Camrelizumab plus chemo before surgery for triple-negative breast cancer
This Phase 2 trial tests adding camrelizumab (an immune therapy) to standard chemotherapy before surgery for people with triple-negative breast cancer that has not spread. It aims to improve how much the tumor shrinks before and around the time of surgery.
Zhengzhou, HenanAges 18–70 - NCT05485766RecruitingPhase 2
Pembrolizumab with cancer medicines for BRCA-mutated triple negative breast cancer
This Phase 2 trial studies a treatment plan given before surgery (neoadjuvant) and after surgery (adjuvant) for people with BRCA1/2-mutated triple negative breast cancer that has not spread. It aims to improve how well the cancer responds and how long people stay cancer-free.
Gifu, GifuAges 18 years+ - NCT05496036RecruitingPhase 2
Pembrolizumab before surgery for resectable Merkel cell cancer
This trial tests pembrolizumab (an immune therapy) given before surgery to shrink Merkel cell carcinoma and improve outcomes. Participants also have extra tumor biopsies to study biomarkers, which may help explain who benefits most.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05503667RecruitingPhase 2
Testing EGFR drugs before lung surgery in certain stage III cancers
This trial tests whether taking furmonertinib alone, or furmonertinib plus bevacizumab, before surgery can improve outcomes for people with EGFR-mutated lung adenocarcinoma that has not spread to distant organs. It may help shrink the tumor and make surgery more effective.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05523245Recruiting
AI MRI test to predict treatment response in rectal cancer
This study uses an AI computer program to read special MRI images and predict how well treatment (given before surgery) will work for people with locally advanced rectal cancer. It may help doctors better plan who benefits most from neoadjuvant therapy (treatment before surgery).
