What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying a treatment for Metastatic Colorectal Cancer, which is a type of cancer that has spread from the colon or rectum to other parts of the body. The study is investigating a new treatment combination that includes a medication with the code name SCO-101 and a chemotherapy regimen known as FOLFIRI. FOLFIRI is a combination of drugs that includes Fluorouracil, Irinotecan Hydrochloride, and Disodium Folinate. The purpose of the study is to determine the safety and effectiveness of this new treatment combination in patients whose cancer has become resistant to FOLFIRI.

Participants in the study will receive the treatment over a period of time, with regular monitoring to assess how well the treatment is working and to check for any side effects. The study will help researchers understand the best dose of SCO-101 when used with FOLFIRI and how well this combination can control the cancer. The treatment will be given in cycles, and the response to the treatment will be evaluated using imaging techniques like MRI or CT scans to see if the cancer is shrinking or stable.

The study aims to provide valuable information on whether this new combination can be a safe and effective option for patients with advanced colorectal cancer that has not responded to standard treatments. By participating in this study, researchers hope to find a new way to manage this challenging condition and improve outcomes for patients in the future.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial treatment phase

    The trial begins with the administration of the combination treatment, which includes SCO-101 and FOLFIRI. FOLFIRI is a chemotherapy regimen that includes fluorouracil, irinotecan hydrochloride, and disodium folinate.

    The treatment is administered in cycles. Each cycle consists of intravenous infusions of the medications. Fluorouracil is given as an injection with a concentration of 25 mg/ml. Irinotecan hydrochloride is provided as a concentrate for infusion at 20 mg/ml.

    The oral medication SCO-101 is taken in tablet form. The dosage and frequency are determined based on the maximum tolerated dose identified during the trial.

  2. Step 2

    Monitoring and assessment

    Throughout the trial, regular monitoring is conducted to assess the safety and tolerability of the treatment. This includes evaluating any adverse effects experienced during the treatment period.

    The effectiveness of the treatment is assessed using imaging techniques such as CT scans or MRIs. These assessments help determine the response of the cancer to the treatment.

  3. Step 3

    Dose adjustment

    Based on the initial response and any side effects, adjustments to the dosage of SCO-101 may be made to ensure the maximum tolerated dose is not exceeded.

    The goal is to find a balance between minimizing side effects and maximizing the treatment's effectiveness.

  4. Step 4

    Evaluation of treatment response

    After 20 weeks from the start of the treatment, an evaluation is conducted to assess the objective response rate. This involves determining the extent of tumor reduction or stabilization.

    The criteria used for this evaluation are based on standardized guidelines for measuring tumor response.

  5. Step 5

    End of treatment and follow-up

    The treatment phase concludes after the specified duration, and a follow-up period begins. This involves continued monitoring for any delayed side effects and assessing the long-term effectiveness of the treatment.

    The follow-up period also includes additional imaging studies to track the progression of the disease.

    • Must have signed the informed consent form.
    • Eligible only if no other standard treatment options are available, meaning:
      • They have not responded to all available standard treatments, and/or
      • They cannot tolerate all remaining standard treatments, and/or
      • They choose not to undergo any other standard treatments, and/or
      • Their doctor believes no further standard treatment can be offered for their cancer.
      • Must be 18 years or older.
      • Must have a confirmed diagnosis of colorectal adenocarcinoma, a type of colon cancer.
      • Must have non-resectable metastatic colorectal cancer (mCRC), meaning the cancer cannot be surgically removed. Specific genetic mutations may be present or absent depending on the study stage.
      • Must have previously been treated with certain chemotherapy drugs, including irinotecan and 5-FU, and shown disease progression.
      • Must have had a maximum reduction of 33% in the previous dose of FOLFIRI, a chemotherapy regimen.
      • Must have been treated with an oxaliplatin-containing regimen and not be suitable for further treatment with oxaliplatin.
      • For certain stages of the study, must have disease that can be evaluated or measured by CT scan or MRI.
      • Must have a performance status of ECOG 1 or less, which means they are fully active or have some symptoms but do not require bed rest.

Investigated drugs

  • SCO-101

    is an experimental medication being studied for its potential to enhance the effectiveness of cancer treatments. In this trial, it is being tested to see if it can help treat patients with advanced colorectal cancer who have not responded to standard treatments. Researchers are looking at how safe it is to use and what side effects it might cause when combined with other cancer drugs.

  • FOLFIRI

    is a combination of cancer-fighting drugs used to treat colorectal cancer. It includes a mix of medications that work together to stop cancer cells from growing and spreading. In this trial, FOLFIRI is being used alongside SCO-101 to see if the combination can be more effective in treating patients with advanced colorectal cancer.

What is already known about the treatment

SCO-101 – SCO-101 is administered orally and is currently being studied in clinical trials for its potential use in treating metastatic colorectal cancer. It is being evaluated for its safety, tolerability, and effectiveness when used in combination with the chemotherapy regimen FOLFIRI. The main therapeutic indication for SCO-101 is to enhance the treatment of colorectal cancer that has become resistant to standard therapies. At the molecular level, SCO-101 is believed to work by modulating specific cellular pathways that contribute to cancer cell survival and resistance. It is classified pharmacologically as a chemosensitizer, which means it is designed to make cancer cells more sensitive to chemotherapy.

Investigated diseases

Metastatic Colorectal Cancer – This is a type of cancer that originates in the colon or rectum and has spread to other parts of the body, such as the liver or lungs. The disease typically begins as a growth, called a polyp, on the inner lining of the colon or rectum, which can become cancerous over time. As the cancer progresses, it can invade nearby tissues and organs, and eventually spread to distant sites through the bloodstream or lymphatic system. The progression of metastatic colorectal cancer can vary, with some patients experiencing rapid spread, while others may have a slower progression. Symptoms may include changes in bowel habits, blood in the stool, abdominal pain, and unexplained weight loss. The disease is often diagnosed at an advanced stage due to the lack of early symptoms.
