3085 Background: Hydroxychloroquine (HCQ) is an inducer of the tumor suppressor Par-4 (prostate apoptosis response-4) secretion from normal cells. Secreted Par-4 causes paracrine apoptosis of tumor cells in mice. Established dosing of HCQ 200 mg bid induces Par-4 secretion but not the autophagy-inhibition marker p62 and correlates with apoptosis induction in patients' tumors. Methods: This is a single-arm, single institute phase II study to characterize the biological effects of 3-months of HCQ at fixed-dose (200 mg p.o. twice a day) on plasma Par-4 levels in adults with resected solid tumors. The primary endpoint is proportion of patients who will exhibit a two-fold increase in Par-4 levels from baseline compared to 3 months of follow-up. 12-month progression free survival (PFS) is one of the secondary endpoints. A Simon's two-stage design was used to test the null hypothesis that the proportion of patients exhibiting a two-fold increase in Par-4 is equal to 50% compared to 70% using a one-sided alternative. These hypothesized assumptions are based on a small pilot human data and from a phase I clinical trial on a small number of patients (n = 9). The first stage of interim analysis will be performed after a total of 15 patients have been accrued. If there are eight or fewer responses occurred, the study will be stopped. Otherwise, 28 additional patients will be accrued for a total of 43 subjects. Results: A total of 19 patients were enrolled in the trial. Per protocol, the interim analysis and stopping boundary is based on the first 15 patients. A total of 4 out of 15 patients (26.7%) 95% CI: 8% - 55% exhibited a >2-fold increase in Par-4 levels at 3 months. This did not surpass the stopping bound for futility and thus indicates stopping of patient accrual based on the assumptions used for the Simon's two-stage design. 7 out of 19 patients (36.8%) 95% CI: 16% - 62% who exhibited at least a 2-fold increase at either 2 or 3 months of follow-up, 50% (95% CI: 26% - 74%) and 56% (95% CI: 31% -79%) exhibited a 1.5-fold and 1.25-fold increase respectively. To date, 10/19 patients finished 12-month follow-up, 4/19 and 5/19 finished 6-month and 3-month follow up respectively. 2 of 12 patients with less than 2-fold increase of Par-4 developed disease progression. None of 7 patients with 2-fold increase of Par-4 showed disease progression. Conclusions: Despite that the study was terminated prematurely, to our knowledge this is the first study in human to identify dynamic changes of serum Par-4 while on long-term of usage of HCQ. We also demonstrate trend of PFS benefit especially for subjects having 2-fold increase of Par-4 induction. Identification of tumors more Par-4 sensitive and predictive biomarkers of Par-4 induction are necessary to continue our investigation. Clinical trial information: NCT02232243.

e17545 Background: CDDP+NVBO as induction and concomitant regimen with RT has shown good efficacy outcomes and safety profile (Krzakowski, J Thor Oncol. 2008). The objective of this study was to evaluate the effectiveness and toxicities of the combination of CDDP and NVBO given at full doses concomitantly with RT in LA-NSCLC. Methods: Between February 2010 and May 2011, 26 chemo-naive patients (p) with histologically confirmed stage IIIA/IIIB unresectable LA NSCLC were treated. Treatment consisted of 4 cycles (cy) of NVBO 60 mg/m2 on days 1 and 8 and CDDP 80 mg/m2 every 3 weeks plus RT 66 Gy starting on day 1, cy 2. A standard Fleming two stage design is being used. The sample size is calculated with a power of 90% and a two-sided type 1 error allowance of 5%. Stage 1 included 25 pts, with subsequent expansion to a total of 45. Results: Patient’s characteristics were: Median age, 59 years (range 48-71); males, 92%; smokers, 60%; adenocarcinoma, 28% / squamous, 64%; stage IIIA, 54% / IIIB, 46%. 21 p completed the 4 cy treatment as per protocol. We analyzed 92 cy. Hematological toxicities (% cy): grade (g) 3/4 neutropenia, 42.3%; g3 anemia, 3.3%; g3 thrombocytopenia, 2.2%; febrile neutropenia, 1 p. Non-hematological toxicities (% cy): g3 oesophagitis, 6.5%; g4 diarrhea, 1.1%. 21 p were evaluable for response. 1 CR (4.8%), 17 PR (81%) and 1 SD (4.5%) were reported. ORR 85.8%. Survival analysis has not been performed due to short follow-up. Conclusions: The findings of this interim analysis confirm the previously reported outcomes of efficacy and safety with NVBO plus CDDP when administered concurrently with RT in stage IIIA/IIIB p. The trial has met the criteria for continuation into stage 2.

9 Background: The Z9001 study revealed adjuvant imatinib for 1 year significantly improved RFS in GIST patients (pts). The SSGXVIII study compared 3 years with 1 year of adjuvant imatinib for high risk GIST pts, but there was no study to evaluate shorter period of imatinib administration than 1 year. We conducted a randomized phase II study to compare 6 months (6-mo) with 12 months (12-mo) adjuvant imatinib for intermediate or high risk GIST pts. Methods: Inclusion criteria included ECOG-PS of 0 or 1, age between 20 and 79 years, and primary KIT-positive GIST with intermediate or high risk according to the Fletcher criteria. Pts were randomized assigned to the 6-mo or 12-mo treatment of imatinib 400 mg/day after complete resection. The primary endpoint was recurrence-free survival (RFS). The study was designed as a randomized screening trial to evaluate non-inferiority with margin of hazard ratio 1.67, 1-sided alpha 0.2 and power 0.8. Results: Ninety-two pts were randomly allocated the 6-mo group (n=45) or the 12-mo group (n=47) between Dec 2007 and Aug 2011, which was well balanced for baseline characteristics. One patient was ineligible due to non-GIST (desmoid) tumor at a central review. The proportions of pts completed their assigned adjuvant treatment were 80% in the 6-mo and 70% in the 12-mo group. The first interim analysis was conducted at Sep 2012 with the median follow-up time of 33 months. The 1- and 2-year RFS were 82% and 65% in the 6-mo group and 96% and 86% in the 12-mo group, respectively. Hazard ratio of recurrence was 1.81 (95%CI: 0.84-3.91), and the 2-sided log-rank p value was 0.12. Adjuvant imatinib was well tolerated, with one patient of Gr. 4 rash and no treatment-related death. Because of the lower efficacy of the 6-mo group than expected, the Data and Safety Monitoring Committee recommended the early release of first interim analysis results. Conclusions: Adjuvant Imatinib for 6-mo was inferior in efficacy to that for 12-mo in terms of RFS. Shortening of the adjuvant imatinib duration is not recommended for intermediate or high risk GIST pts. Clinical trial information: UMIN000000950.

11518 Background: CKS is a mesenchymal neoplasm associated with HHV8 infection. Though recombinant INFa is approved for treatment of AIDS-related KS, data is limited regarding the role of immune modulation in CKS therapy. Based on favorable responses in viral-induced cancers, we hypothesized that CTLA-4 and PD-1 blockade can induce tumor regression in CKS. We present pre-planned interim analysis of a phase II study of Nivo/Ipi in previously treated progressive CKS. Methods: CKS pts with progressive disease after > 1 line of systemic therapy and measurable disease received nivolumab 240mg d1,15,28 and ipilimumab 1mg/kg d1 q42 days until progression or toxicity. The primary endpoint was overall response rate (ORR) evaluated clinically, radiologically (RECIST) and metabolically (FDG-PET). Secondary endpoints include 6-months progression free survival rate (PFS) and safety. Exploratory endpoints included PD-L1/MMR by IHC, DNAseq (596 genes)/RNAseq (whole transcriptome) of tumor and matched blood specimens to explore CKS genomic traits and IO correlates: TMB and MSI status, MMR and PD-L1 protein expression, and immune gene transcript expression (PD-1, PD-L1, CTLA-4, and others) (Tempus Labs, Chicago, IL, USA). Results: Fifteen patients were enrolled and evaluable (Apr18-Jan20). Median age 72.5 (61-81), all male. At a median FU of 15.7 mo ORR as per RECIST was 66% (9 pts PR, 1 pt CR, 2 pts SD, 3 pts NE). Clinical ORR was 87% and metabolic ORR was 60%. Median PFS was not reached, 6mo PFS rate was 85% and 1y PFS rate was 75%. The safety profile was as expected with all pts experiencing G1 toxicity, 3 pts with G2 toxicity (1 hepatic, 2 asymptomatic lipase increase) and 2 pts with G3 toxicity (1 colitis, 1 asymptomatic lipase increase). One SAE was reported (TIA considered not related to therapy) and treatment was discontinued in 3 pts. Correlative results are available for 8 pts showing a trend for copy number loss in genes with tumor-suppressive activity (FOXA1, ELF3), no PDL1 expression, low TMB, microsatellite stability, but marked overexpression of CTLA-4, PD-1, PDL-1, CD40, OX40 and LAG3 RNA immune transcripts. Conclusions: The interim analysis of this prospective phase II study of nivolumab and low-dose ipilimumab demonstrates promising activity in progressive CKS, with 66% ORR and a 6mo PFS rate of 85%. Toxicity profile is as expected in this class of drugs. Correlative studies are preliminary, but warrant further investigation into genomic traits and immune gene expression profiles.

577 Background: Targeted therapy has shown remarkable treatment efficacy on the outcomes of patients with advanced renal cell carcinoma. However, this advance for treatment outcomes with targeted agents has been limited to patents with clear cell histology. The optimal treatment strategy for metastatic non-clear cell renal cell carcinoma (nccRCC) remains uncertained. Recently, several vascular endothelial growth factor inhibitors have shown efficacies for nccRCC. Thus, we designed a single-arm, open label phase II study to determine the efficacy and toxicity of pazopanib in patients with nccRCC. Methods: Patients with metastatic nccRCC except for collecting duct or sarcomatoid type received 800mg/day of pazopanib daily until progression of the disease or intolerable toxicity was observed. The primary objectives were progression free survival (PFS) and second objectives were overall survival (OS), treatment response and safety profiles. Results: A total of 29 eligible patients were enrolled from September 2012 to August 2014. The median age of the patients was 59 years (range, 30-77 years) and 21 patients were male. The median PFS was 8.3 months (95% CI, 4.0-12.6 months) and median OS was not reached (range, 1.5-34.7 months). Among all 29 patients, five patients (17.2%) are ongoing treatment without disease progression. Disease progression was observed in 16 patients (55.2%) during follow up period. Five patients (17.2%) experienced a treatment-related toxicity of grade 3 or more during the study and they stopped treatment in the end. Eight patients (27%) expired during follow up period but, there were no treatment-related deaths. Conclusions: This prospective phase II study showed that pazopanib demonstrated promising activity and tolerable safety in patients with nccRCC (ClinicalTrials.gov NCT01538238). Clinical trial information: NCT01538238.

12504 Background: Nimotuzumab (OSAG101, Theraloc) is a humanized monoclonal antibody (mAb) that binds to the EGFR. In preclinical studies the antibody has shown potent antitumor activity. Based on phase I data, the recommended dose has been established at 200 mg weekly. A previous phase II study in children with high grade brain tumors showed activity of nimotuzumab as a monotherapeutic agent, even in prognostically very unfavorable pontine glioma. No drug related side effects were reported. The present ongoing phase II study was aimed at evaluating the safety and efficacy of nimotuzumab monotherapy in patients (pts) with locally advanced or metastatic PC. Methods: Pts who failed standard chemotherapy with gemcitabine or another first line regimen for advanced disease and had at least one measurable lesion were eligible for the study. Nimotuzumab was given iv as induction therapy at 200 mg once weekly for 6 weeks. Follow up by CT was performed after 8 weeks. Pts continued receiving treatment 3-weekly until disease progression or unacceptable toxicity occurred. Endpoints included tumor response (RECIST), time to disease progression, and safety. Blood samples were collected prior to first dose, at end of infusion, and 3h, 6h, 48h, as well as every time before subsequent nimotuzumab doses were administered. Nimotuzumab concentrations in serum were measured by cellular ELISA. Results: Enrollment is complete, with treatment ongoing. In total, 55 pts were treated (28 women/ 27 men; ECOG status of 1 [n= 41] or 0 [n=14], median age 63.6 yrs [range 46–83 yrs]). Pts evaluable for response: n= 36; CR:0; PR:0; SD:6 pts (median TTP 19.2 weeks; 14.1–26.1). The only reported treatment-related adverse event was rash grade 1 in 1 pt. After 200 mg single dose, the mean value of Cmax was calculated to 141 ± 33 μg/ml. The t1/2 was calculated to 45 h, volume of distribution to 1.46 ± 0.3 l, respectively. The total clearance was determined to 23 ± 6 ml/h. The trough values after 168 h were 6.2 ± 6.3 μg/ml. Conclusions: These data confirm that nimotuzumab is safe and well tolerated. To improve efficacy, a combination trial with gemcitabine is planned. [Table: see text]

277 Background: Patients with metastatic pancreatic cancer (mPC) have poor prognosis. Given the activity of both capecitabine and erlotinib in pancreatic cancer, we hypothesized that combination use of two drugs in first-line therapy would improve clinical outcomes in these patients. Methods: A prospective, single arm, open-label, phase II study. Patients received capecitabine 1,000mg/m2 twice daily on days 1-14 in 3-week cycles combined with erlotinib 150 mg po daily for 18 weeks, until disease progression, unacceptable toxicity or withdrawal, with a follow-up visit performed at 30-days post-treatment. The primary endpoint was objective response rate measured with RECIST criteria. Results: A total of 32 patients were evaluated. Baseline characteristics: median age was 64 years (56-70), male: 50%, Karnofsky PS ≥ 80%: 94%, tumor histology: 93.5% adenocarcinoma, 49% moderately differentiated. 11 (34%) patients had surgery, 2 (6%) had prior radiotherapy and 3 (9%) prior chemotherapy. Median treatment duration was 61 days (6-156). 3 (9%) patients required dose reduction of capecitabine and 8 (25%) of erlotinib. Of the 32 patients, 6 completed the treatment period, 22 discontinued the study prematurely due to disease progression and 4 due to AEs. Disease control rate (confirmed complete response [CR], partial response [PR] and stable disease [SD] according to RECIST criteria) was 28.2%. 2 (6.3%) patients achieved PR and 7 (21.9%) had SD. After a mean follow-up of 6.3 months, the median progression-free (PFS) and overall survival (OS) was 2.10 and 4.3 months, respectively, with a 6-months survival rate of 43.8%. Safety analysis revealed that the main grade 1/2 toxicities were rash (34%), asthenia (31%), diarrhea (31%), stomatitis (22%) and emesis (22%). Three cases of grade 3 hand-foot syndrome and 1 case of infection due to biliary stent were detected. No toxicity grade 4 occurred. Conclusions: Capecitabine administered in combination with erlotinib is an active regimen in patients with metastatic pancreatic cancer with a favourable safety profile. These results suggest that this regimen could represent a first-line treatment option for these patients. No significant financial relationships to disclose.

424 Background: Advanced urothelial cancer progressing after first line systemic therapy is fatal. No agent in the second line or later setting has demonstrated improved survival although taxanes, pemetrexed, gemcitabine & vinflunine have activity & are used as palliative therapy. The Her2 pathway is up-regulated in some urothelial cancers and Her2 targeted therapy has enhanced chemotherapy effect in other cancers. We tested docetaxel with lapatinib, a Her1/Her2 TKI in urothelial cancer patients. Methods: Pts with measurable or evaluable urothelial cancerentered a single arm 2-stage phase II clinical trial, with PFS rate at 12 weeks as the primary endpoint in a Simon 2-stage design of 14+26 patients. The goal was a 12 week non progression rate of 60% - seen as promising compared to a rate of < 40% seen as not. In a 2-stage design if ≥ 6 of 14 patients had not progressed by 12 weeks the trial would continue to 40 pts. Secondary endpts: ORR, safety & OS. First 6 patients were given lapatinib 1250mg PO daily & docetaxel 60mg/m2 IV q3wk; docetaxel dose then increased to 75mg/m2 q3wk. Tumor tissue & circulating microenvironment were evaluated. Results: From July 2011 to July 2013, 15 pts were accrued. Median age 65 y, male 80%, ECOG 0 73%, Caucasian 73%, Mets: Liver 20%, Lung 20%, Bone 20%. PFS at 12 weeks 40%+/-13% - the trial was terminated after first stage. Reason off therapy: PD 10 (67%), toxicity 4 (27%). RECIST 1.1 best response: CR 1 (8%), SD 4 (31%), PD 8 (62%). Median OS: 6.3 (2.2, 12.7), PFS 2.0 (1.3, 6.6) months; 2 pts alive, follow up at 6.9 & 8.1 months. Common toxicities: diarrhea 80% (gr3 33%), vomiting 40% (gr3 26.7%), nausea 67% (gr3 26.7%) & fatigue 73.3% (gr3 6.7%). Conclusions: This phase II study of docetaxel with lapatinib in advanced urothelial cancer patients failed to provide sufficient efficacy for us to complete full accrual. One patient had a complete response and molecular correlatives may shed light on what may have predisposed to this. Intercurrently, another trial of maintenance lapatinib or placebo after chemotherapy in Her2+ patients reports no benefit (Powles ASCO 2015). Lapatinib alone or in combination is not recommended as therapy in urothelial cancer patients unless new tractable markers of response are developed. Clinical trial information: NCT01382706.
