Summary
Brief summary
This study aims to determine the safety and best response of treatment with CNA3103
(Leucine-rich repeat-containing G protein-coupled receptor 5 [LGR5]-targeted, Autologous
Chimeric Antigen Receptor (CAR) -T Cells), for participants with Metastatic Colorectal
Cancer.
Participants may undergo a pre-screening biopsy procedure to determine expression of LGR5.
Participants will undergo screening procedures, including leukapheresis (collection of T
cells) and lymphodepletion (chemotherapy), up to 47 days prior to CNA3103 dosing.
Participants will receive a single Intravenous dose of CNA3103.
Expansion cohorts will open after determination of the maximum tolerated dose and recommended
phase 2 dose in the dose escalation stage.
Participants will be followed up, monitored and will attend study visits for safety and
research related tests and procedures for 2 years until disease progression, unacceptable
toxicity or intolerable adverse event/s, death or withdrawal of consent.
