Generalised myasthenia gravis

The PBS subsidises ravulizumab for patients with generalised myasthenia gravis (gMG).

Patient eligibility

The Pharmaceutical Benefits Scheme (PBS) subsidises treatment with ravulizumab under the National Health Act 1953, section 100 for patients with gMG.

Patients must be eligible for the PBS and meet the relevant restriction criteria.

The Schedule of Pharmaceutical Benefits on the PBS website outlines the restrictions for prescribing ravulizumab.

Section 100 arrangements

Ravulizumab

This item is only PBS-subsidised for non-admitted patients, day admitted patients or patients on discharge who are attending either:

  • an approved private hospital
  • a public hospital.

This item isn’t PBS-subsidised for public hospital in-patients.

You must include the hospital name and provider number on the authority application form.

Treatment specifics

To be eligible for PBS-subsidised treatment with ravulizumab, patients must be treated by a prescriber who is either a:

  • neurologist
  • clinical immunologist with expertise in the treatment of myasthenia gravis
  • medical practitioner in consultation with one of the above specialist types.

PBS-subsidised gMG treatment settings and time limits

Where the term ‘gMG biological agent’ is referenced, it refers to ravulizumab.

The following are settings and time limits where a gMG biological agent is PBS-subsidised:

  1. 3 months of acute treatment - ‘acute severe gMG’
  2. 6 months of bridging therapy - ‘bridging therapy for gMG’
  3. Continuous therapy - ‘treatment refractory gMG’.

A patient may transition sequentially from one phase to another where all criteria are met e.g. (1) to (2) to (3) but cannot return to an earlier treatment setting.

A NS-IST is one of the following:
