SAN DIEGO, March 26, 2024 (GLOBE NEWSWIRE) -- Gyre Therapeutics, Inc. (“Gyre”) (Nasdaq: GYRE), a clinical-stage biotechnology company developing anti-fibrotic therapeutics for a variety of chronic organ diseases, today announced financial results for the full year ended December 31, 2023 and provided a business update.

“2023 was a transformational year for Gyre as we successfully monetized our legacy assets, returned cash to stockholders, and expanded into the attractive liver fibrosis space with the acquisition of F351, a structural analogue of the approved anti-fibrotic drug ETUARY^® (Pirfenidone). We are extremely encouraged by the data from our Phase 1 clinical trial in healthy volunteers in the United States, which demonstrated a safety profile consistent with that observed in the Phase 2 proof-of-concept trial completed in the PRC. We expect to receive clearance from the U.S. FDA for the initiation of a Phase 2a trial in NASH-associated liver fibrosis by the end of 2024,” said Han Ying, Ph.D., Chief Executive Officer of Gyre. “In addition, we remain on track to report data from Gyre Pharmaceuticals’ Phase 3 trial evaluating F351 for the treatment of CHB-associated liver fibrosis in the PRC by early 2025. Sales of ETUARY remained strong, increasing 13% from 2022 as Gyre Pharmaceuticals maintained its market-leading position in the PRC IPF market, providing funding for our clinical development plans.”

As of December 31, 2023, the carrying value of the CVR derivative liability was $4.7 million on the consolidated balance sheet.

ETUARY (Pirfenidone capsules) Sales Update

ETUARY (Pirfenidone): Pirfenidone, the first anti-fibrotic drug approved for idiopathic pulmonary fibrosis (“IPF”) in Japan, the EU, the United States and the PRC, is a small molecule drug that inhibits the synthesis of tumor growth transforming (“TGF”)-β1, TNF-α, and other fibrosis and inflammation modulators. ETUARY became commercially available in the PRC in 2011 and has been included in the National Reimbursement Drug List since 2017.

• Generated sales of $112.1 million in 2023. For the year ended December 31, 2023, Gyre Pharmaceuticals generated $112.1 million in sales of ETUARY, representing an increase of 13% from the previous year. As of year-end, Gyre’s sales and marketing team included 391 employees with an average of nine years of experience and covered 35,512 hospitals and pharmacies across 30 provinces, autonomous regions and municipalities across the PRC. Gyre expects 2024 sales of ETUARY to grow due to ETUARY’s prominent market position and anticipated sustained increases in the prevalence of IPF.

Clinical Development Updates

F351 (Hydronidone): F351 is a structural derivative of the approved anti-fibrotic drug ETUARY (Pirfenidone) with a TGF-β1 mechanism of action and is currently being evaluated by Gyre for the treatment of nonalcoholic steatohepatitis (“NASH”)-associated liver fibrosis in the U.S. and by Gyre Pharmaceuticals for the treatment of chronic hepatitis B (“CHB”)-associated liver fibrosis in the PRC.

• Expects to report topline data from Phase 3 clinical trial evaluating F351 for the treatment of CHB-associated liver fibrosis in 2025. In October 2023, Gyre Pharmaceuticals completed enrollment of its Phase 3 trial in patients with CHB-associated liver fibrosis in the PRC. The study is evaluating 248 patients with a primary endpoint of the reduction of the liver fibrosis score (Ishak Scoring System) by at least one grade after taking F351 in combination with Entecavir.

F573: Gyre Pharmaceuticals is developing F573, a caspase inhibitor and potential Category 1 new drug, for the treatment of acute/acute-on-chronic liver failure (“ALF/ACLF”).

• Gyre Pharmaceuticals is conducting a randomized, double-blind, placebo-controlled Phase 2 clinical trial in the PRC to assess the safety and efficacy of F573 for injection in the treatment of liver injury/failure.

Preclinical Development Updates

• F528: Gyre Pharmaceuticals is evaluating F528 in preclinical studies as a potential first-line therapy for the treatment of chronic obstructive pulmonary disease (“COPD”). F528 is a novel anti-inflammation agent that targets inhibition of multiple inflammatory cytokines and has the potential to modify the progression of COPD with low toxicity in vivo.

• F230: Gyre Pharmaceuticals is evaluating F230 for the treatment of pulmonary arterial hypertension (“PAH”). F230 is a selective endothelian receptor antagonist.

Financial Results

Cash Position

As of December 31, 2023, Gyre had cash and cash equivalents of $33.5 million, compared to $25.2 million as of December 31, 2022. The $8.3 million change was primarily due to a $25.9 million increase from net cash provided by operating activities, a $19.8 million decrease from net cash used in investing activities and a $2.5 million increase from net cash provided by financing activities.

Financial Results for the Full Year Ended December 31, 2023

• Revenues: For the full year ended December 31, 2023, revenues were $113.5 million as a result of Gyre’s indirect controlling interest in Gyre Pharmaceuticals. For the full year ended December 31, 2022, revenues were $102.3 million. The increase was driven by a $12.6 million increase in sales of pharmaceuticals products, driven by enhanced marketing and sales initiatives in regions of the PRC where sales were previously lower in 2022, partially offset by a $1.4 million decrease in revenue related to a one-time licensing fee recognized in 2022.

• Cost of Revenues: For the full year ended December 31, 2023, cost of revenues was $4.6 million as a result of Gyre’s indirect controlling interest in Gyre Pharmaceuticals. For the full year ended December 31, 2022, cost of revenues was $4.8 million. The decrease was primarily driven by a $0.3 million reduction attributed to favorable foreign exchange rate fluctuations and a $0.2 million decrease in stock-based compensation. These reductions were partially offset by a $0.3 million increase in cost of revenues due to increased sales.

• Selling and Marketing Expense: For the full year ended December 31, 2023, selling and marketing expense was $61.2 million, compared to $54.2 million for the same period in 2022. The increase was primarily driven by a $3.8 million increase in selling and marketing payroll costs due to increased staff, a $3.5 million increase in promotional expenses and a $0.7 million increase in traveling expenses, partially offset by a $1.3 million decrease in stock-based compensation.

• R&D Expense: For the full year ended December 31, 2023, research and development expense was $13.8 million, compared to $16.7 million for the same period in 2022. The decrease was primarily attributable to a decrease in stock-based compensation and pre-clinical research expenses.

• G&A Expense: For the full year ended December 31, 2023, general & administrative expense was $14.7 million, compared to $17.4 million for the same period in 2022. The decrease was primarily attributable to a decrease in stock-based compensation.

Use of Non-GAAP Financial Measures by Gyre Therapeutics, Inc.

Gyre reports financial results in accordance with accounting principles generally accepted in the United States (“GAAP”). This release presents the financial measure “adjusted net income (loss),” which is not calculated in accordance with GAAP. The most directly comparable GAAP measure for this non-GAAP financial measure is “net income (loss).” Adjusted net income (loss) presents Gyre’s results of operations after excluding acquired in-process research and development, loss from change in fair value of warrants, stock-based compensation, divestiture losses, and income tax adjustments. This is meant to supplement, and not substitute, Gyre’s financial information presented in accordance with GAAP. Adjusted net income (loss) as defined by Gyre may not be comparable to similar non-GAAP measures presented by other companies. Management believes that presenting adjusted net income (loss) provides investors with additional useful information in evaluating the Gyre’s performance and valuation. See the reconciliation of adjusted net income (loss) to net income (loss) in the section titled “Reconciliation of GAAP to Non-GAAP Financial Measures” below.

About F351 (Hydronidone)

F351 is a structural analogue of the approved anti-fibrotic (IPF) drug Pirfenidone and has been shown to inhibit in vitro both p38γ kinase activity and TGF-β1-induced excessive collagen synthesis in hepatic stellate cells (“HSCs”), which are recognized as critical event in the development and progression of fibrosis in the liver. This is further supported by its anti-proliferative effects on the HSCs in the liver. In vitro anti-fibrotic effects of F351 were also confirmed in several established in vivo models of liver fibrosis such as CC1₄-induced liver fibrosis mouse model, DMN-induced liver fibrosis rat model, and HSA-induced liver rat model, as well as mouse model of NASH fibrosis (CC1₄+Western High Fat Diet).

About Gyre Pharmaceuticals

Gyre Pharmaceuticals is a commercial-stage biopharmaceutical company committed to the research, development, manufacturing and commercialization of innovative drugs for organ fibrosis. Its flagship product, ETUARY (Pirfenidone capsule), was the first approved treatment for IPF in the PRC in 2011 and has maintained a prominent market share (2023 net sales of $112.1 million). In addition, Gyre Pharmaceuticals is evaluating F351 in a Phase 3 clinical trial in CHB-associated liver fibrosis in the PRC, which is expected to readout topline data by early 2025. F351 received Breakthrough Therapy designation by the National Medical Products Administration’s (“NMPA”) Center for Drug Evaluation in March 2021. Gyre Pharmaceuticals is also developing treatments for COPD, PAH and ALF/ACLF. In October 2023, Gyre Therapeutics acquired an indirect majority interest in Gyre Pharmaceuticals (also known as Beijing Continent Pharmaceuticals Co., Ltd.).

About Gyre Therapeutics
