Proposal to widen access to rituximab for people with B-cell acute lymphoblastic leukaemia/lymphoma
We are seeking feedback on a proposal to widen funded access to rituximab (Riximyo).
What we’re proposing
We are seeking feedback on a proposal to widen funded access to rituximab (Riximyo) for the treatment of people with newly diagnosed B-cell acute lymphoblastic leukaemia/lymphoma.
This funding is proposed to start from 1 August 2021.
Consultation closes at 4pm on Wednesday 9 June 2021 and feedback can be emailed to firstname.lastname@example.org.
What would the effect be?
This proposal would mean that from 1 August 2021, funded access to rituximab would be widened to include the treatment of people with newly diagnosed B-cell acute lymphoblastic leukaemia/lymphoma (B-cell ALL).
We estimate that approximately 20 patients would benefit from this proposal each year.
Who we think will be interested
- People with blood cancers and their whānau
- Haematologists and oncologists
- Hospital and community pharmacists
- Other organisations with an interest in the treatment of cancer
About rituximab and B-cell ALL
Rituximab is a monoclonal antibody agent currently funded for use in a variety of indications, including cancer, rheumatoid arthritis, autoimmune and haematological conditions (see: Section B(external link)).
Rituximab is Medsafe approved for the treatment of non-Hodgkin’s lymphoma, chronic lymphocytic leukaemia, rheumatoid arthritis, and granulomatosis.
Rituximab is not Medsafe approved for use in the other currently funded indications or for the proposed widening of funded access to include B-cell ALL.
B-cell ALL is an aggressive blood cancer that results in too many immature white blood cells in the bone marrow and blood. It is the most common type of acute lymphoblastic leukaemia (ALL). It is also called B-cell acute lymphocytic leukaemia and precursor B-lymphoblastic leukaemia.
Rituximab for the treatment of B-cell ALL is given intravenously, for a maximum of 18 doses in combination with chemotherapy. Our clinical advisors have indicated that there would be persistent long-term benefits when rituximab is added on to existing chemotherapy for people with B-cell ALL.
Why we’re proposing this
A funding application for rituximab for the treatment of newly diagnosed B-cell ALL(external link) was reviewed by PHARMAC’s Cancer Treatments Subcommittee of Pharmacology and Therapeutics Advisory Committee (PTAC) (CaTSoP) in August 2017 and in February 2021.
Rituximab (Riximyo) was awarded sole supply as part of a competitive procurement process in 2019 and was subsequently part of a successful biosimilar transition that concluded in 2020. As part of this process, the price and subsidy for rituximab reduced considerably and access was widened to rituximab for multiple cancers and inflammatory conditions, enabling treatment with rituximab for more New Zealanders.
In August 2017(external link), CaTSoP deferred making a recommendation for the funding of rituximab for people with newly diagnosed B-cell ALL due to uncertainty regarding the appropriate dosing regimen and the benefit of targeting funding to a subpopulation of patients.
Recently, at its February 2021 meeting(external link), CaTSoP recommended that rituximab be funded for the treatment of CD20 positive B-cell ALL with a medium priority and for the wider group of patients with B-cell ALL irrespective of CD20 expression with a low priority, subject to eligibility criteria.
We are proposing to fund rituximab for the wider group of patients (B-cell ALL irrespective of CD20 expression). The evidence indicates that the benefit of the proposed dosing regimen may be generalisable to all patients with B-cell ALL and not just those patients with CD20 expression.
Details about our proposal
The criteria for funded access to rituximab (Riximyo) would be amended in Section B and Part II of Section H of the Pharmaceutical Schedule from 1 August 2021 to include people with B-cell ALL (proposed new criteria shown only):
Special Authority for Subsidy
Initial application - (B-cell acute lymphoblastic leukaemia/lymphoma*) only from a relevant specialist or medical practitioner on the recommendation of a relevant specialist. Approvals valid for 2 years for applications meeting the following criteria:
All of the following:
- Patient has newly diagnosed B-cell acute lymphoblastic leukaemia/lymphoma; and
- Treatment must be in combination with an intensive chemotherapy protocol with curative intent; and
- The total rituximab dose would not exceed the equivalent of 375 mg/m2 per dose for a maximum of 18 doses.
Note: Indications marked with * are unapproved indications.
There are no proposed changes to other existing Special Authority criteria or hospital restrictions for rituximab.
