The Brenzys autoinjector, an etanercept biosimilar, was significantly preferred for ease of use over Enbrel autoinjectors by rheumatoid arthritis patients and healthcare professionals. This study highlights improved usability for self-injection therapies.
Area of Science:
- Rheumatology
- Drug Delivery Systems
- Biosimilars
Background:
- Rheumatoid arthritis (RA) impacts manual dexterity, making autoinjector ease-of-use critical for long-term therapy.
- Brenzys is an etanercept biosimilar developed to offer an alternative to Enbrel for RA treatment.
Purpose of the Study:
- To compare patient and healthcare professional preference and perceived ease of use of the Brenzys autoinjector against Enbrel MYCLIC (Australia) and Enbrel SureClick (Canada) autoinjectors.
- To evaluate the usability of a new autoinjector device for self-administration of RA therapy.
Main Methods:
- 191 RA patients and 90 healthcare professionals used Brenzys and Enbrel autoinjectors after training.
- Participants completed questionnaires assessing ease of use and preference after simulated injections.
- Study conducted in Australia and Canada with counterbalanced device order.
Main Results:
- Significantly more patients (79%) found the Brenzys autoinjector easier to use than Enbrel (p < 0.001).
- Healthcare professionals also rated Brenzys as significantly easier to use (86%) and recommended it over Enbrel (83%) (p < 0.001).
- Of patients with prior Enbrel autoinjector experience, 94% preferred switching to Brenzys.
Conclusions:
- The Brenzys autoinjector demonstrated statistically significant superiority in ease of use and preference among both RA patients and experienced healthcare professionals.
- Results suggest the Brenzys autoinjector may enhance self-delivery of etanercept therapy for rheumatoid arthritis.
