TPS472 Background: Adenocarcinoma of esophagus (EAC) and GEJ is the fastest rising cancer in the US. The outcomes are extremely poor with median overall survival (OS) being 12 mo in patients (pts) with metastatic disease. The standard first line treatment for metastatic EAC is platinum-based regimen with median progression free survival (PFS) of 6 mo. Second line options are associated with limited efficacy. An analysis of TCGA has shown 40% of EAC harboring abnormalities in HR genes, most likely resulting from chronic acid reflux induced DNA damage. HR dysregulation is commonly associated with high LOH. Sensitivity to PARP inhibition has been shown to be a surrogate for HR defects or BRCAness phenotype. Clinically PARP inhibitors have shown activity in HR defective prostate and ovarian cancers. These findings provide the basis for this study. Methods: Pts with metastatic esophageal/GEJ/proximal gastric adenocarcinoma, previously treated with 1 line of platinum containing chemotherapy, and harboring high LOH and/or deleterious alteration(s) in HR genes ( BRCA1/2, PALB2, ATM, BARD1, BRIP1, CDK12, CHEK2, FANCA, RAD51, RAD51B, RAD51C, RAD51D, RAD54L, NBN, ARID1A, GEN1) are eligible for this study. Pts can be prescreened at the time of diagnosis of locally advanced or metastatic disease by genomic analysis of the most recent available tumor tissue. Pts will receive oral niraparib until disease progression or unacceptable toxicity. Primary objective is response rate (RR). Secondary objectives are safety and tolerability, progression free survival (PFS), and disease control rate (DCR). Exploratory objectives include correlation between high LOH and response to niraparib, mechanisms of resistance to PARP inhibition, EZH2 expression and its correlation with response and resistance to PARP inhibition, and analysis of germline HR gene mutations and correlation with response to niraparib. Estimated sample size is 43. The study has recently opened to accrual at Indiana University with intended collaboration with 2 additional sites. Clinical trial information: NCT03840967.

19505 Background: The treatment of gastrointestinal stromal tumors has been revolutionised by the advent of Imatinib, a specific tyrosine kinase inhibitor. Post operative local and metastatic recurrences of this tumor have been effectively managed by Imatinib. Here we present our experience of Imatinib in recurrent locally advanced/metastatic gastrointestinal stromal tumors (GIST). Methods: From Nov 2001 to Sep 2005, 33 patients with metastatic and / or locally advanced inoperable CD-117 positive GIST were offered imatinib mesylate therapy at 400 mg/day p.o. A total of 21 patients were evaluable for tumor response. Follow up period ranged from 4 months to 38 months with median follow up period being 18 months. Median age is 58 yrs, M:F ratio is 6:4. ECOG performance status was 0–1 in 70% (23 patients) and 2 in 30% (10 patients). 70% patients had post surgery recurrence. 2 patients (6%) had received adjuvant chemotherapy prior to recurrence. 30% (10 patients) had local recurrence, 40% (13 patients) had metastatic disease while 30% (10 patients) had local recurrence as well as metastatic disease. Results: Response evaluation was done by RECIST criteria. 15% (5 patient) showed CR while PR rates were 30% (10 patients). The overall major response (CR+PR) was 45%. The overall progression free survival was as high as 80%. All the patients who had a progression free survival also had a significant improvement in quality of life. Conclusions: Imatinib mesylate therapy shows significant survival benefits in locally advanced inoperable/metatstatic gastrointestinal stromal tumors. It will be a very long time before PET scan for evaluation and follow up becomes feasible in developing country setting. No significant financial relationships to disclose.

101 Background: Immune checkpoint inhibitors (ICKi) are highly effective for MSI/dMMR mCRC pts. RECIST1.1 criteria are reported to underestimate response to ICKi. The GERCOR NIPICOL phase II study aimed to evaluate disease control rate (DCR) using RECIST1.1 and iRECIST for MSI/dMMR mCRC pts treated with nivolumab (NIVO) and ipilimumab (IPI). Methods: MSI/dMMR mCRC pts previously treated with fluoropyrimidines (FP), oxaliplatin (OX) and irinotecan (IRI) ± targeted therapies received NIVO 3 mg/kg + IPI 1 mg/kg Q3W for 4 cycles then NIVO 3 mg/kg Q2W until progression or a maximum of 20 cycles. CT-scan tumor assessments were done every 6 weeks during 24 weeks and then every 12 weeks. Primary objective was DCR at 12 weeks (12wDCR) according to RECIST1.1 and iRECIST by central review. Response rates and progression-free survival (PFS) by central review were secondary objectives. A one-stage Fleming design was used with a targeted improvement of 12wDCR from 70% to 85%. Results: Of 57 pts included between Dec 2017 and Nov 2018, 43.9% had received ≥ 3 prior lines including FP (100%), OX (100%), IRI (95.5%), antiangiogenics (57.9%) and anti-EGFRs (45.6%). 17.5% of pts had BRAF mutation and 27.5% Lynch syndrome. Grade 3-4 treatment-related adverse events were reported in 49.1% of pts, mainly hepatitis (12.3%). 12wDCR was 86.0% and 87.7% using RECIST1.1 and iRECIST respectively, with only 1 pseudo-progression (1.8%) observed during the first 12 weeks, and one later. Kappa coefficient between RECIST and iRECIST 12wDCR was 0.92 (95%CI 0.77-1.0). Best observed responses with RECIST1.1/iRECIST were: 2/2 complete responses (3.5/3.5%), 19/19 partial responses (33.3/33.3%), 30/31 stable diseases (52.6/54.4%) and 3/2 disease progressions (5.3/3.5%), with 3 pts not evaluable (cancer-related deaths before first evaluation). Conclusions: Combination of NIVO and IPI in MSI/dMMR mCRC is associated with a low frequency of pseudo-progression and high DCR rate. PFS will be evaluated in Dec 2019, with all pts having completed the predefined 1-year of ICKi therapy. Clinical trial information: NCT033501260.

6045 Background: SAHA is a small molecule inhibitor of histone deacetylases (HDAC). Based on confirmed responses noted in 2 ACC patients treated with SAHA at our institution; we initiated this phase II trial. Methods: Patients with LA, recurrent or metastatic ACC and adequate organ function were eligible. Any prior number of chemotherapy regimens was allowed. Tumor tissue and blood were collected for correlative studies. SAHA was administered orally 400 mg daily for 28 days. The primary objective was to evaluate response rate (RR). Secondary endpoints included: time to tumor response (TTR); response duration (RD); progression-free survival (PFS); overall survival (OS); and adverse events (AE). 29 evaluable patients were needed in a Simon 2-stage optimal design to distinguish RR of at most 5% vs. at least 20%, with alpha = 0.15 and power = 0.90. Results: 30 evaluable patients (overenrolled by 1) were accrued from at 5 different centers between August 2010 and June 2012. Median follow up among the censored patients is 3.8 months for PFS, and 7.2 months for OS. 19 patients were female, 24 were Caucasian, median age was 53 years (range 21-73); 21 patients had a performance status of 1; 20 patients were chemo-naïve. The median number of cycles completed was 5 (range 1-27+). Lymphopenia (n=5), hypertension (n=3), oral pain (n=2), thromboembolic events (n=2) and fatigue (n=2) were the only grade 3 AEs that occurred in more than 1 patient. 5 patients were dose reduced due to AEs. At the time of data cut-off, 9/30/2012, 1 patient with lung metastasis had a PR, with RD of 11.2+ months. TTR was 7.7 months. SD was the best response in 25 patients. Median PFS is 12.7 months (90% confidence interval lower limit: 3.7 months). Median OS has not been reached. There were 6 patients with PFS > 1 year. The correlative studies results will be presented. Conclusions: SAHA shows promise in the treatment of ACC. We are awaiting genomic analysis of the tumors to study the basis of clinical benefit (PR and SD) of SAHA in ACC. Future drug combination studies in ACC are being considered focusing on the epigenetic mechanism of SAHA. Supported by 5U01CA062487/19. Clinical trial information: NCT01175980.

Abstract Background Prostate cancer (PC) is a leading cause of death in older men. Androgen deprivation therapy (ADT) is considered the standard-of-care for men with locally advanced disease. However, continuous androgen ablation is associated with acute and long-term adverse effects and most patients will eventually develop castration-resistant PC (CRPC). The recent approval of three, second-generation androgen receptor inhibitors (ARIs), apalutamide, enzalutamide, and darolutamide, has transformed the treatment landscape of PC. Treatment with these second-generation ARIs have produced positive trends in metastasis-free survival, progression-free survival, and overall survival. For patients with non-metastatic CRPC, who are mainly asymptomatic from their disease, maintaining quality of life is a major objective when prescribing therapy. Polypharmacy for age-related comorbidities also is common in this population and may increase the potential for drug–drug interactions (DDIs). Method This review summarizes the multiple factors that may contribute to the therapeutic burden of patients with CRPC, including the interplay between age, comorbidities, concomitant medications, the use of ARIs, and financial distress. Conclusions As the treatment landscape in PC continues to rapidly evolve, consideration must be given to the balance between therapeutic benefits and potential treatment-emergent adverse events that may be further complicated by DDIs with concomitant medications. Patient-centered communication is a crucial aspect of alleviating this burden, and healthcare professionals (HCPs) may benefit from training in effective patient communication. HCPs should closely and frequently monitor patient treatment responses, in order to better understand symptom onset and exacerbation. Patients also should be encouraged to participate in exercise programs, and health information and support groups, which may assist them in preventing or mitigating certain determinants of the therapeutic burden associated with PC and its management.

PURPOSE: To investigate whether the addition of cisplatin (CDDP) to hyperfractionation (Hfx) radiation therapy (RT) offers an advantage over the same Hfx RT given alone in locally advanced (stages III and IV) squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: One hundred thirty patients were randomized to receive either Hfx RT alone to a tumor dose of 77 Gy in 70 fractions in 35 treatment days over 7 weeks (group I, n = 65) or the same Hfx RT and concurrent low-dose (6 mg/m2) daily CDDP (group II, n = 65). RESULTS: Hfx RT/chemotherapy offered significantly higher survival rates than Hfx RT alone (68% v 49% at 2 years and 46% v 25% at 5 years; P = .0075). It also offered higher progression-free survival (46% v 25% at 5 years; P = .0068), higher locoregional progression-free survival (LRPFS) (50% v 36% at 5 years; P = .041), and higher distant metastasis-free survival (DMFS) (86% v 57% at 5 years; P = .0013). However, there was no difference between the two treatment groups in the incidence of either acute or late high-grade RT-induced toxicity. Hematologic high-grade toxicity was more frequent in group II patients. CONCLUSION: As compared with Hfx RT alone, Hfx RT and concurrent low-dose daily CDDP offered a survival advantage, as well as improved LRPFS and DMFS.

Purpose The benefit of salvage chemotherapy is modest in metastatic urothelial cancer. We conducted a randomized, noncomparative phase II study to measure the efficacy of cetuximab with or without paclitaxel in patients with previously treated urothelial cancer. Patients and Methods Patients with metastatic urothelial cancer who received one line of chemotherapy in the perioperative or metastatic setting were randomly assigned to 4-week cycles of cetuximab 250 mg/m2 with or without paclitaxel 80 mg/m2 per week. We used early progression as an indicator of futility. Either arm would close if seven of the initial 15 patients in that arm progressed at the first disease evaluation at 8 weeks. Results We enrolled 39 evaluable patients. The single-agent cetuximab arm closed after nine of the first 11 patients progressed by 8 weeks. The combination arm completed the full accrual of 28 patients, of whom 22 patients (78.5%) had visceral disease. Twelve of 28 patients had progression-free survival greater than 16 weeks. The overall response rate was 25% (95% CI, 11% to 45%; three complete responses and four partial responses). The median progression-free survival was 16.4 weeks (95% CI, 12 to 25.1 weeks), and the median overall survival was 42 weeks (95% CI, 30.4 to 78 weeks). Treatment-related grade 3 and 4 adverse events that occurred in at least two patients were rash (six cases), fatigue (five cases), and low magnesium (three cases). Conclusion Although it had limited activity as a single agent, cetuximab appears to augment the antitumor activity of paclitaxel in previously treated urothelial cancers. The cetuximab and paclitaxel combination merits additional study to establish its role in the treatment of urothelial cancers.

278 Background: Tivozanib (T) is a potent and highly selective VEGF receptor (R) tyrosine kinase inhibitor in clinical development for RCC. Axitinib is also a potent and selective VEGF-R inhibitor now commonly part of front-line aRCC treatment. The activity of T after axitinib has not been previously defined. The activity of T after prior therapy types including axitinib is of clinical relevance. Methods: The pivotal TIVO-3 study enrolled subjects with mRCC who failed 2 or 3 prior systemic regimens, one of which included a VEGFR TKI, stratified by IMDC risk category and type of prior therapy (two TKIs; TKI plus checkpoint; TKI + other) then randomized in a 1:1 ratio to T or S. The primary objective of the overall trial was to compare progression free survival (PFS) by blinded independent radiological review. Patients with prior axitinib received as monotherapy in the second or third line setting and other predefined subgroups were reviewed for outcome with T. Results: Patients treated with T after prior axitinib had a PFS of 5.5 months and an ORR of 13% compared to 3.7 months and 8% for patients treated with S. Other subgroups are presented in the table below. Clinical trial information: NCT02627963 . Conclusions: Tivozanib improved PFS vs. sorafenib in patients who have progressed after multiple VEGFR-TKIs, including patients with prior second or third line axitinib treatment. These results suggest differential activity from tivozanib and axitinib despite both being potent and selective VEGF-R inhibitors. [Table: see text]

11516 Background: Eribulin and gemcitabine have shown encouraging efficacy in soft-tissue sarcoma (STS) as a monotherapy. Here, we evaluated the activity and safety of combined use of eribulin and gemcitabine in two most common histologic types of STS, liposarcoma and leiomyosarcoma. Methods: In this non-randomized, multi-center phase 2 study, patients were included if they had progressive disease after one or two prior chemotherapy including doxorubicin. Patient were given eribulin 1.4 mg/m2 and gemcitabine 1,000 mg/m2 on day1 and day 8 every 3 weeks. The primary endpoint was progression-free survival rate at 12 weeks (PFSR12wks) with null and alternative hypothesis of PFSR12wks≤20.0% and ≥40.0%, respectively. Results: Of 37 patients included, 22 had leiomyosarcoma, and 15 had liposarcoma. At 12-weeks after treatment, 16 and (72.7%) 11 (73.3%) patients in leiomyosarcoma and liposarcoma were progression-free. Overall PFSR12wks was 73.0%, satisfying the primary endpoint. Objective response rate, disease control rate, median progression-free survival, and median overall survival were 16.2%, 78.4%, 23.9 weeks, and 88.9 weeks, without any statistical differences according to histologic subtypes. No new safety signals and treatment-related death were observed. Conclusions: Eribulin and gemcitabine showed promising activity and manageable safety profile in patients with STS of liposarcoma and leiomyosarcoma histology. Updated outcomes for ongoing patients will be presented. Clinical trial information: NCT03810976.

361 Background: Primitive neuroectodermal tumours (PNET) of the kidney are rare tumours with aggressive behaviour. This study was conducted to review the diagnosis and management of patients with renal PNET at our centre. Methods: This was a retrospective study conducted at a tertiary cancer care centre in Mumbai, India. The demographic and clinical data of 17 patients treated by the uro-oncology services were retrieved from electronic medical records. Descriptive analysis was performed for baseline characteristics.Overall & progression-free survival was determined using the Kaplan Meier method. Cox regression was used for multivariate analysis. Results: There were 12 male and 5 female patients in this cohort with a median age of 27 years. At diagnosis 2 patients had metastatic disease and 15 patients had non-metastatic disease. Median follow up in this cohort was 22 months (range 2-30 months). Presenting complaints were hematuria, abdominal pain, flank pain, fever, bone pain, and incidentally detected renal mass. All patients were Mic -2 positive and 13 were FLI-1 positive on immunohistochemistry. Fourteen patients underwent radical nephrectomy. One (5.9%) patient received both neoadjuvant and adjuvant chemotherapy, 8 (47.1%) received adjuvant and 2 (11.8%) received palliative chemotherapy upfront. Eight patients received adjuvant radiation to the renal bed.There was disease progression in12 patients,10 of 15 patients with non metastatic disease at diagnosis eventually developed metastasis.The median progression free survival (PFS) was 10.55 months.The pathological feature that was associated with a shorter PFS was tumor size ⩾10 cm(p = 0.044).The median overall survival was 20.04 months (95% CI 9.49 -not reached). The presence of metastasis and treatment received significantly impacted overall survival (OS). Median OS in patients with non-metastatic disease was not reached versus 14.1 months in those with metastatic disease (p = .019).The median OS in patients treated with multimodality approach was 20.11 months. Patients did not undergo surgery had a median OS of 5.45 months (p < .001) and those who did not receive any chemotherapy had a median OS of 4.57 months (p = .024).Thus, patients who received multimodality treatment had better outcomes. Conclusions: PNET kidney is an aggressive tumor which should be treated with a multimodality approach. Tumor size ⩾10 cm was an adverse prognostic factor.
