Use of trigonal agonist having activities to all of glucagon, GLP-1, and GIP receptors in treatment of sequelae following respiratory infectious diseases
Provided is use of a trigonal agonist having activities to all of glucagon, GLP-1, and GIP receptors, and/or a conjugate thereof in the prevention or treatment of sequelae following respiratory infectious diseases.
1 . A method for treating sequelae following a respiratory infectious disease, comprising administering a pharmaceutical composition to a patient in need thereof, the pharmaceutical composition comprising a pharmaceutically acceptable excipient and a pharmaceutically effective amount of a peptide including any one amino acid sequence of SEQ ID NOS: 1 to 102.
2 . The method of claim 1 , wherein the peptide is in the form of a long-acting conjugate, and the long-acting conjugate is represented by the following Chemical Formula 1:
X-L-F [Chemical Formula 1]
wherein X is a peptide of any one amino acid sequence of SEQ ID NOS: 1 to 102;
L is a linker including ethylene glycol repeating units,
F is an immunoglobulin Fc region, and
- represents a covalent linkage between X and L, and between L and F.
3 . The method of claim 1 , wherein the respiratory infectious disease is an infectious disease caused by respiratory virus.
4 . The method of claim 3 , wherein the respiratory virus is any one selected from the group consisting of adenovirus, vaccinia virus, herpes simplex virus, parainfluenza virus, rhinovirus, varicella zoster virus, measle virus, respiratory syncytial virus, Dengue virus, human immunodeficiency virus (HIV), influenza virus, coronavirus, severe acute respiratory syndrome associated virus (SARS-associated virus), and Middle East respiratory syndrome coronavirus (MERS-CoV).
5 . The method of claim 3 , wherein the respiratory virus is SARS-CoV-2.
6 . The method of claim 3 , wherein the respiratory virus is a variant respiratory virus.
7 . The method of claim 6 , wherein the variant respiratory virus causes sequelae the same as those caused by the respiratory virus.
8 . The method of claim 6 , wherein the variant respiratory virus is any one selected from the group consisting of SARS-CoV-2 alpha variant (B.1.1.7 lineage), SARS-CoV-2 beta variant (B.1.351 lineage), SARS-CoV-2 gamma variant (P.1 lineage), and SARS-CoV-2 delta variant (B.1.617.2 lineage).
9 . The method of claim 1 , wherein the sequelae following a respiratory infectious disease is any one or more selected from the group consisting of fever, dyspnea, cough, pneumonia, pulmonary fibrosis, pain, myalgia, fatigue, inflammation, and nervous system disorders.
10 . The method of claim 9 , wherein the sequelae following respiratory infectious disease is caused by tissue damage due to excessive cytokine secretion.
11 . The method of claim 1 , wherein the sequelae following respiratory infectious disease is post-COVID-19 pulmonary fibrosis.
12 . The method of claim 1 , wherein the administering of the pharmaceutical composition exhibits one or more of the followings:
(i) a reduction in the lung inflammation score;
(ii) a reduction in the expression or secretion of a pro-inflammatory cytokine cytokines;
(iii) a reduction in the pulmonary fibrotic area; and
(iv) suppressed production of inflammasome complexes.
13 . The method of claim 12 , wherein the pro-inflammatory cytokine is any one or more selected from the group consisting of interleukin, tumor necrosis factor, and interferon.
14 . The method of claim 12 , wherein the pro-inflammatory cytokine is IL-1β, TNF-α, or IFN-γ.
15 . The method of claim 1 , wherein the pharmaceutical composition is administered to an individual having cytokine storm syndrome, sepsis, or organ failure due to respiratory viral infection.
16 . The method of claim 1 , wherein the peptide includes an amino acid sequence selected from the group consisting of SEQ ID NOS: 21, 22, 42, 43, 50, 77, and 96.
