Percutaneous ablation (PA) is the only non-surgical curative treatment of hepatocellular carcinoma (HCC). Due to its excellent tolerance, particularly in patients with portal hypertension or bearing comorbidities, it now represents in France nearly 70% of the first-line curative treatment of "in Milan" tumours. For HCC less than 3 cm, ideal indication for percutaneous ablations, results of monopolar radiofrequency ablation (mRFA), are excellent with only 5% of reported non-tumoral control after a first procedure .
In addition to mRFA the arsenal of ablations has grown considerably with the emergence of new techniques. They allow the expansion of indications for PA, especially in patients with poor prognostic tumors or relatively advanced beyond the Milan criteria . In this setting, multibipolar mode using no touch technique (mbpRFAnt) increases the tumour volume that can be ablated, allowing the removal of large tumors> 5 cm . Furthermore, electroporation (EP) is a new PA technique that does not promote thermoablation but induce tumoral cells apoptosis and is particularly interesting for difficult-to-treat lesions located near vascular or biliary trunks . Inadequate tumour control is then de facto greater in these situations, around 20% at one year.
The idea of optimizing HCC curative treatments using neoadjuvant or adjuvant biotherapy, particularly in patients with advanced tumors in curative intent, is particularly attractive. One trial in adjuvant setting was conducted, the STORM trial, that tested the benefit of sorafenib in curative intent of in Milan HCC. This negative trial included patients with in Milan HCC, with an expected low rate of recurrence with only few patients treated by PA.
In parallel, the development of new molecules for HCC treatment, especially immunotherapy, seems to give promising results in palliative setting . Furthermore, PA procedures and most likely electroporation induce T-cell recruitement that may foster immunomodulation .
Neoadjuvant and adjuvant trials using these new molecules must now be cautiously designed based on the rigorous selection of special populations and therapeutic indications.
This project proposes a Phase 2 trial testing the safety and efficacy of treatment with Nivolumab in neoadjuvant and adjuvant setting in patients with advanced HCC treated by electroporation in curative intent.
|Condition or disease||Intervention/treatment||Phase|
|Hepatocellular Carcinoma||Drug: Nivolumab Injection [Opdivo]||Phase 2|
Multicenter (6 centers), Phase 2 trial.
-Inclusion visit The inclusion visit takes place between 15 days and no later than 3 days before the patient's hospitalization for Neoadjuvant therapy
Eligible patients will receive :
- 2 nivolumab infusions in a neoadjuvant setting (every 15 days) The treatment will be carried out every 2 weeks s, for 2 cycles before EP procedure The patient is hospitalized one day for treatment
- EP procedure performed in a curative attempt EP procedure will be performed according to previously described procedure in the setting of routine management of HCC as decided in multidisciplinary boards in each centre.
- 12 nivolumab infusions in an adjuvant setting (every 30 days) during one year. The patient is hospitalized one day for infusion
- Classical follow-up during an additional year (every 3 months) Follow up after adjuvant therapy (M12-M24) The usual evaluation will be performed every 3 months
Constitution of a biobank with :
- paraffin and frozen tumoral and non tumoral biopsy sampled at before and after one month of neoadjuvant Nivolumab (second biopsies at the time of the electroporation procedure)
- Serum samples and Peripheral blood mononuclear cells (PBMC) before and after one month of neoadjuvant Nivolumab then after EP at 1, 3, 6, 9 and 12 months after procedure.

- Local recurrence-free survival during a 2-years follow-up after Nivolumab neoadjuvant/adjuvant therapy and EP procedure [ Time Frame: At 2 years ]Recurrence rates (whether local or distant) will be assessed using imaging techniques as recommended by international guidelines (3-months US and MRI during two years). Patients who will meet primary endpoint will be alive 2 years after EP procedure without evidence of local recurrence on 3-months US/MRI evaluations.
- Changes of tumorous and non-tumorous perfusion parameters observed with CUS and MRI after one months of neoadjuvant treatments [ Time Frame: after one month of neoadjuvant treatment ]Evaluation performed by CUS and MRI
- Per nodule rates of early response [ Time Frame: At one month after a single procedure of EP ]Evaluation performed by MRI
- Incidences of intra segmental/ extra segmental distant recurrence [ Time Frame: During follow-up (2 yrs) ]Evaluation performed by MRI
- Assessment of overall survival [ Time Frame: At 2-yrs following EP procedure ]patients will meet this endpoint if they are alive with or without HCC recurrence 2 years after EP. procedures. Causes and date of death will be specified when applicable during this timeframe.
- Assessment of tolerance of the immunotherapy treatment: [ Time Frame: During follow-up (2 yrs) ]Adverse events related to Nivolumab infusions will be monitored according to manufacturer guidelines and recommendation.
- Compliance to neoadjuvant treatments [ Time Frame: During follow-up (13 months) ]Respect of scheduled Nivolumab infusions
- Compliance to adjuvant treatments [ Time Frame: During follow-up (13 months) ]Respect of scheduled Nivolumab infusions
- Frequency of SAEs [ Time Frame: During follow-up (2 yrs) ]adverse events related to Nivolumab infusions will be monitored according to manufacturer guidelines and recommendation.
- Frequency of discontinuations treatment due to AEs [ Time Frame: During follow-up (2 yrs) ]adverse events related to Nivolumab infusions will be monitored according to manufacturer guidelines and recommendation.
