Adalimumab: What we’re proposing for rheumatological conditions

We want to hear from people on a proposal that would give more New Zealanders funded access to adalimumab.

On this page

We are seeking feedback on a proposal to make changes to the funded brand of adalimumab, from Humira to a citrate-free biosimilar adalimumab called Amgevita from 1 February 2022 through a provisional agreement with Amgen (New Zealand) Limited. Adalimumab is a biologic medicine used to treat a range of rheumatology, gastrointestinal, dermatological, and other autoimmune conditions. 

Adalimumab is currently funded for a range of rheumatological indications, subject to Special Authority criteria(external link), those associated with rheumatological conditions include: 

  • Adult-onset Stills disease
  • Ankylosing spondylitis
  • Juvenile idiopathic arthritis (oligoarticular and polyarticular)
  • Psoriatic arthritis
  • Rheumatoid arthritis 

If the proposal is approved a number of changes would occur from 1 February 2022. This would include awarding Principal Supply Status to a biosimilar adalimumab product (Amgevita) and widening access to this treatment for a number of rheumatological conditions. 

A summary of the changes includes: 

  • A biosimilar adalimumab (Amgevita, supplied by Amgen) would be funded from 1 February 2022 
  • All people who start on adalimumab treatment after 1 February 2022 would receive Amgevita 
  • People who are receiving treatment with the currently listed brand of adalimumab (Humira) before 1 February 2022 would need to be considered for a move to Amgevita before 31 August 2022 
  • We understand there may be some people who need to move back Humira if Amgevita is unable to be tolerated by a current patient, after a trial. Humira would remain listed for these circumstances, subject to funding criteria for these people following consultation with their prescriber 

Feedback on this consultation will help us to understand if any changes should be made to this proposal. Consultation closes at 5 pm on Wednesday, 22 September 2021. Feedback can be emailed to consult@pharmac.govt.nz

Widening access for rheumatological conditions

Changing to a biosimilar adalimumab means that more New Zealanders would be able to access adalimumab.

As part of the proposal to award Principal Supply Status, Pharmac is proposing to widen access to Amgevita for a range of uses, including a number for rheumatological conditions. 

More information on each application, including relevant clinical advice records, can be found through below links to the Application Tracker: 

 We estimate that approximately 245 people would benefit in the first year of funding as a result of these changes in access to adalimumab for rheumatological conditions.

These proposed changes in access reflect funding requests that have been made to Pharmac and have previously been considered for Pharmaceutical Schedule listing. The proposed price reduction of adalimumab (Amgevita) means we are able to prioritise these applications for funding now.  

Undifferentiated spondyloarthritis

Pharmac received a funding application to widen access to adalimumab to treat undifferentiated spondyloarthritis in December 2013. This application has been reviewed by both PTAC and the Rheumatology Subcommittee. In February 2015 [PDF, 498 KB] PTAC recommended funding for this patient population with a medium priority. More information about this funding application, including links to the relevant clinical advice records, can be found in the Application Tracker(external link).

Etanercept (a biologic treatment) has been funded for undifferentiated spondyloarthritis since 1 March 2020. This proposal would mean that from 1 February 2022, people with undifferentiated spondyloarthritis would have access to another biologic treatment which can be administered at home or in the community. We estimate that approximately 55 patients would benefit from this proposal in the first year of funding. 

The criteria for funded access to adalimumab (Amgevita) would be amended in Section B and Part II of Section H of the Pharmaceutical Schedule from 1 February 2022 to include people with undifferentiated spondyloarthritis (proposed new criteria shown only):

ADALIMUMAB (AMGEVITA)

Initial application — (undifferentiated spondyloarthritis) only from a rheumatologist. Approvals valid for 6 months for applications meeting the following criteria:

All of the following:

Note: Indications marked with * are unapproved indications 

ADALIMUMAB (AMGEVITA)

Renewal — (undifferentiated spondyloarthritis) from any relevant practitioner. Approvals valid for 2 years for applications meeting the following criteria:

Either:

  1. Following initial treatment, the patient has at least a 50% decrease in active joint count from baseline and a clinically significant response to treatment in the opinion of the physician; or
  2. The patient demonstrates at least a continuing 30% improvement in active joint count from baseline and a clinically significant response in the opinion of the treating physician.

The application(external link)for adalimumab for the treatment of undifferentiated spondyloarthritis in the second line(external link) (after etanercept) would be superseded by this proposal and would therefore be removed from further consideration. 

Inflammatory bowel disease associated arthritis (IBD-A)

Pharmac received a funding application to widen access to adalimumab to treat inflammatory bowel disease associated arthritis in December 2013. This application has been reviewed by PTAC and the Rheumatology Subcommittee of PTAC several times. In February 2015 [PDF, 498 KB] PTAC recommended funding for this patient population with a medium priority. More information on this application, including links to the relevant clinical advice records, can be found in the Application Tracker(external link).

This proposal would mean that from 1 February 2022, people with inflammatory bowel disease associated arthritis would have access to a biologic treatment which can be administered at home or in the community. We estimate that about 60 people would benefit from this proposal in the first year of funding. 

The criteria for funded access to adalimumab (Amgevita) would be amended in Section B and Part II of Section H of the Pharmaceutical Schedule from 1 February 2022 to include people with inflammatory bowel disease associated arthritis (IBD-A) (proposed new criteria shown only):

Inflammatory bowel arthritis – axial

ADALIMUMAB (AMGEVITA)

Initial application — (inflammatory bowel arthritis – axial) only from a rheumatologist. Approvals valid for 6 months for applications meeting the following criteria:

All of the following

  1. Patient has a diagnosis of active ulcerative colitis or active Crohn’s disease; and
  2. Patient has axial inflammatory pain for six months or more; and
  3. Patient is unable to take NSAIDs; and
  4. Patient has bilateral sacroiliitis demonstrated by radiological imaging; and
  5. Patient has not responded adequately to prior treatment consisting of at least 3 months of an exercise regime supervised by a physiotherapist; and
  6. A BASDAI of at least 6 on a 0‑10 scale completed after the 3 month exercise trial, but prior to ceasing any previous pharmacological treatment 

ADALIMUMAB (AMGEVITA)

Renewal — (inflammatory bowel arthritis – axial)

Approvals from any relevant Practitioner. Approvals valid for 2 years for applications where treatment has resulted in an improvement in BASDAI of 4 or more points from pre-treatment baseline on a 10 point scale, or an improvement in BASDAI of 50%, whichever is less.

Inflammatory bowel arthritis – peripheral

ADALIMUMAB (AMGEVITA)

Initial application — (inflammatory bowel arthritis – peripheral) only from a rheumatologist. Approvals valid for 6 months for applications meeting the following criteria:

Both:

ADALIMUMAB (AMGEVITA)

Renewal — (inflammatory bowel arthritis – peripheral) Approvals from any relevant practitioner. Approvals valid for 2 years for applications where:

Either:

  1. Following initial treatment, patient has at least a 50% decrease in active joint count from baseline and a clinically significant response to treatment in the opinion of the physician; or
  2. Patient demonstrates at least a continuing 30% improvement in active joint count from baseline in the opinion of the treating physician.

The application(external link) for use of infliximab as a treatment of inflammatory bowel disease associated arthritis (IBD-A) disease remains under consideration by Pharmac.

Rheumatoid arthritis – Special authority changes to joint count and CRP levels

Pharmac received a funding application to widen access to adalimumab for the treatment of rheumatoid arthritis in November 2019. The funding application requested the following changes to be made to the Special Authority for adalimumab:

  • Reduce the required number of active joints for access to adalimumab and etanercept from 20 to 15
  • Remove the requirement for a C-reactive protein (CRP) level to be greater than 15 mg/L

The Rheumatology Subcommittee reviewed this application in May 2021 [PDF, 184 KB] and recommended changes be made to the access criteria of both adalimumab and etanercept (as first line biologic treatments for rheumatoid arthritis patients) with a high priority. More information on this funding application, including links to the relevant clinical advice records, can be found in the Application Tracker.(external link)

This proposal would mean that, from 1 February 2022 more people with rheumatoid arthritis would have access to adalimumab or etanercept treatment. We estimate that approximately 130 additional patients would benefit from this proposal in the first year of funding. 

The criteria for funded access to adalimumab (Amgevita), and etanercept (Enbrel) would be amended in Section B and Part II of Section H of the Pharmaceutical Schedule from 1 February 2022:

Amendments to Special Authority criteria provides further information on all Special Authority changes.

ADALIMUMAB (AMGEVITA) / ETANERCEPT

Initial application — (rheumatoid aArthritis - rheumatoid) only from a rheumatologist. Approvals valid for 6 months for applications meeting the following criteria:

Either:

ADALIMUMAB (AMGEVITA) / ETANERCEPT

Renewal — (rheumatoid aArthritis - rheumatoid)  from any relevant practitioner only from a rheumatologist or Practitioner on the recommendation of a rheumatologist.

Approvals valid for 2 years 6 months for applications meeting the following criteria:
All of the following:

Note, the removal of dosing restrictions for patients with Rheumatoid Arthritis is specific to Amgevita and has not been assessed for etanercept (Enbrel).

The application(external link) requesting a reduction in the number of prior immunosuppressant agents (disease modifying anti-rheumatic drugs – DMARDs) that must be trialled prior to funded access to adalimumab and/or etanercept remains under consideration by Pharmac.

Amendments to Special Authority criteria for rheumatological conditions

We are also proposing changes to the adalimumab (Amgevita) Special Authority criteria for currently funded indications to improve access to adalimumab treatment.

This would include:

  • Special Authority renewal periods would be extended from 6 months to 2 years
  • Special Authority renewals could be applied for by any relevant practitioner
  • There would be no dosing restrictions for people using Amgevita
  • Removal of renewal criteria for Adult-Onset Still Disease to enable approval without renewal

These changes would be made to the current access criteria for patients from 1 February 2022. They would be specific to the Amgevita brand of adalimumab. The changes relating to specific rheumatological conditions are detailed below(additions in bold, deletions in strikethrough).

To dispense and claim a subsidy, the correct brand would need to be prescribed for each patient. Special Authority approvals would not be interchangeable. 

Note, where adalimumab criteria are interchangeable with other biologic treatments (such as etanercept or infliximab), Pharmac would assess changes to these following a decision on adalimumab to ensure ongoing alignment of access criteria (excluding changes to Rheumatoid Arthritis detailed above).

Alternative brand access from 1 September 2022 for rheumatological conditions

From 1 February 2022, patients receiving treatment with Humira would need to move to Amgevita. This change would be carefully managed by treating clinicians, working closely with primary care, the patient, their family, whānau, and caregivers. 

Based on clinical advice received, we anticipate that most existing patients who take adalimumab would be able to change to the Amgevita brand of adalimumab. However, clinicians would be able access funded treatment with Humira via Special Authority for patients that do not tolerate treatment after a trial with Amgevita (if appropriate and safe to consider further treatment with adalimumab). 

Access to Humira after 31 August 2022 would be through new Special Authority criteria. These criteria would replace the current Special Authority access criteria from 1 September 2022, and a new Special Authority application would need to be made for these patients following discussion with their doctor.

Renewal criteria would remain consistent with criteria currently in place for Humira. No changes are proposed.

The criteria as they relate to rheumatological conditions are detailed below (new criteria shown only).
