Brief Summary

The CANNON trial is a prospective, open-label, randomized, multicenter study designed to investigate rational hemoglobin target value in patients with anemia of non-dialysis chronic kidney disease treated with enarodustat. Eligible patients are randomly assigned 1:1 to the high-hemoglobin target group （hemoglobin of 13 g/dl）and low-hemoglobin target group （hemoglobin of 11 g/dl）and administered with enarodustat to achieve and maintain target hemoglobin over 96 weeks. The first primary endpoint was the difference of mean change in 36-Item Short Form Health Survey at week 24. The second primary endpoint was safety endpoints included time to major adverse cardiovascular + event (MACE+; all-cause mortality, myocardial infarction, stroke, and congestive heart failure requiring hospitalization) during 96 weeks.

Detailed Description

This study is a prospective, open-label, randomized controlled, multicenter investigation conducted among adult patients with ND-CKD anemia in China, with the aim of exploring the rational hemoglobin target value for the treatment of patients with ND-CKD anemia using enarodustat.

This study plans to enrol 1,670 patients with non-dialysis chronic kidney disease (ND-CKD) anemia. After screening, patients who meet the inclusion criteria and do not meet the exclusion criteria will be randomly assigned at a 1:1 ratio to: the low Hb target value group: with a Hb target value of 11 g/dL; the high Hb target value group: with a Hb target value of 13 g/dL. The initial dose of enarodustat tablets in both groups is 4 mg once daily. The dose will be adjusted in accordance with the instructions and the requirements of different Hb value groups.

The follow-up period will last for 96 weeks. The first primary endpoint was the difference of mean change in 36-Item Short Form Health Survey at week 24. The second primary endpoint was safety endpoints included time to major adverse cardiovascular + event (MACE+; all-cause mortality, myocardial infarction, stroke, and congestive heart failure requiring hospitalization) during 96 weeks.
