Dosage

Sunlenca should be prescribed by physicians experienced in the treatment of human immunodeficiency virus (HIV). Prior to starting Sunlenca, the healthcare professional should carefully select patients who agree to the required injection schedule.

To help maintain viral suppression and reduce the risk of viral rebound and potential development of resistance associated with missed doses, the healthcare professional should also counsel patients about the importance of adherence to both the scheduled dosing visits and the optimised background regimen.

The recommended Sunlenca treatment regimen in adults consists of an initiation dosing period (oral tablets and subcutaneous injections) and once every 6-months maintenance dosing (subcutaneous injections). Sunlenca oral tablets may be taken with or without food.

If Sunlenca is discontinued, it is essential to adopt an alternative, fully suppressive antiretroviral regimen where possible, no later than 28 weeks after the final injection of Sunlenca.

For further information refer to the Product Information.

Pregnancy category
B1
Drugs 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

Sunlenca (lenacapavir sodium) was approved for the following therapeutic use:

Sunlenca, in combination with other antiretrovirals, is indicated for the treatment of adults with multidrug resistant HIV-1 infection for whom it is otherwise not possible to construct a suppressive anti-viral regimen.

What is this medicine and how does it work
Lenacapavir is a multistage, selective inhibitor of human immunodeficiency virus-1 (HIV-1) capsid function that directly binds to the interface between capsid protein (CA) subunits. Lenacapavir inhibits HIV-1 replication by interfering with multiple, essential steps of the viral lifecycle, including capsid-mediated nuclear uptake of HIV-1 proviral DNA (by blocking nuclear import proteins binding to capsid), virus assembly (by interfering with Gag/Gag-Pol functioning, reducing production of CA subunits), and capsid core formation (by disrupting the rate of capsid subunit association, leading to virions with malformed capsids and reduced infectivity).
Lenacapavir has activity that is specific to human immunodeficiency virus (HIV-1 and HIV-2).
What post-market commitments will the sponsor undertake
  • Sunlenca (lenacapavir sodium) is to be included in the Black Triangle Scheme. The PI [Product Information] and CMI [Consumer Medicine Information] for Sunlenca 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 Sunlenca EU [European Union]-risk management plan (RMP) (version 0.1, dated 19 July 2021, data lock point 1 April 2021), with Australia specific annex (version 0.2, dated June 2022), included with Submission PM-2022-00982-1-2, 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.

  • The final clinical study report (CSR) for Study GS-US-200-4625 (CAPELLA) should be submitted to the TGA, once available.
  • The final clinical study report (CSR) for Study GS-US-200-4334 (CALIBRATE) should be submitted to the TGA, once available.
  • For all injectable products the Product Information must be included with the product as a package insert.
