Epidemiological Study to Monitor Study Participants With Resected Stage II (High Risk) or Stage III Colorectal Cancer for Circulating Tumor DNA Before, During and After Their Treatment With Adjuvant Chemotherapy
United States, Belgium, Germany2,079 participantsStarted 2021-07-02
Plain-language summary
This is a multi-site epidemiological study designed to monitor circulating tumor DNA (ctDNA) status in participants with Stage II (high risk)/III colorectal cancer (CRC) following resection/prior to adjuvant chemotherapy (AdCTx), during the course of AdCTx and for a period of up to 630 days (21 months) thereafter, according to CRC stages and disease characteristics.
Participants receive no therapeutic intervention as part of this study. This study will identify participants with confirmed Stage II (high risk)/III CRC that are positive for ctDNA after resection who might be potential candidates for the clinical study BNT122-01 (NCT04486378), a study of RO7198457 after completion of standard adjuvant chemotherapy in this patient population. These participants will have the option to enter screening for BNT122-01 at Screening Visit 2 of that study if they meet the eligibility criteria of BNT000-001 during screening. Data from the assessments from this study (BNT000-001) will be carried across to the BNT122-01 study where feasible.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Must have given informed consent indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
* Age ≥ 18 years old at time of signing the informed consent form.
* Ability to comply with the study protocol, in the investigator's judgment.
* Must have Stage II/Stage III rectal cancer or Stage II (high risk)/Stage III colon cancer per AJCC 2017 that has been surgically totally resected (R0 confirmed by pathology report). Stage II (high risk) colon cancer is defined as (any of):
* T4
* Grade ≥ 3
* Clinical presentation with bowel obstruction or perforation
* Histological signs of vascular, lymphatic or perineural invasion
* \< 12 nodes examined
* Adequate tumor material in formalin-fixed paraffin embedded blocks or as sectioned tissue (only upon approval by sponsor) must be available, preferably from resection. The specimen should be submitted along with an associated pathology report. Multiple samples may be provided as available, but priority should be given to tissue with the highest tumor content and lowest necrotic area.
* Intention to receive a standard of care AdCTx within 8 weeks post-surgery, and be scheduled for at least 3 months of treatment (including rest days) according to the treating physician or investigator.
* Eastern Cooperative Oncology Group Performance Status of 0 or 1.
* Adequate end-organ function.
Exclusion Criteria:
* Neo-adjuvant (radio)chemotherapy …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Occurrence of ctDNA positivity in the post-surgery/pre-AdCTx blood sample
Timeframe: 4 to 8 weeks (28 to 56 days) after surgery and within 7 days prior to start of AdCTx
