QLS-1304 for adults with advanced malignant solid tumors — Phase 1 dose escalation and expansion

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, open-label Phase 1 trial uses a dose-escalation stage followed by dose-expansion cohorts to characterize the safety, tolerability, pharmacokinetics, and preliminary efficacy of QLS-1304 monotherapy in adults with locally recurrent or metastatic malignant solid tumors. Eligible participants must have histologically confirmed disease, ECOG 0–1, at least one measurable lesion by RECIST v1.1, and adequate organ function. The dose-escalation portion will identify dose-limiting toxicities and a recommended dose, while expansion cohorts will explore early anti-tumor activity and further safety signals. Female participants of childbearing potential must have a negative pregnancy test and all participants must agree to effective contraception during treatment and for 180 days after the last dose.
