Eligibility Criteria

Inclusion Criteria

• Written informed consent must be obtained before any assessment is performed.
• Males and females aged 18 to 80 years included, with CKD-5D (GFR < 15 mL/min per 1.73m2) on stable hemodialysis as evidenced by monthly Kt/Vurea ≥ 1.20 (obtained from local laboratory) or urea reduction ratio ≥ 60% (obtained from local laboratory) for past 3 consecutive months prior to screening.
• Patient must be on maintenance renal replacement therapy (i.e., exclusively on standard hemodialysis with non-porous membrane) 3 times per week, for > 3 months before screening with a stable dialysis prescription, as defined by no change in material (i.e., dialyzer, filter/ membrane) type and dialysis duration for ≥ 4 weeks before screening.
• If patient is currently being treated with calcimimetics, the prescribed dose must be constant for at least 30 days prior to screening and should remain constant during the study duration.
• If patient is currently being treated with vitamin D, the prescribed dose must be constant for at least 30 days prior to screening and should remain constant during the study duration.
• Screening body mass index (BMI) between >18.5 and ≤ 35 kg/m2 and weigh of at least 50 kg.
• Able to communicate well with the investigator, to understand and comply with the requirements of the study.

Exclusion Criteria

• Patients who are on peritoneal dialysis.
• Patients who had a parathyroidectomy within 3 months prior to screening or patients who have a parathyroidectomy scheduled during the course of the study.
• Patients who have a kidney transplant scheduled during the study.
• Patients with clinically symptomatic spinal stenosis.
• Women who are pregnant or nursing (lactating).
• Women of child-bearing potential who are planning a pregnancy during the course and duration of the study.
• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during the study and for 5 half-lives (i.e., around 10 weeks) after stopping treatment. Highly effective contraception is defined as either:

1. Total abstinence: When this is in line with the preferred and usual lifestyle of the patient. [Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception].

2. Sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.

3. Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). [For female study patients, the vasectomised male partner should be the sole partner for that patient].

4. Use of a combination of any two of the following (1+2 or 1+3 or 2+3):

1. Use of oral, injected or implanted hormonal methods of contraception.

2. Placement of an intrauterine device (IUD) or intrauterine system (IUS).

3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.

In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.

• Liver disease or liver injury as indicated by abnormal liver function tests such as SGOT (AST), SGPT (ALT), γ-GT.
• Hemoglobin of ≤ 9 g/dL in male, and ≤ 8 g/dL in female patients. (Note: Treatment with erythropoietin-stimulating agents (ESA) is allowed).

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 80 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
