Study Summary

This is an open, standard therapy controlled clinical trial using a single intravenous infusion of HAM8101 (Adrecizumab) in patients hospitalized for AHF. This study will serve as a safety trial for HAM8101 (Adrecizumab) in AHF, using a dose escalating design.

Acute Heart Failure (AHF), both as deterioration of chronic stable condition or "de novo" onset constitutes a major indication of particular interest and continues to be a major health problem, with millions of people being affected, still associated with high mortality and rehospitalization rates despite numerous attempts to improve the situation.

It is believed that deteriorated vascular integrity and function, which manifests in various symptoms resulting from extravasation of fluid and solutes, is a key mechanism contributing to development and progression of the disease.

Therefore, it is warranted to start a phase 2 safety and proof of concept study with a new investigational product (IMP) that enhances the plasma concentration of bio-ADM in the circulation to restore and stabilize the vascular integrity and function in patients with AHF after initial stabilization with the current standard of care (SoC).

Study Description

The objectives of this study are to determine the safety/tolerability together with PD parameters of an intravenous slow infusion of 3 increasing doses of HAM8101 (Adrecizumab) in patients with AHF in a Phase IIa safety clinical trial. Efficacy of HAM8101 (Adrecizumab) will be explored secondarily.

The primary objective of this trial is to evaluate safety and tolerability of increasing doses of HAM8101 (Adrecizumab) in patients with AHF. Treatment emergent SAEs will be collected and carefully monitored on a continuous basis during the in-hospital stay and the 3-month follow-up after discharge. Treatment emergent AEs will be collected and monitored on a continuous basis during the in-hospital stay. Plasma and urine specimens will be collected daily from the first day of treatment until hospital discharge for routine safety assessments and to evaluate renal function.

All subjects will receive phone calls 30 (±7) days from start of study drug infusion to assess the occurrence of adverse events and serious adverse events, mortality and hospital readmission for HF or renal dysfunction. Patients will be contacted again 60 (±14) days and 90 (±14) days after infusion of HAM8101 (Adrecizumab) to document survival and episodes of re-hospitalization.

The study is designed primarily to understand the safety and tolerability of increasing doses of HAM8101 (Adrecizumab) in AHF patients (NYHA class II-IV) already in treatment and hemodynamically stabilized with a therapy that represents the standard of care (SoC) as recommended by international ESC 2016 Guidelines and it comprises 3 different patient "cohorts" with each cohort receiving one of 3 escalating doses of HAM8101 (Adrecizumab).

In addition, the study will provide a PD profile of HAM8101 (Adrecizumab) in AHF, in this acute condition.

After signing an Institutional Review Board approved Informed Consent Form, subjects will be asked to undergo screening procedures for study eligibility. Patients will be prescreened by site staff based on potential entry criteria as soon as possible after admission. Upon confirmation of eligibility and informed consent signature, the patient will receive the study drug within 48h from hospital admission. All patients will be evaluated daily during the hospitalization. In-hospital assessments of symptoms and signs of residual congestion (as composite congestion score) will be made daily from start of study drug infusion and up to Day 7, unless a patient is discharged earlier or later or dies earlier than Day 7. After discharge patients will be followed up for an additional 3 months for safety assessments with telephone contacts at months 1, 2, and 3, to document survival and episodes of re-hospitalization.

Thirty (30) patients with AHF (NYHA class II-IV) will be enrolled into 3 sequential experimental cohorts during the inpatient setting: 0.5 mg/kg, 2 mg/kg and 8 mg/kg of HAM8101 (Adrecizumab).

A control group of 10 patients with AHF will receive only standard of care treatment and will be monitored during the inpatient and outpatient settings.
