Sunstone Life Science Ventures Fund IV invests in DiogenX, a biotech company developinga first-in-class regenerative treatment for type 1 diabetes

Copenhagen, Denmark and Marseille, France, Oct 31, 2023 – Sunstone Life Science Ventures (Sunstone), a leading European venture capital firm focused on life science therapeutics, today announced that Sunstone’s Fund IV has invested in the Series A financing round of DiogenX now increased to €33.5 million ($33.8M). In May, DiogenX, a biotech company focused on regenerating insulin-producing beta cells for the treatment of diabetes, had announced its initial Series A financing round.

DiogenX was founded in 2020 based on the groundbreaking research of Professor Patrick Collombat, a world-renowned expert in pancreatic beta cell regeneration. The Company’s lead program is a first-in-class recombinant protein that aims at replicating insulin-producing beta cells in the pancreas. This novel approach has the potential to offer a disease-modifying therapy for type 1 diabetes, a chronic and life-threatening condition that affects millions of people worldwide.

In this Series A round, Sunstone LSV Fund IV joins lead investors Roche Venture Fund and Boehringer Ingelheim Venture Fund (BIVF), alongside new investors Eli Lilly and Company and Omnes and existing investors JDRF T1D Fund and AdBio partners. The funding will enable DiogenX to advance its lead candidate towards clinical development.

We are very impressed by the scientific achievements and the vision of DiogenX’s team. We believe that their approach to regenerate beta cells has the potential to transform the treatment landscape for type 1 diabetes and to improve the lives of millions of patients” said Claus Andersson, General Partner at Sunstone and board member of DiogenX. “We are delighted to join this strong syndicate of specialized investors and to support DiogenX in its next phase of growth.

“Sunstone is a highly respected and experienced investor in the European biotech ecosystem. We are thrilled to have them on board as we work towards the clinic with our lead program,” said Benjamin Charles, co-founder and CEO of DiogenX. We are grateful for the continued support of our existing investors and the trust of our new investors. Together, we share a common vision to bring innovative solutions for patients with type 1 diabetes.
