Study information

Scientific title

A study of INT-747 (6-ethyl chenodeoxycholic acid [6-ECDCA]) in combination with ursodeoxycholic acid (UDCA [URSO®]) in patients with primary biliary cirrhosis (PBC)


Study hypothesis

The primary hypothesis is that INT-747 will cause a reduction in alkaline phosphatase (AP) levels in primary biliary cirrhosis (PBC) patients, over a 12 week treatment period, as compared to placebo.

Primary biliary cirrhosis


1. Experimental treatment: INT-747 10 mg orally po once daily (QD)
2. Experimental treatment: INT-747 25 mg po QD
3. Experimental treatment INT-747 50 mg po QD
4. Matched placebo comparator: placebo po QD

Screening can last up to 4 weeks. Treatment is 12 weeks. Follow up after treatment is 2 weeks. Ursodeoxycholic acid (UDCA) treatment is prescribed by each patient's physician; the UDCA dose and timing of its administration each day is determined by each patient's physician (not by the protocol).
