Currently, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) were approved for the treatment of non-small cell lung cancer (NSCLC) patients harboring EGFR mutation. However, some lung cancer patients fail to respond and eventually develop drug resistance. Therefore, new therapeutic strategies are needed to improve the outcomes for substantial clinical benefit. Here we aimed to explore the combination of vinorelbine with the second EGFR-TKI afatinib in NSCLC cells with or without EGFR mutation. The three cells of H1975, HCC827, and H460 were assessed for the combination of vinorelbine and afatinib. Vinorelbine combined with afatinib synergistically inhibited the three lung cancer cells growth without aggravating adverse effect on the normal lung cells. The combination of low doses of vinorelbine and afatinib suppressed the cancer cell proliferation by cell colony formation assay and significantly induced cell apoptosis. The anti-apoptotic proteins Bcl-xL and Bcl-2 showed significant reduction after the drug combination treatment, while the pro-apoptotic protein Bax as well as apoptosis indicators cytochrome C and cleaved PARP were observed a notable increasing. EGFR downstream pathways including AKT, ERK, JNK, and p38 were highly active and p53 was inactive in the three lung cancer cells, favoring tumor growth. The low doses of vinorelbine plus afatinib blocked the phosphorylation of AKT, ERK, JNK, and p38, but restored the expression of p53. Our findings suggested that the combination of vinorelbine and afatinib could be recommended as a therapeutic regimen for treatment of NSCLC with or without EGFR mutation.

Vinorelbine, the standard chemotherapy drug on advanced lung cancer, causes adverse events such as immunosuppression and bone marrow suppression. Thus, it is necessary to find drugs that could improve immune function and synergistically enhance the anti-tumor effect of vinorelbine. Thymosin is reported to inhibit tumor growth as an immunomodulator. Herein, to study the synergistic anti-cancer and attenuation effects of thymosin on vinorelbine, human lung cancer A549 cells that were labeled with CM-DiI were transplanted into zebrafish to establish the lung cancer xenotransplanted model. After treatment of vinorelbine and different concentrations of thymosin, the fluorescence intensity of CM-DiI-labeled A549 cells and the number of apoptotic muscle cells in the tumor-bearing zebrafish were detected. Besides, effects of thymosin on vinorelbine-reduced macrophages and T cells were identified in the transgenic zebrafish (Tg:zlyz-EGFP and Tg:rag2-DsRed). Then, the qRT-PCR was used to determine the alterations of the immune-related factors at the transcription level. Thymosin showed a marked synergistic anti-cancer effect with vinorelbine for the xenograft human lung cancer A549 cells, and the synergistic effect enhanced in a dose-dependent manner. Moreover, thymosin alleviated vinorelbine-induced muscle cell apoptosis, macrophage reduction, and T cell suppression. Compared with the vinorelbine group, co-administration with thymosin raised the mRNA levels of TNF-α, TNF-β, INF-γ, and GM-CSF. Thus, thymosin possesses synergistic anti-cancer effect on vinorelbine, and has protective effect on vinorelbine-induced immunosuppression. Thymosin, as an adjuvant immunomodulatory therapy, has great potential in enhancing the clinical application of vinorelbine.

Combined use of apatinib mesylate and vinorelbine versus vinorelbine alone in recurrent or metastatic triple-negative breast cancer: study protocol for a randomized controlled clinical trial.
BACKGROUND
The emergence of new molecular targeted drugs provides new prospects for the treatment of advanced breast cancer; the future therapeutic trend includes chemotherapy combined with molecular targeted therapy. Apatinib mesylate, a novel, small anti-angiogenic agent, highly selectively inhibits the activity of vascular endothelial growth factor receptor-2 tyrosine kinase. Apatinib mesylate also blocks the signaling of vascular endothelial growth factor binding to its receptor, thereby strongly inhibiting tumor angiogenesis and exerting an anti-tumor effect. However, there have been no reports of a randomized controlled clinical trial of apatinib combined with vinorelbine for the treatment of triple-negative breast cancer (TNBC). We will compare the therapeutic effect of vinorelbine alone or in combination with apatinib mesylate, in patients with recurrent or metastatic TNBC in North China who have received at least two drug treatments, including anthracyclines and taxanes.
METHODS/ANALYSIS
This study is a triple-blind, randomized, placebo-controlled, parallel-group clinical trial. We plan to include 238 female patients with locally recurrent or metastatic TNBC, admitted to the Liaoning Cancer Hospital & Institute, Northeast China. All enrolled patients will be randomized to oral vinorelbine alone (40 mg, thrice a week (Mondays, Wednesdays, and Fridays) in each 3-week cycle), or in combination with oral apatinib mesylate (500 mg, once daily in each 3-week cycle). Radiographic assessment will be performed every 6 weeks for 36 weeks and every 9 weeks thereafter. The primary outcome is progression-free survival and secondary outcomes include overall survival, disease control rate, objective response rate, and incidence of adverse events at grades 3 and 4, as defined by the National Cancer Institute Common Toxicity Criteria Version 4.0. Outcome measures will be evaluated at baseline (< 2 weeks before starting treatment), every 6 weeks during treatment, and at 4 weeks and every 3 months after treatment discontinuation.
DISCUSSION
Based on the data from this trial, we hope to identify a treatment plan that is suitable for female patients with TNBC, who have been treated with anthracyclines and taxanes, in Northeast China.

Clinical Trial
INTRODUCTION
The objective of this study was to evaluate the efficacy and safety of eribulin monotherapy, relative to vinorelbine, in Chinese women with locally recurrent/metastatic breast cancer (MBC).
METHODS
This phase III open-label, randomised, parallel-group, multicentre clinical trial enrolled patients with locally recurrent or MBC who had had 2-5 prior chemotherapy regimens, including an anthracycline and taxane) from September 26, 2013, to May 19, 2015. Women were randomised 1:1 to receive eribulin (1.4 mg/m, intravenously, on day 1 and day 8) or vinorelbine (25 mg/m, intravenously, on day 1, day 8 and day 15) every 21 days. The primary end-point was progression-free survival (PFS). Secondary end-points included objective response rate (ORR), duration of response and overall survival (OS).
RESULTS
Five hundred thirty women were randomised to receive eribulin (n = 264) or vinorelbine (n = 266). Improvement in PFS was observed with eribulin compared with vinorelbine (hazard ratio [HR]: 0.80, 95% confidence interval [CI]: 0.65-0.98, P = 0.036); median PFS was 2.8 months in both treatment arms. The median OS was 13.4 months with eribulin and 12.5 months with vinorelbine (HR: 1.03, 95% CI: 0.80-1.31, P = 0.838). The ORR was 30.7% (95% CI: 25.2%-36.6%) with eribulin and 16.9% (95% CI: 12.6%-22.0%) with vinorelbine (P < 0.001). Treatment-emergent adverse events leading to treatment discontinuation were less frequent with eribulin (7.2%) than with vinorelbine (14.0%).
CONCLUSIONS
Eribulin achieved statistically significantly superior PFS (and response rate) compared with vinorelbine in previously treated women with locally recurrent or MBC. Eribulin appeared to be better tolerated than vinorelbine, with no new safety signals observed.

A phase II study of a doublet metronomic chemotherapy regimen consisting of oral vinorelbine and capecitabine in Chinese women with HER2-negative metastatic breast cancer.
BACKGROUND
This single-arm prospective phase II trial was performed to assess the efficacy and safety of the dual oral metronomic vinorelbine and capecitabine (mNC) regimen in women with HER2-negative metastatic breast cancer (MBC) in China.
METHODS
The mNC regimen was administered to the enrolled cases, including oral vinorelbine (VNR) 40 mg three times weekly (on days 1, 3 and 5 every week) and capecitabine (CAP) 500 mg three times a day, until disease progression or intolerable toxicity. The primary endpoint was the 1-year progression-free survival (PFS) rate. Secondary endpoints included objective response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR) and treatment-related adverse events (TRAEs). Stratified factors included treatment lines and hormone receptor (HR) status.
RESULTS
Between June 2018 and March 2023, 29 patients were enrolled into the study. The median follow-up time was 25.4 months (range, 2.0-53.8). In the entire group, the 1-year PFS rate was 54.1%. ORR, DCR and CBR were 31.0%, 96.6% and 62.1%, respectively. The mPFS was 12.5 months (range, 1.1-28.1). Subgroup analysis revealed that ORRs were 29.4% and 33.3% in first- and ≥second-line chemotherapy, respectively. ORRs were 29.2% (7/24) and 40.0% (2/5) for HR-positive MBC and metastatic triple-negative breast cancer (mTNBC), respectively. Grade 3/4 TRAEs were neutropenia (10.3%) and nausea/vomiting (6.9%).
CONCLUSIONS
The dual oral mNC regimen showed very good safety features and improved compliance without loss of efficacy in both first- and second-line treatments. The regimen also reached an excellent ORR in the mTNBC subgroup.

Vinorelbine is a semisynthetic vinca alkaloid used in the treatment of advanced breast and non-small cell lung cancers. Vincristine, a related vinca alkaloid, is 9-fold more efficiently metabolized by CYP3A5 than by CYP3A4 in vitro. This study quantified the relative contribution of CYP3A4 and CYP3A5 to the metabolism of vinorelbine in vitro using cDNA-expressed human cytochrome P450s (P450s) and human liver microsomes (HLMs). CYP3A4 and CYP3A5 were identified as the P450s capable of oxidizing vinorelbine using a panel of human enzymes and selective P450 inhibitors in HLMs. For CYP3A4 coexpressed with cytochrome b5 (CYP3A4+b5) and CYP3A5+b5, the Michaelis-Menten constants for vinorelbine were 2.6 and 3.6 μM, respectively, but the Vmax of 1.4 pmol/min/pmol was common to both enzymes. In HLMs, the intrinsic clearance of vinorelbine metabolism was highly correlated with CYP3A4 activity, and there was no significant difference in intrinsic clearance between CYP3A5 high and low expressers. When radiolabeled vinorelbine substrate was used, there were clear qualitative differences in metabolite formation fingerprints between CYP3A4+b5 and CYP3A5+b5 as determined by NMR and mass spectrometry analysis. One major metabolite (M2), a didehydro-vinorelbine, was present in both recombinant and microsomal systems but was more abundant in CYP3A4+b5 incubations. We conclude that despite the equivalent efficiency of recombinant CYP3A4 and CYP3A5 in vinorelbine metabolism the polymorphic expression of CYP3A5, as shown by the kinetics with HLMs, may have a minimal effect on systemic clearance of vinorelbine.

Effective reinduction regimens are needed for children with relapsed and refractory acute myeloid leukemia (AML), as outcomes remain poor. Therapeutic options are limited in this heavily pretreated patient population, many of whom have reached lifetime recommended doses of anthracycline chemotherapy. The development of effective non-anthracycline-based salvage regimens is crucial to these patients who are at significant risk of life-threatening cardiotoxicity. We previously reported results of a phase 2 trial of a clofarabine-based regimen with topotecan, vinorelbine, and thiotepa (TVTC) in patients with relapsed acute leukemias. Here we report on an expanded bicenter cohort of 33 patients, <25 years of age, with relapsed/refractory AML treated with up to 2 cycles of the TVTC reinduction regimen from 2007 to 2018. The overall response rate, defined as complete remission or complete remission with partial recovery of platelet count, was 71.4% (95% confidence interval [CI], 41.9-91.6) for those patients in first relapse (n = 14) and 47.4% (95% CI, 24.4-71.1) for patients in second or greater relapse or with refractory disease. Responses were seen across multiple high-risk cytogenetic and molecular subtypes, with 84% of responders successfully bridged to allogeneic stem cell transplantation. The 5-year overall survival for patients in first relapse was 46.2% (95% CI, 19.1-73.3) and 50.0% (95% CI, 26.9-73.1) for patients who responded to TVTC. For pediatric and young adult patients with relapsed/refractory AML, TVTC reinduction compares favorably with currently used salvage regimens and warrants further exploration.

Clinical Trial
To determine the recommended phase II dose of vinorelbine in combination with cisplatin and thoracic radiotherapy (TRT) in patients with unresectable stage III non-small cell lung cancer (NSCLC), 18 patients received cisplatin (80 mg/m2) on day 1 and vinorelbine (20 mg/m2 in level 1, and 25 mg/m2 in level 2) on days 1 and 8 every 4 weeks for 4 cycles. TRT consisted of a single dose of 2 Gy once daily for 3 weeks followed by a rest of 4 days, and then the same TRT for 3 weeks to a total dose of 60 Gy. Fifteen (83%) patients received 60 Gy of TRT and 14 (78%) patients received 4 cycles of chemotherapy. Ten (77%) of 13 patients at level 1 and all 5 patients at level 2 developed grade 3-4 neutropenia. Four (31%) patients at level 1 and 3 (60%) patients at level 2 developed grade 3-4 infection. None developed > or = grade 3 esophagitis or lung toxicity. Dose-limiting toxicity was noted in 33% of the patients in level 1 and in 60% of the patients in level 2. The overall response rate (95% confidence interval) was 83% (59-96%) with 15 partial responses. The median survival time was 30.4 months, and the 1-year, 2-year, and 3-year survival rates were 72%, 61%, and 50%, respectively. In conclusion, the recommended dose is the level 1 dose, and this regimen is feasible and promising in patients with stage III NSCLC.

BACKGROUND
The MILES and ELVIS studies showed that vinorelbine is one of the best options for elderly patients with advanced non-small-cell-lung cancer (NSCLC). Oral vinorelbine at standard schedule (60-80 mg/m/weekly) has good activity in terms of response rates and progression-free survival. In recent years, a metronomic schedule of oral vinorelbine (40-50 mg/m three times a week, continuously) has been studied in phase II trials, especially in unfit and elderly patients. In the MOVE trial metronomic oral vinorelbine had a clinical benefit [partial response (PR)+stable disease (SD) >12 weeks] in 58.1% of patients with mild toxicity. On this basis, in 2017 we started a phase II study with metronomic oral vinorelbine in elderly (over 70 years) or unfit [Eastern Cooperative Oncology Group performance score (ECOG-PS) of 2] patients with locally/advanced and metastatic NSCLC. Primary aims were clinical benefit (PR+SD ≥6 months) and toxicity; secondary aims were progression-free survival and overall survival.
PATIENTS AND METHODS
A total of 25 patients entered the study: 11 with local/advanced and 14 with metastatic NSCLC (five squamous and 20 adenocarcinoma). None of the patients had epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) translocation, or programmed death ligand 1 (PDL1) expression; those with squamous carcinoma did not have PDL1 expression. The median age was 79 (range=44-90) years. The PS was 0 in 12 patients (48%), 1 in four patients (16%) and 2 in nine patients (36%). Oral vinorelbine was administered at 40 mg three times a week continuously.
RESULTS
Clinical benefit was achieved in eight patients (32%). Objective responses were partial response in two patients (8%), stable disease in seven (28%), progressive disease in nine (36%); seven patients were not evaluable for response (28%). Median progression-free survival was 2 months; median overall survival was 4 months but four out of eight patients with clinical benefit were still alive at 18 months. Overall survival at 1 year was 32%. Toxicity was mild: only one patient experienced grade 4 neutropenia, one grade 3 peripheral neuropathy, four grade 2 asthenia, one grade 2 mucositis, and one grade 2 diarrhoea. The dose needed to be reduced to 30 mg/m/three times a week in three patients.
CONCLUSION
Our study confirmed the activity and safety of metronomic oral vinorelbine in patients with wild-type local/advanced and metastatic NSCLC unsuitable for treatment with standard i.v. chemotherapy, allowing patients a comfortable home-based therapy, thereby avoiding frequent hospital visits.

Anaplastic thyroid cancer (ATC) is a rare neoplasia with a poor prognosis. Proliferation and apoptosis assays were performed on ATC cell lines (8305C, 8505C) exposed to vinorelbine, lenvatinib, as well as to concomitant combinations. ABCB1, ABCG2 and CSF-1 mRNA expression was evaluated by real time PCR. The relative levels of pospho Akt were investigated as part of a human phospho-kinase array analysis, and CSF-1 and VEGFR-2 protein levels were measured by ELISA. The intracellular concentration of lenvatinib in ATC cells was measured by combined reversed-phase liquid chromatography-tandem mass spectrometry. An ATC subcutaneous xenograft tumor model in nude mice was treated with vinorelbine, lenvatinib, or vinorelbine plus lenvatinib. After treatment with vinorelbine, lenvatinib, a significant antiproliferative effect in ATC cell lines was observed. The concomitant treatment of vinorelbine and lenvatinib revealed synergism for all the fractions of affected cells. A decrease in ABCB1 expression was reported in both ATC cell lines treated with the lenvatinib plus vinorelbine combination, as was an increase in the intracellular concentration of lenvatinib. The combination caused a decrease in Akt, GSK3α/β, PRAS40 and Src phosphorylation, and in both CSF-1 mRNA and protein levels. In the subcutaneous tumor model, the combination reduced the tumor volume during the treatment period. Our results establish the synergistic ATC antitumor activity of a vinorelbine and lenvatinib combination.
