Salix And Alfasigma Will Initiate Late-Stage Program To Study Rifaximin In Patients With Postoperative Crohn's Disease
According to the Crohn's & Colitis Foundation, more than 750,000 Americans have Crohn's disease, and of those, up to 75 percent will eventually require surgery. Surgery in Crohn's disease is not curative, and postoperative recurrence frequently occurs.1
"Today, there are no approved treatments in the United States for the prevention of postoperative Crohn's disease recurrence. Based on existing clinical data, we believe rifaximin may be a potential treatment solution to help postoperative patients manage their Crohn's disease," said Mark McKenna, president of Salix Pharmaceuticals. "The amended agreement with Alfasigma allows us to start working together on a clinical research program that could lead to a new option in the treatment paradigm for postoperative Crohn's disease patients."
The new formulation of rifaximin, called Extended Intestinal Release (EIR), will be used in the late-stage clinical research program. In 2012, a European clinical Phase 2 study in 402 patients with moderately active Crohn's disease was performed to assess the efficacy and safety of multiple doses of rifaximin-EIR. The Phase 2 trial demonstrated that administration of rifaximin-EIR twice daily for 12 weeks induced remission with few adverse events in patients with moderately active Crohn's disease.2
"I am very happy regarding this agreement with Salix as it re-energizes our long-term partnership, one that has played a critical role in the success of XIFAXAN® (rifaximin) in the United States," commented Anton Giorgio Failla, executive director of Corporate Development, Alfasigma. "We look forward to dedicating our efforts to develop a new generation of rifaximin that may improve patients' lives and address a significant unmet medical need."
Resolution of the Arbitration
The companies have agreed to resolve the outstanding arbitration regarding performance under an Amended and Restated License Agreement between Alfasigma and Salix concerning another development project for a new formulation of rifaximin. As a result of the resolution, all claims related to the arbitration will be released.
About XIFAXAN
XIFAXAN® (rifaximin) 550 mg tablets are indicated for the reduction in risk of overt hepatic encephalopathy (HE) recurrence in adults and for the treatment of irritable bowel syndrome with diarrhea (IBS-D) in adults.
IMPORTANT SAFETY INFORMATION
- XIFAXAN is contraindicated in patients with a hypersensitivity to rifaximin, rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis.
- Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued.
- There is an increased systemic exposure in patients with severe (Child-Pugh Class C) hepatic impairment. Caution should be exercised when administering XIFAXAN to these patients.
- Caution should be exercised when concomitant use of XIFAXAN and P-glycoprotein (Pgp) and/or OATPs inhibitors is needed. Concomitant administration of cyclosporine, an inhibitor of P-gp and OATPs, significantly increased the systemic exposure of rifaximin. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P-gp inhibitors may further increase the systemic exposure to rifaximin.
- In clinical studies, the most common adverse reactions for XIFAXAN were: o HE (≥10%): Peripheral edema (15%), nausea (14%), dizziness (13%), fatigue (12%), and ascites(11%) o IBS-D (≥2%): Nausea (3%), ALT increased (2%).
- INR changes have been reported in patients receiving rifaximin and warfarin concomitantly. Monitor INR and prothrombin time. Dose adjustment of warfarin may be required. • XIFAXAN may cause fetal harm. Advise pregnant women of the potential risk to a fetus.
