Vinflunine is a new vinca alkaloid uniquely fluorinated with the properties of mitotic-arresting and tubulin-interacting activity.Target: Microtubule/TubulinThe major effects of Vinflunine on dynamic instability are a slowing of the microtubule growth rate, an increase in growth duration, and a reduction in shortening duration. The effects of Vinflunine on the readmilling rate is examined by following [3H]GTP incorporation into MAP-rich microtubules, and the IC50 is 0.42 μM [1]. Vinflunine induced mitotic accumulation with IC50 with 18.8 nM, which decreases the centromere dynamicity by 44% and increases the time centromeres spent ina paused state by 63% [2]. Treatment of Vinflunine induces a rapid change in endothelial cell shape: cells retracts and assumes a rounded morphology. Mean IC50 values are 9.9 × 10-5 M × 10-5 M for fibronectin and 5.0× 10-5 M × 10-5 M for type IV collagen. A short 4 hours exposure of endothelial cells to Vinflunine at 10-8 0.05). An ID50 value (dose which inhibits 50% of bFGF-induced neovascularisation) is calculated as 1 mg/kg. Low doses of Vinflunine reduce the number of experimental liver metastases by human LS174T colon cancer cell. A slight overall decrease in liver metastatic foci is already observed at the very low dose of 0.16 mg/kg Vinflunine, although maximal overall inhibition is reached at the maximal tolerated dose (MTD) of 20 mg/kg [3].

Vinflunine
Drugs 2010 Jul 9;70(10):1283-93.PMID:20568834DOI:10.2165/11204970-000000000-00000.
Vinflunine is a novel bifluorinated vinca alkaloid that appears to differ from other class members in terms of its tubulin-binding properties and inhibitory effects on microtubule dynamics. Notably, it demonstrated superior in vivo antitumour activity to that of vinorelbine in a range of transplantable murine and human tumours. In a randomized, open-label, multicentre phase III trial in adult patients with advanced transitional cell carcinoma of the urothelium who experienced progression after first-line platinum-containing chemotherapy (n = 370), median overall survival (OS; primary endpoint) was 6.9 months for intravenous Vinflunine plus best supportive care (BSC) recipients versus 4.6 months for BSC alone recipients in the intent to treat (ITT) population. The difference in OS between treatment groups was not significant in the ITT population; however, there was a significant improvement in OS for Vinflunine plus BSC recipients in the ITT population after adjusting for prespecified prognostic factors, and in the analysis of the eligible population (ITT population excluding baseline protocol violations). In the latter, median OS was 6.9 months with Vinflunine plus BSC versus 4.3 months with BSC alone after a median follow-up of approximately 1.8 years and again after a median follow-up of approximately 3.6 years. Progression-free survival, objective response rate and disease control rate were significantly improved with Vinflunine plus BSC versus BSC alone. The most frequent treatment-related adverse events in Vinflunine recipients included myelosuppression (e.g. neutropenia) and gastrointestinal symptoms (e.g. constipation). In general, adverse events with Vinflunine were noncumulative and medically manageable.
Randomized phase III KEYNOTE-045 trial of pembrolizumab versus paclitaxel, docetaxel, or Vinflunine in recurrent advanced urothelial cancer: results of >2 years of follow-up
Ann Oncol 2019 Jun 1;30(6):970-976.PMID:31050707DOI:10.1093/annonc/mdz127.
Background: Novel second-line treatments are needed for patients with advanced urothelial cancer (UC). Interim analysis of the phase III KEYNOTE-045 study showed a superior overall survival (OS) benefit of pembrolizumab, a programmed death 1 inhibitor, versus chemotherapy in patients with advanced UC that progressed on platinum-based chemotherapy. Here we report the long-term safety and efficacy outcomes of KEYNOTE-045. Patients and methods: Adult patients with histologically/cytologically confirmed UC whose disease progressed after first-line, platinum-containing chemotherapy were enrolled. Patients were randomly assigned 1 : 1 to receive pembrolizumab [200 mg every 3 weeks (Q3W)] or investigator's choice of paclitaxel (175 mg/m2 Q3W), docetaxel (75 mg/m2 Q3W), or Vinflunine (320 mg/m2 Q3W). Primary end points were OS and progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) by blinded independent central radiology review (BICR). A key secondary end point was objective response rate per RECIST v1.1 by BICR. Results: A total of 542 patients were enrolled (pembrolizumab, n = 270; chemotherapy, n = 272). Median follow-up as of 26 October 2017 was 27.7 months. Median 1- and 2-year OS rates were higher with pembrolizumab (44.2% and 26.9%, respectively) than chemotherapy (29.8% and 14.3%, respectively). PFS rates did not differ between treatment arms; however, 1- and 2-year PFS rates were higher with pembrolizumab. The objective response rate was also higher with pembrolizumab (21.1% versus 11.0%). Median duration of response to pembrolizumab was not reached (range 1.6+ to 30.0+ months) versus chemotherapy (4.4 months; range 1.4+ to 29.9+ months). Pembrolizumab had lower rates of any grade (62.0% versus 90.6%) and grade ≥3 (16.5% versus 50.2%) treatment-related adverse events than chemotherapy. Conclusions: Long-term results (>2 years' follow-up) were consistent with those of previously reported analyses, demonstrating continued clinical benefit of pembrolizumab over chemotherapy for efficacy and safety for treatment of locally advanced/metastatic, platinum-refractory UC.

Vinflunine for the treatment of breast cancer
Expert Opin Pharmacother 2016 Sep;17(13):1817-23.PMID:27484180DOI:10.1080/14656566.2016.1217991.
Introduction: Breast cancer is the most frequently diagnosed cancer and the highest cause of cancer mortality in females worldwide. The development of drugs improving overall survival in late-stage metastatic breast cancer remains a challenge. Vinflunine is the most recently developed drug in the vinca alkaloid class. Its arrival has been eagerly awaited for treatment of solid tumors, and in particular, for metastatic breast cancer. Areas covered: The pharmacological features of Vinflunine are described. Its clinical development as monotherapy or in combination in metastatic breast cancer is detailed. A literature search on the topic was conducted through PubMed, clinical trials and the proceedings of the main cancer congresses. Expert opinion: The overall results from phase III studies, and in particular those that combined Vinflunine with capecitabine, have been less favorable. The combination's effectiveness was at best moderate compared with other drugs which also target metastatic breast cancer, and complicated by significant hematological and gastrointestinal adverse effects. Its use in advanced metastatic breast cancer cannot currently be recommended.
Vinflunine for the treatment of non-small cell lung cancer
Expert Opin Investig Drugs 2016 Dec;25(12):1447-1455.PMID:27771969DOI:10.1080/13543784.2016.1252331.
Vinflunine belongs to the class of vinca alkaloids and acts by disrupting the microtubule dynamics during cell cycle; this agent is currently available for previously treated advanced transitional cell carcinoma in Europe. The aim of this invited review is to evaluate the potential role of Vinflunine for the treatment of non-small cell lung cancer (NSCLC). Areas covered: The potential role of Vinflunine in NSCLC is discussed on the basis of the available data, including full papers and meeting abstracts. Relevant preclinical studies describing the pharmacological properties of Vinflunine are also included. The review also summarizes clinical studies, including phase I trials involving NSCLC among other tumors as well as phase II/III trials specifically addressing this malignancy. Additionally, the safety profile and the current regulatory status of Vinflunine is discussed. Expert opinion: Vinflunine is active as single agent and as part of platinum-based combinations in NSCLC. It results non-inferior to docetaxel in a randomized phase III trial including previously treated NSCLC patients; additionally, its safety profile is generally considered manageable. Ultimately, further studies are needed to confirm the role of Vinflunine in NSCLC, in consideration of the evolving evidence regarding targeted therapies and immune check-point inhibitors.

There is currently no curative treatment for advanced-stage or metastatic transitional cell carcinoma of the uretholial tract. Chemotherapy generally only prolongs survival by a few months. Cisplatin is often used, but there is no consensus protocol. Vinflunine, a fluorinated vinblastine derivative, has been tested in many types of cancer since the 1990s. It was finally authorised in the EU in 2009, but only for second-line treatment of urothelial carcinoma of the bladder. Clinical evaluation of Vinflunine in this setting is based on a single unblinded trial in 370 patients with treatment failure. It compared Vinflunine plus individually tailored palliative care versus palliative care alone. Vinflunine increased the median overall survival time by 2 months (from 4.6 months to 6.9 months), a difference that was not statistically significant in the protocol-specified primary analysis. Other analyses showed a significant difference, but the gain in survival was still only about 2 months, which is no better than with other cytotoxic drugs. Vinflunine has the same profile of adverse effects as other vinca alkaloids, including frequent, often serious and sometimes fatal haematological disorders, severe constipation, and ileus. Other adverse effects include QT prolongation and cardiac ischaemia. * In practice, Vinflunine has an unfavourable risk-benefit balance in patients with bladder cancer. It is better to continue to use better-assessed treatments.
