Mts105 for Advanced Hepatocellular Carcinoma

Recruiting now · Phase 1

Conditions studied: Liver Cancer, Adult, Metastatic Liver Cancers, HCC - Hepatocellular Carcinoma, Hepatocellular Carcinoma (HCC)

In brief

This is the first-in-human trial of MTS105 (mRNA-LNP). The goal of this clinical trial is to evaluate the safety, tolerability of intravenous injection of MTS105 in advanced hepatocellular carcinoma.

You may qualify if…

• Histologically or cytologically confirmed diagnosis of hepatocellular carcinoma (HCC), excluding fibrolamellar or sarcomatoid subtypes, as well as mixed hepato-cholangiocellular carcinoma;
• Positive for GPC3 expression per immunohistochemical (IHC) staining.
• Failure of standard systemic therapies, including at least one immune checkpoint inhibitor and one targeted therapy (Tyrosine Kinase Inhibitors, and/or anti vascular endothelial growth factor agent).
• Presence of a measurable tumor lesion (per RECIST/ mRECIST criteria).
• Barcelona Clinical Liver Cancer Stage B or C (BCLC B/C)
• Child-Pugh Score ≤ 6
• ECOG score ≤ 1
• Adequate organ and bone marrow function as defined by the following laboratory criteria:
• Hematology: No blood transfusion or colony-stimulating factor therapy within 7 days prior to the first dose. The following hematological parameters should be met:Absolute neutrophil count ≥ 1.5 × 10\^9/L;Lymphocyte count ≥ 0.5 × 10\^9/L;Hemoglobin ≥ 90 g/L;Platelet count ≥ 75 × 10\^9/L;
• Liver function:Total bilirubin ≤ 2.5 mg/dL;Albumin ≥ 28 g/L;Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5 × ULN;

• Renal function:Serum creatinine ≤ 1.5 × ULN, or endogenous creatinine clearance ≥ 45 mL/min (as determined by the CKD-EPI formula);Urinary protein < 2+, or urinary protein ≥ 2+ but with 24-hour protein quantification ≤ 1.0 g
• Cardiac function:Left ventricular ejection fraction (LVEF) ≥ 50%; No clinically significant abnormal ECG findings (chronic atrial fibrillation is allowed, provided it does not require medication);
• Capable of full communication with the investigator, with the ability to understand and comply with study requirements, and able to understand and sign the informed consent form (ICF).
• ≥18 years
