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.
