Brief summary: Approximately 9 participants will be enrolled in the study in a single cohort. Participants will be randomized to 3 g IXT-m200 or placebo at 7:2. Each will receive their dose as a 30-min intravenous infusion, then remain at the study site overnight to complete Day 1 and Day 2 assessments (e.g., electrocardiogram (ECG), laboratory assessments, blood draws, and vital signs). Following discharge on Day 2, participants will return to the clinic for follow-up pharmacokinetic (PK) and safety assessments on Day 8, then every 1-3 weeks thereafter until Day 127.
