Amplitude-Modulated Radiofrequency Electromagnetic Fields (AM RF EMF) in Combination With Fruquintinib in Refractory Metastatic Colorectal Cancer

Recruiting now · Phase 2

Conditions studied: Metastatic Colorectal Adenocarcinoma

In brief

The goal of this clinical trial is to learn if adding amplitude-modulated radiofrequency electromagnetic fields (AM RF EMF) to Fruquintinib in metastatic colorectal cancer that has not responded to other standard treatment is: * Effective in improving survival * safe and tolerable

Who can join

Age: 22 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Participant must have histologically or cytologically confirmed metastatic colorectal adenocarcinoma. There must be previous documentation of RAS (Rat sarcoma mutation), BRAF (B-Raf proto-oncogene, Serine/threonine kinase), MSI/MMR (microsatellite instability, mismatch repair) , and HER2 (Human epidermal growth factor receptor 2) status.
Participant must have progressed on or been intolerant to the following previous treatments (if not contraindicated):
Fluoropyrimidine-, oxaliplatin-, or irinotecan-based chemotherapy
Anti-VEGF (vascular endothelial growth factor) biological therapy, such as bevacizumab, aflibercept, or ramucirumab
If RAS is wild type, an anti-EGFR (epidermal growth factor receptor) therapy like cetuximab or panitumumab
Participant must have evaluable disease as defined by the investigator using CT (computed tomography), MRI (magnetic resonance imaging), or PET (positron emission tomograph) scan.
Participant must have a body weight ≥ 40 kg.
Participant must be aged 22 years or older.
Participant must be able to understand a written informed consent document and be willing to sign it.
Participant must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
Participant must have adequate organ and marrow function within 14 days prior to the initiation of treatment as described below:
Participant should have an expected lifespan of >12 weeks as determined by the investigator.
Fruquintinib is suspected to cause loss of human pregnancy and impaired development of the embryo or fetus. Therefore, women of child-bearing potential must agree to avoid becoming pregnant and male participants should avoid impregnating a female partner starting at initiation of treatment up until at least 14 days after the last fruquintinib dose.

You may not qualify if…

Participants with uncontrolled hypertension per investigator discretion.
Participants with a history or presence of gastric/duodenal ulcer or ulcerative colitis, hemorrhage of an unresected gastrointestinal tumor, perforation, fistulas, or any other condition that could, in the investigator's judgment, result in gastrointestinal hemorrhage or perforation.
Participants with a history or presence of hemorrhage from any other site (i.e., lower GI bleed, hemoptysis or hematemesis) within two months prior to screening.
Participants with a history of a thromboembolic event, including deep vein thrombosis (DVT), pulmonary embolism (PE), or arterial embolism within three months prior to screening unless they are on a stable dose of anticoagulant and no further evidence of active thromboses are seen on CT scan or venous Doppler imaging. Participants with saddle (massive) pulmonary embolism that require thrombectomy/thrombolysis within 12 months of screening are excluded from the trial.
Participants with a history of stroke and/or transient ischemic attack within 12 months prior to screening.
Participants with clinically significant cardiovascular disease, including but not limited to acute myocardial infarction or coronary artery bypass surgery within six months prior to enrollment, severe or unstable angina pectoris, New York Heart Association Class III/IV congestive heart failure, ventricular arrhythmias requiring treatment, or previous left ventricular ejection fraction (LVEF) < 50% by echocardiogram.
Participants with corrected QT interval using the Fridericia method (QTcF) > 480 msec or any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in a first-degree relative.
Participants taking concomitant medications with a known risk of causing QT prolongation and/or torsades de pointes. (Source list is continuously updated online at www.crediblemeds.org.)
Participants taking systemic anti-neoplastic therapies four weeks prior to the first dose of study drug, including chemotherapy, biotherapy, or immunotherapy. Palliative radiation is allowed if it does not cover all evaluable disease.
Participants taking systemic small molecule targeted therapies (e.g., tyrosine kinase inhibitors) within five half-lives or four weeks, whichever is shorter, prior to the first dose of study drug.
Participants who have undergone major surgery within 30 days prior to the first dose of study drug or if they still have unhealed surgical incision from previous surgery.
Participants with any unresolved toxicities from a previous antitumor treatment greater than NCI CTCAE v5.0 grade 2.
Participants that have current drug or alcohol abuse.
Participants with known human immunodeficiency virus (HIV) infection are not eligible if their viral load and/or CD4 (cluster of differentiation 4) count are considered poorly controlled with anti-HIV therapy.
Participants with a known history of active viral hepatitis. For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated. Participants that test positive for hepatitis C virus (HCV) but are currently being treated are eligible if they have an undetectable HCV viral load.
Participants with clinically uncontrolled active infections requiring intravenous antibiotics.
Participants with tumor invasion of a large vascular structure (e.g., pulmonary artery, superior or inferior vena cava).
Participants with brain metastases and/or spinal cord compression untreated with surgery and/or radiotherapy and without clinical imaging evidence of stable disease for 14 days or longer.
Participants with known active secondary malignancy, unless, in the opinion of the investigator, it is unlikely to interfere with the safety and efficacy of the endpoints.
Participants that are unable to take medication orally including those with dysphagia or an active gastric ulcer resulting from previous surgery (e.g., gastric bypass) or severe gastrointestinal disease, or any other condition that the investigator believes may affect absorption of fruquintinib.
Participants with metabolic disorder that the investigator suspects may prohibit fruquintinib action, affect interpretation of study results, or put the participant at undue risk of harm based on the investigator's assessment.
Participants that have received prior fruquintinib treatment.
Participants with a known hypersensitivity to fruquintinib or any of its inactive ingredients including the azo dyes tartrazine, FD\&C yellow 5, and sunset yellow FCF.
Participants taking strong inducers or inhibitors of CYP3A4 within five half-lives or four weeks, whichever is longer, before the first dose of study drug. Refer to Appendix 2 for a comprehensive list of excluded medications related to CYP3A4.
Participants that are taking any other investigational drugs.
