LTX-315 and Adoptive T-cell Therapy in Advanced Soft Tissue Sarcoma


Brief description of study

This is a two part, single arm study designed to determine the safety and effectiveness of LTX-315 to induce T-cell infiltration prior to TIL expansion in patients with soft tissue sarcoma. Following intratumoural injection of LTX-315 to a selected lesion, the lesion will be extracted for T-cell culture, expansion and infusion.

Detailed Study Description

Patients with advanced/metastatic tumours who have received at least one approved standard of care treatment will be recruited. All patients must have at least two lesions, one that can injected with LTX-315 and another that can used to assess response. In the first part of the study, 4 doses of LTX-315 will be administered intratumorally over a two week period to an index lesion which will be biopsied or removed after treatment for T-cell expansion. The second part will involve culturing and expanding T-cells for infusion of tumour infiltrating lymphocytes (TILs) following an induction regimen. The safety and efficacy of the LTX-315 and TIL treatment will be assessed. Patients will be followed up for 15 months.
