Therapeutic advances in gastroenterology 20151101 6
Ramucirumab, a fully humanized monoclonal antibody directed against vascular endothelial growth factor receptor 2, is the first targeted agent to have demonstrated an improvement in survival, as a single agent or in combination, in a molecularly unselected population in gastro-oesophageal cancer. Now that second-line treatment is routinely considered for patients with advanced gastro-oesophageal cancer, ramucirumab, with its favourable toxicity profile compared with cytotoxic treatment, provides ...[more]

Project description:BACKGROUND:TP300, a recently developed synthetic camptothecin analogue, is a highly selective topoisomerase I inhibitor. A phase I study showed good safety and tolerability. As camptothecins have proven active in oesophago-gastric adenocarcinomas, in this phase II study we assessed the efficacy and safety of TP300 in patients with gastric or gastro-oesophageal junction (GOJ) adenocarcinomas. METHODS:Eligible patients had metastatic or locally advanced gastric or Siewert Types II or III GOJ inoperable adenocarcinoma. Patients were chemotherapy naïve unless this had been administered in the perioperative setting. TP300 was administered as a 1-h intravenous infusion every 3 weeks (a cycle) for up to 6 cycles at a starting dose of 8 mg/m2 with intra-patient escalation to 10 mg/m2 from cycle 2 in the absence of dose-limiting toxicity. Tumour responses (RECIST 1.1) were assessed every 6 weeks. Toxicity was recorded by NCI-CTCAE version 3.0. Using a modified two-stage Simon design (Stage I and II), a total of 43 patients were to be included providing there were 3 of 18 patients with objective response in Stage I of the study. RESULTS:In Stage I of the study 20 patients (14 males, 6 females), median age 67 years (range 40?-?82), performance status ECOG 0/1, with GC [14] or GOJ carcinoma [6] were enrolled. Of the 16 evaluable patients, 11 received the planned dose increase to 10 mg/m2 at cycle 2, 2 decreased to 6 mg/m2, and 3 continued on 8 mg/m2. There were no objective responses after 2 cycles of treatment. Twelve patients had stable disease for 1?-?5 months and 4 had progressive disease. Median progression free survival (PFS) was 4.1 months (CI [1.6?-?4.9]), median time to progression (TTP) was 2.9 months (CI [1.4?-?4.2]). Grade 3/4 toxicities (worst grade all cycles) included 7 patients (35 %) with neutropenia, 4 patients (20 %) with anaemia, 2 patients (10 %) with thrombocytopenia, and 3 patients (15 %) with fatigue. This study was terminated at the end of Stage I due to a lack of the required (3/18) responders. CONCLUSIONS:This study of TP300 showed good drug tolerability but it failed to demonstrate sufficient efficacy as measured by radiological response.

Project description:AIM:That clinical trial (RAINBOW) showed that a 7.4 months overall survival benefit with the combination therapy with ramucirumab (RAM) and paclitaxel (PAC) as second-line therapy for patients with recurrent or metastatic gastric or gastro-oesophageal junction adenocarcinoma, compared with placebo (PLA) plus paclitaxel. We performed an analysis to assess the cost-effectiveness of RAM from a Chinese perspective and recognized the range of drug costs. METHODS:By building a Markov model to estimate quality-adjusted life-years (QALYs), life-years (LYs) and lifetime costs. Transition probabilities, costs and utilities were estimated for the published literature, Chinese health care system and local price setting. We performed threshold analyses and probabilistic sensitivity analyses to evaluate the uncertainty of the model. RESULTS:Compared with PLA strategy, RAM strategy provided an incremental survival benefit of 1.22 LYs and 0.64 QALYs. The probabilistic sensitivity analysis showed that when RAM costs less than $151 or $753 per 4 weeks, the incremental cost-effectiveness ratio (ICER) approximated the willingness-to-pay threshold (WTP), suggesting that there was 50% likelihood that the ICER for RAM + PAC would be less than $44528.4 per QALY or $48121 per QALY, respectively. CONCLUSIONS:For patients with advanced gastric or gastro-oesophageal junction adenocarcinoma who fail first-line chemotherapy, our results are conducive to the multilateral drug price guidance negotiations of RAM in China.

Project description:Background The current management of advanced gastric or gastro-oesophageal junction adenocarcinoma remains unsatisfactory. We investigated the efficacy and safety of the combination therapy of apatinib and S-1, considering the potential advantage of home-based treatment without hospital admission, in patients with platinum-refractory gastric or gastro-oesophageal junction adenocarcinoma. Methods In this open-label, single-arm, phase 2 trial, in each 21-day cycle, eligible patients received apatinib at an initial dose of 500 mg once daily continuously and S-1 at a dose of 40–60 mg twice daily on days 1–14 until the trail was discontinued disease progression, development of intolerable toxicity, or withdrawal of consent. The primary endpoints were progression-free survival. The secondary endpoints were objective response rates, disease control rates, and safety, and overall survival. This study was registered at ClinicalTrials.gov, NCT04338438. Results Between April 2015 and May 2019, we included 37 patients with advanced gastric or gastro-oesophageal junction adenocarcinoma refractory to first-line platinum-containing therapy. At the data cutoff, the 6-month progression-free survival was 31.5%, the median progression-free survival and overall survival were 4.2 (95% CI: 3.50–4.90) months and 8.2 (95% CI: 4.69–11.71) months, respectively. Of 37 eligible patients, 8 (21.6%) patients reached objective responses, 31 (83.8%) patients reached disease control. Grade 3 or 4 adverse events occurred in 8 (21.6%) patients, including hand-foot syndrome, hypertension, and diarrhea, etc. Conclusions The combination of Apatinib and S-1 showed promising efficacy and manageable toxicity as a home-based, second-line therapy in patients with advanced gastric or gastro-oesophageal junction adenocarcinoma, especially for the elder patients with poor performance status. Trial Registration NCT04338438.

Project description:The human epidermal receptor-2 (HER-2) is amplified in up to 25% of patients with gastroesophageal adenocarcinomas. Although the presence of this amplification does not appear to confer a poor prognosis, it provides a valuable novel therapeutic target for this group of patients. Trastuzumab is a fully humanized monoclonal antibody directed at HER-2 which binds the external domain of the receptor and exerts its action via a combination of antibody-dependent cytotoxicity, reduced shedding of the extracellular domain, inhibition of dimerization and possibly receptor downregulation. The ToGA trial was an international multicentre randomized phase III study which evaluated the addition of trastuzumab to a cisplatin plus fluoropyrimidine chemotherapy doublet in 594 patients with HER-2-positive advanced gastric or oesophagogastric junction adenocarcinoma. The combination of the antibody with chemotherapy significantly improved response rate, median progression-free survival and median overall survival without additional toxicity or adversely affecting quality of life. Accordingly, trastuzumab plus chemotherapy is now a standard first-line treatment option for patients with advanced HER-2-positive gastroesophageal cancer. Unfortunately, many patients with HER-2-positive cancer exhibit primary resistance to trastuzumab and the remainder will acquire resistance to the antibody; therefore, urgent investigation into novel agents which may circumvent resistance mechanisms is warranted. Small molecule inhibitors of HER-2, which commonly also target other members of the HER family of receptors, such as EGFR and HER-3, are currently undergoing evaluation in gastroesophageal cancer as first-line alternatives to trastuzumab and second-line salvage treatments for trastuzumab-resistant disease. Extrapolating the successful use of trastuzumab in the advanced disease setting, clinical trials are underway to assess the role of this antibody in the perioperative and adjuvant settings, where it is hoped that it will have a meaningful impact upon the currently poor survival rates.

Project description:BackgroundFirst-line chemotherapy for advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastro-oesophageal junction adenocarcinoma has a median overall survival (OS) of less than 1 year. We aimed to evaluate first-line programmed cell death (PD)-1 inhibitor-based therapies in gastric, gastro-oesophageal junction, and oesophageal adenocarcinoma. We report the first results for nivolumab plus chemotherapy versus chemotherapy alone.MethodsIn this multicentre, randomised, open-label, phase 3 trial (CheckMate 649), we enrolled adults (≥18 years) with previously untreated, unresectable, non-HER2-positive gastric, gastro-oesophageal junction, or oesophageal adenocarcinoma, regardless of PD-ligand 1 (PD-L1) expression from 175 hospitals and cancer centres in 29 countries. Patients were randomly assigned (1:1:1 while all three groups were open) via interactive web response technology (block sizes of six) to nivolumab (360 mg every 3 weeks or 240 mg every 2 weeks) plus chemotherapy (capecitabine and oxaliplatin every 3 weeks or leucovorin, fluorouracil, and oxaliplatin every 2 weeks), nivolumab plus ipilimumab, or chemotherapy alone. Primary endpoints for nivolumab plus chemotherapy versus chemotherapy alone were OS or progression-free survival (PFS) by blinded independent central review, in patients whose tumours had a PD-L1 combined positive score (CPS) of five or more. Safety was assessed in all patients who received at least one dose of the assigned treatment. This study is registered with ClinicalTrials.gov, NCT02872116.FindingsFrom March 27, 2017, to April 24, 2019, of 2687 patients assessed for eligibility, we concurrently randomly assigned 1581 patients to treatment (nivolumab plus chemotherapy [n=789, 50%] or chemotherapy alone [n=792, 50%]). The median follow-up for OS was 13·1 months (IQR 6·7-19·1) for nivolumab plus chemotherapy and 11·1 months (5·8-16·1) for chemotherapy alone. Nivolumab plus chemotherapy resulted in significant improvements in OS (hazard ratio [HR] 0·71 [98·4% CI 0·59-0·86]; p<0·0001) and PFS (HR 0·68 [98 % CI 0·56-0·81]; p<0·0001) versus chemotherapy alone in patients with a PD-L1 CPS of five or more (minimum follow-up 12·1 months). Additional results showed significant improvement in OS, along with PFS benefit, in patients with a PD-L1 CPS of one or more and all randomly assigned patients. Among all treated patients, 462 (59%) of 782 patients in the nivolumab plus chemotherapy group and 341 (44%) of 767 patients in the chemotherapy alone group had grade 3-4 treatment-related adverse events. The most common any-grade treatment-related adverse events (≥25%) were nausea, diarrhoea, and peripheral neuropathy across both groups. 16 (2%) deaths in the nivolumab plus chemotherapy group and four (1%) deaths in the chemotherapy alone group were considered to be treatment-related. No new safety signals were identified.InterpretationNivolumab is the first PD-1 inhibitor to show superior OS, along with PFS benefit and an acceptable safety profile, in combination with chemotherapy versus chemotherapy alone in previously untreated patients with advanced gastric, gastro-oesophageal junction, or oesophageal adenocarcinoma. Nivolumab plus chemotherapy represents a new standard first-line treatment for these patients.FundingBristol Myers Squibb, in collaboration with Ono Pharmaceutical.

Project description:Gastric carcinoma and gastro-oesophageal junction (GC/GEJ) carcinoma remain a significant global problem, with patients presenting with symptoms often found to have advanced or metastatic disease. Treatment options for these patients have broadened in recent years with new chemotherapy agents, agents targeting angiogenic pathways and the development of immune checkpoint inhibitors (ICIs). Most initial advances have occurred in the refractory setting, where it is important to balance treatment benefits versus toxicity and patient quality of life. In the first-line treatment of advanced/metastatic GC/GEJ, platinum- and fluoropyrimidine-based chemotherapy protocols remain the backbone of therapy (with or without HER2-targeted therapy), with the FOLFIRI regimen offering an alternative in patients deemed unsuitable for a platinum agent. Microsatellite instability-high or mismatch repair-deficient cancers have been shown to benefit most from ICIs. In unselected patients previously treated with doublet or triplet platinum- and fluoropyrimidine-based chemotherapy and second-line chemotherapy with irinotecan or taxanes have formed the backbone of therapy with or without the addition of the vascular endothelial growth factor receptor-2 inhibitor ramucirumab in addition to paclitaxel. Beyond this, efficacy has been demonstrated with oral trifluridine/tipiracil and with single-agent nivolumab, in selected refractory patients. In this review, we highlight the positive evidence from key trials that have led to our current practice algorithm, with particular focus on the refractory advanced disease setting, discussing the areas of active research and highlighting the factors, including biomarkers and the influence of ethnicity, that contribute to therapeutic decision-making.

Project description:ObjectiveThe perioperative chemotherapy with fluorouracil, leucovorin, oxaliplatin plus docetaxel (FLOT) was recommended by the Chinese Society of Clinical Oncology Guidelines for gastric cancer (2018 edition) for patients with resectable gastric or gastro-oesophageal junction adenocarcinoma (class IIA). However, the economic impact of FLOT chemotherapy in China remains unclear. The analysis aimed to compare the cost-effectiveness of FLOT versus epirubicin, cisplatin plus fluorouracil or capecitabine (ECF/ECX) in patients with locally advanced resectable tumours.DesignWe developed a Markov model to compare the healthcare and economic outcomes of FLOT and ECF/ECX in patients with resectable gastric or gastro-oesophageal junction adenocarcinoma. Costs were estimated from the perspective of Chinese healthcare system. Clinical and utility inputs were derived from the FLOT4 phase II/III clinical trial and published literature. Sensitivity analyses were employed to assess the robustness of our result. The annual discount rate for costs and health outcomes was set at 5%.Outcome measuresThe primary outcome of incremental cost-effectiveness ratios (ICERs) was calculated as the cost per quality-adjusted life years (QALYs).ResultsThe base-case analysis found that compared with ECF/ECX, the use of FLOT chemotherapy was associated with an additional 1.08 QALYs, resulting in an ICER of US$851/QALY. One-way sensitivity analysis results suggested that the HR of overall survival and progression-free survival had the greatest impact on the ICER. Probabilistic sensitivity analysis demonstrated that FLOT was more likely to be cost-effective compared with ECF/ECX at a willingness-to-pay threshold of US$31 513/QALY.ConclusionsFor patients with locally advanced resectable tumours, the FLOT chemotherapy is a cost-effective treatment option compared with ECF/ECX in China.Trial registration numberNCT01216644.

Project description:BACKGROUND: The conventional treatment options for advanced gastric patients remain unsatisfactory in terms of response rate, response duration, toxicity, and overall survival benefit. The purpose of this phase II study was to evaluate the activity and safety of cetuximab combined with cisplatin and docetaxel as a first-line treatment for advanced gastric or gastro-oesophageal junction adenocarcinoma. METHODS: Untreated patients with histologically confirmed advanced gastric or gastro-oesophageal adenocarcinoma received cetuximab at an initial dose of 400 mg m(-2) i.v. followed by weekly doses of 250 mg m(-2), cisplatin 75 mg m(-2) i.v. on day 1, docetaxel 75 mg m(-2) i.v. on day 1, every 3 weeks, for a maximum of 6 cycles, and then cetuximab maintenance treatment was allowed in patients with a complete response, partial response, or stable disease. RESULTS: Seventy-two patients (stomach 81.9% and gastro-oesophageal junction 18.1%; locally advanced disease 4.2%; and metastatic disease 95.8%) were enrolled. The ORR was 41.2% (95% CI, 29.5-52.9). Median time to progression was 5 months (95% CI, 3.7-5.4). Median survival time was 9 months (95% CI, 7-11). The most frequent grades 3-4 toxicity was neutropenia (44.4%). No toxic death was observed. CONCLUSIONS: The addition of cetuximab to the cisplatin/docetaxel regimen improved the ORR of the cisplatin/docetaxel doublet in the first-line treatment of advanced gastric and gastro-oesophageal junction adenocarcinoma, but this combination did not improve the TTP and OS. The toxicity of cisplatin/docetaxel chemotherapy was not affected by the addition of cetuximab.

Project description:BackgroundAddition of trastuzumab to first-line chemotherapy improves overall survival in patients with HER2-positive metastatic gastric cancer. We assessed the safety and activity of pembrolizumab in combination with trastuzumab and chemotherapy in first-line HER2-positive metastatic oesophagogastric (gastric, oesophageal, or gastroesophageal junction) cancer.MethodsThis study was an investigator-initiated, open-label, non-randomised, single-arm, single centre, phase 2 trial in patients aged 18 years or older with HER2-positive metastatic oesophagogastric cancer. Eligible patients had measurable or evaluable non-measurable disease, Eastern Cooperative Oncology Group performance status of 0, 1, or 2, and left ventricular ejection fraction of at least 53%. Patients were eligible to receive an initial induction cycle of 200 mg flat dose of intravenous pembrolizumab and 8 mg/kg loading dose of intravenous trastuzumab. For subsequent cycles, patients received 130 mg/m2 of intravenous oxaliplatin or 80 mg/m2 of cisplatin on day 1, 850 mg/m2 of oral capecitabine twice a day for 2 weeks followed by 1 week off (or intravenous 5-fluorouracil, 800 mg/m2 per day on days 1-5), and a 200 mg flat dose of intravenous pembrolizumab, and 6 mg/kg of trastuzumab, administered on day 1 of each 3-week cycle. The primary endpoint was 6-month progression-free survival, defined as the proportion of patients alive and free of progression at 6 months, assessed in patients who received at least one dose of trastuzumab and pembrolizumab. The regimen would be considered worthy of further investigation if 26 or more of 37 patients were progression-free at 6 months. This trial is registered with ClinicalTrials.gov, NCT02954536, and is ongoing, but closed to enrolment.FindingsBetween Nov 11, 2016, and Jan 23, 2019, 37 patients were enrolled. At the time of data cutoff on Aug 6, 2019, median follow-up among survivors was 13·0 months (IQR 11·7-23·5). The primary endpoint was achieved; 26 (70%; 95% CI 54-83) of 37 patients were progression-free at 6 months. The most common treatment-related adverse event of any grade was neuropathy, which was reported in 36 (97%) of 37 patients. The most common grade 3 or 4 adverse events were lymphocytopenia (seven [19%] patients with grade 3 and two [5%] with grade 4), grade 3 decreased electrolytes (six [16%] patients), and grade 3 anaemia (four [11%] patients). Serious adverse events occurred in two patients patients (both grade 3 nephritis leading to treatment discontinuation). Four patients discontinued pembrolizumab because of immune-related adverse events. There were no treatment-related deaths.InterpretationPembrolizumab can be safely combined with trastuzumab and chemotherapy and has promising activity in HER2-positive metastatic oesophagogastric cancer. A randomised phase 3 clinical trial assessing the efficacy and safety of pembrolizumab versus placebo in combination with trastuzumab and chemotherapy in first-line HER2-positive metastatic oesophagogastric cancer is underway.FundingMerck & Co.
