Oral Green Tea Extract and Milk Thistle Extract to Colorectal Cancer Patients Undergoing Resection
A Phase 1 study testing Green Tea and Milk Thistle Supplements in people with Colon Cancer, run by Richard Whelan at 1 site in United States.
Trial summary
Colorectal cancer is the third most common form of cancer found in the United States. To date surgical resection provides the best chance for cure. Unfortunately, despite "curative" surgery, tumor recurrences develop in 30-40% of patients from either unforeseen residual metastases or from viable tumor cells shed into… Read more about this study

About this study
Official title: Perioperative Administration of Oral Green Tea Extract/Milk Thistle Extract to Colorectal Cancer Patients Undergoing Colorectal Cancer Resection, a Phase 1 Study
Colorectal cancer is the third most common form of cancer found in the United States. To date surgical resection provides the best chance for cure. Unfortunately, despite "curative" surgery, tumor recurrences develop in 30-40% of patients from either unforeseen residual metastases or from viable tumor cells shed into the circulation before or at the time of surgery. There is evidence from both humans and mice suggesting that tumor growth is stimulated after surgery for a period of time.
This study calls for the administration of a green tea extract and a milk thistle extract, two orally ingested supplements, during the week immediately before and weeks after your surgery. It is not the current standard of care to give anti-cancer drugs during the perioperative period. The basic idea behind this study is that it should be beneficial to inhibit cancer growth in the days leading up to and following surgery. Why is this the case?

It makes sense to limit or inhibit tumor growth before surgery with drugs provided it can be done safely and does not interfere with the surgery. It is also logical to give anti-cancer drugs after surgery because, unfortunately, about 35 percent of colorectal cancer patients, after resection, have hidden tumor cells that remain in the body. There is also strong human evidence that tumor growth is stimulated during the first month after tumor resection as a result of the surgical injuries and the healing process. Therefore, there is good reason to give anti-cancer drugs as soon as possible after surgery in order to offset some of surgery's negative effects.
Although both supplements have been given safely to a wide variety of patients with a number of different medical problems, the two supplements together have never been given to cancer patients during the weeks just before and following surgery. The researchers hypothesize that the administration of these two supplements together will be safe in the period surrounding colorectal cancer surgery.
Read the detailed description
Green tea extract and Silibinin (from the milk thistle plant) have both been shown in experimental studies to have anti-cancer effects as well as limited toxicity. Epigallocatechin-3-gallate (EGCG) is the major active catechin in green tea; it has been shown to prevent and limit tumor growth in murine models1-3. Silymarin, which is extracted from the seeds of the milk thistle plant, is used clinically as a hepatoprotective agent in Europe4. Its major active component, Silibinin, is well-tolerated and largely free of adverse effects5-6. In recent studies, Silibinin has been shown to inhibit the growth of a number of cancers in mouse models, including lung7, bladder8, liver9, prostate10, and colon11-12. Silibinin and EGCG have similar anti-neoplastic mechanisms including: 1) cell cycle arrest via upregulation of P21 and P27 and downregulation of CDK, 2) induction of apoptosis via Caspase-3 activation and cleavage of poly (ADP-ribose) polymerase (PARP), and 3) suppression of angiogenesis and metastasis via inhibition of vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP-9)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Green Tea and Milk Thistle Supplements in people with Colon Cancer, run by Richard Whelan at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 22 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with adverse events or complications (time frame: 60 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2023.
