Recruiting PHASE1 Osteosarcoma

Tests treatment safety and results for Osteosarcoma

Official title Safety and Efficacy of DIT309 in Advanced Bone and Soft Tissue Sarcomas

ClinicalTrials.gov ID: NCT07052383

What this study is testing

What is DIT309 cell injection?

DIT309 cell injection is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for osteosarcoma.

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
This is a open-Label, dose-escalation study to evaluate the safety, tolerability and antitumor activity of DIT309 in subjects with advanced bone and soft tissue sarcomas.The study also plan to explore the Maximum Tolerated Dose (MTD) and determine the Recommended Phase II Dose (RP2D) of the CAR-T cell therapy.
  • Phase 1: an early, usually small safety study
