PRESS RELEASE

Pentaglobin(R) showed encouraging results in the treatment of donor
specific antibodies after lung transplantation

- In lung transplantation early new donor specific antibodies (DSA) are
risk factors for mortality and graft rejection

- Pentaglobin showed very good efficacy in patients who showed early DSA
development after lung transplantation

- Patients with early new DSA but treated with Pentaglobin(R) have
midterm survival and lung function comparable to patients not
developing DSA at all

- Relative mortality rate reduction of over 70%

Dreieich, 14 January 2016. In lung transplantation early new donor specific
antibodies (DSA) are risk factors for mortality, and acute and chronic
graft rejection. About 20-30% of all lung transplantation patients develop
DSA. Hence, DSA treatment seems to be justified albeit to date, no standard
treatment is established in lung transplantation. In a recently published
study conducted in Hannover Medical School, Germany, it was shown that
patients treated with Pentaglobin(R) (IgM / IgA enriched immunoglobulin)
with early DSA development after lung transplantation had a significantly
higher survival rate than patients treated with therapeutic plasma
exchange.

In the Pentaglobin(R) group (56 patients) the survival rate of 94% after
one year was comparable to patients without DSA (180 patients) and much
higher than in the historic therapeutic plasma exchange group (57 patients)
with a survival rate of 79%. Already after one year the relative mortality
rate was reduced more than 70%.

'The magnitude of the difference between the two treatment strategies was
more pronounced than we expected. The mortality risk caused by DSA after
lung transplantation was significantly reduced with IgM / IgA enriched
immunoglobulin.' stated Prof Dr Gregor Warnecke, principle investigator of
the study.

Pentaglobin(R) therapy yielded superior DSA clearance (92%), which
persisted long term and was significantly better than that in therapeutic
plasma exchange treated patients (64%). Additionally the Pentaglobin(R)
patients showed less infections requiring hospitalization and improved
early freedom from bronchiolitis obliterans syndrome (inflammatory disease
of the small airways, in which a scarring process leads to a progressive
closure), major cause for graft failure and re-transplantation.

These encouraging results justify evaluating the potential of IgM / IgA
enriched immunoglobulins in additional indications. Biotest has recently
completed a phase II trial for the newly developed IgM / IgA enriched IgM
Concentrate (BT-086) and is currently planning the further development in a
phase III trial.

About Pentaglobin(R)
Pentaglobin(R) is the first and only IgM-enriched immunoglobulin
preparation for intravenous use. Pentaglobin(R) significantly increases the
survival rate of patients with severe bacterial infections and acts against
a broad spectrum of bacterial pathogens. Pentaglobin's(R) mode of action,
is both anti-bacterial by fast neutralization of bacterial endo- and
exotoxins and anti-inflammatory by scavenging excessively activated
complement factors. Pentaglobin(R) is licensed in several countries, mainly
for the treatment of severe bacterial infections in combination with
antibiotics.
