Switzerland, 14 February 2024 – CUTISS AG, a Swiss clinical-stage life science company focused on skin regenerative medicine and tissue engineering, has announced positive one-year follow-up data from its Phase 2 clinical trial of the lead product denovoSkin™, in adult and adolescent severe burn patients. Following the announced positive primary endpoint in Q1 2023, the one-year readout evaluated long term safety and scar quality. Dr Daniela Marino, CEO of CUTISS, commented: “The latest data represent a pivotal moment in our mission. It reinforces the evidence we have gathered so far that denovoSkin™ can be life-saving and can become a transformative treatment option for patients suffering from severe burns by improving overall scar quality and relief post grafting.”  The Phase 2 data and results thus far demonstrate that denovoSkin™, a living, personalized bilayer (with epidermis and dermis) bioengineered skin graft, can safely cover severe burn wounds, significantly sparing patients’ healthy donor sites while improving overall scar quality when compared to standard of care intra-patient. Prof. Dr. MD, Martin Meuli, Chairman of CUTISS, added: “The accomplishments of the past decade have placed us in the midst of an important paradigm shift in burn treatment: from mortality, that used to be the primary concern, to areas that focus on the quality of life of burn survivors. Conceptually understanding the epidermis as “life” whereas dermis as “quality of life” is maybe simplistic, but nonetheless useful to understand the impact that denovoSkin™ can potentially have in burn surgery.”   The current treatment in severe burns and reconstructive surgery – autografting – commonly results in permanent painful, debilitating, disfiguring scars that frequently require follow up corrective surgeries, psychosocial rehabilitation and intense home care. With denovoSkin™, CUTISS is seeking to revolutionize the treatment of severe burns. The Phase 2 clinical trial in adult and adolescent burns has a long-term follow-up of three years (data will be available in 2025). A total of 15 patients were included in this trial. The company is preparing for the next regulatory steps, aiming to make denovoSkin™ available to patients suffering from severe burns and skin injuries worldwide.

CUTISS achieves full independence in its manufacturing capabilities with onsite facility. Increased agility and capacity in producing denovoSkin for current and future clinical trials and patients on compassionate basis. Successful transfer of technology and departure from Wyss Zurich Translational Center, a joint accelerator created by Hansjörg Wyss together with the University of Zurich and ETH Zurich (Swiss Federal Institute of Technology Zurich). Zurich, Switzerland – 08 March 2022 – CUTISS AG, a Swiss clinical-stage life sciences company focused on regenerative medicine and skin tissue engineering, has announced the start of production at the company’s new onsite manufacturing facility. This follows the certification of compliance for Good Manufacturing Practices (GMP) and Good Distribution Practices (GDP)[1] from the regulator Swissmedic, the Swiss Agency for Therapeutic Products, in October 2021, and then the authorization to transfer the technology from Wyss Zurich to CUTISS. Kathi Mujynya, Chief Operating Officer at CUTISS, said: “This evolution represents a critical milestone for CUTISS. It centralizes our activities around the manufacturing of denovoSkin, increases our production capacities, and enables us to scale up the manufacturing process and take our automation program to the next level.” The CUTISS facility has commenced manufacturing and testing of tissue-engineered products, notably for the personalized human skin tissue therapy denovoSkin which is currently in Phase 2 clinical trials. The state-of-the-art facility, located at the company’s headquarters at the Biotechnopark in Zurich-Schlieren, covers a surface area of 150 square meters and is comprised of several laboratories including a biobank and a histology lab. Until now, CUTISS’s products were manufactured at the GMP facility of Wyss Zurich Regenerative Medicine Technologies Platform, University of Zurich. Following the successful transfer of technology, CUTISS has become one of the first regenerative medicine companies to transfer out of this platform at Wyss Zurich. Professor Simon P. Hoerstrup, Founding Co-Director of the Wyss Zurich Translational Center, stated: “We are extremely pleased with the development of the project during its five years at Wyss Zurich, not least because it has all come out of our own development at the University of Zurich, our state-of-the-art technical and scientific platform facilities, and the Children’s Hospital Zurich. Starting as a research project, moving to preclinical implementation, and finally to clinical trials in a highly regulated environment – this is one of Wyss Zurich’s flagship projects. And finally, a successful technology transfer from Wyss Zurich’s Regenerative Medicine Technologies Platform to the startup was achieved with the construction of its own facility by CUTISS.” Dr Daniela Marino, Chief Executive Officer at CUTISS, commented: “We are very grateful to Wyss Zurich for their help and support throughout the last five years, enabling CUTISS to grow and arrive at this stage of development. Now, we are thrilled to have established and launched our own independent manufacturing capabilities, enabling us to scale up the development of our personalized skin tissue therapy and to meet the needs of patients with severe skin injuries.” Today’s announcement coincides with CUTISS’s five-year anniversary, having been established on 08 March 2017.
