ListOutcomeTime frameDescription
PrimaryNumber of Patients With Adverse Events, Serious Adverse and Death During Part 1 of the StudyPrior to delivery until 4-6 weeks post partum (maximum of 8 weeks)Safety and tolerability was assessed by adverse events/serious adverse event and death monitoring.
PrimaryChange From Baseline in Maternal Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) in Part 1of the Study (Part 1)From baseline to during treatment period of a maximum 72 hours infusion prior to delivery until 4-6 weeks post partum in part 1 (maximum of 8 weeks)Maternal safety assessment to monitor pre-eclampsia by checking blood pressure during 72 hour treatment period as well as post-dose.
PrimaryChange From Baseline in Mean Maternal Arterial Pressure (Part 1)From baseline to during treatment period of a maximum 72 hours infusion prior to delivery until 4-6 weeks post partum in part 1 (maximum of 8 weeks)Maternal safety assessment to monitor pre-eclampsia by checking mean arterial pressure during 72 hour treatment period as well as post-dose.
PrimaryChange From Baseline on Maternal Proteinuria (Part 1)From baseline to during treatment period of a maximum 72 hours infusion prior to delivery until 4-6 weeks post partum in part 1 (maximum of 8 weeks)Pre-eclampsia was monitored by checking levels of protein in urine and by urinary protein/creatinine ratio (UPCR)
PrimaryDecrease in Utero-placental Blood Flow (Part 1)During treatment period of a maximum 72 hours infusion prior to delivery and up to delivery in part 1 (maximum of 3 weeks)Blood flow to the fetus was monitored using via a Doppler.
PrimaryChange in Fetal Heart Rate (Part 1)During treatment period of a maximum 72 hours infusion prior to delivery and up to delivery in part 1 (maximum of 3 weeks)Heart rate of fetus was monitored continuously throughout 72 hour treatment period using a cardiotocograph.
PrimaryImprovement in Renal Function Assessed by Increase in Creatinine ClearanceFrom randomization until 4-6 weeks post partum (maximum 8 weeks)
PrimaryRate of Spontaneous Delivery and/or Mode of DeliveryFrom randomization to delivery (maximum of 3 weeks)
PrimaryNumber of Patients With Absence of Anti-serelaxin AntibodiesFrom Randomization until 4-6 weeks post partum (maximum of 8 weeks)
Primary

up to 4 - 6 weeks post partum (maximum of 8 weeks )
PrimaryNumber of Patients With Abnormalities in Fetal Cardiotocography and Biophysical ProfileRandomization to delivery (maximum of 3 weeks)
PrimaryPharmacokinetics of RLX030: Area Under the Blood Concentration-time Curve From Time Zero to Infinity (AUCinf)-Part 1Baseline, 2, 6, 24,48,72, 76, 80 and 90 hours after initiation of infusion during part 1Blood concentrations of RLX-030 was assayed to determine this PK parameter.
PrimaryPharmacokinetics of RLX030: Area Under the Blood Concentration-time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUClast)-Part 1Baseline, 2, 6, 24,48,72, 76, 80 and 90 hours after initiation of infusion during part 1Blood concentrations of RLX-030 was assayed to determine this PK parameter.
