HAIC Combined With Adebrelimab Plus Apatinib as the First-line Treatment for HCC in BCLC Stage C: An Open-label, Single-arm, Phase II Study

• Status: NOT_YET_RECRUITING
• Trial end date: 2026-02-01

Summary

This is an open, single-arm clinical study to observe and evaluate the efficacy and safety of first-line treatment of patients with stage C hepatocellular carcinoma of BCLC at HAIC in combination with adebrelimab and apatinib.

Patients with stage C hepatocellular carcinoma of BCLC who have not received prior systemic therapy and cannot be resected will be selected for the study. The study has objective response rate (ORR) as the primary study endpoint and is planned to enroll 33 subjects. Patients eligible for enrollment will receive HAIC in combination with adebrelimab and apatinib.

Subjects will receive study treatment after being fully informed and signing an informed consent form and being screened for eligibility.HAIC treatment (FOLFOX regimen) will be administered every 3 weeks until 6 treatments have been completed or HAIC treatment is terminated if the patient experiences intolerable adverse effects before 6 treatments have been achieved; adebrelimab, fixed dose 1200 mg, IV, D1, every 21 days (Q3W), in combination with Apatinib, 250 mg (0.25 g), orally, once daily (QD), administered consecutively in 3-week (21-day) treatment cycles. Study treatment will continue until the subject develops an intolerable toxic reaction, withdraws informed consent, and progresses in accordance with RECIST v1.1 disease progression as identified by the investigator (after the subject has progressed in accordance with the definition of RECIST v1.1, the subject may continue to receive study drug if the investigator assesses that the subject is still clinically beneficial and can tolerate the study treatment, or, if it is deemed that the subject no longer has clinical benefit, then treatment may be terminated), or other termination criteria specified in the protocol, whichever occurs first.

Subjects will all have a safety visit at D1 of each treatment cycle after enrollment in the study, and will continue to have a safety visit and survival follow-up after completion of treatment.

Tumor imaging assessment will be performed every 6 weeks after enrollment to assess efficacy. Additional imaging examinations and assessments may be performed at any time during the study if clinically indicated. Tumor imaging assessment will continue until there is disease progression confirmed by the investigator according to RECIST v1.1 criteria or termination of treatment, whichever occurs later. For subjects who end treatment for reasons other than investigator-confirmed disease progression (according to RECIST v1.1), regular follow-up tumor imaging assessments will also continue after the end of treatment.

If the subject withdraws consent, has started other anti-tumour therapy (other than PCPs) or dies prior to the occurrence of investigator-confirmed disease progression according to RECIST v1.1 criteria or termination of treatment, no further imaging assessment will be required. If the subject does not meet the above termination criteria for imaging assessment, the assessment of tumour efficacy for all three efficacy assessment criteria (RECIST v1.1, mRECIST, imRECIST) will need to be continued even if there is disease progression for one of the efficacy assessment criteria.
