The Effects of Drug Exposure and Single Nucleotide Polymorphisms on Aaptinib-Induced Severe Toxicities in Solid Tumors. Drug Metab Dispos 2023; 51:1583-1590. [PMID: 37775332 DOI: 10.1124/dmd.123.001428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/25/2023] [Accepted: 09/05/2023] [Indexed: 10/01/2023] Open
Abstract
To investigate the value of drug exposure and host germline genetic factors in predicting apatinib (APA)-related toxicities. METHOD In this prospective study, plasma APA concentrations were quantified using liquid chromatography with tandem mass spectrometry, and 57 germline mutations were genotyped in 126 advanced solid tumor patients receiving 250 mg daily APA, a vascular endothelial growth factor receptor II inhibitor. The correlation between drug exposure, genetic factors, and the toxicity profile was analyzed. RESULTS Non-small cell lung cancer (NSCLC) was more prone to APA-related toxicities and plasma concentrations of APA, and its main metabolite M1-1 could be associated with high-grade adverse events (AEs) (P < 0.01; M1-1, P < 0.01) and high-grade antiangiogenetic toxicities (APA, P = 0.034; P < 0.05), including hypertension, proteinuria, and hand-foot syndrome, in the subgroup of NSCLC. Besides, CYP2C9 rs34532201 TT carriers tended to have higher levels of APA (P < 0.001) and M1-1 (P < 0.01), whereas CYP2C9 rs1936968 GG carriers were predisposed to higher levels of M1-1 (P < 0.01). CONCLUSION Plasma APA and M1-1 exposures were able to predict severe AEs in NSCLC patients. Dose optimization and drug exposure monitoring might need consideration in NSCLC patients with CYP2C9 rs34532201 TT and rs1936968 GG. SIGNIFICANCE STATEMENT Apatinib is an anti-VEGFR2 inhibitor for the treatment of multiple cancers. Though substantial in response, apatinib-induced toxicity has been a critical issue that is worth clinical surveillance. Few data on the role of drug exposure and genetic factors in apatinib-induced toxicity are available. Our study demonstrated a distinct drug-exposure relationship in NSCLC but not other tumors and provided invaluable evidence of drug exposure levels and single nucleotide polymorphisms as predictive biomarkers in apatinib-induced severe toxicities.

RESULTS Seven patients were included in the efficacy analysis. The median PFS2 of apatinib combined with EGFR-TKI was 8.2 months (95% CI, 7.3 m-NA), and the total PFS reached 20.9 months (95% CI, 17.3 m-NA) when plus PFS1. All the adverse events were manageable. The median PFS was significantly longer for circulating tumor DNA (ctDNA)-cleared patients (8.4 months; 95% CI, 8.2-NA) than for those ctDNA not cleared (7.1 months; 95% CI, 6.9-NA) (p = 0.0082). DISCUSSION The addition of apatinib did improve the duration of first-generation EGFR-TKI use, and the duration was better than the first-line use of third-generation EGFR-TKI. CONCLUSION The addition of apatinib when the patients got slow progression after initial EGFR-TKI therapy may be a good treatment option and the side effects are controllable. It is possible to monitor treatment efficacy using ctDNA.

Pharmacokinetics, safety, tolerability, and feasibility of apatinib in combination with gefitinib in stage IIIB-IV EGFR-mutated non-squamous NSCLC: a drug-drug interaction study. Cancer Chemother Pharmacol 2023; 92:411-418. [PMID: 37518060 DOI: 10.1007/s00280-023-04563-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 06/26/2023] [Indexed: 08/01/2023]
Abstract
PURPOSE Apatinib combined with gefitinib was proven to benefit advanced EGFR-mutant NSCLC patients in first-line treatment. This study aimed to evaluate the drug-drug interaction of gefitinib and apatinib when coadministered in EGFR-mutated NSCLC patients. METHODS In this phase 1b, multi-center, open-label, fixed-sequence study, the drug-drug interaction of gefitinib and apatinib was evaluated when coadministered in EGFR-mutated NSCLC patients. Patients received single-agent apatinib 500 mg QD on days 1-4. Gefitinib 250 mg QD was given on days 5-15 and combined with apatinib 500 mg QD on days 12-15. Serial blood samples were drawn on days 4 and 15. The plasma concentrations and other pharmacokinetics parameters were measured for apatinib with and without gefitinib. RESULTS The study enrolled 22 patients and 20 were analyzed for pharmacokinetics. There were no distinct differences in apatinib Cmax and AUC0-τ with versus without gefitinib (geometric LSM ratio, 0.96 [90% CI 0.84-1.10] for Cmax and 1.12 [90% CI 0.96-1.30] for AUC0-τ). Similar PFS and grade of treatment-emergent adverse events (TEAEs) were found between different Cmax and AUC0-τ of apatinib and gefitinib at 500 mg apatinib and 250 mg gefitinib dose levels. CONCLUSIONS Apatinib pharmacokinetics parameters were not significantly changed when coadministered with gefitinib. All TEAEs were manageable, and there was no need to change the dose level when combining apatinib and gefitinib (ClinicalTrials.gov identifier: NCT04390984, May 18, 2020).

Abstract
INTRODUCTION Lung cancer is the second most common cancer in the world and the leading cause of cancer-related mortality. Immune checkpoint inhibitors (ICIs), as monotherapy or in combination with platinum-based chemotherapy, have emerged as the standard of care first-line treatment option for patients with advanced non-small cell lung cancer (NSCLC) without actionable genomic alterations (AGAs). Despite significant improvements in patient outcomes with these regimens, primary or acquired resistance is common and most patients develop disease progression, resulting in poor survival. AREAS COVERED We review the current treatments commonly used for NSCLC without AGAs in the first-line and subsequent settings and describe the unmet needs for these patients in the second-line setting, including a lack of standard definitions for primary and required resistance, and few effective treatment options for patients who develop progression of their disease on first-line therapy. We describe key mechanisms of resistance to ICIs and emerging therapies that are being investigated for patients who develop progression on ICIs and platinum-based chemotherapy. EXPERT OPINION Emerging agents in development have a variety of different mechanisms of action and will likely change standard of care for second-line therapy and beyond for patients with NSCLC without AGAs in the future.

Abstract
BACKGROUND Apatinib (YN968D1) is the first small-molecule-targeting drug with anti-tumor activity created in China for the treatment of advanced gastric cancer (GC) and hepatocellular carcinoma (HCC). It showed significant variation in the efficacy for treating cancers, including advanced non-squamous non-small-cell lung cancer (NSCLC). Whether its efficacy could be optimized by subgrouping patients with certain genetic variation remains elusive. METHODS Here, we firstly used kinase screening to identify any possible target of apatinib against 138 kinases. The effects of apatinib on proliferation rates, cell cycle, cell apoptosis, and cell migration on cancer cell lines were analyzed; the in vitro potential pathways of apatinib on cancer cell lines were screened. The effect of apatinib on mouse cancer models in vivo was also analyzed. RESULTS Based on HCC364 cells with BRAF V600E mutation, we have shown that apatinib could inhibit their growth, migration, cell cycle, and induce their apoptosis. Based on mice with transplanted HCC364 cells, we have also shown that apatinib could inhibit the tumor growth. Based on immunohistochemistry, we have demonstrated that apatinib could suppress the phosphorylation of mitogen-activated protein kinase/extracellular signal-regulated kinase and extracellular regulated protein kinases. This may account at least part of the apatinib's inhibitory effect on HCC364 cancer cells. CONCLUSIONS BRAF V600E protein kinase is a target of apatinib by kinase screening. We have demonstrated that apatinib can effectively inhibit tumor cells with BRAF V600E mutation by in vitro and in vivo experiments. Our results have demonstrated that targeting BRAF V600E mutation, apatinib appears to be effective and safe for treating NSCLC and possibly other cancers with the same mutation.

Abstract
Background As a potent inhibitor of the vascular endothelial growth factor (VEGF) signaling pathway, Apatinib has been used in antitumor treatment for some time. The study aimed to research the therapeutic effects and toxicity of Apatinib in the treatment of advanced non-small cell lung cancer (NSCLC). Methods We retrospectively analyzed 128 NSCLC patients treated with Apatinib in Qilu Hospital of Shandong University. Response Evaluation Criteria in Solid Tumors (RECIST) criteria was adopted to evaluate the treatment effect, and Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 was conducted to determine the Adverse Events (AEs). Cox proportional hazard model and Kaplan-Meier function were applied to evaluate the progression-free survival (PFS) and overall survival (OS). Results Among 128 NSCLC patients, partial response (PR) were observed in 15 patients, stable disease (SD) in 66 patients and progressive disease (PD) in 47 patients. The objective response rate (ORR) and disease control rate (DCR) accounted for 11.7% and 63.3% respectively. The median PFS (mPFS) and median OS (mOS) were 4.4 months and 17.2 months. Common side effects of Apatinib were hypertension (n=48), proteinuria (n=35), and hand-foot syndrome (HFS) (n=30), all of the side effects were controllable. No significant difference was observed in efficacy and AEs between the higher dose group (Apatinib>500mg/d) and the lower dose group (Apatinib=500mg/d). Conclusions The study suggested that Apatinib with a lower dose (=500mg/d) has good efficacy and safety in the treatment of advanced NSCLC after first-line chemotherapy.

Abstract
Background and purposeThe objective of this study was to investigate the pharmacokinetics, safety, and antitumor activity of apatinib, a vascular endothelial growth factor receptor 2 inhibitor, in advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma and evaluate the effect of dose titration on dosage optimization for individual patients.MethodsPatient with advanced gastric adenocarcinoma progressed after at least one line of chemotherapy were enrolled. Apatinib was given orally once daily starting at 500 mg for 14 days, then up-titrated to 750 mg for 14 days, and then proceeded to a maximum dose of 850 mg. Dose up-titration determination was based on toxicity. The 28-day treatment cycles continued until disease progression, intolerable toxicities, withdrawal of consent, or investigator’ decision.ResultsA total of 60 patients were enrolled, with 17, 18, and 25 patients receiving a maximum dose of 500 mg, 750 mg, and 850 mg, respectively. The pharmacokinetic parameters varied considerably, with the interpatient coefficient of variation for steady state areas under the plasma concentration time curve (AUCss) and the mean maximum concentration of both > 50%. During 500 mg and 750 mg dosing stage, drug exposures in patients with a maximum dosage of 850 mg were lower than in those not titrated to 850 mg. Patients with total gastrectomy exhibited significantly lower AUCss than patients with partial or no gastrectomy (p = 0.004 and 0.032, respectively). Toxicities were tolerable, and disease control rate was 39.5% (95% CI 25.0%−55.6%).ConclusionsApatinib dose titration based on toxicity could be used in clinical practice to provide optimal dosage for individual patients.Clinical Trial registrationhttps://clinicaltrials.gov/ct2/show/NCT02764268?term=NCT02764268&draw=2&rank=1, NCT02764268.

Abstract
RATIONALE Outcomes remain poor in children with recurrent ependyomams (rEPNs), despite advances in surgery and radiotherapy. Systemic therapeutic options are limited, given the low response to chemotherapy and targeted drugs. There is an urgent need for efective pharmacotherapy. Apatinib is a multitarget tyrosine kinase inhibitor, which has been reported to exhibit broad antitumor profiles. However, its effects on rEPNs have not been reported thus far. PATIENT CONCERNS We present a 5-year-old recurrent ependyomam patient benefting from apatinib and temozolomide. The patient was diagnosed with ependyomam in January 2016 and treated with surgery and radiotherapy. After surgery, the patient walked with an mild unsteady gait. He was diagnosed with recurrence in November 2018 following which he was treated with reoperation, reirradiation and chemotherapy (etopside, cisplatin, and temozolomide [TMZ]). The patients increased gait instability in April 2019. DIAGNOSES Magnetic resonance imaging (MRI) showed progression of the disease. The lession at the left edge of the fourth ventricle and cerebellar peduncles was significantly increased. INTERVENTIONS The patient was administer TMZ (200 mg/m2/d, d1-5, 28 days as a cycle) + apatinib (250 mg, every other day). Twelve cycle of TMZ and apatinib were given. OUTCOMES The tumor significantly shrank during the patient received TMZ and apatinib. After 9 months of medication, MRI revealed a nearly complete response However, the tumor progressed on May 5, 2020. From the beginning of the application of TMZ and apatinib, the progression-free survival was 1 year and the survival time was 19 months. Grade 1 leukocytopenia was observed without other adverse effects. CONCLUSION Apatinib and temozolomide treatment with mild side effects may be a new option for children with recurrent ependyomams.

Abstract
Background Camrelizumab plus apatinib shows encouraging antitumor activity and acceptable toxicity in chemotherapy-pretreated patients with advanced non-small cell lung cancer (NSCLC); however, clinical benefits from this combination regimen in NSCLC patients with EGFR mutations or ALK rearrangements (EGFR+/ALK+) have not been reported. We assessed the efficacy and safety of this combined regimen in pretreated patients with advanced NSCLC and defined EGFR/ALK status (EGFR+/ALK+) in a phase 1b/2 trial. Methods Previously treated patients with advanced EGFR+/ALK+ NSCLC were enrolled and given camrelizumab 200 mg intravenously every 2 weeks plus apatinib at the recommended dose of 250 mg orally once daily. Patients harboring sensitive EGFR mutations or ALK fusion genes had received at least one EGFR/ALK TKI and a platinum-based chemotherapy regimen before the enrollment. The primary endpoint was objective response rate (ORR). Results All 43 enrolled patients comprised the efficacy and safety analysis population. The confirmed ORR was 18.6% (95% CI: 8.4–33.4%) and the clinical benefit response rate was 27.9% (95% CI: 15.3–43.7%). Median progression-free survival (PFS) was 2.8 months (95% CI: 1.9–5.5 months) and median overall survival was not reached (95% CI: 7.3 months–not reached), with a median follow-up period of 15.7 months (range, 0.5–24.4 months). The most common grade ≥3 treatment-related adverse events (TRAEs) were hypertension (16.3%), proteinuria (11.6%) and palmar-plantar erythrodysaesthesia syndrome (9.3%). No unexpected adverse events were recorded. Conclusions Camrelizumab plus apatinib showed moderate antitumor activity and acceptable safety profile in previously treated patients with advanced NSCLC and EGFR or ALK genetic aberrations, which warranted further validation.

Abstract
Background Anlotinib is a multitarget tyrosine kinase inhibitor for treating patients with advanced non-small cell lung cancer (NSCLC). We aimed to assess the efficacy and safety of anlotinib in elder patients with advanced NSCLC. Methods Elder patients with advanced NSCLC who received anlotinib were enrolled. They were all age ≥ 65 years and with demonstrated records of EGFR gene status. All patients had received treatment with anlotinib or immune checkpoint inhibitors (ICIs)/EGFR-TKIs. The efficacy was evaluated according to the efficacy evaluation criteria for solid tumors (RECIST 1.1). Common Adverse Events Evaluation Criteria (CTCAE 4.03) were used to evaluate adverse drug reactions. Results A total of 91 patients were included in this study. We divided the patients into two groups (EGFR wild type: 60 patients; EGFR mutation: 31 patients). Among EGFR negative patients, the progression-free survival (PFS) for anlotinib monotherapy and anlotinib combination ICI therapy was 3.2 months and 5.0 months, respectively (P = 0.012). The difference in overall survival (OS) between monotherapy and combination therapy was also significant (9.5 vs. 18.4 months, respectively P = 0.010). Interestingly, we further analyzed differences between patients with hypertension and without hypertension, and found that hypertension was associated with better prognosis (5.7 vs. 1.4 months, P < 0.0001). In the EGFR mutation group, the PFS for anlotinib and EGFR-TKI combination treatment indicated better efficacy than that of anlotinib monotherapy (1.83 months vs. 7.03 months, respectively, P = 0.001). The median OS for monotherapy and combination therapy in the EGFR mutation group showed no statistical difference (28.34 months vs. 31.37 months, P = 0.223). The most common adverse reactions were hypertension, fatigue, and hand-foot syndrome, mainly of grade 1 or 2. No significant increase in adverse reactions was observed in patients ≥ 70 years of age. Conclusions Anlotinib treatment and combination regimens resulted in good efficacy and controllable adverse reactions in elder patients with advanced NSCLC.

Abstract
Lung cancer remains the leading cause of cancer-related death world-wide. Therapy resistance and relapse are considered major reasons contributing to the poor survival rates of lung cancer. Accumulated evidences have demonstrated that a small subpopulation of stem-like cells existed within lung cancer tissues and cell lines, possessing the abilities of self-renewal, multipotent differentiation and unlimited proliferation. These lung cancer stem-like cells (LCSCs) can generate tumors with high effeciency in vivo, survive cytotoxic therapies, and eventually lead to therapy resistance and recurrence. In this review, we would like to present recent knowledges on LCSCs, including the origins where they come from, the molecular features to identify them, and key mechanisms for them to survive and develop resistance, in order to provide a better view for targeting them in future clinic.

Targeting ADRB2 enhances sensitivity of non-small cell lung cancer to VEGFR2 tyrosine kinase inhibitors. Cell Death Dis 2022; 8:36.

Abstract
Vascular Endothelial Growth Factor Receptor 2 (VEGFR2) tyrosine kinase inhibitors (TKIs) have achieved remarkable clinical progress in the treatment of non-small-cell lung cancer; however, resistance has limited their therapeutic efficacy. Therefore, understanding the mechanisms of VEGF-TKI and ICI resistance will help to develop effective treatment strategies for patients with advanced NSCLC. Our results suggested that treatment with VEGFR2-TKIs upregulated ADRB2 expression in NSCLC cells. Propranolol, a common ADRB2 antagonist, significantly enhanced the therapeutic effect of VEGFR2-TKIs by inhibiting the ADRB2 signaling pathway in NSCLC cells in vitro and in vivo. Mechanically, the treatment-induced ADRB2 upregulation and the enhancement of ADRB2/VEGFR2 interaction caused resistance to VEGFR2-TKIs in NSCLC. And the inhibition of the ADRB2/CREB/PSAT1 signaling pathway sensitized cells to VEGFR2-TKIs. We demonstrated that ADRB2 signaling is crucial in mediating resistance to VEGFR2-TKIs and provided a novel promising combinatory approach to enhance the antitumor effect of VEGFR2-TKIs in NSCLC combining with propranolol.

Abstract
Background The outcomes of advanced non-small cell lung cancer (NSCLC) patients after first- or second-line therapy are still discouraging due to a lack of effective treatment strategies. As a novel oral anti-angiogenesis drug, apatinib, approved by the National Medical Products Administration of China only for advanced gastric cancer, has been increasingly used in off-label treatment across various cancer types in recent years, especially advanced NSCLC. It has shown strong anti-tumor efficacy and acceptable safety. Methods This prospective study (NCT02974933) was conducted in patients with advanced NSCLC, who had suffered disease progression from the first- or second-line treatment, in Hubei Cancer Hospital. Eligible patients were enrolled and administrated with apatinib mesylate (500 mg qd) in combination with pemetrexed (500 mg/m2, every 4 weeks). The primary endpoint was progression-free survival (PFS). Results From September 2016 to September 2019, a total of 21 advanced NSCLC patients were enrolled in Hubei Cancer Hospital. As of January 2021, treatment was discontinued in all patients, with 1 still in follow-up. There were 7/21 (33.3%) patients who achieved objective response. The median PFS and median overall survival (OS) were 7.0 months (95% CI: 6.15-7.85 months) and 13.0 months (95% CI: 7.39-18.6 months), respectively. Toxicities were tolerable or could be clinically managed. The most common grade 3-4 adverse events (AEs) were hypertension (14.3%, 3/21), hand-foot syndrome (4.7%, 1/21), and proteinuria (4.7%, 1/21). Hematological toxicities were moderate, with rare occurrences of grade 3/4 toxicities. During the period of treatment, there was no occurrence of treatment-related death. Conclusions Apatinib plus pemetrexed demonstrated promising efficacy and a high level of safety profile in previously heavily-treated NSCLC patients. More definitive studies on the combination of apatinib and pemetrexed are warranted.

Abstract
Apatinib is a multitarget tyrosine kinase inhibitor marketed in China for the treatment of advanced gastric cancer (GC) and hepatocellular carcinoma (HCC). It has also been used off-label for the treatment of many other malignancies. To comprehensively evaluate the efficacy of apatinib as a targeted therapy in the treatment of malignancies, we conducted systematic online and manual searches of the literature on apatinib in the treatment of malignancies. In this review, we first summarized the efficacy of apatinib against various malignancies based on clinical trials where results have been reported. In prospectively registered trials, apatinib has been proven to be effective against GC, HCC, lung cancer, breast cancer, sarcoma, esophageal cancer, colorectal cancer, ovarian cancer, cervical cancer, cholangiocarcinoma, diffuse large B-cell lymphoma, nasopharyngeal carcinoma, and differentiated thyroid cancer. The response biomarkers for apatinib were also reviewed. This review will serve as a good reference for the application of apatinib in clinical studies and the design of clinical trials.

Abstract
Apatinib mesylate is an oral antiangiogenic agent that can inhibit activation of vascular endothelial growth factor receptor-2 tyrosine kinase. However, its therapeutic use in liver cancer is restricted due to severe systemic toxicity. Our work aimed to construct apatinib-loaded CalliSpheres Beads (CBAPA) and investigate its application in transarterial chemoembolization (TACE) of liver cancer. The established stock solution containing 20, 40 or 60 mg apatinib were fully mixed with 100-300 μm CalliSpheres Beads (CB) for 2 hours, respectively. The highest loading efficiency at 30 min after combination in 20 mg group (maximum 70.7%). Further, apatinib can be steadily released from CBAPA in vitro release test. For pharmacokinetics and tumor response in vivo, sixty New Zealand white rabbits with VX2 liver tumor were assigned into four groups: sham (NS) group, apatinib solution alone (APA) group, CB group and CBAPA group. Apatinib was measured in plasma and liver tissue by high performance liquid chromatography-tandem mass spectrometry. Compared to APA group, the administration of apatinib by TACE with CBAPA resulted in low systemic concentration. In addition, intratumoural apatinib concentration was higher than adjacent hepatic parenchyma in the CBAPA group. Compared to other three groups, CBAPA group achieved lower tumor growth rate and improved survival time. In conclusion, these findings provide a basis for the potential application of apatinib-loaded CalliSpheres Beads in liver cancer.

Abstract
Apatinib is a new oral tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor-2. It has been proven effective in treating multiple solid tumors. Herein, we report the case of a 67-year-old Chinese patient who was diagnosed with recurrent and malignant transformation of intrahepatic biliary cystadenoma. After multidisciplinary team discussion, the team considered that the remaining liver volume was insufficient for surgical resection. The patient refused chemotherapy and radiotherapy and was willing to take apatinib. Initially, the patient experienced severe tongue ulcers and difficulty eating. The dose of apatinib was then adjusted to 250 mg/day. To date, he has been taking apatinib for 48 months. Regular re-examination showed that the tumor had significantly decreased in size. On January 16, 2021, a CT scan revealed a tumor diameter of 4.5 cm. In our case, the patient achieved partial response and progression-free survival(PFS) of 48.0 months. During treatment, the patient’s appetite and mental state were expected. The treatment did not induce hypertension, fatigue, hand-foot syndrome, or liver and kidney damage. Apatinib may be an option for the treatment of advanced intrahepatic biliary cystadenocarcinoma. Its toxicity is controllable and tolerable. The exact curative effect still needs to be evaluated in more cases.

Abstract
BACKGROUND Symptomatic multiple brain metastases with peritumoral brain edema (PTBE) occur in non-small cell lung cancer patients (NSCLC) who are without driver mutations or are resistant to epidermal growth factor tyrosine kinase (EGFR-TKI) are often associated with an unfavorable prognosis. Whole brain radiation therapy (WBRT) which comes with many complications and unsatisfactory effects, is the only option for the treatment. Previous studies have shown that bevacizumab can reduce the volume of PTBE and improve efficiency of radiotherapy. This study evaluated the effects and safety of apatinib combined with WBRT in NSCLC patients with symptomatic multiple brain metastases and PTBE. METHODS We performed a retrospective review of 34 patients with symptomatic multiple brain metastases from NSCLC (number >4, and at least 1 measurable brain metastasis lesion with cerebral edema). Intracranial objective response rate (IORR), peritumoral edema and intracranial tumor volumetric measurement, Karnofsky performance status (KPS) and adverse events (AEs) were evaluated. Median intracranial progression-free survival (mIPFS) and median overall survival (mOS) were also analyzed. RESULTS Thirteen cases received apatinib (125 mg or 250 mg, QD, oral) combined with WBRT and 21 cases received chemotherapy combined with WBRT were inclued. Apatinib combination group can better reduce the volume of intracranial tumors and PTBE and total steroid dosage used. It was associated with a better IORR (84.6% vs 47.6%, P = 0.067), longer mIPFS (6.97 vs 4.77months; P = 0.014). There was no significant difference in mOS(7.70 vs 6.67 months; P = 0.14) between the 2 groups. The most common adverse events of apatinib combination WBRT included grade 1/2 nausea (4/13), fatigue (3/13), hypertension (2/13) and white blood cell decrease (2/13). No grade 3/4 AEs were observed. CONCLUSION Apatinib plus WBRT is well tolerated and may be a potential choice for relapsed or drug-resistant advanced NSCLC patients with symptomatic multiple brain metastases and PTBE.

Abstract
OBJECTIVE The incidence of skin squamous cell carcinoma (SSCC) has recently been increasing, with diverse clinical manifestations.SSCC could metastasize to lymph nodes or other organs, posing a great threat to life. The present study was designed to investigate the function and underlying mechanism of muscleblind-like protein 1 (MBNL1) in skin squamous cell carcinoma. METHODS SCL-1 cell was used for vitro model and transfected with MBNL1 or siMBNL1 plasmids. MTT Assays, LDH activity ELISA, and Transwell chamber migration experiment were used to confirm the effects of MBNL1 on cell growth of SCL-1 cell. Western blot analysis was used to analyze the mechanism of MBNL1 in SCL-1 cell. RESULTS Down-regulation of MBNL1 promoted cell metastasis of SSCC, while up-regulation of MBNL1 reduced cell metastasis of SSCC in vitro. Down-regulation of MBNL1 suppressed the protein expression of T cell intracellular antigen (TIAL1), myogenic determinant 1 (MyoD1) and Caspase-3 in vitro. Consistent with these observations, inhibition of TIAL1 or MYOD1 expression attenuated the effects of MBNL1 in SSCC. CONCLUSION The present study revealed that MBNL1 suppressed thecancer metastatic capacity of SSCC via by TIAL1/MYOD1/Caspase-3 signaling pathways.

Abstract
Background The aim of the present study was to investigate the influence of kinase insert domain containing receptor (KDR) genetic variation on the efficacy of treatment and safety of patients with chemotherapy-refractory metastatic colorectal cancer (CRC) receiving apatinib. Methods A total of 108 patients with chemotherapy refractory metastatic CRC who were treated with apatinib participated in this study retrospectively. Efficacy of the patients' treatment was evaluated. Prognosis was carried out and safety profile was documented, respectively. Blood specimens and peripheral blood mononuclear cells (PBMC) of the patients were obtained for the analysis of genetic variation and KDR gene mRNA expression, respectively. The association between genotype status and clinical outcomes was presented. Results Objective response rate (ORR) and disease control rate (DCR) of the 108 patients with metastatic CRC receiving apatinib treatment were 5.6% and 69.4%, respectively. Survival analysis results exhibited that the median progression-free survival (PFS) and overall survival (OS) of the 108 patients with metastatic CRC was 3.6 months (95% confidence interval (CI): 3.03-4.17 months) and 8.9 months (95% CI: 7.57-10.23 months), respectively. Subsequently, the analysis of KDR genetic variation indicated that rs2071559 was of clinical significance. The minor allele frequency of rs2071559 was 0.22 and the genotype status corresponded with Hardy-Weinberg equilibrium (P=0.949). Prognosis analysis in a dominant inheritance manner through the combination of patients with TC and CC genotype showed that the median PFS of patients with TT genotype and TC/CC genotype was 4.1 and 3.0 months, respectively (P=0.012). Furthermore, the median OS of patients with the two genotypes was 10.5 and 6.1 months, respectively (P=0.007). Additionally, multivariate Cox regression analysis of OS showed that TC/CC genotype was an independent factor for OS (Hazard ratio (HR)=0.65, P=0.021). Interestingly, mRNA expression analysis suggested that the mRNA expression of KDR in PBMC differed significantly according to rs2071559 genotype status (P<0.001). Conclusion Apatinib demonstrated a potentially superior clinical outcome for patients with chemotherapy-refractory metastatic CRC. KDR polymorphism rs2071559 could be used as a potential biomarker for the prognosis evaluation of patients with CRC receiving apatinib therapy.

METHODS A total of 128 patients with chemotherapy-refractory ES-SCLC who were treated with apatinib at an initial dosage of 250 or 500 mg were included in this study. The change of target lesions was assessed. Overall response rate (ORR) was evaluated. Prognosis was carried out and safety profile was documented. Additionally, peripheral blood and biopsy cancer tissue specimens of the patients with SCLC were collected for the analysis of polymorphism and VEGFR2 gene mRNA expression, respectively. The association between genotype status and baseline characteristics was performed. Univariate analysis of genotype status and prognosis was carried out using Kaplan-Meier survival analysis and multivariate analysis were adjusted by Cox regression analysis. RESULTS Efficacy of apatinib included partial response (PR) in 15 patients, stable disease (SD) in 86 patients, progressive disease (PD) in 27 patients. Therefore, ORR of the 128 patients with ES-SCLC was 11.7%, and disease control rate (DCR) was 78.9%. Prognosis suggested that the median progression-free survival (PFS) and overall survival (OS) of the 128 patients with ES-SCLC was 4.2 months and 8.2 months, respectively. The polymorphism analysis focusing on VEGFR2 gene indicated that one single nucleotide polymorphism 889C>T was of clinical significance. Prevalence of 889C>T among the 128 patients with SCLC were as follows: CC genotype 87 cases (68.0%), CT genotype 38 cases (29.7%) and TT genotype 3 cases (2.3%), the minor allele frequency of 889C>T was 0.17, which was in accordance with Hardy-Weinberg Equilibrium (P = 0.628). Patients with CT and TT genotypes were merged in the subsequent analysis. Prognosis analysis exhibited that the median PFS of patients with CT/TT genotype and CC genotype was 3.3 and 5.0 months, respectively (P = 0.02). Furthermore, the median OS of patients was 5.5 and 9.0 months, respectively (P = 0.008). Additionally, multivariate Cox regression analysis of OS demonstrated that CT/TT genotype was an independent factor for OS [Hazard ratio (HR) = 0.64, P = 0.019]. However, the safety profile according to genotype status of 889C>T failed to show significant difference. Interestingly, mRNA expression analysis suggested that the mRNA expression of VEGFR2 in cancer tissues were significantly different according to CC and CT/TT genotypes (P < 0.001). CONCLUSION The administration with apatinib for patients with chemotherapy-refractory ES-SCLC was of potential clinical significance. The clinical outcomes of patients with ES-SCLC who were treated with apatinib could be impacted by VEGFR2 889C>T polymorphism through mediating the VEGFR2 mRNA expression.

Angiotensin-converting enzyme inhibitors have adverse effects in anti-angiogenesis therapy for hepatocellular carcinoma. Cancer Lett 2020; 501:147-161. [PMID: 33383154 DOI: 10.1016/j.canlet.2020.12.031] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 12/03/2020] [Accepted: 12/21/2020] [Indexed: 12/14/2022]
Abstract
At present, anti-angiogenic drugs (AADs) are widely used in the systemic treatment of hepatocellular carcinoma (HCC) or other types of cancer, and have achieved good anti-cancer effect, whereas treatment-related proteinuria can affect the routine use of AADs, which in turn abates the overall efficacy. Currently, most clinicians prescribe angiotensin-converting enzyme inhibitors (ACEIs) to alleviate proteinuria according to diabetic nephropathy guidelines or expert recommendations. However, the efficacy of ACEIs in reducing AAD-related proteinuria and its effect on the anticancer effect of AADs is unknown. Our clinical data showed that some HCC patients experienced tumor progression by ACEIs administration for the treatment of proteinuria caused by AADs. Here, we confirmed that in different tumor-bearing mouse models, ACEIs did not delay the appearance of proteinuria or alleviate proteinuria caused by AADs but compromised the anticancer efficacy of AADs. This effect is unrelated to the change in the VEGF signaling pathway. Our data showed that the combination of ACEIs and AADs flared the production of kidney-derived erythropoietin (EPO). In turn, EPO compromises the anti-angiogenic effects of AADs and decreases antitumor activity. In conclusion, for the treatment of proteinuria caused by AADs, ACEIs have no efficacy while also promoting AADs resistance. This finding is of great significance to guide clinical standardized management of side effects of anti-angiogenic therapy for cancer patients.

Abstract
Purpose Effective treatment options for intrahepatic cholangiocarcinoma (ICC) are limited. This study was intended to explore the efficacy and safety of apatinib in advanced ICC with lymph node metastasis or distant metastasis. Patients and Methods The efficacy and toxicity of apatinib were evaluated in patients with ICC between November 2017 and March 2020 at the Second Affiliated Hospital of Anhui Medical University. Survival analysis was estimated using Kaplan–Meier method. Results Ten patients with advanced ICC were enrolled. The median progression-free survival (PFS) was 3.0 months (95% CI: 1.450–4.550). No patient achieved a complete response (CR). One patient gained partial response (PR), and 6 patients had stable disease (SD). The objective response rate (ORR) was 10%, and the disease control rate (DCR) was 70%. The common treatment-related adverse events were hypertension (20%), proteinuria (30%), hand and foot syndrome (10%) or emesis (10%). No grade 3/4 toxicities occurred. Toxicities were mild and tolerable. Conclusion Apatinib is potentially an effective treatment option with tolerable toxicities for patients with advanced ICC.

Abstract
Objective No effective and definitive chemotherapeutic regimen has been established in patients with non-small cell lung cancer (NSCLC) who failed second-line treatment. The aim of this study was to evaluate apatinib, a VEGFR-2 inhibitor, as monotherapy in elderly patients with advanced metastatic NSCLC. Methods We evaluated the efficacy and safety of apatinib in elderly patients (≥65 years old) with advanced metastatic NSCLC who failed second-line treatment from 2015 to 2016 in Huanggang Central Hospital. Survival analysis was performed by the Kaplan-Meier method. Toxicities were evaluated according to the National Cancer Institute Common Toxicity Criteria version 4.0. Results Twenty patients were included in the present study. Two patients achieved partial response, and 9 achieved stable disease, representing a response rate of 10% and a disease control rate of 55%. Median progression-free survival and overall survival were 2.8 and 6.0 months, respectively. The toxicities associated with apatinib were generally acceptable with a total grade 3/4 toxicity of 50%. Conclusion Apatinib is an optional choice as salvage treatment in elderly patients with advanced metastatic NSCLC, with modest efficacy and acceptable toxicities.

Abstract
Thyroid dysfunction has been previously reported during treatment with certain small-molecule multi-tyrosine kinase inhibitors, including sunitinib and sorafenib. Apatinib, which has a similar mechanism of action to these inhibitors, has reportedly induced hypothyroidism during treatment. Fully elucidating drug-associated adverse events could aid in patient monitoring and recommendations of suitable management strategies. The current 2-year observational study monitored patients with solid tumors who were prescribed apatinib. A total of 149 patients treated with apatinib from February 2015 to January 2016 were included. Their thyroid function and thyroid ultrastructure was evaluated for at least 24 months or until death. The primary objective of the current study was evaluating accepted thyroid replacement treatment. Secondary objective was ultrastructural changes in the thyroid gland. The current study was approved by the Medical Ethics Committee of Qianfoshan Hospital, affiliated with Shandong University and written informed consent was obtained from all patients prior to commencing the clinical trial. A total of 53 (35.57%) patients developed hypothyroidism, which varied from subclinical (12 cases; 8.05%) to clinical (41 cases; 27.52%). Thyroid nodules were noted in 15 cases (10.07%). Furthermore, 3 cases (2.01%) had thyroid imaging reporting and data system scores of 4a/4b/4c and 12 cases (8.05%) had scores of 1, 2 and 3. A total of 25 patients (16.78%) experienced 1-2 grade fatigue and 2 patients (1.34%) reported 3-4 grade fatigue. There was no reported association between disease control rate and hypothyroidism. Apatinib significantly increased the risk of clinically relevant hypothyroidism and altered thyroid gland structure.

The Efficacy and Safety of Apatinib in Refractory/Relapse Advanced Pediatric Solid Tumor: A Retrospective Study. Cancer Manag Res 2020; 12:6177-6185. [PMID: 32801866 PMCID: PMC7383017 DOI: 10.2147/cmar.s258689] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 07/02/2020] [Indexed: 11/23/2022] Open
Abstract
Background The prognosis of recurrent or refractory advanced childhood solid tumor patients is very poor and new therapeutic strategies are in urgent need. This study aimed to determine the efficacy and safety of apatinib in pediatric refractory/relapse advanced solid tumor patients. Patients and Methods The study retrospectively reviewed recurrent or refractory advanced pediatric solid tumor patients who were treated with apatinib, an oral small-molecule tyrosine kinase inhibitor (TKI) that targets vascular endothelial growth factor receptor-2 (VEGFR2), at the Sun Yat-sen University Cancer Center (China) from January 2016 to March 2019. Results Fifty-six patients were included in the safety evaluation and 49 patients were included in the efficacy evaluation. The objective responses rate (ORR) was 26.5% (95% CI 15–41): 0 CR (complete response) and 13 PR (partial response). Disease control rate (DCR) (CR+PR+SD) was 79.6% (95% CI 65–90). The median progression-free survival (PFS) was 4.0 months (95% CI 2.6–5.4). There was no significant difference for ORR or PFS between the A (apatinib monotherapy), A+MT (apatinib combined with oral metronomic therapy) and A+SC (apatinib combined with salvage combination chemotherapy) group (p>0.05). The most common grade 3 or 4 adverse events were neutropenia (9[16.1%]), thrombocytopenia (8[14.3%]), hand-foot syndrome (3[5.4%]), hypertension (3[5.4%]), anaemia (3[5.4%]) and mucositis (2[3.6%]). Hypertension was the most serious adverse event and one death that occurred was considered as drug-related. Conclusion Apatinib showed promising clinical activity in heavily treated recurrent or refractory advanced childhood solid tumor patients. However, it is necessary to pay special attention to monitoring blood pressure when using apatinib in children. Prospective randomized controlled clinical trial is warranted.

Abstract
Background Apatinib showed promising efficacy in the treatment of advanced or metastatic gastric cancer (mGC) in previous clinical studies. However, the real-world data are limited, and this study aimed to assess the effectiveness and safety of apatinib for the treatment of advanced or mGC in this setting. Methods In this prospective observational study, progression-free survival (PFS), overall survival (OS), overall response rate (ORR), disease control rate (DCR) and treatment-related adverse events (AEs) were recorded and evaluated. Univariate and multivariate analyses were conducted to explore potential biomarkers which might be related to the effectiveness. Results A total of 321 mGC patients from 47 centers in China were enrolled between July 1, 2015, and March 1, 2018. Thirty-two patients achieved partial response, 155 patients achieved stable disease, and 115 patients had progressive disease, and no CR was achieved, illustrating an ORR of 10.60% and a DCR of 61.92%. The median PFS and OS were 4.0 and 8.2 months, respectively. Multivariate Cox analysis showed that the potential biomarkers associated with longer PFS were combination regimens plus taxel/docetaxel, and apatinib initial dosage ≥500mg, occurrence of AEs of leukopenia, and hand-foot syndrome. Main AEs were proteinuria (17.1%), hypertension (15.9%), and handfoot syndrome (8.7%). Conclusion The present prospective observational study showed favorable effectiveness and safety of apatinib in real-world patients with advanced or metastatic GC in China. (A prospective, multi-center, non-intervention study of apatinib in the treatment of advanced gastric cancer-Trial Registry Number: ChiCTR-OPN-15006601).

Abstract
Bone and soft tissue sarcomas are rare malignant tumors originated from mesenchymal tissues. They harbor more than 50 distinct subtypes and differ in pathological features and clinical courses. Despite the significant improvements in modern multi-modality treatment, the outcomes and overall survival rates remain poor for patients with advanced, refractory, metastatic, or relapsed diseases. The growth and metastasis of bone and soft tissue sarcoma largely depend on angiogenesis, and VEGF/VEGFR pathway is considered as the most prominent player in angiogenesis. Therefore, blockade of VEGF/VEGFR pathways is a promising therapeutic strategy to retard neovascularization. Several VEGFR inhibitors have been developed and revealed their favorable anti-neoplastic effects in various cancers, but such desirable anti-tumor effects are not obtained in advanced sarcomas because of multiple reasons, such as drug tolerance, short duration of response, and severe adverse effects. Fortunately, preclinical and clinical studies have indicated that apatinib is a novel promising VEGFR2 inhibitor showing potent anti-angiogenic and anti-neoplastic activities in advanced sarcomas. Especially, apatinib has showed notable characteristics in multidrug resistance reversal, tumor regression, vascular normalization, immunosuppression alleviation, and enhancement of chemotherapeutic and radiotherapeutic effects. However, apatinib also gets struck in dilemma of reversing multidrug resistance of chemotherapeutic agents while suffering drug resistance itself, and several difficulties should be tackled before full use of apatinib. In this review, we discuss the outstanding characteristics and main predicaments of apatinib as targeted therapy in advanced sarcomas. Bone and soft tissue sarcomas are rare but malignant tumors originated from mesenchymal tissues. They harbor more than 100 distinct subtypes and differ in features of pathologies and clinical courses. Despite the significant improvements in modern multi-modality treatment, the outcomes and overall survival rates remain poor for patients with advanced, refractory, metastatic, or relapsed lesions. The growth and metastasis of bone and soft tissue sarcoma largely depend on angiogenesis and VEGF/VEGFR pathways play a pivotal role in angiogenesis. Therefore, blockade of VEGF/VEGFR pathways is a promising therapeutic strategy. Several VEGFR inhibitors have been developed and verified in clinical trials but with unfavorable outcomes. Fortunately, preclinical studies and clinical trials have indicated that apatinib is a novel promising VEGFR2 inhibitor showing potent anti-angiogenic and anti-neoplastic activities in advanced sarcomas. Actually, apatinib has showed notable characteristics in multidrug resistance reversal, tumor regression, vascular normalization, immunosuppression alleviation, enhancement of chemotherapeutic and radiotherapeutic effects. However, apatinib also gets struck in dilemma of reversing multidrug resistance of chemotherapeutic agents while suffering drug resistance itself, and several difficulties should be tackled before full use of apatinib. In this review, we discuss the outstanding characteristics and main predicaments of apatinib as targeted therapy in advanced sarcomas.

Abstract
Aim: To develop and validate a simple method using UPLC-MS/MS for determination of apatinib and its three active metabolites in a Phase IV clinical trial. Materials & methods: All compounds were separated on a Hypersil GOLD™ aQ C18 Polar Endcapped LC column (50 × 2.1 mm, 1.9 μm, Thermo) using 5 mmol/l ammonium acetate with 0.1% formic acid:acetonitrile (20:80, v/v) as the mobile phase after a rapid liquid-liquid extraction. This method was validated over the linear concentration range of 1.00-1000 ng/ml for each compound. Results: The interassay precision and accuracy were less than ±15%. The validated method was successfully applied to determine concentrations of clinical samples in non-small-cell lung cancer patients.

Abstract
OBJECTIVE Vascular permeability contributes to disease progression and drug resistance in hematological malignancies, including AML. Thus, targeting angiogenic signaling is a promising treatment strategy, especially for relapsed and resistant AML. The aim of this study was to evaluate the efficacy of apatinib, a novel receptor tyrosine kinase inhibitor that selectively targets VEGFR2. METHODS Several AML cell lines were exposed to various concentrations of apatinib, and then CCK8 and Annexin V/PI assays were performed to determine IC50 values and apoptosis, respectively. The effect of apatinib against primary AML cells from 57 adult patients and 11 normal controls was also analyzed utilizing an apoptosis assay. Next, we tested the underlying mechanism of apatinib in AML using western blotting and mass cytometry (CyTOF). Finally, the activity of apatinib against tumor growth and angiogenesis was further evaluated in vivo in xenograft models. RESULTS We found apatinib significantly inhibited growth and promoted apoptosis in AML cell lines in vitro. Similarly, apatinib showed cytotoxicity against primary AML cells but didn't affect normal BMMCs. Its effect was highly correlated with several clinical features, such as NPM1 mutation, extramedullary infiltration, relapsed/refractory disease, and M2 and M5 FAB subtypes. In addition, apatinib suppressed AML growth and attenuated angiogenesis in xenograft models. Mechanistically, apatinib-induced cytotoxicity was closely associated with inhibition of the VEGFR2-mediated Src/STAT3 and AKT/mTOR pathways and induction of mitochondria-mediated apoptosis. CONCLUSION Apatinib exerts antileukemia effects by targeting VEGFR2-induced prosurvival signaling and angiogenesis, thus providing a rationale for the application of apatinib in AML.

Experimental study of the vascular normalization window for tumors treated with apatinib and the efficacy of sequential chemotherapy with apatinib in lung cancer-bearing mice and patients. Cancer Med 2020; 9:2660-2673. [PMID: 32073228 PMCID: PMC7163088 DOI: 10.1002/cam4.2923] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 12/05/2019] [Accepted: 12/09/2019] [Indexed: 12/14/2022] Open
Abstract
In the tumor vascular system, the vascular structure is disordered, the morphology is abnormal, and the structure of the blood vessel walls is incomplete, leading to leakage of the blood vessel wall, elevated interstitial fluid pressure, and elevated blood flow resistance. These alterations lead to local microenvironmental changes, which mainly manifest as a lack of oxygen and acidosis, further affecting the efficacy of chemotherapy drugs. Antiangiogenic drugs can normalize the abnormalities caused by tumor angiogenesis, thereby transferring oxygen and drugs to tumor cells more efficiently through normalized blood vessels and enhancing the efficacy of chemotherapy drugs. Apatinib is a specific VEGFR‐2 inhibitor that blocks the transmission of the VEGF/VEGFR‐2 signaling pathway. In this study, we constructed a nude mouse xenograft model of lung cancer and administered apatinib at different doses and times to detect the normalization of reactive blood vessels through VEGF, α‐SMA, college‐IV, HIF‐1α, and MMP. The ultrastructure of tumor blood vessels was observed by electron microscopy, and the dose and timing of apatinib‐induced normalization of lung cancer in nude mice were confirmed. Then, we observed the inhibitory effect of apatinib combined with pemetrexed on transplanted tumors of lung cancer cells in nude mice at different time points and observed whether combination pemetrexed chemotherapy showed more significant effects in the time window of vascular normalization induced by apatinib. The inhibition of the growth of transplanted tumors was examined. Then 20 patients with advanced non–small cell lung cancer were enrolled, and apatinib sequential chemotherapy drugs were applied as a third‐line chemotherapy regimen to observe its clinical efficacy.

Abstract
Purpose This study investigated the clinical outcomes and safety of apatinib mesylate in the treatment of advanced non-squamous non-small cell lung cancer (NSCLC) in patients who progressed after standard therapy, and analyzed the kinase insert domain receptor (KDR) gene polymorphism. Methods A total of 135 patients with advanced non-squamous NSCLC who received apatinib mesylate were included. Objective response rates were evaluated. Subsequently, progression-free survival (PFS) and overall survival (OS) were assessed and safety data were recorded. Additionally, peripheral blood and biopsy cancer tissue specimens were collected from the patients with NSCLC for the genotyping of the genetic polymorphism and mRNA expression of the KDR gene, respectively. Analysis on the association between genotypes and prognosis was conducted. Results The objective response rate of the 135 patients with NSCLC was 18.52%, disease control rate was 65.19%, median PFS was 3.95 months, and median OS was 10.05 months. Regarding the KDR gene polymorphism analysis, the distribution of the 4397T>C polymorphism genotypes was in accordance with the Hardy–Weinberg Equilibrium (P=0.868). Moreover, the prognosis analysis indicated that the median PFS of patients with the CC/TC and TT genotypes was 2.80 and 4.80 months, respectively (P=0.002). Furthermore, the median OS of patients with the two genotypes was 9.10 and 10.56 months, respectively (P=0.041). The multivariate Cox regression analysis showed that the TC/CC genotypes were an independent factor for PFS (odds ratio: 1.72, P=0.009). There was no correlation between the polymorphism and adverse reactions. Additionally, the mRNA expression analysis suggested that the mRNA levels of KDR in cancer tissues were significantly different between the TT and TC/CC genotypes (P<0.001). Conclusion The clinical outcomes of treatment with apatinib mesylate for advanced non-squamous NSCLC in patients who progressed after standard therapy may be influenced by the KDR 4397T>C polymorphism through mediation of the mRNA expression of KDR.

Abstract
This clinical trial (ChiCTR1800019185) is designed to be an open‐label, prospective, single‐center, single arm exploratory research study. The study will recruit non‐small cell lung cancer patients (NSCLC) with slow progression after first‐line treatment with EGFR‐TKI drugs. Slow progression will be confirmed by the presence of serum carcinoembryonic antigen or imaging evaluation. The primary aim is to assess progression‐free survival after EGFR‐TKIs treatment combined with apatinib 250 mg once daily. The secondary objectives are to evaluate objective efficacy, disease control rates, quality of life, overall survival, and safety. From September 2018 to September 2020, under specific entry and discharge standards, we plan to enroll 38 eligible patients until the end of the study. We hope that our study will help to explore a new way of combining the small molecular inhibitors of antiangiogenesis with EGFR‐TKIs to overcome acquired drug resistance.

Abstract
Background: Recent trials of novel agents in 'rare' molecular subtypes of non-small cell lung cancer (NSCLC) have used single-arm trial designs and benchmarked outcomes against historical controls. We assessed the consistency of historical control outcomes using docetaxel data from published NSCLC randomized controlled trials (RCTs).Material and methods: Advanced NSCLC RCTs including a docetaxel monotherapy arm were included. Heterogeneity in tumor objective response rates (ORRs), progression-free survival (PFS) and overall survival (OS), and correlations between outcomes and year of trial commencement were assessed.Results: Among 63 trials (N = 10,633) conducted between 2000 and 2017, ORR ranged from 0% to 26% (I2 = 76.1%, pheterogeneity < .0001). Mean of the median PFS was 3.0 months (range: 1.4-6.4), 3-month PFS ranged from 25% to 85% (I2 = 86.0%, pheterogeneity < .0001). Mean of the median OS was 9.1 months (range: 4.7-22.9), 9-month OS ranged from 23% to 79% (I2 = 83.0%, pheterogeneity < .0001). Each later year of trial commencement was associated with 0.3% (p = .046), 0.5% (p = .11) and 0.9% (p = .001) improvement in ORR, 3-month PFS and 9-month OS rates, respectively.Conclusions: There was significant heterogeneity and an improving trend in docetaxel outcomes across trials conducted over 20 years. Benchmarking biomarker-targeted agents against historical controls may not be a valid approach to replace RCTs. Innovative study designs involving a concurrent control arm should be considered.

Abstract
The therapeutic regimen for small cell lung cancer (SCLC) has changed little in
the past several decades. Apatinib is a small molecule inhibitor of vascular
endothelial growth factor receptor-2 tyrosine kinase. Apatinib has demonstrated
efficacy against advanced gastric cancer and breast cancer, and recent studies
have also reported its successful use in non-SCLC; however, its efficacy in SCLC
remains unclear. In this study, we used apatinib as salvage therapy for
chemotherapy-refractory SCLC. Five male patients with advanced SCLC were
administered oral apatinib (250 mg/day) as 2nd- to 4th-line treatment. One
patient showed a partial response to apatinib, one showed stable disease, and
three patients showed progressive disease. The progression-free survival
durations in the patients with stable disease and partial response were 1.5 and
3 months, respectively. Only three patients showed adverse effects, including
mild hypertension, vomiting, and hand–foot syndrome, respectively, all of which
were manageable. Apatinib might thus be a salvage option in patients with
advanced SCLC after chemotherapy.

Abstract
Objective This study aimed to determine the efficacy and tolerability of apatinib plus dose-dense temozolomide (TMZ) as first-line treatment for recurrent glioblastoma (rGBM). Methods Patients with rGBM were enrolled in this study. Patients were subjected to concurrent treatment of apatinib (500 mg qd) and dose-dense TMZ (100 mg/m2, 7 days on with 7 days off) until disease progression or intolerable toxicity. Efficacy was evaluated using Response Assessment in Neuro-Oncology criteria for high-grade glioma. Safety was assessed using NCI-CTCAE 4.0. Survival was estimated with Kaplan–Meier curve and log rank test. Results From March 2016 to January 2018, 20 eligible patients who had relapsed from the standard chemoradiotherapy regimen (TMZ and radiotherapy) were enrolled in this study. The median follow-up time was 12 months. All patients were eligible for efficacy analysis. The objective response rate (ORR) was 45%. The disease control rate (DCR) was 90%. The median progress-free survival time was 6 months (95% CI, 5.3 to 7.8 months). The 6-month progression-free survival rate was 50%. The median overall survival was 9 months (95% CI, 8.2 to 12.2 months). The most common treatment-related adverse events were hypertension (21%), hand–foot syndrome (16%), leukopenia (14%), and thrombocytopenia (12%). Conclusion Apatinib combined with dose-dense TMZ was effective in terms of PFS, ORR, and DCR and was well tolerated after appropriate dose reduction in the Chinese population tested. Further randomized controlled clinical studies are needed to confirm the efficacy of apatinib combined with TMZ for treatment of rGBM.

Abstract
There were many clinical studies on lung cancer in 2018. In particular, significant progress has been made in immunotherapy and targeted therapy. Whether in small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC), immune checkpoint inhibitors (ICIs) have shown good results. For patients with specific gene mutations, the new generation inhibitors also showed good results in clinical trials. In this review, we summarize the clinical trials in lung cancer in 2018 and describe the progress and prospects for lung cancer therapies.

Abstract
Purpose Apatinib is effective and safe for several advanced or metastatic cancers, but its therapeutic value in cervical cancer is still unknown. The aim of the study was to assess the therapeutic value of apatinib in patients with chemo-refractory advanced cervical cancer. Patients and methods This was a retrospective study of patients with advanced cervical cancer treated with apatinib between April 2015 and December 2018 at the First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China. Patients had to have failed at least 2 lines of chemotherapy prior to receiving apatinib. The clinical tumor response was evaluated after 4 weeks of apatinib treatment, and then every 8 weeks (two cycles). Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and adverse events were evaluated. Results Twenty-five patients were included in this study. The median PFS was 5.8 months (95% CI, 4.65–6.95), and the median OS was 12.2 months (95% CI, 8.99–15.41). ORR was 48% and DCR was 96%. Complete response was not observed. The most common adverse events in this study (all grades) were hand-foot syndrome (48%), hypertension (20%), and mouth mucositis (20%). Conclusion Apatinib monotherapy showed good therapeutic value with tolerable adverse events for patients with chemo-refractory advanced cervical cancer.

Front Oncol 2019; 9:1180.

Abstract
Gallbladder carcinoma (GBC) is a relatively rare and aggressive malignant tumor with a poor prognosis. A systematic review of current clinical studies illustrates an extreme paucity of second-line therapeutic options following the failure of standard-of-care cisplatin-gemcitabine chemotherapy. The efficacy of apatinib, an highly potent and selective oral inhibitor of VEGFR-2 tyrosine kinase, for refractory advanced GBC has not yet been clarified. Herein, we report a case of advanced GBC that presented a durable partial response to apatinib used as monotherapy after the failure of multiline chemotherapies including S-1 monotherapy, capecitabine monotherapy, gemcitabine plus capecitabine, and irinotecan plus oxaliplatin. The patient achieved an efficacy of partial response within 2 months. By September 23, 2019, the duration of treatment had extended for almost 1 year with a satisfactory quality of life, and the administration of apatinib was continued. Dose reduction of apatinib occurred at week four due to grade 2 hypertension and hand-foot skin reaction (HFSR). No fatigue, proteinuria, mucositis, or thrombocytopenia occurred. To the best of our knowledge, this is the first case of a successful use of apatinib monotherapy for heavily pretreated GBC. Further prospective studies are warranted to confirm the efficacy and safety of apatinib in GBC.

Abstract
Apatinib, an oral small molecular receptor tyrosine kinase inhibitor (TKI) developed first in China, exerts antiangiogenic and antineoplastic function through selectively binding and inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we aimed to explore the efficacy and safety profile of apatinib monotherapy, or combined with chemotherapy or endothelial growth factor receptor (EGFR)-TKI in heavily pretreated non-small cell lung cancer (NSCLC) patients with brain metastases. We performed a retrospective analysis for relapsed NSCLC patients with brain metastases from our institute, who received apatinib (250 mg or 500 mg p.o. qd) monotherapy, or combination with EGFR-TKI or chemotherapy as second or more line systemic therapy until disease progression or unacceptable toxicity occurred. The objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and safety were analyzed. A total of 26 eligible patients were included: 24 patients diagnosed with adenocarcinoma, 2 with squamous carcinoma, and 14 patients harboring EGFR sensitizing mutations. The mPFS and mOS were 4.93 (range, 0.27–32.91; 95% CI 3.64–6.22) and 14.70 (range, 0.27–32.91; 95% CI 0.27–43.60) months for the whole group. The ORR and DCR were 7.7% (2/26) and 69.2% (18/26) for the entire lesions, and 7.7% (2/26) and 79.6% (20/26) for brain metastases, respectively. Compared with patients who received apatinib monotherapy, patients who received apatinib combination treatment had more favorable mPFS (11.77 vs. 2.27 months, p < 0.05) and mOS (24.03 vs. 6.07 months, p < 0.05). Treatment-related toxicities were tolerable including grade 1/2 hypertension, hand-and-foot syndrome, fatigue, nausea, liver dysfunction, myelosuppression, skin rash, and palpitation. In conclusion, apatinib exhibited high activity and good tolerance for NSCLC patients with brain metastasis, and it might become a potential choice for metastatic brain tumors in NSCLC patients.

Apatinib Mesylate in the treatment of advanced progressed lung adenocarcinoma patients with EGFR-TKI resistance -A Multicenter Randomized Trial. Sci Rep 2019; 9:14013. [PMID: 31570733 PMCID: PMC6768876 DOI: 10.1038/s41598-019-50350-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Accepted: 09/05/2019] [Indexed: 12/15/2022] Open
Abstract
Few pieces of evidence have been published on the use of Apatinib Mesylate (AM) against EGFR-TKI resistance in lung adenocarcinoma (LA) patients. Here, we investigate the clinical efficacy and safety of AM in the treatment of advanced progressed epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) resistant LA patients. We conducted a double-blind, randomized controlled trial in 68 patients admitted to 18 hospitals of Anhui province in China. The efficacy and safety of AM treatment were evaluated in terms of progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR), as well as related adverse events (AE). A literature knowledge database analysis and a pathway model reconstruction were performed to decipher the relevant mechanism may be involved. Our results showed that, compared to the control group, AM presented improved efficacy in PFS (P = 0.033), ORR (P < 0.001), and DCR (P < 0.001). No significant difference was observed between case and control group in terms of AE, and no drug-related death occurred. Pathway analysis supports that Apatinib can be repurposed for the treatment of LA. Our results suggested that AM could be a potential option for advanced progressed LA patients to combat EGFR-TKI resistance.

Abstract
Objective Anlotinib is an oral novel multi-target tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor, fibroblast growth factor receptor, platelet-derived growth factor receptor, and stem cell factor receptor (c-Kit). The aim of this study was to evaluate the efficacy and safety of anlotinib treatment in advanced lung cancer in the real world. Methods We evaluated the efficacy and toxicity of apatinib in patients with previously treated advanced lung cancer from 2018 to 2019 in Zhejiang Cancer Hospital. Survival analysis was performed by the Kaplan-Meier method. Results Fifty-eight patients were included in the present study. Thirty-one of these patients received anlotinib treatment as a third line and 27 patients received further therapy. All 58 patients had therapeutic evaluation and 46 patients acquired progression-free survival evaluation. Ten patients achieved partial response (PR), and 36 achieved stable disease (SD), representing a response rate of 17.2% and a disease control rate of 77.6%. Median progression-free survival was 3.3 months (95% CI 1.595-5.071). The toxicities associated with anlotinib were generally acceptable with a total grade 3/4 toxicity of 5.2%. The toxicities of anlotinib were generally tolerated and the common toxicities were hand-foot syndrome and hypertension. Conclusion In the third-line or more-line treatment of advanced lung cancer, anlotinib appears to have some activity when utilized as a salvage treatment. Adverse reactions are controllable.

Abstract
Lung cancer remains the leading cause of cancer-related deaths despite recent breakthroughs in immunotherapy. The widely embraced cancer stem cell (CSC) theory has also been applied for lung cancer, postulating that an often small proportion of tumor cells with stem cell properties are responsible for tumor growth, therapeutic resistance and metastasis. The identification of these CSCs and underlying molecular maintenance mechanisms is considered to be absolutely necessary for developing therapies for their riddance, hence achieving remission. In this review, we will critically address the CSC concept in lung cancer and its advancement thus far. We will describe both normal lung stem cells and their malignant counterparts in order to identify common aspects with respect to their emergence and regulation. Subsequently, the importance of CSCs and their molecular features in lung cancers will be discussed in a preclinical and clinical context. We will highlight some examples on how lung CSCs attain stemness through different molecular modifications and cellular assistance from the tumor microenvironment. The exploitation of these mechanistic features for the development of pharmacological therapy will also be discussed. In summary, the validity of the CSC concept has been evidenced by various studies. Ongoing research to identify molecular mechanisms driving lung CSC have revealed potential new cell intrinsic as well as tumor microenvironment-derived therapeutic targets. Although successfully demonstrated in preclinical models, the clinical benefit of lung CSC targeted therapies has thus far not been demonstrated. Therefore, further research to validate the therapeutic value of CSC concept is required.
