Test dose-dense chemo before surgery for high-growth hormone-positive breast cancer
This Phase 2 study tests a faster, more frequent chemotherapy schedule given before surgery (neoadjuvant therapy) for certain breast cancers that grow quickly. It may help shrink the tumor before the operation and improve treatment response in people who fit the tumor and health criteria.
Shantou, GuangdongAges 18–70 - NCT05733715RecruitingEarly Phase 1
Testing pembrolizumab plus lenvatinib before kidney cancer surgery
This trial tests whether giving pembrolizumab (an immune medicine) and lenvatinib (a targeted medicine) before surgery can shrink or better treat renal cell carcinoma. The goal is to improve surgical outcomes and help the body fight the cancer.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05731726RecruitingPhase 2
New treatment before surgery for locally advanced rectal cancer
This trial tests whether giving serplulimab (an immune medicine) plus CAPEOX chemotherapy and celecoxib before surgery can shrink locally advanced rectal cancer and improve outcomes. It may help by increasing immune attack on the tumor while chemotherapy helps reduce the cancer before the operation.
Hangzhou, ZhejiangAges 18–75 - NCT05733689RecruitingPhase 1
Testing new pre-surgery treatment for stomach and esophagus cancer
This Phase 1 trial tests how well a tailored (response-adapted) chemotherapy plan works before surgery for stomach or gastroesophageal junction cancer. It aims to improve treatment planning while checking early safety.
Orange, CaliforniaAges 18 years+ - NCT05301283RecruitingPhase 2
Adaptive radiation therapy before surgery for soft-tissue sarcoma
This trial tests a personalized (“adaptive”) radiation plan before surgery for high-grade soft-tissue sarcoma that can be removed. It may help shrink the tumor and improve how well surgery can treat the cancer.
Tampa, FloridaAges 18 years+ - NCT05704829RecruitingPhase 2
Trastuzumab-deruxtecan before surgery for HER2-positive early breast cancer
This trial compares giving trastuzumab-deruxtecan before surgery versus standard chemotherapy plus trastuzumab and pertuzumab. It aims to see which approach works better to shrink or control HER2-positive early breast cancer and improve outcomes.
Baden-Baden, Baden-WurttembergAges 18 years+ - NCT05640791RecruitingPhase 2
Durvalumab with chemo before surgery for bile duct cancer
This trial tests giving durvalumab (an immunotherapy drug) together with chemotherapy before surgery for bile duct or gallbladder cancer. The goal is to see if this combination shrinks tumors and improves outcomes for patients whose cancer is considered high-risk but still removable.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT05593497RecruitingPhase 2
Combination therapy before prostate surgery for high-risk prostate cancer
This study tests a combination of hormone therapy and a targeted drug before prostate surgery for men with high-risk prostate cancer that has not spread. The goal is to see if this approach can improve outcomes.
West Los Angeles, CaliforniaAges 18 years+ - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
