Solution Overview

Problem

Current treatments for psoriasis, both systemic and topical, face limitations in efficacy, safety, and the prevention of relapses, with existing medications often causing toxicity and requiring long-term use at high costs, while also being ineffective in managing severe manifestations like psoriatic arthritis and nail psoriasis.

Innovation Solution

The use of pidotimod, or its physiologically acceptable salts, administered systemically or topically, in various formulations to treat psoriasis, potentially combined with other active agents like immunosuppressive agents, Vitamin D analogues, and biologics, to attenuate skin and joint lesions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional systemic treatments (methotrexate, cyclosporine, corticosteroids) are used to treat psoriasis, then immune response is suppressed and skin lesions improve, but toxic effects increase and long-term use is required

Engineering Contradiction:
Improveefficacy in treating psoriasisVSAvoidtoxic effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the immunomodulatory approach from broad immunosuppression to targeted immune response modulation. Pidotimod modifies the immune system's response parameters by enhancing endogenous protective mechanisms while suppressing pathological inflammation, achieving therapeutic effect with reduced toxicity compared to traditional immunosuppressants

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Pidotimod acts as an immunomodulating intermediary substance that regulates the immune system's response to psoriasis. It mediates between the immune system's protective functions and pathological inflammatory responses, achieving balance without the severe side effects of direct immunosuppression

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If biologic agents (monoclonal antibodies, etanercept, adalimumab) are used to treat severe psoriasis, then efficacy is improved, but treatment cost increases significantly and severe adverse events may occur

Engineering Contradiction:
Improveefficacy in treating severe psoriasisVSAvoidsevere adverse events and high cost
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent employs pidotimod, a small molecule immunomodulator with favorable pharmacokinetics and lower cost compared to biologic agents. It provides effective treatment with a more favorable safety profile and reduced economic burden, serving as an alternative to expensive monoclonal antibodies

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent shifts from high-cost biologic therapy to cost-effective immunomodulation with pidotimod. The drug achieves therapeutic results by modulating immune parameters rather than requiring expensive protein-based biologics, reducing both direct treatment cost and indirect economic burden

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If topical treatments are used for localized psoriasis, then safety is improved and side effects are reduced, but treatment is limited to small body surface areas and cannot treat extra-skin manifestations

Engineering Contradiction:
Improveside effectsVSAvoidability to treat extra-skin manifestations
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

Pidotimod exhibits multi-functionality by effectively treating both cutaneous psoriasis and extra-skin manifestations such as psoriatic arthritis and nail psoriasis. A single systemic immunomodulatory agent addresses multiple disease manifestations, overcoming the limitations of topical treatments

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

4Duration of action of stationary object

If long-term treatment is required to maintain psoriasis remission, then relapse prevention is improved, but cumulative toxicity increases and patient compliance decreases

Engineering Contradiction:
Improveduration of remissionVSAvoidcumulative toxicity
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent enables periodic or intermittent treatment regimens with pidotimod, allowing patients to achieve and maintain remission with treatment cycles rather than continuous therapy. This reduces cumulative exposure and toxicity while maintaining effectiveness in preventing relapses

Inventive Principle:
Principle #19Periodic action
