Study of SC-102 in Patients With Advanced Solid Tumors

Официальное название

Phase Ⅰ Study to Evaluate the Safety/Tolerability, Pharmacokinetics, and Efficacy of SC-102 in Subjects With Advanced or Metastatic Solid Tumors That Express EphA2

Обзор

This study will evaluate the safety, PK profile, and anti-cancer efficacy of SC-102 in subjects with advanced solid tumors

Подробное описание

SC-102 is a peptide drug conjugate (PDC) consisting of an EphA2-targeting peptide, a tubulin inhibitor, and a protease-hydrolysable linker.

This phase I multi-center, open-label first-in-human trial, including a dose escalation study and a dose expansion study, will evaluate SC-102 administrated once weekly or biweekly as a single agent in patients with advanced solid tumors. The dose escalation study is primarily designed to assess the safety and tolerability of SC-102 and to determine the recommended dose(s) for the dose expansion study. The dose expansion study is designed with the primary objective of evaluating the clinical activity of SC-102.
