Respirology: Pharmacokinetics and safety of paclitaxel delivery into porcine airway walls by a new endobronchial drug delivery catheter

Tsukada H, Entcheva-Dimitrov P, Ernst A, Rafeq S, Keating JH, Seward KP, Yarmus L. Pharmacokinetics and safety of paclitaxel delivery into porcine airway walls by a new endobronchial drug delivery catheter.

Summary: Intratumoral administration of chemotherapeutic agents is a treatment modality that has proven efficacious in reducing the recurrence of tumours and increases specificity of treatment while minimizing systemic side effects. Direct intratumoral injection of malignant airway obstruction has potential therapeutic benefits but tissue drug concentrations and side-effect profiles are poorly understood. Results of these studies confirm the administration of PTX directly into the bronchial wall is safe and feasible. PTX was detectable in plasma for <7 days but tissue concentrations remained therapeutic throughout the follow-up period
