Primary Outcome Measures:
  • Change from baseline in serum phosphate levels at the end of the treatment period [ Time Frame: Baseline to Week 8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of participants achieving the target PSPL (Pre-dialysis serum phosphate level) and time to achievement [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Serum calcium level corrected by serum albumin level at the end of the treatment period [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Serum calcium x phosphate product at the end of the treatment period [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Serum intact-PTH (Parathyroid) levels at the end of the treatment period [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Safety variables will be summarized using descriptive statistics based on adverse events collection [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
