ABSTRACT
INTRODUCTION:
Real-world data evaluating patients' injection experiences using the latest devices/formulations of the long-acting (LA) somatostatin analogs (SSAs) lanreotide Autogel/Depot (LAN; Somatuline®) and octreotide LA release (OCT; Sandostatin®) are limited.METHODS:
PRESTO 2 was a 2020/2021 e-survey comparing injection experience of adults with neuroendocrine tumors (NETs) or acromegaly treated with LAN prefilled syringe versus OCT syringe for > 3 months in Canada, Ireland, the UK and the USA (planned sample size, 304). PRIMARY ENDPOINT the proportion of patients with injection-site pain lasting > 2 days after their most recent injection, analyzed using a multivariate logistic regression model. Secondary endpoints included interference with daily life due to injection-site pain and technical injection problems in patients with current SSA use for ≥ 6 months.RESULTS:
There were 304 respondents (acromegaly, n = 85; NETs, n = 219; LAN, n = 168; OCT, n = 136; 69.2% female; mean age, 59.6 years). Fewer patients had injection-site pain lasting > 2 days after the most recent injection with LAN (6.0%) than OCT (22.8%); the odds of pain lasting > 2 days were significantly lower for LAN than OCT, adjusted for disease subgroup and occurrence of injection-site reactions (odds ratio [95% confidence interval] 0.13 [0.06-0.30]; p < 0.0001). Injection-site pain interfered with daily life "a little bit" or "quite a bit" in 37.2% and 3.8% (LAN) versus 52.5% and 7.5% (OCT) of patients, respectively. Among patients with ≥ 6 months' experience with current SSA (92.4% of patients), technical injection problems never occurred in 76.8% (LAN) and 42.9% (OCT) of patients.CONCLUSIONS:
Compared with OCT, significantly fewer patients using LAN had injection-site pain lasting > 2 days after their most recent injection. Also, fewer LAN-treated patients experienced technical problems during injection. These findings demonstrate the importance of injection modality for overall LA SSA injection experience for patients with acromegaly or NETs.
Patients with neuroendocrine tumors or acromegaly often receive long-term monthly treatment with somatostatin analogs. These injectable drugs stop the body from making an excess of certain hormones. Understanding patients' experiences of these injections helps to provide better care. The PRESTO 2 online study surveyed 304 patients in Canada, Ireland, the UK and the USA with neuroendocrine tumors or acromegaly who were being treated with a somatostatin analog, either lanreotide Autogel/Depot (LAN) or octreotide long-acting release (OCT). The survey asked about injection experience, including injection-site pain lasting > 2 days and how it affected patients' lives, anxiety before injections and technical problems during injections (like syringe blockages). The survey showed fewer patients receiving LAN than OCT had injection-site pain that lasted > 2 days, and fewer said that the pain interfered with their daily lives. There were fewer technical injection problems with LAN than with OCT. However, more patients receiving LAN than OCT felt anxious before their injection. In some countries (including Canada, Ireland and the UK, but not the USA), the patient (or family member/friend) can inject LAN if they are on a stable dose, their doctor agrees, and they received training. A nurse/doctor must inject OCT. In PRESTO 2, about 40% of non-US patients who were eligible injected themselves (or were helped by a family member/friend). This may explain why more patients reported anxiety in the LAN group. PRESTO 2 provides important insights into patients' experiences of receiving somatostatin analogs and helps identify areas for improving patient care.
