Medtronic Receives FDA Marketing Clearance for Complete SE Biliary Stent System

Medtronic, Inc. (NYSE: MDT), announced today that it has received 510(k) marketing clearance from the U.S. Food and Drug Administration for the Complete SE (self-expanding) Biliary Stent System, which is indicated for use in the palliative treatment of malignant neoplasms in the biliary tree – cancerous tumors in the bile duct that can compromise digestion by restricting the flow of digestive fluids.

U.S. commercial sales of the new biliary stent will begin immediately in a wide size range, with diameters of 4 – 10 mm and lengths of 20 – 150 mm.

Bench testing has shown the Complete SE Biliary Stent System to be extremely accurate in terms of stent placement. Accurate stent placement can decrease the likelihood that additional stents are necessary to cover the entire narrowing of the bile duct.

The safety and effectiveness of this device in the vascular system have not been established.

Invitrogen and CytRx Subsidiary RXi Pharmaceuticals Collaborate to Enhance RNAi Technologies for Therapeutic Applications

Invitrogen Corporation (NASDAQ:IVGN), a provider of essential life science technologies for research, production and diagnostics, and CytRx Corporation's (NASDAQ:CYTR) majority-owned subsidiary RXi Pharmaceuticals Corporation (RXi) today announced that they have entered into an agreement whereby RXi will exclusively license second generation RNA interference (RNAi) technology from Invitrogen for designated target genes in all human therapeutic categories.

Invitrogen's patent applications that are part of this agreement cover Stealth™ and other proprietary technologies related to enhanced configurations of chemically modified double-stranded RNA. Terms of the agreement were not disclosed.

“Licensing this broad technology from Invitrogen is part of our strategy to continually enhance our proprietary rxRNA™ compounds for therapeutic applications,” said Dr. Tod Woolf, President and Chief Executive Officer of RXi.

“Currently Invitrogen Stealth™ RNAi synthetic duplexes are widely used for RNAi research across both in vitro and in vivo applications due to their specificity, efficacy and stability,“ said Amy Butler, Invitrogen vice president of gene expression profiling.“We see the use of our Stealth™ RNAi technology in therapeutics as a natural next step in Invitrogen's efforts to be at the cutting edge of in vivo gene regulation.“

The Company owns three clinical-stage compounds based on its small molecule "molecular chaperone" co-induction technology. In September 2006, CytRx announced that arimoclomol was shown to be safe and well tolerated at all three doses tested in its Phase IIa clinical trial in patients with ALS. The Company plans to enter a Phase IIb clinical trial with arimoclomol in ALS in 2007, subject to U.S. Food and Drug Administration (FDA) clearance. The FDA has granted Fast Track designation and Orphan Drug status to arimoclomol for the treatment of ALS, which has also been granted orphan medicinal product status for the treatment of ALS by the European Commission. The Company has announced plans to commence a Phase II clinical trial for arimoclomol in stroke recovery in the first half of 2008, subject to FDA clearance. The Company has also announced plans to commence a Phase II clinical trial with its next drug candidate, iroxanadine, for diabetic foot ulcers in the first half of 2008, subject to FDA clearance. CytRx has recently opened a research and development facility in San Diego. For more information on the Company, visit www.cytrx.com.

New Phase III Trial Results for Rivaroxaban to be Presented at the 49th Annual Meeting of the American Society of Hematology

Findings from three phase III clinical trials of rivaroxaban will be presented in the plenary session and during oral presentations at the American Society of Hematology (ASH) Annual Meeting in Atlanta, Georgia, from December 8 to 11, 2007. Rivaroxaban is being jointly developed by Johnson & Johnson Pharmaceutical Research & Development, L.L.C. and Bayer HealthCare, AG.

The studies evaluated rivaroxaban in head-to-head comparison with enoxaparin, the current standard of care, for the prevention of venous thromboembolism (VTE) in patients undergoing major orthopaedic surgery. The presentations will highlight results from the recently-completed RECORD1 (Regulation of Coagulation in major Orthopaedic surgery reducing the Risk of DVT and PE) and RECORD2 studies in total hip replacement surgery as well as additional data from the RECORD3 trial, which evaluated rivaroxaban in total knee replacement surgery. Copies of the following abstracts can be viewed online at the ASH website: www.hematology.org/meetings/abstracts.cfm.

Oral Rivaroxaban Compared with Subcutaneous Enoxaparin for Extended Thromboprophylaxis after Total Hip Arthroplasty: The RECORD1 Trial Abstract# 6. Plenary presentation: Sunday, Dec. 9, 3:10 p.m., Hall A1, Georgia World Congress Center
Extended Thromboprophylaxis with Rivaroxaban Compared with Short-Term Thromboprophylaxis with Enoxaparin After Total Hip Arthroplasty: The RECORD2 Trial
Abstract# 307. Oral presentation: Monday, Dec. 10, 11:00 a.m., Rooms B312-B313a
