Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Embolization

Active comparator: Portal Vein Embolization (PVE) alone - (control arm) - Portal Vein Embolization (PVE) alone

Experimental: Combined Portal and Hepatic Vein Embolization (PVE/HVE) - (interventional arm) - Combined Portal and Hepatic Vein Embolization (PVE/HVE) - (interventional arm)


Treatment: Surgery: Embolization
Portal Vein embolization with Glue by a transhepatic approach vs. PVE and Hepatic Vein Occlusion with Vascular plugs via a transjugular or transfemoral approach in the same session as the PVE procedure

Eligibility
Key inclusion criteria
* Patients with primarily unresectable/ potentially resectable CRLM with a FLR <30% (<40% in chemotherapy damaged livers)
* Patients with non-resected primary CRC may be included if there is an intention to resect the CRC after the liver treatment (liver first approach) or simultaneously during one of the liver procedures.
* Patients with resectable or ablatable lung or brain metastases can be included (statement about the resectability of these extrahepatic metastases by a tumor board needs to be available)
* 18 Years and older
* Men and women
* Able to understand the trial and provide informed consent.
Minimum age
18 Years
Maximum age
No limit
Sex

Can healthy volunteers participate?
No
Key exclusion criteria
* Pregnant or lactating female.
* Premenopausal females not able or willing to commit to oral contraception
* Patients with prohibitive comorbidities, decision made by local team
* Any patient with non-resectable or non-ablatable extrahepatic disease
* Patients with hepatic malignancies other than CRLM
* Progression of disease by RECIST criteria after cytoreduction chemotherapy
* Complete response after conversion chemotherapy
* Staging CT and (if indicated) CT/MRI brain that demonstrates non-resectable extrahepatic disease
* The anatomy of the liver or manifestation of tumors in relation to the liver veins prohibits the use of combined PVE/HVE.
