Official Title: A Pragmatic Randomized Phase III Trial Evaluating Total Ablative Therapy for Patients with Limited Metastatic Colorectal Cancer: Evaluating Radiation, Ablation, and Surgery [ERASUR]

A Study On:

Colon

Rectum

Study Description

This phase III trial compares total ablative therapy and usual systemic therapy to usual systemic therapy alone in treating patients with colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (IV) (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. Ablative means that the intention of the local treatment is to eliminate the cancer at that metastatic site. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. SABR, surgical resection, and microwave ablation have been tested for safety, but it is not scientifically proven that the addition of these treatments are beneficial for your stage of cancer. The addition of ablative local therapy to all known metastatic sites to the usual approach of systemic therapy could shrink or remove the tumor(s) or prevent the tumor(s) from returning.

Eligibility

You must have histologically-confirmed metastatic colorectal adenocarcinoma
No known microsatellite instable (MSI) tumor
Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression. No known peritoneal and/or omental metastases. If radiologic studies suggest the presence of peritoneal disease, a diagnostic laparoscopy is recommended to verify the absence of peritoneal implants
You must have primary tumor is already resected OR primary tumor is surgically amenable to resection, as determined by consultation and documentation with surgeon or documentation of discussion in the institutional multi-disciplinary tumor board where a surgeon confirms resectability. Patients with unresectable primary tumors are not eligible
Four (4) or fewer apparent sites of metastatic disease based on review by local medical team of baseline radiographic imaging obtained prior to initiation of systemic therapy.
You must not be pregnant and not nursing, because this study involves an agent or treatment that has known genotoxic, mutagenic, and teratogenic effects.
Age >= 18 years

In the instance of parental permission, “You” refers to “Your child.”

Please read the information below and ask questions about anything that you do not understand. A
researcher listed above will be available to answer your questions.

You are being asked to participate in a clinical research potential participant database to identify
potential clinical research studies you may be eligible for. Participation in this database is voluntary.
You may choose to skip any question. You may refuse to participate or discontinue your involvement
at any time without penalty or loss of benefits. You are free to withdraw from this database at any
time. If you decide to withdraw from this database you should notify the research team
immediately.

You are eligible to participate in this study if you may be interested in participating in a research trial at UCI Health

We would like to interview you to learn more about your eligibility for current clinical research studies at UCI. The interview will last about 5-30 minutes, depending on the extent of your medical history.

Possible risks/discomforts associated with the database are hearing about potential clinical research studies that may not be of interest to you, invasion of your privacy, or a potential breach of confidentiality.

There are no direct benefits from participation in the database. However, this database may help inform you on clinical research studies that you may be eligible for. Participation in UCI clinical research studies help us gain important data and knowledge that may lead to improved treatment options for people with similar conditions to you in the future.

There are no alternative procedures available. The only alternative is not to participate in this study.

There is no compensation for your participation in this database.

There is no cost to you for participation in this database.

All information collected will be stored confidentially in a world-class securely-hosted application, “RealTime CTMS,” with robust data protections and encryption. This application has HIPAA compliant architecture and application rules to ensure data privacy and regulatory compliance.

Researchers will use your information to assess your eligibility for current and future clinical research studies at UCI. You may opt out at any time.

The research team, authorized UCI personnel, and regulatory entities, may have access to your study records to protect your safety and welfare.

While the research team will make every effort to keep your personal information confidential, it is possible that an unauthorized person might see it. We cannot guarantee total privacy.

Future Research Use
Researchers will use your information to conduct this study. Once the study is done using your information, we may share them with other researchers so they can use them for other studies in the future. We will not share your name or any other private identifiable information that would let the researchers know who you are. We will not ask you for additional permission to share this de-identified information

Data Retention - In accordance with UC Office of the President policy, information will be retained for 10 years after the end of the calendar year in which the research is completed.

If, during the course of this study, significant new information becomes available that may relate to your willingness to continue to participate, this information will be provided to you by the research team listed at the top of the form.

If you have any comments, concerns, or questions regarding the conduct of this research please contact the researchers listed at the top of this form
