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 180 participants in total. It began in 2026-08-31 with a primary completion date of 2029-03.

Brief Summary

This is a phase I/II clinical study to evaluate the safety and efficacy of SKB565 in participants with advanced solid tumors. The study includes a dose escalation stage, a dose expansion stage, and a indication expansion stage.

Participants with histologically or cytologically confirmed advanced solid tumors who have failed standard therapy, have no standard therapy available, or are intolerant to standard therapy. 4. Researchers evaluated based on Response Evaluation Criteria in Solid Tumors(RECIST) Version 1.1 that there is at least one measurable lesion present. 5. Eastern Cooperative Oncology Group (ECOG) score is 0 or 1. 6. Expected survival period ≥ 12 weeks. 7. Participants have sufficient bone marrow, liver, kidney, and coagulation functions. 8.

Presence of esophagotracheal fistula or esophagoaortic fistula, or tumor invasion or compression of surrounding vital organs and blood vessels accompanied by corresponding clinical symptoms. 10. Within 3 months prior to the first administration, there have been intestinal obstruction, gastrointestinal perforation or fistula, urethral fistula, and abdominal abscess. 11. The toxicity of previous anti-tumor treatments has not been relieved, defined as the toxicity has not recovered to Common Terminology Criteria for Adverse Events (CTCAE) Version 6.0 grade 0 or 1. 12. Serious infection occurred within 28 days prior to the first administration. 13. Active hepatitis B or C, or simultaneous infection with Hepatitis B virus(HBV) and Hepatitis C virus(HCV). 14. Human immunodeficiency virus (HIV) test is positive or there is a history of acquired immunodeficiency syndrome (AIDS); Known active syphilis infection. 15. Known active pulmonary tuberculosis. 16. Known history of allogeneic organ transplantation or hematopoietic stem cell transplantation. 17. History of allergies to any components of SKB565 injection or severe hypersensitivity reactions to other monoclonal antibodies. 18. Received chemotherapy, immunotherapy, biological therapy, or other large-molecule antitumor drugs within 28 days prior to the first administration. Received small-molecule targeted therapy or approved antitumor Chinese patent medicine preparations within 14 days prior to the first administration. 19. Within 6 months prior to the first administration, lung lesions received radiation therapy with a total dose greater than 30 Gray. 20. Have undergone major surgical procedures or suffered serious injuries within 28 days prior to the first administration. 21. Those who have received treatment with other clinical investigational drugs within 28 days prior to the first administration. 22. Individuals who have previously received anti-tumor vaccines or have received any active vaccines within 28 days prior to the first administration. 23. Pregnant or lactating women. 24. Participants with a known history of mental illness or substance abuse are unable to cooperate in completing the study. 25. Suffering from local or systemic diseases caused by non malignant tumors, or diseases or symptoms secondary to tumors, which may affect compliance. 26. Any condition that the researcher deems to interfere with the evaluation of the investigational drug, the safety of participants, or the interpretation of research results, or any other condition that the researcher deems unsuitable for participation in this study.
