Albireo today announced the completion of a phase 1b study showing a favorable tolerability and safety profile of A3309 in patients with chronic idiopathic constipation. In addition, the data revealed appropriate efficacy signals in this patient population. A3309 is a first in class compound developed for the treatment of chronic idiopathic constipation and constipation-predominant Irritable Bowel Syndrome (IBS-C). Based on these results, Albireo expects to recruit 180 patients with chronic idiopathic constipation in a US phase 2b study (www.clinicaltrials.gov) under an IND recently placed into effect by the FDA.
