Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

An open label 1:1 randomized phase II exploratory study investigating use of ctDNA-guided adjuvant chemotherapy compared to standard of care (SOC) after local treatment for metastatic colorectal cancer.

Patients are randomized 1:1 between SOC and ctDNA guided treatment and follow-up.

Escalation therapy comprises standard regimen of Fluorouracil (5-FU), Irinotecan and oxaliplatin (FOLFOXIRI), de-escalation therapy of monotherapy capecitabine or observation only. SOC is per institutional practice, based on national guidelines.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: A: Standard of care
Standard decision making regarding adjuvant chemotherapy with fluoropyrimidine and oxaliplatin as per institutional standards.
Other: Standard of care
Patients will be offered adjuvant chemotherapy according to standard of care. Follow up will be performed with imaging according to standard guidelines, equal to the experimental arm. Blood samples will be analyzed retrospectively to evaluate the ctDNA status.
Experimental: B: ctDNA guided therapy approach
Post ablation ctDNA results will be used for treatment decision.
Other: Circulating tumor DNA guided treatment approach
Circulating tumor-marker positivity will lead to escalation with 6 months of intensified chemotherapy consisting of 4 months of FOLFOXIRI followed by 2 months of 5FU monotherapy. Circulating tumor-marker negativity will based on shared decision-making lead to de-escalation i.e. possibilities for observation in patients otherwise eligible for monotherapy or observation/monotherapy in patients, otherwise eligible for combination chemotherapy according to standard of care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Quality of life according to EORTC QLQ-CR29 and -C30
Time Frame: 5 years last patient
The EORTC QLQ-CR29 is a tumor-specific health related QoL questionnaire module for CRC patients, which complement the EORTC QLQ-C30 questionnaire. Patients indicate their symptoms during the past week(s). Scores can be linearly transformed to a score from 0-100. Higher scores represent better functioning on the functional scales and a higher level of symptoms on the symptom scales.
5 years last patient
Quality of life according to EQ-5D-5L
Time Frame: 5 years last patient
The EQ-5D-5L essentially consists of: the EQ-5D descriptive system and the EQ visual analogue scale. The descriptive system comprises 5 dimensions. Each dimension has 5 levels. The patient is asked to indicate his/her health. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the 5 dimensions can be combined into a 5-digit number that describes the patient's health state.The EQ VAS records the patient's self-rated health on a vertical visual analogue scale.
