SEOUL, South Korea, June 13, 2011 /PRNewswire/ -- Dong-A PharmTech Co., Ltd. and Dr. Falk Pharma GmbH announced positive results from an initial safety and efficacy portal hypertension study in man using udenafil, its new long-active phosphodiesterase inhibitor. The data was presented by the principal investigator, Prof. Wolfgang Kreisel, Department of Gastroenterology, Hepatology, Endocrinology and Infectious Diseases, University of Freiburg, Freiburg, Germany.
In a 1-week open-label, multicenter phase 2 trial, 20 patients with portal hypertension (Child-Pugh A/B) that met the selection criteria were given a daily oral dose of one of four dose levels of udenafil. The primary efficacy endpoint was the change of hepatic venous pressure gradient (HVPG) from day 0 (pre dose) to day 6 post dose. A total of 7 of 20 patients showed a response defined as a HVPG reduction of < 12 mmHG or by > 20% after one week of daily dosing. In the high dose group, HVPG was lowered in 4 of the 5 patients by more than 10% after administration of study drug on day 0 or day 6. No decrease of mean arterial blood pressure was seen in any of the four dose groups. Standard liver biochemical tests did not change during the study and no adverse events were attributed to the study drug.
The results of this study show that the oral application of the new PDE-5 inhibitor udenafil lowers HVPG in an acute setting without any systemic cardiovascular side effects. Effectiveness appears to be dose related. Further study is contemplated using a placebo controlled design and a longer study duration.
