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.

Elacestrant + Everolimus in Patients ER+/HER2-, ESR1mut, Advanced Breast Cancer Progressing to ET and CDK4/6i.
This trial will study a type of advanced breast cancer (ABC) defined as endocrine receptor (ER)-positive/human epidermal growth factor receptor 2(HER2)-negative and estrogen receptor 1 (ESR1)-mutated. Patients will be treated with elacestrant, a compound that acts as a selective estrogen receptor degrader, and everolimus (or placebo), a kinase inhibitor indicated for the treatment of postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer. The main purpose of the study is to analyze the efficacy (to find out how effective a treatment is) of elacestrant plus everolimus therapy in patients who have ER-positive/HER2-negative, ESR1-mutated, ABC progressing to endocrine therapy and cyclin-dependent kinase 4/6 (CDK4/6) inhibitor. The efficacy of elacestrant plus everolimus combination will be determined by assessing the period from elacestrant plus everolimus (or placebo) treatment initiation until to the first occurrence of disease progression, unacceptable toxicity, death, or discontinuation from the study treatment for any other reason, whichever occurs first, defined as progression free survival. Rigorous eligibility criteria based on specific co-morbidities and clinicopathologic features of their disease have been designed to minimize the risk of patients participating in this study. The anticipated favorable clinical benefits of elacestrant combined with everolimus are projected to outweigh the risks of this treatment. This study will be performed in full compliance with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) and all applicable local Good Clinical Practice (GCP) and regulations.

This phase II study focuses on women with rapidly progressive hormone receptor-positive and HER2-negative advanced breast cancer, including patients with symptomatic visceral metastases, rapidly increasing tumor burden, impending organ dysfunction, or highly symptomatic non-visceral disease. These patients often require prompt and effective systemic treatment. The purpose of the study is to determine whether first-line ribociclib combined with endocrine therapy can provide effective and rapid tumor control compared with chemotherapy-based treatment. Women in the prospective study group receive ribociclib plus endocrine therapy, with ovarian function suppression when clinically indicated. Their outcomes are compared with data from patients previously treated at the same participating hospitals with combination chemotherapy, with or without subsequent endocrine maintenance therapy. The main outcome is the objective response rate, defined as the proportion of patients whose tumors shrink or disappear. Other outcomes include progression-free survival, overall survival, clinical benefit, time to response, treatment safety, and quality of life.
