Официальное название

A Single Center, Open, Single Arm Clinical Study on the Safety and Preliminary Efficacy of NK042 in the Treatment of Malignant Ascites

Обзор

The purpose of this study is to assess the safety and efficacy of NK042 for treatment of malignant ascites.

Подробное описание

This is a phase 1 ,open-label , Single Arm,dose escalation study to evaluate the safety, tolerability, PK, PD and preliminary efficacy of NK042 in patients with treatment of malignant ascites caused by Gynecologic Cancer.About 3-9 subjects are planned to be enrolled, Subjects will receive intraperitoneal infusion of NK042 once a week (D0、D7、D14)for 2 cycles, with 3 times during each cycle and a total of 6 infusions. The occurrence of DLTs will be observed from the first intraperitoneal infusion of NK042 to 28 days after infusion.

Вмешательства

• Препарат NK042
  NK042 intraperitoneal infusion on Days 0,7 and 14.
