Locally Advanced Unresectable or Metastatic Solid Tumors Clinical Trial
Official title:
A Phase Ia/Ib Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SG1906 in Patients With CLDN18.2-Positive Locally Advanced Unresectable or Metastatic Solid Tumors.
This is a Phase Ia/Ib Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SG1906 in Patients with CLDN18.2-Positive Locally Advanced Unresectable or Metastatic Solid Tumors.
After a screening period of up to 28 days for each study phase, qualified patients will be enrolled to receive their assigned dose of SG1906, administered every 2 weeks (Q2W), until disease progression or intolerable toxicity, starting of a new anticancer treatment, withdrawal of consent, lost to follow up, death, or end of the study, whichever occurs first. Phase Ia: Dose-escalation Stage The study population in Phase Ia includes patients with CLDN18.2-positive histologically or cytologically confirmed locally advanced unresectable or metastatic solid tumor who have relapsed after standard therapy, have failed standard therapy, are intolerant to standard therapy, are not eligible for standard therapy, or refuse standard therapy. Phase Ib: Dose-expansion Stage The study population in this phase will include patients with histologically or cytologically confirmed CLDN18.2-positive locally advanced unresectable or metastatic G/GEJ cancer or PC who have failed to respond to standard therapy, have relapsed after standard therapy, or are intolerant to standard therapy; and who have disease progression as confirmed by the Investigator or documented by medical history. ;
