Almirall, S.A. (ALM:MC) and Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) announced the launch of Constella® (linaclotide 290mcg capsules once daily), the first approved prescription therapy in a new class of treatments for adults suffering from moderate to severe IBS-C,(1) in Europe. Constella® is now available in Germany, the UK and Nordic countries and is expected to be launched in several other European countries in 2013.
Constella is the first and only product approved in the EU for the treatment of IBS-C in adults and has been demonstrated in clinical trials to improve abdominal pain – one of the hallmark symptoms of IBS-C, as well as to improve constipation-related symptoms. IBS is a functional, chronic and relapsing gastrointestinal disorder affecting over 10% of the European population, and it is estimated that one-third of IBS patients suffer from IBS-C (2) with different degrees of severity. Symptoms associated with IBS-C include abdominal pain and/or discomfort, bloating and constipation.
“The availability of linaclotide is excellent news for the one-third of adult IBS patients that have constipation. The symptoms associated with the condition can negatively impact the lives of patients. A targeted prescription treatment specifically for IBS-C is extremely welcome – for both appropriate patients and physicians alike who can now better manage this unpleasant, chronic condition”, said Professor Eamonn Quigley, Gastroenterologist.
The IBS-C Diagnosis
The diagnosis and management of IBS-C can be frustrating for both patients and clinicians alike (3). 30% of gastrointestinal problems reported in general practice consultations are IBS (4) but only 19% of patients are diagnosed during their first consultation (4) with 56% of patients requiring up to five consultations before a diagnosis is made.
Adult patients with IBS-C have been shown to not only have a significantly lower level of health-related quality of life compared with healthy individuals, but also similar to patients with asthma, migraine, and other different disease states. (3, 5, 6)
Prior to the approval of Constella, IBS-C treatment options consisted mainly of therapies for individual symptoms such as antispasmodics or unlicensed antidepressants for pain and laxatives for constipation3.
“Thousands of adult patients are seeking help for IBS-C symptoms such as abdominal discomfort and constipation and, up until now, there was no specific prescription treatment available for their disease. Through the combined efforts of many people, we now have the ability to provide relief to many of these adult patients”, said Luciano Conde, Chief Operating Officer at Almirall. “This condition also causes significant distress and economic cost to patients and poses a considerable economic burden in Europe overall.” (7)
“Bringing linaclotide to appropriate patients worldwide is an important aspect of Ironwood’s mission,” said Tom McCourt, Chief Commercial Officer at Ironwood. “Building on our strong initial launch of linaclotide in the U.S., we now hope to make a difference in the lives of adult European IBS-C patients suffering from this prevalent and very bothersome condition.”
The SMC Resolution
Also, yesterday, the Scottish Medicines Consortium (SMC) recommended Constella® for adult patients with moderate to severe IBS-C who have not responded adequately to or cannot tolerate other suitable treatment options. The SMC clinical experts highlighted an unmet need in this patient group and accepted the use of Constella® within NHS Scotland. Experts welcome “an additional symptomatic treatment for IBS-C in an area where there is a lack of documented, reliable and licensed treatment options”.
Constella® was approved in November 2012 by the European Commission, and it is under registration for regulatory approval in Switzerland.
