The present invention relates to glypican-3-specific T-cell receptors. The present invention further relates to soluble TCR constructs, chimeric TCRs, bi-specific antibodies, nucleic acids, expression constructs and cells comprising said TCRs or TCR constructs. The present invention further relates to the use of the TCR or the soluble TCR constructs or chimeric TCRs or bi-specific antibodies as a medicament, preferably in the detection, diagnosis, prognosis, prevention and/or treatment of liver cancer, in particular hepatocellular carcinoma, or other cancers expressing GPC3. The present invention further relates to methods of detecting, diagnosing, prognosing, preventing and/or treating liver cancer, in particular hepatocellular carcinoma, or other cancers expressing GPC3. The present invention further relates to peptides comprising glypican-3 epitope(s) and respective nucleic acids encoding them, antibodies and compositions as well as their use as (peptide) vaccines. The present invention further relates to vaccines comprising the peptide(s).
