This prospective clinical trial aims to assess the feasibility, efficacy, and safety of a personalized radiofrequency ablation protocol coupled with complete biliary drainage for patients presenting with inoperable perihilar cholangiocarcinoma.
This clinical trial proposes a personalized treatment approach to inoperable perihilar cholangiocarcinoma consisting of endoluminal ablative therapy via radiofrequency ablation followed by endoscopic biliary drainage.
Patients presenting with jaundice / biliary obstruction caused by inoperable perihilar cholangiocarcinoma as assessed during multidisciplinary case discussion will be invited to enroll in this trial.
Patients will be randomized in a 1:1 fashion to receive biliary plastic stenting (control arm) or biliary plastic stenting + radiofrequency ablation via endoscopic approach. In cases where ERCP fails to achieve adequate biliary drainage, stenting and/or drainage will be attempted via percutaneous approach.
Additional systemic chemotherapy will be offered to all eligible patients according to the local standard of care.
Patients will be followed up with a clinical visit at 2 weeks and stent exchange (+ additional RFA treatment in the control arm) will be offered at 8-12 weeks interval until disease progression, clinical deterioration precluding ERCP or death.
The main study objectives are:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Endoscopic Drainage Arm | Active Comparator | Patients randomized to this arm will undergo biliary stenting only |
|
| COMBO-RFA Arm | Experimental | Patients randomized to this arm will undergo same-session endoluminal radiofrequency ablation followed by biliary stenting |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Endoluminal radiofrequency ablation | Procedure | Endoluminal Radiofrequency ablation (RFA) of the entire stricture length will be performed using the Habib probe. A current of 7W will be delivered for 90s intervals at a time. If multiple ablation sessions are needed in order to ablate the entire stricture lenght, there will be an overlap of ablated areas in order to ensure proper stricture treatment. Dilation of the stricture prior to RFA delivery will be performed if required. After RFA treatment, biliary drainage of all hepatic territories will be ensured. |
| Measure | Description | Time Frame |
|---|---|---|
| Technical success of ERCP procedure | Ability to correctly apply radiofrequency ablation and place stents in all the biliary ducts accessed on ERCP | 2 months |
| Tumor response | To evaluate the efficacy of radiofrequency ablation in local disease control by assessing tumor response according to RECIST criteria at 6 months follow-up | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of procedure-related adverse events | To evaluate the safety profile of the procedure by assessing the rate of procedure-related adverse events according to the ASGE lexicon (cholangitis, bleeding, perforation, pancreatitis) after endoscopic treatment | 12 months |
| Overall survival |
