About Kiadis Pharma
Kiadis Pharma is developing its lead product candidate, ATIR101, for use in conjunction with haploidentical HSCT for adult blood cancers to address key limitations of haploidentical HSCT, without prophylactic immunosuppression and its associated morbidity and mortality. Based on the positive results from the single dose Phase II CR-AIR-007 study, the Company submitted a marketing authorization application to the European Medicines Agency in April 2017 for approval of ATIR101 as an adjunctive treatment in haploidentical HSCT for high risk adult hematological malignancies. If the product is conditionally approved, Kiadis Pharma intends to launch ATIR101 in Europe through its own commercial organization by year end 2019.

In December 2017, Kiadis Pharma commenced an international, multicenter, randomized and controlled Phase III clinical trial of ATIR101 against the Post-Transplant Cyclophosphamide, or PTCy protocol, the main protocol used to perform a haploidentical HSCT. The trial will be performed in 250 patients with acute leukemia and myelodysplastic syndrome at approximately 50 sites in the United States, Canada, Europe and certain additional countries. ATIR101 received regenerative medicine advanced therapy designation from the FDA in September 2017, which provides benefits that are materially equivalent to a breakthrough designation from the FDA. In addition, ATIR101 has been granted multiple orphan Drug designations both in the European Union and the United States.

The Company's shares are listed on Euronext Amsterdam and Brussels under the ticker KDS.
