E057 International survey to evaluate current options and user needs for subcutaneous injection of methotrexate to inform development of a new injection device

Abstract

Abstract Background/Aims Prefilled syringes (PFS) and various types of pens are available for subcutaneous injection of methotrexate (MTX) in patients with rheumatoid arthritis or moderate to severe psoriasis. To assess the needs of users and the relevance of features of a new MTX autoinjector succeeding the metoject®/metex® PEN, an international online survey was performed. Methods A structured questionnaire was distributed to physicians, nurses and patients in Germany, France, and the United Kingdom. Participants received illustrations of the three MTX devices currently available on the market and were informed about the new MTX autoinjector. Results In total, 189 rheumatologists, 111 dermatologists, 90 nurses, and 180 patients answered the questions. Specific reasons for a preference for the use of MTX pens over PFS could predominantly be assigned to the categories “dosing/administration” and “ease of use”. 82% of physicians, 87% of nurses, and 76% of patients stated a positive first impression of the new button-free MTX autoinjector, respectively. The features rated most relevant by the user groups were a) 2-step autoinjector mechanism (receiving a mean 14.1 to 18.1 points of a total of 100 points), b) small injection volume (9.7 to 11.7 points), c) short injection time below 5 seconds (8.5 to 11.1 points), and d) 10 different doses for dose flexibility (8.0 to 13.2 points). Conclusion Autoinjectors for MTX appear to be preferred over PFS in this international survey. In addition, important features of MTX autoinjectors for patients and healthcare professionals were identified including the autoinjector mechanism, volume of injection and injection time.
