ALP-1 Continuous Intravenous Infusion to Maintain Clinical Stability in Advanced Heart Failure

This is a global multicenter, doubleblind, placebo-controlled, randomized, parallel-group study that compares ALP-1 given in a continuous infusion ( compared to placebo), 250mcg/day on majore outcomes up to 6 months after randomization in participants with advanced HF with reduced ejection fraction(HFrEF).

We anticipate needing to screen ca. 600 patients in order to ransomize our target sample size of 400 participants. Participants will be randomozed 1:1to receive either alprostadil or placebo. Based on prior data, we expect the 6-month event rate to be 64% in the control group and 47% in the intervention group. The planned duration of following-up for each patient is 6 months on the randomized trial intervention and a final follow-up visit will be performed 30 days after stopping the trial intervention. Eligible patients will be randomzied via a centralized IXRS to eith alprstadil or placebo. The planned study dusration is approximately 3-4 years from first randomized patient to last patient. When a participant is deemed eligible to participate in the trial, a central line which will be used for infusion of double-blind treatment will be inserted, if not already in place. Continue infusion delivery system will be operated by a pump. Infusion of trial intervention will be initiated while the participant is in the hospital of infusion centre and the participant is to remain under observation for at least 8 hours for monitoring of vital signs and adverse event(AEs).
