apatinib and Proteinuria

There is currently no standard treatment strategy for patients with advanced metastatic gastric cancer experiencing progression after two or more lines of chemotherapy. We assessed the efficacy and safety of apatinib, a novel vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor, in patients with advanced gastric or gastroesophageal junction adenocarcinoma for whom at least two lines of prior chemotherapy had failed.. This was a randomized, double-blind, placebo-controlled phase III trial. Patients from 32 centers in China with advanced gastric or gastroesophageal junction adenocarcinoma, for whom two or more prior lines of chemotherapy had failed, were enrolled. Patients were randomly assigned to oral apatinib 850 mg or placebo once daily. The primary end points were overall (OS) and progression-free survival (PFS).. Between January 2011 and November 2012, 267 patients were enrolled. Median OS was significantly improved in the apatinib group compared with the placebo group (6.5 months; 95% CI, 4.8 to 7.6 v 4.7 months; 95% CI, 3.6 to 5.4; P = .0149; hazard ratio, 0.709; 95% CI, 0.537 to 0.937; P = .0156). Similarly, apatinib significantly prolonged median PFS compared with placebo (2.6 months; 95% CI, 2.0 to 2.9 v 1.8 months; 95% CI, 1.4 to 1.9; P < .001; hazard ratio, 0.444; 95% CI, 0.331 to 0.595; P < .001). The most common grade 3 to 4 nonhematologic adverse events were hand-foot syndrome, proteinuria, and hypertension.. These data show that apatinib treatment significantly improved OS and PFS with an acceptable safety profile in patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy.

Apatinib is a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2(VEGFR-2). This study was conducted to assess the efficacy and safety of apatinib in patients with non-triple-negative metastatic breast cancer who had received prior chemotherapy for their metastatic disease.. This multicenter, open-label, single arm study enrolled patients with non-triple-negative breast cancer, pretreated with anthracycline, taxanes and capecitabine, and who failed in the metastatic setting at least 1 and at most 4 prior chemotherapy regimens and at least one endocrine drug for hormone receptor-positive patients as well as at least one anti-Her2 drug for Her2-positive patients. The primary end point of this study was progression free survival (PFS). Secondary end points included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and toxicity. Apatinib was administered as 500 mg daily on days 1 through 28 of each 4-week cycle.. 38 patients were enrolled with a median age of 49 years (range, 35 to 62 years) and received apatinib for a median of 4 cycles (range from 0 to 10 cycles). 18 (47.4%) patients experienced dose reduction during treatment. The median relative dose intensity (relative to assigned dose for each cycle) was 82% (range, 45.0% to 100.0%). Median follow-up time was 10.1 months. Median PFS of all 38 patients was 4.0 months (95% confidence interval (CI), 2.8 m - 5.2 m). 36 patients were eligible for efficacy analysis. ORR was 16.7% (6/36). DCR was 66.7% (24/36). Median OS was 10.3 months (95% CI, 9.1 m - 11.6 m). The most common grade 3/4 treatment-related AEs were hypertension (20.5%), hand-foot syndrome (10.3%), and proteinuria (5.1%). Of three possibly drug-related SAEs recorded in the study, 2 (3.4%) deaths occurred within 28 days of last treatment and were both considered to be the result of disease progression. The other one was grade 2 diarrhea needing hospitalization.. Apatinib exhibited objective efficacy in heavily pretreated, metastatic non-triple-negative breast cancer with manageable toxicity, and it might be better to be tested in breast cancer with high angiogenesis dependency.. ClinicalTrials.gov: NCT01653561.

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related deaths worldwide every year, and most HCC patients are diagnosed with advanced disease and can only receive systemic treatment. TKIs are the most important components of the systemic treatment of HCC and have both good efficacy and adverse events (AEs).  METHODS: This analysis included 207 patients with locally advanced unresectable or metastatic HCC who received oral treatment with apatinib. We analyzed the overall survival (OS) and progression-free survival (PFS) of patients with or without corresponding AEs to evaluate which AEs can predict the efficacy of apatinib.. Patients with hand-foot syndrome (HFS; p = 0.005), proteinuria (p = 0.006) and diarrhea (p < 0.001) had significantly better OS than those without corresponding AEs, and the appearance of HFS (p = 0.006) and proteinuria (p = 0.004) was associated with longer PFS.. Among all the AEs induced by apatinib in the treatment of advanced HCC, proteinuria could potentially predict PFS, and diarrhea was a potential predictor of OS.

Apatinib (Jiangsu HengRui Medicine Co. Ltd), a vascular endothelial growth factor receptor 2 (VEGFR-2) tyrosine kinase inhibitor, has been proven to be safe and to significantly prolong survival in advanced chemotherapy-refractory gastric cancer. This study aimed to assess and compare the efficacy and safety of apatinib combined with chemotherapy with that of chemotherapy alone as second- or higher-line treatment in patients with advanced and metastatic gastric or those with metastatic gastroesophageal junction adenocarcinoma (mGC).Patients with chemotherapy-refractory mGC at Jiangsu Cancer Hospital & Research Institute were prospectively enrolled and assigned into 2 groups at a 2:1 ratio. The first group (combination group) comprised patients with combination treatment (apatinib + chemotherapy), while the second group comprised patients treated with chemotherapy alone (chemotherapy group). The dose of apatinib was 500 mg/d, and the chemotherapy regimens were based on fluoropyrimidine, platinum, and paclitaxel or irinotecan. The primary end points were progression-free survival (PFS).Between November 2014 and December 2016, 175 patients were enrolled. PFS was significantly improved in the combination group compared with that in the chemotherapy group (8.5 months [95% confidence interval [CI], 6.45-10.54] vs 7.0 months [95% CI, 5.12-8.88] P = .021; hazard ratio (HR): 0.645 [95% CI: 0.429-0.969] P = .035). The disease control rate (DCR) was also higher in the combination group than that in the chemotherapy group (58.4% vs 41.9%, P = .041). Moreover, the incidence of Grade 3 to 4 hand-foot syndrome, proteinuria, and hypertension was significantly different between the 2 groups. Combined therapy (P = .040) and metastatic sites <2 (P = .008) were the independent prognostic factors for disease progression.Compared with chemotherapy alone, the addition of apatinib to chemotherapy could better improve PFS and DCR with an acceptable safety profile for mGC refractory to 1 or more line of prior chemotherapy.

There is no standard treatment strategy for patients with extensive-stage small cell lung cancer (SCLC) who have failed two or more prior chemotherapeutic regimens. In this study, we retrospectively evaluated the efficacy and safety of apatinib in patients with extensive-stage SCLC after failure of more than second-line chemotherapy.. A study group comprised of 22 patients with extensive-stage SCLC after failure of more than two prior chemotherapeutic regimens was given apatinib orally at an initial dose of 500 mg daily until disease progression or unacceptable toxicity. This study was analyzed according to the National Cancer Institute Common Toxicity Criteria for adverse events (AEs) and Response Evaluation Criteria in Solid Tumors (RECIST) for response assessment.. Between August 30, 2015, and May 26, 2017, 22 patients were enrolled for evaluating the efficacy and safety of apatinib. Among them, 12/22 (54.5%) underwent dose reduction during treatment. Up to July 31, 2018, the median progression-free survival rate was 135.0 days [95% confidence interval (CI) 63.8-206.2]. According to the RECIST criteria, the disease control rate (DCR) was 86.4%, 19/22 [comprised of partial response (PR) 18.2%, 4/22; and stable disease (SD) 68.2%, 15/22 patients]. The most frequent AEs were hand-foot syndrome (45.5%, 10/22), secondary hypertension (45.5%, 10/22) and fatigue (40.9%, 9/22). The primary grade 3 or 4 toxicities were hypertension (22.7%, 5/22), hand-foot syndrome (13.6%, 3/22), and proteinuria (9.1%, 2/22).. Apatinib exhibits modest activity and acceptable toxicity for patients with heavily pretreated extensive-stage SCLC.

Antiangiogenic therapy has shown improved clinical outcome in metastatic colorectal cancer (mCRC). After the failure of standard treatments, regorafenib and TAS-102 would be recommended for patients with mCRC, however, they have not been approved in China during this study period.. This pilot study aimed to assess the efficacy and safety of apatinib, a novel oral inhibitor targeting vascular endothelial growth factor receptor 2, as third-line treatment for patients with mCRC refractory to standard therapies. In this retrospective study, all patients received apatinib treatment until progressive disease (PD), death, unacceptable toxicity, and curative surgery. The dose or treatment schedule was modified according to the physician's discretion according to the toxicity profiles.. Between March 2015 and June 2017, 36 patients were enrolled and eligible for evaluation of the safety and efficacy. One patient (2.8%) achieved complete response, 3 (8.3%) achieved partial response, 24 (66.7%) achieved stable disease, and 8 (22.2%) PD. The objective response rate and the disease control rate were 11.1% (4 of 36), and 77.8% (28 of 36), respectively. Moreover, the median overall survival (OS) since the initiation of first-line treatment was 33.2 months. The median progression-free survival (PFS) and median OS from apatinib treatment were 4.8 and 10.1 months, respectively. Intergroup analysis showed that there was no significant difference in median PFS and median OS between patients who were previously treated with and without bevacizumab. The most common Grade 3 to 4 adverse reactions were hand-foot syndrome, hypertension, and proteinuria.. Our results suggested that apatinib was active as a third-line treatment of refractory mCRC with a manageable tolerability profile. In addition, preliminary data suggested that the efficacy of apatinib would not be affected by previous bevacizumab treatment. Further prospective randomized controlled clinical trials are urgently needed.
