4043 Background: Systemic treatment options for progressive metastatic NET, including islet cell carcinoma (ICC) and carcinoid tumor (CT), are limited. These tumors frequently express the epidermal growth factor receptor (EGFR). Gefitinib, a small-molecule inhibitor of the EGFR tyrosine kinase, has been shown to inhibit the growth of NET cell lines. Methods: Eligibility criteria included: radiographic progression by RECIST criteria, ECOG PS ≤ 2, ≤ 1 prior chemotherapy, and good organ function. Prior interferon and prior or concurrent octreotide (if disease progression documented on stable dose) were allowed. Pts received gefitinib 250 mg po daily. We evaluated 6 month (mos) progression-free survival (PFS) in two cohorts (ie, CT and ICC) using separate 2-stage phase II designs. 6 mos PFS rates of 30% (CT) and 10% (ICC) were considered promising. Results: 96 pts were enrolled: (57 CT, 39 ICC). For pts evaluable for the primary endpoint, 23 of 38 (61%) CT pts and 9 of 29 (31%) pts with ICC were progression-free at 6 mos. 1 PR and one minor response (MR = 20–29% decrease in sum of target lesion diameters) were observed in 40 CT pts; 2 PR and 1 MR in 31 ICC pts. In addition, 32% (12/38) of CT and 14% (4/29) of ICC pts had stable disease on study for a duration that exceeded by at least 4 months the time to progression documented prior to study entry. Grade 3–4 toxicity was infrequent with fatigue (6%), diarrhea (5%) and rash (3%) most common. Evaluation of markers of the EGFR pathway on tumor tissue will be presented. Conclusions: Gefitinib is well-tolerated and results in prolonged disease stabilization in pts with prior documented objective progression of CT and ICC, with rare objective responses.

4504 Background: Treatment options for metastatic NET, including islet cell carcinoma (ICC) and carcinoid tumor (CT), are limited. These tumors frequently express vascular endothelial growth factor receptor-2 (VEGFR-2) and platelet derived growth factor receptor receptor-β (PDGFR-β). Sorafenib, a small-molecule inhibitor of the VEGFR-2 and PDGFR-β tyrosine kinase domains, is a rational targeted therapy to evaluate in NET. Methods: Eligibility criteria included: ECOG PS = 2, = 1 prior chemotherapy, good organ function and signed informed consent. Prior interferon and prior or concurrent octreotide at a stable dose were allowed. Pts unable to take oral medications, with uncontrolled hypertension or with symptomatic coronary artery disease were excluded. Pts received sorafenib 400 mg po BID. Primary endpoint was response by RECIST in two cohorts (ie, CT and ICC) using separate 2-stage phase II designs. Results: 93 pts were enrolled: (50 CT, 43 ICC). For pts evaluable for the primary endpoint, 4 of 41 (10%) CT pts and 4 of 41 (10%) ICC pts had a PR. There were 3 minor responses (MR = 20–29% decrease in sum of target lesion diameters) in CT pts and 9 MRs in ICC pts for PR+MR rate of 17% for CT pts and 32% for ICC pts. For pts evaluable, 6-month progression-free survival was observed in 8/20 CT and 14/23 ICC pts. Grade 3–4 toxicity occurred in 43% of pts, with skin (20%), GI (7%) and fatigue (9%) most common. Translational studies from tumor tissue will be presented. Conclusions: Sorafenib at 400 mg po BID has modest activity in metastatic neuroendocrine tumors, with frequent grade = 3 toxicity.

616 Background: Sarcomatoid renal cell carcinoma (SRCC) is a rare but very aggressive type of RCC. The treatment option for SRCC is very limited, and there have been anecdotal reports of very good responders to gemcitabine or vascular endothelial growth factor receptor tyrosine kinaase inhibitors (VEGFR TKI). We conducted multicenter phase 2 trial of gemcitabine plus axitinib (GX) in patients (pts) with recurrent or metastatic SRCC to evaluate its efficacy and safety. Methods: Eligibility criteria included histologically confirmed metastatic or recurrent RCC with sarcomatoid component of 25% or more on resected kidney or exclusive sarcomatoid carcinoma on needle biopsy, ECOG PS 0-2, measurable lesion by RECIST v1.1, and adequate cardiac, hepatic, renal and bone marrow function. Pts with uncontrolled hypertension, prior exposure to gemcitabine or VEGFR TKI were exclude. Pts received gemcitabine 1,000 mg/m2 intravenously on days 1 and 8 by 3-week cycle and axitinib 5 mg twice daily. The primary endpoint was objective response rate (ORR) according to RECIST v1.1, and secondary end points were progression-free survival (PFS), overall survival (OS), and toxicity. Results: Twenty-five pts were enrolled between Oct 2014 and Aug 2018. Median age was 61 (range 33-80), and 84% was male. ECOG PS were 1 (92%) and 2 (8%), and 52% had prior nephrectomy. Clear cell carcinoma was the most common histology of carcinoma component, and median percentage of sarcomatoid component was 90% (25-100%). Pts belonged to intermediate (28%) and poor (72%) risk group according to IMDC risk stratification. Median 6 cycles of GX were administered, and 56%, 28%, and 12% of pts achieved PR, SD, and PD, respectively, with an ORR of 56% and median duration of response of 2.5 months. With a median follow-up duration of 21.4 mo, median PFS was 4.9 mo (95% CI, 3.5-13.3), and median OS was 8.4 months (95% CI 3.5-13.3 months). Most adverse events were manageable, and no unexpected toxicities were found. One pt died of grade 5 pneumonia. Conclusions: GX showed promising efficacy in pts with SRCC. GX might be considered as one of treatment options for pts with SRCC, although efficacy of GX should be confirmed in larger trial.

6042 Background: Epidermal growth factor receptor (EGFR) is commonly expressed in nasopharyngeal carcinoma (NPC) and strong EGFR expression appears to correlate with poor survival. Gefitinib, a small-molecule inhibitor of the EGFR tyrosine kinase, has been shown to inhibit the growth of NPC cell lines. Methods: Nineteen patients with recurrent or metastatic NPC were recruited into the study. Eligibility criteria included: radiographic progression of disease, ECOG PS < 2, 1 or more prior platinum-based chemotherapy regimens, normal organ function. Fifteen patients were treated for first relapse, 3 for second relapse, and 1 for third relapse. Local disease was present in 8, nodal disease in 3, and distant metastases in 14. All patients had previously received platinum-based chemotherapy as adjuvant and/or palliative treatments, and 89.5% had 2 or more regimens. Patients received gefitinib 250 mg po daily. Median treatment duration was 10 weeks and median follow-up time was 9 months. Results: Minor response was observed in 2 patients treated for advanced local recurrence. There were no complete or partial responders. Seven patients had stable disease and 12 had progressive disease. Median time to progression was 4 months and median survival was 14 months. Progression-free rate at 6 months was 22% and 1-year survival rate was 70%. Treatment was generally well tolerated and only grade 1–2 adverse events were observed, with acneiform rash (68.5%), fatigue (36.9%), diarrhea (31.6%), and anorexia (31.6%) most common. In 15 patients with symptoms related to NPC, 5 reported improvement, 5 reported no changes, and 5 reported worsening during gefitinib treatment. Conclusions: Gefitinib has little activity in terms of response rate in recurrent and metastatic NPC, although disease stabilization and symptomatic improvement were observed in some patients. Evaluation of markers of EGFR pathway on tumor tissue is currently being performed. No significant financial relationships to disclose.

2056 Background: GBM are the most common primary brain tumors in adults. Despite available treatment they carry a poor prognosis with recurrences in most patients (pts) after initial therapy. PDGF signaling has been postulated to play a role in GBM transformation. We have demonstrated that PDGFRβ is expressed in tumor cells in 50% and in peritumoral endothelial cells in 65% of GBM (Barrios et al, abstract 11518, Proc ASCO 2006). Imatinib, an inhibitor of PDGFRa/β kinase activity could have therapeutic activity in these cases. Methods: We evaluated Imatinib in pts with recurrent GBM (previous radiation and chemotherapy) selected by PDGFR expression. Analysis of PDGFRa/β was performed by standard IHC. Positivity was considered in case of any qualitative expression. Pts were treated with 800 mg/day of Imatinib until tumor progression. All were on steroids and taking enzyme inducing antiepileptic drugs. Response was determined by MRI with spectroscopy and perfusion every 8 weeks according to RECIST criteria. Results: Twenty pts were enrolled (18 GBM, 2 AA). Median age: 51 (21–74), 7 were females. ECOG-PS at inclusion: 0 (3), 1 (10), 2 (7). All pts had expression of PDGFRa and 55% expressed PDGFRβ. Response data are available for all 20 pts. Main adverse events (all grade 1–2) were: edema (55%), nausea (50%), diarrhea and fatigue (35% each). We did not observe any PR but 13 pts (65%) showed disease stabilization. Median progression-free survival was 7.8 months with 60.8% of pts alive at 6 months; 6 months PFS was 52.2%. Conclusions: Imatinib was well tolerated in this group of poor prognosis highly pre-treated GBM pts demonstrating disease stabilization in a significant proportion of cases. These results, in a limited sample, compare favorably with historical data in similar populations. Selection of pts according to the specific molecular expression of their tumor may lead to better therapeutic results. No significant financial relationships to disclose.

245 Background: Cholangiocarcinomas (CCK) are uncommon tumors with an increasing incidence and a poor prognosis. Epidermal growth factor receptor (EGFR) expression and activation in CCK have been demonstrated. Methods: We conducted a multicenter phase II trial combining cetuximab (Ctx), an anti-EGFR chimerized IgG1 monoclonal antibody, to gemcitabine (Gem). Patients with either locally advanced (LA) or metastatic (M) CCK (excluding gallbladder) were included; no prior systemic therapy was allowed. Ctx was administrated at the initial dose of 400 mg/m2 and further injections at 250 mg/m2 every 7 days, and Gem was administrated at 1000 mg/m2 on days 1, 8, and 15 every 4 weeks. The primary endpoint was the progression-free survival (PFS) rate at 6 months. A Simon 2-stage design was used. We hypothesized that Gem/Ctx would improve 6 month-PFS rate from 20% to 40%. We needed 3 patients with PFS ≥ 6 months from the first 13 to further include a total of 43 patients. Results: Forty-four patients with advanced CCK (41% LA/59%M) were enrolled from 09/2008 to 01/2010. Median age was 61.5 years (range 40-86) and baseline ECOG PS was 0 for 68% and 1 for 32% of the patients. Forty-three percent of the patients had prior surgery. Forty-six percent of the patients were free from progression at 6 months. Median PFS was 5.8 months (95% CI, 4.4-7.4 m) and median overall survival was 11.6 months (95% CI, 8.7-14.6 m). Nine patients (20.9%) had partial response with a median duration of 5 months (range 2-10 m). Disease control rate (PR + SD > 8 weeks) was 81.4%. The most common grades 3/4 related-toxicities were haematological abnormalities (47.7%), skin rash (13.6%) and fatigue (11.3%). Due to toxicity, 6 patients discontinued study treatment; 14 and 3 patients had a Gem and Ctx dose reduction respectively. Among the nine responders, 8 experienced a skin rash of at least grade 2, suggesting a relationship between skin toxicity and efficacy. Conclusions: Our study met its endpoint, i.e., a PFS rate of 46% at 6 months, suggesting that Gem-Ctx combination had promising activity with a manageable toxicity profile in advanced CCK. Adding Ctx to the new standard of care Gem-cisplatin deserves further investigations in CCK. [Table: see text]

488 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with 5-fluorouracil (5-FU), oxaliplatin and irinotecan. Methods: 34 pts were enrolled, with the following characteristics: 17 (50%) females, median age 57 years (28-72), 28 (82%) ECOG PS 0-1. S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was four (range 1-9). ORR was 14.7% (95% confidence interval [CI] 2.8-26.6) and disease control rate was 58.8% (95% CI 42.2-75.3) with five partial responses and fifteen stable diseases. Median duration of disease control was 5.1 months (95% CI 3.3-7.0). Median progression-free survival was 3.2 months (95% CI 2.3-4.1) and median overall survival was 11.8 months (95% CI 7.0-16.5). Grade 3-4 toxicities were neutropenia (12%), anemia (12%), thrombocytopenia (3%) and diarrhea (3%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was well tolerated and efficacious for heavily pre-treated mCRC pts, and could be an alternative for pts with good PS but no further treatment options.

588 Background: Now fluoropyrimidine plus Bmab is considered a recommendable option to the majority of elderly mCRC patients who are deemed inappropriate for the standard doublet chemotherapy with biologics. Our previous phase II study of UFT/ LV in elderly mCRC patients (≥75 years old) had demonstrated acceptable safety and efficacy (overall response rate [ORR] 33%, progression-free survival [PFS] 5.3 months, overall survival [OS] 18 months). The aim of the present study was to investigate the efficacy and safety of Bmab in combination with UFT/LV for elderly mCRC patients. Methods: This study was designed as a single-arm, open-label, multicenter, cooperative group (SGOSG-TCTG) clinical trial (trial registration: UMIN000003515). Key eligibility criteria included age ≥75 years, ECOG performance status (PS) 0 or 1, first-line chemotherapy, measurable lesions, and preserved organ functions. Patients received UFT 300mg/m2/day and LV 75mg/body/day on days 1-21 followed by 7 days rest, and intravenous administration of Bmab 5mg/kg on days 1 and 15. Treatment repeated every 28 days. The primary endpoint was PFS, and secondary endpoints were ORR, OS, and safety. Results: A total of 55 patients were enrolled from 15 institutions between Aug 2008 and Mar 2012. Among them, 52 eligible patients were evaluated. Median age was 80 years (range: 75-87). ECOG PS 0 was 73%. Median PFS was 8.2 months (95% confidence interval [CI], 6.2-10.3, events in 86.5%). Confirmed ORR was 40.4% (95% CI, 27.0-54.9%). Median OS was 18.7 months (95% CI, 10.3-27.0, events in 48%). The most common grade ≥3 treatment-related adverse events were hypertension (11.5%), fatigue (7.7%), nausea (5.8%), and diarrhea (5.8%). The treatment-related death occurred in 2 (3.8%) patients. Main reasons for discontinuation of treatment were disease-progression (62.5%) and toxicity (27.1%). Conclusions: Bmab in combination with UFT/LV is tolerable and effective treatment option for elderly patients (≥75 years old) with mCRC. Further trial with Bmab plus UFT/LV targeting elderly mCRC patients would be warranted. Clinical trial information: 000003515.

The Impact

574 Background: The SOL regimen (S-1, Oral Leucovorin; LV, and Oxaliplatin) demonstrated a promising activity with tolerated toxicities compared to mFOLFOX6 in a randomized phase II study for mCRC. We previously reported the promising results of a phase II study of SOL+BV in Gastrointestinal Cancers Symposium 2012 (Kato T, et al.) focusing on early clinical outcomes, overall response rate (ORR), progression free survival (PFS) and safety. The final follow-up (cut-off date Dec 2012) has been completed, and we report up-dated overall survival (OS) and the impact of early objective tumor response (EOTR) on OS in the present report. Methods: The main inclusion criteria were; (1) metastatic colorectal adenocarcinoma, (2) age ≥20 years, (3) no prior chemotherapy, (4) target lesion (RECIST v1.0), (5) ECOG PS 0-1, 6) written informed consent. Patients (pts) received S-1 (40-60 mg bid) and LV (25 mg bid) orally for one week. Oxaliplatin (85 mg/m2) and BV (5 mg/kg) were administered on day 1. This treatment was repeated every 2 weeks. The primary endpoint was ORR confirmed by the independent review committee according to RECIST v1.0. This trial was supported by Taiho Pharmaceutical CO, LTD. (JAPIC Clinical Trials information Identifier: JapicCTI-090881). Results: From Oct 2009 to Apr 2010, 31 pts were enrolled. Of the eligible 29 pts, median age was 62; PS 0/1 was 24/5; number of metastatic organs 1/≥2 was 15/14. ORR was 86% (95%CI, 68-96), and the median PFS was 15 months (95%CI, 10-26). OS has not reached median with a median follow-up time of 34 months. Two-year survival rate was 72%. EOTR (RECIST sum ≥30% shrinkage) at 6-weeks was observed in 35% of pts. Two-year survival rate in these pts with an EOTR at 6-weeks was 80%, while in other pts without an EOTR at 6-weeks was 68%. The curative resection rate of metastatic lesions was 28%. The incidence (≥10%) of grade 3/4 adverse drug reactions were; neutropenia 20%, hypertension 23%, anorexia 20%, fatigue 17%, diarrhea 10%, and sensory neuropathy 53%. Conclusions: The SOL+BV regimen showed the promising activity for mCRC. The high proportion of EOTR might lead to long survival. Further evaluation of this regimen would be warranted. Clinical trial information: 090881.

5558 Background: Various problems still exist in the management of recurrent ovarian cancer and there are limited treatment options especially for the platinum resistant patients (pts). We conducted a phase II study to evaluate the efficacy and safety of the combination irinotecan/oral etoposide chemotherapy. Methods: Eligibility criteria included recurrent ovarian cancer with measurable disease or positive CA125, preserved organ function, and aged 20–75. Treatment was conducted with irinotecan (60 mg/m2 iv, day 1, 15) and oral etoposide (50 mg/body day 1–21), q 28 days until disease progression or unacceptable toxicity. Primary endpoint was response rate (RR) and secondary endpoints included toxicity, progression-free survival (PFS), and overall survival (OS). Results: 38pts were enrolled on this study from May 2003 to April 2007, and all pts were eligible. Median age was 57 yrs (range 37–74). PS 0 in 24 pts, 1 in 10 pts, and 2 in 4 pts. Median number of previous regimen was 2 (range 1–4). Median treatment cycles were 6 (range 2–27). RR (CR+PR) was 18/38 (47.4%), and CR+PR+SD rate was 31/38 (81.6%). Grade 3/4 adverse effect included leukopenia (50.0%), neutropenia (52.6%), anemia (18.4%) and thrombocytopenia (2.6%), nausea/vomiting (7.9%) and diarrhea (2.6%). Treatment-related death was not observed. Median PFS was 7 months (range 1–33) and OS was 19 months (range 4–60). Among 20 pts with platinum resistant cases, RR was 6/20 (30.0%), CR+PR+SD rate was 14/20 (70.0%), median PFS was 6 months (range 1–33), and OS was 24 months (range 5–60). Conclusions: Combination irinotecan/oral etoposide chemotherapy can achieve a superior management for the recurrent ovarian cancer without declining QOL, and also has the possibility to be one of the most effective regimens as second-line chemotherapy.

5101 Background: The recently demonstrated activity of inhibitors of TORC1 in RCC has raised the possibility that even greater effects may be achieved by targeting upstream of this pathway. Perifosine is a synthetic alkylphospholipid which inhibits Akt activity and also has cell-dependent effects upon the MAP-kinase pathway. Prior single-agent trials showed disease stabilization/regression in patients (pts) with advanced RCC; however, few pts were previously treated with a TKI. Therefore, we conducted a multi-center phase II trial to determine the safety and efficacy of perifosine in pts with advanced RCC refractory to VEGFR TKI. Methods: Primary objectives were to measure the % of pts progression-free at 12 weeks (wks) and overall progression-free survival (PFS) of perifosine (100 mg qhs). Secondary objectives included overall response rate (> PR), and safety, Eligibility: ECOG PS 0–1, pts with metastatic RCC who have RECIST defined progression on either sunitinib or sorafenib. Prior Rx with immunotherapy and bevacizumab was permitted. Normal organ and marrow function required. Results: From 4/07–10/08, 24 pts were treated at four sites. Median age 67 (range 47–78) and 16 were male; 90% of pts had predominantly clear cell histology. Prior sunitinib = 12; prior sorafenib = 12 (1.5 avg prior Rx). As of 12/08, all 24 pts were evaluable for PFS, response and toxicity as follows in the table . 6/24 pts remain on treatment (range 7 - 84 wks). Therapy was well tolerated with primarily Grade (G) 1 & 2 adverse events. G 3 & 4 events were: dyspnea (8%), hyponatremia (8%), pulmonary embolism (4%) and arthalgia (4%). Conclusions: Perifosine has promising activity in pts with RCC who have failed prior TKI therapy. The favorable toxicity profile suggests potential for combinational therapies with VEGF-targeted agents. Additional studies are under consideration to evaluate perifosine for clinical benefit in pts with previously treated RCC. [Table: see text] [Table: see text]
