Clinical Trial Summary

The study aims to evaluate the efficacy and safety of IAH0968 in combination with gemcitabine and cisplatin for the treatment of HER2-positive unresectable advanced/metastatic malignant tumors and cholangiocarcinoma. The study is divided into two stages: Phase Ib, an open-label, non-randomized, multicenter dose-escalation trial, and Phase II, a randomized, double-blind, parallel-controlled, multicenter trial.


Description:

Phase Ib is an open-label, non-randomized, multicenter dose-escalation trial. It utilizes the classic "3+3" design to investigate the safety and tolerability of IAH0968 in combination with gemcitabine and cisplatin for the treatment of HER2-positive unresectable advanced/metastatic malignant tumors and cholangiocarcinoma. Phase II study is a randomized, double-blind, parallel-controlled, multicenter research design. It aims to investigate the efficacy of IAH0968 in combination with gemcitabine and cisplatin for the treatment of HER2-positive unresectable advanced/metastatic malignant tumors and cholangiocarcinoma.

Eligibility Inclusion Criteria: Phase Ib 1. The age of the participant should be 18 years or older. 2. The participant should have been diagnosed with HER2-positive advanced solid tumors that have failed standard treatment, as confirmed by pathological histology or cytology. Standard treatment failure is defined as disease progression during or after the last treatment, or inability to tolerate treatment due to severe toxicity (grade = 4 hematologic toxicity or grade = 3 non-hematologic toxicity following previous standard treatment). HER2 positivity is defined as proven HER2-positive through immunohistochemistry (IHC) staining and/or fluorescence in situ hybridization (FISH). The interpretation and standards for HER2 positivity in breast cancer will follow current breast cancer guidelines, and for HER2 positivity in cancers other than breast cancer, current gastric cancer guidelines will be followed (Appendix 9). 3. The GC regimen is the frontline standard treatment for the specific type of cancer (including urinary tract carcinoma, NSCLC, pancreatic cancer, nasopharyngeal carcinoma, etc.). 4. The participant should have at least one measurable lesion according to RECIST 1.1 criteria, and the measurable lesion should not have undergone any local treatment (including local radiotherapy, ablation, and intervention therapy). 5. The ECOG performance status should be 0 or 1 (refer to Appendix 3). 6. During the screening phase, the participant's organ functions should be relatively normal (upper limit of normal values based on the respective study center's range), including: - Absolute neutrophil count (ANC) = 1.5 × 109/L - Hemoglobin (Hgb) = 90 g/L - Platelet count (PLT) = 90 × 109/L - Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 2.0 × upper limit of normal (ULN), or = 5.0 × ULN for patients with liver metastasis - Total bilirubin (TBIL) = 1.5 × ULN - Serum creatinine (Cr) = 1.5 × ULN, or creatinine clearance = 50 mL/min calculated according to the Cockcroft-Gault formula (refer to Appendix 2) - All premenopausal women and women within 12 months of menopause should have a negative pregnancy test. - Left ventricular ejection fraction (LVEF) = 50%. - Prothrombin time or international normalized ratio = 1.5 × ULN, unless the patient is receiving anticoagulant therapy. If the patient has received platelet growth factors and/or granulocyte colony-stimulating factors prior to the above examinations, a washout period of at least 1 week is required. 7. The expected survival period should be = 3 months. 8. The patient should agree to use at least one medically acceptable contraceptive method during the study treatment period and within 6 months following the end of the study treatment (for women: intrauterine device, oral contraceptives, or condoms, etc.; for men: condoms, abstinence, etc.), and female patients should not be lactating. The patient should have full understanding of the study content, procedures, and potential risks and benefits, and should sign the informed consent form. The patient should demonstrate good compliance and be able to cooperate with the study and follow-up. Phase IIa 1. The age of the participant should be 18 years or older. 2. The participant should have been diagnosed with locally advanced or metastatic HER2-positive BTC (biliary tract cancer) confirmed by pathological histology or cytology, and should not have received systemic chemotherapy treatment. 3. The participant should have at least one measurable lesion according to RECIST 1.1 criteria, and the measurable lesion should not have undergone any local treatment (including local radiotherapy, ablation, and intervention therapy). 4. The ECOG performance status should be 0 or 1 (refer to Appendix 3). 5. During the screening phase, the participant's organ functions should be relatively normal (upper limit of normal values based on the respective study center's range), including: - Absolute neutrophil count (ANC) = 1.5 × 109/L - Hemoglobin (Hgb) = 90 g/L - Platelet count (PLT) = 90 × 109/L - Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 2.0 × upper limit of normal (ULN), or = 5.0 × ULN for patients with liver metastasis - Total bilirubin (TBIL) = 1.5 × ULN - Serum creatinine (Cr) = 1.5 × ULN, or creatinine clearance = 50 mL/min calculated according to the Cockcroft-Gault formula (refer to Appendix 2) - All premenopausal women and women within 12 months of menopause should have a negative pregnancy test. - Left ventricular ejection fraction (LVEF) = 50%. - Prothrombin time or international normalized ratio = 1.5 × ULN, unless the patient is receiving anticoagulant therapy. 6. The expected survival period should be = 3 months. 7. The patient should agree to use at least one medically acceptable contraceptive method during the study treatment period and within 6 months following the end of the study treatment (for women: intrauterine device, oral contraceptives, condoms, etc.; for men: condoms, abstinence, etc.), and female patients should not be lactating.
