Andelyn Biosciences and Purespring Therapeutics Partner to Manufacture Novel Gene Therapies for Kidney Diseases

COLUMBUS, OH, OCTOBER 20, 2023 - Andelyn Biosciences, Inc., a pioneering and patient-focused cell and gene therapy Contract Development and Manufacturing Organization (CDMO), has partnered with

Purespring Therapeutics, a biotech innovator company, to accelerate the manufacture of their gene therapies for the treatment of chronic renal diseases that are currently poorly addressed.

The partnership will enable Purespring to advance and accelerate clinical development of its portfolio of gene therapy programs targeting chronic kidney diseases.

Purespring is challenging the status quo by developing therapies that have the potential to stop or significantly slow down chronic kidney diseases. Through this partnership, Purespring will leverage Andelyn’s experience in adeno-associated virus (AAV) production and adapt Andelyn’s suspension platform to manufacture its innovative pre-clinical and clinical gene therapy products under GMP. The partnership will serve to maximize program efficiencies and accelerate timelines to the clinic.

The partnership between Purespring and Andelyn further strengthens their longstanding working relationship and offers great hope for patients suffering with chronic kidney diseases. Both organizations are aligned in their commitment to gene therapies and share the belief that these novel treatments will contribute meaningfully to the advancement of human health.

Matt Niloff, Chief Commercial Officer of Andelyn, commented: “Andelyn’s configurable AAV suspension platform is based on our vast database of historical data and decades of experience in viral vector development and quality manufacturing. We are honored to partner and serve as a key contributor to progress Purespring’s all-important kidney programs.”

Julian Hanak, CEO of Purespring, added: “Robust, high-quality manufacturing is absolutely critical to gene therapy. Purespring is excited to build on our longstanding working relationship with Andelyn to accelerate the pre-clinical and clinical manufacture of our innovative AAV-based gene therapies to help meet the unmet medical need of kidney disease patients worldwide.”

With continuation of its GMP manufacturing capabilities now at the new 185,000 sq. ft. Andelyn Corporate Center, Andelyn is proud to offer its clients exceptional quality and large-scale suspension clinical and commercial manufacturing in the now well-established Columbus, Ohio biotech hub. Andelyn also offers pre-clinical process development and plasmid manufacturing at its other two Columbus facilities.

About Purespring

Purespring is the first and leading company to treat kidney diseases by targeting the podocyte, a specialised cell implicated in many renal diseases, through AAV gene therapy administered directly to the kidney.

Purespring was founded on the work of Professor Moin Saleem, Professor of Paediatric Renal Medicine at the University of Bristol, where he heads a world leading multidisciplinary group researching glomerular diseases. Purespring seeks to advance gene therapies for the treatment of both monogenic and non-monogenic chronic renal diseases that are currently poorly addressed with existing treatments.

The company also has a proprietary in-vivo drug discovery functional selection platform, FunSel, a library of secreted biological factors combined with a screening method for the unbiased evaluation of drug candidates in disease models. FunSel allows Purespring to identify new gene therapy candidates and creates business development opportunities in other indications.
