Metastatic Adenoid Cystic Carcinoma

The goal of this study is to treat patients with NOTCH active advanced adenoid cystic carcinoma (ACC) tumors with a combination or two different oral medications to slow tumor growth and improve survival outcomes. The names of the study drugs involved in this study are: * CB-103 (an oral NOTCH pathway inhibitor) * Abemaciclib (CDK4/6 inhibitor) * Lenvatinib (a vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI))

The goal of this study is to determine the safety and antitumor effects of REM-422, a MYB mRNA degrader, in people with advanced Adenoid Cystic Carcinoma (ACC)

The aim of this study is to learn whether the early initiation of a specialized and focused type of radiation called stereotactic body radiation therapy (SBRT) will impact the progression of advanced adenoid cystic carcinoma, quality of life, and overall survival. The name(s) of the study intervention involved in this study is: * Stereotactic Body Radiation Therapy (SBRT)
