Evaluation of second-line apatinib plus irinotecan as a treatment for advanced gastric adenocarcinoma or gastroesophageal conjunction adenocarcinoma: a prospective, multicenter phase II trial.

ABSTRACT:

Objective

Apatinib and irinotecan are used as systematic therapies for advanced gastric adenocarcinoma (GAC) and gastroesophageal junction adenocarcinoma (GEJA), while the evidence for their combination as second-line therapy in these patients is limited. This study aimed to evaluate the efficacy and safety of second-line apatinib plus irinotecan for the treatment of GAC and GEJA.

Methods

In this prospective, multicenter phase II clinical study, 28 patients with advanced GAC or GEJA who received second-line apatinib plus irinotecan were recruited.

Results

In total, 1 (3.6%) patient achieved complete response, 7 (25.0%) patients achieved partial response, 13 (46.4%) patients had stable disease, and 4 (14.3%) patients showed progressive disease, while clinical response was not evaluable or not assessed in 3 (10.7%) patients. The objective response rate and disease control rate were 28.6% and 75.0%, respectively. Meanwhile, the median (95% confidence interval (CI)) progression-free survival (PFS) was 4.5 (3.9-5.1) months, and the median (95% CI) overall survival (OS) was 11.3 (7.4-15.1) months. By multivariate Cox regression analysis, male sex, liver metastasis, and peritoneal metastasis were independently associated with worse PFS or OS, while treatment duration ≥5 months was independently associated with better OS. In terms of the safety profile, 89.3% of patients experienced treatment-emergent adverse events of any grade, among which 82.1% of patients had grade 1-2 adverse events and 64.3% of patients had grade 3-4 adverse events.

Conclusion

Apatinib plus irinotecan as second-line therapy achieves a good treatment response and satisfactory survival with tolerable safety in patients with advanced GAC or GEJA.

Project description:BackgroundPrevious studies of the second-line treatment for advanced gastric cancer or gastroesophageal junction adenocarcinoma (GC/GEJAC) had reported that apatinib combined with chemotherapy improved the treatment outcomes. However, the benefits were sometimes limited due to the tolerance of continuous dose regimen. This randomized controlled study aimed to investigate the efficacy and safety of intermittent or continuous dose apatinib plus docetaxel as a second-line therapy in patients with advanced GC/GEJAC.MethodsAdvanced GC/GEJAC patients who failed first-line chemotherapy were recruited (enrollment time: from September 15, 2017 to July 21, 2019), and randomly assigned to either the intermittent dose group (IG group) or the continuous dose group (CG group) (1:1 ratio) using the block randomization method. In the IG group, patients received apatinib 500 mg/d for 5 consecutive days then held for 2 days plus docetaxel 60 mg/m2 q3w, in a 3-week cycle. In the CG group, patients received apatinib 500 mg daily plus docetaxel 60 mg/m2 q3w, in a 3-week cycle. The progression free survival (PFS) was evaluated every two cycles and follow-ups were performed monthly. The primary endpoint was PFS, and the secondary endpoints were objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety.ResultsIn total, 76 eligible patients were enrolled and randomly assigned (1:1 ratio). The IG group exhibited similar PFS compared to the CG group [median PFS: 3.88 (95% CI: 1.72-6.03) months vs. 3.98 (95% CI: 1.06-6.90) months, P=0.546] and OS [median OS: 9.00 (95% CI: 5.31-12.70) months vs. 9.40 (95% CI: 5.20-13.59) months, P=0.310]. ORR (21.1% vs. 18.4%, P=0.773) and DCR (60.5% vs. 60.5%, P=1.000) were of not statistically different between the IG and CG groups. As for safety, the IG group exhibited less frequent hypoproteinemia (31.6% vs. 55.3%, P=0.037) and lactate dehydrogenase increased (18.4% vs. 44.7%, P=0.014), while no differences in other adverse events were observed between the two groups.ConclusionsIntermittent dose apatinib plus docetaxel was equally effective and more tolerable than continuous dose apatinib plus docetaxel as a second-line therapy in patients with advanced GC/GEJAC.Trial registrationClinicalTrials.gov NCT03334591.

Project description:ImportanceEfficacy of second-line chemotherapy in advanced gastric or gastrooesphageal junction (GEJ) adenocarcinoma remains limited.OjectivesTo determine the efficacy of 1 or 2 immune checkpoint inhibitors combined with FOLFIRI (leucovorin [folinic acid], fluorouracil, and irinotecan) in the treatment of advanced gastric/GEJ adenocarcinoma.Design, setting, and participantsThe PRODIGE 59-FFCD 1707-DURIGAST trial is a randomized, multicenter, noncomparative, phase 2 trial, conducted from August 27, 2020, and June 4, 2021, at 37 centers in France that included patients with advanced gastric/GEJ adenocarcinoma who had disease progression after platinum-based first-line chemotherapy.InterventionPatients were randomized to receive FOLFIRI plus durvalumab (anti-programmed cell death 1 [PD-L1]) (FD arm) or FOLFIRI plus durvalumab and tremelimumab (anti-cytotoxic T-lymphocyte associated protein 4 [CTLA-4]) (FDT arm). The efficacy analyses used a clinical cutoff date of January 9, 2023.Main outcome and measuresThe primary end point was progression-free survival (PFS) at 4 months according to RECIST 1.1 criteria evaluated by investigators.ResultsOverall, between August 27, 2020, and June 4, 2021, 96 patients were randomized (48 in each arm). The median age was 59.7 years, 28 patients (30.4%) were women and 49 (53.3%) had GEJ tumors. Four month PFS was 44.7% (90% CI, 32.3-57.7) and 55.6% (90% CI, 42.3-68.3) in the FD and FDT arms, respectively. The primary end point was not met. Median PFS was 3.8 and 5.4 months, objective response rates were 34.7% and 37.7%, and median overall survival was 13.2 and 9.5 months in the FD and FDT arms, respectively. Disease control beyond 1 year was 14.9% in the FD arm and 24.4% in the FDT arm. Grade 3 to 4 treatment-related adverse events were observed in 22 (47.8%) patients in each arm. A combined positive score (CPS) PD-L1 of 5 or higher was observed in 18 tumors (34.0%) and a tumor proportion score (TPS) PD-L1 of 1% or higher in 13 tumors (24.5%). Median PFS according to CPS PD-L1 was similar (3.6 months for PD-L1 CPS ≥5 vs 5.4 months for PD-L1 CPS <5) by contrast for TPS PD-L1 (6.0 months for PD-L1 TPS ≥1% vs 3.8 months for PD-L1 TPS <1%).Conclusions and relevanceCombination of immune checkpoint inhibitors with FOLFIRI in second-line treatment for advanced gastric/GEJ adenocarcinoma showed an acceptable safety profile but antitumor activity only in a subgroup of patients.Trial registrationClinicalTrials.gov Identifier: NCT03959293.

Project description:BackgroundFor advanced gastric cancer (GC) patients who fail first-line treatment, chemotherapy alone is of limited benefit. Ramucirumab combined with paclitaxel and apatinib combined with docetaxel provided clinical benefit in previous studies, but the feasibility of apatinib combined with other chemotherapy agents remains unknown. The aim of the present study was to evaluate the efficacy and safety of apatinib combined with chemotherapy as a second-line treatment for advanced GC.MethodsPatients aged 18-75 years with histologically or cytologically confirmed advanced or metastatic GC or gastroesophageal junction adenocarcinoma that had progressed with first-line treatment were recruited and received apatinib 250 or 500 mg oral apatinib and chemotherapy regimens, including docetaxel, paclitaxel, tegafur, oxaliplatin, and capecitabine. Each treatment cycle was 28 days (4 weeks). During post-discontinuation follow-up, all patients were followed for survival [every 8 weeks (+0 to 7 days)] until disease progression, death, or study completion. Overall survival (OS) was the primary endpoint. Secondary endpoints were overall response rate (ORR), disease control rate (DCR), and progression-free survival (PFS). Adverse events (AEs) were also noted. Tumor response and progression were assessed according to RECIST 1.1. AEs were graded following the National Cancer Institute common terminology criteria for AEs (NCI-CTCAE 4.0).ResultsBetween August 31, 2016 and February 17, 2020, a total of 32 patients were enrolled in the present study, and 29 were evaluable. At the time of data cut-off, median follow-up was 7.00 months (IQR, 4.60-12.23 months). The ORR and DCR were 18.52% and 92.59%, respectively. The median PFS was 3.06 months, and the median OS was 6.93 months. In the population receipt of apatinib plus docetaxel, the median OS was 6.51 months. AEs were observed in 22 patients. Leukopenia was the most common AE (24.1%), followed by hypertension (24.1%) and neutropenia (17.2%). Patients did not develop any AEs that were grade 4 or higher.ConclusionsThe combination of apatinib and chemotherapy demonstrated clinical activity and acceptable toxicity as a second-line treatment for advanced GC, and may provide new second-line treatment options for advanced GC patients.
