Kiadis Pharma files first investigational new drug application with the U.S. FDA for natural killer (NK) cell therapy produced with PM21

IND supports the Company’s planned NK-REALM Phase 1/2 study which will evaluate K-NK002 in 63 patients with blood cancer undergoing a haploidentical hematopoietic stem cell transplant (HSCT)

Amsterdam, The Netherlands, April 9, 2020 – Kiadis Pharma N.V. (“Kiadis Pharma” or the “Company”) (Euronext Amsterdam and Brussels: KDS), a clinical stage biopharmaceutical company, today announced that it has filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for the Company’s natural killer cell therapy product K-NK002. The IND covers the production of K-NK002 using Kiadis Pharma’s proprietary PM21 technology platform that enables high dose, low cost, scalable and industrial production of NK-cell therapy without the risk of residual tumor cells in the final product. The Company plans to initiate a Phase 1/2 study with leading transplant centers in the U.S. to evaluate K-NK002 once it receives FDA approval for the IND.  

Kiadis Pharma is developing K-NK002 as an adjunctive therapy to the current haploidentical HSCT standard of care with the goal of improving relapse rates. The Phase 1/2 study, called NK-REALM (haploidentical NK-cells to prevent post-transplant RElapse in AML and MDS), will evaluate the use of K-NK002 as an adjunctive therapy for blood cancer patients undergoing a haploidentical HSCT with the current standard of care, post-transplant cyclophosphamide (PTCy) protocol. The study, which will be conducted with the Blood and Marrow Transplant Clinical Trials Network (BMT CTN), will enroll 63 patients at leading transplant centers in the U.S. The study is designed to confirm earlier proof-of-concept data in 24 patients, which showed that adjunctive treatment with K-NK002 has the potential to substantially improve outcomes for patients in need of HSCT.

Arthur Lahr, CEO of Kiadis Pharma, commented, “The filing of this IND is an important step forward for Kiadis in bringing K-NK cell therapy to patients in need. Under normal circumstances, the FDA would take 30 to 60 days to review an IND, but given the current environment it is difficult to project a date for IND approval. Once approved, we are ready to immediately initiate the trial with the BMT CTN, and ramp up production of clinical materials.”
