3rd Annual Genotoxic Impurities Summit: Nitrosamines & Beyond 2023 - uventia

3rd Annual Genotoxic Impurities Summit: Nitrosamines & Beyond 2023

3rd Annual Genotoxic Impurities Nitrosamines & Beyond
Event Details

Conference Overview

The safety, quality and clinical results of drug substances and drug products may be disrupted by the formation of nitrosamines along with other mutagenic impurities. The comprehensive development and production of innovative medicines now inevitably involves estimating impurity profiles as well as managing and monitoring them. To meet the demands of ever-increasing regulatory standards and avoid expensive recalls, proactive detection of genotoxic contaminants should be adopted at every stage of pharmaceutical development.

We plan an online meeting with subject-matter experts to evaluate multiple perspectives on how to handle the concerns of mutagenic impurities. We will cover regulatory-compliant drug impurity profiling practices; helpful hints for adhering to recent ICH M7 and Q3D updates; nitrosamine impurity identification and quantification; risk evaluation of genotoxic impurities; analytical challenges and genotoxicity prediction; establishment of acceptance criteria; and the most recent developments in the analysis of elemental impurities.

Save a seat at our webinar to find out about most effective methods for genotoxic and other mutagenic impurity management.

Summit Agenda

◆  Examining how the CPCA has changed the regulatory landscape for nitrosamines.

◆  Impact on drug manufacturers.

◆  Areas that require further understanding and evolution.

Lhasa Limited, UK

The presentation will start with a short overview of the EDQM and how it fits in the European regulatory system. 

The historical evolution from the outbreak of nitrosamines in June 2018 to today and the actions taken on the EU/EC/EMA regulatory level as well as at EDQM will be provided. 

Finally, the EDQM response to nitrosamines will be provided by detailing the actions undertaken and still ongoing within the three main tracks that are: the texts of the European Pharmacopoeia, the testing of batchs within the Official Medicines Control Laboratories and the Certification (CEP) procedure.

EDQM, Council of Europe, FR

◆  How N-nitrosamines might form within DS and DP and how to assess.

◆  Experiences of Step 2 testing.

◆  Steps taken when an N-nitrosamine and/or N-nitroso drug substance related impurity (NDSRI) is confirmed.

◆  How GSK are assessing risk in R&D.

◆  Reflections and looking forward.

GSK, UK

◆  Misalignments between ICH M7 and regulatory requirements for nitrosamines.

◆  Difficulty in setting acceptable intake (AI) levels for nitrosamine drug substance related impurities (NDSRIs).

◆  Proposals for AIs of nitrosamines of classes of drugs - position papers for nitrosamines of calcium channel blockers, beta-blockers and beta-agonist, and ACE inhibitors.

◆  Use of in vivo mutagenicity data to categorize the potency of NDSRIs.

Teva Pharmaceutical Industries Ltd., IL

◆  In vivo mutation and cancer potency.

◆  Using in vivo mutation data to support potency categorisation.

◆  Next steps and upcoming data sets and approaches.

Swansea University, UK

◆  Understanding of the evolution of the issue – Valsartan to NDSRIs. 

◆  Current risks – progress against deadlines. 

◆  Areas of uncertainty and their impact.

◆  Where will we be in 12 months times.

◆  Assessment of data poor substances: (Q)SARs and read-across.

Safetree Consulting e.U., AT

◆  Different methodologies applied for a comprehensive mutagenicity assessment.

◆  Case studies presenting the overall assessment of impurities associated with QSAR: equivocal predictions, inconsistent in silico predictions, unclassified, misclassified and out of domain chemical moieties.

◆  Analyzing the in vitro Ames test results, in order to provide mutagenicity assessment based on experimental data.

Teva Pharmaceutical Industries Ltd., IL

◆  Ambiguity of guidelines for drugs vs medical devices for calculation of Analytical Evaluation Threshold (AET) for toxicological risk assessment.

◆  Effect of solvent selection and concentration of extracts on impurities profiling.

◆  Chromatographic and spectroscopic skills in mass spectra interpretation for identification of Nitrosamines in screening modes.

Preclintox Services, LLC, USA

◆  The analysis of nitrosamines in drug products is well studied, but little is reported regarding the content of nitrosamines in pharmaceutical rubber.

◆  Highly inconsistent results were obtained using traditional extraction techniques to evaluate the content of nitrosodimethylamine (NDMA) in rubber.

◆  Evidence suggests that NDMA is formed in situ during (and after) extraction.

◆  NDMA may not be present in the rubber in its native form, but may be generated by attempts to detect it.
