Clinical Trial Summary

A study that aimed to assess the safety and anti-tumor activity of C-TCR055 injection in unresectable HCC patients

Description:

This study plans to enroll 5 patients to assess the safety of C-TCR055. Subjects who meet the eligibility criteria will receive a single dose of C-TCR055 injection, and will be followed up post treatment for safety monitoring. The follow up period will last 12 months.

Systemic therapy failed for HCC: those who received standardized systemic treatment for unresectable HCC and subsequently relapsed/progressed, or were intolerable or unwilling to receive treatment. Front-line system treatment should be approved in China (Sorafenib, lenvastinib, platinum-containing chemotherapy, regofinil); f. Previous systemic therapy was discontinued at least 2 weeks before apheresis; g. Local treatment (including surgery, ablation, interventional therapy, local radiotherapy, etc.) must be completed at least 4 weeks before apheresis, and there is no unhealed wound.

4. Has at least 1 measurable lesion as defined per RECIST v1.1; 5. HLA-A 02:01 allele positive; 6. Liver AFP expression IHC tests

3. Hemoglobin = 90g/L

4. Serum total bilirubin = 2 x ULN

5. Aspartate aminotransferase (AST) and alanine aminotransferase

6. Creatinine = 1.5 x ULN 12.If patient has previous HBV infection, patient should receive antivirals treatment following treatment guidelines during study period, and the HBV DNA copies should below the detection limit at screening.

Medium to severe ascites 6. subjects received other anti-tumor systemic therapies which were not recommended in guidelines. Or subjects received immunocheckpoint inhibitors which were discontinued less than 6 weeks or 2 drug half-lives before apheresis.

7. Subject has other primary cancer except for the following: A. Non-melanoma cured by excision, such as basal cell skin cancer. B.Cured in situ cancers such as cervical cancer, bladder cancer or breast cancer 8. Significant clinical gastrointestinal bleeding within 4 weeks before treatment. 9. Subjects with bone metastasis or central nervous system metastasis, or with hepatic encephalopathy, epilepsy, cerebrovascular accident and other central nervous system involvement diseases.
