Moderato System in Patients With Hypertension

Protocol CS-03 Ver 1.1 (NCT02837445) was amended at the advice of the Scientific Advisory to protocol CS-03 Version 3.0 with more stringent hypertension inclusion criteria and different observation intervals for efficacy and safety. In CS-03 Version 3.0 the time of the primary efficacy endpoint was reduced from 6 months to 3 months post randomization which was deemed a suitable interval for the chronic effect, whereas for the safety endpoint, the period was lengthened to 12 months post randomization to better monitor potential risks of the treatment on cardiac function (Blinding period was increased from 6 months to 12 months). Protocols were thus split in order to allow better clarification to the difference in the time to the primary endpoints for efficacy and safety between the two CIP versions and simplify data analysis. Protocol Ver 3.0 prescribes data analysis of all patients randomized under version 1.1 to be performed once they complete the 6 months follow-up as set in protocol version 1.1 (NCT0283744). It is expected that \~40 patients will be randomized according to protocol version 1.1 prior to the enrollment of patients according to protocol version 3.0. The results will be considered as interim analysis. The recruitment for the protocol version 1.1 is now completed. Total of 47 patients were randomized according to protocol version 1.1 and all patients completed the follow-up period for the primary endpoint. Patients are currently being followed up for the study "extension period".
