Clinical Trial of TQB2868 Injection in Subjects With Advanced Malignant Tumors

• Status: Not yet recruiting
• Trial end date: 2024-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The TQB2868 protein in this study targeted programmed cell death protein 1 (PD-1) and transforming growth factor-β (TGF-β). The bifunctional fusion protein targets and neutralizes TGF-β in the tumor microenvironment. On the basis of inhibiting PD-1 / programmed death ligand 1 (PD-L1) pathway, T cells can restore activity, enhance immune response, and more effectively improve the effect of inhibiting tumor occurrence and development.

• Phase: Phase 1

6. People who have a history of psychotropic drug abuse and cannot be quit or have mental disorders;

7. Previous recipients of allogeneic bone marrow transplantation or solid organ transplantation.

8. Subjects with any severe and / or uncontrolled disease.

• 2 Tumor-related symptoms and treatment:

1. Have received chemotherapy, radiotherapy or other anti-cancer therapies within 4 weeks before the first medication (the washout period will be calculated from the end of the last treatment); if you have received local radiotherapy in the past, you can join the group if the following conditions are met: End of radiotherapy more than 4 weeks from the start of the study treatment (brain radiotherapy is more than 2 weeks); and the target lesion selected for this study is not in the radiotherapy area; or the target lesion is located in the radiotherapy area, but progress has been confirmed.

2. Received Chinese patent medicine treatment with anti-tumor indications specified in the National Medical Products Administration (NMPA) approved drug instructions within 2 weeks before the first medication;

2. Those who have had severe hypersensitivity reactions after using macromolecular drugs;

3. An active autoimmune disease that requires systemic treatment (such as the use of disease-relieving drugs, corticosteroids, or immunosuppressive agents) occurred within 2 years before the first medication. Alternative therapies (such as thyroxine, insulin, or physiological corticosteroids for adrenal or pituitary insufficiency, etc.) are not considered systemic treatments;
