Summary

AV-1 is a human monoclonal antibody (mAb) being investigated as a potential therapy for dengue, a mosquito-borne viral disease with extensive global public health impact. Globally, over 2 billion people are thought to be at risk of infection from the dengue virus and there are an estimated 390 million infections each year. Current treatment options for dengue are limited to supportive care, so a safe and effective treatment would provide substantial public health benefits. AV-1 has not previously been tested in humans. This study aims to determine the safety of AV-1 in healthy adult volunteers, when administered as a single IV infusion.

b'Subject must be in good health at Screening (reaffirmed at Check-in):'

b'condition cannot: (i) Be first diagnosed within 3 months of enrollment; or (ii)'
b'Have worsened in terms of clinical outcome in the first 3 months; or (iii)'

b'participate in the study.'

b'Surgically sterile women - those who have had a hysterectomy, bilateral'
b'ovariectomy (oophorectomy), or bilateral tubal ligation, must provide'
