New treatment option for Select Advanced Solid Tumors
Official title A Phase 1/2 Study of KSQ-004EX, Autologous Tumor Infiltrating Lymphocytes Engineered to Inactivate Genes Encoding SOCS1 and Regnase-1, in Patients With Select Advanced Solid Tumors
ClinicalTrials.gov ID: NCT06598371
What this study is testing
What is Cyclophosphamide?
Cyclophosphamide is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for select advanced solid tumors.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Phase 1 is to find the recommended dose of KSQ-004EX to give to participants with advanced solid tumors. Phase 2 is to learn if KSQ-004EX at the recommended dose found in Phase1 can help to control advanced solid tumors.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
