Recruiting studies
- NCT05318469RecruitingPhase 1/Phase 2
Ivermectin with immunotherapy for metastatic triple-negative breast cancer
This trial studies whether ivermectin, given together with immunotherapy (balstilimab or pembrolizumab), can help treat metastatic triple-negative breast cancer. It mainly looks at safety first, and may also explore how well the treatment works for people whose cancer has spread.

Pembrolizumab plus ADG106 for advanced triple-negative breast cancer
This early-phase study tests pembrolizumab (an immune therapy) combined with ADG106 in people with advanced solid tumors, and specifically triple-negative breast cancer. It looks at whether the treatment can shrink tumors and improve outcomes for cancers that are progressing despite prior therapy.
SingaporeAges 21–99 - NCT05746325Recruiting
Tumor-pulse device for spinal cancer fluid spread
This trial tests whether Tumor Treating Fields (a non-surgical device that delivers treatment signals to cancer cells through the scalp/skin) can help people whose breast or lung cancer has spread into the fluid around the spine and brain. It focuses on people who have cancer cells found in spinal fluid and can safely use the device most of the day.
Jacksonville, FloridaAges 18 years+ - NCT05955105RecruitingPhase 1/Phase 2
ILB-2109 plus toripalimab for advanced solid cancers
This Phase 1/2 study tests a combination medicine (ILB-2109) plus an immune therapy (toripalimab) in people with advanced solid tumors when standard treatments haven’t worked or aren’t available. It aims to find out if the treatment can shrink tumors and is safe enough to keep studying.
Jinan, ShandongAges 18–80 - NCT05968157Recruiting

Optimizing sequential ADC therapy for HER2-low breast cancer
This trial is for people with HER2-low breast cancer who have already received two or more antibody-drug conjugates (ADCs) in a row. Researchers want to find the best order to use these targeted therapies to get the most benefit.
Guangzhou, GuangdongAges Any age - NCT06926075RecruitingPhase 1/Phase 2
Early trial of KESONOTIDE™ for solid tumors
This trial tests a new tablet called KESONOTIDE™ for people with solid tumors that have spread. The goal is to see if it can help when other treatments have stopped working or are not an option.
Kogarah, New South WalesAges 18 years+ - NCT07072728RecruitingPhase 2
Psilocybin therapy for anxiety in cancer patients
This trial tests whether psilocybin (a psychedelic drug given with talk therapy) can help people with cancer who have adjustment disorder—a condition where a cancer diagnosis causes severe anxiety or stress. It focuses on reducing anxiety and improving emotional well-being.
Abbotsford, VictoriaAges 18–80 - NCT07268846Recruiting
Prebiotic supplement before colorectal cancer surgery
This trial tests if taking a postbiotic supplement before surgery for colorectal cancer can improve recovery. It may help patients with adenocarcinoma of the large intestine prepare for their operation.
São Paulo, São PauloAges 18 years+ - NCT07290309Recruiting
Remote exercise program for cancer survivors
This study tests a remote guided exercise program for cancer survivors to see if it helps with recovery and well-being. It is designed for people who have finished their main cancer treatments and are not already exercising a lot.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,460 recruiting breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
