This is a two-part study is to evaluate the multi-day safety, tolerability, and pharmacokinetics (PK) of orally administered GS-441524 in a healthy human volunteer.
Women recruited from the internet will be put in a hypothetical situation of being in labor at 22 weeks of pregnancy, and presented with information on the likelihood of survival and chance of disability for babies born at this gestational age. Participants will be randomized to receive this outcome data in one of three formats: as text-only, in a static pictograph, or in an iterative pictograph. Participants will also be randomized to seeing the chance of survival as 30% or 60%. Participants were then asked to choose between comfort care and intensive care in this situation. Participants' religiosity, value of the sanctity of life, and health literacy were also assessed.
