Kiadis Pharma is developing its lead product candidate, ATIR101, for use in conjunction with haploidentical (genetically half-matched) hematopoietic stem-cell transplantations (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 2 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 through its own commercial organization in a first EU member state in the second half of 2019. In December 2017, Kiadis Pharma commenced an international, multicenter, randomized and controlled Phase 3 clinical trial of ATIR101 against the Post-Transplant Cyclophosphamide, (PTCy) protocol, the main protocol used to perform a haploidentical HSCT.
