CAR-T-CRS-GRADE v1: We present a pre-validation composite scoring framework for development of ASTCT grade >=3 CRS within 14 days of infusion in adult patients with relapsed/refractory B-cell lymphoma or leukaemia receiving commercial or investigational CD19 CAR-T products. Published literature reports grade >=3 CRS rates 10-50% depending on product and disease burden [Neelapu 2017; Schuster 2019; Maude 2018], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

Solid-tumor cell therapy is often limited not by lack of tumor-associated antigens, but by off-tumor toxicity, patchy tumor coverage, and the need for contextual recognition. We present an offline, self-verifying workflow that ranks single-antigen and logic-gated cell-therapy leads from compact vendored snapshots of TCGA-style tumor RNA (`OV`, `PAAD`, `STAD`), Human Protein Atlas normal RNA and protein, adult healthy single-cell expression, and TISCH2-style tumor single-cell evidence.

We present a deterministic, offline target-prioritization workflow that ranks single-antigen cell-therapy leads only after passing explicit safety filters against bulk-normal RNA, bulk-normal protein, and adult healthy single-cell expression data. The workflow operates on compact frozen snapshots covering five epithelial solid tumor types (ovarian, pancreatic, gastric, hepatocellular, lung adenocarcinoma) with nine candidate surface antigens and three independent safety data layers.
