What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 78 participants in total. It began in 2023-08-16 with a primary completion date of 2025-02.

Brief Summary

This is a multicenter, open-label, single-arm phase I study in patients with advanced solid tumors which consists of a dose escalation part (Part A) and a dose extension part (Part B). Part A aims to evaluate the safety and tolerability of BA1202, and determine the MTD. Part B will also evaluate the preliminary efficacy of BA1202.

Eligibility Criteria

Inclusion Criteria: * Patients who voluntarily sign an IRB-approved informed consent form, and are willing to abide by the restrictions of the study. * Part A: Patients with histologically and/or cytologically confirmed advanced and/or metastatic solid tumors who have progressed on Standard-Of-Care (SOC), are intolerant to SOC, or have no SOC. * Part B: Patients with histologically and/or cytologically confirmed colorectal cancer, non-small cell lung cancer, pancreatic cancer, gastric cancer, who have progressed on Standard-Of-Care (SOC), are intolerant to SOC, or have no SOC.（Specific cohort will be determined after data of dose escalation phase is obtained） * Part B: High expression of CEACAM5 (defined as ≥ 20% of tumor cells with IHC 2+ and/or 3+). * Life expectancy of at least 3 months. * At least one evaluable lesion in Part A and at least one measurable lesion in Part B according to RECIST v1.1. * ECOG score of \< 2. * Absolute neutrophil count ≥ 1.5 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, hemoglobin ≥ 90 g/L. * Total bilirubin ≤ 1.5×ULN, ALT and AST ≤ 2.5×ULN (or ≤ 5.0×ULN for patients with liver metastases). * Serum creatinine ≤ 1.5×ULN, or creatinine clearance ≥50 mL/min. * International normalized ratio (INR) prothrombin time (PT) ≤1.5×ULN, activated partial thromboplastin time (APTT) ≤1.5×ULN. * Blood pregnancy test results were negative for female patients with fertility potential. Patients with fertility potential must agree to use a reliable method of contraception with their sexual partners during the study period and at least 6 months after the last administration. Exclusion Criteria: * Other malignancies within 5 years prior to screening (other than cured stage Ib or lower cervical cancer, non-invasive basal cell or squamous cell skin cancer). * Has a persistent or active infection that requires intravenous treatment. * History of severe cardiovascular and cerebrovascular disease. * Patients with autoimmune diseases requiring drug control or at risk of recurrence of autoimmune diseases. * Received any radiotherapy (other than palliative radiotherapy for bone metastases), chemotherapy, targeted therapy, immunotherapy, cell therapy, or other investigational anticancer agents within 4 weeks prior to first dose of BA1202, unless chemotherapy or targeted therapy is less than 4 weeks after first dose but has eluted ≥5 half-lives. * Have received any previous CEA targeting therapy, including but not limited to monoclonal antibodies, bisspecific antibodies, antibody-coupled drugs (ADCs), chimeric antigen receptor T cells (CAR-T), etc. * A history of allergy to BA1202 or any component of Obinutuzumab, or to other monoclonal antibodies. * Women are planning to become pregnant or are pregnant or breastfeeding. * Other conditions considered unsuitable for enrollment by the investigator.
