Preclinical Validation and Manufacture of IL-8 Receptor-Modified CD70 CAR T Cells for Clinical Trial
Abstract describing the preclinical validation of IL-8 receptor-modified CD70 CAR T cells. The G-Rex® system was used for ex vivo expansion, achieving approximately 1200-fold expansion in 2 weeks. The optimized process allows for clinical scale production using small blood volumes.

A multivariate, quantitative assay that disentangles key kinetic parameters of primary human T cell function in vitro
The authors developed the QuIK assay to measure proliferation and killing kinetics of engineered T cells. Primary human T cells were transduced and expanded in 24-well G-Rex® plates. The assay provides detailed insights into the functional biology of CAR-T and TCR-T cells over time.

Photodepletion with 2-Se-Cl prevents lethal graft-versus-host disease while preserving antitumor immunity
This research demonstrates that photodepletion with 2-Se-Cl selectively removes alloreactive T cells to prevent GVHD without compromising antitumor immunity. G-Rex® devices were utilized for the initial co-culture and priming of splenocytes before the photodepletion step.

Characterization of a Cytomegalovirus-Specific T Lymphocyte Product Obtained Through a Rapid and Scalable Production Process for Use in Adoptive Immunotherapy
This study characterizes CMV-specific T lymphocytes (VSTs) expanded rapidly for adoptive immunotherapy. Using G-Rex® technology with IL-2, IL-7, and IL-15, researchers achieved a scalable process yielding functional, cytotoxic T cells. The method ensures high specificity and safety for treating viral infections.

Development of an optimized closed and semi-automatic protocol for Good Manufacturing Practice manufacturing of tumor-infiltrating lymphocytes in a hospital environment
The authors developed a GMP-compliant TIL expansion protocol using G-Rex® and the Xuri bioreactor. Pre-REP expansion in G-Rex® resulted in higher cell numbers compared to 24-well plates. The closed-system process reduced operator time and produced functional TILs suitable for clinical trials.

Inhibition of MICA and MICB Shedding Elicits NK cell–mediated Immunity against Tumors Resistant to Cytotoxic T cells
The study demonstrates that blocking MICA/B shedding enables NK cells to target tumors with MHC-I or IFN-gamma pathway mutations. Human NK cells were expanded in vitro using G-Rex® 6-well plates. This therapeutic strategy effectively reduced metastases in humanized mouse models.

Optimization and Scale-up of Treg Expansion from CD4+ Cells in G-Rex®6M plates
This poster details the optimization of Treg expansion using Cloudz™ Treg CD3/CD28 microspheres. The method achieved high purity and cell numbers. Scalability was demonstrated using G-Rex®6M plates, which utilize a gas-permeable membrane to support efficient cell growth in serum-free media.

Detection of response to tumor microenvironment–targeted cellular immunotherapy using nano-radiomics
This study explores nano-radiomics to assess response to MDSC-directed NK cell therapy in solid tumors. Human NK cells were activated and expanded in G-Rex® devices for in vivo testing. Radiomic analysis of CT images successfully identified treatment responses that conventional tumor metrics failed to detect.

Generation of Antitumor T Cells For Adoptive Cell Therapy With Artificial Antigen Presenting Cells
This study develops renewable artificial antigen presenting cells (aAPCs) for T cell expansion and transduction. Using G-Rex® , aAPCs supported efficient production of CAR T cells and TILs with less exhaustion and higher potency than bead-based methods, offering a cost-effective manufacturing alternative.

Rapidly expanded partially HLA DRB1–matched fungus-specific T cells mediate in vitro and in vivo antifungal activity
The authors describe a GMP-compliant method to rapidly expand fungus-specific T cells using CD137 selection and short-term culture. G-Rex® cell culture plates were used for the in vitro expansion of the enriched CD137+ population. The resulting T cells demonstrated potent antifungal activity against Aspergillus.

Head- to- head comparison of in- house produced CD19 CAR- T cell in ALL and NHL patients
This study compares in-house produced CD19 CAR-T cells for ALL and NHL. Cells from ALL patients expanded better. Production utilized G-Rex®100 , enabling rapid generation of therapeutic doses. The study highlights phenotypic differences based on the patient's disease.
