Clinical Trial Summary

This is a Phase 1, open label, non-randomised, dose-escalation single agent study with expansion cohorts for dose confirmation/safety and preliminary efficacy of QLS31901 in advanced or metastatic malignancies

Description:

Study Design: This open label, multicenter, first in human study consists of 2 parts. Part 1 is a dose escalation to find the recommended dose for the expansion. Part 2 is a dose expansion to confirm the dose of QLS31901 through further evaluation of safety, tolerability, Pk, preliminary antitumor activity, and functional target engagement. The study includes three periods: Screening( up to 28 days prior to the first dose of study drug); Treatment(first dose of study drug with treatment cycles of 28 days); and Follow-up ( 30days 、60days and 90 days after the last dose) including survival follow-up checks every 3 months up to 12 months after the death of patient or the end of this clinical trial .
