About this study

PRELUDE-1 study is a pilot intervention trial that aims to describe the immunologic and genetic evolutions induced by stereotactic body radiationtherapy (SBRT) treatment in oligometastatic Colorectal Cancer (omCRC) patients with two-three nodules lung-limited disease.

Read the detailed description

PRELUDE-1 study is a monocentric pilot interventional trial. The study concerns all patients enrolled with a diagnosis of oligometastatic Colorectal Cancer (omCRC) with two-three nodules lung-limited disease and treated with SBRT technique. SBRT will be delivered according to a risk-adapted protocol.

Tumor genetic background will be assessed on primary FFPE (Formalin Fixed Paraffin Embedded) tissues. Liquid biopsy will be done on blood samples collected before radiotherapy (RT) start and after 40 days to monitor tumor DNA evolution. The most direct method to assess cancer genetics relies on sampling of tumor DNA and its characterization through whole genome sequencing techniques (NGS, Next Generation Sequencing).

The study will last 48 months, divides as follow: 24 months of enrollment phase and up to 24 months of follow-up. Follow-up will be performed on the 40th day after the end of radiation treatment and then every 3 months until progression.

What is being measured

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

  1. To assess the efficacy of SBRT in inducing a regressive genetic trajectory of KRAS gene (evaluated by NGS technique) after SBRT treatment.

    A genetic regressive trajectory is defined as KRAS mutated (any mutation) before SBRT and wild-type after SBRT (mutKRAS before SBRT→wtKRAS after SBRT). The sample size of the study is planned on this genetic trajectory, assuming a frequency of the phenomenon of 1/130 (as desumed from literature review). To be exhaustive, other realistic combinations are: wtKRAS→wtKRAS; mutKRAS→mutKRAS; wtKRAS→mutKRAS. Other assumptions for sample size calculation are: an alpha value of 0.05; a priori successful events rate of 0.077; 1-beta=0.60.

    Measured: 40 days after the end of RT

Secondary outcomes (6)
  1. To evaluate the response according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria, version 1.1 including any eventual abscopal effect.

    Measured: Up to 24 months after the end of RT

  2. To evaluate the responses' duration (measured from the time of documented objective response until documented tumor progression).

    Measured: Up to 24 months after the end of RT

  3. To evaluate the progression-free (PFS) survival (from the data of treatment start untill progression).

    Measured: Up to 24 months after the end of RT

  4. The toxicity, which will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE) of the National Cancer Institute, version 5.0, November 27, 2017.

    The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline. Higher scores mean worse outcome.

    Measured: Up to 24 months after the end of RT

  5. Tumor immune microenvironment in primary tumour

    Evaluate the tumor immune microenvironment (in particular the number of CD3+/CD8+/Granzyme B+ lymphocytes) of primary CRCs by immunohistochemistry (IHC).

    Measured: 40 days after the end of RT

  6. Metabolic response (exploratory studies)

    Assess the value of metabolic response by FDG-PET (fluorodeoxyglucose positron emission tomography) through SUV (Standardized Uptake Value) percentage modifications [(SUV after SBRT-SUV before SBRT/SUV before SBRT)x100].

    Measured: 40 days after the end of RT

Questions about this trial

What is this clinical trial studying?

A study testing Stereotactic Body Radiation Therapy (SBRT) in people with Colorectal Cancer Metastatic, run by National Cancer Institute, Naples at 1 site in Italy.

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 7 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 7 Nov 2024. 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 Italy. 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.

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 Paolo Muto, MD (0815903398 ext. +39, p.muto@istitutotumori.na.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the efficacy of SBRT in inducing a regressive genetic trajectory of KRAS gene (evaluated by NGS technique) after SBRT treatment. (time frame: 40 days after the end of RT). 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 7 Nov 2024.
