Applications completed on the database for originators

Table 4

Application type

Action

Initial

  • Create a patient record on the database if required
  • Create a new pended entry in the database
  • Send to a Pharmaceutical Advisor (PA) for assessment
  • Once application has been assessed by PA, complete the entry in the database

Grandfather

  • Create a patient record on the database if required
  • Create a new pended entry in the database
  • Send to a PA for assessment
  • Once application has been assessed by PA, complete the entry in the database

First continuing

If approved:

  • Create and complete an entry in the database
  • Enter the next assessment date (NAD)

Subsequent continuing

  • No line in the database required
  • If approved, enter the NAD

Change or Recommencement

  • Create a new pended entry in the database
  • Send to a PA for assessment
  • Once PA has assessed application, complete the entry in the database

Balance of supply

No database entry required.

Demonstration of response

  • Create and complete a new entry in the database
  • Update the drug history

Medical break

  • Create a new pended entry in the database
  • Send to a PA to action

Response to baselines

Table 5

Step

Action

1

Erythrocyte Sedimentation Rate (ESR)

Where ESR has been provided:

  • ESR must be either 25 or less, or reduced by 20% from the baseline level
  • The target level is found on the database
  • A response cannot be assessed against ESR if ESR is not recorded at baseline

2

C-Reactive Protein (CRP)

Where CRP has been provided:

  • CRP must be either 10 or less, or reduced by 20% from the baseline level
  • The target level is found on the database
  • A response cannot be assessed against CRP if CRP is not recorded at baseline

3

Response to Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

The BASDAI must be reduced by 2 compared to baseline:

  • Where the baseline is high (near 10) and the continuing is below 5, for example - a detailed measurement is not needed
  • If the current BASDAI does not appear greatly reduced, an accurate measurement is needed. Refer to a Pharmaceutical Advisor (PA)
  • If the patient is not responding on their BASDAI, the application must be rejected

Current treatment for subsequent continuing applications

Table 6

Step

Action

1

Is the previous next assessment date within 3 months of date of processing?

2

Is the application a subsequent continuing for a drug with a biosimilar brand listing?

3

Has the prescriber completed current treatment or supplied dates of most recent treatment course on the application form?

4

Check dispensing history. Is there a dispensing in the last 3 months?

5

Is there a letter or note from the prescriber regarding a break in treatment?

  • Yes, refer to a Pharmaceutical Advisor (PA)
  • No, Step reject

Exceptional criteria regarding blood markers

Table 7

Scenario

Action

1

A prescriber calls to say their patient is not meeting criteria based on their blood markers due to a medical or clinical reason

  • Check the patient's dispensing history. If there are repeats outstanding, tell the prescriber to reassess response after remaining treatment has been used by the patient
  • If no repeats are available, advise to complete a continuing application and document the reason for elevated bloods

2

Patient not meeting blood marker/s criteria and prescriber has included a medical or clinical reason in writing

  • Escalate to a Pharmaceutical Advisor (PA)

3

Approval decision

If:

  • approving request, only a one-month supply can be given
  • rejecting request, a rejection letter must be sent
