European Label Update of Bayer's Xarelto® Now Including Guidance for Use in Patients with Atrial Fibrillation Undergoing Cardioversion

Label update based on positive CHMP opinion issued in December 2014
Berlin, January 20, 2015 - Bayer HealthCare today announced the inclusion of
specific guidance for doctors treating patients with non-valvular atrial
fibrillation (AF) undergoing cardioversion to the European Xarelto®
(rivaroxaban) Product Information. This label update provides physicians with
important information on the clinical utility of rivaroxaban in patients with
AF who require cardioversion and is based on the positive CHMP opinion issued
in December 2014. It makes Xarelto the only novel oral anticoagulant with
specific label guidance for both early and delayed cardioversion.

"Providing adequate anticoagulation therapy for patients with AF undergoing
cardio-version is important. With warfarin, patients will often move in and out
of the therapeutic range for optimal anticoagulation often requiring
postponement of their procedure or leading to increased risk of thromboembolic
events like stroke," said Dr Riccardo Cappato, M.D., Arrhythmia and
Electrophysiology Center, University of Milan, IRCCS Policlinico San Donato,
San Donato Milanese, Milan, Italy and Co-Principal Investigator of the X-VeRT
study. "The Xarelto label update provides physicians with clear guidance for
patients with atrial fibrillation undergoing cardioversion. The X-VeRT study
showed Xarelto to be an effective and well-tolerated alternative to vitamin K
antagonists with a practical advantage over VKAs."

The label update is based on findings from the X-VeRT study, the first
prospective trial of a novel oral anticoagulant in 1,504 patients with AF
undergoing cardioversion. The results from X-VeRT showed that compared with the
use of VKA, rivaroxaban was associated with a numerical reduction in the risk
of cardiovascular events of 50 per cent in the composite primary efficacy
outcome of stroke, transient ischaemic attack, peripheral embolism, myocardial
infarction and cardiovascular death (0.5% vs. 1.0%; risk reduction: 0.50; 95%
confidence interval: 0.15-1.73), with a numerically lower risk of major
bleeding of 24 per cent in the primary safety outcome (0.6% vs. 0.8%; risk
reduction 0.76; 95% confidence interval: 0.21-2.67). The practical advantage of
using rivaroxaban was demonstrated by the shorter time to cardioversion
compared to VKA, particularly in patients scheduled for delayed cardioversion.
The study, published in the European Heart Journal in September 2014, was
designed to supplement previous findings of rivaroxaban from ROCKET AF and was
not powered for statistical significance.

About Cardioversion in Patients with AF

Patients with AF experience an irregular heartbeat which causes turbulent blood
flow that can lead to the formation of blood clots. Cardioversion is a common
medical procedure undertaken to restore the heartbeat from AF back to its
regular sinus rhythm. Without adequate anticoagulation, these patients are at
risk of thromboembolic complications, with stroke rates of 5-7 per cent.
Current guidelines recommend at least three weeks of effective anticoagulation
with VKAs (target INR 2.0-3.0) prior to cardioversion (or less if a
transesophageal echocardiogram has revealed no thrombus in the left atrial or
left atrial appendage) and four weeks of oral anticoagulation after the
procedure.

About the X-VeRT Study

X-VeRT was a prospective, randomised, open-label, parallel group Phase IIIb
study involving 1,504 patients with hemodynamically stable non-valvular atrial
fibrillation of > 48 hours or unknown duration, recruited from 16 countries.
Anticoagulation naïve or experienced patients scheduled for cardioversion were
randomly assigned to rivaroxaban 20mg once daily (15mg once daily if creatinine
clearance was between 30 and 49 mL/min) or INR-adjusted VKA therapy (target INR
2.0-3.0) in a 2:1 ratio. The decision regarding early cardioversion (a goal of
between 1-5 days of rivaroxaban or usual VKA therapy before the procedure) or
delayed cardioversion (rivaroxaban or VKA for 3-8 weeks prior to the procedure)
was taken by the local investigator.

The X-VeRT study contributes to the extensive investigation program of
rivaroxaban. After its completion, the program will include more than 275,000
patients in clinical trials and real world settings.

About Xarelto® (Rivaroxaban)

Rivaroxaban is the most broadly indicated novel oral anticoagulant and is
marketed under the brand name Xarelto®. Xarelto is approved for five
indications across seven distinct areas of use, protecting patients across more
venous and arterial thromboembolic (VAT) conditions than any other novel oral
anticoagulant:

- The prevention of stroke and systemic embolism in adult patients with
non-valvular atrial fibrillation (AF) with one or more risk factors

- The treatment of deep vein thrombosis (DVT) in adults

- The treatment of pulmonary embolism (PE) in adults

- The prevention of recurrent DVT and PE in adults

- The prevention of venous thromboembolism (VTE) in adult patients undergoing
elective hip replacement surgery

- The prevention of VTE in adult patients undergoing elective knee replacement
surgery

- The prevention of atherothrombotic events (cardiovascular death, myocardial
infarction or stroke) after an Acute Coronary Syndrome in adult patients with
elevated cardiac biomarkers and no prior stroke or transient ischaemic attack
(TIA) when co-administered with acetylsalicylic acid (ASA) alone or with ASA
plus clopidogrel or ticlopidine

Whilst licences may differ from country to country, across all indications
Xarelto is approved in more than 125 countries.

Rivaroxaban was discovered by Bayer HealthCare, and is being jointly developed
with Janssen Research & Development, LLC. Xarelto is marketed outside the U.S.
by Bayer HealthCare and in the U.S. by Janssen Pharmaceuticals, Inc. (a Johnson
& Johnson Company).

Anticoagulant medicines are potent therapies used to prevent or treat serious
illnesses and potentially life-threatening conditions. Before initiating
therapy with anticoagulant medicines, physicians should carefully assess the
benefit and risk for the individual patient.
Responsible use of Xarelto is a very high priority for Bayer, and the company
has developed a Prescribers Guide for physicians and a Xarelto Patient Card for
patients to support best practice.
