Proposal for paliperidone depot injection, risperidone depot injection and olanzapine depot injection
PHARMAC is seeking feedback on a proposal to fund paliperidone depot injection (Invega Sustenna) from 1 May 2014 in conjunction with a price decrease on risperidone depot injection (Risperdal Consta), both through a provisional agreement with Janssen-Cilag Pty Ltd (Janssen).
Both treatments would be subject to community and hospital restrictions for patients with schizophrenia and related psychoses. Amendments to the community and hospital restrictions for risperidone depot injection and olanzapine depot injection (Zyprexa Relprevv) are also proposed, which would allow patients with an approvals for risperidone depot and olanzapine depot to access paliperidone depot without having to re-meet the initial approval criteria (and vice versa).

Chemical Presentation Brand Pack size Proposed price and subsidy Paliperidone Inj 25 mg syringe Invega Sustenna 1 $194.25 Paliperidone Inj 50 mg syringe Invega Sustenna 1 $271.95 Paliperidone Inj 75 mg syringe Invega Sustenna 1 $357.42 Paliperidone Inj 100 mg syringe Invega Sustenna 1 $435.12 Paliperidone Inj 150 mg syringe Invega Sustenna 1 $435.12 - A confidential rebate would apply to Invega Sustenna from 1 October 2017.
- Paliperidone depot injection would be listed in Section B of the Pharmaceutical Schedule subject to the following Special Authority restrictions:
Special Authority for Subsidy
Initial application from any relevant practitioner. Approvals valid for 6 months for applications meeting the following criteria:
Either:
- The patient has had an initial Special Authority approval for risperidone depot injection or olanzapine depot injection; or
- All of the following:
- The patient has schizophrenia or other psychotic disorder; and
- Has tried but failed to comply with treatment using oral atypical antipsychotic agents; and
- Has been admitted to hospital or treated in respite care, or intensive outpatient or home-based treatment for 30 days or more in last 12 months.
Renewal from any relevant practitioner. Approvals valid for 12 months for applications meeting the following criteria:
Either:

Note: Paliperidone depot injection should ideally be used as monotherapy (i.e. without concurrent use of any other antipsychotic medication). In some cases, it may be clinically appropriate to attempt to treat a patient with typical antipsychotic agents in depot injectable form before trialling paliperidone depot injection.

Background
Paliperidone is the major active metabolite of risperidone. The key difference between paliperidone depot injection and risperidone depot injection is that paliperidone depot can be given every four weeks (or monthly) and risperidone depot is given fortnightly.
This proposal arose from a funding application from Janssen for paliperidone depot. The funding application has been reviewed by the Pharmacology and Therapeutics Advisory Committee (PTAC) and the Mental Health Subcommittee of PTAC on a number of occasions, most recently by PTAC at its November 2013 meeting.
In summary, while noting that there were some potential advantages of paliperidone depot, PTAC recommended that paliperidone depot be funded only if it was cost-neutral to risperidone depot, on the basis that the available evidence suggests that the two treatments provide similar efficacy. Minutes of the PTAC and Mental Health Subcommittee reviews of paliperidone depot can be found on PHARMAC’s website at: https://connect.pharmac.govt.nz/apptracker/s/global-search/paliperidone%20depot(external link)
Please note that PHARMAC is not intending to progress a proposal to fund paliperidone tablets at this time, taking into account the advice received from PTAC and the price differential between paliperidone tablets and other funded oral antipsychotics.
