Nitrosamine Risk Assessment
Navigate nitrosamine regulatory complexities with expert guidance
QbD Group specializes in nitrosamine risk assessments, helping pharmaceutical companies identify risks, write reports, calculate acceptable limits, and address regulatory agency responses.
What is nitrosamine risk assessment?
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.
