Efficacy of nab-paclitaxel in treating metastatic melanoma.

INTRODUCTION: Systemic treatment of metastatic melanoma has been revolutionized by the advent of checkpoint inhibitors and targeted agents which are widely accepted as standard front-line therapies. However, despite these major advances, a substantial portion of patients still fail checkpoint inhibitors and/or targeted agents and are not candidates for clinical trials. Commonly used cytotoxics in these patients include paclitaxel, dacarbazine, platins, and temozolomide. The overall response rates of these agents are usually disappointing and short-lived. Areas covered: Herein, the author provides a literature review of the role of nab-paclitaxel in metastatic melanoma including coverage of its pharmacokinetics, pharmacodynamics and efficacy. Expert opinion: The role of chemotherapy in the treatment of metastatic melanoma is limited to patients who failed checkpoint inhibitors and, when applicable, targeted agents, and those not appropriate for clinical trials. nab-Paclitaxel has single agent activity in chemotherapy-naïve untreated metastatic melanoma which compares favorably to the activity of weekly paclitaxel or single agent dacarbazine. However, the activity in chemotherapy-pretreated patients is modest. Data on nab-paclitaxel in patients pretreated with targeted agents or check point inhibitors are lacking. Further advances are expected from new checkpoint inhibitors and targeted agents for the treatment of metastatic melanoma in addition to the optimal combination and sequencing of these agents.
