER2-negative AEGC and a Zubrod performance status of 0-1 were evaluated prospectively for mRNA expression of ERCC1 level and then randomly assigned to FOLFOX or IT, stratified by the intratumoral statuses of ERCC1 low (< 1.7) or high (≥ 1.7). Objectives were to assess progression-free survival (PFS) and overall survival (OS) in all patients treated with FOLFOX compared with IT, stratified by low and high ERCC1 levels, and to assess for interactive effects between ERCC1 expression and treatment arm. RESULTS Eighty-six percent of patients had ERCC1 values < 1.7. Thus, evaluation of the ERCC1-high subgroup was limited. Grade ≥ 3 anemia, dehydration, diarrhea, and fatigue were greater in patients with IT. Occurrences of grade ≥ 3 neuropathy and decreased neutrophils were greater in patients with FOLFOX. In all patients, FOLFOX had a statistically superior median PFS compared with IT (5.7 v 2.9 months; hazard ratio, 0.68; P = .02). In patients with ERCC1 levels < 1.7 receiving FOLFOX, PFS and response rate were statistically superior to IT, with no significant difference in OS. CONCLUSION The evaluation of ERCC1 in patients with upper GI tumors was thwarted by an overwhelming predominance of low ERCC1 mRNA expression. Nonetheless, distribution of treatment effects on PFS did not vary with expression. For all patients and for those with low ERCC1 expression, FOLFOX was superior in efficacy to IT.

Abstract Background There is an urgent need for effective treatments against glioblastoma (GBM). In this trial we investigated the efficacy and safety of an adoptive cell-based immunotherapy. Methods Patients with newly diagnosed GBM were recruited at four study sites in Sweden. The patients were randomized 1:2 to receive either radiotherapy (RT), 60 Gy/30 fractions, with concomitant and adjuvant temozolomide (TMZ) only, or RT and TMZ with addition of Autologous Lymphoid Effector Cells Specific Against Tumor (ALECSAT) in an open-label phase II trial. Primary endpoint was investigator-assessed progression-free survival (PFS). Secondary endpoints were survival and safety of ALECSAT. Results Sixty-two patients were randomized to either RT and TMZ alone (n=22) or RT and TMZ with ALECSAT (n=40). Median age was 57 years (range 38-69), 95% of the patients were in good performance status (WHO 0-1). There was no significant difference between the study arms (SOC vs. ALECSAT + SOC) in PFS (7.9 vs. 7.8 months; HR 1.28; 95% CI 0.70, 2.36; P=0.42), or in median overall survival (OS) (18.3 vs. 19.2 months; HR 1.16, 95% CI 0.58, 2.31; P=0.67). The treatment groups were balanced in terms of serious adverse events (52.4% vs. 52.5%), but adverse events ≥ grade 3 were more common in the experimental arm (81.0% vs. 92.5%). Conclusion Addition of ALECSAT immunotherapy to standard treatment with radiochemotherapy was well tolerated but did not improve PFS or OS for patients with newly diagnosed GBM.

4138 Background: Everolimus (EVE) antitumor efficacy in patients (pts) with advanced NET was demonstrated in 2 double-blind, placebo (P)–controlled, phase III trials (RADIANT-2 and RADIANT-3). Median PFS in pancreatic (pNET) pts was 11.0 months (EVE) vs. 4.6 months (P) (HR 0.35, 95% CI 0.27-0.45, P <0.001) in RADIANT-3. Median EVE exposure in RADIANT-3 was 38 wks. EVE was approved for advanced pNET in the US and Europe in 2011. An expanded access protocol was launched to gather additional safety data and provide access to EVE for pts with advanced NET while awaiting regulatory approval. Methods: Pts aged ≥18 years with biopsy-proven NET; WHO performance status 0-2; and adequate bone, hepatic, and renal function were enrolled. Main exclusion criteria were poorly differentiated NET and cytotoxic therapy within 4 wks of enrollment. EVE (10 mg/d) was administered until disease progression, unacceptable toxicity, discontinuation, death, commercial availability of EVE, or until May 30, 2012. Pts were enrolled from April 21, 2011 to April 20, 2012. Primary objective was grade 3/4 and serious adverse events (AEs). Secondary objectives included investigator-assessed best overall response rate and PFS. Results: The full analysis set included 246 pts (pNET, n=126; non-pNET, n=120); the safety set included 240 pts (pNET, n=123; non-pNET, n=117). Median age was 61 and 66 years; 54% and 49% were male. Main primary tumor sites in non-pNET pts included small intestine (40%) and lung (22%). Median duration of EVE exposure was 12.1 wks and 24 wks in pNET and non-pNET. At data cutoff, there were 21 and 32 PFS events; 105 and 88 pts were censored. Grade 3/4 AEs were reported in 42.3% and 69.2% of pNET and non-pNET; those reported in ≥10% of pts in pNET and non-pNET included hyperglycemia (12.2% and 5.1%), diarrhea (10.6% and 31.6%), stomatitis (9.8% and 11.1%), nausea (8.1% and 10.3%), and anemia (5.7% and 11.1%). Median investigator-assessed PFS was 7.6 (95% CI 5.52-7.62) months and 10.8 (8.77-Not Estimable) months in pNET and non-pNET. Conclusions: EVE was well tolerated in pts with advanced NET. AEs were similar to those previously reported. Protocol-specified early termination of pts limits the interpretation of PFS medians. Clinical trial information: EudraCT Number: 2010-023032-17.

Abstract Abstract 4488 Src-family kinases (SFK) are described to be over expressed in CLL resulting in increased BCR signaling. Aberrant activation of the SFK, Lyn, leads to defective apoptosis of CLL cells in-vitro. C-Abl kinase is also overexpressed in CLL cells compared to normal B-lymphocytes. Since dasatinib is a dual Src and c-abl kinase inhibitor with in-vitro pro-apoptotic properties in CLL cells, we investigated the activity of dasatinib in patients (pts) with CLL. We designed a phase II study of dasatinib in pts with relapsed CLL/SLL and T-PLL. Pts were eligible if they were previously treated and had indication for therapy according to NCI-working group criteria. All pts had adequate performance status, renal and liver function prior to therapy. Treatment consisted of dasatinib 50mg given orally twice daily. In case of suboptimal response the dose of dasatinib could be increased up to a maximum dose of 70mg twice daily. Dose reductions to 20mg twice daily were permitted for toxicity. Pts were assessed for treatment response according to 1996 NCI-WG criteria. Seventeen pts have been enrolled in this study. The median age was 67 years (42-83 years), 9 (52%) had Rai stage III-IV, median beta-2 microglobulin levels was 5.9 (3.0 – 11.8) mg/L. The median number of prior treatments was 4 (1 – 8). An objective response (PR) was observed in 1 patient, 13 pts had no objective response and 3 pts were not evaluable for response due to early discontinuation of therapy (0-3 days). Fourteen pts remained on therapy for a median of 2 (0-19) months with 4 pts discontinuing due to disease progression and 9 pts discontinuing due to adverse events and lack of response. Hematological toxicities consisted of grade 3–4 neutropenia in 76% of the pts, grade 3–4 thrombocytopenia in 44% of pts and grade 1–2 anemia in 80%. Non-hematological toxicity consisted of grade 3–4 fatigue in 1 patient and grade 3 pleural effusions in another patient. Grade 1 and 2, toxicities included flushing 38%, headache 38%, fatigue 46% anorexia and nausea 46%, and diarrhea 23%. Several pts showed evidence of biological activity. Treatment with dasatinib lacks efficacy in pts with heavily pretreated CLL. Responses occurred in only 6% of pts and dasatinib administration was associated with a high incidence of neutropenia.

1012 Background: SRC family kinases (SFK) mediate numerous signal-transduction pathways relevant to breast cancer as well as osteoclast function. Dasatinib, a potent oral inhibitor of SFK and other kinases has preclinical activity in breast models and in vitro synergy with Cap in some breast cancer cell lines (KPL-4 and HCC-70). A phase I trial of dasatinib plus Cap was conducted to define dose-limiting toxicities (DLT), maximum tolerated (MTD), and recommended phase II (RP2D) doses. Methods: Sequential cohorts of pts with ABC were treated with Cap twice daily (BID) on days 1–14 and dasatinib daily in 21-day cycles using dose levels (DL) for Cap (mg/m2) and dasatinib (mg): DL1: Cap 825 + dasatinib 50 BID; DL2: Cap 825 + dasatinib 70 BID; DL3: Cap 1000 + dasatinib 70 BID; DL3a: Cap 1000 + dasatinib 100 once daily (QD). All pts had ECOG performance status 0–1, had prior anthracycline and/or taxane, and received ≤2 regimens in advanced setting. MTD was based on DLT in first cycle and RP2D also based on tolerability of additional cycles. Results: 31 pts with ABC, median age 53 years (range 36–78) were treated. Number of pts treated/evaluable for DLT/reported DLT (event) were DL1: 7/6/1 (headache, grade 3); DL2: 9/7/0; DL3: 6/6/1 (diarrhea, grade 3), and DL3a: 9/9/1 (pneumonia, grade 3). Most frequent AEs related to either drug and occurring at any time on study (n pts) were nausea (12), vomiting (7), diarrhea (6), abdominal pain (2), fatigue (8), headache (7), musculoskeletal pain (1), and pleural effusion (4); hand-foot syndrome (5) was as expected for Cap alone. 11 patients experienced a Grade 3–4 non-hematologic AE at some point during the study. Laboratory abnormalities were uncommon. To date, 20 pts have continued treatment for ≥6 weeks and 9 pts for ≥12 weeks. Number of pts who (at any time) reduced dasatinib/reduced Cap/discontinued for toxicity were DL1: 2/2/1; DL2 2/2/3; DL3: 2/1/2; DL3a: 0/1/1. Updated safety and efficacy data will be presented. Conclusions: Dasatinib + Cap was tolerated without unexpected combined-treatment toxicity; few pts required dose reduction in later cycles. The recommended phase II dose, Cap 1000 plus dasatinib 100 QD, is well tolerated and will be studied for efficacy in an expanded patient cohort. [Table: see text]

14101 Background: The combination of 5-FU and CDDP has been reported to be active against metastatic gastric cancer (MGC), and great synergy has been shown in vivo and in vitro when 5-FU precedes CDDP. We investigated a sequential combination of S-1 (Tegafur, oxonic acid, CDHP) followed by CDDP for MGC. Methods: In order to determine a maximum tolerated dose (MTD) and recommended phase II dose (RD), we conducted a phase I trial applying increasing doses of oral administration of S-1 (65–80mg/m2) for 21 days and increasing doses of CDDP (60–80mg/m2) on day 22 every 35 days. Pts with metastatic or recurrent gastric cancer, no prior chemotherapy, measurable disease, performance status ECOG less than 3, and adequate organ functions were eligible for the study. Three pts were treated at each dose level with escalation based on toxicity. Fifteen pts were included and evaluated for DLT and MTD. Results: DLT was NCICTC grade 3 anorexia and fatigue in patients treated at the dose level 5 of S-1 80mg/m2 and CDDP 80mg/m2. Other toxicity more than grade 3 was neutropenia (grade 3) and nausea/vomiting (grade 3). Non-hematological toxicities were grade 1/2 and included diarrhea, nausea and stomatitis. There was no treatment-related mortality. The recommended dose was a combination of S-1 80mg/m2 and CDDP 70mg/m2. A tentative median survival was 19.5 months. Conclusions: This sequential S-1 and CDDP administered every 35 days is tolerable and beneficial for patients with MGC, and thus the consequent phase II trial is recommended. A multicenter phase II study is currently under way. No significant financial relationships to disclose.
