Abstract
OBJECTIVE Treatment of pediatric growth hormone deficiency (pGHD) with daily injection of recombinant human growth hormone (somatropin) aims to increase height velocity and improve health-related quality of life (HRQoL). The Quality of Life in Short Stature Youth (QoLISSY) questionnaire was administered in a phase 3 clinical trial that evaluated efficacy and safety of once-weekly somatrogon versus once-daily somatropin in children with pGHD (ClinicalTrials.gov no NCT02968004). METHODS Treatment-naïve prepubertal children with pGHD received once-weekly somatrogon or once-daily somatropin for 12 months. The QoLISSY core module (physical/social/emotional subscales) was administered at baseline and 12 months after treatment initiation. QoLISSY-Parent was completed by parents/caregivers of children <7 years old and some parents/caregivers of children ≥7 years old; children ≥7 years old self-completed QoLISSY-Child. RESULTS Baseline characteristics were similar between treatment groups (N = 117). Among children <7 years old, QoLISSY-Parent total and subscale scores showed similarly improved HRQoL at 12 months relative to baseline in both treatment groups. Self-reported QoLISSY-Child total and subscale scores in children ≥7 years old indicated HRQoL improvements at 12 months that were numerically better with somatrogon than somatropin (similar results with QoLISSY-Parent in this age group). At both time points, children reported better HRQoL than perceived by their parents/caregivers. CONCLUSION Treatment for 12 months with once-weekly somatrogon or once-daily somatropin resulted in comparable improvements in HRQoL among children with pGHD. Lower HRQoL perceived by parents/caregivers possibly reflect children's tendency to emphasize adaptation. These results suggest that evaluation of HRQoL could help support treatment decisions in children with pGHD treated with growth hormone.

Abstract
Introduction The standard of care for pediatric growth hormone deficiency (pGHD) is once-daily recombinant human growth hormone (rhGH). Somatrogon, a long-acting rhGH, requires less frequent, once-weekly, dosing. We describe physicians' preference for, experiences, and satisfaction with once-weekly somatrogon vs once-daily rhGH. Methods English-speaking investigators from somatrogon's global phase III study (NCT02968004) with prior experience using once-daily rhGH were included. Participants answered an online survey containing 14 closed- and open-ended items. Results Twenty-four pediatric endocrinologists (41.7% men; 79.2% practiced at public/private hospitals) from 12 countries with 25.8 ± 12.0 years' experience treating pGHD completed the survey. In terms of the time and effort required to explain device instructions, injection regimen, procedure for missed injection, and address patients'/caregivers' concerns, a similar proportion of physicians chose once-weekly somatrogon and once-daily rhGH; 62.5% physicians indicated that once-daily rhGH required greater effort to monitor adherence. Overall, 75% preferred once-weekly somatrogon over once-daily rhGH, 79.2% considered once-weekly somatrogon to be more convenient and less burdensome, and 83.3% were likely to prescribe somatrogon in the future. Overall, 50% felt that once-weekly somatrogon was more beneficial to patients, while 50% chose "No difference". Most physicians (62.5%) felt both regimens were equally likely to support positive long-term growth outcomes and reduce healthcare utilization. More physicians were "very satisfied" with once-weekly somatrogon (62.5%) than with once-daily rhGH (16.7%). Reduced injection frequency, patient and caregiver burden, increased convenience, and improved adherence were reasons for these choices. Conclusion Physicians had a positive experience with, and perception of, treating pGHD with once-weekly somatrogon.

Abstract
OBJECTIVES Paediatric growth hormone deficiency (pGHD) manifests as growth failure associated with inadequate growth hormone (GH) production. Daily injections of recombinant human GH (dGH) [somatropin] is the current standard of care, which has been shown to be well tolerated and effective, but associated with suboptimal adherence, leading to reduced effectiveness. Somatrogon, a once-weekly injectable long-acting human GH, has demonstrated clinical non-inferiority and significantly lower life interference (i.e. treatment burden) vs. somatropin in two Phase 3 studies. This work evaluated cost-effectiveness and cost-utility of somatrogon vs dGHs from an Irish payer perspective. METHODS A Markov model was developed for patients starting somatrogon or dGHs treatment at 3-12 years and continuing up to achievement of near adult height (NAH), with growth driven by trial-based height velocity (HV) and treatment-specific adherence. Patients could discontinue treatment at the end of Year 1 (4%). DGH adherence (95.3%-65% over treatment duration) and adherence-growth relationship were based on published evidence. Higher Year 1 adherence of 4%, tapering over time, for somatrogon vs. dGHs was based on clinical consultation. Treatment costs, monitoring costs and costs due to different wastage types (device setting and adherence) were sourced from local data. Health utilities based on height and injection frequency were derived from published literature. Scenario analysis, deterministic and probabilistic sensitivity analysis were performed. RESULTS Somatrogon treatment led to 1.87-3.66 cm greater NAH gain and 0.21-0.50 higher quality adjusted life years (QALYs) vs. dGHs, across the base case and scenarios evaluated. Somatrogon treatment was associated with cost savings of €5,699-€21,974 and lower cost per cm gained vs. dGHs (€197-€527), per patient. Somatrogon was cost-effective vs. dGHs, with the result consistent across the sensitivity analyses conducted. CONCLUSION Somatrogon weekly injections were estimated to result in higher NAH, higher QALYs, lower overall costs and lower costs per cm gained than dGHs, in pGHD.

Abstract
BACKGROUND Daily injections of recombinant human growth hormone are the standard of care to treat growth failure due to pediatric growth hormone deficiency (GHD). While effective, daily injections are burdensome and can compromise adherence. In recent years, novel injection treatments requiring less frequent administration for growth hormone deficiency (GHD) have been developed. A targeted, pragmatic literature review was conducted to summarize and document the patient experience of moving from daily to less frequent injections, with a specific focus on changing from daily to weekly injection treatments in pediatric GHD (pGHD). OBJECTIVE Explore and describe the patient experience when switching from a daily to a less frequent injection schedule for GHD. METHODS Targeted literature searches were conducted to identify literature describing the patient experience of moving from a daily to weekly injection in GHD. Supplementary searches were conducted to identify literature describing the patient experience of moving from daily to less frequent injection regimens in other medical conditions. RESULTS Across searches, 1,691 abstracts were reviewed and 13 articles were included in the final analysis. These publications reported that patients moving to less frequent injections across a variety of conditions, including GHD, experienced increased convenience and satisfaction, higher adherence rates, fewer adverse events, and improved quality of life. Less frequent injections were also reported to be at least as efficacious as daily treatments. CONCLUSIONS Less frequent injections in GHD and as other conditions are less burdensome, positively benefit patients, and result in improved adherence that may lead to improved clinical outcomes. Clinicians may consider weekly regimens as an effective alternative for patients, in particular in pGHD, especially when missed injections can negatively impact treatment outcomes. More research is needed to better understand the real-world benefits of injectable therapies that require less frequent administration (e.g., weekly versus daily).

Abstract
Abstract
Background
Somatrogon is a long-acting recombinant human growth hormone (hGH) currently being developed as a once-weekly subcutaneous injectable treatment for pediatric patients with growth hormone deficiency (GHD). A recent global Phase 3 study compared the efficacy and safety of somatrogon administered once weekly with Genotropin administered once daily in pediatric patients with GHD (ClinicalTrials.gov: NCT02968004).
Aims
To understand and describe physicians’ experiences using once-weekly somatrogon injections compared with once-daily hGH injections during the Phase 3 study.
Methods
In this quantitative, cross-sectional, observational study, a 14-item multiple choice questionnaire was administered to physicians who were clinical investigators in the Phase 3 study. The questionnaire was designed to assess physicians’ experiences, preferences and satisfaction regarding the use of the once-weekly somatrogon regimen compared with the standard once-daily hGH injection regimen. Survey results were analyzed quantitatively using descriptive statistics.
Results
A total of 24 physicians who were part of the global Phase 3 study (mean age [SD]: 58.5 [10.1] years; 10 males, 14 females) in 12 different countries completed the on-line survey. Compared with daily injections, most physicians preferred somatrogon (n=18, 75.0%) and reported that somatrogon was more convenient (n=19, 79.2%), less burdensome (n=19, 79.2%) and that they would be more likely to prescribe somatrogon to patients in the future (n=20, 83.3%). In terms of being more likely to support positive long-term growth outcomes, 37.5% (n=9) of physicians selected somatrogon; the remaining physicians (n=15, 62.5%) reported no difference between treatments. The proportion of physicians who were satisfied or very satisfied with somatrogon was 95.8% (n=23), compared with 87.5% (n=21) for daily hGH injections.
Most physicians (n=15, 62.5%) reported that daily hGH injections required more effort/much more effort to monitor adherence, compared with somatrogon. Some physicians (n=7, 29.2%) reported that explaining the device instructions to patient/caregivers required more/much more effort for somatrogon compared with daily hGH injections; more than half (n=14, 58.3%) reported no difference in effort required for either regimen. Physicians were divided as to which treatment needed more/much more effort to: (i) explain the injection regimen (n=7 [29.2%] daily injection; n=7 [29.2%] no difference; n=10 [41.7%] somatrogon), (ii) explain what to do if an injection is missed (n=7 [29.2%] daily injection; n=9 [37.5%] no difference; n=8 [33.3%] somatrogon), and (iii) address patient/caregiver questions (n=8 [33.3%] daily injection; n=11 [45.8%] no difference; n=5 [20.8%] somatrogon).
Conclusions
Overall, physicians from the global Phase 3 study were positive about their experience using somatrogon for the treatment of children with GHD. Physicians generally preferred the once-weekly somatrogon injection regimen, with most physicians reporting somatrogon to be more convenient and less burdensome to patients, indicating that they would be more likely to prescribe somatrogon to their patients in the future.

Abstract
Abstract
Background
Suboptimal adherence to, and persistence with, daily somatropin therapy to treat children with growth hormone deficiency (GHD) has been documented previously, and has also been shown to have negative effects on the growth response.
Objectives
To describe discontinuation of, and persistence to, daily somatropin treatment among pediatric patients with GHD in the UK.
Methods
This was a retrospective cohort study of pediatric patients (≥3 and <16 years) with >1 medication prescription for daily injectable somatropin from 1 st July 2000 to 31 st December 2020 in the IQVIA Medical Research DATA (IMRD) database. Patients were required to have >1 diagnostic code for GHD during the 6 months preceding and including the first somatropin prescription date ("index date"), and to be continuously enrolled in the database >6 months preceding and >3 months following index date. Patients with >1 somatropin prescription during the 6 months prior to index date, or with diagnoses for other causes of short stature were excluded. Patients were followed for up to 48 months post-index. Early persistence was defined as the proportion of patients prescribed ≥1 somatropin refill subsequent to the initial prescription. Discontinuation was defined as the first date at which a medication gap (defined as either >60 days or >90 days between prescriptions) for somatropin occurred. Persistence (non-discontinuation) over time was evaluated using Kaplan-Meier methods to assess time to first discontinuation event. The relationship of patient characteristics with time to medication discontinuation was evaluated using Cox proportional hazards models.
Results
Among pediatric patients included in this study (n=117), the majority (n=84, 71.8%) had 48 months of available follow-up; 56.4% were male and mean (median) age was 8.6 (8. 0) years. About 98% of patients exhibited early persistence. Persistence over the follow-up period decreased with follow-up duration. Using a 60-day gap definition, persistence at 12, 24, 36, and 48 months was estimated among 48.3%, 35.4%, 26.7%, 16.5% of patients; using a more conservative 90-day definition, an estimated 72.4%, 58.6%, 52.8%, and 43.3% were persistent at the same time periods. No significant patient predictors of time to discontinuation were identified.
Conclusions
Despite high early persistence with somatropin, a sizable proportion of patients were increasingly non-persistent over time. In this UK-based study more than 1 in 4 patients were non-persistent at 12 months and more than 1 in 2 were non-persistent at 48 months. These results suggest that strategies to support improved medication-taking behavior among pediatric patients with GHD in the UK are warranted.

Abstract
Context Somatrogon is a long-acting recombinant human growth hormone treatment developed as a once-weekly treatment for pediatric patients with growth hormone deficiency (GHD). Objective Evaluate patient and caregiver perceptions of the treatment burden associated with the once-weekly somatrogon injection regimen vs a once-daily Somatropin injection regimen. Methods Pediatric patients (≥3 to <18 years) with GHD receiving once-daily somatropin at enrollment were randomized 1:1 to Sequence 1 (12 weeks of once-daily Somatropin, then 12 weeks of once-weekly somatrogon) or Sequence 2 (12 weeks of once-weekly somatrogon, then 12 weeks of once-daily Somatropin). Treatment burden was assessed using validated questionnaires completed by patients and caregivers. The primary endpoint was the difference in mean overall life interference (LI) total scores after each 12-week treatment period (somatrogon vs Somatropin), as assessed by questionnaires. Results Of 87 patients randomized to Sequence 1 (n = 43) or 2 (n = 44), 85 completed the study. Once-weekly somatrogon had a significantly lower treatment burden than once-daily Somatropin, based on mean overall LI total scores after somatrogon (8.63) vs Somatropin (24.13) treatment (mean difference –15.49; 2-sided 95% CI –19.71, –11.27; P < .0001). Once-weekly somatrogon was associated with greater convenience, higher satisfaction with treatment experience, and less LI. The incidence of treatment-emergent adverse events (TEAEs) for Somatropin and somatrogon was 44.2% and 54.0%, respectively. No severe or serious AEs were reported. Conclusion In pediatric patients with GHD, once-weekly somatrogon had a lower treatment burden and was associated with a more favorable treatment experience than once-daily Somatropin.

Abstract
OBJECTIVE The objective of this retrospective cohort study was to describe the adherence and discontinuation patterns of somatropin over 3 years among children with pGHD insured by Medicaid across the United States. METHODS Eligible children were aged ≥3 and <16 years with Medicaid coverage, diagnosed with pGHD, and had ≥2 new prescriptions for somatropin between 1 July 2014 and 31 December 2018. Four non-exclusive patient cohorts were constructed (≥3, 12, 24, and 36 months of continuous enrollment after initial prescription). Suboptimal adherence was defined as medication possession ratio <0.80, and discontinuation as a gap of >60 days between somatropin fills. Logistic and proportional hazards regression methods were used to estimate odds of suboptimal adherence and time to discontinuation, respectively. RESULTS In the 12-month cohort (n = 3623), mean age was 10.5 ± 3.2 years, 70.8% were male, 44.4% White, 29.1% Hispanic, 7.1% Black, and 1.7% Asian. At months 12, 24, and 36, the proportion with suboptimal adherence was 40.9, 50.4, 54.4%, respectively, and 49.2% of patients with ≥3 months of follow-up discontinued therapy. At 12 months, lower age and race/ethnicity (Black vs. White referent) had greater odds of suboptimal adherence. Discontinuation was associated with Black (vs. White referent) race and geographic region. CONCLUSIONS Sociodemographic characteristics may be risk factors for suboptimal adherence and/or discontinuation of prescribed somatropin therapy. Improving GH regimen adherence among this at-risk population, and specifically among subgroups at highest risk, is warranted to improve clinical outcomes.

Abstract
PURPOSE To report the effects of pegvisomant (PEGV) treatment on patient-reported outcomes in acromegaly patients. METHODS We conducted an extension study of an open-label, multinational, non-interventional study (ACROSTUDY) evaluating the long-term safety and efficacy of PEGV for acromegaly in routine clinical practice. Enrolled patients were rollover patients from ACROSTUDY, or treatment naïve/semi-naïve (NSN; no PEGV within 6 months of enrollment). Exploratory efficacy endpoints were changes in symptoms with the Patient-Assessed Acromegaly Symptom Questionnaire (PASQ) and quality of life with the Acromegaly Quality of Life questionnaire (AcroQoL) analyzed by controlled or uncontrolled IGF-I levels. Results were analyzed in all patients, in NSN patient subgroup, and by diabetes status. RESULTS A total of 544 patients with acromegaly were enrolled, including 434 rollover subjects from ACROSTUDY and 110 NSN patients. Mean PEGV treatment duration was 7.8 years (range, 0-19.6 years). Overall, the majority of PASQ scores improved over time, but there was no significant difference between IGF-I controlled or uncontrolled groups. In the NSN subgroup, most PASQ and AcroQoL scores remained similar to baseline up to 1 year, regardless of IGF-I control. Patients with diabetes reported better PASQ scores over time with PEGV treatment, regardless of IGF-I control. IGF-I normalization increased from 10% of patients at baseline to more than 78% at year 10, with a mean daily PEGV dose of 18.7 mg. CONCLUSIONS Overall, patients treated with PEGV had small improvements in PASQ. While IGF-I normalization increased with PEGV treatment, IGF-I control had no effects on PASQ and AcroQoL scores.

Abstract
BACKGROUND Children with growth hormone deficiency (GHD) are treated with daily somatropin injections; however, poor treatment persistence and adherence have been recognized previously and have been shown to negatively impact growth outcomes. A recent real-world study of a US pediatric GHD population found that a substantial proportion of children discontinued somatropin therapy, but similar data for a real-world UK population are lacking. OBJECTIVES To describe the discontinuation of, and persistence with, daily somatropin treatment among children with GHD in the UK. METHODS This was a retrospective cohort study of children (≥3 and <16 years old) with ≥1 medication prescription for daily injectable somatropin from 1 July 2000 to 31 December 2020 in the IQVIA Medical Research DATA (IMRD) database. Early persistence was defined as the proportion of children prescribed ≥1 somatropin refill (≥2 prescriptions). Discontinuation was defined as the first date at which a medication gap for somatropin (of >60 or >90 days between prescriptions) occurred. Kaplan-Meier methods were used to evaluate persistence (non-discontinuation) over time to assess time to first discontinuation event. Cox proportional hazards models were used to evaluate the relationship between patient characteristics and time to medication discontinuation. RESULTS Among the cohort identified in this study (n = 117), the majority (n = 84, 71.8%) had 48 months of available follow-up; 56.4% were boys and the mean (median) age was 8.6 (8.0) years. About 98% exhibited early persistence, but persistence over the follow-up period decreased with follow-up duration. Using the conservative 90-day gap definition of persistence, an estimated 72.4%, 52.8%, and 43.3% were persistent at 12, 36, and 48 months. Lower persistence rates were observed using the 60-day definition. No significant patient predictors of time to discontinuation were identified. CONCLUSIONS Despite high early persistence with somatropin, a high percentage of children with GHD were increasingly non-persistent over time. More than 1 in 4 were non-persistent at 12 months and more than 1 in 2 were non-persistent at 48 months of follow-up. These results suggest that strategies to support improved medication-taking behavior among children with GHD in the UK are warranted.

Abstract
OBJECTIVE To evaluate adherence to, and discontinuation of, somatropin treatment over 4 years in a US population-based study of children with pediatric growth hormone deficiency (pGHD). METHODS A retrospective cohort analysis of commercially insured patients ≥3 and <16 years, diagnosed with pGHD, newly treated with somatropin was conducted using Optum De-identified Clinformatics Data Mart. Index date was defined as the first prescription for somatropin between 01 July 2002 and 30 September 2019. Five non-exclusive patient cohorts were identified (>3, 12, 24, 36, and 48 months of post-index continuous enrollment). Suboptimal adherence was defined as medication possession ratio <80%. Discontinuation was defined as the date at which a gap of >60 days between somatropin fills first occurred. Cox proportional hazards regression was used to evaluate time to discontinuation. RESULTS In the 12-month cohort (n = 3091), mean age was 11.3 ± 2.9 years, 75.9% were male, 70.9% white, 9.4% Hispanic, 3.6% Asian, and 3.1% black. The proportion with suboptimal adherence at months 12 and 48 was 19.6% and 35.9%, respectively. Discontinuation occurred in 42.2% of patients. The rate of discontinuation (HR [95% CI]) was higher for age ≥10 (1.74 [1.53-1.98]), females (1.35 [1.21-1.50]), black and Hispanic race/ethnicity (1.50 [1.18-1.90] and 1.27 [1.09-1.49] compared to White) and obesity (1.69 [1.19-2.40]). CONCLUSION Suboptimal adherence increases with treatment duration, and risk of discontinuation is associated with age, female gender, black or Hispanic race/ethnicity, and obesity. Strategies that facilitate adherence among children at risk of discontinuation may improve clinical outcomes.

Abstract
Objective: Paediatric growth hormone deficiency (pGHD) affects 1/4,000 children. Treatment with daily sub-cutaneous injections of recombinant human growth hormone (r-hGH) increase height velocity and quality of life (QoL). A recent randomised controlled clinical trial (NCT02968004) evaluated the efficacy/safety of weekly Somatrogon (hGH-CTP) and daily Genotropin in pGHD. QoL (an exploratory endpoint) was evaluated using the validated Quality of Life in Short Stature Youth (QoLISSY) questionnaire, which includes three subscales (physical, social, emotional) and total score. Methods: The QoLISSY core module was administered to patients (aged 3-11 years [girls], 3-12 years [boys]) and parents in US, UK, Australia, New Zealand, Belarus, Russia, Ukraine and Spain, at Baseline (BL) and 12 months after treatment start. The QoLISSY-CHILD was completed by children aged ≥7 years; QoLISSY-PARENT was completed by the Caregiver for children <7 years, and for some children aged ≥7 years. We report here only the QoLISSY results for children aged ≥7 years (reported from either child or parent). Results: For Total QoLISSY-PARENT, for children aged ≥7 years in the Somatrogon group (N=26), mean scores are 53.65 (BL) and 65.52 (month 12) with mean change of 13.01 (95% Confidence Interval [CI]: 3.99, 22.02). In the Genotropin group (N=28), mean scores are 55.89 (BL) and 63.66 (month 12) with mean change of 6.60 (CI:-0.21, 13.40). For Total QoLISSY-CHILD in the Somatrogon group (N=35), mean scores are 61.48 (BL) and 74.69 (month 12) with mean change of 13.00 (CI: 5.81, 20.19). In the Genotropin group (N=35), these scores are 60.96 (BL) and 69.03 (Month 12) with mean change of 7.84 (CI: 2.71, 12.97). Scores of >70 indicate a good QoL. Conclusions: QoL in children aged ≥7 years improved, following 12 months of either treatment, whether this was reported by caregiver or child. However, these data show that the baseline scores and 12 month scores from the QoLISSY-PARENT in both treatment groups were numerically lower than those reported by the child. This is consistent with the literature¹, in which the caregivers generally report lower QoL scores on behalf of the child. ¹Explaining parent-child (dis)agreement in generic and short stature-specific health-related quality of life reports: do family and social relationships matter?

Abstract
Introduction and Objective: Pediatric growth hormone deficiency (pGHD) occurs in approximately 1 in 4,000 children. The main manifestation is short stature managed with daily injections of somatropin, a recombinant human growth hormone (r-hGH). Prior research has shown that children with good adherence with r-hGH have significantly greater linear growth compared to those with sub-optimal adherence. While previous studies have found sub-optimal adherence with daily r-hGH injectables among children with pGHD, to date, r-hGH adherence has not been studied among large, usual-care populations using validated measurements of adherence. We describe adherence to somatropin treatment over 4 years in a population-based study. Materials and Methods: A retrospective cohort analysis of commercially insured patients ≥3 and <16 years, diagnosed with pGHD, newly treated with somatropin from 01 January 2002 through 31 December 2019 (study time period) was conducted using Optum De-identified Clinformatics Data Mart database. Index date was defined as the first prescription for somatropin between 01 July 2002 to 30 September 2019. Four patient cohorts were identified (12, 24, 36, and 48 months of post-index continuous enrollment). The demographic and clinical profiles of children with pGHD treated with daily injections of somatropin who have good adherence and those with sub-optimal adherence were characterized. Good adherence was defined as medication possession ratio (MPR) of ≥ 80%, sub-optimal adherence as MPR <80%. Logistic regression models will evaluate the relationship between demographic characteristics (age, gender, race/ethnicity) and adherence (good vs. sub-optimal). Results: Patient characteristics were similar across each cohort; in the 12-month cohort (n=3091), mean age was 11.34 ±2.89 years, 75.9% were male, 70.9% white, 9.4% Hispanic, 3.6% Asian, and 3.1% black. At 48 months, 1193 (38.6%) of the 12-month cohort remained for follow-up. At 12 months, 80.1% had good adherence and mean (95% CI) MPR was 0.89 (0.88-0.89) while mean (95% CI) MPR at 48 months was 0.82 (0.81-0.83). The proportion with good adherence at months 24, 36, and 48 were 70.2%, 65.6%, and 64.0%, respectively. Adherence was not associated with age or gender. Blacks and Hispanics consistently exhibited lower adherence. At 12 months, good adherence was observed among 85.7% of Asians, 80.0% of whites, 77.2% of Hispanics, and 76.0% of blacks; at 48 months, good adherence was observed among 73.9% of Asians, 65.4% of whites, 56.8% of blacks, and 55.2% of Hispanics. Logistic regression model results will be provided. Conclusion: Although the majority of children with pGHD demonstrated good adherence with a daily r-hGH regimen, sub-optimal adherence increases with treatment duration and is higher among black and Hispanic children. Strategies that facilitate good adherence to r-hGH may support improved clinical outcomes.

Abstract
Abstract
Background: Somatrogon is a long-acting recombinant human growth hormone (rhGH) comprised of the amino acid sequence of hGH and 3 copies of the carboxy-terminal peptide from human chorionic gonadotropin. Somatrogon is being developed as a once weekly subcutaneous (SC) injectable treatment for pediatric patients (pts) with GHD.
Aims: To evaluate patient and caregiver perceptions of the treatment burden associated with a once weekly somatrogon SC injection schedule compared with a once daily Genotropin SC injection schedule.
Methods: In this phase 3 (NCT03831880), open-label, crossover study, pediatric pts (3 to <18 years) with GHD on at least 3 months stable rhGH therapy were randomized 1:1 to receive treatment according to 1 of 2 sequences: Sequence #1, 12 weeks of Genotropin once daily followed by 12 weeks of somatrogon once weekly; Sequence #2, 12 weeks of somatrogon once weekly followed by 12 weeks of Genotropin once daily. The primary objective of the study was to evaluate treatment burden assessed as the difference between mean overall Life Interference (LI) total scores after each 12-week treatment period of weekly somatrogon and daily Genotropin. Secondary objectives further assessed treatment experience of pts and caregivers after each treatment period and their comparison of both treatments at the end of the study. A recently developed, validated dyad questionnaire (Turner-Bowker DM et al, 2020) was administered as an electronic Patient Reported Outcome to collect all assessments.
Results: Eighty-seven pts were randomized to Sequence #1 (n=43) or Sequence #2 (n=44) with 85 pts completing the study. Somatrogon administered as a once weekly injection had a lower (statistically significant) treatment burden than Genotropin administered as a once daily injection, based on the mean overall LI total scores after somatrogon (8.63) vs Genotropin (24.13) treatment (mean difference: -15.49; two-sided 95% CI: [-19.71, -11.27]; P <0.0001). Compared with once daily Genotropin, once weekly somatrogon was associated with greater convenience, higher satisfaction with treatment experience, and less life interference for the caregiver. A higher proportion of pts preferred once weekly somatrogon and demonstrated a greater intent to comply with treatment. The proportion of pts who experienced at least one treatment-emergent adverse event (TEAE) with Genotropin and somatrogon treatment were 44.2% and 54.0%, respectively. Injection site pain was the most common TEAE during the Genotropin (12.8%) and somatrogon (14.9%) treatment periods and was rated as mild in most cases. No severe or serious adverse events were reported.
Conclusions: In pediatric pts with GHD, compared with Genotropin administered once daily, somatrogon administered once weekly has a lower treatment burden as shown by less life interference, and is associated with a more favorable treatment experience.

Abstract
OBJECTIVE Non-Alcoholic fatty liver disease (NAFLD) is becoming the most common liver disease in Western populations. While obesity and metabolic abnormalities are highly frequent in bipolar disorders (BD), no studies have been performed to estimate the prevalence of NALFD in individuals with BD. The aim of our study is to estimate the prevalence of NAFLD and to identify the potential associated risk factors in a large sample of BD individuals. METHODS Between 2009 and 2019, 1969 BD individuals from the FACE-BD cohort were included. Individuals with liver diseases, Hepatitis B or C, and current alcohol use disorders were excluded from the analyses. A blood sample was drawn from participants. Screening of NAFLD was determined using fatty liver index (FLI). Individuals with FLI> 60 were considered as having NAFLD. RESULTS The prevalence of NAFDL in this sample was estimated at 28.4%. NAFLD was observed in 40% of men and 21% of women. NAFLD was independently associated with older age, male gender, sleep disturbances, and current use of atypical antipsychotics or anxiolytics. As expected, the prevalence of NALFD was also higher in individuals with overweight and in those with metabolic syndrome. CONCLUSIONS This study reinforces the view that individuals with BD are highly vulnerable to metabolic and cardiovascular diseases. The prevalence of NAFLD in individuals with BD was two times higher than the prevalence reported in the general population. The regular screening of the MetS in individuals with BD should be therefore complemented by the additional screening of NAFLD among these vulnerable individuals.

Abstract
BACKGROUND Valproate is associated with teratogenic and neurodevelopmental effects. Several agencies have restricted the conditions of its prescription in bipolar disorders (BD). We aimed to assess the evolution of valproate prescription and the clinical profile of BD women of childbearing age receiving valproate. METHODS Based on a large national cohort, we included all BD women 16-50 years old. Sociodemographic, clinical and pharmacological data were recorded. Logistic regression analyses were used to describe variables associated with valproate prescription. RESULTS Of the 1018 included women 16-50 years old, 26.9% were treated with valproate with a mean daily dosage of 968 mg. The prevalence of BD women using valproate was 32.6% before May 2015 and 17.3% after May 2015 (p<0.001), the date of French regulatory publication of restriction of valproate prescription. The multivariate analysis revealed that the inclusion period after May 2015 (OR=0.54, CI 95% 0.37-0.78, p=0.001), the age lower than 40 years (OR=0.65, CI 95% 0.43-0.98, p=0.040) and the number of lifetime mood episodes (OR=0.98, CI 95% 0.95-0.99, p=0.040) were the variables negatively associated with the use of valproate. LIMITATIONS Study could be underpowered to determine a clinical profile associated with valproate prescription. CONCLUSIONS The regulatory change in BD women of childbearing age had a significant impact on valproate prescription, even if the prescription rate remains high. Important efforts are needed to help clinicians and patients to improve quality of care in BD women of childbearing age.

Abstract
OBJECTIVES Bipolar Disorder (BD) is frequently comorbid with other psychiatric disorders. However, few studies systematically examine which disorders are more likely to occur pre- or post-BD onset. We examine the prevalence and Age At Onset (AAO) of psychiatric conditions in adults with BD. METHODS A structured clinical interview was used to assess lifetime history and AAO of alcohol and cannabis misuse, suicide attempts, anxiety and eating disorders in a French sample of euthymic patients with BD (n = 739). Regression analyses were used to test for statistically significant associations between rates and AAO of comorbidities in BD groups stratified by sex or subtype. RESULTS Prevalence of alcohol and cannabis misuse was associated with male sex and BD-I subtype; whilst most anxiety and eating disorders were associated with female sex. The AAO of most comorbid conditions preceded that of BD, except for panic disorder, agoraphobia and alcohol misuse. Few variations were observed in AAO of comorbidities according to groups. LIMITATIONS All assessments were retrospective, so estimates of prevalence rates and especially exact AAO of some comorbidities are at risk of recall bias. CONCLUSIONS Sex and BD subtype are associated with different rates of comorbid disorders. However, there were minimal between group differences in median AAO of comorbidities. By describing the chronological sequence of comorbidities in BD we were able to demonstrate that a minority of comorbidities typically occurred post-onset of BD. This is noteworthy as these disorders might be amenable to interventions aimed at early secondary prevention.

Abstract
INTRODUCTION The daily injection burden of recombinant human growth hormone (r-hGH) replacement therapy to treat growth hormone deficiency (GHD) may reduce compliance and limit treatment benefit. Research is needed to evaluate patient preferences for GHD injection regimen and device features. OBJECTIVE Quantitatively evaluate factors driving preferences for r-hGH injection regimen and device features among pediatric (3-17 years, and caregivers) and adult (≥25 years) patients with GHD using a discrete choice experiment (DCE) approach. METHODS The DCE was part of a broader, cross-sectional observational field study to develop clinical outcome assessments (COAs) that assess the experience of patients taking r-hGH injections. Following ethics approval, discrete choice data were collected through an online questionnaire from consented participants recruited from eight sites in the United States. Participants were presented with 20 choice tasks, each comprising different combinations of two profiles. Participants were then shown the same set of three hypothetical device and injection profiles (ie, storage, preparation, injection type device, maintenance, dose setting, injection schedule) and asked whether they would choose each profile over their current device and schedule. Choice-based conjoint analyses were used to estimate the marginal utilities and values for treatment attributes. Subject preferences were estimated at individual and aggregate levels. RESULTS Two hundred and twenty-four participants completed the DCE (n=75 adults, n=79 adolescent/caregiver dyads, n=70 child/caregiver dyads). Injection schedule was the strongest predictor of choice for the total sample and each patient group. Less frequent injection schedules were more likely to be chosen by participants. A "ready to use" injection was preferred, with no preference for auto-injector versus needle-free device. Most participants would choose the hypothetical injection devices and less frequent dosing over their current daily administered device schedule. CONCLUSION Patients prefer a less frequent injection regimen for treating GHD. Addressing patient preferences may improve compliance, adherence, and ultimately, clinical outcomes.

Abstract
BACKGROUND Quality of life (QoL) and health economic data are becoming increasingly important factors in healthcare decision making. While there is a wealth of information establishing the benefit of growth hormone (GH) replacement therapy in adults with growth hormone deficiency (aGHD), recent reviews on the QoL and health economic impact of aGHD and the effect of treatment on these factors is limited. OBJECTIVE The aim of this article is to summarize the impact of early and sustained treatment on the QoL and economic burden of aGHD by conducting a targeted literature review. METHODS Standard electronic databases, including PubMed and the Cochrane collaboration website, were searched for publications between January 2006 and July 2016 for evidence of the humanistic and economic burden of aGHD. Search terms included growth hormone deficiency, health-related quality of life, HRQoL, patient-reported outcomes, outcome assessment, well-being and adherence. RESULTS The literature search identified 732 initial hits and a final 14 publications were included. The analysis showed that the economic burden of aGHD is largely driven by the productivity losses associated with the disease. This is because most patients with aGHD are of working age and the QoL domains (memory & concentration and energy & vitality) most commonly affected by aGHD severely impair a person's ability to work and may limit their contribution to society. CONCLUSION Untreated aGHD can seriously affect patients' functioning. Early and continued treatment with GH replacement therapy could potentially improve the QoL and reduce the economic burden associated with aGHD. This review has limitations: only English language articles published since January 2006 were included and many of the studies were conducted in the Nordic countries; it is unclear how representative these studies are of the population as a whole. This was a literature review and not a systematic review, as it was thought to be unlikely that, in this rare disease, any additional publications would have been identified. Overall, this review reveals a paucity of data in this underserved population and points to research gaps which could be addressed with new studies.

Abstract
Introduction: There is a growing trend of using patient preference studies to help incorporate the patient perspective into clinical drug development, care management, and health-care decision-making. Collecting and interpreting patient preference data is integral to multi-stakeholder engagement, patient-centric drug development, and clinical care management. Operationally, challenges exist in understanding 'when' and 'how' to embark on patient preference studies. This review will provide a brief overview of stated-preference methods, discuss applications throughout the clinical drug development and care management, and highlight how preference studies serve as a powerful tool for quantifying patient experiences for better outcomes. Areas covered: We present case studies to complement the different applications of stated-preference methods in clinical drug development and care management. We discuss the applications of preference data to help inform evidence-based patient advocacy, clinical development strategy, operational feasibility, regulator benefit-risk assessments, health technology assessments, and clinical decision-making. Expert commentary: Patient preference studies can serve as a powerful tool to engage patients and their communities as well as quantify the patient voice across different stages of clinical drug development and care management to support patient-centric health-care decision-making. It is expected that the application of these strategies will quickly advance in the coming years.

Abstract
Background: ACROSTUDY is an open-label, non-interventional post-authorization safety study that began in 2004 to evaluate safety in at least 1000 acromegaly patients treated with the GH receptor antagonist pegvisomant (PEGV). This commitment was fulfilled in Jan 2013. ACROSTUDY was later amended to enroll an additional 110 patients that were naïve/semi-naive to PEGV treatment. Semi-naïve patients are defined as not having received PEGV therapy for at least 6 months prior to enrollment. Objectives: The primary objectives were to: 1) assess the long-term safety of PEGV in real world practice; 2) assess the effect of IGF-I normalization on treatment outcomes, including safety, glucose control and patient-reported outcomes (PROs). Patients & Methods: 110 patients with Acromegaly 53.6% male, 81.8% Caucasian, median age 42.4 years at diagnosis; median age 48.9 years at PEGV start. Patients were considered ‘IGF-I Controlled’ if the most temporally-related IGF-I measurement was normal for that laboratory. Safety data including adverse events and liver tests were collected. IGF-I and HbA1C were measured; PROs were evaluated using the Acromegaly Quality of Life Questionnaire (AcroQoL) and PatientAssessed Acromegaly Symptom Questionnaire (PASQ), stratified by IGF-I control. Results: No new safety signals were identified in this sub-study. IGF-I SDS >2 decreased from 87% of patients at baseline to 31% at year 2 at a mean dose(±SD) of 10.4(±7.45) mg/day; patients with IGF-I SDS <2 had a mean dose of 14.8(±6.7). Among IGF-I controlled patients, median (range) HbA1C levels were 5.8% (5.4-6.1) at baseline and 5.6% (4.5-7.2) at year 2; in IGF-I uncontrolled patients, HbA1C was 6.1% (4.9-6.6) at baseline and 6.3% (2.9-10.6) at year 2. Among IGF-I controlled patients, median (range) global AcroQoL scores were 54.6 (24-73) at baseline and 61.4 (13-86) at year 2; while in IGF-I uncontrolled patients, median global AcroQoL score was 59.7 (8-92) at baseline and 63.6 (25-76) at year 2. Among IGF-I controlled patients, median (range) total PASQ score was 20 (3-38) at baseline and 17.5 (1-40) at year 2; in IGF-I uncontrolled patients, median total PASQ score was 17 (0-44) at baseline and 14 (3-39) at year 2. A greater number of the six individual symptoms of the PASQ score showed a positive trend for improvement from baseline to year 2 in the IGF-I controlled patients than in the uncontrolled patients. Summary: In this real-life world international study, overall biochemical control (i.e. normal IGF-I) was achieved with pegvisomant in 64.3% patients by year 2. Improved IGF-I control was associated with improved HbA1C, QoL and symptoms of acromegaly. One limitation of the study was that the PEGV dose may not have been adequately titrated to achieve IGF-I normalization.

Abstract
OBJECTIVES: To estimate the health care resource use (HCRU) and costs for patients diagnosed with acromegaly, following treatment with either pegvisomant, a growth hormone receptor antagonist (GHRA); or a somatostatin analogue (SSA). METHODS: De-identified data from Optum’s ClinformaticsTM Data Mart (CDM), a US claims database, were used to retrospectively identify patients with acromegaly from January 2011 - June 2018 who were treated with the GHRA or an SSA. Propensity score matching (PSM) was used to address the small sample size of acromegaly patients and to ensure a direct comparison between the two treatment groups. PSM was fitted using a logistic regression model that included age, gender, total cost and Charlson Comorbidity Index (CCMI) score at index¹. Follow up (FU), HCRU (including Emergency Room [ER] costs, outpatient and inpatient costs) were compared. Average differences in change from baseline costs between the GHRA and SSA from the matched groups are shown with p-values obtained from a t-test. All costs are average across visits. RESULTS: Following PSM 91 patients were treated with GHRA and 269 patients were treated with SSAs. Mean ER costs were higher in the SSA vs GHRA group ($63 vs -$19, p=0.5646). On average outpatient visits were higher in the SSA vs GHRA group (2.88 and 2.82 respectively, p=0.8583); associated costs were higher ($1181 and $789 respectively p=0.3832). Regarding office visits and associated costs, these were also higher in the SSA group (Visit: 0.77 vs 0.74 and Cost: $1 vs -$7). The number of inpatient visits was equal (average =0.03) for both groups, with slightly higher costs in the GHRA group ($131 vs $161, p=0.9644). The drug cost and overall total cost of SSAs vs GHRA were significantly different ($2630 vs $6933, p<0.0001; $3681 vs $7561, p<0.0004 respectively). In the matched group, 18.7% of GHRA and 26.0% of SSA patients had new diabetes as comorbidity at FU. DISCUSSION: This analysis suggests that patients treated with SSAs generally utilize slightly more healthcare resources. In particular, outpatient costs were higher in SSA group compared to GHRA. Looking at the matched CCMI at FU, the value was higher (with more comorbidities) for the SSA group (63%) compared to the GHRA group (57%), with a trend that higher rates of new diabetes comorbidities occur in the SSA group. CONCLUSIONS: Although the drug cost and total cost of treating with SSAs is less than that for GHRA, these data analyses show that patients treated with SSAs generally have an increased trend in patient visits, and hence healthcare utilization costs; this could be a consideration when making treatment choices.

Abstract
BACKGROUND Growth prediction models (GPMs) exist to support clinical management of children treated with growth hormone (GH) for growth hormone deficiency (GHD), Turner syndrome (TS) and for short children born small for gestational age (SGA). Currently, no prediction system has been widely adopted. CONTENT The objective was to develop a stand-alone web-based system to enable the widespread use of an 'individualised growth response optimisation' (iGRO) tool across European endocrinology clinics. A modern platform was developed to ensure compatibility with IT systems and web browsers. Seventeen GPMs derived from the KIGS database were included and tested for accuracy. SUMMARY The iGRO system demonstrated prediction accuracy and IT compatibility. The observed discrepancies between actual and predicted height may support clinicians in investigating the reasons for deviations around the expected growth and optimise treatment. CONCLUSIONS This system has the potential for wide access in endocrinology clinics to support the clinical management of children treated with GH for these three indications.

Abstract
OBJECTIVE The aim of our study was to investigate, in bipolar patients, whether affect lability was associated with suicidal ideation incidence during 2-year follow-up, and which subtype of affect lability was associated with suicidal ideation. METHOD A total of 319 euthymic or mildly depressed bipolar outpatients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups according to the occurrence of suicidal ideation during a 2-year follow-up. Affect lability was assessed by the French version of the Affect Lability Scale. RESULTS Bipolar patients with high affect lability were more likely to report suicidal ideation during follow-up, even after adjustment for age, study level, rapid cycling, current depression level, anxiety disorder, and lifetime history SA (OR = 2.47; 95% CI [1.15-5.30], P = 0.01). The risk of suicidal ideation increased with the level of affect lability. More specifically, the propensity to switch from neutral to elation affect, from anxious to depressive affect (or inversely), and from neutral to anger affect predicted suicidal ideation. CONCLUSION Reducing affective lability could become a new therapeutic target of suicidal prevention in bipolar disorder.

Abstract
BACKGROUND Clinical features of attention deficit hyperactivity disorder can be frequently observed in cases with bipolar disorders and associated with greater severity of bipolar disorders. Although designed as a screening tool for attention deficit hyperactivity disorder, the Wender Utah Rating Scale could, given its factorial structure, be useful in investigating the early history of impulsive, inattentive or mood-related symptoms among patients with bipolar disorders. METHODS We rated the Wender Utah Rating Scale in 276 adult bipolar disorder cases and 228 healthy controls and tested its factorial structure and any associations with bipolar disorder phenomenology. RESULTS We confirmed a three-factor structure for the Wender Utah Rating Scale (' impulsivity/temper', ' inattentiveness' and ' mood/self-esteem'). Cases and controls differed significantly on Wender Utah Rating Scale total score and sub-scale scores ( p-values < 10-5). About 23% of bipolar disorder cases versus 5% of controls were classified as ' WURS positive' (odds ratio = 5.21 [2.73-9.95]). In bipolar disorders, higher Wender Utah Rating Scale score was associated with earlier age at onset, severity of suicidal behaviors and polysubstance misuse; multivariate analyses, controlling for age and gender, confirmed the associations with age at onset ( p = 0.001) and alcohol and substance misuse ( p = 0.001). CONCLUSION Adults with bipolar disorders who reported higher levels of childhood symptoms on the Wender Utah Rating Scale presented a more severe expression of bipolar disorders in terms of age at onset and comorbidity. The Wender Utah Rating Scale could be employed to screen for attention deficit hyperactivity disorder but also for ' at-risk behaviors' in adult bipolar disorder cases and possibly for prodromal signs of early onset in high-risk subjects.

Abstract
OBJECTIVE Poor quality of sleep is frequent in euthymic bipolar patients and conveys worse clinical outcomes. We investigated the features of euthymic bipolar patients associated with poor sleep quality, with a focus on the effect of childhood trauma. METHOD 493 euthymic patients with DSM-IV-defined bipolar disorders were recruited in FondaMental Advanced Centers of Expertize for Bipolar Disorders (FACE-BD) between 2009 and 2014. Clinical variables were recorded. Subjective sleep quality and history of childhood trauma were respectively measured by the Pittsburgh Sleep Quality Index (PSQI) and the Childhood Trauma Questionnaire (CTQ). RESULTS Poor sleepers were older, less professionally active, had significantly higher anxiety levels, took more anxiolytic drugs and did endorse more suicide attempts and suicidal ideas than good sleepers after adjusting for anxiety levels and age. Emotional abuse was associated with poor sleep quality after adjustment for BMI, age, professional activity, and bipolar disorders (BD) type (OR=1.83; 95% CI [1.30; 3.10]; p=0.02). However, this association was lost after adjustment for anxiety levels, anxiolytic treatment and suicide ideation/attempts. LIMITATIONS The main limitation was the type of sleep assessment, which only measured the subjective part of sleep complaints. CONCLUSION A history of emotional abuse might underlie sleep problems in many bipolar patients but anxiety seems to act as a confounding factor in this relationship. New studies are needed to elucidate the role of childhood maltreatment on poor sleep among bipolar patients.

Abstract
BACKGROUND The aim of our study was to investigate, in bipolar patients, the association between tobacco status (use and dependence) and history of suicide attempt, and to assess the possible role of inflammation as a missing link in the association between smoking status and history of suicide attempt. METHODS A total of 453 adult bipolar out-patients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups: 274 patients without past history of suicide attempt (non-SA), and 179 patients with a past history of suicide attempt (SA). Tobacco use and dependence, psychiatric and somatic comorbidities, history of childhood abuse, family history of suicide were assessed. Fasting blood tests yielded samples collected for the measurement of high sensitivity (hs-)CRP. RESULTS The risk of suicide attempt increased with smoking dependence. Notably, bipolar patients with a history of suicide attempt were three times more likely to have severe tobacco dependence, independently of confounding factors. However, we failed to find arguments promoting the hypothesis of inflammatory markers (through hs-CRP measure) in the link between tobacco dependence and suicidal behavior. CONCLUSIONS We found a significant association between severe tobacco dependence and history of suicide attempt, but not with level of CRP, independently of confusing factors. Longitudinal studies taken into account all these potential confusing factors are needed to confirm our results.

Abstract
OBJECTIVE Identifying bipolar patients at high-suicide risk is a major health issue. To improve their identification, we compared dimensional and neuropsychological profile of bipolar patients with or without history of suicide attempt, taking into account suicidal severity (i.e. admission to intensive ward). METHOD A total of 343 adult euthymic bipolar out-patients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into three subgroups: 214 patients without history of suicide attempt, 88 patients with past history of non-severe suicide attempt and 41 patients with past history of severe suicide attempt. General intellectual functioning, speed of information processing, verbal learning and memory, verbal fluency and executive functioning were assessed. RESULTS Severe suicide attempters had lower affective intensity and lability than non-severe attempters. Severe suicide attempters outperformed non-severe attempters for verbal learning and non-attempters for Stroop word reading part after adjustment for study centre, age, gender, educational level, antipsychotics use, depression score, anxious and addictive comorbidities. CONCLUSION Neuropsychological tasks commonly used to assess bipolar patients do not seem accurate to identify suicide attempters in euthymic patients. In the future, decision-making and emotional recognition tasks should be assessed. Moreover, clinical and neuropsychological profiles should be considered together to better define suicidal risk.

Abstract
AIMS To examine the relationship between visual acuity in each eye and Quality of Life (QoL) outcomes in people with diabetic macular oedema. METHODS Cross sectional retrospective analysis of data collected at baseline in 289 people entered into a randomized clinical trial with diabetic macular oedema which investigated the safety and efficacy of a vascular endothelial growth factor inhibitor, pegaptanib sodium. At the baseline visit, visual acuity was measured through refraction and using retro-illuminated modified Early Treatment Diabetic Retinopathy Study Log MAR charts, and patient health-related QoL was determined using the European Quality of Life EQ-5D-3L and the Visual Functioning Questionnaire-25 (NEI-VFQ25). A regression analysis with QoL score from each vision-related domain as the dependent variable was fitted using linear and quadratic terms of the better and worse eye, age, gender, adjusted for number of concurrent conditions, ethnicity and level of diabetes control. RESULTS For all vision-related QoL domains from NEI-VFQ25 and EQ-5D-3L except ocular pain, both visual acuity in the better-seeing and the worse-seeing eye gave a significant increase in correlation coefficient over that obtained from clinical and demographic data. The NEI-VFQ25 correlation was most closely associated with a weighted visual acuity measure of 0.75 in the better and 0.25 in the worse eye or 0.60 in the better and 0.40 in the worse eye. CONCLUSIONS We recommend that a weighted visual acuity measure from both eyes is considered in future diabetic macular oedema trials.

Abstract
BACKGROUND To evaluate the cost-effectiveness of growth hormone (GH) treatment (Genotropin®) compared with no GH treatment in adults with GH deficiency in a Swedish societal setting. METHODS A Markov-type cost-utility simulation model was constructed and used to simulate, for men and women, morbidity and mortality for GH-treated and -untreated individuals over a 20-year period. The calculations were performed using current available prices concerning morbidity-related healthcare costs and costs for Genotropin®. All costs and treatment effects were discounted at 3%. Costs were expressed in Euro (1€ = 9.03 SEK). GH-treated Swedish patients (n = 434) were identified from the KIMS database (Pfizer International Metabolic Database) and untreated patients (n = 2135) from the Swedish Cancer Registry and the Hospital Discharge Registry. RESULTS The results are reported as incremental cost per quality-adjusted life year (QALY) gained, including both direct and indirect costs for GH-treated versus untreated patients. The weighted sum of all subgroup incremental cost per QALY was €15,975 and €20,241 for men and women, respectively. Including indirect cost resulted in lower cost per QALY gained: €11,173 and €10,753 for men and women, respectively. Key drivers of the results were improvement in quality of life, increased survival, and intervention cost. CONCLUSIONS The incremental cost per QALY gained is moderate when compared with informal thresholds applied in Sweden. The simulations suggest that GH-treatment is cost-effective for both men and women at the €55,371 (SEK 500,000 - the informal Swedish cost-effectiveness threshold) per QALY threshold.

Abstract
BACKGROUND Response to growth hormone (GH) therapy may vary between individual patients. Therefore the use of GH in children should be closely monitored to avoid over, under, or ineffective treatment regimens. The treatment response can be evaluated using growth prediction models. In an effort to improve the accuracy of these prediction models, Ranke et al. (J Clin Endocrinol Metab 95(3):1229-37) proposed a novel 'data-driven' approach based on a quantitative analysis of a large cohort of patients from the Pfizer International Growth Database (KIGS) treated with Genotropin (human growth hormone). This model allows physicians to predict and evaluate the level of growth response and responsiveness for their patients so they can adapt treatment accordingly. By comparing the actually observed and the predicted growth response the ability of an individual to respond to GH (responsiveness) can be estimated and further treatment can be adapted accordingly OBJECTIVE To determine the potential population level reduction in the amount of GH used and impact on height outcome of using this data-driven approach to guide treatment decisions, compared to conventional, 'experience-based' GH treatment in prepubertal patients with growth hormone deficiency (GHD) or Turner syndrome (TS). METHODS A model was developed to study the height outcome and the total amount of GH used in the presence or absence of data-driven treatment decisions. The proportion of patients for whom height outcome could be improved or GH use could be reduced (i.e. for low compliance, high or low responder) was estimated using the KIGS cohort. The analysis assumed that this segmentation allows physicians to tailor dosage to the individual patient's needs or even to discontinue therapy when it is not effective. The analysis used a 4-year time horizon, with Germany as an example country, but results are extendable to other countries. Only the total amount of GH used was included, and effects were defined as the height outcome after 4 years. RESULTS The analysis estimated that an evidence-driven approach may reduce the total amount of GH utilized by 7.0 % over 4 years for the treatment of short stature in prepubertal patients with GHD and TS in Germany. Despite the reduction in drug use the average growth outcomes remained unaffected with the new treatment approach. Univariate and probabilistic sensitivity analyses showed that the results are robust. CONCLUSIONS Our analysis showed that using a data-driven approach to guide treatment decisions for children with GHD or TS is estimated to result in efficiencies in the amount of GH used, without reducing the average growth in the population.

Abstract
BACKGROUND Diabetic Macular Edema (DME) is a common cause of impaired vision and blindness amongst diabetics. If not detected and treated early, the resulting vision loss can lead to considerable health costs and decreased health-related quality of life (HRQoL). The aim of this study was to provide evidence of the psychometric properties of the National Eye Institute - Visual Functioning Questionnaire (VFQ-25) for use in a cohort of DME patients who participated in a clinical efficacy and safety trial of pegaptinib sodium (Macugen). METHODS A phase 2/3 randomised, double masked trial evaluated pegaptanib injection versus sham injection in patients with DME. The analysis was conducted using baseline HRQoL data of the VFQ-25 and the EQ-5D, on a modified intent-to-treat sample of 235 patients. These measures were administered by a trained interviewer by telephone in all but one of the study countries, where face-to-face interviews were conducted in the clinic. The measures were completed in the week prior to baseline, and after 54 weeks of treatment. Distance visual acuity, measured according to the Early Treatment Diabetic Retinopathy Study (ETDRS), was assessed at all time points. Psychometric properties of the VFQ-25 assessed included domain structure, reliability, concurrent and construct validity, responsiveness. RESULTS The VFQ-25 was found to consist of 11 domains slightly different than those proposed. Nevertheless, none of the eight established multi-item scales met the criterion for further splitting and the VFQ-25 was scored as in the developers' instructions. Internal consistency reliability was demonstrated for six out of the eight original multi-item scales, with Cronbach's alpha ranging from 0.58 (Distance Activities) to 0.85 (Vision Specific: Dependency). The VFQ-25 domains generally showed a low to moderate correlation with EQ-5D visual analogue scale (range 0.16-0.43) and with the visual acuity score (range 0.10-0.41). Construct validity was upheld with higher VFQ-25 scores for patients who saw more letters according to the ETDRS. Almost all scales were shown to be responsive with Guyatt's statistic ranging from 0.10 to 0.56 at 54 weeks. CONCLUSIONS The VFQ-25 has evidence to support its validity and reliability for measuring HRQoL in DME. However, some operating characteristics of the instrument need further consideration and discussion in the case of DME patients. Further research is therefore warranted in this indication.

Abstract
BACKGROUND/AIMS The study aim was to develop and validate models for long-term prediction of growth in prepubertal children with idiopathic growth hormone deficiency (GHD) or Turner syndrome (TS) for optimal, cost-effective growth hormone (GH) therapy. METHODS Height was predicted by sequential application of annual prediction algorithms for height velocity in cohorts of GHD (n = 664) and TS (n = 607) as documented within KIGS (Pfizer International Growth Database). As height prediction models also require an estimate of weight, new algorithms for weight increase during the first to fourth prepubertal years on GH were developed. RESULTS When height was predicted from the start of GH treatment, the predicted and observed mean (SD) gain over 4 years was 30.4 (3.4) cm and 30.1 (4.9) cm, respectively, in GHD patients, and 27.2 (2.2) cm and 26.6 (3.5) cm, respectively, in TS patients. For all 4 years, gains of weight SD scores (SDS) were accurately described as a function of weight SDS and observed gain in height SDS (R(2) > 0.89). CONCLUSION In GHD and TS patients treated with GH, an accurate prepubertal long-term prediction of height development in groups is possible. Based on this, an optimal individual height outcome could be simulated.

Abstract
PURPOSE To confirm the safety and compare the efficacy of intravitreal pegaptanib sodium 0.3 mg versus sham injections in subjects with diabetic macular edema (DME) involving the center of the macula associated with vision loss not due to ischemia. DESIGN Randomized (1:1), sham-controlled, multicenter, parallel-group trial. PARTICIPANTS Subjects with DME. INTERVENTION Subjects received pegaptanib 0.3 mg or sham injections every 6 weeks in year 1 (total = 9 injections) and could receive focal/grid photocoagulation beginning at week 18. During year 2, subjects received injections as often as every 6 weeks per prespecified criteria. MAIN OUTCOME MEASURES The primary efficacy endpoint was the proportion gaining ≥ 10 letters of visual acuity (VA) from baseline to year 1. Safety was monitored throughout. RESULTS In all, 260 (pegaptanib, n = 133; sham, n = 127) and 207 (pegaptanib, n = 107; sham, n = 100) subjects were included in years 1 and 2 intent-to-treat analyses, respectively. A total of 49 of the 133 (36.8%) subjects from the pegaptanib group and 25 of the 127 (19.7%) from the sham group experienced a VA improvement of ≥ 10 letters at week 54 compared with baseline (odds ratio [OR], 2.38; 95% confidence interval, 1.32-4.30; P = 0.0047). For pegaptanib-treated subjects, change in mean VA from baseline by visit was superior (P<0.05) to sham at weeks 6, 24, 30, 36, 42, 54, 78, 84, 90, 96, and 102. At week 102, pegaptanib-treated subjects gained, on average, 6.1 letters versus 1.3 letters for sham (P<0.01). Fewer pegaptanib- than sham-treated subjects received focal/grid laser treatment (week 54, 31/133 [23.3%] vs 53/127 [41.7%], respectively, P = 0.002; week 102, 27/107 [25.2%] vs 45/100 [45.0%], respectively, P = 0.003). The pegaptanib treatment group showed significantly better results on the National Eye Institute-Visual Functioning Questionnaire than sham for subscales important in this population. Pegaptanib was well tolerated; the frequencies of discontinuations, adverse events, treatment-related adverse events, and serious adverse events were comparable in the pegaptanib and sham groups. CONCLUSIONS Patients with DME derive clinical benefit from treatment with the selective vascular endothelial growth factor antagonist pegaptanib 0.3 mg. These findings indicate that intravitreal pegaptanib is effective in the treatment of DME and, taken together with prior study data, support a positive safety profile in this population.

Abstract
Genotropin (somatropin) is licensed for the treatment of children with growth hormone deficiency, Prader-Willi syndrome, Turner syndrome, chronic renal insufficiency and in children born small for gestational age. This systematic review (SR) evaluated the clinical efficacy and effectiveness of Genotropin in these conditions to inform a NICE Technology Appraisal of growth hormone for the treatment of growth failure in children. Search terms were used to search seven databases, including Medline and Embase, for English language studies. Randomised controlled trials (RCTs) or observational studies investigating Genotropin in children were included. Out of 30 RCTs identified, one reported final height data. Eleven observational studies reported final height and seven were based on the Pfizer International Growth Survey (KIGS). This SR highlights the lack of long-term RCTs reporting final height data and other important qualitative outcomes, such as quality of life. Observational data, such as those from KIGS, remain vital for informing therapy.

Abstract
OBJECTIVES Primary open-angle glaucoma (POAG) is a chronic condition characterised by optic neuropathy and vision loss. Elevated intraocular pressure (IOP) can damage the optic nerve and is a risk factor for glaucoma, thus treatment usually comprises topical hypotensives. This analysis aims to address methodological issues associated with the synthesis of glaucoma clinical trial data, given variations in study methodology and IOP measurement. METHODS Meta-regression was used to estimate how IOP varies over time for patients receiving treatment. Relative treatment effects were assessed using a random-effects mixed treatment comparison (MTC) in order to preserve randomisation and avoid selection bias. To produce clinically meaningful outputs, these analyses were combined to obtain the mean on-treatment IOP and the proportion of patients achieving different IOP targets at different time points. A further MTC estimated the probability of hyperaemia events. RESULTS The analysis showed that after 3 months' treatment, between 58 and 83% of patients will have a > or =20% reduction in IOP and 70-93% of patients will have an absolute IOP <20 mmHg. Latanoprost and bimatoprost were found to produce significantly lower on-treatment IOP compared with timolol (p < 0.05); the difference between latanoprost and bimatoprost was not significant. Travoprost produced a lower mean IOP compared with timolol (not significant). Latanoprost-timolol was found to produce significantly lower IOP than latanoprost alone or beta-blockers. The probability of hyperaemia-type events varied between treatments from 14.8 to 63.03%. Latanoprost had significantly lower odds of hyperaemia than travoprost, bimatoprost, travoprost-timolol, or bimatoprost-timolol. CONCLUSION This analysis suggests that latanoprost and bimatoprost produce a statistically significant reduction in IOP compared with timolol, but are associated with a higher risk of hyperaemia. Out of all the prostaglandins, latanoprost may achieve a good balance between tolerability and IOP efficacy. As with all forms of meta-analysis, the results are based on the assumption that the studies and intervention groupings are sufficiently similar to be compared.

Abstract
BACKGROUND/AIMS Quantitative data regarding the impact of neovascular age-related macular degeneration (NV-AMD) on individuals and society is a prerequisite for rational decision-making processes when evaluating alternative treatments for the disease. METHODS 75 bilateral NV-AMD (patients) and 91 elderly non-AMD (controls) subjects forming the UK cohort of an international cross-sectional, observational study were independently analysed. Subjects completed a telephone survey including the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), the EuroQol (EQ-5D), the Hospital Anxiety and Depression Scale (HADS), history of falls and health resource utilisation. RESULTS Patients with NV-AMD reported substantially worse vision-related functioning and overall well-being, including higher depression scores, than controls after adjusting for age, gender and co-morbidities (adjusted mean scores: NEI-VFQ-25 overall 52.7 vs 90.7, p<0.0001; EQ-5D 0.67 vs 0.77, p = 0.0273; HADS depression 6.8 vs 4.0, p = 0.0026). Significantly more patients reported a need for assistance with daily activities compared with controls (25.3% vs 6.6%, p = 0.003). Total annual healthcare utilisation costs were more than sevenfold higher for patients with AMD compared with controls ( pound 3,823.89 vs pound 517.05, respectively; p<0.0001) CONCLUSIONS Patients with NV-AMD show a significant decline in quality of life and increased need for daily living assistance compared to a control population without AMD. With the availability of effective new therapies there is a need for improved early access to treatment.

Abstract
Two randomised, double-blind, parallel-group, placebo-controlled clinical trials were conducted to assess the efficacy of sumatriptan tablets, 50mg and 100mg, for treatment during the mild-pain phase of a menstrually associated migraine among patients who typically experienced moderate to severe migraine preceded by an identifiable phase of mild pain. Subjects (n = 403 in Study 1 and n = 349 in Study 2) treated one menstrually associated migraine on an outpatient basis. The results demonstrate that sumatriptan tablets, 50 mg or 100 mg, were significantly more effective than placebo at conferring pain-free response 1 h and 2 h post-dose; migraine-free response (i.e. no pain and no associated symptoms) 2 h post-dose; returning patients to normal functioning 2 h post-dose; and conferring sustained freedom from pain from 2 through 24 h post-dose. Although the studies were not designed or statistically powered to show differences between the sumatriptan doses, a trend for slightly higher efficacy was observed for the 100-mg dose compared with the 50-mg dose on many measures. Both doses of sumatriptan were well-tolerated. The only adverse events reported in more than 2% of subjects in a treatment group were nausea, paresthesia, dizziness and malaise/fatigue, all of which were reported at incidences comparable to or slightly higher than those with placebo. Considered in the context of other findings, these data suggest that--with menstrually associated migraine as with non-menstrual migraine--optimal therapeutic benefit of sumatriptan tablets may be realised when they are administered during the mild-pain phase of an attack rather than delaying treatment until headache is moderate or severe.

Abstract
This review considers the epidemiology, clinical manifestations and functional consequences of migraine in children and adolescents and surveys the studies establishing the efficacy and tolerability of sumatriptan nasal spray in this patient population. Although therapeutic advances in paediatric and adolescent migraine have lagged behind those in adult migraine, the first systematic studies of migraine medications in young patients have brought about progress in the past five years. These studies show that therapeutic approaches suitable for adult patients are not always applicable to paediatric and adolescent patients. Because of the unique characteristics of paediatric and adolescent migraine, it has been difficult to demonstrate in young patients the efficacy of oral sumatriptan and other triptan tablets, which are the medications of choice for adult migraine. With sumatriptan, this finding has proven to be a consequence of the form in which the drug was administered rather than the inherent properties of the drug. The availability of sumatriptan nasal spray allows the benefits of migraine-specific therapy to be extended to children and adolescents. In both well-controlled, single-episode studies and long-term, multiple-episode studies, sumatriptan nasal spray has been effective and well tolerated for the acute treatment of migraine in children and adolescents. Except for unpleasant taste, which is not significantly distressing to patients, sumatriptan nasal spray has a tolerability profile similar to thatof placebo in young patients.

Abstract
BACKGROUND Schizophrenia is a complex genetic disorder with no clear pattern of inheritance. Epigenetic modification of genes may thus play a role in its transmission. METHODS In our study, 439 families with at least two ill siblings with schizophrenia (208 with unilineal transmission) were examined for evidence of a parent-of-origin effect (e.g., evidence of parental imprinting on the familial transmission of schizophrenia). RESULTS No significant difference in the prevalence of maternal compared with paternal transmission was found. In addition, affected male subjects did not differ from affected female subjects in the proportion of their offspring diagnosed with schizophrenia. CONCLUSIONS Although the transmission of schizophrenia may be influenced by epigenetic events, our study fails to find evidence that one epigenetic mechanism, a parent-of-origin imprinting effect, determines whether an individual expresses the illness.

Abstract
BACKGROUND Since their introduction as diagnostic criteria by Schneider in 1937, nuclear symptoms have played a key role in concepts of schizophrenia, but their relationship to each other and to genetic predisposition has been unclear. AIMS To ascertain the factor structure and familiality of nuclear symptoms. METHODS Nuclear (Schneiderian) symptoms were extracted from case notes and interviews in a study of 103 sibling pairs with DSM-III-R schizophrenia or schizoaffective disorder. RESULTS Principal components analysis demonstrated two major factors: one, accounting for about 50% of the variance, groups thought withdrawal, insertion and broadcasting, with delusions of control; and the second, accounting for < 20% of the variance, groups together third-person voices, thought echo and running commentary. Factor I was significantly correlated within sibling pairs. CONCLUSIONS The correlation within sibling pairs suggests that, contrary to the conclusion of some previous studies, some nuclear symptoms do show a degree of familiality and therefore perhaps heritability.

Abstract
The hypothesis that a gene for susceptibility to psychosis (specifically in the X-Y homologous class) is located on the sex chromosomes has been proposed. Such a gene would account for the excess of sex chromosome anomalous males and females in populations of patients with psychosis, a tendency towards concordance by sex within families, and sex differences associated with psychosis and its underlying brain pathology. In earlier studies we observed small positive LOD scores in Xp11, and in a more recent and larger cohort of 178 sibling pairs, a peak multipoint nonparametric LOD score of 1. 55 at the locus DXS8032 in Xq21. The present study with a new set of markers extended the cohort to 301 ill sibling pairs and their parents. Despite the increase in sample size, the LOD score did not increase. A peak NPL of 1.55 was observed at the locus DXS1068 in proximal Xp, a region remote from the previous report. Separating families into those who were more likely to have X chromosome inheritance (maternal with no male to male transmission) did not yield stronger findings. In spite of the evidence that psychosis is related to a sex-dependent dimension of cerebral asymmetry, it is concluded that no consistent linkage of schizophrenia to the X chromosome can be demonstrated. In the context of the general failure of replication of linkage in psychosis, the possibility that the genetic predisposition to psychosis is contributed to by epigenetic modification rather than variations in the nucleotide sequence has to be considered.
