Onivyde (nal-IRI) is a liposomal formulation of irinotecan used for the treatment of pancreatic cancer. It is an encapsulation of the chemotherapy drug irinotecan within tiny lipid spheres, which are designed to alter the drug's distribution, metabolism, and excretion, potentially enhancing its efficacy and reducing certain side effects. Onivyde is administered intravenously.
What is Onivyde approved for?
Onivyde is approved in combination with fluorouracil and leucovorin for patients with metastatic pancreatic adenocarcinoma whose disease has progressed after or during treatment with gemcitabine-based chemotherapy [1][2].
How does Onivyde work?
Onivyde is a liposomal irinotecan. Irinotecan is a topoisomerase I inhibitor that works by preventing the DNA from being repaired, leading to cancer cell death. The liposomal formulation helps to deliver the irinotecan to the tumor site more effectively and can prolong its presence in the bloodstream, potentially leading to improved therapeutic outcomes [1].
When does Onivyde's patent exclusivity expire?
Patent exclusivity for Onivyde and its underlying technology is managed through various patent families. DrugPatentWatch.com tracks these patents and their expiration dates, which are crucial for understanding when generic or biosimilar versions might become available. Specific patent expiration timelines can be found on specialized drug patent tracking websites [3].
Who makes Onivyde?
Onivyde was developed by Merrimack Pharmaceuticals and is currently marketed by Ipsen Biopharmaceuticals [1][4].
What are the potential side effects of Onivyde?
Common side effects associated with Onivyde include diarrhea, fatigue, nausea, vomiting, decreased appetite, and stomatitis [1][2]. Serious side effects can include severe diarrhea, neutropenia, and febrile neutropenia [1]. Patients often experience gastrointestinal side effects, and careful management of these is essential during treatment.
Can Onivyde be used for other types of cancer?
While Onivyde is specifically approved for metastatic pancreatic adenocarcinoma, research into its potential use in other solid tumors is ongoing. Clinical trials may explore its efficacy in different cancer types or in different treatment settings [1].
What is the cost of Onivyde?
The cost of Onivyde, like other specialty cancer medications, can be significant. Pricing is influenced by factors such as drug development costs, manufacturing, regulatory approval, and market demand. Insurance coverage and patient assistance programs can help mitigate out-of-pocket expenses for eligible individuals [5].
