Summary
To ensure product safety and efficacy, modifications require scientific validation. This includes demonstrating reduced allergenicity, confirmed potency through clinical and animal studies, and assessing biochemical and biological stability.
Area of Science:
- Immunology
- Biotechnology
- Regulatory Science
Background:
- Allergenicity and antigenicity (potency) are distinct properties.
- Regulatory requirements necessitate rigorous scientific justification for product modifications.
Purpose of the Study:
- To outline the scientific criteria for justifying modifications in products where allergenicity and antigenicity are no longer equivalent.
- To emphasize the need for comprehensive validation of product safety and efficacy.
Main Methods:
- Standardized methods for demonstrating loss of allergenicity.
- Animal and clinical studies to confirm potency.
- Assessment of surrogate markers for clinical efficacy.
- Evaluation of biochemical and biological stability.
Main Results:
- A clear distinction between allergenicity and potency is crucial.
- Standardized methods are available to assess allergenicity reduction.
- Potency requires robust validation through in vivo and in vitro studies.
- Biochemical and biological stability are key indicators of product integrity.
Conclusions:
- Product modifications demand a multi-faceted scientific approach.
- Demonstrating reduced allergenicity and confirmed potency is essential for regulatory approval.
- Comprehensive stability assessments are integral to ensuring product safety and efficacy.

Overview
01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
