Under the terms of the agreement, Teva will make a one-time payment to Novartis in addition to an ongoing royalty on U.S. sales of the generic product.

Philippine Court denies Pfizer petition to block generic Variant

A LOCAL court has denied Pfizer Inc.'s bid to stop the sale of a generic version of anti-hypertensive drug Variant manufactured by Philippine drug-maker United Laboratories Inc. (Unilab). In a statement, Pfizer said it would ask the court to reconsider its ruling on the generic version of Atorvastatin Calcium. Pfizer and co-plaintiff Warner Lambert Co. LLC had filed a patent infringement case against Unilab in October last year. Pfizer said it owns the Philippine patent of Atorvastatin Calcium, adding this patent would expire in 2012. The drug is sold by the company under the brand name Lipitor. Unilab and its sister company Therapharma Inc. also in October last year had released Avamax, a generic version of Atorvastatin. Unilab had also filed an invalidation case against Pfizer's Atorvastatin patent before the Intellectual Property Office of the Philippines in July last year, but this case is still pending.

Teva sends ANDA certificate notification to Gilead Sciences for Viread

Gilead Sciences announced receipt of a Paragraph IV Certification Notice Letter advising that Teva Pharmaceuticals submitted an ANDA to the USFDA requesting permission to manufacture and market a generic version of Viread^® (tenofovir disoproxil fumarate). In the notice letter, Teva alleges that three patents associated with tenofovir disoproxil – US Patent Numbers 5,922,695; 5,977,089; and 6,043,230; and one patent associated with tenofovir disoproxil fumarate – US Patent Number 5,935,946 – owned by Gilead Sciences are invalid, unenforceable and/or will not be infringed by Teva's manufacture, use or sale of the product described in its ANDA submission. 

Gilead is currently reviewing the Notice Letter and has 45 days from the date of receipt to commence a patent infringement lawsuit against Teva. Such a lawsuit would restrict the FDA from approving Teva's ANDA for up to 30 months or until a district court decision that is adverse to Gilead, whichever occurs first. Viread is currently protected by four patents, which are listed in the FDA's Approved Drug Products List, and all four patents would need to be invalidated or expired before a generic version of Viread could be marketed. The USPTO confirmed the patentability of these four Viread patents in 2008.

Gilead currently has a lawsuit pending against Teva in response to Teva's attempts to seek approval for generic versions of Truvada^® (emtricitabine and tenofovir disoproxil fumarate) and Atripla^® (efavirenz 600 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg) based on allegations that two emtricitabine patents are invalid, unenforceable and/or will not be infringed by Teva's manufacture, use or sale of its generic product.
