Interferon alfa-2a (Roferon-A) being discontinued
At the end of June 2020, Roche, the supplier of interferon alfa-2a (Roferon-A) stopped making this medicine globally. We understand that this change will affect about 25 people who currently take interferon alfa-2a.
PHARMAC's expert advice has confirmed that interferon alfa-2a is mainly used to treat:
- myeloproliferative disorders where patients can't take other funded alternatives (including patients who are pregnant or actively planning to become pregnant)
- T cell lymphomas, such as mycosis fungoides.
PHARMAC understands that interferon alfa-2a is no longer used to treat hepatitis C.
PHARMAC has widened access to pegylated interferon alfa-2a so that patients currently taking interferon alfa-2a can access an appropriate alternative. This took effect from 1 July 2020.
We understand that having to change medications can be frustrating. We apologise for any inconvenience.
Unfortunately the supplier (Roche) has stopped making interferon alfa-2a completely.
You will need to talk to your specialist about what alternative treatment is right for you.
Roche discontinued interferon alfa-2a (Roferon-A) globally, from the end of June 2020.
Potential alternative: Pegylated interferon alfa-2a
The Cancer Treatments Subcommittee of PTAC (CaTSoP) have given PHARMAC advice about this discontinuation.
CaTSoP advised that pegylated interferon alfa-2a would be an acceptable alternative to interferon alfa-2a for patients with:
- cutaneous T cell lymphoma, and
- myeloproliferative disorders (if other funded alternatives, such as hydroxyurea, anagrelide and busulfan are not appropriate).
We've widened the Special Authority criteria for pegylated interferon alfa-2a to help patients with these conditions to access the treatment. There are about 25 patients in New Zealand currently taking interferon alfa-2a.
Start transitioning patients
Current stock of interferon alfa-2a (Roferon-A) in the supply chain will likely be depleted before the end of 2020.
We ask that you start transitioning patients currently on interferon alfa-2a to alternative treatments.
At the end of June 2020, Roche discontinued interferon alfa-2a (Roferon-A, Pharmacode 483206).
PHARMAC has widened the access criteria for pegylated interferon alfa-2a (Pegasys, Pharmacode 2162806) to patients with myeloproliferative disorder and cutaneous T cell lymphoma. This took effect from 1 July 2020.
We're asking prescribers to transition their patients to an alternative treatment.
