About this study

Official title: A Phase II, Open-Label Trial of S-Adenosylmethionine (SAMe) in Prevention of Oxaliplatin Associated Liver Injury

This is an open-label, phase II study that may provide evidence that taking S-adenosylmethionine (SAMe) supplementation prevents oxaliplatin, a type of chemotherapy drug, associated liver toxicity in patients with resectable colorectal liver metastases. Resectable means that it is able to removed with surgery. Patients will take two SAMe tablets in the morning and one tablet in the evening for 3-6 months (about 6-8 cycles of chemotherapy) in addition to oxaliplatin based chemotherapy followed by surgical removal of the colorectal liver metastases.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the efficacy of SAMe in preventing oxaliplatin associated liver injury as determined by lack of injury on histopathologic analysis in patients with liver only stage IV colorectal cancer.

    To identify the effect of SAMe in preventing oxaliplatin associated liver injury as determined by lack of injury on histopathologic analysis in patients with liver only stage IV colorectal cancer. Improvement in liver injury will be measured by the degree/histopathologic grade of liver injury utilizing the Combined Vascular Injury (CVI) Score in non-cancerous liver tissue post therapy compared to historical controls. CVI score will evaluate and grade sinusoidal dilation, small vessel loss/obliteration, focal hepatocyte plate disruption, parenchymal extinction lesions, nodular regenerative hyperplasia, peliosis, and veno-occlusive like changes. Rate of sinusoidal obstruction syndrome (SOS), as measured by CVI Score, ranging from 0-13. A CVI score of 3 or more indicates SOS. Compared to historical controls.

    Measured: 8 months

Secondary outcomes (6)

  1. To Estimate the Objective Response Rate (ORR) of SAMe when taken with oxaliplatin based chemotherapy.

    To evaluate the efficacy of SAMe during oxaliplatin based therapy in stage IV liver-only colorectal cancer, Objective Response Rate (ORR) will be measured by the proportion of patients with confirmed complete response (CR) or partial response (PR) per RECIST 1.1. ORR will be assessed from screening until EOT.

    Measured: 8 months

  2. To evaluate changes in average estimated blood loss (EBL) in patients undergoing liver resection as compared to historical controls.

    Calculate surgical EBL in all patients undergoing resection

    Measured: 8 months

  3. To evaluate length of hospital stay (LOS) in patients undergoing liver resection as compared to historical controls.

    Length of hospital stay (LOS) to historical controls, the following will be conducted:

    ii. Calculate hospital LOS in all patients undergoing resection iii. Account for 30-day readmission

    Measured: 8 months

  4. To examine if SAMe can decrease treatment-delays in oxaliplatin-based chemotherapy.

    Incidence of oxaliplatin treatment delays will be evaluated by recording the following: If treatment delay occurred and time point/duration of treatment delay

    Measured: 8 months

  5. To examine if SAMe can decrease dose-reductions in oxaliplatin-based chemotherapy.

    Incidence of oxaliplatin dose reduction will be evaluated by recording the following: If dose reduction occurred and time point of occurrence

    Measured: 8 months

  6. To evaluate safety and tolerability of SAMe in combination with SOC oxaliplatin based systemic therapy.

    Safety and tolerability of the combination will be evaluated by determining the proportion of patients with treatment-related adverse events of all grades as graded per CTCAE v.5, from first dose of study drug until 30 days post last dose of study drug.

    Measured: 8 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing S-adenosylmethionine (SAMe) supplement and Surgery in people with Colorectal Cancer and Liver Metastases, run by Cedars-Sinai Medical Center at 2 sites 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 14 inclusion and 25 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: opening soon, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Clinical Trial Navigator (310-423-5842, GroupCancerTrialInformation@cshs.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the efficacy of SAMe in preventing oxaliplatin associated liver injury as determined by lack of injury on histopathologic analysis in patients with liver only stage IV colorectal cancer. (time frame: 8 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06258525.

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.
