Evaluation of Systemic Exposure of CP: Baseline-corrected CP Serum Concentrations (µM) by Nominal Timepoint
This will be evaluated by collecting blood on Day 1 baseline, Day 14 at 30 minutes pre-dose, and 5, 20, 35, and 50 minutes post-dose only in OP0201 Cohort B 60 mg per day
Time frame: Day 1 and Day 14
Population: It is pre-specified to collect and report data for only Cohort B and Placebo Arms/Groups per protocol. The Number of participants analyzed for Cohort B at Day 14, 30 mins pre-dose and 5 mins post-dose is one less compared to other timepoints due to exclusion of serum samples that had missing collection times.
