FDA wants more data on J&J and Alkermes' Risperdal Consta

16 February 2009

The Food and Drug Administration has asked the USA's Alkermes and partner Johnson & Johnson for additional information regarding their  supplemental New Drug Application for Risperdal Consta (risperidone).  The sNDA, submitted in April 2008, sought approval for the drug as  adjunctive maintenance treatment to delay the occurrence of mood  episodes in patients with bipolar disorder who relapsed frequently.

Risperdal Consta was initially approved in the USA in 2003.
