Autologous Natural Killer Cell Therapy for Hepatocellular Carcinoma

Phase 1

Recruiting

• Conditions: Hepatocellular Carcinoma
• Interventions: Drug: Autologous Natural Killer Cell Therapy; Device: Clinimacs Plus

• Registration Number: NCT06044506
• Lead Sponsor: Dr Cipto Mangunkusumo General Hospital

Brief Summary

This study represents a phase I clinical trial that utilizes natural killer (NK) cell therapy for patients diagnosed with liver cancer, specifically those classified as Child-Pugh A and falling within the Barcelona Clinic Liver Cancer (BCLC) stages B or C. The expected results include determining the suitable treatment dosage, identifying any resulting side effects, and calculating the average duration of progression-free survival. The target group for the study consists of all individuals diagnosed with liver cancer. At the same time, the practical sample consists of those who received medical care for liver cancer at Cipto Mangunkusumo Hospital (RSCM) between May and December 2022. The chosen research sample comprises liver cancer patients who fulfill the predetermined participation criteria. The necessary sample size for discerning appropriate treatment dosages and the occurrence rate of potential side effects shall consist of 2-3 liver cancer patients who are administered autologous NK cells. The process for isolating these NK cells adheres to the guidelines established by Miltenyi Biotec.

Arm && Interventions

Group	Intervention	Description
Autologous Natural Killer Cell	Autologous Natural Killer Cell Therapy	Dosage Form: Autologous Natural Killer (NK) Cells. These cells will be harvested from the patient's body and infused back into the patient. Dosage: The specific dose quantity will be determined based on the patient's medical condition and response to the treatment. Customized dosages will be calculated for each individual. Frequency: The treatment will be given through an intravenous method. Duration: The length of the treatment will vary depending on how the patient responds and their medical assessment. It may take several weeks to evaluate its effectiveness and potential impacts thoroughly.

Primary Outcome Measures

Name	Time	Method
Optimal treatment dosage	Start of infusion of Autologous NK cells (Day 0) until up to 6 months	To evaluate the safety of autologous NK cell infusion and discover dose-limiting toxicities (DLT). This evaluation will determine the recommended dosage for the next trial phase.

Secondary Outcome Measures

Name	Time	Method
Immunological Responses	Up to 6 months	Flow cytometry will evaluate infused NK cells' biomarkers, such as CD45 and CD56, that persist in peripheral blood. These biomarkers will be evaluated pre- and post-infusion.
Progression-free survival	Start of infusion of Autologous NK cells (Day 0) until progressive disease or death, whichever comes first, up to 2 years	This metric indicates the period during which a patient's condition shows no signs of progressing or deteriorating subsequent to the administration of autologous natural killer (NK) cell therapy
Tumor Shrinkage	Up to 6 months	CT scans will measure tumor size at baseline and specific post-infusion times. Tumor response will be assessed using mRECIST criteria.
Hematology Profile	Start of infusion of Autologous NK cells (Day 0) until up to 6 months	Changes of Complete Blood Count (CBC), Differential Blood Count, Coagulation Profile, Mean Alkaline Phosphatase (ALP), Alanine Amino Transferase (ALT), Aspartate Amio Transferase (AST) from baseline at each assessment time point
