Despite their availability for over a decade, the exact nature of biosimilar medicines is still poorly understood with paucity of clear treatment guidelines for their use in clinical practice in Australia. Although hematologists have had experience with biosimilars in the setting of supportive care, with the approval of the first biosimilar rituximab in hematological malignancies, it is important to revisit this topic. To inform the use of biosimilar medicines in clinical practice, we have developed a consensus statement from an Expert Panel of Australian hematologists, oncologists, and cancer pharmacists. These recommendations address the approach to use of biosimilar products in place of the corresponding reference medicine in a number of different clinical contexts. Our recommendations are based on the premise that biosimilar medicines can be considered therapeutically equivalent to their reference brand and used in a similar way to the reference product in any approved indication. We advocate for local approaches to the provision of patient information, dispensing of the intended brand and pharmacovigilance, to be developed in consultation with local hematologists and aim to improve confidence in the appropriate use of biosimilar medicines and their expected outcomes among hematologists.

A 14-year retrospective analysis of indications and outcomes of autologous haemopoietic stem cell transplantation in regional Queensland: a single-centre experience.

Intern Med J 2020 02;50(2):214-221

Icon Group, Brisbane, Queensland, Australia.

Background: The Townsville Hospital is a tertiary hospital in North Queensland with one of the largest regional transplant centres in Australia, performing primarily autologous haemopoietic stem cell transplants (HSCT) for various haematological malignancies.

Aims: This single-centre, retrospective, observational study aims to describe the activity and outcomes of autologous HSCT at The Townsville Hospital between 2003 and 2017 to verify safety standards.

Methods: Patient-level data were collected, including demographics, frequency and indication for transplant, conditioning, current clinical status and cause of death. Key outcomes included overall survival, non-relapse mortality, incidence of therapy-related neoplasm and causes of death. Progression-free survival in the multiple myeloma (MM) subgroup was also assessed.

Results: There were 319 autologous HSCT in 286 patients, with a median age of 58 years (range 14-71 years); 62% of patients were male. Indications for transplantation were: MM 53.7%, non-Hodgkin lymphoma 29.4%, Hodgkin lymphoma 5.0% and other 11.9%. Causes of death were: disease progression/relapse (65.2%), second malignancy (17.0%), infection (9.8%) and other (8.0%). Non-relapse mortality was 1.2% (95% confidence interval 0.4-3.0) and 3.2% (1.7-5.7) at 100 days and 1 year, respectively, post-HSCT. Overall survival at 2 years was 81.0% (73.8-86.4) for MM and 69.6% (58.8-78.1) for non-Hodgkin lymphoma. The median progression-free survival in the MM cohort was 3.3 years.

Conclusion: The Townsville Hospital transplant centre provides an important transplant service in regional Queensland, with outcomes comparable to national data. We reported a relatively high rate of second malignancy as a cause of death.
