Bayer to Present Latest Clinical Data in the Area of Kidney Diseases

ARTS-DN-Phase IIb-study results of finerenone in diabetic nephropathy and early clinical data on molidustat
Leverkusen, March 11, 2015 - Bayer HealthCare will present latest clinical data
on development candidates in the area of kidney diseases at the World Congress
of Nephrology (WCN), March 13-17, 2015, in Cape Town, South Africa. An oral and
poster presentation will describe the results from the Phase IIb ARTS-DN study
with finerenone for the treatment of patients with diabetic nephropathy. Early
clinical results on molidustat in patients with anemia and chronic kidney
disease will also be presented. A Bayer sponsored lunch symposium will give
insight into unmet needs in renal therapies with a focus on ways forward in
diabetic kidney disease and renal anemia.

About Finerenone

Finerenone (BAY 94-8862) is a novel potent and selective oral non-steroidal
mineralo-corticoid receptor (MR) antagonist blocking deleterious effects of
aldosterone. Increased activation of the MR leads to pathological changes in
the heart and kidneys, which can be prevented by effective MR antagonism.
Current steroidal MR antagonists on the market have proven to be effective in
reducing cardiovascular mortality in patients with heart failure (HF). However,
they are underutilized due to the incidence of hyperkalemia, renal dysfunction,
and anti-androgenic / progestonal side effects. Finerenone has demonstrated a
promising efficacy and safety profile in preclinical studies as well as in
Phase IIa (ARTS study). The MR antagonist is currently in clinical Phase IIb
development for the treatment of worsening chronic heart failure and diabetic
nephropathy and is currently expected to enter clinical Phase III end of 2015.

About Molidustat

Molidustat (BAY 85-3934) is a novel inhibitor of hypoxia-inducible factor (HIF)
prolyl hydroxylase (PH), an enzyme which stimulates erythropoietin (EPO)
production and the formation of red blood cells. Phase I data have shown that
inhibition of HIF-PH by Molidustat results in an increase in endogenous
production of EPO. A Phase IIb program with Molidustat is currently ongoing in
patients with anemia associated with chronic kidney disease and/or end-stage
renal disease.

About Diabetic Nephropathy

Continuously increased sugar levels in the blood of diabetic patients can
damage the kidneys. Kidney performance (the so-called glomerular filtration
rate or GFR) is reduced, and in addition the damaged kidney loses increased
amounts of protein in the urine (albuminuria). Over time, the kidneys may fail
completely. Without either regular dialysis or a kidney transplant, kidney
failure is always fatal. Diabetic nephropathy is the most common cause of
kidney failure world-wide.

About Anemia in Chronic Kidney Disease

Anemia associated with chronic kidney disease and/or end-stage renal disease is
a major cause of anemia in industrialized countries. The diseased kidneys do
not produce sufficient levels of the hormone erythropoietin (EPO) resulting in
insufficient production of red blood cells and anemia. Molidustat stabilizes
HIF (hypoxia inducible factor), a protein associated with EPO production, which
leads to an increase of endogenous EPO production.

About Cardiology at Bayer

Bayer is committed to delivering Science For A Better Life by advancing a
