A Breakthrough Therapeutic Target for Fibrotic Disease Management

Introduction

Fibrosis, the excessive formation of connective tissue due to injury or inflammation, plays a critical role in the progression of several chronic diseases, including liver cirrhosis, pulmonary fibrosis, and cardiac fibrosis. Fibrotic diseases arise from the abnormal differentiation of myofibroblasts, cells that are integral to tissue repair but can cause significant damage when overly activated. Despite its impact on global health, effective treatments targeting fibrosis at the cellular level remain limited. Our patented technology provides a novel approach by targeting CAPN9/CAPNS2 activity, offering a therapeutic strategy to prevent or reverse fibrotic processes associated with various pathologies.

The Limitations of Current Fibrosis Therapies

Existing treatments for fibrotic conditions often focus on managing symptoms rather than addressing the underlying causes of fibrosis. Steroids and anti-inflammatory drugs can reduce inflammation but may not effectively halt or reverse the fibrotic process. As a result, patients with chronic fibrotic diseases often experience ongoing tissue damage, organ failure, and reduced quality of life. The lack of therapies that can directly target the abnormal differentiation of myofibroblasts—one of the key drivers of fibrosis—leaves a critical gap in the medical landscape for those suffering from these conditions.

Targeting CAPN9/CAPNS2: A Novel Therapeutic Strategy

Our patent offers a breakthrough therapeutic approach by targeting CAPN9/CAPNS2, enzymes that regulate myofibroblast differentiation. By inhibiting these enzymes, our technology interrupts the fibrotic cascade at its source, reducing myofibroblast activation and preventing the excessive tissue scarring that leads to disease progression. This mechanism has the potential to not only slow down fibrosis but also reverse some of the damage caused by abnormal tissue remodeling.

This novel approach can be applied across multiple fibrotic conditions, offering a broad spectrum of therapeutic potential. From lung fibrosis to liver disease and cardiac fibrosis, this technology provides an opportunity to address one of the most significant unmet needs in healthcare—effective treatment for fibrotic diseases.

Key Advantages of Licensing This Technology

  • Directly Targets Fibrosis: By focusing on CAPN9/CAPNS2 activity, this therapeutic strategy addresses the root cause of fibrotic disease rather than merely managing symptoms.
  • Broad Application: The technology holds potential for treating a wide range of fibrotic conditions, including liver, lung, and cardiac fibrosis.
  • Potential for Disease Reversal: Unlike current treatments, which often only slow disease progression, this approach may have the ability to reverse some of the tissue damage caused by fibrosis.
  • Reduced Side Effects: Targeted inhibition of CAPN9/CAPNS2 may offer a more refined approach with fewer side effects compared to traditional anti-fibrotic therapies.

A New Direction for Fibrotic Disease Treatment

Licensing this CAPN9/CAPNS2-targeting technology opens up new possibilities for developing treatments that directly impact the fibrotic disease process. By addressing the root causes of myofibroblast differentiation, this patent offers a path to more effective and potentially life-changing therapies for patients with chronic fibrotic conditions. This innovation has the potential to transform the future of fibrosis management.

Provided herein are, inter alia, compositions and methods for identifying and using agents capable of inhibiting myofibroblast transition as well as methods for treating diseases associated with the same in a subject in need thereof.

We claim:

1. A method of treating a fibrotic disease associated with myofibroblast differentiation in a subject in need thereof comprising:

assaying for the presence of calpain-9 (CAPN9) in a biological sample obtained from the subject;
identifying the subject having an elevated level of CAPN9 relative to a healthy subject; and
administering to the identified subject a therapeutically effective amount of at least one small molecule chemical compound that inhibits CAPN9,
wherein the fibrotic disease is liver fibrosis or lung fibrosis.
2. The method of claim 1, wherein the subject is a human.
3. The method of claim 2, wherein the subject is suffering from liver fibrosis.
4. The method of claim 2, wherein the subject is suffering from lung fibrosis.
5. The method of claim 2, wherein the subject is suffering from lung fibrosis resulting from an infection.
6. A method of treating liver fibrosis in a human subject in need thereof comprising:

assaying for the presence of calpain-9 (CAPN9) in a biological sample obtained from the human subject;
identifying the human subject having an elevated level of CAPN9 relative to a healthy human subject; and
administering to the identified human subject a therapeutically effective amount of at least one small molecule chemical compound that inhibits CAPN9.
7. A method of treating lung fibrosis in a human subject in need thereof comprising:

assaying for the presence of calpain-9 (CAPN9) in a biological sample obtained from the human subject;
identifying the human subject having an elevated level of CAPN9 relative to a healthy human subject; and
administering to the identified human subject a therapeutically effective amount of at least one small molecule chemical compound that inhibits CAPN9.
8. The method of claim 7, wherein the subject is suffering from lung fibrosis resulting from an infection.
