The US Food and Drug Administration (FDA) has accepted for review AMAG Pharmaceuticals' supplemental new drug application (sNDA) for Feraheme (ferumoxytol) injection for Intravenous (IV) use.
The sNDA filed is to expand the indication for ferumoxytol for the treatment of iron deficiency anemia (IDA) in adult patients with chronic kidney disease (CKD), who have failed or could not take oral iron treatment.
Ferumoxytol is currently indicated for oral use for the treatment of IDA in adult patients with CKD, according to the company.
The sNDA included the data from a global phase III program, which included two phase III clinical trials such as as IDA-301 (placebo comparator) and IDA-302 (active comparator).
The trials, which enrolled 1,400 patients, evaluated the use of ferumoxytol in a broad range of adult IDA patients, all of whom had failed or could not take oral iron treatment.
Both studies achieved the primary efficacy endpoints with statistically significant improvements in hemoglobin from baseline to the 35-day.
The studies, which also included patient-reported outcomes data as pre-specified secondary and exploratory endpoints, found no new safety signals, outside of those described in the current Feraheme (ferumoxytol) label, were observed with ferumoxytol treatment in these studies, claims the company.
In response to the application, the FDA said it will complete the review of Feraheme sNDA by 21 October 2013.
