CRA9003 Background: Gq/11 mutations are early oncogenic events in UM resulting in MAPK pathway activation. We demonstrated decreased viability in UM cell lines harboring Gq/11 mut with sel, a small molecule inhibitor of MEK1/2 (Ambrosini, CCR 2012). Methods: We conducted a 16 center randomized phase II study of hyd-sulfate sel 75 mg BID vs TMZ 150 mg/m2 daily for 5 days in 28-day cycles (or DTIC 1000 mg/m2 q21 days) for patients (pts) with metastatic UM with a Q209 Gq/11 mut who have not received prior TMZ/DTIC. The primary endpoint was progression free survival (PFS). Secondary endpoints included overall survival (OS) and response rate (RR). Select pts underwent tumor biopsies at baseline and after 14 (+/- 3 days) of sel. Our statistical plan required ≥80 pts randomized and ≥68 events to detect a PFS hazard ratio of 0.6 (p=0.1). Randomization was stratified by mut (Gq vs G11), M stage and number of prior therapies (tx). Tumor assessment occurred every 4 weeks (wks) for 8 wks and then every 8 wks using RECIST 1.1. Pts receiving TMZ who progressed could receive sel (TMZ→sel). Results: 80 pts were randomized. Sel (n=39): median age 66 (range 32-86), 54% male, 54% G11 mut, median ECOG PS 0 (range 0-1), 97% M1c, median prior tx 0 (range 0-2). TMZ (n=41): median age 60 (range 34-81), 63% male, 58% G11 mut, median ECOG PS 0 (range 0-1), 93% M1c, median prior tx 0 (range 0-2). 11/39 (28%) pts on sel experienced grade (gr) 3 toxicity (tox) manageable with dose modification (5 CPK elevation, 3 LFT elevation, 1 rash, 1 lymphopenia, 1 edema). 1/41 (2%) pt on TMZ experienced gr 3 tox (neutropenia). No gr 4/5 tox occurred. 28 pts on sel underwent paired tumor biopsies with inhibition of pERK and cyclinD1 observed by Western blot at day 14. At interim analysis (9/25/12), 55 pts were evaluable with 45 progression events and 16 deaths. Sel (n=27): median PFS 16 wks (95% CI 8-30.9), RR 11%, median OS 11.8 months (95% CI 4.8-not reached). TMZ (n=28): median PFS 4 wks (95% CI 3.7-15), RR 0%, median OS 4.7 months (95% CI 4.3-14.3). TMZ→sel (n=25): median PFS 8.1 wks (95% CI 7-15), RR 0%. Conclusions: Sel is the first drug to ever show improved clinical activity in UM relative to TMZ. Sustained target inhibition is observed with sel. Final results will be presented. Clinical trial information: NCT01143402.

10040 Background: Vorolanib (CM082) is a multi-target tyrosine kinase inhibitor including VEGF, PDGF, c-kit, and Flt-3. Toripalimab (JS001) is a humanized IgG4 mAb against programmed death-1 (PD-1) with clinical activity in metastasis melanoma but not in its mucosal subtype. In this phase II study (NCT03602547), we investigated the safety and efficacy of CM082 in combination with JS001 in patients (pts) with advanced mucosal melanoma. Methods: The study enrolled pts from 18 to 75 years-old with histologically confirmed metastatic mucosal melanoma, ECOG PS 0-1, no prior systemic anti-cancer treatment. Eligible pts were treated with CM082 tablet (150 or 200 mg once daily) combined with JS001 (240mg every 2 weeks, IV, Q2W) until confirmed disease progression or unacceptable toxicity. Clinical response was evaluated every 8 week. The primary endpoint was overall response rate (ORR) using RECIST v1.1. Secondary endpoints included progression-free survival (PFS), overall survival (OS), disease control rate (DCR), duration of remission (DOR), and time to first remission (TTR) according to RECIST v1.1 and iRECIST. The safety was also assessed. Results: Between July 2018 and April 12, 2019, 40 pts (19 pts in 150mg group; 21 pts in 200mg group) were enrolled and 38 pts were evaluable for tumor response (150mg n = 18, 200mg n = 20), with 4 (22.2%) confirmed partial response (PR), 6 (33.3%) stable disease (SD) and 8 (44.4%) progression disease (PD) in the 150mg CM082 group; 3 (15%) PRs (including 2 unconfirmed), 10 (50%) SD, and 7 (35%) PD were reported in the 200mg CM082 group. Tumors shrank in 10 pts (56%) in the 150mg group and 10 pts (50%) in the 200mg group. At data cut-off (November 28, 2019), 29 pts had PFS events (150mg n = 12; 200mg n = 17). The median PFS was 5.7 (95% CI 2.0, NE) months and 5.6 (1.9, 7.7) months in the two groups, respectively. The most common treatment-related adverse events (AEs) were grade 1 or 2, including leukopenia, elevated LDH, increased ALT, neutropenia, increased AST, and elevated GGT. Common grade 3 or higher adverse events ( > 10%) were increased ALT (12 pts, 30%), increased AST (11 pts, 27.5%), neutropenia (6 pts, 15%) and elevated GGT (6 pts, 15%). Eight pts had 9 serious AEs (SAEs). The study is still ongoing and more data will be presented in the future. Conclusions: PFS benefit was observed in both 150mg and 200mg subgroups. This study demonstrated potentially improved efficacy with predictable toxicities of CM082 in combination with JS001 therapy, which may be an effective treatment option for pts with advanced mucosal melanoma. Clinical trial information: NCT03602547.

7522 Background: Vandetanib (V) is an inhibitor of vascular endothelial and epidermal growth factor receptors. This trial sought to determine whether maintenance V, given after standard chemotherapy (CT) and radiation (RT), prolonged progression-free survival (PFS) in responding patients with SCLC. Secondary endpoints: overall survival (OS) and toxicity. Methods: Phase II randomized, study of V 300 mg PO daily or placebo (P). Eligibility: complete (CR) or partial response (PR) to platinum-based CT, ECOG PS 0–2 and completion of RT (thoracic or prophylactic cranial). Statistics: 80% power to detect a 2.5 months improvement in median PFS (estimate for P of 4 months) using a 1-sided 10% level test (100 eligible patients; 77 events). Results: Between May 2003 and March 2006, 107 patients were accrued from 17 centres. Median follow up: 13.5 months. 46 had limited disease (LD); 61 extensive disease (ED). There were fewer PS 0 patients (11 vs. 20), and fewer had CR to initial CT (4 vs. 8) in the V arm. V patients were more likely to experience toxicity and require dose modification. The most frequent toxicities leading to dose modifications were gastrointestinal and rash. Clinically asymptomatic QTc prolongation was observed in 8 V patients. 83 of 107 patients developed progressive disease (43 on V; 40 on P). The median PFS for V was 2.7 months (80% C.I.: 1.1 –4.5) and 2.8 months for P (80% C.I.: 1.9 –5.6); estimated hazard ratio (HR) was 1.01 for V vs P (80% C.I.: 0.75 –1.36, 1-sided P-value = 0.51). Median OS for V was 10.6 months vs. 11.9 months for P; HR was 1.43 for V vs. P (80% C.I.: 1.00 –2.05, 1-sided P-value = 0.90). In a planned subgroup analysis, a significant interaction was noted (P-value = 0.01); with LD patients randomized to V having a longer OS (HR: 0.45, 1-sided P-value = 0.07), whereas ED patients randomized to V had a shorter OS compared to P (HR: 2.27, 1-sided P-value = 0.996). Conclusion: V failed to demonstrate efficacy as maintenance therapy for SCLC. Future targeted therapies should probably be explored concurrently with chemotherapy. This study was supported by the Canadian Cancer Society and AstraZeneca. [Table: see text]

2066 Background: To evaluate the efficacy and tolerability of ifosfamide, carboplatin and etoposide ( ICE ) in patients with recurrent glioblastoma. Methods: This was an open-label, single-center phase II trial. Forty-two patients with first recurrent glioblastoma after surgery, standard radiotherapy and a first-line temozolomide-based or ACNU-based chemotherapy, were enrolled.The primary endpoint was progression-free survival at 6 months ( PFS-6 ), and secondary endpoints were response rate, toxicity, and survival. Chemotherapy consisted of Ifosfamide ( 700 mg / m2 on day 1, 2 and 3 ), carbopaltin ( 100 mg / m2 on day 1 ), etoposide ( 70 mg / m2 on day 1, 2, and 3 ), every 6 weeks. Results: PFS-6 was 37 %. The median PFS was 17 weeks. Response rate was 27 %. Adverse events were generally mild ( grade 1 or 2 ) and consisted mainly of alopecia. Conclusions: This regimen is well tolerated and has activity in patients with recurrent glioblastoma. No significant financial relationships to disclose.

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.

5592 Background: Cytotoxic chemotherapy (CT) is the current standard treatment for metastatic/recurrent SCCHN. The prognosis for these patients (PTS) is poor with a median progression free survival (PFS) of 4 months with CT. Survival in PTS with SCCHN may correlate inversely with the number of angiogenic growth factors secreted. Sorafenib is a potent inhibitor of c-Raf, b-Raf, VEGFR-1/2/3 and PDGFR-β. To investigate the hypothesis that a multi-targeted TKI added to chemotherapy would improve outcomes in patients with metastatic/recurrent SCCHN, we performed a phase II trial of   paclitaxel and carboplatin and sorafenib (PCS). Methods: PTS were required to have ECOG PS 0-1, measurable disease, controlled blood pressure, and may have received one regimen of induction, concomitant or adjuvant CT, but not CT for recurrent/metastatic disease. Sites of primary disease excluded nasopharynx and paranasal sinus. Treatment consisted P 200mg/m2 and C AUC 6 intravenously on day 1 followed by S 400 mg orally bid (days 2-19) in every 3-week cycles.  Primary endpoint was PFS, targeting median PFS of 6 months (M). Secondary endpoints include overall survival (OS), response rate (RR), exploratory biomarkers, and toxicity. Results: Forty-eight PTS with SCCHN were enrolled with 44 PTS evaluable for PFS and response using RECIST. Median age: 56 years (22-79 years), 89% male, median ECOG PS 1.  Median follow-up was 24.1 M.  RR was 55% (n=24), disease control rate was 84% (n=37), median PFS was 8.51 M (95% CI: 5.98 ~ 13 months), and median OS was 22.6 M (95% CI: 13.1 - NA months). Grade ³3 treatment related toxicities included hand-foot syndrome (n=10), neutropenia (n=5), pain (n=6), elevated lipase (n=4), elevated amylase (n=3), anemia (n=3), fatigue (n=2), hypertension (n=2), neuropathy (n=2), febrile neutropenia (n=2), and thrombocytopenia (n=2).  Conclusions: The combination of PCS was well tolerated and had encouraging activity in recurrent/metastatic SCCHN. Blood-based and tissue biomarkers are being analyzed.  Final outcomes, toxicity, and correlative biomarker data will be reported.

406 Background: Zibotentan (Z) is an oral specific ETAR antagonist. The ETAR is over expressed in colorectal cancer, and pre-clinically, antagonism of the ETAR has been shown to enhance cytotoxicity when combined with cytotoxics such as 5-FU. This multi-center, randomized, double-blind, placebo-controlled phase II study evaluated the safety and anti-tumor activity of irinotecan and 5-FU (as the FOLFIRI regimen) in combination with Z in advanced colorectal cancer. Methods: Patients (pts) with advanced colorectal cancer who had progressed after oxaliplatin-containing chemotherapy (FOLFOX) were randomized (1:1) to receive 10 mg O.D Z/placebo (continuous dosing) with standard dose FOLFIRI for a maximum of 12 cycles. Z /placebo could be continued until progression or unacceptable toxicity in those patients with a documented response. The primary objective was progression–free survival (PFS) with secondary endpoints of safety and blood and archival tumor samples collected for translational work including circulating tumour cell (CTC) analysis. This study was run as part of the AZ/NCRN alliance, endorsed by Cancer Research UK (CRUKE/09/023) and coordinated by the Wales Cancer Trials Unit, Cardiff University. Results: A total of 111 patients were recruited: 61% men, median age of 62 years. Z was well tolerated with G3/4 toxicity balanced between both groups (34/55 patients in Z and 38/56 in placebo group). The study was terminated before the planned number of pts (122) were recruited due to lack of efficacy of the drug in two other tumour types. Median PFS was 4.0 months in the Z group and 7.4 months in the placebo group (HR=1.86, 95% CI 1.20 to 2.87, p=0.005). The CTC analysis in relation to outcome in the placebo group will be presented. Conclusions: Zibotentan does not have anti-cancer activity in combination with FOLFIRI in patients with colorectal cancer treated with previous FOLFOX. Taken in consideration with the other trial data we do not recommend the further development of zibotentan in oncology. Clinical trial information: 73199181.

454 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 2nd-line tx in a phase III trial comparing pmab + FOLFIRI vs FOLFIRI alone. Here, we describe the results of SPIRITT, a multicenter, randomized phase II study evaluating pmab + FOLFIRI and bev + FOLFIRI in pts with WT KRAS mCRC previously treated with a 1st-line bev + oxaliplatin (Ox)-based chemotherapy regimen. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + FOLFIRI Q2W or to bev 5.0 or 10.0 mg/kg + FOLFIRI Q2W. Eligibility criteria included: WT KRAS mCRC, ECOG ≤ 1, no prior irinotecan or anti-EGFR tx, and tx failure of prior 1st-line bev + Ox-based therapy (≥ 4 cycles). The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 182 pts with WT KRAS mCRC were randomized. All pts received tx. Efficacy results are shown (table). Worst grade of 3/4 adverse events (AE) occurred in 78% of pts in the pmab + FOLFIRI arm and 65% in the bev + FOLFIRI arm. Grade 5 AEs occurred in 7% of pts in the pmab + FOLFIRI arm and 7% in the bev + FOLFIRI arm. Tx discontinuation due to any AE was 29% in the pmab + FOLFIRI arm and 25% in the bev + FOLFIRI arm. Conclusions: In this estimation study of pts with WT KRAS mCRC that previously received bev + Ox-based tx, the PFS hazard ratio (HR) was 1.01 (95% CI: 0.68 - 1.50). The OS HR was 1.06 (95% CI: 0.75 - 1.49). The observed ORR was higher in the pmab + FOLFIRI arm. 54% of bev + FOLFIRI pts received subsequent anti-EGFR tx. The safety profile for both arms was similar to previously reported studies. Tx discontinuation rates due to AEs were similar between the arms. Clinical trial information: NCT00418938.

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.

4069 Background: BKM120 is an oral pan-class I phosphatidylinositol-3-kinase (PI3K) inhibitor, which showed promising activity in breast cancer and squamous cell carcinoma of head and neck. We prospectively investigated clinical activity, safety and biomarkers of BKM120 in advanced esophagus squamous cell carcinoma (ESCC). Methods: We conducted a multicenter phase II study of BKM120 monotherapy in patients with pretreated advanced ESCC. All the patients had a treatment history of fluoropyrimidine and platinum. BKM120 of 100 mg/day was orally administered in a 28-day cycle. A primary end-point was a disease control rate (DCR). Using Simon’s minimax two-stage design, total of 41 patients were required for primary analysis (promising DCR of 60%, non-promising one of 40%, one-sided alpha level of 10% and power of 90%). The response rate (RR), progression-free survival (PFS), overall survival (OS), and safety were also evaluated as secondary endpoints. Tumor samples for all the patients were required for gene alternation analysis in comprehensive genomic profiling assay (FoundationOne). Results: A total of 42 patients (median age, 62.5 years; performance status 0/1 = 28/14) were enrolled. One ineligible patient was excluded from primary analysis. Nineteen and two patients had SD and unconfirmed PR. DCR was 51.2% (95% CI, 35.1% to 67.1%), which met the primary endpoint of the study. Median PFS and OS was 2.0 months (95% CI, 1.8 to 3.2 months) and 9.0 months (95% CI, 6.4 to 11.7 months), respectively. Common grade 3 or 4 adverse events were anorexia, rash, hyponatremia, lipase increased, and abnormal hepatic function (including increased transaminase levels), which were profiles similar to previous studies of BKM120 monotherapy. No treatment-related deaths occurred. Further analyses of the gene alternation are ongoing. Conclusions: BKM120 monotherapy showed promising efficacy and mild toxicity profile in patients with pretreated advanced ESCC. BKM120 is worth evaluating in a further confirmatory study. Result of subgroup analyses with respect to gene alternation status will be presented. Clinical trial information: UMIN000011217.

Randomized, open-label, phase II study comparing five-weekly S-1 plus cisplatin (SP) with tri-weekly capecitabine plus cisplatin (XP) in chemotherapy-naïve patients with HER2 negative advanced gastric cancer (AGC): OGSG 1105 HERBIS-4A trial.

102 Background: This phase II study aimed to investigate the safety and efficacy of XP compared to SP in the first-line treatment of HER2 negative AGC. Methods: Patients were randomly assigned to receive either SP (S-1 at 40–60 mg twice daily for 21 days plus cisplatin at 60 mg/ m2 on day 8, every 5 weeks) or XP (capecitabine 1,000 mg/m2 twice daily for 14 days plus cisplatin 80 mg/m2 on day 1, every 3 weeks). Primary endpoint was response rate (RR), and secondary endpoints were progression-free survival (PFS), overall survival (OS), time to treatment failure (TTF), and adverse events. Results: 84 eligible patients were randomly assigned to receive SP ( N = 41) or XP ( N = 43). No statistical difference was observed in overall RR between the SP and XP groups [51.2% (95% CI, 35.1% to 67.1%) vs. 53.5% (95% CI, 37.7% to 68.8%), P = 1.000]. Despite not significant, however, SP vs. XP showed a trend toward better PFS [median, 5.9 months vs. 4.1 months; hazard ratio (HR), 0.763; 95% CI, 0.462 to 1.259; P = .284] and OS (median, 13.5 months vs. 10.0 months; HR, 0.776; 95% CI, 0.485 to 1.244; P = .290). This trend in the SP vs. XP comparison was more pronounced in TTF (median, 4.5 months vs. 3.1 months; HR, 0.651; 95% CI, 0.421 to 1.006; P = .052). Common grade 3 to 4 hematological toxicities were neutropenia and anemia (SP group, 23% and 23%; XP group, 35% and 28%). Grade 3-4 anorexia and hyponatremia were more frequently seen in the XP group (31% and 16%) compared to the SP group (13% and 5%). Treatment-related deaths occurred in one patient (2.3%) in the XP group. Conclusions: XP failed to demonstrate the superior efficacy over SP. Higher incidence of severe toxicities by XP suggests SP as the standard 1st line chemotherapy for HER2 negative AGC in Japan. Clinical trial information: UMIN000006755.
