Details and patient eligibility

About

The study will compare the pharmacokinetics (PK), safety and tolerability of long-term infusion of lyophilized landiolol (LDLL600) against esmolol (Brevibloc) by measurement of blood concentrations of landiolol, esmolol and their metabolites, and by monitoring systemic cardiovascular and local tolerability, blood pressure (BP), ECG including heart rate (HR) and adverse events (AEs).

Full description

12 subjects will be administered LDLL600 and Brevibloc in a double-blind, randomized, cross-over setting. PK, systemic cardiovascular and local tolerability and safety of 24-hour long infusions of three dose levels of both Investigational Medicinal Products (IMPs) during each treatment period will be assessed.

Each treatment period will consist of:

Dose level 1 (LOW) for 2 hours (h) Dose level 2 (MEDIUM)for 2 hours Dose level 3 (HIGH)for 2 hours PK and tolerability observation at dose level 3, 2 or 1 will be continued for 18 hours in order to end up with a total infusion period of 24 h Post-infusion follow-up (FU)for 6 hours after infusion termination

The duration of the wash-out period between treatment periods will be at least two days. Each subject, if confirmed eligible, will complete two treatment periods in total.

In case of poor tolerability, alternative dosing schemes will be followed.
