Survey Outcome on Immunogenicity Risk Assessment Tools for Biotherapeutics: an Insight into Consensus on Methods, Application, and Utility in Drug Development.

A survey conducted by the Therapeutic Product Immunogenicity (TPI) community within the American Association of Pharmaceutical Scientists (AAPS) posed questions to the participants on their immunogenicity risk assessment strategies prior to clinical development. The survey was conducted in 2 phases spanning 5 years, and queried information about in silico algorithms and in vitro assay formats for immunogenicity risk assessments and how the data were used to inform early developability effort in discovery, chemistry, manufacturing and control (CMC), and non-clinical stages of development. The key findings representing the trends from a majority of the participants included the use of high throughput in silico algorithms, human immune cell-based assays, and proteomics based outputs, as well as specialized assays when therapeutic mechanism of action could impact risk assessment. Additional insights into the CMC-related risks could also be gathered with the same tools to inform future process development and de-risk critical quality attributes with uncertain and unknown risks. The use of the outputs beyond supporting early development activities was also noted with participants utilizing the risk assessments to drive their clinical strategy and streamline bioanalysis.

Immunogenicity Risk Assessment for Multi-specific Therapeutics.

The objective of this manuscript is to provide the reader with a hypothetical case study to present an immunogenicity risk assessment for a multi-specific therapeutic as part of Investigational New Drug (IND) application. In order to provide context for the bioanalytical strategies used to support the multi-specific therapeutic presented herein, the introduction focuses on known immunogenicity risk factors. The subsequent hypothetical case study applies these principles to a specific example HC-12, based loosely on anti-TNFα and anti-IL-17A bispecific molecules previously in development, structured as an example immunogenicity risk assessment for submission to health authorities. The risk of higher incidence and safety impact of anti-drug antibodies (ADA) due to large protein complexes is explored in the context of multi-specificity and multi-valency of the therapeutic in combination with the oligomeric forms of the targets.

Pediatric Endocrinology: Perspectives of Pediatric Endocrinologists Regarding Career Choice and Recruitment of Trainees.

OBJECTIVES: To examine main factors that influence the decision to choose pediatric endocrinology as a career among pediatric endocrinologists and assess their work satisfaction or stress level and suggested strategies to increase interest in subspecialty training in pediatric endocrinology. METHODS: A workforce survey was distributed among 1470 members of the Pediatric Endocrine Society. RESULTS: The response rate was 37.4%, with 550 members responding. The most common reasons for the respondents choosing pediatric endocrinology were intellectual stimulation (79%), exposure to endocrinology during residency (57%) or medical school (43%), and ability to establish relationships with patients with chronic disorders (54%). Of the respondents, 97% considered intellectual stimulation as the most favorable aspect of the specialty, and 84% considered financial compensation as the most unfavorable aspect of pediatric endocrinology. Majority (77%) were satisfied or very satisfied with their work environment. The mean work-related stress score (0 [none] to 10 [worst]) was 5.7, standard deviation was 2.1, and median was 6 (Q1, Q3: 4, 7). Increased financial compensation for the services and loan payment or forgiveness option were the top strategies suggested to enhance interest among residents for training in the subspecialty. One third (37%) felt that reducing the duration of the fellowship to 2 years would increase interest in training in pediatric endocrinology. CONCLUSION: The pediatric endocrinologists reported overall excellent career satisfaction, indicating the potential to attract high-quality doctors to the specialty. Improving reimbursement and loan forgiveness were the top strategies suggested for increasing interest in subspecialty training in pediatric endocrinology.

Current Perspectives on Management of Type 2 Diabetes in Youth.

The prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents is on the rise, and the increase in prevalence of this disorder parallels the modern epidemic of childhood obesity worldwide. T2DM affects primarily post-pubertal adolescents from ethnic/racial minorities and those from socioeconomically disadvantaged backgrounds. Youth with T2DM often have additional cardiovascular risk factors at diagnosis. T2DM in youth is more progressive in comparison to adult onset T2DM and shows lower rates of response to pharmacotherapy and more rapid development of diabetes-related complications. Lifestyle modifications and metformin are recommended as the first-line treatment for youth with T2DM in the absence of significant hyperglycemia. Assessment of pancreatic autoimmunity is recommended in all youth who appear to have T2DM. Pharmacotherapeutic options for youth with T2DM are limited at this time. Liraglutide, a GLP-1 agonist, was recently approved for T2DM in adolescents 10 years of age and older. Several clinical trials are currently underway with youth with T2DM with medications that are approved for T2DM in adults. Bariatric surgery is associated with excellent rates of remission of T2DM in adolescents with severe obesity and should be considered in selected adolescents.

Financial Distress Among Older Adults With Cancer.

PURPOSE: Financial distress (FD) among older adults with cancer is not well studied. We sought to characterize prevalence and factors associated with FD among older adults with cancer and the association of FD with geriatric assessment (GA) -identified deficits. PATIENTS AND METHODS: We included adults age ≥ 60 years with cancer in the University of Alabama at Birmingham Cancer and Aging Resilience Evaluation Registry who underwent GA during initial consultation with a medical oncologist before starting systemic therapy. We captured FD using a single-item question: "Do you have to pay for more medical care than you can afford?" We built multivariable models to study the impact of sociodemographic/clinical factors on FD as well as the association of FD with GA impairments. RESULTS: We identified 447 older adults with a median age of 69 years; 60% were men, 75% were White, and colorectal (26%) and pancreatic (19%) cancers were the most common. Overall, 27% (n = 121) reported having FD. Factors associated with FD included being Black (v White; odds ratio [OR], 2.26; 95% CI, 1.35 to 3.81; P = .002), being disabled/unemployed (v employed; OR, 2.60; 95% CI, 1.17 to 5.76; P = .019), and having an advanced degree (v less than high school; OR, 0.13; 95% CI, 0.03 to 0.65; P = .012). Patients with FD were more likely to report several GA impairments, including depression (OR, 2.10; 95% CI, 1.06 to 4.18; P = .034) and impaired health-related quality of life in physical (ß = -2.82; P = .014) and mental health domains (ß = -3.31; P = .002). CONCLUSION: More than a quarter of older adults with cancer reported FD at the time of initial presentation to an oncologist. Several demographic factors and GA impairments were associated with FD.

Review of Childhood Obesity: From Epidemiology, Etiology, and Comorbidities to Clinical Assessment and Treatment.

Childhood obesity has emerged as an important public health problem in the United States and other countries in the world. Currently 1 in 3 children in the United States is afflicted with overweight or obesity. The increasing prevalence of childhood obesity is associated with emergence of comorbidities previously considered to be "adult" diseases including type 2 diabetes mellitus, hypertension, nonalcoholic fatty liver disease, obstructive sleep apnea, and dyslipidemia. The most common cause of obesity in children is a positive energy balance due to caloric intake in excess of caloric expenditure combined with a genetic predisposition for weight gain. Most obese children do not have an underlying endocrine or single genetic cause for their weight gain. Evaluation of children with obesity is aimed at determining the cause of weight gain and assessing for comorbidities resulting from excess weight. Family-based lifestyle interventions, including dietary modifications and increased physical activity, are the cornerstone of weight management in children. A staged approach to pediatric weight management is recommended with consideration of the age of the child, severity of obesity, and presence of obesity-related comorbidities in determining the initial stage of treatment. Lifestyle interventions have shown only modest effect on weight loss, particularly in children with severe obesity. There is limited information on the efficacy and safety of medications for weight loss in children. Bariatric surgery has been found to be effective in decreasing excess weight and improving comorbidities in adolescents with severe obesity. However, there are limited data on the long-term efficacy and safety of bariatric surgery in adolescents. For this comprehensive review, the literature was scanned from 1994 to 2016 using PubMed using the following search terms: childhood obesity, pediatric obesity, childhood overweight, bariatric surgery, and adolescents.
