Shire plc: Lialda® (Mesalamine) Now Approved in U.S. for Maintenance of Remission of Ulcerative Colitis

PHILADELPHIA, July 18, 2011 /PRNewswire/ --

- Lialda has been indicated for the induction of remission in patients with active, mild to moderate ulcerative colitis and is now also approved for the maintenance of remission of ulcerative colitis

Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) approved Lialda^® (mesalamine) Delayed Release Tablets for the maintenance of remission in patients with ulcerative colitis. This approval is based on results from a six-month study demonstrating the safety and effectiveness of Lialda in maintaining endoscopic remission in adult patients. This approval follows the previous indication of Lialda approved by the FDA in 2007 for the induction of remission in patients with active, mild to moderate ulcerative colitis.

"At Shire, we strive to create meaningful therapies for patients with our clinical programs, and this approval based on our large clinical trial underscores our commitment and dedication to the ulcerative colitis community," said Roger Adsett, Senior Vice President of Shire's Gastrointestinal business. "This new indication is an important milestone for Lialda as it provides a once-daily option for both inducing remission in patients with active, mild to moderate ulcerative colitis and maintaining remission of ulcerative colitis."  

Lialda's new indication is based on results from a multicenter, randomized, double-blind, active comparator, non-inferiority study conducted in 826 adult patients in remission from ulcerative colitis. Maintenance of remission was assessed using a modified Ulcerative Colitis Disease Activity Index (UC-DAI) and was based on maintaining endoscopic remission defined as a modified UC-DAI endoscopy subscore of less than or equal to 1. The endoscopy subscore of less than or equal to 1 represented normal or mild disease with no friability.

Of the patients receiving Lialda 2.4 g/day (n=343) administered once daily, 83.7% maintained remission at Month 6, which was similar to that seen using the comparator, mesalamine delayed-release 1.6 g/day (n=336) administered as 0.8 g given twice daily (81.5%; 95% confidence interval for difference: -3.9%, 8.1%).

Safety of Lialda in the maintenance of remission of ulcerative colitis was evaluated in three studies, one being the six-month, double-blind, non-inferiority, comparator study and two being 12- to 14-month open-label studies. The most common adverse reactions with Lialda in the maintenance arms of these three trials were ulcerative colitis, headache, abnormal liver function test and abdominal pain. The most common severe adverse reactions were gastrointestinal disorders, most of which are consistent with symptoms associated with ulcerative colitis.

In 2007, Lialda gained FDA approval for the induction of remission in patients with active, mild to moderate ulcerative colitis as a result of two eight-week, placebo-controlled clinical studies demonstrating safety and effectiveness.

Important Safety Information

You should not take Lialda if you are allergic to salicylates (including mesalamine, aspirin, or aspirin-containing products) or to any of the ingredients of Lialda.  

Reports of problems with kidney function have been associated with mesalamine-containing products like Lialda. Tell your doctor if you have or have had problems with your kidneys. It is recommended that all patients have their kidney function checked before starting Lialda and periodically while on therapy.

Products that contain mesalamine, like Lialda, have been associated with a condition that may be difficult to distinguish from an ulcerative colitis flare-up. Symptoms include cramping, stomach ache, bloody diarrhea, fever, headache, and rash. If you experience any of these symptoms, talk to your doctor immediately. Your doctor may decide to discontinue your medication.  

Tell your doctor if you are allergic to sulfasalazine, as you may also be allergic to Lialda or drugs that contain or are converted to mesalamine. Some patients taking Lialda or mesalamine-containing products have reported heart-related allergic reactions, such as inflammation of the heart muscle and inflammation of the lining of the heart.  Tell your doctor if you have or have had a history of myocarditis or pericarditis as this may predispose you to these types of reactions.  

Reports of liver failure have been associated with mesalamine-containing products like Lialda in patients that have or have had liver disease. Tell your doctor if you have a problem with your liver.

Tell your doctor if you have a stomach blockage, as this may delay the release of medication.

In clinical trials, common side effects reported with Lialda included ulcerative colitis, headache, gas, abnormal liver function test results, and stomach ache. Inflammation of the pancreas was reported which in some cases led to discontinuation of Lialda therapy. Other side effects may occur.  

Before starting Lialda, tell your doctor about all medications you are taking.  Mesalamine may increase the risk of kidney problems when used with non-steroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen, naproxen). Mesalamine may increase the risk of blood disorders when used with azathioprine and 6-mercaptopurine.

About Ulcerative Colitis
Ulcerative colitis is a type of inflammatory disease. It only affects the colon, producing chronic inflammation and sometimes sores or ulcers along the inside lining of the colon.

Currently, there is no cure available with medical treatment, and the cause of the disease is unknown.
