Официальное название

Clinical Study on Evaluating the Safety and Tolerability of Bispecific Antibody MR001 in Patients With Advanced Solid Tumors.

Обзор

Phase 1 open-label study to evaluate the safety, tolerability and preliminary efficacy of bispecific antibody MR001 and to determine the maximal tolerated dose and designate the recommended phase 2 dose in subjects with locally advanced or metastatic solid cancers.

Подробное описание

Phase 1 open-label study to evaluate the safety, tolerability and preliminary efficacy of bispecific antibody MR001 and to determine the maximal tolerated dose and designate the recommended phase 2 dose in subjects with locally advanced or metastatic solid cancers. The study will be conducted in 2 parts: part 1 will involve dose escalation and part 2 will involve expansion of the recommended phase 2 dose.
