Xintela receives 'intention to grant' decision from European Patent Office for stem cell product XSTEM

Using its unique marker technology and stem cell selection method, Xintela has developed a stem cell platform, XSTEM, for stem cell-based products. The company's first focus is treatment of osteoarthritis in the knee and is preparing to start clinical studies in 2021. XSTEM is also being evaluated in a preclinical model for the treatment of ARDS (Acute Respiratory Distress Syndrome), a lung complication that affects seriously ill covid-19 patients.

The company's European patent application no. 18703531.6, covering integrin 10-selected mesenchymal stem cells, has now received an intention to grant communication from the EPO. This means the EPO will grant the patent after fulfillment of certain administrative steps. The granted patent will confer protection for Xintela's stem cell product XSTEM in Europe until 2038. In addition to product protection, the patent also protects the use of XSTEM for the prevention and treatment of degenerative joint diseases such as osteoarthritis, bone sclerosis and degenerative disc disease (DDD) as well as traumatic cartilage and bone injuries.

- This is fantastic news that adds huge value to Xintela's stem cell business. A product patent that protects the stem cell product XSTEM, combined with our own GMP production facility, secures the development and commercialization of stem cell therapies from our stem cell platform for years to come, says Xintela's CEO Evy Lundgren-Åkerlund.
