A Study of Response to Standard Treatment Before Surgery in People With Rectal Cancer
What this study is about
The purpose of the study is to learn more about how the body responds to standard treatment (chemoradiation and chemotherapy).
View original scientific description
The purpose of the study is to learn more about how the body responds to standard treatment (chemoradiation and chemotherapy). The study will use the results of testing down on participants' blook, tissue, and scans to learn more about how people with rectal cancer respond to chemoradiation and chemotherapy treatment and if it is useful for predicting whether a person's cancer get better, gets worse, or stats the same after treatment.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 18 years of age or older on day of signing informed consent.
- Have a histologically confirmed diagnosis of invasive adenocarcinoma of the rectum with no known mismatch repair deficiency or Her2 amplification.
- Eligible for and plan to initiate standard-of-care therapy with any of the following regimens:
- Induction fluoropyrimidine (capecitabine \[preferred\] or 5-FU) based chemoradiation
- With plan for consolidative CAPEOX, FOLFOX, or FOLIRINOX
- Woman with childbearing potential who are negative for pregnancy test (urine or blood) and who agree to use an effective contraceptive method. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant. Reliable contraception should be used from the time of screening and must be continued throughout the duration of treatment as per standard of care.
Exclusion criteria
- Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen.
- Patients with prior external beam radiation therapy to the pelvis or brachytherapy seed implantation of the prostate.
- Patients who are pregnant or breastfeeding.
- Men or women not using effective contraception.
- Patients with a contraindication to MR imaging.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
