A Study of TQB2450 Injection Combined With Stereotactic Body Radiation Therapy (SBRT) in Subjects With Advanced Oligometastatic Non-Small Cell Lung Cancer

• Status: Not yet recruiting
• Trial end date: 2023-05-30
• Target enrollment: 0
• Participant gender: All

Summary

TQB2450 is a humanized monoclonal antibody targeting programmed death ligand-1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

4. Has received standard first-line chemotherapy, intolerable or inappropriate to the chemotherapy.

5. Adequate organ system function. 6. Male or female subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 6 months after the last dose of study (such as intrauterine devices , contraceptives or condoms) ；No pregnant or breastfeeding women, and a negative pregnancy test are received within 7 days before the first administration.

7.Understood and Signed an informed consent form.

Exclusion Criteria:

• 1. Has used against PD-1, PD-L1 and other related immunotherapeutic drugs. 2.Has mutations in (epidermal growth factor receptor)EGFR, (anaplastic lymphoma kinase)ALK, (c-ros oncogene 1 receptor kinase)ROS1 or T790M and not resistant to targeted drug.
