The decision is based on safety findings only, no efficacy data will be considered. After the DSMB has reached a decision on the dose to be continued, all subjects randomized to receive PQ912 will be reallocated to this dose (1:1). The duration of Subjects participation in the study is either 48, 60, 72, 84 or 96 weeks of treatment (depending on time of randomization).
