Brief summary
A multicenter, randomized, controlled study in Sweden (n=110). This study consists of 2 phases: 1) open-label run-in within approximately 2 months, and 2) randomized, double-blinded and placebo-controlled treatment for 6 months. The open-label phase, in turn, consists of three periods: up-titration (normally 1 - 2 weeks, and longer in some cases), correction (maximum 72 hours) and maintenance (4 - 7 weeks).
