New treatment option for Relapsed/Refractory
Official title A Study to Evaluate CG-105-12 in Patients With Relapsed/Refractory Multiple Myeloma
ClinicalTrials.gov ID: NCT06999031
What this study is testing
What is BCMA-Targeted Chimeric Antigen Receptor Autologous T-cell?
BCMA-Targeted Chimeric Antigen Receptor Autologous T-cell is an investigational medicine, being studied as a potential treatment for relapsed/refractory.
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 study is a single-centre, single-arm, open-label, dose-escalation exploratory study with single-dose administration. Its objective is to evaluate the safety, tolerability, dose, anti-tumor efficacy, and pharmacokinetic characteristics of CG-105-12 in the participants with BCMA-positive relapsed/refractory multiple myeloma who previously received adequate but uneffective standard treatments.
- Phase 1: an early, usually small safety study
