Hepatic Arterial Infusion Chemotherapy (HAIC) Combined With Durvalumab and Lenvatinib in Patients With Locally Advanced or Metastatic Intrahepatic Cholangiocarcinoma: a Phase 2 Study(HAIC-quad Trial)

At present, the first-line treatment for patients with advanced unresectable intrahepatic cholangiocarcinoma is mainly systemic treatment, but the improvement in efficacy is limited and is not enough to meet the current clinical treatment needs. Hepatic artery infusion chemotherapy (HAIC) has the advantages of increasing local drug concentration and reducing toxic side effects compared to systemic intravenous chemotherapy. In order to enable patients with advanced intrahepatic cholangiocarcinoma to obtain better treatment effects, this study plans to explore HAIC combined with durvalumab and lenvatinib as the first-line treatment for patients with locally advanced or metastatic ICC, in order to provide a better treatment choice for their comprehensive treatment.

Proton Radiotherapy Plus Tremelimumab/Durvalumab for BCLC Stage B and C HCC

Tremelimumab plus durvalumab (STRIDE regimen) is an approved first-line therapy for unresectable hepatocellular carcinoma (HCC), yet it shows limited efficacy with an ORR of only 20.1%. Proton radiotherapy (RT), known for its precision and tissue-sparing advantages, has demonstrated improved survival outcomes and reduced toxicity compared to X-ray RT. Retrospective data suggest that combining proton RT with immune checkpoint inhibitors yields a promising ORR of 61.5%. Preclinical studies further support enhanced antitumor immunity when RT is combined with PD-L1 and CTLA-4 blockade. This phase II, single-arm clinical trial aims to evaluate the safety, efficacy, and immunologic effects of combining proton RT with tremelimumab and durvalumab in patients with unresectable HCC.

Evaluation of Efficacy and Safety of Immune Check Point Inhibitors in Hepatocellular Carcinoma Patients in Ain Shams University Hospitals

This study aims to evaluate the response to immunotherapy in HCC, assess the toxicity profile and measure overall survival within the study period. The primary end point is evaluation of progression free survival in HCC patients receiving immunotherapy. The secondary end point is to assess overall survival within the study period, duration of response and the response rate. The tertiary end point is to assess the toxicity profile.

Photon Radiotherapy Plus Tremelimumab/Durvalumab for BCLC Stage B and C HCC

Tremelimumab plus durvalumab (the STRIDE regimen) is an approved first-line therapy for unresectable hepatocellular carcinoma (HCC); however, it demonstrates limited efficacy, with an objective response rate (ORR) of only 20.1%. Radiation therapy (RT) is highly effective in controlling localized solid tumors and has become an integral component of the treatment algorithm for unresectable HCC. Preclinical studies have shown that combining RT with PD-L1/PD-1 blockade promotes immunogenic cell death and enhances antigen presentation by dendritic cells, thereby boosting systemic T cell-mediated antitumor responses in mouse models. The addition of CTLA-4 inhibition further enhances antigen cross-priming following RT. Recent retrospective data also indicate that combining RT with immune-oncology agents is associated with improved overall survival and prolonged time to progression compared to RT or immunotherapy alone. However, the clinical benefit and immunologic impact of combining RT with tremelimumab and durvalumab have not yet been evaluated in prospective clinical trials for unresectable HCC. This phase II, single-arm clinical trial aims to assess the safety, efficacy, and immunologic effects of combining proton RT with tremelimumab and durvalumab in patients with unresectable HCC.
