Somavert is used in the treatment of adult patients with acromegaly who have had an inadequate response to surgery and/or radiation therapy and in whom an appropriate medical treatment with somatostatin analogues did not normalise IGF-I concentrations or was not tolerated.


Somavert normalises IGF-1 in a unique way1

Somavert mechanism of action

Somavert works on cell surfaces around the body, directly targeting and blocking growth hormone receptors to inhibit IGF-I production with a high predictibility1-3

Somavert can help achieve high rates of IGF-I normalisation1,3

Somavert IGF-I normalisation rates at 12 weeks and 12 months

Somavert’s tumour-independent mechanism of action may explain how it can achieve IGF-I normalisation notes of up to 97% when appropriately titrated (n=90, p<0.05)3

p=0.02 **p<0.001. Maximum recommended dose of Somavert should not exceed 30mg daily1 

Somavert seeks to minimise the impact of acromegaly on quality of life

Somavert symptom score reductions at 6 months

Patients on Somavert report significant reductions versus baseline in soft tissue swelling, headache, joint pain and general physical condition, and total signs and symptoms score‡1,5

Total signs and symptoms score reduction observed at 12 weeks (p<0.05, n=112).
