Official title
Sequencing-guided cHemotherapy Optimization Using Real-Time Evaluation in Newly Diagnosed DLBCL With Circulating Tumor DNA: SHORTEN-ctDNA
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to 1) determine whether it is feasible to measure circulating tumor DNA (ctDNA) in real-time during standard treatment for newly diagnosed diffuse large B-cell lymphoma (DLBCL), and 2) evaluate the outcomes of participants with undetectable ctDNA in the middle of treatment who receive a shortened course of chemotherapy. There are no investigational drug agents to be administered in this study. The investigational assay, phased variant enrichment and detection sequencing (PhasED-seq) will be used to guide de-escalation of standard-of-care therapy for newly diagnosed DLBCL. The PhasED-seq assay has not yet been approved by the Food and Drug Administration (FDA).
