ClinConnect Summary
This clinical trial is studying a new treatment called SKB264 for patients with unresectable recurrent or metastatic triple-negative breast cancer (TNBC). This type of breast cancer is challenging to treat because it doesn’t respond to some of the common therapies. The study aims to find out if SKB264 is more effective and safer than standard chemotherapy options for patients whose tumors do not express a specific protein called PD-L1, or for those who have already been treated with other therapies targeting PD-L1.
To participate in this trial, patients should be aged between 18 and 75, have a confirmed diagnosis of TNBC, and have either newly diagnosed metastatic cancer or have experienced a relapse at least six months after completing previous treatment. They should not have received any previous systemic treatment for their current advanced cancer. Participants will receive either SKB264 or standard chemotherapy and will be closely monitored for effectiveness and any potential side effects. This trial is currently open for enrollment, and it’s a chance for patients to potentially access a new treatment option while contributing to important medical research.
