A Study of Gentuximab + Paclitaxel in Patients With Advanced Gastric or Gastroesophageal Junction Cancer

19 mai 2026 mis à jour par: Changchun GeneScience Pharmaceutical Co., Ltd.

An Multi-center, Open-label Phase Ib/II Study of Gentuximab Injection + Paclitaxel in Patients With Advanced Gastric or Gastroesophageal Junction Cancer to Evaluate Tolerability, Safety, Efficacy and Pharmacokinetics.

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.

Description détaillée

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.
