TPS546 Background: Changes in the retinoblastoma (Rb) tumor suppressor pathway are believed to contribute to the development of well differentiated neuroendocrine tumors (WDNETs). In the pre-clinical setting, loss or downregulation of proteins that normally inhibit the cyclin dependent kinases Cdk4 and Cdk6 have contributed to NET development. Separately, rigorous investigation of everolimus in WDNETs has demonstrated a survival benefit in this patient (pt) population. Pre-clinical data suggests that the Cdk4/Cdk6 inhibitor LEE011 is synergistically active with everolimus. The aim of this study is to evaluate the efficacy and safety of LEE011 in combination with everolimus in pts with advanced WDNETs of foregut origin (thymic, bronchopulmonary, gastric, duodenal, pancreatic). Methods: This study is a multicenter, non-randomized, open-label phase II clinical trial using a Simon two stage optimal design. Main inclusion criteria include: adult patients with WDNET of foregut origin, low to intermediate grade, unresectable and/or metastatic, disease progression ≤ 12 months prior to enrollment, ECOG 0-1. Between 15 and 43 patients will be enrolled from three sites across the US. LEE011 300mg daily, 3 weeks on and 1 week off, in combination with everolimus 2.5mg daily (final dosing based on phase 1b clinical trial performed in metastatic breast cancer; LEE011X2106) will be administered orally until disease progression, unacceptable toxicity, investigator decision, or pt withdrawal. All enrolled pts will be followed by telephone contact for overall survival until death or consent withdrawal. The primary endpoint, progression free survival, will be assessed based on radiographic review by RECISTv1.1. Main secondary endpoints include establishing the safety of this drug combination in this patient population, objective response rate, clinical benefit rate, and overall survival. Correlative objectives include exploring the effect of this drug combination on biomarkers related to the Rb pathway and/or WDNET pathogenesis. This trial began enrollment in 2/27/2017, with 10 patients enrolled to date. Clinical trial information: NCT03070301.

e16201 Background: Limited systemic treatment options are available for progressive well-differentiated neuroendocrine tumors (NET), also called carcinoid tumors. Given emerging evidence for immunotherapy response in high grade NET including small cell lung cancer, we sought to determine the efficacy of combination immunotherapy with ipilimumab and nivolumab in patients with advanced, progressive, well-differentiated NET in an open label phase II clinical trial. Methods: Eligible patients had well-differentiated, nonfunctional NET of lung, pancreas, or GI origin that had progressed within the past 12 months after at least one line of prior therapy. Patients received nivolumab 240 mg every 2 weeks and ipilimumab 1mg/kg every 6 weeks for up to 2 years. Primary endpoint was objective response rate (ORR) by RECIST v1.1. Using a Simon’s 2-stage design, the study planned to accrue up to 56 patients. Based on published response rates to everolimus of 5%, we hypothesized that this regimen would be considered promising if the true ORR is > 15%. Results: Nine patients were enrolled prior to study closure due to funding, including 6 patients with NET of lung origin, 2 pancreatic, and 1 small bowel (Table). Median age was 71 years. All patients had distant metastatic disease at enrollment, with an average of 2 prior lines of therapy. Four of 9 patients achieved the primary endpoint of confirmed objective response, all of whom have ongoing response with a median duration of 15.4 months. Five of 9 patients, including all 4 responders, experienced immune-related toxicity requiring treatment modification or discontinuation. The trial did not accrue the target of 56 patients, however, objective response in 4 of 9 patients (ORR 44.4%, 90% CI: 16.9-74.9%) excluded the response rate target (15%). Conclusions: The impressive ORR of 44% with a median duration of response exceeding 15 months in this small clinical trial warrants further study of combination CTLA-4 and PD-1 inhibition in previously treated well-differentiated NET. Our ongoing immunologic and genomic correlative analysis in responders and non-responders will help inform future study of immunotherapy in this patient population in need of new systemic therapy approaches.

TPS651 Background: Management of HER2-overexpressing MBC has improved over the past decade. However, pts still develop resistance to currently available HER2-targeted therapies and novel effective treatments are increasingly required as dual targeted combinations are given in early treatment lines already. Current therapies focus on targeting HER2 and do not inhibit all relevant ErbB Family dimers. Afatinib is an oral, irreversible ErbB Family Blocker that inhibits signaling through activated EGFR (ErbB1), HER2 (ErbB2) and ErbB4 receptors and transphosphorylation of ErbB3. Preclinical studies have demonstrated efficacy in T-sensitive and T-resistant human BC xenograft models dependent on ErbB signaling. Efficacy of afatinib in a T-resistant SUM 190 xenograft model has been shown to be increased by addition of IV vinorelbine (V). Afatinib monotherapy has shown promising clinical benefit in 46% of HER2-overexpressing MBC pts who progressed on prior T, with 10% of pts achieving PR. Methods: This open-label Phase II trial (NCT01271725) investigates efficacy and safety of afatinib alone (40 mg/d) followed by afatinib ‘beyond progression’ plus chemotherapy in 120 pts with HER2-overexpressing MBC, who progressed on prior neoadjuvant and/or adjuvant T and/or L. Pts who progress on afatinib monotherapy receive afatinib plus either weekly paclitaxel (P) 80 mg/m2 or V 25 mg/m2. Eligible pts have confirmed HER2-overexpressing BC, stage IV disease measurable by RECIST 1.1, progressed on T and/or L therapy in either neoadjuvant and/or adjuvant setting, are eligible for retreatment with P or V and should not have been pretreated with P (≤12 months) or V, respectively. Exclusion criteria: inadequate cardiac, renal, hepatic and hematological function, pre-existing gastrointestinal dysfunction, rapidly progressing visceral disease, ILD and active brain metastases. The primary endpoint is objective response (OR) and secondary endpoints include best overall response, duration of OR and PFS; safety will be assessed separately for afatinib mono- and combination therapy. Patient enrollment began in May 2011 in ~35 sites and 5 countries.

TPS187 Background: Outcomes for patients with advanced OG cancer remain poor, median overall survival for fit patients treated with platinum and fluoropyrimidine based chemotherapy is less than one year, with second line chemotherapy resulting in a modest (approximately 6 weeks) survival benefit for selected patients. Evidence from NSCLC trials suggests a survival benefit from maintenance treatment following first line chemotherapy. Emerging data also supports the use of immunotherapy in previously treated OG cancer. The PLATFORM study aims to evaluate maintenance therapy in patients with advanced OG cancer. Methods: This is a prospective, open label, multicentre, randomised phase II clinical trial which will recruit at multiple UK cancer centres. Eligible patients are those who have measurable stable disease or better following completion of first line chemotherapy (at least 6 cycles) for locally advanced unresectable or metastatic disease. First line chemotherapy regime should contain a platinum and 5-fluoropyridimine (with trastuzumab if HER2 +), doublet or triplet drug combinations are permitted. Maintenance strategies are split by HER 2 status. For HER2 negative patients these are: Arm A1: surveillance, Arm A2: capecitabine, Arm A3: MEDI 4736 (anti PDL1 inhibitor) and for HER2 positive patients; Arm B1: trastuzumab, Arm B2: in development. Target recruitment is six hundred and sixteen patients, 154 patients will be recruited to each arm, with an interim analysis following recruitment of 61 patients to each arm. An adaptive trial design enables ineffective treatments to be discontinued early, with the opportunity to add novel treatment arms as the trial progresses. Primary endpoint is progression free survival. Secondary endpoints are progression free rate at 3, 6 & 12 months, overall survival, objective response rate by RECIST 1.1, toxicity and analysis of efficacy endpoints according to biomarker status for selected arms. Thirty two patients have been registered for the study with 3 patients randomised, recruitment is ongoing. Clinical trial information: EUDRACT: 2014-002169-30.

1002 Background: P is approved for treatment of HR+/HER2− mBC combined with ET. There is paucity of clinical data of single-agent P in ET resistant pts. Pre-clinical data suggest P may partially reverse endocrine resistance, though this is yet to be tested in pts. Methods: This Phase II, open-label, multicenter study enrolled post-menopausal pts with HR+ HER2− mBC who progressed on 1 or 2 prior ETs. Pts were randomized to P (125 mg/d 3 w on/1 w off) alone or to continue their current ET (aromatase inhibitor or fulvestrant) in combination with P (same schedule as P arm). The primary endpoint was clinical benefit rate (CBR) [complete response (CR), partial response (PR) and stable disease (SD) for > 6 months (mo)]. Secondary endpoints were adverse events (AE) and additional measures of efficacy. A two-stage optimal design assessed treatment activity in each arm assuming activity as CB≥40% (α and β = 10%). Exploratory comparisons were planned for safety and efficacy endpoints. Results: 115 pts were enrolled (ITT population) 58 in the P arm and 57 in the P+ET arm. In both arms, 67% of pts had the study treatment as second line ET, 33% as third line, and about 1/3 of pts also received 1 prior chemotherapy for mBC. CBR was similar in both arms: 54% (95% CI 42 - 67%) with P+ET, and 60% (95% CI 48 -73%) with P alone. Median duration of CB was longer with P+ET (11.5 mo; 95% CI 8.6 – 17.8) than with P (6 mo; 95% CI 3.9 - 9.9) (HR 0.31, 95% CI 0.1 - 0.7, p-value 0.001, exploratory). Objective response rate (ORR; CR, PR) was 11% (95% CI 3 - 19%) and 7% (95% CI 0.4 -13%) with P+ET and P, respectively. PFS was 10.8 mo (95% CI 5.6 - 12.7) with P+ET and 6.5 mo (95% CI 5.4 - 8.5) with P alone (HR 0.69, 95% CI 0.4 - 1.1, p-value 0.13, exploratory). AEs were in line with previous data. Conclusions: Single agent P has clinical activity in ET pre-treated HR+/HER2– mBC pts. The observed increase in PFS and duration of CB with P+ET may suggest that P could reverse resistance to the prior line of ET. Translational studies are ongoing to explore potential biomarkers in this setting. Clinical trial information: NCT02549430.

6017 Background: Metastatic nasopharyngeal cancer (NPC) patients progressed afterstandardtherapy have limited treatment options. Toripalimab, also known as JS001, a humanized IgG4 antibody specific for human PD-1, has been approved for 2nd line treatment of metastatic melanoma in China. Here we report the results from a phase IIstudy in metastatic NPC patients treated with toripalimab.(Clinical trial ID: NCT02915432). Methods: This multi-center, open-label, phase II registration study is designed to evaluate the safety and efficacy of toripalimab in metastaticNPC patients who have failed systemic treatment. Toripalimabis given at 3 mg/kg IV Q2W until disease progression or intolerable toxicity.Tumor PD-L1 expression, plasma EBV DNA level and other biomarkerswill be correlatedwith clinical response. Results: Enrollment of 190chemo-refractory metastatic NPCpatients was completed by Feb 2019 from 17 participating centers. The median age was 46 years, with 89.5% patients received at least 2 lines of prior systemic therapies. Treatment related adverse events (TRAE)occurred in 92% patients, which were mostly grade 1 or 2.Common TRAE includedanemia, hypothyroidism, AST increased, proteinuria, pyrexia, cough, constipation, ALT increased, hypoalbuminemia and pruritus.Grade 3 or higherTRAEoccurred in 25% patients.By the cut-off date of Jan 7 2019, among 135 evaluable patients, 3 complete responses, 31 partial responses and 40 stable diseaseswere observed for an objective response rate (ORR) of 25.2% and a disease control rate of 54.8%. PD-L1 expression results were obtained from 125 patients and 45.6% (57/125) were PD-L1+.PD-L1+ patientsachieved slightly higherORR than PD-L1- patients, 29.8% versus 22.1%. In addition, an average drop of 47-fold plasma EBV DNA copy number was observed in responding patients, which typically proceeded the radiographic identification of clinical benefit. Conclusions: Toripalimab has demonstrated a manageable safety profileand encouraging clinical activity in the largest check-point blockade study in NPC to date. A change in plasma EBV DNA copy number might serve as a predictive marker for favorable clinical response. Patients will be continuously monitored for additional safety and survival readouts. Clinical trial information: NCT02915432.

6032 Background: GLS-010 is a novel fully human anti-PD-1 mAb. Previous Phase I study exhibited favorable result of tolerance, preliminary efficacy and 240mg fixed dose q2w was selected as Recommended Phase II Dose (RP2D). This Phase II clinical trial is aimed to further evaluate the safety and anti-tumor activity of GLS-010 in patients with recurrent or metastatic cervical cancer. Methods: PD-L1 positive (combined positive score (CPS) ≥1) patients with recurrent or metastatic cervical cancer who had received one or more lines of chemotherapy were enrolled and received GLS-010 240mg every 2 weeks. Primary endpoint was the objective response rate (ORR) per RECIST 1.1, secondary endpoints included duration of response (DoR) and safety. Results: From May 16th 2019 to December 24th 2019, 44 pts were enrolled and treated in the study. As of December 24th 2019,the median line of prior systemic chemotherapy was 2(range: 1~4), and 59% (26/44) of pts had received ≥2 previous lines of chemotherapy. The median number of GLS-010 doses was 1.5(range: 1~4). 25 pts received response evaluation per investigator review. With a median follow-up of 2.9 months, 7 of 25 evaluable pts achieved a partial response (PR). The ORR was 28% (95% CI, 12.07-49.39), with 7 pts achieving a PR ( 3 of 7 confirmed), 3 pts achieving stable disease (SD) and 15 pts with progressive disease (PD), 1 of which was assessed as dissociated response with treatment ongoing. Median duration of response had not been reached yet. 33 of 44 patients (75%) experienced one or more treatment-related adverse events (TRAEs) per NCI CTCAE v4.03, most of which were grade 1 or 2. The most common TRAEs were Anaemia (15/44), and 73.3% of them were grade 1 or 2. The most common ≥grade 3 TRAE included Anaemia (4/44). As data cut off, only 1 pt discontinued treatment due to adverse event. Conclusions: GLS-010 showed impressive therapeutic activity and manageable safety profile in Chinese recurrent or metastatic cervical cancer patients. Current evidence support further development of GLS-010 in this and more indications. This trial is still ongoing, and we are looking forward to further results. Clinical trial information: NCT03972722.

We conducted a prospective single-arm open-label phase II clinical trial assessing the safety and efficacy of convalescent plasma in hospitalized COVID-19 patients. Convalescent plasma with sufficient IgG titer (1:320) obtained from recovered donors was administered to adult patients with either severe or critical COVID-19 illness. Primary outcomes were adverse events in association with plasma administration, and hospital mortality. Secondary outcomes included disease progression, recovery, length of stay, and hospital discharge. Of the 38 patients included in the analysis, 24 (63%) recovered and were discharged, and 14 (37%) died. Patients who received convalescent plasma early in the disease course (severe illness group) as compared to the patients that received convalescent plasma later in disease progression (critical illness group) had significantly lower hospital mortality 13% vs 55% (p<0.02) and shorter mean hospital length of stay 15.4 vs 33 days (p<0.01). One patient experienced a transient transfusion reaction. No other adverse effects of convalescent plasma infusion were observed. Our results suggest that convalescent plasma is safe and has the potential for positive impact on clinical outcomes including recovery and survival if given to patients early in the course of COVID-19 disease.

10511 Background: Ixabepilone is an epothilone B analog that has demonstrated efficacy in taxane-sensitive and taxane-resistant MBC. Differing mechanisms of action and minimally overlapping toxicities provide the potential for synergy between ixabepilone and other cytotoxics. Methods: This open-label Phase I/II study was conducted to determine the recommended Phase II (and III) doses of ixabepilone and capecitabine using a 3-hour infusion of ixabepilone given on Day 1 (Schedule A) or a 1-hour infusion of ixabepilone given for 3 consecutive days (Schedule B) in combination with capecitabine given orally on Days 1–14 every 21 days in patients (pts) with MBC previously treated with a taxane and an anthracycline in the adjuvant or metastatic setting. Pts were excluded if they had received >3 prior chemotherapy regimens in the metastatic setting. Tumor response was determined after every 2 cycles. Results from the 62 patients treated with ixabepilone 40 mg/m2 as a 3 hr-infusion and capecitabine 2000 mg/m2 are shown here. Results: 56/62 patients (90%) were aged <65 yrs. 80% of pts had visceral disease and 44% were ER/PR/HER-2 negative. 44% of pts had received ≥2 prior chemotherapies in the metastatic setting. Pts received a median of 4 cycles (range 1–20). The overall response rate was 30% (15/50; 95% CI = 17.9–44.6%) comprised of one (2%) complete response and 14 (28%) partial responses. All 15 of the responders had extensive tumor metastases at baseline. Four of the 15 responders were triple negative for ER/PR/HER-2. The median time to response was 6 weeks (range 5–14 weeks), with most responders achieving an objective response by the end of Cycle 2. The median duration of response was 6.9 months (95% CI = 4.3–9.7 months). Conclusions: The recommended Phase II (and III) doses were 40 mg/m2 ixabepilone (3-hour infusion on Day 1 every 21 days) and 2000 mg/m2 capecitabine (2 doses on Days 1–14 every 21 days). This ixabepilone/capecitabine combination demonstrated promising synergistic antitumor activity and a manageable safety profile in pts with MBC previously treated with a taxane and an anthracycline.

4125 Background: The IGF pathway is thought play an important role in neuroendocrine tumor progression. We therefore investigated AMG 479, a human monocolonal antibody against IGF1-R, in patients with metastatic progressive carcinoid and pancreatic neuroendocrine tumors (NETS). Methods: This open-label phase II study enrolled patients (≥18 yrs) with metastatic low and intermediate-grade carcinoid and pancreatic NETs. Key inclusion criteria included evidence of progressive disease (by RECIST) within 12 months of enrollment, ECOG PS 0-2, and fasting blood sugar <160mg/dL. Prior treatments were allowed, and concurrent somatostatin analog therapy was permitted as long as patients remained on a stable dose. The primary endpoint was objective response rate. Secondary endpoints included overall survival (OS), progression-free survival (PFS), and safety. Results: 60 patients (30 carcinoid, 30 pancreatic NET) were treated with AMG 479 18mg/kg every 3 weeks and 54 patients were evaluable for response. There were no objective responders by RECIST. When best response to therapy was evaluated, 10/27 (37%) evaluable carcinoid patients and 8/26 (31%) evaluable pancreatic NET patients experienced 1-29% tumor shrinkage, while 17/27 (63%) of the carcinoid patients and 15/26 (58%) of the pancreatic NET patients appeared to experience continued tumor growth. Median PFS was 6.3 months (95% CI 4.2-12.6) for the entire cohort; 10.5 months for carcinoid patients and 4.2 months for pancreatic NET patients. The OS rate at 12 months was 70% (55%-81%) for the entire cohort. Median OS has not been reached. Treatment related grade 3/4 AEs were rare and consisted of hyperglycemia (4%), neutropenia (4%), thrombocytopenia (4%) and infusion reaction (1%). Conclusions: While well-tolerated, single-agent AMG 479 was not found to result in major tumor responses among patients with metastatic low-intermediate grade carcinoid or pancreatic NET. Subgroup analysis to identify characteristics of patients who may have benefited from therapy with AMG 479 is ongoing.

4136^ Background: Everolimus has shown antitumor activity in patients (pts) with advanced pancreatic neuroendocrine tumors (NETs). We aimed to assess efficacy and safety of everolimus in combination with octreotide long-acting repeatable (LAR) in patients with well differentiated NETs of gastroenteropancreatic and of lung origin. Methods: We performed a phase II, multicenter trial using a Simon two-stage minmax design. Pts with advanced well differentiated, previously untreated NETs of the gastroenteropancreatic tract and of the lung received octreotide LAR 30 mg every 28 days in conjunction with everolimus 10 mg per day continuously. The primary endpoint was objective response rate (ORR). Results: A total of 50 pts (58% males) were enrolled. The median age was 60.5 years (range 25-76). Primary tumor site was pancreas in 14 (28%), unknown in 14 (28%), lung in 11 (22%), ileum in 9 (18%) and jejunum and duodenum in 2 (4%) of pts. 13 (26%) pts had carcinoid syndrome. The ORR, calculated on the ITT population, was 20.0% (95% CI 8.9-31.1): 2 patients (4%) had a complete response (CR), 8 (16%) a partial response (PR). Thirty-six patients (72%) achieved stable disease (SD). All CR and all PR as well as 91.7% of SD had a duration ≥ 6 months. Clinical benefit (CR+PR+SD) was 92%. At a median follow-up of 277 days, the median time to progression (TTP) was 16.3 months (95% CI 10.7-20.1). Overall survival could not be assessed. Treatment-related adverse events (AEs) were mostly of grade 1 or 2; the only grade 4 AE was mucositis in 1 patient, while grade 3 AEs included skin rash in 1 case, stomatitis in 4 cases (8%) and diarrhea in 11 cases (22%). Conclusions: Everolimus in combination with octreotide LAR has shown to be active and well tolerated in advanced NETs and, in this study, not only in primary pancreatic tumors. Compared to other clinical trials with everolimus in NETs, the observed ORR in this study was higher.
