Overview

Randomized. double blind, placebo controlled, parallel arms dose finding study with a 4 weeks treatment period

The study consists of a screening period of approximately 1 week, a wash out period of up to 3 weeks, where existing phosphate lowering medication is withheld, a 4-week treatment period and a follow-up period of up to 2 weeks, during which patients are put back on their pre washout phosphate lowering medication. The wash out period will be either 1 week, 2 weeks or 3 weeks depending on the increase in s-phosphate levels. There are 7 parallel treatment arms in the study with bid and od treatment regimens. Laboratory efficacy endpoints and safety assessments will be evaluated at various times throughout the study.
