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.

Trastuzumab Deruxtecan and Lovastatin in HER2-low and Ultralow Advanced or Metastatic Breast Cancer

The purpose of this study is to evaluate use of lovastatin, a drug that may lower CAV-1 levels, in order to increase HER2 expression on cells and enhance the uptake and efficacy of trastuzumab deruxtecan (T-DXd) in HER2-low and ultralow advanced metastatic breast cancer. Trastuzumab deruxtecan (T-DXd) is an FDA approved antibody drug conjugate for HER2-low and ultralow breast cancer and lovastatin is a cholesterol lowering agent.

G1T48, an Oral SERD, Alone and in Combination With Palbociclib in ER-Positive, HER2-Negative Advanced Breast Cancer

This is a study to investigate the potential clinical benefit of G1T48 as an oral selective estrogen receptor degrader (SERD) alone and in combination with palbociclib, a cyclin dependent kinase 4/6 (CDK 4/6) inhibitor, in patients with estrogen receptor-positive, HER2-negative metastatic breast cancer. The study is an open-label design, consisting of 3 parts: dose-finding portion including food effect (Part 1), G1T48 monotherapy expansion portion (Part 2), and G1T48 in combination with palbociclib expansion portion (Part 3). All parts include 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. The Treatment Phase begins on the day of first dose with study treatment and completes at the Post-Treatment Visit. Approximately, 184 patients may be enrolled in the study.

First-Line Dual Versus Single HER2-Targeted Therapy With Docetaxel for Advanced HER2-Positive Breast Cancer

This retrospective observational cohort study emulates a target trial to compare the effectiveness and safety of two first-line treatment strategies for women with HER2-positive unresectable locally advanced, recurrent, or metastatic breast cancer in routine clinical practice: pertuzumab plus trastuzumab and docetaxel versus trastuzumab and docetaxel. Data were obtained from electronic health records held by the National Health and Medical Big Data (Eastern) Center and linked with the Jiangsu Provincial Mortality Registry. Eligible patients initiated one of the two treatment strategies between January 1, 2020, and December 31, 2024. Time zero was defined as the date of the first administration of the qualifying first-line regimen. No minimum number of treatment cycles was required. The primary outcome was overall survival. Secondary outcomes included progression-free survival and prespecified adverse events.
