Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

Researchers are investigating targeted therapies approved by the Food and Drug Administration FDA for patients with advanced cancers that have specific genetic changes. This study, called the Targeted Agent and Profiling Utilization Registry TAPUR Study, aims to understand how safely and effectively these targeted drugs work when prescribed in real-world settings for cancers with actionable genomic variants. The study also collects data on molecular testing choices and helps generate ideas for future clinical trials. Participants receive one of several FDA-approved targeted anticancer drugs, chosen based on specific genetic features of their tumors. These drugs include palbociclib, sunitinib, temsirolimus, trastuzumab with pertuzumab, vemurafenib with cobimetinib, regorafenib, olaparib, nivolumab with ipilimumab, abemaciclib, talazoparib, atezolizumab with talazoparib, tucatinib with trastuzumab, futibatinib, dabrafenib with trametinib, and fam-trastuzumab deruxtecan-nxki. Each treatment follows the approved dosing schedule and duration. Different genetic alterations qualify patients for different drugs, and the study covers a wide range of tumor types, including advanced solid tumors, multiple myeloma, and non-Hodgkin lymphoma. During the study, participants undergo regular assessments including physical exams and imaging tests to measure tumor response using standard criteria. The main outcome measured is the percentage of patients with tumor shrinkage or stable disease after 16 weeks of treatment. Researchers also monitor overall survival for up to three years. Safety and organ function are closely tracked through laboratory tests. Participants must provide informed consent and meet specific eligibility criteria, including measurable disease and acceptable organ function. The study does not use random assignment, and results are shared publicly as they become available and at study completion.
