JSKN022 in Subjects With Advanced Malignant Solid Tumors

Официальное название

A Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics/Pharmacodynamics, and Antitumor Activity of JSKN022 in Subjects With Advanced Malignant Solid Tumors

Обзор

The goal of this clinical trial is to learn if drug JSKN022 is safe to treat patients with advanced malignant solid tumors. It will also learn about the pharmacokinetic/ pharmacodynamic profiles and preliminary antitumor activity of drug JSKN022.

Подробное описание

This is a Phase I, open-label, multi-center, first-in-human (FIH) clinical trial designed to evaluate the safety, tolerability, pharmacokinetic (PK)/pharmacodynamic (PD) profiles, and antitumor activity of JSKN022 in patients with advanced malignant solid tumors.

Patients to be enrolled are with advanced unresectable or metastatic epithelial-derived malignant solid tumors confirmed by histology and/or cytology, who have failed previous standard treatment (disease progression), or be intolerant to standard treatment, or have no access to standard treatment.

The primary objective of the study is to evaluate the safety and tolerability of JSKN022 in patients with advanced malignant solid tumors and to determine the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D) of JSKN022.
