The 17 Workshop on Recent Issues in Bioanalysis (17 WRIB) took place in Orlando, FL, USA on June 19-23, 2023. Over 1000 professionals representing pharma/biotech companies, CROs, and multiple regulatory agencies convened to actively discuss the most current topics of interest in bioanalysis. The 17 WRIB included 3 Main Workshops and 7 Specialized Workshops that together spanned 1 week to allow an exhaustive and thorough coverage of all major issues in bioanalysis of biomarkers, immunogenicity, gene therapy, cell therapy and vaccines.

2020 White Paper on Recent Issues in Bioanalysis: Vaccine Assay Validation, qPCR Assay Validation, QC for CAR-T Flow Cytometry, NAb Assay Harmonization and ELISpot Validation ( - Recommendations on Immunogenicity Assay Strategies, NAb Assays, Biosimilars and FDA/EMA Immunogenicity Guidance/Guideline, Gene & Cell Therapy and Vaccine Assays).

The 14 edition of the Workshop on Recent Issues in Bioanalysis (14 WRIB) was held virtually on June 15-29, 2020 with an attendance of over 1000 representatives from pharmaceutical/biopharmaceutical companies, biotechnology companies, contract research organizations, and regulatory agencies worldwide. The 14 WRIB included three Main Workshops, seven Specialized Workshops that together spanned 11 days in order to allow exhaustive and thorough coverage of all major issues in bioanalysis, biomarkers, immunogenicity, gene therapy and vaccine. Moreover, a comprehensive vaccine assays track; an enhanced cytometry track and updated Industry/Regulators consensus on BMV of biotherapeutics by LCMS were special features in 2020.

Infusing global and intercultural perspectives to transform school psychology and school psychologists.

School psychology has been criticized for limited attention to and limited evidence-based resources for diverse populations in domestic and international settings, in part because of its foundations on psychological knowledge generated primarily in North America and Western Europe. Moreover, in the past 25 years, the profession has made insufficient progress in changing its focus toward an ecological systems perspective as initially envisioned by Conoley and Gutkin in 1995 and revisited in this issue. In this article, we embrace and expand that vision to include the infusion of global and intercultural perspectives into school psychology research, training, practice, policy, and advocacy as a means to address cultural diversity within local contexts across the globe, with a particular focus on school psychology within the United States.

Brentuximab vedotin for paediatric relapsed or refractory Hodgkin's lymphoma and anaplastic large-cell lymphoma: a multicentre, open-label, phase 1/2 study.

Background: Despite remarkable progress in the treatment of newly-diagnosed classical Hodgkin's lymphoma and systemic anaplastic large-cell lymphoma, treatment of relapsed or refractory disease remains challenging. The aims of this study were to assess the safety, tolerability, recommended phase 2 dose, and efficacy of brentuximab vedotin in paediatric patients with relapsed or refractory Hodgkin's lymphoma or systemic anaplastic large-cell lymphoma.

Methods: This open-label, dose-escalation phase 1/2 study was done at 12 centres across eight countries (France, Germany, Italy, Mexico, The Netherlands, Spain, UK, and USA).

Understanding the Supersensitive Anti-Drug Antibody Assay: Unexpected High Anti-Drug Antibody Incidence and Its Clinical Relevance.

Numbers of biotherapeutic products in development have increased over past decade. Despite providing significant benefits to patients with unmet needs, almost all protein-based biotherapeutics could induce unwanted immunogenicity, which result in a loss of efficacy and/or increase the risk of adverse reactions, such as infusion reactions, anaphylaxis, and even life-threatening response to endogenous proteins. Recognizing these possibilities, regulatory agencies request that immunogenicity be assessed as part of the approval process for biotherapeutics.

Ethanol metabolism and osmolarity modify behavioral responses to ethanol in C. elegans.

Background: Ethanol (EtOH) is metabolized by a 2-step process in which alcohol dehydrogenase (ADH) oxidizes EtOH to acetaldehyde, which is further oxidized to acetate by aldehyde dehydrogenase (ALDH). Although variation in EtOH metabolism in humans strongly influences the propensity to chronically abuse alcohol, few data exist on the behavioral effects of altered EtOH metabolism. Here, we used the nematode Caenorhabditis elegans to directly examine how changes in EtOH metabolism alter behavioral responses to alcohol during an acute exposure.

Immunomodulatory oligonucleotides containing a cytosine-phosphate-2'-deoxy-7-deazaguanosine motif as potent toll-like receptor 9 agonists.

Bacterial DNA and synthetic oligomers containing CpG dinucleotides activate the immune system through Toll-like receptor (TLR) 9. Here, we compare the immunostimulatory activity of three immunomers with different nucleotide sequences containing a synthetic cytosine-phosphate-2'-deoxy-7-deazaguanosine dinucleotide (CpR), called immunomodulatory oligonucleotides (IMOs), in mouse, human, and monkey systems. IMOs induced IL-12 and IFN-gamma secretion more than a control non-CpG IMO in mice.

Immunopharmacological and antitumor effects of second-generation immunomodulatory oligonucleotides containing synthetic CpR motifs.

Bacterial and synthetic DNAs containing CpG dinucleotides in specific sequence contexts (CpG DNA) activate the vertebrate immune system and produce potent Th1 immune responses. Recently, we reported immunomodulatory oligonucleotides (IMOs) containing 3'-3'-attached novel structures (immunomers) and synthetic immunostimulatory CpR (R=2'-deoxy-7-deazguanosine) dinucleotides show potent stimulatory activity with distinct cytokine secretion profiles. In the present study, we evaluated in vivo immunopharmacological and antitumor properties of second-generation immunomodulatory oligonucleotides (IMOs) either alone or in combination with chemotherapeutic agents.

Self-stabilized CpG DNAs optimally activate human B cells and plasmacytoid dendritic cells.

We recently showed that 5'-terminal secondary structures in CpG DNA affect activity significantly more than those at the 3'-end [Biochem. Biophys. Res.
