Cleveland, OhioAges 18 years+ - NCT05681780RecruitingPhase 1
CD40L-treated immune cells for advanced lung cancer with certain gene changes
This Phase 1 study tests a lab-made immune cell treatment (TIL) boosted with CD40L, plus nivolumab, for stage IV or returning non-small cell lung cancer with specific gene changes (EGFR, ALK, ROS1, or HER2). It aims to help your immune system attack the cancer after it has grown despite standard treatments.

Study of a new drug for PIK3CA-mutated HR+ HER2- breast cancer
This early-stage study tests the safety and tolerability of TOS-358 in women with HR-positive, HER2-negative breast cancer that has a specific gene change (PIK3CA). It may help learn whether this targeted treatment is safe enough to move forward.
Chicago, IllinoisAges 18 years+ - NCT05748834RecruitingPhase 2
Tucatinib plus Doxil for HER2-positive metastatic breast cancer
This Phase 2 study tests tucatinib (a HER2-targeted pill) plus Doxil (a chemotherapy medicine) to slow or shrink HER2-positive metastatic breast cancer that has been treated before. It may help by targeting HER2 cancer cells more effectively than past treatments alone.
Columbia, MarylandAges 18 years+ - NCT05751018RecruitingPhase 2
Pyrotinib for first treatment of HER2-mutated lung cancer
This Phase 2 trial studies pyrotinib as a first (initial) anti-cancer treatment for advanced lung cancer that has specific HER2 changes. It aims to shrink tumors and control the cancer, especially in people whose test results show HER2 insertion mutation, point mutation, or amplification.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05760612RecruitingPhase 3
After breast cancer surgery, test neratinib plus trastuzumab
This trial studies whether adding neratinib to standard trastuzumab treatment after neoadjuvant (before-surgery) therapy lowers the risk of breast cancer coming back. It is for people whose breast cancer is hormone-receptor positive and HER2 positive, with residual cancer found after neoadjuvant treatment.
GuangzhouAges 18–70 - NCT05769010RecruitingPhase 2
HER2-positive or low breast cancer brain metastasis drug study
This Phase 2 study tests SHR-A1811 in people with HER2-positive (or HER2-low) advanced breast cancer that has spread to the brain. It aims to shrink brain tumors and control the cancer in the brain, especially when there was no need for urgent local treatment like radiation or surgery.

- Are there clinical trials for her2?
- Yes. Clin2 currently lists 608 recruiting her2 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 her2 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 her2 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.
