Evaluation of Nurse Preferences Between the Lanreotide Autogel New Syringe and the Octreotide Long-Acting Release Syringe: An International Simulated-Use Study (PRESTO).

ABSTRACT:

Introduction

Somatostatin analogues are used to treat symptoms and slow tumour progression in patients with neuroendocrine tumours (NETs) and carcinoid syndrome and to reduce hormone secretion and pituitary tumour volume in patients with acromegaly. A new syringe for lanreotide autogel/depot (LAN) was developed following feedback from a human factors study to improve ease of injection compared with previous syringes. PRESTO aimed to assess preferences of nurses between the LAN new syringe and the octreotide long-acting release (LAR) syringe.

Methods

PRESTO, a multinational, multicentre, prospective, noninterventional, simulated-use study, enrolled nurses with ≥ 2 years' experience injecting LAN and/or octreotide LAR in patients with NETs and/or acromegaly. Nurses administered injections into pads using the LAN new syringe and octreotide LAR syringe in a randomised sequence. In an anonymous web-based questionnaire, nurses reported their overall preference ('strong' or 'slight'; primary endpoint) and rated and ranked the importance of nine attributes for each syringe (1 [not at all] to 5 [very much]).

Results

Overall, 90 nurses attended sessions and completed valid questionnaires. Most nurses (97.8%) expressed a preference (85.6% 'strong', 12.2% 'slight') for the LAN new syringe versus the octreotide LAR syringe (P < 0.0001). Attribute performance ratings (1 [not at all] to 5 [very much]) were consistently higher for the LAN new syringe versus the octreotide LAR syringe, with the greatest differences in 'fast administration' and 'confidence the syringe will not be clogged' (mean difference [SD]: 2.6 [1.2] and 2.3 [1.5], respectively; P < 0.0001). The attribute ranked most important was 'confidence the syringe will not be clogged' (24.4%); least important was 'convenience of syringe format, including packaging, from preparation to injection' (34.4%).

Conclusions

Nurses preferred the user experience of the LAN new syringe compared with the octreotide LAR syringe, with a particular preference for attributes related to product delivery with the LAN new syringe.

Project description:INTRODUCTION:Although the previous lanreotide autogel/depot syringe had been well received, feedback indicated that improvements could be made to make it more user-friendly. Additionally, the view that patients should have greater involvement in the research and development process is echoed by the International Neuroendocrine Cancer Alliance. A series of studies aimed to develop and validate a new syringe that works better for patients, caregivers and healthcare professionals (HCPs) by involving these groups at key stages in the development and testing process. METHODS:The multicentre, international, human factor studies, consisted of four formative studies and one validation study. The formative studies collected patient, caregiver and HCP feedback on the lanreotide autogel/depot syringe on the market at the time, and on newly designed prototypes. The validation study was conducted to evaluate the final syringe to confirm that it can be used effectively and safely in the intended environment, by the intended user, for the intended purpose. RESULTS:Overall, 213 individuals participated in the studies; 145 contributed to the formative studies and 68 to the validation study. The validated new-generation syringe included several important updates compared with the lanreotide autogel/depot syringe currently on the market, including the flanges, which are now larger and have a better grip; the overcap, which is white, ridged, opaque and bigger; the plunger supports and the thermoformed tray. No participant hurt themselves or others during the validation study (although several misuses were reported), and all participants succeeded in delivering a complete dose and activating the safety system. CONCLUSION:With collaboration, a new syringe was developed to meet the needs of patients, caregivers and HCPs, whilst ensuring lanreotide was delivered effectively and safely. These studies highlight the importance of involving patients, caregivers and HCPs in clinical evaluation studies to develop medical products that address their concerns and meet their needs.
