irinotecan liposome injection

Posted on April 12th, 2016 by

Class: Chemotherapy

Generic Name: irinotecan liposome injection

Trade Name: Onivyde™

For which conditions is this drug approved? Onivyde in combination with fluorouracil and leucovorin is indicated for the treatment of patients with metastatic pancreatic cancer whose cancer has progressed after gemcitabine-based therapy.

What is the mechanism of action?  Onivyde is thought to work by blocking the action of an enzyme in cells called topoisomerase I. Cells need this enzyme to keep their DNA in the proper shape when they are dividing. Blocking this enzyme leads to breaks in the DNA, which leads to cell death. Because cancer cells divide faster than normal cells, they are more likely than normal cells to be affected by liposomal irinotecan. And because Onivyde is formulated as a nanoliposomal encapsulation of the drug irinotecan, it can stay in circulation in the body longer than standard irinotecan. This allows greater drug take-up within the tumor cells and converts it to its active form, SN38, which promotes cancer cell death.

How is Onivyde typically given (administered)? Onivyde is given as in infusion into a vein.
