Salix Secures Additional Intellectual Property Relating to Rifaximin
RALEIGH, N.C.--(BUSINESS WIRE)-- Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that Cipla Limited has granted Salix exclusive rights under certain patent applications in the "Rifaximin Complexes" patent family controlled by Cipla. The grant is on a worldwide basis, excluding the countries of Asia (other than Japan) and Africa. Additionally, Salix and Cipla have expanded the scope of their 2009 exclusive license agreement whereby Cipla granted Salix exclusive rights in the United States, Canada and Mexico under certain patent rights covering amorphous rifaximin. By means of this amendment to the 2009 agreement, the rights already licensed to Salix in the United States, Canada and Mexico are expanded to include certain patent rights in the European Union, Japan, Australia, New Zealand and South Korea. Salix is required to make an up-front payment and, upon achievement, additional regulatory milestone payments to Cipla in respect of the new license agreement regarding the "Rifaximin Complexes" patent rights. Salix also will pay royalties on net sales of products covered by the "Rifaximin Complexes" patents licensed to Salix.
About XIFAXAN 550 mg
XIFAXAN® (rifaximin) 550 mg tablets are indicated for reduction in risk of overt hepatic encephalopathy (HE) recurrence in patients ≥ 18 years of age.
Important Safety Information about XIFAXAN 550 mg
XIFAXAN® (rifaximin) 550 mg tablets are contraindicated in patients with a hypersensitivity to rifaximin, any of the 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. Treatment with antibacterial agents alters the normal flora of the colon which may lead to overgrowth of C. difficile. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued.
There is increased systemic exposure in patients with more severe hepatic dysfunction. The clinical trials were limited to patients with MELD scores < 25. Therefore, caution should be exercised when administering XIFAXAN to patients with severe hepatic impairment (Child-Pugh C).
Concomitant administration of drugs that are P-glycoprotein (P-gp) inhibitors with XIFAXAN can substantially increase the systemic exposure to XIFAXAN. Caution should be exercised when concomitant use of XIFAXAN and a P-gp inhibitor such as cyclosporine is needed. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P-gp inhibitors may further increase the systemic exposure to XIFAXAN.
Based on animal data, XIFAXAN may cause fetal harm. Discontinue in nursing mothers after taking into account the importance of the drug to the mother.
The most common adverse reactions occurring in ≥ 10% of patients and at a higher incidence than placebo in the clinical study were peripheral edema (15%), nausea (14%), dizziness (13%), fatigue (12%), and ascites (11%).
