RESUMEN
AIM: To evaluate the efficacy and safety of triptorelin after radical prostatectomy (RP) in patients with negative lymph nodes. METHODS: PRIORITI (NCT01753297) was a prospective, open-label, randomized, controlled, phase 4 study conducted in China and Russia. Patients with high-risk (Gleason score ≥ 8 and/or pre-RP prostate-specific antigen [PSA] ≥ 20 ng/mL and/or primary tumor stage 3a) prostate adenocarcinoma without evidence of lymph node or distant metastases were randomized to receive triptorelin 11.25 mg at baseline (≤ 8 weeks after RP) and at 3 and 6 months, or active surveillance. The primary endpoint was biochemical relapse-free survival (BRFS), defined as the time from randomization to biochemical relapse (BR; increased PSA > 0.2 ng/mL). Patients were monitored every 3 months for at least 36 months; the study ended when 61 BRs were observed. RESULTS: The intention-to-treat population comprised 226 patients (mean [standard deviation] age, 65.3 [6.4] years), of whom 109 and 117 were randomized to triptorelin or surveillance, respectively. The median BRFS was not reached. The 25th percentile time to BRFS (95% confidence interval) was 39.1 (29.9-not estimated) months with triptorelin and 30.0 (18.6-42.1) months with surveillance (p = 0.16). There was evidence of a lower risk of BR with triptorelin versus surveillance but this was not statistically significant at the 5% level (p = 0.10). Chemical castration was maintained at month 9 in 93.9% of patients who had received triptorelin. Overall, triptorelin was well tolerated and had an acceptable safety profile. CONCLUSION: BRFS was observed to be longer with triptorelin than surveillance, but the difference was not statistically significant.
RESUMEN
BACKGROUND AND OBJECTIVE: The tyrosine kinase inhibitors cabozantinib and axitinib have been widely used in England to treat advanced renal cell carcinoma following prior vascular endothelial growth factor-targeted therapy, but data on real-world usage remain limited. Our objective was to describe the real-world treatment patterns and outcomes of patients with advanced renal cell carcinoma who received second-line or later-line (≥ 2L) cabozantinib or axitinib after vascular endothelial growth factor-targeted therapy in clinical practice in England. METHODS: This retrospective cohort study used clinical practice data (collected 2011-20) from the English Cancer Analysis System database. Patient characteristics, treatment sequence and duration, and overall survival (time from initiation of cabozantinib/axitinib treatment to death) were evaluated. RESULTS: Data from 1485 eligible adults with advanced renal cell carcinoma were analyzed: 440 received ≥ 2L cabozantinib (2L for 88.6% of them); 1045 received ≥ 2L axitinib (2L for 89.5%). The most common first-line treatments were sunitinib (2L cabozantinib subcohort, 48%; 2L axitinib subcohort, 46%) and pazopanib (46% and 54%, respectively); nivolumab was the most common third-line treatment (18% and 19%, respectively). Median (interquartile range) 2L therapy duration was 5.52 (2.73-11.74) months for cabozantinib and 4.60 (1.45-12.36) months for axitinib. Following adjustment for potential confounders using inverse probability weighting, overall survival (median [interquartile range]) was longer for ≥ 2L cabozantinib (11.2 [5.7-28.0] months) than for ≥ 2L axitinib (10.4 [4.7-22.0] months; log-rank p = 0.0034). CONCLUSIONS: The Cancer Analysis System database is a valuable research resource providing extensive real-world clinical data. Real-world overall survival was longer with ≥ 2L cabozantinib than with axitinib. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT04637204; registered November 2020.
Cabozantinib and axitinib are anticancer drugs called tyrosine kinase inhibitors. They work by blocking the activity of proteins that cancer cells use to help them divide and grow. Cabozantinib and axitinib are treatment options for a common type of kidney cancer called renal cell carcinoma (RCC). There is evidence about how well cabozantinib and axitinib work in clinical trials, but it is less clear how well they work in standard practice outside of clinical trials. We investigated how cabozantinib and axitinib are used and how well they work as part of 'real-world' RCC care. We did this by analyzing patient data from an English cancer database. All patients in the study had advanced RCC and had been treated with at least one previous anticancer drug. This includes a type of drug that blocks new blood vessels forming, which tumors need for rapid growth. Most of the 1485 patients received cabozantinib or axitinib after receiving only one previous anticancer drug. These patients were treated for a median of 5.5 months with cabozantinib and 4.6 months with axitinib. Patients lived for a median of 11.2 months after starting cabozantinib treatment and a median of 10.4 months after starting axitinib treatment. This study provides new evidence showing how well cabozantinib and axitinib work in everyday RCC care. The results add to those from clinical trials and show the value of the English cancer registry for conducting studies of routine cancer care.
RESUMEN
Context: Treatment of acromegaly is multimodal for many patients, and medical treatments include somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and growth hormone receptor antagonists (GHRAs). However, recent real-world evidence on treatment patterns for patients with acromegaly is limited. Objective: This study evaluated medication usage, treatment changes, adherence, persistence, comorbidities, and health care resource utilization using deidentified data from MarketScan, a US claims database. Methods: Eligible patients (n = 882) were those receiving monotherapy or combination therapy for ≥90 days without treatment gaps. Results: Mean age at diagnosis was 48.6 years; 50.1% of patients were female. Over half (59.4%) had 1 line of treatment (LOT); 23.1% had 2 LOTs; 17.5% had at least 3 LOTs. Most patients (94.6%) initiated treatment with monotherapies. The most common first-line monotherapy treatments were cabergoline (DA, 36.8%), octreotide long-acting release (first-generation SRL, 29.5%), and lanreotide depot (first-generation SRL, 22.5%). Adherence for first-line treatments (proportion of days covered) was higher for first-generation SRLs (lanreotide depot: 0.8) compared with DAs (0.7). Treatment persistence (time between the first treatment record and a change in LOT/censoring) in LOT 1 was higher for GHRAs (24.8 months) and first-generation SRLs (20.0 months) compared with DAs (14.4 months). Female patients and those diagnosed at a younger age were more likely to have shorter treatment persistence. The most prevalent comorbidities were hyperlipidemia, essential hypertension, and sleep apnea. Conclusion: Patients with more comorbidities had more health care visits during the first year after diagnosis, suggesting increased disease burden. Real-world evidence on treatment patterns provides insights into recommendations for individualized therapy.
RESUMEN
IMPORTANCE: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) can affect patient health-related quality of life (HRQoL). Appropriate information may improve their adherence to treatment and quality of life. OBJECTIVE: To evaluate the change in patient's perceptions of the level of information at lanreotide (LAN) treatment initiation for GEP-NETs vs after 6 months. DESIGN: OPERA (NCT03562091) was a prospective, longitudinal, noninterventional study. SETTING: Thirty-one centers in France specialized in the management of patients with NETs. INTERVENTION: Planned clinical visits at enrollment and end-of-study visits at month 6, with completion of the European Organisation for Research and Treatment of Cancer 25-item Quality of Life Questionnaire-Information Module (QLQ-INFO25) and 30-item Quality of Life Questionnaire-Core. MAIN OUTCOME: Absolute change in the patient's perception of the information between baseline and month 6, using the relevant domains of the QLQ-INFO25. Endpoints measured at baseline and month 6 for at least 1 of the 3 targeted QLQ-INFO25 dimensions of the primary endpoint. RESULTS: Ninety-three of the 115 patients enrolled completed ≥1 primary endpoint information dimension. Mean (SD) scores for the primary endpoint information dimensions were high at baseline (disease, 63.41 [20.71]; treatment, 58.85 [19.00]; supportive care, 26.53 [24.69]; maximum 100). There were no significant changes between baseline (98.34% CI) and 6 months (disease, -2.84 [-8.69, 3.01; P = .24]; treatment, -4.37 [-11.26, 2.52; P = .13]; supportive care, 0.46 [-6.78, 7.70; P = .88]), and in HRQoL between baseline and 6 months. CONCLUSIONS AND RELEVANCE: The lack of change in patient's perceptions of the disease, treatment, and supportive care information provided over the first 6 months of LAN treatment may suggest that physicians provided adequate information at the treatment initiation.

Lanreotide autogel/depot (LAN) is a somatostatin analog used in first-line treatment for neuroendocrine tumors (NETs). The aim of HomeLAN was to evaluate the satisfaction with injection experience among patients with NETs receiving at-home LAN injection via patient support programs (PSPs). This was an international, non-interventional, cross-sectional, online survey in adults with NETs enrolled in PSPs, receiving LAN injections at home, administered by a healthcare professional (HCP) or administered independently (self or caregiver administering injection). The primary endpoint was satisfaction with the most recent LAN injection. Secondary endpoints included the level of anxiety prior to injection, impact on daily life, and the extents to which participants felt in control of their life and agreed that home administration met their medical needs. In total, 111 participants from Belgium, Greece, the Netherlands, and Spain completed the survey (50.5% male; mean age, 63.6 years; most common primary tumor site was intestine [47.7%]). For 99 participants, their most recent injection was administered by an HCP. Overall, 95.5% of all participants were satisfied with their most recent injection experience (95% confidence interval: 89.89%-98.06%); 67% reported experiencing no anxiety prior to injection, 91.0% reported that home injection had a "great deal" or "quite a bit" of positive impact on their daily life, and 85.6% strongly agreed that the PSP met their medical needs. In the HCP injection subgroup, 71.7% reported that this mode of administration helped them to feel in control of their lives. In this patient survey, satisfaction levels were high among patients with NETs receiving LAN injections at home via a LAN PSP. Most patients did not experience anxiety prior to their most recent injection and acknowledged that thanks to their treatment they had a good quality of life despite their disease. Most strongly agreed that the PSP met their medical needs, which highlights the valuable service that LAN PSPs provide for patients with NETs.

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.

INTRODUCTION: Lanreotide autogel (LAN) and temozolomide (TMZ) are guidelines-recommended monotherapies for thoracic neuroendocrine tumors (carcinoids; T-NETs), but prospective data for both combined and monotherapies are lacking. ATLANT (NCT02698410) evaluated efficacy and safety of LAN/TMZ in progressive T-NETs. METHODS: ATLANT was a 12-month, Italian, phase 2, single-arm, open-label, multicenter pilot study. Eligible patients had unresectable, locally advanced/metastatic, well-/moderately differentiated T-NETs with radiological progression. Patients received subcutaneous LAN 120 mg every 28 days and oral TMZ 250 mg/day for 5 consecutive days every 28-day cycle. Main endpoints are disease control rate (DCR) at 9 months (primary; investigator-assessed), median progression-free survival (PFS), biomarkers, and safety. RESULTS: The number of patients was 40; 60% were male. Primary tumor site was lung (90%) and thymus (10%). Carcinoid type was typical (20.0%) and atypical (52.5%). DCR at 9 months was 35.0% (95% confidence interval (CI) 20.63-51.68; nonacceptability threshold ≤10%, p < 0.0001; not significantly above clinically relevant threshold ≥30%, p = 0.2968). DCR between 7.5 and 10.5 months (sensitivity analysis) was 45.0% (95% CI: 29.26-61.51) and clinically relevant (p = 0.0320 at ≥30% threshold). Median PFS was 37.1 (95% CI: 24.1-52.9) weeks. No association was observed between biomarker variations (chromogranin A, neuron-specific enolase, somatostatin receptor type-2, Ki-67, 6-O-methylguanine-DNA-methyl-transferase) and DCR or PFS. Most patients (97.5%) had treatment-emergent adverse events (TEAEs); 72.5% had treatment-related TEAEs. TEAEs were mainly grade 1/2. No unanticipated TEAEs were reported. CONCLUSIONS: This study showed that the LAN/TMZ combination has promising efficacy in progressive T-NETs, and was well tolerated. Larger studies are warranted to support the clinical benefits of LAN/TMZ in patients with T-NETs.

PURPOSE: A systematic literature review was conducted to assess the use of home injections (self/partner/healthcare provider [HCP]-administered) of somatostatin analogs (SSAs) as an alternative to healthcare-setting injections in patients with acromegaly and neuroendocrine tumors (NETs). METHODS: MEDLINE/Embase/the Cochrane Library (2001-September 2021), key congresses (2019-2021), and bibliographies of relevant systematic reviews were searched. Eligible studies reported on efficacy/effectiveness, safety, adherence, patient-reported outcomes (PROs), and economic outcomes in populations receiving home injections of SSAs. RESULTS: Overall, 12 studies were included, all reporting on SSAs (lanreotide Autogel/Depot or octreotide long-acting release) in acromegaly or NETs. Across four studies, home injection was associated with similar disease control in patients with acromegaly/NETs compared with healthcare-setting administration. High rates of treatment adherence were shown in two studies of patients with acromegaly receiving lanreotide injections at home. Two studies reported non-serious adverse events; incidence of adverse reactions was similar in both the home and healthcare administration settings. Preference for injection setting varied between studies and indications; nonetheless, higher satisfaction/convenience (>75% patients) was reported for home injections. Self- or partner-injection was associated with economic savings compared with administration in the healthcare setting across five studies. CONCLUSION: Efficacy/effectiveness, adherence, and safety outcomes of SSAs in the home injection setting were similar to those in the healthcare setting, with high reported satisfaction and convenience. Self/partner injection also resulted in cost savings. These findings provide a basis to understand outcomes related to home injection and encourage healthcare providers to discuss optimal treatment choices with their patients.

CALM-NET was a phase IV exploratory study in the UK that aimed to evaluate if the presence of circulating tumour cells (CTCs) at baseline predicted symptomatic response in patients with midgut neuroendocrine tumours (NETs) treated with lanreotide autogel (LAN). Adults with functional, well/moderately differentiated (Ki-67 <20%) midgut NETs received LAN 120 mg/28 days for 1 year. CTCs were present in blood if enumeration was >0. Primary endpoint was the clinical value of baseline CTCs to predict symptomatic response (decrease in diarrhoea or flushing of ≥50% frequency, or ≥1 severity level). Other endpoints included progression-free survival (PFS) and correlations between plasma and urinary biomarkers (including 5-hydroxyindoleacetic acid [5-HIAA]). Fifty patients were enrolled; 40 completed the study. Baseline CTCs were present in 22 (45.8%) patients (missing baseline CTC status n = 2). Overall, 87.5% (95% confidence interval [CI]: 73.9; 94.5) of patients had a symptomatic response; a 5.9-fold higher odds of symptomatic response in patients without CTC versus patients with CTC at baseline was observed, although this was not statistically significant (odds ratio: 0.17 [95% CI: 0.02; 1.65], p = .126). One-year PFS rate was 66.4% (95% CI: 48.8; 79.2). Biomarker concentrations did not correlate to baseline CTC status. However, there was a strong correlation between plasma and urinary 5-HIAA (Spearman correlation coefficients ≥0.87 [p < .001], all time points). In conclusion, patients without CTC at baseline may be more likely to achieve a symptomatic response following LAN treatment than patients with CTC. Plasma 5-HIAA correlated with urinary 5-HIAA during LAN treatment. ClinicalTrials.gov identifier: NCT02075606.

Reported incidences of neuroendocrine tumors (NETs) appear to be increasing, possibly due to greater disease awareness and increased accuracy of diagnosis. Approximately 20% of patients with NETs develop carcinoid syndrome (CS), which arises from elevated secretion of bioactive compounds, including serotonin, from NETs. This leads to symptoms including diarrhea and flushing, which result in weight loss and are associated with considerable negative impact on patients' quality of life. We previously reported significant weight gain and improved nutritional status in patients with NETs who were treated with telotristat ethyl (TE) for 12 weeks. In this follow-up analysis, using pooled data from the 36-week open-label extensions of the TELESTAR (NCT01677910) and TELECAST (NCT02063659) phase III trials, we demonstrate that improvements in weight and nutritional parameters were sustained or further improved in patients with CS through to week 48 of treatment with TE. At week 48/end of study, 68.7% of all patients maintained a stable weight or had weight gain and the mean changes from baseline in cholesterol and albumin levels in patients treated with TE were +0.41 mmol/L and -0.34 g/L, respectively. These results indicate that TE, alongside routine clinical practice, may provide long-term benefits in nutritional intake and weight evolution in patients with CS.

INTRODUCTION: This prospective, single-arm, phase 2 study assessed the efficacy and safety of lanreotide autogel (LAN) administered at a reduced dosing interval in patients with progressive neuroendocrine tumours (NETs) after LAN standard regimen. METHODS: Patients had metastatic or locally advanced, grade 1 or 2 midgut NETs or pancreatic NETs (panNETs) and centrally assessed disease progression on LAN 120 mg every 28 days. They were treated with LAN 120 mg every 14 days for up to 96 weeks (midgut cohort) or 48 weeks (panNET cohort). The primary end-point was centrally assessed progression-free survival (PFS). PFS by Ki-67 categories was analysed post hoc. Secondary end-points included quality of life (QoL) and safety. RESULTS: Ninety-nine patients were enrolled (midgut, N = 51; panNET, N = 48). Median (95% CI) PFS was 8.3 (5.6-11.1) and 5.6 (5.5-8.3) months, respectively. In patients with Ki-67 ≤ 10%, median (95% CI) PFS was 8.6 (5.6-13.8) and 8.0 (5.6-8.3) months in the midgut and panNET cohorts, respectively. Patients' QoL did not deteriorate during the study. There were no treatment-related serious adverse events and only two withdrawals for treatment-related adverse events (both in the panNET cohort). CONCLUSIONS: In patients with progressive NETs following standard-regimen LAN, reducing the dosing interval to every 14 days provided encouraging PFS, particularly in patients with a Ki-67 ≤ 10% (post hoc); no safety concerns and no deterioration in QoL were observed. Increasing LAN dosing frequency could therefore be considered before escalation to less well-tolerated therapies.

INTRODUCTION: Patients with acromegaly have substantially reduced quality of life (QoL). This study evaluated QoL in patients with acromegaly treated with lanreotide autogel. MATERIAL AND METHODS: This was a prospective, non-interventional, observational, multi-centre study conducted in Poland (NCT02396966). We included patients with acromegaly, who received treatment with lanreotide autogel 120mg for ≥ 3 months and < 3 years. Patients were assessed approximately every 4-5months for twoyears (six visits). QoL was measured with the Acromegaly Quality of Life Questionnaire (AcroQoL). RESULTS: Of 152 patients enrolled from November 2014 to May 2018 in 37 centres, 24 were excluded due to major protocol deviations. The results are reported for the study population (n = 128). At baseline, the median [95% confidence interval (CI)] time from diagnosis was 3.3 (2.8, 4.2)years, and the median time since lanreotide initiation was 13.4 (9.9, 17.3) months. Symptoms of acromegaly were present at baseline in 86% of patients (headache, 57%; sweating, 58%; joint symptoms, 64%); symptoms remained unchanged at two years in 82% of patients. At baseline, 27% of patients had hormonal control (growth hormone < 2.5 µg/L and insulin-like growth factor-1 within the normal range); hormonal control status did not change during the study period in over 81% of patients. At baseline, 88% of patients were either very satisfied or satisfied with treatment; treatment satisfaction was unchanged in 62% of patients over the study period. Mean (95% CI) AcroQoL scores at baseline were as follows: total, 50.3 (47.3, 53.3); physical dimension, 48.8 (45.2, 52.4); psychological dimension, 51.3 (48.2, 54.4); appearance subdimension, 40.7 (37.5, 43.8); and personal relations subdimension, 62.5 (58.8, 66.2). The psychological appearance subscore improved by 3.8 points (1.2, 6.5) over the two years; scores in the remaining dimensions and subdimensions did not change substantially. The total AcroQoL score remained unchanged over the twoyears, regardless of prior acromegaly treatment, surgery or radiotherapy, hormonal control, or lanreotide dosing interval. No new safety findings were identified. CONCLUSIONS: AcroQoL total scores and physical and psychological subscores remained stable but impaired among patients with long-lasting acromegaly treated with lanreotide autogel for two years. The psychological appearance subdimension improved numerically.

BACKGROUND: The long-acting somatostatin analog lanreotide autogel is effective in the treatment of patients with neuroendocrine tumors. OBJECTIVE: To evaluate the long-term treatment response in patients with neuroendocrine tumors receiving lanreotide autogel in routine clinical practice. METHODS: Non-interventional, 24-month study in patients with neuroendocrine tumors treated with lanreotide autogel (NCT01840449). RESULTS: Patients (n=80) from 26 centers in Germany and Austria were enrolled. Neuroendocrine tumors were mainly grade 1/2, metastasized, intestinal, and associated with carcinoid syndrome; 88.9% had received previous neuroendocrine tumor treatment. Of those, 84.4% had previous surgery, 18.7% had received octreotide. The primary endpoint, defined by a <50% chromogranin A increase at month 12 compared with the lowest value between baseline and month 3 was achieved by 89.5% patients. Stable disease according to Response Evaluation Criteria in Solid Tumors 1.1 was observed in 76.9 and 75.0% patients at months 12 and 24 of lanreotide treatment, respectively. Mean change of chromogranin A levels from baseline to month 24 was -0.12 × upper limit of normal (95% CI, -0.22; -0.45). In a post hoc analysis, 38.5% of the subgroup of patients with carcinoid syndrome had daily diarrhea at baseline vs. 21.4% at month 24. At baseline, 27.8% of patients received lanreotide 120 mg every 4 weeks vs. 56.7% at month 24. Quality of life data were heterogeneous. No new safety issues arose and/or required further investigation. CONCLUSIONS: Our study reflects routine lanreotide autogel use in patients with advanced/metastatic neuroendocrine tumors.

CONTEXT: The SAGIT® instrument (SAGIT) has been developed to enable accurate characterization of acromegaly disease activity. OBJECTIVE: We evaluated the ability of SAGIT to discriminate acromegaly disease control status. METHODS: This multicenter, noninterventional, prospective and retrospective, longitudinal study, conducted at academic and private clinical practice sites, included patients agedâ ≥â 18 years with a diagnosis of controlled (nâ =â 109) or non-controlled (nâ =â 105) acromegaly, assessed by clinical global evaluation of disease control (CGE-DC) questionnaire, investigator therapeutic decision, and international guidelines. Control status was not determined at baseline for 13 patients. Since 9 patients were enrolled retrospectively, all presented analyses are based on the prospective population (Nâ =â 227). Patients were assessed over a 2-year follow-up period. Classification and regression tree (CART) analyses were performed to investigate how SAGIT components at baseline (signs/symptoms [S], associated comorbidities [A], growth hormone levels [G], insulin-like growth factor 1 levels [I], tumor features [T]) discriminate between controlled and non-controlled acromegaly. RESULTS: Baseline mean subscores S, G, I, and T were significantly lower in patients with CGE-DC controlled vs CGE-DC non-controlled acromegaly. SAGIT components I and G for CGE-DC and S, A, G, I, and T for the clinician's therapeutic decision were retained by CART analyses. For international guidelines, only SAGIT component I was retained. The risk for undergoing ≥ 1 treatment change during the study was 3.44 times greater for CGE-DC non-controlled acromegaly relative to CGE-DC controlled acromegaly. CONCLUSION: The SAGIT instrument is a valid and sensitive tool to comprehensively and accurately assess acromegaly severity.

BACKGROUND: Evidence from controlled trials has shown that lanreotide autogel is effective in achieving biochemical and symptom control in patients with acromegaly. However, it is important to better understand the real-world patient population receiving lanreotide autogel treatment. METHODS: In this non-interventional study the long-term treatment response to lanreotide autogel in adult patients with acromegaly from office-based centers or clinics in Germany, Austria and Switzerland was studied. Assessments included growth hormone and insulin-like growth factor-I levels, symptoms, quality of life, lanreotide plasma levels and tumor somatostatin receptor subtype expression. The primary endpoint was achievement of full biochemical control, defined as growth hormone ≤2.5 µg/L and insulin-like growth factor I normalization at month 12. RESULTS: 76 patients were enrolled from 21 sites. 7/51 (13.7%) patients of the efficacy population had full biochemical control at baseline, 15/33 (45.5%) at month 12 and 10/26 (38.5%) at month 24 of treatment. At 12 months of treatment higher rates of biochemical control were observed in the following subgroups: older patients (>53 years [median]), females, treatment-naïve patients, and patients with a time since diagnosis of longer than 1.4 years (median). No clinically relevant differences in acromegaly symptoms or quality of life scores were observed. Median fasting blood glucose and glycated hemoglobin levels remained unchanged throughout the study. No new safety signals were observed. Overall tolerability of treatment with lanreotide autogel was judged by 80.8% of the enrolled patients at month 12 as 'very good' or 'good'. CONCLUSION: Treatment with lanreotide autogel in a real-world setting showed long-term effectiveness and good tolerability in patients with acromegaly.

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.

PURPOSE: PRELUDE aimed to assess use and effectiveness/safety of lanreotide autogel/depot (LAN) combined with 177Lu-DOTATOC or 177Lu-DOTATATE (LAN-peptide receptor radionuclide therapy [PRRT]) in patients with progressive neuroendocrine tumours (NETs). METHODS: International, non-interventional, retrospective, non-comparative analysis of medical records from patients with progressive metastatic or locally advanced grade 1 or 2 gastroenteropancreatic (GEP)- or lung-NETs. The primary endpoint was progression-free survival (PFS) at end of last LAN-PRRT cycle. Secondary endpoints included PFS at last available follow-up, best overall response, objective response rate (ORR), presence and severity of diarrhoea and flushing, and safety. Post-hoc analyses were conducted to determine pre-treatment tumour growth rate (TGR) cutoffs that best predicted the ORR during treatment. RESULTS: Forty patients were enrolled (GEP-NETs, n = 39; lung-NETs, n = 1). PFS rates were 91.7% at end of last LAN-PRRT cycle and 95.0% at last available follow-up. In the full analysis set, best overall response among patients with GEP-NETs (n = 23) was stable disease (n = 14, 60.9%), partial response (n = 8, 34.8%) and progressive disease (n = 1, 4.3%). The ORR was 27.3% at end of last LAN-PRRT cycle and 36.8% at last available follow-up. Optimal baseline TGR cutoffs for predicting ORR at these time points were 1.18% and 0.33%, respectively. At baseline, 81.0% of patients had diarrhoea or flushing; both remained stable or improved in most cases. No increased adverse drug reactions were reported. CONCLUSION: Despite the major recruitment shortfall for the PRELUDE study, effectiveness data were encouraging in this selected population, highlighting the potential usefulness and feasibility of LAN combined with and after PRRT in patients with GEP-NETs. The study also identified challenges associated with evaluating clinical practice in a rare-disease setting and highlighted the need for standardisation of PRRT procedures.

PURPOSE: PRIMARYS (NCT00690898) was a 48-week, open-label, phase 3b study, evaluating treatment with the somatostatin receptor ligand lanreotide autogel (stable dose: 120 mg/28 days) in treatment-naïve patients with growth hormone (GH)-secreting pituitary macroadenoma. This post hoc analysis aimed to evaluate factors predictive of long-term responses. METHODS: Potential predictive factors evaluated were: sex, age, and body mass index at baseline; and GH, insulin-like growth factor-1 (IGF-1), and tumor volume (TV) at baseline and week 12, using univariate regression analyses. Treatment responses were defined as hormonal control (GH ≤ 2.5 µg/L and age- and sex-normalized IGF-1), tight hormonal control (GH < 1.0 µg/L and normalized IGF-1), or ≥ 20% TV reduction (TVR). Receiver-operating-characteristic (ROC) curves were constructed using predictive factors significant in univariate analyses. Cut-off values for predicting treatment responses at 12 months were derived by maximizing the Youden index (J). RESULTS: At baseline, older age, female sex, and lower IGF-1 levels were associated with an increased probability of achieving long-term hormonal control. ROC area-under-the curve (AUC) values for hormonal control were high for week-12 GH and IGF-1 levels (0.87 and 0.93, respectively); associated cut-off values were 1.19 µg/L and 110% of the upper limit of normal (ULN), respectively. Results were similar for tight hormonal control (AUC values: 0.92 [GH] and 0.87 [IGF-1]; cut-off values: 1.11 µg/L and 125% ULN, respectively). AUC and J values associated with TVR were low. CONCLUSIONS: The use of predictive factors at baseline and week 12 of treatment could inform clinical expectations of the long-term efficacy of lanreotide autogel.

Background: Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) are neoplasms derived from the endocrine system in the gastrointestinal tract and pancreas. Treatment options include surgery; pharmacological treatments like somatostatin analogues (SSA), interferon alpha, molecular targeted therapy and chemotherapy; and peptide receptor radionuclide therapy. The objective of this study was to describe treatment patterns and survival among patients with metastatic GEP-NET grade 1 or 2 in Sweden. Methods: Data was obtained via linkage of nationwide registers. Patients diagnosed with metastatic GEP-NET grade 1 or 2 in Sweden between 2005 and 2013 were included (n=811; National population). In addition, medical chart review was performed for the subpopulation diagnosed at Sahlgrenska University Hospital, Gothenburg (n=127; Regional population). Treatment patterns, including treatment sequences, and overall survival were assessed. Results: Most patients had small intestinal NET (76%). In the regional population, 72% had grade 1 tumours; 50% had functioning tumours. The two most common first-line treatments were surgery (57%) and SSA (25%). After first-line surgery, 46% received SSA, while 40% had no further treatment. After first-line SSA, 52% received surgery, while 27% had no further treatment. Overall median survival time from date of diagnosis was 7.0 years (95% CI 6.2-not reached). Among patients with distant metastases, pancreatic NET (vs. small intestinal NET) was associated with poorer survival (HR 1.9; 95% CI 1.1-3.3), as were liver metastases (HR 3.2; 95% CI 1.5-7.0). Conclusions: First-line surgery was typically followed by SSA or no further treatment. Among patients with distant metastases, pancreatic NET or liver metastases were associated with a poorer survival.
