Conducting your nitrosamine impurity risk assessment

Before conducting your nitrosamine risk assessment, you will need to address the following:

Do you have access to all of the relevant information to assess your potentially toxic compounds?

  • Can you confidently make a safe decision about this substance and mitigate nitrosamine risks?
  • How much uncertainty are you or the regulatory agency willing to accept?
  • Can you defend the decision you have made to regulatory agencies?

If the answer is no, you may decide not to test your target compound in a certain assessment, and instead embark on a read-across assessment to determine:

  • Can you identify a surrogate compound with sufficient data?
  • Does this chemical also contain structural features associated with the toxic endpoints you’re worried about?
  • Or does it belong to a class of compounds with known toxicity?

Instead of embarking on manual read-across methods, companies and regulators worldwide are conducting efficient nitrosamine read-across analysis with Acrostic. To deliver efficient, reliable results, the Acrostic read-across workflow for calculating nitrosamine AI limits, follows these principles:

Access to curated nitrosamine impurity databases

Acrostic retrieves carcinogenicity and in vitro data for potential analogues from Vitic, the Lhasa Complex Nitrosamines data sharing initiative, and LCDB.

Selects potential compound surrogates

Selects compounds based on matching structural features, as proposed in Lhasa publications defining carcinogenic potency levels for NDSRIs.

Rank your suitable nitrosamine analogues

Ranks analogue suitability according to focused similarity, physico-chemical and pharmacokinetic properties.

Confident decision-making for ICH M7 submissions

Based on user selection Acrostic produces a regulatory-ready report, allowing for expert review to justify decisions made.
