Nitrosamine Risk Assessment is a **thorough evaluation of drug product manufacturing processes**, aimed at identifying and mitigating risks associated with nitrosamine impurities. It involves analyzing raw materials, excipients, manufacturing equipment and processes. This process adheres to global regulatory guidelines (EMA, FDA), **ensuring that all detected levels of nitrosamines remain within acceptable limits**. It is an essential requirement for Marketing Authorization Holders (MAHs), API manufacturers, drug product manufacturers, and suppliers. ## Why is it important? Nitrosamine impurities are a significant safety concern due to their high carcinogenic potential, classifying them as a "cohort of concern" among mutagenic impurities. ### High carcinogenic potential Nitrosamines pose significant cancer risks and are subject to strict regulatory limits. ### Regulatory compliance Companies must identify, assess, and mitigate risks to comply with EMA, FDA, and ICH guidelines. ### Avoid costly recalls Proper assessment prevents non-compliance penalties, product recalls, or delays. ### Ongoing regulatory review New data continues to emerge, requiring up-to-date assessments. ## How can we help? No matter what your nitrosamine risk assessment (NRA) needs are, we have different services to support you: ### Risk assessment Comprehensive evaluation of manufacturing processes, addressing all risk factors and root causes outlined in EMA and FDA guidelines. Updates to the NRA as new information arises that needs to be reflected in the report. ### Acceptable limits calculation Assistance with determining acceptable limits based on acceptable intake (AI) calculations for nitrosamine impurities identified as potential risks. Covers nitrosamines listed by EMA and FDA, as well as unknown nitrosamines. Includes support for CPCA AI establishment and exploring different options for acceptable intake determination. ### Review of NRA reports Evaluation of NRA reports prepared by other companies or documentation related to nitrosamine impurities in pharmaceutical components to ensure compliance with regulatory agency requirements. ### Expert support Support in implementing actions derived from the outcomes of the Nitrosamine Risk Assessment, ensuring proper controlling steps are taken to address identified risks effectively. ### Priority strategies Analysis of manufacturing processes for various drug products to identify those most susceptible to nitrosamine impurity risks and propose priorization strategies. ### Nitrosamine toxicological assessment report Toxicological evaluation, including a review of genotoxicity/carcinogenicity data and establishment of acceptable intake using the TD50 value of a surrogate with sufficiently robust carcinogenicity data as a point of departure for AI derivation through SAR and read-across methodologies. ## Our process We follow a structured, step-by-step approach to ensure comprehensive nitrosamine risk management. ### 1. Initial consultation Understand the client's specific needs and regulatory concerns. ### 2. Data collection Gather documentation on the drug product's manufacturing process, including manufacturer statements. ### 3. Risk assessment report Prepare an NRA report identifying potential sources of nitrosamine contamination. ### 4. Report delivery Comprehensive report detailing whether there is a risk of nitrosamine presence. ### 5. Follow-up support Ongoing assistance including acceptable limit calculations for confirmatory testing.
