Regorafenib-pembrolizumab vs. TACE/TARE in Intermediate Stage HCC Beyond Up-to-7

Status: closed to accrual

REPLACE is a phase III, multicenter, randomized, open-label trial to evaluate the efficacy and safety of regorafenib and pembrolizumab (Rego-Pembro) versus transarterial chemoembolization (TACE) or transarterial radioembolization (TARE) for the first-line treatment of hepatocellular carcinoma (HCC or liver cancer). Approximately 496 patients in around 80 clinical sites worldwide will be randomized to receive either: - Investigational arm: Regorafenib in combination with pembrolizumab - Control arm: Transarterial chemoembolization (TACE) or transarterial radioembolization (TARE) In both arms, patients will receive trial treatment until progressive disease, unacceptable toxicity, deterioration of patient's condition that warrants permanent trial treatment discontinuation or other treatment discontinuation criteria is met. After trial treatment discontinuation, subsequent treatment will be administered according to the Investigator's clinical judgment.

Major surgical procedure, open biopsy, or significant traumatic injury ≤28 days prior to randomization.
Active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids.
Requirement of systemic treatment with either corticosteroids or other immunosuppressive medications ≤ 14 days prior to randomization.
Interstitial lung disease, non-infectious pneumonitis or uncontrolled lung diseases including pulmonary fibrosis, or clinically significant acute lung diseases.
Cardiovascular conditions as defined within the protocol.
Patient has a concurrent invasive malignancy or a prior invasive malignancy whose treatment was completed ≤ 2 years before randomization.

REPLACE is a phase III, multicenter, randomized, open-label trial to evaluate the

efficacy and safety of systemic therapy with Rego-Pembro versus loco-regional therapy

with TACE or TARE, for the first-line treatment of intermediate-stage HCC with beyond

up-to-7 criteria. Approximately 496 patients (~248 in each arm) from approximately 80

sites will be randomized in order to power the trial efficiently to measure a clinically

meaningful improvement for the primary endpoint, PFS according to mRECIST based on the

Investigator´s assessment.

The trial will include patients who have been diagnosed with intermediate-stage HCC by

biopsy, cytology or diagnostic imaging, such as dynamic computed tomography (CT) or

magnetic resonance imaging (MRI), according to the criteria of the American Association

for the Study of Liver Diseases (AASLD). Patients should have at least one measurable

lesion per RECIST 1.1, disease not amenable to curative treatment but amenable to

loco-regional therapy with TACE (cTACE or DEB-TACE) or TARE, ECOG PS 0-1, Child-Pugh

class A, and beyond up-to-7 criteria.

The trial will include the following phases:

- Screening

- Treatment

- Follow-up

Randomized patients will receive either:

Investigational arm (Arm A):

-Regorafenib at a dose of 90 mg orally q.d. on days 1 to 21 of a 4-week cycle.

In combination with:

-Pembrolizumab 400 mg using a 30-minutes i.v. infusion, on day 1 (D1) of a 6-week cycle.

Control arm (Arm B):

-Patients will be treated with TACE or TARE "on-demand" according to site's standard,

with the goal of controlling all known liver lesions.

In both arms, patients will receive trial treatment (Rego-Pembro or TACE/TARE) until PD

per mRECIST, unacceptable toxicity, deterioration of patient's condition that warrants

permanent trial treatment discontinuation or other treatment discontinuation criteria are

met.
