A Study Evaluating the Safety and Efficacy of Targeted Therapies in Subpopulations of Patients With Metastatic Colorectal Cancer (INTRINSIC)
What this study is about
This where both patients and doctors know the treatment given, exploratory study is designed to evaluate the safety and effectiveness of targeted therapies or immunotherapy as single agents or combinations, in participants with metastatic colorectal cancer (mCRC) whose tumors are biomarker positive as per treatment treatment group$1-specific definition.
View original scientific description
This open-label, exploratory study is designed to evaluate the safety and efficacy of targeted therapies or immunotherapy as single agents or combinations, in participants with metastatic colorectal cancer (mCRC) whose tumors are biomarker positive as per treatment arm-specific definition. Eligible participants with mCRC will be enrolled into specific treatment arms based on their biomarker assay results.
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
- Signed cohort-specific Informed Consent Form
- Age \>= 18 years at time of signing Informed Consent Form
- Biomarker eligibility as determined by:
- A validated test approved by local health authorities for detection of the specified biomarkers/mutations.
- A validated test performed at a College of American Pathologists/clinical laboratory improvement amendments (CAP/CLIA) -certified or equivalently accredited diagnostic laboratory using a validated test for detection of the specified biomarkers.
- Prior test results completed before signing cohort-specific Informed Consent Form or local test results generated prior to or during screening, and availability of a full report of the testing results OR
- Blood-based FoundationOne Liquid CDx biomarker eligibility test result generated prior to or during screening or, in case of re-enrollment after treatment discontinuation, prior to starting a new anti-cancer therapy.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of \<= 1
- Life expectancy \>= 3 months, as determined by the investigator
- Histologically confirmed adenocarcinoma originating from the colon or rectum
- Metastatic disease
- Prior therapies for metastatic disease
- Ability to comply with the study protocol, in the investigators judgment
- Measurable disease (at least one target lesion) according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)
- Baseline tumor tissue samples will be collected from all participants for exploratory biomarker research
- Adequate hematologic and organ function within 14 days prior to initiation of study treatment
- For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures
- For men: agreement to remain abstinent or use contraceptive measures, and agreement to refrain from donating sperm
Exclusion criteria
- Current participation or enrollment in another interventional clinical trial. Participants who are participating in the follow-up period of an interventional clinical trial are eligible for the study.
- Any systemic anti-cancer treatment within 2 weeks or 5 half-lives (whichever is shorter) prior to start of study treatment
- Treatment with investigational therapy within 28 days prior to initiation of study treatment
- Pregnant or breastfeeding, or intending to become pregnant during the study
- History of or concurrent serious medical condition or abnormality in clinical laboratory tests that, in the investigator's judgment, precludes the patient's safe participation in and completion of the study or confounds the ability to interpret data from the study
- Severe infection within 4 weeks prior to initiation of study treatment or any active infection that, in the opinion of the investigator, could impact patient safety
- Incomplete recovery from any surgery prior to the start of study treatment that would interfere with the determination of safety or efficacy of study treatment
- Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures (once monthly or more frequently)
- Uncontrolled tumor-related pain
- Uncontrolled or symptomatic hypercalcemia
- Clinically significant and active liver disease
- Negative HIV test at screening, with the following exception: Participants with a positive HIV test at screening are eligible provided they are stable on anti-retroviral therapy for at least 4 weeks, have a CD4 count greater than or equal to 200/uL, have an undetectable viral load, and have not had a history of opportunistic infection attributable to AIDS within the last 12 months.
- Symptomatic, untreated, or actively progressing CNS metastases
- History of leptomeningeal disease or carcinomatous meningitis
- History of malignancy other than CRC within 2 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death
- Any other disease, unresolved toxicity from prior therapy, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the participant at high risk from treatment complications
- Requirement for treatment with any medicinal product that contraindicates the use of any of the study treatments, may interfere with the planned treatment, affects participant compliance, or puts the patient at higher risk for treatment-related complications

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.
