Inclusion criteria

Inclusion criteria: 1. Age >=40 years; 2. The study participant has signed the informed consent form, understands the purpose, procedures and content of the study, and voluntarily agrees to participate in the study; 3. IPF diagnosed according to the ATS/ERS/JRS/ALAT clinical practice guideline for idiopathic pulmonary fibrosis (2022) (HRCT showing UIP pattern/probable UIP pattern (confirmed by independent imaging review panel) with or without pathological UIP pattern/probable UIP pattern; for HRCT showing indeterminate UIP pattern, pathology must show UIP pattern/probable UIP pattern) (pathology refers to cryobiopsy or surgical/thoracoscopic lung biopsy); 4. Study participants receiving background pirfenidone or nintedanib may be enrolled if they have been on a stable anti-fibrotic regimen for more than 12 weeks prior to Visit 1 5. IPF patients with >=2 pulmonary function test results within the past 2 years; 6. Adequate organ function, with laboratory test results for blood routine, liver function, renal function and coagulation meeting the following criteria within 7 days before starting treatment: (1) Blood routine: white blood cell (WBC) >=3.5×10^9/L, platelet (PLT) >=80×10^9/L, absolute neutrophil count (ANC) >=1.5×10^9/L, hemoglobin (HGB) >=90 g/L; (2) Liver function: aspartate aminotransferase (AST) <2.5×ULN (<5×ULN in patients with liver metastases), alanine aminotransferase (ALT) <2.5×ULN (<5×ULN in patients with liver metastases), total bilirubin (TIBC) <1.5×ULN; (3) Renal function: serum creatinine (Cr) <1.0×ULN; (4) Coagulation function: prothrombin time, partial thromboplastin time, plasma fibrinogen, and thrombin time within normal range.

Exclusion criteria

Exclusion criteria: 1. Patients with acute exacerbation of IPF within 4 weeks prior to screening or during the screening period; 2. Presence of interstitial lung disease (ILD) other than IPF, including but not limited to: any other type of idiopathic interstitial pneumonia; lung disease associated with fibrogenic agents, other environmental toxins, or drugs; other types of occupational lung disease; granulomatous lung disease; pulmonary vascular disease; systemic diseases including vasculitis, infectious diseases (e.g., tuberculosis), and connective tissue diseases. If the diagnosis is unclear, serological testing and/or multidisciplinary expert panel review should be performed to confirm IPF or other types of ILD; 3. Active viral, bacterial, or fungal infection that is not controlled with appropriate anti-infective therapy; 4. History of malignancy (except for cancers that have been cured or in remission for >=5 years, radically resected basal cell or squamous cell skin cancer, in situ cervical cancer, and resected colonic polyps); 5. Known positive serology for HIV or syphilis, or active hepatitis B virus or hepatitis C virus infection; 6. Presence of mental illness or other conditions that preclude compliance with study treatment and monitoring requirements 7. Known allergy to any component of the immunomodulatory agent; 8. Organ transplant recipients; 9. Judged by the investigator to be unable to complete study follow-up; 10. Pregnant or breastfeeding women.
