Clinical trial: Intrapleural Bevacizumab After Pleural Drainage in the Context of Breast Cancer

Summary: Metastatic pleural effusion is a common complication of late-stage cancer and reduces the quality of life and survival of patients. The survival of patients with recurrent pleurisy by uncontrolled local or systemic treatment is less than 6 months. It is important to develop specific therapies to improve the quality of life and survival of patients with metastatic pleurisy.
  Bevacizumab is a monoclonal anti vascular endothelial growth factor (VEGF) which has proven effective in many indications in oncology. Vascular endothelial growth factor (VEGF) is an angiogenic factor which increases endothelial permeability. It plays a central role in many tumors of epithelial origin. In this context, it is legitimate to ask whether an antiangiogenic targeting VEGF may be effective in patients with metastatic pleurisy by decreasing local blood supply and over-permeability.
  No study has been interested in the intra-pleural pharmacokinetics of monoclonal antibodies and there are no predictive or prognostic biomarkers for metastatic pleural effusions.
  The investigators believe that intrapleural administration of bevacizumab will reduce the pleural vasculature permeability. It will neutralize VEGF present in pleural fluid and reduce the replenishment of effusion due to its prolonged half-life of 21 days.
  The investigators therefore propose a phase I study to determine the maximum tolerated dose and the recommended dose for phases II, studying the pharmacokinetics of intrapleural bevacizumab administered by an implantable device after evacuating a symptomatic metastatic pleurisy as part of a mammary carcinoma. The VEGF intrapleural levels and serum will be study and the time until a new puncture. Dyspnea will be evaluated as well as its impact on quality of life.

  7. Contraindications to intrapleural administration of bevacizumab:
  -  Non-controlled arterial or venous thromboembolism
  -  Major surgery during the previous month or planned after study
  -  Known, non treated brain metastases
  -  Known hypersensitivity to bevacizumab or one of its excipients
  -  Hypersensitivity to Chinese hamster ovary cell (CHO) products or other human recombinant or humanized antibodies
  -  Intravenous administration of bevacizumab planned or underway in the usual cancer treatment (≥ 3 weeks wash out from the intrapleural injection)
  -  Radiotherapy including lung field concerned since the administration of the product until the end of the study.
  8. Diagnosis of any second malignancy within the last 5 years, except for basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix or breast) unless the subject has been free of the disease for > 3 years.
  9. Patients can't participate in another clinical trial with another experimental anti-cancer drug therapy simultaneously for 90 days. No exclusion period is required after the end of the trial visit.
  10. Impossibility to follow the calendar of exams because of geographic, social or psychological reasons.
