Long-term efficacy and safety of lerodalcibep in heterozygous familial hypercholesterolaemia: the LIBerate-HeFH trial.

BACKGROUND AND AIMS: Lerodalcibep, a novel small recombinant fusion protein of a proprotein convertase subtilisin/kexin type 9 gene-binding domain (adnectin) and human serum albumin, demonstrated highly effective low-density lipoprotein cholesterol (LDL-C) reduction with monthly 300 mg in 1.2 mL subcutaneous dosing in Phase 2. In this global Phase 3 trial, the safety and efficacy of lerodalcibep were evaluated in heterozygous familial hypercholesterolaemia patients requiring additional LDL-C lowering. METHODS: Patients were randomized 2:1 to monthly subcutaneous injections of either lerodalcibep 300 mg or placebo for 24 weeks. The primary efficacy endpoints were the per cent change from baseline in LDL-C at Week 24 and the mean of Weeks 22 and 24. RESULTS: In 478 randomized subjects [mean age (range); 53 (18-80) years, 51.7% female, mean (SD) baseline LDL-C 3.88 (1.66) mmol/L], lerodalcibep reduced LDL-C, compared with placebo by an absolute amount of 2.08 (0.11) mmol/L [LS mean (SE); 95% confidence interval -2.30 to -1.87] with a percentage difference of -58.61 (3.25)% at Week 24 and by 2.28 (0.10) mmol/L (95% confidence interval -2.47 to -2.09) with a percentage difference of -65.0 (2.87)% at the mean of Weeks 22 and 24 (P < .0001 for all). With lerodalcibep, 68% of subjects achieved both a reduction in LDL-C ≥ 50% and the recommended European Society of Cardiology LDL-C targets during the study. Except for mild injection site reactions, treatment-emergent adverse events were similar between lerodalcibep and placebo. CONCLUSIONS: Lerodalcibep, a novel anti-proprotein convertase subtilisin/kexin type 9 gene small binding protein dosed monthly as an alternative to monoclonal antibodies, significantly reduced LDL-C in subjects with heterozygous familial hypercholesterolaemia with a safety profile similar to placebo.

Inclusive management for social entrepreneurs with intellectual disabilities: "how they act".

BACKGROUND: Social entrepreneurship is a growing trend that reflects a shift in contemporary policy towards entrepreneurship and self-employment as viable employment option for people with disabilities. Entrepreneurship is intended to promote autonomy and reduce dependence on entitlement-based services as well as reduce employment disparities while stimulating business and job creation.However, it is not well understood what exactly this means for people with intellectual disabilities (ID) involved in social entrepreneurial ventures. METHODS: Dyadic interviews were conducted with people with ID participating in social entrepreneurship (n = 7) as well as with the person they identified as instrumental in providing support (n = 7). Interviews focused on understanding the management processes used by people with ID, or "how they act" in negotiating between formal and informal systems of services and supports and barriers encountered. RESULTS: Themes that emerged include the main barriers they experienced, how their businesses are organized; and the use of formal and informal services and supports. CONCLUSIONS: This research expands upon our understanding of social entrepreneurship and the management processes involved in customized employment for people with ID. It offers new insights and information for practitioners, policymakers, and researchers to inform the expectations we set for entrepreneurship as a sustainable employment option, from the perspective of social entrepreneurs with ID themselves.

Efficacy and Safety of Lerodalcibep in Patients With or at High Risk of Cardiovascular Disease: A Randomized Clinical Trial.

Importance: Recent changes in national and international lipid guidelines for reducing cardiovascular events recommend additional drugs, greater reductions, and lower targets for low-density lipoprotein cholesterol (LDL-C) if not attained with statins. The achievement of these targets with proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors has not yet been evaluated in a randomized clinical trial. Objective: To evaluate the 52-week safety and efficacy of lerodalcibep, a small anti-PCSK9-binding protein, in patients with cardiovascular disease (CVD) or who are at very high or high risk of CVD and requiring addition LDL-C-lowering treatment. Design, Setting, and Participants: This was a randomized, double-blind, placebo-controlled phase 3 trial. The trial was conducted at 66 clinics in 11 countries between April 23, 2021, and November 15, 2023. Individuals 18 years and older taking maximally tolerated statin therapy with LDL-C of 70 mg/dL or greater with CVD or 100 mg/dL or greater if at high risk of CVD were included. Interventions: Patients were randomized 2:1 to monthly 1.2-mL subcutaneous lerodalcibep, 300 mg, or placebo for 52 weeks. Main Outcomes and Measures: The safety analysis included all randomized patients. The co-primary efficacy end points were percent change from baseline in LDL-C at week 52 and the mean of weeks 50 and 52. Secondary efficacy outcomes included additional lipid apolipoprotein measures and achievement of guideline-recommended LDL-C targets. Results: Of 922 randomized participants (mean [range] age, 64.5 [27-87] years; 414 [44.9%] female; mean [SD] baseline LDL-C, 116.2 [43.5] mg/dL), 811 (88%) completed the trial. The mean (SE) placebo-adjusted reduction in LDL-C with lerodalcibep by modified intention-to-treat (mITT) analysis was 56.2% (2.2%) at week 52 and 62.7% (1.9%) for the mean of weeks 50 and 52; 49.7% (2.4%) and 55.3% (2.2%) by ITT with imputation using a washout model, and 60.3% (2.3%) and 65.9% (1.9%) by per-protocol analysis at week 52 and the mean of weeks 50 and 52, respectively (P < .001 for all). With lerodalcibep, 555 of 615 participants (90%) achieved both a reduction in LDL-C of 50% or greater and recommended LDL-C targets during the study. Treatment-emergent adverse events were similar between lerodalcibep and placebo, except for injection site reactions. These occurred in 42 of 613 participants receiving lerodalcibep (6.9%) compared to 1 of 307 receiving placebo (0.3%), were graded mild or moderate, and did not result in higher discontinuation of treatment, at 26 of 613 (4.2%) and 14 of 307 (4.6%), respectively. Sporadic in vitro antidrug antibodies were detected, which had no impact on free PCSK9 or LDL-C-lowering efficacy. Conclusions and Relevance: In this trial, lerodalcibep, a novel anti-PCSK9 small binding protein, dosed monthly and stable at ambient temperatures significantly reduced LDL-C in patients with CVD or at high risk of atherosclerotic cardiovascular disease with a safety profile similar to placebo. These results support long-term use of lerodalcibep in patients with CVD or at high risk of CVD who are unable to achieve adequate LDL-C reduction while receiving maximal tolerated statins alone.

Inclusive Entrepreneurship and Motivation Among People With Intellectual Disability: "Why They Act".

Social entrepreneurship is a growing trend for people with intellectual disability (ID). This trend reflects a shift in contemporary policy towards entrepreneurship and self-employment as a viable employment option for people with disability in general; a strategy which is intended to promote autonomy and reduce dependence on entitlement-based services as well as to reduce employment disparities and stimulate business and job creation. However, it is not well understood what exactly this means for people with ID involved in social entrepreneurial ventures. This research approached the issue by conducting dyadic interviews to explore the motivations of people with ID who are participating and supported in social entrepreneurship-"why they act." In exploring these motivations, this article investigates push-pull factors, the role of the social mission, and how support influences motivation.

Entrepreneurship by any other name: self-sufficiency versus innovation.

Entrepreneurship has been promoted as an innovative strategy to address the employment of people with disabilities. Research has predominantly focused on the self-sufficiency aspect without fully integrating entrepreneurship literature in the areas of theory, systems change, and demonstration projects. Subsequently there are gaps in services, policies, and research in this field that, in turn, have limited our understanding of the support needs and barriers or facilitators of entrepreneurs with disabilities. A thorough analysis of the literature in these areas led to the development of two core concepts that need to be addressed in integrating entrepreneurship into disability employment research and policy: clarity in operational definitions and better disability statistics and outcome measures. This article interrogates existing research and policy efforts in this regard to argue for a necessary shift in the field from focusing on entrepreneurship as self-sufficiency to understanding entrepreneurship as innovation.

The potential of social entrepreneurship: conceptual tools for applying citizenship theory to policy and practice.

Contemporary policy encourages self-employment and entrepreneurship as a vehicle for empowerment and self-sufficiency among people with disabilities. However, such encouragement raises important citizenship questions concerning the participation of people with intellectual and developmental disabilities (IDD). As an innovative strategy for addressing pressing social and economic problems, "social entrepreneurship" has become a phrase that is gaining momentum in the IDD community--one that carries with it a very distinct history. Although social entrepreneurship holds the potential to be an empowering source of job creation and social innovation, it also has the potential to be used to further disenfranchise this marginalized population. It is crucial that in moving forward society takes care not to perpetuate existing models of oppression, particularly in regard to the social and economic participation of people with IDD. The conceptual tools addressed in this article can inform the way that researchers, policymakers, and practitioners approach complex issues, such as social entrepreneurship, to improve communication among disciplines while retaining an integral focus on rights and social justice by framing this issue within citizenship theory.

A comparison of ICRU point doses and volumetric doses of organs at risk (OARs) in brachytherapy for cervical cancer.

INTRODUCTION: In brachytherapy for cervix cancer, doses to organs at risk (OARs) are traditionally calculated using the ICRU-38 point doses to rectum and bladder. Three-dimensional image-guided brachytherapy allows assessment of OAR dose with dose volume histograms (DVHs). The purpose of this study was to analyse the correlation between DVHs and ICRU point doses. METHODS: Using the PLATO™ planning system, the bladder, rectum and sigmoid were retrospectively contoured on 62 CT datasets for 20 patients treated with definitive radiotherapy. The median external beam radiotherapy dose was 45 Gy. Brachytherapy was delivered using a CT-MRI compatible tandem and ovoids to a median dose of 24 Gy in three fractions. DVHs were calculated, and the minimum dose to 2 cc of tissue receiving the highest dose (D(2cc) ) was recorded and compared with the ICRU point doses (D(ICRU) ). RESULTS: The mean rectal D(ICRU) was 4.01 Gy compared with D(2cc) of 4.28 Gy. The mean bladder D(ICRU) was 6.74 Gy compared with D(2cc) of 8.65 Gy. The mean sigmoid D(2cc) was 4.58 Gy. The mean dose ratios (D(2cc) /D(ICRU) ) were 1.08 for rectum and 1.39 for bladder. D(ICRU) correlated with D(2cc) for rectum (r = 0.76, P = 0.001) and for bladder (r = 0.78, P = 0.01). CONCLUSION: OAR doses assessed by DVH criteria were higher than ICRU point doses. The significant correlation between D(2cc) and D(ICRU) has allowed us to set DVH dose constraints for CT-based brachytherapy and thus begin the transition from two-dimensional to three-dimensional image-guided brachytherapy planning.

TENS and FES for sensory impairment and gait dysfunction following removal of spinal cord ependymoma--a case report.

BACKGROUND: Sensory deficits are commonly reported following the resection of spinal cord tumours. The use of transcutaneous electrical nerve stimulation (TENS) as augmented sensory input is described in the research literature but rarely in the clinical literature. Functional electrical stimulation (FES) is used for people with motor impairments rather than sensory impairments. METHOD AND RESULTS: This case report describes the use of TENS and FES for a patient with severe sensory loss and mild weakness in the right leg following the removal of an intramedullary spinal cord tumour. The patient was able to walk more quickly and more confidently when using TENS and FES in combination. She consistently reported greater benefits from TENS alone compared to FES alone and continued to use TENS delivered via a sock electrode at six months after surgery. CONCLUSION: The use of TENS as a sensory stimulus was an invaluable component of this patient's treatment, allowing her to engage in a more challenging balance and gait programme at an earlier stage in her rehabilitation. Combining FES with TENS was also useful and allowed treatment to address motor and sensory impairments concurrently during functional activity.
