Dosage
Somapacitan should be initiated and monitored by physicians who are appropriately qualified and experienced in the diagnosis and management of adult patients with growth hormone deficiency (for example, endocrinologists).
Dosage is based on multiple factors, including the age of the patient and whether the patient has been switched from daily growth hormone medicinal products. The somapacitan dose must be individually adjusted for each patient.
For further information refer to the Product Information.
Pregnancy category
B1Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed.Studies in animals have not shown evidence of an increased occurrence of fetal damage.The use of any medicine during pregnancy requires careful consideration of both risks and benefits by the treating health professional. This must not be used as the sole basis of decision making in the use of medicines during pregnancy. The TGA does not provide advice on the use of medicines in pregnancy for specific cases. More information is available from obstetric drug information services in your State or Territory.
What was approved
Sogroya (somapacitan) was approved for the following therapeutic use:
Sogroya is indicated for the replacement of endogenous growth hormone (GH) in adults with growth hormone deficiency (AGHD).
What is this medicine and how does it work
Somapacitan is a long‑acting recombinant human growth hormone derivative. It consists of 191 amino acids similar to endogenous human growth hormone, with a single substitution in the amino acid backbone (L101C) to which an albumin binding moiety has been attached. The albumin binding moiety (side‑chain) consists of a fatty acid moiety and a hydrophilic spacer attached to position 101 of the protein.The mechanism of action of somapacitan is either directly via the growth hormone (GH)‑receptor and/or indirectly via insulin like growth factor‑1 (IGF-I) produced in tissues throughout the body, but predominantly by the liver. When growth hormone deficiency is treated with somapacitan, a normalisation of body composition (that is, decreased body fat mass, increased lean body mass) and of metabolic action is achieved.
What post-market commitments will the sponsor undertake
- Sogroya (somapacitan) is to be included in the Black Triangle Scheme. The Product Information (PI) and Consumer Medicines Information (CMI) for Sogroya must include the black triangle symbol and mandatory accompanying text for five years, which starts from the date that the sponsor notifies the TGA of supply of the product.
- The Sogroya European Union (EU)‑risk management plan (RMP) (version 1.0, dated 7 April 2021, data lock point 31 March 2019), with Australian specific annex (version 0.3, dated 20 December 2021), included with Submission PM‑2021‑01699‑1‑5, and any subsequent revisions, as agreed with the TGA will be implemented in Australia.
An obligatory component of risk management plans is routine pharmacovigilance. Routine pharmacovigilance includes the submission of periodic safety update reports (PSURs).
Reports are to be provided in line with the current published list of EU reference dates and frequency of submission of PSURs until the period covered by such reports is not less than three years from the date of the approval letter.
The reports are to at least meet the requirements for PSURs as described in the European Medicines Agency's guideline on Good Pharmacovigilance Practices (GVP) Module VII-periodic safety update report (revision 1), Part VII.B Structures and processes. Note that submission of a PSUR does not constitute an application to vary the registration.
Quality
- Laboratory testing and compliance with Certified Product Details (CPD)
- All batches of Sogroya (somapacitan) 6.7 mg/mL solution for injection prefilled pen supplied in Australia must comply with the product details and specifications approved during evaluation and detailed in the Certified Product Details (CPD).
- When requested by the TGA, the sponsor should be prepared to provide product samples, specified reference materials and documentary evidence to enable the TGA to conduct laboratory testing on the product. Outcomes of laboratory testing are published biannually in the TGA database of laboratory testing results and periodically in testing reports on the TGA website.
Certified Product Details
- The Certified Product Details (CPD), as described in Guidance 7: Certified Product Details of the Australian Regulatory Guidelines for Prescription Medicines (ARGPM), in portable document format (PDF), for the above products should be provided upon registration of these therapeutic goods. In addition, an updated CPD should be provided when changes to finished product specifications and test methods are approved in a Category 3 application or notified through a self-assessable change.
