Clinical Trial Summary

JTZ-951 is a currently being developed as a treatment for renal anemia. This study aims to evaluate the efficacy and safety of JTZ-951 following a switch from erythropoiesis-stimulating agent (ESA) in Korean subjects receiving HemoDialysis with renal anemia.

This study is a Phase III, open, active-controlled, parallel-group, multi-center study.

The total duration of the study will be 30 weeks including screening, treatment and follow-up.

Description:

The primary objective is to demonstrate non-inferiority of JTZ-951 to darbepoetin alfa.

3. Patients with congestive heart failure (NYHA Class III or more) or unstable angina

4. Patients who have developed myocardial infarction, cerebral infarction (excluding asymptomatic cerebral infarction), or venous thromboembolism (pulmonary embolism or deep vein thrombosis) during the period between 24 weeks before Scr Visit 1 and Week 0.

5. Patients who will undergo an ophthalmological procedure (photocoagulation therapy or vitreous surgery) for the treatment of diabetic retinopathy, diabetic macular edema, or age- related macular degeneration during the period between Scr Visit 1 and the end of the study

6. Patients who have undergone erythrocyte transfusion during the period between 12 weeks before Scr Visit 1 and Week 0.

15. Patients who have previously participated in a clinical study of JTZ-951 and received the investigational product

16. Patients who are pregnant, lactating, or may be pregnant (the possibility of pregnancy cannot be ruled out by the PI or the SI based on the results of pregnancy test at Scr Visit 1)

17. Female patients of childbearing potential who have not agreed to use appropriate contraception methods (medically accepted contraceptive methods: surgical sterilization, intrauterine device, condom, diaphragm, etc.) from the time of signing of informed consent to the end of the study, or male patients who have not agreed to use appropriate contraception methods from the start of study treatment to the end of the study.
