Apatinib in patients with extensive-stage small-cell lung cancer after second-line or third-line chemotherapy: a phase II, single-arm, multicentre, prospective study.

ABSTRACT:

Background

Small-cell lung cancer (SCLC) remains an aggressive cancer with short-term survival due to limited therapeutic options. Apatinib is a small-molecule tyrosine kinase inhibitor that selectively inhibits vascular endothelial growth factor receptor-2. This study aimed to investigate the efficacy and safety of apatinib in patients with extensive-stage (EC) SCLC who had progressed after two or three previous therapies.

Methods

Eligible patients were histologically confirmed ES-SCLC after two or three previous treatments, including a platinum-based regimen. Patients received apatinib at an initial dose of 500 mg once daily. The primary endpoint was the objective response rate.

Results

Forty patients were enrolled. At the data cut-off time (November 15, 2018), the median follow-up was 7.4 months; no patients remained on treatment, and five were still in follow-up. An objective response was achieved in 7 of 40 patients (17.5%) in the intention-to-treat population, and 7 of 38 patients (18.4%) in the per-protocol population. The median progression-free survival and overall survival were 3.0 months and 5·8 months, respectively. The most commonly observed grade 3 or greater treatment-related adverse events were hypertension, hand-foot syndrome, increased L-gamma-glutamyltransferase.

Conclusions

Apatinib exhibited efficacy and an acceptable safety profile in previously heavily-treated ES-SCLC patients. Further exploration of apatinib in phase III trials is warranted.

Project description:BackgroundA paucity of strategies exist for extensive-stage small cell lung cancer (ES-SCLC) patients who fail the first-line chemotherapy. Apatinib is a tyrosine kinase inhibitor (TKI) that selectively inhibits vascular endothelial growth factor receptor-2 (VEGFR-2), which has been demonstrated to have active anti-tumor activity in ES-SCLC when used only or combined with PD-1 inhibitors or chemotherapy with good tolerance. However, the efficacy and safety of apatinib monotherapy is unclear in second-line or beyond treatment of ES-SCLC.MethodsIn this prospective, exploratory, single-arm, multi-center study, eligible patients were aged 18 years or older with histologically confirmed ES-SCLC, and had progressed on, or were intolerant to previous systemic treatment. Patients received apatinib 500 mg (orally qd, every 4 weeks a cycle). The efficacy was assessed after 1 cycle and then every 2 cycles based on computed tomography imaging per the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). The primary endpoint was progression-free survival (PFS). The adverse events (AEs) were assessed per the National Cancer Institute Common Terminology Criteria for Adverse Events 4.0 (NCI-CTCAE 4.0). This study is registered in the Chinese Clinical Trial Registry, number ChiCTR-OPC-17013964.ResultsFrom 28 July 2017 to 21 June 2019, 62 patients were screened for eligibility, among whom 57 patients were available for efficacy and safety analysis. The objective response rate (ORR) was 14.3% and disease control rate (DCR) was 79.6%. The median PFS was 5.6 months [95% confidence interval (CI): 3.3-8.0 months] and the median overall survival (OS) was 11.2 months (95% CI: 7.5-24.0 months). Among the participants who received apatinib as second-line treatment, the median PFS and OS were 6.1 months (95% CI: 2.6-7.6 months) and 12.0 months (95% CI: 7.9 months to not reached), respectively. The most common AEs of all grades were anemia (36.8%), hypertension (33.3%), fatigue (31.6%), blood bilirubin increased (22.8%), elevated transaminase (19.3%), and hand-foot syndrome (17.54%). Grade 3 AEs included 2 (3.5%) cases of hypertension and 1 (1.8%) case of fatigue. No grade 4/5 AEs were observed.ConclusionsApatinib showed encouraging anti-tumor activity in pretreated ES-SCLC patients with tolerable toxicities. Further larger scale studies are warranted to demonstrate the efficacy of apatinib.

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.

Project description:BackgroundPatients with extensive-stage small-cell lung cancer (ES-SCLC) have a particularly poor prognosis. And the treatment options for patients with relapsed or refractory ES-SCLC are limited. Thus, we conducted an open-label, multicenter, single-arm phase II clinical trial to assess the efficacy and safety of apatinib plus etoposide capsules as the third- or further-line treatment in ES-SCLC patients.MethodsPatients with ES-SCLC who experienced disease progression following 2 to 3 previous therapies from 11 medical centers in China were enrolled to receive apatinib (250 mg/d, continuously) and etoposide capsules (50 mg/d, on day 1-21, per 28 days). The treatment continued until disease progression, treatment intolerance, or death. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were objective response rate (ORR), overall survival (OS), and safety.ResultsFifty-six patients with relapsed or refractory ES-SCLC were enrolled from January 2018 to February 2020 and 53 of them were eventually included in the evaluation population. The median follow-up was 9.8 months. At the data cut-off time (March 5, 2020), 39 patients (74%) had died and 44 (83%) had progressed. The median PFS was 3.0 months (95% CI, 2.1-3.9) and the median OS was 5.0 months (95% CI, 3.6-6.4). No complete responses were seen. Eleven patients (21%) showed a best response of partial response and 37 (70%) patients achieved stable disease. The ORR was 20.8% (11/53), and the disease control rate (DCR) was 90.6% (48/53). The 6-month OS rate was 40.1% (95% CI, 26.2-54). After 12 months, the OS rate was 18.4% (95% CI, 4.7-32.1). Possible treatment-related grade III/IV adverse events included leukopenia [8 (15.1%)], neutropenia [7 (13.2%)], anemia [4 (7.4%)], and hand-foot syndrome [2 (3.8%)]. During the study, no mortality occurred as a consequence of treatment.ConclusionsApatinib combined with etoposide capsules exhibits efficacy and has an acceptable safety profile. It could be used as a later-line treatment for ES-SCLC patients who have been heavily pretreated with standard therapies. Further exploration of apatinib combined with etoposide capsules in phase III trials is warranted.
