2004 Background: Recurrent malignant gliomas (MG) are a universally fatal disease in desperate need of better therapies. Pleiomorphic xanthoastrocytomas (PXA) and juvenile pilocytic astrocytomas (JPA) typically have better outcomes, although when recurrent, also represent an aggressive disease with no proven effective chemotherapy. BRAFV600 alterations have been identified in a substantial proportion of gliomas, including glioblastoma (GBM), astrocytoma, PXA, and JPA. The phase 2, open-label, histology-independent VE-BASKET study of vemurafenib, a selective BRAFV600 kinase inhibitor, in patients with BRAF mutation-positive non-melanoma tumors, included those with gliomas in the ‘all-others’ cohort. We now report final data for patients with recurrent gliomas. Methods: Patients received vemurafenib (960 mg bid) until disease progression or unacceptable toxicity. The primary endpoint was investigator-assessed response rate; secondary endpoints included clinical benefit rate (confirmed complete or partial response or stable disease lasting ≥6 months), progression-free survival (PFS), overall survival (OS), and toxicity. ClinicalTrials.gov NCT01524978. Results: 24 patients (median age 32 years; 18 female, 6 male) with glioma were treated, including mg (n = 11; 6 GBM and 5 anaplastic astrocytoma [AA]), PXA (n = 7), anaplastic ganglioglioma (AG, n = 3), JPA (n = 2), and unknown (n = 1). In patients with mg (n = 11), best response included PR (n = 1; AA), SD (n = 5), PD (n = 3), and unknown (n = 2). Two patients with mg had durable SD lasting 12.9 months (GBM) and 14.9 months (AA). In patients with PXA (n = 7), best response included CR (n = 1), PR (n = 2), SD (n = 3), and PD (n = 1). Additionally, 1 patient with JPA and 1 with AG achieved a PR. The most frequent AEs included arthralgia (67%), melanocytic nevus (38%), palmar-plantar erythrodysesthesia (38%), photosensitivity reaction (38%) and alopecia (33%). Conclusions: Vemurafenib demonstrated activity in patients with BRAFV600 mutant glioma. The safety profile was similar to that seen in previous melanoma studies. Survival data will be presented. Clinical trial information: NCT01524978.

AbstractAsunercept (company code APG101 [Apogenix AG]; company code CAN008 [CANbridge Pharmaceuticals]) is a novel glycosylated fusion protein that has shown promising effectiveness in glioblastoma. This Phase I study was initiated to evaluate the tolerability and safety of asunercept in combination with standard radiotherapy and temozolomide (RT/TMZ) in Asian patients with newly diagnosed glioblastoma. This was the Phase I portion of a Phase I/II open label, multicenter trial of asunercept plus standard RT/TMZ. Adults with newly-diagnosed glioblastoma received surgical resection followed by standard RT/TMZ plus asunercept 200 mg/week (Cohort 1) or 400 mg/week (Cohort 2) by 30-min IV infusion. The primary endpoint was the safety and tolerability of asunercept during concurrent asunercept and RT/TMZ; dose-limiting toxicities were observed for each dose. Secondary endpoints included pharmacokinetics (PK) and 6-month progression-free survival (PFS6). All patients (Cohort 1, n = 3; Cohort 2, n = 7) completed ≥ 7 weeks of asunercept treatment. No DLTs were experienced. Only one possibly treatment-related treatment emergent adverse event (TEAE), Grade 1 gingival swelling, was observed. No Grade > 3 TEAEs were reported and no TEAE led to treatment discontinuation. Systemic asunercept exposure increased proportionally with dose and showed low inter-patient variability. The PFS6 rate was 33.3% and 57.1% for patients in Cohort 1 and 2, respectively. Patients in Cohort 2 maintained a PFS rate of 57.1% at Month 12. Adding asunercept to standard RT/TMZ was safe and well tolerated in patients with newly-diagnosed glioblastoma and 400 mg/week resulted in encouraging efficacy.Trial registration NCT02853565, August 3, 2016.

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.

601 Background: Pts with mCRC whose disease progressed after 5-FU, oxaliplatin, irinotecan and monoclonal antibodies have an unmet medical need. There is growing evidence suggesting an antitumoral effect of metformin in several tumor types, including CRC. Methods: Our primary objective was to evaluate the efficacy and safety of MetFU in heavily pretreated CRC pts with current progressive disease Last dose of 5-FU was administred at least 4 months prior to enrollment. Efficacy was defined as disease control rate at 8 weeks, using RECIST 1.1. Secondary endpoints were progression free survival, overall survival and tolerability. Single-arm Simon two-stage phase II trial was used. The treatment consisted of metformin 850 mg bid continuously plus 5-FU 425mg/m2 + Leucovorin (LV) 50 mg weekly for 4 weeks until disease progression, unacceptable toxicity or consent withdrawn in pts with mCRC who had progressed to conventional lines of treatment. Results: In the first stage, 22 pts were included: 12 pts (54%) were men, median age was 55 years and 59% were classified as an ECOG 1.14 pts faced treatment adverse events and 4 pts were excluded due to toxicity G3/4 - 2 pts had thrombocytopenia and 2 had limiting fatigue. Median time on treatment was 3.8 months, and 17 pts were evaluable for response: 6 pts (27%) had stable disease at 8 weeks as best response, with a median progression free survival (PFS) of 8.1 months. For the whole cohort, median overall survival was 5.6 months (IC95%: 3.1-8.2) and PFS was 2.0 months (IC95%: 1.8-2.3). Conclusions: Our results suggest that metformin may have antitumor activity when combined with 5-FU/LV in a subgroup of mCRC pts, with acceptable toxicity. It is unlikely that 5-FU alone had activity in these heavily treated pts. Clinical trial information: NCT01941953.

777 Background: Surgical resection can improve survival of patients with resectable colorectal liver metastases (CLMs). Here, we investigatedthe efficacy and safety of XELOX as perioperative treatment for patients with potentially resectable CLM. Methods: Patients with potentially resectable liver-only metastases from CRC were enrolled. The primary endpoint of this study was progression-free survival (PFS); and the secondary endpoints included objective response rate (ORR), R0 resection rate, overall survival (OS) and safety profile of perioperative treatment of XELOX. Eligible patients were treated with XELOX (oxaliplatin 130 mg/m2 on day 1 plus capecitabine 1,000 mg/m2 b.i.d. for 14 days every 3 weeks). Tumor remission was assessed by CT after 6 weeks (2 cycles) of chemotherapy. Resectability of CLM was assessed by CT after 12 weeks (4 cycles) of chemotherapy. Adjuvant chemotherapy using XELOX was started within 8 weeks after hepatectomy. Results: Thirty patients (17 males and 13 females) were enrolled from 10 medical sites between January 2010 and October 2011, with median age of 57.5 years (range: 32-77). Median PFS was 336 days (95% CI: 173~385), and median OS was 912 days (95% CI: 516~1332). The ORR was 40% (12/30). The conversion rate from unresectable to resectable was 43.3% (13/30). Among these 11 patients who had received surgery (2 had withdrawn consent), 10 (90.9%) had received R0 resection. Subgroup analysis shows that patients who had received hepatectomy had longer median PFS [95% CI] (382 days [210~518] vs. 173 days [111~337], p = 0.0268) and median OS [95% CI] (1332 [721~NA] vs. 516 [295~1046], p = 0.005). There were 4 patients with post-operation complications of ascites and/or hydrothorax, and 3 patients had early chemotherapy termination due to drug-related AEs, including leukopenia, hepatotoxicity and diarrhea. Conclusions: Perioperative chemotherapy of XELOX is an option for patients with potentially resectable CLM due to the effect in prolonging PFS and OS, as well as the manageable toxicities and post-operation complications. Clinical trial information: NCT00997685.

Background: In the PACIFIC study, progression-free survival (PFS) and overall survival (OS) of patients with unresectable, locally advanced, stage III non-small cell lung cancer (NSCLC) were prolonged by durvalumab as maintenance therapy after radical concurrent chemoradiotherapy using platinum-based antitumor agents. However, no data were obtained to reveal the efficacy of durvalumab after radiation monotherapy in patients unsuitable for chemoradiotherapy. Here, we describe an ongoing single-arm, prospective, open-label, multicenter phase II trial of durvalumab in patients with NSCLC ineligible for stage III chemoradiotherapy following radiation monotherapy (SPIRAL-RT study). Methods: Durvalumab at 10 mg/kg body weight is administered every 2 weeks after radiation therapy until individual patients meet the discontinuation criteria. The treatment duration is up to 12 months. The primary endpoint is the 1-year PFS rate. Secondary endpoints are response rate, PFS, OS, and safety. Durvalumab treatment after radiation monotherapy is expected to prolong 1-year PFS rate and have acceptable adverse events. Discussion: We are conducting an intervention study to investigate the safety and efficacy of durvalumab treatment in patients with NSCLC ineligible for stage III chemoradiotherapy following radiation monotherapy.

5040 Background: Sunitinib malate, an oral, multitargeted tyrosine kinase inhibitor of multiple receptors, showed significant efficacy in 168 pts with cytokine refractory mRCC, with a 42% objective response rate (ORR) and progression-free survival (PFS) of 8.2 months at 50 mg/day (4 weeks on treatment, 2 weeks off) per investigator assessment (Motzer et al. JAMA 2006;295:2516–24). This study was designed to determine the efficacy and safety of single-agent sunitinib when administered in a continuous 37.5 mg/day regimen. Methods: Pts with histologically proven mRCC, refractory to a cytokine-based regimen, were enrolled in this open-label, multicenter, phase II study. Eligibility criteria included measurable disease, ECOG PS 0/1, and adequate organ function. Pts were randomized to receive sunitinib in the morning (AM) or in the evening (PM) at a dose of 37.5 mg/day, with individual doses subsequently titrated based on tolerability. The primary endpoint was RECIST-defined ORR. Secondary endpoints included PFS, adverse events (AEs) and quality of life measures. Results: 107 pts were randomized to AM (54) or PM (53) dosing and have been on study a median of 6.8 months (0.4 to 13.3). As of October 2006, 55 pts have discontinued due to progression (37 pts [35%]), AEs (17 pts [16%]), and 1 consent withdrawal (1%); 47 pts (44%) were dose reduced to 25 mg/day due to grade 2/3 AEs, the most frequent being: asthenia (12%), hand-foot syndrome (8%), and diarrhea (5%). The most commonly reported (=5% of pts) grade 3/4 AEs were hypertension (10%), asthenia (9%), hand-foot syndrome (9%), anorexia (8%), and diarrhea (6%). 31 pts (29%) were maintained on continuous sunitinib at 37.5 mg/day, and 29 (27%) were escalated to 50 mg/day. There were no significant differences between pts who received AM or PM dosing. Quality of life results will be presented. The best response by RECIST per investigator assessment shows an ORR of 19% with 43 pts (40%) with =6 months of stable disease. The median PFS is 8.3 months. Conclusions: Sunitinib 37.5 mg/day continuous dosing has a manageable safety profile and demonstrates promising clinical benefit as second-line therapy in mRCC. This regimen provides alternative sunitinib dosing that can be explored in combination studies. No significant financial relationships to disclose.

5001 Background: The oral PARP inhibitor olaparib has shown antitumor activity in pts with SOC. Our multicenter study compared the efficacy of (Arm A) olaparib capsules plus P/C for 6 cycles then maintenance olaparib monotherapy vs (Arm B) P/C alone for 6 cycles and no further therapy in pts with PSR SOC (NCT01081951). Methods: Pts received 6 x 21-day(d) cycles of olaparib (200 mg bid, d1–10/21) + P (175 mg/m2 iv, d1) + C (AUC4 iv, d1), then olaparib monotherapy as maintenance (400 mg bid, continuous) (Arm A), or 6 x 21d cycles of P (175 mg/m2 iv, d1) + C (AUC6 iv, d1) then no further therapy (Arm B), until progression. Randomization (1:1) was stratified by number of platinum treatments and platinum-free interval. Primary endpoint: progression-free survival (PFS) by central review (RECIST 1.1). Secondary endpoints: overall survival (OS), objective response rate (ORR), safety. Archival tissue was collected where available for analysis of biomarker correlation. Results: Of 162 pts randomized (n=81 per arm), 156 received treatment (Arm A, n=81; Arm B, n=75) and 121 began the maintenance/no further therapy phase (Arm A, n=66; Arm B, n=55). Olaparib + P/C (AUC4) followed by maintenance olaparib showed a significant improvement in PFS vs P/C (AUC6) alone (HR = 0.51, 95% CI 0.34, 0.77; P=0.0012; median = 12.2 vs 9.6 months). OS data are immature (total events: 14%). ORR was similar for Arm A and Arm B (64 vs 58%). Most common AEs during the combination phase were alopecia (74 vs 59%), nausea (69 vs 57%) and fatigue (64 vs 57%) for Arm A vs Arm B, respectively. Pts with grade ≥3 AEs (65 vs 57%), serious AEs (SAEs: 15 vs 21%) and AEs leading to treatment discontinuation (19 vs 16%) were similar for Arm A vs Arm B. Most common AEs during maintenance/no further therapy were nausea (50 vs 6%) and vomiting (29 vs 7%). 29 vs 16% of pts had grade ≥3 AEs, 9 vs 7% had SAEs and 8% vs N/A discontinued due to AEs in the olaparib vs no treatment arms, respectively. There were no fatal AEs. Conclusions: In pts with PSR SOC, olaparib plus P/C (AUC4) followed by olaparib 400 mg bid monotherapy maintenance treatment resulted in a significant improvement in PFS vs P/C (AUC6) alone.

11006 Background: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal malignancy of the gastrointestinal tract. Advanced GIST is treated with tyrosine kinase inhibitors (TKIs). Most patients (pts) develop resistance over time. We reported in 2013 (Van Looy CTOS) that cabozantinib (cabo), a TKI targeting KIT/MET/AXL/VEGFR, showed activity in GIST xenograft models through inhibition of tumor growth, proliferation and angiogenesis, both in imatinib-sensitive and -resistant tumors (Gebreyohannes Mol Cancer Ther 2016;15:2845-28). Cohen (Cancer Res 2015;75:2061-70) found that cabo can overcome compensatory MET signaling in GIST in vitro. EORTC 1317 assessed the safety and activity of cabo in pts who had progressed on imatinib and sunitinib. Methods: In this multi-center, open label, single arm Phase 2 study eligible metastatic GIST pts received 60 mg (freebase weight) cabo p.o./d. Primary endpoint was progression-free survival rate at wk 12, assessed by local investigator per RECIST 1.1. If at least 21 of 41 eligible and evaluable pts were progression-free at wk 12, the activity of cabo was sufficient to warrant further exploration (A’Hern one-stage design). Results: A total of 50 consenting pts were eligible and started treatment between 02/2017 and 08/2018, with 16 (32%) still continuing cabo at the database cut-off in 01/2019. The number of 3 wk treatment cycles ranges from 2-28+. Among the first 41 eligible and evaluable pts, 24 were progression-free at wk 12, satisfying the study decision rule. Among all 50 pts, 30 were progression-free at wk 12 (60%, 95% confidence interval (CI) 45-74%). A total of 7 pts achieved a confirmed partial response (PR) (14%, 95%CI 6-27%) and 33 had stable disease (SD) (66%, 95%CI 51-79%). Progression as best response was seen in 9 pts (18%, 95%CI 9-31%), one was not evaluable. Disease control (PR+SD) was achieved in 40 pts (80%, 95%CI 66-90%). Median progression-free survival was 6.0 mo (95%CI 3.6-7.7). The most common cabo-related grade ≥3 adverse events were diarrhea (74%), hand-foot syndrome (58%), fatigue (46%), hypertension (46%), weight loss (38%) and oral mucositis (28%), with 33 (66%) pts requiring dose reductions, 25 (50%) treatment interruptions and no cabo-related deaths. Conclusions: EORTC 1317 met its primary endpoint, with 24/41 pts (58.5%) being progression-free at wk 12. Results of this trial confirm preclinical data and warrant further exploration of cabo in GIST. Clinical trial information: NCT02216578.

Summary Purpose Apatinib, a new tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, has shown promising efficacy against several solid cancers, but evidence of its efficacy against relapsed and refractory nasopharyngeal carcinoma is limited. We investigated the efficacy and safety of apatinib for relapsed and refractory nasopharyngeal carcinoma in an open-label, single-arm, phase II clinical trial. Fifty-one patients with relapsed and refractory nasopharyngeal carcinoma in the First Affiliated Hospital, Zhengzhou University, who met the inclusion criteria were enrolled in the study. All patients received apatinib at an initial dose of 500 mg daily (1 cycle = 28 days). The primary and secondary endpoints were overall response rate, progression-free survival, and overall survival. We evaluated treatment effects and recorded apatinib-related adverse events by performing regular follow-ups and workup. The overall response rate (complete and partial responses) was 31.37% (16/51). The median overall survival and progression-free survival were 16 (95% CI, 9.32–22.68) and 9 months (95% CI, 5.24–12.76), respectively. Most patients tolerated treatment-related adverse events of grades 1 and 2; hypertension (29, 56.86%), proteinuria (25, 49.02%), and hand–foot syndrome (27, 52.94%) were the most common adverse events. There were no treatment-related deaths. Apatinib showed good efficacy and safety in patients with relapsed and refractory NPC.
