Beraprost modified release, in addition to treprostinil, is in clinical development for the oral treatment of pulmonary arterial hypertension (PAH), a rare condition causing high blood pressure in the lungs. PAH can worsen over time and cause several problems including heart failure and blood clots. In PAH, the arteries in the lungs become thickened and stiff meaning the arteries cannot stretch as well to allow blood to flow through. This makes it harder for the heart to bump blood through the arteries leading to high blood pressure and weakening of the heart.
Beraprost modified release works by mimicking a naturally available substance in the body called prostacyclin which relaxes and widens the blood vessels and prevents the formation of blood clots. It is expected that beraprost modified release will relax and widen the blood vessels in the lungs, lowering blood pressure and therefore improving symptoms of PAH. This formulation of beraprost releases the drug over several hours, which reduces the frequency of administration, making this treatment more convenient to take. If licensed, beraprost modified release will offer an additional treatment option for patients with PAH in addition to treprostinil targeted therapy.
Angiotensin II acetate is in clinical development for the treatment of catecholamine and/or vasopressin resistant hypotension due to distributive shock. Shock is a critical condition in which blood pressure drops so low that the brain, kidneys and other vital organs cannot receive enough blood flow to function properly. Distributive shock is the most common type of shock that is most commonly caused by bacterial or fungal infection (septic shock) or allergic reaction (anaphylactic shock). Severe shock is usually treated with drugs called catecholamines or vasopressin. Shock that does not respond to treatment with these drugs is resistant shock.
