A recently granted patent (Publication Number: US11969424B2) outlines a method for enhancing exercise capacity in individuals suffering from Pulmonary Hypertension Heart Failure with preserved Ejection Fraction (PH-HFpEF). The method involves administering levosimendan, its metabolites OR-1896 or OR-1855, or a combination thereof intravenously, orally, or subcutaneously to achieve a minimum 5-meter increase in the six-minute walk distance. The administration can be via IV infusion, oral dosing, or subcutaneous formulation, either as a standalone treatment or in combination with cardiovascular drugs like PDE inhibitors, nitrates, or calcium channel blockers.

Furthermore, the patent details specific dosages, administration methods, and monitoring protocols to ensure the safety and efficacy of the treatment. For instance, the method specifies steady-state blood levels of OR1896 between 0.20 ng/mL to 25.00 ng/mL, with oral dosages ranging from 1-4 mg per day. Importantly, the method aims to improve not only exercise capacity but also the quality of life in patients, as assessed by patient-reported outcome tools like Likert scales. Additionally, the method emphasizes the importance of monitoring for adverse events, such as arrhythmias, and ensuring that the treatment does not result in more serious adverse events compared to a placebo, thus highlighting the safety profile of the proposed intervention.
