Solution Overview

Problem

Elevated levels of galectin-3 (gal-3) in circulation exacerbate various disease conditions, including cancer, inflammation, and fibrosis, complicating treatment and interfering with conventional medical therapies.

Innovation Solution

Plasmapheresis is used to selectively remove or inactivate gal-3 from the plasma, allowing for reduced levels of biologically active gal-3 in circulation, which can be combined with gal-3 binding agents to enhance their effectiveness in targeting gal-3 in tissues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If plasmapheresis is used to remove gal-3 from circulation, then gal-3 levels are reduced, but the procedure is invasive and requires monitoring

Engineering Contradiction:
Improvecirculating gal-3 levelsVSAvoidplasmapheresis procedure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent applies plasmapheresis to extract and remove gal-3 from the blood circulation system. Blood is drawn, plasma is separated, gal-3 is removed through binding agents or filtration, and the remaining plasma is returned to the patient, thereby reducing circulating gal-3 levels.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs binding agents (such as antibodies or lectins) as intermediaries that selectively bind to gal-3 in the plasma, facilitating its removal. These intermediaries act as mediators between the plasma and the removal mechanism, enabling specific targeting of gal-3.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If gal-3 levels are elevated, then cancer progression and inflammation are exacerbated, but reducing gal-3 requires invasive procedures

Engineering Contradiction:
Improvecancer progression and inflammationVSAvoidease of gal-3 reduction
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent removes gal-3 from the circulation through plasmapheresis, extracting this harmful substance from the blood stream to reduce its ability to promote cancer progression and inflammation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Binding agents serve as intermediaries that specifically target and bind to gal-3, enabling its selective removal from circulation and reducing its harmful effects on cancer and inflammation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If conventional therapies are used, then treatment is administered, but gal-3 interferes with therapeutic effectiveness

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidgal-3 interference with therapy
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent performs plasmapheresis to remove gal-3 from circulation before administering conventional therapies. This preliminary action eliminates the interference that gal-3 would otherwise have on therapeutic effectiveness, allowing treatments to work more reliably.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By removing gal-3 through plasmapheresis, the patent eliminates this harmful intermediary that was interfering with the effectiveness of conventional therapies, thereby improving treatment reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention is directed to the removal of serum gal-3 from circulation by plasmapheresis using gal-3 binding agents in either a fixed bed, or in a form easily removed, such as by being complexed with magnetic particles. This method, on its own, brings a sharp reduction and relief from the inflammation and fibroses that can be induced by circulating gal-3. The process may be combined with the administration of gal-3 binding agents, such as modified citrus pectin, to further lower unbound gal-3 levels, to the point where gal-3 in the tissues may be addressed. This method may also be combined with removal of TNF receptors to provide an effective treatment for cancer.
