IQ Survey Results on Current Industry Practices: Part 2-Quantitative Evaluations of Immunogenicity Assessment.

All biotherapeutics have the potential to induce an immunogenic response and generate anti-drug antibodies (ADAs), especially when administered as multiple doses over prolonged periods. However, a clinically meaningful effect of ADAs can be difficult to identify to communicate the impact of immunogenicity on drug exposure, safety and efficacy outcomes in product labels in a way that is useful for health care providers. The immunogenicity working Group, IQ Consortium (Clinical Pharmacology Leadership Group) has conducted a survey to understand the current practices in analyzing immunogenicity data generated during clinical development and its impact on pharmacokinetics, clinically relevant pharmacodynamic biomarkers, safety, and efficacy outcome measures.

Quantifying natural amyloid plaque accumulation in the continuum of Alzheimer's disease using ADNI.

Brain amyloid beta neuritic plaque accumulation is associated with an increased risk of progression to Alzheimer's disease (AD) [Pfeil, J., et al. in Neurobiol Aging 106: 119-129, 2021].

Chapter 7: The different forms of primary hyperparathyroidism at different ages of life: Childhood, pregnancy, lactation, old age.

Primary hyperparathyroidism is rare in children. A germline mutation is identified in half of all children with primary hyperparathyroidism (70% of newborns and infants, and 40% of children and adolescents). The clinical manifestations of primary hyperparathyroidism in children are highly variable (often absent in newborns, rather severe and symptomatic in children and adolescents) and depend on the genetic cause, as well as the severity, rapidity of onset and duration of hypercalcemia.

A phase Ib/II study of galunisertib in combination with nivolumab in solid tumors and non-small cell lung cancer.

Background: In this phase Ib/II open-label study, tumor immune suppression was targeted in patients with advanced refractory solid tumors and patients with recurrent/refractory non-small cell lung cancer (NSCLC) using galunisertib with nivolumab.

Methods: Eligible patients were ≥ 18 years old, had an Eastern Cooperative Oncology Group performance status ≤ 1, and were treatment-naive for anti-programmed cell death-1, its ligand, or transforming growth factor β receptor 1 kinase inhibitors. Phase Ib was an open-label, dose-escalation assessment of the safety and tolerability of galunisertib with nivolumab in patients with advanced refractory solid tumors.

Young XLH Patients-Reported Experience with a Supportive Care Program.

Purpose: X-linked hypophosphatemia (XLH) is a rare, chronic, genetic condition characterized by renal phosphate wasting and abnormal bone and teeth mineralization. It represents a challenging and multifaceted disease that causes wide-ranging impacts on patients' lives. In this context, a scientific committee has designed a support initiative for patients treated for XLH: the aXess program.

A novel gene mutation in patients with isolated ACTH deficiency from distinct families with a common geographical origin.

Isolated ACTH deficiency (IAD) is a life-threatening condition, particularly in the neonatal period, while a main consequence of undiagnosed isolated ACTH deficiency in survivors is cognitive impairment. is involved in the differentiation and proliferation of corticotropic cells and mutations are responsible for more than 60% of neonatal cases of IAD. We describe a new variant of the main transcript (NM 005149.

Barriers to Physical Activity in Children and Adults Living With Type 1 Diabetes: A Complex Link With Real-life Glycemic Excursions.

Objectives: Ever since the first research on barriers to physical activity (PA) highlighting fear of hypoglycemia as a major barrier, many studies have attempted to understand their demographic and behavioural determinants. However, no research has been conducted on whether these perceived barriers toward PA are based on real-life-experienced adverse glycemic effects of exercise.

Methods: Sixty-two adults and 53 children/adolescents living with type 1 diabetes, along with their parents, completed the Barriers to Physical Activity in Type 1 Diabetes-1 (BAPAD-1) questionnaire on barriers to PA.

P019 Not All Fecal Calprotectin is Specific for Inflammatory Bowel Disease.

Case: Introduction:Fecal calprotectin is a known inflammatory marker used to evaluate patients with Inflammatory Bowel Disease (IBD). In fact, ACG Clinical Guideline for management of Crohn's disease recommend fecal calprotectin (FC) as a helpful test to distinguish IBD versus functional disorder such as Irritable Bowel Syndrome. Studies have also shown association of fecal calprotectin with colon cancer.

X-linked hypophosphatemia and burosumab: Practical clinical points from the French experience.

Hereditary hypophosphatemia with increased FGF23 levels are rare inherited metabolic diseases characterized by low serum phosphate because of impaired renal tubular phosphate reabsorption. The most common form is X-linked hypophosphatemia (XLH), secondary to a mutation in the PHEX gene. In children, XLH is often manifested by rickets, delayed development of gait, lower limb deformities, growth retardation, craniosynostosis, and spontaneous dental abscesses.

Phase 1b study of galunisertib and ramucirumab in patients with advanced hepatocellular carcinoma.

Background: Preclinical data suggest that vascular endothelial growth factor (VEGF) and transforming growth factor (TGF)-β signaling interact to stimulate angiogenesis and suppress antitumor immune responses. Thus, combined inhibition of both pathways may offer greater antitumor activity compared with VEGF-targeted antiangiogenic monotherapy against hepatocellular carcinoma (HCC).

Methods: This is a multicenter, open-label, phase 1b study of galunisertib, an inhibitor of TGF-β receptor 1, and ramucirumab, an anti-VEGF receptor 2 antibody, in patients with advanced HCC aiming to define the maximum tolerated dose (MTD).

Dramatic impact of morbid obesity on child lung development.

Objective: To assess the respiratory function and sleep characteristics of obese adults and children.

Methods: All patients with non-syndromic, severe obesity (BMI ≥3 z-scores for children and ≥40.00kg/m for adults), referred for pulmonary function tests at Lille University Hospital, were retrospectively included.

Safety and activity of the TGFβ receptor I kinase inhibitor galunisertib plus the anti-PD-L1 antibody durvalumab in metastatic pancreatic cancer.

Background: We assessed the safety, efficacy, and pharmacokinetics of the transforming growth factor beta (TGFβ) receptor inhibitor galunisertib co-administered with the anti-programmed death-ligand 1 (PD-L1) antibody durvalumab in recurrent/refractory metastatic pancreatic cancer previously treated with ≤2 systemic regimens.

Methods: This was a two-part, single-arm, multinational, phase Ib study. In a dose-finding phase, escalating oral doses of galunisertib were co-administered on days 1-14 with fixed-dose intravenous durvalumab 1500 mg on day 1 every 4 weeks (Q4W), followed by an expansion cohort phase.

Investigating the impact of target lesion selection on drug effect evaluation and tumour growth rate determination using tumour growth inhibition models: Example of malignant pleural mesothelioma patients treated with cisplatin alone or in combination with pemetrexed.

In the last update of the RECIST criteria in 2009, it was proposed that the number of target lesions to be followed over time for response-to-treatment assessment be reduced from 10 to 5 lesions maximum, with up to 2 per organ. We explored the impact of reducing the number of target lesion on the assessment of drug effect in a randomised phase III clinical trial using a tumour growth inhibition (TGI) model. Tumour size measurements from 441 (out of 456) patients were used to build two datasets for which observations were the sum of longest diameters of all measurable lesions (ALL dataset) or following the RECIST 1.

Randomized Phase III Study of FOLFOX Alone or With Pegilodecakin as Second-Line Therapy in Patients With Metastatic Pancreatic Cancer That Progressed After Gemcitabine (SEQUOIA).

Purpose: SEQUOIA compared efficacy and safety of adding pegilodecakin (PEG), a pegylated recombinant human interleukin (IL)-10, with folinic acid, fluorouracil, and oxaliplatin (FOLFOX) in patients following progression on first-line gemcitabine-containing therapy with metastatic pancreatic ductal adenocarcinoma (PDAC).

Patients And Methods: SEQUOIA, a randomized, global phase III study, compared FOLFOX with PEG + FOLFOX as second line in gemcitabine-refractory PDAC. Patients were randomly assigned 1:1 (PEG + FOLFOX:FOLFOX) and stratified by prior gemcitabine and region.

Randomized Phase 2 Studies of Checkpoint Inhibitors Alone or in Combination With Pegilodecakin in Patients With Metastatic NSCLC (CYPRESS 1 and CYPRESS 2).
