Current status of biosimilars in Turkey: A survey among medical oncologists

INTRODUCTION

To evaluate biosimilar understanding and preference trends of medical oncologists in Turkey.

METHODS

A survey consisting of 24 multiple-choice questions with checkbox answers was conducted among medical oncologists. The questionnaire was divided into five parts to some intentions: demographic characteristics, general knowledge about biosimilars, knowledge about local approval and reimbursement issues, individual preference trends, and ranking the knowledge of their own. All answers were analyzed as whole cohort, specialists and fellows.

RESULTS

Fellows (n = 47) consisted 42%, and academic clinicians (n = 37) consisted 35% of the participants. In the whole cohort, the overall rate of correct answers was 55.1% in the general knowledge about the biosimilars part, and 26.7% in the local approval and reimbursement issues part. At all, 57.7% of the participants declared that they object to switch from a reference product to a biosimilar product. The rate of those who defined themselves as extremely knowledgeable decreased from 8.1% to 2.7% in the whole cohort at the end of the survey.

CONCLUSION

The need for more accurate and clarified local regulations and education emerging in the biotechnology era must be met.

Biosimilars in oncology: Effects on economy and therapeutic innovations

AIM

The introduction of new and innovative treatment options for cancer patients is accompanied by a tremendous increase in healthcare costs. Consequently, new financing approaches are strongly needed to reduce the burden on the healthcare system. The introduction of biosimilars - biological drugs containing the active substance of an already approved reference biological drug - can potentially relieve the burden on healthcare systems. Calculating the costs for three frequently used biosimilars, we simulated the health-economic impact of biosimilars in the real world for the German healthcare system.

METHODS

Based on available health-economic analyses, the actual prescription and cost containment potential of biosimilars compared to the originator were calculated exemplarily for the cost-intensive therapies trastuzumab in breast cancer, rituximab in follicular lymphoma and G-CSF in supportive care. Incidence calculations were based e.g. on data from the Robert-Koch-Institution, Munich Cancer Registry, and quality indicators of certified centres. Cost calculation was based on Lauer-Taxe® (official reference for pharmaceutical price information).

RESULTS

The application of biosimilars would generate potential annual savings for the chosen examples of up to 4.9 Mio EUR for rituximab in follicular lymphoma, 40.5 Mio EUR for filgrastim, 56.4 Mio EUR for pegfilgrastim, and between 95.9 and 120.5 Mio EUR for trastuzumab.

CONCLUSIONS

The consequent use of biosimilars allows a considerable reduction of overall treatment costs, especially for cost-intensive long-term maintenance treatments and therapies with high incidences. If the option of biosimilar usage is fully exploited, enormous resources could be released within the healthcare system in order to offset financing new innovative therapies.
