Primary Endpoints
Modified Neuropathy Impairment Score +7 (mNIS+7)
18mo

The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in mNIS+7 at 18 months. The mNIS+7 is a composite score that quantitates motor, sensory, and autonomic neurologic impairment due to injury of large and small nerves. The minimum and maximum values are 0 and 304, respectively. A higher score indicates a worse outcome.
