FDA Nixes Data Package on Cardiome NDA Proposed Resubmission

Share

FDA has told Cardiome Pharma that a data package proposed by the company would not be sufficient to support a resubmission of its NDA for Brinavess (vernakalant hydrochloride, IV), an antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation. “In our most recent communication with the FDA, we proposed resubmission of the NDA based upon the original file and six years of accumulated safety data from sales of Brinavess in thirty-three countries, augmented by interim results from over 1,100 patients enrolled in the SPECTRUM study, a prospective post-authorization European Union safety study, along with pre-clinical data from subsequent studies the company completed at the FDA’s request,” Cardiome says. “We are disappointed that the agency did not find these data compelling enough to recommend a resubmission, especially when several regulatory bodies in major jurisdictions around the world, including Canada in 3/2017, have found the drug to be safe and effective.”

 

In 2008, FDA issued Cardiome an “approvable” letter for the drug, asking for “additional information associated with the risk of previously identified events experienced by a subset of patients during the clinical trials in order to assure an acceptable risk benefit profile compared to electrical cardioversion,” according to the company. It had also asked for a safety update from all ongoing or completed studies of vernakalant, regardless of the indication.
