WitrynaMice were treated for 3 months with weekly subcutaneous injection of 10 or 30 mg/kg. The impurity content of the parent batch was 0.25%-2.5% of total drug substance. The enriched impurity mixtures contained from 3% to 10% of the various impurities. The expected common class effects were observed at the 30 mg/kg/week dose level in … WitrynaImpurities can be classified into the following categories: • Organic impurities (process- and drug-related) • Inorganic impurities • Residual solvents Organic impurities can arise during the manufacturing process and/or storage of the new drug substance.
