Tocilizumab shortage: clinical management advice
The TGA, Australian Rheumatology Association (ARA) and Arthritis Australia have issued a joint statement for the clinical management of patients taking tocilizumab.
Noting that there are anticipated shortages across the different formulations at varying times until January 2022, the statement provides advice for managing patients with rheumatoid arthritis (RA), systemic juvenile idiopathic arthritis (sJIA), polyarticular juvenile idiopathic arthritis (pJIA), giant cell arteritis (GCA) and cytokine release syndrome (CRS).
It recommends prescribers review the shortage dates for each formulation and how that may affect their patients. Medication management strategies are presented for the different conditions and formulations.
Measures prescribers can take include reducing the frequency of tocilizumab SC dose where appropriate, delaying initiation of treatment when suitable alternatives are available and demonstrating how to use different subcutaneous presentations (pre-filled syringe and pre-filled pen autoinjector) in case patients need to be switched.
The statement also presents alternative biologic treatments for the affected conditions. However, for GCA there are no alternative biologics and it recommends tocilizumab be prioritised for these patients. And there are no PBS-listed biologic alternatives for sJIA patients.
For CRS patients on IV tocilizumab it recommends no change in treatment plan and that they be given the highest priority for tocilizumab over all other indications “due to the nature and urgency of the condition”.
