Northera Ongoing Trial May Satisfy FDA Request For More Efficacy Data, Chelsea Says

In a “complete response” letter to Chelsea for use of droxidopa in treating neurogenic orthostatic hypotension, FDA requests data from an additional trial showing efficacy and durability of effect. Chelsea believes ongoing Study 306, which has had its own efficacy challenges, could fill the bill and enable an NDA resubmission as early as the first quarter of 2013.
