About this study

Official title: A Prospective, Single-Arm, Single-Center Exploratory Clinical Study of Stereotactic Body Radiation Therapy Combined With QL1706 in the Second-Line Treatment of Hepatocellular Carcinoma

This is a prospective, single-arm, single-center exploratory clinical study designed to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) combined with QL1706 in patients with hepatocellular carcinoma who have received one prior line of systemic therapy and experienced radiographic disease progression or intolerance.

Eligible patients will receive SBRT to all evaluable intrahepatic lesions at a total dose of 25-50 Gy delivered in 5 fractions. Within 7-14 days after completion of SBRT, patients will receive QL1706 at 7.5 mg/kg by intravenous infusion every 3 weeks. Treatment with QL1706 will continue until confirmed disease progression, intolerable toxicity, patient request to withdraw, withdrawal of informed consent, or other protocol-defined treatment discontinuation criteria, whichever occurs first.

The primary endpoint is objective response rate assessed by the investigator according to modified RECIST criteria. Secondary endpoints include local control rate of SBRT target lesions, progression-free survival, overall survival, disease control rate, and the incidence of adverse events and serious adverse events. Exploratory endpoints include dynamic changes in serum tumor biomarkers and immune-related indicators, as well as their association with clinical outcomes. A total of 36 patients are planned for enrollment.

Read the detailed description

This is a prospective, single-arm, single-center exploratory clinical study designed to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) followed by QL1706 in patients with hepatocellular carcinoma who require second-line treatment after one prior line of systemic therapy.

Patients with hepatocellular carcinoma who have received one prior line of systemic therapy and have experienced radiographic disease progression or intolerance may be enrolled if they meet all eligibility criteria. Eligible participants must have at least one measurable lesion according to modified RECIST, and all intrahepatic tumor lesions must be considered suitable for SBRT by the investigator. Patients with extrahepatic metastasis are not eligible.

All enrolled participants will receive SBRT to intrahepatic tumor lesions. SBRT will be delivered at a total dose of 25-50 Gy in 5 fractions, with 5-10 Gy per fraction. Radiation treatment planning will ensure that at least 700 cc of normal liver volume is preserved, with a mean radiation dose to this volume of no more than 15 Gy.

Within 7-14 days after completion of SBRT, participants will receive QL1706 at 7.5 mg/kg by intravenous infusion once every 3 weeks. QL1706 treatment will continue until confirmed disease progression, intolerable toxicity, patient request to withdraw, withdrawal of informed consent, initiation of new anticancer therapy, or other protocol-defined discontinuation criteria, whichever occurs first. Dose interruption or permanent discontinuation may be required based on individual safety and tolerability. Dose escalation or dose reduction is not recommended.

Tumor assessments will be performed at baseline, after completion of SBRT and before the first cycle of QL1706, and every 2 treatment cycles thereafter during study treatment. After treatment discontinuation, follow-up assessments, including survival follow-up, will be performed every 3 months where applicable.

The primary outcome measure is objective response rate assessed by the investigator according to modified RECIST. Secondary outcome measures include local control rate of SBRT target lesions, progression-free survival, overall survival, disease control rate, and the incidence of adverse events and serious adverse events. Exploratory outcome measures include dynamic changes in serum tumor biomarkers and immune-related indicators, and their association with clinical outcomes.

Approximately 36 participants are planned to be enrolled.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Stereotactic Body Radiation Therapy (SBRT)Radiation

    Also called SBRT, Stereotactic Ablative Radiotherapy

    SBRT will be delivered to all tumor lesions at a total dose of 25-50 Gy in 5 fractions, with 5-10 Gy per fraction.

  • QL1706Drug

    Also called Iparomlimab and Tuvonralimab Injection

    QL1706 will be administered at 7.5 mg/kg by intravenous infusion every 3 weeks, starting within 7-14 days after completion of SBRT. Dose interruption or permanent discontinuation may be required based on individual safety and tolerability. Dose escalation or dose reduction is not recommended.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Stereotactic Body Radiation Therapy (SBRT) and QL1706 in people with HCC - Hepatocellular Carcinoma, run by Hebei Medical University Fourth Hospital.

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 22 inclusion and 18 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: opening soon, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (time frame: up to 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Jun 2026.
