CD19-CD28: an affinity-optimized CD28 agonist for combination with glofitamab (CD20-TCB) as off-the-shelf immunotherapyBlood · 2024
Summary (written by the submitters)
The study's objective is to investigate the mode of action of a bispecific CD19-targeted CD28 agonist (RG6333, CD19-CD28) in combination with the glofitamab through bulk RNA sequencing of tumor tissue from humanized mice over time. This analysis aims to describe the molecular and immunological changes induced by the combination therapy, which is designed to potentiate T cell-mediated antitumor activity.

Glofitamab, a T cell bispecific antibody, targets CD20-expressing malignant B cells and engages CD3ε to deliver a robust TCR signal. To enhance this effect, CD19-CD28 was developed to provide a necessary costimulatory signal by binding to CD19 on tumor-infiltrating T cells. This agent is engineered to require concurrent TCR signaling and CD19 target presence, avoiding the issues associated with previous superagonistic antibodies. In this study, we explore the synergistic potential of CD19-CD28 with glofitamab in activating T cell responses and inducing tumor regression in humanized mouse models. The RNA-Seq analysis identified gene expression signatures and immune pathways activated by the treatment. These findings underscore the promise of CD19-CD28 as an effective combination partner to glofitamab.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE260674_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1082717 and SRA study SRP492818. Searching any of these in the dataset finder brings you back here.
