Exhibit 99.1

Gyre Therapeutics Presents Poster at the American Association for the Study of Liver Diseases (AASLD) Annual Liver Meeting

SAN DIEGO, Calif., Nov. 13, 2023 – Gyre Therapeutics (“Gyre”) (NASDAQ: GYRE), a clinical-stage biotechnology company developing anti-fibrotic therapeutics for a variety of chronic liver diseases, today announced the presentation of a poster at the American Association for the Study of Liver Diseases’ (AASLD) Annual Liver Meeting, November 10-14, 2023, in Boston, Massachusetts.

Gyre’s lead asset, Hydronidone, is currently being investigated for the treatment of Metabolic Dysfunction Associated Steatohepatitis (MASH)-associated liver fibrosis in the United States. Gyre’s poster presented the potential antifibrotic effects of Hydronidone and its expected mode of action in mouse hepatic fibrosis models.

“We are encouraged by these preclinical results that support Hydronidone’s candidacy as a potential treatment for liver fibrosis,” said Charles Wu, Ph.D., Chief Executive Officer of Gyre Therapeutics. “Our team and collaborators showed Hydronidone’s ability to ameliorate liver fibrosis by inhibiting the activation of hepatic stellate cells (HSCs) via Smad7-mediated Tumor Growth Transforming (TGF)-β degradation. Activation of the HSCs is recognized as a central event in the process of liver fibrogenesis with the TGF as one of the key mediators. The obtained mechanistic data support the potential of Hydronidone for the treatment of liver fibrosis associated with a spectrum of chronic liver diseases. We look forward to initiating the clinical program of Hydronidone in the United States in 2024.”

Key highlights from the poster presentation are below:

• Hydronidone significantly improved liver damage in carbon tetrachloride (CCL4) and 3,5-diethoxycarbonyl-1,4-dihydropyridine (DDC) mouse hepatic fibrosis models and reduced the accumulation of collagen

• Hydronidone inhibited the activation of hepatic stellate cells via Smad7-mediated TGF-β degradation and decreased the expression of fibrosis genes in hepatic stellate cells

• In a ubiquitin-proteasome dependent pathway, Hydronidone promoted the Caveolin-1 mediated TGFβRI degradation via Smad7

• Specific knockdown of Smad7 in vivo blocked the antifibrosis effect of Hydronidone
