Imlifidase (INN), also known as IdeS, is an enzyme that depletes IgG antibodies fast and effectively. Hansa Medical is developing imlifidase as a proprietary treatment to enable kidney transplantation in sensitized patients, previously unable to undergo kidney transplantation due to the presence of anti-HLA IgG antibodies. Efficacy data reported from three Phase II studies (see Table 1 below) have demonstrated that imlifidase rapidly and significantly reduced anti-HLA antibodies, enabling kidney transplantation.

Imlifidase is currently being evaluated in two studies in highly sensitized patients that do not respond to available desensitization methods. Results from these studies are expected in late Q3 2018 and the goal is to submit applications for market approval, Biologics License Application (BLA) in the US and Market Authorization Application (MAA) in the EU, at the end of 2018 or early 2019.

The initiated long-term observational prospective follow up study (ClinicalTrials.gov Identifier: NCT03611621) aims to encompass all patients from the Phase II studies with imlifidase in sensitized kidney transplantation patients. The primary outcome measure of the study is evaluation of graft survival during a 5-year time frame in patients who have undergone kidney transplantation after imlifidase treatment.

The rationale for the study is to collect data from extended follow up in patients that have received a kidney transplant following imlifidase dosing to provide a better understanding regarding the long-term outcome for these patients. Data of parameters such as patient and graft survival as well as quality of life will be collected. This prospective, observational follow up study of patients who have received imlifidase prior to kidney transplantation will provide important information to future prescribers and patients on long-term outcome of imlifidase mediated transplantation.

About Hansa Medical
Hansa Medical is a biopharmaceutical company developing novel immunomodulatory enzymes for transplantation and acute autoimmune diseases. The lead product, imlifidase (IdeS), is a proprietary antibody-degrading enzyme currently in late-stage clinical development for kidney transplant patients, with significant potential for further development in other solid organ transplants and in acute autoimmune indications. The company also has a strong pipeline of preclinical projects that may provide a second wave of potential drugs. Under the project name NiceR, novel immunoglobulin-cleaving enzymes are developed for repeat dosing with the objective of applying the Hansa Medical technology in relapsing autoimmune diseases and oncology. Hansa Medical is based in Lund, Sweden, and its shares are listed on Nasdaq Stockholm (ticker: HMED).
