This is a Phase 2 randomized, placebo-controlled, double-blind study that will be conducted in 2 parts: sequential dose escalation in Part A, followed by dose expansion in Part B.~In Part A, approximately 40 evaluable subjects will be assigned 1:1:2 overall to Cohort 1, Cohort 2 or placebo. Doses of scp776 will be tested sequentially in 2 cohorts, each in parallel with a volume-matched placebo randomized as 1:1 scp776:placebo within each cohort, to maintain the overall 1:1:2 ratio. Subjects will receive doses of either normal saline (placebo) or scp776, approximately 24 hours apart.
