4043 Background: A Phase I/II trial evaluated single and repeated cycles of fractionated radioimmunotherapy (RAIT) with 90Y-labeled humanized mAb (90Y-hPAM4) plus Gem as first-line therapy in Stage 3-4 APC. Methods: Cycles of Gem once-weekly x 4 with 90Y-hPAM4 on wks 2, 3 and 4 were repeated until progression, withdrawal or unacceptable toxicity. In Part I, 90Y doses were escalated with Gem fixed at 200 mg/m2. In Part II, Gem was increased up to 1000 mg/m2, with 90Y fixed at 12 mCi/m2 for cycle 1 and lowered for retreatment. Results: Of 100 pts entered, 10 withdrew early, while 90 (73 stage IV) received 1-4 cycles. In Part I, 38 pts received 90Y-hPAM4 weekly x 3 at 6.5, 9, 12, or 15 mCi/m2, with the same cycle repeated 1-3 times in 13 pts. By CT-RECIST criteria, 6 pts (16%) had PRs and 16 (42%) had stabilization as best response (58% disease control). After cycle 1, 52% (13/25) with PET-avid images had >25% SUV reduction, and 33% (9/27) with elevated CA19-9 levels decreased by >50%. The median OS was 7.7 mo., but 11.8 mo. for retreated pts [46% (6/13) survived ≥1 yr.], and with improved efficacy at higher 90Y doses. NCI-CTCv3 Grade 3-4 platelets or ANC developed in 20/38 (53%) after cycle 1 (all reversible to Grade 1) and in all retreated pts (irreversible in 4/9 pts at 12 or 15 mCi/m2). In Part II, 52 pts received increased Gem without evidence of improved efficacy, while 13 pts were retreated with more acceptable toxicity at lower 90Y doses of 6.5 or 9 mCi/m2. Treatment was well tolerated with no infusion reactions. Infections requiring IV antibiotics occurred at a low rate and responded to appropriate coverage (bacteremia/sepsis, 7%; febrile neutropenia, 4%; ascending cholangitis, 3%; pneumonia, 2%; others 1%). One case of bleeding occurred, due to rectal tumor invasion. Anecdotal reports of good performance and decreased pain medication requirements require further validation. Conclusions: Fractionated RAIT with 90Y-hPAM4 combined with low-dose 200 mg/m2 GEM appears promising as a treatment regimen for APC. Hematologic toxicity was dose limiting. A 90Y-hPAM4 dose of 12 mCi/m2 for cycle 1 and 6.5 mCi/m2 for cycle 2 have been selected as suitable for further clinical development in the first-line setting.

227 Background: A Phase I/II trial was undertaken to evaluate repeated cycles of 90Y-labeled anti-mucin humanized mAb (90Y-hPAM4) plus Gem as first-line therapy in Stage 3-4 APC. Methods: Pts received Gem once-weekly x 4 with 90Y-hPAM4 on wks 2, 3 and 4, with cycles repeated until progression or unacceptable toxicity. In Part I, pts were treated in cohorts with escalating 90Y doses and Gem fixed at a low 200 mg/m2 dose for radiosensitization. In Part II, the Gem doses were increased up to standard levels, with 90Y doses fixed for first cycle, but decreased for subsequent cycles. Tumor responses were assessed by CT, FDG/PET and serum CA19-9; safety by NCI-CTCv3. Results: Of 100 untreated pts enrolled, 10 withdrew early, while 90 (73 stage IV) received 1-4 cycles. In Part I, 38 pts received 90Y-hPAM4 weekly x 3 at 90Y doses of 6.5 (N=4), 9 (N=12), 12 (N=17) or 15 (N=5) mCi/m2, with the same cycle repeated 1-3 times in 13 pts. Grade 3-4 platelets or ANC developed in 20/38 (53%) after cycle 1 (all reversible to Grade 1) and in all retreated pts (irreversible in 4/9 pts at 12 or 15 mCi/m2). There were 3 febrile neutropenias, 4 other infections treated with IV antibiotics, but no major bleeding or other AEs. By CT-RECIST criteria, 6 pts (16%) had PRs and 16 (42%) had stabilization as best response (58% disease control). After cycle 1, 52% (13/25) with PET-avid images became negative or had >25% SUV reduction, and 33% (9/27) with elevated CA19-9 levels decreased by >50%. The median overall survival was 7.7 mo., but 11.8 mo. for retreated pts [46% (6/13) survived ≥1 yr.], with improved efficacy at higher 90Y doses. In Part II, 52 pts received 12 mCi/m2 90Y-hPAM4 x 3 with Gem doses of 200 (N=17), 600 (N=8) or 1000 mg/m2 (N=27), with 13 pts now retreated at 90Y doses of 6.5 or 9 mCi/m2. Results so far indicate no advantage to giving higher doses of Gem with RAIT. Toxicity, response and survival data for this group will be presented at the conference. Conclusions: Fractionated RAIT with 90Y-hPAM4 combined with low-dose gemcitabine appears to be a manageable and active first-line therapy for APC. It may provide comparable efficacy yet less toxicity compared to other regimens.

e18033 Background: Endostar is a recombinant human endostatin. We conducted a multi-centre trial to investigate the efficacy and safety of Endostar plus GP with maintenance Endostar as first- line therapy for advanced NSCLC Methods: Chemotherapy-naïve patients with histologically or cytologically confirmed, measurable, stage ‡W NSCLC were enrolled from 11 centers in China. All patients received gemcitabine 1,000 mg/m2 (days 1 and 8) plus cisplatin 25 mg/m2 (days 1-3) every 21 days. Patients achieving objective response or disease stabilization following initial 2 cycles of GP were given Endostar (15 mg) on days 1–14 every 21 days in combination with another 2 cycles of GP. Then, patients who did not progress received maintenance endostar (15 mg) on days 1–14 every 21 days until disease progression or unacceptable toxicity. The primary was progression-free survival (PFS). Secondary endpoints were treatment-related toxicity and median overall survival (OS). Results: Between Oct.2008 and Sep. 2010, we enrolled 85 patients (median age: 52.2 years; median KPS score: 80; stage IV with M1b: 94.1%; adenocarcinoma: 64.6%). 48 (56.5%) patients complete 4 cycles of GP plus 2 cycles of Endostar and 33(38.8%) patients were treated with maintenance Endostar. For 38 patients receiving maintenance therapy, median PFS throughout the study period by independent review was 5.97 month and 1-year survival rate was 75.8%. Median PFS were 3.97 months for all 85 patients, while 1-year survival rate was 64.7%. No treatment related death occurred. 28(32.9%) patients had at least one grade 3/4 adverse events; the grade 3/4 hematologic toxicity included anemia in 32.9%, thrombocytopenia in 25.9%, neutropenia in 4.7% of patients. The grade 3/4 non-hematologic toxicities included nausea/vomiting in 18.8%, rash in 5.9%, hepatic impairment in 3.5%, diarrhea in 1.2%, hemorrhage in 1.2% of patients. Conclusions: This regimen, involving maintenance Endostar, didn’t significantly improve PFS in advanced NSCLC patients as compared to historic control although associated acceptable toxicity has been demonstrated

BackgroundOsimertinib is an effective first-line therapy option for EGFR-mutant NSCLC, but virtually all patients develop resistance. CRIPTO, through Src activation, has been implicated in resistance to EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy. Dasatinib, a Src inhibitor, has shown preclinical synergy with EGFR-TKI therapy.MethodThis is a single-arm phase I/II trial of osimertinib and dasatinib in TKI-naïve advanced EGFR-mutant NSCLC (NCT02954523). A 3 + 3 design was used in the phase I to establish the recommended phase II dose (RP2D). Osimertinib 80 mg QD was combined with dasatinib 70 mg BID (DL2), 50 mg BID (DL1), 70 mg QD (DL-1), and 50 mg QD (DL-2).ResultsTen patients (DL2: 3, DL1: 6, DL -1: 1) were enrolled. 3 (50%) of 6 patients at DL1 experienced a DLT (grade 3 headaches/body pain, neutropenia, rash, one each). Common treatment-related adverse events included pleural effusion (n=10), diarrhea (n=8), rash (n=7), transaminitis (n=7), thrombocytopenia (n=7), and neutropenia (n=7). While the MTD was not determined by protocol-defined DLT criteria, DL-2 was chosen as the RP2D, considering overall tolerability. Nine (90%) patients had a PR, including 1 unconfirmed PR. Median PFS was 19.4 months and median OS 36.1 months. The trial was closed to accrual prematurely due to slow accrual after the approval of osimertinib as first-line therapy.ConclusionsThe combination of dasatinib and osimertinib demonstrated anticancer activity. The treatment was limited by chronic toxicities mainly attributed to dasatinib. To improve the safety and tolerability of Src and EGFR co-inhibition, Src inhibitors with a more favorable safety profile should be utilized in future studies.Clinical Trial Registrationhttps://clinicaltrials.gov/ct2/show/NCT02954523

Abstract Objectives: To evaluate the efficacy and toxicity of a response-adapted therapy with rituximab/bendamustine/mitoxantrone/dexamethasone (RBMD), followed by rituximab (R) maintenance therapy in patients with relapsed or refractory follicular lymphoma (R/R FL) to first-line treatment with R-chemotherapy (R-ChemoT). Material and methods: Multicenter phase II trial including 60 patients with R/R FL, after a first R-ChemoT line. Induction therapy: R 375 mg/m2 IV, day 1; bendamustine 90 mg/m2 IV, days 1 and 2; mitoxantrone 6 mg/m2 IV, day 1; dexamethasone 20 mg/day, PO, days 1 to 5. Cycles of 28 days. Evaluation of response after third cycle. If stable (SD) or progression disease (PD): patient withdrawn from the study. If complete response (CR) or unconfirmed complete response (CRu): administration of fourth cycle. If partial response (PR): administration up to 6 cycles. If CR, CRu, or PR after induction: patient received maintenance therapy with R (375 mg/m2/day every 12 weeks for 2 years). Results: N=60 patients: 50% female, age 63 (32-76) years. Ann Arbor stage III-IV 70% (42/60). FLIPI intermediate-high risk: 50% (30/60). Refractory to R-ChemoT: 18% (11/60). Received RCHOP as first line therapy: 77% (43/60). R maintenance after first line therapy: 43% (26/60). Number of administered RBMD cycles: 4 (1-6). Efectiveness: CR/CRu after 3 cycles (CR-3), 27 patients. Response after induction therapy (4-6 cycles): Overall response (OR), 88.5% (53/60); CR, 58.5% (35/60); CRu, 12% (7/60); PR, 18% (11/60); SD, 1.5% (1/60); PD, 10% (6/60). Median follow-up: 24.41 mo. (15.58-30.15). Progression free survival, median not reached (NR) (28.28-NR). Overall survival, median NR (NR-NR). OR after RBMD in patients who received R maintenance after first line therapy, 96% (25/26; CR + CRu, 65%). OR in patients who did not receive R maintenance after first line therapy, 94% (32/34; CR + CRu, 82%). Safety: Grade 3/4 hematologic toxicity: neutropenia, 60% (n=36; 34 patients received G-CSF); anemia, 2% (n=1); thrombopenia, 4% (n=2). Grade 3/4 infections: 8% (n=4); febrile neutropenia 8%, (n=4). Exitus, 2/60 (PD, cycle 1; influenza A, cycle 5). Grade 3/4 non-hematologic toxicity: infusion reaction, 4% (n=2). No skin reactions. Patient withdrawals before R maintenance therapy: no inclusion criteria (NIC), 2/60; protocol delay of over 4 weeks, 7/60. Forty-four patients began R maintenance therapy (CR-3, 24/44). During R maintenance therapy: PD, 8/44 (18%; 5/8 in CR-3 patients); SD, 1/44 (2.5%); NIC, 3/44 (7%, all CR); protocol delay, 1/44 (2.5%); toxicity, 1/44 (2.5%, myelodysplastic syndrome). Response to R maintenance therapy: OR, 68% (30/44); CR, 61% (27/44; in CR-3 patients, 65%, 17/26); CRu, 4.5% (2/44); PR, 2.5% (1/44). Conclusions: RBMD is an effective and safe alternative for patients with R/R FL who have received first line treatment with R-ChemoT and R maintenance therapy. This response-adapted treatment strategy achieved results similar to the scheme with 6 cycles and may allow reduction of the intensity and duration of induction therapy and minimize toxicity. No skin reactions were reported, possibly due to the inclusion of dexamethasone in the treatment scheme. Disclosures No relevant conflicts of interest to declare.

PURPOSE Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer death worldwide. Platinum agents and fluoropyrimidines are the main compounds used in the first-line setting for advanced GC. Given the activity of fluorouracil (FU) bolus, the PFL protocol, a chemotherapy regimen combining cisplatin, FU bolus, and leucovorin, was incorporated at the Brazilian National Cancer Institute, because this schedule does not require hospitalization or infusion pumps. This study aims to evaluate the outcomes of PFL in the first-line setting for patients with advanced GC. MATERIALS AND METHODS This was a retrospective cohort study evaluating patients with advanced GC treated in the first-line setting with cisplatin 80 mg/m2 on day 1 and FU bolus 400 mg/m2 plus leucovorin 20 mg/m2 on days 1, 8, 15, and 22 every 4 weeks, from January 2008 to December 2014. RESULTS A total of 109 patients were enrolled. The median number of cycles received per patient was four (one to 11). Complete responses were achieved in 6.4% and partial responses in 14.7%. Median progression-free survival was 6.3 months (95% CI, 5.08 to 7.58 months) and median overall survival was 8.3 months (95% CI, 6.79 to 9.87 months). Thirty-four (31.2%) patients were alive in 1 year. Grade 3 and 4 adverse events were experienced by 26.6% and 3.7% of patients, respectively, with dose reduction necessary in 9.1%. CONCLUSION PFL is active in advanced GC and could be an alternative for FU continuous infusion protocols in institutions with limited resources and/or low budget, which is the reality in many nations all over the world.

The aim of this study was to evaluate the activity and toxicity of a tirapazamine (TPZ)/cisplatin drug combination in patients with stage IV or recurrent cervical cancer. The chemotherapy was administered for a maximum of eight cycles every 21 days. TPZ was administered intravenously at 330 mg/m2 over a 2-h infusion, followed 1 h later by cisplatin intravenously at 75 mg/m2 over 1 h on day 1. All patients received antiemetics including dexamethasone, ondansetron, and lorazepam. Subsequent doses were unchanged, reduced, or omitted according to observed toxicity and protocol guidelines. Response evaluation was performed every two cycles. Thirty-six patients with stage IV or recurrent cervical cancer were treated. Ninety-four percent of patients had prior radiotherapy. Two patients had prior chemotherapy. There were two complete responses and eight partial responses (27.8%). An additional 11 patients (30.6%) had stable disease as their best response. Response rate was greater in tumors outside of the previously radiated field (44.4% vs 11.1%). The median time to progression was 32.7 weeks. The most frequent grade 3 or 4 adverse events were nausea, vomiting, and fatigue, which occurred in 30.6%, 25%, and 22% of subjects, respectively. Anemia was the most frequent grade 3 or 4 hematologic toxicity at 8.3%. We conclude that the combination of cisplatin and TPZ was reasonably well tolerated in patients with recurrent or advanced cervical cancer. Further evaluation of this drug combination may be warranted.

221 Background: PCI-27483 is a selective inhibitor of FVIIa, a serine protease activated by interaction with tissue factor (TF). TF upregulation in tumor cells correlates with angiogenesis and a worsened prognosis. Hydrolysis of protease activated receptors by the TF:FVIIa complex induces up-regulation of IL-8 and VEGF. PCI-27483 inhibited the growth of human pancreatic tumors in animal models at a 2.5x to 3.0x change in prothrombin time. PK/INR relationships from a phase I study in healthy volunteers were used to select initial doses of PCI-27483 for the current study. Methods: Patients (pts) with locally advanced or metastatic pancreatic cancer, ECOG performance status 0-1, and normal coagulation were enrolled. All pts in phase I and II receive gemcitabine (G) as a 30-min IV infusion at a dose of 1000 mg/m2 on 3 out of every 4 wks. PCI-27483 is administered twice daily by SC injection. In phase I, doses of PCI-27483 were intra-patient escalated (0.8 to1.2 to1.5 mg/kg) over 4 to 8 wks. The targeted peak INR, measured 2 h postdose, was 3.0. In phase II, pts are being randomized to a control arm to receive G only or to a PCI-27483 arm to receive G plus PCI-27483. Phase I pts receiving 80% of planned doses during in first 6 wks were considered evaluable. Spiral CT scans are performed at 8-wk intervals. Study endpoints: adverse event profile, progression-free survival, venous thromboembolic events, and overall survival. Results: Phase I—8 pts enrolled, 5 pts evaluable. Highest dose of PCI- 27483 achieved was 0.8 mg/kg for 2 pts, 1.2 mg/kg for 3 pts and 1.5 mg/kg for 3 pts. Hematologic toxicity: grade 3 neutropenia (n= 1) or anemia (n = 2). Other grade 3 toxicities: elevated INR (n = 4) or elevated aPTT (n = 1). Dose-level-specific mean 2-h INR values were 2.2 at 0.8 mg/kg (CV=9%; n=7), 3.2 at 1.2 mg/kg (CV=33%; n=6) and 2.9 at 1.5 mg/kg (CV=16%; n=3). No VTEs occurred. Radiologic evaluations of 5 evaluable pts: 4 SD at 16 wks (1st pt SD for >40 wks; 5th pt SD at 8 wks, 16-wk scan pending). Conclusions: PCI-27483 is well tolerated at doses up to 1.5 mg/kg bid with G 1,000 mg/m2. Sustained SDs occurred and INRs were generally within the expected range. The randomized phase II study is ongoing at a dose of 1.2 mg/kg bid. [Table: see text]
