Conditions:
Digestive System Neoplasms
Eligibility:
All Genders
18-75 years
Phase:
PHASE1
Brief Summary
LP002 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 enh...
Eligibility Criteria

- Malignant digestive system neoplasms (mainly include gastric/ gastroesophageal junction/ esophageal carcinoma) failed (experienced progressed disease or unable to tolerate) at least one line of previously standard treatment for Arm I-A.
- Malignant gastric/ gastroesophageal junction carcinoma who are PD-L1 positive and failed (experienced progressed disease or unable to tolerate) at least two lines of previously standard treatments for Arm I-B.
- Metastatic gastric carcinoma who are PD-L1 positive and systemic treatment-naive for Arm I-C.
- Gastric or gastroesophageal junction carcinoma of cT2-4a, any N, M0 who are PD-L1 positive and systemic treatment-naive for Arm I-D.
- Advanced solid tumors (mainly include digestive system neoplasms) who failed (experienced progressed disease or unable to tolerate) at least one line of previously standard treatment or lack of standard treatments and has suitable lesions for intratumoral injection for Arm I-E.
- Has a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Score.
