Solution Overview

Problem

Current treatments for obesity do not address muscle loss and atrophy, and existing methods for inhibiting myostatin function are economically inefficient and pose health risks, while GLP-1 receptor agonists do not treat muscle loss related to obesity.

Innovation Solution

A combination therapy using a microorganism transformed with a cell surface display vector expressing myostatin and activin A as a bispecific antigen, combined with an approved GLP-1 receptor agonist, to treat muscle loss due to obesity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If myostatin inhibition methods are used to treat muscle loss, then muscle mass increases, but economic efficiency decreases and health risks increase

Engineering Contradiction:
Improvemuscle massVSAvoidsafety and economic efficiency
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent uses a bispecific antibody as an intermediary that simultaneously binds to both myostatin and activin A, blocking their harmful effects without directly introducing foreign proteins or genes. This mediator approach achieves muscle growth while avoiding the safety issues of direct myostatin inhibition and the economic inefficiency of complex biologic production

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention employs a bispecific antibody composition that combines specificity for both myostatin and activin A into a single therapeutic agent. This composite biological material provides dual functionality, addressing multiple aspects of muscle regulation simultaneously while improving economic efficiency through a single-product formulation

Inventive Principle:
Principle #40Composite materials

2Weight of moving object

If GLP-1 receptor agonist alone is used for obesity treatment, then weight loss is achieved, but muscle loss is not addressed

Engineering Contradiction:
Improvebody weightVSAvoidmuscle mass
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent combines GLP-1 receptor agonist therapy with bisspecific antibody treatment in a single composition or concurrent administration regimen. This merging of therapies allows simultaneous achievement of weight loss through GLP-1 mechanism and muscle mass preservation through myostatin/activin A blockade, solving the problem of muscle loss during obesity treatment

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bisspecific antibody provides multi-functional benefits by simultaneously targeting both myostatin and activin A pathways, while being compatible with GLP-1 agonist therapy. This universal approach addresses multiple physiological systems (weight regulation and muscle maintenance) with a single additional agent

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