Solution Overview

Problem

Current methods for prophylactic treatment of allergies are limited in their ability to prevent sensitization and clinical symptoms across multiple allergens, particularly for individuals who are unsensitized and have not developed clinical symptoms to specific allergens.

Innovation Solution

A composition comprising a first allergen from the genus Dermatophagoides, administered to humans who are not sensitized to it or its corresponding allergens, which reduces the incidence of sensitization and clinical symptoms for both house dust mite and other allergens like grass pollen, cat, milk, and peanut, demonstrating a prophylactic effect through sublingual immunotherapy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single allergen composition is used for prophylactic treatment, then the treatment is simple and easy to administer, but the ability to prevent sensitization to multiple different allergens is limited

Engineering Contradiction:
Improveability to prevent sensitization to multiple allergensVSAvoidcomplexity of treatment composition
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by using a single allergen composition (house dust mite allergen) that serves multiple functions - preventing sensitization not only to house dust mite but also to other unrelated allergens such as grass pollen, cat dander, milk, and peanut. This multi-functional approach allows one treatment to address multiple allergic sensitizations simultaneously, resolving the contradiction between treatment simplicity and broad protective capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If prophylactic treatment is administered to unsensitized individuals, then sensitization can be prevented, but the treatment must be started very early before any allergic response develops

Engineering Contradiction:
Improveeffectiveness in preventing sensitizationVSAvoidtime window for treatment initiation
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by administering the allergen composition to unsensitized infants before they develop sensitization to multiple allergens. The treatment is initiated during infancy (before 12 months of age) when the immune system is still developing and before allergic sensitization occurs, thereby preventing the development of multiple allergen sensitizations rather than treating them after they have already developed.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple allergens are included in the treatment composition, then coverage is broader, but the formulation becomes more complex and difficult to standardize

Engineering Contradiction:
Improvecoverage of different allergen typesVSAvoidstandardization of formulation
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies the extraction principle by isolating and using only the house dust mite allergen as the active ingredient in the composition. Rather than formulating a complex mixture of multiple allergens, the invention extracts the specific protective effect from house dust mite allergen administration to achieve broad protection against multiple unrelated allergens. This simplifies the formulation while maintaining broad protective coverage.

Inventive Principle:
Principle #2Taking out (Extraction)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The use of a house dust mite allergen composition in sublingual immunotherapy significantly reduces the incidence of sensitization and clinical symptoms not only for house dust mite but also for other allergens, such as grass pollen, cat, milk, and peanut, indicating a broad prophylactic effect against various allergens.

Implementation Method 1

administering the allergen to an unsensitised individual in order to induce establishment of a stable population of allergen-specific T-helper-1-like memory lymphocytes, which are capable of inhibiting activity or amplification of allergen-specific T-helper-2-like memory lymphocytes stimulating production of IgE specific to said allergen

AI summary

A composition comprising at least one first allergen, which is a respiratory allergen belonging to a first biological source material group, for use in prophylactic treatment of allergy to at least one second allergen, which is selected from the group consisting of a respiratory and a venomous allergen belonging to a second biological source material group and a food allergen of a food composition, in a subject, wherein the subject has not developed any clinical symptoms of allergy to the first allergen and to the second allergen, and wherein the first and second biological source material groups are not the same.
