Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of the study is to evaluate Tolerability, Safety, and primary Efficacy of Gentuximab Injection at different dosage in combination with Paclitaxel in Advanced Gastric or Gastroesophageal Junction Cancer patients, to ensure adequate treatment dosage for further study. Meanwhile, the study also evaluate Pharmacokinetics of Gentuximab Injection at different dosage in combination with Paclitaxel.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study includes dose-limiting toxicity (DLT)observing period and randomization period with two cohorts as low-dose group(Gentuximab Injection 8mg/kg+ paclitaxel) and high-dose group(Gentuximab Injection 12mg/kg+ paclitaxel). During the study,the anti-cancer efficacy, safety and anti-drug antibody were evaluated in all patients. DLT observation is only to subjects enrolled in DLT observation period and it lasts one treatment period. PK were doing in part of subjects.
