Study to Evaluate the Safety, Tolerability, PK and PD of DISC-0974 in Healthy Subjects

Enrolled participants in this study will receive a single dose of DISC-0974 or a placebo. Samples will be collected to measure how DISC-0974 is processed by the body and how the body responds when exposed to DISC-0974. Participants will receive a single study drug dose on Day 1; and follow-up for 10 weeks (71 days). If an undetectable DISC-0974 blood concentration is observed, the duration of follow-up will be shortened to 7 days thereafter, as feasible.
