Enarodustat Tablets at Different Initial Doses for Anemia in Non-dialysis CKD Patients

Официальное название

A Prospective, Single-arm, Open-label Study to Evaluate Different Initial Doses of Enarodustat Tablets for the Treatment of Anemia in Patients With Non-dialysis Chronic Kidney Disease

Обзор

To evaluate the rationality of different initial doses of enarodustat for the treatment of anemia in ND-CKD patients

Подробное описание

The eligible subjects screened will be stratified by treatment history and randomized to the 2, 3, 4 mg dose groups in a 1:1:1 ratio. After receiving the initial doses of 2, 3, 4 mg/day for 4 weeks, the subjects will enter a 12-week maintenance treatment period with a total of 7 scheduled visits.

• Препарат Enarodustat 2mg
  initial phase：2mg QD for 4 weeks subsequent phase：1mg、2mg、4mg、6mg、8mg QD，adjust the dose based on hemoglobin concentration level every 4 weeks
• Препарат Enarodustat 3mg
  initial phase：3mg QD for 4 weeks subsequent phase：1mg、2mg、4mg、6mg、8mg QD，adjust the dose based on hemoglobin concentration level every 4 weeks
• Препарат Enarodustat 4mg
  initial phase：4mg QD for 4 weeks subsequent phase：1mg、2mg、4mg、6mg、8mg QD，adjust the dose based on hemoglobin concentration level every 4 weeks

• Patients with congestive cardiac failure (New York Heart Association \[NYHA\] Class III or above) or unstable angina;
• Patients who have experienced myocardial infarction, transient ischemic attack, cerebral infarction (except asymptomatic cerebral infarction) or venous thromboembolism (pulmonary embolism or deep vein thrombosis) from 24 weeks before screening to the first dose of the investigational drug;
• Patients with severe hepatobiliary disorders (e.g., AST or ALT >2.5 × upper limit of normal (ULN) at the screening visit, patients with hepatic cirrhosis or total bilirubin ≥1.5 × ULN at the screening visit);
• Patients who have received red blood cell transfusion from 12 weeks before screening to the first dose of the investigational drug;
