12. IPD Sharing Statement

Plan to Share IPD
Undecided
IPD Sharing Plan Description
This is a proof-of-concept study assessing the safety, tolerability, PK, and efficacy of systemic use of NGM621 versus placebo in both healthy subjects and subjects confirmed with SARS-CoV-2 infection. We will continue to evaluate whether IPD will be shared with other researchers.
