Ironwood Pharma to co-promote Viberzi (eluxadoline) in the US with Allergan for irritable bowel syndrome
Ironwood Pharmaceuticals announced an agreement with Allergan plc for the US co-promotion of Viberzi (eluxadoline), Allergan’s new treatment for adults suffering from irritable bowel syndrome with diarrhoea (IBS-D). This arrangement is separate from and complementary to the companies’ ongoing co-development and co-commercialisation of linaclotide (Linzess, or Constella in the EU) for the treatment of adults with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC).
Comment; Viberzi was US approved in May 2015. Ironwood has a specialty sales force of about 25,000 reps who will now co-promote Viberzi alongside Allergan – Linzess will remain the lead product.
