On Oct 7 and 8, 2024, the US Food and Drug Administration (FDA) and the Center for Research on Complex Generics (CRCG) co-hosted a workshop titled "Scientific and Regulatory Considerations for Assessment of Immunogenicity Risk for Generic Peptide and Oligonucleotide Drug Products". Stakeholders from the FDA, industry, academia, and contract research organizations convened to discuss strategies for advancing risk assessment methodologies and regulatory frameworks for complex generic products. By assembling experts from various sectors, the workshop explored various available strategies for immunogenicity risk assessment, providing valuable insights to support the development and assessment of generic peptide and oligonucleotide drug products. The discussions fostered a deeper understanding of how these methodologies can inform regulatory decision-making and enhance the development of safer and more effective therapeutics.
This study evaluated the pharmacokinetics (PK), safety, and tolerability of TV-44749 in patients with schizophrenia or schizoaffective disorder. TV-44749 is a novel, long-acting, subcutaneous (SC) olanzapine injection designed to leverage the benefits of long-acting injectable treatment, reduce the risk for post-injection delirium/sedation syndrome (PDSS), and maintain the efficacy of olanzapine. In this open-label phase I study, patients completed an oral olanzapine treatment period followed by administration of TV-44749 single doses (SD cohort; 318 mg, 425 mg, or 531 mg) or multiple doses (MD cohort; three consecutive monthly doses of 283 mg or 566 mg). For the SD cohort, the follow-up period was up to 84 days (i.e., day 85) after TV-44749 administration. Patients in the MD cohort received TV-44749 on days 1, 29, and 57 over an 84-day treatment period and were followed until the end of the study. Evaluations included PK, adverse events (AEs), clinical assessments, and injection-site pain. A total of 71 (SD, 42; MD, 29) patients each received ≥ 1 dose of TV-44749. Both cohorts had overall similar baseline characteristics. Following subcutaneous administration, TV-44749 reached clinically relevant plasma concentrations (≥ 10 ng/mL) within 1–2 days, with a maximum observed plasma drug concentration (Cmax) within 11–14 days, followed by a sustained release profile over the dosing period of 1 month. The mean beta half-life values ranged from 5 to 10 days, and the mean apparent terminal half-life range was 11–17 days. The systemic exposure (Cmax and area under the plasma concentration–time curve (AUC)) of olanzapine and its two major metabolites, 10N‑glucuronide and N-desmethyl olanzapine, increased in an approximate dose-proportional manner over the clinically relevant dose range of 283 mg through 566 mg. The relative bioavailability of TV-44749 SD and MD compared with oral olanzapine after single or multiple doses was 112
The 19th Workshop on Recent Issues in Bioanalysis (19th WRIB) took place in New Orleans, LA, USA on April 7-11, 2025. Over 1200 professionals representing pharma/biotech companies, CROs, and multiple regulatory agencies convened to actively discuss the most current topics of interest in bioanalysis. The 19th 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. Moreover, in-depth workshops on "Implementation Practice for the Newest ELN/LIMS Systems" and on "Vaccine Cell-Based/Functional & Molecular Assays as part of the harmonization of vaccine clinical assays global initiative" were the special features of the 19th edition. As in previous years, WRIB continued to gather a wide diversity of international, industry opinion leaders and Regulatory Agency experts working on both small and large molecules as well as gene, cell therapies and vaccines to facilitate sharing and discussions focused on improving quality, increasing regulatory compliance, and achieving scientific excellence on bioanalytical issues. This 2025 White Paper encompasses recommendations emerging from the extensive discussions held during the workshop and is aimed to provide the bioanalytical community with key information and practical solutions on topics and issues addressed, in an effort to enable advances in scientific excellence, improved quality and better regulatory compliance. Due to its length, the 2025 edition of this comprehensive White Paper has been divided into three parts for editorial reasons. This publication (Part 1) covers in the Part 1A the recommendations on Mass Spectrometry Assays and Regulated Bioanalysis/BMV and in Part 1B the Regulatory Inputs on these topics. Part 2 (Biomarkers/BAV, IVD/CDx, Ligand-Binding Assays and Cell-Based Assays) and Part 3 (Gene Therapy, Cell therapy, Vaccines and Biotherapeutics Immunogenicity) are published in volume 18 of Bioanalysis, issues 1 and 2 (2026), respectively.
The Unified Multiple System Atrophy Rating Scale (UMSARS) is widely used as an outcome measure in MSA trials, but it has limitations for clinical trial use. To address these, we developed the Multiple System Atrophy Combined Outcome Assessment (MuSyCA), a comprehensive multimodal tool for disease-modifying MSA trials. The purpose of this manuscript is to describe the development and validation plan for MuSyCA, with emphasis on its structure, intended use, and assessment of reliability, validity, and sensitivity in tracking disease progression. The development of MuSyCA followed a multistep process. Candidate outcome assessments were identified through systematic literature review and analysis of longitudinal data from large MSA cohorts. Content was refined through multiple Delphi-like consensus rounds involving MSA experts, patient advocacy groups representatives, and industry stakeholders. Cognitive interviews conducted in 20 patients with MSA evaluated the clarity and clinical relevance of patient- and clinician-reported outcomes; feedback was incorporated into a subsequent version of the MuSyCA. Validation is ongoing and includes assessment of construct validity, internal consistency, test–retest reliability, and responsiveness. Longitudinal analyses to determine sensitivity to change over time are ongoing. MuSyCA combines patient- and clinician-reported outcomes, biomarkers (neurofilament light chain, neuroimaging), and performance-based measures to capture subjective and objective aspects of MSA progression, enhancing its utility to detect treatment effects in clinical trials. MuSyCa is not intended to be used in clinical practice. MuSyCA offers a multidimensional approach to MSA assessment, supporting precise, disease-relevant evaluations in trials of putative disease-modifying therapies. Its validation will provide a standardized multimodal outcome measure, advancing MSA therapeutic development.
Nitrosamines (NAs) are a diverse class of mutagenic impurities encompassing both small molecules and structurally complex drug-related NAs, referred to as nitrosamine drug substance-related impurities (NDSRIs). NAs display a broad range of carcinogenic potential, from high carcinogenic potency to being weak or even non-carcinogenic. In vitro Ames tests, conducted with both rat and hamster liver-induced S9, and in vivo transgenic rodent (TGR) mutation assays have been used by pharmaceutical sponsors for hazard identification of NDSRIs. A comparative analysis of Ames tests and TGR results for 33 NDSRIs was performed and revealed an accuracy of 79 % between the overall mutagenic calls in the two assays. For NDSRIs with positive TGR results, mutagenic potency estimates were calculated and compared to NAs with robust carcinogenicity and TGR dose-response data. Results from these NAs demonstrated a strong correlation between carcinogenic potency (TD50) and TGR mutagenic potency (BMDL50) (r2 = 0.95), which supports the use of TGR data for both hazard identification and acceptable intake (AI) determination. By integrating quantitative risk assessment tools with TGR assays, this work contributes to a more robust framework for evaluating NA-associated risks.
