A Phase I/II Clinical Study of CTS3497 in Patients With MTAP Deficient Malignacies

Официальное название

A Multi-center, Open-label, Phase I/II Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Anti-tumor Activity of CTS3497 in Patients With MTAP Deficient Advanced Solid Tumors and Lymphomas

Обзор

The primary objective of Phase I of this study is to evaluate the safety and tolerability, and to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of CTS3497 in patients with metastatic or locally advanced methylthioadenosine phosphorylase (MTAP)-deficient solid tumors and lymphomas. The primary objective of Phase II of this study is to evaluate the efficacy of CTS3497 in patients with metastatic or locally advanced MTAP-deficient solid tumors and lymphomas.

Подробное описание

The primary objective of Phase I of this study is to evaluate the safety, tolerability, PK, PD and efficacy to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of CTS3497 in patients with metastatic or locally advanced methylthioadenosine phosphorylase (MTAP)-deficient solid tumors and lymphomas.

The primary objective of Phase II of this study is to evaluate the efficacy and safety of CTS3497 in patients with metastatic or locally advanced MTAP-deficient solid tumors and lymphomas.
