Phase IV Study of Chronic Infusional Epoprostenol for Severe Primary Pulmonary Hypertension

2014-08-27 03:58:12 | BioPortfolio

Summary

OBJECTIVES: I. Provide epoprostenol (Flolan, prostaglandin I2) by chronic infusion to patients with severe primary pulmonary hypertension for whom no alternative therapy is available.

II. Obtain additional safety information on continuous infusion epoprostenol. III. Obtain additional information on economic resource health consumption.

Description

PROTOCOL OUTLINE: Patients are treated with a chronic continuous infusion of epoprostenol.

The highest tolerated infusion rate is determined for each patient by gradually increasing the rate until the target dose is reached or the patient experiences at least 1 dose-limiting effect.

Patients are subsequently treated with a chronic continuous infusion, beginning at a rate below the highest tolerated rate. Attempts are made to increase the dose to the highest tolerated rate over the first 72 hours.

Medical and Biotech [MESH] Definitions

A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).

Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.

Familial or idiopathic hypertension in the PULMONARY CIRCULATION which is not secondary to other disease.

Cell surface receptors for EPOPROSTENOL. They are coupled to HETEROTRIMERIC G-PROTEINS.

A multisystemic disorder characterized by a sensorimotor polyneuropathy (POLYNEUROPATHIES), organomegaly, endocrinopathy, monoclonal gammopathy, and pigmentary skin changes. Other clinical features which may be present include EDEMA; CACHEXIA; microangiopathic glomerulopathy; pulmonary hypertension (HYPERTENSION, PULMONARY); cutaneous necrosis; THROMBOCYTOSIS; and POLYCYTHEMIA. This disorder is frequently associated with osteosclerotic myeloma. (From Adams et al., Principles of Neurology, 6th ed, p1335; Rev Med Interne 1997;18(7):553-62)
