简要总结
This study is designed to evaluate the efficacy and safety of first-line treatment ribociclib in combination with aromatase inhibitor (AI) or fulvestrant OR capecitabine with bevacizumab OR paclitaxel with / without bevacizumab in patients with HR-positive, HER2-negative advanced breast cancer with visceral metastasis.
Half of the patients will receive a combination of ribociclib and AI/fulvestrant while the other half will receive capecitabine + bevacizumab or paclitaxel +/- bevacizumab.
详细描述
This is a prospective, randomized, open-label, two-arm, multicenter, interventional phase III trial in Germany. The study will include adult women with HR-positive, HER2-negative advanced breast cancer with visceral metastases, who received no prior therapy for advanced disease.
158 patients will be enrolled and randomized 1:1 (stratified by the presence of lung and / or liver metastases) to receive Arm A: a combination of ribociclib and AI or fulvestrant; OR Arm B: capecitabine + bevacizumab OR paclitaxel +/- bevacizumab
Treatment will be continued until disease progression, intolerable toxicity or death. Progression-free survival (PFS) will be based on tumor assessments by local radiologists/investigator using RECIST v1.1 criteria. Treatment might be continued beyond RECIST-defined progressive disease (PD) in case of negligible or clinically irrelevant disease progression according to the investigator's discretion until clinically relevant disease progression or symptomatic deterioration.
