Bio-Techne's Simple Western™ Technology Utilized in Recent FDA Approval of ZEVASKYN™ Cell-Based Gene Therapy
Rhea-AI Summary
Bio-Techne (NASDAQ: TECH) announced that its Simple Western™ Technology was instrumental in supporting the FDA approval of ZEVASKYN™, the first autologous cell-based gene therapy for recessive dystrophic epidermolysis bullosa (RDEB), developed by Abeona Therapeutics.
The Simple Western platform was chosen for its superior capabilities in detecting and quantifying Collagen VII, a critical protein for ZEVASKYN's potency testing. The technology's advantages include picogram-level sensitivity, reproducibility, and minimal sample requirements, making it essential for GMP-compliant lot release testing of both viral vector and cell therapy components.
The platform successfully overcame complex analytical challenges in standardization and assay development, particularly in evaluating Collagen VII's tertiary structure under non-denaturing conditions.
Positive
- Simple Western Technology proved crucial in FDA approval of first-in-class cell therapy
- Technology demonstrated superior capabilities in GMP-compliant testing and validation
- Successful partnership with Abeona Therapeutics enhances Bio-Techne's credibility in cell therapy development
Negative
- None.

Data tracked by StockTitan Argus on the day of publication.
Abeona selected Simple Western over competing methods like traditional western blot for its speed, reproducibility, picogram-level sensitivity, and minimal sample volume requirements. The platform effectively detected both the trimeric and monomeric forms of Collagen VII, addressing the analytical challenges posed by the protein's size and structure and supporting the regulatory requirements for potency and consistency.
RDEB is a rare and debilitating genetic skin disorder caused by mutations in the COL7A1 gene, which leads to the misfolding of Collagen VII, a protein essential for skin integrity. Patients with RDEB suffer from severe blistering, chronic wounds, scarring, and are at significantly increased risk of life-threatening complications such as squamous cell carcinoma. The current standard of care focuses on symptomatic management, with no durable therapies available until now.
The Simple Western platform provided quantifiable, GMP-compliant data to ensure consistency of each autologous ZEVASKYN product lot, overcoming key challenges in analytical standardization, limited sample availability, and complex assay development. Abeona's final assay design was optimized through rigorous antibody selection, assay optimization, and use of an appropriate reference standard – enabled by Simple Western's automated and high-throughput capabilities.
"ZEVASKYN represents a significant milestone for patients with RDEB and for the field of cell-based gene therapy," said Will Geist, Bio-Techne's President, Protein Sciences Segment. "We are honored that our Simple Western platform helped Abeona develop and validate critical potency assays that supported FDA approval of this first-in-class therapy."
"Potency method development and validation were critical components in the clinical development and regulatory approval of ZEVASKYN," said Dr. Ann Durbin, Senior Director of Quality Control at Abeona Therapeutics. "The Simple Western platform was the best choice for our quality control laboratories due to the reproducibility, time-to-result, and GMP compliance of the platform. We collaborated with Bio-Techne's ProteinSimple to address the challenges of our large molecular weight analyte, Collagen VII, and our requirement to evaluate the protein's tertiary structure under non-denaturing conditions. With the capillary electrophoresis platform, our validated assay efficiently quantifies Collagen VII to support both release testing of autologous ZEVASKYN lots, and the release and stability testing of our viral vector. The partnership of scientists at Abeona and at ProteinSimple was instrumental in advancing ZEVASKYN as the first approved cell-based gene therapy for patients with RDEB."
