Clinical trials

This study is an open-label, dose-escalation and efficacy-expansion Phase I clinical trial designed to evaluate the safety, tolerability, pharmacokinetic (PK) profile, immunogenicity, and preliminary antitumor activity of QLS2401 as monotherapy in patients with advanced prostate cancer. The Phase I trial is divided into Phase Ia and Phase Ib components. The Phase Ia component involves a dose-escalation study of QLS2401 as monotherapy; should the results from the Phase Ia study meet the predefined criteria, a Phase Ib efficacy-expansion study of QLS2401 as monotherapy will be conducted.

This study is a first-in-human Phase 1 clinical study conducted in healthy adult participants in China to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of QLS2312 Injection after single and multiple subcutaneous administrations. The study consists of Part A and Part B: Part A is a single-ascending-dose study, and Part B is a multiple-ascending-dose (MAD) study.

This is a Randomized, Double-Blind, Placebo-Controlled, Single and Multiple Ascending Dose Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of QLS1510 in Healthy participants

The goal of this study aims to evaluate the efficacy and safety of QLS1317 in patients with MSI-H/dMMR advanced solid tumors who failed standard treatment.

The goal of this clinical trial is to evaluate the safety, tolerability, PK, and PD of single and multiple ascending doses of QLS12010 Capsules and the effect of food on their PK profiles in healthy adult participants and participants with atopic dermatitis. This study consists of four parts: Part A is a single ascending dose (SAD) study, once sufficient safety and PK data are obtained from the SAD cohorts, the SMC will determine the dosage of initial cohort in Part B, which consists of three multiple ascending doses (MAD) cohorts of QLS12010 Capsules. Part C is a randomized, open-label, two-cycle, crossover food effect study under fasting and fed (high-fat meal) conditions. Part D is to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) characteristics, and preliminary efficacy of QLS12010 Capsules following multiple oral administrations in adult participants with atopic dermatitis (AD).
