title: Tolerability of recombinant-methionyl human neurotrophin-3 (r-metHuNT3) in healthy subjects.
abstract: This phase I, double-blind, randomized, placebo-controlled study evaluated the safety of single and multiple (daily for 7 days) subcutaneous administrations of recombinant-methionyl human neurotrophin-3 (r-metHuNT3) in healthy human volunteers at seven doses, ranging from 3 to 500 microg/kg/day. No serious or life-threatening adverse events occurred. The most frequently recorded adverse effects were mild injection-site pain, diarrhea, and elevation of liver function tests. No change in neurologic function was noted with these dosing regimens. We conclude that r-metHuNT3 is safe and well tolerated in the dosages used in this study.
