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

Endpoints Met for RECORD1 and RECORD2 Trials in Total Hip Replacement Surgery

Berlin, November 9, 2007 - Findings from three phase III clinical trials 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. 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 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.

Rivaroxaban is being jointly developed by Bayer HealthCare AG and Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

Copies of abstracts are available and can be viewed online at the ASH website: www.hematology.org/meetings/abstracts.cfm Information that goes beyond what is contained in the abstract is embargoed until the start time of the official annual meeting presentation.

Data from the RECORD (REgulation of Coagulation in major Orthopaedic surgery reducing the Risk of DVT and PE) phase III clinical trial program will be presented during the ASH meeting as follows:

Upon regulatory approval for the prevention of venous thromboembolism (VTE) after major orthopedic surgery of the lower limbs, rivaroxaban will be commercialized in Europe by Bayer Schering Pharma. The companies plan to file rivaroxaban for a similar indication in the United States in 2008, where if approved, it will be commercialized by Scios Inc. and Ortho-McNeil, Inc., both of which are Johnson & Johnson companies.

The trade name of rivaroxaban is expected to be Xarelto®, pending health authority approval.
