PBAC outcome
5.1 The PBAC recommended that the current listing for the 25 mg strength quetiapine tablets be changed to allow for up to 5 repeats via an Authority Required prescription for maintenance therapy for treatment of acute mania, bipolar 1 disorder and in the treatment of schizophrenia.PSD · Jul 2018
5.2 The PBAC considered that this could be achieved by removing the note “No increase in the maximum number of repeats may be authorised” in the Administrative Advice and removal of “The treatment must be for dose titration purposes” from the clinical criteria.PSD · Jul 2018
Comparative effectiveness
The key results of the two trials (Study 144 and Tohen 2006) incorporated in the submission’s indirect comparison of quetiapine and olanzapine in time to recurrence of a mood event using interim intention to treat (ITT) population (patients for whom data was collected up to the interim stop date) and intention to treat (ITT) population (all randomised patients who received treatment) were as follows: Study 144 reported a significant advantage in time to …PSD · Jul 2010
The PBAC noted that there were three issues which reduced the comparability of the two trials used in the indirect comparison: 1. Structure of the trial. Both trials incorporated an open-label treatment stabilisation phase before the patients were randomised for the double-blind monotherapy maintenance treatment. Both trials saw a substantial number of withdrawals between enrolment and randomisation.PSD · Jul 2010

Cost-effectiveness

Not modelled — this is a minor administrative submission concerning repeats for an existing listing, not a new clinical or economic evaluation.

The PBAC considered that the submission’s claim that quetiapine XR augmentation is superior in terms of efficacy over lithium augmentation was inadequately supported by the evidence presented. In terms of safety, the PBAC observed the occurrence of specific adverse events was different between the two treatment arms. Given the differences in the adverse event profiles of the two drugs, the PBAC did not accept the submission’s claim that quetiapine XR augmentation was equivalent in terms of comparative safety to lithium augmentation.

Decision context

PopulationPatients with schizophrenia, acute mania associated with bipolar I disorder, or bipolar I disorder requiring maintenance therapy at doses not adequately provided by other strengths of quetiapine (e.g. 37.5 mg or 52.5 mg).
