Declarations
:
: K. Ikejiri, S. Muto, H. Takama, K. Yamawaki, T. Miyazawa and I. Urakawa are employees of Kyowa Kirin. M. Nangaku has received research grants, consulting fees, and lecture fees from Kyowa Kirin and is vice president of the Japanese Society of Internal Medicine, president of the Asian Pacific Society of Nephrology, and president-elect of the International Society of Nephrology. T. Akizawa has received consulting fee and honoraria from Kyowa Kirin. T. Suzuki, Y. Aoki, A. Otsuki, F. Katsuoka, K. Kinoshita and M. Yamamoto declare no conflicts of interest.
: Approval for the study protocol and its amendments were obtained from the institutional review board at each study site and all work was carried out in accordance with the Declaration of Helsinki. The informed consent form (ICF) for the storage and use of blood samples for genome analysis was separate from the ICF for the TSUBAKI study participation. Whole blood samples for genome analysis were collected at baseline only from patients who provided written informed consent for both study participation and genome analysis. The genotyping substudy plan was established at the time of SNP analysis and approved by the ethics committee of Kyowa Kirin Co., Ltd. and ToMMo. Patients were also given the opportunity to exclude themselves from the substudy via an opt-out approach at study initiation.
