Overview
Brief Summary
The goal of this investigator-initiated, a single-arm, open-label, pilot study is to investigate the safety, tolerability, and efficacy of intravenous HNF4α srRNA treatment in subjects with advanced Intrahepatic Cholangiocarcinoma (ICC).
Condition of disease: advanced intrahepatic cholangiocarcinoma Intervention： HNF4α srRNA will be administered intravenously for the treatment of ICC. The dosing regimen is planned for a second dose 14 ± 3 days post-initial treatment, followed by subsequent treatments every 28 ± 7 days, with adjustments made based on patient tolerance and therapeutic response. This is a dose escalation assay employing a i3+3 design to assess escalating HNF4α srRNA dosages: 25 μg, 50 μg, and 100 μg. Post-initial dose, a 14-day dose-limiting toxicities (DLT) observation will evaluate tolerability and safety, guiding dose adjustments or selection of the Recommended Dose (RD) for the expansion phase. Cohorts may include up to 9 participants, adjusted for safety.
Drug: HNF4α srRNA, a drug specifically designed to target liver cancer cells and facilitate the expression of HNF4α.
According to Amendment 1, patients who have received at least 4 cycles of HNF4α srRNA therapy and have a tumor assessment of SD (stable disease) or PD (progressive disease) per RECIST v1.1 criteria may, after a comprehensive evaluation by the investigator considering the patient's treatment history and the current safety and efficacy data of HNF4α srRNA, continue HNF4α srRNA at the same dose, or have their dose adjusted, in combination with immunotherapy, targeted therapy, or chemotherapy.

Arms & Interventions
HNF4α srRNA treatment
The subjects with advanced ICC will be treated by HNF4α srRNA intravenously via a peripheral vein. According to Amendment 1, the HNF4α srRNA preparation CD-801 used in the original protocol will expire on December 31, 2024. For participants receiving treatment after this date, the preparation will be switched to CD-GA-102, with the treatment dose converted on a 1:1 basis.
Intervention: HNF4α srRNA
Outcomes
Primary Outcomes
To evaluate the tolerability and safety for intravenous HNF4α srRNA in subjects with intrahepatic cholangiocarcinoma (ICC)
Time Frame: Through study completion, an average of 2 years
Safety and tolerability are assessed based on the incidence of Dose-Limiting Toxicities (DLTs) within 14 days post-initial drug administration, along with the frequency and severity of adverse events (AEs), serious adverse events (SAEs), and events leading to treatment discontinuation throughout the treatment period, all evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. According to Amendment 1, the primary endpoint has been amended from assessing the incidence and severity of DLTs, adverse events (AEs), serious adverse events (SAEs), and AEs leading to treatment discontinuation (evaluated per NCI-CTCAE 5.0) with HNF4α srRNA therapy to assessing these outcomes for both HNF4α srRNA monotherapy and combination therapy.
Secondary Outcomes
- To assess the objective response rate (ORR) by RECIST v1.1(From the first study dose date until the date of documented complete response or partial response, assessed up to 24 months.)
- Duration of response based on RECIST v1.1(up to 24 months)
- Progression-free survival based on RECIST v1.1(up to 24 months)
- Time to response based on RECIST v1.1(up to 24 months)
- Clinical benefit rate based on RECIST v1.1(up to 24 months)
- Overall Survival(Throughout the entire course of treatment until the end of the follow-up period, an average of 2 years)

- Patient Reported Outcome-2(Through study completion, an average of 2 years)
- Patient Reported Outcome-3(Through study completion, an average of 2 years)
