Abstract:
INTRODUCTION:Picoplatin was developed as platinum coordination complex to overcome development of resistance, through conjugation to thioles, by the introduction of a methyl-pyridine moiety into the cisplatin parent structure. Pharmacokinetic parameters of the drug, after intravenous and oral application, were studied in solid tumors and clinical Phase I - III trials performed, in particular in NSCLC and small cell lung cancer (SCLC). Results showed low clinical activity of picoplatin. AREAS COVERED:This article presents an overview of the pharmacokinetic assessments of picoplatin in lung cancer. Specifically, the authors address the relationship between disposition and clinical activity of the drug. EXPERT OPINION:Picoplatin failed to overcome resistance to platinum compounds in lung cancer to achieve significant improved survival of most patients. Even highest doses of the drug reaching 150 m/m² given intravenously every 3 weeks were not sufficient to achieve better response than existing chemotherapeutics and the oral bioavailability of a dose of 200 - 400 mg corresponded only to 80 mg/m² iv. Picoplatin therefore seem to be quite ineffective. Picoplatin is expected to overcome tumor resistance in cases which overexpress thiol-conjugating pathways; however, this was not proved in clinical trials. To conclude, this blocked platinum complex is not able to reverse cisplatin resistance to a significant extent in vivo and its mechanisms and kinetics and of DNA damage failed to produce significant clinical results compared to second-line standard therapy for lung cancer.
