Recruiting studies
- NCT05706129RecruitingPhase 1/Phase 2

MelbourneAges 18 years+ - NCT07427186Recruiting
Studying how immunotherapy affects the immune system in early-stage cancer
This trial looks at how your immune system responds to immunotherapy given before surgery for early-stage solid tumors (like lung, head and neck, melanoma, or bladder cancer). The goal is to understand why some people respond better, so doctors can improve treatment for future patients.
ToulouseAges 18 years+ - NCT07765927Recruiting
Exercise program for people with breast or gynecologic cancer
This study is testing whether an exercise program for people with breast or gynecologic cancer is feasible to run. It aims to see if patients can participate and follow the program.
Iowa City, IowaAges 18 years+ - NCT04794075Recruiting

This trial tests a structured nursing and education program to support people with non-metastatic breast cancer who take hormone-blocking treatment. It may help you manage side effects and stay supported during follow-up, using online questionnaires and scheduled sessions.
Bourg-en-BresseAges 18–75 - NCT04073706RecruitingPhase 3
Checking lymph nodes with a tracer during endometrial cancer surgery
This trial tests a “sentinel node” biopsy, using a special dye/tracer, during surgery for early-stage endometrial cancer. It may help doctors find whether cancer has spread to lymph nodes while possibly avoiding more extensive lymph node removal.
Houston, TexasAges 18 years+ - NCT05027776RecruitingPhase 3
HPV vaccine study for healthy girls and young women
This trial studies whether a quadrivalent HPV vaccine is safe and helps the body build protection (immunity) against HPV. It enrolls healthy Chinese females who are not already treated for HPV-related infection.
Mianyang, SichuanAges 9–26 - NCT06430541RecruitingPhase 1
Psilocybin therapy for fear of cancer recurrence
This trial tests if psilocybin-assisted therapy can help reduce the intense worry that cancer might come back. It is for people who have finished their main treatments for early-stage breast cancer or advanced ovarian cancer.
Aurora, ColoradoAges 21 years+ - NCT07579117Recruiting
Video-Assisted Breast Surgery With Nipple Preservation
This trial tests a minimally invasive surgical technique that removes breast tissue while preserving the nipple and immediately reconstructing the breast. It may be suitable if you have early-stage breast cancer or are at high genetic risk and need preventive breast removal.
MilanAges 18 years+ - NCT05213962Enrolling by invitation
Radiation after nipple-sparing mastectomy with implant
This study tests local and regional radiation treatment after nipple-sparing mastectomy done with an implant. It may help reduce cancer returning in the breast/nearby tissues for people whose cancer hasn’t spread to distant sites.
Goyang-si, Gyeonggi-doAges 20 years+ - NCT06793813RecruitingPhase 2
Study of cadonilimab for advanced lung cancer
This trial tests a new drug called cadonilimab for people with advanced non-squamous non-small cell lung cancer that has gotten worse after treatment with immunotherapy and chemotherapy. The goal is to see if it helps control the cancer.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06224387RecruitingPhase 1/Phase 2
Study of a new drug for advanced solid tumors
This trial tests a new drug, CTS2190, for people with advanced solid tumors that have not responded to or cannot tolerate standard treatments. The goal is to see if the drug is safe and effective.
Luoyang, HenanAges 18 years+ - NCT06095583RecruitingPhase 3
Toripalimab for limited-stage small cell lung cancer after chemoradiation
This trial tests whether adding toripalimab (an immunotherapy) or toripalimab plus another immunotherapy (tifcemalimab) after standard chemoradiation can help prevent small cell lung cancer from coming back. It is for people with limited-stage disease who have finished initial treatment without the cancer growing.
Harbin, HeilongjiangAges 18 years+ - NCT06719700RecruitingPhase 2
Chemo-radiation with two drugs for limited-stage small cell lung cancer
This trial tests combining standard chemotherapy with radiation (chemoradiotherapy) plus two additional drugs, toripalimab and surufatinib, for people with limited-stage small cell lung cancer. The goal is to see if this combination improves outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06353997RecruitingPhase 2
New immunotherapy combination before surgery for triple-negative breast cancer
This trial tests a new combination of two immunotherapy drugs (INBRX-106 and pembrolizumab) given before surgery for people with early-stage triple-negative breast cancer. The goal is to see if this treatment can shrink the tumor and improve outcomes.
Los Angeles, CaliforniaAges 18 years+ - NCT06627712RecruitingPhase 3
SBRT with immunotherapy and chemo for early-stage triple-negative breast cancer
This trial tests whether combining targeted radiation (SBRT) with immunotherapy (PD-1 inhibitor) and chemotherapy can improve outcomes for people with early-stage triple-negative breast cancer that has not spread far. It aims to find a more effective treatment option.
Sichuan, ChengduAges 18–65 - NCT04345081Recruiting
Compare two breast surgery skin-sparing methods and recovery
This trial compares two types of mastectomy (with skin and nipple options) and implant reconstruction to see which gives better cosmetic results, comfort, and satisfaction. You may help doctors learn which approach leads to a better quality of life after surgery.
BudapestAges 18–65 - NCT07358806RecruitingPhase 1
Study of OCT-598 for advanced solid tumors
This trial tests a new drug called OCT-598, alone or with chemotherapy, for people with advanced solid tumors that have not responded to other treatments. It aims to see if the combination is safe and effective.
Goyang-siAges 18 years+ - NCT07737951Recruiting
Tai chi for joint pain from breast cancer hormone therapy
This trial tests whether tai chi can help reduce joint pain caused by aromatase inhibitors, which are hormone therapies for breast cancer. If you have joint pain from this treatment, tai chi might be a gentle way to find relief.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03872661RecruitingPhase 2
New lung cancer medicines before surgery for unresectable stage III
This Phase 2 trial tests a combination of IBI308 plus bevacizumab and pemetrexed/carboplatin given before surgery, aiming to shrink or control unresectable stage III non-small cell lung cancer. It may help some people become eligible for surgery and improve outcomes, while also testing safety and effectiveness.
Guangzhou, GuangdongAges 18–75 - NCT03975179Recruiting
Frozen biopsy vs no frozen biopsy during breast-conserving surgery
This study compares two approaches during breast-conserving surgery: doing a quick “frozen section” biopsy during the operation versus deciding later without it. It aims to see which approach better guides treatment decisions about whether the cancer is close to the removed tissue edges (margins).
Goyang-siAges 19–70 - NCT04025164Recruiting
Shorter vs standard breast radiation after lumpectomy
This study compares a shorter course of radiation to a standard longer course after breast-conserving surgery (lumpectomy). It’s meant to see which schedule works just as well while focusing on safety and cancer control.
Guiyang, GuizhouAges 18–70 - NCT06960720Recruiting
Weight lifting program for breast cancer fatigue
This trial tests whether a 3-month resistance exercise program (like lifting weights) can help reduce fatigue in women who have had breast cancer. You may be eligible if you were diagnosed with non-metastatic breast cancer 1-3 years ago and feel tired, even if only a little.
Morgantown, West VirginiaAges 18 years+ - NCT05123482RecruitingPhase 1/Phase 2
Early study of AZD8205 for advanced solid tumors
This Phase 1/2 study tests how safe and effective AZD8205 is for people with advanced or metastatic solid cancers that have come back or spread after standard treatments. It may help by finding the right dose and whether AZD8205 works alone or with another treatment in different cancer types.
Duarte, CaliforniaAges 18 years+ - NCT06875414Recruiting
