Study Overview
Brief Summary
The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics and efficacy of APG-5918 in Healthy Subjects or Anemic Patients.
Detailed Description
The trial is composed of ttwo parts. Part A is a randomized, double-blind, placebo- controlled, single-dose escalation study in up to 7 cohorts to evaluate the safety, tolerability, and PK characteristics of APG-5918 in healthy volunteers and to explore whether MTDS will be achieved within the range of projected therapeutic doses for anemia.
Part B is an open-label,, multi-dose escalation trial in up to 6 cohorts to evaluate the safety, tolerability, PK and preliminary efficacy of APG-5918 in patients with anemia.

Outcomes
Primary Outcomes
Treatment-Emergent Adverse Events (TEAEs)
Time Frame: up to 7 days in Part A and 84 days or till EOT in Part B
TEAEs will be assessed via CTCAE version 5.0 based on the frequency of adverse events/serious adverse events (AEs/SAEs), clinically significant laboratory test results, 12-lead ECGs, and vital signs.
Secondary Outcomes
- Plasma Concentrations of APG-5918(Days 1, 2 and 3 in Part A; Days 1, 15 and 28 in Part B)
- Plasma Concentrations of APG-5918(Days 1, 2 and 3 in Part A; Days 1, 15 and 28 in Part B)
- Measurement of Hemoglobin(84 days or till EOT in Part B)
