Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: EARLY_PHASE1
• Study Classification: INTERVENTIONAL
• Study Start Date: 2024-08-28
• Study Completion Date: 2026-07-31

Brief Summary

The goal of this clinical trial is to learn about the safety of CD-801, a lipid nanoparticle-encapsulated self-replicating RNA encoding hepatocyte nuclear factor 4α (HNF4α) in treating patients with advanced intrahepatic cholangiocarcinoma (ICC). It will also learn if CD-801 works to treat advanced ICC. The main questions it aims to answer are:

1. What medical problems do participants have when injecting CD-801?

2. Is CD-801 effective for ICC patients according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or modified RECIST (mRECIST)

Participants will:

Receive administration of 100μg of CD-801 via hepatic arterial injection every 14 ± 3 days (the dosing interval will be adjusted based on the tolerability, safety, and therapeutic effect of the subjects), for one treatment cycle. Treatment will continue until the occurrence of disease progression, death, intolerable toxicity, voluntary withdrawal of informed consent, loss to follow-up, initiation of new antitumor treatment, or termination of the study by the investigator (whichever comes first), and completion of the final follow-up and assessment 14 days after the last administration.

Eligibility Criteria

Inclusion Criteria

• Males or females, aged 18 years or older.
• Histologically or cytologically confirmed intrahepatic cholangiocarcinoma patients.
• Patients with intrahepatic cholangiocarcinoma not suitable for surgical resection, liver transplantation, or ablation therapy, or those with post-surgical recurrence and/or metastasis.
• Patients not suitable for local or systemic treatment, or those who have progressed after at least one chemotherapy regimen containing gemcitabine/fluoropyrimidine/platinum, etc..
• Life expectancy of 12 weeks or more.
• Subjects must have an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 to 2.
• Males with fertility and females of childbearing potential are willing to use a highly effective method of contraception for the entire study period and for 6 months after study drug discontinuation. Females of childbearing age, including premenopausal females and within 2 years after menopause, must have a negative serum pregnancy test result within 7 days prior to the first dose of study treatment.
• Subjects who had a voluntary agreement to provide written informed consent and the willingness and ability to comply with all aspects of the protocol.

Exclusion Criteria

• Patients with any of the following criteria were excluded from participation in this study:

• Inadequate liver function：Albumin (ALB) < 25 g/L, or total bilirubin > 5 × the upper limit of normal (ULN), or aspartate aminotransferase (AST), alkaline phosphatase (ALP), or alanine aminotransferase (ALT) >10 × ULN.
• Inadequate renal function defined as creatinine >1.5 × ULN or calculated creatinine clearance < 40 mL/min.
• Absolute neutrophil count (ANC) < 1.0×109/L, or Platelets < 30×109/L, or Hemoglobin < 8.5 g/dL.
• International normalized ratio (INR) > 2.3.
• Poorly controlled hypertension, diabetes or other serious heart or lung diseases, or with serious dysfunction.
• Patients who have received local or systemic anti-tumor treatments such as ablation, Transhepatic Arterial Chemotherapy and Embolization (TACE), local radiotherapy of the liver, immunotherapy, targeted therapy, etc., within 4 weeks, or chemotherapy, other trial drugs, or radiotherapy of metastatic lesions within 2 weeks, except for treatment regimens assessed as disease progression according to mRECIST or RECIST 1.1.
• Patients with uncurable brain metastasis.
• All toxicities related to prior locoregional or systemic anti-tumor treatments are still grade 2 or more (except for hair loss and other events that have been judged tolerable by researchers).
• Complication histories of liver cirrhosis or HCC such as gastrointestinal hemorrhage, overt hepatic encephalopathy, or refractory ascites within 2 weeks prior to the first dose of study treatment.
• Uncontrolled active infection (eg, lung infections, or abdominal infections).
• History of malignancy other than HCC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year overall survival rate > 90%), such as adequately treated early gastric carcinoma, carcinoma in situ of the cervix, non-melanoma skin carcinoma, or localized prostate cancer.
• Hepatitis B virus DNA greater than 500 copies/mL, or hepatitis C virus RNA greater than 15 U/mL.
• Positive for human immunodeficiency virus (HIV).
• Allergic to contrast agents.
• Pregnant/lactating women, or women with the possibility of pregnancy.
• Any medical conditions which, in the opinion of the investigator, would preclude participation in this clinical trial.
