Healthy Participants study: SR604
Official title A Study of Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of SR604 in Two Participants Groups (Part A: Healthy Participants, and Part B: Participants With Hemophilia A or Hemophilia B or Factor VII Deficiency)
ClinicalTrials.gov ID: NCT06349473
What this study is testing
What is SR604?
SR604 is an investigational subcutaneous injectable medicine being studied for safety, tolerability, pharmacokinetics, pharmacodynamics, and potential efficacy in healthy participants and people with Hemophilia A, Hemophilia B, or Factor VII deficiency.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether SR604 is safe and how it behaves in the body in healthy people and in people with hemophilia or factor VII deficiency.
- Who it's for
- You may be able to join if you are a healthy adult or you have hemophilia A, hemophilia B, or factor VII deficiency.
- What's involved
- You would receive SR604, a study drug, and have blood tests to check safety and how the drug moves in your body. You may have several clinic visits for these checks.
- Time commitment
- The study lasts a few weeks with multiple visits, including an initial visit and follow‑up visits.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.
