Esophageal cancer (EC) is among the most frequent and deadly cancers around the world. While esophageal adenocarcinoma (EAC) has one of the fastest-growing incidences amongst cancers in the US, it also has one of the lowest survival rates due to the limited effective treatment options. Fortunately, in the past decade, two targeted therapies and an immunotherapy agent have been approved by the FDA for metastatic EAC and esophageal squamous cell carcinoma (ESCC), with several more currently being considered for approval. In terms of immunotherapies, in July 2019, the FDA approved the PD1 inhibitor pembrolizumab for second-line treatment of PDL1-positive, advanced or metastatic ESCC. Two years before, pembrolizumab had been approved for the third-line treatment of PDL1-positive EAC. The PD1 inhibitor nivolumab, which was found in one study to outperform chemotherapy irrespective of PDL1 status, has yet to secure FDA approval. In terms of targeted therapies, although as many as 90% of EC cases show upregulated EGFR, anti-EGFR therapy has not been shown to improve survival. Ramucirumab, an antibody targeting both VEGF and HER2/neu receptors, has been approved for the treatment of refractory EAC, while the anti-HER2 monoclonal antibody (mAb) trastuzumab has been approved as front-line treatment for HER2-positive cases which account for approximately 20% of ECs. Although these targeted therapies and immunotherapies have resulted in significant improvements in survival for specific patient populations that are positive for certain biomarkers, such as PDL1 and HER2/neu, the survival rates remain low for a large proportion of the metastatic EC patient population, necessitating the development of further targeted treatment options.

Despite advanced diseases continuing to be associated with grim prognoses, the past decade has witnessed the advent of several novel treatment options for cholangiocarcinoma (CCA) patients. In fact, CCA has emerged as a heterogeneous group of malignancies harboring potentially druggable mutations in approximately 50% of cases, and thus, molecularly targeted therapies have been actively explored in this setting. Among these, fibroblast growth factor receptor (FGFR) inhibitors have reported important results, as witnessed by the FDA approval of pemigatinib in previously treated metastatic CCA patients harboring FGFR2 fusion or other rearrangements. Herein, we provide an overview of available evidence on FGFR inhibitors in CCA, especially focusing on the development, pitfalls and challenges of emerging treatments in this setting.

In recent years, there has been a wide range of treatment options for patients with metastatic HER2-positive breast cancer, resulting in  the  highest life expectancy for  these patients among all subtypes. The  addition of  pertuzumab to trastuzumab and docetaxel has been shown to increase overall survival and is therefore recognized as the standard first-line treatment. The most optimal second-line treatment option is trastuzumab emtansine. In  addition, various combinations of  cytostatics and anti HER2 targeting agents can be used. The choice of treatment options in heavily pretreated patients is of great interest. If they have not previously received pertuzumab, is it worth to use it and which combination is the best? One possible option is the combination of eribulin with the dual anti-HER2 blockade with trastuzumab and pertuzumab. Eribulin is an anti-microtubule agent that irreversibly blocks mitosis. In addition, it has non-mitotic effects – in vivo and in vitro experiments demonstrated its ability to restore normal tumor vascularization, reduce the area of hypoxia and, as a consequence, decrease tumor cells migration and invasion. This article represents a clinical case of the use of eribulin with double anti-HER2 blockade in the 6th line of treatment in a patient with metastatic HER2-positive breast cancer. Long-term control of the disease (within 2 years) with a satisfactory quality of life has been demonstrated.

Systemic treatment options for advanced renal cell carcinoma (RCC) have expanded considerably with the development of targeted therapies. Clear cell RCC commonly features mutation or inactivation of the von Hippel-Lindau gene and resultant overexpression of vascular endothelial growth factor (VEGF). The first drug to validate VEGF as a target in the treatment of clear cell RCC was the monoclonal antibody bevacizumab. Since then, anti-VEGF receptor therapy with multitargeted kinase inhibitors also has shown substantial efficacy. Sunitinib is now a standard first-line therapy for advanced disease and sorafenib is among the second-line treatment options. Other kinase inhibitors are in development. Mammalian target of rapamycin (mTOR) is a second validated therapeutic target as the mTOR inhibitor temsirolimus has been shown to prolong survival in first-line treatment of poor prognosis RCC of all histologies. Everolimus is an oral mTOR inhibitor and has been shown to prolong progression-free survival when used in second-line treatment. Non-clear cell and sarcomatoid RCC are both underrepresented in completed trials but are the subject of active research. Ongoing and planned studies will also evaluate the use of combinations of targeted agents, a strategy that is not advisable outside of clinical trials. Finally, postnephrectomy adjuvant treatment with targeted agents is not yet standard but is under investigation in phase III trials.

Survival for patients with unresectable advanced or recurrent gastric cancer (GC) remains poor and the historical lack of evidence-based therapeutic options after second-line therapy is reflected in current clinical guidelines for this condition. Despite uncertainty about optimal therapeutic strategies, further treatment is appropriate for some patients after failure of second line and may prolong survival. This approach has been reported in clinical trials and is becoming more common in real-world clinical settings. Several prognostic factors may increase the likelihood that a patient will be eligible for treatment in the third-line setting, including geographic location, status at diagnosis and response to treatment. There has been little progress over the last decade until the results from two large phase III randomized controlled trials completed in the last year: the ATTRACTION-2 trial with the programmed cell death-1 (PD-1) inhibitor, nivolumab, in an Asian population; and the TAGS trial with the oral chemotherapy trifluridine/tipiracil in a global population. Both ATTRACTION-2 and TAGS reported positive results in third-line treatment in advanced GC in specific patient groups. A further recently reported study, KEYNOTE-059, which was a single-arm phase II trial of the PD-1 inhibitor pembrolizumab in a mainly non-Asian population, has provided evidence supporting the use of this immunotherapy in patients with advanced GC. As further third-line options become available, more GC patients are expected to benefit from an individualized evidence-based approach to later-line therapy, with a common goal of extending survival and improving outcomes for their refractory disease.

Abstract Relapsed acute lymphoblastic leukemia (ALL) has remained challenging to treat in children, with survival rates lagging well behind those observed at initial diagnosis. Although there have been some improvements in outcomes over the past few decades, only ∼50% of children with first relapse of ALL survive long term, and outcomes are much worse with second or later relapses. Recurrences that occur within 3 years of diagnosis and any T-ALL relapses are particularly difficult to salvage. Until recently, treatment options were limited to intensive cytotoxic chemotherapy with or without site-directed radiotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). In the past decade, several promising immunotherapeutics have been developed, changing the treatment landscape for children with relapsed ALL. Current research in this field is focusing on how to best incorporate immunotherapeutics into salvage regimens and investigate long-term survival and side effects, and when these might replace HSCT. As more knowledge is gained about the biology of relapse through comprehensive genomic profiling, incorporation of molecularly targeted therapies is another area of active investigation. These advances in treatment offer real promise for less toxic and more effective therapy for children with relapsed ALL, and we present several cases highlighting contemporary treatment decision-making.

4591 Background: Cholangiocarcinoma (CCA) is the most common biliary tract malignancy with an estimated incidence of 8,000–10,000 patients/year in the US. Chemotherapy is the most common second-line treatment with reported outcomes in patients with CCA. Response rates of < 10% and median progression-free survival (PFS) times of ~3–4 months have been reported with second-line chemotherapy regimens, including FOLFOX in the ABC-06 trial. Fibroblast growth factor receptor 2 ( FGFR2) fusions occur in 13–17% of CCA and multiple targeted agents are in development for patients with FGFR2 fusions. To date, the outcome of patients with CCA and FGFR2 fusions receiving standard second-line chemotherapy is unknown. Methods: Patients with advanced CCA and FGFR2 fusions after prior treatment with gemcitabine-based chemotherapy were enrolled in a single-arm phase 2 study (NCT02150967) and received the FGFR1–3 selective TKI infigratinib (previously BGJ398) 125 mg orally qd on d1–21, cycles repeated q28 days until unacceptable toxicity, disease progression, investigator discretion, or withdrawal of consent. A retrospective analysis of a subset of patients who received infigratinib as third- or later-line treatment was performed. Investigator-assessed PFS and best overall response (BOR, per RECIST 1.1) following second-line chemotherapy (pre-infigratinib) and third-line or later-line infigratinib were calculated. Results: Of the 71 patients (44 women; median age 53 years) with FGFR2 fusions enrolled at the time of analysis (datacut 8 August 2018), 37 (52%) were included in this retrospective analysis. Median PFS with standard second-line chemotherapy was 4.63 months (95% CI 2.69–7.16) compared with 6.77 months (95% CI 3.94–7.79) for third- and later-line infigratinib. BOR for second-line chemotherapy was 5.4% (95% CI 0.7–18.2) compared with 21.6% for third- and later-line infigratinib (95% CI 9.8–38.2). Conclusions: Outcomes from second-line chemotherapy in patients with CCA and FGFR2 fusions were similar to those reported in the literature for all patients with CCA regardless of genomic status and remain dismal. Infigratinib administered as third- and later-line treatment resulted in a meaningful PFS and ORR benefit in patients with CCA and FGFR2 fusions. Clinical trial information: NCT02150967 .

InterventionsTargeted therapies have been proven to provide clinical benefits to patients with metastatic non-small cell lung cancer (NSCLC). Gefitinib was initially approved and reimbursed as a third-line therapy for patients with advanced NSCLC by the Taiwan National Health Insurance (NHI) in 2004; subsequently it became a second-line therapy (in 2007) and further a first-line therapy (in 2011) for patients with epidermal growth factor receptor mutation-positive advanced NSCLC. Another targeted therapy, erlotinib, was initially approved as a third-line therapy in 2007, and it became a second-line therapy in 2008.ObjectivesThis study is aimed towards an exploration of the impacts of the Taiwan NHI reimbursement policies (removing reimbursement restrictions) related to accessibility of targeted therapies.SettingWe retrieved 2004–2013 claims data for all patients with lung cancer diagnoses from the NHI Research Database.Design and outcome measuresUsing an interrupted time series design and segmented regression, we estimated changes in the monthly prescribing rate by patient number and market shares by cost following each modification of the reimbursement policy for gefitinib and erlotinib for NSCLC treatment.ResultsTotally 92 220 patients with NSCLC were identified. The prescribing rate of the targeted therapies increased by 15.58%, decreased by 10.98% and increased by 6.31% following the introduction of gefitinib as a second-line treatment in 2007, erlotinib as a second-line treatment in 2008 and gefitinib as as first line treatment in 2011, respectively. The average time to prescription reduced by 65.84% and 41.59% following coverage of erlotinib by insurance and gefitinib/erlotinib as second-line treatments in 2007–2008 and following gefitinib as the first-line treatment in 2011.ConclusionsThe changes in reimbursement policies had a significant impact on the accessibility of targeted therapies for NSCLC treatment. Removing reimbursement restrictions can significantly increase the level and the speed of drug accessibility.

About 20% of all breast cancer patients have a human epidermal growth factor receptor 2 (HER2)-positive breast tumor. This entity underwent an impressive change in prognosis, with notable improvement of progression-free survival and overall survival. Due to more aggressive tumors and no specific therapy, HER2 overexpression was historically seen as a negative prognostic marker, with worse prognosis and increased risk of recurrent disease. Trastuzumab, the first anti-HER2 antibody, revolutionized the systemic therapy options in HER2-positive breast cancer and initiated several targeted therapies and more personalized treatment strategies. Over the years, multiple HER2-targeting drugs stepped into clinical practice, for the curative as well as the metastatic situation. This review summarizes the targeted treatment options in HER2-positive breast cancer and their current impact in the clinical routine. Results of the most outstanding trials in HER2-targeted therapies and important ongoing trials are subsequently described for an up-to-date overview.
