Summary for Patent: 9,926,561
Title: | Composition for regenerating normal tissue from fibrotic tissue |
Abstract: | The present invention relates to a pharmaceutical composition and a method for regenerating normal tissue from fibrotic tissue, the pharmaceutical composition and the method employing a collagen-reducing substance. In accordance with the present invention, normal tissue can be therapeutically regenerated from fibrotic tissue. |
Inventor(s): | Niitsu; Yoshiro (Sapporo, JP), Yoneda; Akihiro (Sapporo, JP), Ishiwatari; Hirotoshi (Sapporo, JP) |
Assignee: | Nitto Denko Corporation (Osaka, JP) |
Application Number: | 15/208,440 |
Patent Claims: | 1. A method of treating fibrosis, comprising: (a) identifying a human subject having a fibrotic condition for which a fibrotic tissue continually receives a fibrotic
stimulus; (b) administering multiple doses of a pharmaceutical composition comprising a collagen-reducing substance to the subject in accordance with a dosing schedule, thereby differentiating stem cells into normal tissue cells in the fibrotic tissue
and regenerating normal tissue from the fibrotic tissue in the subject while the fibrotic tissue is receiving the fibrotic stimulus; and (c) terminating said dosing schedule for a period of time effective to regenerate additional normal tissue from the
fibrotic tissue.
2. The method according to claim 1, wherein the collagen-reducing substance is selected from the group consisting of a suppressor of collagen production by collagen-producing cells, a promoter of collagen decomposition, and a suppressor of a collagen decomposition inhibitor. 3. The method according to claim 1, wherein the pharmaceutical composition further comprises a retinoid. 4. The method according to claim 1, wherein the pharmaceutical composition further comprises a targeting agent for collagen-producing cells in fibrotic tissue. 5. The method according to claim 2, wherein the suppressor of collagen production by collagen-producing cells is selected from the group consisting of a TGF.beta. inhibitor, HGF or a substance promoting the production thereof, a PPAR.gamma. ligand, an angiotensin inhibitor, a PDGF inhibitor, relaxin or a substance promoting the production thereof, a substance that inhibits the production and/or secretion of an extracellular matrix component, a cell activity suppressor, a cell growth suppressor, and an apoptosis-inducing substance. 6. The method according to claim 5, wherein the substance that inhibits the production and/or secretion of an extracellular matrix component is an inhibitor of HSP47. 7. The method according to claim 2, wherein the promoter of collagen decomposition is collagenase or a collagenase production promoter. 8. The method according to claim 2, wherein the suppressor of a collagen decomposition inhibitor is a TIMP inhibitor. |
