What is NGENLA?

NGENLA is indicated for the treatment of children and adolescents from 3 years of age with growth disturbance due to insufficient secretion of growth hormone (GH). NGENLA is a long-acting GH with once-weekly dosing and may deliver a preferred treatment experience vs daily Genotropin. NGENLA is available with Pfizer-funded patient support and has a comparable cost to other daily GH options.​​​​​​​1,2,3

Pfizer has been dedicated to supporting children with GH disorders, including paediatric GH deficiency, to achieve their growth potential for over 30 years.4

NGENLA administered once-weekly demonstrated significant reduction in treatment burden, greater patient convenience, greater intent to comply and greater patient preference compared with daily Genotropin (somatropin).​​​​​​​1,2

Pfizer can support you in initiating your patients on NGENLA, whilst patients and caregivers can have peace of mind that they can continue to access Pfizer’s patient support programme.

Mode of Action

Once-weekly dosing with NGENLA is achieved with C-Terminal Peptide (CTP) technology, extending the half-life of human Growth Hormone (hGH).

Somatrogon is composed of a human Growth Hormone molecule fused with C-terminal peptide (CTP) from naturally occurring human chorionic gonadotropin (hCG).1,5

• C-terminal peptides are naturally occurring peptides derived from the beta chain of hCG.5

• C-terminal peptides provide hCG with required longevity, but do not impact interaction with hCG and its receptor.5

• Like hGH, somatrogon binds to the GH receptor and initiates a cascade leading to changes in growth and metabolism.1
