What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Response Rate per modified RECIST 1.1

    The proportion of patients achieving a BOR of CR or PR per RECIST 1.1 among those that are evaluable for response.

    Measured: From Day 1 up to 3 years after first RP2 dose of last patient.

Secondary outcomes (3)

  1. Number of patients with treatment-emergent adverse events (TEAEs)

    The incidence of all TEAEs

    Measured: From Day 1 up to 135 days after last dose.

  2. ORR per RECIST modified for HCC (HCC mRECIST) for HCC cohort only

    The proportion of patients achieving a BOR of CR or PR per HCC-mRECIST among those that are evaluable for response

    Measured: From Day 1 up to 3 years after first RP2 dose of last patient

  3. Duration of response (DOR)

    The time from a tumor response, either a CR or PR (whichever is recorded first), until the date of PD, which was subsequently confirmed, or with no further follow up, or death due to any cause, whichever occurs first.

    Measured: From Day 1 up to 3 years after first RP2 dose of last patient.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RP2, Bevacizumab and Atezolizumab in people with Hepatocellular Carcinoma and Biliary Tract Cancer, run by Replimune, Inc. at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 41 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 2 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Clinical Trials at Replimune (1-781-222-9570, hccstudy@replimune.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate per modified RECIST 1.1 (time frame: From Day 1 up to 3 years after first RP2 dose of last patient.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05733598.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2026.
