For the transformation of starting material into the product is needed API synthesis, which involves multiple reaction steps, including reagents, intermediates, catalysts, solvents and others. As a result, low levels of by-products may appear in API as impurities. This impurity may have toxicity, incl. carcinogenicity and genotoxicity, what may cause mutations, potentially leading to cancer. Due to this fact and focusing on ensuring safety of public health is critical to identify, monitor, analyse and control genotoxic impurities and strive to their minimum level. This has led to the crucial need in the development and improvement of analytical methods.
The Genotoxic Impurities in Pharmaceuticals Summit 2021 is focusing on overcoming challenges and barriers, sharing knowledge, strategies, best techniques and new methodologies in GTI predictions, analysis and control during the drug development process, overview and practical implementation of GTI guidelines and regulations (ICH M7 and ICH Q3D), risk assessment, exposure limits calculation and predictions' empowerment through in silico.

12:30 Regulatory Updates on Nitrosamine Impurities.
It has become mandatory to understand current regulations and recommendations by FDA, EMA, WHO and other authorities to implement adequate quality risk management principles to make science-based decisions to mitigate potential risks. Competent staff, sound knowledge and in-depth understanding of products and processes are critical when assessing potential risks to manufacturing processes to ensure that patient safety is adequately protected.

17:00 Analytical Solutions for the Detection and Quantification of Nitrosamines Using Separations and Mass Spectrometry.
The analytical methodology applied for genotoxic impurity analysis needs to provide an appropriate level of sensitivity to meet the required detection limits and demonstrate good accuracy, precision, and reproducibility. In this work, we present robust analytical approaches for the detection and quantification of nitrosamine impurities using UV, MS and HRMS techniques. The performance and sensitivity of these methodologies are demonstrated by analyzing several nitrosamine impurities in drug substances and drug product formulations.

12:30 Continuing development of applied chemical knowledge for an in silico purge tool - Incorporating lessons from nitrosamines.
The impact of nitrosamines within drug substances has been felt widely across the regulatory landscape in the last few years. The application of chemistry knowledge within the risk assessment process for nitrosamines has been one of the subjects that has drawn interest from both industry and regulators. The in silico purge tool, Mirabilis, has therefore been adapting to reflect the lessons which have been learnt from the nitrosamine crisis, incorporating an understanding of both the risk of carry-over, and the risk of formation.

15:30 Handling mutagenic extractable and leachable compounds released from devices.
Genotoxic compounds can be released from some medical devices during their clinical use. The ISO 10993-17:2002 standard outlines steps to assess the risk posed by patient exposure to genotoxic compounds released from device materials. It is important to note; however, that the ISO 10993-17 standard is currently undergoing revision and the procedures for conducting a toxicological risk assessment of genotoxic compounds are likely to change following revision of the standard. This talk will outline the proposed changes to the ISO 10993-17 standard regarding methods to assess the risk posed by patient exposure to genotoxic compounds released from medical devices and will describe steps to mitigate the risk using risk management strategies. The talk will also briefly address how Carcinogenic, Mutagenic, and Reproductive (CMR) compounds will be handled in Europe under the new Medical Devices Regulation 2017/745/EU.

16:10 Can the Ames test adequately predict the carcinogenic potential of nitrosamines?
Mutagenicity data is a core component of the safety assessment data required by regulatory agencies for acceptance of new drug compounds, with the OECD-471 bacterial reverse mutation (Ames) assay most widely used as a primary screen to assess drug impurities for potential mutagenic risk. Previous literature reports indicated that the Ames test might not be sensitive enough to detect the mutagenic potential of N-nitrosamines in order to accurately predict a risk of carcinogenicity. To explore this hypothesis, public Ames and rodent carcinogenicity data pertaining to the N-nitrosamine class of compounds was collated for analysis. Here we present how variations to the OECD 471-compliant Ames test, including type of metabolic activation, solvent type and preincubation/plate incorporation methods, may impact the predictive performance for carcinogenicity. An understanding of optimal conditions for testing of N-nitrosamines may improve both the accuracy and confidence in the ability of the Ames test to identify potential carcinogens.
