Real-world Study of Pyrotinib-containing Regimens of Advanced HER2-positive Breast Cancer
Given that pyrotinib has been proven to exert significant efficacy against HER2-positive advanced breast cancer in multiple Phase III studies, and the novel ADC drug disitamab vedotin has demonstrated potent anti-tumor activity, there remains insufficient real-world data on their sequential administration. This multicenter, prospective real-world study plans to enroll 500 patients with HER2-positive advanced breast cancer receiving first-line or second-line treatment. It aims to evaluate the efficacy and safety of sequential disitamab vedotin treatment after disease progression or intolerance to pyrotinib-based regimens (first-line: pyrotinib plus trastuzumab combined with chemotherapy; second-line: pyrotinib plus capecitabine). The primary endpoint is real-world second progression-free survival (rwPFS2), while secondary endpoints cover real-world progression-free survival (rwPFS), tumor response, overall survival (OS), time to treatment failure, safety profiles and patient-reported outcomes. It is currently expected to further validate the efficacy and safety of pyrotinib in patients with advanced HER2-positive breast cancer in the real-world setting, and to evaluate the efficacy and safety of recindopril trastuzumab following pyrotinib-containing regimens.

Metarrestin (ML-246) in Subjects With Metastatic Solid Tumors
Background: Metastasis is the spread of cancer from one organ to a nonadjacent organ. It causes 90% of cancer deaths. No treatment specifically prevents or reduces metastasis. Researchers hope a new drug can help. It stops cancer cells from growing and spreading further and possibly shrink cancer lesions in distant organs. Objective: To find a safe dose of metarrestin and to see if this dose shrinks tumors. Eligibility: Adults age 18 and older with pancreatic cancer, breast cancer, or a solid tumor that has not been cured by standard therapies. Also, children age 12-17 with a solid tumor (other than a muscle tumor) with no standard therapy options. Design: Participants will be screened with: * blood tests * physical exam * documentation of disease confirmation or tumor biopsy * electrocardiogram to evaluate the heart * review of their medicines and their ability to do their normal activities Participants will take metarrestin by mouth until they cannot tolerate it or stop to benefit from it. They will keep a medicine diary. Participants will visit the Clinical Center. During the first month there are two brief hospital stays required with visits weekly or every other week thereafter. They will repeat some of the screening tests. They will fill out questionnaires. They will have tests of their cognitive function. They will have an electroencephalogram to record brain activity. They will have a computed tomography (CT) scan or magnetic resonance imaging (MRI). A CT is a series of X-rays of the body. An MRI uses magnets and radio waves to take pictures of the body. Adult participants may have tumor biopsies. Participants will have a follow-up visit 30 days after treatment ends. Then they will have follow-up phone calls or emails every 6 months for the rest of their life or until the study ends.

A Study of Disitamab Vedotin With Other Anticancer Drugs in Solid Tumors
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV with tucatinib works for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
