ClinConnect Summary

This clinical trial is studying a new treatment for women with advanced breast cancer that cannot be removed by surgery or has spread to other parts of the body. The study is looking at a combination of two drugs: HRS-8080 and Dalpiciclib Isethionate Tablets. Participants will first explore the best dosage of these medications and then see how effective they are in treating their condition.

To be eligible for this trial, women aged 18 to 75 who have been diagnosed with advanced breast cancer that has progressed despite previous treatment may qualify. They should have at least one measurable tumor that can be tracked. Participants can expect to receive these medications while being closely monitored by the study team. It's important for anyone considering this trial to know that they will need to agree to use effective birth control during and for a period after the study, and they must be in good enough health to participate. This trial is currently looking for volunteers, so if you or someone you know fits the criteria, it could be an opportunity to help advance breast cancer treatment.
