Pregnancy category
D Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.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

Reblozyl luspatercept was approved for the following therapeutic use:

Reblozyl is indicated for the treatment of adult patients with transfusion-dependent anaemia (requiring 2 or more RBC units over 8 weeks) due to very low, low and intermediate-risk myelodysplastic syndromes with ring sideroblasts (MDS-RS).

Reblozyl is indicated for the treatment of adult patients with transfusion-dependent anaemia associated with beta thalassaemia.

Limitation of Use

Reblozyl is not indicated for use as a substitute for RBC transfusions in patients who require immediate correction of anaemia.

What is this medicine and how does it work
Luspatercept is a recombinant fusion protein consisting of a modified form of the extracellular domain of the human activin receptor type IIB (ActRIIB) linked to the human immunoglobin G1 (IgG1) fragment constant (Fc) domain. It acts as a ligand trap for select transforming growth factor beta (TGF-β) superfamily ligands. By binding to certain endogenous ligands that act as negative regulators of erythropoiesis, luspatercept inhibits downstream Smad2/3 signalling, resulting in erythroid maturation through differentiation of late-stage erythroid precursors (normoblasts) in the bone marrow. TGF-β superfamily signalling through Smad2/3 is abnormally high in disease models characterised by ineffective erythropoiesis, that is myelodysplastic syndromes (MDS) and β-thalassaemia, and in the bone marrow of MDS patients.
What post-market commitments will the sponsor undertake
  • Reblozyl (luspatercept) is to be included in the Black Triangle Scheme. The Product Information and Consumer Medicines Information for Reblozyl must include the black triangle symbol and mandatory accompanying text for 5 years, which starts from the date that the sponsor notifies the TGA of supply of the product.
  • The Reblozyl European Union-Risk Management Plan (RMP) (version 1.0, dated 12 May 2020, data lock point May 2018), with Australian Specific Annex (version 2.0, dated 14 December 2020), included with submission PM-2020-01706-1-6, 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 3 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 (Rev 1), Part VII.B Structures and processes. Note that submission of a PSUR does not constitute an application to vary the registration.
  • Laboratory testing & compliance with Certified Product Details
    i. All batches of 334510 Reblozyl (luspatercept) 25 mg powder for injection vial and 334511 Reblozyl (luspatercept) 75 mg powder for injection vial supplied in Australia must comply with the product details and specifications approved during evaluation and detailed in the Certified Product Details (CPD).
    ii. 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, as described in Guidance 7: Certified Product Details of the Australian Regulatory Guidelines for Prescription Medicines (ARGPM) (, in PDF format, for the above products should be provided upon registration of these therapeutic goods.
