Practical steps 

Your local Pfizer representative/Healthcare Partnership Manager can provide you with guidance on how to initiate NGENLA for your patients. Access guidance on how to contact us here.

Consider NGENLA for:

Newly diagnosed paediatric Growth Hormone Deficiency (pGHD) patients

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). The recommended dose is 0.66 mg/kg body weight administered once weekly by subcutaneous injection.​​​​​​​1​​​​

Current pGHD patients who are currently on daily GH

Consider NGENLA for your pGHD patients aged 3 years or older who are currently on daily GH treatment, and may benefit from once-weekly treatment. These may include:

• Patients who prefer a less frequent injection schedule
• Patients currently on a daily GH, who are transitioning to injecting themselves.

For patients switching from daily growth hormone, therapy with NGENLA may be initiated at a dose of 0.66mg/kg/week on the day following their last daily growth hormone injection.​​​​​​​1

Once-weekly NGENLA may deliver a treatment experience favoured by patients and caregivers​​​​​​​2

NGENLA delivered a favoured treatment experience for patients and caregivers in a phase 3 crossover study versus daily Genotropin (somatropin) in pGHD, based on lower treatment burden as shown by less life interference, using a range of parameters.

Life interference parameter overall mean scores where patients and caregivers favoured once weekly NGENLA (95% CI) after 12 weeks vs. once daily Genotropin included: willingness to continue treatment, impact on daily activities, caregiver & family life interference and convenience & ease of the injection schedule.

Study Design

Patients and caregivers (N=87) reported improved (lower) Life Interference total score after 12 weeks of once-weekly NGENLA treatment compared to once-daily GH.1,2 Phase 3, randomised, open-label, 2-period, crossover, multicentre study assessing patient perception of treatment burden with the use of NGENLA once weekly versus Genotropin once daily in children 3 to <18 years of age with GH deficiency.1,2
Data are based on patient/caregiver recall following each 12-week treatment period and at the end of the study. Caregivers completed the assessment for children under 8 years of age.2
† Based on Patient Global Impression Severity-Impact on Daily Activities.​​​​​​​2
