Change of in-use storage for Saizen Liquid, a recombinant human Growth

Hormone

Storage for up to seven days at 25°C now possible

Darmstadt, Germany, April 15, 2015 - Merck Serono, the biopharmaceutical business of Merck, today announced a change in the in-use storage condition for Saizen® solution for injection (6mg, 12mg and 20mg). Saizen is a recombinant human Growth Hormone (r-hGH) indicated for the treatment of growth hormone deficiency (GHD) in children and adults, Turner Syndrome, chronic renal failure and children born short for gestational age (SGA).

The label change for in-use storage gives patients the possibility to keep the product for up to seven consecutive days at room temperature (25°C). After first injection the Saizen cartridge has to be used within 28 days, until now it needed to be stored at

2-8°C during this whole period.1 The change has been made to improve patient

convenience, for example making the medicine easier to store when travelling away from home.

The label change has been recently agreed in the European Union and is planned to be rolled out to other territories and countries.

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 one in 4,000 and one in 10,000.
Non childhood related adult growth hormone deficiency can also be a significant problem which affects
three in 10,000 each year. It is recognized as a specific clinical syndrome.
