Bayer to Present Latest Data on Its Hematology and Oncology Portfolio

Three-year results from the Phase III SPINART study for octocog alfa (Kogenate® FS) in patients with hemophilia A / New data on damoctocog alfa pegol (BAY 94-9027) for the treatment of hemophilia A / Presentations on copanlisib and sorafenib in patients with different hematological cancers
Leverkusen, December 1, 2014 - Bayer HealthCare will present latest data from
its hematology and oncology portfolio at the American Society of Hematology
(ASH) 56th Annual Meeting, December 6-9, 2014, in San Francisco, CA. The
presentations will describe the results from a Phase III study with octocog
alfa (approved for hemophilia A under the trade name of Kogenate® FS (Kogenate
® Bayer in the EU)) as well as clinical and non-clinical results on damoctocog
alfa pegol (BAY 94-9027) for hemophilia A therapy. Also, Phase II clinical
trials results with sorafenib (approved for various indications relating to
cancer of the liver, the kidney and the thyroid under the trade name Nexavar®)
and copanlisib are presented for the treatment of different hematological
cancers.

The presented data on Bayer's products include two oral presentations. One
presentation will discuss the three-year findings from the Phase III SPINART
study for antihemophilic treatment with octocog alfa. The SPINART study
evaluated the secondary propylaxis with octocog alfa on bleeding frequency and
joint damage compared to episodic treatment in adults with severe hemophilia A.
The other oral presentation will show the results of an independent
investigator-sponsored randomized study of Dresden University and the
Studienallianz Leukämie (SAL) with sorafenib in combination with standard
chemotherapy for the treatment of acute myeloid leukemia.

The following studies evaluating Bayer's products will be presented at ASH 2014:

About Octocog alfa (Kogenate® FS/Kogenate® Bayer)

Octocog alfa, human coagulation factor VIII or antihemophilic factor, is the
active substance in Kogenate® FS (Kogenate® Bayer in Europe), which is approved
in more than 90 countries worldwide. In most countries, Kogenate® FS is
approved for the treatment and prevention of bleeding in adults and children
with hemophilia A, an inherited bleeding disorder.
Patients with hemophilia A lack coagulation factor VIII, which causes blood
clotting problems such as bleeding in the joints, muscles and internal organs.
Kogenate® FS is used to correct the factor-VIII deficiency by replacing the
missing factor VIII, giving temporary control of the bleeding disorder.
The human coagulation factor VIII in Kogenate® FS is not extracted from human
blood but is produced by a method known as 'recombinant DNA technology'.

About Damoctocog alfa pegol (BAY 94-9027)

The investigational product damoctocog alfa pegol (BAY 94-9027) is a
site-specific PEGylated recombinant Factor VIII (rFVIII). PEGylation of the
clotting factor is intended to slow-down the clearance of Factor VIII in the
body, thus extending its plasma half-life. BAY 94-9027 is currently in Phase
III clinical development for the treatment and prophylaxis of bleeding in
patients with hemophilia A.

About Copanlisib

Currently in clinical Phase II, the investigational agent copanlisib is a novel
pan-class I inhibitor of phosphatidylinositol 3-kinase (PI3K) with a
predominant activity against both PI3K-? (delta) and PI3K-? (alpha) isoforms.
Copanlisib has shown promising early clinical signals in Phase I and II studies
in heavily pretreated patients with indolent and aggressive B cell lymphomas.
The intravenous small molecule inhibitor is one of the five new promising drug
candidates, which should be ready by 2015 for a decision on advancement to
Phase III.

About Sorafenib

Sorafenib, an oral anti-cancer therapy, is approved under the brand name
Nexavar® in more than 100 countries worldwide. In Europe, Nexavar® is approved
for the treatment of hepatocellular carcinoma (HCC); for the treatment of
patients with advanced renal cell carcinoma (RCC) who have failed prior
interferon-alpha or interleukin-2 based therapy or are considered unsuitable
for such therapy; and for progressive, locally advanced or metastatic,
differentiated (papillary/follicular/Hürthle cell) thyroid carcinoma,
refractory to radioactive iodine.
In preclinical studies, sorafenib has been shown to inhibit multiple kinases
thought to be involved in both cell proliferation (growth) and angiogenesis
(blood supply) - two important processes that enable cancer growth. These
kinases include Raf kinase, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 and
RET.
Nexavar® is co-developed by Onyx Pharmaceuticals, Inc., an Amgen subsidiary,
and Bayer, except in Japan where Bayer manages all development. The companies
co-promote Nexavar® in the U.S. Outside of the U.S., excluding Japan, Bayer has
exclusive marketing rights, and Bayer and Onyx share profits globally.
