Overview

This is the first-in-human clinical study of TQB3122, aiming to evaluate the safety, tolerability, and pharmacokinetic characteristics of TQB3122 in advanced solid tumors, and to preliminarily explore its efficacy in solid tumors.

Eligibility

Inclusion Criteria:

• The subject voluntarily participates in this study, signs the informed consent form, and has good compliance;
• Gender is not restricted; age (calculated as of the date of signing the informed consent form): 18-75 years old;
• Eastern Cooperative Oncology Group Performance Status (ECOG PS) score: 0-1; expected survival period ≥ 3 months;
• Patients with histologically or cytologically confirmed advanced malignant solid tumors, including but not limited to epithelial ovarian cancer, fallopian tube cancer, primary peritoneal cancer, breast cancer, prostate cancer, etc.;
• Advanced solid tumors that have failed standard treatment (disease progression or intolerance) or for which there is no standard treatment plan;
• For Phase Ib (dose expansion stage), except for patients receiving maintenance treatment for ovarian cancer/fallopian tube cancer/primary peritoneal cancer, other patients are required to have target lesions meeting the RECIST 1.1 criteria. For Phase Ia (dose escalation stage), measurable lesions are not required;
• Good function of major organs;
• Women of childbearing age must agree to use effective contraceptive measures during the study and within 6 months after the end of the study; serum or urine pregnancy test must be negative within 7 days before enrollment, and they must be non-lactating subjects; men must agree to use effective contraceptive measures during the study and within 6 months after the end of the study.

Exclusion Criteria:

• History of other malignant tumors within 3 years prior to the first administration of the study drug;
• Failure to recover from toxicity and/or complications of previous interventions to CTCAE ≤ Grade 1;
• Risk of bleeding;
• Arterial thrombotic events occurring within 6 months prior to the first administration;

• Active or uncontrolled severe infections;
• Active syphilis; HIV infection or other immunodeficiency diseases; active hepatitis B or active hepatitis C;
• Complicated with moderate to severe pulmonary diseases that significantly affect respiratory function;
• Patients with active autoimmune diseases requiring systemic treatment (e.g., disease-modifying drugs, corticosteroids, or immunosuppressants);
• Receipt of systemic treatment with prednisone \> 10 mg/day or equivalent drugs, or any other form of immunosuppressive therapy within 2 weeks prior to administration;
• History of organ transplantation (except corneal transplantation), allogeneic or autologous hematopoietic stem cell transplantation;
• Poorly controlled diabetes mellitus;
• Patients with leptomeningeal (including arachnoid and pia mater) metastases;
• Known central nervous system (CNS) involvement;
• Presence of massive serous cavity (pleural, peritoneal, or pericardial) effusions requiring repeated drainage to relieve clinical symptoms, or receipt of therapeutic serous cavity effusion drainage within 2 weeks prior to treatment;
• Current intestinal obstruction;
• Known allergy to the components of the study drug;
• Receipt of anti-tumor treatments such as radiotherapy, chemotherapy, targeted therapy, or immunotherapy within 4 weeks prior to the first administration;
• Receipt of Chinese patent medicines explicitly indicated for anti-tumor use in their drug labels approved by National Medical Products Administration (NMPA) within 2 weeks prior to the first administration;
• According to the investigator's judgment, subjects with concomitant diseases that severely endanger their safety or affect the completion of the study, or those deemed unsuitable for enrollment for other reasons.
