Background: Several single chemotherapeutic agents have been evaluated as the second-line treatment of advanced urothelial carcinoma. Despite encouraging efficacy outcomes, toxicity has often led to dose modifications or discontinuation. We aimed to assess the safety of vinflunine in a particular population of advanced transitional cell carcinoma of urothelium (TCCU), that were exposed to the previous toxicity of chemotherapy. Methods: This is an open-label, prospective, single-center pilot study to evaluate the response rate and safety profile of vinflunine in patients with advanced TCCU. It was planned to enroll 25 evaluable patients. Eligible patients are those with progressive disease after first-line platinum-based regimen for advanced or metastatic disease. Results: The study was prematurely closed due to two sudden deaths that were judged by the review board as treatment-related. Only ten patients were evaluated and received at least one cycle of vinflunine. All but one were male and seven underwent radical surgery. Eight had a distant metastasis (mainly lung and/or liver). Disease control rate was 40%, four patients had a partial response with median duration of response of 3.5 months. The median overall survival was 3.2 months (95% CI:1.67- 4.73). There were three serious adverse events namely two sudden deaths and one grade 4 thrombocytopenia. Nine grade 3/4 adverse events occurred. The most common all-grade adverse events were fatigue (50%), constipation (40%) and vomiting (40%). Moreover, grade 3 fatigue occurred in 30% of patients. Only one patient, who achieved PR for 5 months, was fit to receive further cytotoxic chemotherapy. Conclusion: The activity of vinflunine in advanced urothelial carcinoma came at the expense of its safety. The use of vinflunine has to be limited to the selected group of patients. However, this is a single institute experience in a limited number of patients.

PURPOSE: To determine the efficacy and toxicity of the drug combination of carboplatin, paclitaxel, and gemcitabine in patients with advanced urothelial carcinoma. PATIENTS AND METHODS: Patients eligible included those with advanced urothelial malignancy of any histology, no previous chemotherapy for metastatic disease, Southwest Oncology Group performance status of 2 or less, serum creatinine levels of 2 mg/dL or less, and adequate bone marrow and hepatic function. Treatment consisted of paclitaxel 200 mg/m2, carboplatin (target area under the curve = 5) on day 1, and gemcitabine 800 mg/m2 on days 1 and 8, repeated every 21 days. RESULTS: Forty-nine patients (44 men and five women) were enrolled; the patients’ median age was 63 years, and their median creatinine clearance was 78 mL/min (range, 26 to 165 mL/min). Forty-three patients had transitional cell carcinoma, and six had squamous cell carcinoma or mixed histology. Ten patients had metastases to lymph nodes only, six had locally advanced disease, four had locally recurrent disease, 24 patients had visceral metastases, and five had soft tissue metastases. Twenty-one patients had disease in one site, 16 in two sites, and 12 in three sites. A total of 272 cycles were administered (median, six cycles; range, 1 to 15 cycles). Major toxicities were grade 3 and 4 neutropenia in 17 and 19 patients, respectively; grade 3 and 4 thrombocytopenia in 15 and six patients, respectively; grade 3 and 4 anemia in 10 and two patients, respectively; grade 3 neuropathy in four patients; and diarrhea in two patients. The incidence of febrile neutropenia was 1.4%; no patients died of drug toxicity. Forty-seven of the 49 patients were assessable for response. Fifteen (32%) patients experienced a complete response, and 17 (36%) patients experienced a partial response (32 of 47 patients, 68%; 95% confidence interval, 56.27 to 82.86). Responses were seen in all sites, including 15 (68%) of 22 patients with visceral metastases. The median survival was 14.7 months, with a 1-year survival of 59%. CONCLUSION: Combination paclitaxel, carboplatin, and gemcitabine is active; an encouraging number of patients with advanced urothelial carcinoma treated with this regimen experienced complete remission.

4531 Background: Immune-checkpoints inhibitors (ICIs) represents the standard of care for platinum-pretreated advanced urothelial cancer patients (pts). By enhancing T-cell activation, a unique spectrum of inflammatory side effects has emerged, also known as immune-related adverse events (irAEs). Data regarding the association between irAEs and pts outcomes are conflicting. Here we conducted a retrospective analysis to investigate the association between irAEs profile and disease outcome in metastastic urothelial carcinoma (mUC) pts. Methods: Medical records from pts with mUC included in clinical trials between July 2013 and June 2018 and treated with ICIs were reviewed. Pts previously treated with platinum-based chemotherapy or cisplatin ineligible pts who had not been previously treated with chemotherapy were included. Clinical responses were assessed as complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD) according to RECIST v1.1. Adverse events were graded based CTCAE v4.03. Overall survival (OS) was calculated from the date of initiation of ICI to the date of death. X2 test was used to determine differences in rates. OS was estimated using Kaplan-Method and long rank test was used to assess differences between groups. All analyses were performed using SPSS v21. Results: From a total of 52 pts, 44 (84.6%) were treated with ICI monotherapy and 8 (15.3%) in combination (anti-CTLA4 or targeted therapy). Median age was 65 years, 42 pts (80.8%) were male, 44 patients (84.6%) had ECOG PS 0-1, 14 pts (26.9%) had liver metastasis. Overall irAEs were observed in 30 pts (57.7%) and 10 pts (19.2%) developed grade 3/4 irAES. Most common grade 3/4 irAEs were diarrhea (6.6%), rash (6.6%) and hepatitis (6.6%). Disease control rate (CR [26%]+PR[33%]+SD[20%]) was higher for patients with irAEs compared to those patients who did not developed irAEs (CR [13.6%]+PR[0%]+SD[22.7%], this difference was statically significant (P = 0.002). Median OS was 11.23 mo (CI 95%, 3.76-18.70) for the overall cohort, while median OS was 21.91 mo for those patients with irAEs compared to 6.47 mo in patients who did not developed irAEs (P = 0.004). Conclusions: In this analysis we found that the development of irAEs was a strong predictor of improved OS in mUC patients treated with ICI.

13001 Background: Pertuzumab (P), a humanized HER2 antibody, represents a new class of targeted agents called HER dimerization inhibitors (HDIs). P inhibits dimerization of HER2 with EGFR, HER3 and HER4, and subsequently inhibits signaling through MAP and PI3 kinases. Single agent P has demonstrated clinical benefit in advanced OC (ASCO 2005 abstract #5051). Methods: 40 pts with platinum-resistant OC (progressed within 6 months of receiving a platinum-based chemotherapy) were enrolled in this 1:1 randomized, double blind, placebo controlled trial of gemcitabine with or without P. Gemcitabine was administered IV on day 1 and 8 at 800 mg/m2 of a 21 day cycle. Blinded placebo or 420 mg P was administered IV on day 1. Gemcitabine was dose reduced for neutropenia or thrombocytopenia. P was not dose reduced. Results: 40 pts have been enrolled and treated with at least 1 cycle of gemcitabine in combination with blinded study drug. The median age was 58.5 (range 18–82); 26 had PS ECOG 0, 13 ECOG 1, 1 ECOG 2. The most common grade 3/4 events were neutropenia in 7 pts (17.5%), thrombocytopenia in 6 pts (15%), small bowel obstruction in 4 pts (10%), constipation in 3 pts (7.5%) and elevated ALT in 3 pts (7.4%). There was one grade 3 diarrhea, but no grade 3 or 4 rash. There were 4 serious adverse events (SAEs) attributed to study drug. These were a pleural effusion, thrombocytopenia, febrile neutropenia, and a deep vein thrombosis. Nine pts required one or two dose reductions of gemcitabine for hematological toxicity. Of 29 pts with post-baseline echo or MUGA values obtained, no pt had LVEF drop to <50%. The adverse events evaluated after 40 pts did not meet the prespecified criteria to call for an independent safety monitoring board evaluation of unblinded data. Conclusions: Preliminary safety data indicate that pertuzumab or placebo combined with gemcitabine is well tolerated with no unexpected additive toxicity. The nature and frequency of the adverse events are similar to what has been observed with either single agent gemcitabine or P. Updated data will be presented at ASCO. [Table: see text]

9545 Background: Although imatinib induces durable clinical benefit in pts with metastatic GIST, resistance may emerge. AMN107 is a novel agent rationally designed to inhibit the PDGFR, KIT and Bcr-Abl tyrosine kinases. It has been shown to inhibit the proliferation of both imatinib-sensitive and imatinib-resistant GIST cells in vitro. Methods: Cohorts of imatinib-resistant GIST pts with radiological progressive disease (PD) were treated with AMN107 alone (400 mg p.o. bid) or with escalating doses of AMN107 (200 mg qd, 400 mg qd, or 400 mg bid) in combination with imatinib (400 mg p.o. bid). Pharmacokinetic (PK) analyses were performed for both AMN107 and imatinib. Serial tumor assessments included CT and 18FDG-PET scans. Results: As of 30 November 2005, 30 pts (13 women and 17 men), median age 51 yr (range 24–83) received AMN107 alone (n=18) or in combination up to 400 mg qd with imatinib (n=12) for 7 to 98 days (median 49 days). This study continues to accrue. Serious adverse events (SAE’s) reported in four patients deemed related to disease included abdominal pain, peritonitis and anemia. Grade 1/2 drug-related adverse events included hyperbilirubinemia, myalgias, peripheral edema and skin rash. Dose-limiting toxicity (Grade 3 elevated bilirubin) was reported in one pt on AMN107 alone. Efficacy data available for 18 patients show that three patients experienced progressive disease and 15 patients had stable disease, although the duration of follow-up was short. PK results in a limited number of patients showed that the effect of imatinib co-administration on AMN107 PK appears to be minimal, while AMN107 increases imatinib exposure on the average by 50%. Conclusions: AMN107 alone or in combination with imatinib has acceptable tolerability in patients with imatinib-resistant GIST. These initial data suggest there may be relevant activity of AMN107 alone and in combination with imatinib in imatinib-resistant metastatic GIST patients. [Table: see text]

282 Background: Sunitinib (S) has single-agent activity in patients with advanced urothelial carcinoma (UC). Preclinical studies in UC demonstrate at least additive antitumor activity combining S with gemcitabine (G) or cisplatin (C). Methods: Patients with chemonaïve metastatic UC were enrolled in a multicenter phase II trial with overall response rate (ORR) as the primary endpoint. The initial dosing regimen, based on a phase I trial (Reck, 2010), was G 1000 mg/m2 IV (Days 1 & 8), C 70 mg/m2 IV (Day 1), and S 37.5 mg PO daily (Days 1-14)/each 21-day cycle (up to 6 cycles), followed by S 37.5 mg daily until progression. Results: From December 2008 to August 2009, 15 eligible patients enrolled. Seven of 15 patients discontinued treatment early (median: 3 cycles) due to toxicity, most often due to recurrent neutropenia and thrombocytopenia. Intrapatient dose reductions were required for G (12/15), C (8/15), and S (10/15). Eight of 15 patients experienced serious adverse events. Based on the toxicity profile, enrollment was held and the dosing regimen was revised to G 800 mg/m2 IV (Days 1 and 8), C 60 mg/m2 IV (Day 1), S 37.5 mg PO daily (Days 1-14). From December 2009 to April 2011, 18 additional patients were enrolled. Despite the reduced starting doses, intrapatient dose reductions were required for G (13/18), C (9/18), and S (15/18). The most frequent Grade 3-4 toxicities for both groups were neutropenia (70%), thrombocytopenia (58%), and anemia (30%). Antitumor activity is shown in the Table. Median PFS was 7.9 and median OS was 13.8 months. Conclusions: Combination G+C+S is poorly tolerated and results in activity comparable to historical results with G+C alone.

BackgroundAvelumab, a human anti–PD-L1 monoclonal antibody, has shown a manageable safety profile and antitumor activity in multiple tumor types, including platinum-resistant metastatic or recurrent NSCLC,1 and is approved for patients with locally advanced or metastatic UC who have progressed after ≥1 previous line of platinum-based chemotherapy2 3 and as maintenance treatment for those who have not progressed with platinum-based chemotherapy.4 JAVELIN Medley VEGF (NCT03472560) evaluated the efficacy and safety of avelumab + axitinib, a potent inhibitor of VEGFR 1, 2, and 3, in patients with advanced or metastatic NSCLC or UC.MethodsEligible patients with NSCLC had received ≥1 prior platinum-containing therapy and ≤2 prior lines of systemic therapy for locally advanced or metastatic disease; patients with UC were treatment naive in the locally advanced or metastatic setting and ineligible for cisplatin-containing chemotherapy. Patients were immune checkpoint inhibitor naïve and received avelumab 800 mg intravenously every 2 weeks + axitinib 5 mg orally twice daily. The primary endpoint was confirmed objective response (OR) per investigator assessment (RECIST 1.1). Secondary endpoints included progression-free survival (PFS) and safety. PD-L1 expression was assessed in baseline tumor samples (Ventana SP263 assay). Data have not undergone standard quality checks and are subject to change due to COVID-19–related healthcare burden.ResultsA total of 41 patients with NSCLC and 20 with UC received avelumab + axitinib. The confirmed OR rate was 31.7% (95% CI, 18.1–48.1) in the NSCLC cohort and 10% (95% CI, 1.2–31.7) in the UC cohort (all partial responses); 16 patients (39.0%) and 5 (25.0%) had stable disease, respectively. Responses were observed regardless of PD-L1 expression status. Median PFS was 5.5 months (95% CI, 2.5–7.0) in the NSCLC cohort and 2.3 months (95% CI, 1.8–5.6) in the UC cohort. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 24 patients (58.5%) in the NSCLC cohort; the most common was hypertension (n=7 [17.1%]). Grade ≥3 TRAEs occurred in 9 patients (45.0%) in the UC cohort; the most common were amylase increased, asthenia, decreased appetite, and palmar-plantar erythrodysesthesia syndrome (n=2 [10%] each). One patient in each cohort experienced a TRAE that led to death (gastric perforation and urinary bladder hemorrhage).ConclusionsAvelumab + axitinib showed antitumor activity and a manageable safety profile in patients with advanced or metastatic NSCLC or UC consistent with findings from studies of each drug alone and in combination.Trial RegistrationNCT03472560Ethics ApprovalThe study was approved by each site’s independent ethics committee.ConsentN/AReferencesGulley JL, Rajan A, Spigel DR, et al.

Although Spy DS (SpyGlass DS Direct Visualization System) is considered to be useful for the diagnosis of bile duct strictures and the treatment of bile duct stones, there is limited data to date validating its efficacy. We hence retrospectively evaluated the clinical outcomes of the use of Spy DS in a large number of patients. A total of 183 patients who underwent Spy DS-guided procedures for indeterminate bile duct strictures (n = 93) and bile duct stones (n = 90) were analyzed retrospectively. All patients (93/93) with bile duct strictures successfully underwent visual observation, and 95.7% (89/93) of these patients successfully underwent direct biopsy. The sensitivity, specificity, and overall accuracy were 94.7%, 83.3%, and 90.3%, respectively, for visual impression; 80.9%, 100%, and 89.2%, respectively, for histopathological analysis of a direct biopsy; and 96.5%, 91.7%, and 94.6%, respectively, for visual impression combined with biopsy. Successful visualization of the stones was achieved in 98.9% (89/90) of the patients, and complete stone removal was achieved in 92.2% (83/90) of the patients, with an average of 3.3 procedures. The adverse events rate was 17.5% (32/183; cholangitis in 15 patients, fever the following day in 25, pancreatitis in 1, hemorrhage in 1, and gastrointestinal perforation in 1). No administration of antibiotics before the procedure was found to be a statistically significant risk factor for the development of fever after the procedure (p < 0.01). Spy DS-guided procedures are effective for the diagnosis and treatment of bile duct lesions and can be performed with a low risk of serious adverse events.

Abstract Background Patients with congenital low-flow vascular malformations (capillary (CM), lymphatic (LM), venous (VM) or combined) may have an impaired quality of life (QoL), due to their symptoms, which include pain, swelling, bleeding, thrombosis, and functional impairment. Unfortunately, current treatment methods are challenging and not always successful. Previous studies have shown that the mTOR-inhibitor sirolimus is an effective treatment for these patients. Target levels of 10–15 ng/ml were well tolerated; however, grade three adverse events were observed (ranged 20–40%). Methods A pilot study was performed using a Challenge–Dechallenge–Rechallenge (CDR) design to determine the pharmacodynamics of low target levels of sirolimus (target levels 4–10 ng/ml) in respect of efficacy and adverse events in patients with disabling low-flow vascular malformations without treatment alternatives. The patients received sirolimus over a three-to-six-month period (Challenge), followed by the withdrawal of sirolimus (Dechallenge). If the complaints returned, sirolimus was reintroduced during a twelve month period (Rechallenge). Efficacy was determined on pain (end point of the pilot study) and other symptoms related to the vascular malformation; and adverse events were determined in all phases of the study. Results An improvement in symptoms was seen in 92% (n = 11/12) of patients during the Challenge phase. In the Rechallenge phase, a positive response rate of 78% was found (n = 7/9). These response rates are comparable to those found in the literature despite low target levels of sirolimus. However, less serious adverse events were observed with low dose sirolimus, especially bone marrow toxicity and grade III liver toxicity. Conclusions This pilot using low dose sirolimus showed high efficacy in patients with therapy resistant and disabling low-flow malformation, with a lower incidence of serious adverse events (especially bone marrow toxicity and grade III liver toxicity). This is extremely relevant to patients with low-flow vascular malformation, as current clinical protocols tend to advise lifelong treatment. Trial registration The pilot study was part of a phase III study.

Abstract Background In Japan, following the results of JCOG 9907 trial, neoadjuvant chemotherapy (NAC) and radical surgery has been a standard treatment for Non-T4 cStage II/III esophageal cancer. Since 2009 we have also positioned NAC as standard treatment. We examined treatment outcomes and problems in our institute. Methods From 2009 to 2015, there were 64 patients with non-T4 stage II/III esophageal cancer treated with chemotherapy who are planned to undergo curative surgery. The standard NAC regimen consists of 2 courses of CDDP/5-FU (CF) therapy. As standard surgical procedure, subtotal esophagectomy, cervical anastomosis, three regional lymph node dissection were performed. Results The number of patients was 23/41 cases of cStage II/III respectively. 53 patients (88%) completed two courses of NAC. At the end of first course, NAC was terminated due to adverse events in 4 cases and due to the increasing tendency of tumors in 7 cases. NAC-induced adverse events of grade 3 or higher consists of myelosuppression in 27 cases (42%), appetite loss in 5 cases and so on. Surgery was performed in 61 cases (95%), of which R0 operation in 56 cases (88%), R1 operation in 3 cases and R2 operation in 2 cases. Three patients did not undergo surgery due to progressive disease. There were 7 cases (11%) of postoperative complications of Grade 3 or higher, but there was no in-hospital death. In the histological therapeutic effect, there were 5/41/7/4/3 cases for Grade 0/1a/1b/2/3, respectively. Three-year and five-year overall survival rate of all 64 patients were 68% and 47%.
