NCT04745403 | Recruiting Phase 1

• 1 other identifier: LTCR-HCC-3-3
• Study Type: interventional
• Target: 10
• Locations: 1 country

Brief Summary

This is a single center, single arm and open-label study to determine the safety of mRNA modified HBV-TCR redirected T-cells and to analyze the changes in tumor microenvironment caused by these HBV-TCR redirected T-cells in subjects with HBV-related HCC who are not amenable to/failed conventional treatment.

Conditions

Hepatocellular Carcinoma

Keywords

Hepatitis B virus; Hepatocellular Carcinoma

Outcome Measures

Primary Outcomes (2)

• Safety evaluation of mRNA HBV/TCR T-cell treatment

  Based on incidence and severity of adverse events

  Start of treatment until 28 days post last dose

• Analysis of modifications of tumour microenvironment caused by mRNA HBV/TCR T-cell treatment

  Histological staining using biopsy and analysis of serum factors such as cytokines and chemokines

  Start of treatment until end of study

Secondary Outcomes (3)

• Evaluation of anti-tumor efficacy of mRNA HBV/TCR T-cell treatment

  Up to 4 years

• Evaluation of anti-tumor efficacy of mRNA HBV/TCR T-cell treatment

  Up to 4 years

• Evaluation of anti-tumor efficacy of mRNA HBV/TCR T-cell treatment

  Up to 4 years

Study Arms (1)

mRNA HBV/TCR T-cells

EXPERIMENTAL

Escalating regime from 1x10e5 to 5-10x10e6 cells/kg bodyweight (BW) every 2 weeks.

Drug: mRNA HBV/TCR T-cells

Interventions

mRNA HBV/TCR T-cells DRUG

Study Infusion The first dose of mRNA HBV-TCR T-cells at dose 1x10e5/kg BW will be infused on Day 0, and subsequently incremental doses on Day 14 and 28, up to the dose of 5-10x10e6/kg BW.

mRNA HBV/TCR T-cells

Eligibility Criteria

• Age: 21 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Eastern Cooperative Oncology Group (ECOG) performance status ≤1
• Presence of primary hepatocellular carcinoma in the liver with presence of measurable tumour by RECIST 1.1 criteria, that is not amenable to, or failed, conventional treatment options
• Serum HBsAg positivity
• Non-cirrhotic or compensated cirrhosis Child-Pugh A (5 - 6 points)
• Life expectancy of at least 3 months
• HLA class 1 profile matching HLA-class I restriction element of the available T cell receptors (restricted by either HLA-A\*02:01 or HLA-A\*24:02).

You may not qualify if:

• Brain metastasis
• Second primary malignancy that is clinically detectable at the time of consideration for study enrolment, except for in situ carcinoma of the cervix, non-melanoma skin carcinoma localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer and superficial bladder tumors
• Use of immune checkpoint inhibitors and/or tyrosine kinase inhibitor (TKI) within 5 half-lives of the drug prior to baseline liver biopsy procedure
• Alterations of concomitant medications which could potentially cause drug induced liver injury and affect liver biopsy result within 3 months of baseline liver biopsy procedure.
• Likelihood to require any immunosuppressive treatments during the period of the clinical trial.
• \. Last RFA/TACE treatment within 3 months prior to first LioCyx-M infusion; Last Y90 therapy treatment within 6 months prior to first dose of mRNA HBV/TCR T-cells
• Decompensated cirrhosis Child-Pugh B or C (7 - 15 points)
• Concurrent administration of any other anti-tumour therapy, including cytotoxic chemotherapy, hormonal therapy, and immunotherapy.
• Use of any investigational product (IP) or investigational medical device within 30 days of study drug administration
• Serum HBV DNA levels ≥ 200 IU/ml at screening
• Serum HBsAg levels ≥ 10,000 IU/ml at screening
• Lack of peripheral venous or central venous access or any condition that would interfere with drug administration or collection of study samples
• Any condition or active infections which, in the investigator's opinion, makes the subject unsuitable for trial participation
• Women who are pregnant or breast-feeding
