Clinical trials

The purpose of this study is to explore the efficacy and safety of Ivonescimab in combination with GEMOX chemotherapy as neoadjuvant and conversion therapy for patients with biliary tract cancer. It aims to evaluate the impact of this combination regimen on postoperative recurrence, patient survival, and medication safety. This is a single-center, phase II, interventional, single-arm, multi-cohort clinical study. A total of 87 eligible participants will be enrolled and assigned to either the neoadjuvant therapy cohort (45 participants) or the conversion therapy cohort (42 participants).

The purpose of this study is to explore the effects of sacituzumab tirumotecan combined with pembrolizumab on survival, disease progression, and safety in patients with advanced biliary tract malignancies in the second-line and later settings. This is a multicenter, phase II, interventional single-arm clinical study. A total of 38 participants will be enrolled. Participants will receive the combination therapy until disease progression or unacceptable toxicity.

This is a prospective, single-arm, phase II clinical study. Patients with advanced cholangiocarcinoma harboring FGFR2 fusions or rearrangements who have either not previously received standard therapy or have experienced treatment failure following standard therapy will be screened for eligibility and enrolled in the study after providing written informed consent.

Hepatobiliary malignancies-principally hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA)-are highly aggressive and often diagnosed at advanced stages. Curative-intent liver resection remains the standard for resectable disease; however, postoperative outcomes depend on an adequate functional future liver remnant (FLR). Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) induces rapid FLR hypertrophy and has expanded resection eligibility compared with conventional two-stage hepatectomy by shortening the interval to definitive resection. Key uncertainties persist regarding the quality of ALPPS-induced regeneration and its relationship to long-term oncologic outcomes, including recurrence and metastasis. This observational study enrolls patients deemed suitable for ALPPS at Peking Union Medical College Hospital. Perioperative care follows institutional standards; no therapeutic procedures are altered for research purposes. The investigators will collect clinically available liver tissue and relevant medical data obtained during standard surgical care to characterize cellular and molecular programs of regeneration across the ALPPS stages. High-throughput profiling-including single-cell and spatial transcriptomics-will be used to define cell-type composition, transcriptional states, and signaling pathways associated with regeneration. The primary objective is to describe cellular and gene-expression changes in regenerating liver induced by ALPPS. Secondary objectives include exploring associations between regenerative quality and short- and long-term clinical outcomes. Findings are expected to inform potential therapeutic targets and strategies to enhance safe regeneration and improve postoperative prognosis.
