Saizen(R) Solution For Injection Eliminates the Need to Reconstitute Powder for Injection

GENEVA, Switzerland, November 15, 2010 - Merck Serono, a division of Merck KGaA, Darmstadt, Germany,
announced today that it has successfully completed the Decentralized
Procedure (DCP) allowing for approval of Saizen(R) Solution For Injection
(somatropin) in the 18 participating Member States[1]. Marketing
authorizations enabling commercial sales in the individual countries are
expected over the next several months.

Saizen(R) Solution For Injection is a liquid formulation of
Merck Serono's recombinant growth hormone Saizen(R) indicated in Europe for
the treatment of growth hormone deficiency in children and adult patients, as
well as for growth promotion in Children Born Small for Gestational Age, and
in children with Turner Syndrome or Chronic Renal Failure. To accommodate
individual patient needs, the new formulation will be available in cartridges
of 6 mg, 12 mg and 20 mg, designed for exclusive use with Merck Serono's
electronic injection device easypod(TM) and needle-free auto-injector 2.

"Since the launch of Saizen, Merck Serono has continuously
developed new options to facilitate the delivery of Saizen therapy. Used in
conjunction with easypod, the different cartridge options for Saizen Solution
For Injection offer the flexibility to administer in a single injection a
wide range of doses from 0.15 mg to 6.4 mg, which is the highest dose
available in Europe for a liquid formulation. This flexibility allows
physicians to tailor recombinant growth hormone treatment to patient
individual needs," said Fereydoun Firouz, Head of the Merck Serono Global
Business Unit Fertility and Endocrinology.

"Adherence to treatment is one of the most important factors
behind success of growth hormone treatment and I believe that simplifying the
injection process can help patient be more adherent with their treatment
regimen," said Professor Pierre Chatelain, of Hôpital Mère-Enfant (Claude
Bernard University, Lyon, France). "The introduction of Saizen Solution For
Injection coupled with the use of easypod allows patients to manage their
daily injection and healthcare professionals to assess growth using accurate
patient injection information. He added: "easypod is the only device that
records patient injections."

In Europe, the launch of Saizen(R) Solution For Injection will
be rolled out in the course of 2011 following the granting of the national
marketing authorizations.

Saizen(R) Solution For Injection is not available in the
United States

About Growth Hormone Deficiency (GHD)

Growth hormone deficiency occurs when the pituitary gland in
the brain is unable to release or produce adequate amounts of growth hormone.
In children, growth hormone deficiency causes slow growth, and without
treatment, few will reach their full height potential as an adult.

It is estimated that the incidence of growth hormone
deficiency in children is between 1 in 4,000 and 1 in 10,000.

Adult growth hormone deficiency can also be a significant
problem which affects 3 in 10.000 each year. It is recognized as a specific
clinical syndrome.
