Official title

A Biomarker Screening Protocol to Support Preliminary Eligibility for Clinical Trials Evaluating Safety and Efficacy of Adoptive T-cell Therapies in Participants With Solid Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Biomarker Screening Protocol for Preliminary Eligibility Determination for Adoptive T-cell Therapy Trials:This is a decentralized, multi-site, US-based biomarker screening study to identify participants who have specific disease indications and tumor expression of target(s) of interest that may inform eligibility for active and future Lyell clinical trials. No investigational treatments will be administered in this non-interventional screening study. Only previously obtained archival tumor tissue will be allowed on this study for biomarker analysis. Fresh tumor biopsies are not permitted on this study. The study will be conducted virtually and participants will utilize telehealth and e-consent modules. If participants tumors express the biomarkers of interest they can be referred to open and enrolling clinical trials. Participation on the screening study does not guarantee enrollment or treatment on an interventional clinical trial.
