Prospective study in patients with colon or rectum cancer with liver metastasis of the efficacy and toxicity of standard therapy (chemotherapy + targeted therapy) combined with immunotherapy and internal radiotherapy targeting the liver
EU CTIS ID: 2024-517204-11-00
What this study is testing
evaluate the progression-free survival at 9 months (according to RECIST 1.1) according to the investigator.
- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- age over 18 years old
- adequate hematological function
- adequate hepatic function
- adequate renal function
- patient affiliated to a social security system information provided to patient and signature of the informed consent form by patient and the investigator
- histologically proven mismatch repair proficient metastatic colorectal cancer (pMMR and/ or MSS)
You likely can't join if
- active infection still requiring intravenous antibiotics on the first scheduled day of protocol treatment
- Severe chronic liver failure, which in the investigator's opinion would not allow SIRT to be received safely
- - Active hepatitis B or hepatitis C. 1 - If patient has HBV, meets the following criteria as applicable to the infection type to be eligible: for patients with inactive/asymptomatic carrier, chronic, or active HBV: HBV DNA < 500 IU/mL (or 2500 copies/mL) at screening. Patients with detectable hepatitis B surface antigen (HBsAg) or detectable HBV DNA should be managed per treatment guidelines. Patients receiving antivirals at Screening should have been treated for > 2 weeks prior to enrollment and should continue treatment on study. 2 - For patients with HCV : to be eligible, patients with detectable HCV RNA should remain on continuous, effective antiviral therapy during the study
- Active tuberculosis
- Patient with contraindication to angiography and selective hepatic catheterization such as bleeding diathesis or coagulopathy with serious bleeding risk that is not correctable by usual therapy of hemostatic agents.
- Patients on anticoagulant therapy different from low-molecular-weight heparin (LMWH) cannot be included (i.e. VKA and NOACs). Relaying these anticoagulants to a LMWH before inclusion is allowed. In addition, it must be possible to stop the LMWH 24 hours before invasive procedures according to the usual recommendations (before the work-up and before the SIRT).
