About

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable disease characterized by persistent respiratory symptoms and incompletely reversible airflow limitation. It is usually caused by airway and / or alveolar abnormalities caused by obvious exposure to toxic particles or gases.COPD is currently the fourth leading cause of death in the world, and is expected to be the third leading cause of death by 2020.HPP737 as an oral PDE4 inhibitor for the treatment of COPD.Preclinical data showed that the activity of HPP737 was similar to that of rofloxacin, but HPP737 significantly reduced the permeability to CNS and may have better tolerance. HPP737 will be used to develop indications for chronic obstructive pulmonary disease, and PK study in Chinese people is going to to evaluate the safety and tolerability of HPP737 in healthy volunteers.

Full description

This PK study it to evaluate the safety and tolerability of HPP737 in healthy subjects.

84 healthy subjects were included.A single dose of about 48 patients: expected 6mg, 10mg, 20mg, 40mg or undetermined, 12 subjects in each group, the ratio of HPP737 to placebo was 3:1 (9 cases: 3 cases), 6mg and 10mg could be carried out simultaneously.The dose group and the total number of subjects can be adjusted according to the latest data obtained.

There were 36 patients with multiple doses: expected 10mg, 20mg, 40mg or undetermined, with 12 subjects in each group. The ratio of HPP737 to placebo was 3:1 (9 cases: 3 cases). The dose group and total number of subjects could be adjusted according to the latest data. Multiple dose group and single dose group can be carried out simultaneously. Each multiple dose group will be enrolled after the first subject in the same dose group of single dose is enrolled.
