Overview
This is a Phase I open-label study that will evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of HWS116 monotherapy in patients with advanced solid tumors.
Description
This trial is an open-label, dose-escalation/expansion first-in-human study of HWS116, divided into two parts:
Part 1 (Dose Escalation): This part plans to enroll patients with advanced solid tumors who have no standard treatment, have failed standard treatment, or are ineligible for standard treatment. Patients will receive monotherapy with HWS116 at pre-specified escalating doses. The objectives are to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of HWS116 in patients.
Part 2 (Dose Expansion): This part intends to enroll patients with advanced solid tumors who have no standard treatment, have failed standard treatment, or are ineligible for standard treatment. Patients will receive continuous administration of HWS116 to provide additional clinical data for evaluating preliminary efficacy and determining the Phase 2 recommended dose (P2RD) and potential indications.

- Have autoimmune diseases, immunodeficiencies, a history of organ transplantation, or are planning to undergo organ transplantation;
- Presence of any severe, uncontrolled clinical issues (e.g., uncontrolled malignant pleural effusion, ascites, pericardial effusion, or unstable psychiatric conditions) deemed unsuitable for study participation by the investigator；
- Have acute inflammation or clinically significant active infections;
- Have a history of alcohol abuse or drug abuse;
