COVID-19 outbreak: An experience to reappraise the role of hospital at home in the anti-cancer drug injection.

BACKGROUND: The COVID-19 outbreak has posed considerable challenges to the health care system worldwide, especially for cancer treatment. We described the activity and the care organisation of the Hospitalisation At Home (HAH) structure during the pandemic for treating patients with anti-cancer injections. METHODS: We report the established organisation, the eligibility criteria, the patient characteristics, the treatment schemes and the stakeholders' role during two 5-week periods in 2020, before and during the French population's lockdown. RESULTS: The increase of activity during the lockdown (+32% of treated patients, +156% of new patients and +28% of delivered preparations) concerned solid tumour, mainly breast cancer, even if haematological malignancies remained the most frequent. Thirty different drugs were delivered, including three new drugs administered in HAH versus 19 during the routine period (p < 0.01). For those clinical departments accustomed to using HAH, the usual organisation was kept, but with adjustments. Five clinical departments increased the number of patients treated at home and widened the panel of drugs prescribed. Three oncology departments and one radiotherapy department for the first time solicited HAH for anti-cancer injections, mainly for immunotherapy. We adjusted the HAH organisation with additional human resources and allowed to prescribe drugs with an infusion time of <30 min only for the new prescribers. CONCLUSION: HAH allowed for the continuation of anti-cancer injections without postponement during the pandemic, and for a decrease in unnecessary patient travel to hospital with its concomitant COVID-19 transmission risk. Often left out of guidelines, the place of HAH in treating cancer patients should be reappraised, even more so during a pandemic.

How to manage intravenous vinflunine in cancer patients with renal impairment: results of a pharmacokinetic and tolerability phase I study.

AIMS: Vinflunine (VFL) ditartrate, a novel tubulin-targeted inhibitor, is registered for the treatment of patients with advanced or metastatic urothelial transitional cell carcinoma. This phase I study assessed the effect of renal impairment on the pharmacokinetics and tolerability of VFL. METHODS: VFL was infused in patients with advanced/metastatic solid tumours once every 3 weeks with anticipated dose reduction on the first cycle stratified according to the creatinine clearance (CLcr ) values. Pharmacokinetic data were collected on the first two cycles in renally impaired patients (CLcr ≤ 60 ml min(-1) ) and were compared with a control cohort of patients (CLcr > 60 ml min(-1) ). RESULTS: Thirty-three patients (46-86 years) were treated, 13 in group 1 (40 ml min(-1) ≤ CLcr ≤ 60 ml min(-1) ) and 20 in group 2 (20 ml min(-1) ≤ CLcr < 40 ml min(-1) ). The renal dysfunction induced a mean decrease in VFL clearance of 12% in group 1 and 28% in group 2, compared with the control group. The anticipated dose reduction given in renally impaired patients (i.e. 280 mg m(-2) and 250 mg m(-2) in groups 1 and 2, respectively) yielded similar drug exposure to control patients. The tolerance profile of VFL in patients with renal dysfunction was similar to that observed in patients with CLcr > 60 ml min(-1) . CONCLUSION: In conclusion, the recommended doses of intravenous VFL administered once every 3 weeks in cancer patients with renal impairment are 280 mg m(-2) when CLcr is between 40 and 60 ml min(-1) and 250 mg m(-2) when CLcr is between 20 and <40 ml min(-1) .

Phase II study of intravenous vinflunine after failure of first-line vinorelbine based regimen for advanced breast cancer.

PURPOSE: This open label phase II study evaluated the safety and efficacy of vinflunine in patients with breast cancer previously treated with a vinorelbine-based regimen and who progressed during or within 6 months of completing this chemotherapy. PATIENTS AND METHODS: Thirty eight patients received vinflunine 320 mg/m(2) once every 3 weeks. The primary efficacy endpoint was overall response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and safety. RESULTS: ORR was 8.3% (95% CI: 1.75-22.4) and DCR was 75% (95% CI: 57.8-87.9). PFS was 4.0 months (95% CI: 2.5-6.1) and OS was 13.6 months (95% CI: 8.7-18.9). Toxicities not hampering dose intensity were as expected neutropenia (75.6% of patients), fatigue (44.7%), constipation (28.9%) and abdominal pain (26.3%). CONCLUSION: Vinflunine demonstrated antitumour activity and can be safely administered in breast cancer patients refractory/resistant to vinorelbine.

Phase I and pharmacokinetic study of IV vinflunine in combination with carboplatin in chemonaive patients with advanced non-small cell lung cancer.

OBJECTIVE: Vinflunine (VFL) (Javlor(®)), a novel fluorinated semisynthetic vinca alkaloid has shown significant antitumor activity in advanced non-small cell lung cancer (NSCLC). We propose to define the recommended dose (RD) of VFL in combination with carboplatin in advanced NSCLC patients. METHODS: This phase I and pharmacokinetic study was designed to determine the maximum tolerated dose and to establish the RD of VFL in combination with carboplatin. Twenty-one chemonaive patients with advanced NSCLC were treated with a first-line chemotherapy of VFL and carboplatin both given on day 1 every 3 weeks with 3 dose levels. RESULTS: Five patients experienced a dose limiting toxicity consisting of constipation in 2 patients and febrile neutropenia in 2 patients. One patient experienced grade 3 abdominal pain concurrent with grade 4 neutropenia. The combination of VFL (320 mg/m(2)) and carboplatin AUC6 was defined as the maximum tolerated dose. The RD was established at the dose of VFL (320 mg/m(2)) combined with carboplatin AUC5. At the RD, 12 patients received a median number of 3 cycles of the combination. Neither VFL nor carboplatin seemed to be influencing the pharmacokinetics of the other. Among 19 patients evaluable for tumor response, 7 had a partial response and 7 experienced stable disease. CONCLUSIONS: The combination of VFL (320 mg/m(2)) and carboplatin AUC 5 given once every 3 weeks is established as the RD of the combination, which was shown to be active in these chemonaive NSCLC patients.

Phase I and pharmacokinetic study of IV vinflunine in combination with gemcitabine for treatment of advanced non-small cell lung cancer in Chemonaive patients.

INTRODUCTION: Vinflunine (Javlor) has shown significant antitumour activity in advanced non-small cell lung cancer (NSCLC). We propose to define the recommended dose of vinflunine in combination with gemcitabine for treatment of advanced NSCLC in chemonaive patients. METHODS: A phase I and pharmacokinetic study was conducted to determine the maximum tolerated dose and to establish the recommended dose of vinflunine (VFL) administered on day 1 every 21 days combined with gemcitabine given on days 1 and 8 every 3 weeks. RESULTS: Nineteen patients were included in this study. Three patients experienced a dose limiting toxicity, with constipation in one patient, hypertension in one patient, and constipation and febrile neutropenia in one patient. The combination of VFL 320 mg/m² and gemcitabine 1250 mg/m² was defined as the maximum tolerated dose. The recommended dose was established at the dose of VFL 320 mg/m² combined with gemcitabine 1000 mg/m². Neither VFL nor gemcitabine seemed to be influencing the pharmacokinetics of each other. All patients were evaluable for tumor response. Seven presented a partial response and eight experienced a stable disease. CONCLUSIONS: The combination of VFL 320 mg/m² administered on day 1 combined with gemcitabine 1000 mg/m² given on days 1 and 8 every 3 weeks is established as the RD and was shown to be active in these chemonaive NSCLC patients.

Phase I/II and pharmacokinetic study of intravenous vinflunine in combination with cisplatin for the treatment of chemonaive patients with advanced non-small-cell lung cancer.

BACKGROUND: A multicenter phase I/II trial of vinflunine administered in combination with cisplatin at 80 mg/m(2) was conducted in order to determine the dose-limiting toxicities, the maximum tolerated dose, and the recommended dose of the combination. An eventual mutual pharmacokinetic drug-drug interaction when vinflunine and cisplatin were coadministered was also evaluated. The study was also intended to define the response rate of vinflunine in combination with cisplatin as first-line chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC) at the recommended dose. PATIENTS AND METHODS: Patients were required to have a histologically confirmed diagnosis of NSCLC not amenable to curable treatment or stage IV disease. Patients may have had previous surgery for NSCLC but were to be chemonaive and have at least 1 bidimensional measurable lesion outside an irradiated area. RESULTS: The recommended dose was established at cisplatin 80 mg/m2 combined with vinflunine 320 mg/m(2). No unexpected adverse events were seen. Pharmacokinetic analysis supported the absence of mutual pharmacokinetic interaction when vinflunine and cisplatin are given in combination. Treatment of 53 patients at this recommended dose demonstrated a tumor response rate of 32.1% in the intent-to-treat population; disease control was achieved in 79.2% of the patients. The median progression-free survival and overall survival were estimated at 5 months and 10.4 months, respectively, and the 1-year survival rate was 43.4%. CONCLUSION: These results place the vinflunine/cisplatin combination among the most active doublets in this treatment setting and warrant further development in phase III trials of first-line treatment of patients with advanced metastatic NSCLC.

Phase II study of vinflunine in malignant pleural mesothelioma.

PURPOSE: Malignant pleural mesothelioma (MPM) is a disease of increasing incidence for which treatment options are limited. This study reports the clinical efficacy data for vinflunine, a novel microtubule inhibitor, in MPM. PATIENTS AND METHODS: Patients with a histologically confirmed diagnosis of MPM were eligible for enrollment onto this multicenter phase II trial if they had not received prior chemotherapy or radiotherapy and had measurable lesions by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Vinflunine 320 mg/m2 by 10-minute intravenous infusion was administered on day 1 of 21-day cycles. Modifications of dose and schedule were made according to National Cancer Institute Common Toxicity Criteria version 2.0. Efficacy was assessed by an external, independent radiologist. The one-sample multiple testing procedure of Fleming was applied at the predetermined recruitment stages of 20 and 40 assessable patients. RESULTS: Sixty-seven patients were enrolled. Five patients were not assessable for tumor response. The response rate was 13.8% (95% CI, 6.5% to 24.7%). The median survival was 10.8 months (95% CI, 7.8 to 12.0 months). The most common adverse events were anemia, neutropenia, fatigue, constipation, and nausea. Of grade 3 and 4 toxicities, neutropenia and constipation were the most common (45% and 9% of patients, respectively). CONCLUSION: Vinflunine can be delivered with high-dose intensity in patients with MPM. The response rate and median survival are encouraging for a single agent. These data suggest that vinflunine should be further evaluated in the management of MPM.

Phase I study of vinflunine administered as a 10-minute infusion on days 1 and 8 every 3 weeks.

Vinflunine is a novel vinca alkaloid developed through the selective modification of vinorelbine using super-acidic chemistry. In preclinical testing, vinflunine demonstrated significantly enhanced anti-tumour activity in human tumour xenograft models when compared to its parent compound. A phase I study was conducted to evaluate the safety and toxicity of vinflunine administered as a 10 minute intravenous infusion on days 1 and 8 every three weeks. Sixteen patients with advanced solid tumours were treated. Two of four patients experienced dose limiting toxicities (DLT) at 190 mg/m2 and this was established as the maximum tolerated dose (MTD). At the MTD, the DLT of vinflunine consisted of constipation and neutropenia. Fatigue was notable but not dose limiting. No objective responses were observed. A dose of 170 mg/m2 given on a day 1 and 8 schedule every three weeks would be suitable for future studies.

Vinflunine: a novel antitubulin agent in solid malignancies.

Vinflunine is the first bi-fluorinated, tubulin-targeted agent that was obtained by semisynthesis using super-acidic chemistry, which allowed the selective introduction of two fluorine atoms at the C20' position of vinorelbine. This compound has been selected for clinical development on the basis of promising preclinical activity that warranted a study in patients with a wide spectrum of solid tumours. Clinically significant activity was seen in the Phase II studies for the treatment of bladder, non-small cell lung and breast cancers, thus prompting the initiation of the Phase III trials that are currently ongoing.
