Abstract
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.

Abstract
The application of nanomotors for cancer diagnosis and therapy is a new and exciting area of research, which when combined with precision nanomedicine, promises to solve many of the issues encountered by previous development of passive nanoparticles. The goal of this article is to introduce nanomotor and nanomedicine researchers to the deep pool of knowledge available regarding cancer cell biology and biochemistry, as well as provide a greater appreciation of the complexity of cell membrane compositions, extracellular surfaces, and their functional consequences. A short description of the nanomotor state-of-art for cancer therapy and diagnosis is first provided, as well as recommendations for future directions of the field. Then, a biomolecular targeting toolbox has been collated for researchers looking to apply their nanomaterial of choice to a biological setting, as well as providing a glimpse into currently available clinical therapies and technologies. This toolbox contains an overview of different classes of targeting molecules available for high affinity and specific targeting and cell surface targets to aid researchers in the selection of a clinical disease model and targeting methodology. It is hoped that this review will provide biological context, inspiration, and direction to future nanomotor and nanomedicine research.

A systematic literature review to evaluate extended dosing intervals in the pharmacological management of acromegaly. Pituitary 2023; 26:9-41. [PMID: 36447058 PMCID: PMC9708130 DOI: 10.1007/s11102-022-01285-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/14/2022] [Indexed: 12/05/2022]
Abstract
PURPOSE This systematic literature review investigated whether extended dosing intervals (EDIs) of pharmacological acromegaly treatments reduce patient burden and costs compared with standard dosing, while maintaining effectiveness. METHODS MEDLINE/Embase/the Cochrane Library (2001-June 2021) and key congresses (2018-2021) were searched and identified systematic literature review bibliographies reviewed. Included publications reported on efficacy/effectiveness, safety and tolerability, health-related quality of life (HRQoL), and patient-reported and economic outcomes in longitudinal/cross-sectional studies in adults with acromegaly. Interventions included EDIs of pegvisomant, cabergoline, and somatostatin receptor ligands (SRLs): lanreotide autogel/depot (LAN), octreotide long-acting release (OCT), pasireotide long-acting release (PAS), and oral octreotide; no comparator was required. RESULTS In total, 35 publications reported on 27 studies: 3 pegvisomant monotherapy, 11 pegvisomant combination therapy with SRLs, 9 LAN, and 4 OCT; no studies reported on cabergoline, PAS, or oral octreotide at EDIs. Maintenance of normal insulin-like growth factor I (IGF-I) was observed in ≥ 70% of patients with LAN (1 study), OCT (1 study), and pegvisomant monotherapy (1 study). Achievement of normal IGF-I was observed in ≥ 70% of patients with LAN (3 studies) and pegvisomant in combination with SRLs (4 studies). Safety profiles were similar across EDI and standard regimens. Patients preferred and were satisfied with EDIs. HRQoL was maintained and cost savings were provided with EDIs versus standard regimens. CONCLUSIONS Clinical efficacy/effectiveness, safety, and HRQoL outcomes in adults with acromegaly were similar and costs lower with EDIs versus standard regimens. Physicians may consider acromegaly treatment at EDIs, especially for patients with good disease control.

Abstract
INTRODUCTION A common feature shared by most neuroendocrine tumors (NETs) is the expression on their surface of somatostatin receptors (SSTRs) that are essential for their pathophysiological regulation, diagnosis, and management. The first-generation synthetic somatostatin analogs (SSAs), octreotide and lanreotide, constitute the cornerstone of treatment for growth hormone secreting pituitary adenomas and functioning, progressive functioning, and non-functioning gastro-entero-pancreatic (GEP-NETs). SSAs exert their mechanism of action through binding to the SSTRs; however, their therapeutic response is frequently attenuated or diminished by the development of resistance. The phenomenon of resistance is complex implicating the presence of additional epigenetic and genetic mechanisms. AREAS COVERED We aim to analyze the molecular, genetic, and epigenetic mechanisms of resistance to SSA treatment. We also summarize recent clinical data related to the development of resistance on conventional and non-conventional modes of administration of the first-generation SSAs and the second-generation SSA pasireotide. We explore mechanisms used to counteract the resistance to SSAs using higher doses or more frequent mode of administration of SSAs and/or combination treatments. EXPERT OPINION There is considerable heterogeneity in the development of resistance to SSAs that is tumor-specific necessitating the delineation of the underlying pathophysiological processes to further expand their therapeutic applications.

Abstract
PURPOSE Acromegaly is a rare chronic disease characterized by systemic comorbidity and reduced quality of life. Although achieving biochemical control has always been the primary goal of acromegaly therapy, recent evidence has shown that the traditional assessment does not adequately capture the complexity of symptoms and patients' perception. These findings result in the need to improve a fast decision-making process of the clinician, who should not only take into account biochemical-instrumental criteria, but also patients' symptoms. With the aim of supporting the clinician in the diagnostic and therapeutic decision-making process several disease-specific tools have been developed. The aim of this review is to provide a description of the acromegaly-specific tools, presenting their main features, their application in daily practice, and their efficacy and utility. METHODS A systematic search of Medline/PubMed, ISI-Web of Knowledge, and Google Scholar databases was done. RESULTS Specific instruments and questionnaires have recently been developed to assist clinicians in the assessment of acromegaly. These are either Patient-Reported Outcome tools, such as Acromegaly Quality of Life Questionnaire (AcroQoL) and Pain Assessment Acromegaly Symptom Questionnaire (PASQ), or Clinician-Reported Outcome tools, such as ACROSCORE, SAGIT® and Acromegaly Disease Activity Tool (ACRODAT®). Such tools are extremely flexible and, therefore, have been widely adopted by endocrinologists and other professionals, so much so that they have also been included as recommendations in the 2018 international guidelines. CONCLUSION Questionnaires and tools are useful in the management of acromegaly patients. They help clinicians evaluate patients' symptoms and could assist in the evaluation of disease activity.

Abstract
Background Acromegaly is a chronic disease significantly affects the physical, emotional, and health-related aspects of patients' life. This study aimed to validate the Acromegaly Quality of Life Questionnaire (AcroQoL) for the Persian-speaking population. Methods This cross-sectional study recruited 73 Iranian patients with a confirmed diagnosis of acromegaly. The content validity of the scales was evaluated by an expert panel of eight endocrinologists applying content validity index (CVI) and content validity ratio (CVR). Construct validity was assessed by using confirmatory factor analysis. Internal consistency was assessed on the basis of Cronbach’s alpha, and a goodness-of-fit (GoF) index was calculated to display whether the model fitted the data. Results CVI and CVR yielded values of 0.85 and 0.80, respectively (Acceptable CVI: > 0.78 and CVR: > 0.75). The average variances extracted (AVE) from physical and psychological dimensions were 0.520 and 0.462, respectively, exceeding the minimum criterion of 0.40. Cronbach’s alpha for physical and psychological dimensions equaled 0.868 and 0.866, respectively, indicating the adequate internal consistency of multiple items for each construct. The subscales’ R square and path coefficient were greater than the recommended threshold as 0.75 (physical dimension: 0.778, psychological dimension: 0.873), demonstrating the suitability of this criterion. Finally, the GoF value of 0.29 indicated the model's moderate fit. Conclusions The findings revealed that the Persian version of AcroQoL is of adequate validity and reliability for evaluating the quality of life of Iranian people with acromegaly.

Abstract
BACKGROUND Patients with acromegaly require lifelong medication; a longer dosing interval would reduce treatment burden. This study investigated the pharmacokinetics, pharmacodynamics and safety profile of a new prolonged-release formulation (PRF) of lanreotide every 12 weeks. RESEARCH DESIGN AND METHODS In this multicenter, open-label, dose-ascending study, cohorts of nine patients with acromegaly received single doses of lanreotide PRF according to a 3 + 3 + 3 scheme in order to determine the maximum tolerated dose (MTD). Following a 12-week treatment period, patients were followed up for a further 12 weeks. Serum lanreotide, insulin-like growth factor-1 and growth hormone concentrations were analyzed. Adverse events were monitored throughout the study. RESULTS The MTD was not reached. Peak lanreotide serum concentration values were similar in all cohorts, whereas area under the curve values from time zero to 85 days increased but were not dose-proportional. The apparent elimination half-life of lanreotide PRF was approximately 54-63 days, in line with the expected prolonged-release characteristics. Growth hormone and insulin-like growth factor-1 levels were generally stable. CONCLUSIONS The safety and tolerability profile was in-line with the known safety profile of lanreotide autogel. Lanreotide PRF was well tolerated and the pharmacokinetic profile suggests that a dosing interval of 12 weeks could be achievable.

Abstract
AIM The aim of this study is to assess the benefits of a nurse-led home injection service for somatuline autogel-treated patients with acromegaly, including the adherence to treatment and disease control. METHODS Historical prospective data of all patients with acromegaly initiating somatuline autogel between November 14, 2000, and March 9, 2020, who voluntarily enrolled in the nurse-led home injection service between January 1, 2018 and June 30, 2020. Adherence to treatment was calculated as the number of administered injections divided by the number of expected injections during the follow-up period. Excellent adherence to treatment was defined when >90% of scheduled injections were administered, while low adherence was defined when patients received <80% of expected injections. The primary outcome was the adherence to treatment. RESULTS The cohort included 88 patients (mean age ± SD, 59.8 ± 14.9 years, 53% men). Average adherence to treatment was 93 ± 8% (range 62-100%). Excellent adherence was documented in 65 participants (74%), of which 29 patients (33%) received all scheduled injections. Low adherence to treatment was recorded in seven patients (8%). Average adherence was high independent of gender, age, prior surgery, or radiation therapy, or whether somatuline autogel was used as monotherapy or in combination regimens. However, excellent adherence decreased with increased somatuline dose and with dosing interval of 21 days. Average adherence was slightly higher in patients with biochemically controlled acromegaly. CONCLUSIONS A nurse-led home injection service for somatuline autogel injections is associated with high adherence to treatment. Establishing such a program globally may lead to better adherence to treatment and improved disease control.

Abstract
Acromegaly is a systemic disease associated with increased morbidity and mortality. Most of these comorbidities can be prevented or delayed with adequate disease treatment. Although three modalities of treatment (surgery, medical treatment, and radiotherapy) are available and new drugs were approved in the last decades, there are still some patients that maintain disease activity despite treatment. Therefore, there is a need for novel therapies for acromegaly and for that purpose new formulations of currently used drugs and also new drugs are currently under study. In this review, we summarize the novel therapies for acromegaly.
