Genomics from LCCC1525: A Priming Dose of Cyclophosphamide Prior to Pembrolizumab to Treat mTNBC
This phase II, single-arm, multicenter study will evaluate pembrolizumab therapy, 200 mg IV, given every 3 weeks (Q3W), following a single priming dose of cyclophosphamide, 300 mg/m2 IV, in patients with advanced triple-negative breast cancer (TNBC) who have received at least one prior line of therapy. Data uploaded consists of FASTQ sequencing data from tumor RNASeq (pre-pembrolizumab), tumor and normal tissue WES, and sequencing for targeted T and B cell chains (TRB, IGK, IGL, IGH) from peripheral blood at various timepoints: pre-, post-, and during pembrolizumab therapy.
