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.

  • 5. Ability to understand and voluntarily sign a written informed consent form, which must be signed before any trial-specific procedures are performed.

Exclusion Criteria

  • 1. Healthy Subjects:
  • History of any disease or clinical condition that, in the investigator's opinion, may confound the study results or pose additional risk to the subject with administration of the study drug.
  • ALT or AST > 2×ULN, or TBIL > 1.5×ULN at screening.
  • Undergone surgery (excluding minor cosmetic or dental procedures) within 3 months prior to screening.
  • Blood donation or blood loss exceeding 400 mL within 3 months prior to screening, or planned donation of blood or blood components during the study period.
  • Use of another investigational product within 30 days or 5 half-lives (whichever is longer) prior to dosing, or current participation in a prospective study of an investigational product or medical device.

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)
