Project description:BACKGROUND & AIMS:Gemcitabine plus cisplatin (GC) remains the standard, frontline therapy for advanced biliary tract cancer (ABTC). The JCOG1113 study suggested that gemcitabine plus S-1 (GS) had noninferior median overall survival and comparable incidence of significant neutropenia as compared to GC treatments. This study evaluates the efficacy and safety of a modified GS regimen. METHODS:The eligible patients with chemonaive, measurable ABTC received 800 mg/m2 of gemcitabine on day 1 and 80 mg/m2 /day of S-1 (80/100/120 mg for patients with body surface <1.25/ ?1.25 and <1.5/ ?1.5 m2 respectively). The primary endpoint was the 12-week disease control rate (12-week DCR: objective response and stable disease ? 12 weeks). Per the p0 = 40% and p1 = 60% (?/? = 0.05/0.2) assumption, Simon's optimal two-stage design indicated 12-week DCR in ? 24 of 46 evaluable patients for significant activity. Tumour responses were assessed every 6 weeks. RESULTS:Fifty-one patients were enrolled and most of them had intrahepatic cholangiocarcinoma (64.7%), metastatic disease (84.3%) and disease-related symptoms (82.4%). On intention-to-treat analysis, 11 (21.6%) patients showed partial response, whereas 21 (41.2%) showed stable disease ? 12 weeks. The progression-free and overall survival were 5.4 months (95% confidence interval [CI]: 3.5-7.0), and 12.7 months (95% CI: 6.1-15.6) respectively. The study met its primary endpoint with a 12-week DCR of 69.6% in 46 evaluable patients. Grade 3/4 treatment-related adverse eventsoccurred in < 6% of patients of all individual items. The mean dose intensities of S-1 and gemcitabine were 87.1% and 92.5% respectively. CONCLUSIONS:Modified GS showed moderate efficacy with a favourable safety profile in ABTC patients, thus mandating further assessment. ClinicalTrials.gov number: NCT02425137.

Project description:BackgroundPatients with advanced biliary tract cancer who progress on first-line therapy have limited treatment options. The TreeTopp study assessed varlitinib, a reversible small molecule pan-human epidermal growth factor receptor inhibitor, plus capecitabine in previously treated advanced biliary tract cancer.Patients and methodsThis global, double-blind, randomized, placebo-controlled phase II study enrolled patients with confirmed unresectable or metastatic biliary tract cancer and disease progression after one prior line of gemcitabine-containing chemotherapy. Patients received oral varlitinib 300 mg or placebo twice daily (b.i.d.) for 21 days, plus oral capecitabine 1000 mg/m2 b.i.d. on days 1-14, in 21-day treatment cycles. Co-primary endpoints were objective response rate and progression-free survival (PFS) according to RECIST v1.1 by Independent Central Review.ResultsIn total, 127 patients received varlitinib plus capecitabine (n = 64) or placebo plus capecitabine (n = 63). The objective response rate was 9.4% with varlitinib plus capecitabine versus 4.8% with capecitabine alone (odds ratio 2.28; P = 0.42). Median PFS was 2.83 versus 2.79 months [hazard ratio (HR), 0.90; 95% confidence interval (CI), 0.60-1.37; P = 0.63] and overall survival was 7.8 versus 7.5 months (HR, 1.11; 95% CI, 0.69-1.79; P = 0.66), respectively. In a subgroup analysis, the addition of varlitinib appeared to provide a PFS benefit in female patients (median, 4.1 versus 2.8 months; HR, 0.59; 95% CI, 0.28-1.23) and those with gallbladder cancer (median, 2.9 versus 1.6 months; HR, 0.55; 95% CI, 0.26-1.19). Grade ≥3 treatment-emergent adverse events were reported in 65.6% of patients receiving varlitinib plus capecitabine versus 58.7% of those receiving capecitabine alone.ConclusionsIn patients with advanced biliary tract cancer, second-line treatment with varlitinib plus capecitabine was well tolerated but did not improve efficacy versus capecitabine alone. A PFS benefit was suggested in female patients and those with gallbladder cancer.

Project description:Lessons learnedTrifluridine/tipiracil (FTD/TPI) shows promising antitumor activity in heavily pretreated patients with advanced biliary tract carcinoma, including patients with 5-fluorouracil refractory tumors. FTD/TPI has an acceptable safety profile and should be studied further in patients with advanced biliary tract carcinoma after progression on standard first-line therapy.BackgroundPatients with advanced biliary tract carcinoma (BTC) refractory to first-line therapy lack an established second-line option. Trifluridine/tipiracil (FTD/TPI) has activity in both fluoropyrimidine-sensitive and -resistant tumors, which led us to conduct a single arm phase II trial to evaluate the safety and efficacy of FTD/TPI for patients previously treated for advanced BTC.MethodsPatients with advanced BTC previously treated with at least one line of chemotherapy were enrolled and treated with FTD/TPI until disease progression or unacceptable toxicity. The primary endpoint target was to have at least 6 patients who were progression free and alive at 16 weeks among 25 evaluable patients. Secondary endpoints included overall survival (OS), overall response rate (ORR), progression-free survival (PFS), and toxicity.ResultsOf 27 evaluable patients, 59.3% received at least three prior lines of therapy, and 81.5% had previous exposure to fluoropyrimidine. Eight (32%, 95% confidence interval [CI], 14.9%-53.5%) patients were progression free at 16 weeks in the primary analysis population (n = 25), which met the predefined efficacy criteria. Median PFS and OS were 3.8 (95% CI, 2-5.8 months) and 6.1 (95% CI, 4.4-11.4 months) months, respectively. No objective responses were seen. There were no unexpected safety signals noted.ConclusionFTD/TPI demonstrated promising antitumor activity, with acceptable toxicity, in heavily pretreated patients with advanced BTC.

Project description:Only recently has a standard chemotherapy regimen, gemcitabine plus cisplatin, been established for advanced biliary tract cancers (BTCs) based on a phase III randomized study. The aim of this phase II single-institution trial was to assess the efficacy and safety of gemcitabine combined with carboplatin in the first-line treatment of patients with advanced BTCs.Patients with histologically proven BTCs, including cholangiocarcinoma or gallbladder and ampullary carcinomas, were treated with a maximum of nine cycles of intravenous (i.v.) gemcitabine at 1000 mg/m(2) over 30 min on days 1 and 8 with i.v. carboplatin dosed at an area-under-the-curve (AUC) of 5 over 60 min on day 1 of a 21-day cycle.A total of 48 patients with advanced BTCs (35 cholangiocarcinoma, 12 gallbladder and 1 ampullary cancer) were enrolled. A median of four cycles were administered (range: 1-9). The overall response rate for evaluable patients was 31.1%. Median progression-free survival, overall survival and 6-month survival rates are 7.8 months, 10.6 months and 85.4%, respectively. The most common grade 3-4 toxicities include neutropenia and thrombocytopenia. Grade 3 or 4 non-haematological toxicities were rare.Gemcitabine combined with carboplatin has activity against advanced BTCs. Our results are comparable to other gemcitabine-platinum or gemcitabine-fluoropyrimidine combinations in advanced BTCs.

Project description:ImportanceCurrently, there is no established second-line systemic treatment for biliary tract cancer (BTC). Preclinical data have demonstrated that the presence of tumor-infiltrating CD8 T cells and programmed cell death 1 ligand 1-expressing tumor cells in the tumor microenvironment of BTC supports the rationale of using programmed cell death 1 protein blockade immunotherapy in BTC.ObjectiveTo evaluate anticancer activity of nivolumab in patients with advanced refractory BTC.Design, setting, and participantsIn this single-group, multicenter phase 2 study of nivolumab, 54 patients with histologically confirmed BTC whose disease progressed while undergoing treatment with at least 1 line but no more than 3 lines of systemic therapy were enrolled between October 5, 2016, and December 26, 2018. Analysis was performed on an intention-to-treat basis.InterventionsNivolumab, 240 mg, was delivered intravenously every 2 weeks for 16 weeks, and then 480 mg was delivered intravenously every 4 weeks until disease progression or unacceptable toxic effects occurred.Main outcomes and measuresThe primary end point was investigator-assessed objective response rate, and the secondary end points were progression-free survival, overall survival, and incidence of adverse events.ResultsA total of 54 patients (27 men and 27 women; median age, 65 years [range, 28-86 years]) enrolled, and 46 (22 men and 24 women; median age, 65 years [range, 28-86 years]) were examined for objective response with radiologic imaging. The investigator-assessed objective response rate was 22% (10 of 46), including 1 unconfirmed partial response, with a disease control rate of 59% (27 of 46). Central independent review found an objective response rate of 11% (5 of 46), including 1 unconfirmed partial response, with a disease control rate of 50% (23 of 46). All patients who responded to treated (hereafter referred to as responders) had mismatch repair protein-proficient tumors. The median duration of investigator-assessed response was not reached, with a median follow-up of 12.4 months. Among the intention-to-treat population, median progression-free survival was 3.68 months (95% CI, 2.30-5.69 months) and median overall survival was 14.24 months (95% CI, 5.98 months to not reached). Programmed cell death 1 ligand 1 expression in tumors was associated with prolonged progression-free survival (hazard ratio, 0.23; 95% CI, 0.10-0.51; P < .001). The most common treatment-related grade 3 or 4 toxic effects were hyponatremia (3 of 54 [6%]) and increased alkaline phosphatase (2 of 54 [4%]).Conclusions and relevanceThis study found that nivolumab was well tolerated and showed modest efficacy with durable response in patients with refractory BTC. Further studies are warranted to verify the findings and evaluate biomarkers for improved treatment selection for patients.Trial registrationClinicalTrials.gov Identifier: NCT02829918.

Project description:BackgroundAfter the publication of the ABC-02 trial, gemcitabine and cisplatin combination therapy (GP) became the standard first-line treatment for advanced biliary tract cancer (BTC). Despite GP therapy, most patients suffer from disease progression. The ABC-06 trial recommended FOLFOX as a second-line treatment, but its efficacy was modest. In this phase II study, we looked at the efficacy and safety of a second-line modified dose of FOLFIRINOX (mFOLFIRINOX) for patients who had failed first-line gemcitabine-based treatment.MethodsFrom January 2020 to January 2021, 34 patients with advanced BTC who failed first-line gemcitabine-based chemotherapy were enrolled. We evaluated the clinical efficacy and safety outcomes of mFOLFIRINOX.ResultsWith a median follow-up duration of 13.4 months, the median progression-free survival and overall survival was 2.8 months (95% confidence interval (CI): 1.6-4.0 months) and 6.2 months (95% CI: 5.0-7.4 months), respectively. The objective response rate was 14.7% with no complete response. The disease control rate was 61.7%, with a disease control duration of 4.2 months. Due to the rapid progression of the disease, approximately half of all patients received less than three cycles of treatment. The most common type of adverse event (AEs) was hematopoietic AEs. The incidence of non-hematopoietic AEs was relatively low.ConclusionsThe efficacy of mFOLFIRINOX as a second-line treatment in advanced BTC patients after the failure of gemcitabine-based first-line treatment was replicated, albeit with slightly shorter survival results compared to previous studies. Long-term administration of mFOLFIRINOX with toxicity management might offer a survival benefit.

Project description:Patients with advanced biliary tract cancers have limited therapeutic options. Preclinical data suggest that proteasome inhibition may be an effective therapeutic strategy. We thus evaluated the clinical efficacy of bortezomib in advanced biliary tract cancers.Patients with locally advanced or metastatic cholangiocarcinoma or gallbladder adenocarcinoma who had received 0 to 2 previous therapies received bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11 of a 21-day cycle. The primary end point was objective response rate. A Simon 2-stage design was used (null response rate of < 5% and response rate of ? 20% of interest).Twenty patients enrolled (bile duct/gallbladder cancer [14/6] and previous treatments 0/1/2 [10/6/3]). The trial was discontinued early because of lack of confirmed partial responses. No unanticipated adverse events were noted. There was 1 unconfirmed partial response. Ten patients achieved stable disease as best response. Median time to progression was 5.8 months (95% confidence interval [CI], 0.7-77.6 months). Median survival was 9 months (95% CI, 4.6-18.5 months). The 6-month and 1-year survival rates were 70% and 38%, respectively. There was no difference in survival based on primary disease site.Single-agent bortezomib does not result in objective responses in biliary tract cancers. However, the rate of stable disease and time to progression benchmark is encouraging. Further development of bortezomib in combination with other therapies in this disease setting should be considered.

Project description:BackgroundWe sought to determine the safety and efficacy of trifluridine/tipiracil in combination with irinotecan in a phase II trial setting for refractory, advanced unresectable biliary tract carcinoma (BTC).MethodsA total of 28 patients (27 were evaluable) with advanced BTCs who progressed on at least one prior systemic therapy were enrolled and were treated with trifluridine/tipiracil 25 mg/m2 (days 1-5 of 14-day cycle) and irinotecan 180 mg/m2 (day 1 of the 14-day cycle). The primary endpoint for the study was 16-week progression-free survival (PFS16) rate. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and safety were pre-specified secondary endpoints.ResultsOf 27 patients, PFS16 rate was 37% (10/27; 95% CI: 19%-58%), thereby meeting the criteria for success for the primary endpoint. The median PFS and OS of the entire cohort were 3.9 months (95% CI: 2.5-7.4) and 9.1 months (95% CI: 8.0-14.3), respectively. In the patients evaluable for tumor response (n = 20), the ORR and DCR were 10% and 50%, respectively. Twenty patients (74.1%) had at least one grade 3 or worse adverse event (AE), and 4 patients (14.8%) had grade 4 AEs. A total of 37% (n = 10/27) and 51.9% (n = 14/27) experienced dose reductions in trifluridine/tipiracil and irinotecan, respectively. Delay in therapy was noted in 56% of the patients while 1 patient discontinued the therapy, primarily due to hematologic AEs.ConclusionThe combination of trifluridine/tipiracil plus irinotecan is a potential treatment option for patients with advanced, refractory BTCs with good functional status and no targetable mutations. A larger randomized trial is needed to confirm these results. (ClinicalTrials.gov Identifier: NCT04072445).

Project description:ObjectivesTo assess the safety and efficacy of anlotinib (a multi-targeted tyrosine kinase inhibitor) combined with toripalimab (a PD-1 monoclonal antibody) in the treatment of unresectable biliary tract cancer (BTC).MethodsIn this prospective, single-arm, single-centre exploratory clinical study, patients with locally progressed or metastatic BTC were included. Patients were treated with anlotinib (12 mg, PO, QD, for 2 weeks and then stopped for a week, 21 days for a cycle) and toripalimab (240 mg, IV, Q3W). The primary endpoint of the study was the objective response rate (ORR), as defined in RECIST version 1.1 criteria.ResultsIn this study, 15 BTC patients who met the criteria were enrolled. The ORR was 26.7%, the median progression-free survival (mPFS) was 8.6 months (95% CI: 2.1-15.2), the median overall survival (mOS) was 14.53 months (95% CI: 0.8-28.2) and the disease control rate (DCR) was 87.6%. A patient with hilar cholangiocarcinoma was successfully converted after three cycles of treatment and underwent surgical resection. Furthermore, patient gene sequencing revealed that STK11 was mutated more frequently in patients with poor outcomes. In addition, patients with a CD8/Foxp3 ratio > 3 had a longer survival than those with a CD8/Foxp3 ratio ≤ 3 (P = 0.0397).ConclusionsIn patients with advanced BTC, the combination of anlotinib and toripalimab demonstrated remarkable anti-tumor potential, with increased objective response rates (ORR), longer overall survival (OS) and progression-free survival (PFS). Moreover, STK11 and CD8/Foxp3 may be as biomarkers that can predict the effectiveness of targeted therapy in combination with immunotherapy.

Project description:BackgroundThe majority of advanced biliary tract cancer (ABTC) patients will progress after gemcitabine and cisplatin (GP) doublet therapy, while the standard second-line regimen has not been established. We conducted this study to assess the efficacy and safety of second-line irinotecan and capecitabine (XELIRI) regimen vs. irinotecan monotherapy in ABTC patients progressed on GP.MethodsSixty-four GP refractory ABTC patients were randomised to either irinotecan 180 mg/m2 on day 1 plus capecitabine 1000 mg/m2 twice daily on days 1-10 of a 14-day cycle (XELIRI-arm) or single-agent irinotecan 180 mg/m2 on day 1 of a 14-day cycle (IRI-arm). Treatments were repeated until disease progression or unacceptable toxicity occurred.ResultsA total of 60 patients were included in the analysis. For XELIRI and IRI-arms, respectively, the median PFS was 3.7 vs. 2.4 months, 9-month survival rate 60.9% vs. 32.0%, median OS 10.1 vs. 7.3 months, and disease control rate 63.3% vs. 50.0%. The most common grade 3 or 4 toxicities were leucopaenia and neutropaenia.ConclusionsThis randomised, phase II study of irinotecan-containing regimens in good PS second-line ABTC patients showed a clear benefit of XELIRI regimen over irinotecan monotherapy in prolonging PFS, with acceptable toxicity.
