Beskrivelse
Inclusion Criteria:
- Male or female subjects aged ≥ 18 years old.
- Subjects with locally advanced, unresectable or metastatic solid tumors who have progressed after ≥1 prior systemic therapy for advanced/metastatic disease, or have no available optimal alternative treatments. Qualified tumor types include but are not limited to endometrial carcinoma, urothelial carcinoma, pancreatic cancer, colorectal carcinoma (CRC), head and neck adenocarcinoma (salivary gland adenocarcinoma, lacrimal gland adenocarcinoma, adenocarcinoma of unknown primary of the neck), cervical cancer, ovarian cancer and adenocarcinoma of unknown primary. Biliary tract malignancy, lung cancer and breast cancer are excluded. For CRC patients: documented RAS status (wild-type or mutant) and wild-type BRAF; prior treatment regimen should contain fluoropyrimidine, oxaliplatin and irinotecan unless contraindicated; anti-VEGF therapy when clinically indicated; anti-PD-L1 therapy for MSI-H/dMMR tumors if clinically indicated.
- ECOG Performance Status 0, 1 or 2.
- Confirmed HER2 positivity defined as IHC 3+, or IHC 2+ with positive FISH amplification (per GC criteria).
- Willing and capable of providing adequate tumor specimens for central pathological re-assessment of HER2 status at institutional pathology department. Patients previously treated with HER2-ADC must provide FFPE tumor samples collected after last HER2-ADC administration. Specimens with insufficient tumor cellularity and fine-needle aspiration samples are not acceptable for HER2 testing.
- At least one measurable lesion at baseline per RECIST 1.1 criteria.
- Adequate bone marrow and organ function confirmed within 14 days prior to enrollment: Hemoglobin ≥ 9 g/dL; Platelet count ≥ 75,000/mm³; Absolute neutrophil count (ANC) ≥ 1000/mm³; Serum albumin ≥ 2.5 g/dL; PT, aPTT and INR ≤ 1.5 × ULN; AST/ALT ≤ 3 × ULN; ≤5 × ULN for subjects with liver metastasis; Total bilirubin ≤1.5 × ULN (no liver metastasis); ≤3 × ULN (baseline Gilbert syndrome or liver metastasis); Creatinine clearance ≥30 mL/min (calculated by Cockcroft-Gault formula)
- LVEF ≥50% evaluated via echocardiogram (ECHO) or MUGA scan within 28 days before enrollment.
Exclusion Criteria:
Subjects with any of the following conditions are ineligible:
- Documented spinal cord compression, leptomeningeal disease or clinically active central nervous system (CNS) metastasis.
- Active primary immunodeficiency, confirmed HIV infection, active HBV or HCV infection.
- History of non-infectious interstitial lung disease (ILD)/non-infectious pneumonia requiring steroid therapy, ongoing active ILD/non-infectious pneumonia, or suspected ILD/non-infectious pneumonia that cannot be ruled out by screening imaging.
- History of myocardial infarction, symptomatic congestive heart failure (CHF, NYHA Class II-IV), unstable angina, or any cardiovascular event (including stroke) within 6 months prior to enrollment.
- Pulmonary exclusion items: (a) Clinically significant underlying pulmonary disorders, including but not limited to pulmonary embolism within 3 months before screening, severe asthma, severe COPD, restrictive lung disease, recurrent pleural effusion; (b) Confirmed autoimmune, connective tissue or inflammatory diseases (rheumatoid arthritis, Sjögren's syndrome, sarcoidosis etc.), or suspected pulmonary involvement at screening; full disease details shall be recorded in eCRF for enrolled subjects; (c) Previous total pneumonectomy.
- Confirmed presence of HER2 gene mutation.

Tidsramme |
|---|---|---|
|
Objective Response Rate, ORR
Tidsramme: From the date of first study treatment until disease progression or death from any cause, whichever occurs first, assessed up to 24months.
|
The Objective Response Rate (ORR) is defined as the percentage of patients whose best response on or before the first occurrence of disease progression is a complete response (CR) or partial response (PR).
Tumor responses were assessed by investigators using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
|
From the date of first study treatment until disease progression or death from any cause, whichever occurs first, assessed up to 24months.

|
Progression-Free Survival, PFS
Tidsramme: Through study completion, an average of 2 years.
|
Progression-Free Survival (PFS) is defined as the time from the start of study treatment to the first occurrence of disease progression, or death, whichever occurs first.
Tumor responses were assessed by investigators using RECIST version 1.1.
|
Through study completion, an average of 2 years.
|
|
Disease Control Rate, DCR
Tidsramme: From the date of first study treatment until disease progression or death from any cause, whichever occurs first, assessed up to 24 months.
|
Disease Control Rate (DCR) is defined as the proportion of patients whose best response is CR, PR or SD maintained more than 8 weeks.
Tumor responses were assessed by investigators using RECIST version 1.1.
|
From the date of first study treatment until disease progression or death from any cause, whichever occurs first, assessed up to 24 months.
|
|
Best Overall Response, BOR
Tidsramme: Through study completion, average follow-up of 2 years.
|
Best overall response (BOR) is defined as the best tumor response achieved at any time during treatment, categorized as Complete Response (CR), Partial Response (PR), Stable Disease (SD), or Progressive Disease (PD) per RECIST 1.1 criteria.
|
Through study completion, average follow-up of 2 years.
|
|
