6. CKD Stage 4 as determined by eGFR between 15-29 mL/min/1.73 m2 using the CKD-EPI equation.

Exclusion Criteria:

1. History of malignancy except carcinoma in situ in the cervix, early stage prostate cancer or non-melanoma skin cancers.
2. Use of investigational drugs or participation in another clinical trial within 30 days or 5 half-lives prior to screening, whichever is longer.
