Lantheus Application for Tumor Imaging Drug Rejected Due to Manufacturing Concerns

By Anvee Bhutani


Lantheus Holdings's new drug application was rejected by the Food and Drug Administration's due to unresolved manufacturing issues at a third-party facility.

The application was for LNTH-2501, an imaging drug designed to help detect neuroendocrine tumors, a type of cancer, the Bedford, Mass., company said Friday.

The FDA said in its complete response letter it couldn't approve the application because of issues at the facility that produces the drug, Lantheus said. Those issues must be resolved before the application can be approved.

Lantheus said the FDA didn't identify any concerns about the drug's safety, effectiveness or the clinical data submitted with the application.

LNTH-2501 is one of the company's late-stage oncology product candidates. The company said it is working with its manufacturing partner and the FDA to address the manufacturing issues and advance the application.
