Short Course Radiation Therapy and Combination Chemotherapy for the Treatment of Stage II-III Rectal Cancer
This phase I trial investigates how well short-course radiation therapy followed by combination chemotherapy works in treating patients with stage II-III rectal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as leucovorin, fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving short-course radiation therapy and combination chemotherapy may reduce the need for surgery and therefore improve quality of life.

Financial Burden Assessment in Patients With Stage I-III Colon or Rectal Cancer Undergoing Treatment
This research trial studies the financial burden in patients with stage I-III colon or rectal cancer who are undergoing treatment. Collecting data from patients about their cost and quality of life may help doctors to better understand the impact of cancer treatment on a patient?s employment and finances.

Circulating Tumor Cells in Patients With Locally Advanced Rectal Cancer
This study looks at the level of circulating tumor elements (cancer cells or DNA pieces floating in the blood) and how it may be related to how the tumor responds to standard treatment in patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced). Researchers will also compare the level and genetic characteristics of circulating tumor elements between individuals with rectal cancer and healthy individuals to understand how they may change over time. Information from this study may help researchers better understand rectal cancer.

SX-682 and Nivolumab for the Treatment of RAS-Mutated, MSS Unresectable or Metastatic Colorectal Cancer, the STOPTRAFFIC-1 Trial
This phase Ib/II trial studies the side effects and best dose of SX-682 that can be given alone and in combination with nivolumab in treating patients with RAS-Mutated, microsatellite stable (MSS) colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). SX-682 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving SX-682 alone and together with nivolumab may kill more tumor cells.

LY3214996 and Cetuximab Alone or in Combination With Abemaciclib for the Treatment of Unresectable or Metastatic Colorectal Cancer
This phase Ib/II trial investigates the side effects and best dose of LY3214996 when given together with cetuximab alone or in combination with abemaciclib and to see how well they work in treating patients with colorectal cancer that cannot be removed by surgery (unresectable) and/or has spread to other places in the body (metastatic). Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. LY3214996 and abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving LY3214996 and cetuximab alone or in combination with abemaciclib may help treat patients with colorectal cancer.

An Investigational Scan (64Cu-Labeled M5A Antibody) in Combination With SOC Chemotherapy and Radiotherapy in Locally Advanced Rectal Cancer
This early phase I trial investigates how well 64Cu-labeled M5A antibody scan works in assessing tumor activity before and after patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) who are undergoing chemotherapy and radiotherapy. Using 64Cu-labeled M5A positron emission tomography imaging may play a significant role in imaging patients with colorectal cancer.

Active Surveillance and Chemotherapy Before Surgery in Treating Participants With Stage II-III Rectal Cancer
This pilot trial studies how well active surveillance and chemotherapy before surgery work in treating participants with stage II-III rectal cancer. Active surveillance involves monitoring participants for additional tumor growth after receiving cancer treatment. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether deferring surgery after active surveillance and chemotherapy will work better in treating participants with stage II-III rectal cancer.

TAS-102 With Concurrent Radiation for the Treatment of Untreated Resectable Stage II-III Rectal Cancer
This phase 1b trial studies the side effects and best dose of TAS-102 when given together with radiation therapy in treating patients with stage II-III rectal cancer that has not been treated and can be removed by surgery (resectable). Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. This study is being done to find out the safest dose of TAS-102 that can be used with radiation treatment for rectal cancer.

Establishing a ctDNA Biomarker to Improve Organ Preserving Strategies in Patients With Rectal Cancer
This study measures the levels of circulating tumor DNA (ctDNA) in patients with stage II-III rectal cancer before, during, and after treatment to find out if the presence or absence of ctDNA in patient's blood using the Signatera test can be used to gauge how different treatments may affect rectal cancer. ctDNA is DNA from the rectal cancer that is circulating in the blood. The purpose of this study is to understand if the way rectal tumors respond to standard treatment can be associated with varying levels of ctDNA.

Panitumumab, Regorafenib, or TAS-102, in Treating Patients With Metastatic and/or Unresectable RAS Wild-Type Colorectal Cancer
This phase II trial studies how well retreatment with panitumumab works compared to standard of care regorafenib or trifluridine and tipiracil hydrochloride (TAS-102) in treating patients with colorectal cancer that is negative for RAS wild-type colorectal cancer has spread to other places in the body (metastatic), and/or cannot be removed by surgery (unresectable), and is negative for resistance mutations in blood. Treatment with panitumumab may interfere with the ability of tumor cells to grow and spread. Some tumors need growth factors to keep growing. Growth factor antagonists, such as regorafenib, may interfere with the growth factor and stop the tumor from growing. Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab may work better in treating patients with colorectal cancer than with the usual treatment of regorafenib or TAS-102.
